Omigod. I now have this whole saga in my head, where the DC and Marvel universes collide and of course everyone fights, then teams up to stop Lex Luthor. Except that Jim Hammond and Roy Harper hook up partway through the first act, which pisses Namor off royally, so he defects to Luthor's side. In the end, Jim brings him 'round with the amazing healing power of android love, and Namor betrays Lex at the climax and returns to the Light Side of the Force. Then he and Jim reconcile with a big smooch (hell, throw Roy in there too, don't want him to feel left out).

Diana and Power Girl is so awesome I'm amazed this isn't canon yet. Whoa.

Red Skull/Iron Man scares the hell out of me. Even scarier than Fixer/Iron Man someone suggested once. Tony's probably not Aryan enough for Schmidt, though.

Hilda Zemo just gets a turn with everyone on the list in reverse-alphabetical order.
