A hero who trained so hard he went bald and accidentally shattered the concept of power scaling itself. Saitama can defeat any opponent with a single serious punch—that's not an exaggeration, it's the entire premise. He's punched through dimensions, sneezed away Jupiter's atmosphere, and his biggest daily challenge is finding a sale at the supermarket before it closes. The ultimate parody character who is, paradoxically, completely unbeatable.

The Mad Titan of Marvel's cosmic hierarchy, Thanos is obsessed with universal balance and willing to snap half of existence out of reality to achieve it. Even without the Infinity Gauntlet, he can trade blows with the Hulk and outthink Reed Richards. With it, he is essentially God—capital G—with a chin that could cut diamonds.
