parents: if we take you drinking do you promise not to talk about anime science for one fucking night?
me: yeah ofc
me three strawberry daiquiris in: but it’s actually NOT impossible for shouto todoroki’s father to have O type blood while his father has AB as he’s a natural occurring chimera. there is one very famous case of a living chimera human with 61% type O blood and 39% type A blood. this is because chimeras can break genetic inheritance rules resulting in impossible heritable traits- which is probably why Shouto is perfectly split down the middle in regards to his generics in both quirk, hair, and possible other features unseen in the manga or anime like melanin production. it’s not unres-

All of you people talking about whether or not All Might died or not are missing the real most important part of this chapter.
Tumblr media
I went back and double checked, she didn't have that gear before. And you can see the guns growing out of her shoulder in that top panel. Do you know what this means?
Yaoyorozu has built constructs that only partially emerge from her body in order to refuel them with her Quirk. She is making ammunition directly into the weapons.
(Not only that but her signature bo staff has been upgraded into some kind of spear, and judging by the marking on the handle, it's also got some tech behind it as well.)
The armored plating on her legs seems damaged, so I don't know what it was like before, but the shield she has growing from her arm looks intact, with some kind of plating.
Yaoyorozu's gotten some upgrades! And possibly spent some time around Hatsume, considering the new gadgets she's using.

You know, thinking about it, the resolution of the Todoroki plotline might have me more convinced we’re getting a My Hero part 2 more than ever, because it…didn’t really resolve much. Dabi still wants to die. He still hates his family. No one in that family can talk to Touya to save their or his life. And I know some people have stopped caring over time; but corruption in hero society looks like it’ll still run rampant and we have 0 reason to think there won’t be more Endeavors and Dabis in the future.
Tumblr media
I mean all the 390 climax was, really, was Shoto using his ice in conjuncture with his family’s ice to overpower Dabi’s fire. And sure there was some symbolic meaning to the whole affair but…that’s really it, that’s the climax for the entire Todoroki plotline? No sympathizing with Touya, no convincing him to live, no Endeavor putting his family before heroics…just Shoto stopping a bomb we knew about for 5 whole chapters and leaving everything else as it was? (I guess there was also the world’s weakest-ass-apology if you want to count it.)
Look I know there’s a degree to which they’d have always had to talk about some things off screen, and they did say they were gonna talk. There’s already people supposing that 390 wasn’t the end, we’ll come back for a final-final resolution between the family. There’ll probably be something similar for Toga & Shigaraki. But some things is the key term; not everything. You can’t cut back to them for a few pages and address everything wrong with Touya in that time before moving on to the other two. I know people like to simplify the villains to make their saves seem easier & more guaranteed, but I think it’s fair to say Dabi’s a bit more complicated than that.
Tumblr media
And like, maybe it is just rushed writing; but the sheer degree to which all the bad blood is still there, coupled with Dabi’s new ice side of his quirk that we’ve done little to nothing with, just makes it seem like the Todoroki plot line is not close to done; which flies in the face a bit of this being the final arc. Hence why I’m back on my theory train as to how this is not the finale and there’ll be a My Hero continuation after the war.

Quirk Analysis: Frog (Asui Tsuyu)
The quirks from My Hero Academia have always been my favourite bit, so I'm gonna have some fun doing some Izuku style quirk breakdowns. The science here will be both real and theoretical. Feel free to use any of this in fics. My science background is basically exclusively biology so expect that to be the basis for any of my fake quirk science. Have a quirk you wanna see next? Just tell me!
First things first - her quirk counselor should be dragged out into the street and shot - her quirk isn't frog - it's chameleon.
Now, you may say "but she looks like a frog" and true! She does! But so do her parents - Tokoyami's bird mutations are unrelated to his quirk, as are Spinner's Lizard-like traits, and were inherited from one or both parents. I'm sure Asui's are too, given both her parents have frog/toad like traits (another thing - frogs and toads aren't distinct types of animal, they are the same animal with different names based typically on aesthetics but without any taxonomic background. but. I digress.) Her other frog-like traits (regurgitating her stomach, mild toxins, etc) are likely also inherited mutations.
