[[folder:[=YMMVs=] for the X-Men comics:]]
* AcceptableTargets: Creator/BrianBendis and Craig Kyle to some degree, the former for his habit of using beloved C and D-list characters as expendable cannon fodder and the latter for unfailingly plugging his CreatorsPet X-23 front-and-center for ''anything'' he writes. Creator/ChrisClaremont gets this too sometimes for his [[AuthorAppeal very blatant love]] for certain fetish tropes, but above them all, the undisputed AcceptableTarget king? '''Chuck Austen'''. Just make a drinking game out of how often you'll seem him referred to as a "writer" with the quotes included, or otherwise disparaged. And unlike any of the above examples, there's pretty much ''no one'' coming to his support. His run really was that [[FanonDiscontinuity hated]].
* AdaptationDisplacement: Azazel and Toad have both been largely displaced by their respective film adaptations, both of which are generally preferred over their original incarnations. William Stryker is a curious example in that his original incarnation wasn't ''bad'', and is still regarded well as a villain, but has been overshadowed by his film incarnation thanks to his being one of the most recurring villains across all nine films (only Magneto and Mystique have made more appearances).
* {{Anvilicious}}: The anti-bigotry message that has always pervaded every fiber of ''X-Men'' is definitely a case of SomeAnvilsNeedToBeDropped, but under bad writers, it can be taken to laughable extremes.
* ArcFatigue: A common complaint. Every time the X-Men seem to be getting close to having mutants and humans coexisting, the ResetButton gets smashed so the anti-bigotry Aesop can continue being bashed into the readers' skulls.
* AuthorAvatar: Havok was unfortunately reduced to one for the Chuck Austen era, as the character reminded Austen of himself.
* BaseBreaker: Two main ones, on opposing sides. You either think Wolverine's the most badass and complex creation to come out of comics and Cyclops is a douchebag boring whiner who would be better suited as a villain, or that Wolverine is overhyped, overpowered, and a real dick, and Cyclops is mishandled, considerably badass, and one of the most complex characters in the comics. Now, combine that with RunningTheAsylum, and we get some truly EpicFail stories and OutOfCharacterMoment stories. Wolverine is actually listed as both an EnsembleDarkhorse ''and'' a CreatorsPet on [[Wiki/TVTropes This Very Wiki]].
** TakeAThirdOption: Or you think both characters are annoying and wish they would just go away. Or, somewhat less commonly, you think both characters are good and make decent Rivals for one another.
** Apocalypse is another big one, and it's one that seems very dependent on ''when'' you started following the comics. Fans who started following the comics around the time he was introduced likely think he's an incredibly badass villain, one of the all-time greats and easily the biggest threat to the X-Men, with a neat backstory and some pivotal stories to boot. Fans who started following significantly before or after his introduction tend to consider him a laughable VillainSue who, despite his [[SuperpowerLottery ridiculously unlimited powers]] and massive advantages, hasn't actually accomplished anything besides giving the heroes more powers, with a look ripped off from ComicBook/{{Darkseid}} and ComicBook/{{Thanos}} to boot.
** While not strictly speaking an X-Men villain, Thanos is this to a segment of the X-Men fandom for the ''exact same reasons'' described above for Apocalypse: laughably VillainSue, StoryBreakerPower with nothing to show for it, a lamer proto-version of ''their'' villain of choice and... [[BaseBreaker yeah]]. The rivalry between Apocalypse and Thanos fans, while simmering in the background compared to the front-and-center Cyclops VS Wolverine argument, is most definitely this.
** A new one has appeared as of the revelation of the ''AllNewAllDifferentMarvel'' line that [[spoiler:the Terrigen Mists are now lethal to mutants for ''some reason'', they have decimated mutants back down to an endangered species, and Cyclops has done ''something'' (that will be an ongoing mystery) to piss off the world back into "Kill All Mutants" mode-and ''this'' has made whichever mutants (that aren't the X-Men) that are still alive to pull stakes and get the hell out of Dodge]]. The fact that this [[YankTheDogsChain yanks the dog's chain]] of the ending of ''ComicBook/AvengersVsXMen'', [[spoiler:turns Cyclops into an ''even bigger'' douchebag after A.V.X. turned him into a pariah-seeking terrorist and arcs like ''ComicBook/BattleOfTheAtom'' showcased some amount of TheExtremistWasRight]] and seriously disconnects the readers from any supposed connection with mutant hood (it's supposed to stand in for any persecuted minority, but [[spoiler:becoming a ''nearly-extinct'' minority ''twice in a row'' with only a year or so of breathing time at the most]] seriously kills the WillingSuspensionOfDisbelief) has caused many people to decry the storyline for DarknessInducedAudienceApathy, while others are accepting of the new story set-ups despite of what is still an excess. [[spoiler:There is also the discussion whether this whole situation, rehashing of post-M-Day as some people seem to think it is, is just more fuel to the fire Marvel seems to be pushing on to people of accepting The Inhumans as the new "misunderstood and loathed yet {{Badass}} superhuman species" ''du jour'' (and with ''that'' there is massive discussions about ExecutiveMeddling that are better off discussed elsewhere).]]
* CanonSue: Wolverine, at least in recent years, when his former fans have became writers at Marvel. Its not usually so bad when the writers instead focus on other characters, but sometimes it can be quite extreme.
** As Wolverine's OppositeSexClone, it's perhaps not a surprise that X-23 falls into this too. Run, don't walk, away from any issue [[WriterOnBoard her creator]] Craig Kyle has penned.
* CompleteMonster: [[Monster/XMen See here.]]
* CrazyAwesome: Dr. Nemesis the wisecracking, LargeHam MadScientist and NaziHunter who is apparently immortal.
* CreatorsPet:
** Nurse Annie Ghazikhanian in ''Uncanny X-Men''. Universally maligned "writer" Chuck Austen introduced the single mother/apparent expert in mutant physiology shortly into his equally despised run on ''X-Men''. WordOfGod stated she was based on Austen's real-life wife, never a good start. He quickly made her the inane central character in many of his story lines. This usually included:
*** Vapidly gossiping about sexy men with once-intelligent characters Husk and Northstar.
*** Throwing tantrums/acting holier than thou during battles and various X-Men crises.
*** Dispensing shallow advice to other characters on their "romantic woes."
*** Wrapping bandages around injured characters' heads (regardless of their actual injury)
*** Apparently boning Iceman for no apparent reason.
*** Annie is mostly remembered for her creepy relationship with Havok, which started as a crush when she was caring for the longtime X-Man whilst he was in a comatose state. Once revived, Alex showed an immediate and unfounded attraction for Annie also. It was eventually revealed Annie's equally creepy mutant son Carter had been setting the two up on 'psychic dates' for months, allowing Austen to place the two characters in a relationship without needing to bother about annoying things such as context or developing a rapport between the characters. To further infuriate and confound readers, Austen also depicted Havok's longtime partner Polaris as an insane, homicidal, bitchy ex to further drive home the point that Annie was The Virgin Mary and Gandhi rolled into one.
*** Fan reaction to Annie (and Austen's run in general) was overwhelmingly negative, a fact that the writer dismissed as unreasonable "trolls". With his final story arc with the X-Men franchise, Austen wrote Annie and Carter out of the X-Men books. The pre-Austen Polaris/Havok relationship was restored in time and Annie only made a single ''cameo'' nearly ten years ago.
** [[Comicbook/{{X23}} X-23]] enjoys her fair share of this too, particularly whenever Craig Kyle is around. Being a teenage OppositeSexClone of Wolverine, she is everything everyone hates about him with very few of his redeeming qualities like wisdom and compassion. Instead, she comes across as an antisocial JerkAss, and yet the writers fight themselves over who puts her in what. Her role in ''New X-Men'' in particular, once her creators Craig Kyle and Chris Yost took over the title, you could be forgiven for thinking was written by a thirteen-year-old girl. She's portrayed as having NewPowersAsThePlotDemands, usually something related to animalistic senses, that enable her to figure things out before anyone else, as well as ten times the competence of the other kids with none of their charm coming with the territory of being inexperienced teenage superheroes. As the final punch to the gut, she hooks up with the [[DracoInLeatherPants hot bad boy character]] after his original love interest is [[PutOnABus clumsily written out]]. And it didn't do her any favors that the ''original'' main characters of the series were either unceremoniously [[DroppedABridgeOnHim killed off]], [[PutOnABus written out]] or {{demoted to extra}} to make room for X-23 being the primary focus. This is ironic, given that she was initially an EnsembleDarkhorse when she originated on ''WesternAnimation/XMenEvolution''. Perhaps it's the fact she has poor characterization these days while being a ''regular'' (always a failure of a combination for any character).
