Since in an earlier thread it was decided that Batman could take out a T-Rex, I thought it's only fair to move it up a notch and see if he can take out...
Batman (pre-52) vs King Kong (last movie)
Random encounter, in character, win by death or KO. Battle in a field surrounded by trees and large rocks (similar to Kong image). There is enough fallen wood around to make a spear if needed.
Batman has all his standard equipment.
