''Uncanny X-Men'' is a comic book series starring the Creator/MarvelComics superhero team, the ComicBook/XMen. First published in 1963, it is the longest running X-Men comic book series, and was the franchise's flagship title for most of its run. Originally simply titled ''The X-Men'', for Marvel's collections and reprints the entire series is often referred to as ''Uncanny X-Men''.

''The X-Men'' was the original title for the X-Men launched by Creator/StanLee and Creator/JackKirby. Under growing anti-mutant sentiment, Professor Charles Xavier creates a safe haven for the growing mutant population and he recruits five young adults for a super-hero team, named the X-Men (for "extra power" or the X-Gene, which causes mutant evolution). The first volume of the book featured the five mutant heroes ComicBook/{{Cyclops|MarvelComics}}, ComicBook/{{Beast|MarvelComics}}, [[ComicBook/WarrenWorthingtonIII Angel]], ComicBook/{{Iceman|MarvelComics}}, and ComicBook/JeanGrey (originally Marvel Girl) as they battled not only villains, but increasing prejudice against mutants. This run also marked the first appearance of longtime X-Men foe ComicBook/{{Magneto}} and the Brotherhood of Evil Mutants. New characters such as Cyclops's brother Havok and Polaris (another of Magneto's children) were later introduced, and the series firmly established itself in the shared Franchise/MarvelUniverse via crossovers with ComicBook/TheAvengers. The title ran new material until issue #66 (March, 1970) before switching to reprints of old stories.

In 1975, the series was revived, with ''Giant-Size X-Men'' #1 introducing a new and more diverse team: now billing itself as ''The All-New All-Different X-Men'', new stories resumed with issue #94 featuring the new characters ComicBook/{{Storm|MarvelComics}}, Colossus, Banshee, Nightcrawler, Thunderbird ([[SacrificialLion briefly]]) and ComicBook/{{Wolverine}}, retaining only Professor X and Cyclops (and later Jean Grey, who would become Phoenix). Creator/ChrisClaremont took over writing duties, with Dave Cockrum and later Creator/JohnByrne as artists/co-plotters.

From issue #114 the series billed itself as ''The Uncanny X-Men'' on covers, though this wouldn't become an official title change until issue #142. This era included storylines such as the "ComicBook/TheDarkPhoenixSaga" and "ComicBook/DaysOfFuturePast".

Claremont had an extremely [[ComicBook/{{XMenChrisClaremont}} long run]] as writer, lasting until 1991, and codified much of what defines the X-Men in the modern age. After Byrne left the book Claremont worked with a succession of regular artists including Cockrum again, Paul Smith, John Romita Jr., Marc Silvestri and Creator/JimLee (who would become co-plotter). The team would continue to evolve as well, as some characters left and new characters were introduced, including ComicBook/KittyPryde, ComicBook/{{Rogue}} and ComicBook/RachelSummers; Magneto also made a HeelFaceTurn and took over leadership of the X-Men. The ''Mutant Massacre'' story prompted a huge shift in the team lineup with only Storm, Wolverine and Rogue remaining, while bringing in new members ComicBook/{{Psylocke}}, ComicBook/{{Longshot}}, ComicBook/{{Dazzler}} and a returning Havok. Later additions to the team included ComicBook/{{Jubilee|MarvelComics}}, ComicBook/{{Gambit|MarvelComics}} and long-time recurring character Forge.

After Claremont left, around the same time as the launch of the companion series ''ComicBook/XMen1991'', Jim Lee continued as co-plotter along with new artist Whilce Portacio until both departed to co-found Creator/ImageComics. Afterwards, writing duties passed to Creator/ScottLobdell, who became one of the most prominent creators on the X-Men books for much of the 1990s. During this period, the X-Men were split into two field teams with ''Uncanny X-Men'' featuring the "Gold Team" (while ''X-Men'' featured the "Blue Team") – this lasted until the ''ComicBook/AgeOfApocalypse'' event in 1995, after which the two titles began blending together. After Lobdell's departure he was followed as writer by Steve Skeates, and then by Alan Davis with Terry Kavanagh. In 2000 the ''X-Men: Revolution'' relaunch saw Claremont briefly return as writer.

In 2001, ''Uncanny X-Men'' became a secondary X-Men title as Creator/GrantMorrison's ''ComicBook/NewXMen'' replaced it as the flagship, written by Joe Casey and then Creator/ChuckAusten. The ''X-Men: [=ReLoad=]'' relaunch in 2004 then saw Austen shifted over to the adjectiveless title while Claremont once again returned as the writer of ''Uncanny X-Men'', carrying over stories and characters from his ''ComicBook/XTremeXmen2001'' title.

Creator/EdBrubaker became the new writer of ''Uncanny X-Men'' in 2008. After the ''Messiah [=CompleX=]'' crossover event he was succeeded by Creator/MattFraction who in turn was eventually succeeded by Creator/KieronGillen.

''Uncanny X-Men'' finally ended with issue #544 in 2011, after the crossover event ''Schism'' – it was immediately relaunched as ''ComicBook/UncannyXMen2011'', also written by Gillen. The series has been relaunched from #1 a number of times since; the [[ComicBook/UncannyXMen2013 third volume]] brought back original numbering for its final issue, ending at #600.

[[folder:'''Major Storylines in Volume One:''']]
* ''The Silver Age, or "First Class" Era'' (Issues #1 - 66)
** A critical and commercial also-ran compared to Lee and Kirby's other works, the series was cancelled at issue #66 and ran in reprints until issue #93.
* ''Second Genesis'' (''Giant-Size X-Men #1'')
** This issue introduces readers to Storm, Colossus, Nightcrawler and Thunderbird and brings back minor Marvel Universe characters such as Banshee, Sunfire and [[ComicBook/{{Wolverine}} some Canadian guy with claws]]. The issue famously ends with Angel asking "What are we going to do with thirteen X-Men?" This one-shot (written by Len Wein and penciled by Dave Cockrum) set the status quo for the X-Men for many decades to come.
* ''The Beginning of the "All-New, All-Different" Era'' (Issues #94 - 101)
** Angel's question is almost immediately answered in the issue following ''Giant-Size X-Men #1'' as he, Jean, Bobby, Alex and Lorna [[MyFriendsAndZoidberg (and Sunfire)]] all quit, leaving Scott as the sole remaining member of the original squad. The team lineup is shaken up even further with the death of Thunderbird at the hands of Count Nefaria and subsequent fallout of Scott letting a teammate die (#94 - 95) with the latter unwittingly unleashing a demon on the school in a fit of rage (#96), introduction of ArcVillain Eric the Red, who manipulates Havok and Polaris into attacking the new team (#97), capture of several X-Men by new and improved Sentinels and battle with Stephen Lang's X-Sentinels on a S.H.I.E.L.D. space-station, leading to Jean having to save the group by piloting a damaged shuttle on her own and dying, only to be reborn as the Phoenix (#98 - 101). Notable for introducing Creator/ChrisClaremont to the series, beginning a fifteen-year run on the characters.
* ''Further Adventures and Emergence of the Phoenix'' (Issues #102 - 110)
** Notable for featuring the first work of Creator/JohnByrne on the series.
* ''"Death" of the X-Men" and First World Tour'' (Issues #111 - 124)
** This run of issues is notable for Byrne taking over as penciller from Cockrum full-time and puts an emphasis on building the characters of the All-New, All-Different team members.
* ''The Proteus Saga'' (Issues #125 - 128)
** This arc sees Banshee leaving the team to recuperate from his injuries and has the All-New, All-Different team, Jean and Xavier return to New York.
* ''ComicBook/TheDarkPhoenixSaga'' (Issues #129 - 138)
** Considered maybe the most iconic storyline in X-Men history and introduced characters and concepts (The Dark Phoenix, Kitty Pryde, the Hellfire Club, etc.) that would define X-Men comics for decades. This story has been adapted in nearly every form of X-Men media, with ''Film/XMenTheLastStand'' and ''Film/DarkPhoenix'' taking cues from it directly.
* ''Welcome to the X-Men Kitty Pryde, Hope You Survive The Experience!'' (Issues #139 - 140)
** A short bridging gap between the two most infamous [[WhamEpisode Wham Episodes]] in Claremont's run, the issues are mostly notable for a short scene of Colossus uprooting a tree stump causing a dispute between Claremont and Byrne (Byrne drew it as Colossus easily tearing the stump free with Claremont deciding to write his inner monologue as struggling with the task) that led to the latter leaving the series after a landmark run.
* ''ComicBook/DaysOfFuturePast'' (Issues #141 - 142)
** Often considered a contender for "most iconic X-Men storyline" alongside ComicBook/TheDarkPhoenixSaga, Days of Future Past has been referenced in several X-Men media and was the basis for the 2014 film ''Film/XMenDaysOfFuturePast''. The idea of the X-Men fighting a dark future would come up time and time again in storylines over the years and the covers of both issues (#141 moreso than 142), would become homaged and parodied numerous times over the years due to Byrne's iconic visuals of Logan and Kate Pryde backed up against against a wall featuring all of the members of the X-Men labeled either "slain" or "apprehended" and a Sentinel frying a lunging Wolverine to a crisp with his hand cannon, respectively.
* ''Doom, D'Spayre and the Return of Magneto'' (Issues #143 - 150)
** #143 serves as the last issue pencilled by John Byrne, with the artist's swansong being a giant homage to ''Film/{{Alien}}'', which is fitting considering he designed Kitty to look like a young Creator/SigourneyWeaver. This run is also notable for seeing Cockrum return to pencils and Claremont beginning his redemption tour for the X-Men's greatest enemy: Magneto.
* ''Prelude to the Brood Saga'' (Issues #151 - 160)
** The events of Illyana's time in Limbo are later explored in the pages of ''ComicBook/NewMutants'' and her own limited series ''ComicBook/{{Magik}}''. See that series page for more details. Issue #159 is notable not only for being the first of many "Storm becomes a vampire" stories that will appear over the years, but featuring the first X-book work of Bill Sienkiewicz, who would go on to be the definitive artist of Claremont's second X-Men series: ''ComicBook/NewMutants''.
* ''ComicBook/TheBroodSaga'' (#161 - 167)
** The Brood Saga is notable for featuring the last art by Dave Cockrum (who reshaped the series in ''Giant-Size X-Men #1'') and the first by longtime artist Paul Smith. Major concepts such as the introduction of Lockheed the Dragon, Kitty and Colossus’ FirstKiss after several issues of teasing, ComicBook/CarolDanvers return to a powered state after losing her abilities and, most importantly, leads to Xavier forming his third class of students: The ComicBook/NewMutants. See that team’s page for more on the first X-Men spin-off running concurrently with Uncanny.
* ''ComicBook/GodLovesManKills'' (Marvel Graphic Novel #5)
** Written by Claremont and pencilled by Brent Anderson. Technically a one-shot outside of the main ''Uncanny X-Men'' title, ''God Loves, Man Kills'' sets a DarkerAndEdgier precedent for the mutant heroes directly confronting a world that hates and fears them. Stryker would go on to be one of the series’ most iconic villains without possessing any super-powers. The story was so influential that it would serve as inspiration for ''Film/X2XMenUnited'', the second film in the franchise.
* ''ComicBook/FromTheAshes'' (#168 - 175)
** These issues were yet another turning point in the series, with Rogue joining the team, Kitty adopting Lockheed as her constant companion, Storm adopting her iconic punk look, introducing the Morlocks and Madelyne Pryor (setting up future crossover events ''The Mutant Massacre'' and ''ComicBook/Inferno1988'', respectively) and serving as a follow-up to Wolverine’s solo limited series. In addition, #171 featured artwork by Walter Simonson, who would go on to serve as regular series artist on the book’s second spin-off ''ComicBook/XFactor''.
** [[ComicBook/Wolverine1982 The events of Logan’s solo adventure in Japan prior to #172 are detailed on its own trope page.]]
* ''ComicBook/{{Lifedeath}}'' (#181 - 188)
** These issues take place after the events of ''ComicBook/SecretWars1984'', and focuses on the US Government taking steps to deal with Mutantkind, with massive consequences. It features the first appearance of Forge, the depowerment of Storm, and Rachel Summers joining the X-Men.
* [[ComicBook/UncannyXMenChuckAusten Chuck Austen's run as writer]] (#410-443).