* DarknessInducedAudienceApathy: Let us be honest, they will ''[[StatusQuoIsGod always]]'' be "feared and hated." Any attempt at them improving their lot in life will ''always'' be at risk of [[YankTheDogsChain being demolished]] by the next [[RunningTheAsylum author who wants to change things]] or [[ExecutiveMeddling an editor that wants to change things]], and ''anybody'' you like [[AnyoneCanDie is most probably gonna kick the bucket at some point]] (and the question of [[DeathIsCheap when they will come back]] being pretty much up to said writers, editors and which VocalMinority is loudest). And InUniverse reasons for this happening... someone will become a {{Jerkass}} and ruin everything and some villain will always come along to try and see if he can exterminate the "mutant menace" when [[TheWorldIsAlwaysDoomed the literal armies of mutant haters that came before them]] could not.
** This is actually acknowledged and played with in ''ComicBook/BattleOfTheAtom''; [[spoiler: Beast's]] future self became fed up of fighting for the X-Men after the first mutant President is assassinated, making him hit a DespairEventHorizon as he realized that they'll likely never, truly, be accepted. When the present day X-Men talk to the future team about this, and are clearly shaken by this reality, they assure them that things ''will'' get better, but at their point in time they still have time to go.
* DesignatedHero: In the early comics, Xavier could give this impression, with his habit of keeping secrets and insisting others do the same painting him as a far more morally-ambiguous figure than Lee and Kirby intended him to be. Later writers made this an actual character trait of his, and one that he is called out on and has to atone for.
** In recent years, either (or both) Cyclops and Wolverine have became this, depending on your opinion. Either, Cyclops has became an extremist who refuses to accept responsibility and justifies his actions with weak excuses, or Wolverine has became a hypocrite who would rather pick a fight with his allies then actually deal with the bad guy, and often wastes time doing so and get incredibly douchey in his arguments despite supposedly being who we're supposed to side with. That's all that should or needs to be said.
* DieForOurShip: Every corner of the Emma Frost/Scott Summers/Jean Grey/Logan love square has its shippers and detractors. Same for Rogue/Gambit and every relationship here.
** Jason Aaron, the writer of ''Wolverine and the X-Men'', has been accused of doing this recently. After turning Colossus into the Juggernaut, resulting in Kitty breaking up with him... for some reason, he had Kitty, when she joined Wolverine, get together with Iceman, despite them never being depicted that close in the main comics. Likewise, when he broke up ComicBook/BlackPanther and Storm in ''ComicBook/AvengersVsXMen'', he had Storm migrate to his book and recently had her get together with Logan (though, at least this one made ''some'' sense).
* DorkAge: The X-Men have run for over fifty years, meaning everyone will have at least one period they consider an irredeemable DorkAge (except ''maybe'' the Claremont/Byrne run).
** The most commonly regarded nadir for the X-Men titles is everything from the end of Operation Zero Tolerance, to the start of the [[Creator/GrantMorrison Morrison]]/[[Comicbook/XForce Milligan]]/[[Creator/ChrisClaremont Claremont]]/[[Creator/JoeCasey Casey]] era.
** For some people, Morrison's run. This is a ''very'' BrokenBase though, with many others regarding it as one of the best, so we'll just leave it at that.[[note]]And of course within Morrison's run you have people who like one part but not another, et cetera, particularly when ''Planet X'' gets mentioned.[[/note]]
** Perhaps the one tenure that ''everybody'' regards as a DorkAge can be summed up with one name: Chuck Austen. Just see CreatorsPet above for an idea of how people felt about his time on ''Uncanny X-Men''. (That said, it does have ''some'' good points - many people thought Juggernaut's HeelFaceTurn, which was later reversed, wasn't actively terrible, at least.)
** The M-Day era, often regarded as heavy-handed ExecutiveMeddling from editorial, and steadily undermined for years by writers before it was eventually properly reversed.
* DracoInLeatherPants: ''Magneto''. There's ''many'' times where fans declare him to be right over the X-Men even when he's trying to genocide humanity. Not helped by the fact that Magneto has currently pulled a HeelFaceTurn and is trying to redeem himself.
** Sabretooth also gets his fair share of this, especially post-''Film/XMenOriginsWolverine''. The character is probably one of the most loathsome CompleteMonster villains the X-Men have ever faced, yet fans ([[RunningTheAsylum and writers]]) bend over backwards to give him FreudianExcuse after FreudianExcuse.
* EnsembleDarkhorse:
** In recent years, the writers have a tendency to take a shine to a particular X-Kid and promote them to the main cast or recurring character status. For Mike Carey, it's Trance. Warren Ellis has Armor. Craig Kyle and Chris Yost have Elixir and Loa. Because she was Ed Brubaker and Matt Fraction's pick, Pixie ended up not only on the ''Uncanny X-Men'', but with her own miniseries.
** Doop was a fan-favorite in ''X-Force'' and ''X-Statix'', and his return in ''Wolverine and the X-Men'' was much-appreciated.
** Dr. Nemesis is a minor one due to being a hilarious, CrazyAwesome mad scientist.
** Of all the characters introduced in Grant Morrison's run, Fantomex was definitely the most popular. He's managed to last while most of the characters from Morrison's run were largely forgotten about, changing from a minor new guy into a series regular.
** For being a Chuck Austen character, Mammomax the Elephant Man is surprisingly well-remembered by the fandom, probably due to his inherent NarmCharm.
* EthnicScrappy: Creator/GrantMorrison during his tenure writing created Angel Salvadore, as some sort of vaguely Latina, foul-mouthed 14 year-old who was kicked out of her house by her step-father when her mutant powers developed. Some UnfortunateImplications come into play when Angel later is impregnated (by Beak, the chicken-man during a field trip with Xorneto) and suddenly lays ''half-a-dozen mutant children'' in large eggs. Though justified by the fact that her mutant powers make her very fly-like, and her name is doubly ironic because of how unpleasant she can be and X-Men already have the more experienced Archangel.
** Thunderbird plays with this. Many fans wonder what it would be like [[WhatCouldHaveBeen if he had not died]], but he clearly would've fallen into this trope.
*** Well, he'd probably be a lot like his BackupTwin, Warpath.
* FamilyUnfriendlyAesop: Frequently, Rogue gets forced into keeping her powers despite how mind-numbingly horrible they are.
** Run-ins with TheNineties Black King, Shinobi Shaw, tended to lean in this direction to UnfortunateImplications levels. Like many 90s villains, Shinobi had a giant FreudianExcuse in being abused in his childhood by his father, Sebastian, and as an adult compensated for his hollow interpersonal life by being a DepravedBisexual. On at least three separate occasions the heroes tear Shinobi apart verbally, not for being a ''villain'', but for being effeminate and weak. Flash-forward twenty years and it's really hard not to side-eye the writers of those stories.
* {{Fanon}}: Many fans prefer to consider Creator/ChrisClaremont's original plan for the identity of Nightcrawler's parents--that Mystique used her powers to temporarily become male and impregnate her lover Destiny--to be official {{canon}}, largely because Chuck Austen's decision to make Azazel his father (thus making Nightcrawler half-demon) was met with such lukewarm reception.
* FandomRivalry: In recent years, one has cropped up between X-Men fans and Avengers fans, largely due to factors like the movie rights red tape and the recent crossovers that put the two against each other for rather weak reasons. While generally most fans have acknowledged that the writing of these crossovers is bad, there's some debate about whether one side is treated fairly or not.
** HypocriticalFandom: And, as a result, there's been a lot of hypocritical claims from both sides too. X-Men fans have been in uproar over Marvel's apparent favourtism towards the Avengers due to Marvel Studios owning and producing the film rights of the Avengers, but a lot of the 'evidence' of this apparent conspiracy to undermine the Fox-produced X-Men films is either questionable at best or outright fabrication at worst, or even things the X-Men fandom enjoy themselves now such as multiple books about their sub-teams, solo-books for their characters, and publicity towards their regular events. Conversely, a lot of the criticisms thrown at the X-Men (being too dark, exaggerated depiction of incompetent or abusive government and law enforcement figures, frequently recruiting former villains, LoadsAndLoadsOfCharacters, preachy anvilicious messages, etc) are largely criticisms that equally fit the Avengers too, as well as other big superhero teams like DC's ''Franchise/{{Justice League|of America}}'' and TeenTitans. In general, the only thing that Marvel are doing for one that they're not doing for the other is producing a current animated show for X-Men, which is something they've done repeatedly in the past for the X-Men and only recently started doing for the Avengers (X-Men have had [[WesternAnimation/XMen three]] [[WesternAnimation/XMenEvolution animated]] [[WesternAnimation/WolverineAndTheXMen shows]] and an [[Anime/XMen anime]], while the Avengers have [[WesternAnimation/TheAvengersUnitedTheyStand now]] [[WesternAnimation/TheAvengersEarthsMightiestHeroes had]] [[WesternAnimation/AvengersAssemble the]] [[Anime/MarvelDiskWarsTheAvengers same]]).
