Code Name: Cyclops
Real Name: Scott Summers
Voiced by Kirby Morrow
"No, we're the X-Men. We're not kids anymore. You trained us, Wolverine, and you know something? We're good. Very good."The leader of Professor Xavier's students. A mutant who shoots high-intensity beams from his eyes. Unfortunately for him, he can never shut this power off so he must always wear special visors or glasses made of ruby-quartz. Due to having a strong sense of morals and drive to be the leader, Scott can sometimes come off as a "boy scout" or "do-gooder". But he also has an extremely competitive side and tries hard to hold his temper in check, which can sometimes get the better of him. In contrast to his reputation for being stiff, he surprisingly shows a good sense of humor. During the series, Scott reunited with his brother Alex, who he thought died in the plane crash both were involved in.
- Adaptation Personality Change: Contrasting with many other incarnations, this version of Scott is not an aloof, doubtful, stiff loner, but a confident and self-assured leader with a much more extroverted personality and more open sense of humor.
- Adaptational Nice Guy: Compared to his — shall we say, controversial comic-book counterpart, Scott is kind to his friends, likable, and much more unambiguously heroic in this series.
- Alliterative Name: Scott Summers.
- Arch-Enemy: Avalanche. Even when he attempts a Heel–Face Turn, Cyclops constantly has issues with him, which Lance is all too happy to provoke.
- Beware the Nice Ones: Reliable and level-headed when calm, but piss him off and watch out!Juggernaut: (taking a full blast from Cyclops' visor) You think that can stop me? I'm RAW POWER!!Cyclops: You want it raw, tough guy, then take it RAW!! (takes off his visor and unleashes his unfiltered, unrestrained optic blast)
- Big Brother Instinct:
- Very protective of his long-lost little brother, Alex.
- Additionally, he's protective of the younger mutants, particularly Kurt.
- Big Brother Mentor: To Kurt.
- The Captain: And a badass one at that. This is easily one of Scott's most badass depictions yet, especially compared to his less experienced teammates .
- Chick Magnet: Attracted the affections of Rogue, Taryn and Jean. Even Kitty was seen gushing over him.
- Cool Shades: As usual, still has to wear ruby-quartz lenses to control his powers. These come in the form of sunglasses in his civilian outfit.
- Decomposite Character: His usual role from the comics and other animated adaptations of being the first mutant recruited into the X-Men is given to Wolverine.
- Eye Beams: It's Cyclops, people. He's synonymous with the optic blast.
- The Hero: He's the leader of the main X-Men team, as always.
- Heroes Want Redheads: With Jean.
- Heterosexual Life-Partners: With Kurt. Fridge Brilliance kicks in when you realize how after he was separated from his brother, Alex, Kurt ends up fulfilling this role for him.
- Ink-Suit Actor: If you take away the shades, Scott closely resembles his voice actor.
- Mr. Fanservice: Tall, Dark, and Handsome, with plenty of Clothing Damage to boot.
- Mugging the Monster/Bullying a Dragon: For some reason, everyone wants a piece of Cyke, especially Duncan and Avalanche, and especially when the former finds out why he wears those shades.
- Nice Guy: Less aloof than usual portrayals and surprisingly affable.
- Official Couple: He ends up with Jean.
- Power Incontinence: Again, it's Cyclops. It's inherent to the character.
- Sexy Spectacles: His pretty boy design flirts with the idea. It's one of the reasons why girls fawn over him.He's, like, totally Hollywood in those shades!
- Ship Tease: Rogue had a crush on Scott and he might have had some feelings for her, though he was mostly Oblivious to Love. But see Official Couple.
- Shirtless Scene: Scott's clothing is made of much weaker materials than everyone else apparently.
- Sickeningly Sweethearts: With Jean. Once they finally get together, Kurt and Kitty gleefully mock them as being this.Kurt: Jean, darling, please accept this croissant as a symbol of my love!Kitty: Oh, Scott, you have such a way with pastry!
- Sunglasses at Night: Don't switch the blade on the guy in shades, oh no!
- Wave Motion Gun: Pulls one off against The Juggernaut by tearing off his visor and opening his eyes as wide as he can. Sure, this is The Juggernaut and it only lasts a while, but it takes out huge chunks of the surrounding area.
- Workaholic: Played for Laughs: Scott LOVES Danger Room Simulations, and is happy to suggest them as a possible group activity at two in the morning.
Code Name: Unknown
Real Name: Jean Grey
Voiced by Venus Terzo
"Now most of you have children, and you love them for who they are—not for what they can, or can’t do. There is a chance that one of them will have an advanced X gene, and as they grow older they will be considered mutants. You will love them anyway. But people will hate them. And people will want to hurt them. You will hope for the day that your child can live in a safe world. Well that world must begin now. With you. By allowing mutants to attend public school."Jean was the most popular of the X-Men who attended Bayville High. Beautiful, athletic, and smart, she seemed to not have the problems the others faced trying to fit in and be normal. But her growing powers made her extremely insecure and showed she had her own burdens to bear. And she was ultimately shunned by her former friends when revealed to be a mutant. Jean dated Duncan Matthews for the first two seasons, but later fell for Scott, who had secretly loved her from afar. Jean also has a very close father-and-daughter type relationship with Professor Xavier.
- Academic Athlete: She's shown to excel in various sports like soccer, track, and basketball, and she's mentioned to have been accepted by several universities to study genetics.
- The Ace: Jean is one of the most powerful mutants at the Institute and she has excellent control over her abilities. She is also intelligent, strong-willed, very well-liked, and a naturally gifted athlete.
- Action Girl: Jean is highly capable of defending herself and others whenever the time calls for it.
- Bare Your Midriff: All three of Jean's civvies outfits.
- Battle Couple: With Cyclops, combining his optic blasts with her potent psychic abilities.
- Clingy Jealous Girl: Of the passive-aggressive kind. She wasn't outwardly mean to Taryn or Rogue when in the jealous mood, but being a Tsundere she tended to take it on Scott instead via phone Passive-Aggressive Kombat.
- Code Name: Averted. She uses her real name. This is lampshaded by Kurt in the tie-in comics.
- Cool Big Sis: To Kitty and the New Mutant girls.
- Dude Magnet: Jean has had a total of four guys that have taken an interest in her at some point throughout the series. Just ask Scott, Duncan, Fred and Lucas.
- Fiery Redhead: Exemplified in this statement:Principal Kelly: A fiery temper? That's a dangerous combination with your kind of powers.
- Girly Bruiser: Jean is girly and well-mannered, but also quite the badass with her psionic powers.
- Impossible Hourglass Figure: Nice, uh, pants, Jean.
- Light Feminine and Dark Feminine: Along with Kitty, both are the light to Rogue's dark.
- Mind over Matter: Her powers are telepathy and telekinesis. She often uses her telekinesis to lift herself and others, giving her the ability of levitation and flight. She also uses her telekinesis to create durable shields and energy blasts.
- Moral Guardians: Compare Jean to Cyclops in season one's Survival of the Fittest. Both the Brotherhood and X-Men competed to get to the top of a mountain and place a flag before the other team. The catch was neither team could use their powers. But Scott had no problem cheating and using his powers after seeing Avalanche cheat. Jean though was quick to point out that the X-Men should be above such things and stick to the rules. Interesting that neither Scott or Jean were portrayed in a positive light here with Jean being shown as slightly overbearing and self serving.
- Power Incontinence: "Power Surge" is dedicated to have her go through this.
- Red Oni, Blue Oni: The blue to Rogue's red.
- Redhead In Green: She wears a black X-Men uniform with a bright green stripe down the front and back.
- Sickeningly Sweethearts: With Scott. Once they finally get together, Kurt and Kitty gleefully mock them as being this:Kurt: Jean, darling, please accept this croissant as a symbol of my love!
Kitty: Oh, Scott, you have such a way with pastry!
- Significant Green-Eyed Redhead: Has red hair and green eyes.
- Spoiled Sweet: She possesses everything that can make a girl the Alpha Bitch: beauty, popularity, and a jock boyfriend. Instead, she’s nice and willing to help anyone.
- Straw Feminist: This comes up during Walk on the Wild Side and is never really touched on again. She calls Scott out on trying to help and bitches at Duncan for buying tickets to a dance, when it's supposed to be the girl who asks the guy out, while complaining about always feeling like she's treated as the weaker sex.
- This was kind of done pretty badly because Jean takes an obvious joke Scott makes very personally, and keeps raging even when he apologizes and obviously regrets what he said.
Code Name: Nightcrawler
Real Name: Kurt Wagner
Voiced by Brad Swaile
"Chicks dig the fuzzy dude!"Nightcrawler is a blue, furry mutant whose power is the ability to teleport. He uses a holographic image inducer in public to appear as a normal teenage boy. Nightcrawler is the biological son of Mystique, who dropped/abandoned him a long time ago. They don't get along.In contrast to his demonic appearance, Kurt is kind, fun loving, and a loyal friend. But there also is a sense of sadness about him as he longs to be accepted by the world outside despite his appearance.
- Age Lift: Unlike the rest of his peers in the series, Kurt was already an adult (like Ororo and Logan) when he joined the X-Men in the comics.
- Amazing Technicolor Population: Blue. Just like his mother Mystique. Well, technically he has blue fur. But he's a mutant so it still counts.
- Arch-Enemy: Toad.
- Beast and Beauty: Kurt and Amanda.
- Berserk Button:
- Don't pull his tail.
- Also don't steal his Image Inducer. He completely flips out when Toad does it.
- Big Eater: Apparently the price of 'porting.
- Cute Monster Boy: In this version, Kurt is an elfin cutie pie with blue fur, a tail, pointed ears and fangs.
- Dark Is Not Evil: Don't be fooled by his demonic appearance, he's one of the sweetest guys around.
- Freakiness Shame: While Kurt is ashamed of his appearance, he soon seems to become more relaxed about it around other mutants. He's still afraid of letting normal people see his true face, constantly wearing a device that projects a hologram around him to make him look like a normal person in public, but this trope is invoked when Amanda Sefton convinces him to turn off his image inducer as she like his real self.
- Freaky Is Cool: Kurt's girlfriend Amanda isn't bothered at all by his true appearance.
- Fun Personified: He loves to party.
- Gratuitous German: Kurt originally comes from Germany and since he’s one of the main characters, this longtime trait is a given trope for his character. There are a few times when he slips German into his sentences, but he stops this early in the first season.
- Handy Feet: His feet are shaped very much like his hands and are just as dexterous as shown when he was piloting the X-Jet with just his feet.
- Happily Adopted: Played with, as Kurt loves his adoptive parents dearly and wouldn't trade them for the world, but as time goes on he shows a little too much interest in his birth parent and his origin. However, at the end he's shown to be unwilling to establish any kind of relationship with Mystique.
- Heterosexual Life-Partners: With Scott.
- Hide Your Otherness: In order for him to attend Bayville High, Kurt uses an image inducer to go out in public looking like a normal dark-haired, light-skinned teenage boy.
- Hologram: Kurt's normal Bayville High appearance is nothing more than a hologram. Deconstructed at the beginning of season 3 when it turns out that Kurt is the only Xavier Institute student with his cover still intact thanks to his hologram inducer.
- In-Series Nickname: Fuzzy Blue Elf.
- In the Hood: In the first episode, he wears a trenchcoat with a hood to hide his demonic appearance.
- The Lancer: To Scott.
- Nice Guy: One of the nicest.
- Platonic Life-Partners: With Kitty.
- Pointy Ears: Given his overall demonic appearance it's something of a surprise he doesn't have horns.
- Poirot Speak: Kurt frequently uses German words and phrases in his speech.
- Pretty Boy: Kurt is very attractive with or without his disguise, although he falls more on the "cute" side. With his elfin features, they reflect his adorkable personality, and the impression Nightcrawler leaves on viewers is that he's a cute blue elf rather than a freaky blue demon.
- Red Is Heroic: Like his comic counterpart, Kurt's outfit includes a significant amount of red.
- Sad Clown: Sometimes, not nearly as often as the Fan Dumb would have you think. He gets his fair share of angst, but by the next episode he'll be back to making jokes and acting happily.
- Tele-Frag: When Scarlet Witch messes up his powers and causes him to teleport into a sign. The sign is pushed apart by Nightcrawler appearing in the middle of it. What would happen if it had been a person is left to the imagination.
- Teleporter Accident: Forge tries to extend the range of Nightcrawler's teleportation, and ends up creating rifts to the hell-like dimension Nightcrawler uses to move from place to place. Needless to say, the inhabitants get out.