* ''ComicBook/UncannyXMen2018''

!!The first volume provides examples of the following tropes:

* AbortedArc: During Brubaker's run, it's implied Magneto hasn't actually lost his powers after M-Day. When he reappears in ''X-Men: Legacy'', a few years later, and following on from that in ''Uncanny'' issue #500, he is confirmed to still be depowered.
* AcademyOfAdventure:
** Xavier's School for Gifted Youngsters.
** An EvilCounterpart called the Massachusetts Academy was run by Emma Frost and essentially served as a recruiting tool for the Hellfire Club. Kitty Pryde’s first issue sees Emma offering a (failed) counteroffer to her parents to join her school.
* ActionDressRip: Jean has to do one of these in issue 98. Dresses designed for formal dinners are not designed for running from killer robots. She proves unable to do it, so Logan does it for her.
* AffablyEvil:
** As always, Doctor Doom. He and Storm have dinner while the other X-Men sneak through Doom's dungeons to free Arcade. Storm actually ''regrets'' that she's a distraction, because she's ''enjoying herself''. Hell, Doom secretly ''knows'' what she's doing and carries on anyway!
** Dracula appears, transforming Storm into a vampire in #159. Though he fully intends to make the transformation permanent he changes his mind and allows Storm to regain her humanity when she proves to be such an impressive figure that he can't bring himself to strip her of what makes her unique.
** Part of Magneto’s characterization involves him becoming this, with his tragic past being revealed in #150 and all further dealings with the X-Men up until the 90s involving him treating the heroes with utmost respect and eventually making a HeelFaceTurn to join them.
* AintTooProudToBeg: Stephen Lang begs Scott and Jean to save him not even seconds after he'd tried to kill them, and after having monologued about how he wants to exterminate all mutantkind.
* AliensSpeakingEnglish: Invoked, and blatantly [[LampshadeHanging lampshaded]] when the X-Men first meet the Starjammers.
-->'''Nightcrawler:''' You speak English?
-->'''Ch'od:''' Doesn't everyone?
** The style of English they speak varies. Ch'od speaks normally. Hepzibah [[YouNoTakeCandle speak in broken English]], and Raza uses mangled Elizabethan English.
* TheAllegedCar: On their first visit to Cassidy Keep, the X-Men are forced to endure a mix of Banshee's driving, Irish back-country roads, and a car with awful suspension. Everyone rags on Sean and the car the whole journey.
* AndIMustScream: Doom turns Storm to a metal statue, but leaves her mind perfectly intact. Storm has a severe claustrophobia, and this kicks it into overdrive. As in, "drives Storm utterly batshit insane".
* AndNowYouMustMarryMe: The Morlocks abduct Kitty to try and force her to marry Caliban. It's called off when Caliban realizes Kitty doesn't love him.
* AntiHero: Numerous over the years:
** During Claremont's first run, Wolverine made no secret of the fact that he didn't abide by the ThouShaltNotKill rule.
** Thunderbird was also this to his detriment, as the writers didn’t know what to do with the similarly grizzled hero with Wolverine on the squad and deciding it was easiest just to kill him off.
** Warpath in Brubaker's run. A nice, genial guy all around, but he also has two ''very'' big Vibranium knives which he can and will use on folk.
** One of the biggest would be Emma Frost during Fraction's run, who was part of Norman Osborn's Cabal.
** Doubly so for Namor, who was part of both the Illuminati ''and'' the Cabal during both the Fraction and Gillen runs.
** The Utopia era sees Cyclops progress further and further into Anti-Hero status before undergoing a full-on FaceHeelTurn (unless one was RootingForTheEmpire against the Avengers) during ComicBook/AvengersVsXMen.
* ArcVillain:
** Lucifer, the alien responsible for paralyzing Xavier, is the first in the series, serving as an overarching villain across the first several issues.
** The mysterious organization Factor Three, led by the Mutant Master, serves as this during Roy Thomas's run.
** Erik the Red from issue 97 to issue 105 (barring a few issues off to let Steven Lang - [[ComicBook/AntMan no relation]] - take center stage). He turns out to be TheHeavy for the Mad Emperor D'Ken.
** The Hellfire Club begin twisting things in their favor in 110, when they hire Warhawk to plant surveillance devices throughout the mansion. Their agent Mastermind spends the next few dozen issues psychically guiding Jean Grey towards becoming Black Queen of their organization and they eventually make their full presence known at the beginning of the Dark Phoenix Saga before being supplanted by the titular figure as the story's BigBad.
** The Brood make their appearance known upon Corsair's return to Earth and continue as antagonists in the Brood Saga that lasts until issue 167.
** Mastermind returns to manipulate events between 168 and 175, striking out for revenge against the X-Men in plots that range from the petty (like convincing Mariko that Logan is unworthy so that she’ll call off his wedding) to the petty, but more dramatic (like tricking the team into thinking that Madelyne Pryor is the Dark Phoenix reborn and launching yet another attack on humanity).
** Loki is the mastermind of the Asgardian Wars storyline, in which the X-Men and Alpha Flight thwart his attempt to con his way into ultimate power, he sends the Enchantress after the New Mutants in revenge, and the X-Men come to the nine realms to rescue the kids.
* ArsonMurderAndJaywalking: In issue 500, when an "artist" decides that setting up a display involving ''Sentinels'' in the city where mutants have made their home is a good idea, we get a nice one.
-->'''Angel:''' Sadie, come on! Twenty-foot-tall '''death machines--'''\\
'''Beast:''' Genocidal robots no more artful than an A-Bomb--\\
'''Emma Frost:''' Banal, predictable "shock schlock" that was passé in New York ten years ago--\\
'''Wolverine:''' Hell with this.
* ArtisticLicenseReligion: Nightcrawler's (later-retconned) priesthood falls under this. While his being a mutant would be no impediment under canon law (to be fair, canon law has never had to talk in favor of or against blue-furred, three-toed teleporting mutants), ordination as a Catholic priest is not a part-time job. A seminarian goes through four to eight years of college-level studies and then completes an internship at a parish before ordination begins, which is not a lifestyle conducive to being a swashbuckling superhero.
* AuthorAppeal: Things Chris Claremont likes to use in his stories; Brainwashing, BodyHorror, women in skimpy outfits inflicting brainwashing and / or BodyHorror, Storm being courted by AffablyEvil villains (and Storm in general), women trying to corrupt younger female characters, and any combination of the above.
** Also, PurpleProse. Sometimes this is either through villains monologuing or heroes retorting with monologues of their own or even the narration going on tangents to monologue about the characters' foibles. Podcast/JayAndMilesXPlainTheXMen even has the "Angry Claremontian Narrator" as a side character (and a rather dickish one at that) due to its prominence during the Bronze Age.
* AuthorCatchphrase: Chris Claremont has a few. Such as Psylocke talking about "the focused totality of [her] psychic powers!"
* AvengersAssemble: Giant-Size X-Men #1 (the first new issue after the series was cancelled) features Charles Xavier recruiting Nightcrawler, Wolverine, Banshee, Storm, Sunfire, Colossus and Thunderbird in a series of brief introductions. It’s not until after they’re all assembled that we find out ''[[RescueArc why]]'' Xavier has brought them together.
* BackForTheDead: After being in a coma for three decades, D'ken finally returns in Brubaker's run. Then, after a few issues, Vulcan fries him to a crisp.
* BadassNormal:
** Dr. Peter Corbeau, an old friend of Charles', has no problem (or difficulty) acquiring a space shuttle for the X-Men to fly into space, then pilots it while under attack from Sentinels.
** Honorable mention to [[Characters/XMenMutants Moira MacTaggert]], who in her first appearance witnesses a demon smash through the wall of the mansion... and instantly grabs an assault rifle.
** ComicBook/CarolDanvers becomes an honorary member of the team for several issues after losing her powers at the hands of Rogue before gaining her Binary abilities during the Brood Saga and flying off to space to join the Starjammers.
* BadBoss:
** The Badoon King in annual #5, who vaporizes an underling for bringing him bad news.
** The Brood Queen, who seemingly couldn't go a single scene without threatening her own soldiers.
* BadFuture: Days of Future Past, the quintessential X-Men example, debuted in issue 141.
* BashBrothers:
** Hank and Bobby were commonly this while Scott, Jean and Warren angsted over their love triangle incidents during the Silver Age.
** Logan has moments with both Nightcrawler and Colossus and later on with Psylocke after her body swap.
** Juggernaut and Black Tom Cassidy form a villainous variant.
* BatFamilyCrossover: Became more prominent during the 80s when series such as the ''ComicBook/NewMutants'' and ''ComicBook/XFactor'' began to expand the Marvel Universe. This was kept pretty mild with stories such as ''The Mutant Massacre'' and ''ComicBook/Inferno1988'' until the 90s when the myriad books basically became small pieces of a larger whole leading to the next major crossover.
* BattleCouple: Due to the heavy soap opera elements, a number of these exist throughout the series’ history:
** Scott and Jean finally admit their feelings for each other during the Silver Age issues and remain a couple up through ''ComicBook/TheDarkPhoenixSaga'' where they make their last stand together on the Moon.
** Colossus and Kitty strike up a flirtation early on that blossoms into full-blown romance during ''ComicBook/TheBroodSaga''. Though they do break up after ''ComicBook/SecretWars1984'' the Kitty/Colossus relationship is a well many authors would return to over the years.
** Havok and Polaris try to avert this by leaving heroics and attending college but they are inevitably pulled back into the X-Men’s circle against their protests.
** Scott and Alex’s dad Corsair shares this trait with his sons, forming a long-lasting relationship with his fellow SpacePirate (and snarky alien skunk/cat lady) Hepzibah as members of the Starjammers.
** Though it would only be confirmed after a retcon years later -- plus decades and ''decades'' of not-so-subtle hints -- ComicBook/{{Mystique}} and Destiny form this as members of the second Brotherhood of Evil Mutants.
* BattleInTheCenterOfTheMind: Issue #117 details Charles' first meeting with Amahl Farouk, where they have one of these. To the people in the café they're in, the two stare at one another for several minutes, then Farouk slumps over dead.
* BeautyIsNeverTarnished: When in the Savage Land, no matter how long they're there or how rough the conditions, no X-Woman will ever get scratched or dirty or dishevelled in the way the men do. Case in point, the first time the All-New team stay there, Scott gets scruffy enough to start looking like Corsair. Storm... looks like she just stepped out of the shower.
* BerserkButton:
** An early one of Logan's was hurting women.
** Don't hurt Moira Mactaggert around Banshee.
** Racism of any sort -- though primarily anti-mutant or antisemitic -- is a quick way to get Kitty Pryde unleashing hell on you.
* BigBad: Magneto held this title for about the first 150 issues, until he started making his HeelFaceTurn and eventually joined the team outright. If it wasn't him, then the Hellfire Club or the Shadow King were top contenders for the X-Men's biggest nuisance.
** While Magneto remains the ArchEnemy in the early issues of Claremont's run, his appearances are considerably less frequent than in the pre-Claremont era, with Sebastian Shaw serving as the most overarching BigBad starting from issue 110 for about a hundred issues.
** Mister Sinister takes on the role from Mutant Massacre through Inferno, and is consistently one of the most prominent villains in the franchise from that point onwards.
* BigBrotherInstinct: Colossus' powers first manifest when he sees a tractor bearing down on his little sister, and he thoughtlessly rushes into its path to save her (neatly helping to establish that Piotr loves his sister, but has a tendency to not think about anything else when she's in danger).
* TheBigGuy: Due to the series being a LongRunner, there have been a few through the years:
** Beast started out this way in the first few issues until his characterization as a GeniusBruiser set in and he took his permanent role as TheSmartGuy of the X-Men.
** Colossus for the All-New, All-Different team. Thunderbird was this for a couple of issues before being KilledOffForReal and Rogue would later join to help Colossus fill this role after permanently gaining the powers of ComicBook/CarolDanvers.
** Bishop, in Claremont's second run.
** Warpath, during Brubaker's run.
** Namor and Colossus during Matt Fraction's run.
* BlessedWithSuck: On occasion, a mutant comes along who doesn't get eye-beams, weather control or fantastic mind control powers, but something just kind of "eh", or worse. Rogue is a famous example, being unable to touch anyone without draining the life out of them, but a lot of the Morlocks have it almost as bad.
* BodyHorror: During ''Rise and Fall of the Shi'ar Empire'', the team finds some bodyguards of an abandoned Shi'ar facility who were once human, until the Shi'ar turned them into cyborgs via horrific invasive surgery. Warpath considers killing them via knife to the brain a MercyKill.
* BrainwashedAndCrazy: Happens a ''lot'' (see AuthorAppeal).
