Miles "Tails" Prower/History and appearances

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, but also made him the target of much bullying. Also, because of his unusually high IQ, Tails became a master engineer.

Tails Adventure
In Tails Adventure, prior to meeting Sonic, Tails had taken up residence on Cocoa Island, living pretty similar days. One day though, while taking a nap in the forest, Tails was suddenly awoken by the sound of explosions. Amidst the chaos, Tails met a frantic Flicky who explained that the Battle Bird Armada, led by Great Battle Kukku 15th, had invaded Cocoa Island in search for the Chaos Emeralds located on the island so their leader could conquer the world. During this, Tails saw Great Battle Kukku 15th leading his battalion through the burning forest. Realizing the threat, Tails mustered all his courage and set out to liberate the island.

While liberating the island and recovered the Chaos Emeralds, Tails gained an enemy in Speedy. When Tails infiltrated the Battle Bird Armada's undersea stronghold, the Battle Fortress, he was trapped by Dr. Fukurokov, but managed to outwit the doctor and escape the Battle Fortress as it rose into the sky. Tails then invaded the Battle Fortress in his Sea Fox, where he defeated Speedy and afterwards Great Battle Kukku 15th for good. Tails then escaped the Battle Fortress in the Sea Fox as it crashed into the sea. Tails then returned to his workshop to built a larger model of his Remote Robot, only to have it explode in his face.

Mega Drive
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 though, he saw Sonic the Hedgehog run past him. Seeing Sonic run like the wind made Tails admire him for how cool he was. With a change it heart, Tails resolved to become as cool as Sonic and began following him. However, Tails was too shy to show himself to Sonic and hid whenever Sonic noticed him. Though Sonic ignored him, Tails still followed him and eventually earned his attention by keeping up with his speed.

During an early afternoon, Tails discovered Sonic's biplane, the Tornado, on the beach. Fascinated by the craft, Tails investigated it, but shyly stayed away from Sonic napping under it. Suddenly, an explosion erupted from the woods, and Tails sought shelter under the Tornado where Sonic stood by him. There, he saw the destruction of the island and Badniks digging in the ground. As Sonic ran into the attack, 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 thus teamed up to find the Chaos Emerald and save the island.

Traveling across West Side Island, the duo claimed the Chaos Emeralds. Along the way, Tails proved to be a great ally 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, but when they got there, Tails and the Tornado were shot down. However, Tails returned in time with a rocket engine-enhanced Tornado to help Sonic get to Robotnik in his rocket ship.

Back on the ground, Tails watched the Death Egg explode thanks to Sonic, and 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 was made his idol's sidekick.

Game Gear/Master System
In Sonic the Hedgehog 2, Tails and the other animal residents on South Island were taken hostage by Dr. Robotnik while Sonic was gone. Imprisoned in the Crystal Egg, Tails wrote a note to Sonic, saying he would need the Chaos Emeralds to reach him. Tails also warned Sonic in the note that Robotnik had his six Master Robots waiting for him. Coming to Tails' rescue though was Sonic, who took the fight to Robotnik. After Sonic defeated him, Robotnik escaped through a teleporter, which Tails shortly after emerged from. Though confused at how he got there, Tails was happily reunited with Sonic and the duo set off for new adventures together.

Sonic Chaos
In Sonic Chaos, Tails was with Sonic on an adventure when they heard rumors about Dr. Robotnik seeking the Chaos Emeralds on South Island. Returning home, the duo found the place in chaos as Robotnik had stolen one of the Chaos Emeralds, thereby creating an imbalance that scattered the rest of the Chaos Emeralds was making the island sink into the ocean. Banding together, Tails and Sonic headed out to recover the Chaos Emeralds and save South Island.

In the ensuring battles, Sonic and Tails recovered the lost Chaos Emeralds except one, before defeating Robotnik in a final battle. Tails and Sonic the 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' Jewel Reader picked up a strong chaos energy reaction out at sea. Connecting to a tidal wave a few days earlier, Tails consult Sonic and the two left in the Tornado to investigate the reaction as their next big adventure.

When Tails and Sonic reached the location, they found the legendary floating isle, Angel Island, except that the island was kept at the ocean's surface by the Death Egg, which Tails thought they had destroyed, but had crash-landed on the island instead, forcing it down into the ocean. Seeing that the Death Egg was currently being rebuilt, the duo set out to destroy the Death Egg for good. When they got to the island however, Knuckles the Echidna, the guardian of Angel Island and the Master Emerald, ambushed Sonic and forced the Chaos Emeralds out of Sonic just as he turned into Super 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 to hide them.