- Ugly Cute: "Ugly" in-universe (He's repeatedly been compared to a big blue rat), freaking adorable to the fans (and his girlfriend).
- Wall Crawling: He can stick to walls. He's even called "Wall Crawler" at one point.
- You Gotta Have Blue Hair: Like Wolverine, the animators make Kurt’s hair dark blue instead of black.
Code Name: Rogue
Real name: Unknown (named Anna Marie in the mainstream comics)
Voiced by Meghan Black
"Me and Miss Popularity there are worlds apart, galaxies, but then I realized something. She would do the same thing for me."Rogue is a mysterious mutant who absorbs the memories and abilities of others through touch. Due to her powers, Rogue has become withdrawn, bitter, anti-social, and sullen. Only after learning to trust the other X-Men, does she begin to open up. Rogue is Mystique's adopted daughter, but turns her back on Mystique after learning that she was only using her and joins the X-Men. She develops a massive crush on Cyclops, but later accepts that Scott loves Jean and not her.
- Action Girl: She has mutant powers and she does use them occasionally but relies more on her combat skills to fight enemies.
- Adaptation Personality Change: Rogue of the comics and other adaptations is more of a Southern Belle. The cartoon presents her as an awkward Deadpan Snarker.
- Adaptational Dye Job: Her eyes are generally green in the comics, but they're portrayed as grey in the show.
- All Love Is Unrequited: Her love for Cyclops can never be returned.
- Word of God from series writer Frank Puar says that though Rogue lost to Jean during their teen years, the small glimpse of the future team from the series finale showed subtle hints that after Jean's disastrous contact with the Phoenix Force and subsequent death, Rogue would finally be able to confess her feelings for Scott and they would become a couple
- Same with Cody, the star football player from her hometown in her debut episode. The one who had been staring at her for a week before being brave enough to ask her for a dance.
- American Accents: Dixie
- Anti-Villain: Was this when she was a member of the Brotherhood.
- Badass Longcoat: She wears a brown coat◊ every now and then.
- Bare Your Midriff: A good majority of her outfits, especially her Season 1 civilian outfit. Given her powers, she manages to pull it off by wearing a see-through top over the outfit sometimes.
- Blessed with Suck: Her powers mean she can never touch anyone without risking their lives. Significantly less so in this adaptation; she often uses her powers to knock out one opponent, and then proceeds to use their powers to take care of the rest of them. Or if one of her friends is knocked out anyway, she takes their powers as an extra boost to the group's fighting strength. She definitely uses her power much more liberally not to mention more effectively than in other media portrayls.
- Clothing Damage: Somewhat justified. In the Season 3 two-parter finale, Rogue is hit head-on by a massive fire blast from Pyro. Having just absorbed Colossus' metal skin power, she comes out of it unharmed. Her clothes, however, are burned off except for the obvious necessary bits and some extra scraps.
- Cool Big Sis: According to Kurt.
- Deadpan Snarker: As a rather moody character, she's quick to throw some sarcasm out every now and then.
- Distracted by the Sexy: She's so taken with Gambit when she first meets him that she doesn't realize he's given her a card that's about to explode.
- Energy Absorption: If her skin touches anyone else's then she'll absorb energy as well as their memories and abilities. The longer she holds on, the more she absorbs.
- Fights Like a Normal: Due to the nature of her power, most Danger Room scenes have her instead use basic training and martial arts to deal with the robotic threats and use her powers sporadically. Shown off in Cajun Spice, where she uses her power for mind reading only and mostly takes out the Rippers with just outmatching them in fighting skills.
- Goth: A huge departure from her Southern Belle comic persona. And it proved to be quite popular. Some Comic writers (notably Grant Morrison) wanted to Canon Immigrant this, but never got the chance to. Instead it appears X-23 has absorbed this trait when adapted into the Comics.
- Green-Eyed Monster: Rogue shows some jealousy toward Jean, possibly due to her own power's drawback and Jean seeming to be perfect in every way. This becomes clear in season two's Power Surge where Jean can telepathically hear Rogue snark on her for winning an award, and later for believing Professor Xavier gives Jean preferential treatment. Knowing that Scott, who she has a crush on, really loves Jean doesn't help either. At the end, she acknowledges that for all their differences, Jean does care for her.
- Grey Eyes: She has these in which they represent her cynical and reclusive nature.
- Has Two Mommies: Both Mystique (adoptive) and Destiny (foster).
- Heel–Face Turn: She first joined the Brotherhood before joining the X-Men.
- Hopeless Suitor: For Scott since he only has eyes for Jean.
- Kiss of Death: She did this to Gambit in "Dark Horizon" to absorb his powers, though it only knocks him out.
- Light Feminine and Dark Feminine: The dark to Jean and Kitty's light.
- Most Common Superpower: Again, it's Rogue. (Not to the levels seen in the comics. Rogue is realistically proportioned here, but still more ample than the other X-Men.)
- Mundane Utility: She once used her power so she could dance like Kitty.
- No Name Given: She's referred to as 'a rogue' by Xavier in her origin episode, then she expresses a lack of memory. Since then, her name was never revealed in the show, and she was only referred to as Rogue. Many have taken to calling her Anna Marie, her current comic name, but it's more of a fanon thing right now.
- Odd Friendship: With Kitty. The girls have nothing in common, but get along great. Well, they eventually do, earlier episodes showed them as not being able to stand each other.
- Only One Name: Just Rogue. One wonders how that worked at school.
- Personality Powers: Played straight in this version. She's a gloomy, withdrawn goth with an uncontrollable death touch.
- Promoted to Love Interest: Her comics' counterpart never had romantic feelings for Scott.
- Red Oni, Blue Oni: The red to Jean's blue.
- Redhead In Green: Rogue has auburn hair but she still qualifies. In one of her civvies outfits, she wears a green mesh top over her black halter. And her X-Men battle uniform has a green armor platelet that goes over her chest area.
- The Resenter: A little bit, for Jean. During the first episode of season 2, Jean catches Rogue getting chided by the Professor, with Rogue thinking to herself the Professor would never treat Jean the same way.
- Romantic Two-Girl Friendship: Rogue made quick best friends with Risty Wilde, a girl from Manchester, England. They seemed to have a lot in common and some fans were getting some Schoolgirl Lesbians vibes from the two. That came to a halt when we learned Risty was actually her mother Mystique in disguise.
- Shapeshifter Identity Crisis: When her powers become unstable all the personality's she's ever absorbed begin to surface and with Mystique's powers she takes the form of whatever person she has previously been in contact with.
- Ship Tease: Beside the aforementioned crush on Scott, in the later seasons she had one full episode of blatant teases with Gambit, plus scattered moments in other episodes.
- Though, according to the character designer and occasional director of the series, they kept this to a minimum because a lot of the writing team shipped Scott and Rogue.
- Sixth Ranger: She became the last member to join the original team before the recruits appeared.
- Skunk Stripe: Not really explained how or why she has those white bangs. Whether she was born with it or she dyed them to go with her gothic style, we can only assume. She's even called "skunk head" by some punks in an episode.
- Wakeup Makeup: Rogue is never seen without her makeup. Even when Avalanche pushed her into a pool, or when she just steps out of the shower, her make-up is completely intact. Though there is one episode in season 4, "Cajun Spice," where Rogue falls into a lake and comes out makeup-free.
Code Name: Shadowcat
Real Name: Katherine 'Kitty' Pryde
Voiced by Maggie Blue O'Hara
"I don't have any gifts, just a curse."A mutant from Northbrook, Illinois whose ability allows her to become intangible. Shadowcat is the youngest member of the team and is characterized by her upbeat nature and cheerfulness. She usually pals around with Nightcrawler since they are about the same age. Her on-again off-again romance with Avalanche was a sub-plot that continued through all four seasons. She first develops a crush on him while still in school, but it turned out he was only using her to steal test answers. Later, even though they are on opposite teams, Lance saves her life and her opinion of him changes. They date for a while, but their differences break them up, before ultimately reigniting their romantic relationship after the fight against Apocalypse.
- Adaptational Dye Job: Her eyes are generally portrayed as brown/hazel in the comics, but here they're a light blue.
- Affectionate Nickname: "Kitty" is a nickname to begin with. (Her real first name is Katherine.)
- Avalanche calls her "Pretty Kitty" and "Kit-Kat", alternatively.
- Wolverine calls her "Half-Pint".
- Spyke calls her "K-Girl".
- Age Lift: Subverted. She's around the same age as as her original comic book incarnation, but she was initially the youngest member of the team when she joined in the comics, while her teammates in the show are about as young as she is (meaning that the Tagalong Kid aspect of her character is completely dropped).
- All Girls Want Bad Boys: Somewhat subverted in that Kitty was attracted to the good person inside of Lance, and wasn't super thrilled when he acted like an asshole. Although to a 15-year-old girl being pursued by an older and handsome bad boy wasn't exactly a turn-off.
- Bare Your Midriff: Two of her civvies outfits shows off her stomach. Also her Bayville Sirens outfit.
- Cute Clumsy Girl: The only class she doesn't ace is gym.
- Dating Catwoman: With Avalanche.
- Ditzy Genius: Although she speaks like a Valley Girl, she's quite smart. In her first episode, the Girl Posse claim she's acing all of her classes except PE. In another episode she and Evan figure out how Forge's machine works simply by examining it. And she also demonstrates knowledge of how to short out a helicopter's weapon system without knocking down the craft.
- Drives Like Crazy: Her driving even scares Wolverine, due to her habit of phasing the car through obstacles. Scott was so scared that he stated he never wanted to ride a vehicle again.
- Girls Love Stuffed Animals: She's seen cuddling/sleeping with a stuffed, purple dragon, which is a reference to Lockheed, Kitty's pet dragon from the comics.
- Girly Bruiser: Has a Valley Girl personality but capable of kicking just as much ass as her teammates.
- I Just Want to Be Normal: At first. But she gets over it after a few episodes.
- Informed Judaism: The only evidence that she's Jewish is a scene of her lighting the menorah in her home in the Christmas Episode.
- Intangible Girl: She can phase through solid objects and even people. Amusingly in one episode she phases through Beast while brushing her teeth...and accidentally leaves the toothbrush inside him.
- Lethal Chef: Oh, yes. She gains this reputation after she uses Kurt as a guinea pig for her muffins. After a couple of batches, he bolts whenever she asks him to taste her cooking.
- Light Feminine and Dark Feminine: Along with Jean, both are the light to Rogue's dark.
- Morality Pet: Since season two on, definitely Lance's.
- Ms. Fanservice: A modest example, but she spends an episode or two clad in nothing but a swimsuit, so it's there in a "girl next door" kind of way.
- Naïve Newcomer: She definitely feels like a fish out of water when she first joins the X-Men, being particularly weirded out by Kurt's appearance at first.
- Official Couple: She gets back together with Lance in the last episode.
- Platonic Life-Partners: With Kurt.
- Plucky Girl: Although she's initially nervous on the X-Men, she demonstrates a lot of bravery and determination when the occasion calls for it.
- The Smart Girl: She can be a brainiac sometimes...
- Ship Tease: Occasionally with Evan. She's notably more affectionate to him than the other X-kids.
- Stuffed into a Locker: This happens to her in her debut episode, mostly as an excuse for Kitty to discover her ability to phase past solid objects. So naturally, this causes her to bump into Avalanche to kick off the plot.
- Teen Genius: A straight A student (although her intelligence was somewhat downplayed compared to other versions of Shadowcat).
- Valley Girl: Unlike her comic book counterpart. However, she stopped, like totally, after the first season. For sure.
- Walking Techbane: Like her comics counterpart, her powers can often cause machinery to malfunction if she phases through them.
Code Name: Wolverine
Real Name: Unknown, goes by Logan
Voiced by Scott McNeil
"We're definitely gonna need more instructors. An' maybe a couple of tanks."The X-Men's top fighter and chief drill instructor to the students. His keen senses help him track down adversaries and alert him of danger ahead. His healing powers make him nearly impossible to defeat in a brawl. Adamantium claws are capable of shredding enemies and just about any inanimate object as well. His past is a mystery to everyone, including himself. It is a rather lengthy past as well because his healing factor has drastically slowed the aging of his body. He was already an adult by World War II. Unlike in other X-Men series, Wolverine plays a minor role in X-Men: Evolution and is more of a Papa Wolf than carousing badass.
- Adaptation Dye-Job: His superhero costume is colored orange and black in this series, whereas in the comics and the previous series along with the other animated adaptations, it was colored yellow and black.
- Adaptational Nice Guy:
- Due to the series' changes to certain character's ages, he never falls in love with teenage Jean Grey, and therefore never has the heated rivalry with Cyclops that is the cause for much of his Jerkass behavior in the comics (though the two did briefly have a leadership struggle).
