15 Most Insanely Overpowered Superheroes In The Marvel Universe
10. Thor
As already established, you don't get much more powerful than actual Gods - even when they're bound with humans to teach them a lesson as the God Of Thunder was by his disgruntled father.
Thor is unstoppable, can stand toe-to-toe with the Hulk and is worthy enough to wield Mjolnir, one of the most powerful artefacts in the Marvel universe. He has strength greater than all of Asgard's Gods - including his father - and once lifted the Midgard serpent, which was said to weigh half of the Earth, and his mysterious Godforce is strong enough to kill immortals.
He might not be as powerful overall as Odin, but he is similarly able to call on quirks (like his Godforce and his ability to channel Thorforce - basically his version of Odinforce) that make his powers unreasonable and undefeatable.
And impressively, whenever he is shown to command insane levels of power, or commit impossible acts, he barely seems to lose any of himself. It's like he doesn't even have to try.
