From the "Days of Future Past" storyline, Magneto is the one expected to be the medium from which Apocalypse will emerge. Moviegoers are advised to stick around during the end credits. For any superhero movie aficionado, that advice is moot.

The storyline for the Apocalypse movie is still undetermined, but speculation from the fanboy sites have suggested the "Age of Apocalypse" arc from the comic books.

The actual plotline from Days of Future Past has no direct links to Apocalypse, which is the challenge in making the story arc. However, if they can pull off how "X-Men: First Class" connects with the cast of the original X-men trilogy, they can make a viable story thread.

According to First Showing, they spoke to a X-Men movie insiders and they have hinted that Magneto is the link. It is further elaborated in this sequence.

[SPOILERS AHEAD]

The end credits scene for "X-Men: Days of Future Past."

"While using a well outside to get some water, the young Magneto sees something fall from the night sky and crash to Earth nearby. Upon inspecting the impact zone, he encounters what is described as an "alien form" who is "towering, terrifying, with a twisted metal face and dark pits for eyes." It's Apocalypse and he says, "I have crossed rivers of time to find you." Magneto asks, "Who are you?"

The alien responds, "I am your future." Suddenly Apocalypse merges with Magneto, who screams and blasts an insane amount of energy and shockwaves around him. This energy explosion levels everything around him, with a blast radius that goes for miles. As Magneto looks at what he's done, he has a realization of the power he now holds and a villainous grin begins to form before the film cuts to black."

While the scene gives a clue that the next movie will feature the "X-Men: First Class" Cast, it is still dependent on how DOFP unfolds. And of course, which of the actors are already signed.