- Also, while he always was fond of young mutant daughter figures, it would take decades of Character Development for him to be anywhere close to willing to play father figure with Storm and Xavier for an entire group of mutant children before any school for gifted youngsters or superhero team was properly established.
- Anime Hair: It actually bends backwards and up.
- Archenemy: With Sabretooth.
- Badass Biker: Logan owns two motorcycles and is often seen driving them. And just watch the beginning sequence of “Operation: Rebirth” where Wolverine being chased by the military in the woods on his motorcycle. Talk about badass!
- Badass Teacher: He's the students' chief drill instructor, and he kicks a lot of ass.
- Bash Brothers: With Captain America back in WWII, who he promises to one day find a cure for his recovery.
- Bruiser with a Soft Center: He gradually warms up to Kitty and Kurt nicknaming them "Half-pint" and "Elf" respectively.
- Composite Character: He has Cyclops' usual role from the comics and other animated adaptations of being the first X-Man.
- Cool Old Guy: The guy was around helping Captain America in WWII.
- Deadpan Snarker: To the students.
- Defusing the Tyke Bomb: Whenever the students are having issues with themselves or their powers, he's there to help make sense of it since he's been there himself. Most notably to Rogue.
- Drill Sergeant Nasty: Can be at times; see Training from Hell below.
- Hair Color Dissonance: Technically, his hair is supposed to be black, but with the way the animation is, it looks more dark blue than black.
- Hair-Trigger Temper: Downplayed. Despite his temper and violent attributions, he does try to control them.
- Healing Factor: Due to the nature of most children's shows, this can't be shown that effectively. But it's better shown here when Wolverine’s shown to have broken his legs from a helicopter jump, and later on in Season 4 when he falls out of a plane.
- I Work Alone: Downplayed. Although he prefers to be alone, he does enjoy the company of those he likes.
- Intergenerational Friendship: With Kitty and Rogue.
- Mysterious Past: Some episodes go into his past... a little.
- The Nose Knows: His tracking mutant ability.
- Opposite-Sex Clone: X-23
- Papa Wolf: Hurt any of his X-Men at your own risk. Especially Kitty and X-23.
- Parental Substitute: To X-23. Even though she's basically his Opposite Gender Clone, he treats her like he would with his own daughter.
- Training from Hell: This trope gets first deconstructed, and then reconstructed - in the first X-23 episode, it's established that he can be pretty harsh with training the younger X-Men-to-be, to the point that Rogue wouldn't admit she'd gotten better (after the last episode's events) to avoid it. After his experience with the aforementioned Tykebomb, he loosens up because "Sometimes you gotta let kids just be kids". He realizes that pushing teenagers too far in training is detrimental, and he eases up by the end. Contains hilarity in that Rogue of all people was pretending to still be sick in an effort to evade his training session.
- True Companions: In their first scene together you can tell just how much he and Charles trust each other, and through the whole series they remain good confidants to each other.
- Undying Loyalty: To Charles and his school.
Code Name: Storm
Real Name: Ororo Munroe
Voiced by Kirsten Williamson
"I'm a weather-witch, not a snow plow. I'm doing the best I can."One of Professor Xavier's top teachers, Storm is seen as a role model by the students. She is also one of the most powerful mutants alive due to her ability to manipulate the weather. One of her few weaknesses is her claustrophobia which was explored in her one spotlight episode African Storm.
- Action Girl: Due to being an adult in contrast to the rest of the teenagers, she's quite powerful.
- Badass Teacher: She's not shown teaching that much, but she's suitably badass.
- Blow You Away: She can manipulate the winds to great effect.
- Brainwashed and Crazy: She becomes one of Apocalypse's Horsemen.
- Claustrophobia: As in the comics, she's got a great fear of confined spaces. One Danger Room simulation had her trapped in a tight box and she freaked out.
- Combat Stilettos: She has these on in both of her series and post-series costumes, but they're a non-issue for her since she's often seen hovering or flying.
- Cool Aunt: To Evan. He outright calls her this in his video project.
- Dark-Skinned Blond: Though her hair is white, and given a Hand Wave by saying that it's a distinguishing trait of her people.
- A Day in the Limelight: Her spotlight episode, "African Storm".
- Flight: One of the few characters that can fly in this X-Men Universe.
- Impossible Hourglass Figure combined with She's Got Legs: Word of God from the guy who designed the characters, Storm has very long shapely legs and curvy hips.
- Making a Splash: Can produce rain, of course.
Code Name: Beast
Real Name: Hank McCoy
Voiced by Michael Kopsa
"I can see now that teaching mutants will require entirely different skills."Hank McCoy was a popular teacher at Bayville High who held a dark secret. His mutation gave him a burly physique with large hands and feet and unparalleled agility, but also a feral side to his mind. After school hours, he worked on a serum he hoped would stop his primal regressions when simply reciting Shakespeare wasn't enough to keep him focused. But unfortunately his beastly side was set free by an attempt to make a better serum, turning him into a blue furred beast. He damaged the school, also threatening Principal Kelly in an uncontrollable rage. The X-Men eventually were able to locate and subdue him. Soon the rage subsided, but life would never be the same. His rampage at the school and his drastic and permanent change in physical appearance would make any public appearance too startling for a general population unaware of the mutants among them. Hank remained at the Xavier Institute as a teacher for the New Recruits. Similar to Wolverine and Storm, he is more of a bit player due to the focus being on the students.
- Age Lift: In the comics, he was around the same age as Scott and Jean when he first arrived at Xavier's School. Here, he's a middle-aged teacher while Scott and Jean are high school students in their late teens.
- Cool Teacher: In the eyes of the New Mutants, in stark contrast to Wolverine Stern Teacher or Jean and Scott's Politically Motivated Teacher mentality.
- Establishing Character Moment: His first scene after entering the classroom in Season 2 is to ask if any of the students want to create a stink bomb, right after Lance and Kitty were talking about one. A later scene also has him kick Duncan off the football team immediately after he rams into Scott during a dash.
- Freakiness Shame: Like with Kurt, Hank feels like a freak at times after trying to cure himself, despite he still retains his mind. Even when Xavier suggested to give him a holographic inducer, Hank doesn't want to reenter the world. He does get over it after a researcher capture Hank Mc Coy after mistaking him for Bigfoot. When he finds out that Mc Coy is intelligent, he is amazed and does his best to save him from overzealous hunters. Since then, never had much of a problem of his appearance.
- Gentle Giant: Sure he looks big and scary, but he has the temperament of a teddy bear.
Code Name: Professor X
Real Name: Charles Xavier
Voiced by David Kaye
"You know, handling defeat is as much mark of your character as coming home the victor. And from what I see, this was a lesson, apparently, much needed."The world's most powerful telepath and founder of the X-Men. His goal is to maintain a peaceful co-existence between humans and mutants. He created a school which trains mutants to use their powers responsibly and discreetly in order to prevent panic from the general human population. This philosophy puts him at odds with mutants such as Magneto who believe mutants should be dominating humanity rather than hiding from it.
- Big Good: As per the franchise's norm, he's the Big Good to contrast with Magneto's Big Bad.
- Brainwashed and Crazy: Like Storm, he's captured by Apocalypse and turned into one of his Horsemen.
- Comic-Book Fantasy Casting: As with every version of Xavier since the first X-Men, he sounds a lot like Patrick Stewart, though this version sounds like a fusion of Stewart and Sean Connery.
- Friendly Enemy: How Xavier sees Magneto, although their friendship is not as emphasized as in other portrayals.
- Gadgeteer Genius: He's responsible for the creation of technological achievements such as the mutant-tracking computer Cerebro, the Danger Room, and the Juggernaut's holding cell.
- Mind over Manners: He often prefers to "ask" before he reads your mind.
- Non-Action Guy: Justified since he's wheelchair-bound. Not that it impedes his telepathic powers. He could perform Mind Rape and the like, making him a destructive force, if he wasn't so moral.
- Not So Above It All: Despite being generally concerned for the larger picture and being a stern but fair father figure they can all trust, it doesn't stop him from reprogramming Nightcrawler's image inducer to make him look like a girl after he broke it.
- Parental Neglect: Subverted in regards to David/Legion. He didn't mean to be neglectful, as he didn't know the kid existed!
- Psychic Powers: One of the most powerful psychics in the franchise (the comics and cartoons).
- Team Dad: Several of the X-Men view him as their father figure, especially Scott and Jean.
- Telepathy: With his formidable psychic powers, Xavier is one of the most powerful and foremost telepaths on the planet.
New Mutants/New Recruits
Code Name: Iceman
Real Name: Robert 'Bobby' Drake
Voiced by Andrew Francis
"Hey! Did you see? Were you watching? This time it took me almost twice as long to crash and burn."The unofficial leader of the 'baby' group the New Recruits. Bobby joined, along with his team, during the break between season 1 and 2 and appears mostly in B-plots and eventually becomes the Sixth Ranger once Spyke leaves the main team.
- Brilliant, but Lazy: He's shown in the few times he gets to be on a mission to be a capable team player, and was a fairly competent leader during a Danger Room session, but usually his immaturity gets in the way. Also note that Bobby is an Omega level mutant in the comics, but can't stay focused enough to achieve his full potential.
- Character Development: Starts off as nothing more than an extra face. By Season 4, he's officially taken over Evan's role in the series, getting to hang out with the main X-Men.
- Chick Magnet: He gets his own legion of island fangirls while on a vacation cruise, and enjoys showing off for them.
- Heterosexual Life-Partners: With Cannonball.
- The Hero: To the New Recruits anyway.
- An Ice Person: His codename is Iceman. What did you expect?
Code Name: Cannonball
Real Name: Samuel 'Sam' Guthrie
Voiced by Bill SwitzerThe tall, blond southern boy who joined at the same time as the other New Recruits. More well rounded and likable than Bobby in some respects, he's easily identifiable by being a head taller than most of the students, even some of the original cast.
- American Accents: A southern drawl, not really as strong as most versions though; tends to be Flanderized in fanfics.
- Barrier Warrior: Doesn't ever use his power to fight, he's more of an evacuation type person. In the final fight, all he does is fly Rogue to Apocalypse's strong hold.
- Flight: His power allows him to fly like a rocket, however unlike most people, he can't stop or float, meaning his only way to land is to crash.
- Heterosexual Life-Partners: With Bobby.
- Hoist by His Own Petard: Could have beat Logan in a race, but got cocky and decided to use his powers. Lost horribly because of this.
- Geek: Word of God bios for the New Recruits refer to him as such.
- Gentle Giant: The tallest of the New Recruits, but easily the nicest.
- The Klutz: He certainly crashes a lot.
- The Lancer / The Big Guy: To the New Recruits anyway.
- Ship Tease: Has a bit with Amara.
Code Name: Jubilee
Real Name: Jubilation Lee
Voiced by Chiara Zanni
"I'm totally chafed. Class dismissed. I'm outta here!"Usually seen with Bobby, Sam, and Jamie, Jubilee is the second most seen female mamber of the New Recruits during Season 2. She's Put on a Bus despite proving to be rather popular amongst some of the fans when the executives decided there were too many characters. She has the ability to shoot firework-like 'plasmoids' either in the shape of actual fireworks or beams. Easily identifiable by her yellow jacket.
- Brilliant, but Lazy: Her Word of God official bio describes her as this, not really shown however.
- Embarrassing First Name: Jubilation, never referred to as such in the show though.
- Lethal Harmless Powers: She fires explosive plasmoids! Regularly seen firing them at friends/other students.
- One of the Boys: Only seen hanging out with girls in two appearances; in every other scene, she's always with Bobby (and to lesser extent Sam and Jamie), either for his crazy adventures, or for the Ship Tease.
- Platonic Life-Partners: With Bobby, depending on who you ask.
- Put on a Bus: Alongside Wolfsbane she was written out at the beginning of season 3. Came back in the finale to help fight Apocalypse.
- Ship Tease: With Bobby, who she's usually paired up with in fanfics.
- Shout-Out: Constantly wears a yellow jacket when out of uniform. Season 2 ends with her clothes damaged enough to turn her normal jeans into shorts, making her look exactly how she did in the comics, only with longer hair.
- Tomboy: How some fanfics about her are usually written.
Code Name: Magma
Real Name: Amara Juliana Olivia Aquilla
Voiced by Alexandra CarterThe only one to get a focal episode (two actually) but also the most powerful. Magma, as her name suggests, can generate heat and fire, along with to some extent control lava. A princess in her home country, Amara is one of the more girly members of the group, not to mention a little of a Shrinking Violet at first.
