Each team gets 1 day to prepare, and can consult with any characters from their respective universes to strategize. Anything that can be accomplished in a day is allowed. The characters only know that they will be facing their toughest fight yet. Enchantments, armor, gadgets, etc are all allowed, with the exception of major game changing artifacts (Reality warping, time control, matter manipulators, etc)

Only Moral rule is that there will be no intentional killing. Though some death may be inadvertent.

I realize that many of these characters at one time or another have been damn near invincible, so try to go by an "average" for each character.
EDIT: I just wanna say thanks guys, for the polite and intelligent discussions on this thread. It's my first post, and the respect throughout has been quite impressive. Not many sites can have a thread go more than a page without bitter arguments and disrespect amongst these type of discussions.