** Havok and Polaris spend a good dozen issues brainwashed by Erik the Red, then the entire team gets brainwashed by Mesmero.
** Jean's brainwashing at the hands of Mastermind during ''ComicBook/TheDarkPhoenixSaga'' is what leads her to join the Hellfire Club as the Black Queen and go full on Dark Phoenix and become a threat to the cosmos at large.
** ''The Muir Island Saga'' has a lot of the team brainwashed by the Shadow King, using Polaris and Legion.
* BreakingTheFourthWall: During the early days of Claremont's run, Scott and Jean have ''finally'' gotten over their unrequited crush, and make out. A passing man named [[Creator/JackKirby Jack]] talks to his friend [[Creator/StanLee Stan]] about how "they never used to do '''that''' when '''we''' had the book."
* BreakoutCharacter:
** Wolverine is probably the biggest example, but Storm could also count.
** Judging by her prominent status as leader of the X-Men after years of being the TagalongKid, Kitty Pryde is this for many people.
* BreakTheBadass: Proteus manages to destroy Wolverine. Cyclops has to taunt and enrage him in order to rekindle Logan's fighting spirit.
* TheBusCameBack:
** Brubaker's run had Deathbird return after last being seen getting tossed out of an airlock. She'd been imprisoned by the Shi'ar some time afterward.
** Matt Fraction's run has Magneto recover Kitty from space, after she'd gotten stranded out there at the end of Joss Whedon's ''Astonishing X-Men''.
* CainAndAbel:
** Juggernaunt (Cain... Marko) to Charles (Abel).
** D'Ken (Cain) to his little sister Lilandra (Abel). And then their sister Deathbird(Cain), who murdered another sister of theirs.
** Havok (Cain) to Cyclops (Abel) any time he's brainwashed. Which is a surprising amount. Then, during Brubaker's run, Havok is the Abel to Vulcan's Cain.
** Colossus (Abel) and Magik (Cain) can have this from time-to-time when Illyana gives in to her Darkchylde persona. Their older brother Mikhail similarly jumps back and forth between Cain and Abel status when he shows up in the 90s run; typically settling on the former as an antagonist.
* TheCaligula: D'Ken of the Shi'ar Empire, often referred to as “The Mad Emperor”. His madness and quest for power lead him to nearly destroy the entire universe. He gets driven completely insane for his troubles, and disappears from the title for three decades.
* CaptainEthnic: Though every new recruit for the All-New, All-Different was defined in their introduction by their country (or culture) of origin, some were far more defined by their nationality than others:
** Sunfire (a member for all of one issue, in which he quit roughly three times) wore the Japanese Rising Sun on his uniform, constantly declared allegiance to his homeland and gained his powers from his mother being exposed to radiation from the atom bomb dropped on Hiroshima (this was an example of EarlyInstallmentWeirdness when mutants got their powers from radiation, instead of mutation).
** Thunderbird (who similarly only lasted a few issues before being killed off) was defined completely by his Apache heritage and hatred of the “white man” for what they did to his people. His costume consisting of BraidsBeadsAndBuckskins and codename being taken from a Native American spirit helped heighten the ensemble.
** Banshee was similarly defined by his Irish heritage more than anything else early on thanks to his red hair, FunetikAksent and codename and power being taken from the classical Irish wailing spirit. Due to sticking around for far longer than the previous two members he was able to gain a number of shades to his personality that had nothing to do with his heritage and become far more well-rounded (an incident with Leprechauns, notwithstanding).
** Colossus was similarly defined by his Russian heritage a great deal early on. His status as a “Man of Steel” (which was the literal translation of Joseph Stalin’s name), last name of Rasputin and early explanations of his atheist upbringing marked him as a child of the USSR. The X-Men’s first encounter with Arcade had the villain {{Gaslighting}} him into thinking that he had betrayed his homeland and he became “The Proletariate”, a defender of the working man intent on crushing Western civilization. Luckily, he snapped out of it the next issue and returned to his previous ideology.
** Nightcrawler largely avoided this aside from his use of GratuitousGerman. Seeing as Dave Cockrum initially designed him as an alien character for DC Comics before applying the German nationality to him when he recycled him for the X-Men, it makes sense that little of the country’s national stereotypes inhabited his character.
** Storm and Wolverine were the least defined by their nationality, with the former’s pan-African upbringing (she was born in Harlem, spent her early years in Cairo after her parents deaths as a pickpocket before traveling to her mother’s homeland in Kenya) and latter’s Canadian nationality only coming up as plotpoints and not character markers. Of course, whenever Logan does end up in Canada he typically runs into Alpha Flight, a team of nothing but CaptainEthnic representatives of MooseAndMapleSyrup.
* CategoryTraitor: Sebastian Shaw, Black King of the Hellfire Club is a mutant. He’s also the head of Shaw Industries, a corporation manufacturing Sentinels built solely to hunt down and kill mutants. It’s implied at the end of ''Days of Future Past'' that Shaw’s dealings with Project Wideawake helps set the bad future in motion by turning on his own kind to make a profit.
* ChangedMyMindKid: Sunfire quits the rescue mission to Krakoa before the team can even board the jet and rejoins later ''on the same page''. He quits for good in the following issue, making it a strange kind of character tic.
* CheerThemUpWithLaughter: In issue # 192, Nightcrawler tries to cheer up Rogue by tickling her.
* ChekhovsGun:
** Through issues 98, 99 and 100, mention is repeatedly made of an incoming solar flare. This is the reason the Sentinels don't catch all the X-Men, and is responsible for the birth of The Phoenix.
** During their first encounter with the Brood (who have been hired by Deathbird to kidnap her sister Lilandra) Xavier begins experience psychic attacks involving a disturbing alien face. This is setting up the fact that he has been implanted with a Brood Queen egg, which comes into play during the Brood Saga about a dozen issues later.
* ChekhovsGunman:
** Xavier keeps seeing psychic flashes of a bug-eyed alien approaching Earth throughout early issues featuring the All-New, All-Different team. This figure is later revealed to be Lilandra, the escaped princess of the Shi'ar Empire.
** After the All-New team's first encounter with Magneto, as they flee Wolverine notes one of the cells on Muir Island has been damaged, but doesn't mention it. Several issues later, the occupant of that cell gets out.
** Amahl Farouk, shown in a flashback to be Charles's StarterVillain in his past, and who is apparently killed in their first encounter. He later turns out to be not so dead after all.
* ChickMagnet: Cyclops. Jean Grey, Coleen Wing, Aleytis Forrester, Madelyne Pryor and Emma Frost all want him.
* CliffhangerCopout:
** The end of issue 100 ends with Jean flying a space shuttle, as horrifically deadly amounts of radiation get in. And the cover, the very ''cover'' of issue 101 reveals that, yeah, she's fine. Better than fine, actually.
** Halfway through ''ComicBook/TheDarkPhoenixSaga'' Cyclops seemingly dies during a psychic duel with Mastermind, leading Nightcrawler to exclaim "Cyclops is dead!" The next issue presumably takes place no less than ten seconds later with Cyclops being shaken, but ultimately fine.
** One issue ends with Bishop suddenly turning around and shooting the entire team. The next issue begins with it turning out they're all fine - he'd noticed they'd been doused with killer nanobots and was getting rid of them, but he didn't have time to warn everyone.
* ColonyDrop:
** In their fight with Jahf, Jean tries grabbing a passing asteroid and dropping it on his head. It doesn't do anything.
** Moses Magnum attempts to do this with the entire island of Japan. Luckily, Banshee disrupts his plan with a massive sonic scream that blows out his powers for quite some time, forcing him to quit the team.
* ComicBookTime: Wasn't too much of an issue early on, with the X-Men following most of the same rules as the rest of the Marvel Universe. As established historical events become more dated such as Xavier fighting in Korea it became more difficult for writers to consolidate the events and a more broad strokes approach was taken, much like with Tony Stark's original Vietnam origin being updated to the modern era.
** Averted with Magneto, however, as his origin -- much like Captain America's -- has become inextricably linked to WWII and the Holocaust. Writers have gotten around this due to a rather goofy plotline from the Silver Age of Magneto being de-aged and re-aged to the prime of his life, making it less outlandish that the X-Men would be fighting a centenarian in the modern age.
* ConservationOfNinjutsu: During the ''[[ComicBook/XMenSecondComing Second Coming]]'' crossover, a big one was that the Nimrod sentinels were being taken down remarkably easily, to the point where two X-Men could take one down together, and Namor could take ''three at a time''. One Nimrod used to be able to take an entire X-Men team.
* CoversAlwaysLie: In that bombastic Silver Age style, the cover of issue 100 proclaims it's the Original X-Men versus the All-New team. This is not really true.
* CreatorCameo:
** Stan Lee and Jack Kirby make an appearance in an issue of Claremont's run.
** When Jean faces Firelord, he is sent flying, and a man tells his friend Dave that "he hits the ground with this incredible sound effect" just as Firelord hits the ground. While running away, he asks if Dave is still listening, to which Dave says "[[SelfDeprecation Chris, do us all a favor -- shut up and run!!]]" Dave is clearly supposed to be Dave Cockrum, the artist on ''The X-Men'' at the time, and the man is Chris Claremont himself.
* {{Crossover}}: A few, here and there.
** The X-Tinction Agenda, which crossed between this title and ''New Mutants'', focusing on the revenge of the evil Genoshan government on the X-Men.
** In the mid-500s, there's a crossover with ''Fear Itself'', featuring the team trying to stop an even more unstoppable than usual Juggernaut.
* CrossThrough: Early on in Claremont's run, just after Jean becomes Phoenix, she starts rooming with Misty Knight, who by [[BlatantLies mysterious coincidence]] was created and written by Chris Claremont. Fancy that. During the X-Men's visit to Japan, they run into her friend / partner Colleen Wing, also created by Chris Claremont. And the introduction of Stephen Lang has a brief appearance by Michael Rossi, a supporting character in the contemporary ''[[ComicBook/MsMarvel1977 Ms. Marvel]]'', which was written by... Chris Claremont again. In the run-up to issue 150, the gang has a brief moment where Spider-Woman is suddenly staying at the mansion. Guess who was writing her title ''then''.
* CurbStompBattle:
** The all new, all different team's first encounter with Juggernaut, due to a combination of lack of experience and his sheer ability.
** Likewise, their first encounter with a rejuvenated Magneto, who lacks the insanity that characterized him prior, and mops the floor with them. Only Cyclops manages to save them, and the team makes a break for it.
** Any fight with the Shi’ar Imperial Guard was characterized as this, with the X-Men’s inability to quit against the overwhelming force of the alien super-beings always earning their respect.
* CuttingTheKnot:
** Faced with an out-of-control Danger Room, and a big control panel of indecipherable switches, and a little groggy from getting teleported, Wolverine decides the best way to fix the problem is scratch it up. That works.
** In issue #150, Kitty has to deal with the control systems for Magneto's computers. Problem is the conviniently handy book is written in a foreign language she doesn't know and probably in code on top of that. So she just smacks the hell out of the thing with a chair.
* DeathIsCheap: On occasion.
** Professor X supposedly dies battling an angry member of a subterranean species with a grudge against mankind. It soon turns out he'd faked his death, and the person who'd died was the shapeshifter Changeling imitating him.
** The entire team dies fighting The Adversary. The goddess Roma brings them back to life.
** Donald Pierce gets his head punched off by Sebastian Shaw. It didn't take.
* DeathOfTheHypotenuse: Wolverine seriously speculates letting this happen to Cyclops at one point (in the middle of mellowing out from "total asshole" to "mild asshole"). He decides that shooting Scott in the back isn't his way, and if it ever comes to it, he'll do it face to face, and shoves Scott out of the way of the incoming razor-blades.
* DecoyBackstory: The series once introduced a supposed new team of X-Men, each with their own backstory (Crux was a French figure skater, Rapture was a nun, Chaos was autistic, etc.) [[spoiler:Absolutely none of their backstories were real; they all turned out to be nanotech constructed created by Cerebro.]]
* DeliberateValuesDissonance: Storm, in her early days, what with having first grown up as a thief in Cairo, then spent some time being worshipped as a god in Kenya, hasn't quite got the idea of "clothes". An unseen incident involved her swimming naked in the mansion pool, and not understanding everyone else's reaction.
* DisneyDeath:
** Two-ways. The entire All-New, All-Different team save for Jean and Beast after their second fight with Magneto leaves the groups separated by a wall of magma. Jean and Hank go home to inform Xavier that Scott, Ororo, Piotr, Kurt, Logan and Sean have died when they're actually safe and sound in the Savage Land thinking that Jean and Hank were the ones who died.
