Dr. Wily used Ra Moon to create Top Man, with Ra Moon copying data from Dr. Wily's laptop to bring Top Man into being. He was also a part of Wily's Robot Master army, also commanded by Doctor Eggman, in the Worlds Collide crossover event. During a massive battle, he was seen racing Shadow the Hedgehog, only to be knocked out when Sonic the Hedgehog sent Hard Man flying at him to the other hedgehog's chagrin. With the effects of the doctors' Genesis Wave reversed, Top Man was returned to his universe unaware of these events.
