okay, dd IS stronger, faster, and more durable than hulk, that is to be sure. Can hulk work himself up to dd's level? of coarse given enough time and rage he most definitely could. However, dd just isn't gonna give our Hulk-man the time he needs to do it. DD has a healing factor that probably works as fast (if not faster) than hulks does, and he doesn't even have any internal organs, so I don't think he can be rendered unconcious (that's just on opinion though). I don't think Supe's heat vision hurt doomsday, it just pushed him back in their first encounter, in hunter/prey he didn't even notice it at full blast, He even got hit with darksied's omega beams and it didn't even phase him. But Supe's heat vision can definitely hurt the hulk. DD's just as fast as the fastest hulk (that's not even worth argueing). Even IF hulk can go toe to toe with DD in power punches (which though I'm sure he could) DD's got more than just brute strength and speed, He's got the bone claws, (if they can cut superman, they're cutting into the hulk for sure). I don't think Hulk's gonna get diced to death with the claws or anything but, DD can shoot them out of his fists and use them like chains. But, the real danger they present is the poison they secrete. Hence, Hulk's gonna get woosey, slow down, healing factor won't work as fast, and he'll start making mistakes. Plus, it's gonna be hard for hulk to work up to that level of rage he needs if he's getting messed up by poison.
Someone said, when mindless, hulk wants to destory everything around him, that's no different than doomsday, doomsday's not usually satisfied with where he is until he's killed every last living thing on a planet (and then the planet itself in some occasions), it's his survival instinct. Doomsday killed Superman. On average, hulk can't even beat Superman, Doomsday beat down Darkseid in three or four hits, who is supposed to be on par with thanos (though I disagree, thanos owns darksied, imo), I've never seen hulk beat the avengers with one arm tied behind his back, like DD did to the JL, and has far as throwing DD into the sun,,,,,,,,bad,,,,,,,,i-,,,,,,dea. Doomsday gets his strength from the sun (like supes), if he gets thrown into it, I'm thinking that's only gonna give hulk big problems like oh i don't know a Nova-empowered-pissed off Doomsday of unfathomable potential (just a scenario).
.......Anyone who can put a whoopin on the entire green lantern corps (thousands) gets my vote easily ( i know he had a ring but still it works on willpower, and his willpower to destroy is incomparible).
Hulk's getting dropped like a bag o dirt.
