Superman et al, DC Marvel

Hello there, super-hero fans. I figured the best way to get a lot of attention is to grab on to someone like the big guy here. I have an interesting multi-parted question to put out there, so spread the word out there so there can be some good results. It kind of goes hand-in-hand with the DC vs. Marvel collaboration a while back. My question is this: In one huge battle royal, everyone for themselves. including ALL of the heroes and villians that you can think of, which two individuals would the final battle come down to; who would be determined THE last one ALIVE ;and by what means,all can be used, did this lucky SOB win (setting aside all godly attributes, good and evil, to make it fair to the mere mortals)? Can't wait for answers!!

It probably would be the Hulk, superman is much faster and both strengths are huge, but the hulk would go up against anything. For the side of the supervillians, perhaps juggernaut, Fin Fang Foom anyone?

This is from the guy who asked the question; it doesn't have to come down to hero vs. villian. Just #1 duking it out with #2, no matter who you think they are. Just thought I'd clarify that.

Captain Universe with the added power of the enigma force!

My vote goes to ....

THE SPECTRE vs THE WATCHER

Anyone who sees this- WHO WINS? Everyone is just putting the final match-up and aren't jumping at the chance to write the ending of all time by including HOW the character wins. Remember: it can also be hero vs. hero, villian vs. villian, DC vs DC, Marvel vs Marvel, etc., etc....
