Metal Sonic

Metal Sonic is the evil "robotic counterpart" of Sonic the Hedgehog, created by Dr. Ivo "Eggman" Robotnik. As well as resembling Sonic, he can also perform many of Sonic's moves, including his homing attack. Metal Sonic is always on the dark side throughout the series except Sonic Rivals 2, where he is one of the "heroic" playable characters.
