Talk:Hulk VS Doomsday/@comment-3515785-20161023095039/@comment-27255656-20161023100618

It's actually quite simple, CanCan. When Doomsday is killed, he becomes immune to whatever had "killed" him the last time, except for if he is completely disintegrated or erased from existence. If Doomsday manages to absorb Hulk's gamma radiation, he would revert to Bruce Banner, a mere human, which would instantly guarantee Doomsday the victory. So Hulk can die if he is either completely disintegrated or his gamme radiation is absorbed and Bruce is killed, or being erased from existence, and Doomsday can die the same ways (Except for the gamma radiation thing because he has no radiation).