* FanonDiscontinuity: A lot of stuff is contested by fans but if there's one thing fans can agree on, it's Chuck Austen's entire run.
* FanPreferredCouple: In terms of sheer fan works, there's no more popular of a couple than Gambit and Rogue, but they currently are together. There's a fairly large, vocal fanbase for current couple Magneto and Rogue.
* FashionVictimVillain: '''[[http://www.uncannyxmen.net/db/spotlight/showquestion.asp?faq=12&fldAuto=154 Changeling.]]''' Presumably the reason he's remained dead for so long is so no one will have to see that horrible headwear ever again.
** A close second is Mesmero, who... well, just [[http://vignette4.wikia.nocookie.net/marveldatabase/images/9/93/Mesmero_(Vincent)_(Earth-616).png look at him]].
* FountainOfMemes: [[WebVideo/MyWayEntertainment "Pimp smack yo' ass, bitch!", "Comb yo' beard, I don't wanna hear that shit", "You can't run from the Juggernaut."]]
* GeniusBonus: The word "sinister" comes from the Latin word for "left". When Sinister first appears (as a shadowy figure in Sabertooth's memories) he has his left hand upraised.
* HilariousInHindsight: 1968 saw issue #48 and an encounter with Computo, an artificial intelligence that could create his own cybernetic mooks. They were called Cybertrons -- a term put to more extensive use in [[Franchise/{{Transformers}} a different franchise]], one that included a Marvel comic.
** In the 1960s, several stories had Scott Summers reject offers by Magneto to join the Brotherhood of Evil Mutants citing his preference for Xavier's coexistence beliefs and even foiled a plot by Magneto to create a new generation of artificially made mutants. Present day, Cyclops is now, constantly, being compared to Magneto due to his more extreme methods of protecting mutants.
** The original X-Men stories in the 1960s featured a pretty clear power ranking for the team members by continually referring to individual members as "the strongest X-Man", "the weakest member", "the second weakest member" and so on. The members seemed to be ranked as such (from strongest to weakest): Cyclops, Beast, Angel, Iceman, Marvel Girl (Jean Grey). Fast forward to modern day: guess which two members of the original team are now [[PersonOfMassDestruction Omega-level mutants?]]
* HoYay: Between Colossus and Wolverine. Ultimate Colossus is a StraightGay with an unrequited crush on Wolverine. In mainstream, they're just HeterosexualLifePartners.
** Between Wolverine and Nightcrawler, who are also very close. Whenever someone targets Wolvie's loved ones, Kurt is included.
* JerkassWoobie: Wolverine and Magneto are two of the most famous examples in the Marvel Universe. Wolverine is more Woobie than Jerkass but Magneto fits ''perfectly''.
* JerkSue: In the hands of some writers, Kitty Pryde, Cyclops, Emma Frost, and Wolverine. Logan especially, considering that he's been used for JerkassHasAPoint moments too many times that whenever he criticizes anyone for their behavior, he's almost undoubtedly done the exact thing he's condemning. At this point, being a giant hypocrite is slowly becoming a character trait for Logan.
** What makes Wolverine such a [[LoveItOrHateIt frustrating]] example of this trope is that the character is basically a KarmaHoudini on wheels -- other Marvel U AntiHero characters like ComicBook/ThePunisher, [[ComicBook/{{Venom}} Agent Venom]], and in the X-Universe SelfDemonstrating/{{Magneto}} and most pointedly ComicBook/{{Cyclops}}, '''all''' suffer the consequences of their JerkAss behavior through generous doses of ZeroPercentApprovalRating, CantGetAwayWithNuthin, etc. Logan is a character with a body count behind him that would make most SerialKiller characters blush yet enjoys a consistent HundredPercentAdorationRating and is regarded as a trusted ally of characters like Captain America, Spider-Man, etc... you know, the same people who would be calling for him to stand trial [[ProtagonistCenteredMorality if he were anyone else]]. In general, both the character ''[[RunningTheAsylum and the narrative]]'' bend over backwards to handwave Wolverine's crimes. At one point Logan even [[MoralMyopia says himself]] that he's only ever killed people who deserved it; as his victims mostly consist of various {{Mooks}} and RedShirts, the narrative treats this as him telling it like it is rather than the WhatTheHellHero moment it ought to be.
* LesYay: Anything by Creator/ChrisClaremont. Try to deny the subtext between Storm and Yukio, Mirage and Wolfsbane, or Selene with Rachel Summers and Magma.
** Of course, he did it with [[HoYay guys]] and [[FoeYay villains]], too...
* MagnificentBastard: Sebastian Shaw; a would-be usurper comments at one point that trying to outplan him is likely a more difficult task than conquering a country.
** Cyclops during the Utopia period of X-Men history. Not everyone can con an entire army of vampires, but Cyke sure can.
** Magneto has his moments, too.
** Your mileage will ''really'' vary on this one, but Mr. Sinister.
** Chris Claremont can be considered an out-of-character example for all the crap he managed to sneak past his editors, with sneaking in the Mystique/Destiny relationship being his CrowningMomentOfAwesome.
* MemeticMolester: FABIAN CORTEZ. The dude is basically the X-King of bad touch.
* MemeticMutation: Thanks to Comic Book Resources, Beast [[InferredHolocaust is a war criminal]], Iceman [[AmbiguouslyGay is gay]], and Wolverine is Rachel Summers' real father.
** A relatively complete list of the CBR X-Boards' inside jokes can be found [[http://forums.comicbookresources.com/showthread.php?t=356992 here.]]
*** Amusingly, that old CBR joke about Iceman being AmbiguouslyGay eventually became AscendedFanon in ''Uncanny X-Men'' #600.
** ''Days of Future Past'' may just have the most [[http://darkwingblog.files.wordpress.com/2011/04/darkwingduck_12_cvb_1.jpg?w=400&h=600 frequently]] [[http://www.liveforfilms.com/wp-content/uploads/2011/01/doctor-who-days-of-future-past-452x700.jpg parodied]] [[http://fc05.deviantart.com/fs14/f/2007/047/e/6/Star_Wars_Insider_Cover_by_robcamp1000.jpg cover]] [[http://images.wikia.com/memoryalpha/en/images/3/3b/The_Last_Generation_issue_1_variant_cover.jpg of all]] [[http://static.comicvine.com/uploads/original/9/96524/2591536-GitPX.jpg time.]]
** Mr. Sinister's Ultimate counterpart infamously introduced Ultimate Professor X to the latter's "true enemy": [[http://desmond.imageshack.us/Himg205/scaled.php?server=205&filename=stairs29bc.jpg&res=landing Stairs.]]
** "To me, my X-Men!" It's since been used by Cyclops, as well as [[spoiler:an older]] Franklin Richards in ''FF'' as "To me, [[spoiler:my Galactus]]." Kitty's now using it, too.
** Magneto/Cyclops was right! [[note]]The rally cry behind Magneto and later Cyclops' WellIntentionedExtremist actions.[[/note]]
* {{Misblamed}}: The weird way [[StrangledByTheRedString Cyclops and Emma Frost were hooked up]] and Jean Grey dying were never Grant Morrison't intention. He had something entirely different planned out but [[ExecutiveMeddling an editorial proclamation forced him to change it at the last minute]].
* MoralEventHorizon: Ultimate Wolverine's attempted murder of Scott Summers.
** Wither, whose purpose seems to be to explore how a villain becomes a villain, probably crossed this with his recent double-murder.
*** Mystique crossed it in ''Dream's End'' (murdered Moira [=McTaggart=] and stabbed Rogue), then double downed after Xavier and Rogue forgave her during ''Blinded by the Light'' and ''Messiah Complex''.
*** Bishop killed innocent government soldiers, destroyed the X-Mansion, and tried to kill a baby. When Cable saved the kid, Bishop shot at Cable and mortally wounded Xavier instead; then stole a time machine and did even worse to try and kill Cable and the kid until he wiped out all life on Earth.
*** Magneto killing Jean Grey. Later retconned. He still has ripping out Logan's skeleton though and his general mistreatment of his kids.
*** Cassandra Nova sending the Sentinels to destroy Genosha.
*** Fabian Cortez drags his motley band of harried refugees onto Magneto's space rock doorstep, promptly pulls him out of his HeelFaceTurn and back into villainy, and then sets up a scheme to get rid of both the X-Men and Magneto himself all at once, leaving him free to claim the role of mutantkind's leader. The fact that this scheme will result in the death of his ''own sister'' doesn't bother him in the slightest, and he doesn't even spare a word for poor Anne-Marie as he flies away gloating. He'd do plenty of horrible stuff later too, but it was just gilding the lily: right here in his ''first story'' was when the dude crossed the Event Horizon, and he never once looked back.
