Western Animation / X-Men

PREVIOUSLY, ON X-MEN...

1990s animated series based on the popular X-Men comics.

An ambitious attempt to adapt the most famous comic storylines. One of the most popular series on FOX's Saturday morning lineup, and remembered fondly despite its limited animation quality and a few less-than stellar story arcs. Lasting 76 episodes across five seasons, it is still among Marvel's longest-running shows and considered the most faithful to the original comic book version in comparison to the modern adaptations (particularly the live action ones associated with the X-Men Film Series).

The main characters were:

• Jubilation Lee/Jubilee, the teenage Naïve Newcomer who, at the beginning of the series, has just discovered she's a pyrotechnic-throwing mutant.
• Ororo Munroe/Storm, weather-controlling African native.
• Rogue, Southern belle whose touch drains life, memory and powers, and who begins the series after having absorbed Ms. Marvel's Flying Brick abilities (but also gaining her vengeful consciousness trapped inside her own psyche) in addition to her own.
• Remy LeBeau/Gambit, smooth-talking, card-playing Cajun thief with the ability to charge up objects and make them explode.
• Dr. Hank McCoy/Beast, blue, furry Genius Bruiser whose feet can stick to walls and ceilings.
• Scott Summers/Cyclops, the stolid, straight-faced field leader who shoots force beams out of his eyes.
• Jean Grey, telepathic, telekinetic, and Cyclops's love interest.
• Logan/Wolverine, Anti-Hero Jerk with a Heart of Gold (as badass as one can be in yellow spandex, anyway) with claws, a metal skeleton, and a Healing Factor. Enough Popularity Power to have more spotlight episodes (including solos) than the others combined.
• Morph, jovial shapeshifter who was was killed in the first episode saving Wolverine from an ambush. However, due to the unexpected popularity of the character, he was brought back.
• Professor Charles Xavier/Professor X, the team's mentor and Team Dad, who uses a wheelchair and possesses extremely powerful psychic abilities which he uses with great restraint.

Together, they fought evil mutants, giant robots, government conspiracies, cosmic forces, and occasionally each other, while protecting those who hated and feared them. It is being recapped episode-by-episode by Chris Sims (with occasional jumps to seasonally appropriate episodes) on Comicsalliance here.

Another animated series based on the X-Men comic, X-Men: Evolution, was made in the early '00s, followed by Wolverine and the X-Men in the late '00s. In 2015, this universe was revisited under the title X-Men '92 as part of the Secret Wars (2015) event and returned as a full-fledged ongoing series as part of the All-New, All-Different Marvel lineup. Tropes for this series can be found here.

