Who will win the next Deathbattle?
Darth Vader (Star Wars)
Doctor Doom (Marvel Comics)
Don't underestimate Doom. He's got more than a decade more experience than Vader, plus got extensive experience against cosmic level opponents AND he has an army of robot decoys with which to distract Vader until he is ready to strike. Plus, Vader is basically a lackey to Palpatine while Doom is very much the one in charge.
