Ignoring the Flood's obvious favoritism towards Hulk, who would win in a deathmatch?
-
No winner. The fight would go on forever. Hulk can't die, and keeps getting madder, with no top end. Doomsday fights until he dies, and then resurrects evolved to deal with what kills him. Both have no end to their power-set. I guess Doomsday might win, as he is immortal, and Hulk would eventually die of old age. But as a result of the fight? Neither.
