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.

King of the Olympian gods and supreme ruler of the heavens, Zeus wields thunderbolts forged by the Cyclopes that can vaporize mountains and shatter the sky itself. He overthrew the Titans to claim dominion over the cosmos, and his authority is absolute among gods and mortals alike. His only known weakness is an inability to resist a dramatic entrance—and mortal women.