** The entire team during "Fall of the Mutants", with, for a while, the entire world thinking the X-Men were dead. It also led to Nightcrawler and Shadowcat moving to England and forming Excalibur.
* DisneyVillainDeath: Happens from time to time.
** Sauron's second appearance has Karl Lykos plunge over the edge of a cliff face. It took a few years before he reappeared, having survived and made his way into the Savage Land.
** Juggernaut and Black Tom's fight with the All-New X-Men ends with Tom falling into the storm-tossed sea around Cassidy Keep, and Juggernaut leaping after him. They turn up again.
* DisproportionateRetribution: In a training exercise, Logan tries to kill Colossus because he pushed him out of the way of a falling pillar, thus "cramping his style"... Douche.
* DirtyMindReading: Subverted, when Rachel infiltrates the Hellfire Club. She picks up some of the thoughts of a few members, and the minute she's alone has to keep from doubling over with laughter at whatever it is she's read.
* DoesNotKnowHisOwnStrength: When the All-New X-Men (and Jean) play baseball, Jean catches a hit of Piotr's, informing him the last time he sent a ball flying, he broke a window. Of an airplane in flight.
* DragonLady: Miss Locke for Arcade. She literally used the codename Dragon Lady.
* DyingAsYourself:
** Jean kills herself to stop Dark Phoenix from getting out of control.
** Xavier attempts to commit psychic-assisted suicide when he's [[spoiler:infected with a Brood Queen egg.]]
** When she's infected with a Brood egg, Storm tries to commit suicide in the vacuum of space.
* EarlyInstallmentWeirdness: See the separate trope page for details.
* EasilyForgiven: Doctor Doom turns Storm to metal, which sends her into a psychotic rage. Once everything's over and she's stopped trying to char-grill her friends, she just lets Victor (who at the time was no longer undisputed ruler-for-life of Latveria) go on his merry way with a "no harm done". In fairness, the X-Men were big on ThouShaltNotKill.
* ElaborateUndergroundBase: Magneto has one early in the Claremont run, built underneath a volcano. Man's got style. It gets destroyed thanks to the X-Men breaking free. That, and the lava everywhere.
* EndOfAnEra: "ComicBook/TheMuirIslandSaga" ended Claremont's first, seventeen year run on the title (he left before it actually finished, due to behind-the-scenes stuff), crossing over with ''X-Factor''.
* EnemyMine: Averted. Magneto almost kills Mesmero for ''daring'' to defeat the X-Men.
* EstablishingCharacterMoment: ''Giant-Size X-Men'' #1 shows off the All-New, All-Different team’s membership in a series of brief scenes as they are recruited to the Xavier Institute.
* EvilCounterpart: Claremont's absolute last issue of ''Uncanny'', in the mid-00s, introduces the First Forsaken, a sort-of-counterpart to the Phoenix. "Sort-of" because literally everything Phoenix related afterward has ignored its existence entirely.
* EurekaMoment: During the first fight with Jahf, Banshee catches note of him mentioning circuits, and figures the little guy is a robot, which gives him the inspiration to defeat him.
* EyeScream: During his fight with the Shi'ar Imperial Guard, Vulcan gets his left eye punched out by an angry Gladiator. It remains punched out for the rest of Vulcan's life, despite his ability to regenerate from anything.
* FacialHorror: Masque of the Morlocks likes using his powers to inflict this on folk, mainly because he's a dick.
* FadSuper:
** Dazzler, the disco-themed singer, debuts in Issue 130, right in the middle of the Dark Phoenix Saga.
** Pipeline, evil minion of the Genoshan government, teleports people via the internet, which was new when he was introduced in the late 80s.
* FaintInShock:
** Played painfully straight in issue 148, when Kitty Pryde (thirteen years old if even that at the time) faints when kidnapped by Caliban in his first appearance. He is much creepier than his later appearances would make him, but ''still...''
** Even more painful in issue 11, where after ''The Stranger'' walks on air and through a wall, someone utters these gentlemanish words:
--->"Someone get a '''doctor!''' Women are faintin' like '''flies''' over here!!"
* FantasticRacism: In addition to the usual examples of normal humans hating mutants (and vice versa), Nightcrawler faces some unusual prejudices in his 1985 miniseries.
** In the first world he visits, everyone mistakes him for a "boggie", a creature that, coincidentally or otherwise, looks very similar to him, has similar powers, and is treated as something of a pest. Because of this, people tend to react to him with fear or treat him with contempt, though his actions eventually force them to change their tune.
** Near the end of the series he runs into Cretacious[[superscript:(sic)]] Sam, a [[FunnyAnimal cowboy t. rex]] who immediately wants to shoot Nightcrawler dead just for being a mammal.
* FastBallSpecial: This series is the TropeNamer. The main combination is Colossus throwing Wolverine, though there are more.
** Beast throws Nightcrawler so he can use the momentum after teleporting to quickly steal Magneto's helmet.
** On the moon during the Dark Phoenix Saga, they take advantage of the lesser gravity, and Wolvie tosses Colossus at Jean, since he knows he'll hesitate when trying to kill her (Colossus ends up hesitating too, pulling his punch).
* FateWorseThanDeath: To get back at the X-Men for his being turned into an infant, which was not their doing anyway, Magneto abducts the X-Men and sticks them in chairs which leave them fully cognizant, but only able to express themselves in baby noises. If Storm had not been an incredibly precocious child and a damn good lockpicker, they would have been stuck that way.
* {{Filler}}: issue 106. Quick, Erik the Red has abducted Lilandra, and D'Ken is about to cause the end of all reality! Time for... a flashback about Professor X's SuperpoweredEvilSide trying to kill the X-Men? Probably caused because issue 107 is largely comprised of a big fight scene. And it does provide a conclusion to the long-running thread of Charles having bad dreams at the end.
* TheFirstSuperheroes: One of the first concepts used for the title way back in the 1960s (when the title debuted) was to refer to mutants as "the children of the atom". This was not without reason, for, at least for that time period, radiation was established to be the MetaOrigin for other superhumans of the Marvel Universe:
** In the very first issue, Xavier explains to Jean Grey his parents worked in the A-Bomb, and the radiation may have caused his mutation. He then states he believes himself to be "the first mutant".
** Beast's backstory in issues #49-53 establishes that his father worked in a nuclear power plant, and, one day, was bombarded with radioactivity. He survived, but his doctor suggested that his genetic material was altered by the event. Thus, "[[TitleDrop a Beast is Born]]".
** In issue #64, Beast surmises that Japanese Sunfire is a mutant himself, since his mother was present at the Hiroshima bombings, and that must have affected her, thus explaining his solar radiation powers.
* FlawExploitation: Issue 106 has Erik the Red make the brainwashed Polaris and Havok attack the passing Fire Lord, ex-herald of Galactus, in order to frame the X-Men. He knows that the HotBlooded Xandarian won't bother to check. Cue the X-Men receiving a painful beat-down, until Jean Grey gets ''mad''.
* ForcedOrgasm: Miranda Leevald / Stacy X is a mutant with the powers of a LivingAphrodisiac able to control {{Pheromones}} to stimulate bodily sensations and functions, such as inducing orgasms or vomiting. For this reason, she was a very popular prostitute before joining the ''X-Men''.
* ForcedTransformation: In issues 190-191, Kulan Gath uses his magic to [[WipeThatSmileOffYourFace remove the mouths]] and warp the arms of Doctor Strange and Selene to prevent them from casting spells against him. He also combines Xavier and Caliban into a single creature and turns the New Mutants and Wasp into more monstrous versions of themselves.
* {{Foreshadowing}}:
** Early on in Claremont's run, hints are dropped as to Storm's claustrophobia (her fondness for being out in the open sky, rather than indoors), but it's not until the All-New X-Men's trip to Ireland that we get the full story on that.
** During the newly minted Phoenix's battle with Fire-Lord, Jean notes that she is feeling unusually aggressive, even wanting to ''kill'' the guy when called away. It is the first hint that her power-up is going to lead to [[ComicBook/TheDarkPhoenixSaga Bad Things]]. Come issue 110, Jean starts ruminating on her increasing powers, and wonders whether it will eventually corrupt her.
** In the lead-up to issue #150, Professor X thinks about how the X-Men haven't heard from Magneto since the All-New team's run-in with him in the low 110s, but that recent weather seems like it must be his work.
* FreakyFridayFlip: Emma Frost swaps bodies with Storm in #151 in order to take the X-Men unawares after a Sentinel attack orchestrated by Sebastian Shaw. With the change in bodies comes a change in powers, as Emma lets lose with destructive weather patterns and Storm struggles to drown out the voices that bombard her newly telepathic mind.
* FreakOut:
** Colossus completely loses it when the team goes into space for the first time, turning into metal and shredding his suit. He's thinking of his brother Mikhail, who supposedly died in a shuttle disaster ("supposedly" because many, many years later, Mikhail would turn up very much alive).
** Storm’s claustrophobia causes her to lose control at several points, with the most dramatic being when she is encased in solid chrome by Doctor Doom and immobilized, leading to her creating a super-storm over the Western Hemisphere in an attempt to free herself. Her appearance after breaking free is so terrifying to behold the X-Men can’t help but compare her to Jean as the Dark Phoenix.
* FragileSpeedster: Nightcrawler, while being the most agile member thanks to his TeleportSpam, is not particularly durable.
* FreakyFridayFlip: Emma Frost forces one on Storm using a personality-swapping gun (actual name the comic uses), so that she can infiltrate the X-Men and "betray" them as Storm. Complications ensue when Sebastian Shaw jumps the gun, and Storm manages to escape. The two characters spend a lot of time trying to come to terms with their new powers, Emma nearly killing herself several times over, and Ororo almost frying Kitty's brain with Emma's powers.
* FusionDance: An involuntary example occurs in issues 190-191, where Kulan Gath uses his dark magic to merge Charles Xavier and Caliban into a single being.
* GeniusLoci: [[Characters/XMenKrakoans Krakoa]], the Living Island. Professor X sends the original team to investigate a newly emerged mutant on a remote island only for them to learn that the island itself was the mutant.
* GiantEnemyCrab: The team fights these on Krakoa. Since the Living Island seems to have some level of reality warping abilities within its personal biome it’s more than likely that it’s the one creating them.
* GlassCannon:
** Cyclops, although by no means fragile, is not particularly durable either. But his beams pack quite a punch.
** Similarly, Jean, whose telekinesis and telepathy are incredibly powerful, but she's even ''less'' durable than Scott.
** As is the case with Jean, Storm, who can shoot friggin ''lightning'' at her enemies and ''create hurricanes'', but is pretty vulnerable otherwise.
** When you get right down to it, pretty much any X-Man whose power doesn't involve some kind of super-toughness or shielding is this, being ordinary humans other than the specifics of their power.
* AGlassInTheHand: In issue #161, Lilandra learns from Gladiator that Reed Richards has saved the life of a dying Galactus, and crushes the glass she has in her hand at the moment. (Presumably Shi'ar medical tech could fix up the fact she probably cut her hand to chunks).
* GoodSmokingEvilSmoking: In case her general attitude, smugness, sinister grinning and total lack of empathy wasn't kind of a hint already, Emma Frost tended to smoke in her villain days, out of an evil cigarette holder, including when she had hijacked Ororo's body.
* GoneHorriblyRight: In "Rise and Fall of the Shi'ar Empire", the anti-Lilandra faction of the Shi'ar manipulate things so Vulcan will free Deathbird, hoping to have her supplant her sister. Events change so that Vulcan revives D'Ken from his years-long coma, which they regard as even better. Then Vulcan kills D'Ken and, having married Deathbird, makes himself emperor. He proves to be not much saner than D'Ken, management wise.
* GotMeDoingIt: In his 1985 miniseries, Nightcrawler is repeatedly mistaken for something called a "boggie", much to his increasing frustration. Then he finds himself needing to [[ItMakesSenseInContext distract a gunslinging dinosaur]] by telling it that he's not a mammal, and when it asks what he is, he blurts out the first thing that comes to mind--which, of course, is boggie. He immediately feels like kicking himself:
-->'''Nightcrawler:''' A boggie!? I must've finally gone 'round the bend! I actually told this overgrown lizard I was a boggie! ''GET ME OUT OF THIS MADHOUSE!''
