"I've changed a lot since I started hanging out with Sonic, but I can't depend on him forever. I know I can do this by myself!"

- Miles "Tails" Prower, Sonic Adventure

Miles Prower (マイルス・パウアー), better known by his nickname, Tails (テイルス), is a fictional character from the Sonic the Hedgehog series. He is an anthropomorphic eight-year-old fox cub born exclusively with two twin-tails, hence his nickname. Because of his abnormality, Tails was the subject of bullying during his youth. One day however, he met Sonic the Hedgehog and was inspired to become as cool as him after seeing him run like the wind. Tails soon after began following Sonic on his adventures and has since become his best friend and sidekick. He is able to use his twin-tails to fly by rotating them like helicopter rotors and is a mechanic genius and aerial pilot.

A gentle and sweet-natured soul, Tails was initially timid and lacked courage. After meeting Sonic, however, Tails became more confident about himself, eventually growing up to be a more outgoing, brave and independent individual and a hero in his own right. Since encountering Sonic, Tails has looked up to him and stood by his side, helping him however he can during their adventures.

According to official polls, Tails is the third most popular character of the series, behind Sonic and Shadow.

Concept and Creation
The concept for Tails was founded during the development of Sonic the Hedgehog 2. After some discussion about making a sequel to Sonic the Hedgehog (1991), portions of Sonic Team went to work with Sega of America's Sega Technical Institute. A new element they wanted to introduce was a new character that would both serve as a sidekick to Sonic the Hedgehog and draw attention and new players to the franchise.

An internal contest was held at STI which Yasushi Yamaguchi, originally the main artist and zone designer for Sega's Sonic Team, won. Yamaguchi originally created Ray the Squirrel (who would only appear in SegaSonicArcade) to be used as a sidekick, but designed Tails for the internal competition after Sega of Japan rejected the Flying Squirrel idea. The character was meant to hold a "deep admiration for Sonic."

The name 'Miles Prower' played on a speed pun (miles per hour) and was originally intended to be a tanuki, a raccoon-like canine native to east Asia, and extremely popular in Japanese folklore. The designers decided to change him to a fox, however, to avoid possible comparisons with Mario, who at the time had a power up called the Tanooki Suit, which allowed him to fly, and made him look like a tanuki. His entry won, but Sonic Team decided to change his character's name from "Miles" to "Tails" in which Yamaguchi was not too pleased at all about. Yamaguchi ended up with a compromise: he put the name "Miles" in as his legal name; "Tails" would be his nickname, ending up with the full name of Miles "Tails" Prower.

The character debuted as Sonic's tag-along partner in the franchise's second game, and has remained an important character. However Tails' uniqueness was not established until Sonic the Hedgehog 3 when players were allowed to control his flying.

Tails was redesigned (along with all of the other Sonic characters) by Yuji Uekawa for Sonic Adventure. Tails' redesign saw him having his fur color changed to a slightly orange shade of yellow, and he gained visible blue irises. He also became slightly slimmer and taller. He also gained a more streamlined appearance with slightly more rounded ears as well as longer tails, which are used as his main form of attack, most notably the Tail Swipe.

Early Life
Almost nothing is known about Tails' early life. What is known is that Tails was born with the genetic abnormality which gave him two tails, from which he earned his nickname. Also, because of his unusually large IQ, Tails became a master engineer.

Tails Adventure
In Tails Adventure, prior to Sonic the Hedgehog 2, Tails had taken up residence on Cocoa Island in his own house with his own workshop. While living there, every day was pretty much the same for Tails.

One day, Tails was taking an enjoyable afternoon nap in the forest next to his house when he was suddenly awoken by the sound of explosions. Admits the chaos, Tails met a frantic Flicky who explained that the Battle Bird Armada, led by Great Battle Kukku 15th, had invaded Cocoa Island and were now uprooting it in search for the Chaos Emeralds that were located on the island at that time, so their leader could use them for world domination. While Tails was dumbfound and confused about what was happening, he soon after saw Great Battle Kukku 15th leading his battalion through the burning forest, making Tails realize the threat was real. Seeing that he was the only one who could save Cocoa Island, Tails mustered all his courage and set out to liberate the island.

From there, Tails traveled across Cocoa Island, liberating it from the Battle Bird Armada and recovered the Chaos Emeralds. Along the way, Tails gained an enemy in Speedy. When Tails later infiltrated the Battle Bird Armada's undersea stronghold, the Battle Fortress, he was trapped by Dr. Fukurokov, but Tails managed to outwit the doctor and escaped the Battle Fortress as it rose into the sky. Tails soon after invaded the Battle Fortress in his Sea Fox, where he defeated Speedy and afterwards Great Battle Kukku 15th for good. Returning to the Sea Fox, Tails escaped the Battle Fortress as it crashed into the sea. Having saved the island, Tails returned to his workshop where he build a larger model of his Remote Robot, only to have it explode in his face.

Sonic the Hedgehog 2
In Sonic the Hedgehog 2, Tails had taken up residence on West Side Island where he was bullied by the native animals for his two tails. One day while walking around alone and sad, however, Tails was taken by surprise when Sonic the Hedgehog ran past him. Seeing Sonic run like the wind made Tails greatly admire him for how cool he was, and he had a change of heart. He then resolve to become as cool as Sonic and began following him around. However, Tails was too shy to show himself to Sonic and hid in the tress' shadows whenever Sonic tried to see him for them to continue following him. Though Sonic ignored him, Tails still followed him and eventually earned his attention by keeping up with his speed. As such, Sonic allowed Tails to tag along.

During an early afternoon, Tails discovered Sonic's biplane, the Tornado, on the beach. Fascinated by the craft, Tails began investigating it, but then shyly pulled back when he saw Sonic napping under its wing. As he then went to investigate the Tornado's other side, however, an explosion erupted from the woods, forcing Tails to seek shelter under the Tornado before he was blown away. There, he saw the destruction of the island and Badniks digging in the ground. As the explosions continued, Tails discovered Sonic standing by him before the hedgehog ran into the attack, while Tails reflectively followed him.

Arriving in the inferno, Tails and Sonic discovered it was Sonic's arch-enemy, Dr. Robotnik, who was behind this. The doctor had arrived on West Side Island where he turned the animals into Badniks to find the Chaos Emeralds, which were currently on the island, so he could create the Death Egg to conquer the world. Tails and Sonic then teamed up to find the Chaos Emeralds first and save the island.

Traveling across West Side Island, the duo got the Chaos Emeralds first. Along the way, Tails proved a great assist to Sonic and the two build a strong bond. After freeing West Side Island, Tails and Sonic followed the doctor to the Wing Fortress Zone in the Tornado, with Tails piloting it. When they got there, Tails was shot down in the Tornado. However, he returned in time with a rocket engine-enhanced Tornado to help Sonic catch Robotnik in his rocket ship. Tails then got Sonic to Robotnik's rocket so he could ride it to the Death Egg while Tails remained behind.

Back on the ground, Tails watched the Death Egg explode thanks to Sonic. He then took the Tornado back into the sky to look for Sonic. There, he saved Sonic from his fall from space and the two of them flew through the sky together. At the end of their adventure, Tails and Sonic had become best friends, and Tails became his idol's sidekick.

Sonic Chaos
In Sonic Chaos, Tails was with Sonic on another adventure when they heard troubling rumors about Dr. Robotnik seeking the Chaos Emeralds on South Island. After quickly returning to South Island, the duo found the place in utter chaos and learned that Robotnik had stolen one of the Chaos Emeralds, thereby creating an imbalance that scattered the rest of the Chaos Emeralds across South Island, which was now sinking into the ocean. Banding together, Tails and Sonic headed out to recover the Chaos Emeralds and save South Island.

As they traveled across the island, Tails and Sonic successfully collected the lost Chaos Emeralds before confronting Robotnik. After defeating the doctor for good and driving him off, Tails and Sonic got the final Chaos Emerald in Robotnik's possession back, securing South Island's safety.

Sonic the Hedgehog 3
In Sonic the Hedgehog 3, many days after the events of Sonic the Hedgehog 2, Tails had just finished developing his newest invention, the Jewel Radar, when his device picked up a signal of Chaos Energy out at sea. Thinking it could have something to do with the big tidal wave he saw a few days earlier, Tails thought it could mean trouble and left to consult with Sonic. After telling the hedgehog about his discovery, Tails and Sonic prepared themselves and left in the Tornado to investigate the source of the Chaos Energy as their next big adventure.

When they arrived at the location of the signal, Tails and Sonic found the legendary floating isle Angel Island. Instead of the island being stationed in the sky, however, it was floating in the sea. To their surprise, Tails and Sonic saw it was due to the Death Egg, which they thought had been destroyed, having crash-landed on Angel Island and forced it into the sea. Seeing that the Death Egg was currently being rebuilt, Tails came with Sonic to stop Dr. Robotnik from relaunching the Death Egg and using it to conquer the world.

As Tails brought the Tornado close to Angel Island, Sonic went ahead and transformed into Super Sonic with the Chaos Emeralds and got to the island first. When Tails arrived there, however, he got there only to see Knuckles the Echidna, the guardian of Angel Island and its treasure, the Master Emerald, ambush and revert Sonic. Knuckles, having being tricked by Dr. Robotnik into thinking Tails and Sonic wanted to steal the Master Emerald, then stole the Chaos Emeralds and escaped with them to hide them, forcing Tails and Sonic to search the island for the Emeralds.

After this unfriendly arrival, Tails and Sonic continued onward, traveling across Angel Island to freed it from Robotnik's control and destroy the Death Egg for good. Along the way, Tails and Sonic were repeatedly ambushed by Knuckles, but the duo survived each encounter. On their travel, they also recovered the Chaos Emeralds. Eventually, Tails and Sonic made it to the Launch Base Zone, where they got onboard the Death Egg just as it took off. There, Tails and Sonic met Robotnik, who had come to smite Sonic with excessive force. Sonic defeated Robotnik in the ensuring fight however, with their battle taking its toll on the Death Egg at a critical point of its launch, which made it crash into the Lava Reef Zone.

Sonic & Knuckles
In Sonic & Knuckles, as the Death Egg fell from the sky, Tails and Sonic escaped the space station, with Tails carrying Sonic safely to the Mushroom Hill Zone. After landing, however, Tails and Sonic discovered that the Death Egg had survived plummeting into Angel Island's volcano, so they set out to explore the island so they could find the Death Egg and destroy it for good, and as well discover Robotnik's fate.

While about to pass through Mushroom Hill Zone, Tails and Sonic saw Knuckles coming through a hidden doorway in a thicket. Once they were sure Knuckles was gone, Tails and Sonic took a look inside the room hidden by the doorway, where they found a Giant Ring that took them to the Emerald Shrine in the Hidden Palace Zone, the location of the Master Emerald. There, Tails and Sonic learned of the connection between the Chaos Emeralds and the Master Emerald when the Master Emerald caused the Chaos Emeralds to be pulled away from Sonic and returned to the pedestals around them. After that, Tails and Sonic returned to Mushroom Hill to continue their search.

Following another journey across Angel Island, Tails and Sonic made it to the Hidden Palace Zone on their own, where Sonic had a showdown with Knuckles and won. Tails and Sonic then followed Knuckles when he went to check the Master Emerald. When Tails, Sonic and Knuckles got to the gem's resting place, however, Robotnik had arrived and was stealing the Master Emerald so he could use it to power the Death Egg, making Knuckles realize he had been duped by Robotnik. As Robotnik escaped with the Master Emerald, Tails and Sonic were guided by Knuckles to a hidden Warp Point to the Sky Sanctuary Zone, from where the trio witnessed the successful re-launch of the Death Egg. Because Knuckles was too exhausted from the previous struggles, however, Tails and Sonic had to leave him behind while they went after Robotnik. As they made their way through the sanctuary, Tails and Sonic came under attack by the Eggrobo and Mecha Sonic, which they fought several times. When they destroyed Mecha Sonic during their third encounter, the resulting explosion made a tall pillar nearby crumble, but Tails and Sonic managed to get on the Death Egg just in time by running along the pillar as it was crumbling to pieces.

Onboard the Death Egg, Sonic and Tails encountered Dr. Robotnik for the final showdown, where the doctor attacked them with the Kyodai Eggman Robo, powered by the Master Emerald. However, Sonic and Tails still defeat the contraption which resulted in the Death Egg's complete destruction. While Sonic then gave chase to Robotnik in space as the doctor escaped with the Master Emerald, Tails returned to Earth to get the Tornado. Taking the bi-plane back into the sky, Tails caught Super Sonic/Hyper Sonic on the Tornado when he returned from space with the Master Emerald after defeating Robotnik. The two of them then toiled the Master Emerald back to Angel Island where it belonged, thus allowing Angel Island to return to the sky. Tails and Sonic then made peace with Knuckles before leaving Angel Island themselves.

Sonic the Hedgehog Triple Trouble
In Sonic the Hedgehog Triple Trouble, Dr. Robotnik had n malfunctioning weapons test involving the Chaos Emeralds that dispersed the Emeralds across the planet. Once Tails and Sonic heard about this incident, the two of them entered the action to find the Chaos Emeralds before Robotnik could recover them. As they ran around to collect information on the Chaos Emeralds, however, Tails and Sonic met Knuckles when he suddenly popped out and blocked their path. Knuckles, having been tricked by Robotnik into thinking they wanted the Chaos Emeralds for the wrong reasons, then told them that they would never get the Emeralds before leaving. Amidst Tails and Sonic's confusion, an additional threat came into play when the dangerous treasure hunter Fang the Sniper set his sights on stealing the Chaos Emeralds for profit.

Despite faced with troubles on three fronts, Tails and Sonic pressed onward and recovered all but one of the Chaos Emeralds while confronting the nuisances from Fang and Knuckles' respective traps and ambushes along the way. When they got to Dr. Robotnik's base, Tails and Sonic faced Metal Sonic and following Fang. When they defeated Fang, however, Robotnik entered the frenzy with his newest machine, scaring Fang off.

At the end of the battle, Tails and Sonic defeated Robotnik and took back the last Chaos Emerald in the doctor's possession. Tails and Sonic then found Knuckles imprisoned and freed him, and the duo made peace with Knuckles again before talking off on the Tornado to find new adventures.

Tails' Skypatrol
In Tails' Skypatrol, Tails left Sonic for the time being and went on a solo-travel, flying around looking for an adventure of his own. He eventually discovered a small island and landed there to investigate, but found it to be seemingly uninhabited and had mine cart tracks weaving all around. As Tails began to fret that Dr. Robotnik was behind some sort of operation on the island, he sensed danger when he felt the vibrations of an approaching cart on the tracks and went into hiding in the grass. There, he saw an old witch arrive, proclaiming herself as Witchcart to herself before claiming the island as her own while threatening to turn those that opposed her into crystal. As Witchcart then left with her henchmen, Tails left his hiding place, firm with determination, and headed out to save the island from Witchart.

Giving chase to Witchcart, Tails journeyed across the island while taking out Witchcart's henchmen Carrotia, Bearenger, and Focke-Wulf one by one. He eventually caught up to Witchcart and faced her in battle where he emerged victorious. With Witchcart and her henchmen defeated and the island safe, Tails left again, joyous about his victory.