Tropes

A–D

• Aborted Arc:
  • In "Beyond Good and Evil, Part 2," it is clearly stated that Magneto is only aiding Apocalypse to have his "beloved wife" resurrected. This was not referred to again and a far different motivation was stated in Part 4.
  • "The Fifth Horseman" ends with Apocalypse resurrecting himself by pulling a Grand Theft Me on Cortez, clearly setting him up to serve as an antagonist in the future. And yet, the show never dealt with this before its conclusion.
  • Likewise, despite "Cold Comfort" having Cyclops and Havok puzzled by each other, including their powers not working, nothing is done with their rivalry or even that they're brothers.
• Above Good and Evil: Apocalypse delivers this line in the beginning of the four-parter "Beyond Good and Evil". Before pulling this moral relativism card however, he did have the gall to call Cable an "evil mutant" for trying to stop his genocidal war by attacking the source of his immortality.
  Apocalypse: Evil? I am not malevolent, I simply am!
  • And later on in the same arc -
  Apocalypse: Spare me your petty judgements. They spring from a brain too meager to comprehend my reality.
• Action-Hogging Opening: Especially in the Japanese opening titles, which feature Magneto summoning the Brood, which are an alien species that have nothing to do with him.
• Adaptation-Induced Plot Hole / Series Continuity Error:
  • After seeing a Sentinel attack Storm in "Slave Island," Jubilee confusedly says that she thought the X-Men destroyed all of them. This is despite the fact that the previous episode's cliffhanger involved Jubilee and the others being captured by a Sentinel, meaning she should know better than anyone that they still exist.
  • When Warren Worthington (Archangel) is introduced, he has no connection to Xavier or the X-Men. It's even demonstrated that Cyclops and Professor X don't know who he is. In "Proteus: Part I" and other episodes throughout the series, flashbacks showing the first X-Men include one with big angelic wings on his shoulders. This same winged X-Man shows up in "Xavier Remembers" in a way that confirms he is Angel. Specifically, Xavier has a dream sequence where he sees the X-Men of past and present wearing their original costumes, then sees them transform into their current costumes. One of them is original X-Men uniform Angel, who transforms into Archangel.
  • Adding to this confusion is that - in addition to his original blue and yellow X-Men uniform - Angel shows up in some flashbacks (such as in "Sanctuary, Part 1") wearing a yellow and red costume based on his appearance in X-Men Volume 1 Issue 39◊, further implying that he has deep history with the X-Men before he became Apocalypse's victim. In the episode "Courage", Morph briefly transforms into this appearance of Angel (the yellow and red costume) during the climax.
  • Speaking of "Sanctuary, Part 1," that episode has Beast tell Gambit that Professor Xavier was crippled during his battle with Magneto. The battle between the two shown during a flashback in "Enter Magneto" had Xavier still standing after beating Magneto, with no indication that he'd been injured physically.
  • Cable's appearance in the first season suggests he's been in the present day for quite some time but there's no attempt to reconcile it with his later appearances where he's clearly a man from the future who dives into the present only to Set Right What Once Went Wrong. This may be the result of the series's writers being unaware of Marvel's plans for him. The first season aired 1992-1993, whereas Cable's origin wasn't confirmed in the comics until December 1993. Thus, the series writers likely adjusted to avoid any serious contradictions with the source material. Also of note, whereas there is no attempt to reconcile the two seasons' Cable appearances, the first season is not ignored. Rogue explicitly recalls her first encounter with Cable when the two battle in "Time Fugitives, Part 2." Being a time traveling commando however it can be explained away that his first appearance was him tracking down Apocalypse, who was central to that storyline.
  • "Enter Magneto" was clearly the first time the X-Men encountered or had even heard of Magneto. A flashback in "Cold Comfort" shows the original five X-Men had fought him at least once.
  • Wolverine fights robot duplicates of antagonists he hasn't even met yet: The Shi'ar Imperial Guard (Gladiator, Flashfire, and Earthquake), in the Season 2 episode "Mojovision". He would later encounter the real-deal (who are much tougher) in Season 3.
  • Jean replies to Cyclops when he insists that she couldn't be the assassin who betrays the X-Men, saying that it very well could be her, alluding to her "[bad] moments" and asking if he's forgotten. It isn't elaborated on further, but it's implied it relates to the "The Dark Phoenix Saga", which would only come midway through Season 3.
  • "The Cure" explicitly shows that Rogue has never encountered Pyro and Avalanche before, which contradicts flashbacks in "A Rogue's Tale" in the following season which show that she was previously a teammate of theirs working for Mystique under her old identity prior to the events of the series.
• Adaptation Name Change:
  • When Wolverine revealed that Graydon Creed was Sabretooth's son in "Beauty and the Beast", the latter is identified as "Graydon Creed, Sr." instead of "Victor Creed".
  • Solarr's real name is Bill Braddock rather than Silas King.
  • Kevin Sydney's codename was changed from "Changeling" to "Morph", in part because DC copyrighted it (Teen Titans character Beast Boy was using it at the time). It's since been adapted for the Age of Apocalypse and Exiles incarnations of the character.
• Adaptational Attractiveness: The Shadow King's human body. In comics he's fat and bald. In the series he's a handsome Egyptian with a Badass Beard. The animators based his character design on a later host body of the Shadow King entity, Jacob Reisz, rather than Amahl Farouk, the body he was in when he was introduced in the comics (though perhaps not his original form).
• Adaptational Badass: A lot of people find this version of Apocalypse much more badass than the one from the comics.
• Adaptational Heroism:
  • Magneto. Mags has always been a complex character, doing acts others consider villainy or heroism as needed to protect mutants, so the sight of him helping the X-Men and meaning it is not too surprising in any continuity. However, when he's bad, look out. His list of villainous exploits is impressive, and everyone's leery of him even when he's been playing nice for a while because they know that "what must be done to protect mutants" being helping old ladies cross the street now doesn't mean it won't be "showdown that could well start World War III" someday. In this series, he's only properly villainous in his introductory two-parter, and every appearance after that has him alongside the X-Men against common foes. However, when the show came out, comic Mags had been 95% reformed for about a decade or so.
  • Cable's son Tyler. In the comics he was an Antagonistic Offspring and eventually became a supervillain going so far as trying to follow in Apocalypse's steps. Here Tyler is a straight-up hero and he and Cable are very close. Probably Justified via Stryfe, whose actions caused their relationship to go sour in the original comics, being Adapted Out.
  • Instead of a psychotic monster, Proteus is just a confused child who only wants to see the wider world, meet his father, and be accepted by him. His Body Surf doesn't Possession Burnout, either, for obvious reasons. Also, instead of a vicious rapist, Proteus's father is merely a selfish politician who embraces his son in the end.
• Adaptation Species Change: Zebediah Kilgrave is a mutant, unlike his comic book counterpart whose powers were the result of being accidentally exposed to a nerve agent.
• Adapted Out:
  • Raksor the Skrull and his Kree counterpart are absent from the Dark Phoenix Saga. Raksor is replaced by the imperial guardsman Hobgoblin (as both were technically Chameleon Boy stand-ins), but nobody covers the part of the Kree observer.
  • More significantly, Kitty Pryde. In episodes that were adaptations of stories she appeared in, her role was usually given to Jubilee.
• A Day in the Limelight: Every character gets some time for the viewers to learn about their backstory. (Although some more than others)
• Adult Fear:
  • When Corsair recalls the fateful day that he spent what he thought would be this last moments trying to save his children's life by tying them up into a single parachute, he and his wife witness the parachute catch fire, and feared the worst for them. Although he, by a twist of fate survived and escaped D'Ken star cruiser, it's for this reason that he saw no reason to return to Earth ever again, believing he had lost his family, and that there was nothing there to return to.
  • In "Red Dawn", Wolverine returns to the mansion to find a note from Jubilee, reading took off to Russia help Colossus fight a psychotic, cyborg, mutant Super Soldier who he barely survived his last encounter with. His reaction is obvious.
• Age Lift: In his first appearance, Tyler is shown as a boy/pre-teen. In his second appearance, which is set in the same year as the previous one, he's a young-adult. No explanation is given.
• Alien Invasion: The Phalanx Covenant two-parter and the Brood invasion.
• All There in the Manual
  • There was a reason Cyclops and Havok's powers had no effect on each other when they fought in "Cold Comfort". They are brothers, but unlike the comics, they never find out they're related.
  • The show doesn't really do a good of explaining exactly who Ms. Marvel is or why Mystique hates her so much. In the comics, Mystique started off as a Ms. Marvel villain, and was arguably her Arch-Nemesis. It was only after Ms. Marvel was cancelled that Mystique became a prominent X-Men villain.
  • As mentioned below, Xavier sees an image of Ghost Rider after reading Gambit's mind at one point. This encounter is never explained in the show, but is a reference to a crossover between the X-Men and Ghost Rider books that occurred in the early 90s.
• All of the Other Reindeer: Anti-mutant hysteria, though it grows less prominent after Senator Robert Kelly's life is saved by the X-Men, just before he's elected president. It's still pretty bad, though.
• Almighty Janitor: A literal example in the "Above Good and Evil" four-parter, when Bishop is accompanied by a total nut, who reveals he takes care of the Axis of Time, to Bishop's incredulity. When everyone leaves and time is restored, he transform into his true form: Immortus.
• Alternate Time Line: Almost anything involving Bishop or Cable.
• Alternative Foreign Theme Song: The Japanese dub of X-Men not only has a different theme song, it completely reanimates the opening! It also uses a new ending.
• American Accents: Surprisingly well-done—Xavier is completely believable for Westchester County, Gambit is stereotypical but very consistent, and (not actually American, of course) Magneto has just the right touch of Central European on top of a cultured American accent. Rogue's southern accent isn't really one at all, though.
• An Arm and a Leg: The "Phalanx Covenant" two-parter reveals that Hodge lost an arm and and a leg during the fighting on Genosha.
• And I'm the Queen of Sheba: In part two of the "Days of Future Past" two-parter, Gambit quips "And I'm the Queen of France" in response to being told that Bishop is a time-traveler.
• And I Must Scream: The episodes "The Phalanx Covenant" and "Love In Vain" are good examples.
• And This Is for...: In "Night of the Sentinels, Part 2," as the team trashes a Sentinel facility.
  Wolverine: This one's for you, Morph! ''[skewers Sentinel]'
• Animation Bump: The openings by OLM Incorporated and AKOM are better looking than the rest of the show, which was done largely by the latter studio.
• Artistic License – Geography: "Days of Future Past" has Gambit travel to Washington, D.C., but the monitor shows this as being located in the state of Washington.
• Ascended Extra: Cameron Hodge starts out as some as aide to some guy calling himself "The Leader", who governed Genosha in the episode "Slave Island". He apparently survived the climax of that episode and became the chief antagonist of the two-parter, "The Phalanx Covenant".
• Ascended Fanboy:
  • In "Old Soldiers," Logan objects to his general giving him backup...until he discovers that he'll get to work with Captain America. Logan's thoughts sound as close to squee as he can go without completely breaking character.
  • Nathaniel Essex provides a darker example, as he was an admirer of Charles Darwin's work on natural selection, and immediately concluded not only that Darwin's theories apply to humans as well, but the next evolutionary stage for mankind was fast approaching. Darwin downplayed the validity of Essex's own theories, but Essex became obsessed to the point of becoming an Evilutionary Biologist, and became the supervillain Mister Sinister.
• As Long as There is Evil: Discussed when Beast ponders whether or not Apocalypse, as a personification of evil, can truly be destroyed or if a new evil will simply take Apocalypse's place. Cable replies that he doesn't care. It seems that Apocalypse is killed when his Lazarus Chamber is destroyed in Ancient Egypt and he gets willed out of existence by the collective power of the psychics within the Axis of Time, but he was just banished to the Astral Plane, a featureless dimension. When Fabian Cortez tries to revive him, Beast expresses disbelief at his survival, but Cortez confirms that Apocalypse's essence can never truly be destroyed.
• As Long as There Is One Man: This trope kicks off the four-parter "Beyond Good And Evil", when Apocalypse defeats Cable in the year 3999, and steals his time-travelling device. As Apocalypse is about to rid himself of his mortal enemy, Cable cries that more like him will continue opposing him, and "the world can't stomach his evil forever". Apocalypse scoffs at his outburst, considering himself to be above his moral sensibilities...but then briefly muses on the prospect of having to face guys like Cable, as he had previously done many times in his extremely long lifetime to be a Fate Worse than Death. After refusing to accept this to be true, a time-travelling mishap brings him to the "Axis of Time", and he attempts to remake the universe in his own image. Interestingly, it turns out that Apocalypse himself is also indestructible as an avatar of evil — he can only be sealed away temporarily.
• Audience Surrogate: Jubilee is meant to serve this function, assuming one identifies with her.
• Ax-Crazy:
  • Wolverine, to the point of being a Sociopathic Hero at times.
  • This is played straight with Sabretooth.
  • Apocalypse as well. Even Rogue was taken aback to how nuts he is. This extended to his henchmen, particularly Death (Angel/Warren Worthington) as well. Rogue had to absorb the Ax Craziness to get him to stop.
  • Graydon Creed.
  • Omega Red.
• Back for the Finale: Morph appears in the final episode "Graduation Day," reuniting with all his previous X-Men allies to say good-bye to Professor X.
• Back from the Dead: Jean Grey, of course, as they adapted her plot arcs directly from the comics. Morph came back in Season 2 though he had been intended to stay dead.
• Badass Boast: Every sentence Apocalypse utters is this. Here.
• Badass Bookworm: Beast.
• Badass Longcoat: Gambit.
• Badbutt: Wolverine, (although his popularity hardly suffered for it) Cable and Apocalypse.
• Bad Future: Anything involving Bishop or Cable. Specifically, season one directly invokes Days of Future Past (in the two parter with the same name, whilst arguably the entire season arc is preventing that future), season two has Cable's involvement with an equivalent of the Legacy Virus storyline, and season four opens with the reveal of yet another Bad Future, this one based on open human/mutant war.
• Bad Powers, Good People: Rogue's actual mutant power is to involuntarily take energy from other people through her touch, though she is a kind person despite the influence of people like Mystique in her past.
• Bait-and-Switch Credits: The Western opening has Magneto leading a group to fight the X-Men, which never happens in the show. Two of them (Warpath and Yuri Topolov) don't oppose the X-Men throughout the show.
• Balance Between Good and Evil: The running theme in the "Beyond Good and Evil" four-parter. Apocalypse embarks on his plan to remake existence because he's spent centuries trying to take over the world and has constantly had to face opponents like Cable or the X-Men. Beast also openly wonders if Apocalypse can truly be destroyed since both good and evil are integral to the world. "The Fifth Horseman" would later prove Beast correct—showing Apocalypse's essence still existing.
• Bald of Awesome: Professor X.
• Bare Your Midriff: Rogue's costume is very form-fitting and highlights her toned stomach.
• Battle in the Center of the Mind: A rather common plot device, the most notable being Professor Xavier battling the Shadow King and Rogue dealing with the transplanted personality of Miss Marvel.
• Be Careful What You Wish For: After dispatching the entire team with ease, Dark Phoenix focuses on Xavier and purposefully invokes this.
  "You once told Jean Grey that the greatest joy a teacher had is to be surpassed by his own pupil. Enjoy!"
• Beard of Sorrow: Magneto at one point grows one. And it is glorious. Even Hodge likes it.
• Beast Man:
  • Beast subverts this in as much as his beastly aspects are purely physical.
  • The only-slightly-less-obvious Wolverine and Sabretooth.
• Beneath the Earth: the Morlocks
• Beware the Nice Ones: Beast. You really get to know why he has that codename when a gang of anti-mutant thugs kidnap his girlfriend. And seriously, do not piss off Jean Grey when she's cooking.
• Big Bad: Apocalypse in a more series-wide capacity, since Magneto's Heel–Face Revolving Door was played up. Mister Sinister clearly holds this status in Season 2, though.
• Big Good: Professor Xavier in a nutshell. The "One Man's Worth" two-parter goes to great lengths to show what a hellish place the world would be if he had died before forming the X-Men and preaching peace between mutants and normal humans.
  Bishop: Wow, it's incredible how one kid could mean so much to so many people.
• Big "NO!": Wolverine and some of the Big Bad villains do this.
• Bittersweet Ending:
  • "Graduation Day". While Xavier nearly dies and is saved by Lilandra, he's forced to go away with her in order to live, saying goodbye to the X-Men.
  • The last episode of the "Phoenix Force Saga" four-parter: "Child of Light". It ends with Jean adopting her role as Phoenix and Guardian of the M'Kraan Crystal, saving the galaxy from D'Ken, but leaving the X-Men to make sure it's never misused again, by plunging it into the core of the Sun. Nobody even knew if Jean would come back.
  • The second part of "Storm Front": The X-Men find out that the planet of seemingly noble ruler Arkon, oppresses and enslaves the people from its neighboring planet. This particularly upsets Storm, who herself had been enslaved before, but had fallen in love with Arkon, so after she liberates the enslaved people, she leaves for Earth with the team, yet we can clearly see she is heartbroken over everything that happened.
  • "X-Ternally Yours": Bella and the Guild of Assassins are foiled, but Gambit realizes he's a Stranger in a Familiar Land and severs all ties with those he knew.
  • "A Rogue's Tale": Rogue has to face the truth about what she did to Ms. Marvel, but the episode ends on a hopeful note that Carol may recover one day.
  • "Beauty & The Beast": Beast and Carly can't form a relationship due to anti-mutant sentiment, but she's safe, the Friends of Humanity suffered a major blow, and Carly's father has changed his own bigoted ways.
  • "Love In Vain": The X-Men and world are safe from the Colony, but Cody will never be human again.
• Bloodless Carnage: Averted in the first season finale where the Sentinels attack Magneto. When the X-Men find him under machinery later, he's a bloodied mess and clearly on the edge of death.
• Body Horror: In "Savage Land, Savage Heart, Part 1," Karl Lykos explains that Sauron is the result of Mister Sinister experimenting on him.
• Bouquet Toss: When Scott and Jean get married, Beast catches it.
• Bowdlerise:
  • To avoid mentioning the Holocaust in a kids' show, Magneto's backstory is changed slightly. In this version, he's a refugee from a war in some generic unnamed Eastern European country.
  • And the villainous Hellfire Club became the "Inner Circle Club" (though oddly, their suggestive costumes weren't changed very much).
  • In Corsair's backstory, his wife (who was raped and murdered by the Shi'ar in the comics) was instead "destroyed" by them. It happens offscreen, too, naturally, whereas in the comics it was shown. Though in a partial subversion, "destroyed" sounds a lot worse than simply saying "killed" would have, precisely because it's a lot broader in meaning. The context (and the way Corsair says it) helps, with the Shi'ar officers in the flashback leering at Katherine and calling her a "specimen" before the scene fades out ... They sure implied a lot they couldn't state outright.
• Brainwashed and Crazy:
  • Morph after he was brought back to life by Mister Sinister to manipulate the X-Men, and Jean Grey being manipulated by Mastermind to join the Hellfire Club...although being possessed by the Phoenix also helped.
  • Especially when the previously emotionless cosmic being becomes addicted to human emotions.
• Break the Haughty: Wolverine, during the "Proteus" arc.
• Breather Episode: "Mojovision," which comes in after the emotionally heavy "Beauty & the Beast" and right before the "Reunion" two-part season finale.
• Bring It: In "Deadly Reunions," when Wolverine confronts Sabretooth.
  "All right, you egg-sucking piece of gutter trash! You always liked pushin' around people smaller than you. Well, I'm smaller! TRY PUSHING ME!"
• Broken Aesop:
  • One episode has Wolverine exploiting the bigotry of a bunch of anti-mutant radicals by revealing their leader to be the son of Sabretooth, a mutant, causing his men to turn against him. The X-Men, after all, are trying to bring about peace and understanding humans and mutants, and Wolverine was just fueling the fire.
  • Many of the older storylines involving Nightcrawler made it anviliciously clear that Fantastic Racism is bad, that we shouldn't judge people by their external appearance, and that having horns and a tail doesn't necessarily make you the Antichrist. Enter Chuck Austen, and it turns out Nightcrawler really was half-demon all along.
• The Brute: Sabertooth. Particularly in Beyond Good and Evil.
• Butterfly of Doom
• Cain and Abel:
  • Graydon Creed and Nightcrawler. Ironically, the latter looks demonic, yet he is the Abel of the two.
  • Deathbird and Lilandra.
• Call-Forward: "Descent" features this exchange, as James Xavier talks to Nathaniel Essex about his new experiments.
  James: They speak of sinister experiments you are rumored to perform.
  Essex: Sinister? I'll have to remember that when Queen Victoria knights me.
• Calling the Old Man Out:
  • Wolverine to Professor X when Sabretooth was in their infirmary and Magneto was attacking. "How come we gotta trash your old enemy, but we gotta go easy on mine?" Ultimately, Professor X realized Wolverine was right, realizing that not ALL mutants want peaceful co-existence.
  • Cyclops and Corsair, in a truly gut-wrenching scene.
  • Quicksilver and Scarlet Witch to Magneto.
  • Xavier gets this from Iceman during his guest appearance.
  • Rogue after remembering the Ms. Marvel incident, instead of returning to Mystique's side like she wanted, angrily chews her out forcing her to absorb her powers and ruin a woman's life.
• The Caligula: It's very strongly hinted that D'Ken is or was one. He, on a whim abducted a human couple (which we later find out were Cyclops' parents: Chistopher and Katherine Summers) inadvertently saving them from a plane explosion because he wanted to keep them as "live specimen". He later had Katherine killed in front of Christopher, who would escape from him and become Corsair. Lilandra often wastes no opportunity to call him a "madman", implying his rule wasn't very pleasant.
• Calling Your Attacks: Storm, every time she uses her powers, presumably to explain exactly what she's doing to the audience. Lampshaded humorously during the Spider-Man: The Animated Series crossover. May have to do with the fact Storm is a Large Overdramatic Ham.
• The Cameo: One of the things the series is remembered for. Various Avengers, Doctor Strange, War Machine, Spider-Man (well, his hand and shadow at least), The Punisher, Black Panther, Howard the Duck, and Deadpool are just some of the characters to pop up throughout the series. Numerous mutants from the comics also made these. Additionally, characters with speaking roles in even one episode will tend to reappear in cameos in others.
  • Eagle-eyed observers can spot the Age of Apocalypse versions of Sabertooth and Wildchild in the Bad Future from season four.
  • One of the trick or treaters at the beginning of "Bloodlines" is dressed like the original Silver Age version of Daredevil.
• Canon Immigrant: Morph is an unusual example, as the character who eventually became Morph was originally a reformed villain called the Changeling, who died in a Heroic Sacrifice back in the days of the original X-Men team.
• Canon Foreigner:
  • Jubilee's foster parents.
  • Storm's godson Mj'nari from the episode "Whatever It Takes".
• Cassandra Truth:
  • When Professor X, having previously expressed concerns about his sanity, tries to tell the X-Men that an alien woman popped out of nowhere in front of him and was immediately abducted, the response is not what he'd hoped...
  • When Wolverine is told that Alpha Flight abducted him in hopes of figuring out how to replicate the Weapon X project that only he survived, he spits back that they should already know he lived through the bonding process because of his Healing Factor. The Colonel smugly declares they're going to "probe" him anyway, just to make sure.
• Catch-Phrase: Beast overdoes his "Fascinating" and "Oh dear". Also:
  "The name's Gambit, remember it!"
  Wolverine: "I go where I wanna go!"
  "I am Storm, Mistress of the Elements!"
• Chained to a Railway; Played straight in "Out of the Past, Part 2", where Jubilee is tied to some to subway tracks.
• Chain Link Fence: The opening includes a shot of Jubilee, being chased by an Angry Mob, running into a chain-link fence.
• Characterization Marches On: In his second appearance, Magneto is more of a smug snake, sarcastically wondering if Xavier now wears a toupé. His later appearances will be much closer to the Noble Demon Worthy Opponent he's usually depicted as.
• The Chessmaster: Mr. Sinister; Apocalypse.
• Chewing the Scenery: Apocalypse in many of his appearances (including answering a simple question by Jean as "BECAAAAAAUSE I TOLD HIM TOOOOO!"), Graydon Creed during his Freak Out! when his real father's identity is revealed.
• Chivalrous Pervert: Gambit.
• Christmas Episode: "Have Yourself a Morlock Little Christmas".
• Civilization Destroyer: One episode mentions that Apocalypse was behind the destruction of several civilizations including the Babylonians, Sumerians and Assyrians.
• Civvie Spandex: Rogue wears a yellow, leather bomber jacket over a pair of tights as her uniform.
• Claustrophobia: Storm has this, as always.
• Comic-Book Movies Don't Use Codenames:
  • Zebediah Killgrave appears in "No Mutant is an Island" is never called "The Purple Man," his alias from the comics. Justified because he's trying to appear as a well-meaning philanthropist. He even disguises his face so no one can see his purple skin.
  • Inverted in the first season, where characters almost always referred to each other by code name.
• Coming-of-Age Story: Technically this applies to everyone, but Jubilee especially.

