hi and hello i'm back from the dead here are some 1b quirk headcanons (that may or may not contradict canon but i'm too lazy to check everything)

Kuroiro

dad had a very limited phasing quirk, mom had an ink quirk. neither had #000000 skin that part kinda came out of nowhere

despite obviously being connected to his ability it's just a mutation that appeared along with it and isn't required for the quirk to be usable -what i mean by this is that Monoma's skin doesn't turn black when he copies it

it's. a really confusing quirk mechanics wise. Kuroiro himself isn't exactly sure how it works, it just does and thinking about it too hard makes his head hurt lol

he can merge into dark surfaces. doing so doesn't increase the weight of the object he's merged into. it's like he straight up disappears.

when he fully submerges himself in a shadow, he finds himself in kind of a black void in which he can move freely (without using his muscles, i think. just zooms around somehow...) and which he can leave whenever he wants through the same surface he used to enter or another one connected to it. is it some sort of super limited alternate dimension that he can enter through shadows?? PERHAPS

since he doesn't lose his clothes when he uses his quirk, he has to be able to bring objects into the darkness with him. i imagine he can do it with all things that aren't living (them being black is not necessary because it seems to work with white shoes and bracelets) and as long as they're touching him - if he lets go of an object while in a shadow, it will just fall out. therefore his quirk can be used for transporting things, but not for storing them.

you can also explain him not losing his clothes by them being mirio style dna fabric but that's the more boring option so screw that

when jumping out of a shadow, his speed matches that at which he was moving inside of it. i think it would be cool if he could build up speed while moving through a shadow and then just SHOOT out of it and kick someone real hard

Pony

Pony actually has "two quirks" - the one that gives her horns and the ability to shoot them (inherited from her dad) and the one that gives her the appearance of a horse/pony (inherited from her mom). it's registered as "horn cannon" for the same reason why Tokoyami's quirk isn't "raven" and Mina's isn't "pink alien thing" - it's a passive mutation quirk so it gets "overwritten" by horn cannon, which is more "active" - does this make sense?

thanks to her secondary quirk Pony is much stronger than the average person and can run really fast when on all fours. she can also neigh like a horse, digest celulose a bit better than average and sleep while standing. it's... not much besides that

Pony's horn cannon quirk requires keratin to function, because it's what her horns are made of. regrowing her horns too many times causes her to suffer from keratin deficiency, worsening the condition of her hair, skin, nails and hooves

most telekinetic quirks cause headaches when overused, but Pony's ability to control her horns is very minor so that drawback doesn't really affect her

Kendo

her quirk is a mix of her parents quirks - her mom can extend her fingers and her dad has superhuman strength in his arms

enlarging her hands increases their weight a lot, but Kendo's abilities don't suffer from that because her back and arms are naturally extremely strong as an adaptation to her quirk (she can beat everyone in the class at quirkless hand wrestling - it's highkey unfair, but she can)

however, she still sometimes ends up with lower back pains if she uses her quirk too much

Setsuna

her dad does have a lizard quirk (that actually gives him a tail that he's able to detach and regenerate), but her mom's quirk is actually more similar to Setsuna's. it basically lets her detach and re-attach parts of her body along predetermined lines, and lacks the regenerative abilities

her quirk makes her basically indestructible because it lets her regenerate any destroyed or injured body part, plus she seemingly doesn't even need any of her organs to be connected to each other. her only weak point is her head, attacking it is the only way to knock her out (or kill her)

her head/brain is also her "core" - she can only regenerate body parts that are connected to her brain. i'll use the final exams as an example - if she managed to get her whole head outside the gate, she would be able to regenerate her whole body around it and pass (she would probably pass out from exhaustion, but still). however if she only got some other body part, like one of her arms outside the gate she wouldn't be able to do that because the arm isn't connected to the brain. hope you get what i mean lol

in-universe, her quirk probably isn't censored with black, so i'm guessing it looks quite gory and tends to freak people out when they see it for the first time. an upside to this is that thanks to having to deal with the sight of it on a daily basis, no one in class 1-B has to worry about the shock of first seeing gruesome injuries during hero work. they're all desensitized through safe means👍

a drawback that is shared by most regeneration quirks is that due to the rapid cell division that occurs when regenerating body parts, she is at a high risk of developing cancer. however that's far less troublesome than it sounds, as she can always just painlessly detach the cancerous part and grow a new healthy one. doctors hate this one weird trick or something

as you can probably tell from my art, i really like the headcanon that her skin looks kinda patchwork-y because her regenerated pieces are never exactly the same as the original body parts

due to those imperfections, she's extra careful about her brain pieces bc it's such a complicated organ that the tiniest change in its structure can seriously mess things up. like cause memory loss or personality changes, setsuna finds that terrifying and honestly who wouldn't!!