Despite this, Tails and Sonic continued onward, traveling across Angel Island to freed it from Robotnik's control. Along the way, Tails and Sonic were repeatedly ambushed by Knuckles, but the duo survived each encounter, and recovered the Chaos Emeralds. Arriving in Launch Base Zone, Tails and Sonic got onboard the Death Egg just as it took off, where Robotnik had come to smite Sonic with excessive force. Sonic still defeated Robotnik, 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 Tails and Sonic landed in the Mushroom Hill Zone after escaping the falling Death Egg, they saw the space station survive another crash landing, this time into the island's volcano. The duo thus left once more to find the Death Egg and destroy it and as well discover Robotnik's fate. While passing through Mushroom Hill Zone, Tails and Sonic saw Knuckles coming through a hidden doorway. Once Knuckles was gone, Tails and Sonic looked 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. Riddled with questions, Tails and Sonic returned to Mushroom Hill to continue their search.

Eventually, Tails and Sonic got to the Hidden Palace Zone on their own, where Sonic defeated Knuckles. Tails and Sonic then followed Knuckles as he went to check the Master Emerald, where they saw Robotnik steal it so he could power the Death Egg. As Knuckles realize he had been duped as Robotnik fled, he befriended Tails and Sonic and guided them to Sky Sanctuary Zone to reach the Death Egg, but because Knuckles was too exhausted from the last struggles, they had to leave him behind. On their way through the sanctuary, Sonic and Tails fought Eggrobos and Mecha Sonic several times, where they in the final encounter used a crumbling pillar to get on the Death Egg.

On board the Death Egg, Tails and Sonic fought Dr. Robotnik in a final showdown in Great Eggman Robo. Upon defeat of the contraption, which resulted in the Death Egg's complete destruction, Sonic gave chase to Robotnik in space as the doctor escaped with the Master Emerald while Tails returned to earth. There, he caught Sonic on the Tornado when he returned with the Master Emerald. The two of them then towed the Master Emerald back to Angel Island where it belonged. Tails and Sonic then made peace with Knuckles before departing themselves.

Sonic the Hedgehog Triple Trouble
In Sonic the Hedgehog Triple Trouble, Tails and Sonic heard that Dr. Robotnik had lost the Chaos Emeralds following a weapons test and sprung into action to find them. As they collected information however, Tails and Sonic suddenly met Knuckles. Knuckles, having been tricked by Robotnik into thinking they wanted the Chaos Emeralds for the wrong reasons, gave them a warning before leaving.

Despite several threats, Tails and Sonic recovered all but one of the Chaos Emeralds while confronting the nuisances of Knuckles and Fang the Sniper, the latter who wanted the Emeralds for profit. When arriving at the Dr. Robotnik's base, Tails and Sonic faced and beat Metal Sonic, Fang and finally Robotnik for good while retrieving the final Chaos Emerald from the doctor. Tails and Sonic then freed Knuckles from imprisonment and made peace again before taking off on the Tornado to find new adventures.

Tails' Skypatrol
In Tails' Skypatrol, Tails left Sonic to find an adventure of his own. He eventually found a small island which was 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 from an approaching cart and hid. From his hiding place, he saw an old witch named Witchcart arrive and claim the island as her own while threatening to turn those that opposed her into crystal. As Witchcart left with her henchmen, Tails pursued the villains, firm with determination to save the island.

Giving chase to Witchcart, Tails took out Witchcart's henchmen Carrotia, Bearenger, and Focke-Wulf, before catching up to Witchcart and defeating her. With Witchcart and her henchmen contained, Tails left the island, joyous about his victory.

Sonic Labyrinth
In Sonic Labyrinth, Tails had left Sonic to go on a solo journey. As such, he was unable to help save Sonic when Dr. Robotnik launched his latest plot to defeat the hedgehog a few days later.

Sonic the Fighters
In Sonic the Fighters, Tails discovered that armies of robots were laying waste to everything peaceful place on the planet. Tails suspected that Dr. Robotnik was behind this, but had no clue as to where the robots were coming from. Luckily, Tails received an emergency message from Espio that contained a video of where the robots originated from: Robotnik's newest orbital space station, the Death Egg II. Fortunately, Tails had invented the Lunar Fox, a vessel that could reach the Death Egg II. However, the vessel had only one seat and needed all the Chaos Emeralds to take off. As such, Tails and Sonic set off to gather the Emeralds from their friends (and enemies), who were safeguarding them, from around the globe so Sonic could use the Lunar Fox. On their first stop however, Sonic and Knuckles (one of the Emerald guardians) got into an argument over who was strong enough for the mission to destroy the Death Egg II. Before the two frenemies could fight, Tails got between them and convinced them to fight fair and squarely over the spot in the ring with the other Emerald guardians, and the one who could win against all the contestants got to ride the Lunar Fox. A fighting tournament was subsequently established.