*** It's hard to tell just WHERE Sabretooth crossed it, but his most heinous act involved taking in Daken and playing the role of the father that Daken (who has MAJOR daddy issues, to put it mildly) never had, all the while slowly grooming him for a confrontation with his father, resulting in his death at Wolverine's hands. Why did Sabretooth do this? Simple. He just wanted to hurt Logan at a far deeper level than he could ever manage on his own.
** Vulcan crossed it when he killed [[spoiler:his own father, Corsair]].
* MyRealDaddy: Despite being created and originally produced by Creator/StanLee and Creator/JackKirby, the series suffered from low sales and never truly found its voice until Creator/ChrisClaremont and Dave Cockrum (and soon after, Creator/JohnByrne) took over in the 1970s.
** Louis Simonson gets some credit, for writing definitive versions of Archangel. Grant Morrison for Emma Frost, though that one is a case of this being used in a ''bad'' way. There's a reason this is YMMV.
* {{Narm}}: During one of Claremont's early issues, Storm defeats a Sentinel, then momentarily angsts over the fact. Why? Because it screamed as she destroyed it. Never mind that it was just trying to kill her and the other X-Men, destroying a killer robot is bad enough to make Storm have a MyGodWhatHaveIDone moment.
* NarmCharm: The existence of Master Mold, a giant Sentinel who spawns 'smaller' Sentinels from his tummy. Yes, he has the power of robot pregnancy.
** There's also Sauron, one of the X-Men's oldest villains and definitely their campiest. He's like a walking example of why people read comics -- deep and complex stories are fine, but sometimes you just want to check your brain at the door and read about people in silly costumes being menaced by a hypnotic vampiric were-pterodactyl dinosaur man.
* NeverLiveItDown: Jean doesn't actually come BackFromTheDead that much. It only truly happened once (other times were fakeouts or resurrecting instantly, which applies to half the other characters as well). She was known for lots of crazy things happening to her, but it got recently morphed into solely coming back from the dead, when that isn't true. Probably people seeing the word "Phoenix", and not bothering to actually do research.
** Scott Summers had his squeaky clean image tarnished forever by his shabby treatment of Madelyne Pryor, abandoning her and their son Nathan. A tarnished image that was then irreversibly destroyed when Scott cheated on Jean Grey with Emma Frost. And now, everything that happened during ''[=AvX=]''. What is most interesting is that Scott didn't really abandon Madelyne, he simply went to see for himself if Jean had come back to life and got involved with X-Factor, during which time he kept in contact. By the time he came back to them they were gone. AND also the fact that while Jean made out with Logan and even Angel multiple times during the course of her relationship with Cyclops, she's never called out on it, despite the fact she would gossip with Storm about it. Cyclops gets taken advantage of by Emma Frost (since he was very unstable at this point) by her forcing him into having a TELEPATHIC affair, yet Cyclops is still treated like a scumbag. Adding to that, Jean threw herself at Wolverine during this time and also the fact that after Jean died, Cyclops wanted to go off on his own and instead was psychically FORCED by Jean into starting a relationship with Emma, who was pretty much Scott's mental rapist, because if they didn't end up together, it would lead to a horrible future. Yet somehow everything is his fault and he's a jerk... double standard anyone?
** Gambit, while he was always an AntiHero, actually only betrayed the X-Men once, when he decided to go and join Apocalypse thinking [[IdiotBall that it could help mutants]] and that he could retain his personality after becoming a Horseman. [[TheDarkSideWillMakeYouForget He was wrong.]] When he [[HesBack returned to normal]], he returned to the good side as well. Yet people seem to think that he betrayed everyone and their mother more times than you can count.
*** He also covered up his involvement in the massacre of the Morlocks; he was tricked into that and had no idea it would happen, but it's easy to see why he wouldn't exactly be trusted.
** It might be surprising to a lot of people only familiar with the adaptations that Magneto hasn't actually been a villain in over a decade, unless you count his turn in Morrison's run, in which he was either a victim of DemonicPossession, an impostor, or both, depending on which {{retcon}} you believe.
** Nightcrawler's faith. It was never intended as a major aspect of his character, in fact most of the time he wasn't even all that religious, but in the hands of some less-than-talented writers [[labelnote:*]](*cough*Chuck Austen*cough*)[[/labelnote]], it's like he exists to be the token Christian, only for a change of writers to result in this being ignored or downplayed again. Similarly, Northstar's sexuality. Him being gay, other than making him one of the most well known gay superheroes, isn't really that big of a deal to his character at large. His [[{{Jerkass}} personality]] doesn't hinder on the fact he's gay. Yet, in the hands of some people[[labelnote:*]](*cough*Chuck Austin*cough*)[[/labelnote]], its like all that matters is that he's gay.
** Emma Frost(rightfully) gets a buttload of this due to the fact that she manipulated and essentially ''[[DoubleStandardRapeFemaleOnMale ra]][[DoubleStandardRapeSciFi ped]]'' Scott and [[KarmaHoudini got away with it]] by starting a relationship with him after Jean's death. The fact that she is his ''therapist'' just made her into more of a colossal bitch. This is somewhat in-universe at well: Rachel Summers never forgave her for having an affair with Scott, although thankfully she never learns of the whole story. Their relationship was mercifully terminated during the Avengers vs X-men events, although Scott never calls her out on her actions.
* NightmareFuel / NauseaFuel: [[http://img3.wikia.nocookie.net/__cb20101201003936/marveldatabase/images/7/7e/Ichisumi_%28Earth-616%29.jpg Ichisumi]] [[http://marvel.wikia.com/Ichisumi_%28Earth-616%29 the Pestilence]], a.k.a. one of Apocalypse's Horsemen. Her mutant power is to release an infestation of near omnivorous yume beetles stored within her own body by dislodging her jaw, spawning from her mouth in massive swarms either devouring or disfiguring her intended mark. She is also able to mentally link with them when they return to her as each and every individual being her colony consumes also imparts unto them; and subsequently upon their habitat/queen, much of the victims memories. You think the power to control insects like ''ComicBook/AntMan''[='s=] power is lame? Think again!
** Mountjoy is a rarely-seen mutant criminal from the future with a truly ''horrific'' power that combines TheAssimilator with pure unleaded BodyHorror. He can absorb other beings into himself, a process he refers to as a 'merger', and if he doesn't 'divest' the victim they are eventually digested, with Mountjoy gaining all their abilities. At one point he absorbs a normal woman, and as he proceeds to monologue to himself the woman's ''screaming face rises out of his head'', followed by her arms briefly flailing from under his coat. He doesn't even ''pause'' in his monologuing, suggesting that this sort of BodyHorror is just par for the course, and when the woman's face rises up again he just gives his forehead a little smack and smirks to himself while remarking that he "loves it when they struggle".
* PanderingToTheBase: For whatever reason, the half of X-Men fandom's BrokenBase that favors Wolverine finds themselves buttered up a lot more than the side that wants him to go away. Any issue with a lineup of X-Men will usually feature Wolverine will be front and center. There was even a cartoon series called ''WesternAnimation/WolverineAndTheXMen'', [[SpotlightStealingTitle where the X-Men got second billing]]. The first three ''Film/XMen'' films (especially the third one) are arguably more like Wolverine films than X-Men films.
** Another card-related case was the tie-in Top Trumps-like card game for the third film. Each card had four traits, Speed, Strength, Fighting Ability, and Intelligence, each ranking one to seven. Most characters had about two for two of the traits, a four for one more, and six or seven (e.g., Angel had lower traits for the latter three, but a six in speed, while Mystique had low for all but fighting skills and intelligence, and Colossus excelled at strength). Logan had six or seven for ''every trait''. He's apparently a better fighter than Mystique (which as the first ''X-Men'' movie showed was [[CurbStompBattle not the case]]), faster than Angel, stronger than Colossus, and smarter than Doctor Doom.
* RescuedFromTheScrappyHeap: Ironically, Wolverine was widely hated when he first debuted, so much that the creative team seriously considered killing him off. (He was spared in favor of Thunderbird since a HealingFactor and WolverineClaws powerset was very unique at the time.) After some character expansion and a SugarWiki/MomentOfAwesome, Wolverine became so popular that he's now the face of the X-Men. Though he's become a BaseBreaker since then, partly because his popularity got taken a bit too far.
** Madelyne Pryor sort-of is an example of this. Back in 1989, Marvel intentionally wanted readers to hate Pryor to make it easy [[DieForOurShip to kill her off]] and RetGone her into an UnPerson, and it all worked for several years. Meta circumstances have since turned that around somewhat. The Information Age (such as websites, like ''this very one''), and also that Marvel just can't stop from repeatedly reprinting trade-paperbacks and the like which include all of Pryor's pre-1989 appearances, both undercut Marvel's party line. And now over the years, Marvel's handling of Jean Grey and Cyclops constantly angers fans. So lately the hatedom towards Pryor seems mostly silent, while her advocates/apologists seem pretty vocal.
