Heh, Thor bfing Hulk is something he should do every time..
Really, no matter how strong Hulk gets, the fact he can't fly should be a huge detriment. When Young Justice fought Despero, they took advantage of the fact he can't fly by having Impulse grab and toss him up into the air, and Superboy hit him back down into the Earth.. Guy Gardner launched him with the old anvil on a seesaw routine.
And I think Supergirl actually did the smart thing and brought one Doomsday into orbit, from the recent Doomsday centric storyline.
ANY fast flying brick should have a major advantage over a non flier who can't fly, simply by launching them into the air, where the flier can keep attacking them, while the non flier is basically stuck in free fall..
Like a Tekken infinite juggle combo.
Thor could certainly do it, since he can fly, and quickly. He did it a little bit in Fear Itself, even, with his mid air combo.