Sonic the Fighters
In Sonic the Fighters, Dr. Robotnik had constructed the Death Egg II from where he planned to take over the world. However, Tails discovered the Death Egg II from surveillance videos and created the Lunar Fox to reach the Death Egg II and destroy it. However, the vessel had only one seat and it needed all the Chaos Emeralds' power to take off. As such, Tails and Sonic entered a fighting tournament where the winner got to collect all the Chaos Emeralds, which was in the possession of all the participants, Tails included, and as well earn the right to use the Lunar Fox to destroy the Death Egg II.

At the end of the tournament, the victor got all the Chaos Emeralds and used them to go to the Death Egg II in the Lunar Fox. There, the victor defeated both Metal Sonic and Robotnik using the Emeralds and rigged the Death Egg II to self-destruct before heading back to earth in the Lunar Fox moments before the massive space station exploded.

Sonic 3D Blast
In Sonic 3D Blast, Tails was traveling to Flicky Island with Sonic and Knuckles. Due to hearing legends about how the island's native Flickies held the key to finding the Chaos Emeralds, Tails and his friends journeyed there, thinking the Flickies could help them find the Emeralds. When they got to the island, however, the trio was shocked to find the island in a pandemonium. Tails and the others soon after learned that this chaos was caused by Dr. Robotnik who had arrived on the island before-handed and established a base there from where he turned the Flickies into Badniks and used them to search for the Chaos Emeralds, which were on the island. Tails and his friends thus decided to stop Robotnik by liberating the Flickies from their prisons, bring them back to their home dimension and find the Chaos Emeralds before the doctor.

Following that, Tails and Knuckles assisted in Sonic finding the Chaos Emeralds by taking him to their locations, while Sonic saved the Flickies. Thanks to Tails and Knuckles' help, Sonic succeeded in thwarting Robotnik's plans and restoring peace to the island.

Sonic R
In Sonic R, Tails was with Sonic on another casual adventure, where they saw a large electronic billboard advertising the World Grand Prix, a racing competition to determine the fastest in the world. Enthusiastically, Tails suggested to Sonic that he should enter the World Grand Prix, before thinking about entering it was well to test his skills against others. At first, Sonic had no interest in entering, but when he saw Dr. Eggman on the list of participants he quickly took of to register, leaving Tails to chase after him.

When entering the World Grand Prix, Tails competed with not only Sonic, but also Knuckles, Amy and Dr. Robotnik and his robot minions, who were using Tails and his friends to locate the Chaos Emeralds which were located on the race tracks. As the end of the World Grand Prix, Tails and the others secured the Chaos Emeralds before Dr. Robotnik, thus preventing the doctor's plans once more.

Sonic Adventure
In Sonic Adventure, when Sonic left on a journey, Tails devoted himself to tinkering in his workshop. During one of his test flights, he found a Chaos Emerald and decided to use it to power his latest aircraft: the Tornado 2. One day, Tails performed a flight test with the Tornado 2 prototype, but in the midst of the test, he experienced engine troubles and crashed in Emerald Coast.

As Tails recovered, he met Sonic who saw him crash. The two returned to Station Square where Tails explained about his project and his Chaos Emerald before going to his workshop with Sonic to show his work. There, however, they met Dr. Eggman who demanded Tails' Chaos Emerald for his latest scheme, but Tails refused, provoking Eggman to attack in the Egg Hornet. Despite beating the Egg Hornet, the doctor snatched the Chaos Emerald from Tails. Eggman then revealed Chaos and transformed it into Chaos 1 with the Emerald. While Tails was frighten by Chaos, Dr. Eggman revealed his plan to make Chaos invincible with all seven Chaos Emeralds and use it to build Robotnikland upon Station Square before leaving. Figuring that Chaos could not transform without more Chaos Emeralds, Tails left with Sonic to find the rest.

Not long after, Tails and Sonic found two Chaos Emeralds in Windy Valley and Casinopolis respectively. When they left Casinopolis, however, they were ambushed by Dr. Eggman with sleeping gas and took one of their Chaos Emeralds. Unshaken, Tails and Sonic continued looking for the Emeralds and found one in Ice Cap. No sooner, they were attacked by Knuckles, who Eggman had duped into believing they had stolen parts of the Master Emerald. Knuckles vaguely demanded their Emeralds, but they refused. In the ensuring battle with Knuckles, Tails and Sonic lost their Chaos Emeralds, which were taken Dr. Eggman who had just arrived. Eggman then gave the Emeralds to Chaos 2, turning it into Chaos 4, but Tails and his friends beat it. As Eggman escaped in the Egg Carrier, Tails and Sonic followed him in the Tornado, but in the insuring aerial fight, the Tornado was shot down.

Tails landed in Mystic Ruins where he was briefly knocked out and had a dream of his first meeting with Sonic. Tails then figured that to get the Egg Carrier, he need the Tornado 2 and set out to find a Chaos Emerald for it. When he found one, however, Froggy appeared and took it, forcing Tails to chase him. When he caught Froggy, Tails met a mysterious light that took him into the past where he met Tikal. Back in the present with Froggy in hand, he had an brief awkward meeting with Big the Cat who had been looking for Froggy. As Big then chased Froggy when he escaped, Tails had gotten the Chaos Emerald back and used it to finish the Tornado 2 which he then used to look for Sonic.

While flying, Tails found the Egg Carrier and Sonic at Red Mountain. Reunited with Sonic, the duo got onboard the Egg Carrier with the Tornado 2 and set out to find Amy who had been kidnapped by Dr. Eggman. When they found Amy on the bridge, they saw Dr. Eggman take a Chaos Emerald from Amy's Flicky before they were attack by E-102 Gamma. After Amy kept Sonic from destroying Gamma, the Egg Carrier began to lose altitude and Tails flew Amy to safety upon Sonic's orders.

Bringing Amy to Station Square, Tails saw Dr. Eggman crash nearby and went to check it out. There, he saw Eggman firing a missile in a last attempt to destroy Station Square, only for the missile to turn out to be a dud. When Eggman left to rearm the missile, Tails saw only he could save Station Square and wished Sonic was there, but then realized he could not depend on Sonic forever and that he could do this himself. Filled with courage, Tails got to the missile and disarmed it. When Eggman got there, the doctor attacked Tails in his Egg Walker, but Tails defeated Eggman and received cheers from Station Square's citizens. Soon after, Tails met up with Sonic again.

Following that, Tails left to find the Tornado 2, but learned Angel Island had fallen. Bringing the news to Sonic, they headed to Angel Island where they found both Knuckles and Eggman knocked out and learned from them that Chaos was still alive, had rebelled, and now had six Chaos Emeralds. Sonic and Tails then got ready the find the last Chaos Emerald before Chaos, though they were slowed down when Sonic was briefly send to the past by Tikal. When they found the last Chaos Emerald however, Chaos took it before their eyes. Tails then traveled to Station Square which was attacked by Perfect Chaos. There, he found one of the drained Chaos Emeralds and brought to Sonic while his other friends brought the remaining six, telling him that he could still use their positive Chaos Energy to defeat Chaos. Tails then saw Sonic transform into Super Sonic and defeat Perfect Chaos, neutralizing its evil. Tails then saw Chaos depart with Tikal and noted how all had ended well, but then noticed Sonic had already left for his next adventure.

Sonic Shuffle
In Sonic Shuffle, Tails was with Sonic, Knuckles and Amy when the three of them were pulled into Maginaryworld. Arriving in the Temple of Light, Tails and the others met Lumina Flowlight, the one responsible for bringing them to Maginaryworld. Lumina told them about Maginaryworld before explaining that she had brought them here to help her restore the Perfect Precioustone which had been shattered by Void. Its pieces had then been scattered and their guardian and protector of the Precioustone, Illumina, had vanish as well. If the pieces remained lost, Void would destroy Maginaryworld. Without hesitation, Tails agreed to help along the others.

Tails began their adventure by recovering the Precioustone pieces from the different worlds within Maginaryworld, and restoring the places affected by Void. Whenever they got a Precioustone, Tails and his friends had a dream where he met Void. In these dreams, Tails and the others initially opposed Void, but they soon saw that Void was lonely and depressed which touched their hearts, and they eventually realized that Void and Lumina embodied the positive and negative aspects of dreams and were two halves of the same being.

After gathering the lost Precioustones and bring them back to the Temple of Light, Tails and his friends was forced to head there as well when Void went for the Perfect Precioustone. When they got there, Void told them he only wished to be whole, but was unable to become it. In the face of Tails and the groups' opposition, Void’s sadness reached its peak and he became a monster, but Tails, Sonic, Knuckles and Amy defeated him.

Despite their victory, Lumina despaired as the Perfect Precioustone did not recovered despite Tails telling her that she and Illumina had touched them. When Sonic found Void in the form of a dark gem, the group tried to make Lumina accept Void, with Tails telling her that negative feelings were necessary for dreams since that whenever he felt down, he was always motivated to try harder for his dreams. Having cheered up Lumina, Tails and the others then saw Lumina restoring the Perfect Precioustone, and Lumina and Void merging back into their original form, Illumina. As Marginaryworld was restored to an even better place, Tails and the gang received Illumina's gratitude before they returned home.

Sonic Adventure 2
In Sonic Adventure 2, Tails was rewarded with a Chaos Emerald from Station Square for saving the city from the missile attack in Sonic Adventure. One day, while watching TV, Tails caught the news broadcast saying that Sonic had been arrested for robbing a federal reserve bank. Refusing to believe that Sonic would commit such a crime, Tails took off in his Cyclone and headed for Prison Island where Sonic was imprisoned, intending to free him. When he got there, he found Amy being cased by Dr. Eggman, so Tails came to Amy's aid and fought Eggman until he left. Hearing from Amy that she had come to free Sonic too, Tails teamed up with her and the two successfully infiltrated Prison Island and freed Sonic. When Prison Island then began to explode, Tails, Sonic and Amy got off the island in the last moment.

Traveling to Central City, Tails, Sonic and Amy saw Eggman's broadcast, where he revealed the Space Colony ARK and displayed the Eclipse Cannon, powered by six Chaos Emeralds, by blowing up half of the Moon, before demanding total world control within 24 hours or he would fire the cannon at earth. Tails figured he could use his Chaos Emerald to locate Eggman due to the Emeralds' magnetic relationship, but then the police arrived. However, Sonic distracted the police, allowing Tails to work. However, Tails was unable to get a signal (causing him to speculate that the Emeralds were in outer space), and instead found a transcript in the President's limousine which they could use to find Eggman. Contacting Sonic on his findings, the two of them met up in the President's limo, where Tails located Eggman on the Space Colony ARK.

With Knuckles' help, Tails, Sonic and Amy found Eggman's base where they hoped to find a space ship that could take them to the ARK so they could destroy the Eclipse Cannon. When they reached the center of the base, however, the group was ambushed by Eggman and his Egg Golem. While Sonic defeated the Egg Golem, Tails and the others prepared a space shuttle for them to take off in.

While en route to Space Colony ARK, Knuckles tried to take control of the shuttle when a stray asteroid made him lose his Emerald Shards, causing Tails and the others to crash land on the ARK. Once onboard, Tails came up with a plan of action; by giving Sonic a fake Chaos Emerald he had made, Tails planned to have Sonic insert it into the Eclipse Cannon when he himself shut off the power, thereby destroying the Eclipse Cannon from the inside out. After destroying the ARK's generator, however, Tails learned that Amy was held captive by Eggman and was threatened to be killed unless they gave him their Chaos Emerald.

Meeting up with Sonic at Eggman's location, Tails and Sonic planned to have Eggman take their fake Chaos Emerald. Eggman, however, saw through this when Tails accidentally revealed the Emerald was fake. As Sonic was then trapped in a capsule and rejected into space, Tails was entrusted by Sonic to finish the fight. When Sonic's capsule then exploded, Tails fought Eggman with renewed determination to fulfill Sonic's wish and defeated the doctor. After the confrontation, Tails was relieved when Sonic revealed he had survived by contacting him (though his excitement distracted him from preventing Eggman from taking his Chaos Emerald) and watched Sonic destroy the Eclipse Cannon.

As Tails met everyone in the ARK's control room, the Space Colony ARK had begun a collision course with earth. Tails and all the others then saw a recording of Gerald Robotnik announcing to the world that the ARK would crash into the planet and destroy it as his revenge at the world for the death of his granddaughter, Maria. Banding together with Eggman, Tails and the group came up with plan of using the Master Emerald to deactivate the cannon's core, which was powered by the seven Chaos Emeralds, to stop the Space Colony's crash course. Using a shortcut, Tails got Sonic and Knuckles to the core, but after they deactivated the Chaos Emeralds, the Biolizard merged with the ARK, becoming the Finalhazard and kept the ARK on its collision course. As Super Sonic and Super Shadow then fought the Finalhazard, Tails gave advice through transmission lines.

After Super Sonic and Super Shadow defeated the Finalhazard and brought the Space Colony ARK back into orbit, Tails and the others found Sonic returning alone, informing them that Shadow had seemingly died in the fight. Tails then talked with Eggman about Gerald, where Tails acknowledged their team-work before they returned to earth.

Sonic Advance
In Sonic Advance, Tails joined forces with Sonic, Knuckles and Amy to stop Dr. Eggman from obtaining the seven Chaos Emeralds. Over the course of their adventure, Tails and the others got the Chaos Emeralds first and chased the doctor to the X-Zone. After they defeated the EGG X, Tails, Knuckles and Amy returned to earth while Super Sonic faced Eggman in a final confrontation on the moon. There, they awaited Sonic's return, but grew confused when he did not show up. A few days later, Tails was searching for Sonic in the Tornado when he found Super Sonic flying though the sky, and Tails welcomed him back.

Sonic Advance 2
In Sonic Advance 2, Tails was kidnapped alongside Knuckles by Dr. Eggman when the evil scientist attempted once more to create the Eggman Empire. Fortunately, Tails was freed from Dr. Eggman by Sonic at Music Plant. Tails thanked Sonic for the rescue, but as Sonic tried to take off, Tails joined him in the fight against Eggman.

After freeing Knuckles and hunting down and seemingly beating Eggman, Tails, Sonic, Knuckles, Cream and Cheese found Vanilla who had gone missing, only to see her being kidnapped by Eggman in his new mech. Tails then witnessed Sonic using the Chaos Emeralds to become Super Sonic and taking off to rescue Vanilla and stop Eggman. When Sonic returned with Vanilla, Tails was thanked by Sonic for his help. However, Tails soon after noticed that Sonic had left on his own again.

Sonic Advance 3
In Sonic Advance 3, Tails was hanging out with Sonic when they saw Dr. Eggman splitting the Earth into seven regions with Chaos Control and planned to turn each region into a part of the Eggman Empire. Tails and Sonic then set out together to fix the planet and get the Chaos Emeralds before Eggman.

During their adventure, Sonic and Tails met Knuckles, Amy and Cream who joined them. Along the way, Sonic also faced Dr. Eggman's newest creation, Gemerl, a rebuilt version of Emerl. Eventually, Tails and his friends made it to the Emerald Altar where they beat the Hyper EggRobo and used the Master Emerald to return the world to normal. Later, Tails and the others found Sonic after his battle with Ultimate Emerl and welcomed him back before following him out on new adventures. When Gemerl's remains were later discovered by Cream and her mother, Tails rebuild the robot and restored his former friendly personality.

