open/close all folders
Code Name: Cyclops
Real Name: Scott Summers
"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.
- Big Brother Instinct: Very protective of his long-lost little brother, Alex.
- Additionally, he's protective of the younger mutants, particularly Kurt.
- The Captain: And a badass one at that. This is easily one of Scott's most badass depictions yet.
- Cool Shades: Used to help control his powers.
Code Name: Unknown
Real Name: Jean Grey
"It bugs me to always be treated like the weaker sex!"
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.
- Impossible Hourglass Figure: Nice, uh, pants, Jean.
- Mind over Matter: Her powers are telepathy and telekinesis.
- Moral Guardian: 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.
- Red Oni, Blue Oni: The blue to Rogue's red.
- Spoiled Sweet: She possessed everything that can make a girl the Alpha Bitch. Beauty, popularity, and a jock boyfriend. Instead she was nice and willing to help anyone.
- Straw Feminist: Comes up during Walk on the Wild Side and never really touched on again. She calls Scott out on trying to help and bitches at Duncan for buying tickets to a dance, when its supposed to be the girl who asks the guy out, while complaining about always feeling like she's treated as the weaker sex.
- 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
"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.
- Happily Adopted: Played with: 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.
- 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
- 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.
- Shout-Out: He's the only X-Man to wear his original costume from the comics.
- 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)
Code Name: Rogue
Real name: Unknown
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 Rogue 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 accepted that Scott loved Jean and not her.
- American Accents: Dixie
- All Love Is Unrequited: Her love for Cyclops can never be returned. (Same with 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.)
- Anti-Villain: Was this when she was a member of the Brotherhood.
- Badass: 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.
- Bare Your Midriff: A good majority of her outfits, especially her season 1 civilian outfit.
- 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 opponents, and then proceeds to use those to take care of the rest of them. Or if one of her friends are knocked out anyway, she takes their powers as an extra boost to the group's fighting strength. She definitely uses it much more liberally not to mention more effectively than often portrayed.
- The Chick: The first brotherhood chick.
- 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.
- Heel-Face Turn: She first joined the Brotherhood before joining the X-Men.
- Hopeless Suitor: For Scott.
- Most Common Superpower: again, it's Rogue.
- 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.
- Red Oni, Blue Oni: The red to Jean's blue.
- 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 Ship Tease with Gambit, plus scattered moments in other episodes.
- Though, according to the character designed and occasional director of the series, they kept this to a minimum because a lot of the writing team shipped Scott and Rogue.
- 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: 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.
- 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 thilled 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.
- Cute Clumsy Girl: The only class she doesn't ace is gym.
- Dating Catwoman: With Avalanche.
- The Ditz: She started as one, but this mostly stopped after the first season.
- Ditzy Genius: She's shown to be well versed with the Mansion's computer system, and was stated to be a straight A student. So its more that she just acts a little ditzy.
- Drives Like Crazy: Her driving even scares Wolverine, due to her habit of phasing the car through obstacles. Scott was so scared he swore to never drive again.
- Informed Judaism: The only evidence that she's Jewish is a scene of her lighting the menorah in her home in the Christmas Episode.
- 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.
- Morality Pet: Since season two on, definitely Lance's.
- NaÔve 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.
- The Smart Girl: She can be a brainiac sometimes.
- Teen Genius: A straight A student (although her intelligence was somewhat downplayed compared to other versions of Shadowcat).
- Valley Girl: She stopped, like totally, after the first season. For sure.
Code Name: Wolverine
Real Name: Unknown, goes by Logan
"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
- 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.
- 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.
- 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 just gotta let kids 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.
- Wolverine Publicity: Subverted. Amazingly, Wolverine was mostly a background player due to being an adult on a show where the focus was on the kids. And it worked pretty well, mind you.
- The Worf Effect: Need to make The Juggernaut look like a huge threat? Have him kick Wolverine's ass.
