I'll call it now: they fight to a draw, before uniting against their common foe. Cue the horn section.I wouldn't mind worshipping Superman, but I have a feeling that Batman is going to whup his ass next year and undermine the basis of my faith.
Ya, that's fine but realistically, why would Superman ever need to unite with Batman?
That's like Mike Tyson saying "Well, it looks like these guys are in serious need of a beating. Come on, Pee Wee Herman, let's pound some manners into them". Pee Wee Herman may be a fine gentleman but he really can't add much to Mike Tyson's effectiveness in a fight.
It's like when the Avengers bring Hawkeye along. When you have the Hulk and Thor in a fight, it's a moot point as to whether Hawkeye bothers to join in. Batman is irrelevant in a fight that has Superman there.
