CatGirl
Action, adventure and romance
I can understand that if you're writing with people you can't trust, but then you'd have to wonder why you're writing with them at all? Or maybe I've just been extremely fortunate. We've had Superman, Green Lantern, Flash, Shazam and Wonder Woman (all of whom can go super OP if they wanted to), but they've all been very respectable. Each plot is planned way ahead, and the result of each fight already pre-planned via OOC communication before they enter. That way, it's not possible to aggravate anyone in the story.
