Before any superman fanboys call me a troll, I would like to make it clear that I am serious about this thread. Here are the circumstances:
Joker has stloen batmans kryptonite and his constingency plans.
He has scarecrows assistance and fear toxin.
Fight takes place in a caulostrophobic arkham asylum area.
Joker can incorporate knite into his laughing gas and has the asylum in his control.
Joker also has acess to the titan formula.
How he will use them will depend on how the fight goes.
Who would win?
