Round One:
It's been five years since Al Gore won/lost the presidency of the United States. During that time he's loosened up quite a bit, doing guest spots on Futurama and Saturday Night Live and generally making a good living through laughing at himself. But deep beneath that now jovial exterior lurks the same cold, robotic interior as always. Despite convincing the public otherwise, the Gorebot still lurks beneath the surface, growing even stronger as Al represses his natural urges to kill all humans. One day he finally snaps, going on a classic robot rampage. Humanity turns to their one hope: another psychotic robot. Iron Man has recently returned from killing all the humans in Utah (leaving only Mormons behind), and he doesn't take kindly to another metal man muscling in on his territory. Iron Man confronts Al Gore, and the battle is on.

Unfortunately for Iron Man, he has been getting a little overconfident lately, having taken out mostly soft-fleshed humans up to this point. When he sees Gore's fleshy exterior, he figures that this will be another easy fight and doesn't come on with the same fury that he used to have. Gore, on the other hand, is like a binge eater coming off a diet and throws himself happily into the fray, pummeling Iron Man mercilessly. Finally, he throws his foe off a bridge, leaving Iron Man to rust in a river as Gore continues his murderous rampage. Round One goes to Al Gore.

Round Two:
Iron Man's boots of lead don't do much for swimming, and he sinks immediately to the murky depths at the bottom of the river. There he lies for decades, maybe even centuries. Eventually the river dries up and archaeologists dig him out, chipping off the rust and polishing him up. He thanks them by murdering them all violently and stalking off into the wastelands of America. It turns out that Al Gore actually rules over this post-apocalyptic United States, since no one was there to stop him from taking over. Iron Man eventually finds Al in the crumbled old White House engaging in his favorite game, which is of course parading around the oval office and kicking George W. Bush's skeleton in the groin while yelling, "I won the popular vote!" Personally, I find this idea to be so fun that I don't blame Gore one bit for not noticing the killer robot walking up behind him. Iron Man proceeds to rip Al Gore's face off, revealing the metal skeleton underneath. Round Two goes to Iron Man.