At the end of the tournament, the victor used the Chaos Emeralds to go to the Death Egg II and made it self-destruct moments after escaping it.

Sonic 3D Blast
In Sonic 3D Blast, Tails traveled to Flicky Island with Sonic and Knuckles. Having heard legends about the island's Flickies' being the key to find the Chaos Emeralds, the trio journeyed to there to find these birds. When they got there, however, the island was in pandemonium because of Dr. Robotnik who had established a base on the island from where he turned the Flickies into Badniks and used them to search for the Chaos Emeralds on the island. Thus, Tails and Knuckles joined forces with Sonic and helped him find the Chaos Emeralds while Sonic saved the Flickies and defeated Robotnik.

Sonic R
In Sonic R, Tails was with Sonic on an adventure when they saw an advertisement of the World Grand Prix, a racing competition to determine the fastest in the world, and Tails suggested to Sonic that they should enter. At first, Sonic was not interested, but when he saw Dr. Eggman on the list of participants he left to register, leaving Tails to chase after him. At the Grand Prix, Tails competed with not only Sonic, but also their friends, new and old enemies, and Dr. Robotnik, who were using the others to locate the Chaos Emeralds on the race tracks. At the conclusion, Tails and the others secured the Chaos Emeralds before Dr. Robotnik, foiling 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, where he made the Tornado 2, with a Chaos Emerald he found as a power source. During a test flight however, the aircraft crashed at the beach where he met Sonic. Tails took Sonic to see his project but encountered Dr. Eggman who demanded Tails' Chaos Emerald. Despite beating Eggman's Egg Hornet, the doctor snatched the Chaos Emerald and revealed Chaos, whom he transformed into Chaos 1 with the Emerald and told his plan to make it invincible with all seven Chaos Emeralds and then build Robotnikland upon Station Square. Tails thus left with Sonic to find the Emeralds before Eggman.

Tails and Sonic soon found two Chaos Emeralds, but they then were ambushed by Dr. Eggman with sleeping gas who took one of their Emeralds. Unshaken, Tails and Sonic soon found one another Chaos Emeralds but were then attacked by Knuckles, who Eggman had duped into believing they had stolen parts of the Master Emerald. In the ensuing fight, Tails and Sonic lost their Chaos Emeralds, which were taken Dr. Eggman and given to Chaos 2, turning it into Chaos 4, who Tails and his friends beat. As Eggman escaped in the Egg Carrier, Tails and Sonic followed him in the Tornado but were shot down.

When landing, Tails was briefly knocked out and had a dream of his first meeting with Sonic. To get the Egg Carrier, Tails figured they needed the Tornado 2 and found a Chaos Emerald for it which was taken by Froggy. When he caught Froggy, Tails met a mysterious light that took him into the past where he met Tikal. Back in the present, Tails had a brief meeting with Big the Cat who had been looking for Froggy who quickly fled. Fortunately, Tails got the Chaos Emerald back and used it for his Tornado 2 to look for Sonic. When he found Sonic, Tails took him to the Egg Carrier where Amy was held captive. When they found Amy with Eggman however, they had a brief skirmish with E-102 Gamma attacked them. As Egg Carrier then began to lose altitude, Tails flew Amy to safety upon Sonic's orders.

Bringing Amy to Station Square, Tails saw Dr. Eggman firing a missile in an attempt to destroy Station Square, only for the missile to turn out to be a dud. When Eggman left to detonate it, Tails realized he could not depend on Sonic to save him this time and that he needed to do this himself. Though Tails got to the missile and disarmed it, Eggman unleashed his Egg Walker to attack him. Keeping confidence in his independence, Tails fought and defeated Eggman all by himself. Afterwards, he was hailed by Station Square's citizens as a hero and soon met up with Sonic again.

Following that, Tails left to find the Tornado 2 when he learned Angel Island had fallen. As he and Sonic when there, they found both Knuckles and Eggman and learned that Chaos was still alive, had rebelled, and now had six Chaos Emeralds. Sonic and Tails soon headed out to find the last Chaos Emerald in the Tornado 2 before Chaos, but Chaos beat them to it. Tails then traveled to Station Square which was attacked by Perfect Chaos, where 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. After Super Sonic had defeated Perfect Chaos and neutralized its negative chaos energy, Tails watched Chaos depart with Tikal but then noticed Sonic had already left for his next adventure.

