1. doom
2, 3, could be stalemates but i'm leaning toward doom anyway. not sure how apoc would get through doom's forcefields. not sure what apoc would do vs the crimson bands either. or what if doom tried possessing him:
he's also got some pretty impressive blasting power, as well as neural disruptors that have one-shot ko'd colossus with just a touch.
it's hard for me to see apoc getting through those forcefields. easier to see doom being able to win this, imo.
