History Fridge / XMenDaysOfFuturePast

* Hell, Past!Charles ''entire character arc'' fits perfectly alongside the events of First Class. Some fans were confused about the ease with which Charles recovered (mentally) from the [[BreakTheCutie devastation and loss]] that he went through at the climax of First Class. It turns out, ''he didn't''. He likely internalized most of his pain, causing him to [[DespairEventHorizon break completely]] when he lost everything else.

** Not necessarily, pretty much every incarnation of the X-men establishes some sort of dark future. As Beast states in the 90's series if you destroy one of evil's forms it will likely just take a different form. It's pretty much canon that some form of dark future will happe in the near future, the trick is making it a dark future that can be endured.

* Dwarfism is a genetic mutation, that means Trask is a mutant who is hunting other mutants

** Another possibility: Xavier is aware of the events at Alkali Lake and that Stryker will be plotting against them and uses the captured Magneto to not only get information about the mansions defenses but also to catch Xavier and Scott. So if things get bad enough that they start repeating (which they might have given Rogue's presence and interference in ''' The Rogue Cut'''), Xavier could avoid the whole situation by not handing Magneto to the police at the end of the first movie.

* Rogue's power absorbs memories. So when Iceman kissed her, she got the memories of everything he lived through. So she not only learnt how things have gone to hell after whenever she went under, she finds out the boy she loved is in a serious relationship with someone else, and probably gets some of those memories in the process. Not to mention, absorbing Kitty's powers probably brought some of ''her'' memories over as well. Rogue just does not catch a single break.

** Alternatively, she is still phasing, she's just learned a [[HeartIsAnAwesomePower new way to do it]]. Instead of phasing people into objects, she's phasing them into themselves at different points in the timeline For a longer explanation see here:[[note]] In the comics, Kitty's explicitly and implicitly been able to leave things inside of other things as she phases, usually using it to kill people. In this instance however, she's phasing a person's intangible consciousness (similar to how she can "walk on air" using her phasing powers to phase through intangible gases) through their different iterations, "leaving" the older consciousness inside the younger one. In order to do this, she obviously must pass through the only connection the "past" consciousness has to the "present": all of the consciousnesses between those two points in time. This is why the film describes it as "stretching", and why the subject retains their memories of the future into the past and the altered timeline. Their consciousness is phased through every point in their timeline, pulled like quantum taffy to get to the point in the past where it can be useful. Now obviously with there being a theoretically infinite number of points between two markers on a timeline, the number of consciousnesses adds up fast (hence why it hurts and why normal people can only go back a few days at most, while Logan's healing factor allows his "taffy" to repair itself as it gets stretched). However, this explanation not only fits all the descriptions given in the film, but also justifies the SanDimasTime and RippleEffectProofMemory experienced by the user. [[/note]]]]

* As all CosmicRetcon stories, this one has a huge ProtagonistCenteredMorality. The very idea of a world that ceases to be, to be replaced by a completely different one, is a huge horror if you stop to think about it for a moment. We have seen dead people who are now alive, and dead couples witch are reunited again, but things may be different elsewhere. What about the people who met and loved in the old timeline, and never met in the new one? What about the children of such unions, who would simply cease to exist? Even more, a cosmic retcon does this ''to the whole universe'', not just to Planet Earth, and [[ButterflyOfDoom who can predict how other worlds would be affected?]]

* ComicBook/{{Quicksilver}} doesn't seem to know SelfDemonstrating/{{Wolverine}}, suggesting that they met in the future, perhaps after the time of any of the previous films. And Wolverine actually confirmed that he only met Peter when the latter isn't so young anymore. Rather depressingly, his absence from the future scenes in ''Days of Future Past'' can be explained by him being among the mutants who've been killed off by then.

** It may or may not be intentional by the writers, but Xavier's emotional state in ''First Class'' and ''Days of Future Past'' works well as a metaphor for America's mindset during the time period the movies depict. In 1962, the character's optimism is an extension of the hopeful outlook President Kennedy's administration tended to exude, whereas Charles' melancholia in 1973 is not unlike the general malaise American citizens felt while under the shadow of the UsefulNotes/VietnamWar. Xavier's descent into despair began in 1963, which is the same year Kennedy was assassinated--the end of "Camelot" [[note]]Kennedy's presidency is sometimes called this[[/note]] parallels the end of Professor X's school. At least in the AlternateTimeline, Charles starts to piece himself together again shortly after the Paris Peace Accords are signed.

* Trask's idea of using Mystique's DNA to benefit his ''most certainly mechanical'' Sentinels might sound farfetched, but the idea somehow lasted into the BadFuture, where the "Nimrods" somehow exhibit Emma Frost and Darwin's abilities. One even sprouts claws like Wolverine!
** The Sentinel actually displays [[http://vignette3.wikia.nocookie.net/xmenmovies/images/8/8a/YurikoWickedNails-X2.png Lady Deathstrike's claws,]] not Logan's.

* It seems a little OutOfCharacter for Charles to suddenly hate and suppress his mutant powers, but consider his situation. Not only was his telepathy affected by his paralysis, but the overall attitude and minds of people around him has probably gotten a lot darker and more cynical. It was most likely much more enjoyable to be a telepath during the more positive early 60's than the negative and depressing early 70's. Not to mention the rather horrifying experience with Shaw and the coin, thanks to his powers. It's also heavily implied that due to his [[BreakTheCutie mental state]] ([[{{WMG}} and maybe his powers becoming stronger in the decade gap]]) he can't block out the voices anymore. Previously, he'd had to concentrate to hear thoughts, but now he just hears everyone within a certain range. And since [[spoiler: he started hearing them while in an isolated mansion]], it's a pretty big range.

** Although that could be rectified by the presence of a certain pair of powerful telepaths who knew their Logan well, and could possibly merge what they knew of him with the memories of the Logan that we know.

* Charles' breakdown when he first tries to use Cerebro is actually terrifying when you think about how many people were screaming in agony, and ''especially'' when you think about older!Charles mentioning to Logan in earlier movies that if he concentrates too hard or is disrupted during the process that he could kill them all. Seeing how unstable past!Charles was at this point, it isn't hard to imagine that something really bad could've happened if he hadn't taken off the helmet or gotten it together.
