Champion of the universe (marvel) vs Karate kid (DC)

The best of the best go at it. Who takes it

Not sure if KK can put him down long enough to qualify as a win in a forum fight (some others need to weigh in on that), but he embaresses the hell out of Champion all day long.

Incredible. I read karate kid died. My only question is how? I mean they even have him taking down superman

He did die. Twice.