Sonic Heroes
In Sonic Heroes, Tails and Knuckles got a letter from Dr. Eggman, which said Eggman had created "the ultimate weapon" and challenged them to stop him within three days or he would conquer the world. Using the Tornado 2, Tails and Knuckles found Sonic and showed him the letter. Though Tails was disturbed about this and unsure what would happen, he and Knuckles joined Sonic as he set out to stop Eggman, thus forming Team Sonic.

Team Sonic began their mission by locating Eggman in Ocean Palace. There, they were attacked by Eggman in the Egg Hawk, but Tails and his team defeated the machine, though Eggman escaped. They then followed Eggman to Grand Metropolis, which Tails and his friends freed from Eggman's control. After coming out of the Power Plant, however, Team Sonic met Team Rose who began fighting them until they slipped away.

As the team arrived in Casino Park with only 24 hours left, Tails pressed his team onward. While passing through the city, Tails and his team were attacked by Eggman's robot horde which they defeated. After chasing Eggman to Rail Canyon and only having until sunset, Tails and his team headed for Bullet Station where they destroyed Eggman's base. There, they found Eggman in the Egg Albatross and defeated him. After the battle, however, Team Sonic discovered that the Eggman they had been chasing was a copy, and that their challenge was to distract them while Eggman launched his Egg Fleet. As they were about to chase after Eggman again, Tails grew suspicious when he noticed that the Eggman copy was not one of Eggman's robots.

Team Sonic continued to follow Eggman into the jungle where they met Team Dark. Though Tails was shocked to see that Shadow was alive, the teams quickly began to fight over who got to chase after Eggman. After that, Team Sonic followed Eggman and Shadow to Hang Castle, where Tails was spooked out by the surroundings and Knuckles' teasing. After infiltrating the castle and escaping Mystic Mansion, Team Sonic was attacked by Eggman's robot horde, but defeated it.

Soon after, Team Sonic got to the Egg Fleet and arrived at the Final Fortress where they destroyed the colossal flagship's core. Team Sonic then met Eggman in his Egg Emperor and defeated him. After destroying much of the Egg Fleet, Tails flustered received Sonic's thanks for his help before seeing Sonic escape from the newly arrived Amy.

Later, Team Sonic and the other teams saw the return of Metal Sonic, who had been staging the team's adventures and impersonating Eggman so he could follow them and copy their data in a plan to conquer the world himself, as he transformed into Metal Madness. Seeing that the teams had collected all the Chaos Emeralds, the real Dr. Eggman came up with the plan of using them against Metal Sonic. When Sonic decided to face Metal Sonic alone, Tails decided to go with him, along with Knuckles. While Team Sonic charged the Chaos Emeralds, Team Rose, Dark and Chaotix fought Metal Madness to buy them some time.

When Metal Madness transformed into Metal Overlord, Tails and Knuckles got a Super Shield from Sonic as he transformed into Super Sonic. The team then took off and defeated Metal Overlord. Back on the flagship, Tails joined Sonic as he left, and they soon after reunited with Knuckles. Together, the trio then headed out to find their next adventure.

Shadow the Hedgehog
In Shadow the Hedgehog, Tails assisted his friends and G.U.N. in defeating the scourge of the Black Arms who had begun to invade earth and as well battle Dr. Eggman. He appears during Shadow's Hero Missions where he asks Shadow for assistance.

Circus Park
During the Black Arms invasion, Tails arrived at Dr. Eggman's Circus Park in his Chaos Emerald-powered Tornado III, planning to take back the Rings Eggman had stolen to build this theme park. Shortly after arriving, however, Tails' plane was shot, causing him to crash-land. After surviving the crash, Tails met Shadow and asked for his help in recovering the Rings.

In the Hero scenario, where Shadow accepted Tails' request, the two of them successfully reclaimed all the stolen Rings. They also found Tails' lost Chaos Emerald which Shadow took.

Air Fleet
When the Black Arms went after the President onboard the Air Fleet, Tails got onboard the vessel in an attempt to save the President. There, he came across Shadow and he asked the black hedgehog for assistance in taking down the Black Arms.

In the Hero scenario, where Shadow agreed to help, Tails and Shadow managed to rid the Air Fleet of the invading Black Arms, thus saving the President. After that, they found one of the Chaos Emeralds.

Last Story
In the last story, Tails came to stop Shadow from giving the Chaos Emeralds to Black Doom with Sonic, Knuckles, Amy, Rouge and Dr. Eggman. Black Doom however, took the Emeralds and used an enhanced Chaos Control to transport the Black Comet to the surface, planning to use humans as energy sources for the Black Arms. Soon after, Tails and his allies were paralyzed by a special nerve gas and Black Doom unleashed the Death leeches on them. Shadow however, was immune to the gas and left Tails and the others behind as he pursued Black Doom.

Tails and the others eventually got out of the Black Comet and found some shelter from where they supported Super Shadow on as he defeated Devil Doom. Tails then saw Super Shadow sending the Black Comet back into space and destroying it with the Eclipse Cannon. With the invasion over, Tails joined the others for a laugh as an enraged Knuckles chased Eggman around.

Sonic Battle
In Sonic Battle, Tails saw Sonic having a brief fight with Shadow. When Tails got there, Sonic showed him a robot called the Gizoid he had found and asked him to take a look at it while he interrogated Rouge. Taking the Gizoid to his lab, Tails discovered it evolved with each Chaos Emerald inserted into it and that it could copy fighting moves, before his computer crashed from data overload. Meanwhile, Tails heard the news saying similar robots robbing jewel stores, much to his worry. When Sonic returned, Tails told him everything he had learned, and they decided to train the Gizoid.

After some training, Tails and Sonic decided to see if Knuckles had a Chaos Emerald to help the Gizoid, who Sonic named "Emerl", evolve. On the way, they met an E-121 Phi and Chaos Gamma, but defeated both. When they arrived at Knuckles’, however, Knuckles mistook Emerl for an E-121 Phi and attacked him. After Emerl beat Knuckles, Tails and Sonic explained everything and got Knuckles' Chaos Emerald which they gave to Emerl.

Later on, Tails grew worried about Emerl's behavior and decided to take him to a full examination in the lab in Central City since his own computer was down. After convincing Sonic to let him go with Emerl alone, Tails and Emerl got to the labs, only to be denied access by security. Soon after, Tails met Rouge who offered to help them get into the labs, but Tails was suspicious about her motives. Regardless, Tails and Emerl received a pass from Rogue after fighting her and got into the Central Lab. There, Tails discovered that Emerl was an ancient weapon of mass destruction bound to go out of control. Just then, however, Tails and Emerl were then attacked by Guard Robos for accessing restricted information.

After defeating the rbots, Tails and Emerl tried to escape, but were then attacked by Shadow, who wanted Emerl destroyed. Tails, however, would not let Shadow do it and fought him until Rouge arrived and took Shadow with her. Escaping to Holy Summit, Tails met up with Knuckles and told him to come with them to hear about Emerl. However, they were then forced to fight Chaos Gamma who blocked their way. Eventually, Knuckles held Chaos Gamma back alone, allowing Tails and Emerl to escape. Reunited with Sonic, with Rouge soon after joining them, Tails told him about Emerl's true nature and that he could not reprogram Emerl as he was too advanced. However, Rouge revealed that they could reset Emerl by inserting all seven Chaos Emeralds into him and giving him an unknown keyword. As Rouge left, Tails attempted in vain to stop a fight between Sonic, Emerl and Knuckles when Knuckles arrived.

Sometime later, Tails was practising with Emerl and Sonic when Amy arrived, scaring Sonic off. Tails told Amy about Emerl, but accidentally made Amy think Sonic was practising with Emerl to raise a child with Amy. Too scared to tell Amy otherwise, Tails left to find Sonic, but When he returned, Amy told him Emerl was kidnapped by Rouge and he left to inform Sonic. Later, Tails and Knuckles aided Sonic when he fought Rouge to get Emerl back, with Rouge eventually surrendering Emerl.

A while later, Tails was alone with Emerl when Knuckles came to train Emerl. However, when they heard the news saying an E-121 Phi had appeared Knuckles and Emerl went to deal with it. When they returned, they gave Tails some Emerald Shards and Tails figured out he could make a whole Chaos Emerald of they brought two more shards. Knuckles and Emerl soon came back with more shards and Tails assembled a whole Chaos Emerald which he gave to Emerl.

Later, Tails met Amy who tricked him into telling where Sonic was. Soon after, Amy and Emerl came with five Emerald Shards and Tails assembled a full Chaos Emerald from them which they gave to Emerl. Later, Tails and Sonic left Emerl in Amy's and Cream’s care, while they checked a lead on a Chaos Emerald, which turned out to be false. A while later, after Emerl had been reset of his destructive programming by Shadow, Tails met Emerl again, who had come to fight him, and was defeated.

Later, Tails saw Dr. Eggman reveal his newest Death Egg and its Final Egg Blaster. Meeting up with Sonic and Emerl about the news, Tails feared it was a trap, but nevertheless prepared a teleporter to take them to the Death Egg, though it could only take one of the time. As Emerl was chosen to stop Eggman, Tails send Emerl off to the Death Egg and watched him fight Eggman through a monitor. When Eggman was defeated, however, Eggman destroyed some start with the Final Egg Blaster, causing Emerl to revert to his original programming. However, Eggman could not control Emerl as excepted, and Emerl prepared to fire the Final Egg Blaster at earth. Tails then send Sonic to the Death Egg with the Master Emerald to neutralize Emerl's power, but then that failed, Tails came up with a painful alternative solution: destroying Emerl. Once Emerl was destroyed, the world was saved, though Tails mourned Emerl's death and wondered if they would see him again.

Sonic Rush
In Sonic Rush, Tails met Sonic who revealed that Dr. Eggman was up to a new scheme involving "the ultimate power" and that a mysterious girl named Blaze the Cat had appeared. As such, Tails headed with Sonic to stop Eggman.

At Water Palace, Tails and Sonic met a new foe named Dr. Eggman Nega who had teamed up with Dr. Eggman. After Sonic beat Eggman Nega, Tails grew suspicious at this turn of events and headed to his workshop with Sonic to check something. There, Tails discovered to his horror that there was a rift in the space-time continuum that threatened reality itself, which he thought Eggman Nega was behind though Sonic suspected Blaze was part of it too. As they continued fighting Nega and searching for info, Tails and Sonic visited Vanilla who revealed Cream was with Blaze and where they could find them. Tails and Sonic therefore left to find Blaze and get some answers.

While on their way, Tails and Sonic ended up on path blocked by a rock pile which Knuckles emerged from. Knuckles then told Tails and Sonic that he got trapped under the rocks when casing Blaze before smashing the rocks in anger. With the path cleared, Sonic and Tails continued onward and eventually found Blaze and Cream. Tails tried to ask Blaze about the space-time rift, but Blaze insisted she would deal with the crisis and Eggman Nega alone and ran off with Cream, promoting Tails and Sonic to follow them. Along the way, Tails and Sonic met Amy, who told them where Blaze went, though Tails had to ask on Sonic's behalf since Amy almost thought Sonic liked Blaze.

After that, Tails and Sonic following Blaze to Dead Line where Blaze was convinced to let them help her. Blaze then revealed that the space-time rift was caused by her world and Tails’ world merging with one another due to the Sol Emeralds having been stolen and brought to Tails' world. After Blaze told that Eggman and Eggman Nega were behind this, Tails and Sonic got ready to confront Eggman Nega on Blaze's behalf since she was unable to fight, when they noticed Cream was gone. They then found a letter from by Dr. Eggman saying he held Cream hostage and that Blaze had to come to Point W alone. As Blaze left to save Cream alone since she was her friend, Tails was skeptical about this, but was assured when Sonic insisted they should believe in her. After Sonic and Blaze defeated the Eggmans, Tails congratulated Sonic and celebrated their victory until Amy arrived and droved Sonic off.

A while afterwards, Tails came to Blaze's aid with Sonic, Knuckles, Amy and Cream when Eggman and Eggman Nega drained all her Sol Emeralds of their power to conquer both Tails' dimension and the Sol Dimension. There, Tails and his friends gave Blaze their moral support, allowing Blaze to recharge the Sol Emeralds and become Burning Blaze. She then joined together with Super Sonic and defeated the Eggmans, saving both dimensions.

Sonic Rush Adventure
In Sonic Rush Adventure, Tails discovered an unknown energy reaction and went to investigate it with Sonic in the Tornado. When they reached it however, they entered a storm and were sucked into a hurricane. Tails and Sonic then washed ashore on Southern Island where they met Marine the Raccoon. Finding themselves in unknown territory, Tails and Sonic decided to explore this sea. The next day, they witnessed Marine destroy her own vessel by accident. With notes provided by Marine though, Tails build the Wave Cyclone which the trio used to explore the nearby islands.

While traveling, Tails and the others were attacked by several robotic foes, Johnny included. After Tails made the Ocean Tornado and they reached Coral Cave, the group met Captain Whisker and his crew, who were the ones behind the robot attacks. To Tails and his friends' surprise, they also met Blaze the Cat when she suddenly appeared, who helped beat Whisker's Ghost Kraken. After the battle, the pirates escaped with the Jeweled Scepter, an artifact hidden in Coral Cave which Blaze tried to protect. As Tails and Sonic wondered why Blaze was not in her world, Tails realized that he and Sonic had been transported to Blaze’s world during the storm. Once they explained their story to Blaze, Tails and Sonic feared that the pirates posed a threat to both their worlds with the scepter and suggested to Blaze that they should team up, which Blaze accepted.

Following their alliance, Tails and his friends searched the sea for the pirates' whereabouts. Along the way, Tails made more vessels for them to use in the different waters. After having tracked and lost the pirates at Haunted Ship, freeing the Vikings on Blizzard Peaks from the pirates' captivity, and uncovering the secrets of Sky Babylon, the group found the pirates’ hideout in some ancient ruins. As they prepared to head there however, Tails, Sonic and Blaze decided to have Marine stay behind as she could endanger the mission. Though Tails and Sonic tried to be gentle, they silently agreed with Blaze when she told Marine she was a nuisance, making her run off crying.

Arriving at the ruins, Tails and his friends cornered Whisker, only for the pirate to escape. They then saw Marine coming and going after the pirates, but got caught by the Ghost Titan, making Tails, Sonic and Blaze take off to rescue her. When they reached the pirates, Tails distracted Whisker by saying the Jeweled Scepter was elsewhere, allowing them to save Marine. Once the Ghost Titan was destroyed, Tails and his friends escaped the pirates' ship as it sank with the pirates. Once Marine showed she got the Jeweled Scepter back however, the group returned to Southern Island.

After collecting all the Chaos Emeralds and Sol Emeralds, Tails and Sonic prepared to go home when they heard that the Jeweled Scepter had been stolen again. In the wake of an earthquake, the thieves revealed themselves to be Dr. Eggman and Dr. Eggman Nega in the Egg Wizard, who were behind the pirates, so they could use the Jeweled Scepter's ability to harness the Power of the Stars to build Eggmanland upon both worlds. Fortunately, Tails had prepared the Magma Hurricane, allowing them to chase the doctors to Deep Core where Super Sonic, Burning Blaze and Marine defeated the doctors.

The next morning, Tails build the SS Tornado EX for him and Sonic to return home in. As they were taking off, Marine arrived in her new vessel to say goodbye. Tails and Sonic then promised Marine they would see each other again before returning to their own world.

