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 Senator Kelly's assassination. Bishop plays the role of Kitty Pryde in the adaptation—albeit traveling 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-Men's interference revealing that Mystique had killed Senator Kelly while in Gambit's appearance to try and frame the X-Men.

• The series Wolverine and the X-Men has a similar storyline, in which 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 "Age of Apocalypse" appeared in its place. The series stopped production before the second season revolving around this could be made.

• A Days of Future Past incarnation appeared in The Super Hero Squad Show episode "Days, Nights, and Weekends of Future Past".

• A Madland level based on "Days of Future Past" appears in the Ultimate Spider-Man episode "Game Over". Mutant Arcade designs the level under the basis of Sentinels being used to destroy mutants. The scenario features a shot of Wolverine being blasted by a Sentinel in an homage to the cover of Uncanny X-Men No. 142.

• Hulk and the Agents of S.M.A.S.H. features a five-part episode entitled Days of Future Smash, which consists of the Hulk chasing the Leader throughout numerous events of time and space. The episode's title is a reference to Days of Future Past.

• A future resembling that in Days of Future Past can be briefly glimpsed in the Moon Girl and Devil Dinosaur episode "Skip This Ad...olescence", as Moon Girl is accidentally sent to her future body by her time traveling app. The scene itself homages the cover of Uncanny X-Men #141. Executive producer Steve Loter later hinted on his Twitter account that the scene foreshadowed elements from the series' planned storyline.[10]

X-Men: Days of Future Past is a sequel to First Class. Numerous actors from the franchise returned, including Hugh Jackman, Halle Berry, Ian McKellen, Patrick Stewart, James McAvoy, Michael Fassbender, Anna Paquin, Elliot Page, Shawn Ashmore, 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 who is actually sent backward in time 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.[11] 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 Sentinels capable of adapting to any mutant power. After Shadowcat learns how to use her abilities to 'phase' someone into their past self, Xavier and Magneto decide to have her send someone back in time to the year 1973 to prevent Mystique from killing Trask, with Wolverine being selected as he is the only one who can survive the process due to his regenerative healing factor. Upon arriving in 1973, Wolverine locates the past versions of Xavier, Hank McCoy, and Magneto and convinces them to help him prevent their extinction. Although Magneto nearly jeopardizes the plan when he tries to kill Mystique and takes control of the Sentinels as part of his own plan to save the mutant race, Xavier is able to convince Mystique to spare Trask, resulting in her being publicly shown defending President Richard Nixon from Magneto. As a result, Mystique is hailed as a hero, the Sentinel program is scrapped, and Trask is arrested for selling his designs to foreign nations. The film ends with Wolverine waking up in a revised, idyllic future in which the war with the Sentinels never happened and all of the X-Men are still 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, a mobile app developer, released The Uncanny X-Men: Days of Future Past for iOS and Android devices. The game is a 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.[12]

The ending of the X-Men Origins: Wolverine video game is set in a not so distant future in which Wolverine (in an X-Men costume) breaks free from captivity by Bolivar Trask to discover Sentinels have taken over the world.

A novelization of the comic version of "Days of Future Past" by Alex Irvine was released in May 2014 by Marvel Comics that tied into the release of the film, X-Men: Days of Future Past. It essentially follows the plot of the original comic storyline, but with two particular changes to the events set in the future: Magneto survives the escape of the Sentinel camp and hides until his powers are restored to the point that he can annihilate the remaining Sentinels, and Kitty is conscious in the body of her future self rather than remaining comatose until she is returned to her own time.
