Miles Prower, better known by his nickname Tails (Japanese: テイルス), is a character in the Sonic the Hedgehog series of video games, comics, and TV shows released by Sega. "Miles Prower" is a pun on "miles per hour", a reference to the famed speed of the Sonic games. He is a young fox with two tails, which enable him to fly. He is believed by some to be a kitsune. He first appeared in 1992

The character's actual name is "Tails Prower," but if you mean that your GW character will be "Tails Power" instead of Prower, by all means go ahead.
