Miles "Tails" Prower, referred to as simply Tails, is Sonic the Hedgehog's best friend and a main protagonist from the Time Eater Arc onward. Tails was captured by Wario sometime before he captured Zelda. Tails is later freed by Sonic and Classic Sonic and from that point onward, Tails teams up with his younger self to defeat Time Eater and restore the timeline. In Fight to the Finish, Tails is killed in cold blood by Samus Aran. Tails is later revived by Black-Star Shenron as Samus is defeated. In Season 22, however, Tails secretly betrays his friends due to a seed planted in him by Yami Bakura. Later, Tails is, in a tragic turn of events, killed by Meta Knight. Tails is later revived in order to stop Samus.
Classic TailsEditClassic Tails is Tails' younger self. He first appears during the Time Eater Arc, where he finds Classic Sonic and his future self. Classic Tails is later turned into a trophy by Wario, but is freed by Sonic and Classic Sonic. Classic Tails then teams up with his older self to combat Time Eater and restore the timeline to normal.
- Tails is the only character whose past self appeared before him in the Time Eater Arc.
- Tails becoming an antagonist in Season 22 is a reference to the time he was mind-controlled in Sonic Colors, though instead of a mind control device, he is brainwashed by a seed created by Yami Bakura.
