The Best Fighter

Karate Kid no doubt. His chi is just too insane - imagine what he would be like with supes strength.

One of the reasons I thought about this thread is like, picture beings like Eternity getting the crap kicked out of them cause they actually have to DO something, lol.

wouldn't this get rid of healing factors or strength they previously had or not. I would say KK easily.

Yeah, all previous powers are erased in the process, including strength levels and healing factors.

Black Canary is very good go check out her respect thread

Cap, for sure. That is, if they can JUST use strength.

They can only use strength and intelligence, basically. There is no prep time and nobody can actually bring along weapons, but they can use their environment. Example, Batman can't use his utility belt, but if he wanted to, he could pick up a car and throw it at someone.
