THis is been done I think. Tho I think Doomsday cremes Hulk. Doomsday has been beaten by massive strength before and that is pretty much the hulks gimmick. He aint' out punching Superman so I know he ain't out punching Doomsday. Doomsday has tougher skin, poison tipped bone claws that can cut kryptonians. He also has super speed. Fast enough to make superman go whoa. So Um DD takes it.
yeah you also forget they take time and umm DD's abilities are vertially unlimited if you put into thought that he just evolves after every loss, he wasnt strong enough to even hurt superman when he gave him the first punch he then evolved FAST and put superman through a window with his second punch, he can excrete venom that kills even superman and his spikes even hurt superman, he is also fast enough to fight superman one on one, hulk isnt some super uber guy who snaps his fingers and suddenly is unstoppable neither is DD but DD's abilities grow alot faster then hulk's is all im saying.