The tongue of a frog is attached at the front of the mouth, giving in the ability to sort of flap forward and back. It's very soft, sticky and actually rather short, but that forward attachment lets it extend quickly and a decent distance. This is nothing like Asui's long, flexible and muscular tongue. It more closely resembles a chameleon tongue, sans the bony support it has on the end, though she does seem to have a similar tongue pad. I'd actually say its a pretty even mix between the musculature and dexterity of a human tongue.
Her camouflage ability - its true some frogs can change colour, but its typically from one standard colour to another, often during the breeding season. A fine control over colour change is seen in chameleons, though its a communication tool rather than a camouflage. She has the ability to camouflage her uniform too, so we are just going to have to assume that's due to a DNA infused fabric or some sort of inbuilt translucency, otherwise she has a mild light manipulation quirk in addition to everything else and I don't want to think about it.
The colour change mechanism in chameleons is really cool too! They have a few layers of cells in their skin called chromatophores, each layer is either pigmented or reflects a certain colour of light (they have names, but just know the colours are red, yellow, black and blue, like a standard printer (yes i know its cyan and magenta not blue and red but my point still stands). The chromatophores can expand, showing more of their colour, or shrink, showing less giving us a a shade through optical colour mixing!
Blue is the colour that's only reflected light, not a pigment, it's colour is purely structural. This is true in all animals! Any time you see a blue animal (or admittedly a green one) the blue on them is due to a structural quality of their skin/scales/feathers. This is not true for plants (and possibly invertebrates? i don't know much about them).
So, basically, a more accurate description of her quirk is 'chameleon-like traits with frog-like vestigial mutations'.
Some extra questions
can she breathe through her skin? If she can, she'd be able to stay underwater/holding her breath much longer than any standard human, though it wouldn't be sustainable (surface area to volume ratio - she doesn't have enough skin to get enough oxygen to fulfill her needs).
cold triggers an involuntary hibernation - the idea she can hibernate at all is just wild. It requires a lot of very specific adaptions to do so, which we'd have to assume her quirk gave her. This means her heart-rate and metabolic rate can slow dramatically without any ill-effects - chilling her would be an effective way to stop her from bleeding out, or a way to conserve energy during a famine/siege.
some frogs which hibernate in areas that reach below freezing have natural mechanisms which prevent damage to tissues when frozen - a natural antifreeze. she should be highly resistant to frostbite and death by hypothermia. you could also cryogenicly freeze her and then defrost her at a later date.
chameleons can control both eyes individually, giving them a great degree of vision while sacrificing depth perception - could tsuyu? given practise, any human can do it, so it's not impossible, but the increase in visual field would be limited and not particularly practical.

I wannna see Katsuki take one look in Izuku’s notebook that he burned, I bet he’d find a whole bunch of “Kacchan is going to be amazing” and quirk analysis on Katsuki, design ideas, and even strategies he could try out. And then all of a sudden he’d realize: “oh shit. This is good.” And then later in the sports festival he tries out one of Izuku’s strategies and Izuku is in the stands freaking out like “I KNEW IT WOULD BE AWESOME!! KACCHAN CAME UP WITH IT TOO. OF COURSE, HE’S AMAZING!!”
Meanwhile Katsuki just got it from him.

So what are your thoughts on the Gecko Quirk?
Tumblr media
"Gecko" is an odd power for me. It's such an afterthought in the whole series that it's hardly worth commenting on. It's bizarre with how little focus or substance it's given. I was kind of hoping it wouldn't be something interesting, but no, he's just a lizardman. A weak lizardman. Seriously, this may just be one of the weakest in the series, one of the few parts to make note of. I wouldn't even say it ties into his character that much. Outside of it being a weak power that has done more to hurt and demean Spinner, the most I could guess is that he's clinging to whatever he can for identity and validation.
Which is another thing that bugs me: why is it the only power that Spinner can stick to walls? Because the thing with geckos is that they actually have a lot more to offer than simply sticking to walls. They'd have long tails they can move, superior eyesight that can see in multiple directions, and a long, sticky tongue, to name a few. Which is nothing to say traits that'd be evolved with a Quirk, like a gecko's ability to heal. So either Spinner is not applying his Quirk as much as he should, he had some really bad luck with his power, or he is very attached to the whole  Walmart Stain look he has going on.

Hardening Analysis
To preface this, this will be my first proper analysis of a canon character, so be patient with me here. Also Kirishima Did Not cooperate on this one. 2 days and multiple hours of digging and research for Just this.