- A Day in the Limelight: Ends up getting two focal episodes, "Walk On the Wild Side" and "Cruise Control".
- Defrosting Ice Queen: Similar to the one below, Amara was apparently going to be one of these, assumed to have mostly happened off screen.
- Everything's Better with Princesses: Not really mentioned or touched upon, but official bios confirm she's still a princess.
- Race Lift: She's actually from Brazil in both show and comics, but her comic appearance had her as a blue-eyed Caucasian Brazilian. In the show she is an Afro-Brazilian.
- Further complicated by the facts that, first, owing to its history, Brazil has a wide genetic pool, meaning that she could be justifiably darker than Storm or the above-mentioned Caucasian blond. Second, in the comics, she's from a lost Roman colony off South America called Nova Roma; this becomes less ridiculously implausible when you realise that Selene was behind its creation.
- Romantic Two-Girl Friendship: With Tabitha.
- Ship Tease: With Sam, explaining why they're paired up so frequently in fanfics.
- Shrinking Violet: A minor example.
- Sugar-and-Ice Personality: As with the above trope, a minor example.
- Tomboy and Girly Girl: Girly Girl to Tabitha's/Jubilee's Tomboy.
Code Name: Wolfsbane
Real Name: Rahne Sinclair
Voiced by Chantal StrandA Scottish mutant who can turn into a wolf or half-wolf whenever she wants. She spent most of her appearances in the background or as a wolf, but did speak in an episode or two. Like Jubilee, she was written out of the series, despite being popular, though her lack of importance to the plot is a noted factor.
- Fanservice: Got a swimsuit scene in the episode 'Retreat', not only the first to do so but also the only New Recruit girl to wear a two piece.
- Girlish Pigtails
- Our Werewolves Are Different: She's a mutant human girl who can turn into either a full wolf or half wolf/human hybrid, her clothes slowly disappear while transforming (they are likely made of unstable molecules, this being a Marvel Universe after all), only to reform while transforming.
- Not Completely Useless: Most of the time her power to turn into a dog seemed almost completely useless, until the kids needed her to sniff out Beast after he'd been kidnapped by some Big-Foot hunters.
- Put on a Bus: Until she was called in to help in the finale.
- Scotireland: Downplayed. She has a very mild to non-existent accent that almost sounds like the voice of a fairy.
- Ship Tease: She played around with Sam and helped Jamie with his homework which may explain her ships with them, but the most popular Rahne-related ships are with Roberto, based on the episode Retreat (being the only episode in which both of them actually speak in full sentences).
- The Voiceless: As said before, got two speaking roles; in one of them all she does is laugh a little, usually she's just in the background or in her wolf form.
Code Name: Sunspot
Real Name: Roberto da Costa
Voiced by Michael ColemanA rich Brazilian boy with the power to absorb solar energy to gain super human capabilities, such as strength, speed, agility, and, in the first season two episode, fly. He does very little for the show but still retains a small but dedicated fanbase.
- Flying Brick: Only seen flying once, but his powers make him one.
- The Power of the Sun: His power comes from sunlight.
- Ship Tease: With Rahne in the episode Retreat, Namely the scene in which they're both wearing Swimsuits and staring romantically at each other.
- Small Name, Big Ego: He's noted to be a little arrogant regarding his powers and abilities.
- Super Strength: Sunspot has the ability to absorb solar energy and convert it for use as physical strength.
- The Voiceless: Speaks in one episode only.
Code Name: Berzerker
Real Name: Ray Crisp
Voiced by Tony SampsonA Morlock in the comics, Ray is arguably one of the more popular characters in the series who got considerably more development here than his comic self.
- Aborted Arc: Was originally going to have a rivalry with Sunspot, but it was dropped after one episode.
- Ascended Extra: Appears once in the comics as an Axe-Crazy Morlock, here appears in a good number of B-Plots, usually as Bobby's second Male Best friend an speaks in almost every appearance.
- Berserk Button: Apparently hitting him in the face with a ball when using your powers in a non-powered game of volleyball is a sure fire way to set him off.
- Berserker Rage: His codename is Berzerker, after all.
- Big Brother Mentor: To the other New Recruits being the oldest among them.
- Jerk with a Heart of Gold: Word of God claims this as the reason they created him, they wanted a New Recruit who has a "bad boy" vibe, someone who acts tough but is really nice. In the show however he's almost always expressing the heart part.
- Multicolored Hair: He has blond hair with a spiked, orange fringe, possibly a dye job.
- Only Sane Man: Surprisingly, he comes off as one of the most mature of the New Mutants. Yes, he has a temper but that doesn't distract that he’s the least seen when the other members are doing their normal shenanigans
- Psycho Electro: Not as powerful or as psychotic as some, but does have serious anger issues which were addressed at times and did hold his own against Storm (who at the time had been upgraded by Apocalypse).
Code Name: Multiple
Real Name: James 'Jamie' Madrox
Voiced by David Kaye (not the one who voices Professor X)
"Awww I never get to go."The youngest of the ensemble, Jamie is like the little brother none of them wanted. His power is to duplicate himself, his clothes, and any object he's holding but only when hit with external kinetic energy (such as being hit/knocked over), which causes him to get in the way due to his clumsiness.
- Age Lift: He was Scott's age in the comics, while he's the youngest member of the New Mutants in the show.
- Annoying Younger Sibling: Not by blood, but still basically the same deal.
- Bratty Half-Pint: A rare, non-Scrappy case!
- Cheerful Child: Hence why he's not Multiple Man like the comics.
- In-Name-Only: Aside from retaining his real name and powers, he has nothing in common with his comic book counterpart.
- Precocious Crush: Hinted to have a bit of one on Kitty.
- Self-Duplication: Possesses the power to not only create clones of himself, but also of any objects that he might have knocked over.
- The Team Wannabe: He keeps begging and pleading to be let in on the antics the other kids get themselves into, it usually never works. Which is actually a good thing.
- Vague Age: While Word of God says they had no idea how old most of the characters were, Jamie's exact age in particular is uncertain, but they suggested he was around 12, which seems to fit.
Code Name: Spyke
Real Name: Evan Daniels
Voiced by Neil Denis
"Come on, Rogue, get with the program. Shake that thing!"A mutant from New York City and also Storm's nephew. He has the ability to project bone-like spikes from his skin. Spyke is stubborn and lacks respect for authority. This often puts him in conflict with the other X-Men. When his powers can't be controlled he leaves the X-Men, and joins the Morlocks, becoming their champion.
- Anti-Hero: Part of Evan's character development. At the start of the series he's a Classical Anti Hero; he's the least serious-minded of the cast, regularly skipping out on meetings and acting hot headed. After his secondary mutation, and seeing the living condition of the Morlocks, Spyke grows into a Pragmatic Hero, taking to vigilantism to protect mutants who are being bullied and attacked by humans, but his heart remains in the right place.
- The Big Guy: He's the most reckless and prone to violence on the X-Men team.
- Canon Foreigner: Evan doesn't exist in the regular Marvel universe, and due to the circumstances of his origin, won't ever (in the regular Marvel Universe, Storm's an only child).
- Commuting on a Bus: Part of the main cast for the first two and a half seasons. He leaves the X-Men during the third season to join the Morlocks. He is all but forgotten about till he reappears in a season four episode.
- Dark-Skinned Blond: It's a nod to his relationship with Storm (his aunt) who also has light-colored hair and is a mutant like him, while his parents possess the usual-colored dark hair of their ethnic group and are not mutants.
- Demoted to Extra: A major character in seasons one and two; in season three, he up and joins the Morlocks. Gets an episode here or there, but he's mostly gone. This wasn't necessarily a bad thing, because he was Rescued from the Scrappy Heap when he returned.
- Good Is Not Nice: In Season 4.
- Healing Factor: It’s how he can remove the bones from his body without bleeding to death or injuring himself.
- Hot-Blooded: It makes the future evolution of his powers quite fitting.
- Incendiary Exponent: Flaming spikes after "Uprising".
- Just Like Robin Hood: After joining the Morlocks. Though he never actually steals, he partakes in Street Justice to protect mutants.
- Power Incontinence: He initially had some difficulties with his powers going off without him wanting them to (accidentally taking out a light by stretching on waking up, for example). In fact, this is how Storm noticed he was a mutant: his powers subtly kicked off when he fell over in a game of basketball. Then, in season 3, it got worse. So much worse.
- The Rival: To Quicksilver in their introductory episode.
- Skeletons in the Coat Closet: An involuntary version of the trope "Uprising".
- Spear Counterpart: To the comics' Marrow, powerset-wise (and him joining the Morlocks later also reflects this, since Marrow was a Morlock to begin with). The show's producers stated that, at the time, they didn't know about Marrow, hence why Spyke's so similar to her.
- Spike Shooter: His usual use of his powers is shooting out projectiles.
- Taking the Bullet: In "Uprising", he takes an energy blast from a laser gun that was intended for Leech.
- Token Minority: He's the only black member of the team (or at least the students) in the first season.
- Took a Level in Badass: After joining the Morlocks.
- Too Qualified to Apply: In one episode, he enters a skateboarding contest and performs well, but is pressured by the other contestants into forfeiting because of his mutant genes. Spyke insists his mutation doesn't affect his ability to skateboard, but leaves the contest anyway, feeling that when the judges find out he's a mutant, he's not going to stand a chance of winning anyway.
- Totally Radical: If the hair and skateboard weren't enough of a clue.
- Troubled, but Cute: He's a scruffy athletic teen rebel with a penchant for trouble. And even after his secondary mutation, is still not exactly ugly.
- Well-Intentioned Extremist: In "Uprising", he goes to great lengths to defend mutants from mutant-hating bigots.
- Age Lift: With the exception of Tabitha, and possibly Pietro & Wanda, most of the characters were already adults when we first see them in the comics. Here, only Magneto and Mystique are adults.
- Delinquent: The Brotherhood boys. They skip school, get into fights with the X-Men, and commit petty crimes such as vandalism and theft.
- Enemy Mine: They've worked with the X-Men on several occasions, usually out of necessity.
- Kick the Son of a Bitch: In "No Good Deed", they threaten Edward Kelly into leaving them out of his anti-mutant crusade. Considering that the man's a bigot who mistreats (and encourages mistreatment of) his own students who happen to be mutants, and also brought it upon himself with his anti-mutant speeches, it's hard to feel sorry for him.
- Lighter and Softer: The Brotherhood are portrayed as trouble making teenagers instead of terrorists as in the comics and other versions.
Code Name: Avalanche
Real Name: Lance Alvers
Voiced by Christopher Grey
"You're making it yours, Kitty. Once you own it, nothing can own you."A mutant with the ability to manipulate the earth by generating seismic waves from his body. Avalanche came from the same town as Shadowcat, but had a very different upbringing. He grew up as a streetwise orphan who seemed angry at the world. Confused and alienated, he was a perfect target for Mystique and the Brotherhood. Lance was one of the most complex characters. He started off as a punk, before becoming more of a troubled youth, and then ultimately showing responsibility and maturity. His romantic interest in Kitty Pryde and their relationship played a major role in his attempts to change. It even leads him to attempt a major Heel–Face Turn by joining the X-Men. As the oldest Brotherhood member, Lance is often the defacto leader and feels responsible for the others.
- '80s Hair: Has a mullet hairstyle that goes with his grungy, rebellious loner image.
- Adaptational Nice Guy: He went from a unsympathetic Psycho for Hire or Punch-Clock Villain in the comics to an angry, yet notably sympathetic character in the show.
- Adaptation Name Change: In the comics, his real name was Dominikos Ioannis Petrakis. It was changed to a more Americanized name, Lance Alvers.
- Arch-Enemy: Cyclops.
- Berserk Button: Since Season Two on, for your own good don't hurt or threaten Kitty.
- Big, Thin, Short Trio: The "Thin" to Blob's "Big" and Toad's "Short".
- Characterization Marches On: In his first episode, he's destroying his school without remorse, as well as trying to manipulate Kitty's feelings and eventually trying to kill her and her parents. In following episodes, his powers generate an Oh, Crap! response to being love-struck with Kitty for the second season to then not even bothering any more either way to the third. In the fourth he becomes a Jerk with a Heart of Gold and is shown to be the most powerful member of the Brotherhood, possibly even more so than the other villains not over 50.
- Composite Character: Lance has nothing in common with the comic book Avalanche outside of the codename, team affiliation and powers. He is more an expy of the X-Men character Julio Esteban Richter aka Rictor, in his looks, personality, and the way he channels his seismic powers. In the first season he had more in common with his comic self, but not by much.