Sonic the Hedgehog Pocket Adventure
In Sonic the Hedgehog Pocket Adventure, Tails was flying around in the Tornado when Sonic suddenly landed on the plane. With Sonic turning out to be chasing Dr. Eggman, who had stolen a Chaos Emerald, Tails helped get Sonic to Dr. Eggman's aerobase. Tails was later reunited with Sonic when the hedgehog landed on Tornado in his Super State after defeating Eggman. As the Chaos Emeralds then scattered themselves, thus returning Sonic to normal, Tails would head out with Sonic in search of new adventures.

Sonic Shuffle
In Sonic Shuffle, Tails, Sonic, Knuckles, and Amy were suddenly taken to the Temple of Light in Maginaryworld. There, they met Lumina Flowlight who had brought them here to help her restore the Perfect Precioustone which had been shattered by Void and made its protector, Illumina, vanish. If the pieces remained lost, Void would destroy Maginaryworld, so Tails and the others agreed to help. While recovering the Precioustone pieces and restoring the places affected by Void, Tails occasionally met Void in his dreams. Though they initially opposed Void, Tails and his team soon saw that Void was lonely and sad which touched their hearts, and they realized that he and Lumina were two halves of the same being.

After regathering the lost Precioustones in the Temple of Light, Tails' team was forced to head there when Void went for the Perfect Precioustone. There, Void turned into a monster as his despair peeked. After beating Void, Tails and his friends found Lumina in despair since the Perfect Precioustone was not recovering. When Sonic found Void in the form of a dark gem, Tails helped Lumina accept Void by elaborating on how negative feelings were needed for dreams to exist. Having cheered up Lumina, Tails and the others saw her restore the Perfect Precioustone, and Lumina and Void merging back into their original form, Illumina. With Maginaryworld restored to an even better place, Tails and the gang received Illumina's gratitude before returning home.

Sonic Adventure 2
In Sonic Adventure 2, Tails was rewarded with a Chaos Emerald from Station Square for saving the city from Eggman's missile during the Chaos incident. One day, Tails caught a broadcast that Sonic had been arrested for robbing a federal reserve bank. Refusing to believe this, Tails headed for Prison Island in his Cyclone where Sonic was imprisoned to free him. There, he found Amy being chased by Dr. Eggman, where he defended Amy until Eggman left. Hearing Amy had come to free Sonic too, they teamed up and successfully infiltrated Prison Island to freed Sonic. When the island then began to explode, Tails, Sonic and Amy escaped 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 world control within 24 hours or he would fire at earth. Figuring he could use his Chaos Emerald to locate Eggman due to the Emeralds' attraction, Tails got to work while Sonic distracted the police as they arrived. However, Tails was unable to get a signal and instead found a transcript in the President's limousine which they could use to find Eggman. Contacting Sonic on his findings, the two 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 to the ARK so they could destroy the Eclipse Cannon. When they reached the center of the base, the group was ambushed by Eggman and his Egg Golem. While Sonic defeated the Egg Golem, Tails and the others got a space shuttle 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. On board, Tails provided a plan; giving Sonic a fake Emerald he had made, Tails told Sonic to insert it into the Eclipse Cannon when he shut off the power, thereby destroying the Eclipse Cannon from the inside. On route however, Tails learned that Amy was held captive by Eggman and was threatened to be killed unless they gave Eggman their Chaos Emerald.

Meeting up with Sonic at Eggman's location, they planned to have Eggman take their fake Emerald. Eggman, however, saw through this when Tails accidentally confirmed Eggman's suspicions that the "Chaos Emerald" Sonic was going to give him was fake. Tails was then entrusted by Sonic to finish the fight as Sonic was rejected into space in a capsule that soon exploded, Determined to fulfill Sonic's last wish, Tails defeated Eggman, but then received to his joy a transmission from Sonic, revealing he had survived the explosion (though his excitement distracted him from Eggman who took his Chaos Emerald) and watched Sonic destroy the Eclipse Cannon.

As Tails met up with everyone, 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 humanity for the death of his granddaughter, Maria. Banding together with Eggman, Tails and the group came up with the 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. Tails soon got Sonic and Knuckles to the core, but after deactivating the Chaos Emeralds, the Biolizard merged with the ARK, becoming the Finalhazard and kept it on its collision course. Soon after, Tails provided advice to Super Sonic and Super Shadow over transmissions as they fought and defeated the Finalhazard. Following the Space Colony ARK's return to orbit after the defeat of the Finalhazard, Tails found Sonic returning alone, informing them that Shadow had seemingly died in the fight. Tails then had a heart-to-heart talk with Eggman about Gerald 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 through 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 so he could turn each region into a part of the Eggman Empire. Tails and Sonic thus set out 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, G-merl, 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 G-merl and welcomed him back before following him out on new adventures. When G-merl's remains were later discovered by Cream and her mother, Tails rebuild the robot and restored his predecessor's friendly personality.

