Tails the Fox (Hide And Seek)

Tails is communicating with Sonic as he runs through Green Hill Zone at the beginning of the game, but after he cuts out (due to being possessed by Exeller, unbeknownst to Tails), he panics and flies to the zone in his biplane, the Tornado, to make sure Sonic is alright. When he lands, he is slowly horrified to find hundreds of dead Animals littering the field, with the bodies being displayed in more gruesome ways and growing in number. He finds "Sonic" eventually, but is nervous about it. He approaches Sonic only to find that he has blood on his hands. Tails chooses to either leave Sonic or go with him (or survive if having the Green Ring). Unbeknownst to Tails, Sonic is watching helplessly and is relieved that Tails leaves the area.

Tails is sent to a nightmarish version of Angel Island where he is relentlessly hunted down by Exeller. He is forced to run through a burning rainforest as creepy images of Sonic.exe flash before his eyes mocking him, and if he survives that he has to hide from Exeller as he hunts him through a deep cavern. Should Tails survive that, however, he will manage to escape by jumping into a Warp Ring that takes him to the Hidden Palace Zone. There, Tails reaches the Master Emerald, meeting up with Knuckles and/or Doctor Robotnik if they survived as well.

In the worst ending, Tails.exe appears alongside Knuckles.exe and Robotnik.exe in the Game Over screen. After the short poem, the credits show Tails walking through a now-corrupted Green Hill with Knuckles and Robotnik. He can be seen with Exeller on Mountain Peak in the post-credits scene, where he tells Tails that he is unsatisfied, and resets the timeline to give him and everyone another chance.

In his solo ending, The Master Emerald shows Tails that Sonic is possessed, and he decides to return to Green Hill to get the Tornado and warn Amy, Cream and Sally. However, he finds the plane in pieces, with Exeller pinning him to the ground before he can react. Tails growls that even if he dies Knuckles will stop him, but after Exeller reveals the deaths of Knuckles and Robotnik his head is stomped into paste, killing him. Tails will be saved if he has a Black Ring, however, and escapes. As he sadly walks through Green Hill again, seeing the souls of the Animal Buddies playing as Knuckles and Robotnik's souls run alongside him. Tails starts to lose hope, but refuses to give up and is dropped into a nightmarish version of the zone where Exeller chases after him. Tails manages to escape, ending up in the Blood Temple from the Nightmare Version dimension after entering a corrupted Super Ring, and meets himself from that dimension. Tails discovers the knowledge of alternate dimensions and timelines, and his demonized counterpart shows him another corrupted Warp Ring that leads out. Tails is reminded to collect green and black rings as he walks through.

In the Tails & Knuckles duo ending, the two head to Mecha Green Hill Zone, where they plan to distract him and free Sonic. This however backfires as Tails is thrown into an illusion, forcing the two to escape once more, and Tails leaving or saving Sonic. They are killed off-screen regardless.

In the Tails & Eggman duo ending, the two decide to head to Metropolis Zone, since the area is known for its deadly traps and obstacles. Eggman tells Tails to head through a door, though miscommunication gets them separated, and matters only get worse as the lights black out with Exeller arriving on the spot. Tails however manages to get through Exeller and to Eggman. Robotnik does not know how to break the news to Tails, and tells him he was not able to free Sonic from his possession. Tails is visibly upset at Eggman, and scolds him off for it, but decides to teleport to Mountain Peak. He agrees to help Eggman, but only if they can save Sonic.

Exeller summons Tails.exe to Spring Yard Zone to help him kill Knuckles and Robotnik, and appears in an unused boss fight accessible through the level select. If Knuckles dies in his boss fight, Tails will resist Exeller's control and teleport Robotnik to Mountain Peak, resulting in Robotnik's Solo Ending.

In the best ending, Tails makes it first to the Master Emerald, Knuckles and Eggman both arrive, and all see Sonic's reason for killing (being possessed by Exeller). The three confront Exeller and fight off a "giant version" of him. Tails decides to save Knuckles after he is ambushed, and defeats the giant. Tails is then given a choice to save Sonic after he breaks free from possession for a moment. Should Tails save Sonic, he will be saved by Knuckles, and the remaining duo are killed by an angry Knuckles while Tails cries. Should Tails leave (and save the group) they will proceed forward to the game's next events.

