Deadpool is a Marvel antihero and mercenary known for his red-and-black suit, chaotic humor, and frequent breaking of the fourth wall. In Marvel vs. Capcom, he appears as a playable fighter who brings fast, unpredictable combat, acrobatic attacks, and comedic voice lines into the crossover battles. His role is primarily as a fan-favorite wildcard character, mixing brutal weapon-based offense with self-aware jokes and absurd behavior that contrast with the more serious tone of many other fighters.