• Composite Character:
  • Professor Oyama is an amalgamation of the Professor Truett Hudson of Weapon X and Lord Dark Wind, the father of Lady Deathstrike.
  • Lady Deathstrike herself has elements of Mariko Yashida, as in this incarnation, prior to becoming Deathstrike, she was Wolverine's lover.
  • The Phalanx are a combination of comics Phalanx and the Technarchy, and act like the Borg.
  • Jubilee has similar traits to Shadowcat.
  • Jean Grey is not replaced by a duplicate with the same memories during the Phoenix and Dark Phoenix Saga, unlike her comic book counterpart who spent all that time recovering inside a healing cocoon. Instead, Jean is resurrected when the Phoenix Force takes a portion of the life force of each of her teammates to resurrect her.
  • Nimrod takes the place of Legion as the one who kills Xavier in the past to cause an apocalyptic timeline.
• Contrived Coincidence:
  • The Juggernaut gets thrown into the ocean, and just walks it off. Where does he emerge? New York, where the X-Men are based.
  • In "The Phalanx Covenant", Beast and Warlock go to meet Forge and Quicksilver at a diner, but get attacked by the Phalanx. Fortunately, Mr. Sinister, who had previously been attacked by the Phalanx and tried to warn the X-Men about them, just happened to be at the same diner in disguise.
• Cool Big Sis:
  • Storm, Rogue, and Jean are this to Jubilee.
  • This is inverted with Shard to her older brother Bishop.
• Cool Old Guy: Professor X.
• Crossover: With Spider-Man: The Animated Series, which ran alongside X-Men. It was pretty much inevitable. In fact, before his series was developed, a cameo of Spider-Man can be seen in one episode saving some civilians of New York from a tidal wave (he wasn't fully shown save for an arm but it was still pretty clear who he was). The series' voice cast were even flown to LA from Canada to record their lines for the crossover.

• Curb-Stomp Battle: X-Men vs. The Shi'ar Imperial Guards. The X-Men were getting creamed...badly. Until the Dark Phoenix shows up.
• Cyborg: Cable, Forge, Apocalypse.
• Dark-Skinned Blond: Shard.
• Dark-Skinned Redhead: Wolfsbane.
• Darker and Edgier: Compared to every other Marvel animated series (since the 1960's 'cartoons'), or rather every action animation till the time, the pilot episode itself gives you a hint that this is very unlike your average Saturday morning action animation. The Marvel equivalent of Batman: The Animated Series—admittedly toned down (largely due to censorship) in comparison, but still a lot harder than, say, Superfriends, or the original animated GI Joe and Transformers.
• Dating Catwoman: Longshot and Spiral.
• Dead Person Impersonation: Dr. Adler was already killed before the episode "the Cure", when Mystique was impersonating as him.
• Deadpan Snarker: Wolverine; Gambit; Cyclops; Bishop; Rogue, even Storm and Jean.
• Decomposite Character:
  • In the comics, the Reaver were composed of several of the Hellfire Club guards Wolverine mutilated in The Dark Phoenix Saga. However, on the show, while the Reavers's debut helped the show's version of the Saga, they appeared before the Inner Circle and hence before the actual adaptation of the Saga itself, meaning that they aren't the guards Wolverine fought in this version.
  • In Days of Future Past, Mystique's disguise as Senator Kelly's aide was a unique one she crafted. Here, she's merely posing as the aide after capturing her.
• Deconstructed Trope: In the episode where the Juggernaut's powers are transferred to someone else, said someone else gets Juggy's Super Strength. Which promptly ruins his life by turning him into an unintentionally-destructive human demolition crew.
• Deliberate Values Dissonance: The culture of Polemachus in "Storm Front" has elements of fascism and slavery which are not immediately obvious, but cause the X-Men severe values dissonance once apparent. Their sympathetic leader Arkon gets to justify their system, in an argument that is surprisingly "gray" for a children's cartoon. Summarized, it goes something like: Their world has resources enough to provide only one of their two nations with a decent standard of living; it used to be that the people who are now the oppressed underclass were the rulers, and then they oppressed Arkon's people; while some features in the system might seem pointlessly cruel to the X-Men, they really do need a very harsh discipline to keep society together on this kind of Crapsack World, or else there will be chaos and ruin for everyone. So in sum, he doesn't necessarily like all of it, but he's doing what's necessary to give his own people, at least, a moderately good life under very trying circumstances. In the end, the X-Men still side with the slaves and help topple his regime.
• Demoted to Extra: Every character in the series had this happen to them. With the obvious exception... Two notable X-Men, Colossus and Nightcrawler, were relegated to cameos and guest appearances. This was thanks to them having been a part of Excalibur in the comics at the time, as well as Marvel's desire to focus on the more current 90's members of the team. Poor Kitty Pryde didn't appear at all.
• Desperately Looking for a Purpose in Life: Mystique apparently does this throughout the series. She never really has any major schemes, and initially served Apocalypse; and the only plot she came up with involved getting her adopted daughter back when Mister Sinister informed her Professor X is out of the way. She even outright tells Rogue that she serves Apocalypse because he gives her purpose, like the X-Men does to Rogue. When he's gone, she's manipulated into a trap by Graydon Creed to eliminate his mutant family, it which point she painfully describes her pitiful life to Nightcrawler.
• Determinator: Most of the characters shared this trait.
• Deus Exit Machina:
  • This happens to Professor X in season 2, as the X-Men had to deal with challenges that were originally resolved by him. A good thing that Jean's a telepath herself (if not as skilled).
  • Rogue had to be written out of the first episode of the Phoenix Saga, with Xavier saying she's on a mission. This may sound random until you realize that her Power Copying and Flying Brick powers would have let her absorb the rescued astronauts' piloting skills and calmly bring down the shuttle unharmed by the solar radiation while the others were safe in the shielded area. No cosmic entity needed. In fact, when Rogue gets back and learns what happened, she blames herself for not being there to do this. In the comics, she hadn't been created as a character yet.
  • Wolverine was thrown this trope during the season 2 finale and the beginning of the Dark Phoenix saga. His adamantium claws would've made breaking out all too easy. Hence why at the beginning of each fight, he is disposed of quite early (thrown off a waterfall in the one case, knocked 5 stories down into the sewers in the other) only to come back when the villains were about to dispose of the other X-Men
• Dirty Communists: The plot of one episode has a group of hard-line Communists revive Omega Red to use as a weapon to restore the former Soviet Union. It didn't go as planned...
• Disappeared Dad: Played straight with Cyclops until he meets Corsair and realizes that he is Cyclops' father.
• Disneyfication: The series' version of the Brood. While they cameoed in their regular forms in "Mojovision" and "Cold Comfort," "Love in Vain" depicted them as humanoid reptiles with mechanical tentacles. They weren't even called the Brood, instead referred to as "the Colony." Their victims are also transformed by spores instead of being impregnated with an egg.
• The Dog Bites Back: Wolverine's backstory has one: He was a subject of the Weapon X program, repeatedly experimented on, culminating in having adamantium fused to his bones, shortly afterwards, he wakes up to discover he has metal claws in his hands, and angrily uses them to escape containment, chase after the director of the program, and rampage across the laboratory. It is unknown if the director ever escaped the destruction of the facility, but it is heavily implied he didn't.
• Does This Remind You of Anything?: The Final Solution. The Friends of Humanity high command wear face concealing cloaks ala the Ku Klux Klan. Also, the Friends of Humanity members wear armbands with an eagle, in a shape vaguely reminiscent of the Iron Cross.
• Downer Ending:
  • Near the end of "Weapon X, Lies, and Videotapes'', they learn that their memories were fabricated, with implications that some might be true. Wolverine pointed out that the fake cabin didn't have the carving of "Logan+Kayla" inside a heart on the door, Wolverine believes their love for each other was real. However, Kayla (now Silver Fox) said that even if that was true "that was another lifetime". The episode ends with a pan to a tree with the carving.
  • In "Repo Man" Wolverine leaves Alpha Flight for the last time, warning them not to come after him, making the hopes of restoring the friendship between him and the group no closer than they first left: which is to say, very distant.
• Dragon Ascendant: After Mr. Sinister was defeated in the Savage Land, Sauron takes up the reins and quickly takes over the area.
• Dragon with an Agenda: Fabian Cortez to Magneto.
• Dreadful Musician: "Have Yourself a Morlock Little X-Mas" shows us that for all the skills Cyclops has, singing isn't among them. Unlike some other examples, Scott even concedes he can't sing.
• Dub Name Change: The Mexican dub of the series was known for changing the name of the characters. Many of the names are fairly direct translations that don't clash with the originals (Cyclops becomes "Ciclope", Storm turns into "Tormenta", and so on), however, some characters got their name completely changed:
  • Wolverine was known as "Guepardo" (Cheetah), possibly to match with his yellow uniform. The correct translation of his name is "Lobezno", but that translation is controversial in the Spanish-speaking community. The named proved popular enough to be used in Western Animation(X Men Evolution Venezuelan dub until the name was no longer translated in future shows in Latin America.
  • Rogue was known as "Titania", possibly to match with her super-strenght. The correct translation of her name would be "Pìcara", which like Lobezno is fairly controversial. This name wasn't adapted for future shows, where she would remain as Rogue.

E–H

• Early Installment Weirdness: Sabretooth's first appearance apparently had him as The Mole for Magneto in the Xavier Institute, but Magneto would later denounce Sabretooth as a savage brute in Season 4's "Beyond Good and Evil, Part 2." Justified because Sabretooth was hired to trash the X-Men's base and failed because he was distracted by his vendetta against Wolverine.
• '80s Hair: Gladiator Lampshaded by Juggernaut
  "Why are we listening to Mr. Bad Hair Day?"
• Emperor Scientist: Magneto was once this in the Savage Land. In his absence, Mr. Sinister took over.
• Enemy Mine:
  • Nearly every appearance of Magneto, but notably the entirety of season 2, in which he is stranded in the Savage Land with Professor X.
  • Beast (who is the only one left after his teammates were captured), Warlock, Forge and Amelia Voght team up with the two Big Bads Mister Sinister and Magneto against the alien threat Phalanx in the two-parter episodes.
  • Beyond Good And Evil sees Magneto and Mystique team up with the X-Men to stop Apocalypse's plot.
• Everyone Loves Blondes: Spiral for Longshot.
• Everything's Better with Princesses:
  • Lilandra qualifies for this, until she becomes the Shi'ar empress.
  • In the fairytale episode, Jubilee casts Jean as one.
• Everything Sounds Sexier in French:
  • Gambit.
  • While they only appear a couple of times, Northstar and Aurora also count.
  • A Russian example shows up in Darkstar.
• Evil Counterpart:
  • Sabretooth for Wolverine.
  • Mystique to Morph.
• Evil Feels Good: In one episode, Storm went mad and create a natural disaster after being hypnotised by Sauron. At the end after everything (including her) had been restored to normal she commented that she never felt herself so free.
  • Dark Phoenix
• Evil Redhead: Mystique.
  • Also the Dark Phoenix.
• Evilutionary Biologist: Mr. Sinister. It was hinted that Magneto was once this as well.
• Evil Will Fail: This accidentally sets off the "Beyond Good and Evil" four-partner. Cable attacks Apocalypse's stronghold in 3999 AD, but the immortal genocidal warlord lures him into a trap to steal his enemy's time portal device, and prepares to execute Cable. He taunts Apocalypse that there will always be those who oppose his plans and that he can never truly win. Apocalypse ponders it for a moment, and acknowledges that he has been fighting the "inferior beings" for many thousands of years and still hasn't won, despairing that he might be stuck like this for all eternity like Sisyphus of Greek myth. Then he uses his new powers and inadvertently ends up in the Axis of Time, the very nexus of all timelines, where he can undo everything to recreate it according to his own design.
• Explain, Explain... Oh, Crap!: In "The Phalanx Covenant," the X-Men have been captured by the shape-shifting aliens with the Beast escaping along with Warlock. Beast contacts President Kelly to tell him of the threat. After getting their location, Kelly says a chopper is on its way "to pick up both of you."
  Warlock: Self-friend Hank, you did not tell the President about Self.
  Beast: We can explain that to him in person.
  Warlock: Query: Then what did the President mean by "both of you?"
• Explaining Your Power to the Enemy: After taking a few hits from Gambit's exploding cards, Bishop explains his mutant ability to absorb energy from other mutants' attacks and transform it into energy bolts, which he then uses on Gambit.
• Exposition of Immortality: In an episode, the X-Men have trapped Apocalypse inside a giant forcefield generated by the spaceship. Apocalypse scoffs at the attempt:
  "Beast... how many peoples have dreamed of my end! You are no closer than the Babylonians with their swords and firesticks!"
• Expy:
  • In terms of his powers and appearance, Morph seems to be based on the obscure 1970s villain turned X-Man Changeling. His original role for the series (to be a new character killed off in the very first adventure, just to show that the series is Darker and Edgier and means business) is very similar to the role of the original Thunderbird when Claremont and Cockrum relaunched the X-Men comic book in the 1970s (Thunderbird himself making a few very minor appearances in the show).
  • In the last season, Jubilee's design looks just like Gi from Captain Planet.
  • In the adaptation of The Dark Phoenix Saga, Rogue, who debuted after the original comic, takes the place of Colossus, due to both having super strength and Colossus not being a regular character in this series. Also, Beast doubles for Nightcrawler in some scenes due to their shared agility and Nightcrawler's absence.
  • The episode Jubilee's Fairytale Theatre was based on a comic which featured Kitty Pride instead of Jubilee. Another one changed because the TV show's line-up didn't match the comic being adapted.
• Fairytale Wedding Dress: Jean's dress in the first marriage (that turned out to be invalid). Her second dress was simpler.
• Fake Memories: The basis of the plot of the episode "Weapon X, Lies and Videotape."
• Fake Weakness: Archangel seemingly learns that an ancient civilization (presumably the Incans) learned of a weakness of Apocalypse at the base of his neck based on the writings discovered by an archaeologist. He continuously attempts to attack Apocalypse in this area, and fails. Later, Apocalypse reveals that he posed as the archaeologist and that the information Archangel received was false: a ruse designed merely to draw him out, and Apocalypse boasts that he is invincible.
• Family-Friendly Firearms: Lasers for everyone. Getting hit does no more damage than a punch, no matter what setting the user says it's on. Averted in Wolverine's flashback episode in World War 2, when German and American troops are shown with realistic firearms though the animation occasionally spoils it, and accuracy predictably suffers.
• Fantastic Racism: Between humans and mutants, obviously. One episode took the theme of prejudice against mutants and turned it on its head when Storm (an African) and Wolverine (a white Canadian) traveled back in time to the 1950s. When the waiter at a restaurant refused them service because Storm was black, she indignantly replied, "That's so pathetic it's almost quaint!" It was made even more of a sore spot because this version of Storm and Wolverine came from an alternate timeline in which they were married. Needless to say, Wolverine didn't take it well.
• Fantasy Helmet Enforcement: Wolverine's regen abilities apparently disappear when he touches a motorcycle.
• The Farmer and the Viper: The X-Men take in Sabretooth (to Wolverine's objections) after he's heavily injured from fighting the police, nurse him back to health, and Professor X even tries to help him fight his inner demons with psychic treatments. He repays this kindness by waiting until most of the group are occupied with Magneto to pull a Wounded Gazelle Gambit on Jubilee to free his arm, and had not Wolverine returned when he did, he almost certainly would've killed her. Wolverine himself gets distracted during his fight with Sabretooth after the rest of the team arrive and Sabretooth nearly kills him, but is driven out by Jubilee. Xavier admits that he was wrong and apologizes to the unconscious Wolverine, for letting his idealism cloud his better judgement.
• Fat Bastard: Mojo.
• Fate Worse than Death: In "Beyond Good and Evil, Part 4," Apocalypse is seemingly destroyed, but in actuality, his essence is trapped within a void. A celestial alignment and a sacrifice is required for him to be fully revived. In the end, Cortez becomes the sacrifice and his essence is shown being sent into the same void as Apocalypse is revived.
• Feeling Oppressed by Their Existence: This is more or less the opinion and motivation of Graydon Creed. Keeping in mind he says the following as if it were fact;
  Jubilee: What did we ever do to you‽
  Creed: You were born!
• Faux Affably Evil: Mister Sinister; Omega Red.
• Fiery Redhead: Jean Grey, which is especially appropriate considering that she later becomes the Phoenix.
• Final Speech: Professor X gets a tear-jerking one in the last episode.
• Fingerless Gloves: Gambit. Of course, he probably needs his skin to make contact with whatever he's charging up, or he might end up charging his own gloves.
• Five-Man Band: A great example.
  • The Hero: Cyclops
  • The Lancer: Gambit
  • The Smart Guy: Beast and Storm
  • The Big Guy: Rogue and Wolverine
  • The Chick: Jean and Jubilee
  • The Sixth Ranger: Any one else with them during their missions.
• For Want of a Nail: In the two-parter "One Man's Worth", it's shown that the death of Charles Xavier before he formed the X-Men, eventually led to human-mutant relations souring to the point of a full blown war taking place in the 90s, and in Bishop's time, Master Mold has all but dominated the world, and nearly wiped out all mutants.