** Prior to ''Film/XMenFirstClass'', Azazel was one of the most unpopular of all the X-Men villains. Now, he's... well, ''still'' unpopular, at least in his original incarnation, but his adaptation has fared rather a bit better in reception.
* RomanticPlotTumour: The Wolverine/Jean/Cyclops love triangle. While fans tend [[OfficialCouple to ship any]] [[FanPreferredCouple combination of]] [[HoYay the three]], many dislike the way that the triangle essentially just makes Wolverine and Cyclops act like dicks to each other while Jean condescends them for fighting while actively fueling said fighting. Even worse given the fact that, despite Jean being ''dead'', the two boys are ''still'' fighting over her.
* RootingForTheEmpire: A not-insignificant portion of the fandom reads ''entirely'' for the bad guys, even knowing StatusQuoIsGod in this medium. The fact that the X-Men seem to suffer from perpetual GenreBlindness, trucking on with their doomed mission despite very obviously living in a CrapsackWorld, makes it hard for some not to root for the more VisionaryVillain antagonists like Magneto, Exodus or, in recent years, Cyclops. The general idea here is "they might bad guys, but at least their hands aren't permanently attached to the IdiotBall."
* SacredCow: Creator/ChrisClaremont himself is this on various forums (like Comic Book Resources), where so much as saying that Claremont isn't all he's cracked up to be, or that he's past his prime, or anything of the sort can be akin to facing an angry mob. This mainly comes up in regards to his original 16+year ''X-Men'' run, but you can still get similar responses to just about anything the man's wrote. (Or theoretically ''could'' write, such as an ''Avengers'' run, for example...) In particular, saying Claremont's handling of women was anything other than perfect can get you tarred and feathered in the right circles.
* TheScrappy: Very few people seem to like Ink. Even fewer like the new Hellfire Club made up of 12-year-olds. Then there's Maggot, though most prefer to forget about him.
** Any mutant willing to work with the government can get this, too, the most prominent in recent years being Wolverine and Havok. In the characters' defense, this is less about them and more due to the fact that the government's position on mutants varies from morally-ambiguous but fair to FinalSolution-crazy dictatorship DependingOnTheWriter.
** Quentin Quire started off as a minor character, basically the super-powered mutant equivalent of a school shooter and a teenaged sociopath who manipulated others into joining a small cult of wannabe Magnetos, before dying of a drug overdose of sorts. He was revived a few times, before finally returning during ''Schism'', serving as one source of the conflict between Wolverine and Cyclops to push them apart further, before joining Wolverine's school. He's continued to be written by Jason Aaron, who's since then made him one of the main characters, including being the main student, of his run, with him being at the front of every big event he writes, including his future self being the Phoenix in ''Comicbook/BattleOfTheAtom''. All of this, despite being largely loathed by fandom. Every writer tends to have one kid they push, and usually it works. This case, however, it most certainly has not, and isn't helped by his continued use.
** Flip-flopped with Madelyne Pryor, who seemed to have been the most [[{{Hatedom}} vehemently hated]] of all characters among X-Men fandom for many years [[ComicBook/{{Inferno}} since 1989]]. Then, after Cyclops and Jean Grey were "broken up", Grey got "pink slipped", and Emma Frost was "hooked up", the hatedom towards Pryor seemed to abruptly wither and then die with a whimper.
** Azazel was this for a real long time, being featured in the infamous "The Draco" story which is widely considered to be one of the worst X-Men stories of all time. It took being adapted into ''Film/XMenFirstClass'' in an almost completely-reimagined form for him to get some semblance of RescuedFromTheScrappyHeap.
** Matthew Malloy, a recent GenericDoomsdayVillain created by... uh, let's go with [[BrokenBase polarizing]] writer Creator/BrianBendis.
** Also the Apocalypse Twins, a pair of evil mutants introduced in ''Uncanny X-Force'' who look like dollar-bin refugees from ''VideoGame/GuiltyGear'' and narratively speaking, are the unholy fusion of [[WalkingWasteland Holocaust]] and [[ThoseWackyNazis the Fenris Twins]].
* ShipToShipCombat: Fandom is divided into those who think Rogue ''must'' be with Gambit and those who think that no matter who they themselves favor, ''anyone'' is preferable to Remy as Rogue's love interest.
** Interestingly, Remy/Rogue wasn't even the original endgame. Chris Claremont created Gambit as STORM'S love interest and planned on having a shock reveal where Storm would ultimately find out that Gambit was really arch-villain Mr. Sinister, in a new body designed to further torment the X-Men.
*** Take that and toss in Scott/Jean/Wolverine and Scott/Jean/Emma Frost; the former (Jean and Wolverine hooking up) was teased at the start of the Casey/Morrison run but fans were so overwhelmingly negative that Morrison ended up going with Emma/Scott, which did not go over well and led to later writers going with Cyclops/Emma Frost/Namor, as far as retconning a relationship with Namor into Emma's past to pander to fans who HATE the Scott/Emma pairing.
* StrangledByTheRedString:
** Some fans think this way about Scott dating Emma Frost. Some even like to believe that Creator/JoeQuesada (well-known for his dislike of characters being married) forced Creator/GrantMorrison to [[DroppedABridgeOnHim drop a bridge on Jean Grey]], because they don't want to believe that Morrison came up with something like this on his own. (As a matter of fact, no X-Men writer ever had a freer hand what to do with them.) What's really bad is the excuse given for why they're dating so soon after that is "not" a rebound relationship (Morrison had them have an adulterous psychic affair before Jean's death, but realistically that was Emma -- his supposed therapist -- unethically taking advantage of him when he was vulnerable.) As proof it was contrived, there is this BadFuture that Jean needed to avert. Going back in time, like ''every other'' such future, somehow wasn't an option. Instead the only options were: 1. Scott and Emma didn't get together, the X-Men would fall apart and things go all to holy hell. 2. Jean brainwashes her husband into forgetting his feelings for Jean and giving in to his attraction to Emma.
** ''Most'' fans regard ComicBook/BlackPanther and ComicBook/{{Storm}}'s marriage as something akin to this. Many of those who were interested in the idea were annoyed at Reginald Hudlin's [[ProtectionFromEditors hamfisted railroading]] of the relationship from casual acquaintance to "Wedding of Perfect Couple" as soon as possible, especially since they were made out as some kind of "First Couple of Black Superheroes." Subsequent writers were not subtle about their distaste for the pairing, and found any possible reason to have Storm go on missions with the X-Men or for T'Challa to have solo adventures. After the events of the ''X-Men vs. Avengers'', where the two fought, their marriage has been annulled.
** Bobby Drake/Iceman and Kitty Pryde/Shadowcat seem to be falling into this trope. As of the seventh issue of the ''Wolverine and the X-Men'' comic, Bobby and Kitty have shared two kisses, despite the fact that they've spent years as distant acquaintances at best. They had a decent relationship arc in the ComicBook/UltimateMarvel universe, and writers have been known to mix the two up before. It comes completely out of nowhere in the main Franchise/MarvelUniverse.
** Magneto/Rogue has always been one of the weirder X-relationships. It's pushed every couple of years by the Powers That Be, despite fandom largely being either irrelevant to or repulsed by it, and it was canon in the ''ComicBook/AgeOfApocalypse''. Recent years have seen it cross into UnfortunateImplications territory as Magneto's appearance has grown steadily older while Rogue's has grown (for some reason) steadily younger.
* StrawmanHasAPoint: Very often it seems like is [[MemeticMutation Magneto was right]] arguing that peaceful co-existence between humans and mutants is impossible, considering that no matter what the X-Men do, the plot never seems to get any closer to reaching that, particularly because people in the Marvel Universe are TooDumbToLive and suffer from AesopAmnesia regarding that theme. It gets even worse that in a lot stories throughout the Marvel Universe, especially in recent years, they seem willing to easily sacrifice any and all of their freedoms at a moment's notice, so quite often it would seem like the world would be better if the X-Men let Magneto TakeOverTheWorld, since at least he doesn't go making the [[ComicBook/NormanOsborn Green Goblin]] the most powerful man in America.
** Robert Kelly's arguments (such as comparing mutant registration to gun control) actually made sense to some readers and viewers. Then they turned an otherwise logical argument into an {{anvilicious}} allegory to [=McCarthyism=] when they had the senator hold up a "list of names of identified mutants", shifting the argument from "Some mutants are dangerous" to "All mutants are dangerous." Of course, once the killer mutant-seeking robots come in (and ''they always do''), it seems clear that Kelly is JumpingOffTheSlipperySlope, even if his arguments do have a grain of truth to them.