To start with a brief overview, Kirishima has a transformation quirk called Hardening that allows him to “harden” his body. This is usually indicated by his body becoming a series of flat edges, with incredible durability and strength added on. When pushed to the extreme in his “Unbreakable” form, sections of skin rise up and overlap each other as well as gain “cracks” all along his body resembling the metamorphic cleavage lines of some minerals. Another aspect that should be brought up is that his quirks limit is based on stamina drain. The “harder” he becomes over more area, the greater the drain on his stamina. Damage to these hardened areas also eats into his stamina pool, though it seems like by training his quirk he becomes more efficient and has a larger stamina pool to drain from (as evidenced by his growth between the Sports Festival and the Overhaul arc).
Now this all seems like it lines up very well. No inconsistencies, no strange happenings to pick at, just a simple consistent transformation quirk. Well Guess What! I Got his ass! There is More to Hardening and I have Found it!
First off there are some minor inconsistencies. For one Kirishima's Unbreakable form has raised skin all over his body, and yet this doesn’t cause him any damage and goes away after de-transforming. Also the lines that appear during hardening aren’t given any explanation, they’re just there and act to highlight how far hardening has spread. More damningly is the Overhaul arc though. In it Kirishima fights Rappa, who severely damages him, to this point that he’s missing a large section of arm. However that section doesn’t experience Any bleeding, whereas the wounds on his slightly hardened face do. And after the fight ends? Kirishima Just had a large section of arm torn off and doesn’t have access to Any healing quirks, and yet he Lives. He lives and doesn’t have Any physical therapy afterwards. No lasting damage, no bleeding out, Nothing.
So how? How does he do it? Well the only explanation I can think of that doesn’t require a bunch of coincidences is if “Hardening” comes with an extra healing aspect to it. But wait! How the hell does “Hardening” = Healing?! Well what if Kirishimas quirk Wasn’t Hardening. What if it was something incredibly similar but with far different mechanics? What if he had, for lack of a better term, “Crystallization”. More specifically what if Kirishima's quirk allowed for some measure of control over the atoms in his body. The ability to change them into a more crystalline pattern and Keep them there.
This would certainly explain some things. First off keeping everything together would cost energy, which his quirk processes his stamina to produce. And as crystalized sections are hit? As an outside force tries to Shatter him? His quirk would fight back, Forcing the atoms to stay put and unbroken. This kind of power would take energy, energy that would need to be taken by the quirk in the form of his stamina. If Kirishima had simple hardening this likely wouldn’t be the case, damage simply hurting him rather than eating away at his limit. His healing is in a similar situation. Regular Hardening wouldn’t grant any form of recovery, but if his quirk is forcing everything into predetermined shapes then inconsistencies would need to be patches, inconsistencies like wounds. Of course this would eat away at his stamina pool and we can’t risk the damage from outpacing his healing. If that were to happen then sections of Crystallization would need to be dropped or the whole body might fracture. How to combat this? Well if the body is forming crystal structures, it would be ridiculously easy to simply shave off sections if too much force to counter is applied. By shaving off sections of damaged tissue the underlying sections would be exposed, but could be quickly crystalized in specific areas to limit bleeding until de-transformation when the stamina pool can be safely drained for emergency healing. Of course this implies that Crystallization also redirects damage across crystalized sections to prevent internal damage, but considering the hits Kirishima takes throughout the series that’s not really up for debate (barring his Whole body crystalizing, but that would take stupid amounts of energy and the lack of blood from the arm wound during the Rappa fight indicates crystalized sections don’t operate as fully as they do when de-transformed).
Crystallization also explains some more minor inconsistencies, specifically his strength and overlapping skin in Unbreakable form. The strange skin formations could be Crystallization increasing the area's volume, but not having the required space. This could be handled by “lifting up” and overlapping over other sections of skin, creating the effect seen in Kirishima's new form. The strength aspect has ties back to the “reset-healing” aspect of Crystallization. By “resetting” his muscles they would spring back, causing the associated movement. This would cause a massive increase in speed and strength at the cost of potentially damaging the muscle. However, when combined with the healing portion of Crystallization this damage from hysterical strength would be healed up without trouble, and potentially even leave the muscle Stronger than before seeing as micro-tears in muscles cause an increase in their strength.
