Deadpool. Mercenary, assassin, sometimes good guy, the bane of his enemies and super annoying to his friends.
Deadpool was originally Wade Wilson, a former Special Forces soldier who became a mercenary. After falling in love with a prostitute named Vanessa, Wade discovered that he was suffering from terminal cancer. In desperation, he submitted to a sinister program patterned after the Weapon X program that gave Wolverine his adamantium skeleton and claws. There, Wade was subjected to torturous experiments designed to unlock any latent mutant powers. He was eventually blessed with limitless regenerative power, but his face was forever scarred by the experiments. He escaped, killed his captors, and set up shop as Deadpool. Now the Merc with a Mouth walks a dangerous line between good and evil, doing things that the heroes cannot do, while occasionally siding with X-men like Colossus and Negasonic Teenage Warhead.
In a universe of serious, somber superheroes, Deadpool is the trickster. He is funny, self-aware, and frequently breaks the fourth wall, talking directly to the audience and making fun of actor Ryan Reynolds’ career. He’s become one of the biggest hits of Fox’s superhero lineup and he’s been introduced to a whole new generation of fans.
