"Days of Future Past" is a storyline in the Marvel Comicscomic bookThe Uncanny X-Men issues #141-142, published in 1981. It deals with a dystopian future in which mutants are incarcerated in internment camps. An adult Kate Pryde transfers her mind into her younger self, the present-day Kitty Pryde, who brings the X-Men to prevent a fatal moment in history that triggers anti-mutant hysteria.
The storyline was produced during the franchise's rise to popularity under the writer/artist team of Chris Claremont, John Byrne and Terry Austin. The dark future seen in the story has been revisited numerous times, and was adapted into the 2014 feature film X-Men: Days of Future Past. In 2001, fans voted the first issue of this storyline the 25th greatest Marvel comic.
The Official Handbook to the Marvel Universe: Alternate Universes 2005 gave the numerical designation for the original "Days of Future Past" timeline as Earth-811 in the Marvel Multiverse.
The storyline alternates between the present year of 1980 and the future year of 2013. In the future, Sentinels rule a dystopian United States, and mutants are hunted and placed in internment camps. Having conquered North America and hunted all mutants and other superhumans, the Sentinels are turning their attention to the rest of the world. On the eve of a feared nuclear holocaust, the few remaining X-Men send Kitty Pryde's mind backward through time, to possess the body of her younger self and to prevent a pivotal event in mutant–human history and the cause of these events: the assassination of Senator Robert Kelly by Mystique's newly reassembled Brotherhood of Evil Mutants.
Working with the present-day X-Men, Kitty Pryde's future self succeeds in her mission and is pulled back to her own time, while her present-day self is returned with no memory of any interim. The world of 2013 is not shown again in this story arc; the present-day X-Men are left to ponder whether their future dystopia has been averted or simply delayed.
Rachel joins the European mutant team Excalibur, whose series twice revisited the "Days of Future Past" timeline. The first time was in a story by Alan Davis entitled "Days of Future Yet To Come," in which a time-traveling Excalibur and several Marvel UK heroes overthrow the Sentinel rulers of future America. This storyline also reveals that Excalibur's robotic "mascot" Widget had been possessed by the spirit of the future Kitty Pryde.
A similar but distinct reality is seen in a vision by her teammate Captain Britain. This story, "Days of Future Tense," reveals the final fate of that timeline's Excalibur team.
A prelude to "Days of Future Past" was produced in a three-part mini-series entitled "Wolverine: Days of Future Past". This three-issue mini dealt with ramifications between the catalyst for the creation of the alternative future up until the main storyline in Uncanny X-Men 141-142. The prelude explains why Logan leaves for Canada and why Magneto is in a wheelchair in the main two issue story.
Another view of this reality was presented in the second issue of Hulk: Broken Worlds. A short story, "Out of Time," examines the life of Bruce Banner (the Hulk) in a Sentinel prison camp.
A sequel based on the original storyline, "Years of Future Past", will be released in Summer 2015.
In other media
A novelization of the comic version of "Days of Future Past" by Alex Irvine was released May 2014 by Marvel Comics that tied into the release of the film, X-Men: Days of Future Past.
The "Days of Future Past" storyline was adapted in the X-Men animated series. The storyline concepts were combined with another alternative future story—that of Bishop and the idea of a traitor within the ranks of the X-Men, though Mystique is still responsible for Kelly's assassination. Bishop plays the role of Kitty Pryde in the adaptation- albeit travelling completely back in time instead of just projecting his mind into his past self- while the 'traitor' is 'revealed' to be Gambit, with the X-Mens' interference revealing that Mystique had killed Kelly while in Gambit's appearance to try and frame the X-Men.
The series Wolverine and the X-Men has a similar storyline, where Professor X is in a coma for 20 years, and awakens to find that the mutants are imprisoned by the Sentinels. He telepathically connects with the X-Men of the past to try to prevent that future from happening. By the end of the first season, the Sentinel-dominated future was averted. However, a future based on the Age of Apocalypse appeared in its place.
A Madland level based on "Days of Future Past" appears in the Ultimate Spider-Man episode "Game Over". The scenario features a shot of Wolverine being blasted by a Sentinel in an homage to the cover of Uncanny X-Men #142.
X-Men: Days of Future Past is the sequel to First Class. Several actors from the past of the franchise returned, including Hugh Jackman, Halle Berry, Ian McKellen, Patrick Stewart, James McAvoy, Michael Fassbender, Shawn Ashmore, Anna Paquin, Ellen Page, Daniel Cudmore, Nicholas Hoult, Jennifer Lawrence, and Lucas Till. Newcomers Peter Dinklage, Omar Sy, Adan Canto, Fan Bingbing, Booboo Stewart and Evan Peters were also signed to play Bolivar Trask, Bishop, Sunspot, Blink, Warpath and Quicksilver, respectively. Although Wolverine is the one to actually return to his "younger" body, director Bryan Singer described Pryde as the prime facilitator and it is Pryde's phasing ability that enables time-travel to happen. In this film, the catalyst for the Sentinel-dominated future was Mystique's assassination of Bolivar Trask and her subsequent capture, with analysis of her DNA allowing humanity to devise a new form of Sentinels that can rapidly adapt to mutant powers. After Shadowcat learns how to use her abilities to 'phase' someone into their past self, the surviving mutants decide to send someone back in time to the 1970s to prevent Mystique from killing Trask, with Wolverine being selected as the process is so physically dangerous that he is the only person who could survive the strain. Although the past Magneto nearly jeopardizes the plan when he tries to kill Mystique and take control of the Sentinels to attack humans, Wolverine is able to work with the younger Xavier and Hank McCoy—including one scene where he acts as a psychic 'bridge' so that the younger Xavier can communicate with his future self—to give the young Xavier a chance to talk Mystique down, resulting in her being publicly shown defending President Richard Nixon from Magneto and Trask being arrested for trying to sell his plans to foreign powers. The film ends showing Wolverine waking up in a changed future where there are no Sentinels and the previously-deceased Scott Summers and Jean Grey are once again alive.
Ultimate Marvel vs. Capcom 3 has a "Days of Future Past"-inspired stage serving as an alternative to the standard Metro City stage, with an "Apprehended"/"Slain" poster similar to the famous one, featuring characters from both Marvel and Capcom that starred in Marvel vs. Capcom 2: New Age of Heroes, but did not return for the Marvel vs. Capcom 3 games. Taking the place of the playable Wolverine is Mega Man.
To coincide with the release of the film, GlitchSoft, an mobile app developer, released The Uncanny X-Men: Days of Future Past for iOS and Android devices. The game is side-scrolling 2-D action adventure, with a storyline closer to the original comic book, than the one portrayed in the film. Initially players will be able to control Wolverine, and as they advance further in the game, they will be able to choose between Kitty Pryde, Colossus, Scarlet Witch and Cyclops, with Storm, Polaris and Magneto announced as additional characters, each one with different powers and abilities, which is upgradable as the player progress in the game, by obtaining experience points.
In "Genesis", the first episode of the television series Heroes, the character of Hiro Nakamura cites Kitty's traveling through time as teaching him about the concepts of time travel. Hiro states that the comic taught him that time is a circle, even though it actually insinuated that time branched. The episode "Five Years Gone" was a further homage to the story, featuring Hiro and his friend Ando travelling into a future where New York has been destroyed and people with abilities are being hunted, forcing them to travel back into the past to prevent the original explosion.
