Who is the strongest character Bruce Wayne can beat?

This is Pre-52 Bruce Wayne. No Batman suit, gadgets or stealth. Who is the strongest person he could beat in a cage match?

This question is really open ended. You should probably ask who is the toughest street leveler Bruce could beat in a cage match.

batman can beat most people with prep and has given wonder woman a hard time on multiple times without prep and has beaten grundy maul and even a guy who copied manhunter powers without prep granted the last one he was attacked in his cave.

He caused an explosion, something he can't do in a cage

@dondave:

true I forgot the cage part.

@dondave: oh damn I had no idea this was done I searched. Unintentional.

Chuck Norris. Yes I went there...
