I love when magic has an effect on the body & soul of its caster. like!! you don’t get to be a reality-bending demi-god and walk away with no strings attached. there’s always a price.
Bloom’s dragon fire consumes her from the inside, leaving lightning-like tissues of scars along her limbs - be careful, rumbles the Great Dragon from within, don’t let your emotions consume you. Bloom wails from the pain and clutches whoever is in the vicinity - but cannot fully stop it. just prevent it or treat the aftermath.
Musa gets migraines. Stella becomes ill when she doesn’t get her daily dose of sunshine. Aisha’s senses get muddy sometimes, almost as if she’s submerged underwater. Nabu experiences uncontrollable tremors in his arms, when he creates too many of his phantoms. all of those are - yes, horrible to experience but manageable enough for the school (and the Magic community at large) to tell them to just suck it up and weather through.
once you get your enchantix though, you start developing… unique abilities. almost like, in achieving the final fairy form, you became one with your brand of magic.
Bloom starts producing smoke. Like - she snorts at something funny Riven or Sky say, and literal puffs of smoke emerge from her nose. It’s jarring at first (“Bloom Peters, when did you start smoking? do you know that it kills??”) but quickly becomes endearing once they realise it’s not life-threatening in any way (after speed-running through like fifteen Magix apothecaries). Among her other ‘oddities’: too hot to cuddle with (only Stella can stand the high temperature, since she has a resistance to heat), becomes strangely overprotective and a little possessive, her eyes sometimes become a startling orange hue as if she’s embodied by the great dragon himself (it’s just a party trick).
Stella becomes more ethereal. In certain lights, her skin looks translucent - like a mirage weaved with moonlight. Her hair glints in the sun, almost too bright to like at; her touch feels phantom-like. She becomes even more beautiful, but less - human, earth-bound, Stella-esque. A curse and a blessing, that one.
Musa’s hearing gets really fucking good. She has a steadily growing dossier of blackmail on every student in Alfea - simply because shut doors or longer distances are no longer obstacles for her. It’s annoying too, because she can’t exactly turn it off - and now she gets to hear all the things people say about her, behind her. but here’s a consolation - she can influence other creature’s emotions through the melodies she hums! like how in canon, she pacified the bird Roc and brought mirth to the arguing fairies.
Flora gets much sturdier. Her skin harder than bark; her body able to withstand thirst and hunger for much longer than the rest. It’s honestly so intimidating. Here’s this sweet young woman — known to cry for trampled flowers and cut weeds!! — absolutely bodying a sharp ass ice shard that Icy attacked her with. It just — crumbles upon colliding with Flora’s body. insane and frankly so so hot for others to see.
As per the negatives… I like the idea of Flora being able to connect to the memories of nature around her and literally absorb the pain/fear/anguish of whatever she witnessed.
Aisha and Bloom are similar, in a sense that both of them are vessels to primordial divinities of their universe — Bloom is the holder of the Dragon Flame, and Aisha is the child of the Infinite Ocean. therefore, both experience a more extreme transformation than their girl friends. like, Aisha’s dreams are infiltrated by visions of past and future; memories of those who were lost to the Ocean. she dreams of Politea, of Tritanus, of her mer cousins and ancestors, and even those who were not yet born. if Aisha was not so mentally wilful, she might’ve folded under the weight of those prophesies.
Aisha can also breathe under water and her body gets the musculature it needs to be on par with her mer cousins while swimming, because why the fuck not?
Tecna - I frankly have no ideas for and would love to hear suggestions!
