Speed Man's Bio:

Speed Man, as his name suggests, was built for speed. He was built with wheels for feet. His design is specifically meant for robot rumble racing. Unfortunately, Speed Man was convinced by Virus Man that humans were disgusting creatures that needed to be eliminated. Speed Man willingly agreed to Virus Man's plans for a global robotic uprising against man-kind, but he didn't feel that way towards one human in particullar... And that human was his creator. Virus Man soon learned of this and dealt with the problem immediatly. By that time, Speed Man had realized that Virus Man's ideals were wrong. Speed Man was quick to warn his creator, but not quick enough. Virus Man had Speed Man captured along with Speed Man's creator. He forced the creator to watch in horror as all of Speed Man's memories of his creator were wiped clean from his data banks. All chances of Speed Man being one of the good guys went down the drain. To make it even more horrifying, Virus Man had Speed Man kill his own creator, slowly and painfully. All of Speed Man's feelings towards humans were wiped clean...

Speed Man's main weapon is the Speed Gun, where he launches a metal wheel out of his arm gun. Getting hit by one really hurts and can cause quite a bit of damage. Speed Man's weak against any slippery substances, due to the fact that they make him slip, slide, and crash.