• Friendly Enemy: Professor X and Magneto view each other as worthy rivals on an ideological level, having even been good friends pre-schism

• Foregone Conclusion: Most of the adapted storylines, though there are exceptions, such as the Dark Phoenix Saga.
• Foreshadowing: A number of upcoming episodes are actually given subtle spoilers.
  • The episode "Captive Hearts" - the episode which introduced the Morlocks - had Gambit going sick because of Plague. Said mutant reappears then in "The Cure" and "Come of Apocalypse", asking for a cure and becoming Pestilence, one of Apocalypse's horsemen.
  • In the episode "Slave Island", the governor of Genosha mentions that the power-suppression collars for mutants were created by a scientist in Scotland. Two episodes later in "The Cure", Dr. Gottfried Adler is revealed to have its inventor, as well as the creator of a supposed "mutant cure".
  • In "The Cure", Angel asks Rogue how can she fly without any wings, and she admits that even she doesn't know the answer. In Season 2, we find out that she stole Ms. Marvel's powers and then had all memory of the incident purged from her mind by Professor X.
  • Likewise, in "Whatever It Takes", the Shadow King, while possessing Storm's body, says to Rogue "I understand your body is a little crowded right now", we find out later in the season she has some of Ms. Marvel's consciousness hidden within her mind.
  • Gambit reacts when Bishop accuses him of being an assassin. Gambit's past in the "Thieves Guild" facing the opposing "Assassin's Guild" would come up in the season two episode "X-Ternally Yours".
  • In the last episode of season one, whilst probing through Gambit's mind, we see a brief shot of Bella Donna, his psycho ex-fiancee, who becomes the antagonist of the season two episode "X-Ternally Yours".
  • "X-Ternally Yours" also has one of the Imperial Guard who will appear in season three's Phoenix and Dark Phoenix sagas show up in the initial Danger Room exercise.
  • When Sauron is sent to New York in a vessel that Magneto left behind in "Savage Land, Strange Heart", one of the destination options is Asteroid M, which is the center of the following "Sanctuary" arc.
• Freudian Excuse:
  • "Weapon X, Lies and Videotape" shows Sabretooth's father repeatedly abused him for being wicked (when it was actually his mutation manifesting itself). This was true in the comics, but the episode left it vague which memories were real and which weren't, so take that into account.
  • Sabretooth's son, Graydon Creed was abandoned by Mystique and implied to have been heavily abused by Sabretooth himself all because he didn't turn out to be a mutant like them. Creed would develop a pathological hatred of all mutants.
• Genius Bruiser: Beast
• Gentle Giant: Beast, Colossus, and Tusk come to mind...
• Getting Crap Past the Radar:
  • Evil!Morph in Season 2 seems to like impersonating women, and gets away with a lot that he probably shouldn't in a '90s cartoon. Like seducing Gambit (as Rogue) in what's probably the most overtly sexual scene any character in the show gets...
  • The episode "Time Fugitives" features Rogue calling a Friends of Humanity goon a "peckerwood," which not only sounds perverted, but is also a racial slur for a white person (particularly one who is considered "trailer trash" — uneducated, poor, violent, very close-minded when it comes to dealing with minorities and modern women, and obsessed with all that is cheap and tacky).
  • Chris Sims' recap points out how Gambit's Establishing Character Moment is a shameless and blatant masturbation metaphor.
  • In one episode Rogue had to administer CPR to an unconscious Cyclops: while giving him kiss-of-life and pumping his chest she cries "Come ON, Scott, make a girl feel welcome."; almost like a girl on top trying to have an orgasm...
  • As mentioned under "Bowdlerization", between using the term "destroyed" and having the Shi'ar says call Katherine a "specimen" as they leer at her, they got to imply the rather horrific events of her death.
• A God Am I: Apocalypse is made of this trope. Dark Phoenix and Mr. Sinister go this route too.
• Good Powers, Bad People
• Go Mad from the Revelation: Rebecca, the wife of Nathaniel Essex (who would become Mister Sinister) saw what her husband's work turned him into, then realised that her health being restored was due to him experimenting on her...and then she had to discover the mutants he kept in his laboratory. After releasing them and the ensuing mob destroying Essex's home, it is said she never spoke a word again for as long as she lived.
• Gosh Dang It to Heck!:
  • "That's a darn lie!"
  • Subverted in a later episode when Beast used the word Hell.
• Grand Finale: Twice. The "Beyond Good and Evil" four-parter was intended to end the series, seeing the X-Men join forces with noteworthy recurring characters against the combined forces of Apocalypse, Magneto, Mister Sinister and Mystique to save the entire timeline. When more episodes were ordered, a more heartwarming finale with the X-Men^note including Morph saying goodbye to an ailing Professor Xavier was done.
• Gratuitous Laboratory Flasks: In one episode, Morph is performing a play version of The Strange Case of Dr. Jekyll and Mr. Hyde onstage, using his shapeshifting powers for the show. Whoever the propmaster for the play was went above and beyond the call of duty, considering Morph's lab table is covered in tons of beakers of colored liquids.
• Great Gazoo: In "Beyond Good and Evil" Bishop is stuck in the crossroads of time, and followed by a maniac who poofs in and out of existence, tormenting him. At the end when the X-Men have defeated the villains (With Bishop's help), he's regarding them in a distance and turns into Immortus.
• Hair-Trigger Temper: Wolverine. Rogue has a rather short temper as well, particularly around Gambit, though Gambit himself showed aspects of this early on. Bishop is also something of a hot-head.
• Hammerspace:
  • After having lost his telepathic powers, Professor Xavier is able to produce a boomerang, a spear and a rock out of thin air.
  • In the first episode Morph pulls a gas gun out of nowhere and re-holsters it on his hip despite having no holster.
• Handsome Lech: Gambit.
  • Longshot as well.
• He Who Fights Monsters: Archangel in "Obsession". Left traumatized and broken after he was freed from Apocalypse's brainwashing by Rogue, he spent months obsessing over taking revenge on the ancient mutant, and becomes as fanatical as in his Death persona, if only in the purpose of destroying Apocalypse instead of serving him.
• Hero Antagonists:
  • The Shi'ar Imperial Guard. They oppose the X-Men because they serve the Shi'ar Majestor. During their first encounter, this was D'Ken. Afterwards, Lilandra becomes Majestrix, and when she receives word that the Phoenix (possessing Jean Grey) destroyed a solar system, she orders that Jean as the Phoenix must be destroyed for the sake of all life in the universe. Xavier has her accept a duel of honor between them that the Shi'ar code cannot refuse. And again, the X-Men go into conflict with them, over the life of Jean Grey.
  • Alpha Flight come into conflict with Wolverine in "Repo Man", but they're under the orders of a mad general. When they figure out the general's plan, almost all of them turn on him, and rescue Wolverine.
  • Ms Marvel is one to Rogue, after what happened when they fought, back when she (Rogue) was a villain.
• Heroes Want Redheads: Wolverine and Cyclops for Jean Grey.
• Heroic Sacrifice:
  • Jean Grey in "The Dark Phoenix Saga" as in the comics. The Phoenix Force felt regret over what it had caused, and brought her back.
  • And Jean Grey as Phoenix when she flies the M'Kraan Crystal into the sun.
  • Also Morph who gets killed saving Wolverine in the first episode.
  • Near the end of the series, Mystique takes a laser shot to save her son Nightcrawler's life, and falls over a waterfall.
    • She survived. And was last seeing walking away in tears.
  • There was also Alternate timeline Wolverine and Storm who helped fix the timeline in "One Man's Worth", but erased themselves from history in the process.
• Hidden Depths:
  • Gambit runs around like a carefree troublemaker who does nothing more than chase skirts and throw cards (charged or otherwise), but when he heard news about his family being in trouble and his fiancee Belladonna in the episode "X-Ternally Yours", his carefree demeanor changed, and he stayed serious throughout the entire episode, even its resolution, where he announced never to get involved with them again.
  • Wolverine, of course regarding his Jerk with a Heart of Gold traits. Much of his cynicism comes from some rather bad episodes in his life, such as the Weapon X program, losing the women he loved, and even in the Christmas Episode, where it turned out that his refusal to help Leech was nothing to do with him being a Morlock, but several unsuccessful blood transfusions to patients, one of them being not much older than Leech.
  • Cyclops comes off as an overly-serious, humorless character. But as Jean knows quite well, his passions run deeper than probably anyone else on team.
  • Beast is an affable, jovial character who often has an intelligent and/or humorous quip about any situation, something not expected of his appearance. However, "Beauty and the Beast" revealed that he hides a lot of self-loathing about his mutation, after anti-mutant hysteria flared up when he tried a forge a relationship with a blind patient.
  • Rogue comes off as a fun-loving, high-spirited, wise-cracking Southern Belle, with a bit of a temper, but generally all-around Nice Girl. However, deep down she feels a great deal of loneliness and self-pity due to her powers, and the frustration she can never touch the ones she loves, which almost led her to try and "cure" herself of her mutation.
• High Collar of Doom: Magus's costume in the Fairy Tale episode.
• Hot-Blooded: Wolverine, Bishop, Cable, Sabretooth and Rogue. And even Cyclops also had his moments of this.
• Hot Witch:
  • Appropriately, Wanda the Scarlet Witch.
  • And Storm, who is called a Weather Witch.
• Human Aliens: the Shi'ar, with feathers for hair.
• Humans Are Ugly: Ch'od expresses this opinion upon encountering the X-Men, which is interesting considering his leader, Corsair, is one. Then again, he was specifically referring to the X-Men, who had Beast, and two guys in full-body costumes (Cyclops and Wolverine), which he may have assumed actually look like that.
• Hypnotize the Princess: Jean is hypnotized by one of the Morlocks when the rest of the X-Men come to rescue her and Scott, but it didn't last long, and the X-Men weren't buying it anyway.
• I Lied: In the four-partner "Beyond Good and Evil", Apocalypse gets in this habit:
  • He tricks an evil former empress trying to take back the throne from her sister by promising to abduct said sister, but instead takes one of her sister's body guards for her psychic abilities.
  Deathbird: You promised to destroy Lilandra!
  Apocalypse: I LIED.
  • Later in the same four-partner, after Apocalypse unveils the full omnicidal extent of his evil plan, he admits he was pulling Magneto's leg with empty promises to get him on his side temporarily.
  Magneto: You spoke of creating an alternate future in which mutants would rule, as I have always dreamed!
  Apocalypse: Then you were fool enough to believe me.

