5 people to save the world.

I would be interested how a DM would handle Dr. Manhattan, since he was at one point human.

Moot point since he experiences time differently, so unless your team knows his weakness to tachyons and has the ability to create them they couldn't possibly get the jump on him

Anyways, its not fair to just pull out the Star Wars rulebook to arbiter these disputes, why wouldn't the Marvel Comics characters use the old Marvel Superheroes RPG rules? I mean if I want to win I can just open up the overpowered RPG bible (Rifts) and pick some multidimensional entity like Splyncryth or something.