- Dating Catwoman: He dates Shadowcat during the second season. The Brotherhood tease him for this.
- Dishing Out Dirt: His mutant power allows him to generate seismic waves, creating earthquakes.
- Evil Counterpart / Foil: To Cyclops - both are a Big Brother Mentor and usually the most responsible member of their team, both are orphans, and both tend to take the initiative. The differences end there though as while Scott is calm and collected, Lance is impatient and impulsive, and Scott has turned his own misfortunes in life towards more productive endeavours as opposed to Lance's self-destructive behaviour. Small wonder they're each other's Arch-Enemy.
- Four-Man Band: Only Sane Man
- Heel–Face Turn: Attempted one and almost succeeded, but settled in as a Wild Card.
- Hot-Blooded: Lance gets very annoyed easily, as he’s often irrational and driven by his temper.
- In-Name-Only: Due to being an expy of an X-Men character named Julio Esteban Richter aka Rictor, Lance has nothing in common with the Avalanche of the comics outside of his codename, powers and team affiliation.
- Jerk with a Heart of Gold: Starts out as a Jerk Ass in the first season, before becoming a Jerk with a Heart of Gold at the start of the fourth season.
- Leit Motif: Summoning it is his main power. The earthquakes are just a Required Secondary Power.
- Love Redeems: Somewhat. He definitely tries to change for Kitty, but can go only so far, and decides to not stay in the New Mutants group after his disastrous and brief stint there. His heroic acts in No Good Deed had nothing to do with Kitty, which showed he had it in him all along. He also showed up with the rest of the Brotherhood in Ascension part 2 to help the X-Men fight Apocalypse after first refusing. He immediately goes to save Kitty, which can be either seen as their romance being reignited or a simple Pet the Dog moment from him.
- Pretty Boy: He's re-designed as a Troubled, but Cute Jerk with a Heart of Gold bad boy with the looks of Judd Nelson from The Breakfast Club.
- Race Lift: The comics' Avalanche was Greek. Presumably he was made American to ease him fitting into the setting (although the does have the darker features such as olive skin tone, dark hair and eyes).
- Steven Ulysses Perhero: If you switch his first and last names you get pretty close to his codename.
- Tall, Dark, Handsome AND Snarky.: He's one of the taller characters on the show, has dark hair and features, and he definitely has some snark.
- Troubled, but Cute: Bad boy, check. Rebel attitude, check. Antisocial behavior, check. Difficult home life, check. Fingerless gloves, check. Heart of gold, check.
- Unskilled, but Strong: Has the potential to be the most destructive recurring mutant in the series short of a Big Bad like Magneto or Apocalypse (and even then, it's close) and for the most part is, but he lacks the control and the patience to make him a real powerhouse.
Code Name: Quicksilver
Real Name: Pietro Maximoff
Voiced by Richard Ian Cox
"Look, when you live as fast as I do, there ain't enough things to occupy my time. I gotta entertain myself."A mutant that can move at the speed of sound. Pietro is arrogant, deceptive and his loyalty is always in question. He would betray the Brotherhood and his sister Wanda at the command of his father Magneto, yet showed no compassion at his father's disappearance at the hands of Apocalypse. Pietro has a stormy relationship with his twin sister, although their relationship, as well the one with his Brotherhood teammates, improve during season four.
- Adaptational Villainy: Comic book Pietro, while arrogant, was in the end an Anti-Villain who worked for Magneto only because he felt like he owed him, and eventually pulled a Heel–Face Turn, becoming an Avenger. By contrast, this incarnation of him almost lacks any redeeming qualities, and might actually be one of the least sympathetic members of the Brotherhood.
- Arch-Enemy: In his introductory episode with Spyke, which sets him up as The Rival. This doesn't show up in many later episodes though, mostly because Spyke joins the Morlocks.
- Beneath the Mask: Pietro seems to be hiding a heck of a lot under his usual cockiness.
- Big Brother Instinct: Does genuinely have one towards Wanda, when she isn't trying to murder him. This is best demonstrated in the final episode when he saves Wanda from being killed by Magneto.
- The Casanova: Or at least, the potential to become one. The episode with the dance has Boom-Boom implying that the members of the Brotherhood (besides Lance) don't want to go because they can't get dates. Blob and Toad go with Boom-Boom. Pietro shows up with four random girls.
- Chick Magnet: He showed up to the school dance with four girls on his arms. And he still manages to land himself dates even after he's outed as a mutant.
- Chronic Backstabbing Disorder: He supposedly works with the Brotherhood, but often goes behind their back at Magneto's request. His lack of loyalty aggravates Lance, to say the least.
- Disappeared Dad: His dad came back, and that's where all the trouble for Pietro started.
- Everything's Better with Spinning: Quicksilver can create whirlwinds by running around his enemies at top speed.
- Four-Man Band: The Smart Guy
- Fragile Speedster: He may be able to break the sound barrier and deliver punches at the speed of light, but if Pietro gets hit once by any attack (regardless of its strength) it usually sends him down for the count.
- Mystical White Hair: Subverted. Although he is superpowered, his white hair is simply inherited from his father Magneto.
- Not Quite Dead: During the finale of the first season, when the asteriod blew up, many fans speculated that Pietro had been killed because he was not shown with the rest of the Brotherhood. Actually, in a blink-and-you'll-miss-it scene, the unconscious Pietro was carried to safety by Spyke.
- The Smart Guy: Of the Brotherhood, at least, which might not really say that much.
- Smug Snake: Pietro acts arrogant and smug when in control of a situation or fight but as soon as the tables are turned, he becomes a Dirty Coward who runs away.
- Smug Super: He can move too fast to be seen, calling everyone slowpokes and he doesn't hesitate to rub it in peoples' faces.
- Strong Family Resemblance: Looks almost exactly like his father, down to the white hair.
- Super Speed: His mutant ability.
- Thicker Than Water: Willing to betray his entire team, including his sister, in order to help Magneto during the Sentinel. Doesn't seem to fully recover from this until Season 4.
- Weak, but Skilled: Pietro is a full-blown Fragile Speedster and in most direct confrontations he goes down in one hit. However, Pietro is the first member of the brotherhood seen with considerable control of his power and the other aspects his power might give him, no doubt having trained in its uses alongside his father. It’s to be noted that Pietro is often the Brotherhood member who wins the most battles (or at least before the inclusion of his sister on the team), combined with Motor Mouth Casual Danger Dialogue.
- "Well Done, Son!" Guy: Pietro constantly looks for approval from his father. It explains (but does not justify) a LOT.
- White Hair, Black Heart: Well, more Jerkass than evil, though.
Code Name: Toad
Real Name: Todd Tolansky
Voiced by Noel Fisher
"Hey, if you can't be cool, be feared. My momma always told me that."A repugnant mutant who physically resembles a humanoid toad. Like a toad, he can leap great distances, and possesses an extremely long and agile tongue. A social outcast, he has found some acceptance with the Brotherhood, where his talents for thievery and petty crime can be put to good use. Toad is often portrayed as the whipping boy of the Brotherhood, but he also is treated like a little brother, and is even protected by Blob. Toad is known for his extremely poor hygiene which doesn't help him in his attempts to get Wanda Maximoff to like him.
- Adaptational Name Change: His name is Mortimer Toynbee in the comics.
- Adaptational Nationality: Toad is British in the comics. In this show, he's an American.
- Adorkable: In his better days.
- Alliterative Name: Todd Tolansky.
- American Accents: Noo Yawk, yo.
- Arch-Enemy: Nightcrawler.
- Big, Thin, Short Trio: The "Short" to Avalanche's "Thin" and Blob's "Big".
- Butt-Monkey: Pretty much defines him.[After crashing a jet into a possessed Magneto] Did we win? [metal starts flying around] Oh yeah... we never win.
- Four-Man Band: The Pervert- even though he isn't really a pervert. He often alternates between being the Butt-Monkey with Fred.
- Fun Personified: Toad is this for The Brotherhood. It's to the point that a large majority of the show's comedy is derived solely from him.
- Good Eyes, Evil Eyes: Has very pale yellow eyes when in civilian mode and red eyes when in villain mode. Either he wears yellow contacts as a disguise that looks as unnatural as his real colour, or wears red contacts to look even weirder, or has the pointless and un-toadlike ability to change his eye colour.
- Hopeless Suitor: Even though he has zero chance, he still pursues Wanda,
- Continuity Nod: The original Toad was this to the original Scarlet Witch too
- Leitmotif: Sing it with me...T-O-A-D, T-O-A-D! Iss'sall good, yo! See I know, some things ya gotta undastand about Toad.
- The Pig Pen: Probably some of his oft-commented upon body odour is due to his mutation, but the fact he showers on a monthly basis ain't helping.
- Plucky Comic Relief: One of the funniest characters in the series.
- Puppy-Dog Eyes: He has a habit of making these.
- Race Lift: Same deal as Avalanche, except Toad was British in the comics.
- Screams Like a Little Girl: He has a very, high-pitched girly scream as shown whenever somebody or something scary is out for his blood.
Code Name: Blob
Real Name: Fred Dukes
Voiced by Michael Dobson
"Unstoppable? Meet the unmovable!"A humongous boy from Texas, Fred Dukes is among the strongest mutants in the world. Blob is the least intelligent of the Brotherhood, but his brawn helps counterbalance his lack of brains. His hefty build and less than charming personality often make him a target of public ridicule. The social isolation and bad temper made him a prime candidate for recruitment into the Brotherhood by Mystique. He was initially treated well by the X-Men until he attempted to kidnap Jean.
- Adaptational Dye Job: He has blond hair here instead of the red/brown hair that his comic book counterpart has.
- Adaptational Nice Guy: Blob was close, though his friendship with Toad made him slightly more morally light than his comic self.
- Berserk Button: DO NOT LAUGH AT THE BLOB!
- Big, Thin, Short Trio: The "Big" to Avalanche's "Thin" and Toad's "Short".
- Dumb Muscle: Definitely not the brightest, but he's strong enough to serve as The Brute for the Brotherhood.
- Gravity Master: Can alter his own personal gravitational field to root himself to a spot and become immovable while taking advantage of his incredible durability and resistance to harm.
- Pet the Dog: He treats Toad like a little brother and is more of a Gentle Giant when Mystique isn't around.
- Stalker with a Crush: He took Jean being nice to him to mean she liked him. Unreasonable expectations indeed.
- Villainous Glutton: In the comics, his bulk is due to his mutation, but in the show, he is already very fat before he developed his powers. So it is possibly a combination of the two.
The Scarlet Witch
Code Name: Scarlet Witch
Real Name: Wanda Maximoff
Voiced by Kelly Sheridan
"You haven't seen me angry... until now!"Wanda was sent to an asylum by her father Magneto shortly after her mutant powers emerged. Magneto claimed it was necessary because he was unable to help control her dangerous powers, but Wanda always resented him for it. Mystique helped Wanda escape from the asylum in order to bolster the Brotherhood ranks. However, Wanda was more interested in revenge against her father than fighting for the Brotherhood. Wanda suffers from emotional damage from her years locked up in an asylum. But she appears to regain much of her sanity as the series progresses. Wanda has the ability to "hex" other mutants' powers to make them go haywire.
- Adaptation Dye-Job: Her natural hair color is brunette in the comics but here, she's raven-haired.
- Adaptational Modesty: She wears less revealing outfits than her comic counterpart.
- Adaptational Villainy: In the comics, She and Pietro both only became villains because Magneto saved their asses and they owed him; both of them eventually became aware of his true nature when they joined the Avengers. In the show, Wanda is a perpetually angry and dangerously unstable girl with sympathetic, but not heroic qualities.
- Antagonistic Offspring: An Eviler Than Thou variation. When Mystique breaks her out of the asylum, the Scarlet Witch spends the rest of the show trying to hunt down her father and exact her revenge upon him for institutionising her when she was child because she couldn't control her Reality Warper powers.
- Ax-Crazy: When it comes to Magneto and Quicksilver.
- Bare Your Midriff: She shows off her navel when wearing her civvies outfit (a red, brocade vest top).
- Berserk Button: Magneto abandoning her, period.
- Color Character: Red. In both her civvies and battle uniform, Wanda wears red and black clothing and the bottom layer of her hair is red. She wears dark-red eyeshadow makeup, lipstick, and nail-polish, and her codename is Scarlet Witch.
- Curb-Stomp Battle: In her first appearance, she absolutely devastated the X-Men.
- Cute and Psycho: Voracious, hair-trigger temper? Check. Adorable? Also check.
- Cute Witch: Her mutant powers? Hex powers or magic? Or mutant powers that let her tap into magic? Also she's a pretty raven-haired girl. No matter which, she qualifies.
