the blocked out parts is how their species reproduce. spoiler alert pyrovulcans don’t engage in coitus they just slap their flames together and a baby is “forged” like a weapon. it’s not THAT simple a process but that’s the tl;dr. pharmos dragons are seahorses except the men have the eggs and the women have the semen and carry the baby — and lepirs just do what chickens and roosters do.

by the way,

SPINNER

he’s a dragon.. if dragons looked like aliens. an outcast because he’s both short and stout compared to many of his race, they live on a habitable rock too small to be called a planet.

on top of his build, he’s got both defective wings and flame ducts — what resulted was an all around stronger physique and unusual physical prowess given much less reliance on his wings than others AND his home planet having more gravity.

their muscles behave weirdly, they don’t deteriorate when left unstimulated, but spinner can’t gain muscle until those muscles truly strain — given his planet’s conditions, it’s hard to find those or even things physically stronger than him.

he’s learned to play dirty against those who have the high-ground. his weapon is quite literally a HUGE LASER GUN, his fists and/or some daggers.

DABI

a pyro-vulcan (that’s what i’m naming their race but he’s just a fire guy) entirely flame based. oxygen is mandatory.

genetics made his flame output much too strong for his body to handle; in short bursts he can use his flames, but long, drawn out encounters waste his flames and harm him. he has flames for hair and his body but those are not optional features — oddly enough, he doesn’t burn to the touch, he’s only unusually warm.

all vulcans reach the end of their life solely because their body has used up all of its combustible energy — for dabi and his unusually hot flames, his death will come MUCH sooner.

his flames are his weapon, and at their highest can deadassuinely cause a supernova — the downside is that he dies along with. and his allies die. and a whole solar system dies.

he (physically) can workout, but too much strain will make his body combust unnecessarily, he prefers not to waste any more of his short life — so he does the bare minimum (twink by choice).

SHIGARAKI

a moth-like alien, born with an uncontrollable urge to destroy. it started with small things: taking apart gadgets, tearing clothes and furniture, but as his people lost patience for his behavior, he tried to repress it.

the thing is about repression is that it makes urges stronger, and with his alien race, strong emotions can manifest abilities, but cases planet-wide are rare.

with his heavily repressed urge to destroy unleashed, he manifested decay. his hands are his weapons, whenever he hones his skills in decay, his body gets stronger to accommodate, but there’s a cap.
