dude if iron man can put up a fuss against fin fang foom and the hulk can rip him apart. Godzilla would smear his ass into the ground.
godzilla has more powerful fire breath, is physically stronger, and has a healing factor that can regenrate him entirely from a peice of skin, bone, or organ.
It took the avengers, the FF, the champions, sheild and spiderman to even slow down marvel's weak ass godzilla, and the only reason he stopped stompin on new york is because his "buddy" asked him to.
I have no idea where people get the idea that godzilla's this big stupid lizard that's too slow to catch a slug. Godzilla can dodge giant flying bolders, he can box better than rocky in that he can both block and dodge punches, he can dodge giant monsters flying at his face (gmk), he swepted mechagodzilla to fall towards him and turned around and blasted him before he even hit the ground.
And comic book godzilla, don't even get me started. He easily dodged a peice of street that herc threw at him and into orbit. and he has kung fu fights with giant samurais.........and charles barkley. lol.
