Technically, Deadpool serves as both an X-Men and a New Mutants crossover, as it features Colossus from Professor X's original superhero team and Negasonic Teenage Warhead, one of the founding members of the later, younger mutant enclave. But fans want a true X-Men and Deadpool crossover, where the Merc with the Mouth joins the entire line-up of mutants in battle. That notion is still very much possible, according to X-Men: Apocalypse director Bryan Singer. Though, there's no telling when this may happen.

Singer, who has directed four of the six main X-Men movies, believes these mutants can stand tall alongside both Disney's MCU and Warner Bros.' DCEU, even though the X family hasn't yet been given a cool abbreviated name. This means the expanded X-Men universe will potentially see a lot of crossovers and tie-ins. As evident in the first Deadpool movie, which proved to be a blockbuster hit, becoming the highest grossing X-Men movie of all time. Of course 20th Century Fox is going to want to share the character.

But in the recent past, many of those individuals directly responsible for making Deadpool a success have hinted that Wade Wilson might be just a little too 'Meta' to side up against Wolverine, even though that exact thing already happened in the 2009 X-Men: Origins spinoff. Bryan Singer told Variety this about a possible X-Men and Deadpool crossover movie.

"[X-Men is] every bit as large [as DC and Marvel].And now that we've altered the timeline [with 2014's 'X-Men: Days of Future Past'], there are endless possibilities.If you take a character as irreverent and meta as Deadpool and connect him to something as grounded and serious as X-Men, you have to do it carefully and gently. When you drop them all in together it can be a disaster. That has to be done delicately, but there's plenty of room to do it."

Deadpool has racked up an unexpected and amazing $760 million at the global box office. And it finally comes home this month on Blu-ray and DVD. The raunchy R-rated superhero movie even earned more domestically than Batman V Superman. It's a no brainer that Deadpool needs to be utilized more in the future. Most likely, Deadpool will first show up in the planned X-Force movie, which follows a group of paramilitary superheros who embark on dangerous missions. Bryan Singer isn't only looking to the future in terms of X-Men movies, he also plans to expand this universe on the small screen with upcoming TV shows such as Hellfire and Legion. The director says this about widening the mutant universe.

"I think the underbelly [could be explored]. There's always something interesting about a school that's got a military aspect beneath its classrooms. Is there another layer to all of that? Is there another layer to the Hellfire Club? The idea of, 'Who's running the world?' - that's something that was touched upon in 'First Class' but has yet to be fully explored. It just has to be explored in a very gentle, methodical way. And I've seen it go haywire. I'm not going to be specific where I believe it has. The audience will tell you. But when it's done right, it all can connect."

It isn't known how directly Bryan Singer will be involved with the impending slate of X-Men movies and TV shows. There have been rumors that he plans to leave this world entirely along with Hugh Jackman, who has a cameo in X-Men: Apocalypse before his final performance as Logan in Wolverine 3 next year. Though, the director sounds too invested in what he's helped create to fully let it all slip from his grasp.

"When you spend nearly two decades in a universe, to simply say, 'I'm done,' or, 'I'm going to abandon it,' just wouldn't make sense to me. I'm very connected to this universe and a lot of these actors, and also the characters, whomever plays them. So never say never."

Along with the two planned small screen spinoffs, the next X-Men movie after Apocalypse will be Wolverine 3, which arrives March 3, 2017. It will be followed by the spinoff Gambit starring Channing Tatum, which was originally slated for release this October but has been pushed to an undetermined date. The New Mutants and X-Force movies are also swiftly moving forward, though no confirmed dates have been announced yet. And we will get Deadpool 2 in the next couple of years, which will first introduce Cable before he becomes the lead in X-Force. There is no telling whether or not a true Deadpool Vs The X-Men crossover movie will be announced in the next year or two. A Fantastic Four Meets the X-Men crossover was being discussed before the Fantastic Four reboot proved to be a massive bomb. At this time, the studio has not announced how it plans to move forward with The Fantastic Four franchise.
