Tails

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[3] fox with two tails,[1] hence the nickname. He is known to be Sonic's sidekick, best friend,[1] and a mechanic.[1] He is able to use his two tails to propel himself into the air like a helicopter for a limited time.[1] His debut was in October 16, 1992 in the 8-bit version of Sonic the Hedgehog 2; the 16-bit version was released that November.
