Although “Deadpool” is unlike any other Marvel movie out there, savvy fans still knew enough to stay in their seats for the end-credits scene that inevitably followed the film. The brief teaser had a lot going on in it, and some fans may have been left in the dark.

First of all, younger audience members may not have recognized the aesthetic of the final scene as being a parody of the 1986 classic comedy “Ferris Bueller’s Day Off.” In it, Matthew Broderick pokes his head out of a hallway and gives the audience permission to finally leave since the movie is over.

However, the “Deadpool” parody went the extra mile and had the hero, played by Ryan Reynolds, to tease a little bit of information about “Deadpool 2.” Before getting into the big announcement, it’s worth mentioning that a sequel hasn’t been officially confirmed yet. However, The Hollywood Reporter claims that 20th Century Fox has already green lit a sequel with writers Rhett Reese and Paul Wenick, who penned the script to the first movie. Whether it’s true or not, the "Merc with a Mouth" bet big on himself in the final moments of the film, telling audiences that there will be a new cast member from the comic books coming in “Deadpool 2.”

The hero announced that “X-Men” character Cable would make his on-screen debut, but said that he had no clue who would play the big part. For those unfamiliar with Cable, the broad strokes of his character are that he’s a mutant time traveler. Although no incarnation of him has been developed yet for film, most of the players that surround him have been. In the comics, he was the child of Cyclops who was sent forward in time to be raised by his half-sister. When he came of age, he took on the task of traveling back in time to try and stop the mutant Apocalypse, the cosmic entity that’s providing the big bad in 2016’s “X-Men: Apocalypse.” That should explain to the comic book novice what Deadpool was talking about when he mentioned time travel in the post-credits scene. Since completing his Apocalypse mission, Cable has clashed with Deadpool several times in the comic books, as fans found them to be a rather entertaining pairing.

“Deadpool," despite being a superhero movie about an immortal, was relatively grounded in reality. As a result, it might feel a little jarring for the sequel to have to set up time travel, alternate dimensions and a super-powered soldier with one eye from the future. Fortunately, the anti-hero might be able to leave all that heavy lifting for other movies.

According to Entertainment Weekly, before Cable meets up with Deadpool for whacky adventures, he leads a team of professor Xavier’s students called the New Mutants. That title just so happened to be put in the public’s mind last May when it was announced that “The Fault in Our Stars” director Josh Boone had been tapped to co-write and direct a "New Mutants" spinoff set in the “X-Men” universe that 20th Century Fox continues to expand.

With “Deadpool” calling Cable out, 20th Century Fox having brought Cyclops and Apocalypse to life and “The New Mutants” project on the way, it seems that “Deadpool” may have a pretty easy time getting the character on screen in the sequel. Fans will just have to wait for more news on "Deadpool 2" to figure it all out.
