Miles "Tails" Prower

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

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

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

A contest was held at STI in which Yasushi Yamaguchi, originally the main artist and zone designer for Sega's Sonic Team, won. The character was meant to hold a "deep admiration for Sonic."

The name 'Miles Prower' is a play by play word on a measurement of speed (miles per hour). The character was originally intended to be a tanuki (a raccoon-like canine native to East Asia and extremely popular in Japanese folklore), who had been modeled after a UFO catcher plushie. The designers decided to change him to a fox however to avoid possible comparisons to Mario who at the time had a power up called the Tanooki Suit. This suit allowed him to fly and made him look like a tanuki, hence the name of the power-up. Lastly, Tails received his twin-tails to grow more of a personality. Yamaguchi's entry won but Sonic Team decided to change his character's name from "Miles" to "Tails" in which Yamaguchi was not too pleased with at all about. The team and Yamaguchi ended up with a compromise: he settled the name "Miles" in as his legal name; "Tails" would be his nickname, ending up with the full name of Miles "Tails" Prower.

During the design process, Tails was originally going to have completely black pupils and only a single tail. Yasushi Yamaguchi also created Tails with the image of him being five years old, despite his official age ending up being eight. Despite Tails' three bangs are usually depicted erupting from the middle of his head, his creator intended them to be coming from the right side.

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

Tails was redesigned (along with the rest of the Sonic cast of characters) by Yuji Uekawa for Sonic Adventure. Tails' redesign saw him having his fur color changed to an amber like color, gained visible blue irises, became slightly slimmer and received a small boost in height. He shifted to a more streamlined appearance with rounded ears at the tips as well as longer tails which are used as his main form of attack, most notably the Tail Swipe. Later on, between Shadow the Hedgehog and Sonic Unleashed, he was made even taller and receiving a few scratches on the front of his shoes.

Appearance
Tails is a young, anthropomorphic fox cub with a unique genetic mutation giving him two tails instead of one. He has mostly yellow-orange fur with white fur around his muzzle, front torso, and the tips of his tails. He also has blue eyes, triangular ears with white canals and three locks of hair on his forehead. Typically, his attire consists simply of white gloves, and shoes that are red from the heel to the middle, and white from the middle to the toe with gray soles.

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

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

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

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

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

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

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

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

Powers and abilities
Though not as much on the forefront in battles as other characters, Tails is still an accomplished fighter. On his own, he has defeated several of Dr. Eggman robots and combat mechs, and even single-handedly defeated the entire Battle Bird Armada and Witchcart's gang. Once, he was also able to go head-to-head with Knuckles the Echidna.

Due to a genetic abnormality, Tails is bequeathed with two large, fluffy tails that can twirl together. Over time, Tails has learned to use them to his advantage in many situations. Most noticeably, Tails can spin his twin-tails like rotary blades to fly or hover like a helicopter. While in flight, Tails can move around with outstanding agility and enough speed to keep up with even Sonic, who can run 768 mph at average. However, he gets fatigued if he uses them to stay in flight for too long.

By manipulating the curvature of his twin-tails, Tails can glide through midair. He can also use his twin-tails as a rear turbine to sail across the ground at speeds great enough to let him stand a chance against Sonic in a race. By using them in said manner underwater, Tails' twin-tails become rear propellers that let him move around underwater with ease. Tails' twin-tails are also quite powerful limbs, being both strong and fast enough to slice through metal, and highly prehensile, having once grabbed a toothpick from a sandwich by their tip and then used it to type on a keyboard.

Even without his twin-tails, Tails can move at exceptionally high speeds. He is able to keep up with Sonic's speed on foot and even once cut Sonic off repeatedly using extremely swift movements. With or without his twin-tails though, Tails' speed still is considered average by comparison and he has admitted in spite of his feats that he is still slower than Sonic. Tails is also quite physically strong, having enough strength to hold up both Sonic and Knuckles at once and move blocks that supposedly weights several tons. He is also tough enough to go through atmospheric reentry and then land on the ground unharmed. In addition, Tails has demonstrated great feats of acrobatic skills and agility, he can effortlessly grind on rails and pull off different acrobatic tricks while airborne. He is also good at swimming.

Tails has also demonstrated the ability to harness chaos energy for his own use, although this is an ability he uses sparingly. By harnessing the Chaos Emeralds, Tails can give himself a boost in power.

