Atheist superheroes?

[Esquilax]

Now there's a strange concept... atheists fighting the very things which they do not believe exist in the first place...
Bzzzttt..... Does not..... comp... pute.... baaaarrrrrrghghgh

From what I've read, it seems as though the creatures themselves do exist, but instead of literally being angels and demons and whatnot, they're extradimensional beings capitalizing on the mistaken assumptions of the faithful in order to accomplish their goals.

It's a kind of cosmic con-job they're fighting, rather than something as nonsensical as it initially sounds.
