I'm favoring Apoc, but only if he finds a way to neutralize DD. Apoc could always toss DD into Lunar Orbit and win with BFR. But if he has to fight him, he's in trouble. Doom could beat DD with prep, but not in a straight fight. Apocalypse might be able to actually do Alpha said and reverse engineer a way to put DD down permanently. I'm just not sure he can do it on the fly. And if Apoc can't do it, Doom's sure as hell not going to. Apoc is THE expert on mutagenetics. If Apoc or Doom stop DD, then Apoc takes it. But if nobody can figure out a way to stop DD, then he takes both out. But I should point out, that given the usual rules in fights on KMC, Apoc could mindrape DD, and thus kill him. Since DD's resurrection counts as coming back from death, by the rules, Apoc would win. But if you're allowing the ressurection, then they may not be able to stop him.
