What is the name of Sonic's two-tailed best friend?

Sonic’s two-tailed best friend is Tails, whose full name is Miles “Tails” Prower. He is a two-tailed fox and one of the central allies in the Sonic the Hedgehog series.

Tails was designed by Yasushi Yamaguchi as a sidekick character for Sonic. His nickname comes from his twin tails, which he can spin rapidly to lift himself into the air like a helicopter. The character’s full name is a pun on “miles per hour,” matching the series’ interest in speed.

Tails first appeared in the 1992 Genesis version of Sonic the Hedgehog 2, where a second player could control him. He also appeared in an earlier 8-bit version of the game, but the Genesis release made him widely known and playable. His flying ability gave the pair a useful contrast: Sonic supplied speed, while Tails could fly and reach elevated areas.

Shadow, Amy, and Knuckles are all important Sonic characters, but none is the classic two-tailed sidekick. Tails is typically portrayed as a gifted mechanic and inventor as well as Sonic’s loyal friend.
