Marvel/Attack on Titan Crossover

Personally I think Doom would destroy all of them so it seems a bit pointless.

but why would Doom destroy all of them?

He's taken over the world twice, and given it up because he was bored, all Spawn style and shit, so he can do pretty much anything he wants to at this point. He doesn't need them to help him or anything so the next best answer is just kill them off isn't it?
