All of the Teen Titans, Two Green Lanterns, The Flash and Kid Flash, and The Question... vs The Joker and Harley Quinn.

It's probably touchy, but sometimes there's an appeal to 'invite-only events' where you do almost a mini RP inside the game and you can have a group of players who have already sort how they want it go and what they want accomplished.

I know that would also however rub people the wrong way who feel left out or that they should have been included.