Sally.exe: The Whisper of Soul After the previous game's best ending, Tails is on Mountain Peak with Knuckles and Robotnik watching the view. The dialogue from said ending carries out as before. Though there are different outcomes depending on if Amy or Cream survived in the early-game.

If Amy and/or Cream are dead, Exeller arrives on Mountain Peak along with the corrupted girls. Tails panics and comments that this cannot be happening as Exeller leaves to hunt Sally and the girls prepare to attack. A choice screen will then pop up with Tails, Knuckles and Robotnik - if Tails is selected, Knuckles will throw him to safety before the girl(s) kill him and Robotnik. If Amy and Cream are both present, Tails attempts to defend himself with a black ring, but is killed after Amy throws her hammer, the weapon lodging itself in his head. Otherwise, Tails must defeat Amy or Cream in a boss fight before Alice teleports him to safety. If Amy and Cream are both alive, however, all of them will die, while Tails attempts to use a blue ring, but fails after learning it only works against duplicates. Tails' soul appears among the souls of Exeller's victims.

If he has survived either way, Tails is teleported to Forest Night Zone by Alice, where he laments the deaths of Knuckles and Robotnik and moans that they will just be trapped in an endless time loop forever. He considers giving up, but overhears Execun commenting to Exebark that they've found dinner. Tails hides in the bush and sees that Execun and Exebark have cornered Exebi. He then watches as Exeller arrives, telling Execun and Exebark off for trying to kill one of his most important slaves and for trying to kill the victims instead of toying with them. When they leave, Tails is grabbed via telekinesis and dragged out of his hiding spot, with Exeller informing him of his immortality and ability to make clones, revealing that he never really defeated him in Sky Sanctuary (secretly being Exebi). Tails then gets pushed to the ground as Exeller continues to mock him, and then realizes that if he pushes his buttons right he can make him go insane. When Exeller leaves, Tails comments that the situation is crazy, and that he needs to get to Freedom City to find help. He then heads into Volcano Valley and begins making his way through the zone to reach the city.

As Tails explores Volcano Valley, he is caught by Exeller, who grabs him and flies through a blizzard before dropping him into Silent Hill. Knowing that Exeller wants to play with him and that he cannot escape if he was caught so easily, Tails sadly makes his way through the snowing husk of the former Green Hill as memories of the good times he had with Knuckles, Sonic, Robotnik, Amy, Cream and Sally surround him. Eventually, Tails feels tired and passes out... Tails is thrown into an illusion and tries to make his way out of the environment while avoiding several illusions of his dead corrupted friends. Tails starts to get more nervous, but is nearly thrown over the edge when he sees illusions of Sonic and Amy. Killing both of them, he runs further and encounters further illusions of his other dead friends (Amy, Cream, Knuckles, Robotnik, and even Alice and himself!). He makes it out, but not before being caught by Exeller posing as a horrifyingly insane Sonic. Tails however, catches onto this, which annoys Exeller as they have made it to the main tower. They prepare to battle, but the timeline is reset before they could battle any further.

In the Tails and Amy ending, the two meet after Tails saves her from a now-corrupted Cream. The two begin to walk after the events, and tell their sides of what happened to each of them. Tails notes that Amy has aged significantly after using Sally's machine. The two then talk about who Exeller is and what he wanted, including the effects of "deja vu". Tails dashes through the frozen lake of Aqua Lake, and makes it to Rotor, who stops them after receiving orders from "Sally". Luckily Tails is able to convince Rotor that it is them, and he cuts his hand to prove that they cannot regenerate. They are let in, but not before being met by an imposter of Sally and a normal Bunnie Rabbot. The two are then inside the hospital, and Amy is enthusiastic by finding the others, but Tails sadly explains to them that they are dead. Amy, saddened by this, wonders what they should do. Tails, nervous but determined, tells Amy that they could use the effects of deja vu, and commit suicide to reset again. Tails says that the timeline will be reset regardless of what happens, and Amy agrees. Tails uses pills to put himself to sleep, but not before crying while doing so. Amy cries as well and does so, with the timeline resetting offscreen.

