The angrier he gets, the stronger he gets—and Bruce Banner's gamma-irradiated alter ego has gotten angry enough to crack continents and punch through dimensions. The Hulk's strength has literally no known upper limit, he regenerates from virtually any wound, and his thunderclap can level city blocks. The only thing scarier than fighting the Hulk is the realization that he hasn't even started trying yet.

The Eighth Wonder of the World, a colossal great ape who stands as tall as a skyscraper and fights with the fury of nature itself. King Kong has gone toe-to-toe with Godzilla, swatted biplanes off the Empire State Building, and wielded a battle axe made from the dorsal plate of a titan. He's not just a giant monkey—he's the alpha of Skull Island, the last of his kind, and proof that sometimes the biggest underdog in the fight is literally the biggest thing in the room.