- Fake Memories: Had these implanted by Mastermind - he basically replaced every bad memory she had of Magneto with good ones.
- Goth: Her fashion style, even moreso than Rogue.
- Goth Girls Know Magic: She's the most gothy girl in the cast, and her hex bolts are highly reminiscent of magic.
- Hair-Trigger Temper: Wanda’s temper has caused almost every character she’s confronted to fear her.
- Important Haircut: After her training with Agatha Harkness, Wanda cuts her wild, unkempt shoulder-length hair to a closely cropped hairstyle. The haircut seems to symbolize as her being more focused and determined to start her revenge against her father.
- Magical Gesture: Wanda must have free usage of her hands in order to use her probability-altering powers, as she uses a lot of hand gestures and finger motions to channel them.
- Mind Rape: Magneto has Mastermind do this to her, replacing her bad memories with good ones so she believes Magneto was a loving father.
- Parental Abandonment: The source of her issues.
- Perpetual Frowner: Her default facial expression is either an angry scowl or bitter indifference. She has only ever smiled twice and both times were after Mastermind had fiddled with her head.
- Roaring Rampage of Revenge: Wanda spent much of her introductory series searching for her father with her initial mission to kill him for wronging her. She does eventually find and attempt to kill him twice.
- Sanity Strengthening: Ironically, she became less psycho and more kind and helpful towards others after Mastermind messed with her head.
- The Unfavorite: Magneto always chooses Quicksilver over her. Now you know why she hates her brother.
- Winds of Destiny, Change: Her mutant ability to harness and manipulate the force of probability.
Code Name: Magneto
Real Name: Erik Magnus Lehnsherr
Voiced by Christopher Judge
"And now the whole world will know of us."The mysterious Magneto is one of the most powerful mutants alive. He has a long history with Charles Xavier, both as a friend and an enemy. Magneto has given up on the idea of peaceful co-existence between mutants and humans. His philosophy is in direct opposite to that of Xavier, who still believes mutants and humans can live together in relative peace. Magneto envisions himself and other mutants dominating over humanity as the only way to prevent bloodshed between the two groups. However, Magneto's dream is threatened by Apocalypse who has his own plans for world domination.
- Affably Evil: You can't ignore the fact that, as always, there is a certain charm to Magneto. And he tends to be quite friendly. Until you say no.
- Ambiguously Jewish: In the episode Operation: Rebirth, Wolverine rescues a young Erik from a WWII German controlled camp. Although it was not named in the episode, it was clearly a Nazi concentration camp.
- Arch-Enemy: How Magneto sees Professor Xavier.
- Badass Cape: The Master of Magnetism rocks an imposing purple/red cape in this incarnation.
- Big Bad: In the first two seasons.
- Brainwashed and Crazy: Is defeated by Apocalypse and turned into one of his Horsemen.
- The Chessmaster: He orchestrated the unveiling of mutants to the entire world by using the X-Men and Bolivar Trask's Sentinel Project.
- Evil Sounds Deep: Courtesy of his VA.
- The Faceless: His face always appears shadowed by his helmet in Season 1, until the double-episode season finale.
- Heel–Face Turn: Both just after being saved from Apocalypse, and in the future Xavier saw.
- It's All About Me: His motivation to bring down Apocalypse is fueled by his desire to be the only one to lead the mutants to a better world and no one else is going to rule the world with him around.
- Knight of Cerebus: Brought upon the first of many dark arcs in this series, and managed to also cause a dark shift in the overall plot at the end of the second season.
- Leitmotif: An quiet, ominous theme with a piano which crescendoes in and out.
- Noble Demon: He has moral lines he won't cross.
- Older Than They Look: Statements about his age would put him at least in his 60s or 70s, but he appears much younger than that.
- Parental Neglect/Abusive Dad/Parents as People: He zigzags between these three tropes in his relationship with his children, Pietro and Wanda.
Code Name: Mystique
Real Name: Raven Darkholme
Voiced by Colleen Wheeler
"Come on boys, let's get out of here before you're invited to a slumber party."Mystique is the leader of the Brotherhood, but took orders from Magneto, until leaving him after she felt he questioned her loyalty and talent. She is intelligent, cunning, deceptive and very dangerous due to her shapeshifting abilities.
She changed into human form and used the name Raven Darkholme to became the Bayville High school principal, giving her the opportunity to monitor Xavier's students as well as her Brotherhood members. Later, she fought Storm, but was easily punched out. Afterwards, she helped the X-Men fight Magneto, but was knocked into his enhancement machine, and was presumed dead by the X-Men following Asteroid M's destruction.
But she returned later, with a permanent Race Lift applied to her by Storm's aforementioned punch. She infiltrated and destroyed Xavier's school by disguising herself as Professor X. Several students barely escaped with their lives.
She raised Rogue and is Nightcrawler's mother, although neither knew her true identity growing up.
- Accent Relapse: Speaks with a Canadian accent, but would sometimes slip into a German/Austrian accent when stressed or angry, hinting at her nationality from the comics and her relation to Nightcrawler. This was dropped after season one.
- Adaptational Wimp: Played with... this show's incarnation of Mystique is much less capable in a fight than any other incarnations, but she does have powers that her 616 and film counterparts lack (like the ability to turn into animals). She gets a power boost in the first season finale that renders her more bestial-looking but stronger, and while that boost eventually goes away she does retain her more varied shapeshifting abilities and a bit of the strength as well.
- Alleged Lookalikes / Unusually Uninteresting Sight: Almost nobody (except for maybe Avalanche and Toad) in the entire series seems to notice or comment on the fact that Mystique has a radically different appearance after the events of season 1.
- Arch-Enemy: Was this to Storm during the first season.
- Big Bad: In a Five-Bad Band sense. She acts as the leader of the Brotherhood while looking to break out from under Magneto. This arguably makes her Co-Dragons to Magneto alongside Sabretooth.
- Big Bad Wannabe: This trope hits Mystique very hard during the first season. She appears to be the leader of the Brotherhood, but is actually subordinate to Magneto, who is implied to abuse and torment her whenever she disobeys or angers him.
- Bi the Way: Steven E. Gordon stated that Mystique is in a lesbian relationship with Destiny, just like in the original comics. However, she also shows signs of being interested in men as well. See Foe Romance Subtext and Villainous Crush below.
- Brainwashed and Crazy: She is turned into one of Apocalypse's Horsemen.
- Canada, Eh?: In the first season, she speaks with a very robotic Canadian accent, which becomes a more convincing American in later seasons.
- Characterization Marches On: In season one, she was a Faux Action Girl that was chronically knocked out or incapacitated whenever she got into a real fight, and had to rely on either having other mutants fight for her or using her shapeshifting ability and trickery to manipulate others. Even then, she was more mischievous than dangerous, only being a legitimate threat on her own when she tried to kill Scott in "Turn of the Rogue". However, after her enhancements in the season one finale, she became much more lethal and threatening as a villain.
- Combat Sadomasochist: She actually enjoys being knocked unconscious by other women and becomes obsessed with the ones that do so. This has gone to the point where she has frequently allowed Rogue to touch her and drain her of her energy several times in the series, even until she fainted.
- Dark Action Girl: Holds her own in a fight against Cyclops.
- Deer in the Headlights: In "The Cauldron Part 1", Mystique looks on in complete horror as Storm comes running towards her out of the fog with a raised fist, and does nothing to stop her from knocking her out.
- Evil Plan: She pulls off a great one on the X-Men by impersonating the then-missing Professor X and getting Wolverine to go missing so he won't identify her. Only Scott's surprise arrival foiled this.
- Evil Redhead: In her natural form, she's a redhead.
- Evil Teacher: As Principal Darkholme in the first season.
- Failure Is the Only Option: In the first season, Mystique always lost any battle she had against Storm.
- Fanservice Pack: After the incident with Asteroid M, Mystique ended up changing from her comic outfit into a leather crop top, miniskirt, and matching high-heeled boots.
- Foe Romance Subtext: When Mystique is forced to work with the X-Men in "The Cauldron: Part 2", she exhibits signs of this with Wolverine. For a brief moment on the XM Velocity, she's seen curiously eying Wolverine, who she's sitting right next to, before turning her head away with an awkward expression on her face.
- Give Geeks a Chance: Implied in season 2, since she is frequently seen hanging around Arcade in "Fun & Games", and apparently falls in love with Forge towards the end of "Shadow Games". Both times, she's disguised as Risty Wilde.
- Gray Eyes: Has these in season 1, although they're more like Milky White Eyes that happen to have gray pupils.
- Hair Decorations: Wears a triangular yellow pendant on her forehead.
- Harmless Villain: Storm seems to view her as one in "The Cauldron, Part 1", treating her more like a nuisance than a real enemy when they fight each other.
- Heel–Face Door-Slam: Following the battle with Apocalypse, Mystique makes overtures of reconciliation with Kurt and Rogue. Though whether she meant it or not depends on the view of the individual, her children make it clear they've had enough of her Chronic Back Stabbing Disorder and want nothing to do with her.
- Hell-Bent for Leather: After the first season.
- Hime Cut: Has a variation of one in the first season.
- In the Hood: In "Shadowed Past".
- Ink-Suit Actor: As seen on the DVD special features cast interview, her first season appearance looks a lot like her voice actress with blue skin.
- Kurt, I Am Your Mother: Revealed quite early in Season 1. When Kurt finds out at first, he's less than pleased.
- Mommy Had A Good Reason For Abandoning You: Turns out she didn't intentionally abandon Kurt in this version. Turns out she'd accidentally dropped him into a river when he was a baby, when she found out he was alive she left him with the couple that found him, wanting to Give Him a Normal Life.
- Ms. Fanservice: Wears a leather outfit that shows more of her skin and midriff after the first season.
- Pet the Dog: Impersonates a police officer to keep the Bayville Sirens from getting arrested, seemingly just because she supported them sticking it to the guys.
- Power-Upgrading Deformation: The enhancements applied to her in "The Cauldron, Part 2" turn her into a significantly less attractive, muscular version of her movie incarnation's reptilian form (albeit clothed). Even after most of the enhancements wear off by season 2, her true form, while not necessarily hideous, becomes more feral in appearance, with yellow cat-like eyes, fangs, and a generally darker color scheme. A very clear contrast from the clean-cut, sophisticated appearance she had in the previous season.
- Raven Hair, Ivory Skin: When disguised as Principal Darkholme.
- Reformed, but Rejected: At least that's the impression she tried to give Kurt and Rogue by the end of the series.
- Salt and Pepper: She is the Salt to Storm's Pepper.
- The Starscream: She was always looking to break out from under Magneto.
- Statuesque Stunner: 5"10, to be precise.
- The Vamp: An embodiment of this trope, particularly during the first season.
- Villain Decay: In the later episodes of the show's third season, she loses all presence as a villain and becomes a pawn for Mesmero. In a couple episodes, she was only present just so that Rogue could absorb her powers.
- Villainous Crush: Implied to have one for Forge, as seen in "Shadow Dance".
Code Name: Boom-Boom
Real Name: Tabitha Smith
Voiced by Megan Leitch
"Yeah! Look out below. Boom Boom is bombin' in. Whoohooo!"Boom-Boom is a mutant with the ability to create explosive balls of energy. Her father took advantage of her mutant abilities to commit crimes when she was younger. She eventually found a home at the Institute, although her stay was short-lived. She found she fit in much better with the rebellious Brotherhood and liked having four boys she could manipulate and pull pranks on. She was kicked out of the Brotherhood when Mystique returned. She is later seem hanging out with the X-Men through her friendship with Magma, but never rejoins them and appears to live on her own. While not malicious, the lack of discipline and mischievousness made her a troublesome guest for anyone willing to take her in.
- Abusive Parents: Her dad is an ex-con who tries forcing Boom-Boom to help him with his robberies.
- Cool Big Sis: A bit of one towards Amara.
- Heel–Face Revolving Door: Though she only really joined the Brotherhood while Mystique was MIA and they were mostly just being harmless mild jerks, and when push comes to shove, she's always on the right side.
- Manic Pixie Dream Girl: She becomes this to the X-Men girls as she tries to get them to loosen up in what can only be described as an entire Big-Lipped Alligator Moment episode.
- Pet the Dog:
- When Blob and Toad complain about them not having dates for a party, she takes both of them as her dates.
- Also, her relationship with Amara.
- Pretty Freeloader: Her looks got her into the Brotherhood boarding house and kept her there no matter what stunt she pulled.
- Romantic Two-Girl Friendship: With a slight stretch, you could see this in her relationship with Amara (Magma). And 'lo, did the Yuri Fans squee at that.
