Despite bringing the Merc with the Mouth into the MCU, Deadpool and Wolverine devoted a significant amount of time to Earth-10005, also known as the X-Men Universe.
 
Wade Wilson and Logan became (unwilling) best friends at the end of the film, and it is now anticipated that we will see them together in Avengers: Doomsday in december of next year. But if Ryan Reynolds had his way, we would have said goodbye to the anti-hero in the threequel forever. The actor and writer acknowledged that he thought about ending Deadpool's adventures in the MCU just as they were beginning in an interview with Scott Mendelson on The box office podcast.


"There’s always the thought of killing Deadpool in the last one," Reynolds admitted. "Again, it’s like listening to the movie. Me, Shane Reid, Dean Zimmerman, and Shawn Levy must have reworked that third act for 45 days straight. Finally figuring it out — I am such a needle-drop person, but I’m really working hard to embrace score."

"It was Rob Simonsen who really helped us get there by blending score, needle drop, and all these things that gave you that feeling we were working for."

"Studios are like, of course, it’d be fun to play around with this guy in the future, because he’s a cheat code," the actor continued. "He can say things that everyone might be thinking, and it gets you out of trouble." He'd later point out that he was ultimately happy Disney didn't let him kill Deadpool because he "loves playing him."


A supporting role for Wade Wilson would be part of the project, which is distinct from the X-Men relaunch that Michael Lesslie is writing for Marvel Studios.  Whether the project will be completed is uncertain because Reynolds is now working separately from the studio.  But most people think it's an X-Force project.
 
 On social media, there are also rumors that Reynolds' Deadpool, Hugh Jackman's Wolverine, and Zazie Beetz as Domino have already been spotted on the Avengers: Doomsday set.  For the time being, we would take that with a grain of salt. They might have also served as stuntmen or stand-ins, with the actors scheduled to film their roles later.
