Now that the Disney and Fox deal has been completed, will Deadpool join the Marvel Cinematic Universe, or will he be a one-man merc with a mouth? The deal between the two media giants has been in the works for more than a year, but now it's finally official, giving the film rights to the X-Men and the Fantastic Four franchises to Disney. Disney has promised to release all finished Fox projects including "X-Men: Dark Phoenix." The future of "New Mutants" is still being discussed. It's rumored that Disney will drop it on Hulu instead of through a theatrical release.

A "Fantastic Four," reboot is a strong possibility, allowing marvel the opportunity to introduce popular villains, including Doctor Doom and Galactus into the MCU. However, rebooting the X-Men is a little trickier, given the mutants will reshape that landscape of the cinematic universe. Because of that, it's probably going to be a long while before we see X-Men standing side-by-side with Spider-Man, The Hulk, or Black Panther.

Marvel Studios interested in lesser-known X-men

Kevin Feige has hinted at possibly introducing some of the lesser-known characters before moving on to the more popular mutants. But what does this mean for Deadpool? The popular '90s comic has become a hit since test footage leaked online, leading to Fox greenlighting a movie.

"Deadpool" grossed $783 million. "Deadpool 2" grossed $785 million. The character has come to make Ryan Reynolds even more famous. In the same way that Robert Downey Jr. has defined Tony Stark.

With a mouth that doesn't suit the family-friendly style of the Marvel Cinematic Universe, it's unclear what Disney will do with him.

Disney CEO Bob Iger has always insisted that Deadpool is welcome at the House of Mouse. As talks between Disney and Fox began, Iger addressed the possibility of an R-rated Marvel brand. He acknowledged the popularity of the Deadpool franchise.

Convincing Disney to release R-rated Marvel film?

Deadpool is not exactly a perfect fit for the MCU.

Kevin Feige previously said that R-rated Movies are still an option. Disney and Marvel have been focused on a family audience. Recent rumors about a Black Widow film becoming Marvel's first R-rated movie, are not true. Feige had previously said that they never even considered it. If Deadpool is allowed to continue, the studio would need to bring back the original cast that made the film a hit.