Tsuburaba

another 50/50 mix - his mom can create colorful smoke/mist with her breath and his dad can produce a glass-like liquid from his skin and solidify it at will

i gotta admit that i'm not sure what the "solid air" actually should be. if it was actual solid air, it would be incredibly cold, unless there's some pressure fuckery happening here. and since i kind of don't understand that hypothetical pressure fuckery i generally prefer to think that it's some different substance that's a solid in normal conditions and was just named "solid air" because the way it's created makes it seem like it.

while the amount of solid air he can create does depend on his lung capacity, the quirk itself doesn't give him any extra amount of it. in other words he has the lungs of a regular athletic teenage boy, nothing special

his actual "quirk factor" is his throat, using his quirk too much first dries it up, then proceeds to damage its walls, which can result in him not being able to use his quirk for a while. throat damage due to external factors does the same thing

he can make the stuctures created with his quirk disappear at will. it's not required, but he likes to snap his fingers when doing so. makes it look cooler.

he's only ever been shown to create stationary structures, but i like to think that he can also make mobile ones (in other words i think he should be able to make solid air weapons and tools because that's cool)

Tetsutetsu

exact copy of his mom's quirk. gotta go with the joke

along with the temperature resistance, inability to regulate his hardness and dependence on iron consumption, another difference between his quirk and Kirishima's is that turning into steel also significantly increases his weight, which allows him to hit harder at the cost of slowing him down a little

the wiki says that it was never clarified what "iron consumption" means, so it's up to me to decide - i think they meant that he needs to eat food that contains iron, judging by the fact that the (stereotypically!) rich in iron spinach is his favorite food. i don't think he eats the actual metal, lol

even when his quirk is off, his hair is slightly affected by it at all times, which makes it resemble thin metal wires. he styles it by bending it with his hands

Reiko

since it's an extremely basic quirk, i think she also directly inherited it from one of her parents i don't have concepts for them so idk which one oof

she can only use her quirk on entire objects, not parts of them

while she doesn't have to always keep the objects she's manipulating in her field of view, she has to see them in order to "pick them up" in the first place

i believe that the "can only lift things that weigh less than an average person" limitation she has in canon is supposed to explain why she doesn't just use it to throw people around, and yeah that makes sense. what doesn't make sense is why she can't pull them by their clothes instead, so i'm going to make up an explanation for that too - clothes are usually pretty thin, so trying to grab them without also grabbing the person themselves and therefore exceeding the weight limit usually requires quite a lot of precision, which Reiko doesn't have (yet - one day she'll learn, i imagine)

the term "weight limit" is a simplification, it's actually a mass limit. in other words when she can't lift something it's not because can't exert a strong enough force to counteract its weight, but because she can't manipulate this much matter at once. she wouldn't be all-powerful in space or when cooperating with ochako

speaking of the force that she can apply to objects, it can be pretty insane if she concentrates hard enough for a long enough time

she doesn't actually need to move her hands to use her quirk, but it helps her focus and visualize its effect better

as it's a major telekinetic ability, overusing her quirk gives Reiko headaches

(i'm making up so many rules and limitations because telekinesis is a BROKEN ability if you think about it enough lol)

Shiozaki

mix of her dad's ability to speed up plant growth and her mom's ability to manipulate her hair

since her vines are green, it's safe to assume they contain chlorophyl and therefore are able to photosynthetize. however, due to the way they're shaped, i doubt it's very efficient (bad surface area to volume ratio), so i suppose Ibara has to provide most of the nutrients herself. in other words i think she eats way more than the average person and drinks more water, too

failing to provide those will cause her ability to extend and move her vines to suffer, and in more extreme cases, they will just fall off. she can regrow them when that happens, but it takes time.

while theirs are obviously very different from ours, plants do have senses, and Ibara can use those plant senses of her vines as kind of an extension of her own

Kamakiri

another exact copy, of his mom's quirk this time. she actually used to be a pro hero, too (one day i might elaborate on this)

it does come with the innate desire to cut things, however thanks to his mom sharing the same quirk he received proper support so it never grew into a problem. on the other hand despite seeming scary, it's not that much to handle. he just satisfies that desire by cutting vegetables lol

by default his blades are extremely sharp, but if he focuses hard enough he can make them more blunt and less lethal

unrelated to the blades, but due to part-bug biology, he's much lighter than you'd expect someone of his posture to be.

and that's it for today~ i do have thoughts about the others' quirks but i felt like they weren't coherent enough to put here lol. maybe another day? also if anything here directly contradicts canon or if you just have other ideas, you are more than welcome to share your thoughts, i really like discussing quirks :]