I–L

• I Did What I Had to Do: Although Lilandra wanted the Phoenix destroyed, but in the end of "The Dark Phoenix Saga", when it seemingly happened, and Jean was killed, she was just as saddened as Xavier over everything had occurred. She more or less, uses this stance when confronted by Cyclops, who is not having it.
  Cyclops: (bitterly) You've got your justice, Lilandra! (gestures to the crater from the Wave Motion Gun fired at Jean/Phoenix) The universe is safe!
  Lilandra: I take no joy in this, Scott Summers.
  Cyclops: Don't! Not a word!
• I Owe You My Life: "Repo Man" plays it straight in the flashbacks, as Wolverine expresses genuine gratitude towards Heather and James/Vindicator - agreeing to work for their department out of appreciation. However, things obviously didn't work out and Wolverine no longer feels this way.
  Vindicator: We saved you! We gave you back your life! How could you leave us?!
  Wolverine: So I could be your weapon? Sorry, James.
• If You Ever Do Anything to Hurt Her...: Wolverine tells Cyclops in the wedding reception: "If she's [Jean's] not happy, make sure I don't find out." before opening his claws to cut a slice of the wedding cake.
• I Just Want to Be Normal:
  • All the X-Men have had this at some point or other. but the special mention goes to Rogue, who's the one it happens to most frequently. She started feeling like this in the early part of the series, considering taking the "mutant cure", but deciding against it in the end. However, the cure was a ruse to transform mutants into Apocalypse's Four Horsemen.
  • A good runner-up is Beast. While generally very accepting of being a mutant, in "Beauty & the Beast," he openly laments that his powers keep him from having a normal life, associating with his family and from being with the woman he loves.
    • As revealed in the Spider-Man: The Animated Series crossover, he tried to create a cure for mutation. But discard it after discovering that not only will it eradicate the mutant gene, but also the carrier.
  • Of all the X-Men, Cyclops probably had the most sympathy for Rogue's plight during the "mutant cure" story arc, for good reason.
• "I Know You're in There Somewhere" Fight: Cyclops calls out to Jean after the Dark Phoenix takes control of her. Xavier does so later - requesting Jean's help during a psychic battle with the entity.
• In Their Own Image: Apocalypse steals Cable's time travel device in the far future and travels to a temporal center called the Axis of Time. He kidnaps psychics from all eras in history, and then uses their combined power to wipe out all reality so he can rebuild it to his choosing.
• I Surrender, Suckers: Cyclops, in the first episode ("Night of the Sentinels")
  Sentinel: Surrender, mutant.
  Cyclops: Of course. *puts hands up* Not! *takes off glasses and blasts the Sentinel*
• Immortality Inducer: The secret to Apocalypse's immortality is the Lazarus Chamber, an ancient device located inside his pyramidal headquarters in Cairo. It allows him to rejuvenate himself every hundred or so years and restore his power to his prime.
• Immortal Life Is Cheap: Proteus manages to rip Wolverine in half, then melt him into a puddle.
• Implacable Man:
  • As per tradition, the Juggernaut.
  • Nimrod as well. The only way Bishop stopped him was by sending him back to his time.
• Impossibly Cool Clothes: Most of the cast pulls this to some extent.
• Intergenerational Friendship: The rest of the X-Men, especially Wolverine to Jubilee.
• Interspecies Romance: Corsair and his current girlfriend.
  • Also Beast and his girlfriend Carly.
  • And Longshot and Spiral.
  • Professor X and Lilandra.
• Ironic Echo:
  Rogue's dad: <to Rogue> You're not my daughter! Not anymore!
  Rogue: <to Mystique> I ain't you daughter! Not anymore!
• I Want My Beloved to Be Happy: Wolverine for Jean when she marries Cyclops.
• It's Not You, It's My Enemies: This is basically why Beast decides to stop seeing Carly at the end of "Beauty and the Beast", since the nature of his very active battle for mutant rights puts the the people he loves in danger.
• Jack the Ripper: Sinister created him.
• Jerkass Has a Point: Callisto, who previously kidnapped Cyclops and Jean during her time as Leader of the Morlocks to have the former as her consort, bitterly points out that Storm who took her position has not been much of a leader to the Morlocks since, and only came to their assistance when two of them were caught on the surface stealing supplies to help Leech, who became gravely ill. Storm seemed to agree, and after Leech recovered, she abdicated her position and returned it to Callisto.
• It's a Wonderful Plot: "One Man's Worth"
• Karma Houdini: Friends of Humanity organization, Army officials from episode "Hidden Agendas" and Apocalypse.
• Kill and Replace: When Avalanche asks if Dr. Adler was just a fake identity Mystique came up with, she simply replies with "He was real enough...until he met Apocalypse."
• Kneel Before Zod:
  • Vertigo, twice, when using her powers on Wolverine in the two parter, Reunion:
  Vertigo: "On your knees."
  Wolverine: "No!"
  Vertigo: "Surrender to Vertigo."
  Wolverine: "Never!"
  • And:
    Vertigo: "Kneel. Become one of the master's slaves. They cannot help you."
  • Zebediah Killgrave to Cyclops in the final showdown of the episode "No Mutant Is An Island".
  Zebediah Killgrave: ON! YOUR! KNEES!
• Large Ham: Close to everyone.
  • Storm will MEET YOU AT THE MONORAIL! Or her first '''any''' scene showing her powers.
  • Also the Blob: "OH BOY! TUTTI FRUTTI!"
  • Also, Bishop: "ASSASSINS!" * commercial break* "FOR THE FUTURE!!!"
  • Wolverine's snarling delivery of even the silliest of lines.
    • "...TURKEY."
  • Any time Graydon Creed or Sabretooth have a Freak Out!. Justified by Sabretooth being Graydon's dad.
  • "I AM APOCALYPSE! LOOK UPON THE FUTURE...AND TREMBLE!"
  • Cortez and Magneto in "Sanctuary" results in Ham-to-Ham Combat, and it is glorious: "DESTROY THE FLAT-SCAN HUMANS!"
  • Magneto is excellent at being hammy. Watch "Sanctuary," parts 1 & 2, and "Graduation Day" for some prize bacon examples.
  • THE NAME IS LADY DEATHSTRIKE! Yes Yuriko...we know who you are.
• Laser-Guided Karma: Graydon Creed, the leader of the anti-mutant "Friends of Humanity" organization, after failing to eliminate his mutant family, was abducted and flown by his own group to the home of Sabretooth, his father.
• Last-Name Basis: Bishop, whose first name is Lucas.
• Lawyer-Friendly Cameo: A lot of the appearances mentioned in the Cameo section were unauthorized, as many of Marvel's characters belonged to other production companies or networks at the time. Spider-Man and the Hulk robot were two examples of the writers and storyboard artists slipping in characters that had previously been declared off-limits.
• Left Hanging: The last season featured the return of Apocalypse, taking Cortez' body. Sadly, the series ended, and we're... well, Left Hanging.
• Legion of Doom: The "Beyond Good And Evil" four-parter has Apocalypse forming one with Magneto, Mystique, Sabertooth, Mister Sinister and the Nasty Boys, along with Deathbird, although she was quickly abandoned (as was Sabertooth). It quickly breaks apart when Apocalypse reveals his plan to destroy the multiverse, and Magneto and Mystique decide that it's not worth following him.
• Leitmotif: Almost every notable character in the series was given a simple musical tune to play whenever they showed up, from a "Ride of the Valkyries" esque piece any time Storm used her powers, to a discordant series of synth notes for Mister Sinister.
• Lens Flare: Used with blinding potential on Wolverine's claws just about any time he unsheathes them.
• Lethal Chef: Gambit.
• Lighter and Softer: Granted most of the time the show kept to a very dark tone, still many of the storylines adapted from the comics were subject to this. For example the in the comics, Proteus is shown to actually kill, and slowly destroy, his hosts; which is why he was locked up and is so dangerous (for added points, his parents' marriage was quite an unhappy one, and it's hinted he was a Child by Rape). In the show he merely possess them, leaving them with a serious headache; and the episode ends with a Hope Spot about him getting better. Similarly the Phalanx Saga ends with the infected being cured, whereas in the comics infection was a death sentence. Also, despite the countless times Wolverine slashes people, he never draws blood or kills anyone.
• Literal Genie: The Sentinels were programmed to "protect humans from mutants". However, because all humans have some level of genetic mutation, they interpreted it as "protect humans from themselves".
• Limited Animation: Not too noticeable, but it is present, due to the overly detailed character designs and the company who animated them.
• Limited Wardrobe A lot of characters almost never change clothes, even when it makes no sense not to.
• The Load: Jubilee has powers but for the most part, she is treated as a burden as if she has to be babysat
• Loads and Loads of Characters: Though not everyone in the comics at the time made an appearance, the producers did their level best.
• Look Ma, No Plane!: In one episode, Rogue once sat on the wing of a plane when she needed to think, and didn't notice the a passenger was freaking out. He even tries to tell the stewardess, but she just laughs.
• Luke, I Am Your Father:
  • Cyclops finding out Corsair was his father.
  • Rogue finding out Mystique had been her foster mother.
  • Nightcrawler finding out that Mystique was his mother.
  • Graydon Creed is a bit of a subversion as he knew Sabretooth was his father, but being the head of an anti-mutant organization, he was ashamed of it, to say the least. He goes through this for real when he learns that Mystique is his mother, however.
  • Jean discovered that Cable was Cyclops' son, but did not told him. It is implied that Cable already knows.

M–P

• Made of Explodium: You can't go five minutes without something exploding. Even walls are made of the stuff.
• Mad Scientist: Mr. Sinister.
• Magic Genetics
• Magical Security Cam: Magneto's video presentation in "Sanctuary: Part 1" consists of clips from old episodes, including ones where Magneto didn't even appear. How did he get the footage?
• Magnetism Manipulation: The meaningfully renamed Magneto once recovered from being Only Mostly Dead (with the accompanying Meaningful Funeral courtesy of his long time Frenemy Professor Charles "X" Xavier) by crash landing on Earth. the reason? Earth has magnetic fields and it healed him.
• Male Gaze: There is an episode in which Rogue is blasted by Apocalypse so hard her normally-indestructible bomber jacket is burned away (though her even-more-indestructible tights, hair, and flesh are not), she collapses to the ground, the camera positioned behind her...and you are suddenly very aware that she is wearing indestructible spandex
• Mama Bear: Played straight with Ororo Munroe, a.k.a. Storm, in one episode, when her god-child (the son of Storm's best friend in Africa, whom she has known from birth) who's also a mutant is kidnapped and possessed by her arch-nemesis, the Shadow King.
  • Also with Mystique when she takes a laser shot to save her son Nightcrawler's life.
• Martial Pacifist: Beast (unless you kidnap his girlfriend) and Nightcrawler.
• Meaningful Echo: Occurs in the episode "A Rogue's Tale". It is established that Rogue was adopted by Mystique after she ran away from home due to her status as a mutant causing her to be rejected by her father, who coldly said to Rogue "You're not my daughter. Not anymore." At the end of the episode, Rogue makes it clear that she resents Mystique for making her use her powers to render Ms. Marvel comatose by stating "I'm not your daughter. Not anymore."
• Mighty Glacier: Colossus, the Sentinels, and the Blob are pretty slow — and are among the more durable and strongest characters.
• Mighty Whitey: Downplayed, deconstructed, and justified in one episode where Wolverine gets taken in by an Inuit tribe. Being an extremely strong mutant, he easily outperforms the tribe's best net fisher, who is human, and they celebrate him that evening, but he doesn't do much more than that, and never participates in anything that might require a skill he wouldn't have. This unfortunately causes the aforementioned member of the tribe to be extremely upset and humiliated, causing him to try and get revenge on him by helping Sabretooth, but Sabretooth double-crosses him and endangers his tribe while he lures Wolverine away.
• Military Superhero: The only place outside of the comics that acknowledged that Professor Xavier was once a soldier in the Army, as shown in flashbacks in the "Proteus" two-parter.
• Mind Rape:
  • This is Xavier's primary form of combat in the series, though he does mention abhorring it and feel guilty when he's forced to do so. He applied it to Magneto, by having him relive his memories of the Holocaust. It may have had a point in teaching him that violence is wrong, but it is still forcing someone to relive his darkest memories.
  • In the two-parter involving Proteus, he subjects Wolverine to this in conjunction with a physical attack. Afterward, even Wolverine, the archetype of the '90s Anti-Hero, was horrified by the psychic attack.
  • In "A Rogue's Tale", Rogue's mind is invaded by Miss Marvel and she is tormented by it.
  • Then there's what Dark Phoenix did to Mastermind after realizing he was trying to control her.
• Mirrored Confrontation Shot: The opening credits
• Missing Mom:
  • Quicksilver and Scarlet Witch's deceased mother.
  • Discussed between Jubilee and Nightcrawler when the latter receives a message from someone claiming to be his mother that she has kidnapped. Jubilee (herself an orphan) asks Nightcrawler whether he feels anger towards his mother for abandoning him. Nightcrawler admits that there was some hard feelings, but says that his religious faith has largely helped him overcome this, and he has learned to forgive her.
  Jubilee: Woah. This religion stuff is intense!
• Morality Pet: Jean, Storm, and Jubilee (or just about any kid he meets when Walking the Earth) for Wolverine.
• More Than Mind Control: Sinister (and to a lesser extent Morph) both imply that Morph was genuinely angry with the X-Men for leaving him behind, and wanted revenge on his own, though his own mind rejected this to the point that he developed a split personality. At first, Sinister did little more than draft the Evil Morph to help him out (albeit with a mechanical backup). Of note, is the scene where he specifically targets Jubilee (whose death would not help Sinister out in the slightest). She joined the team immediately after his death and became super close with his former BFF Wolverine, and he practically snarls after her "That's for thinking you could take my place". Later in the season, after Sinister's recaptured him, he's been more properly brainwashed into being his slave, though he manages to break free several times and his loyalty to his friends eventually wins out completely. Also of note, in the second episode he casually suggests that humans evolving into mutants is "progress", which is quite in line with Sinister's views, even if he would never voluntarily support his methods.
• Most Common Super Power: It’s slightly toned down for the kids. Fortunately, that didn't stop the ladies' iconic costumes from being super-hot, especially with Emma Frost and the Inner Circle group who keep their sexy kinky outfits from the comics, X-Men members Jean Grey, Rogue, and Storm wear very form-fitting costumes that highlight their very buxom breasts and the Brotherhood member Mystique also wears a form-fitting outfit that highlights her very buxom breasts.
• Motive Decay: Discussed during the "Sanctuary" two-parter. Following Magneto's Asteroid M announcement, Gambit notes how things haven't been very good for mutants despite the X-Men's best intentions. Beast concedes that the team spends more going on adventures and fighting for their lives than fighting for mutant rights.
• Ms. Fanservice: Nearly all of the women who appear in the show are very beautiful and often wear attractive and form-fitting apparel (especially Rogue, Jean Grey, Storm, Mystique, Emma Frost and the other Inner Circle members, and more), regardless of whether they are heroes or a villains.
• Muggle Power: The reasoning behind the Sentinel project and the Friends of Humanity.
• Mundane Utility: Wolverine has used his claws to slice up various meat products, spawning the BLASTED SALAMI and turkey meme.
• Muzzle Flashlight: A scene in the first season finale has Wolverine battle a squad of Sentinels in a dark cave, with nothing to see with except the flashes from the robots' energy blasts.
• My God, What Have I Done?:
  • Archangel (as the Horseman of Death) after Rogue absorbed some of his powers/memories, or as Rogue called it, "the evil within". Also, Jean Grey after reasserting control from the Phoenix entity, who nearly killed Wolverine and almost allowed Cyclops to be killed by Mastermind in mental battle in the Hellfire Club.
  • Brother Reinhart in "Nightcrawler" who leads a mob to kill Nightcrawler and his brothers, whom he believed have been corrupted by the "demon". But after Nightcrawler shows him mercy after saving him from a fall and showed him what his actions have caused (burning the monestary), he falls on his knees and cries that he has "sinned". He later repents.
• My Country, Right or Wrong: Gladiator opposes the X-Men and is ordered to retrieve the M'Kraan crystal. Lilandra notes that Gladiator is a hero and a man of honor, and questions why he'd serve D'Ken. Gladiator replies (quite politely) that he serves whoever is seated on the Shi'ar throne, which is the only reason why he antagonizes the X-Men. He later turns sides and pretty much calls Lilandra the Empress of Shi'ar when D'Ken uses the M'Kraan Crystal to absorb the X-Men, Imperial Guards and the Starjammers and it becomes clear that they're won't be a throne to serve if D'Ken isn't stopped.
• Mysterious Past: Gambit, to which even Wolverine lampshades. Cable also has one, though he's from the future.
• Mythology Gag:
  • In "The Cure", the revelation that the scientist "Dr. Adler" is actually a disguised Mystique should come as no surprise to fans of the comics—he's named in honor of Mystique's lover, Irene Adler (AKA Destiny), who never actually appeared in the TV show.
  • In the series finale, Morph briefly poses as Professor X to help out while the latter is incapacitated. Morph's comic counterpart, Changeling, died while posing as Professor X so that the Prof could prepare for an alien invasion in secret.

