History WesternAnimation / XMenTheAnimatedSeries

* OutOfFocus: As the series progressed, Gambit, Jean, Cyclops, Storm and Jubilee appeared much less.

** "X-Ternally Yours": Bella and the Guild of Assassins are foiled, but Gambit realizes he's a StrangerInAFamiliarLand and severs all ties with those he knew.

On November 12th, 2021, Creator/MarvelStudios (yes, the studio responsible for the Franchise/MarvelCinematicUniverse) announced a {{revival}} of this series for Creator/DisneyPlus entitled ''WesternAnimation/XMen97'', originally planned for 2023 but subsequently delayed to 2024. Beau [=DeMayo=] (''WesternAnimation/TheWitcherNightmareOfTheWolf'') will serve as head writer. The series' original cast is set to return, with the exceptions of Creator/NormSpencer (Cyclops) and Creator/DavidHemblen (Magneto), both of whom died in 2020. Creator/AlysonCourt will also not return as Jubilee, who will instead be played by Asian-American actress Holly Chou at Court's insistence while Court is set to play a different character. In July 2022, a second season of the revival was confirmed.

** In the comics, Henry Gyrich is a massive jerk, and has been involved in some nasty business including the anti-mutant government scheme Project: Wideawake, but he's never appeared to be ''particularly'' against mutants and could genuinely claim that he was only ever serving his country. In the series, he's an anti-mutant zealot who reacts to a new age of human-mutant relations by [[spoiler: attempting to assassinate Professor X]].

* VillainousBreakdown: Graydon:

* ForWantOfANail: In the two-parter "One Man's Worth", it's shown that the death of Charles Xavier before he formed the X-Men, eventually led to human-mutant relations souring to the point of a full blown war taking place in the 90s, and in Bishop's time, Master Mold has all but dominated the world, and nearly wiped out all mutants.

* Jubilation Lee[=/=]ComicBook/JubileeMarvelComics, the teenage NaiveNewcomer who, at the beginning of the series, has just discovered she's a pyrotechnic-throwing mutant.

* ForcedAddiction: In the [[Recap/XMenS4E6SanctuaryPart1 two]]-[[Recap/XMenS4E7SanctuaryPart2 part]] "Sanctuary" storyline, during his time as ruler of Asteroid M, ComicBook/{{Magneto}} is repeatedly given power boosts by his second-in-command Fabian Cortez, ostensibly because his own powers were so heavily taxed by keeping Asteroid M functional. This ultimately leaves him heavily dependent upon Cortez, as his body becomes over-accustomed to the boosts.

* SetWrongWhatWasOnceMadeRight: In [[Recap/XMenS2E7TimeFugitivesPart1 "Time Fugitives, Part 1"]], Bishop's home time of 2055 has been ravaged by a synthetic plague, so he travels back to the 1990s to prevent it. Bishop's interventions exposes the creators of the plague and saves a few lives--but the X-Men all die in the process, and the vaccine for the plague is never invented, resulting in even more deaths than the original timeline. [[MeanwhileInTheFuture Meanwhile in the even farther future of 3999,]] Cable sees the disastrous results of Bishop's changes, and is horrified to realize the only way to save his future is to stop Bishop and let the plague ravage the past. However, in [[Recap/XMenS2E8TimeFugitivesPart2 "Time Fugitives, Part 2"]], [[spoiler:Cable manages to TakeAThirdOption. He intervenes to ensure that Wolverine specifically gets dosed with the plague. Wolverine's extreme HealingFactor allows him to recover almost immediately, and his antibodies allow the creations of the plague vaccine much sooner than in the original timeline]].

* ClothingDamage: Wolverine is almost guarenteed to lose his shirt every episode.

** In a very persistent inverted case, Storm's real name of Ororo Munroe is used maybe ''once'' during the show's entire run (the season 2 episode "Whatever It Takes).

** In "The Cure", the revelation that the scientist "Dr. Adler" is actually a disguised Mystique should come as no surprise to fans of the comics--he's named in honor of Mystique's lover, Irene Adler (AKA Destiny), who never actually appeared on the show.

** While it'd later be confirmed they're not founding members, Gambit, Storm, Wolverine, Rogue, and Morph are among the first X-Men we see. Likewise, Jubilee, Bishop, and Cable among others are depicted as meeting the X-Men earlier than they did in the comics.
** Beast in the comics started off relatively normal looking aside from oversized hands and feet before he gained his blue fur. Here, he already has the fur.

** Cable's son Tyler. In the comics he was an AntagonisticOffspring and eventually became a supervillain going so far as trying to follow in ''Apocalypse'''s steps. Here Tyler is a straight-up hero and he and Cable are very close. Probably {{justified|Trope}} via [[EvilTwin Stryfe]], whose actions caused their relationship to go sour in the original comics, being AdaptedOut.
** Instead of a psychotic monster, Proteus is just a confused child who only wants to see the wider world, meet his father, and be accepted by him. His BodySurf doesn't PossessionBurnout, either, for obvious reasons. Also, instead of a vicious rapist, Proteus's father is merely a selfish politician who embraces his son in the end.

* AdaptationalWimp: A downplayed example but, Omega Red has some of his usual powers removed in this version, most notably he normally emits some "Death Spores" which kill any non-superpowered people in a certain radius. Most likely this was done because they thought that would be [[{{Bowdlerise}} too gruesome for a kid's show.]] Writers attempted to counteract this by making him [[NighInvulnerability Nigh-Invulnerable]] even to Wolverine's Adamantium claws, with only subzero temperatures being able to slow him down.

