He showed up once Deadpool put an ad for X-Force members, and was immediately recruited. He died alongside all the other X-Force members, but Deadpool used time travel to prevent his death. He is now one of the current members of X-Force, alongside Deadpool himself, Colossus, Negasonic Teenage Warhead, and Domino. It's unknown if he has any superpowers.