Tails possesses a genius-level intellect and is a skilled inventor. Described as a mechanical genius and a natural prodigy in this field, Tails is as talented as Dr. Eggman, who has an IQ of 300. Tails even once claimed he is smart enough to build a TV out of paperclips and reprogram a supercomputer using a toothpick and dishwashing detergent. As a testament to his skills, when presented with foreign technology (even of the advanced kind), Tails only needs to take a few looks to understand it. He is likewise quick to grasp new forms of technology, and once he develops an understanding of it, he excels at said technology. Tails also has a knack for building things, to the point that his friends believe that there is nothing he cannot built. Over time, Tails has created a number of inventions that often have gotten both him and Sonic out of trouble and let them stay just ahead of Eggman's schemes. These creations include his transformable Tornado series of airplanes, his combat equipment, his Emerald Detector, the Sea Fox, the Lunar Fox, a fake Chaos Emerald and his multifunctional Miles Electric to name a few. Among the different fields of his expertise, Tails is also a capable Extreme Gear mechanic who can create, customize and tune Gears. Though he is Wave the Swallow's lesser as an Extreme Gear mechanic, his skills are still good enough to impress Wave, which is a considerable feat.

While mechanics are his specialty, Tails is also well-versed in physics and science, enough to come up with solid theories regarding matters as complex as time and space. Combined with his mechanical skills, Tails can construct different vessels that can travel between dimensions. In addition, Tails has shown that he can read and translate Binary and Hexadecimal language. He is also a history buff who knows a lot about his world and its lore.

In direct combat, Tails lacks his friends' raw hand-to-hand combat skills, and focuses more on tactics and providing support to his allies. On the occasion where he is fighting on his own however, Tails utilizes a fighting style that combines a blend of basic punches and/or swipes with his twin-tails. When applied in battle, his twin-tails become like whips that can lash out with significant power across a wide range. Tails can as well spin around with his twin-tails at high speeds to becoms a dangerous top that can tear through opponents. Tails also has a number of aerial maneuvers to get advantage over ground-bound opponents. These maneuvers let him launch attacks at foes from above or fly at them with increased momentum. Tails can also perform the Spin Attack, where he curls tightly into a concussive ball or cutting disk, while in locomotion to damage, mow down, or burrow through obstacles and foes, and any substance if given enough speed. Using the Spin Jump, Tails can leap into the air and curl in a spinning ball to deal damage to anything he lands on. The Spin Dash lets him shoot himself as an acceleration roll at high speeds to break barriers or mow down enemies. The Homing Attack allows Tails to jump and home in on an enemy to attack. During some of his tougher periods of battles, Tails has also been known to complement his fighting style with gadgets.

Tails has excellent skills when it comes to piloting aircrafts and driving vehicles, including mechs and racecars. He also has incredible aerial dogfighting skills, being able to win areal battles against massive ships like the Egg Carrier and Egg Cauldron with his personalized biplanes. Tails is also a talented Extreme Gear rider in his own right, and possibly one of the best in the world due to his ability to go head-to-head with the Babylon Rogues, who are considered the best Extreme Gear riders around. On an Extreme Gear, he has enough skills to ride through mid-air with great control.

Equipment and weapons
As shown on several occasions, Tails tends to make use of various mechanical devices to improve his battle prowess, such as his Magic Hand, Energy Cannon and Big Hand. He also occasionally carries around a wide arsenal of bombs, from basic explosives, to remote-controlled mines, to Flash Bang grenades. He also has equipment for support, like healing devices, bots for fortifying his defenses and the Helmet. Another example is his Cyclone mech, which he used to combat G.U.N.'s forces during the Shadow incident.

Once, Tails made use of the Ring Boomerang, which could pull and latch onto objects like a grappling hook. On a few occasions, he has also used Dummy Rings as projectile weaponry.

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

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

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

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

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

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

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

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

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

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

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

Super Tails
By using all seven Super Emeralds, or later the seven Chaos Emeralds, Tails can enter a Super State, transforming him into Super Tails. In this state, all of Tails' abilities far surpasses his normal ones. He is also able to fly without his twin-tails, and is nearly invulnerable. However, this transformation consumes a lot of energy and requires Rings to be maintained.