* TheyWastedAPerfectlyGoodPlot: The recent 'Last Will and Testament of Charles Xavier' story featured a brief, throwaway appearance by Exodus as an agent of SHIELD and the head of its psi division. Yes, ''[[KnightTemplar Exodus]]''. And the thing is, exploring how a character like Exodus would [[HeelFaceTurn come to work for SHIELD at all]], let alone go so far as to help an organization primarily made up of humans hunt down a dangerous mutant threat, would be a story seriously worth reading. Unfortunately, though, Bennet was just there to [[TheWorfEffect get worfed]] by Bendis's GenericDoomsdayVillain Matthew Malloy and he played no further part in the rest of the story, which was so bad that it ended up being retconned.
** UsefulNotes/TheNineties are pretty much a ''landfill'' of these, thanks to the high creator turnover and endless backstage politics going on at the time. A lot of villains from the era (indeed, entire villain ''teams'' fall under this umbrella) had massive potential but thanks to poor writing are barely remembered today (The Acolytes, the Upstarts, the Externals, etc). There's also the characters that never even got a ''chance'' to show their stuff, like Adrienne Frost, Genesis and Haven. If you ever wondering why the segment of the fandom that's Nineties-centric just tunes out of the current Cyclops VS Wolverine rigmarole altogether, well, this is why. It's possible that even Marvel editorial's finally recognized it, as they recently announced a new ''1992 X-Men'' series that might just breathe new life until all these forgotten plots and give these unappreciated characters their due.
* VindicatedByHistory: The original series was never a top-seller, but sales had declined so much by the end of the 1960s that the book was cancelled. A little bit later, the series (with its original numbering) returned, but only as a reprint title. A number at Marvel did like the book and the characters, but they couldn't figure out ''how'' to bring them back until 1975s ''Giant-Sized X-Men #1''. After that was published and received strong response, Marvel has kept the X-Men in regular publication ever since -- adding many spin-offs and mini-series to the archive (and many hours of outside, successful media).
* TheWoobie: The Morlocks after having been massacred by the Marauders.

[[folder:[=YMMVs=] for the 1992 X-Men animated series:]]
* AcceptableTargets: Graydon Creed and the Friends of Humanity.
* AwesomeEgo: Apocalypse has a massive god complex, views all life as beneath him, that only his vision of reality has an right to exist and scoffs and at morality outside of his own, and looks awesome doing all of it.
* SugarWiki/AwesomeMusic: [[http://www.youtube.com/watch?v=7IzSGvXc_PM The show's opening theme.]] Undisputably {{Badass}}.

** Colossus' theme music.
* BadassDecay: ComicBook/JeanGrey in the comics is one of the most powerful X-Men characters. By contrast, she suffers a ''heavy'' case of AdaptationalWimp in the show, with her telepathy usually backfiring on her or her telekinesis not holding up well under strain. It was likely that this nerfing was intentional, as she would otherwise be at StoryBreakerPower levels (tellingly, the villain Exodus, himself a frequent wielder of StoryBreakerPower, was one of the few characters who never made an appearance in the show). The Season 3 adaptation of the Dark Phoenix Saga is the only time Jean comes anywhere close to her comic book level of power.
* BaseBreaker: Jubilee is either hated by fans that find her increasingly annoying and her powers to be stupid, or loved by fans that enjoy her spunkiness as well as her playful and innocent attitude. It's a similar case for her in the comic books as well. Some also dislike her for not being ComicBook/KittyPryde, as Jubilee pretty much replaced Kitty in the comics as "Wolverine's sidekick."
* BizarroEpisode: Mojovision. Holy crap, Mojovision.
* CompleteMonster:
** ComicBook/{{Apocalypse}} is a would-be mutant conqueror who despises everything that isn't him and [[AGodAmI fancies himself a God.]] In his first appearance he builds a machine designed to take away people's free will and make them his slaves. He tricks four self-loathing mutants, including Warren "Angel" Worthington, into believing this machine will cure them of being mutants, preying on their feelings of inadequacy to subject to them to a painful process of transformation them into his [[CoDragons Four Horsemen of the Apocalypse]]. [[NamesToRunAwayFrom Apocalypse]] then orders his Horsemen to go on a rampage across the globe. Rogue was able to free Angel from Apocalypse's control with her Power Absorption abilities, but Angel was a mentally unstable wreck after that experience. In his next appearance, Apocalypse creates a plague designed to wipe out most humans and mutants. This plague furthers tensions between humans and mutants, with some humans blaming mutants for it and creates a BadFuture, where several mutants are dying from this plague. Later Apocalypse manages to get hold of some time travel technology and uses it to travel to the Axis of Time, a interdenominational area that controls time itself and plans on [[OmnicidalManiac destroying the time stream and reality itself, so that he can recreate it in his own image]].
** [[VillainWithGoodPublicity Graydon Creed]] is the leader of the anti-Mutant group, the Friends of Humanity. Under Creed's orders, the Friends of Humanity attack half-way houses and other businesses and non profit organizations that are sympathetic to mutants. Creed even organizes an attack on a hospital for the blind, because the gentle, intelligent mutant Hank "Beast" [=McCoy=] works there to treat to blind patients. Creed later admits he plans to commit genocide against mutants amongst his most loyal followers. It is revealed Creed is actually [[BoomerangBigot the son of Mystique and Sabretooth, two prominent mutants.]] After the Friends of Humanity find out that Creed has mutant parents and siblings, he is kicked out of the group, breaking down at an image of Sabretooth and screaming '''I'm not one of you! I'm normal! You are not my father!''' In order to get back into the Friends of Humanity's good graces, Creed devises a plan to murder his mother and his mutant siblings, viciously rejecting he has any connection to them while trying to murder them. [[SaveTheVillain Even the X-Men saving his life as opposed to leave him to die]] after he's double-crossed by Apocalypse [[UngratefulBastard does nothing to change his view]].
** ComicBook/{{Sabretooth}} ([[AdaptationNameChange renamed Graydon Creed, Sr.]]) is a cruel PsychoForHire and BloodKnight with a obsessive hatred of Wolverine. Magneto uses Sabretooth to infiltrate Xavier's school where Sabretooth is injured after a confrontation with the police while he is pretending to be protesting at Beast's trial. The X-Men rescue Sabretooth and nurse him back to health and Xavier even attempts to help Sabretooth deal with his inner demons. Sabretooth repays this kindness with spite and cruelty as soon as he is able, tricking the young mutant Jubilee into loosening his restraints and then attempting to murder her. After being driven away by the X-Men, Sabretooth later returns when Wolverine is in Northern Canada, having left the X-Men due to his conflicted feelings over Jean Grey. Wolverine later befriends the population of a small Inuit Village, who help him discover feelings of inner peace. Sabretooth kidnaps several members of Inuit Village while Wolverine is out fishing and straps bombs to them in order to draw Wolverine out and force him to fight. It is later shown in flashbacks that Wolverine and Sabretooth were partners in special forces. Sabretooth abandoned their entire unit to die against the monstrous cyborg Omega Red and scoffs "So what?" when Wolverine confronts him over this. After Graydon Creed uses up his final chance with the Friends of Humanity, they parachute him out of a plane to Sabretooth's cabin. The last we ever seen of Graydon Creed is screaming in terror, lifted up by his father with Sabretooth looking murderously thrilled at getting his claws on his son at last.
* ContinuityLockOut: The first two seasons are pretty heavy on story arcs. The first season even sees most episodes leading directly into the next, meaning you'd have no choice but to watch the premiere and the episodes in their proper order. Season 3 was a bit better in this regard--having more stand-alone adventures, but also a major story arc and prominent sequel episodes. With few exceptions, Seasons 4 and 5 were generally more episodic.
* CriticalResearchFailure: In one episode, Gambit travels to Washington, D.C., which apparently is located in the state of Washington.
** At points it becomes obvious this show was produced pre-Internet, such as the episode that takes place in Tanzania, only the writers had no idea what African country Mt. Kilimanjaro is in so it is only referred to as "... that part of Africa."
* EnsembleDarkhorse:
** Beast. [[WordOfGod Eric Lewald]] states that the writers considered him a guest character in Season 1, which is why he was largely sidelined. Fans and writers alike took to the character, leading to his increased prominence for the remainder of the series.
** Morph was in the first episodes ''entirely'' for the purpose [[RedShirt of being killed off]] so the writers could show how serious the series would be. However, his unexpected popularity led to him being revived in the second season.
** Nightcrawler's episode was so well-received they wrote a second one just to bring him back and the writers seriously considered [[SixthRanger having him join the X-Men]] after "Bloodlines."
*** Which would have been quite appropriate, seeing as how Nightcrawler was part of the original ''New X-Men'' lineup from the 70s -- alongside Wolverine and Colossus.
* EscapistCharacter: Jubilee is a hybrid of this and AudienceSurrogate for the show's target demographic, being introduced in the first episode as a young new mutant who is quickly adopted into the X-Men.
* EvilIsSexy: Mystique, so very much.
* FanPreferredCouple: Storm/Wolverine after "One Man's Worth."
