Miles Prower, better known by his nickname Tails and as he rather be called, is a young twin-tailed fox.
Ever since Tails was a baby fox, he's dreamed of being like Sonic trying to keep up our blue hero. Only spinning his two tails he can catch up with his speed, but sometimes, just to show off, Sonic explodes in a burst of super speed and leaves the fox behind.
Sonic has taken Tails under his wing and treats him like a younger brother, but
Tails wants to prove Sonic that he's someone to be counted on and don't want to be so dependant.
Tails have the ability to fly spinning his twin tails like a helicopter rotor and he
also learned his hero's Super Sonic Spin Attack.
He loves to building things and he's as talented as Dr. Eggman.
Sonic helped Tails build and he improved Sonic's plane,
the Tornado, and besides his talent with machanical devices, he has become an experienced pilot.
