The Deadpool movies have portrayed many sides of the mercenary, from his humorous to his angriest. That said, there are still many sides that have yet to be touched on, including his desire to work in a team setting. From the first movie, Deadpool has always wanted to be a solo act but was forced to get help, whether it's joining Colossus or making a team like X-Force. But Deadpool 3 will see a new team-up that fans have long awaited, with Hugh Jackman's Wolverine returning in a comic-accurate suit.
