The name "Miles Prower" is a pun on "miles per hour", a reference to the famed speed of Sonic the Hedgehog. He is an eight-year-old fox with two tails, hence the nickname. He is known to be Sonic's sidekick and best friend as well as a mechanical genius. He is able to use his two tails to propel himself into the air like a helicopter for a limited time. He debuted on October 16, 1992, with the release of the 8-bit version of Sonic the Hedgehog 2; the 16-bit version was released that November.
Tails is best known for having two tails and being Sonic's sidekick. He is one of my favorite video game characters.
