Miles "Tails" Prower is an 11 year old fox, born on the day of Dr. Ivo Robotnik's takeover of Mobotropolis. His father was a general in the Kingdom of Acorn, and upon discovering Robotnik's planned takeover, was roboticized. Since he was young, Tails has been at Sonic's side, helping him and the Knothole Freedom Fighters defeat Dr. Eggman and other evil forces. Unbeknownst to Tails for many years, he was also destined to become the "Chosen One" by the Ancient Walkers to fulfil a prophecy. With guidance from Athair, Tails eventually fulfilled the prophecy and stopped Mammoth Mogul from destroying the multi-verse. He continues to be at Sonic's side in stopping the forces of evil.