Now of course while this Seems like an upgrade from Hardening, and it certainly Is, there are some weaknesses Kirishima's quirk brings with it. The first one would be that Crystallization offers little protection against more elemental powers. Don’t get me wrong, he would certainly be better at taking a hit than a random passerby, but powers like electricity or mental quirks would still have some level of effect. This is actually supported in canon as the One(1) non-physical quirk Kirishima goes up against is one called Meatball, which immediately incapacitates him. Now this isn’t Entirely fair seeing as this was meant as a moment to make Bakugo shine and Meatball directly counters Crystallization (even more than it would Hardening), but it’s worth bringing up.
The second and equally important weakness is that the body was Not built for straight edges, and that has consequences. The first one is very hypothetical, seeing as I don’t believe Crystallization goes to far below the skin when possible, but if the lungs were to crystalize they would be Far less effective at delivering oxygen. Specifically the alveoli are a small circular portion of the lungs that’s responsible for oxygen distribution to the lungs, and that circular shape is to maximize how much is distributed. By crystallizing they become all sharp edges, reducing oxygen efficiency. At first this low oxygen would simply cause cells to produce energy without oxygen, known as anaerobic respiration, which produces lactic acid. Lactic acid sets off nerves like Crazy, which is that burning sensation you feel when exercising. As things intensify though Kirishima would begin to suffer from oxygen deprivation, which has a variety of symptoms but most notably includes wheezing, disorientation, and confusion. Very similar to his state after the Rappa fight, though that’s explained by the adrenaline crash and likely concussion.
Now the second major body weakness due to Crystallization I found was in the eyes. See, the eyes are circular for a reason, mess with that and light reflection gets wonky. More specifically, while flattened (as seen in the Rappa fight) the outermost sections of eye, known as the cornea, would reflect light further back instead of where it’s supposed to, leading to farsightedness. And the cornea isn’t the only part away from the iris, you also have what’s known as the anterior chamber. Flattening this chamber causes its own issues, but most notably its been found that prolonged flattening of this specific region causes damage to the organs in the eye. Now this Would be handled by Kirishima's healing aspect (further supporting its existence), it does mean that prolonged transformation risks worsening vision if healing can’t keep up.
Now every quirk comes with natural mutations to better handle it, but Kirishima is quite lacking in this department. The only major mutations I could think of is potentially thicker skin to give Crystallization more to work with, a larger mouth/lungs to more efficiently take in oxygen when fighting (especially if Crystallization affects the lungs), and some sharper teeth. Now the teeth could very easily be a vestigial mutation from a family member, but it could also be an expression of his Crystallization, with his teeth being permanently crystallized. This would result in them being far harder and sharper than average teeth of a similar shape, and potentially slowly train his quirk over time as it keeps up the mutation.
Some quick side notes that didn’t easily fit in elsewhere. Thanks to how hardness is measured, how much flakes off when scratched, Kirishima's quirk keeping everything together when possible means that he would have a Much higher hardness than his skin would naturally have, even while transformed (so “Hardening” in a sense) (he would also be highly resistant to fire for a similar reason, as heat wouldn’t be able to vibrate the atoms to damage or melt him as planned). He also displays some control over his hardening on the bus to USJ when he sharpens his fists rather than bulks them up, something I never caught him doing in battle when it might harm someone. It’s also worth pointing out that higher Crystallization levels might be an indicator to the quirk to up the healing in that area, rather than being an automatic process. This is most supported by the fact that while the arms were heavily crystallized and suffered no bleeding, his face was only lightly crystallized and Did bleed.

So Suneater mainly fights with squids and crabs and other seafood because Japanese food has a lot of seafood in it because they are on an island right? Now imagine if he was born in America how would that change his fighting style? I’m guessing bull horns but what are your ideas?
What about other countries how would their natural diet affect his fighting style?
Just some Food (lol) for thought

I’m having. A lot of thoughts about fuyumi lately
So you’re suffering with me
So Touya hair turned from red to white the more he used his quirk
Do you think that’s what the little red streaks in her hair are from?
The few times she used her quirk for something, she can count each of those memories on her red stripes
That’s what I think

I know nobody is gonna really care or talk about this with me but I’ve been thinking about this and now y’all have to suffer with me :)
In My Hero Academia, what do they do to the people with extremely deadly quirks?
