Miles "Tails" Prower

Miles "Tails" Prower is a two-tailed fox and friend of Sonic the Hedgehog in the anime Sonic X. During most of the series, Tails' role mirrors his role in the games, though he sometimes plays a slightly smaller role than Chris Thorndyke. He quickly befriends fellow inventor Chuck Thorndyke, who helps him build the X-Tornado jetplane. Tails hails from an unnamed world in a parallel dimension to Earth.