- Sticky Fingers: She pretty much took anything she wanted. She liked Lance's Jeep so much she "borrowed" it when she wanted, even after she left the Brotherhood.
- Tomboy and Girly Girl: Tomboy to Magma's Girly Girl.
Code Name: Sabretooth
Real Name: Victor Creed
Voiced by Michael Donovan
"One shall fall by the other's hand. Our destiny we can't change it."A violent man who has a deep enmity against Logan. Little is revealed about Sabretooth's past except that he had some involvement with Wolverine and the Weapon X project (possibly being a test subject), and that he is one of Magneto's most loyal followers.
- Adaptational Nice Guy: While this Sabertooth is still his ever lovably psychotic, morally reprehensible self, he's fanatically loyal to Magneto for some strange reason as with most adaptations. In contrast, the comic Sabretooth would be unable to stand working with him for more than a few hours before stabbing him in the back.
- Arch-Enemy: To Wolverine.
- Ax-Crazy: Has a bloodlust that only mindless battle seems to satisfy. And unlike Wolverine, he fully embraces his feral instincts.
- Beast Man: He has a very hirsute physique with Barbarian Longhair, along with fangs and claws that don't seem to be retractable. He is also capable of lion-like roars and growls.
- Blood Knight: He really loves to fight.
- The Dragon: To Magneto in the first two seasons.
- Healing Factor: Less powerful than Wolverine's, but still more than sufficient.
- Lightning Bruiser: This is a big part of why he's so dangerous. He's massively strong, but he's also extremely quick and has superhumanly efficient joints and musculature that provides him with agility and grace that is far beyond what any normal human can pull off.
- Psycho for Hire: He was depicted as a loner in the first season, but from the first season's finale onward he is almost never seen without Magneto and he's shown to willingly perform tasks for him. Although once Magneto gets axed off by Apocalypse, Sabertooth vanishes without a trace. So it's more than likely he sees serving Magneto as a convenient way to further his own agenda.
Code Name: Gambit
Real Name: Remy LeBeau
Voiced by Alessandro Juliani
"It's the X-Men, and it looks like they want to play!"Trained as a thief, Gambit is a mercenary who will give his services to the highest bidder. He appears to have developed quite the soft spot for Rogue, especially during the season four episode, "Cajun Spice", in which he gives her his favourite card (the Queen of Hearts, his "lucky lady") at the end.
- Adaptational Villainy: Gambit was at least heroic Gentleman Thief in the comics (despite his start as an Unwitting Pawn for Mister Sinister), while here he's described as 'amoral' and only caring of personal gain but with a soft spot, turning him from an Anti-Hero into an Anti-Villain.
- Art Evolution: Gambit appeared with normal eyes (brown iris and white sclera), which were later modified into how they look in the comics (red iris and black sclera).
- Badass Beard: Nice goatee, man.
- Badass Longcoat: Part of his wardrobe along with Fingerless Gloves.
- Heel–Face Turn: Shown post-series to where he eventually joins the X-Men.
- Improbable Weapon User: The exploding playing cards, not the bo staff.
- Only Sane Man: During the search for Apocalypse, he gets between Magneto and Colossus during their fight and reminds them that they have bigger concerns at the moment.
Code Name: Colossus
Real Name: Piotr Rasputin
Voiced by Michael Adamthwaite
"I am not a lackey! I... I have no choice."Piotr is pressured into serving Magneto, who had abducted his family. Though after Magneto was captured by Apocalypse, it was suggested that he freed them and escaped with them to Russia.
- Adaptational Villainy: In the comics, he's a member of the X-Men. Here, he works for Magneto, albeit involuntarily. However, Xavier's vision of the future X-Men lineup includes him as well, making this a subversion.
- Anti-Villain: A type-4. The only reason he even works for Magneto is to protect his family.
- Apologetic Attacker: When Wolverine asks him why he fights for Magneto, he becomes melancholy and quietly says that it wasn't his choice.
- The Brute: Co-Brute with Pyro.
- Chrome Champion: He can transform at will from a normal (though fairly large and muscular) flesh-and-blood human to what the comics refer to as "organic" osmium steel.
- The Dog Bites Back: He finally has enough of Magneto's abuse during the search for Apocalypse and reverts to his non-metal form, effectively neutralizing Magneto's greatest advantage over him and easily manhandling him until Gambit reminds them that Apocalypse is the higher priority.
- Heel–Face Turn: Post-series. He's shown in Xavier's vision of the future line-up of the X-Men.
- Husky Russkie: He's Russian, and very big and muscular even when he's not transformed.
- Russian Guy Suffers Most: The details aren't explicit, but Magneto keeps his loyalty by threatening his family.
Code Name: Pyro
Real Name: John Allerdyce
Voiced by Trevor Devall
"Awful bold of you coming here, girl! Or are you just stupid?"Pyro is a crazy pyromaniac with a cackling laugh and a broken Australian accent. He has an affinity for destruction and complete ignorance of consequence border on outright insanity. In one notable scene he is watching footage of Magneto's supposed demise at the hands of Apocalypse, rewinding, playing back, and laughing several times. He differs from his comic book counterpart in that he needs a constant stream of flame to sustain his power.
- Adaptational Jerkass: In the comics, while Pyro was a somewhat unstable and violence prone Large Ham, he had an undying loyalty to his friends and eventually died a hero. Here, he is as much of a sociopath as Pietro.
- The Brute: Co-Brute with Colossus.
- Evil Laugh: He practically laughs more than he talks.
- Jesus Taboo: His first name in the comics is St. John. The "Saint" gets dropped for the adaptation.
- Laughably Evil: He seems to communicate exclusively through a combination of maniacal laughter and lame puns.
- Playing with Fire: Pryo can control fire, but he can't create it himself. He often carries around his own portable flamethrowers to do the job for him.
- Psycho for Hire: He's an eccentric and crazed thug, who willingly perform tasks for Magneto, though he clearly does it for the thrill more than any actual payment or respect for his boss. But that doesn't stop him from having a good laugh at the prospect of barbecuing his victims.
- Pyro Maniac: A more subdued version, but there were times when he showed just how much he relished setting things aflame.
- Sixth Ranger: Joins the Brotherhood in the future.
Code Name: Mastermind
Real Name: Jason Wyngarde
Voiced by Campbell LaneHe's the gang's telepath. While his comic book counterpart could only cast illusions, this version of Mastermind uses telepathy, as well as reading and even rewriting memories of other people like what he did to Wanda.
- Adaptational Nice Guy: Subverted. Mastermind is mostly the same as in the comics (which is a rare example in this series), but with his spine removed so he's unquestionably obedient to Magneto and mostly uses his powers to avoid being throttled, while his comic self would gladly go after the X-Men on his own, with or without Magneto.
Code Name: Apocalypse
Real Name: En Sabah Nur
Voiced by David Kaye
"The future came to me in that craft — I have embraced it and merged with its power so that I may lead the evolution of the human race."Apocalypse is an ancient Egyptian mutant; he's the oldest character on the show, and also the most powerful. Millennia ago, he conquered Egypt and planned to use advanced technology (stolen from the previous Pharaoh, who had "descended from the sky") to reshape the world in his own image- turning many humans into mutants, and killing the rest. His court balked at the idea and used his own technology to imprison him; however, Apocalypse was still able to reach out telepathically and manipulate his release. Steals the spotlight from Magneto as premier villain in the later part of the series.
- Adaptational Badass: This version of the character may be the strongest, and he's slightly less evil.
- Adaptational Nice Guy: Downplayed, but regular Apocalypse is an utter monster. This version's a Well-Intentioned Extremist.
- Bald of Evil: He's big, blue, bad and totally bald.
- Big Bad: Season 3 and especially in Season 4.
- Continuity Nod: Beast mentions that Apocalypse stole his tech from Pharaoh Rama-Tut. This is true in the comics as well, where Rama-Tut was an alias of Kang the Conqueror.
- Curb-Stomp Battle: Practically every time he fights someone, it ends like this. There is one time when Storm gives him pause, but even that was brief.
- Egyptian Mutant Speaks English: Possibly justified when Xavier is communicating with him mentally, but later we see him speaking plain English even though he was sealed before the language even existed, unless he picked it up from his followers.
- Freudian Excuse: Abandoned at birth due to his obvious mutations, adopted by a tribe of violent raiders who imparted their "only the strong are worthy" ethos that later became a defining element of his character, saw his entire tribe killed and also saw his adoptive father die in front of him not long after as a result of Rama Tut's attempts to find him and kill him... his formative years definitely weren't pleasant. He's still an absolutely vile being, but it's not hard to see how he became as awful as he is.
- Irony: Is defeated by the very Mutant he exploited to regain power (Rogue) and finish releasing himself.
- Knight of Cerebus: He shifts the narrative to a much more dramatic tone once he appears, due to being the most powerful Mutant introduced in the series (to the point he effortlessly defeats Storm and Magneto), and his plan to convert the planet's humans into mutants would most likely result in at least half of the world's population dying.
- Light Is Not Good: He appeared as a divine glowing godlike pharoh in his first appearance and his given name is associated with the light and is a villain.
- Meaningful Name: His given name is translated as "The First One" - as he's the first mutant.
- Mind Control: Pulled this on Storm, Professor X, Mystique, and Magneto to make them do his bidding as his Horsemen.
- Physical God: He's basically untouchable, as long as he's aware and not occupied with something else.
- Putting it simply; he grabbed Rogue and drained power from HER, not the other way around.
- Powered Armor: Advanced armor that enhances his already formidable superpowers and possibly granting him new ones.
- Psychic Powers: Telepathy and telekinesis. At the very least his psychic defenses are formidable enough to make even the likes of Professor X think twice about trying to read his mind.
- The Quiet One: In contrast to other versions of the character, this one hardly ever speaks at all. It makes him all the more creepy.
- Sealed Evil in a Can: He was sealed in a sarcophagus below a pyramid many thousands of years ago.. Mesmero enslaves Rogue to use her abilities to free him.
- Smug Super: It becomes apparent when he speaks to Xavier, all captivated by a smirk.Apocalypse: Hmph. Since when has mankind ever known what it needs?
- Story-Breaker Power: He's nearly invulnerable, can fly, and has an impressive list of abilities. He's strong enough that he defeated Storm and Magneto, two of the series' most powerful mutants, with very little effort.
- Technopathy: His Powered Armor lets him interact with and take control of virtually any computer system that he wishes to.
- Teleportation: One of the abilities he has that's confirmed to be technological rather than biological in nature.
- Training from Hell: His entire childhood was basically this at the hands of his adoptive father Baal.
- Visionary Villain: His plan was horrific in its scope and cost, but you can't deny the man has vision.
- Well-Intentioned Extremist: He sincerely believes that what he's doing is best for humanity, and as mentioned above, he doesn't care if humanity doesn't agree with him.
Code Name: Mesmero
Real Name: Unknown
Voiced by Ron Halder
"You don't know who you're interfering with here..."Apocalypse's servant; whether a mutant, a mystic, or something different is unknown, but he possesses psychic abilities that allow him to confront even Xavier on his own level. Believing himself to be a servant of destiny, he manipulated both the X-men and the Acolytes to steal the three keys to Apocalypse's prison, expecting to be rewarded by being made his right hand. Instead, upon gaining his freedom the ancient mutant withdrew his minion's powers and left him to his fate.
- Arc Villain: Of Season 3, due to being the one who is trying to free Apocalypse.
- The Dragon: To Apocalypse: while Mesmero is much weaker physically, he has the advantage of being able to move freely.
- Evil Is Not a Toy: Which he learns when Apocalypse abandons him.
- Mind Rape: Mesmero introduces himself to the audience by turning a sleeping Jean's dreams into nightmares.
- Power Tattoo: Those green patterns on his face.
- Strong as They Need to Be: Probably literally; whatever his own abilities, Apocalypse is clearly enhancing them, so that Mesmero's psychic strength varies from episode to episode depending on how much power Apocalypse is letting him use.
- Villain Decay: The X-Men easily capture him in his last appearance, due to him no longer being augmented by Apocalypse.
Code Name: X-23
Real Name: Unknown (named Laura Kinney in the mainstream comics)
Voiced by Andrea Libman (X-23) and Brittney Irvin (Target X)
"Protect me? I left to protect you!"Trained from birth by HYDRA to become the ultimate weapon, X-23 underwent the same Weapon X modifications as Wolverine, being given his healing factor and adamantium bones and claws. She escapes, breaks into rival spy agency SHIELD and researches the X Men, before stalking the students over the institute. She begins capturing all of them in a bid to lure Logan into a confrontation, believing him to be responsible for what was done to her. Logan convinces her that he, too, is a victim, before chasing her off so that Nick Fury wouldn't find her.She would later appear after HYDRA captures Wolverine, where the two would work together in a bid to survive as Logan tries to talk X-23 out of seeking revenge.