Sonic Riders
In Sonic Riders, Tails came to Future City with Team Sonic to find a Chaos Emerald. There, they see the Babylon Rogues and Tails saw on his radar that they had the Chaos Emerald. They then chased after the Babylon Rogues, where Tails glimpsed the symbol on Storm's Type-S and realized who the thieves were. He and Knuckles soon after caught up to Sonic when he chased after Jet and found him knocked down while the Babylon Rogues escaped.

The next day, Tails and his team saw Dr. Eggman on some monitors, announcing the EX World Grand Prix and that the entry fee for the contestants was a Chaos Emerald, with the winner getting all seven. When they saw the participants Eggman had found were the Babylon Rogues, Team Sonic entered the competition.

After Tails and his friends passed the qualification rounds, they met Amy, who had also signed up for the tournament. Tails, having pondered about the symbol he saw, then told the others the legends he knew about the Babylon Rogues, Babylon Garden and the Treasure of Babylon. As Tails then tried to tell Knuckles about Extreme Gear, Wave the Swallow came by and mocked Tails' customized Blue Star (and secretly planted a bomb on it), infuriating Tails. No sooner though, Tails and the group left for the next race.

After making it to the semifinals, Tails and Knuckles watched Sonic practice with Extreme Gear until Jet appeared and mocked Sonic before taking his leave. This made Tails doubt the Blue Star he made for Sonic, though he resolved to unlock the Extreme Gears' secrets. In the following race, Tails beat Wave and got her out of the competition. Eventually, Tails and his team made it to the finals, which Jet won after Wave sabotaged Sonic's Blue Star.

With the competition over, Tails and his friends watched Jet claim and use the seven Chaos Emeralds in tandem with the Key to Babylon Garden to reveal Babylon Garden itself, with the intention of claiming its treasure. Eggman, however, stole the key so that he could claim the treasure himself, believing it to be technology that he could use to conquer the world. Tails and Knuckles then quickly followed Sonic as they took off to stop Eggman.

When Team Sonic approached Babylon Garden in the Tornado 2, Tails gave Sonic the Blue Star II, which he made for such an occasion, so Sonic could pursue Eggman. On Babylon Garden, Tails and Knuckles met Wave and Storm, but before blows could be exchanged, Tails got them to leave when he saw a flock of E-10000s coming. Tails and Knuckles then followed Wave and Storm to Sonic, where Sonic had stopped Eggman and returned the Key to Babylon Garden to the Rogues. Tails and his friends then got ready to leave until Amy showed up and chased Sonic around for attacking Eggman while he held her hostage. No sooner, Tails and the others heard a roar from inside Babylon Garden and went to investigate. There, the group saw the Babylon Rogues had awoken the Babylon Guardian, which they were forced to fight.

After beating the Babylon Guardian, Team Sonic and the Babylon Rogues found the Treasure of Babylon, which was a Magic Carpet, much to Eggman's disappointment. After observing the carpet however, Tails and Wave saw it was an ancient prototype of Extreme Gear. With the adventure over, Tails and his friends left the Babylon Rogues until the would meet again.

Sonic Riders: Zero Gravity
In Sonic Riders: Zero Gravity, a few months after the EX World Grand Prix, Tails was awoken from his sleep when a small meteorite impacted outside. The next morning, Tails brought the meteor to Sonic and Knuckles and drove them to Megalo Station in Monopole. Suddenly, however, they were attacked by SCR-HD and a group of SCR-GP, a part of a currently global robot rampage who were after the meteorite. As they tried to escape, Team Sonic fell out from a 300-story building, though Tails and Knuckles saved themselves by flying while Sonic was saved by the meteorite which could manipulate gravity.

As they tried to hide from the robots, Tails and the group met Amy, who was a target of the robots too because she had a meteorite similar to theirs. The group then decided to go to MeteorTech, who created the robots, to get answers. When they got there, Tails and his friends were discovered by security, only for the Babylon Rogues to appear and Jet repelling the security robots with another meteorite. While Tails was surprised to see the Rogues, Jet demanded their meteorites, called the Ark of the Cosmos, but Tails got his team to leave when more robots showed up.

Arriving in the control room, the group were surprised to find Dr. Eggman, who owned of MeteoTech, though Eggman claimed to have no part in the global robot rampage. Under persuasion, Eggman revealed MeteoTech’s mother computer was powered by an Ark of the Cosmos and that the robot's leader, SCR-HD, which also had an Ark of the Cosmos, sought them out for reasons unknown. However, everyone then realized Amy was gone and saw she was being chased by SCR-HD and Storm on the computer screen, so Tails left with his team to save her.

When Tails and the others found Amy, they saw SCR-HD had suddenly blown up and Storm had taken its Ark of the Cosmos. While Knuckles thought this would end the robot rampage, Tails figured it would only stop when they removed the Ark of the Cosmos in MeteoTech’s mother computer. As they tried to figure where the mother computer could be, Amy remembered Storm mentioning Gigan Rocks, which held information about the Ark of the Cosmos. Tails and the others therefore went to Gigan Rocks to investigate.

When they came to Gigan Rocks, Tails figured out from the ruins that the Arks of the Cosmos were power units for Babylon Garden. The group then saw the Babylon Rogues chase after Eggman above them, and learned from both that and the ruins the location of MeteoTech’s mother computer. Arriving at this location, the group found the Crimson Tower and met the Babylon Rogues, who told them Eggman had stolen their Arks of the Cosmos. Tails understood that Eggman planned to use them to control all the world's robots, which they realized was the doctor's next plan for world conquest, and both groups raced each other to Eggman.

When they reached Eggman, the doctor was stopped and the robot rampage ended. Following Babylon Garden appearance due to all Arks of the Cosmos being present, Tails and his team left the Arks of the Cosmos to the Babylon Rogues and almost left when Tails realized the Babylonians hid the Arks of the Cosmos to prevent the creation of a black hole. Just then, SCR-HD appeared and took all Arks of the Cosmos to Babylon Garden, transforming it into Astral Babylon and creating a black hole that could destroy the planet. Tails. Knuckles and the Babylon Rogues then followed Sonic to Astral Babylon to disconnect the engine where they met and beat Master Core: ABIS, saving the world.

With the adventure over, Tails returned to Monopole with his friends where he explained why the Arks of the Cosmos made the robots run amok. Tails and then others then saw Jet flying by, who challenged Sonic to a new race, which Sonic accepted.

Sonic Free Riders
In Sonic Free Riders, Tails, Sonic and Knuckles signed up to compete in the second World Grand Prix hosted by Dr. Eggman for the sake of the competition rather than the prizes. As they were interviewed by Omochao though, Tails thought that the races seemed fishy.

To begin with, Team Heroes first opponents were Team Rose where Tails thought it would be a good race while his other teammates thought otherwise. As Amy berated at Sonic for not going easy, Tails defended Sonic by saying that he never holds back and that he thought that Amy liked this trait. Nevertheless, Team Heroes was victorious, with Tails commenting that it was a very easy victory.

Tails and his teammates were then up against Team Dark in their second race. During the race, Knuckles suspected that Team Dark's new member, E-10000B was cheating, but Tails did not witness anything to support Knuckles' claim.

After Tails and his teammates beat Team Dark and got to the finals where they were up against Team Babylon. Between their races, Tails praised Wave's Extreme Gear, but Wave interpreted it as sarcasm though Tails did not intend it. When it seemed like Team Heroes had beaten Team Babylon, it turned out Team Babylon had technical trouble and Tails offered to help take a look at their Gear, but Wave pushed him away. After Sonic then beat Jet in a rematch and secured Team Heroes' victory, Tails and his teammates were commended as the champions and Tails commented to the viewers that he felt more confident working with Extreme Gear now.

As the tournament progressed, Team Heroes had their own losses too, though Tails was still intent to improve his skills. After the tournament was over, Tails and the other teams went to the awards ceremony to collect their prizes but Eggman made all of the competitors race his "ultimate Gear-jockey robot". After the race, Eggman revealed that he used the World Grand Prix to gather the riders' racing data with his E-10000 robots to create the ultimate Extreme Gear which he could use for his own agenda, which made Tails realize Knuckles was right about E-10000B. Eggman then raced Tails and the others but lost, and Tails mocked Eggman. However, they all then saw Metal Sonic emerge from E-10000B and Tails realized Metal Sonic took the data for himself and passed fake info to Eggman, all to beat Sonic on Extreme Gear. Tails then watched Sonic raced against Metal Sonic with the others.

After Sonic beat Metal Sonic and Eggman cursed being tricked, Tails had figured out Eggman never had any prize to give and pointed it out, which disappointed many of the competitors, before he and the others left as the World Grand Prix drew to a close.

Sonic the Hedgehog (2006)
In the Sonic the Hedgehog (2006), Tails met Sonic in Soleanna. Having heard Sonic tried to protect Princess Elise from Dr. Eggman, Tails offered to help Sonic in his mission to rescue Elise from Eggman. The duo eventually found the Egg Carrier at Wave Ocean and tried to catch it, but failed.

Back in the city, Tails and Sonic learned Eggman was in Dusty Desert. Arriving at Eggman's base, Tails and Sonic found Elise, but then Eggman appeared and ordered his Egg Cerberus to attack them. After defeating the Egg Cerberus, Tails created a diversion that caught Eggman's forces' attention, allowing Sonic to escape with Elise. Some time afterwards, Tails heard from Knuckles that he wanted to see Sonic and asked Tails to bring him. After Tails had brought Sonic, they saw Knuckles had a message from Eggman who demanded that Sonic gave the Chaos Emerald he had in exchange for Elise (whom he kidnapped again).

Though Tails suspected it was a double-cross, he, Sonic and Knuckles went to the doctor's base in White Acropolis, where Sonic gave the Chaos Emerald to Eggman. At that moment, however, Eggman trapped Tails, Sonic and Knuckles in his time machine and sent them to an apocalyptic future. There, the group met Shadow and Rouge and the five of them joined forces to find enough Chaos Emeralds for a Chaos Control powerful enough to get them back to their own present.

While searching for the Chaos Emeralds, Tails, Sonic and Knuckles briefly saw Silver and Blaze talking with Mephiles before they went back in time. As Tails searched their database, the group learned that Elise would die in the Egg Carrier's future crash-landing. After locating a Chaos Emerald in Flame Core, Team Sonic regrouped with Rouge and Shadow, and ventured into the volcano, but had to face Iblis when they found the Chaos Emerald. After Iblis was defeated, Sonic and Shadow use their two Chaos Emeralds to create a time-space rift which Tails, Sonic and Knuckles used to go back to their original timeline.

Back in the present, Tails helped find information on Elise's present whereabouts. Later, when Elise was forced to return to Eggman after having just been saved, Tails went to help Elise upon request from a Maid in Waiting, but did not make it in time. Soon after, Tails helped Sonic through Aquatic Base to save Elise from her death on the Egg Carrier.

Later, Tails was with Knuckles and Amy in Castle Town when they were caught in a spatial distortion created by Solaris and send to End of the World where they met Shadow, Silver, Rouge, E-123 Omega and Eggman. There, they all found Sonic and Elise, where Tails saw to his sorrow that Sonic was dead, having been killed by Mephiles to remake Solaris. As Solaris prepared to end all of time, however, Elise sensed that Sonic's soul was still among them, so Tails and the others collected all the Chaos Emeralds to revive Sonic and save the world. After witnessing Elise revive Sonic as Super Sonic, Tails supported him, Super Shadow and Super Silver as they defeated Solaris before the were engulfed in light. When Sonic and Elise then ensured Solaris never came to exist, time was reverted, resulting in the events and memories of the adventure being erased and Tails to be returned to where he was prior to the events.

Sonic Rivals
In Sonic Rivals, Tails came with Sonic to Onyx Island, which had appeared at sea, to investigate it, believing it was one of Dr. Eggman's evil plots. Just as they arrived, Tails and Sonic found who they thought was Dr. Eggman, but was actually Dr. Eggman Nega in disguise (Tails however, does not realize this throughout the game). Upon meeting him, Eggman Nega showed them a card depicting Amy Rose and explained he had turned Amy into this card with a special camera. Tails tried to explain it was possible for objects to be turned into cards when Sonic doubted Eggman Nega's claim, but was then turned into a card by the doctor. Tails' card was then taken by Eggman Nega, setting Sonic off to save Tails from the doctor.

Eventually, Sonic got Tails' card back after he beat Eggman Nega's Egg Lynx and Tails was restored to normal. Later, Tails came to Sonic and Knuckles' aid in his new Tornado plane when Eggman Nega escaped, and brought them to the doctor's space base. After Sonic and his allies had foiled Eggman Nega's plans to turn the Earth into a card, Tails and Sonic got Amy back to normal as well. No sooner though, Tails left with Sonic to find the other captives in Eggman Nega’s cards.

Sonic Rivals 2
In Sonic Rivals 2, Tails discovered some Chao had gone missing on an island and suspected Dr. Eggman was behind it since he was on the island too. Tails then called Sonic to him and told him everything, and they teamed up to find Eggman and get answers. Shortly after, Tails and Sonic met Rogue and Knuckles, where Rouge asked of Eggman's whereabouts. Once Tails told her that and what he and Sonic were doing though, Tails had to chase after Rogue and convince her not to tell Eggman that they were after him when seeing him.

The group eventually found Dr. Eggman, who really was Dr. Eggman Nega disguised as Dr. Eggman (Tails does not realize this throughout the game), but the doctor played innocent about taking the Chao. After beating Eggman Nega's Egg Liner, Tails and Sonic followed the doctor to Sunset Forest Zone where they lost the trail. However, Tails found a lost page of Eggman Nega's describing a creature named the Ifrit. While alone, Tails noticed Espio was following him. Tails told Espio what he and Sonic was doing, but when he refused to say more and Espio insisted they did not get involved in this, Tails had to race and battle Espio to get away.

Soon after, Tails and Sonic, along with Espio and Silver, found Eggman Nega and had to fight his Egg Crawler. After that, Tails and Sonic followed the doctor to Neon Palace Zone where Tails found more pages on the Ifrit. They also bumped into Shadow and Metal Sonic, where Tails began to follow Metal Sonic on Sonic's order, thinking trouble was up. When he caught Metal Sonic though, Tails was forced to fight him briefly. Afterwards, Tails, Sonic, Shadow and Metal Sonic found Eggman Nega again where they had to defeat his Egg Dealer.

As Tails and Sonic tracked Eggman Nega to Frontier Canyon Zone, Tails found another one of the doctor's lost pages on the Ifrit. They also found Knuckles and Rouge again, who needed Rings to fuel their Emerald Detector, and Tails and Sonic agreed to help find some for them. Once Tails had gotten enough Rings, however, Silver came and took them, making Tails chase after him. Soon after, Tails and Sonic found Eggman Nega and fought his Egg Bull against Silver and Espio. After beating Eggman Nega, the doctor revealed he planned to release the Ifrit from a portal within Mystic Haunt Zone, making Tails and Sonic head there to stop the Ifrit.

Inside the mysterious mansion, Sonic and Tails split up to cover more ground. While searching, Tails was forced to face a shape-shifting ghost, but defeated it. Following that, Tails reunited with Sonic and the duo found Eggman Nega with their ghost counterparts. The two of them then faced the doctor in his Egg Phantom and beat it. After that, Tails found the missing Chao, who Eggman Nega planned to feed to the Ifrit to make it invincible, and brought them to a safe place.

