If the two were to fight, Mickey Mouse would probably win. The reason being Mickey has a better left hook and Robocop not only has a glass jaw, but is susceptible to taking a dive due to his colossal gambling debt to bookies.
If Robocop were allowed to use his guns, Robocop would still lose due to disqualification because in his exuberance he'd accidentally shoot the ref in the face, which is frowned upon.
So either way, Mickey wins. He's one bad mother shut yo mouth but I'm talkin bout Shaft and I can dig it.