Sonic Pinball Party
In Sonic Pinball Party, right after Sonic had foiled another of Dr. Eggman's attempts at world domination, Tails got brainwashed by Eggman, who made Tails serve him. When Sonic later came to stop Eggman's latest scheme by participating in Casinopolis's Egg Cup Tournament, the mind-controlled Tails took part in the tournament in an effort to stop Sonic. When Tails and Sonic faced off in the second round however, Tails was defeated by Sonic, which restored the fox cub's free will. He and Eggman's other prisoners were soon after liberated when Sonic defeated Eggman.

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 for security to deny them access to it. 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 robots, 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.

Some time later, Tails was practicing with Emerl and Sonic when Amy arrived, scaring Sonic off. Tails told Amy about Emerl but accidentally made Amy think Sonic was practicing 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 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 received their Super States from Sonic when 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.

Sonic Jump (2005)
In Sonic Jump, Tails called Sonic one morning to warn him that Dr. Eggman had obtained a Chaos Emerald for an unknown purpose. When the connection proved too weak however, he told Sonic to meet up with him at his research facility. By the time Sonic arrived though, Tails had been kidnapped by Eggman, who escaped with Tails in a helicopter and imprisoned him onboard Eggman's flying fortress. Fortunately for Tails, Sonic soon came to his rescue. However, as Eggman made his escape, he warned Sonic that he had obtained six of the Chaos Emeralds, and that there was only one left to find. Knowing that the last Chaos Emerald was on Angel Island, Tails told Sonic where to find it and headed out with him.

Upon arriving on Angel Island, Tails and Sonic found Eggman demanding Knuckles to hand over the Chaos Emerald. Unfortunately, Eggman snatched the Emerald when Knuckles turned his attention to Sonic. Now possessing all the Chaos Emeralds, Eggman gloated to the heroes that he planned to harness the Emeralds' power to create the "Brainwash Beam", which would let him take over the world, before taking off. As Sonic and Knuckles started arguing over whose fault this was, Tails stopped them. Tails then figured that Eggman needed to head into space in order for the Brainwash Beam to cover the whole world. Believing that Eggman had a space station to launch a rocket from in South America, Tails headed there with his friends to stop Eggman. Unfortunately, they were too late, as Eggman had already prepared a rocket and was heading into space. Not willing to give up, Sonic asked Tails for a way to catch up to Eggman and Tails replied that it was possible using the space station's controls. Despite Tails being against this reckless plan, Sonic went through with it and caught up to Eggman.

After Sonic destroyed his space satellite containing the Brainwash Beam, Tails found Sonic after he crash-landed on Earth, and chided him for his recklessness. Since the Chaos Emeralds had been scattered all over the Earth after Eggman's space station exploded however, Sonic had to go out finding them. When Sonic returned, Tails learned that one Emerald was missing, which Knuckles figured was still in Eggman's possession. As such, Sonic went into space and got the Emerald back after defeating Eggman in a final confrontation. When Sonic later returned, Tails learned that Eggman had disappeared after his defeat, ready to plot his next move.

Sonic Jump (2012)
In Sonic Jump (2012), Tails and co. discovered that Eggman had begun kidnapping Animals again and taking them high into the sky, prompting the heroes to set out to stop Dr. Eggman's operations. Whenever they managed to corner Eggman in a Zone and defeat him however, the doctor would retreat to another Zone, although not before capturing more Animals. After Eggman's defeat in Mechanical Zone however, the doctor would crash down to Earth, ending his plans, thus allowing Tails to reunite with all the Animals.

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 down, 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 on board the Air Fleet after he fled the White House in Central City when it was overrun by the Black Arms, Tails got on board 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 and protecting the President's escape aircraft.

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 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 chasing 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 drove Sonic off.

A while afterward, 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 SS Marine by accident. With notes provided by Marine, though, Tails built 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 built the SS Tornado EX for him and Sonic to return home in. As they were taking off, Marine arrived in her SS Super-Marine 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 saw the symbol on Storm's Type-S and realized who they 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 MeteoTech, 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 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 afterward, 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 were 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 that trouble was up. When he caught Metal Sonic, though, Tails was forced to fight him briefly. Afterward, 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 Marauders' 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 helping 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.

In combat, Tails has low damage power and low armor, but he is quick enough to attack twice in each round. Tails relies on his team to protect him while he supports them with special abilities.

Sonic Unleashed
In Sonic Unleashed, when the Earth broke apart, Tails went to Apotos to gather data, hoping this and his friend Professor Pickle should shred some light on this global crisis. At nightfall, Tails was attacked by Dark Gaia's Minions, but was saved by Sonic the Werehog. Recognizing Sonic despite his new form, Tails heard Sonic and new friend Chip's story about how it was Eggman who shattered the Earth and gave Sonic his new form. Tails then took Sonic and Chip with him to Spagonia in his Tornado-1 to find Professor Pickle, but when they arrived they learned Eggman had kidnapped the professor.