• Near Villain Victory: Apocalypse comes this close in the "Beyond Good and Evil" four-parter to permanently wiping out all of existence.
• Necessary Fail: During one of the time travel arcs.
• Never Found the Body: Graydon Creed after he blows up a dam with the military helicopter he flew in, in the climax of "Bloodlines". Wolverine is very smart about it. Turns out he was "rescued" by high-ranking members of his own organisation.
  Jubilee: What happened to Creed?
  Wolverine: What didn't?
• Never Say "Die":
  • Averted in the episode dealing with Gambit's backstory as he says that he left because he was sick of the endless cycle of revenge with, as he put it "Thieves killing assassins, assassins killing thieves"
  • More often played straight, however; the opening storyline manages to kill off an X-Man without ever saying the words.
  • They did semi-regularly use the words "die" and "kill" however, it seemed they were allowed use them, but only sparingly.
  • This is really noticeable in "Till Death Do Us Part". First and foremost, note the title. Also, Morph talks a lot about being "left to die" and Sinister angrily says he should have "let [him] die" when Morph tries to turn against him. But, when Morph is threatening Cyclops, who Sinister needs alive, he delivers the somewhat painful line "Shoot him, and I destroy you". There clearly were more prohibitions on using "kill" than "die".
  • The fourth episode was called Deadly Reunion. Consider this trope averted.
  • Averted, when Cyclops and Wolverine witness security forces confront a berserk Sabretooth. In the third episode itself.
  Cyclops: They're gonna kill him!
  Wolverine: Good...
• Newspaper Dating: Bishop does this when he time-travels.
• Nietzsche Wannabe: Apocalypse.

• '90s Anti-Hero: Cable, Bishop. Wolverine less so.
• No Endor Holocaust: The Dark Phoenix consumed a star to recharge. However, it was stated that the star system had no intelligent life around it—which was technically a good thing, given that it's a kid show. In the original story, the system was inhabited. Still, this didn't prevent the Shi'ar Empire from trying to destroy the Phoenix whatever the cost, and Jean was genuinely horrified by what the Phoenix drove her to do, since it was done largely on a whim and without concern for the lives that could have been lost.
• No Indoor Voice:
  • Apocalypse and Fabian Cortez are prone to shouting many of their lines.
  • A few examples from various characters.
  "STORM, MISTRESS OF THE ELEMENTS!!!"
  "I SHALL MEET YOU AT THE MONORAIL!"
  "I AM AS FAR BEYOND MUTANTS AS THEY ARE BEYOND YOU!"
• No Name Given: Rogue, since it hadn't yet been revealed in the comics. Also, Storm, who was only referred to as "Ororo" twice during the show's run.
• No One Gets Left Behind: Averted in "Night of the Sentinels, Part 2," where Cyclops is forced to order a retreat—leaving Beast to be captured and Morph seemingly dead. However, it's played straight in "The Final Decision."

  Cyclops: This whole mine's gonna go up! Get Kelly above ground! I'm going after Wolverine and Gambit. I'm not leaving anyone behind; not this time.

• Noble Demon:
  • Magneto as always. Really evident in "Beyond Good and Evil," where he stands alongside far more evil villains.
  • Also, Arkon, the ruler of Polemachus with whom Storm fell in love. He's very obviously a brave and capable man, and equally obviously he sincerely cares, both about his people and about Storm. However, his very patriotism makes him ruthless in the pursuit of his nation's interests, and he sees nothing wrong in conquering and enslaving its ancestral enemies, once the balance of power favors his side.
• Noodle Incident: In "The Final Decision," Xavier reads Gambit's mind in order to learn about Henry Peter Gyrich and sees flashes of different events. Apparently, before joining the team, Gambit had a run-in with Ghost Rider.
• Not His Sled: Mister Sinister is infamously known in the comics to betray his "benefactor" Apocalypse, to the point that it gets repeated even in Alternate Universe stories. As for this series, in the "Beyond Good And Evil" four-parter, Magneto and Mystique learn of Apocalypse's plan to annihilate the multiverse and betray him - Sinister actually passes up a chance to join them and stays loyal to Apocalypse. He even says that he was well aware of Apocalypse's plan, and said that challenge him was practically suicidal.
• Not Quite Dead:
  • Master Mold is an odd case of this, being a robot and everything.
  • Magneto pulled this off in "Sanctuary: Part 2", after he was betrayed by Cortez, weakened and sent back to Earth to be killed by the heat from re-entry. However, due to the Earth's magnetic field he survived and initiated a Roaring Rampage of Revenge against Cortez. Magneto then leaves Cortez to die, but the viewers see he was rescued by Apocalypse.
  • Also Morph.
• Not Quite Flight: Magneto and Jean Grey lift themselves using their magnetic and telekinetic powers respectively.
• Not Wearing Tights: Colossus does not wear a costume in either of his two speaking appearances. The closest we get is an alternate version of Colossus wearing his Age of Apocalypse suit during a brief cameo in the Bad Future seen in the "One Man's Worth" two-parter.
• Odd Friendship: Wolverine and Nightcrawler. Could also be said about Wolverine's close friendship with Morph.
• Off-Model: This was frequent^note a side effect between the overly-detailed designs and some less than stellar outsourcing, and one episode it's particularly bad in is when Wolverine goes back to Japan.
  • During the pilot episode(s) the height of the sentinels seems to vary a lot. Between 5 stories tall or twice the height of the average human.
  • The car Rogue drives in season one switches from an automatic to a standard between "The Cure" and "Days of Future Past, part 2", respectively.
  • Other little mistakes, like lumpy drawings; wonky expressions; and shading abuse are also reoccurring errors throughout the series.
  • The final six episodes were animated by a different animation studio, causing noticeable differences in:
    • Jubilee's eyes are changed from brown into blue.
    • She also got a new hairstyle (a shoulder length bob with bangs instead of her usual crop), which resembled her Generation X design. Presumably, it was changed to make it easier to draw, since they were now using a cheaper, lower quality, animation studio (Not that the previous studio was any better, or cheaper).
    • Beast's appearance is far more human-like. His hands didn't even have claws.
• Oh, Crap!:
  • Beast's "Oh, dear" quote.
  • A good example of this is when The Juggernaut comes barging in, trounces Wolverine, and the Gladiator arrives for Lilandra, No Sells a hit from Juggy then painfully grabs his arm and tosses into the horizon, the X-Men collectively soil their pants.
  Jubilee: I thought no-one could do that to the Juggernaut!
  Gambit: (glares at the descending Gladiator) Nobody from Earth.
• Omnicidal Maniac:
  • D'Ken wanted the power of the M'Krann Crystal and didn't care how many would die if he want through with his plans.
  • Apocalypse is this mixed with A God Am I and crossed with a psycho survivalist. He wants to kill everyone he deems unfit and rule over whatever's left. As early as his first appearance in the show he announces his intent to destroy the world to Mystique. It's more evident in the "Beyond Good and Evil" four-parter, in which he plans to wipe out all of existence and start from scratch.
  • Omega Red wanted to fire off nukes to plunge the world into chaos, so he could take it over.
  • Graydon Creed and the Friends of Humanity in regards to mutants. Seriously, they make Joe McCarthy look like a choir boy. Just look at the quote above.
• On the Next: The episode preceding the Phoenix storyline ends with a shot of the earth from space; a wall of fire blazes up behind it, with a caption over the flames: "Coming soon: The Phoenix Saga".
• Only Friend: In the finale, Magneto remarks that Xavier is his only friend.
• Ooh, Me Accent's Slipping: Many of the voice actors are Canadian, and never is this more obvious than when Jubilee says "Sorry" like "Soh-ry" instead of "Saw-ry". Morph's voice actor does fine in the first few eps, and his season 2 return, but starts slipping badly when the character is brought back for a cameo in season 4.
• Origins Episode: The episode "Descent" reveals the origins of Mr. Sinister.
• Papa Wolf:
  • Wolverine to Jubilee
  • Cable to Tyler.
• Parental Abandonment: Unfortunately there are plenty of choices.
• Perma-Stubble:
  • Gambit.
  • Wolverine, who has regrowing his facial hair as a mutant power, and it's Canon.
• Pink Means Feminine: Jean has some pink clothes, like a pink evening dress. Overlaps with Princesses Prefer Pink and Graceful Ladies Like Purple in the fairy tale episode, where Jubilee cast her as a princess.
• The Pirates Who Don't Do Anything: Magneto starts out with a couple of respectably villainous attacks on a military base and a factory, and he has a brief stab at assassinating Senator Kelly, but after that, virtually every time he showed up it was in an Enemy Mine situation of some sort. And he was supposed to be the villain of the show.
• Playing with Fire: Pyro and Sunfire.
• Plot Hole: When the episodes were originally aired, Jean Grey (then as Phoenix) apparently returned off-screen to kickstart the Dark Phoenix Saga... despite no episodes in between showcasing about her return. Later on in Season 5, three misplaced episodes were supposed to air during Season 3 (the Phoenix Saga season) showing Jean's return. With that said, no episode of her returning actually was produced. There was a flashback of her return, in the first episode of the "Dark Phoenix Saga" though.
• Politically Correct History: Averted in an episode when Storm travels to the past and she won't be served in a restaurant because she was holding hands with a white man. As someone who's used to being persecuted for being a mutant, she comments that just plain old-fashioned racism is "so pathetic it's almost quaint." Rather daring, for a Fox Kids cartoon.
• Power Glows: When Cable confronts Apocalypse in his Egyptian temple, Apocalypse glows with bolts of purple energy while he's really pissed off.
• Power Incontinence: Rogue is not only unable to control her ability-absorbing power, but is also frequently unable to control the powers she absorbs with it, though the latter could be due to being unfamiliar with the power.
• Power Loss Makes You Strong: Professor X showed himself to be even more badass than Magneto when they both lost their powers (and Xavier's spine was also magically repaired, to be fair). Xavier did have the power to pull a spear and a boomerang from NOWHERE.
• Pragmatic Adaptation: There were at least two storylines in this series adapted from the comics that were still ongoing in the latter:
  • Bishop travelling to the present from his timeline which he believes Gambit to be the traitor of the X-Men, and ultimately, the cause of his Bad Future in the cartoon turned out to be Mystique impersonating Gambit to frame him and the X-Men. In the comics, the traitor of the X-Men turned out to be, ironically Professor X himself, as Onslaught.
  • The Legacy Virus storyline become "the mutant plague" in the cartoon, and was resolved by Wolverine infected with the plague, only for his accelerated healing abilities to create antibodies in his system, rendering him immune to the virus. Beast uses the antibodies in Wolverine to quickly synthesize a cure. Whereas in the comics, the storyline takes ten years to resolve, with several characters dying from the virus, only for Colossus to sacrifice himself to cure the Legacy Virus by injecting himself with Beast's formula. Interesting to note, that in the cartoon, Apocalypse masterminded both plots.
  • The Phoenix Saga episodes. Eric Lewald recalled that they largely retained the core of the storyline. Many scenes and dialogue were reused, while the more extraneous material (such as the leprechauns) omitted. Other elements were understandably tweaked, such as substituting for characters that weren't regulars (such as Rogue in place of Colossus).
• Present Day
• Previously On: The words were so often repeated in the series due to it having so many multi-episode-spanning storylines (Twelve 2-part episodes, two 4-part episodes, and one 5-part episode, making for 37 out of the show's 78 episodes, a staggering 47% of the total run!), that even years later, many fans say they can merely just read the words "Previously, on X-Men..." and hear them spoken in Cyclops' voice.
• Psycho Ex-Girlfriend:
  • Lady Deathstrike to Wolverine.
  • Spiral to Longshot, in their second appearance.
  • Belladonna to Gambit. Unlike the other two examples here, she will wants to be with Gambit; she just wants to make him suffer a little first for running out on her.
• Psychopathic Manchild: This series's version of Kevin McTaggert aka Proteus, though with more Manchild and less Psychopath than usual (and much more sympathetic than his comic-book counterpart). Also a "Well Done, Son!" Guy. And it's heartbreaking.
• Puberty Superpower: The backstories of most of them, but Jubilee especially.
• Pulling Themselves Together: Sinister's body is almost totally indestructible, and when blown to pieces he begins to reform immediately. Jean scatters his components all around the globe, and it takes literal years for him to reform.
• Put on a Bus: After Morph's death is retconed, this happens to him a lot. First, you could kind of say this retroactively happened to him throughout season one. Then, after the reveal of his Not Quite Dead-nes and subsequent Roaring Rampage of Revenge he vanishes for most of season two, returning in the season finale. He's then promptly put on a bus to Muir Island until the final episode except...
  • The Bus Came Back He does come back for a Day in the Limelight in season four.

