This one is fun! The idea is that some group of extra-dimensional omnipotent beings has pulled characters from across all the various publishing universes to compete in team-on-team tug of war contests. Here are the teams (Marvel and DC get multiple teams because, come on, Marvel and DC):
I don't want to prejudice the vote, but you have to think the only thing Batman is contributing to DC Team One is some Bat Lubricant for the rope, because he's got no business hanging out with those heavy hitters. As for their Team Two, the biggest question is who disintegrates whom before the starting gun sounds for the first match.
Anyway, have fun, and by all means let 'er rip in the comments about which group you think has the edge, and which is going to get turned into paste by the opposition.
