unless doom can pull something from out of his ass and steal sbp's powers from the onset, dc wins this. ww with all her gadgets and trinkets should be sufficient for ww hulk, at the very least keeping him busy. sbp takes out doom....that leaves thor and he is a god...lasso of truth ftw....dont know if the power gem negates that but as mentioned sbp might be able to wrest it from him, or at least take away the hammer.
I don´t know about Superboy speedblitzing him, I mean when he fight Kon-El (both rounds) it looked like a pretty slow fight.
Seeing how that happen, and that Thor could tear stars in two, I mgiht just give it to him (Over Supwerboy)
World War Hulk is pretty good as well, clearly underestimated as he have taken down Black Bolt and Dr Strange, with just physical strength.
But I have no idea what Doom is doing there without prep time.
6/10 in DC favor.