- Action Girl: She took out all the X-Men save Wolverine, and only because he got her to see sense after she made him run for his life. Yes, she sent frakking Wolverine running.
- Ambiguously Brown: Despite being a clone of Wolverine who is white, X-23 has a much darker complexion, with features that have been interpreted as anything from Latina to First Nations. It's explained that the Wolverine DNA sample was incomplete, so Dr. Deborah Risman used some of her own DNA as well.
- Word of God states that her features were based on those of the girl — who is ethnic — who modeled for the reference shoot as a thank-you.
- Antagonistic Offspring: Towards Wolverine in her first appearance. She blamed him for HYDRA getting the idea to put her through the Weapon X program. It's very much played as an angry daughter attacking her father.
- Berserk Button: She gets very pissed if someone calls her a child or a kid, as it reminds her of the childhood she didn't have.
- Big Brother Mentor: Inverted, the younger X-23 tries to play this to Logan.
- Bizarre Sexual Dimorphism: Her claw arrangment was intended to be this according to Word of God, with her foot claws specifically designed to be a trait of females with the same mutation as Logan. As described by Craig Kyle, the concept was that of a lioness; front claws for hunting prey, rear claws for self-defense.
- Broken Bird: Naturally, when HYDRA tried turning her into a weapon from childhood.
- Canon Immigrant: Was quickly brought into the mainstream Marvel lineup.
- Coming full circle when her outfit from the cartoon becomes available as downloadable content for her character - which is based on the comics version - in Ultimate Marvel vs. Capcom 3.
- Dark Magical Girl: Despite her powers being not magical, her personality and backstory fit it to a T.
- Distaff Counterpart: To Wolverine.
- Disney Death: She fakes her death blowing up HYDRA in a bid to evade SHIELD.
- Gone Horribly Right: HYDRA sure got what they wanted alright, except she was so full of rage she would try and destroy them even before escaping. After Logan X-23 intends to kill everyone working for them.
- Good Is Not Nice: After saving Logan in her second appearance she interrogates him at claw point, before trying to force him to leave, whining that he hasn't healed and allowed a tracer to be placed on him, before trying to chase him off. This is all because she's scared he would be killed when she wipes out HYDRA.
- Guile Hero: She outsmarts everyone: SHIELD (breaking in and gaining information on the Institute,) Xavier (he finds her genuinely upset and allows himself to get close enough to be taken out,) the X-Men (the only one not taken out is Logan), HYDRA (she tries to fight Logan off from following her because she wanted to be captured so she could destroy them) and Logan himself (making him think she was on a suicide mission so that SHIELD won't come after her.)
- Healing Factor: And she bitches out Logan when he doesn't heal as fast as she does."Gimme a break kid, I started the morning by falling out of an airplane."
- Which is actually Fridge Brilliance considering that in-canon Wolverine's Healing Factor is actually weaker due to the fact that its constantly healing him from metal poisoning as a result of having metal bones. So of course she heals faster as her own healing factor isn't impeded by roughly 300 lbs of indestructible metal.
- I Will Protect Him: Turns out this was the reason she was so antagonistic towards Logan when she was being hunted. She didn't want him to be a target for Hydra. She also didn't want to risk killing him when she destroyed HYDRA.
- I Work Alone: She keeps shoving away Wolverine when he tries to help. Turns out it's not only because of the threat from HYDRA or SHIELD, but she intends to kill off HYDRA and Logan might get in the way.
- Junior Counterpart: To Wolverine, with all the same powers. She even joins the Future X-Men, taking Wolverine's place on the team.
- Laser-Guided Tykebomb: HYDRA wanted to create the ultimate weapon based on Wolverine. They got more than that, a young girl who ends up bossing Logan about so he won't be caught up in her Roaring Rampage of Revenge.
- Little Miss Badass: She's even smaller than Wolverine (though to be fair his height is Retconned at times,) and given her performance could maybe have taken on Apocalypse, Galactus and Onslaught had she been around.
- Opposite Gender Clone: Of Wolverine. She has the same genes and powers as him, but she's a lot younger than him. Their age gap creates an Intergenerational Friendship between them.
- Psychotic Smirk: Flashes one to Madame Hydra who did the experiments on her, after calmly setting explosives that will kill them all.
- Roaring Rampage of Revenge: Against first Logan then HYDRA.
- Scarily Competent Tracker: She acts stupid and antagonistic when on the run. Emphasis on acts, she had wiped out most of HYDRA and planned to get captured so she'd have a clear run at the supreme commander, or she would have had a clear run had she got Logan to leave her alone.
- Tomboy with a Girly Streak: Implied. When infiltrating Jean's room, she acts girly with her teddy bear before showing a dislike to her perfume.
- She does have Wolverine's ultra-sensitive sense of smell. Sniffing the nozzle on impulse was probably like sticking her head in a bucket of Chanel.
- You Are Number 6: X-23 was the only name she was ever given in her two appearances. But Word of God has stated that she would've been named Laura Logan.
"You're with the Morlocks, we understand you."The Morlocks are a secretive group of underground mutants whose mutations make them unable to live unnoticed on the surface. When the group first appears, their survival is being threatened as the waste from a sports drink being dumped into the sewers is unintentionally poisonous to mutants. To stop the dumping, they repeatedly break in to taint the batches and are aided by Spyke/Evan Daniels who was rescued after being poisoned. When his mutation starts to become more obvious, he chooses to stay and become their champion.In the fourth season they appear in a single episode where they are still living in the sewers trying to survive the anti-mutant uprising by staying hidden, but appear on the surface after being directly attacked by Duncan Matthews to defend themselves before returning to hiding.
- Adaptational Attractiveness: Callisto. In the comics and most other depictions, she is extremely butch and is covered in scars, whereas here she's more of an Amazonian Beauty, despite her claims that she, like the other Morlocks, is too deformed by her mutation to be able to live above ground.
- Adaptational Heroism: Callisto again. In her comics debut she was a sadistic bitch who abducted Angel and planned to keep him as her love-slave. Here, she's compassionate, even sweet, and did abduct Evan, but only to cure him of the poison he drank and offer him(with his newfound extra-spikiness) sanctuary.
Code Name: Juggernaut
Real Name: Cain Marko
Voiced by Paul Dobson
"What are you trying to do? Embarass me to death? Come on, gimme your best shot!"Xavier's half-brother (as opposed to step-brother). Unlike in the comics, where his powers came from a magic gem, here he's mutant whose powers were dormant before being mystically awakened. Put in prison by Xavier due his destructive nature, he utterly despises him.
- Evil Is Hammy: "I'M RAAAAW POWAAAARH!!!"
- Evil Is Not a Toy: Mystique lets him out of jail to kill Xavier and hopes it will help her steal Cerebro. It might have worked fine if she didn't go insulting him when he didn't obey her.
- Generic Doomsday Villain: In his second appearance, he doesn't have any real motive for anything he does and just wreaks random destruction for no apparent reason, not even mentioning Xavier despite killing him being his original goal in his first appearance.
- The Juggernaut: As usual, there's very little that can stop him when he gets moving. He takes on the X-Men and the Brotherhood at the same time and keeps moving. He's only stopped by multiple psychic attacks from Xavier when they remove his helmet.
- Nigh Invulnerable: Nothing seems to have any ability to physically harm him.
- One-Man Army: When he first was released from prison by Mystique, Storm actually created a mass of fog to make sure that the police and the army could not find him, because Xavier was concerned about the army being in danger if they attacked him, not the other way around. From his second appearance, that doesn't seem to be an exaggeration.
- Related in the Adaptation: Juggernaut and Xavier are changed from step-brothers to half-brothers.
- Super Strength: The most of any character in the series.
- What Happened to the Mouse?: Gets tossed away by Rogue after draining his strength, followed by Iceman encasing him in ice as he's falling down into a dam and he isn't seen again.
Massive robots created by Bolivar Trask to hunt down and capture mutants. One was enough to provide an even match for the X-Men, Brotherhood, and Acolytes before eventually being taken down. More were built by SHIELD to fight Apocalypse.
- Adaptational Badass: Sentinels in most other continuities are more or less disposable Giant Mooks. The versions in this show are far more powerful and weaponized, to the point that the first prototype in the series is enough to give the X-Men serious trouble, and three completed variants are able to harm Apocalypse before being defeated.
- Broke Your Arm Punching Out Cthulhu: A trio of them were the first opponents to hurt Apocalypse, which is something even Magneto failed to do. Unfortunately, he proceeded to rip them apart.
- Crush. Kill. Destroy!: Their programming isn't very sophisticated.
- Knight of Cerebus: The prototype's fight with the X-Men exposes the existence of mutants, and leads to the capture of several members.
- Made of Iron: The first Sentinel wouldn't stop fighting no matter what. A projectile from Spyke, Storm's lightning and a grenade tossed by Kurt wouldn't slow it down. It's his own missiles hurled back at him by Magneto that finally destroyed it.
- More Dakka: Each one carries an enormous amount of firepower, enough to damage Apocalypse's pyramids and fight the Four Horsemen.
- The Voiceless: Unlike their comic book counterpart and most versions, they do not speak.
Voiced by Dale WilsonThe second principal of Bayville High (the first, Ms. Darkholme, aka Mystique, had vanished at the end of the first season. He carried suspicions about the mutant teens which became full-blown prejudice when they were publicly revealed, causing him to make reforms at the high school. Later, he ran for mayor of Bayville competing with the falsely heroic Brotherhood for media attention, a nod to his career as a politician in the comics.
- Adaptation Name Change: In the comics, his first name is Robert, but it's changed to Edward here.
- Asshole Victim: He gets threatened by the Brotherhood into leaving them out of his anti-mutant campaign in "No Good Deed". Considering that he's a bigot who treats mutants like crap (and also encourages others to do so), even when they save his life, it's hard to feel any sympathy for him.
- Dean Bitterman: He already had some of this on earlier seasons, but by the end if you happened to be a mutant on his campus, he turned it Up to 11 — removal of any recognition you may have gotten through "cheating" with your mutant powers (even if said charging is wholly unfounded), treating you as if you had a disability (if not worse), looking the other way on Bully Brutality of mutant students, the works.
- Fantastic Racism: The man doesn't even try to disguise his hatred of mutants when they are publicly revealed, and pretty much looks down his nose at any of them every time he talks, even ones he used to consider ace students (like Jean Grey).
- Mythology Gag: In one of the final arcs, he made mention of running for Mayor with an anti-mutant campaign focus.
- Tyrant Takes the Helm: Whatever other flaws Mystique may have had (because of being Mystique), she never (well, blatantly) exploited her rank as principal to make students' lives hell (not even Xavier's).
- Ungrateful Bastard: He doesn't show any gratitude towards the X-Men for saving him from the Brotherhood, instead talking about how he'll have all mutants thrown out of Bayville.
Voiced by Vincent GaleA jock who attends Bayville High and is Jean's first boyfriend for the first two seasons, until she breaks up with him at the beginning of the third season. He later starts terrorising mutants.
- Amicable Exes: Averted when he and Jean confront each other in "Uprising". They both state that they're glad to be rid of each other; he specifically states that he doesn't want to listen to her any longer.
- Canon Foreigner: He's a character original to the show.
- Fantastic Racism: It's one of his defining traits from the third season onwards. He even refers to Jean's powers as a "problem" when trying to reassure her that he's okay with them, which leads to her breaking up with him. He only gets worse in the fourth season, as he leads witch hunts against mutants, even attempting to shoot a mutant child.
- It's All About Me: When trying to reconcile with Jean, he says that he's willing to overlook her "problem"... as it means that she can help him cheat on his tests.
- Jerk Jock:
- He antagonises Scott whenever he can after the existence of mutants has been revealed to the public. One notable instance occurs after Jean breaks up with him.
- He gets worse by Season 4, as he starts terrorising other mutant students.
- Laser-Guided Karma: He and his fellow bigots are taken into police custody after attacking mutants in "Uprising".
- Never My Fault: He blames Scott for Jean breaking up with him, even though it was his insensitive remark about her powers that did it as mentioned under "Fantastic Racism" above. Scott even calls him out on it:Yeah, blame it on me, lunkhead.
- Would Hurt a Child: In "Uprising", he's about to shoot Leech, who's just a little boy who happens to be a mutant, forcing Spyke to take the energy blast.
