Characters / X-Men: Xavier Institute

Martha Johansson / No-Girl / Cerebella

Nationality: American

Species: Human mutant

Debut: New X-Men #118 (November, 2001)

A young telepathic runaway, Martha Johansson was captured and butchered for parts by the U-Men under the direction of John Sublime, who placed her brain in a special jar to use her telepathy and power negation abilities for his own benefit. She was rescued by the X-Men, who made improvements to her container and allowed her to join the student body of Xavier's school.

• Bioluminescence Is Cool: Her blood is bioluminescent. She used it to write a remarkable suicide note.
• Brain in a Jar: All that remains of her original body is her brain, which is kept alive in a special floating containment unit that is frequently upgraded by the X-Men.
• Meaningful Rename: After finally receiving a new body at Krakoa, she changes her codename to Cerebella, because her brain is still exposed.
• Possessing a Dead Body: She briefly possesses Gabby Kinney's body while she and the rest of their group looks for a way to bring her back to life. Gabby doesn't hold it against her and they're still friends.

• Throw the Dog a Bone: After over twenty years without a real body, during New Mutants (2019) she finally receives a new body to hold her brain.
• What the Hell, Hero?: Her arc with the Lost Club is a prolonged example. She calls out how insensitive the name No-Girl is for someone totally dehumanized and reduced to brain in a jar. She also calls out the X-Men on doing nothing to help her even as their resources to do so expanded, especially after founding Krakoa.

And he's a reserved, polite, nerdy intellectual type (although he does have a very deeply repressed monstrous killing machine buried deep inside).
• Awesome Moment of Crowning: After consuming the legendary King's Egg, he has become the Emperor of the entire Brood species.
• Interspecies Romance: Broo (brood) is in love with Idie (human mutant) and in their first meeting he even proposed to her.

• Atrocious Alias: Hates being called "Kid Apocalypse", a nickname started by his classmates after they noticed his resemblance to Apocalypse.
• Good Counterpart: To Apocalypse.
• I Am Not My Father: Or rather I am not my clonal source.
• Killed Off for Real: It’s revealed in New Mutants (2019) that his death during Age of X-Man stuck and that he hasn't been resurrected due to Krakoa's wishy-washy rule about clones.
• The Matchmaker: When Bobby stumbles over asking a guy out in Paris, Evan steps in and helps get the guy's number for him.

• Odd Friendship: With Deadpool and Quentin Quire.
• Rubber Man: Inherited Apocalypse's super-stretching abilities.
• Stepford Smiler: The time-displaced young Iceman and some of his other peers note that Evan smiles a lot and seems like he is very happy. While that is mostly true, he does get depressed or worried quite often and worries that if people see any other expression on his face they will only see Apocalypse instead of him.
  Evan: Why do I smile all the time? Why don't I have any bad days? Because... what happens when my friends see the clone of Apocalypse looking sad or depressed or angry? Do they start to wonder? Do they start to worry? Do they start to fear? Who could blame 'em? Worst-case scenario with me — has always been Armageddon. I'm not saying it's all an act. I am a pretty happy guy and I like my life. I really do. But I smile — because I have to.

Iara Dos Santos / Shark-Girl

Nationality: Brazilian

Species: Human mutant

Debut: Wolverine and the X-Men #20 (January, 2013)

One of the numerous new mutants whose X-gene was activated after Hope spread Phoenix energy across the Earth. She was found and recruited to the Jean Grey School by Angel, who also saved her from Mystique and Silver Samurai.

• Animorphism: Her main ability is to turn into a shark, hence her name.
• Bloodlust: Smelling or tasting blood causes her to go berserk and lose control of herself to a certain degree.
• Dude Magnet: Guys tend to fall head over heels for her despite her being a human shark. Silver Samurai II, for whom going out with international models is a mundane activity, could only stutter around in admiration of her. Stegron and Sauron had a partnership going on but they came to blows because they were fighting over Shark Girl. Then Julian Keller (Hellion) started getting fluttering hearts around her, near the end of the comic.
• Fake Defector: Pretended to join Stegron and Sauron's plan to turn the inhabitants of New York into dinosaur-hybrids, when in fact she was looking for the right opportunity to free her teammates.
• Man Bites Man: Her go-to move in combat. In her first appearance, she nearly bit Mystique's head off and tends to threaten villains with being eaten after that incident.
• Shark Man: Well, she can turn into a humanoid shark. She eventually comes to prefer her shark form over her human one.
• Threatening Shark: She's not particularly threatening, but she can turn into a shark.

