My take on Superman is he's the modern manifestation of the Hidden Prince archetype. Think King Arthur raised as a peasant. Think Moses,cast into the river and by purest chance raised by Pharaoh. Superman is the outsider who doesn't really belong, but who loves his adopted world so much that he'll fight to save it with all the powers he has.

I &hearts Superman. darthsatyr is annoyed by him (he's more of a Batman fan). So I don't think it's as much a gender thing as it is a mindset thing.

As for Wonder Woman, I think it's just as simple as a powerful woman in a world where women don't generally have a lot of power.
