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.

Genius billionaire Tony Stark built the first Iron Man suit in a cave with a box of scraps, then spent decades upgrading it to go toe-to-toe with gods. The latest suit features repulsor beams, a uni-beam, nano-regeneration, and enough firepower to give small countries anxiety. Proof that with enough money, intelligence, and engineering, a man in a tin can can outclass most of the Marvel roster.