* GrievousHarmWithABody:
** During an argument, Wolverine clobbers Juggernaut with Colossus.
** During the first fight with the Shi'ar Imperial Guard, a just-singed Logan grabs Oracle as she's laughing at him, and batters Starbolt with her.
** Colossus and Wolverene's trademark FastballSpecial move is a ranged version of this.
* GroupReactsIndividually: #500: A human art collector named Guy [=DeMondue=] organizes an art exhibit with mutant-hunting sentinels. The X-Men are informed of this and react ''badly'' to it: Beast and Angel (two of the original X-Men) remark on their lethality to mutants, while Emma Frost says it is in bad taste, for a ''completely'' different reason:
-->'''Angel:''' Sadie, come on! Twenty-foot-tall '''death machines--'''
-->'''Beast:''' Genocidal robots no more artful than an A-Bomb--
-->'''Emma Frost:''' Banal, predictable "shock schlock" that was passé in New York ten years ago--
-->'''Wolverine:''' Hell with this.
* GuestStarPartyMember:
** Sunfire and the previous X-Men team barring Cyclops in ''Giant Sized X-Men'' #1.
** Spider-Man in Issue 123.
** Doctor Strange accompanies the team on a journey to “Hell” to save Nightcrawler’s soul (later revealed to be an illusion created by Margali Szardos) in Annual #4.
** The ComicBook/InvisibleWoman joins the team to help save the rest of the ComicBook/FantasticFour when they are kidnapped by the Badoon in Annual #5.
** ComicBook/CarolDanvers accompanies the team for so long following her de-powering that she practically becomes a member through ''ComicBook/TheBroodSaga'' and fully intends to join the team as Binary following the events of that story. [[spoiler:If it weren’t for Xavier allowing her earlier attacker Rogue to join the team as well, Carol might have stuck around for a long time.]]
* GuileHero: Cyclops largely grows from the straight-laced “Execute Attack Pattern Alpha!” style leader of the Lee-Kirby years into a MagnificentBastard capable of thinking out dozens of plans simultaneously while on the run in the Claremont era. Probably best exemplified during the team’s second fight with Dark Phoenix [[spoiler:actually one of Mastermind’s illusions mapping the Dark Phoenix’ form onto Scott’s body.]] With his teammates fighting against him Scott tricks Kitty into phasing him into the Danger Room, where he hass programmed a Savage Land scenario on the fly to keep them all off balance and give him time to find the perpetrator of the attack.
* HeadbuttingHeroes: Wolverine and Cyclops are a pretty well-known example, with Wolvie hating Cyke for his cautiousness and Cyclops hating Wolverine for not following orders and his lone wolf tendencies. They got better, but it never really faded completely.
* HeelFaceDoorSlam: In the early 90s, after a long while of being good-ish, and trying to atone for his past deeds, Magneto comes to the conclusion that he is not Xavier and never will be. He decides to prove it by killing Zaladane. The out-of-universe reason is that artists started having more clout than the writers, and the artist on X-Men wanted Magneto as a bad guy again. Of course, it turned out that door was a little jammed...
* HeelFaceTurn:
** Rogue, who started out as a member of The Brotherhood before joining the X-Men to help with her powers.
** Magneto becomes a full-fledged member of the team during Claremont’s run, with Xavier even appointing him as head of the school.
* HeroicBSOD: Storm, following her Depowering. Forge helped her get through it... though she did not take it well when she found out he was responsible for it in the first place.
* HeroicSacrifice:
** Jean ''thought'' she was pulling one when she decides that, with her TK, she can keep out lethal radiation long enough to pilot a shuttle containing the X-Men. However, the Phoenix decided differently.
** The Phoenix itself (still masquerading as Jean) does this on the Moon when it realizes that the Dark Phoenix will come back eventually no matter what. Its death (albeit temporary) leads to the real Jean's eventual resurrection.
* HeroWithBadPublicity: Right there in the opening titles, "sworn to protect a world that hates and fears them." Most of the X-Men's major victories tend to be things where there are no witnesses, while their public fights tend to be destructive. Not helping is the time one of their fights accidentally killed Senator Robert Kelly's wife.
* HideYourGays: Due to the time they were written in, Claremont issues could never ''say'' that Mystique and Destiny were lovers. But there were the occasional great big flashing signs hinting at it.
* HoistByTheirOwnPetard: The first time Xavier's evil side appears, it attacks the All-New team with simulations of the Original Five. When Xavier shows up to end things, he has the [=05=] projections beat up his evil side.
* HopelessSuitor: Early on, Colossus has a massive boy-crush on Storm. She is very much aware of it, but doesn't reciprocate.
* HypocriticalHeartwarming: The first hint that Wolverine is not 100% a dick is during the team's first fight with a demon. It hurts Kurt, prompting Logan to declare that no-one hurts the elf. This would be the same Nightcrawler who Logan tried to murder for ''laughing'' at him earlier that very day.
* IAmTheNoun: Lilandra tries to stop a fight between the Shi'ar Imperial Guard and the X-Men by declaring "'''I''' am the Empire!" Then Chancellor Araki steps in to inform her that, what with that whole "treason" thing, she isn't.
* ICannotSelfTerminate: When [[spoiler:Rachel van Helsing]] is turned into a vampire by Dracula in ''Uncanny X-Men Annual'' #6, she asks Wolverine to [[MercyKill kill her]] with a wooden stake.
* IHaveYourWife: Miss Locke forces the X-Men to try and rescue Arcade by abducting their friends and family.
* IKnowYoureInThereSomewhereFight: Kitty to Storm when Storm was bitten by Dracula.
* ImaginedInnuendo: Under attack by some brainwashed hippies (it's a whole thing), Scott warns Emma about her flank. Emma tells him that he had better not mean what she thinks it means, or he is not getting any "flank" that evening.
* ImprovisedCross:
** In one eighties issue, Nightcrawler and Wolverine are fighting Dracula. Wolverine crosses his claws to make a cross and Dracula tells him that in order for that to work on him you have to believe. Nightcrawler holds up two pieces of wood in a cross-shape and tells Dracula "I believe!" and Dracula recoils. Look at it [[http://www.supermegamonkey.net/chronocomic/entries/scans10/UX159_Cross2.jpg here]].
** In ''Uncanny X-Men Annual'' #6, which is a continuation to the events above, Rachel Van Helsing keeps Dracula at bay with two candlesticks forming a cross. Since she has been recently turned into a vampire, it burns her as well.
* InnerMonologue: During Chris Claremont's run, characters had a tendency to do this.
* InnocentFanserviceGirl: Storm, before she got the hang of American sensitivities. Basically she did not mind appearing naked or half-naked to her teammates, as she uses this style while living in Kenya.
* InsaneTrollLogic: Hijack pretty much ran on this when it came to using his phone.
* InteractiveNarrator: The narrator, who is kind of a [[{{Jerkass}} condescending dick]], sometimes taunts the characters.
-->'''[[{{Narrator}} Omniscient Narrator]]''': You and the X-Men had saved the '''world''' from a '''[[TheEndOfTheWorldAsWeKnowIt nuclear holocaust]]''', but you '''[[HeroicSacrifice lost]] [[SacrificialLamb a man]]''' to do it... and '''try''' as you might, you can't '''balance''' those scales in your mind '''or''' in your heart... '''can''' you, Cyclops?\\
'''Cyclops:''' No.\\
'''Narrator: Can you?'''\\
'''Cyclops: No!'''\\
'''Narrator: [[RuleOfThree CAN YOU]]?'''\\
'''Cyclops: [[BigNo NO]]!!'''
* IntimateLotionApplication: In Issue #353, the X-Men go to hang out in a lake and Maggot offers a bikini-clad Storm if she'd like him to rub oil on her back for her sake, but she declines, pointing out she's immune to getting burned. Then he asks if she would still let him run oil on her anyway for ''his'' sake, and gets shot down again.
* IOweYouMyLife: Magneto strong-arms Quicksilver and the Scarlet Witch into joining the Brotherhood of Evil Mutants after saving them from an angry mob. They leave the first chance they get.
* {{Jerkass}}: Angus [=McWhirter=], a temperamental Scottish boat owner the All-New team tries to procure transport to Muir Island from. He refuses to give them a boat, paid for in Moira's name, and refuses to give the money back. So Colossus hangs him from a pipe and the X-Men take his boat anyway. Then, when Magneto destroys it, Mr [=McWhirter=] decides the best response is to go to Muir Island and blow it up, not caring whether anyone innocent will be hurt (in fact thinking "so much the better").
* JerkassBall: Professor X had the occasional tendency to cling to it. The infamous "Professor X is a JERK!" incident being a stand-out example.
* JerkassHasAPoint: The beginning of issue 106 has Wolverine, pre-CharacterDevelopment, telling Cyclops to lay off on unfairly comparing the new team to the original X-Men. Banshee points out that as unpleasant as Wolverine is, he is right. A fact Scott concedes.
* JerkWithAHeartOfGold:
** Early Wolverine was, put succinctly, a raging asshole, often drawing his claws on his teammates for minor offences. He once tried to kill Colossus ''for saving his life'', for God's sake. It takes some time (in and out of universe) for him to lighten up.
** Sunfire, being a proud, racist nationalist, started off as an antagonist to the X-Men. He was later persuaded to join briefly by Charles, then almost immediately quit, then came back. Then he quit again once everything was over. However, when Logan first meets his cousin Mariko, she notes that he often spoke of the X-Men with respect.
* KidFromTheFuture: Rachel Summers/Grey debuted here. She is the daughter of Scott Summers and Jean Grey from a dystopian future, having time-traveled into this era.
* KidHero: The original team were all teenagers when Professor Xavier recruited them. Even among the All-New, All-Different team, Colossus was 17 when he joined and Kitty was [[InsistentTerminology thirteen-and-a-half]]. It is with the creation of the first spin-off title ''ComicBook/NewMutants'' that Xavier starts separating recruits between the adult and teenage team, though there would be exceptions such as the later introduction of Jubilee.
* KillerRobot: The Sentinels, not to mention the much more advanced model Nimrod.
* LanguageBarrier: In issues 190 and 191, Spider-Man and Warlock are the only people in the transformed Manhattan who can still speak English. Everyone else is speaking whatever Hyborian-era tongue Kulan Gath's spell has forced upon them, making it impossible for Spidey to understand them or be understood.
* LargeHam: Even in a WorldOfHam, Storm stands out for being the hammiest. ''Especially'' during Claremont's run.
* LaserGuidedAmnesia:
** In the Lee / Kirby days, Professor X tended to throw this around willy-nilly. Villain with a dangerous power? Zap! Hero summoned to your secret base who can't keep a secret? Zap! Loved ones who might ask where you've gone? Sorry, Beast, ''Zap!''
** It turns out that, when Emma and Namor confronted Sebastian Shaw about his building Sentinels, Selene made sure Emma forgot about the entire event. She remembered when she pieced her memory back together after fighting the Phoenix.
* LetsYouAndHimFight:
** The team's attempts to stop Lucifer (the alien warlord) aren't helped by the Avengers getting involved.
** The X-Men return to Earth to stop the Brood embryo near-to-term within Xavier and run into the (from their perspective) previously unseen New Mutants living at the mansion. Both groups immediately devolve into a fight, with the New Mutants putting up a bit of a fight before being overwhelmed by the much more experienced X-Men.
* LittleBlackDress: Storm dons one for a formal do at Cassidy Keep. Nightcrawler is understandably awed.
* LoveTriangle:
** When Jean shows up for the first time all of the other guys -- except for Bobby -- immediately start drooling over her. Hank settles into an easy friendship with her soon after leaving Scott and Warren to vie for Jean's affections for a good part of the Silver Age. Warren eventually realizes that he and Jean are BetterAsFriends and Scott and Jean become the one true X-couple from thereon out with [[ComicBook/{{Wolverine}} no one]] [[ComicBook/EmmaFrost ever showing up]] [[BlatantLies to try and split them up]].
** Iceman, Havok and Lorna Dane, which eventually seemed to conclude with Havok ending up with Lorna.
** The famous Cyclops-Jean-Wolverine triangle. Jean generally prefers good-if-utterly-crap at expressing his feelings Scott, but there's ''[[{{Understatement}} some]]'' attraction to Logan in there.
* LukeIAmYourFather: Corsair reveals to Scott that he is his father on their second meeting.
* LukeYouAreMyFather: In the 140s, Siryn, who'd tussled with Spider-Woman in her own title, pops over to the X-Mansion to tell Banshee some interesting facts re; his long-dead wife and this young Irish woman who's shown up to see him.