** Raksor the Skrull and his Kree counterpart are absent from "The Dark Phoenix Saga". Raksor is replaced by the imperial guardsman Hobgoblin (as both were technically [[ComicBook/LegionOfSuperHeroes Chameleon Boy]] stand-ins), but nobody covers the part of the Kree observer.

** Ramrod is the only member of the Nasty Boys who did not appear in the show.

** There was a reason Cyclops and Havok's powers had no effect on each other when they fought in "Cold Comfort". They are brothers, but unlike the comics, they never find out they're related.
** The show doesn't really do a good of explaining exactly who Ms. Marvel is or why Mystique hates her so much. In the comics, Mystique started off as a Ms. Marvel villain, and was arguably her ArchNemesis. It was only after ''Ms. Marvel'' was cancelled that Mystique [[RoguesGalleryTransplant became a prominent X-Men villain]].

* AlmightyJanitor: A literal example in the "Beyond Good and Evil" four-parter, when Bishop is accompanied by a total nut, who reveals he takes care of the Axis of Time, to Bishop's incredulity. When everyone leaves and time is restored, he transforms into his true identity: [[spoiler:Immortus]].

* ArcVillain: Throughtout each season, there is a villain who serves as the main threat.

* AscendedExtra: Cameron Hodge starts out as some as aide to some guy calling himself "The Leader", who governed Genosha in the episode "Slave Island". He apparently survived the climax of that episode and became the chief antagonist of the two-parter, "The Phalanx Covenant".

* ClassClown: Bobby Drake aka Iceman is this to the point of Deconstruction. He was one of the original members of the X-Men, but his lack of discipline, irresponsibility, unwillingness to follow orders, and his jokester nature made him fall out of favor with Professor Xavier and Cyclops, whom he felt would never accept him despite his efforts. Eventually he walked out on the X-Men out of frustration and even years later Cyclops and Xavier would distrust him due to their past antagonism. In turn, Drake would refuse to re-join the term.

** Wolverine - who's often to hit first and ask questions later, and Beast, who prefers to reason his way out of problems before attacking.
** The temperamental Rogue - who hides her sense of isolation; and the calm and stoic Storm, who holds back the range of her emotions.
** The innocent Jubilee, who had loving foster parents, and wholeheartedly embraces the X-Men; and Gambit, who was forced by his guardians into a life as a thief, witnessed (and probably did) terrible things which gave him a touch of cynicism and hides his past from the team.

** Brother Reinhart in "Nightcrawler" who leads a mob to kill Nightcrawler and his brothers, whom he believed have been corrupted by the "demon". But after Nightcrawler shows him mercy after saving him from a fall and showed him what his actions have caused (burning the monastery), he falls on his knees and cries that he has "sinned". He later repents.

* AdaptationalAttractiveness: The Shadow King's human body. In comics he's fat and bald. In the series he's a handsome Egyptian with a beard. The animators based his character design on a later [[BodySurf host body]] of the Shadow King entity, Jacob Reisz, rather than [[FatBastard Amahl Farouk]], the body he was in when he was introduced in the comics (though [[ShrugOfGod perhaps not his original form]]).

** Kevin Sydney's codename was changed from "Changeling" to "Morph", in part because Creator/DCComics copyrighted it (''ComicBook/TeenTitans'' character Beast Boy was using it at the time). It's since been adapted for the ''ComicBook/AgeOfApocalypse'' and ''ComicBook/{{Exiles}}'' incarnations of the character.

Another animated series based on the X-Men comic, ''WesternAnimation/XMenEvolution'', was made in the early '00s, followed by ''WesternAnimation/{{Wolverine and the X|Men2009}}-Men'' in the late '00s. In 2015, this universe was revisited under the title ''ComicBook/Xmen92'' as part of the 2015 ''ComicBook/{{Secret Wars|2015}}'' event and returned as a full-fledged ongoing series as part of the ''ComicBook/AllNewAllDifferentMarvel'' lineup.

* AlternativeForeignThemeSong: The Japanese dub of ''X-Men'' not only has a different theme song, it completely reanimates [[https://www.youtube.com/watch?v=gfjAbXrvkFw the]] [[https://www.youtube.com/watch?v=_8HkDMht3d4&feature=related opening!]] It also uses a new [[https://www.youtube.com/watch?v=y9ZIleCnye8&feature=related ending]], which shows stills from the American comic.

* AlternativeForeignThemeSong: The Japanese dub of ''X-Men'' not only has a different theme song, it completely reanimates [[https://www.youtube.com/watch?v=gfjAbXrvkFw the]] [[https://www.youtube.com/watch?v=_8HkDMht3d4&feature=related opening!]] It also uses a new [[https://www.youtube.com/watch?v=y9ZIleCnye8&feature=related ending]].

* AdaptationalVillainy: Apocalypse is even more evil than usual in this version, going from TheSocialDarwinist to full-fledged OmnicidalManiac.

** The Phoenix and Dark Phoenix sagas were both shortened drastically. In particular, Jean never dies except for briefly at the very end of "The Dark Phoenix Saga", and the whole subplot with Cyclops marrying Jean's clone Madelyn Pryor, impregnating her with Cable, and then abandoning her for Jean, which drives Madelyn insane, is dropped entirely. The only time Cyclops and Jean's relationship is rocked during "The Dark Phoenix Saga" is when the unstable Jean sees Cyclops get an unwanted kiss from the overly flirtatious mutant nightclub singer ComicBook/{{Dazzler}}.
