Note that the term animated universe here is somewhat of a misnomer, as unlike their DC counterpart, Marvel has no shared animated universe.
Like the DCAU, it's not as strong as it's comic counterpart, but powerful in it's own right. Characters featured include Galactus, Surtur, Eternity and even the Beyonder.