Like say there’s this kid who just gets their quirk. They’re like 6 rn so they’ve done literally nothing wrong. They find out that their quirk can unalive people unintentionally.
WHAT DO THEY DO WITH PEOPLE LIKE THAT
Like do they just isolate the kid so they don’t unalive anyone else on accident? Do they just get rid of the kid??? Do they try to get the quirk under control if it CAN be controlled but then they risk more lives???
Like imagine having a quirk called D3ath Stare or something like that! Where it’s super easy to accidentally unalive someone or maybe it’s something they can’t turn off!
What happens to those people?! The fact that we haven’t seen anyone like that yet is really interesting to me because we all know there’s a super high chance that there’s someone with a quirk like that!

Okay, so related to that one post abt somebody with plant powers not really being able to control ibara, how DO you think she sees the world?? Like to be honest i live your interpretation of her quirk and could read a whole book on it. You said it was kinda translated right? so how would she expreince her senses then??
Haha, thats a really good question! Ive actually been reading a book on plant perception lately (What A Plant Knows, by Daniel Chamovitz) so while i cant say i definitely know everything, its helped put things into perspective. also for the sake of Not Being Buzzkills obviously horikoshi didnt think abt this its just hc im using canon to supplement and draw conclusions dont be silly
also um. im putting this under a cut because it really is a book's worth of meta. i got really excited.
But i think, from how we see Ibara, a large part of it is going to be filtered through religious experiences+delusions. It already seems like how she talks and understands thing is subconsciously put through this filter (i dont think shes calling shishida "apocalypse beast" out of spite or to be inflammatory-- there is religious theory that the beast of gevaudan may have been god-sent, albeit this theory is rare and far from widely accepted. Ibara doesnt seem to follow any specific doctrine, though, and i really think parts of it are just kinda her brain drawing connections in line with her deeply personal beliefs as opposed to dogma. To her it may just be that she believes theyre saying the same thing in essence, while he does not)
But on the topic of sensory experiences specifically, I would also say that Ibara is experiencing exponentially higher levels of sensory input than most people, so i cant blame her for being a space cadet. And while the fainting is an anime-only gag presumably to show her delicate sensibilities or whatever i personally am choosing to interpret it as an incredibly reasonable consequence of her brain hitting the limit. Like cut the cameras im OUT!!! It's documented frequently in the history of religious ecstasy and other spiritual experiences, so adding an assload of input i can imagine only heightens your chance.
And so onto your question about how that manifests-- its hard to say! But i have a few ideas.
Firstly, i think we should address what the plant is perceiving, and how. In a base function, we can say that they respond to stimuli in certain forms (light, sound, smell, balance, touch, etc) which loosely correlates with our own senses. They differ in the organs used, though, but Ibara having a centralized animal brain both simplifies and complicates it.
Plants don't "see" pictures-- they have sensory cells dedicated to seeing both light and different wavelengths of light (which helps control their circadian cycle and even flowing schedule! Even a small disruption of flashing a certain color light during the night can allow farmers to delay or change when certain plants flower), but these arent rods and cones connected to an optical nerve connected to a brain. But at the same time, they... ARE connected to a brain.
I think for Ibara, plant sight is like a murky, back-of the mind addition to her normal range of vision. It's not a picture the same way her Eyes work, but she knows intuitively theres light, shadow, and colors around her, and can focus in on it a little more if she tries. Details and motion that doesn't block light wouldnt be part of it-- the plant can only see what blocks light covering it or reflects light onto it. Ever-periphery flashes of shadowy shapes and colors. (and conversely: i think the prayer pose, with eyes closed and hands clasped makes it easier to focus on the information filtering through)
sound is also different-- while the studies about plant growth and music are bunk, plants do react to sound. the mechanics of it are still heavily under-explored, but we know they do, just so long as its sound that may be relevant to a plant, like running water or insects chewing. I don't think Ibara could do what Hawks does-- where he can focus in on sounds through his wings and hear conversations. The vines aren't a dedicated sensory organ, they just communicate signals back that are of relevance. She may KNOW there's sound somewhere, but it's background noise until it's something that triggers a response. The question is really what would be deemed important enough to do so.
