Richard B. Riddick vs The Joker (Ledger)
Didn't see a Riddick matchup, so here we are.
Battle takes place on Mars City from Total Recall, as to not to give either person the advantage.
Joker's insanity is matched by Riddick's brutality. Each can improvise on how to kill their opponents (Riddick with a teacup and Joker with the pencil).
Both men are armed with the following: a pistol, a submachine gun and their respective knives.
Who wins?
