Well lol. KM's dog is slowly inching toward a win in this thread through sheer attrition.
I still say I take it, though. Among names that would actually decide the fight, you've got Thor, Superman, and the 11th Doctor. I've got WS Doctor, 10th Doctor, and Thor. You'd have the best chance in a non-prep scenario (still very little chance whatsoever with prep, even with Batman, who would become relevant at that point). But I'm not sure you have an answer for Jeroen yet. A Superman speedblitz would do it, and at that point I'm boned. But if you don't pull it off, I win handily.
If I can find pics of me as Alan Scott, I could one-up you yet again. But it's damn close at this point.