With the Chao safe, Tails and Sonic found the slowly closing portal to the Chaotic Inferno Zone, the dimension of the Ifrit, and they went in there to find Eggman Nega. Inside this dimension, Tails and Sonic found the Ifrit, who took control of Sonic's soul, leaving Tails with no choice but to fight both the Ifrit and Sonic to save the world. Though Tails occasionally fell prey to the Ifrit too, he and Sonic beat it and secured it would be left trapped in its dimension. As Tails and Sonic got back to their dimension just before the portal closed, Tails came with Sonic to the Chao Garden to rest up from saving the world.

Sonic Chronicles: The Dark Brotherhood
In the beginning of Sonic Chronicles: The Dark Brotherhood, Tails, along with Sonic, Knuckles and Amy, faced Dr. Eggman on the Egg Carrier. With Tails damaging the ship, the team made the Egg Carrier crash into Metropolis which seemingly resulted in Eggman's death.

After Sonic went on a solo vacation, Tails spend his time alone, working on machines, helping Knuckles protect the Chaos Emeralds and committed small-time heroics, which made him grow as a person. Some time later, Knuckles asked Tails to help catch a group dubbed the Marauders who had stolen six of the Chaos Emeralds. Tails helped Knuckles by making a trap where Knuckles used the last Chaos Emerald as bait, but when the Marauders came, they jammed the trap, took the Chaos Emerald and kidnapped Knuckles. Tails therefore called Sonic back from his vacation and brought his friends together to find Knuckles.

With G.U.N.'s help and Tails' wit, the team found the Maurauders' hideout and Knuckles. After rescuing Knuckles, they were going to Angel Island to protect the Master Emerald from the Marauders when they discovered that Angel Island was gone. Suspecting Eggman was working with Marauders, the team decided to find the doctor. With Tails' technical skills, the team found Eggman. However, the doctor claimed that he was also against the Marauders and that he had been reformed, willing to help Tails and the others fight the Marauders by leading them into Metropolis where the Marauders had drawn Angel Island to with the Chaos Emeralds, which the team accepted.

On their way, Tails and the team met Shade and discovered that she and the Marauders were a group of echidnas from the Nocturnus Clan, exiled to the Twilight Cage over four millennia ago. Though Tails and his team beat Shade and her lackeys, Shade blocked the way to Metropolis, but Tails and the others found a way around. In Metropolis, Tails stayed behind to work on a non-lethal weapon against the Nocturnus Clan with Eggman and some their friends while Sonic, Knuckles and their team went Angel Island. After help the other team on their way, Tails, Eggman and their team soon got to Angel Island with their weapon and dispatched the echidna soldiers attacking Sonic and Knuckles.

With the soldiers out of the way, Tails and the others joined Sonic in fighting Imperator Ix, the mastermind behind the Nocturnus Clan who sought to rule the world, but were unable to stop Ix from stealing the Master Emerald. Ix then used the Master Emerald to create a wormhole into Sonic’s dimension so the Nocturnus Clan could conquer it, and Angel Island fell from the sky. Having survived the crash, Tails and Eggman had the idea of building a rocket so they could go after Ix into the Twilight Cage and reclaim the stolen Emeralds. Shade also joined them, having realized her leader's evil nature.

With the others' help, Tails and Eggman build the Blue Cyclone to enter the Twilight Cage, though Eggman stayed behind. Inside the Twilight Cage, Tails and his team got five of the Chaos Emeralds back and forged alliances with the alien races in the Twilight Cage. When they prepared to infiltrate Nocturne to find the last Emeralds, the group got help from the different alien races. Once they arrived on Nocturne, the group split into two teams, with Tails and Sonic leading their group and Knuckles and Shade leading the other, to find the last two Emeralds kept by Charyb and Scylla.

On their way, Tails and Sonic helped Knuckles' group defeat some Gizoid Centurions. They then found Charyb and beat him with the help of Knuckles and his team, and reclaim the Chaos Emerald. Once Knuckles got their Chaos Emerald as well, Tails and his team went to Ix’s throne room where they saw Knuckles standing by his duties despite Ix's persuasions and attacked him. Soon after, Tails and the others stepped in and stalled Ix while Knuckles got the Master Emerald back. After Ix was defeated, Ix started to close the wormhole out of the Twilight Cage, but Tails and the others got through it just in time. When they returned home however, Tails and the others saw that much time had passed, thus allowing Eggman to rebuild his forces, which they faced upon exit from the Twilight Cage.

Sonic Unleashed
In Sonic Unleashed, when the Earth was broken in several pieces, Tails went to Apotos to gather data, hoping that adding this data to the research findings of his friend Professor Pickle should shred some light on this global crisis. At nightfall, Tails was attacked by a flock of Dark Gaia's Minions, but was saved by Sonic the Werehog. Recognizing Sonic despite his new form, Tails met up with him and his new friend Chip, and heard Sonic's story about his recent scuffle with Eggman which created his werehog form and shattered the Earth. Tails then took Sonic and Chip with him to Spagonia in his Tornado-1 so they find Professor Pickle and get his help, but when they arrived they learned Eggman had kidnapped the professor.

Tails, Sonic and Chip tracked Pickle to Mazuri where they freed him from his prison in Eggman's base and reclaimed the stolen Gaia Manuscripts. Afterwards, they learned from Pickle that an ancient creature named Dark Gaia was behind the world's shattering, but it was not fully reborn. With this window of opportunity, Professor Pickle told Tails and Sonic that they could restore the world and the currently powerless Chaos Emeralds by placing the Emeralds in the Gaia Temples across the world.

From there, Tails assisted Sonic and Chip in restoring the planet by taking them to where the Gaia Temples were located so they could restore a continent and a Chaos Emerald. When there was but one continent left to fix, Tails took Sonic and Chip to Eggmanland where the last Gaia Temple was. There, Tails kept his position where he monitored the continent's restoration and reported back to Pickle until the Tornado-1 was attacked. After the planet had been restored and Dark Gaia was defeated, Tails reunited with Sonic at Windmill Isle and followed him out on his next adventure.

Episode I
In Sonic the Hedgehog 4: Episode I, which takes place shortly after the events of Sonic & Knuckles, Tails took his leave from Sonic when the hedgehog went on a break alone. However, when Dr. Eggman returned to rid himself of Sonic with a new army of improved Badniks, Tails secretly supported Sonic during his adventure. When Eggman later escaped to E.G.G. Station Zone, Tails provided Sonic with a rocket he had made to let him follow Eggman.

Episode II
In Sonic the Hedgehog 4: Episode II, a few months after Sonic the Hedgehog 4: Episode I, Tails came with Sonic to investigate Dr. Eggman newest scheme on the neighboring continent. Arriving in Sylvania Castle Zone in the Tornado, the duo began investigating. They soon found Eggman and learned the doctor planned to turn Little Planet, which had made its annual return, into a power source for his Death Egg mk.II. As such, the duo chased after Eggman to stop him. During their chase, Tails and Sonic were attack by Metal Sonic, who had returned stronger than ever and had teamed up with Eggman to stop them. In each fight though, the duo beat the robot double.

When they chased Eggman to the Sky Fortress Zone, Tails and Sonic used an escape pod to follow Eggman and Metal Sonic to the Death Egg mk.II before the Sky Fortress exploded. On the space station, they fought Eggman and Metal Sonic until the villains escaped. They soon after met Metal Sonic who wanted a rematch with Sonic, but Tails and Sonic defeated him. The duo then faced Dr. Eggman and his Egg Heart and defeated him, but also made the Death Egg mk.II crash. Tails and Sonic therefore used two escape pods to return home while watching the Death Egg mk.II shut down and be pulled away by Little Planet's orbit.

Sonic Colors
In Sonic Colors, Tails came with Sonic to Dr. Eggman's Incredible Interstellar Amusement Park, an amusement park made of planets, before its opening day to investigate. Tails, however, remained skeptical about Sonic's theory that the park was one of Dr. Eggman's evil plans. When they got there, they met a white alien and Tails began reconfiguring his Miles Electric into a translator to comprehend the alien's language while Sonic investigated. When Tails had the translator ready (albeit with a few bugs), he and Sonic learned from the alien, named Yacker, that Eggman was capturing his race, named the Wisp, and that he asked the duo to save them

Agreeing to Yacker's request, Tails and Sonic began exploring the surrounding planet. When Sonic had destroyed a generator, Tails learned from Yacker that Eggman was harvesting the Wisps' Hyper-go-on, and brought the news to Sonic. While exploring another planet, Tails saved Sonic from Eggman's Mind Control Ray, but ended up mind-controlled. Before he could fight Sonic on Eggman's orders though, the machine ran dry and Tails was freed. While Sonic's kept Eggman's robot busy, Tails learned from Yacker that Eggman was using the generators to keep the Wisps' planets captive while he kidnapped them. Relaying this info to Sonic, the duo set out to destroy the remaining generators, believing this would stop Eggman's plans.

The duo continued their journey across Eggman's amusement park, with Tails providing valuable info to Sonic. After the generators had been destroyed and the Wisps freed, Tails and Sonic returned to the Tropical Resort where they began celebrating their victory with the Wisps. However, when the amusement park began to collapse due to Eggman's mind control cannon backfiring when the doctor tried to use it, Tails and Sonic escaped to Eggman's space elevator to go home, but was met by Eggman in the Nega-Wisp Armor who wanted Sonic destroyed. As Tails feared they could not beat this robot, he was pushed into the elevator by Sonic for safety and send back to Earth. Back home, Tails was reunited with Sonic when the Wisps brought him back from his battle with Eggman. After the Wisps had quelled the black hole created from the mind control cannon, Tails and Sonic met Yacker again who thanked them for helping, but now had to leave. Though saddened, Tails understood and said farewell to Yacker and watched the Wisps leave with the kidnapped planets.

Sonic Generations
In Sonic Generations, some time after Sonic Colors, Tails attended and helped prepare Sonic's surprise birthday party. After Sonic arrived, Tails gave Sonic a birthday Chili dog when the Time Eater appeared and sucked Tails into one of its Time Holes. Tails then ended up in the White Space, where he was turned into a statue due to the Time Eater's effects.

Tails was soon returned to normal thanks to Sonic and they teamed up to find the rest of their friends taken by the Time Eater. While Sonic was gone though, Tails briefly met Sonic's past self, Classic Sonic, but believed him to be the present Sonic (named Modern Sonic). While Modern and Classic Sonic passed through a Boss Gate, Tails met his past self, named Classic Tails, as well. Once the Sonics returned, both Modern and Classic Tails had figured out they were all traveling through time and space.

With the Time Eater at large, the Tails' and Sonics teamed up to stop it. While the Sonics worked on restoring their friends and areas, Classic and Modern Tails got them intel on how the Time Eater was ripping space apart, that the Sonics speed was the key to restoring space and time and finally, the Chaos Emeralds were the Time Eater's weakness, which they set their sights on collecting. When the Tails' and Classic Sonic came to see Dr. Eggman defeated by Modern Sonic in the Egg Dragoon, they saw Eggman being taken by the Time Eater, which confused them since the Sonics said the Time Eater already had kidnapped him.

After getting the Chaos Emeralds and freeing their friends, the Tails' followed the Sonics to the domain of the Time Eater for the final showdown. There, Dr. Eggman and his past self, Classic Eggman, revealed themselves as the ones behind the Time Eater in an attempt to erase Sonic from history so that the doctors would be victorious in the present. When the Sonics were knocked out the Time Eater, however, the Tails' and their friends cheered them on, allowing them both to transform into Super Sonic. When the Sonics defeated the Time Eater, the Tails' and their friends were sent back to the present and their party. Once the time came for Classic Tails and Classic Sonic to return their time during the party, Classic and Modern Tails said their goodbyes to each other as they went their separate ways.

Sonic Lost World
In Sonic Lost World, Tails and Sonic were pursuing Dr. Eggman, Orbot and Cubot in the Tornado to free some animals they had captured. When Eggman dropped the Capsule with the captive animals, Tails and Sonic went after it, but the Tornado's wing was shot by Eggman's laser gun. As they fell, Tails and Sonic stumbled upon the Lost Hex. Landing on the Lost Hex, Tails began repairing the Tornado while Sonic investigated the area. Once Tails was done, he and Sonic took off to find Eggman and his newest (enslaved) allies, the Deadly Six.

Arriving in Desert Ruins, Tails and Sonic found Eggman scolding the Deadly Six. Despite Tails warning Sonic not to touch the conch Eggman used to control the Deadly Six with after examining it, Sonic recklessly knocked the conch away, causing the Deadly Six to rebel against Eggman by talking control of his Badniks and having them attack everyone. In the skirmish, Tails was injured, but he was taken to safety by Sonic as they escaped with Eggman and his lackeys.

Escaping to Tropical Coast, Tails and Sonic departed from Eggman, Cubot and Orbot to handle the Deadly Six. In the meantime, he and Sonic were contacted by Amy, who informed them that something was sucking the life out of the world. Soon after, they met Eggman again, who revealed that the Deadly Six were using his Extractor to destroy the Earth, which they saw matched Amy's report. The two factions then decided to team to stop the Deadly Six by bringing Eggman to the Extractor and have him shut it down properly.

While traveling, tensions rose between Tails and Sonic, as Tails was angry at Sonic for seemingly trusting Eggman more than him to stop the Extractor. Some time later, Tails and the group were briefly contacted by Zavok, who stated the futility of their actions, but they still continued on. In the meantime, Tails tried to repair Cubot after the Deadly Six's attack, but was attacked by Cubot when he put his head on a Crabmeat. Unexpectedly, Tails was saved by Eggman, but he was still scolded by Sonic for endangering himself.

Later on, the team stumbled upon a Capsule. However, Tails discovered it was a trap set by the Deadly Six and he saved Sonic from it when he tried to open it, though at the cost of being caught in it himself and teleported to the Deadly Six, who had planned to capture Sonic instead and make him their slave. While in their captivity, Tails was nearly turned into a robotic weapon against Sonic by Zavok, but Tails used one of his twin tails to reprogram the machine for the conversion process. Disguising himself as a cyborg, Tails tricked the Deadly Six into thinking he was their slave. When he was send to kill Sonic, Tails attacked Zavok, Zeena and Zor by surprise, allowing Sonic to finish them.

With the Deadly Six defeated, Tails and Sonic went to shut down the Extractor when they discovered it was already turned off. Eggman then showed up in a new mech, having earlier faked his death so that he could charge his mech while Sonic fought the Deadly Six, and planned conquer the remains of the world. After Sonic defeated Eggman, Tails reprogrammed the Extractor to return the Earth's energy while accepting Sonic's apology for doubting him, mending their friendship. With Eggman incapacitated from falling from the Lost Hex, Tails and Sonic returned to Amy and Knuckles on Earth, where Tails watched Sonic take a nap to rest from this ordeal.

Sonic the Hedgehog CD
In Sonic the Hedgehog CD, Tails was not initially a playable character in the game, having only been reduced to mild cameo appearances as a picture and in the Tornado during the game's sound test. The likely reason for this is because it entered development with Sonic the Hedgehog 2 around the same time, so the game's design did not consider Tails in the final release. When it was decided that Sonic the Hedgehog 4: Episode II would reference the events of Sonic the Hedgehog CD, Tails was added as a playable character in the 2011 re-release of Sonic CD to further connect to it. He goes through a similar progression as Sonic's story, except he does not encounter Amy Rose or have animated cutscenes. He can also freely fly, but does not have the Super Peel Out move. There is no gameplay mode in which Tails follows Sonic. Also, the player is unable to collect trophies/achievements while playing as Tails.

