Kratos. I've seen the fights tirek had and I'm not impressed.
The gods mere deaths caused the end of the world. If then dying could do that then they definitely could too. Helio's power could do it as stated by Athena in chains of Olympus.
Before I go into explaining Kratos'feats and why they are so OP. I suggest forgetting everything you heard from death battle and also stop judging his character from game mechanics. You'll never learn properly by going off those two things.
Anyways.
Kratos strength:
Atlas lifts all of creation on his shoulders. In real mythology it's supposed to only be the sky, but GOW changed this. Now he holds the earth AND the heavens. The heavens, much like the underworld, is infinite in size. Atlas is strong enough to hold all of this. Kratos was strong enough to stoo atlas from crushing him. And since Kratos was the one to chain him there in the first place, we all know he was not holding back.
Speed:
Kratos kept up with Hermes then took his speed for himself. You can blame game mechanics for thinking Hermes isn't that fast. He definitely is. He delivers souls to the underworld and dreams to mortals simultaneously. The underworld, like I said before, is infinite in size. This almost makes his speed infinite. Almost. Did you know that Hermes boots also grants the user the ability to fly? Only reason Kratos doesn't use them to fly is because it would be weird if the players just flew around everywhere.
Durability/endurance:
Kratos tanked a direct lightning blast from Zeus. Kratos didn't even receive a scratch, all that he got was launched back. Gaia however, the primordial titan/Goddess of the earth. Got her arm fucked up and launched off the mountain. Gaia is capable of splitting the continents with her breathing and with a sigh in her massively weakened spirit form she shook the infinite realms. Kratos also prevented his soul from being taken by Hades. Atlas however, failed to do this. But Hades had help from Poseidon. Kratos also tanked shots from Poseidon. Kratos also took the power of the sun head on. People assume It was just a blinding light that Helios was doing. But having a blinding light shine bright upon you isn't supposed to kill you. Especially if your Kratos. Yet you lose health and die if you fail to block it or reach Helios on time.
Now onto the reason Kratos is a universal to multiversal character.
Kratos defeated 3 primordials, reason why this is a astonishing feat? The primordials were the ones responsible for the creation of the universe. The ones Kratos defeated was Thanatos, Uranus and Gaia.
There's a version where Uranus himself created the universe.
Thanatos, the living embodiment of death. Lost easily once Kratos stopped holding back and went berserk.
But how did they create the universe? Their fighting did.
The primordials clash created the universe. (Causing the big bang) Simply punching each other formed and shaped the galaxies.
Kratos defeated Uranus and Thanatos in their strongest beast forms.
Kratos also overpowered Baldur in strength.
Baldur 3 shot the world serpent. The world serpents clash with Thor splintered the world tree and that got him sent back into time. Each strand of the world tree is a universe. Realms in gow is basically a universe. So that means that the world serpent and Thors fighting could be felt across 9 universes.
Kratos is stronger then all 3 of them.
Conclusion.
Tirek is getting mega stomped. There's nothing he can do to stop Kratos. There's nothing anyone can do to stop Kratos. Telekinesis will be easy for Kratos to break out of, magic is useless as well. Anything they can do will be useless, especially with POH.