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
Code Name: Beast
Real Name: Hank McCoy
"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.
Professor X/Charles Xavier
Code Name: Professor X
Real Name: Charles Xavier
"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.
- Friendly Enemy: How Xavier sees Magneto, although their friendship is not as emphasized as in other portrayals.
- Non-Action Guy: Justified since his power is telepathy. He could perform Mind Rape and the like, making him a destructive force, if he wasn't so moral.
- Parental Neglect: Subverted in regards to David/Legion. He didn't mean to be neglectful, he didn't know the kid existed!
New Mutants/New Recruits
Code Name: Iceman
Real Name: Robert 'Bobby' Drake
Voiced by Andrew Francis
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. YMMV on whether or not he's the coolest
new addition or the Too Dumb to Live
Scrappy who ruins the series (Thought primarily the first option to the less crazy fans).
- An Ice Person: What did you expect?
- 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 to learn his full potential.
- Character Development: Starts off as nothing more than an extra face. By Season four, he officially replaces Evan's role in the series, getting to hang out with the main X-Men.
- Heterosexual Life-Partners: With Cannonball.
- The Hero: To the New Recruits anyway.
- Too Dumb to Live: He stole the X-Jet for a joyride, broke into the danger rom for unsupervised training, and put an iceberg in front of the ship he himself was sailing on.
- Totally Radical: To some extent, not as bad as Spyke though.
Code Name: Cannonball
Real Name: Samuel 'Sam' Guthrie
Voiced by Bill Switzer
The tall, blond southern boy who joined at the same time as the other New Recruits. More well rounded and likable than Bobby in some terms, 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 land.
- 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.
Code Name: Jubilee
Real Name: Jubilation Lee
Voiced by Chiara Zanni
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, 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 Aquilla
Voiced by Alexandra Carter
The only one to get an episode of focus (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
- Race Lift: She's actually from Brazil in both show and comics, but her comic appearance had her as a blue-eyed Caucasian 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 Strand
A Scottish mutant who can turn into a wolf or half whenever she wants who primarily spent her appearances in the background or as a wolf, but got an episode or two speaking. Like Jubilee, she was written out of the series, despite being popular, thought her lack of importance to any 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.
- 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 (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 little to non-existant accent that almost sounds like the voice of a fairy.
- Ship Tease: She played around with Sam & helped Jamie with Homework which may explain her ships with them, but the most popular Rahne-related ships with Roberto, based on the episode Retreat (being the only episode 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 Coleman
A 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.
- 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.
- The Voiceless: Speaks in one episode only.
Code Name: Berzerker
Real Name: Ray Crisp
Voiced by Tony Sampson
A 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.
- 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 heís 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 himself out against STORM (who at the time was upgraded by Apocalypse).
- You Gotta Have Blue Hair: He has blond hair with a spiked, orange fringe that to most people just looks ridiculous.
- It might be dyed, though.
Code Name: Multiple
Real Name: James 'Jamie' Madrox
The youngest of the ensemble, Jamie is like the little brother none of them wanted, his power 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 really anyone's brother, but they act like it nonetheless.
- Bratty Half-Pint: A rare, non-Scrappy case!
- Cheerful Child: Hence why he's not Multiple Man like the comics.
- In Name Only: Compared to his comic self at least, Who was the same age as most of the other X-Men.
- 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 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, he was referred to as 'like 12' but this may just be an exaggeration.
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 less serious minded of the cast, regularly skipping out on meetings and acting really 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.
- 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.
- Just Like Robin Hood: After joining the Morlocks. Though he never actually steals, he partakes in Street Justice to protect mutants.
- 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.
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 home town as Shadowcat, but had a much 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.
- Adaptational Heroism: In some extent. 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.
- Arch-Enemy: Cyclops
- Berserk Button: Since Season Two on, for your own good don't hurt or threat Kitty.
