Sonic Advance 3 Ending

Tails with some of his closest friends.

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[]


Tails and Sonic are best friends.

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.[1][2] 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 somewhat 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 devastated at Infinite's presumed murder of Sonic, with Silver even claiming that he "lost it" after Sonic's presumed death (although in the Japanese version, it is instead stated that Tails went missing) 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[]

Tails and Amy, Sonic Adventure 2'

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

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).


Tails with Dr. Eggman and Amy.

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[]


Tails and Shadow in the Circus Park.

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.[3][4]

Wave the Swallow[]

Tails and Wave (Sonic Free Riders Opening)

Tails and Wave.

Wave the Swallow and Tails are rivals as inventors since they both are mechanical geniuses. 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 how he reacted, going so far as suggesting to kiss him should he lose their initial fight. 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[]

But why would Eggman's robot attack Eggman?
―Tails, Sonic Heroes.

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.

Hmm, that should've done it... I couldn't figure it out for you, buddy. I'm sorry I wasn't smart enough.
―Tails, Sonic Forces.

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[]

Tails and Marine.

Marine the Raccoon is a good friend of Tails from Blaze's world, as they quickly befriended each other soon after meeting. Tails was a valuable ally to Marine, as he helped her build 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 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 in Tails. Despite this, Tails was willing to endure Marine's antics, 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. After Marine later matures and stops commanding Tails however, they made up. When Tails later went home with Sonic, Marine earned his respect with her newfound maturity and told him how he and Sonic were the best friends ever.[5] She thus vowed to meet him again no matter what, though she could not help crying over his departure.

Classic Sonic[]

It's like the world needs a Sonic... any Sonic, to keep things in balance.
―Tails, Sonic Forces

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 parting with Classic Sonic.

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.
