So Batman and Superman are supposed to be against each other? In that case I don't want to play, because that is stupid. Sigh. Unless this isn't the case...?
Superman actually has two other main weaknesses asides from kryptonite. He is solar powered, without the sun, he doesn't get his powers. Magic, also a main weakness.
Also, if he is hit with enough force it can actually hurt him. Darkseid.
That's actually.......an excellent idea. I had wanted DS to have a contract for somebody, but I hadn't decided yet. But what if he has a contract for both Bats and Mr. J, because otherwise we would need a more compelling reason for Batman to ultimately work together.
Maybe Joker has information Batman needs, so in return, he is unable to afford loosing the Clown Prince until the input is put out?
