Writers Rhett Reese and Paul Wernick have been all over the place following Deadpool’s substantial box office windfall. The two stopped by The Q & A podcast (tune in to about the 29-minute mark), and over the course of their conversation, the subject of which characters they included, and why, came up. There are only really two other X-Men involved, Colossus and Negasonic Teenage Warhead, who Reese said they included because of her name. They didn’t even know what her powers were, and changed them drastically. This alteration, however, was the one thing they needed Marvel to sign off on.