Lin Li / Nature Girl

Nationality: American

Species: Human mutant

Debut: Wolverine and the X-Men Vol 2 #1 (May, 2014)

Another new student at the Jean Grey School after Hope restored the mutant gene. Lin is a quiet student who can commune with the nature around her, a power that includes talking with and controlling animals and plants, and limited range control over the weather.

Unfortunately for Nature Girl, her connection to the Earth and its creatures eventually drives her to begin killing humans who are harming the planet as she can no longer bear to listen to the pain the world is in and thus becomes a fugitive on the run from the Quiet Council of Krakoa.

• Alliterative Name: Lin Li.
• Bald Mystic: In a 2021 Infinity Comic, she goes bald after suffering a nightmare of being punished by the Quiet Council. She claims this is a sign of her powers evolving.
• The Beastmaster: She is able to control and bond with all sorts of creatures, including the Bamfs, hellish imps who were imprinted with Nightcrawler's blood. She weaponises it by pouring the pain of an entire biome into Jean Grey's mind when the latter is trying to restrain her.
• Beware the Nice Ones: She can be downright terrifying at times, at one point recruiting a small army of rats to attack and interrogate D.O.A. Then, she goes off the deep end.
• Brutal Honesty: Although she is nice, talking with animals and plants who tend to be far more straightforward than people has made her quite blunt.
  Trevor: How are you so calm right now Lin?! What if these vultures dropped us?!
  Lin: We'd die instantly. There'd be no pain.
  Trevor: YOU'RE NOT MAKING THINGS BETTER!
• Cloudcuckoolander: Due to being better at talking to animals and plants instead of other people, many of her statements can sound confusing or make little sense without her knowledge of the world around her.
• Depending on the Artist: The size and shape of her antlers can vary significantly depending on who is drawing her. They tend to normally be around a foot long and stick sideways out of her head, but other times they are a few feet long and sometimes go straight up.
• The Empath: She can feel what animals and plants feel. She can weaponize this against telepaths by bombarding them with all the pain of a species like flies that are killed en masse on a global scale.
• Face–Heel Turn: The pain of the Earth and its creatures slowly dying to mankind's pollution and lack of care drives her mad (though it's indicated that being forced to leave the Age of X-Man reality, which for her was a paradise, the very prospect of which left her in tears, really did not help). After killing a convenience store clerk in a fit of rage Nature Girl begins a campaign to hunt down and murder polluters, poachers, and others harming the world. While some of the X-Men and Quiet Council sympathize with her rage and goal, a number of her victims clearly do not deserve death and she is very publicly breaking Krakoa's laws against killing humans.
• Green Aesop: In the X-Men Unlimited (2021) storyline X-Men Green, it's shown what she’s up to since moving to Krakoa. Despite living in a mutant paradise that she can communicate with, she’s still in pain because she can feel that the rest of the Earth is still being polluted by humanity.
• The Grinch: With good reason: an X-Men holiday special revealed that around Christmas time all she can hear are the screams of slowly dying trees.
• Heart Is an Awesome Power: Being able to talk with animals and plants, and command them to a certain extent, proves to be very useful when tracking people down or finding out details about a crime or event that happened without human witnesses. Later, her power set evolves, becoming a full fledge elemental.
• Heel–Face Brainwashing: Her turn to extremism was sparked by Curse wishing to become her friend and using her powers to make it so.
• Horned Humanoid: Has deer antlers and can use them to brutal effect like slitting the throat of a poor clerk.
• I Reject Your Reality: Her response to Gaea calling her out for the murderous nature of her vengeful crusade has shades of this.
• Never My Fault: No matter how many people, even Gaea herself, tell her that her methods to save the environment do more harm than good she rejects them all as not caring enough to do what needs to be done. She loses a lot of allies in her crusade and rationalizes their loss for her cause every step of the way.
• Out of Focus: After being a fairly prominent supporting character since her introduction, during the first couple years of Krakoa Age she was only a background character with just a few appearances. She then became the main character of the X-Men Unlimited (2021) storyline "X-Men Green".
• Pay Evil unto Evil: Some of her targeted victims include poachers who are hunting endangered animals for sport.
• Physical God: Becomes this when she moves into the Omega category in X-Men Green. Unfortunately, it coincided with her mental decline.
• "Reason You Suck" Speech: Delivers more than one on the way that mutants are doing nothing for nature, and humankind as a whole. At the end of X-Men Green, she receives a brutal one from none other than Gaea, Mother Earth herself, who points out that a) humans and mutants are her children too, b) whatever wounds they do her, they'll heal, even if they take millions of years, and there is no excuse for her behaviour, c) Lin could have been an inspiring figure who bridged the connection between humanity/mutants and the natural world, rather than a vengeful one. When Lin refuses to back down, Gaea dismisses her and says that she will walk the Earth without her blessing.