* FoeYay: In the final episode of the series, [[spoiler:Magneto, upon hearing that he may be the only one able to save the dying Xavier, abandons the army he had gathered and goes to save his arch-enemy.]] It is possible that they're just ''really good friends,'' [[AlternativeCharacterInterpretation but...]]
--> '''Jean Grey:''' "How much do you '''love''' Charles Xavier?"
** The number of these moments between Magneto and Xavier is somewhat HilariousInHindsight seeing as several years on, openly gay actor Creator/IanMcKellen was cast as Magneto in the live-action films.
** James [=McAvoy=] and Michael Fassbender took the HoYay and FoeYay to ''ridiculous'' levels in ''Film/XMenFirstClass''.
* FridgeLogic:
** The Sentinels, which are government made and run, wind up being a much greater threat to the public then mutants even if they worked as intended.
** For the viewers who aren't familiar with comics, the public respect towards Superheroes (both ComicBook/TheAvengers and ComicBook/MsMarvel) can be this trope in context of their fear towards mutants in spite of coexistence with the aforementioned group.
* FridgeHorror: The end of "Bloodlines" has the High Command of the Friends of Humanity chastise Graydon Greed for his failure to kill off his mutant family members, but give him "one final chance" to redeem himself by assigning a mission to kill Sabretooth, his father. Given that Sabretooth is also implied to have ''horribly abused Graydon'' to the point that he inspired his hatred of mutants and created the organisation, that Graydon Creed is still deathly afraid of him (more so because he doesn't age, and is still a man in his prime), and that Sabretooth is seemingly bemused (if not displeased) that his son who became in his words "the infamous slayer of mutants" is now in front of his doorstep, it seems less of an assignment to Graydon Creed, and more of [[YouHaveFailedMe a death sentence for his failure]].
* GeniusBonus: Magneto once said to Wolverine, Cyclops and Storm "Oh, brave new world that has such people in it!" That quote is taken from the book ''Literature/BraveNewWorld'' by Aldous Huxley, which in turn cites Creator/WilliamShakespeare in-story for that quote. Or it may be directly a quote to Shakespeare; but in any case the words do not belong to Magneto.
* HilariousInHindsight: In "The Phalanx Covenant" two-parter: While taking over the Earth, the Phalanx intend to assimilate mutant powers to further their goals. Beast shudders at the thought of (essentially) one being having every mutant power on Earth. Flash forward a decade later to the ''New Avengers'' arc, "The Collective"...
** In the unaired pilot episode ''Pryde of the X-Men'', Wolverine has a [[http://www.youtube.com/watch?v=Q4d7TEvwznA noticeable Australian accent.]] Now ''[[Creator/HughJackman who]]'' portrays Wolverine in the [[Film/XMen film series]]?
** Wolverine's [[IfYouEverDoAnythingToHurtHer threat to Cyclops after he marries]] Jean, warning him "If she's not happy, make sure I don't find out." Considering what Cyclops does with Emma Frost, with Jean finding out...
** In the alternate timeline where the X-Men never were, due to Xavier's death, the familiar heroes are battling the human forces, leading to the eventual deployment of "the first wave of superhumans" against the mutants, which are {{cameo}}s of ComicBook/TheAvengers. A decade and a half later, a CrisisCrossover takes place titled, ''ComicBook/AvengersVsXMen''...
** The Storm-focused "Storm Front" two-parter has Storm become engaged to Arkon, a seemingly affable alien ruler, but Wolverine and Beast consider Storm's acceptance to be too quick; when Storm refers to Arkon as the man she loves, Wolverine quips, "who you just met." The series' DVD releases were licensed by Creator/{{Disney}}, who later released [[Disney/{{Frozen}} a movie]] with a very similar line and theme, and which similarly focused on a main character with ElementalPowers.
*** Comic fans also had a similar experience when [[ExecutiveMeddling Marvel Editors]] decided to suddenly [[StrangledByTheRedString retcon a backstory]] between Storm and ComicBook/BlackPanther, in order to wed them.
* HoYay: Wolverine noticeably takes Morph's death harder than anyone else (after being perfectly willing to risk his own life to try and save him), and later makes sure to avenge him. When Morph comes {{back from the dead}} Wolverine is quite emotional (for him), and is far more determined than anyone else to bring him back home, even chasing him to South America before reluctantly accepting that he needed time alone. He was also quite happy to have him back in "Courage" and volunteers the two of them for a mission together as soon as one comes up. For his part, Morph "dies" trying to save him and specifically calls out to him when he calls for help in "Reunion." At one point he also, while declaring he'll kill all the X-Men, thinks of killing Wolverine and suddenly snaps back to his "good" personality.
* JerkassWoobie:
** Erik, so very much.
** James Hudson aka Vindicator, comes off as one. He took Wolverine leaving Alpha Flight very hard, which implies that they were at one point, very good friends. "Repo Man" has him essentially try to conscript Wolverine back into service by siccing Alpha Flight on him when he returns to Canada, but then he rants to him about him about him leaving. Heather implies that the whole situation with Logan caused him to act this way.
* MagnificentBastard: Apocalypse is behind EVERYTHING.
* MemeticMutation: "I'm the Juggernaut, bitch!"
** "I am as far beyond mutants as they are are beyond you!"
** "The wild man of Borneo." <shifty eyes> "See you around."
** "Mmm, turkey!"
** PREVIOUSLY, ON X-MEN.
** "JEEEEEEEEEEAN!"
** [[https://www.youtube.com/watch?v=Ieog_e2tIvY COVERED WITH SCORPIONS...]]
** His wheelchair is clearly orange.
*** You mean yellow.
* NarmCharm: The cheesy voice acting often serves as one of the major draws for the show. Storm in particular is celebrated for being an over-the-top [[LargeHam Mistress of Pork.]]
** The ChristmasEpisode and the SeasonFinale are definitely guilty of this.
* NeverLiveItDown: Angel/Archangel's appearances entirely revolved around Apocalypse's turning him into a Horseman, and his vengeful streak afterward, apart from the very last example when he abandoned his obsession with revenge just in time for Apocalypse to try to ''[[InTheirOwnImage remake time and space into his own image]]''.
* NightmareFuel:
** What the Dark Phoenix did to Mastermind after she came out of his {{Brainwashing}}.
** The Shadow King.
** That... thing that was imprisoned in a Shi'ar starship that crashed on Earth. It eats ''souls''.
** Everything about Bishop's BadFuture. [[FridgeHorror The worst part about it?]] No matter how many times Bishop (and later Shard) travel to the [[TheNineties past]] and set right what went wrong, ''[[FailureIsTheOnlyOption nothing changes]]''. Plus, that time era's Forge has ''Wolverine's bare skeleton suspended in a tube''.
** A montage was put together of what would happen if Phoenix/Dark Phoenix were allowed to run amok. The results were fire covering the entire Earth. Sleep tight, kiddies.
** The effects of the Legacy Virus. It makes circuits appear all over your skin.
** The first episode of the Phoenix Saga ends with Jean Grey essentially being burned alive; the scene cuts out on her agonized screaming, and then the screen fills with a particularly scary-looking version of the Phoenix...
* OneSceneWonder: Apocalypse making such an impression whenever he shows up can make it easy to forget that he only appears once a season.
* PeripheryDemographic: Despite running as a Saturday Morning kids show, the material did not shy away from the darker content of the comics and thus continued to appeal to older comics fans as well.
* TheScrappy: Warlock from the "Phalanx Covenant" story arc. He was just an annoying voice attached to a silly alien belief structure that was reminiscent of nothing more so than Rolf from ''WesternAnimation/EdEddNEddy''.
* SuspiciouslySimilarSong: One of the Japanese intros to the show ("Rising"/"Shock") is heavily influenced by "Rising Force" by Music/YngwieMalmsteen.
* TearJerker: So, so many.
** The BadFuture montage stands out as it depicts something fans aren't used to: the X-Men losing. Bishop narrates events from his perspective of the 1990s forward to his time (2050s), in which Senator Kelly is assassinated, the Mutant Registration Act passes and Sentinels are deployed to "enforce" the Act. Then the Sentinels decide they could take over, and smash into the White House. The scenes of Bishop's future show captured X-Men being herded into concentration-style camps and end with a cemetery of dead X-Men. Probably the most evocative image was the close-up of Jubilee's grave, which is the last to be shown, and reveals that she, the youngest member of the team, would be the first to die... if they don't stop Senator Kelly's assassination in the first place.
