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.

Wade Wilson, the Merc with a Mouth, possesses a healing factor so absurd he's been decapitated, incinerated, and atomized—and trash-talked his way back from all of it. He's one of the most skilled combatants in the Marvel Universe, proficient with every weapon ever forged, and is the only character fully aware he's fictional. His real superpower is being so annoying that even Death herself fell in love with him.