* MacGuffinGuardian: The M'Kraan Crystal is guarded by the tiny but powerful Jahf. Should anyone somehow defeat him, he is replaced by the much larger and every bit as hard to kill Modt, who assures the X-Men that if he goes down, someone even more powerful will replace him, and so on until their opponent dies (or flees).
* MeaningfulEcho: When Angel quits the team in disgust as Wolverine's... everything, Storm and the Professor have a chat about why they keep the man around, with Storm noting it's because of his capacity to do good. Many, many issues later, when the rest of the X-Men are about to quit in protest of Rogue joining the team, the Professor cites that speech back at her.
* MegatonPunch: Carol Danvers does not take running into Rogue after their first encounter, which ended with Rogue's foster mom very nearly killing her among other things, very well. She sends Rogue flying out through the roof.
* AMindIsATerribleThingToRead: During the fight with Kierrok the Damned, Professor X tries reading his mind. This very quickly turns out to be a mistake.
* MissingDad: Cyclops' dad, Corsair, shows up when the X-Men first encounter the Shi'ar, and after a quick mind-scan, Jean reveals she knows who he is.
* TheMole: [[spoiler:Cyclops]] during the X-Men's first conflict with the Brood, as it is revealed [[spoiler:that under his visor, his transformation was happening]].
* MyMasterRightOrWrong: Gladiator of the Imperial Guard operates on this, and JustFollowingOrders. To a lesser extend, most of the Guard is ready to obey whoever sits on the Shi'ar throne.
* NarratingTheObvious: One of Claremont's failings is that he cannot let a scene stand on its own, the characters ''have'' to narrate their every action, no matter how freaking obvious it is.
* NegatedMomentOfAwesome: Subverted in issue 191. Spider-Man, having been captured and tortured by Kulan Gath, manages to break free of his restraints as the Avengers and X-Men launch an attack on the sorcerer's throne room. He urges everyone to grab Kulan Gath's amulet, the source of the wizard's power, and is promptly struck down by Gath, who mockingly reminds Spider-Man that none of the assembled heroes can understand him. But Warlock ''does'' understand, and after conveying this information to Storm, the two of them manage to surprise Kulan Gath and rip the amulet away from him, ensuring his downfall.
* NewPowersAsThePlotDemands:
** Magneto. Ye Gods, ''Magneto''. Magnetism apparently allows him to fly, mind-control people, knock folk unconscious, protect himself from convection, predict where Nightcrawler will teleport... and, on occasion, he will use it to manipulate metal.
** Jean's transformation into the Phoenix is all over this. Previously limited to telekinesis and telepathy, Jean suddenly has the power to; transform her clothing, fly, shoot fire, throw down with Heralds of Galactus, open stargates... oh, and surviving being killed by unfiltered and ludicrously lethal levels of radiation. A little beyond your average telekinetic, that.
* NewSeasonNewName:
** Originally launched as ''The X-Men'' in 1963, it switched to simply ''X-Men'' on all covers from issue #50 (1968), adding ''The Strangest Teens of All'' as a subtitle from #60.
** With #94 and the new team relaunch, it became ''The All-New All-Different X-Men''.
** With #114 it became ''The Uncanny X-Men''
** With #394 it became simply ''Uncanny X-Men'', a title which remained until the final issue (#544) in 2011.
* NiceJobFixingItVillain: Emperor D'Ken, as part of Deathbird's wedding, has Charles thrown into the M'Krann Crystal, to drive him mad the same way it did D'Ken. All it does is restore Charles' telepathy, which he had lost after M-Day.
* NoHoldsBarredBeatdown: Emma Frost deals out two brutal ones to Lady Mastermind during the "Sisterhood" story arc. In consecutive issues, no less.
* NoMisterBondIExpectYouToDine: Doom invites Storm into his castle for dinner after she threatens him... and continues the dinner even though he knows that she is distracting him.
* NomDeMom: Rachel Summers, after her return, changes her name to Rachel Grey thanks to Scott going out with Emma Frost at the time.
* NuclearMutant: Early on, the explanation for the sudden appearance of mutants was the development of the atomic bomb, hence the team's nickname "Children of the Atom". Despite this, most of them do not owe their powers to exposure to nuclear radiation. Sunfire does, [[RadiationInducedSuperpowers because his family were at Hiroshima.]]
* OddReactionOut: #500: A human art collector named Guy [=DeMondue=] organizes an art exhibit with mutant-hunting sentinels. The X-Men are informed of this and react ''badly'' to it: Beast and Angel (two of the original X-Men) remark on their lethality to mutants, while Emma Frost says it is in bad taste, for a ''completely'' different reason, and Wolverine doesn't offer a specific dislike:
-->'''Angel:''' Sadie, come on! Twenty-foot-tall '''death machines--'''
-->'''Beast:''' Genocidal robots no more artful than an A-Bomb--
-->'''Emma Frost:''' Banal, predictable "shock schlock" that was passé in New York ten years ago--\\
'''Wolverine:''' Hell with this.
* OhCrap: One issue ends with Kitty's "muggle" best friend Doug Ramsay telling her, shortly after he helped her hack some Hellfire Club stuff, that he has just gotten an offer to join this exclusive school... in ''Massachusetts''. Kitty is appropriately terrified for her oblivious friend (and yes, it's an Emma Frost plot).
* OnlyFriend:
** Black Tom Cassidy is this to Juggernaut. They are rarely seen hanging out with others.
** Also, Unus the Untouchable to Blob. Already the 1960s appearances of the Blob, established that he was a loner. His attempts to bond with others were failures, but he got along well with Unus.
* OrphanageOfFear: Cyclops grew up in one, which was run by a crazed Victorian scientist who did everything he could to make sure it was one for Scott, including brainwashing (or just flat-out killing) anyone who showed him a moment's kindness.
* PintsizedPowerhouse: Jahf, First Guardian of the M'Kraan Crystal. He is barely three feet tall, and can hit hard enough to send a man with an adamantium skeleton into ''orbit'' with just one punch.
* ThePiratesWhoDontDoAnything: The Xavier Institute is supposed to be a school, but an awful lot of the time you won't see the X-Men doing any schoolwork, or teaching anyone. Of course, the fact the school was a cover for teaching them to learn how to protect a world that hates and fears them has something to do with this. It wasn't up until Grant Morrison's ''New X-Men'' that the school had a population large enough for them to ''have'' to teach.
* PoirotSpeak: Claremont loved him some accents. Naturally, this came up a lot with Nightcrawler (German), Colossus (Russian), and Gambit (French-Cajun) as just some examples.
* PlaceOfPower: Kulan Gath notes that Charles Xavier and Doctor Strange would be more than a match for him under normal circumstances. Unfortunately for them, his master spell has warped Manhattan into a Hyborian version of itself, where their powers are weakened and Gath's black magic reigns supreme.
* ProgressivelyPrettier:
** Rachel Grey, what with having grown up in a dystopian internment camp. Logan at one point compares her to a Holocaust survivor (Logan knowing whereof he speaks). After she got put on a bus and reappeared in ''Excalibur'', she had suddenly filled out, gained a few feet, and developed a fondness for leather.
** Rogue started off as a skinny teenager. [[BlatantLies Mysteriously]], she starts looking like a supermodel around the time Jim Lee started working on the title.
** When he first appeared, Banshee was drawn as looking like an offensive 19th century Irish stereotype. When he reappears in ''Giant-Sized X-Men'', he suddenly looks a lot hunkier.
** Nightcrawler. In his earliest appearances, he has harsh facial features, mixed with the blue fur, yellow eyes and pointed teeth. After a while, his features started developing so he looked... well, hot.
* PsychoRangers: The X-Sentinels to the original X-Men. They are Sentinels with the same powers and abilities.
* PurpleProse: Since the series debuted in the Silver Age, this is to be expected, but Chris Claremont's run was ''infamous'' for this, describing even the most simple actions with narration boxes, even through into the beginning of the Dark Age.
* PunctuatedForEmphasis: Magneto makes his reappearance with a suitably dramatic entrance.
-->'''''I. AM. MAGNETO!'''''
* ThePurge:
** The Mutant Massacre, where the Marauders exterminate a whole heck of a lot of the Morlocks.
** Shortly after ''House of M'', the Shi'ar wipe out ''all'' of Jean Grey's family, out of manic fear of the Phoenix.
* PutOnABus: Quite a few characters over the years, especially during Chris Claremont's long run.
** Beast left the team first, graduating from the school, and going off to his own adventures in other titles, before a decades long sting with some guys called "the Avengers".
** The entire original group of X-Men, save Cyclops, leave after Giant-Sized X-Men. Jean, Havok and Lorna Dane return soon after, but Iceman and Angel take a while longer.
** Banshee, who left after losing his powers after straining them to save all of Japan from sinking into the ocean.
** Cyclops leaves in #138 (the issue following the ''Dark Phoenix Saga'') and returns after helping the team defeat Magneto in #150.
** Wolverine, during his mini-series and engagement to Mariko. After Mastermind caused her to break said engagment off, he rejoined the team.
** Cyclops, who lost leadership to Storm, despite her being without powers at the time, and decided to leave again to spend more time with his family.
** Nightcrawler and Shadowcat, both of whom were horribly injured during the Mutant Massacre, and woke to find the X-Men apparently dead, leading to them founding Excalibur.
** Sage leaves after ''Decimation'', getting transferred over to ''New Excalibur''.
** Havok, Polaris, and Rachel remain in Shi'ar space at the end of ''Rise and Fall of the Shi'ar Empire'', to try and stop Vulcan. They remain up there until 2011.
* RapidAging: Magneto was de-aged to a baby in a storyline of the Defenders. Once the X-Men returned, he was aged back up into his regular age by Eric the Red.
* ReallyGetsAround: Funny enough, ''Charles'' becomes this during the Bronze Age. We are introduced to two major flames of his from the past in the form of [[Characters/XMenMutants Moira MacTaggert]] and Gabrielle Haller, mother of Xavier's son David, aka ComicBook/{{Legion|MarvelComics}}. And then there's Shi'ar Empress Lilandra, who becomes his recurring flame for over a decade after a brief courtship at the beginning of ''ComicBook/TheDarkPhoenixSaga''.
* ReedRichardsIsUseless: Early Magneto is a bona-fide genius who makes Reed look like a chump. He is able to do things like turn a school into a genetics laboratory far beyond the reach of '60s science, make underground bases with shielding able to keep out lava, and advanced robotics, and a freaking asteroid base. He never once uses this for anything over than his own petty drives (the whole "protecting mutantkind" thing came later).
* ResignationsNotAccepted: Wolverine is convinced to join the X-Men by Professor X, and tells Department H where they can stick it. A few years later, his old buddy Jim Hudson (later known as Guardian) comes to bring him back by force. When that doesn't work, he returns with Alpha Flight.
* ResurrectedForAJob: Betsy Braddock's revival after her bout of death in ''X-Treme X-Men'', as her brother Jamie reveals. He did so that she could defeat the First Forsaken.
* {{Retcon}}:
** The story of Charles' encounter with the Shadow King is an example of a seamless retcon, fitting in neatly to established continuity and building on previous stories.
** Magneto turning out to having once been friends with Charles, meanwhile, not quite so much. This came after several decades of stories with the two characters, with no hint of a personal relationship. But it does put their fight, and Magneto's beef with the X-Men in a different and more complex light. So no-one's about to complain.
** Almost everything involving Jean and her connection to the Phoenix Force, including whether it was her or the Phoenix itself that interacted with the X-Men during ''ComicBook/TheDarkPhoenixSaga''. This retcon was a major cause behind the splintering relationship between Claremont and Marvel execs during the late 80s and early 90s.
** Pyro's early issues state, quite clearly and repeatedly, that he is most distinctly British, and in case you miss that, everyone else calls him British and he uses various cockney Britishisms. Later on, he just becomes Australian, and never looks back.
** ''Deadly Genesis'' retcons Giant-Sized X-Men, claiming there was another team Charles sent to the island between the original team and the All-New X-Men, and that Krakoa was not actually sentient at all.
* RidiculouslyHumanRobot: Stephen Lang ([[ComicBook/AntMan no relation]]) managed to build X-Sentinels, who managed to imitate the powers of the original seven X-Men expertly, including Jean and the Professor's telepathy. Somehow. It took Logan's nose to figure them out.
* RiddleForTheAges: The first time we learn Logan's name, it's from a leprechaun. Yes. [[NotMakingThisUpDisclaimer A leprechaun.]] How exactly a leprechaun knows Logan's name goes entirely unrevealed.
