Maxwell Lord vs. the Purple Man
No prep. They are not to attack or attempt to mind-control each other in any way. Their job is to attempt to mindcontrol a subject in the middle of the room. The subject has absolutely no free will whatsoever. The subject just so happens to be a Class 100 powerhouse. In order to survive, they must attempt to mindcontrol the subject into killing their foe.
The subject is 100 feet apart equally from each opponent.
They can only begin at the sound of the bell.