Tails, Sonic and Chip tracked Pickle to Mazuri where they freed him from Eggman's base and reclaimed the stolen Gaia Manuscripts. Afterward, they learned from Pickle that an ancient creature named Dark Gaia was behind the world's shattering since it was not fully reborn, 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. After taking Sonic and Chip to Eggmanland where the last Gaia Temple was, Tails 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 attacked 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 the Wisp incident, Tails attended and helped prepare Sonic's surprise birthday party. After Sonic arrived, Tails gave Sonic a birthday chili dog, just as 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 Classic Sonic, Sonic's past self from another dimension, but believed him to be his Sonic (named Modern Sonic). While Modern and Classic Sonic passed through a Boss Gate, Tails met his own counterpart, named Classic Tails, as well. By the time 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, that 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 time-space counterpart, Classic Eggman, revealed themselves as the ones behind the Time Eater in an attempt to erase the Sonics from history so that the doctors would be victorious in the present. When the Sonics were knocked out by the Time Eater, however, the Tails' and their friends cheered them on, allowing them both to transform into Super Sonics. When the Sonics defeated the Time Eater, the Tails' and their friends were sent back to Modern Sonic's world and their party. During the party, once the time came for Classic Tails and Classic Sonic to return to their world through a Time Hole left behind by the Time Eater, 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 the Animals they had caught. When Eggman dropped a Capsule with Animals, Tails and Sonic went after it, until the Tornado's wing was shot by Eggman. As they fell, Tails and Sonic stumbled upon the Lost Hex. Landing there, Tails would repair the Tornado while Sonic investigated the area. Once he was done, he and Sonic went to find Eggman and his newest allies, the Deadly Six.

Eventually, Tails and Sonic found Eggman scolding the Deadly Six. Though Tails tried warning Sonic not to touch the conch Eggman used to control the Deadly Six with after examining it, Sonic knocked it away, causing the Deadly Six to rebel against Eggman by taking control of his Badniks and having them attack everyone. In the skirmish, Tails was injured. prompting Sonic to take him to safety as he fled with Eggman and his lackeys.

After escaping, Tails and Sonic left Eggman and his lackeys to stop the Deadly Six. In the meantime, he and Sonic were contacted by Amy, who informed them that something was sucking the world of life. Reuniting with Eggman, the doctor revealed the Deadly Six were using his Extractor to destroy the Earth. The parties thus teamed to stop the Deadly Six, planning to get Eggman through the Zeti so he could shut the Extractor down properly.

On the way, Tails grew resentful at Sonic for entrusting Eggman to stop the Extractor rather than him. The group was soon after briefly contacted by Zavok, who stated the futility of their actions, but they continued on no less. In the meantime, Tails tried repairing 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, though he still got scolded by Sonic.

The group later stumbled upon a Capsule. Discovering it was a trap set by the Deadly Six, Tails saved Sonic from it when he tried to open it, though he got caught in it himself and teleported to the Deadly Six, who had planned to capture Sonic. While in their captivity, Tails was nearly roboticized by Zavok to be used as a weapon against Sonic, but Tails used one of his twin-tails to stop the Roboticizer. Disguising himself, Tails tricked the Deadly Six into thinking he had become their slave. Then, when he was sent to kill Sonic, Tails attacked Zavok, Zeena, and Zor by surprise, enabling Sonic to finish them.

With the Zeti beaten, Tails and Sonic reached the Extractor only find it turned off. Eggman then showed up in a new mech, having faked his death earlier so that he could charge his mech while Sonic fought the Deadly Six, planning to conquer the remains of the world. After Sonic beat 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 in the meantime, Tails and Sonic returned to Amy and Knuckles on Earth, where Tails saw Sonic take a nap to rest from their ordeal.

Sonic Runners
In Sonic Runners, Tails and his team discovered that Dr. Eggman was back to sow up chaos again. With the aid of Sonic and Knuckles, Tails spent the next period foiling Eggman and his lackeys' numerous plots, such as kidnaping Animals, hunting Wisps on Earth, harassing Chao, building new and improved Badnik armies, and attempting to procure the Master Emerald. Tails in particular contributed with technological knowhow. Along the way, Tails also helped several local inhabitants with their issues.