* RoaringRampageOfRevenge: Cyke, when he thought Jean was killed by Stephen Lang. She ''just'' manages to stop him from killing the guy.
* RunningGag:
** In the early Claremont issues, every time the X-Men go near a vehicle, it gets trashed, be it car, jet, space shuttle, hovercraft. They set foot in it, it goes "boom". Eventually, Nightcrawler starts cracking wise about it.
** As seen above in EarlyInstallmentWeirdness, Claremont would come up with new wrinkles to Wolverine’s character that he would casually drop in conversation such as his adamantium skeleton, healing factor powers and even his ''real name''. Naturally, one of his teammates would ask why he never told them about (insert new revelation here), with this always being the response: "You never asked, bub."
** Kitty and her impractical or flat-out ridiculous outfits.
* SacrificialLion: Thunderbird for the All New, All Different X-Men, dying on their second mission. Unfortunately, it's also a SenselessSacrifice.
* SecretlyEarmarkedForGreatness: In issue #300 (first story), Xavier remembers a date he had with Moira where they talked about the founding of his school. Xavier showed Moira pictures of Jean Grey, Scott Summers, Hank [=McCoy=], Warren Worthington III and Bobby Drake (who will become his [[Characters/{{XMenTheOriginalTeam}} first generation of students]]). Moira then commented on another set of images showing a African woman (Storm), a blue-furred acrobat (Nightcrawler) and a towering, burly man (Colossus), to which Xavier replied that he considered the latter three potential recruits for "[[Recap/{{XMenChrisClaremontGiantSizeXMenVol11}} the next generation of X-Men]]".
* SenselessSacrifice: Thunderbird's death is not only [[WeHardlyKnewYe early]], it was also largely pointless. He kills himself by crashing the jet villain Count Nefaria is trying to escape in while ranting about his Apache pride -- ignoring the constant warnings from Xavier to stop before he kills himself, or the pleading from Banshee, who not only could have carried him away to safety but ''easily'' stopped the jet with little trouble. Did we mention Nefaria also survived?
* SeriesFauxnale: Issues #65 and #66 serve as one to the original incarnation of the team:
** Professor Xavier is revealed to have survived his "death" from issue #42, and trains the X-Men to withstand a Z'Nox invasion. During the climax of the issue, Xavier uses his powers to connect with every human mind on the planet and redirects the connection to Marvel Girl, who links with Havok, who uses his powers to energize Cyclops, while Iceman cools them off from the heat the energy provides. The invasion is averted, but the strain of such a display of his powers weakens Xavier.
** In the next issue, the original five X-Men seek the help of Dr. Banner and find a device that can restore Xavier's mental state. The Professor is saved, everyone smiles, and an ending caption narrates that "[[AndTheAdventureContinues and they fought]] happily [[TheEndOrIsIt ever after...??]]"
* SetRightWhatOnceWentWrong: In the classic "ComicBook/DaysOfFuturePast" storyline, Kitty Pryde travels back into her old body to prevent the Sentinels' rise to power.
* SexySurfacingShot: An early issue had Storm SkinnyDipping at the mansion pool, when the rest of team catches her as she is coming out of the pool. She [InnocentFanserviceGirl innocently asks]] why are they are all [[EatingTheEyeCandy staring]].
* ShamingTheMob: When Rogue tries to join the X-Men, they swear then and there to quit. Professor X promptly reminds Storm that she once stood by Wolverine when he was at his worst, so why should Rogue not be given a chance? This more or less convinces them.
* SherlockScan: Taken to the point of parody with Spider-Man, when he guest stars. He is able to recognize a brainwashed Cannonball, in the middle of a pitched fight where everyone else is looking different thanks to a spot of magic-induced reality-warping (long story), after a second's glimpse by... Sam's distinctive ears.
* ShipTease:
** Claremont's second run has a lot of this between Bishop and Val Cooper. Then in the final issues, the other X-Men finally comment on how chummy they have gotten, and Bishop suddenly [[SheIsNotMyGirlfriend explodes at them about how their relationship is strictly professional.]]
** Emma and Namor. She is half of why he even aligned himself with the X-Men.
* ShoutOut:
** Nightcrawler receives an image inducer to hide his appearance in public and remain anonymous, which he tends to render useless by choosing some A-List Hollywood celebrity. At one point he shifts through several appearances such as Creator/ClarkGable and Creator/GrouchoMarx before settling on his usual form of Creator/ErrolFlynn.
** Our first look at the Shi'ar is one great big ''Series/StarTrekTheOriginalSeries'' homage, right down to the ship's bridge layout, the crew's uniforms... they even have a Prime Directive.
** Kitty, being a massive ''Star Wars'' nerd, tries doing an homage to ''The Empire Strikes Back'' at one point, namely the scene of Yoda lifting the X-Wing (X-Wing, X-Jet, geddit?). Kitty ends up teasing the X-Men by saying she had gained new telekinetic powers that would allow her to retrieve the Blackbird from the ocean floor where it crashed. The X-Men are suitably impressed, until they see Colossus carrying the plane out of the water, at which point they realize they've been had.
** Kitty Pryde uses a Shi'ar clothing machine to first give herself a version of Mary Marvel's outfit, then... [[Franchise/StarWars Darth Vader]]. Another issue shows her reading an issue of Marvel's contemporary ''Star Wars'' comic.
** In one issue where Carol Danvers is hanging around, she wears a red shirt with a stylized lightning bolt on it. Or, in other words, the insignia of the ''original'' Captain Marvel.
** Watching the wedding of Vulcan and Deathbird, Warpath compares it to the marriage of Prince Charles and Lady Diana (presumably in terms of pomp and circumstances, not in terms of how the couple feel about one another).
* ShutUpHannibal: Jean tells Wolverine to shut up when he acts like a dick to try to stop her from piloting a shuttle through a solar flare (she says her TK will protect her).
* SignatureLine:
-->'''Charles Xavier:''' ''To me, my X-Men!''
-->'''Wolverine:''' ''I'm the best there is at what I do, and what I do isn't very nice.''
** Several during ComicBook/TheDarkPhoenixSaga:
-->'''The Dark Phoenix:''' ''I am fire! And life incarnate! Now and forever! I! Am! PHOENIX!!''
-->'''Wolverine:''' ''Okay, suckers--you've taken yer best shot! Now It's My Turn!''
-->''Welcome to the X-Men (insert new member of the team here), hope you survive the experience!''
** For Kitty:
-->'''Kitty:''' ''Professor Xavier is a jerk!''
* SignatureMove: The FastballSpecial.
* SignatureScent: Characters always state that the remnants of Nightcrawler's teleportation cloud smells strongly of brimstone. Meanwhile, up until the first ''X-Men'' movie came out, Wolverine was mentioned to smell ''bad''.
* SignatureSoundEffect:
** "SNIKT!" for Wolverine popping his adamantium claws.
** "BAMF!" for Nightcrawler teleporting in a cloud of smoke.
** The lesser-used "ZARK!" whenever Cyclops fires his optic blast.
* SkewedPriorities: During the X-Men's first encounter with D'Ken, the scene briefly cuts back to Earth, where Dr. Corbeau is bickering with President Jimmy Carter (whose focus groups don't believe Corbeau), and Reed Richards, who chides Peter for being "flippant" when he yells at everyone that reality is breaking down. He is not being flippant in the slightest.
* TheSmurfettePrinciple: With all the lineup changes over the years, there were a few rosters with only one female member:
** ComicBook/JeanGrey was the only female member from issues #1 to #59 (September, 1963-August, 1969). Then supporting character Lorna Dane (Polaris) joined the team.
** ComicBook/{{Storm|MarvelComics}} was the only female member in issues #95 to #96 (October-December, 1975), after the resignations of both Jean Grey and Polaris. Then Jean rejoined the team.
** The X-Men disbanded in 1989. The issues continued following former X-Men and their associates.
*** Jubilee was the only female protagonist in issue #252 (November, 1989).
*** ComicBook/{{Psylocke}} was the only female protagonist in issue #256 (December, 1989).
*** ComicBook/{{Dazzler}} was the only female protagonist in issue #260 (April, 1990).
*** Storm was the only female protagonist in issues #265 to #267 (August-September, 1990). She is also the only female protagonist in issue #270 (November, 1990).
** Rogue was the only female member in issues #343 to #349 (April-November, 1997). She does not appear in issue #346 (August, 1997). Psylocke appears in her own subplot in issues #348-349 (October-November, 1997) but does not interact with the team. Then Psylocke rejoins the team.
** The X-Men briefly disbanded in 1999. The issues continued following a duo of former X-Men. Marrow was the only female protagonist in issues #373 to #374(October-November, 1999). Then the team reformed with Rogue, [[ComicBook/KittyPryde Shadowcat]], and Storm joining the ranks.
** Jean Grey was the only female member in issue #394 (July, 2001). Then the title started featuring an all-male roster.
** Stacy X was the only female member in issues #399 to #409 (December, 2001- September, 2002). Then M joined the team. Stacy was also the only female member in issues #414 (December, 2002) and #416 (February, 2003), following the departure of M. Then supporting character Husk joined the team.
** Husk was the only female member in issue #435 (February, 2004). Followed by a spotlight episode for a male member of the team.
** Polaris was the only female member in issue #443 (June, 2004). Then title then started featuring a new roster, with Marvel Girl/Rachel Grey, Sage, and Storm.
** ComicBook/EmmaFrost was the only female member in issue #492 (January, 2008). Then Storm returned. Emma was also the only female member in issues #494 to #495 (March-April, 2008) and #497 (June, 2008). Hepzibah appeared in #496 (May, 2008) and in subsequent issues.
* {{Soaperizing}}: Exemplified during Claremont's run.
* SpaceOpera: The title becomes this with the ''Phoenix Saga'' and ''The Dark Phoenix Saga'', where the Shi'Ar Empire and the Starjammers are introduced. The franchise has never looked back since.
* SpannerInTheWorks: During the ''House of M'' crossover, Roma and Saturyne prepare to nuke the main reality to stop Wanda's reality warping spreading. Up pops Jamie Braddock to stop them, before disappearing again.
* SpinOff: As Claremont added more and more characters (and the franchise exploded in popularity) a number of these popped up:
** ''ComicBook/NewMutants'', detailing the adventures of Xavier’s second group of students (the All-New, All-Different team were adults when they joined and did not fit the “teen superhero” aesthetic of the first team). This series would eventually be rebooted as ''ComicBook/XForce''.
** ''ComicBook/XFactor'', which saw the original five X-Men (Cyclops, Jean Grey, Beast, Iceman and Angel) forming a new team that pretended to be mutant hunters so they could rescue young mutants on the run. The original members would all rejoin the team after the ''Muir Island Saga'' with Havok, Polaris, Multiple Man and others forming a new X-Factor as a group of government sponsored superheroes.
** ''ComicBook/{{Excalibur}}'', a combination of X-characters (Nightcrawler, Kitty Pryde and Rachel Summers) and Marvel UK characters (Captain Britain and Meggan) going on wacky adventures across the Multiverse.
** ''ComicBook/{{Dazzler}}'' would spin-off into her own series instead of joining the team after ''ComicBook/TheDarkPhoenixSaga''. Due to the deal worked out by Marvel editorial her first appearances in ''Uncanny X-Men'' were more of a BackdoorPilot than anything. She would join the X-Men proper after the cancellation of her series.
** ''ComicBook/{{Wolverine}}'', being the BreakoutCharacter would receive his own [[ComicBook/Wolverine1982 limited series]] in 1982 written by Claremont with art by Frank Miller and later star in a LongRunner solo series as he continued to eclipse every other mutant in the Marvel Universe.
* SpottingTheThread: An issue begins with some punk kids in New York getting sliced up by ''someone'' with adamantium claws. While in the morgue, the coroner notes to Logan that he can't have done it - for one, there's only two claw marks, and second, they're closer together than Logan's. The culprit is X-23.
* StealthHiBye: In issue #322, Juggernaut falls from the sky and crashes into a New York street, just outside a move theather Beast and Bishop were exiting. The duo go to check on him, and Psylocke sneaks on Bishop, to the latter's surprise. The woman simply replies she is a ninja.
* StoryArc:
** In issues #305-306 (during the ''Fatal Attractions'' crossover) and #311-313, some X-Men members deal with incarnations of the Phalanx, paving the way for the upcoming crossover ''Phalanx Covenant''.
