میلایس پرووایر

The name "Miles Prower" is a pun on "miles per hour," a reference to the famed speed of the Sonic the Hedgehog series. He is a young, male, golden-yellow, anthropomorphic fox with two tails (similar to the mythological kitsune, or "yoko," which was often depicted with up to nine), hence the nickname. He is able to use his two tails to propel himself into the air like a helicopter for a limited time. His debut was in October 16, 1992, taking part in the 8-bit version of Sonic the Hedgehog 2; the 16-bit version was released that November.

Viewing Sonic as somewhat of an older brother, Tails looks up to the hedgehog and aspires to be like him. Though lacking confidence in his abilities as well as experience, Tails does things in a more logical sense than Sonic, often using his ability with machines to turn the tides.