*** "Beauty and the Beast."
*** The episode "Repo Man" counts once you realize the whole episode was about a couple who in the past helped a traumatized man (Wolverine) rebuild his life, have him join a government-sponsored superhero group that they just happened to work for to give him a sense of purpose, with said man having forged a deep friendship with the team, only for their relationship to somehow go sour just before he left Canada to join the X-Men. It got to a point where they tricked him into returning to Canada, just so that they can work together again, despite the fact that Wolverine left on his own volition and Wolverine finding out the one he apparently liked the most (Heather) arranged the trap. After the team realise that Wolverine was not captured to rejoin the team, but to build another Weapon X, they work to free him, save for Vindicator, the very man who first helped him in the beginning, refusing to let Wolverine leave them again. When Wolverine defeats him, Heather begs him to spare his life, and while Wolverine accepts he makes it clear to them he's never coming back. As he escapes the facility, Heather stares on, realising that it may be the last time she ever sees Wolverine again, and perhaps wondering if he'll ever forgive her for taking advantage of his trust.
* WhatDoYouMeanItsForKids?: This show was pretty ambitious and revolutionary for it's time. It had actual plots and story arcs, characters could be KilledOffForReal, and serious subjects like death and bigotry were handled well
* TrappedByMountainLions: Professor X and Magneto are stranded in the Savage Land for almost the entire second season. For the most part, it rarely took up more than a minute or two per episode. These scenes did ultimately tie into the main story arc. Sauron and a few Mutates were introduced one-by-one to set up their roles in the season finale. Mister Sinister's machinations, the reason why mutant powers were disabled in the region, and the fate of Ka-Zar's tribe were also foreshadowed. On the other hand, Xavier and Magneto just seemed to be wandering around the area rather than trying to figure out what was going on or trying to escape[[note]]it wasn't until the season finale that they made a point of trying to reach the mini-jet that Xavier had flown there[[/note]], which contributed to the sense that these scenes were just there to take up time.
* TheWoobie: The whole cast has their moments:
** Nightcrawler after the events of "Bloodlines."
** [[spoiler:Morph]], during his second season subplot and any of his later guest appearances.
** The series' rendition of Kevin "Proteus" [=McTaggert=]. He's de-aged to teenagehood and his powers don't kill people any longer, so he's seen in a far more sympathetic light.

[[folder:[=YMMVs=] for the 1992 X-Men arcade game:]]
* AdaptationDisplacement: The video game is much better known the one-episode pilot ''Pryde of the X-Men'' it was spun off from.
* AwesomeMusic: The [[https://www.youtube.com/watch?v=wsf7foyXIt8 intro]] and [[https://www.youtube.com/watch?v=U-V2yvedY6U Stage 1 music,]] which both served to hype players up into playing the game to hear more.
* HamAndCheese: While the dialogue is cheesy, the actors seem to be hamming it up, especially since the remake required all voices to be re-recorded, so the new actors had to be made aware of what they were doing and be told that the cheesy dialog was kept on purpose.
* HilariousInHindsight: Among the game's stable of {{Mooks}}, there are [[PaletteSwap recolored]] Sentinels that sport a blue-and-orange paint job, first appearing in the second stage. Fast forward to the early 2000s and the fan-modded custom colors for ''[[VideoGame/MarvelVsCapcom2 MvC2]]'' and... [[https://www.youtube.com/watch?v=sZZUMjoxfZA "OH HE GOT DA MANGO SENTINEL!"]]
* ILikedItBetterWhenItSucked: It was announced that the dialogue would be re-recorded and the cheesy lines would be removed and replaced with more natural dialogue. As it was, the dialogue had to be re-recorded anyway due to legal issues with the original voices, but upon hearing the fans' complaints, the company making the port [[https://www.youtube.com/watch?v=uPrnh-zZwqc decided to keep all the cheese on purpose]] so the game would avert this.
* MemeticMutation: [[https://www.youtube.com/watch?v=IdAmkx8eAos "Welcome to DIE!"]] and [[FountainOfMemes the myriad other dialogue]] voiced by our favorite [[https://www.youtube.com/watch?v=gjuWKAMAlQU "Master of Magnet."]] The former was so notable, it was {{ascended|Meme}} ([[https://www.youtube.com/watch?v=5tl7Bbn5niI by none other than]] SelfDemonstrating/{{Deadpool}}) in ''VideoGame/MarvelVsCapcom3''.
** Then there's [[MostAnnoyingSound the sound Colossus makes]] [[https://www.youtube.com/watch?v=wPLpovcDujw when using his Mutant Power.]] The "WHOAAAAAARGH!" has become the unofficial rallying cry for [[http://www.magfest.org MAGFest]], after that sound reverberated through the arcade room one too many times. Shouting it at nearly any time will usually be answered with others shouting "WHOAAAAAARGH!" themselves.[[note]](In subsequent years, signage was put up around the convention hall kindly asking con attendees ''not'' to do that; guess it was more of a MostAnnoyingSound then they realized.)[[/note]] [[SugarWiki/MomentOfAwesome They even got]] Creator/NobuoUematsu [[https://www.youtube.com/watch?v=iBYjlggRLPE to do it on stage!]]
** "NOTHING moves the Blob!"
*** (''is moved'')
* NarmCharm
* SoBadItsGood: The cutscenes and dialogue, and possibly the simple gameplay. According to [[https://www.youtube.com/watch?v=u8QBiLxoJVQ IGN's video review:]] "Sometimes something is so terrible that it's fantastic, and that's more or less the case here."

[[folder:[=YMMVs=] for the X-Men anime series:]]
* SugarWiki/AwesomeMusic: The opening theme.
* CompleteMonster:
** Sublime and Kick, also known as the U-Men, are the {{Starter Villain}}s, and make the most of their limited screentime to stand out as truly horrifying monsters. A pair of [[FantasticRacism mutant-hating]] [[SerialKiller serial killers]], the U-Men are known for kidnapping mutants, [[WouldHurtAChild specifically young teens]], then sadistically butchering and vivisecting them, using their organs to upgrade their own cyborg army. Along with this, the U-Men gleefully test out an experimental serum on innocent mutants that transform them into abominations [[AndIMustScream in constant pain]]. When Kick fails at killing the X-Men, he wantonly opens fire on them along with the numerous teenagers and police officers in the area, trying to kill anyone he can. Sublime, having left Kick to his fate, returns with a powerful suit of armor and tries to kill the X-Men, before blowing himself up in one last attempt on their lives. The U-Men both spend their last moments proclaiming their hatred and disgust for all mutantkind, and were defined by these throughout the series, showing that [[HumansAreTheRealMonsters humans could be just as wicked as the far more powerful mutants of their world]].
** [[MasterOfIllusion Mastermind]], real name [[TheChessmaster Jason Wyngarde]], is the leader of the Inner Circle, a group of mutant supremacists, and is [[BigBad behind all the evil in the series]]. The one responsible for Jean Grey's rampage across a city and her own death by transforming her into [[PersonOfMassDestruction the Phoenix]], Mastermind [[FrameUp framed his former lover]], ComicBook/EmmaFrost, as responsible for Jean's death as revenge for [[EvilIsPetty Frost leaving him]]. Working with the aforementioned mutant-killing U-Men (who are unaware that Mastermind is a mutant), Mastermind fully endorses their crimes, and uses them to learn of a powerful mutant residing in Japan, where he uses his abilities to ingratiate himself into the lab staff of mutant researcher Yui Sasaki. Learning that the powerful mutant is Sasaki's own teenage son, [[WoobieDestroyerOfWorlds Takeo]], who has [[RealityWarper reality-warping powers]], Mastermind spends months secretly using his powers to MindRape the boy into near insanity. After the X-Men out him as the villain he is, Mastermind amplifies his psychological torture on Takeo, driving the boy into a [[AndIMustScream horrifying state of death-longing insanity]] as [[WithGreatPowerComesGreatInsanity his powers go out of control]]. While holding numerous X-Men, one of which is a barely trained young girl, hostage, and using his powers to torture Cyclops, Mastermind reveals he plans to unleash Takeo's powers on the world like he attempted with Jean Grey, then watch the worldwide destruction and chaos that unfolds before him. Believing himself and all mutants to be the MasterRace of the Earth, Mastermind committed all of his crimes with a [[FauxAffablyEvil polite and cheerful attitude]], treating his atrocities as his "right" to perpetrate for being at the top of the evolutionary food chain.
* HoYay: Between Cyclops and Wolverine. You'd have to be blind not to at least once think "will they just get a room already?"
* MoralEventHorizon: When the U-Men try targeting ''kids'' just to improve their power, you know they've gone too far.
* SurprisinglyImprovedSequel: While the entire thing being better than the [[WesternAnimation/WolverineAndTheXMen last X-Men show]] overall would be a bold claim, the handling of Cyclops in comparison has unarguably been greatly improved. Both have Cyclops at roughly the same stage in his life: He lost Jean and is still grieving. But, in ''WATXM'', Cyclops was largely just a moody loner who didn't deal with it properly. Here, however, he starts with minor DeathSeeker tendencies, but evolves to the point where he overcomes his despair. Largely, people prefer the way he's written here compared to the previous show (and compared to the films).
