Cable is the founder of X-Force, a satellite team to the core X-Men superhero squad. Under Cable's guidance, X-Force was a hardline, paramilitary alternative to the X-Men's principled super heroics. Later, when Wolverine had taken over a new version of X-Force, the team became an assassination squad operating out of the shadows and included Deadpool as one of its members.

The introduction of Cable in Deadpool 2 will bring 20th Century fox one step closer to an X-Force spin-off movie. X-Force is a project that 20th Century fox has had in development in various forms for years. Now it falls to Deadpool 2 writers Rhett Reese and Paul Wernick to lay the groundwork.
"There is a responsibility we have to the X-Force universe, and I do think we will not disappoint the fans going into Deadpool 2 and then setting up X-Force and beyond," Reese tells Collider.
"We never want to let the tail wag the dog," Wernick says. "We want to tell the best Deadpool story we can. But I do think we have a responsibility to think about a larger universe in the way that Marvel does and start to put pieces in place. Some of these movies feel overstuffed and almost choking with the need to set up eighteen different things that pay off down the road, and we want to avoid that responsibility to the extent that it hurts us. We want to hint at things, we want to plan some characters, and we want to make some nods, but we're very, very cognizant about making sure that Deadpool is above all a Deadpool movie.
"Its purpose is not to set up X-Force," Reese adds. "It will likely set up X-Force, but the drive of the movie won't be our eyes on Movie 3."