While Team Sonic managed to stop Eggman every times, it all would lead to Eggman's endgame: the construction of a new Brainwashing Laser powered by the Chaos Emeralds to enslave the world with. Although Tails and co. secured the Emeralds, they were too late to stop Eggman from draining them of their chaos energy. In the end, it came down to a final showdown between Team Sonic and Eggman, during which Eggman fired his Brainwashing Laser at Sonic. However, thanks to the Chaos Emeralds Sonic had, which reabsorbed their power from the laser, Sonic transformed into Super Sonic instead, and Tails saw him take out Eggman's laser. Reuniting with Sonic in the aftermath, Tails noticed Eggman had snuck away to plan his next scheme, but took solace in his friends' assurance that they could stop any of Eggman's schemes, and went to celebrate with them.

Sonic Runners Adventure
In Sonic Runners Adventure, Tails was on South Island when he somehow got caught by Dr. Eggman, who forced him to build him a robot teleporter. Eventually, Tails got a transmission out to Sonic, who soon came and rescued him from Eggman's facility. After Tails brought Sonic up to speed, the began a hunt for the egg-shaped scientist. They would eventually follow Eggman through Tails' teleporter, only for Sonic to get injured during the transfer. Leaving Sonic to rest, Tails began looking for Eggman on his own. After shutting down a stronghold for Eggman's Badniks, Tails regrouped with Sonic. Locating Eggman soon after, Tails defeating the doctor battle, only for the latter to escape again.

With Knuckles coming along, Tails and Sonic let the echidna take the lead when they arrived in more hostile surroundings. Along the way, Knuckles took out Eggman's newest Extractor after Tails did some recon. Tails and his team would then follow Eggman to Sky Sanctuary. When Sonic was forced to let Eggman go by the doctor's Mind Control Ray though, Tails and Knuckles realized what Eggman's plan was all along: setting up a new mind control canon powered by the Extractor and Sky Sanctuary to take over the world with (which was also how Eggman caught Tails). Despite the odds though, Team Sonic still managed to destroy Eggman's mind control cannon while Sonic forced Eggman to retreat.

Sonic Forces
In Sonic Forces, Tails sent a distress signal to Sonic notifying him that Dr. Eggman and his forces were attacking the City. He, alongside some civilians, were then saved by Sonic from some Egg Pawns. However, after Tails had the others escape to safety through a nearby alleyway, he bore witness to the arrival of a mysterious warrior named Infinite, as well as what appeared to be Zavok, Chaos, Metal Sonic, and Shadow. Tails initially thought Infinite was faster than Sonic when the former managed to dodge the hedgehog effortlessly, although he soon realized it was something else and tried to use the Miles Electric on Infinite. However, the readings it gave did not make any sense. As such, Tails could only watch as Sonic got defeated by Infinite and his gang, and taken away.

With Sonic defeated, the Eggman Army quickly took over. Within months, all but a few isolated areas in the world were under their control. Meanwhile, the world's population, including Tails, believed Sonic to be dead. Although Tails' friends banded together to form the Resistance in an effort to continue the fight against the Eggman Empire, the group was unable to recruit Tails himself.

Six months after Sonic's disappearance, Tails was in the City, attempting to fix a broken E-123 Omega, only for Chaos to ambush him. As Tails broke down and begged for Sonic's help, Classic Sonic arrived via a portal and dispatched Chaos. Recognizing Classic Sonic, Tails correctly deduced that Classic Sonic's arrival was the result of the new power Eggman was using to conquer the world. Surmising that fate had ensured that a Sonic would be there to stop Eggman, Tails teamed up with Classic Sonic to defeat Eggman and end the War to Take Back the Planet, while also searching for a way to get Classic Sonic home.

Talis and Classic Sonic eventually found Eggman in Green Hill, and after eavesdropping on Infinite and Eggman, learned not only about the existence of the Phantom Ruby prototypes, but also that Sonic was still alive. After Infinite took his leave, Classic Sonic proceeded to fight Eggman. After Classic Sonic defeated Eggman, Tails celebrated with his friend, only for the doctor to reveal that in three days, he was going to eliminate the entire Resistance. Tails attempted to inquire about Eggman's plan, but the latter refused and took his leave. Undaunted, Tails and Classic Sonic went to Mystic Jungle, which Eggman had mentioned was the last place Sonic was seen, so they could tell Sonic of Eggman's plan. Although they were not able to find him, they did find a new member of the Resistance, who took them to the Resistance HQ where Tails was reunited with Sonic. There, Tails told them of Eggman's plan to eliminate them.

