The super-soldier serum turned scrawny Steve Rogers into the peak of human physical perfection, and his vibranium shield can absorb a direct hit from Thor's hammer without a scratch. Cap is the best hand-to-hand combatant in the Avengers, a master tactician who once outmaneuvered Thanos, and possesses a moral compass so unshakeable he wielded Mjolnir. He doesn't win because he's the strongest—he wins because he does not quit.

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.
