I HAVE ALL THE MUTANT!AU HEADCANONS.  Listen, children, Auntie Moran has been an X-Men devotee since she was very wee, I have mutant AU headcanons for basically everything I’ve ever seen.  I think we’ll just do headcanons for this rather than a fic, though, you can hit me up later if you want actual plot.

Okay so I’m thinking that the Mutant Registration Act is going to have to be the big issue Les Amis are protesting–they’ve got to have something to be against, it’s Les Amis for God’s sake.  And I’m thinking that a number of them are in a peculiar position because a lot of them are from wealthy upper-class families and have invisible mutations, so they could have just gone on with their lives without ever telling a lie.  This is probably vaguely modern–hell, maybe the X-Men are kicking around somewhere.  Aaaaanyway, here, it got long.

• Enjolras can glow.  Actually it’s called electromagnetic manipulation, and he can do more than glow, but that’s the most common manifestation–when he’s impassioned or excited or angry, it’s as if particles of sunlight coalesce around his skin, a harsh and brilliant golden-white halo.  He can control it, but it takes some concentration.  With some practice, he learned to do other things with light, like setting off bursts of light to catch the attention of a crowd or throwing lightning-bright flashes from his hands to baffle the police and hide their escape.  It’s beautiful, watching him speak at the Musain or at a protest, his whole body outlined in not-quite-blinding light so that there isn’t a single shadow on him, like an angel or an ancient god.  It’s why Grantaire started calling him Apollo–god of the sun, of rapture and beauty, of eloquence and elegance.  It drives Enjolras up the wall, but Grantaire persists and Enjolras’ light is all the brighter in the heat of his anger.

• Combeferre has a small psychic ability, although not in the sense of reading minds.  He can share senses, specifically vision–look through the eyes of another animal.  He likes moths and butterflies for this, because as calm and logical as he usually is, Combeferre is creative and loves art and moths and butterflies have five color receptors rather than three, they can see a whole spectrum humans can only dream of.  When he’s drunk enough or exhausted enough, Combeferre will sit with his head on Courfeyrac’s shoulder and try to describe the other colors he can see through their eyes.  (He has absolutely never started crying about it, and anything Courfeyrac says to the contrary is nothing but lies and slander.)

• Courfeyrac is an empath.  I think I’ve used that one before, but I am VERY committed to Courfeyrac being an empath, y’all can fight me at dawn on that.  He’s not much good at projecting, he can only manage it in a moment of strong emotion, although once he does manage it, he can swamp everyone around him and send them reeling into hysterical sobs or blind rage or, on one memorable occasion involving Combeferre, pure blazing lust.  (They don’t talk about that one much, it’s a bit of a Noodle Incident, but suffice it to say Enjolras reacted…poorly, when they came out of it and he realized he’d kissed Grantaire.  It was a messy week until he apologized for his reaction.)  Courfeyrac is much better at receptive empathy, at reading the people around him, and he’s a master at balancing it all, knowing which emotions are his and which aren’t.  It does make being around Enjolras a little exhausting, with all that fiery passion roaring through him all the time–Combeferre, much steadier in nature, is a good balance, though.  That’s part of the reason Courfeyrac likes Gavroche so much.  He’s not a complex kid, he’s very direct and up front with his thoughts and emotions.  It’s restful to be around, unless you’re on his hit list.

• Bousset’s mutation is probability manipulation.  Nothing so large-scale as the Scarlet Witch–he’s not going to be rewriting reality any time soon, nor eradicating mutant-kind–and instead of being able to shoot bolts, he can sort of attach it to people like a curse.  It’s relatively shortlived, but he can grab someone, skin-to-skin, and attach his power to them for a while, giving them ‘good luck’ or ‘bad luck’ depending on his preference.  Problem is, entropy demands a balance, so he deals with the backlash–if he makes someone lucky, he deals with correspondingly strong bad luck until his power falls away from them, and vice versa.  He’s always having runs of really terrible luck because he’ll tag (he calls it ‘tagging’ someone) his friends with little drips and dabs of good luck whenever they’re having a bad day or a rough week or he’s feeling particularly affectionate, and little drips and dabs add up really quick when you’re doling them out to almost a dozen people.  (He did very quietly make an arrangement with pretty much everyone except Joly and Musichetta, tagged all of Les Amis with bad luck, waited for his luck to turn up, and then went and asked the pair of them if they wanted to date him.  They haven’t let him forget it yet.  They said yes.)