Tails finds Cream in Volcano Valley, and saves her from an enraged Tails Doll. The two then made it across Aqua lake and found Rotor. He gets by cutting his own hand, and heads to the hospital to find Sally and Bunnie. Cream however, is quick to notice Sally, as she had orange eyes. Sally rejects their offer and knocks away Bunnie, revealing herself to be Execun the whole time, however he is stopped by Tails Doll's rage and he attacks the duo offensively. By this point, his curse (from Exeller) as reached the full result, changing his fur color and eyes, and passes the curse onto Tails by scratching his eye. Tails however defeats him, and the two make it to the elevator. Unfortunately, they get stuck, and Cream blames herself for getting them stuck. Tails tells her it is not, and explains how he was back then before he met Sonic. However, he learnt from his mistakes and never gave up on himself. Tails suggests that maybe Amy was still out there, and agrees to survive with Cream. The two decide to head to sleep, but Tails remarks he has not eaten for two days... Not long after, he discovers the devoured remains of a helpless Cream, to which he devours down to insanity due to the curse taking full effect. He is reset offscreen not too long after.

In majority of other duo endings, Tails is a dead servant of Exeller, appearing to hunt down the remaining characters. One major role for him is the Sally and Cream ending, where he and Amy kill Bunnie and Sally, and hunt down Cream in the train while experiencing a power outage. They however fail to find her, as Cream activates the train and makes it, but is soon caught by Amy and Tails as they place down speed shoes boxes and spikes. Cream successfully evades them however.

In the Tails and Sally duo ending, the two head through the sewers to find the main tower. The duo are encountered by a now-corrupted Knuckles.exe and Dr. Robotnik.exe. Tails is battled on by Knuckles, and Sally battles Robotnik. After Tails defeats Knuckles, Knuckles tells him they will meet again, reminding Tails of the other timelines again, forcing him to kill Sally and then himself with her sword.

In the trio ending, him, Cream, and Sally all make it to the train where they meet Bunnie. Luckily, the train is able to be fixed thanks to Tails. Sally explains to them that she will have to leave them soon after. Unfortunately, Exeller and the now-corrupted Amy Rose, Knuckles, Robotnik, and Cheese all come after them on top of the train. The train crashes however, and Tails is killed by Knuckles.

If Amy and Cream, or none of the girls are killed at all, Tails, Knuckles and Robotnik leave Mountain Peak and head into Night Forest to go into Metropolis. One major example of this is the Crazy Amy Ending, where Tails and Eggman find Cream the Rabbit disheartened at a burnt Tails Doll. Cream the Rabbit tags along, and soon finds out from Tails that Amy's parents were murdered by Tails, leading to a determinant choice which impacts the endings. He decides to split up and group with Knuckles, but they are soon killed by an enraged Amy Rose, who turns them into servants to help kill the duo.

In the best ending of the game, the two groups finally meet up, and plan out the battle before heading to war. Tails remains in the security room to protect Cream, and watches the ongoing battle. He leaves Cream in the room to activate the backup generator. Tails manages to activate it, and saves the city for now, forcing Exeller to retreat. The group then reunite with Amy, but everyone except Cream are awakened by their inner demons by Ultimate Execun. Cream manages to save all of them are they make a circle around Exeller to head into the Illusion World, where they are separated, but regroup to battle Exeller one last time.

After the final battle, Tails is now knocked out with the others as a now free Exeller appears out of Sonic's body with his very own...

Personality Tails is a gentle-hearted, sweet-natured and loyal fox with a positive attitude. While he started out as timid and quiet, he has since opened up and become more outgoing over time. Tails is not one to grab the spotlight for himself and instead, is always ready and willing to help others without asking for anything in return. Him being young, he has a tendency to lose hope at times.