- Characterization Marches On: In his first episode he's destroying his school with out remorse, as well as trying to manipulate Kitty's feeling and eventually trying to killing her and her parents. In following episodes his powers generate an Oh, Crap response to being love stuck on 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 very little to do with the comic book Avalanche outside of team affiliation. 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.
- 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.
- 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.
- Race Lift: The comics' Avalanche was Greek. Presumably he was made American to ease him fitting into the setting.
- Steven Ulysses Perhero: If you switch his first and last names you get pretty close to his codename.
- Tall, Dark, Handsome AND Snarky.
- 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
"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: This incarnation of Pietro almost lacks any redeeming qualities.
- 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.
- 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.
- 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. Itís 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 not justifies) 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. And like a toad, 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.
- Four-Man Band: The Pervert- even though he isn't really a pervert. He often alternates between being the Butt Monkey with Fred.
- 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.
- In a Single Bound
- 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 Blob/Fred Dukes
Code Name: Blob
Real Name: Fred Dukes
"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.
- 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.
The Scarlet Witch
Scarlet Witch/Wanda Maximoff
Code Name: Scarlet Witch
Real Name: Wanda Maximoff
"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.
- Ax-Crazy: When it comes to Magneto and Quicksilver.
- Fake Memories: Had these implanted by Mastermind - he basically replaced every bad memory she had of Magneto with good ones.
- Goth: Even moreso than Rogue.
- Sanity Strengthening: Ironically, became less psycho and more kind and helpful towards others after Mastermind messed with her head.
- 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 problems.
- 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 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.
- 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 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.
Mystique/Raven Darkholme (White version)
Mystique/Risty Wilde (Black version)
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 an American 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.
- 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 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.
- Cat Smile: Seems particularly fond of doing this.
- 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.
- 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.
- Failure Is the Only Option: In the first season, Mystique always lost any battle she had against Storm.
- 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.
- 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.
- 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.
- 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.
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.
- 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.
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.
Code Name: Gambit
Real Name: Remy LeBeau
"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.
Code Name: Colossus
Real Name: Piotr Rasputin
"I am not a lackey! I... I have no choice."
Piotr is pressured into serving Magneto, who had abducted his family. He appeared to have found and freed them before the end of the series.
- 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.
Code Name: Pyro
Real Name: John Allerdyce
"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.
- Jesus Taboo: His first name in the comics is St. John. The "Saint" gets dropped for the adaptation.
Code Name: Mastermind
Real Name: Jason Wyngarde
Voiced by Campbell Lane
He'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
Apocalypse/En Sabah Nur
Code Name: Apocalypse
Real Name: En Sabah Nur
"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. Milennia 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.
- Big Bad: Season 3 and especially 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 is 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 learned to pick up from some his followers.
- Irony: Is defeated by the very Mutant he exploited to regain power (Rogue) and finish releasing himself
- Visionary Villain: His plan was horrific in its scope and cost, but you can't deny the man has vision.
- Well-Intentioned Extremist: 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
"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.
- 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.
Code Name: X-23
Real Name: Unknown (named Laura Kinney in the mainstream comics)
Voiced by Andrea Libman (X23) 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.
"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 stilling 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 return into hiding.
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.
- Badass: He takes on the X-Men and the Brotherhood at the SAME time and is only stopped by a psychic attack from Xavier when they remove his helmet.
- 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 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.
- 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.
- Super Strength: The most of any character in the series.
- What Happened to the Mouse?: Gets tossed away by Rogue after draining his strength, and 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 prototype) one is enough to give the X-Men serious trouble, and three completed variants are able to harm Apocalypse before being defeated.
- Knight of Cerebus: The prototype's fight with the X-Men exposes the existence of mutants, and leads to the capture of several members.
- More Dakka: Each one carries an enormous amount of firepower, enough to damage Apocalypse's pyramids and fight the Four Horsemen.
- The Voiceless: Unlike the comic incarnation, they do not speak.