Sonic Drift Series
Tails is a playable character in the game Sonic Drift, where he races along fellow friends Sonic the Hedgehog and Amy Rose, and arch-enemy Dr. Eggman. In the game, Tails is racing in the Chaos Grand Prix and is the most balanced of the four racers. Tails' special ability is the ability to "Jump", literally flying his kart into the air for about three seconds, where he gains temporary "invincibility" to his surroundings and objects; he is also unaffected by terrain while doing this, so if the player has gone off the course, it's best to maneuver back over to the track.

Tails is also playable in the sequel Sonic Drift 2, where he is racing in the Second Chaos Grand Prix. Tails is once again the most balanced of all the racers. Tails' special ability is still the ability to "Jump", literally flying his kart into the air, but for about five seconds instead of three, like in the original.

Knuckles' Chaotix
Tails and Sonic appeared as cameo appearances in the Sega 32X game Knuckles' Chaotix, where they fly by in the Tornado during the good ending cutscene.

Sonic and Tails were originally playable in this game, or at least planned to be as the very first prototype or precursor for the concept of the game (Sonic Crackers). When the game was made to be Knuckles' Chaotix, early prototypes of the game featured Sonic and Tails as playable characters. Over time, Tails' data was coded into a sprite of a glitchy white Knuckles recolor dubbed Wechnia by fans. "Wechnia" was able to fly with the data of Tails, and eventually was changed to a more unique attack style but was deemed a failure and was never finished. Eventually, Sonic's data was created into Mighty the Armadillo, who performed near identical to how Sonic had and most simply put, was appearance wise a recolored clone of Sonic's sprites without spikes.

Mario & Sonic at the Olympic Games
In Mario & Sonic at the Olympic Games, Tails is one of the 16 playable characters (8 being from Sonic's universe) as a Skill-type character. He also appears in Mario and Sonic at the Olympic Winter Games as one of the now 20 playable characters (10 from the Sonic Universe with the addition of Metal Sonic and Silver) and has the highest jumping stats. He is still a Skill type character. Tails' signature moves for the game are Tailspin for the Wii version and Propeller Dash for the DS version. Tails is also playable in Mario and Sonic at the 2012 London Games, in this game he is, as usual, one of the faster Sonic characters. On the Official Olympic Games website all character descriptions depict what each character excels at. Tails' description depicts his high-Skill based abilities that will make him formidable in a wide range of events. It also states that his high acceleration and speed will make him tough to beat in many races.

Tails has missions in both DS version and Wii version of ''Mario & Sonic at the Olympic Games. DS Missions are:'' Wii version missions are:
 * Don't miss any shots in shooting
 * Don't make mistakes on your four performance command inputs in Vault
 * Earn GOOD rating 8 times in your performance at Trampoline
 * Hit the center of the target to score 10 points under strong wind conditions
 * Reach the goal without taking damage (hitting spike fences or getting hit by opponents items. Shield protects you from failing)
 * Beat Yoshi in Dream Canoe
 * Time your jumps to reach 7M high in Trampoline
 * Jump from the blue zone and clear the bar in High Jump
 * Throw the hammer from the center 3 times in Hammer Throw
 * Jump right after the foul line 2 times in Triple Jump
 * Finish in 2nd place in 4X100m relay
 * Shoot a 2 point circle in one attempt in Archery

Super Smash Bros.series
In Super Smash Bros. Brawl, he has a Green Hill Zone cameo. He reprises this role in Super Smash Bros. for Nintendo 3DS in the same stage. He also has an unlockable trophy, only obtainable by accumulating over 30,000 feet of walking distance between all characters.

Sonic & Sega All-Stars Racing
In Sonic & Sega All-Stars Racing, Tails appears as a playable character. In this game he created both his and Sonic's race cars, the Tornado Racer and the Speed Star. His All-Star move is Tails Tornado. This move creates a tornado that sucks up other racers and items that get in his way.

The Tornado Racer was built as a land based version of the Tornado capable of making fast turns with its short wing span. It was built with parts found after an attempted invasion by Dr. Eggman.

The Tornado Racer's engine output most likely was limited on purpose by Tails as if it were faster it would fly like a normal plane. The Tornado Racer has enough speed to hover over the ground, so its power was limited just enough, also if it gets launched off of a hill, it has a very slow descent suggesting its capabilities of flight. Also during Tails' Tornado, the Tornado Racer flies in the air with the tornado that the move creates.

Sonic & All-Stars Racing Transformed
In Sonic & All-Stars Racing Transformed, Tails is a Playable character. With the games new form of gameplay with transforming vehicles, Tails no longer rides the mini bi-plane Tornado Racer, he instead rides a Formula-1 race car that appears to be a modified version of his MTP-01 Whirlwind from Sonic Drift (a possible reference to said game). When going over land the Formula-1 racer remains in its normal state, when going across water it turns into a speedboat. Its flying form has wings that have fins that stick out on the top and bottom and a small, yet powerful jet engine and what appears to be a spoiler.

Sonic and the Secret Rings
In Sonic and the Secret Rings, Tails is a playable character in Party Mode, but during the main story he acts as a guide, with his likeness used for Ali Baba in place of Tails himself. Sonic mistakes him for the actual Tails, but Ali Baba does not know what he's talking about.

The Ali Baba that is represented in this story is exactly like Tails, in the fact that he knows how to fly using his two tails as shown in a cutscene. He also has a personality like Tails as they are very kind and enjoy helping their friends. Ali Baba also went on numerous adventures with Sonic along with Sinbad (Knuckles' counterpart) before Sonic was transported out of the book, this is exactly like the friendship of Sonic, Tails and Knuckles back at home. In Multiplayer, normal Tails is a playable character along with Sonic, Knuckles, Amy, Cream, Silver, Shadow and Blaze.

Sonic and the Black Knight
In Sonic and the Black Knight, he is portrayed as a blacksmith that Sonic goes to have Caliburn sharpened. He is playable in multiplayer mode. In multi-player mode he uses a slingshot as his weapon. He is amazed at Caliburn's details and the fact that Caliburn can talk. Once he resharpens Caliburn, Sonic is able to use his Soul Surge. Sonic can then return to him before missions to equip items, check his stats and forge new weapons for the other Knights of the Round Table.

Like Tails Arabian Nights counterpart Ali Baba, the Blacksmith counterpart is exactly like Tails, in the fact that he knows how to fly with his two tails as shown in Multiplayer Mode. He also has a personality like Tails as he enjoys helping his friends and is very kind. Unlike in Sonic and the Secret Rings, normal Tails is not playable in Multiplayer Mode, his Blacksmith counterpart is playable instead.

Other Appearances
It has been confirmed that in the unreleased Sonic X-treme, which was in development for the Sega Saturn platform, Tails would have appeared, playing in a first person flight mode. Sonic CD contains Tails in the form of a piece of artwork that features him standing next to a race car that has MILES on the license plate with the caption "SEE YOU NEXT GAME" above the car - a possible reference to Sonic Drift for the Game Gear, which was released the following year. He can also be spotted in the game's sound test, hovering around Little Planet in the Tornado. He was added as a playable character in the December 2011 re-release of Sonic CD, as well as the May 2013 re-release of the original Sonic the Hedgehog. In the latter, he can also follow Sonic around, despite the fact the two have canonically not met at this point. He is confirmed to appear in the upcoming Mario & Sonic at the Sochi 2014 Olympic Winter Games.

Personality
Tails is gentle, sweet-natured and loyal with a positive attitude. When young, he was initially timid and shy, but he has opened up and become more outgoing over the years. Tails is not one to grab the spotlight for himself and is instead always ready to willing help others without asking for anything in return.

Tails has a distinct love for mechanics and he finds himself most at home in his workshop working on his next creation. Despite his great skills, Tails is very humble about his abilities, never giving them many thoughts, though he has yet to discover his true potential of what he can accomplish. At the time of Sonic Lost World, Tails has become more outspoken about his intelligence, though he still does not openly brag.

When young, Tails often lacked self-confidence and courage. After meeting Sonic and gaining his support, Tails gained more confidence and belief in himself. However, this status quo, created from Sonic's authority over him put a mental stranglehold on Tails that made him dependent on Sonic. As such, he often lacked directions and confidence whenever he was on his own.

A turning point for Tails came in Sonic Adventure; when Station Square was in danger of being destroyed, Tails was the only one who could stop this. With Sonic nowhere to be found, Tails realized that he could not depend on Sonic forever and had to try on his own. After saving Station Square, Tails realized he could be independent and support himself without Sonic, and all he needed was determination and faith. Since then, Tails has become more independent, self-confident, motivated and brave, and can as well rise up to be a real hero when needed.

During their earlier adventures together, Tails strove to become just like Sonic by replicating the mannerisms he found admirable. In this period, Tails was content with being Sonic's sidekick as he was just happy to hang out with Sonic. As Tails grew as a person, he still remained as close to Sonic as ever as his sidekick and still looks up to him, but his esteem about Sonic's heroics have dwindled, as he these days cares more about inventing then Sonic's heroic deeds.

Despite his development, Tails still tends to depend on Sonic when he is in a moment of weakness. However, he hopes to one day be self-sufficient and independent like Sonic, while proving he can be relied upon. Also, even though Tails still enjoys being Sonic's sidekick, he believes that he can do almost anything if he puts his mind onto it.

Despite his intelligence and general fearlessness, Tails is afraid of lightning and can be naive and big mouthed, such as in Sonic Adventure 2 when he accidentally told Eggman that the Chaos Emerald that Sonic had was a fake, thus ruining the heroes' plans. Tails also hates feeling useless or being ignored, as seen in the cases when he is talking to Sonic. He also gets very angry when someone dismiss his mechanical skills and takes it very personally, as seen when Wave the Swallow mocked his self-customized Blue Star.

Tails has a tendency to talk techno-babble, much to the irritation of his friends, such as when he tried to explain how an Extreme Gear worked, meaning that Tails does not always use tact in a situational matter. Nevertheless, Tails is supportive of his friends, willing to be by their side no matter what or how dangerous the situation might be, and do whatever it takes to help them, even if it means sacrificing himself for them.

Twin Tails
Tails' unique trait is his genetic abnormality that has granted him two large, fluffy tails that can twirl together. During his lifetime, Tails has learned to use his two tails to his advantage in many situations, which is usually for transportation or unique combat moves.

The most noticeably skill Tails has demonstrated with his twin is his ability to achieve flight with them. By twirling his twin tails around like rotary blades, Tails is able to lift himself off the ground and fly around in mid-air like a helicopter. When in flight, Tails can move at incredible speeds, reaching that of 768 mph (1,236 km/h) and go fast enough to keep up with Sonic, with great agility and mobility. He can also use his twin tails to manipulate his descend through mid-air, allowing him to glide. He can also use his tails as a turbine to push himself forward while hovering slightly above ground, allowing him to reaching speeds nearing those of Sonic himself. Tails' outstanding speed in this field is partially due his training with Sonic.

There does appears to be a limit to Tails' endurance, concerning how long he can stay airborne with his twin tails; as shown in nearly all his game appearances, Tails can only fly with his twins tails for a limited time before he becomes exhausted from the effort and starts falling down.

Tails' twin tails are shown to be very powerful limbs in their own right, being both strong and fast enough to slice through metal. In combat, Tails can also use his twin tails for different fighting moves and techniques. His tails are also shown to be prehensile, as in Sonic Lost World where he grabs a toothpick from Zomom's sandwich with one of his tails and uses it to reprogram a machine that was going to turn him into a brainwashed robot.

Physical Abilities
Like many of the other characters in the Sonic the Hedgehog series, Tails is able to move at super speeds without the need of his twin tails to push himself even faster. Although not considered as fast as Sonic without using his twin tails, it is shown on several occasions that Tails is an exceptionally fast runner as well. In the ending of Sonic Heroes, he could keep up with Sonic by running and in Sonic Colors, when Tails was controlled by Eggman with his Mind Control Ray, he could move enough to block even Sonic's movements.

Tails is also quite physically strong. He is able to lift both Sonic and Knuckles into midair within hindering his own flying speed and he can move blocks that supposedly weights several tons.

Tails also possesses great acrobatic skills, agility and reflexes. He is capable of setting off and jumping accurately between stone pillars, grinding on rails, and performing different kinds of body movements and tricks while airborne.

Tails is quite good at swimming as well. By using his twin tails as rear propellers, Tails can move underwater at significant speeds and with great ease.

Tails is capable of harnessing Chaos Energy to empower himself, though he has only been seen during on rare occasions, such as in Sonic the Fighters and Sonic the Hedgehog 3 &amp; Knuckles.

Intelligence and Mechanical Skills
Despite his young age, Tails has a genius-level intellect and is a natural prodigy when it comes to mechanics, being an extremely capable inventor and skilled mechanic. In fact, Tails' skills in mechanics even rivals those of Dr. Eggman, who is one of the greatest minds on the planet, though he has yet to reach his full potential in this field. Over the years, Tails has been known to create more than a few mechanical items of his own which have proven useful over time. These creations includes his various technological advanced, and often transformable, Tornado series of airplanes, his various combat equipments, his Chaos Emerald locater, the Sea Fox, the Lunar Fox, and his multifunctional Miles Electric to name a few. When given a piece of technology, Tails only needs to take a few looks on it to determine its functions, elements and purposes, even for the highly advanced Gizoid androids. In Sonic Lost World, it is stated that Tails is smart enough to build a TV out of paperclips and reprogram a supercomputer using a toothpick and dishwashing detergent.

When it comes to new forms of construction, Tails is quick to grasp new technologies, such as Material technology, and once he develops an understanding of it, excels on the subject in question. In the fields of Extreme Gear mechanics, Tails has great skills at tuning and constructing different kinds of Extreme Gear. Though he is not as skilled in Extreme Gear mechanics as Wave the Swallow, his skills on the subject is great enough to impress Wave, which is a considerable feat given her standpoint for good Extreme Gear mechanics.

Tails is also quite brilliant in science and physics. When dealing with matters involving the fabric of time and space or other theoretical situations, Tails can quickly come up with solid theories to how certain events will occur. In line with his mechanical skills, Tails can even construct vessels that can travel between dimensions or withstand trans-dimensional interference. As seen in Sonic Colors, Tails can also read and translate Binary and Hexadecimal language. He also have some knowledge about ancient legends, such as the one about the Babylonians.

Tails seems to know more about the Chaos Emeralds than most characters, being able to create a duplicate that can cause Chaos Control.

Combat Skills
Though not as seasoned a brawler as most other characters in the Sonic the Hedgehog series, Tails is a quite accomplished fighter. On his own, Tails has defeated several of Dr. Eggman robots and combat mech and even single-handedly fought and defeated the entire Battle Bird Armada and Witchcart and her minions.

Fighting Style
In direct combat, Tails lacks in raw hand-to-hand combat skills and physical superiority. Instead, he focuses more on using his strong points, such as his twin tails, gadgets and intelligence about logic and tactics to aid him in combat and cover his weaknesses.

Normally, Tails focuses primarily on providing support to his allies. In close-quarter battles, Tails relies on his own unique fighting where he uses a blend of basic punches and kicks and foremost strikes with his trademark twin tails. When applying his twin tails in combat, Tails can use them to lash out at his foes by twirling them around or swinging them like a whip, allowing him to deal significantly stronger strikes with greater range than what he normally would be capable of with his legs and arms. When not fighting opponents head-on, Tails focuses on aerial combat, taking it to the air from where he has aerial and mobility advantages over his opponent and can launch aerial attacks at foes or fly at them with greater speed to build up charges.

