probably nimrod. i like nimrod. i cant think of anything hulk can do that would cause lasting damage to him. his weaponry is is enough to take on almost anyone, and if it isnt he can just adapt it so it is. this fight wont go much differently than the juggernaut nimrod fight, except the hulk might jump around and run and avoid losing as quickly.
This issn't the same as juggernaut vs nimrod, because who to say that a ultra-sonic frequency pitch works on the hulk, but than again the question is how fast can nimrod adapt.
The point is, that Nimrod would adapt and find a way to incapacitate the Hulk.
Hulk is not the kind of opponent that is going to be effective against Nimrod. Just hurting his physical form is not the way to beat him.
hulk will smash Nimrod into Lego
then fling the pieces wildly
some into orbit[upper stratosphere] other parts will land in china, to be turned into toasters. Latveria, where doom-bots will integrate the material into an ice cream dispenser and Wakanda where T'Challa will no doubt destroy the stuff. AIM will gather what remains to make a funky new talking gun for Deadpool.
Nimrod starts out stronger than Hulk. He reacts faster, AND can adapt.
If Nimrod shows up right after Hulk gets his cell phone bill, maybe there would be a problem.
But, from "go", Nimrod wins.