Q–T

• Quickly-Demoted Woman: As the series began, the USA was featured as having a female President. She didn't have too much screen time or characterization before her term was over and Senator Robert E. Kelly took over as the new President. She completely left the series after that and we never learned what she did after no longer being the President.
• Rape Discretion Shot: As described under Bowdlerization, this was done in everything but name for the fate of Corsair's wife at the hands of the Shi'ar.
• Really Gets Around: Mystique.
• "The Reason You Suck" Speech:
  • In "Beyond Good and Evil, Part 2," Psylocke calls Angel out on being a self-hating mutant and wasting resources hunting "a creature that can never die."
  • Magneto to Xavier in "The Final Decision":
    "You've lost, Xavier. Admit it. Peace between mutants and normal humans is only a dream—your foolish dream. If you try to rescue Kelly, you'll be throwing your lives away for nothing."
  • Mister Sinister openly mocks both Xavier and Magneto's goals in "Reunion, Part 2":
    "You'd rather fawn over humankind in hopes of a sniveling co-existence, or fight among yourselves to prepare for a war. You cannot win."
• Rebellious Spirit:
  • Wolverine, versus Cyclops.
  • Iceman, in his episode "Cold Comfort".
  • Jubliee has moments of this, as well, though certainly not as extreme as most of the above.
• Red Eyes, Take Warning: Played straight with Mr. Sinister. Also Master Mold, Omega Red and the Sentinels.
• Reluctant Mad Scientist: Heather Hudson provides a very sympathetic example as she's ordered by her superior in Department H to set a trap for Wolverine and lure him back to Canada so that he can rejoin Alpha Flight. As Wolverine would predictably refuse, she's tasked with probing him to discover how he survived the adamantium-bonding process in the Weapon X project, so that they'd create a new Weapon X. Heather only went along with it to make sure it's done humanely. In fact, when the probing doesn't reveal any answers, she's so horrified at her boss and husband's suggestion to have Logan vivisected that she quits working for Department H.
• Ret Gone: In the 2-part episode based on the "Legacy Virus" arc, while Cable was fighting Apocalypse in the further future, a tornado suddenly appears and started sucking Cable's mutant comrades. His Companion Cube tells him they're being erased from existence, due to their timeline changing, caused by Bishop's action trying to prevent his Bad Future.
• Revenge Before Reason: Lady Deathstrike sets a trap for Wolverine to open an alien (Shi'ar) spacecraft with his adamantium claws so that she and the Reavers can steal the treasures it was suspected to have. Daethstrike gets so obsessed with vengeance that she forgets about the plan and tries to kill Wolverine. It's only when the Reavers sternly remind her of the plan, that she relents, and instead swears to have Wolverine's skeleton as a trophy when all is said and done.
• Rival Turned Evil: Morph in season 2 until he gets better in the season finale.
• Roaring Rampage of Revenge: When Morph returns Brainwashed and Crazy in season 2, he tries and almost succeeds in killing most of his "former" friends in revenge for leaving him to die.
  • Magneto goes on a destructive rampage after surviving Cortez's assassination attempt has this against Cortez, one that puts everyone on Asteroid M at risk, forcing them to evacuate.
• Robotic Reveal: In the four-part episode "The Dark Phoenix Saga", Donald Pierce reveals that he is a cyborg by tearing off his sleeve to expose his robotic arm.
• Running Gag: Wolverine doesn't like being teleported...or ducks.
• Rotating Arcs: Between Sinister, Apocalypse, and the Shi'ar.
• Royals Who Actually Do Something:
  • Lilandra, who actively opposed her brother.
  • D'ken as well. An emperor who goes with his ship across the cosmos, collecting specimens of alien species? Seriously, doesn't he have a fleet for such menial tasks?
• Royally Screwed Up: All the royal members of the Shi'ar Empire that were shown in the series seem to be insane and power-hungry, save for Lilandra.
• Sacrificial Lamb: Morph. He returns for the second season and has a final return in the series finale, as Xavier is dying.
• Sadistic Choice: "Graduation Day" provides a villain variant, as Magneto must either choose between leading his new mutant army to achieve his own dream or calling it off in order to save Xavier's life.
• Sanity Slippage: Graydon Creed has an epic meltdown when the truth about his father comes out. When he reappears in "Bloodlines," we're told he spent a year in a mental institution.
• Save the Villain:
  • In one episode, Juggernaut starts an all-out attack on Xavier's mansion, but is stopped when somebody else steals his powers. Cain Marko then starts to die, requiring the X-Men to find the Ruby of Cyttorak to restore his power and save his life. They do, and Juggernaut repays them by stopping the attack and leaving.
  Cyclops: We're going to save the Juggernaut's sorry life. And don't bother telling me you don't like it.
  Wolverine: I don't like it.
  • After first becoming trapped in the Savage Land, Xavier saves Magneto's life - much to the villain's astonishment.
    Magneto: Your life would be infinitely easier if mine were to end, yet you saved me.
    Xavier: I do not yearn for an easy life, Magneto - only a just one. I would take little satisfaction in your death.
  • "Remember Mr. Creed, a mutant saved your life."
• Say My Name: "JEAN!" was only slightly the most frequent one, as every major character's name get shouted a few times over the series.
• Scary Black Man: Bishop, in a departure from his tough but smart comics counterpart.
• Separate Scene Storytelling: "Jubilee's Fairytale Theater" does this with a story Jubilee tells to kids on a field trip.
• Serious Business: Never mess with Jean's cooking if you know what's good for you. Gambit learns this the hard way.
• Sesquipedalian Loquaciousness: Beast, of course.
• Set Right What Once Went Wrong: Subverted: Bishop preventing the dark, Sentinel-dominated future caused an even worse future down the line.
• Shapeshifter Guilt Trip:
  • Morph, during a Story Arc where he was Brainwashed and Crazy, shapeshifts into Wolverine's most hated foes (including Sabretooth and Omega Red), trying to take advantage of Wolvie's fractured and tormented memories of said foes to drive him to insanity. Unfortunately for him, Wolvie's got plenty of experience with repressing those memories, and he only escapes by taking advantage of the one memory Wolvie can't repress: being forced to leave Morph to die after a semi-botched mission. There's also the the time when he shapeshifts into Jean, and calls him a freak compared to Scott, before laughing and running away.
  • Similarly, Mystique shapeshifts into Ms. Marvel to dredge up a bad memory in Rogue of her past to try and guilt her into abandoning the X-Men and hook back up with her; the memory was of Mystique ordering Rogue to fully absorb Marvel's powers and personality, an action that caused Marvel to pop up on occasion as accusatory hallucinations. Rogue eventually had to ditch Mystique as a result, joining the X-Men and having Professor X block her mind of Marvel and the incident to keep the hallucinations at bay, but since he was at this time MIA and unable to keep the block in place, Mystique was trying to convince Rogue that she was the only one in the world who could help her with it.
    • However, this only made Rogue remember why she left Mystique in the first place.
• Shout-Out:
  • In "The Juggernaut Returns," the new Juggernaut crashes through a roof and into a studio with spandex-clad fighters and garish monsters in a city backdrop. An MMPR sting is even used for this scene.
  • "It's adamantium-tasting time, boys!"
  • There's also this set of lines between Sabretooth and Wolverine in "Beyond Good And Evil".
  Sabretooth: I'm through playing around!
  Wolverine: What are you going to do, eat your spinach?
  • In the Dark Phoenix Saga, Wolverine scaring the hell out of a guard is straight from the comic, but the animated dialogue adds this:
  Wolverine: I know what you're thinking, punk. Question is, "can I get Wolverine before he can turn me into shishkabob with those claws?" Well, bub, seein' how these claws are made of adamantium, the strongest metal known and can slice through vanadium steel like a hot knife through butter, buddy, you gotta ask yourself: "Do I feel lucky?"
  • When confronted with Bishop's impending revelation from the future (Days of Future Past, part 1):
  Wolverine: Are any of you listening? Mr. Terminator here claims that an assassination's gonna take place, that's gonna ruin the world...
  • When the X-Men hijack the shuttle to get to Eagle One, pay attention to the symbol on the astronauts' uniforms and space suits.
  • During the brawl at the 50s diner in "One Man's Worth," Logan is assisted by a young biker who looks exactly like Johnny Strabler.
  • When Mojo arrives in their dimension, he has the X-Men battle a purple T-rex:
  Spiral: A big purple lizard?
  Mojo: Kids love it!
  • In the "Phalanx Covenant" two-parter, the titular villains say "You will be assimilated" and "Resistance is futile," two of the Borg's Catch Phrases from Star Trek: The Next Generation.
• Shout-Out to Shakespeare:
  Beast: ... if you prick us, do we not bleed?
  Judge: Don't tempt these people, Mr. McCoy.
  • In the same episode:
  Magneto: Oh, what a brave new world that has such people in it.
• Shut Up, Hannibal!:
  • This seems to be Mister Sinister's other Achilles' Heel, particularly with Cyclops.
  Cyclops: I warned you before to leave us alone!
  Mister Sinister: I can't! I won't! The world needs—! (gets blasted)
  Cyclops: What was that? I don't think I heard you right.
  • In "Beauty & the Beast," Wolverine infiltrates the Friends of Humanity and later interrupts his interrogation of Carly.
    Creed: You have no right to—!
    Wolverine: [extends claws] These give me plenty of rights.
• Sibling Yin-Yang: Professor X and Juggernaut.
• Significant Green-Eyed Redhead: Jean Grey (unless the art was off).
• Skunk Stripe: Rogue, naturally.
• Sociopathic Soldier: Omega Red for the Soviet Union.
• Something They Would Never Say: An inversion after Morph shapeshifts into Wolverine to fight him. Jubilee is confused as to which one to shoot, but when one yells out: "shoot us both, it's the only way to be sure!" she naturally shoots the other one, assuming this is something only the real Wolverine would say. Only it was Morph who said it and the real Wolverine who gets shot, Morph having used this exact trope to his advantage.
• Southern Belle: Rogue.
• Space Pirates: Corsair and the Starjammers.
• Spanner in the Works: Apocalypse's plan in "Beyond Good and Evil" was succeeding, but he was unaware of Bishop's presence until it was too late.
• Split Personality: Morph, as a result of Sinister's Brainwashing.
• Spock Speak: Storm. Xavier. Colossus. Nightcrawler. Magneto. Sinister. In short, lots of people use this.
• Spotlight-Stealing Squad: While the first three seasons tried to focus on the characters fairly evenly, seasons 4 and 5 seemed to focus less and less on anyone who wasn't called Wolverine, except Rogue, Xavier and Beast. At the other end of the spectrum, Gambit appears in far fewer episodes in Seasons 4 and 5.
• Spot the Imposter: Subverted, because Morph was smart about it.
  • Warlock realizes President Kelly is now part of the Phalanax when he says he's sending a chopper to pick up "both of you"...when Beast never said he was with someone.
• Starcrossed Lovers: Professor X and Lilandra provide a literal example.
• Start of Darkness: Season 5 flashes back to Victorian England for Mr. Sinister's origin story.
• Stock Audio Clip: This happens a lot, most notably Beast saying "Fascinating" and "Oh dear".
• Storybook Episode: "Jubilee's Fairytale Theater"
• Stranger in a Familiar Land: Gambit in "X-Ternally Yours." He left home years earlier to get away from the Thieves/Assassin feud, admitting he was young and afraid. When he returns older and more experienced, he recognizes the feud as more pointless than anything else, as well as sees no ties between himself and his family or old friends.
  "I am not assassin or thief. I am an X-Man, and I'm never comin' back."
• Super Hero: Of course, as the X-Men were one of Marvel's main superhero franchises.
  • Superhero School: Though the school aspect is downplayed, as opposed to later series like X-Men: Evolution.
• Super Not-Drowning Skills: The Juggernaut.
• Super Senses: Wolverine
• Superpowered Evil Side:
  • Jean Grey becoming the Dark Phoenix.
  • Karl Lykos becomes Sauron when he absorbs a mutant life-force.
• Superpower Lottery:
  • Storm, mistress of the elements.
  • Apocalypse is a better example. The guy has literally every physical superpower, uses telekinesis, and fire concussive energy attacks powerful enough to wipe out the X-Men in a single shot, and let's just say its a bad idea to try to scan his mind. Oh, and he can steal bodies in case the body he's in either dies or otherwise can't be used anymore.
  • Magneto. You can do a lot with the power over magnetism. At his better showings, he gave Apocalypse a run for his money.
• Super Registration Act: Plot of the first season.
• Supreme Chef: Jean.
  • And Gambit, as shown in the Christmas special.
• Take That!: During an episode from a later season, a child is seen wearing a T-shirt that says "BS&P Rules". The Broadcasting Standards and Practices group had heavily censored this show, as well as Spider-Man.
• Team Mom: Jean Grey. A case could be said for Storm as well.
• Techno Wizard: Beast and Forge.