When Knuckles came up with Operation Big Wave to take Metropolis, Tails was in favor of it. Unfortunately, the attack was thwarted by Infinite, who used his Phantom Ruby-derived powers to wipe out over 80% of the Resistance's army. After the army withdrew, the Resistance agreed that they had to figure out the secret behind the Phantom Ruby. When Rouge found a lead at the Chemical Plant, Tails and Classic Sonic went there to check it out. There, Tails discovered that the Phantom Ruby needed a huge amount of energy to work, energy which only could be provided by Eggman's newly-rebuilt Death Egg. With their next move being to destroy the Death Egg, Tails came up with a plan that allowed the Resistance to destroy the Death Egg.

With the Phantom Ruby seemingly out of commission, Tails and the Resistance attacked Metropolis a second time in an attempt to capture Eggman and end the war. When Tails and Sonic found Eggman however, the doctor called in Infinite, who still had his powers. On Eggman's order, Infinite opened a portal into Null Space, a close-up space designed to trap Sonic inside it forever. Although Tails managed to stay safe, Sonic and the Avatar ended up being pulled into null space. Tails, confused about why the Phantom Ruby was still working, was then told by a gloating Eggman that he had a backup reactor for the Phantom Ruby ready underneath the Eggman Empire Fortress. Luckily for Tails, Sonic and the Avatar soon found a way out of null space while the Resistance managed to capture Metropolis.

Having less than an hour left before Eggman's endgame, Tails and the Resistance confronted the Eggman Army at the Eggman Empire Fortress in an attempt to reach and stop the Phantom Ruby's power source. During the fight, E-123 Omega came to the aid of Tails and co. It was then that Eggman had Infinite execute his endgame; using his Phantom Ruby prototype's power, Infinite created a sun to drop on the Resistance. During the chaos however, Tails noticed that the Avatar was in possession of a Phantom Ruby prototype. Seeing that the Avatar could call upon its power, Tails figured they could neutralize Infinite's sun with it. After the Avatar pulled this grueling task off in the last possible moment, Tails went after them and helped them back on their feet. Tails and Classic Sonic soon after met up with Sonic and the Avatar after following the latter duo's succesful mission to destroy the Phantom Ruby's backup reactor. However, Eggman then revealed that the reactor was a decoy and that the real Phantom Ruby had been incorporated into his triumph card: the Death Egg Robot. This meant the Ruby had no weakness anymore. With the Eggman Army on the rise thanks to the Ruby, Tails saw Sonic, Classic Sonic and the Avatar destroy the robot, which ensured the Resistance's victory over the Eggman Empire.

In the aftermath, Tails bid farewell to Classic Sonic, whose return to his dimension was imminent with the Phantom Ruby gone. Although Tails was sad to see him go, he received some comfort from Sonic, who inspired the Resistance to set out and clean up the mess Eggman had left the world in. Some time later, the Resistance disbanded after a meeting in the HQ. There, Tails made a speech about that even though they were going back to their old lives, they would be friends forever and keep working together to restore the world, something which they all agreed on.

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 technique. There is no gameplay mode in which Tails follows Sonic. Also, the player is unable to collect trophies/achievements while playing as Tails.

Sonic the Hedgehog Spinball
In Sonic the Hedgehog Spinball, Tails and Sonic discovered that Dr. Robotnik had taken control of Mount Mobius on Planet Mobius. On this mountain, the doctor had created the Veg-O-Fortress, a fiendish contraption powered by the mountain's volcano, which was robotizing Animals at an incredibly fast rate. Seeking to stop Robotnik, Tails and Sonic mounted an air assault on the fortress, only to be blasted in mid-fight by Robotnik's cannons. While Tails got away in his and Sonic's aircraft, Sonic got knocked into the deep waters around the fortress. Eventually though, Tails returned in time to save Sonic when he fell down from space, after ensuring the Veg-O-Fortress's destruction and defeating Robotnik.

In the game, Tails is a non-playable character, only appearing during the opening and ending cutscenes.

Sonic Drift
In Sonic Drift, Tails is one of the four playable characters in the game. His vehicle in this title is the MTP-01 Wheelwind.

In gameplay, Tails is the most balanced of the four racers; he possesses good cornering but low maximum speed. On the race track, Tails' special ability is to literally send his kart flying into the air for about three seconds (like when hitting a Jump Spring), 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 is best to maneuver back over to the track.

Sonic Drift 2
In Sonic Drift 2, Tails is one of the seven playable characters in the game. His vehicle in this title is the MTP-02 Wheelwind S7.

In gameplay, Tails is once again the most balanced of all the racers, possessing no strength or weaknesses. On the race track, Tails' special ability is the "Jump", the ability to literally send his kart flying into the air (like when hitting a Spring or using a Jump), but for about five seconds instead of three like in Sonic Drift.

Knuckles' Chaotix
In Knuckles' Chaotix, Tails and Sonic made a cameo appearance during the good ending cutscene, where they can be seen flying by in the Tornado.

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.