• Joly’s a healer, of course.  More specifically, he can alter physical functions on a molecular level through physical contact, which means that he can do anything from cure cancer to cause someone’s body to break down where they’re standing.  He’s a little wary about physical contact, consequently–it’s never happened, but he worries that if he’s touching someone when he’s angry or scared he might hurt them.  But he always kisses Bousset’s bumps and scrapes better–literally–and he aced the fuck out of his anatomy and physiology classes.  He loves medicine, really loves it, because yeah, he can make all this stuff happen at hyperspeed, but it’s so cool to learn how it works.  He can’t heal himself, though–he could, but there’s a mental block that he can’t get around, because when he first broke his leg and tried to heal it, it didn’t work, so he’s convinced himself it’s impossible.  The limp doesn’t bother him, most of the time, but every once in a while he sits there and chews on his lower lip and wonders what went wrong.

• Musichetta can draw the future.  She’s a talented artist, and she likes to work in paints when she has the money–some of her paintings were hung in a gallery and Bousset drenched her in good luck that first time, so she does pretty well for herself, and can work in oil paints more often now.  She and Grantaire have very different styles–he has a warm pre-Impressionistic style, real and living and firelit, where she paints with sharp contrasts and comic-book-esque figures and buildings–but they love to look at each others’ work, and they tease each other about the paint splotches left on their skin after a day in the studio.  She has a whole sketchbook full of pencil sketches of the future–waste of good paints, she says dryly–and it travels everywhere with her, always ready to be yanked out when she feels a flash of insight coming on.  She saves the lot of them from being arrested almost monthly, and there was one time where she saw a train wreck and called the company in a panic, and they found a loose bolt that would have come free and killed everyone on board.  It doesn’t always go that well, though–Joly lets her curl up in his lap when she can’t stop a vision, and she’ll put her head on his shoulder and cling to his shirt, Bousset’s hands gentle and soothing down her back, until she feels better.

• Feuilly is easily spotted as a mutant, because his skin is streaked in places with smooth, beautiful black scales.  They arch over one of his cheekbones, down the line of his spine and up the inside of one of his wrists.  It’s snakeskin, black mamba specifically, and he has a host of other tricks up his sleeve–he’s never felt the need to find out if he’s venomous, though.  Black mamba venom is one of the most lethal in the entire world, and he’s just as happy to never know.  But he can sense heat, taste/smell/something in between infinitesimally small particles and his skin is so sensitive that he can feel the print on a page or sense the change in vibration when an engine is low on oil.  He works as a mechanic, because he can turn on a car and put his hands on the hood and feel and smell and sense, and know what’s wrong in no time flat.  His coworkers are generally proud of his brilliance (he’s also working toward graduating summa cum laude with a Master’s in Engineering) but every so often they get a customer who’s an A-grade dick.

• Bahorel is a muscle-mimic–he can watch someone do something physical and replicate it perfectly.  He uses it for what he calls ‘cheap tricks’ more often than not, like the time he watched Feuilly fold a paper crane and settled down to folding a thousand of them.  (He gave them to Feuilly when the man came in with a bruise on his face, his scales raw as if someone had scraped them along the ground, and won a smile before Joly pounced on Feuilly to heal him.)  But it makes him unspeakably useful in a tight spot, because Bahorel’s spent so much time watching how the police fight in a riot that he can use it against them like it’s second nature.  He’d almost rather die than watch any of the others get banged up, and Joly spends almost as much time healing him as he does Bousset, just because Bahorel has no apparent self-preservation instincts to speak of.

