Wade Wilson, known as Deadpool, is a mutant mercenary and anti-hero created by writer Fabian Nicieza and artist Rob Liefeld. He possesses an accelerated healing factor that allows him to recover from severe injuries, though it left him severely disfigured. Originally a professional criminal and assassin, Deadpool operates in morally gray areas, often taking contracts for payment while maintaining unexpected loyalty to those he considers friends. He is known for his irreverent humor, fourth-wall breaking tendencies, and unpredictable behavior. Despite his violent profession and chaotic nature, Deadpool has demonstrated capacity for heroism, such as when he betrayed the Collector to help his old friends Rogue and Gambit escape. His character is defined by the contrast between his brutal methods and his underlying humanity.