As shown on several occasions, to complement his chances in more fierce battles, Tails often uses various mechanical devices of his own creation, such as his Magic Hand, Energy Cannon and Big Hand as seen in in Sonic Battle, to improve his battle prowess in close combat. Another example is his Cyclone mech, which he used to destroy G.U.N.'s numerous forces in Sonic Adventure 2.

Techniques and Moves
Tails' trademark attack is his Tail Swipe technique, where he twirls his twin tails around to attack his opponents, and has developed several unique attacks from it, such as his Super Tail Swipe, a much faster version of the regular variant, his Rapid Tails Attack, which enabled him to attack with his twin tails by continuously spinning around, and his Tornado Attack, where he spins his tails around like a tornado.

Tails also can perform the Spin Attack, Spin Jump and the Spin Dash, having possibly learned them from Sonic.

From Sonic Heroes and onward, Tails has been shown using several Dummy Ring attacks. The first attack is "Dummy Ring Bomb", which throws multiple Dummy Rings that explode on impact, "Dummy Ring Snipe", which allows him to aim and throw a Dummy Ring, and "Dummy Ring Blitz", which throws a huge amount of Dummy Rings to explode on impact.

Miscellaneous Skills
As shown with his various Tornado biplanes, Tails has excellent air piloting skills, and has aerial dogfighting skills to go along with them, as seen during his and Sonic's attack on the Egg Carrier in Sonic Adventure, and in Sonic Unleashed.

While not only being talented with Extreme Gear mechanics, Tails is also, in his own right, a talent Extreme Gear rider, and possibly one of the best in the world, as he has proven himself capable of going up against the Babylon Rogues, who are considered the best Extreme Gear riders in the world. He also has enough skills to ride his Extreme Gear through mid-air with great precisions and control over his movements.

Super Transformation
Like Sonic, Knuckles and Shadow, Tails can initiate a super transformation into Super Tails. Because of his young age, however, he required their enhanced version, the Super Emeralds to do so and has so far only done it in Sonic the Hedgehog 3 &amp; Knuckles. In this form he gains invincibility, greater speed and strength and can control four Flicky birds that attacks any enemy.

Weaknesses
Tails has a tendency to talk too much as shown in Sonic Adventure 2 when he reveals to Dr. Eggman that the Chaos Emerald Sonic was trying to give him was a fake. He is also said to be afraid of lightning, otherwise known as astraphobia, and ghosts, as he can be sometimes heard screaming when ghosts appeared in Hang Castle and Mystic Mansion on Sonic Heroes.

Tails occasionally lacks self-confidence but has been shown to get over this weakness on some occasions.

Tails also says in Sonic Heroes, Shadow the Hedgehog, and Sonic the Hedgehog (2006) that he gets dizzy easily; although this apparently does not affect him when he uses a Spin Dash, Tails Attack, Rapid Tails Attack or Spinball Jump. In Sonic the Hedgehog 4: Episode II, Tails can be seen with stars over his head indicating dizziness after performing a Tornado Combo, though this only happens if he crashes into something, signifying that he is dazed due to the impact.

Relationships
Tails has many friends besides Sonic, and his skills are respected by everyone who knows him. Tails mostly treats and respects all his friends the same with a humble and somewhat passive attitude.

Sonic the Hedgehog
Sonic is Tails' best friend, as the two have been inseparable since they first met shortly before the events of Sonic the Hedgehog 2. On Westside Island, Tails saw Sonic running at incredibly high speeds. He was impressed by the cool blue hedgehog and began to follow. Sonic eventually stopped and the two became close friends. He began to hang out around Sonic at all times of the day, catching up with him using his two tails. Eventually, Tails spotted Sonic's Tornado plane, which he grew fond of and is usually seen borrowing it.

Sonic and Tails were always there to help each other, their friendship growing until they had a more brotherly relationship. It is often that Tails invents machines for Sonic in his help and also made him three Extreme Gears. In Sonic Advance 3, they are known as the "Unbreakable Bond" when they team up. In Sonic Rivals 2 it is shown that Sonic trains Tails to learn how to run and fight in their free time. Whenever Sonic has an adventure to explore, he always comes to Tails and asks him to come along and Tails is always ready to help. Tails also used to depend on Sonic a lot, but later realized that he cannot depend on him forever. Sonic is also an idol to Tails, and Tails just wants to be as heroic as he is.

Despite his admiration of him, Tails can sometimes get impatient and annoyed by Sonic's fast-paced behavior and attitude. He downright hates when Sonic ignores him as seen in Sonic Adventure, and he gets annoyed when Sonic leaves him hanging when he runs off or when he is planning to do reckless things without much thinking, such as when Sonic planned to just smash the Extractor in Sonic Lost World. Despite facing such cases though, Tails remains loyal to Sonic and stands by his his side to aid him no matter what.

In Sonic Colors, Tails was great help to Sonic and was with him throughout the game. Tails cares enough for Sonic to even sacrifice himself to be a victim of Eggman's mind-control whilst pushing Sonic out of the way. Tails also embarrassed Sonic when he was talking to a giant broken robot and continues to tease him about it. In the end, he however doubted that Sonic could beat Eggman and was impressed when Sonic was able to not only do just that, but also live through the following explosion.

In Sonic Generations, Tails threw Sonic a surprise birthday party and made Sonic a special Chili Dog. Tails was the first one restored in the White Space and remains with Sonic for the remainder of the game and story. Tails and Sonic talk about the strangeness of the areas that they are going though like the Green Hill that looked like "Someone sucked all the life and color out of it".

In Sonic Lost World, Tails' friendship with Sonic became strained when they formed an alliance with Eggman. Believing that Sonic trusted Eggman, his own nemesis, more than him to shut down the Extractor, Tails became rather frustrated and angry at Sonic's lack of faith in him and even got into an argument with him when he told about how much it hurt thinking that Sonic trusted Eggman more. It became further strained when Sonic scolded Tails for putting Cubot's head on a battle mech, which caused Cubot to almost kill Tails. At the end of the game though, Sonic apologizes for doubting Tails and Tails forgave him, mending their brotherly bond.

Amy Rose
For the most part, Amy Rose and Tails have a very friendly relationship as they are usually together when they and Sonic are out saving the world. Tails, Sonic, and Amy interact with each other often because Amy usually tries to tag along with Sonic and Tails when they are trying to beat Eggman, thus making them friends along the process. Sonic uses Tails to distract Amy in order to escape from her or avoid contact during mission, Tails usually responds to this with a lack of confidence.

Amy also looks at Tails as a little brother figure, and this was shown when Wave the Swallow insulted Tails, where Amy got infuriated whilst challenging Wave to a race. Tails has also saved Amy numerous times when Sonic could not, to which she is very grateful. When the Egg Carrier was losing altitude and about to crash Sonic told Tails to act quickly and take Amy to safety. Tails also saved Amy a few more times from Eggman on Prison Island, as well as saving Amy along with Sonic from the exploding Prison Island, and finally saving Amy from Eggman on the Space Colony ARK at gunpoint.

Knuckles the Echidna
Tails is also good friends with Knuckles. They converse more than Knuckles does with Sonic, and although he is not as much a rival to Knuckles as Sonic is, Tails does occasionally tend to irritate Knuckles with his technobabble. Knuckles seems to enjoy teasing Tails from time to time, such as when he scares Tails with the idea that they fought with Shadow's ghost just before Hang Castle Zone in Sonic Heroes. Despite this, Knuckles is probably Tails' closest friend after Sonic. Knuckles has shown that he cares for Tails, such as when he furiously defended Tails after Wave mocked Tails in Sonic Riders. Even though they are good friends, Tails and Knuckles have fought each other numerous times, usually when Knuckles has been tricked by Eggman, but in the end, there are never hard feelings between them.

Dr. Eggman
In every game since his debut, Tails has been one of Eggman's biggest enemies along with Sonic, whether he is against him head on or helping out Sonic in any way he can. At first, Tails was useful as a hostage, which later turned into a worse situation for Eggman. Eggman's plans are always foiled by Sonic and Tails, sometimes because he targets one and forgets about the other (this occurred in Sonic Adventure 2, when Eggman was stopped by Tails on the Space Colony ARK after he blasted Sonic into space; it also happens in numerous episodes of Adventures of Sonic the Hedgehog).

In Sonic Adventure, Eggman had to race Tails to the missile he launched into Station Square, but could not reach it in time. He retaliated by using the giant Egg Walker, but was again stopped by Tails. In Sonic Adventure 2, Tails had a rivalry with Dr. Eggman, fighting him directly in the Cyclone twice - once on Prison Island (to which Eggman said "I can't lose to Tails!" after being defeated), the second time on the Space Colony ARK, after Eggman blasted Sonic into space. After this, the rivalry seemed to cease, and Eggman and Tails were seen talking to each other in a somewhat civil way at the end of the game. Eggman also seemed to develop a respect and liking for him during the events of Sonic Chronicles: The Dark Brotherhood, due to their shared skill with machines.

In Sonic Colors, Eggman charged up a mind control beam and shot it at Sonic, but Tails quickly pushed Sonic out of the way so that he got hit instead. Eggman used this to his advantage and made Tails run at supersonic speeds to block Sonic's way. Eggman then dared Sonic to fight his best friend to get to him, but Sonic refused. Eggman kept pushing and prepared Tails for an attack, but the mind control device then ran out of energy.

In Sonic Generations, Classic Robotnik asked Modern Eggman who all of Sonic's "modern" friends were. Modern Eggman's reply was that they were insignificant and that they should only worry about Sonic and Tails, believing they are the only real threats.

In Sonic Lost World, Tails dislikes working with Eggman even more than Sonic does, making a comment about Cubot's voice chip looking like it was made by a two-year-old and wanting to fight him. However, Eggman later saves Tails from being attacked by an aggressive Cubot. After Tails is captured, Eggman says they should make sure Tails' sacrifice wasn't in vain. They become enemies again after the Deadly Six are defeated and Eggman reemerges as the villain.

Shadow the Hedgehog
Shadow and Tails were at first enemies in Sonic Adventure 2 because Shadow was impersonating Sonic and got him thrown in jail at Prison Island. Towards the end of the game they became Allies when they had to save the planet from the Space Colony Ark. For the most part Tails and Shadow have remained allies, but like Sonic have turned into rivals because of their goals.

Such times they have been rivals are in Sonic Heroes, Sonic Battle, and Sonic Rivals 2. In Sonic Heroes they fought very briefly because Shadow and Rouge had provoked Team Sonic into fighting them. In Sonic Battle Shadow and Tails fought at the end of Tails' Story because Tails resisted giving up Emerl to Shadow. Shadow threatened Tails that he would have to give Emerl up or else they would fight for him, Tails admitted that he admires Shadow's spirit but would not give up in a fight. When Tails won the fight Shadow warned him that he would be back again to get Emerl, but Rouge showed up and told Shadow to go back to Night Babylon. In Sonic Rivals 2. Shadow and Metal Sonic confronted Tails and Sonic because they were all going after Eggman.

Shadow and Tails also get along very well together. In Sonic Chronicles: The Dark Brotherhood, Tails and Shadow work very well together and support each others ideas. Also, when Eggman suggests they build a weapon to hurt the enemy, and Tails says he has a better idea, Shadow with a smile asks why he is not surprised. Shadow is actually the second most helpful member of Tails' Team in Metropolis, helping Tails with numerous mechanical ideas with Eggman. He is also very helpful if the player is looking for Omega often giving tips to tell of where Omega would have gone if he gotten the chance. If the player succeeds in finding Omega, Shadow thanks Tails for helping him.

Wave the Swallow
Wave and Tails are rivals in inventions, since they both are smart. In Sonic Riders Wave was impressed by Tails' inventions but could not admit it saying that he made "a piece of junk". She teases Tails by calling him "shorty". In Sonic Riders: Zero Gravity, the two do not seem to rival each other in anything. When Wave was hurt by the robots in the game, Tails is seen in the screen trying to help her get up. In Sonic Free Riders, she keeps the same attitude towards him like how she was in Sonic Riders. Once again, they do not talk much or show much rivalry until in one scene when Tails examines the gears and compliments it. Wave, however, does not take his comment seriously and rudely asks him if he was being sarcastic.

Rouge the Bat
Tails and Rouge have a friendly relationship but Rouge sometimes adds complications to it. They will usually get along but Rouge will sometimes playfully tease Tails to get a reaction from him.

In Sonic Adventure 2, Tails was basically unaware of Rouge's presence, but this was because Rouge was sent by Eggman to spy on Tails when he was trying to find the President. After that their interaction stopped until the Ark was set on its collision course with Earth. In Sonic Battle, Rouge would use her charm to tease Tails because she thought it was cute and funny how he reacted. She was however very helpful in Tails' story as she gave him the access card for the Central Computer Room, distracted Shadow, and told Tails how to escape the Guard Robos. Later on in Rouge's story Tails had to stop Rouge from stealing a Chaos Emerald. In Sonic Chronicles: The Dark Brotherhood, while in Metropolis Rouge would sometimes be snarky with the plans Tails and Eggman would come up with but still show a playful affection for Tails.

Cream the Rabbit
Tails and Cream are good friends with each other either by supporting each other or just spending time with each other. Throughout the games there is not much contact between the two but it is understood that they get along very well when they are shown throughout some story cutscenes.

The only game they have really interacted with each other is in Sonic Free Riders, Tails said that Cream's Extreme Gear was really good in the race to which Cream replied "Well, sure! That means a lot coming from you, Mr. Tails!". They also interacted in Sonic Rush in which Tails is protective of Cream, telling her to stay away from Blaze as she was a suspect. Cream also compliments Tails to Blaze telling her that he is "neat".

In some games Cream is Amy's equivalent of Tails to Sonic, often helping Amy out or trying to get her out of bad situations like Amy's compulsion to push herself too far especially when aroused to anger.

E-123 Omega
Currently Tails is the only one of Sonic's friends to have even spoken to Omega, with the others including Sonic only briefly coming into contact, either not knowing who he is or fighting him like in Sonic Heroes. While Tails was leading his Team through Metropolis in Sonic Chronicles: The Dark Brotherhood, he had to try and convince Omega to join their team and believe that Eggman was on their side. Omega replied saying Tails was crazy for believing that Eggman could be good, however was convinced by Shadow to believe Tails. Later on Tails asked Omega for help with the credits for the end of the game.

Tails' Mechanical Creations
Although Tails can fly by twirling his two tails like the blades of a helicopter, he also enjoys flying Sonic's red biplane, the Tornado. As the series progressed, it was obvious his interest in the old biplane went further than just piloting it - Tails is a prodigy with mechanics, and he has a mechanical ability equal to that of Dr. Eggman's (though Tails has not appeared to have built a completely sentient robot). As a result, many modifications were made to the Tornado, as well as new biplanes and a small, blue submarine called the "Sea Fox", a spaceship called the "Lunar Fox", and a race car called the "Whirlwind S7," which is clearly based upon the Lotus/Catherham Super Seven (hence the name). In Tails Adventure he built a small remote-controlled robot in his image to help him on his quest.

