So you've just seen "X-Men: Days of Future Past" and presumably, you loved it. The movie had a lot to like! After all the excitement ended, and the world was saved once again, we got a glimpse into Fox's next big mutant team up, "X-Men: Apocalypse". The big question for many fans is, who is the guy at the end of "X-Men: Days of Future Past"?
If you have been following comic book movie news, you probably know Fox is developing a sequel to DOFP called Apocalypse. The title definitely implies that the major X-Men character Apocalypse would be present! The man in the post credit sequence of DOFP is none other than Apocalypse himself. Apocalypse is a major X-Men villain, and marvel.com ranked him as the 3rd top X-Men villain, only beaten out by Sentinels and Magneto, both of which were featured in Days of Future Past.
Any fan of "X-Men: The Animated Series" will probably remember Apocalypse, and definitely will after a quick refresher:
The above scene gives you a small idea of who Apocalypse is, but let's go into detail further. Now obviously sometimes characters powers and origins are changed when they are transferred to the big screen, so just because it's been done that way in the comics for 28 years doesn't necessarily mean it will be anything like the movie adaption. Apocalypse is allegedly the first mutant. Born over 5000 years ago, he was left for dead as a child because of his physical appearance. He was raised under the principles of "survival of the fittest" in Egyptian tribes, he was known as En Sabah Nur. En Sabah Nur went through some heartbreak, and loss of loved ones, and he changed his name to Apocalypse. At some point in history, Apocalypse discovers alien technology left behind years ago, and enhances himself. Over the years, he's done battle with Thor, allied himself with Kang the Conqueror, and created another major X-Men villain, Mr. Sinister. Sinister was a British scientist who told Apocalypse he was a mutant. Fascinated by mutants, Sinister wanted to study them. Apocalypse turned Sinister into a mutant using his technology. Sinister goes on to be immortal and often tries to capture the X-Men simply to experiment on them.
Apocalypse has spent most of his life in hiding. He eventually becomes a major X-Men villain in the late 1980s, which is presumably when "X-Men: Apocalypse" will take place. His goal is mainly to destroy everyone, believing he is the rightful ruler of everything. Apocalypse created his Four Horsemen, which were four mutants turned evil by Apocalypse to help do his bidding. The most famous one is Angel, who is known as Death. I would assume the next movie will most definitely feature Horsemen of some kind. There is a very popular story called "Age of Apocalypse" where Apocalypse was not defeated by the X-Men, and the world is mostly a human-less post-apocalyptic wasteland. His powers are pretty extreme and nearly limitless. Apocalypse can control and molecule in his body. The best way I can describe it is a mix of Mystique, Darwin, and Mr. Fantastic. He can change his body into about anything. If he wants a chainsaw for a hand, he can do that. Maybe he wants his feet to be jet packs, no problem. He is known to have regenerative abilities not exactly unlike Wolverine's. He also appears to be able to absorb and project energy attacks, similar to Bishop.
Apocalypse has been featured in numerous TV series. He was a main antagonist in "X-Men: The Animated Series". He had a role in the next X-Men series, "X-Men Evolution", and again had a fairly prominent role in "Wolverine and the X-Men". He has been in numerous X-Men games, notably "X-Men: The Ravages of Apocalypse" and "X-Men Legends 2: Rise of Apocalypse".
