Miles Prower better known by his nickname Tails is a two-tailed fox who is Sonic's best friend and sidekick. His name is a pun on "miles per hour". He is able to use his two tails to propel himself into the air like a helicopter for a limited time. Yasushi Yamaguchi, originally the main artist and zone designer for Sega's Sonic Team, designed Tails for an internal competition for a sidekick to Sonic. His first appearance was in Sonic 2 for the Game Gear, where he was kidnapped by Robotnik for a "hefty" ransom, and was first made playable in the Genesis version of Sonic the Hedgehog 2. Tails has appeared in almost every Sonic game since his first appearance.
Tails has also starred in games without Sonic. His first solo game was Tails' Skypatrol, a puzzle-like game for the Sega Game Gear released exclusively in Japan. This was followed by Tails Adventures later the same year, a platformer with role-playing game elements. Frequently portrayed as a sweet-natured and humble fox, Tails used to be picked on because of his twin tails, before he met Sonic. Tails has a very high IQ and has great mechanical ability.
