Cobra Commander vs. The Joker
The two have been locked in a grimy, old weapons factory. Both are unarmed, and the factory is only dimly lit. However, there are plenty of make shift weapons about, and maybe a few rusty old real ones. In addition it has been used as a chemical storage facility for some time... with many barrels of dangerous liquids scattered liberally around the huge structure....
So, which of these two would be able to out wit, and out fight the other first? Which would be the most creative and successful in the way they use the environment?