** In issues #322-325, Storm and a small group of X-Men deal with human killings done by Morlock offshoot Gene Nation and their leader Marrow, on the occasion of the ''Mutant Massacre'' anniversary.
** In issues #341-345, a handful of X-Men are teleported to the Shi'ar Empire to deal with an infestation by members of the Phalanx.
* StoryboardingTheApocalypse: Jean takes a peak inside the collapsing M'Kraan Crystal, and sees what would happen if it breaks - the universe gets destroyed and reborn in a new Big Bang.
* StrappedToAnOperatingTable: In his 1985 miniseries, Nightcrawler is captured by an EvilSorcerer who wants to dissect him to learn the secrets of his teleportation powers. Fortunately, some helpful "boggies" free him while the sorcerer is away.
* SurprisinglyRealisticOutcome: Plays a part in Jean becoming the Phoenix. In order to get into Stephen Lang's base, Peter Corbeau rams a space shuttle into it. Problem is, this damages the ship. Space shuttles aren't designed to ram things.
* TagalongKid: Kitty Pryde joins the team after ''ComicBook/TheDarkPhoenixSaga'' and immediately starts accompanying them on missions despite only being [[InsistentTerminology thirteen-and-a-half years old]]. Xavier attempts to avert this when he establishes the New Mutants and immediately demotes Kitty to that team. She is too stubborn to go along with it and remains on the X-Men regardless.
** Kitty would later be succeeded by another tough young mutant training under Wolverine, by the name of Jubilee.
* TalkingIsAFreeAction: Exaggerated during the Claremont and Lobdell runs. ''Especially'' noticeable with Banshee, who really shouldn't ''be able'' to talk while using his powers.
* TeleportSpam: TropeCodifier Nightcrawler was introduced in this series. Early on, Kurt would have difficulty with this, since using his powers wore him out just as much as it did anyone riding with him.
* TemptingFate:
** When Professor X mentions Moira Mactaggert will be looking after the mansion while he is away, Banshee assumes that she will be some manner of old hag. He is naturally speechless when he opens the door for her, and pretty much falls for her then and there.
** During a fight with a BrainwashedAndCrazy Havok and Polaris, Storm confidently states that Polaris can't fly. Unfortunately, Shi'ar brainwashing comes with taking a level in badass, and so Polaris ''can'' fly.
** The X-Men's first encounter with Jahf. Cyclops tells Wolverine to be careful, since they have no idea what he can do.
-->'''Wolverine:''' ''You'' be careful, bub. That's your bag, ain't it? 'sides, I ain't gonna hurt the little fella much.\\
'''Jahf:''' ''(smirking as he draws back a fist)'' That's for sure...\\
''Next panel:'' *POW*
* [[ThatManIsDead That Woman Is Dead]]: Phoenix's introduction.
-->'''[[LargeHam Phoenix]]:''' Hear me, '''X-Men'''! '''No longer''' am I the woman you once '''knew'''! '''I am fire! And life incarnate! Now and forever -- I am PHOENIX!'''
* ThirdPersonPerson: Early on, Wolverine had a tendency to refer to himself as "the Wolverine" or "Wolverine" when angry or annoyed. Sometimes the other X-Men would get in on this.
* ThouShaltNotKill: Like most superheroes, the X-Men (''usually'') hold themselves to this. Logan at one point goes as far as to stab Rachel (non-fatally) to stop her attempt to kill Selene.
* ThreadsOfFate: Psylocke's elder brother, Jamie Braddock, has a mutation that allows him to see the fabric of reality as literal strings. That means he can pull a thread and kill or revive a person like in UXM #472-474.
* TokenEvilTeammate: During Matt Fraction's run, Emma and Namor, as both were already pretty dark and were secretly part of the Cabal.
* TongueOnTheFlagpole: In #177, a powerless Storm grabs a length of pipe to defend herself when attacked during a blizzard, only to have her hands freeze to to the metal.
* TongueOutInsult: In one issue, Jubilee has been captured by the Mandarin, who has had her dressed in traditional Chinese attire and make-up, and makes loud complaints about her being "sullied by the mongerel ways of the West." Jubilee's most eloquent response to him was to stick her tongue out at him, to his exasperation. Then Wolverine shows up to rescue her, and she ends up blowing up the Mandarin's house.
* TookALevelInBadass: Jean, when she becomes Phoenix, which Scott lampshades.
* TurnedAgainstTheirMasters: The first Sentinels abduct Bolivar Trask and demand he make more of them, threatening to kill him if he doesn't. The mark II Sentinels also turn on Larry Trask, his son, when they realise that he is a Mutant, and kill him. The later Sentinels do not have this problem though, doing ''exactly what they were programmed for''.
* UndressingTheUnconscious: In #144, ComicBook/DoctorDoom captures Storm and [[TakenForGranite turns her into an organic steel statue]]. In the next issue, we see that Storm is not wearing the same clothes when Doom first turned her into steel, meaning he must have somehow changed her clothes while she was in her statue form, putting her into a much more [[GoGoEnslavement revealing dress.]]
* UnexplainedRecovery: Magneto's reappearance in Brubaker's run, since the last time he had shown up was over in ''New Avengers'', where he had apparently been blown up. This goes unaddressed, because hey, it's Magneto. He has had worse.
* UnusuallyUninterestingSight: The X-Men's run in with Kierrok the Damned, the All-New team's first encounter with the supernatural. The precise time they spend asking what the hell (hee-hee) a demon is doing smashing through the living room wall? None. In fairness, Kierrok is kind enough to outline what he is as he is trying to kill them.
* VitriolicBestBuds: Cyclops and Wolverine became this over time, most notable in the few years before ''Schism'', in which they were actually pretty tight, where Jean wasn't concerned. After ''Schism''...
* WeHardlyKnewYe: Thunderbird, introduced in Giant-Sized X-Men and then killed off in the very next story arc, and [[SenselessSacrifice not in a very flattering manner, either]]. His character was mostly fleshed out in flashback stories.
* WhamEpisode: Being a LongRunner, there are several throughout the series:
** ''Giant-Size X-Men #1'': Professor Xavier recruits a second team of mutants to save the first group, bringing in future mainstays Storm, Colossus, Nightcrawler and BreakoutCharacter Wolverine. The following issues sees all of the original members except for Cyclops leave, shifting the status quo in the title for good.
** Issue 95 sees Thunderbird sacrificing himself to stop Count Nefaria’s plot, marking him as the first X-Man to die in battle and showing that as far as the All-New, All-Different era is concerned, AnyoneCanDie.
** Issue 101 features Jean sacrificing herself to pilot the X-Men back to Earth and being reborn as the Phoenix, sparking a 36-issue MythArc that culminates in the most iconic storyline in X-Men history.
** ComicBook/TheDarkPhoenixSaga (#129 - 137) features a WhamEpisode every issue, bringing in major characters (ComicBook/KittyPryde, ComicBook/EmmaFrost, ComicBook/{{Dazzler}}, the Hellfire Club), revealing Jean’s mysterious paramour as Silver Age villain Mastermind, featuring Jean’s transformation into the Dark Phoenix and destruction of a star system, the X-Men’s climactic duel on the Moon with the Shi’ar Imperial Guard and Jean’s HeroicSuicide to prevent the Dark Phoenix from emerging once more. The follow-up issue 138, sees Cyclops quit the team, leaving the X-Men without their leader.
** ComicBook/DaysOfFuturePast (#141 - 142) features Kate Pryde of 2013 shifting into her younger body to warn the X-Men of the dark future ruled by Sentinels. Though the X-Men save Senator Kelly from the Brotherhood of Evil Mutants the dark future is not necessarily prevented as Kelly recruits Sebastian Shaw of the Hellfire Club to enact Project Wideawake to unleash Sentinels on the mutant race.
** Issue 160 has the team go to Limbo to save [[ComicBook/{{Magik}} Illyana Rasputin]], facing twisted alternate future versions of themselves to save Colossus’ little sister. Though they escape Illyana is aged seven years in the process and irrevocably changed due to her ordeal with Belasco, leading to years of stories throughout ''Uncanny X-Men'' and ''ComicBook/NewMutants'' that culminate in the ComicBook/Inferno1988 crossover.
** ComicBook/TheBroodSaga (#161 - 167) features the X-Men getting kidnapped by the Brood and implanted with queen embryos, leading the team to launch a final attack against the aliens in a DyingMomentOfAwesome. Though the X-Men survive and return home Professor Xavier has been so shaken by the temporary loss of his students that he forms the ''ComicBook/NewMutants''. After Xavier nearly succumbs to his Brood embryo and has his consciousness placed in a clone body, allowing him to walk for the first time in fifteen years. [[ArsonMurderAndJaywalking And worst of all, Kitty has to leave the X-Men to join the New Mutants!]]
* WhamLine: Jean, who had previously read Corsair's mind, addresses him as "Major Summers". Just to make it clear what she is talking about, she then tells him that Scott is his son.
* WhamShot:
** In the original run, Angel is recused in the Savage Land by a kindly elderly scientist. He convinces Angel he's a good guy to send him after the X-Men. After Angel leaves, the Creator laughs Angel didn't even recognize him. Opening a cabinet, he muses "perhaps clothes ''do'' make the man" as he rubs...Magneto's helmet. The shock to the reader is that this was the ''first'' time Magneto had ever been shown without the helmet.
** A cross-title one during the 80s. Over in ''Avengers'', it had been mentioned that Wanda and Pietro Maximoff's dead mother was named Magda. In ''Uncanny X-Men'', one issue has Magneto going across his old records, and finds one of his old love... ''Magda''.
* WhatYouAreInTheDark:
** During issue #150, Ororo finds Magneto sleeping, and considers whether it'd be best for the world to just stab him then and there. She hems and haws over the subject long enough for him to wake up.
** Facing the Brood Queen that's taken over Xavier, Kitty has a doodad that'll stop him, but she hesitates, just long enough for "Charles" to reveal he's awake and knows she's there.
* WhenThePlanetsAlign: When a set of nine "death stars" (not ''[[Franchise/StarWars that kind]]'' of death star) align over the M'Kraan Crystal, once every million years, the power of the M'kraan Crystal can be accessed.
* WholeEpisodeFlashback:
** #117 sees Xavier’s first meeting with the mutant telepathy who would go on to become his personal arch-nemesis: The Shadow King, as he narrates to Lilandra.
** #161 sees Xavier’s first meeting with Magneto and their battle against HYDRA to save a Holocaust survivor named Gabrielle Haller, who would go on to be the mother of Xavier’s son: ComicBook/{{Legion|MarvelComics}}.
* WhyDidItHaveToBeSnakes: Storm’s claustrophobia comes up shortly after her introduction [[FreudianExcuse (the result of her being trapped under rubble after being the sole survivor of a plane crash that left her parents dead)]] and comes up several times throughout the years.
* WomanScorned: During Chuck Austen's run, Alex Summers has to learn the hard way that it is a profoundly ''stupid'' move to dump a traumatised woman on her wedding day, ''at the altar''. Especially when that woman has magnetic powers. Polaris goes on a rampage.
* TheWorfEffect: A thing in early Claremont issues involved Colossus getting beaten up by the bad guys. Eventually, even he got sick of being everyone's punching bag.
* WorldOfHam: [[MediaNotes/TheBronzeAgeOfComicBooks Bronze Age]] Chris Claremont, so yeah. Lots of monologuing and shouting to yourself.
* YouKilledMyFather:
** James Proudstar comes after Xavier, blaming him for his brother John's death. He doesn't kill Charles, however, and moves on from this, eventually going on to join X-Force, and the X-Men themselves.
** Vulcan starts off determined to kill D'Ken for murdering his mother. When he finds out D'Ken might as well be dead anyhow, he changes tack to revenge on the Shi'ar in general. Then he revives D'Ken anyway... and kills him at the first opportunity.
* YouAreFat: During a psychic duel, Rachel tries suggesting this about Emma, who shrugs it off with a "so what if I was? Scott still loves me."
* YoureInsane: Darwin, to Vulcan, in "Rise and Fall of the Shi'ar Empire", after he explains what's going on to him. Amazingly for Vulcan, his only response is to calmly threaten Darwin's life, rather than just skip to trying to murder him.
* YourMindMakesItReal: During a fight with Xavier's evil side, it creates an apparent chasm in the floor. The X-Men know it's an illusion, but they note falling into it would still kill them all the same because of this trope.
* YourSoulIsMine: After catching his little sister, D'Ken plans to feed Lilandra to a Soul Drinker. Fortunately, Nightcrawler teleports her away.
