KratosvsThanos

This depends entirely on which Thanos we're talking about. Base Thanos — the Mad Titan without any Infinity Stones — is a different conversation from Thanos with even a few stones, let alone the full Gauntlet. Let's address both scenarios.

Base Thanos is immensely powerful: he's gone toe-to-toe with Thor, Hulk, and Silver Surfer simultaneously. His durability lets him tank planet-busting attacks, and his energy projection can threaten cosmic beings. He's also a tactical genius with technology that spans galaxies. But Kratos has killed Zeus, overpowered Titans, and matched Thor's Mjolnir. In a straight physical fight, base Thanos and Kratos would be competitive, with Kratos's rage and divine weapons giving him a real chance.

But Thanos with the Infinity Gauntlet is a completely different entity. With all six stones, he snapped away half of all life in the universe with a thought. He can manipulate time, space, reality, power, the mind, and the soul — each at a cosmic level. He turned Wolverine's adamantium bones to rubber. He imprisoned cosmic abstracts. This is a level of power that transcends anything Kratos has faced.

Kratos's best argument is that he's overcome seemingly omnipotent foes before — Zeus with the power of Fear, and he's resisted reality-warping through sheer willpower. But the Infinity Gauntlet operates at a scale beyond the Greek and Norse pantheons combined. Thanos with the Gauntlet could simply erase Kratos from existence.