In Sonic Adventure, Tails was experimenting with a Chaos Emerald-powered prototype plane based on the Tornado, Tornado 2. The Tornado 2 has two modes: one is quite similar to the original Tornado, but with a button press, Tails could make it transform into a rather futuristic-looking little plane which outperformed the Tornado in all but one important function - landing gear. Big the Cat ended up flying the wrecked Tornado 2 to his home after Sonic and Tails crash-landed on Eggman's flying fortress, the Egg Carrier.

In Sonic Adventure 2, Tails had a new plane, the Tornado III. The Tornado III has three modes: a plane mode, a car mode, and a walker mode. The airplane is only seen in cut-scenes; the car is used on only one level (In the Kart mini game, Tails uses a go-kart); the walker mode, called the Cyclone, is used most during the game. Tails uses the Cyclone during all other gameplay, except when visiting the Chao Garden. The old Tornado 2 then appears in cutscenes in both Sonic Heroes and Sonic Riders. In Shadow the Hedgehog, the Tornado III reappeared as its Sonic Adventure 2 version.

In Sonic Battle, Tails comes equipped with an arm cannon that fires electrical energy, presumably of his own invention.

In Sonic Rush Adventure, Tails constructs six new vehicles with the first four being playable while the last two only appear in cutscenes. The first is the Wave Cyclone which is a water-bike that has a effective boost function that can plow through enemies, a sail boat called the Ocean Tornado that is armed with machine guns, cannons and a flamethrower, the hovercraft Aqua Blast that has a charged beam function and can spin, the Deep Typhoon is a submarine that carries missiles and the last of the water crafts is the SS Tornado EX that can do dimensional travel. The last one is the only vehicle that does not travel on water, the Magma Hurricane that is a drilling vehicle.

Tails brings along portable machines during the events of Sonic Chronicles: The Dark Brotherhood, focusing on aiding allies and weakening enemies as a "Support" character. In the game, he and Eggman build the Cyclone, a starship for Sonic and his friends to travel into the Twilight Cage.

In Sonic Unleashed, Tails has seemingly invented a portable monitor labeled "Miles Electric" that can apparently pick up and process satellite imaging, as demonstrated when Tails uses it to show Sonic and Chip that a part of the planet has been put back into place. Tails is frequently seen with this device in one hand during the game, and during portions of the game featuring flying on the Tornado, this same device, or a similar device is used as a sort of on-board computer for the Tornado. It can also be seen during most loading screens.

The "Miles Electric" also appeared in Sonic Colors, where Tails built a translator into it, thus playing an important role in the game as he was able to get information about the Wisps and Eggman's plans from Yacker, a white Wisp which was saved by Sonic.

In Sonic the Hedgehog 4, Sonic uses a red rocket to chase Eggman to the E.G.G. Station Zone. The front of the rocket has Tails' twin tails symbol on the front. Later, Metal Sonic would use the same rocket to catch up to Sonic and Tails in White Park Zone.

In Sonic Generations, Tails builds an unnamed transmitter that allows him and Sonic's other friends to communicate with the two Super Sonics during the final battle with the Time Eater.

Tails is one of the few characters in the series who has used firearms and missiles. Of the few characters, Tails is the only one of Sonic's friends and the only hero who has used firearms and missiles. Shadow is an anti-hero or neutral and Dr. Eggman is a villain. Tails has built multiple firearms, from machine guns and vulcan cannons to missile launchers, and he built the ammunition for them as well. Tails has built these into multiple of his devices so he can fight evil, but he has also used a few by hand.
 * Some of the games Tails has used firearms are listed below.
 * Tails Adventure, Tails utiles numerous weapons, most notably bombs.
 * Sonic Adventure, machine gun and homing missiles built into the Tornado and Tornado 2.
 * Sonic Adventure 2, vulcan cannon, bazooka and homing missiles built into the Tornado 3.
 * Sonic Battle, arm blaster cannon and Chu2 Bombs.
 * Sonic Rush Adventure, missiles, bombs, machine guns and flamethrowers built into multiple crafts.
 * Sonic Unleashed, missiles built into the Tornado.
 * Sonic & All-Stars Racing Transformed, All-Star Move that summons two mini Tornadoes that initiate full-auto on machine guns, missiles, and bombs onto other racers.

Adventures of Sonic the Hedgehog
In the Adventures of Sonic the Hedgehog television series, Tails is a "four and a half"-year old kid and the adopted younger brother of Sonic the Hedgehog. When he was just an infant, Miles stumbled across Sonic and convinced him to let him stay with him. Because Miles hated his name, Sonic gave him the nickname "Tails." In the years that followed, Tails remained at Sonic's side, becoming a Freedom Fighter, and together they would defend the citizens of Mobius from Dr. Ivo Robotnik and his lackeys Scratch and Grounder.

In this media, Tails is very innocent, gullible and naïve due to his young age, leaving him susceptible to getting caught in the villains' schemes. As such, Sonic often has to rescue Tails, though he is not completely helpless. While he is also not highly intelligent, he has at times proven himself a mechanical genius, coming up with inventions stunning even brilliant minds.

Sonic the Hedgehog (TV Series)
In the Sonic the Hedgehog television series, Tails is a ten year-old and big-hearted kid, and a close friend of the Knothole Freedom Fighters, who he views as his adopted family. He especially looks up to Sonic in every way and sees him as a "big bro."

During the tyrannical rule of Dr. Robotnik, Tails was often left behind in Knothole while the Freedom Fighters went on missions to stop Robotnik because he was too young. Tails, however, often expressed his desire to be involved in the freedom fighting cause which would make him jump into things too fast. After Tails came up with a plan that saved the Freedom Fighters and secured a Deep Power Stone, which proved vital in the final defeat of Robotnik, however, he was decreed a real Freedom Fighter by Sally.

Sonic the Hedgehog: The Movie
In the OVA entitled Sonic the Hedgehog: The Movie, Tails lived on Planet Freedom, serving as one of the defenders of the Land of the Sky alongside Sonic, where they protect it from the Dr. Robotnik and his evil forces. He lives together with Sonic on their own private island.

One day, Tails and Sonic were unexpectedly called by Dr. Robotnik to defeat an evil robot named Metal Robotnik and save the world from utter destruction. This was however a trick on Robotnik's behalf so the evil doctor could copy Sonic's data for his Hyper Metal Sonic robot. After the doctor's plan worked, Tails, along with their friends and allies, aided Sonic to combat the new enemy and to save Planet Freedom.

Sonic X
In the anime series Sonic X, Tails originates from a parallel version of Earth in another dimension. While shy at times, he can be very brave and strong in his words. On his world, Tails befriended Sonic when fixing up his bi-plane. During one of their battles against Dr. Eggman however, an accidental large-scale Chaos Control send Tails, Sonic, Dr. Eggman, and their friends to the human world. After landing on this world, Tails reunited with Sonic and befriended Christopher Thorndyke and his family, especially fellow inventor Chuck Thorndyke, who he forms a close friendship with.

On this new world, Tails and his friends fought against Dr. Eggman as the doctor attempted to conquer the planet. After living with Chris for a while, Tails set out on his own and build his own lab. In the end though, Tails and everyone else from his world were forced to return home as their presence threatened to freeze time. As such, Tails and Chuck built a portal for them to return to their own world with.

Six months after returning home, Tails and his friends teamed up again to fight the impending threat of the Metarex, an alien race of cyborgs who were a threat to the entire galaxy. Along the way, Tails found a love interest in Cosmo, a plant-like alien girl. In the final battle with the Metarex, however, Tails was forced to sacrifice Cosmo to stop them, much to his sorrow. Upon returning to their home planet, Tails rejoined Sonic as they resumed their ongoing battles with Eggman.

Sonic Boom
Tails will appear as one of the main characters in the new upcoming series Sonic Boom. In this media, he serves as his group's gadget specialist and pilot.

Sonic the Comic
Tails also appears in the British Sonic the Comic, published by Fleetway, where he hails from the Nameless Zone, a region which can apparently only be accessed by a space warp. He traveled to the Emerald Hill Zone after mistakenly believing that the streets were paved with real emeralds. Once on Mobius he met and befriended Sonic, eventually becoming his sidekick. While he is self-conscious, Tails has proven time and again (and openly stated) that he is much tougher than some people may think.

Tails frequently starred in his own solo adventures, occasionally back in his native Nameless Zone or in the Chemical Plant Zone. Over time he built up an extensive rogues gallery including the brutal Trogg, the psychotic robot Nutzan Bolt, Fleabyte the bounty hunter and the gangster Max Gamble, as well as allies such as Errol Blackthorn and Morain, and Sab. He also fought many criminals after the defeat of Robotnik, defended the Casino Night Zone and its people from Brutus' Badniks, and was chosen by Sonic to protect the planet while he went after Robotnik during the Planet In Peril/Game Over story.

Archie Comics
In the Sonic the Hedgehog comic series and its spin-off comic series published by Archie Comics, Tails is a Freedom Fighter and the closest friend of his world's hero, Sonic the Hedgehog.

Tails was born Miles Prower to Amadeus and Rosemary Prower on the day of Dr. Ivo Robotnik's takeover of Old Mobotropolis. While still an infant, he was spirited away to Knothole where he was looked after by Rosie Woodchuck. Startling intuitive for his young age, Miles latched onto a charismatic Sonic and dreamed of becoming a Freedom Fighter. Over time, he earned the nickname "Tails" from his mutation: a par of tails.

While Sonic and the other children became the Knothole Freedom Fighters to fight against Robotnik's tyranny, Tails was only made a junior member and was deemed too young to participate in their missions. With time and experience however, Tails earned his position among the Freedom Fighters as both a warrior like Sonic, but also an inventor like Rotor, and became prominent member of the team who would assist actively in the war against Robotnik and later Dr. Eggman. Throughout it all though, he continues to be at Sonic's side through even the toughest of times.

During his adventures, Tails discovered that it was his destiny to become the "Chosen One" of the Ancient Walkers meant to fulfill an ancient prophecy. Under the guiding hand of Athair, Tails has accomplished many great tasks in the fulfillment of his destiny such as stopping Mammoth Mogul and brining forth the Great Harmony, but his true destiny has proven elusive.

Reception
Tails was awarded "Best New Character" in Electronic Gaming Monthly's 1992 video game awards, stating "not only is he as cute as Sonic, but he actually serves a major purpose in the game."

Tails also came third in an official Sega Sonic character popularity poll, coming behind Shadow and Sonic himself.

 * As proven in Shadow the Hedgehog, Sonic Heroes and Sonic the Hedgehog (2006), Tails seems to get dizzy easily and feels pretty uncomfortable when he gets dizzy. This is an inconsistency concerning the character, due to his "Rapid Tail Spin" attack in Sonic Adventure and the Spin Dash attack.
 * Tails appears to have phasmophobia, the fear of ghosts, first made apparent in Sonic Heroes.
 * The only main Sonic games that Tails has not officially appeared in since Sonic the Hedgehog 2 are Sonic Labyrinth, and Sonic Blast; additionally, the only Sonic cartoon Tails was not ever featured in was Sonic Underground. He also originally only made minor cameo appearances in Sonic CD, but this is no longer the case as of the 2011 re-release.
 * In issue #188 of the GameInformer magazine, Tails had the #6 worst video game character name, mainly because of the "miles per hour" joke.
 * The September 2010 issue of GameInformer magazine elected Tails as the 10th "Most Disgustingly Cute" Video Game Character.
 * In Sonic the Hedgehog: The Movie, Metal Robotnik stated that both Sonic and Tails cannot swim. Oddly, Tails is said to be a good swimmer and can swim in some games.
 * All of Tails' solo theme songs are "Believe in Myself" or some kind of remixed version.
 * As seen in Sonic Colors, Tails can read Binary fluently, although it was shown later that the codes were in Hexadecimal.
 * Nintendo Power magazine had a poll recently asking which sidekick people would choose, with Tails being the second most picked.
 * In Sonic Adventure, in the cutscene after the Egg Carrier shoots down Sonic and Tails (if playing Tails' story), it shows a flashback where Tails is walking in the jungle of the Mystic Ruins and Sonic speeds by, with Tails running right behind him (a reference to how they met). The Mystic Ruins is used for this scene, rather than having to develop an entirely different environment that would only be used once.
 * Modern Tails' artwork in Sonic Generations looks very similar to his Sonic Advance 3 artwork, where as his Classic artwork appears to be completely new.
 * A top ten list by the video-gaming website ScrewAttack named Tails as their #1 pick for Best Sidekicks. However, it should be noted that this was only due to his perceived uselessness in Sonic the Hedgehog 2.
 * It would be physically impossible for Tails to fly, due to his tails having to twist. However, if one slows down footage of him spinning his tails to fly/move, they do not actually turn through morphing of the model, but actually mesh through each other. This minor inconsistency would not normally be noticeable at normal speed, though.
 * Unlike Sonic's classic form, Classic Tails speaks in Sonic Generations. He also refers to Doctor Eggman by his previous name, Dr. Robotnik.
 * Even though Tails is one of the fastest characters in the series, he is a Skill Type in the Mario & Sonic series, due to the fact that there can only be two characters per type, Sonic and Shadow are faster, and Tails is still one of the main characters. This is also the case for Eggman.
 * Tails has the most voice actors out of all of the characters, with nine English voice actors (counting his TV show and movie appearances).
 * A bonus wallpaper, accessed from inserting the Dreamcast version of Sonic Adventure into a computer, shows Tails out of his trademark white-and-red shoes, and instead wearing sandals. This also reveals the shape of his feet.
 * In Spiral Knights, there's a Tails costume for the players where you can wear Tails' tails, along with a Metal Sonic costume.
 * In the game Sonic Generations, Tails doesn't seem to remember Green Hill Zone, although he has been in the level several times in other games. This is mainly since Tails debuted in Sonic the Hedgehog 2, where Green Hill Zone was not present and replaced with a different beginner level/act, but in Sonic Chronicles: The Dark Brotherhood (released three years before Sonic Generations), he seems to know about the zone.
 * In Sonic Generations, Tails' Classic "pose" in the profile section is in the "pose" at the beginning of Sonic the Hedgehog 2.
 * In Sonic Chronicles: The Dark Brotherhood, Tails and Sonic are the only characters in the game that can carry on different conversations via selecting different speech bubbles with the stylus.
 * Tails is one of the few characters in the series to be able to move at super speeds. Despite this, and possessing nearly all of Sonic's abilities, Tails has never been classified as a Speed-type in any of the games.
 * Tails doesn't run, but is instead propelled along the ground by his tails like an airboat.
 * Despite being a fox, Tails has been mistaken for a squirrel; during  Nintendo Power' s run, the magazine would occasionally refer to Tails as a squirrel.
 * In Mario & Sonic at the Olympic Games, Tails is a skill type character and in the series, he's a flight type character.
 * In the bad ending of the 8-bit version of Sonic the Hedgehog 2, it is never confirmed but implied that Tails dies in an alternate timeline.
 * When Tails is turned into a robotic slave in Sonic Lost World, he looks almost identical to his Sonic the Comic counterpart when that version of Tails was roboticized.
 * The heading of Tails' character bio in Sonic Chronicles: The Dark Brotherhood refers to him as Tails the Fox. However, in the first sentence of the text itself, he is called Miles "Tails" Prower and simply Tails afterwards.
 * Tails has won an Olympic gold medal for Uneven Bars as shown in the intro for Mario & Sonic at the London 2012 Olympic Games.
