What happened to the original question? I has access to an exhaustive mythos of two thousand years based on another two millennia, at least. A battle between good and evil is intrinsic to it. The difference is it's a conflict for the souls of humanity, not between super hero gods.
As for super heroes, it's just a modern fiction on archetypal ideas humanity seems to come back to. It doesn't have anything to do with Laird's beliefs, I just like Kirby is all.
