I like Godzilla and I don't like Hulk but, Hulk takes the majority.
Hulk could tear Godzilla up.
The idiot can, after all, destroy a planet if enraged enough. That kind of raw power isn't something Godzilla should be able to handle.
I don't see Godzilla K.Oing Hulk although I think it is maybe possible for Godzilla to blast Hulk into submission but, I really couldn't gauge how much it would take, or if it's even enough to defeat Hulk.
Hulks' regen is sick and I doubt that one blast will put Hulk down. It would have to be a repeated assault . Problem is, Hulk isn't a big target compared to Godzilla, nor is Hulk going to stay still.
And even though I call Hulk an idiot, he acutally isn't anymore. Not for a while now. Hulk is quite clever. In fact, I want to say he has Banners intellect but I could be wrong. I don't read Hulk books but, I've read what others have said in debates.
My prediction: Hulk jumps at Godzilla, Godzilla fires. Hit's him. Dust clears, Hulk jumps out of the smoke, Godzilla blasts again, Hulk manages to evade, learning from his error. Hulk attempts to shimmy up to Godzilla's neck but Godzilla grabs him. Hulk breaks Godzilla's fingers. Climbs up and rips the big guys throat out.
On the matter of Superman...
Superman v Godzilla isn't even close. Superman wins, 10/10.
Superman v Hulk is just as rediculous.
Reason: Superman has a stronger base strength than either and can speedblitz them at faster than light speeds. Both get wtfk.o.'ed.