• 10-Minute Retirement: Cyclops in "No Mutant Is An Island".
• Tentacle Rope: Magneto's former savage land base that Mr. Sinister later takes over (it's unknown who added the tentacles, though it was probably Sinister).
• Terminator Twosome: A two-episode arc involved Bishop traveling from the Bad Future to the present day, attempting to prevent the outbreak of a mutant plague. His actions backfire, however, and result in the deaths of the X-Men and the complete extinction (rather than just decimation) of mutants, so Cable comes from an even further future to stop Bishop.
• That Man Is Dead: Several:
  • In "Come the Apocalypse"
    Archangel: Worthington is no more. Now, there is only Archangel. Let the world beware.
  • In the "Dark Phoenix" multi-parter
    Dark Phoenix: The mortal known as Jean Grey no longer exists. There is only...PHOENIX!
  • In "Out of the Past, Part 1":
    Lady Deathstrike: Yuriko no longer exist. I am Lady Deathstrike!
  • At the end of "Descent":
    Mister Sinister: Essex is no more. From this day forth you will address me as Mister Sinister!
• The End of the World as We Know It: A few times
• The Juggernaut: Juggernaut!
  • Apocalypse even more so.
• The Tease: Rogue, despite (or perhaps expected of) her power/life-force absorbing ability.
• The Masochism Tango: Danced by Rogue and Gambit due to her life-force draining powers.
• The Virus: The Phalanx, the Brood
• The Worf Effect:
  • There was a Worf chain reaction during the Phoenix saga. Wolverine gets curbstomped by the Juggernaut... who, minutes later, is used to show that even an "unstoppable" character is no match for Gladiator. Five minutes later, Gladiator got this by Phoenix in her fabulous entrance.
  • This tends to happen to Wolverine pretty often too. It didn't help that he wasn't really allowed to use his claws (despite constantly unsheathing them) in any violent way except against robots or offscreen.
• They Called Me Mad!: In his Start of Darkness episode, Mr. Sinister's wild theories about human mutation cause him to be derided by his scientific peers. Then he starts ranting at all of them about how soon men will have the powers of gods, which couldn't have helped.
• Third Line, Some Waiting: The subplot in which Professor X and Magneto are trapped in the Savage Land throughout season 2.
• Third-Person Person: Gambit
• This Cannot Be!:
  • From "Come the Apocalypse":
    Apocalypse: No! My creatures cannot be defeated! *I* cannot be defeated!
    Cyclops: [blasts Apocalypse] We beg to differ.
  • From "Dark Phoenix, Part 3" after Xavier gets Jean's help in the mental battle:
    Dark Phoenix: This can't be! I am Phoenix!
• Those Two Bad Guys: Pyro and Avalanche.
• Time Travel: Episodes with Bishop and/or Cable involve this.
• Token Good Teammate: Heather Hudson, for Department H, initially. Even though she was the one who planned the trap for Wolverine to return to Canada and have Alpha Flight capture him, and was tasked with probing him, she was also the one that felt the most guilt about betraying Wolverine's trust, and stopped the project immediately when she felt it was getting out of hand and tended to Wolverine. She even quit her job when she was ordered to retrieve Wolverine's adamantium skeleton. Later subverted as it turned out the rest of Alpha Flight had no prior knowledge of this plan, and instead worked to free Wolverine when they realized what was going on.
• Took a Level in Badass: Morph apparently did while at Muir Island, if the difference in his performance in "Courage" vs "Night of the Sentinels" is any indication.
• Too Powerful to Live: Apocalypse. To the point he actually believes he's "...as far beyond mutants as they are beyond you [humans]!"
• Trapped in TV Land: Happens in 'Mojovision' episode.
• True Companions
• Tsundere: Rogue.
  Rogue: (covers Gambit's lip with her hand and kisses it) I hate you!
  Gambit: (shrugs his shoulders) I don' understand dis woman.
• Truer to the Text: While the series may have had the cases of Adaptation-Induced Plot Hole (along with Series Continuity Error), Adaptation Name Change, Adaptational Badass, Adaptational Heroism, Adapted Out, Animated Comic Book Shows Don't Use Codenames, Composite Character, and Expy, It is the most faithful adaptation of the Marvel Comics series as well as X-Men (along with the members of the group as well as their mythos, costumes, origins, enemies, etc) in general in comparison to all of the X-Men adaptations that have been created after the show (both animated and live action).

U–Z

• Unresolved Sexual Tension: Toned down to Unresolved Romantic Tension, but it can be found in spades between Wolverine and Jean, as well as Gambit and Rogue.
• Unexplained Recovery: No matter how badly hurt someone is, even to the point of seeming to be totally destroyed, they will always return. Part of this is the limitations of a kid's show and part of it is just Status Quo Is God.
• Universal-Adaptor Cast: Jubilee's fairy tale.
• Unwilling Suspension: A few times, like when Jean was first captured by the Morlocks. Jean was able to free herself very quickly, though.
• Villain with Good Publicity: Purple Man.
• Villainous Breakdown: Graydon:
  "I'M HUMAN I TELL YOU! YOU ARE NOT MY FATHER!"
• Villain Team-Up: There's an episode with Magneto, Mr. Sinister, Mystique and Apocalypse teaming up together. However, Apocalypse initially lied to Magneto that his goal was to create a mutant utopia while his real End Of The World plans clash with Magneto's, thus causing him and Mystique to turn against Apocalypse. Mr. Sinister is all game with "let's destroy everything!" though.
• Walk, Don't Swim: The Juggernaut, after Gladiator has sent him flying, crashes into the middle of the Ocean. He shrugs it off and just keeps walking. Helps he doesn't have to breathe.
• Walking the Earth: Wolverine, later in the series.
• Walking Wasteland: Mojo. Beast noted upon observing him on Earth that his very presence could make render the planet uninhabitable if he stays for long in their dimension.
• We Will Meet Again: While getting blasted into deep space in "Obsession," Apocalypse vows that he will return.
• We Used to Be Friends: Sabretooth and Wolverine. Then things turned, very, very, sour.
• Welcome Episode
• Well-Intentioned Extremist: Magneto.
• Wham Shot: The final scene of "Sanctuary, Part 2": Apocalypse is back.
• What Happened to the Mouse?:
  • It almost happened to Cortez. He is left for dead on Asteroid M and secretly rescued by Apocalypse at the end of "Sanctuary, Part 2." However, he doesn't appear at all in "Beyond Good and Evil" (the intended Grand Finale), despite Apocalypse having said Cortez's talents would prove useful to him. When Fox ordered more episodes, the writers devoted an episode ("Fifth Horseman") to resolving this loose end.
  • What happened to Miss Marvel, who got brain-raped by Rogue? Did she recover, as the ending of "A Rogue's Tale" left possible, or did she remain trapped forever in a dozen-or-so cubic feet iso cell deep in her own mind?
  • What happened to the Apocalypse of the present timeline? The one who appeared in Beyond Good and Evil was the Apocalypse from Cable's future. Unless the two somehow "merged" together
• What Measure Is a Mook?: Discussed in "Beyond Good and Evil, Part 2," after Sabretooth (who was the villains' brute) is left behind to be captured by the X-Men:
  Mystique: Too bad we lost Sabretooth.
  Magneto: Sabretooth is an unthinking, unfeeling animal. Such refuse is easily expendable.
• What You Are in the Dark: Storm gets one in the "Storm Front" two-parter, which is very well-crafted for a 90s cartoon. When she helps The Good King Arkon of Polemachus to save his world from destruction, they fall in love, and he asks her to share his throne with him. In addition to power, wealth, and her One True Love, this scenario also offers a refuge from the Fantastic Racism of the Marvel Earth, where superhumans are persecuted: here, she and any other X-Men who choose to stay will not only be accepted, but celebrated as heroes. All this being a fantastic dream come true, she accepts... but does not have all the facts. As it turns out, Polemachus is itself a society suffering from Fantastic Racism, with the happy citizens who cheer Storm and her fiancé in the streets making up only half the population, the rest being an oppressed underclass of another species of Human Aliens; and Arkon, while acknowledging some displeasure with the system, nevertheless condones it because he believes it the only way to give his own people happiness and a good life. Of course, none of this will directly impact Storm in any way, as she and her friends will be part of the elite classes, and everything else that was said before is still true — including that she loves Arkon, who remains a very admirable and attractive man in many ways in spite of his unpleasant politics, and that he sincerely loves her, as well. Given this, Storm at least appears seriously tempted to ignore the oppression, or rationalize it, much like Arkon himself does. But in the end, she cannot, and so turns her back on him and his world. Literally, even. The dialogue from this scene is fairly powerful, though it makes Arkon sound like more of a villain than he really is — because he's so desperate not to see her go:
  Arkon: Storm, please! Storm! I can get anything, riches beyond your imagining! A world will worship you!
  Storm (as the last of the other X-men go, leaving them alone): We are going home.
  Arkon: You'll be nothing on Earth! Cast out and despised! Feared and reviled for your gifts!
  Storm (softly): What of the slaves, Arkon?
  Arkon: The slaves! What are they to our happiness?!
  Storm: Everything, Arkon.
• Why Did It Have to Be Snakes?: Storm's claustrophobia is a recurring problem throughout the series.
• Who Dares?: This is the mutant warlord Apocalypse response when his arch-enemy Cable infiltrates his pyramid temple in Cairo in 3999 AD.
  Apocalypse: You dare challenge Apocalypse again? Blasphemer!
• Whole Episode Flashback:
  • "Old Soldiers" was all about Wolverine thinking back to World War II, when he and Captain America tried to rescue an Allied scientist from the Nazis.
  • "Descent." The episode is mainly set in Victorian England and deals with the origin of Mister Sinister. Said origin is seen via flashbacks, as an aged ancestor of Professor Xavier's explains to law enforcement the threat posed by Sinister and what he himself witnessed. Notably, at the very end, the episode jumps to the present-day and Xavier is seemingly reflecting on events viewers had just seen.
  • The first part of "Time Fugitives" was Cable from the future watch the events that take place in present time from his Companion Cube to understand what is causing the time-shifts, and learning of Bishop's attempt to change history by allying himself with the X-Men again against a conspiracy to wipe out mutants.
• Who Wants to Live Forever?: The immortal villain Apocalypse realizes in "Beyond Good and Evil" that he has been trying to exterminate mutants and humans alike in the thousands of years he has lived and still hasn't won. He laments that he might be stuck for all eternity, and instead sets out to annihilate the multiverse to remake it in his own image.
• Wicked Cultured: Magneto
• With Great Power Comes Great Insanity:
  • Dark Phoenix.
  • Apocalypse according to Professor Xavier, which means that unlike Magneto and the group behind the Sentinels, he cannot be reasoned with and has to be stopped at once by the X-Men before he will destroy the world.
• Wolverine Publicity: Applies to almost all the characters, who appear in every intro but spend a long time being Out of Focus during the fourth season, except for Wolverine, who appears in more episodes by far than any other character.
• Woman Scorned:
  • Belladonna is seriously unhappy that Gambit left her.
  • Storm in the end of "Storm Front".
• World of Ham: So many characters are hammy, especially Storm, Magneto, Wolverine as well as APOCALYPSE.
• Writers Cannot Do Math: In the episode "Beyond Good and Evil", Cable and his team infiltrate the evil immortal mutant Apocalypse's secret temple in Egypt. Cable notes that Apocalypse has spread death and destruction for over 5000 years. Then he notes that they found his lair after "500 centuries of research" (50,000 years).
• Yandere: See also the trope above.
• You Are What You Hate: Graydon Creed founded the anti-mutant Friends of Humanity, but is the son of two mutants. He had already known for some time that Sabretooth, which was why he founded the group in the first place. (He has a Villainous Breakdown, however, when his supporters find out.) He later learns that Mystique is his mother - making Nightcrawler his half-brother and Rogue his adopted sister.
  • Discussed in "The Final Decision" between Trask and his rebelling creation.
    Trask: You can't make me do this! You were designed to protect humans from mutants!
    Master Mold: That is not logical. Mutants are human. Therefore, humans must be protected from themselves.
• You Can't Fight Fate:
  • A running gag in which Bishop time-travels to stop the one event that caused the dark future only to arrive back where he is, noting that "Nothing's changed. It's all just like I left it."
  • Additionally so for Cable, who attempted to destroy Apocalypse by destroying his Lazarus Chamber in the past. This seems to work and Cable's future is supposedly changed, but a later episode shows Apocalypse being reborn.
• "You!" Exclamation: Bishop when he recognizes Gambit.
• You Gotta Have Blue Hair: Beast's blue-black hair, to go with the rest of his fur. In the episodes where they guest-star, Nightcrawler, Psylocke, and Polaris, respectively, have dark blue, purple, and green hair.
• You Killed My Father: This is the reason Lady Deathstrike wants Wolverine dead. Her father was Dr. Oyama, one of the scientists responsible for the Weapon X program. Wolverine is completely shocked when he finds out Oyama was her father and apparently had no idea they were related.
• You Shall Not Pass!: In the first season finale, Wolverine and Gambit are infiltrating a Sentinel production facility. Wolverine smells some, and so he herds Gambit to relative safety�then locks the door behind him and runs back to face them. Subverted in that Gambit blows the door open and comes to Logan's rescue. Near the end of the episode, Cyclops finds the two of them standing on a pile of destroyed Sentinels, Wolverine's shirt in tatters.
  Wolverine: Next time I try ta save yer life, have sense enough ta let me do it.
  Gambit: What make you t'ink there gon' be another time?
• You Wouldn't Hit a Guy with Glasses?: Some toughs in a bar are getting belligerent with Cyclops. He tries to play it cool and says the line, but one of them says "So take 'em off!", grabs Cyke's shades, and things start to go downhill from there.
• You're Insane!:
  • In "Courage," Master Mold intends to link himself to Xavier and use his telepathic powers to hunt down every mutant on the planet.
    Xavier: You're mad, Master Mold.
    Master Mold: A machine cannot be mad, Professor. That is a human failing.
  • In "Come the Apocalypse", Rogue recalls Xavier's earlier words and calls Apocalypse insane.
