That's a stupid way to debate.
Why would Hulk have a hard time killing Kratos again?
Kratos only needs to decapitate Hulk? What's stopping Hulk from doing the same? What's stopping Hulk from unleashing a burst of gamma radiation that destroyed an entire planet when fighting Red She-Hulk?
Don't rely on no-limits fallacies in favor of Kratos.
You're going to need to provide context and feats for character A if you want to get into debating.
Hercules may have the same fighting style as the Hulk, but he possesses no feats comparable to those displayed by The Hulk. You can't just assume that just because they're similar, that they can do similar things. You're going to have to look at quantifiable feats like strength, durability, speed, etc.
In terms of strength, nothing in God of War has even shown planet-busting abilities so that's already a big disadvantage on their side. If one says Hercules from God of War could do it, it can be easily rebuked by saying, show when and where in his series he actually showed that capability.
In terms of durability, no one in God of War has directly tanked being struck by a blast that actually destroyed said planet. Hulk has an actual, quantifiable feat. Kratos does not. Hercules does not. Ergo, based on evidence, durability isn't even a context. Hulk's durability surpasses Kratos' offensive abilities, thus, attempt at decapitation won't work.
Kratos is used to fighting things stronger than him? Yeah, in the context of his universe maybe. I'm willing to bet a majority of the characters in God of War can't even do anything to one of Hulk's most consistent opponents like Thor.
It shouldn't be a 70/30 favour for Hulk. That implies there is slightly less than 1/3 chance of Kratos actually beating Hulk when based on feats, it would actually be near 95/5 in favor of Hulk.
Possessing a lot of items means little if a majority of them won't be able to do much to the Hulk in the first place. You're going to have to provide quantifiable feats for any of your claims if you want that part to be taken not at face value.
No resistance to magic you say? Hulk broke out of Grey Gargoyle trying to turn him to stone or Enchantress trying to turn him to glass. Medusa's gaze isn't even true transmutation considering in the novels, it only encased one in stone and could be easily broken out of. That is supported in the games when regular people and Kratos can break out of being 'turned to stone' after a time.
He resisted Dr. Strange's magical attacks without too much difficulty during World War Hulk so don't go make the claim that God of War magic is better than the ones displayed by the Sorcerer Supreme. He ripped apart mystical barriers using his hand alone, he can see Astral non-physical forms and actually interact with them, and he has actually broken the Crimson Bands of Cyttorak, something which shouldn't be physically possible to do so which means Hulk has some effect over magical things to an unknown extent. He isn't Superman, magic isn't going to be oneshotting him in the first place.
You can try to claim that Kratos can try taking Hulk's soul. Except for the fact that Kratos could resist Hades doing the same to him. Nothing's stopping Hulk from resisting the same way. Hell, nothing's stopping Hulk from letting Kratos take Banner's soul instead. Bannerless Hulk would just proceed to kill everything. Even when Hulk's soul was siphoned into the Destroyer armor, Hulk just kept smashing.
There is nothing in Kratos' arsenal that can change the outcome nor have anything comparable to the opponents Hulk faces. This is not a 70/30 matchup as you're trying to insist.
You ain't reading what I wrote.
Atlas lost his soul to Hades, after being weakened by Poseidon. It still took him time to do so. Kratos resisted Hades doing the same to him so what's stopping Hulk from resisting as well? I already pointed out that even with his soul in a separate place, Hulk continued to fight. I pointed out that even when someone tried to take his soul, Banner's soul got taken instead and just left a rage-filled Hulk that's even more powerful than Hulk with Banner.
You are making a stupid assumption that the Blade of Olympus can even decapitate The Hulk despite you providing no feats of it doing enough destructive capacity that rivals what The Hulk has tanked. You're assuming that The Hulk won't react fast enough to the Blade of Olympus despite the fact that Hulk consistently reacts to hypersonic opponents and has regeneration that won't be stopped by simple decapitation. Do explain how a featless Head of Helios has a bright enough intensity that rivals a nova blast from the Human Torch or the blast from The Sentry. You want to use bullshit like that, then I'll just use the description for Sentry having enough power to rival a thousand exploding suns. Something that Helios obviously doesn't have.
The golden fleece is not an omnidirectional form of defense and nothing's stopping Hulk from ripping it away from Kratos. You're assuming a no-limits fallacy as usual.
Again, you've provided no proof and just continued to spout off idiotic assumptions about what Kratos 'could do' and taking no look at what Hulk has actually shown. You didn't even look at the parameters.
Strength: No contest. Hulk has provided better feats in terms of pure physical strength.
Durability: The golden fleece has no feats of durability that compare to Hulk tanking a planetary explosion so don't fucking assume that it can tank a planet-destroying blast or just being ripped off from Kratos' shoulder.
Destructive Capacity: Hulk has destroyed a planet, has destroyed an asteroid twice the size of Earth, and held together tectonic plates to stop a planet from destroying itself. Kratos's best feat is barely standing up to the two fingers of a titan who is holding up an incomplete crust of a flat world from God of War. Nothing close to what Hulk has done.
Speed: Hulk has reacted to hypersonic opponents like Quicksilver and Thor. Kratos's fastest enemy, Hermes, doesn't even approach subsonic level. No feats, no proof, nothing you've said even shows characters in God of War moving at sound speed.
So, no. You're still doing the usual bullshit of assumptions when you say Hulk would have serious difficulty with Kratos despite the fact that nothing Kratos has done are on par with Hulk's enemies.