Color Powers
By harnessing different variants of Hyper-go-on from Wisps, Tails can use specific Color Powers to transform into a certain form, such as a drill, a laser or even a planet, each one possessing its own unique abilities. So far, Tails has been able to transform into the Cyan Laser, Yellow Drill, and Indigo Asteroid. However, these transformations require a steady supply of Hyper-go-on to be maintained.

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

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

One of Tails' bigger weaknesses is his meekness towards women. He is easily flustered, something typically attributed to his young age. This allows him to be easily manipulated by Amy's overzealousness or Rouge's flirtatious nature should they want his help.

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

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

Sonic the Hedgehog
Sonic the Hedgehog is Tails' best friend, as the two have been inseparable since they first met shortly before the events of Sonic the Hedgehog 2. On Westside Island, Tails saw Sonic running at incredibly high speeds. He was impressed by the cool blue hedgehog and began to follow. Sonic eventually stopped and the two became close friends. He began to hang out around Sonic at all times of the day, catching up with him using his two tails. Eventually, Tails spotted Sonic's Tornado plane, which he grew fond of and is usually seen borrowing it. Sonic usually treats Tails as the "younger brother" that he never had.

Sonic and Tails were always there to help each other, their friendship growing until they had a more brotherly relationship. It is often Tails who creates machines for Sonic in his help and also made him three Extreme Gears. In Sonic Advance 3, they are known as the "Unbreakable Bond" when they team up. Together, they have proven themselves a near-perfect duo; both provides strengths to the other's weaknesses (Tails provides the smarts while Sonic handles the muscle), and they have demonstrated profound teamwork in combat. In Sonic Rivals 2 it is shown that Sonic trains Tails to learn how to run and fight in their free time. Whenever Sonic has an adventure, he always comes to Tails and asks him to come along and Tails is always ready to help. Tails also used to depend on Sonic a lot, but later realized that he cannot depend on him forever. Sonic is also an idol to Tails, and Tails just wants to be as heroic as he is.

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

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

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

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

In Sonic Forces, Tails was left horrified at Infinite's presumed murder of Sonic, with Silver even claiming that he "lost it" after Sonic's presumed death when explaining why he was absent from the Resistance six months later. In addition, when Chaos (or, rather, his replica) attempted to kill Tails in an ambush in the City while he attempted to fix up Omega, Tails proceeded to break down and beg for Sonic's help. However, he regained some bits of his original self when Classic Sonic arrived, and was later overjoyed when he saw that Modern Sonic was still alive.

Amy Rose
For the most part, Amy Rose and Tails have a friendly relationship with each other.

Both Amy and Tails are usually together when they and Sonic are out saving the world, although Sonic uses Tails to distract Amy in order to escape from her or avoid contact during a mission. Tails usually responds to this with a lack of confidence as he too is not a fan of her anger.

Amy also at times will come to Tails' aid and defend him, like when Wave the Swallow insulted Tails, where Amy got infuriated whilst challenging Wave to a race. Tails has also saved Amy numerous times when Sonic could not, to which she is very grateful. In Sonic Adventure, when the Egg Carrier was losing altitude and about to crash, Sonic told Tails to act quickly and take Amy to safety. Tails also saved Amy a few more times from Dr. Eggman in the sequel, saving Amy along with Sonic from the exploding Prison Island, and also rescuing Amy when Eggman had her at gunpoint on the Space Colony ARK.

Knuckles the Echidna


Tails is close friends with Knuckles the Echidna. Although they do not seem to have much of a relationship early on, when they first met, Tails and Knuckles were enemies, as Dr. Robotnik had tricked the echidna into believing Tails and Sonic were intruders seeking the Master Emerald for evil purposes, though they become friends later on when Knuckles discovers that Robotnik had lied to him. Tails interact more than Knuckles as does with Sonic, and while the two do not see each other as rivals, Tails does occasionally tend to irritate Knuckles with his technobabble, albeit this is not intentional. Likewise, Knuckles seems to enjoy teasing Tails from time to time, such as when he scares Tails with the idea that they fought with Shadow's ghost just before Hang Castle Zone in Sonic Heroes. Despite this, Knuckles is likely Tails' best friend after Sonic, and the two have teamed up on numerous occasions through the series.

