Deadpool (born Wade Winston Wilson) is a Canadian freelance mercenary who became a superhuman with an accelerated healing factor from the Mutant Workshop program.

Wade Wilson was a soldier and mercenary with enhanced reflexes and agility due to him being a mutant, putting him far beyond the average human.

  During the Vietnam War in mid-late 1973, a young Wade was a member of a black ops group called Team X under the command of William Stryker. The team also included James “Logan” Howlett, Victor Creed, Christopher Bradley, Agent Zero, John Wraith, and Fred Dukes. He did as his leader ordered when it came to killing people, with Stryker even going so far as claiming that Wade would be the perfect soldier if it weren’t for his inability to stop talking.

  Six years later, after Team X broke up, Wade was captured and taken to Stryker’s base at Three Mile Island, where he was experimented on for the Weapon XI project. He was the first Team X member to be killed by Victor, and his body was used as a catalyst for the Weapon XI project. With Victor’s help, Stryker gathered and collected the DNA from mutants whose powers could be used collectively within one body without destroying it, with Wade being the host body. By then, Wade was gone, and was now known as Weapon XI, “The Mutant Killer” – Deadpool (as Stryker explained – a “dead” mutant who had other powers “pooled” up into him). Stryker also seals Wade’s mouth and gives him an adamantium skeleton.
