I'm just calling them avengers because it's a marvel line up but otherwise it's just a team vs the Justice League.
Nova Prime(w/ Worldmind)
Superman(15 minute Sun-Dip)
The Flash(Wally West)
Green Lantern(Hal Jordan)
Location: Deserted indestructible planet
Everyone is fighting to the best of their abilities
Pre-52 feats for the Justice League
Captain Atom can't become so powerful as to create universes and crap
Who takes it?