• Jehan can talk to plants.  He’s like Layla from Sky High and I have no shame about that comparison.  He wears cuttings of flowers in his hair and they’ll grow through his braid and bloom happily and just kind of live off his energy until he puts them in dirt, and when he’s feeling particularly effusively affectionate tendrils of his plants will reach down his arms toward whoever’s closest to him.  Also, he’s normally very gentle and his plants are all pretty flowering vines and dandelions and things, but when shit gets serious during a protest or on the street, everyone is reminded very quickly that tree roots can crack open mountains.

• Grantaire can animate shadows.  He’s one of the unlucky ones–anyone can take a look at him and know he’s a mutant, his eyes glassy black and his curls shifting as if in a low wind as the shadows shift on his skin.  He’s been told all his life that it’s ugly, that the way the shadows curl lively along his jaw and under his curls and beneath his brows.  It’s useful sometimes, being able to summon a shadow army to get between the police and the fleeing Amis, or being able to animate a sparring partner out of his own shadow, but Grantaire is always the first one to call Enjolras out on being naive.  Easy to talk about how humans will trust you when you look like an angel–less so when you deal in darkness.  Enjolras is perpetually furious with Grantaire’s cynicism, but he’s more furious with the world that created him, that convinced him that his mutation is something ugly and irredeemable.  He thinks (but never says) that Grantaire’s shadows are beautiful, like ink spilled over his skin, and once they finally work their shit out (Gavroche is the one who makes it happen, probably, because he’s a sneaky little shit), he discovers that Grantaire can let his shadows spill on Enjolras’ skin, leaving dark pools against the golden radiance.

• Gavroche and Eponine (and Azelma, wherever she is) have a modification of the same mutation, which is, according to Thenardier, the only reason he knows they’re all his children.  They’re all pyrokinetics, although at different levels–Gavroche is a manipulator, able to shape heat and fire into any shape as long as he has something to work with, and Azelma is a firestarter, but Eponine is the only one of them who can do both, just like their father.  They’re all easy to spot as mutants, too, with eyes that flicker red with flames when they catch the lights and core body temperatures well north of 200 F.  She’s terrified that somehow her power’s going to corrupt her, turn her into Thenardier, and Marius is the first person who shows nothing but pure delight at the sparks that crackle out of her hair and the flames that lick her fingers.  She can’t help but love him a little for that.

• As long as we’re on the subject, Patron-Minette.  Montparnasse’s mutation is 100% out of his control, he can’t turn it off or strengthen it at all.  When asked, he tells everyone his mutation is being beautiful.  In reality, he doesn’t really understand it, but it’s something to do with pheromones–just about everyone who sees him, who draws close enough to talk, is clobbered with a metaphorical two by four of attraction.  It’s very useful in the killer-for-hire business, and he’d never admit how uncomfortable it makes him sometimes.  Eponine, her skin always just this side of burning, is one of the only people unaffected, and he’d kill to keep her around.  Claquesous is a teleporter, and Babet is a metamorph, able to look like anyone he wants, and Gueulemer has superstrength.

• Marius isn’t a mutant.  He did get booted out of his grandfather’s home and disinherited for starting a fight in polite society about mutant rights, though, so Bahorel and Courfeyrac take to him immediately.  But he also had the misfortune to walk into a conversation about the concept of a mutant ‘cure’ and open with “Well, some mutants might need it” and that went over a treat.  He managed to redeem himself, though, although Enjolras eyed him with suspicion for a while.

• Cosette!  My sweet girl!  Has wings!  They’re not the crisp white wings of an angel or a dove, either–they’re broad and angled and bronze fletched with dark red, the wings of a hawk.  She normally hides them by binding them down under her clothes–her mother had wings too, she remembers vaguely, wide and soft and wheat-pale as a songbird’s, and it was Mama who taught her to bind them down, hide them, before she went away.  Marius saw her for the first time with shed feathers braided into her hair until she looked like a spirit from another world, and she’s strong enough to take him flying (bridal style, of course).

• Valjean’s not a mutant, but Javert is.  He’s also neck-deep in denial.