Knuckles has shown that he cares for Tails, such as when he assured Tails that Dr. Eggman is nothing to worry about when they join Sonic at the start of their story in Sonic Heroes, or when he furiously defended Tails after Wave the Swallow  mocked Tails in Sonic Riders.

Even though they are good friends, Tails and Knuckles have fought each other in the past, usually when Knuckles has been tricked by Eggman, but in the end, there are never any hard feelings between them.

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

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

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

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

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

In Sonic Forces, Tails retained some of the rivalry with Eggman. During the latter's boss fight, he makes some barbed comments regarding Eggman's qualities as a scientist, or failings within, such as claiming that Eggman's "underestimation" of his expectations meant that Eggman actually failed, and later after the Avatar undid Eggman's ultimate plan via a prototype Phantom Ruby, Tails told him that a good scientist always "checks and double-checks" their work.

Shadow the Hedgehog
Shadow the Hedgehog and Tails were at first enemies in Sonic Adventure 2 because Shadow was impersonating Sonic and got him thrown in jail at Prison Island. Towards the end of the game, they became allies when they had to save the planet from the Space Colony ARK. For the most part Tails and Shadow's relationship seems to depend on their goals.

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

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

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

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

In Sonic Adventure 2, Tails was basically unaware of Rouge's presence, but this was because Rouge was sent by Eggman to spy on Tails when he was trying to find the President. After that their interaction stopped until the Ark was set on its collision course with earth. In Sonic Battle, Rouge would use her charm to tease Tails because she thought it was cute and funny how he reacted. She was however very helpful in Tails' story as she gave him the access card for the Central Computer Room, distracted Shadow, and told Tails how to escape the Guard Robos. Later on in Rouge's story Tails had to stop Rouge from stealing a Chaos Emerald. In Sonic Chronicles: The Dark Brotherhood, while in Metropolis, Rouge would sometimes be snarky with the plans Tails and Eggman would come up with but still show a playful affection for Tails. In Sonic Free Riders, Tails was disgusted with Rouge's selfishness and unsympathetic behavior towards her teammate E-10000B.

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

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

In the Mario & Sonic series handheld versions, they seem to be friendly as well. In the London version, after the Phantasmal Fog clones try to attack Cream, Tails assures her she'll be safe while Mario, Sonic, and Luigi hold them back. He then lashes out at the clones for trying to attack her. In the Rio version, they are partners for Beach Volleyball on day 2 of Mario's Story. Cream states that they have "the bestest teamwork."

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

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

Tails also attempted to repair Omega inside the City in Sonic Forces, although the damage Infinite inflicted on the robot was such that not even Tails was able to repair him, causing him to apologize to Omega's lifeless shell.

Marine the Raccoon
Marine the Raccoon is a good friend of Tails from Blaze's world, as they quickly befriended each other soon after meeting. Tails was valuable ally to Marine, as he helped her built ships so she could go on adventures. When Marine declared herself captain, she made Tails her assistant, though Tails never agreed to it. Just like Sonic, Tails was likewise genuinely annoyed by Marine's antics, her bossy behavior, and the way she insisted that he followed her orders. While Marine is amazed at Tails' intellect, she often ignored his warnings and told him he was no fun. Marine's reckless and careless behavior also tended to spark frustrations to Tails. Despite this, Tails was willing to endure it, but her behavior always made him worry.

When it was revealed that Tails thought she was a nuisance, Marine felt betrayed and called him stupid. However, Tails half-heartedly told Blaze that she was harsh to make Marine cry. When Marine matures, and stops commanding Tails, they made up. When Tails then went home with Sonic, Marine earned his respect with her newfound maturity and told him how he was the best friend ever. She thus vowed to meet him again no matter what, though she could not help crying over his departure.

Classic Sonic
Tails and Classic Sonic first met during the Time Eater incident, although Tails initially mistook him for his own Sonic during their first encounter. After sorting out who was who, Tails teamed up with Classic Sonic, alongside his other allies, to stop the Time Eater.

Tails met Classic Sonic again during the War to Take Back the Planet. After Classic Sonic had saved him from a Chaos replica, they teamed up to save the world and to help Classic Sonic get back home. Although Tails reunited with Sonic, Tails and Classic Sonic remained as close as ever, with Tails appreciating every effort Classic Sonic made to help the Resistance. When it was time for Classic Sonic to return home, he bid farewell to him with a fist bump, leaving Tails sad to see his friend leave.