See, the thing with plants is that they don't have emotions, or even a centralized brain, as we've established. Animals can and do. humans especially. Things deemed important by a person can be important for a variety of reasons, beyond just survival. While Ibara uses the vines as an extension of her limbs, it doesn't change the built in systems of stimuli response the plant has, but the plant isn't a brain in the sense that it will decide anything. So the question of What Ibara Hears from the plant is an interesting one. Personally, I don't think she hears the sounds "as is". Ibara doesn't HEAR insects chewing, because the cells are communicating a stimulus and response, so it would be an interpretation of the response. Sort of a plato's cave issue-- I think ibara may say she "hears omens of danger" or "tidings of great joy", but it's not like she's being told a Coherent Thought By The Vines. it's sound of water = good = we are safe and can find safety + an avidly catholic teenager = the angels bring tidings of joy. it's thing she "hears" but doesnt hear because its never actually touching her own aural organs or nerves. She may not be able to pinpoint what the sound itself is, just what it evokes or what her brain fills the gap in as, like talking.
Taste and smell are both something plants do, but defined slightly differently, as we associate these things with specific nerves in the human body that plants Dont Have. to define it the way my book does, we're going to say "taste is the reception of chemical signals through touch" and "smell is the reception of chemical signals dispersed through the air". and plants do taste, and taste one another-- many parasitic plants show preference for certain species, like the dodder vine. other vines, especially those that climb, will avoid climbing their own species because they know that the support is unstable. this is something they figure out by the chemicals they release onto their surface. This is something that would really be tightened up by ibara having an actual real world plant on her head but trust me trying to find anything that matches is a mess. more on that in a bit. but we know, in theory, she can "taste" other plants, and maybe even other type of similar compounds through these vines, which i think would then also manifest in at least a vague idea of a taste in her mouth-- once again, platos cave of sensation, although honestly its probably a bit more in line with what the actual thing would taste like. (tomatoes, for example). this taste may also correlate with a signal that associates emotionally, but ill touch on that in the pain part of this.
Smell is similar- once again, just detected through the air instead of touch. (The smell of cut grass? An airborne danger signal. Ibara probably can't stand being around freshly-cut lawns, it must feel like a giant panic attack. How this would manifest? Not sure! The smell of blood? As a sound instead? It's hard to say what could compare to the scope of fear that kind of flood would cause). I won't go into depth since it's the same as above, but I would also like to add carbon dioxide as a mention. Plants can detect levels of CO2 (and it can decide how they photosynthesize!) in the air, and I think because for Ibara, photosynthesis has to be accelerated (due to the faster growth and usage of energy being more akin to that of an animal instead of a plant) and she and the plant share an exchange of signals and nutrients.
I'm going to diverge briefly into the realm of digestion and nutrition. Firstly because I love it. Secondly because it will circle back to our carbon dioxide talk.
Ibara's vines are, as we see, leafless. This is quite relevant. Leaves, as most people know, are responsible for the majority of photosynthesis. While chlorophyll in any parts of the plant can photosynthesize, leaves are by far the most effective way thanks to the broad surface area and certain specializations. Leafless plants (especially in the case of vines) tend to be parasitic. Plants that evolve photosynthetically-inefficient leaves tend to be carnivorous, which I would like to explore a little.
A plant is defined as carnivorous if, typically, it shows a form majorly inclined towards having prey-trapping mechanisms, and receives a substantial amount of nutrition from doing so. They tend to grow in areas that have high sunlight and water levels, but with incredibly nutritionally deficient soil. Nutrients like nitrogen, phosphorous, and proteins, which are found in meat (bugs included)
Now, Ibara's vines don't have visible roots, so I think it's safe to assume the root system is within her body, and goes deep below the surface. Water, nutrients, and neurological signals all need to be shared; and so I think her entire body is connected to this root system. Ergo, all the nutrition the plant gets that isn't photosynthesized comes from what Ibara digests-- which is also why I don't personally subscribe to the vegan or vegetarian Ibara headcanon-- because nitrogen and phosphorous are INTEGRAL to stem growth, and baby, she's all stem. In fact, I think she probably loves meat-- second only to bread, which provides long-term energy in the form of complex sugars. I personally think Ibara would dislike sweets in the traditional sense of candy and desserts outside of winter-induced cravings from a drop in photosynthesis, but that would be because the sugars her vines produce for her already maintain a decent level of homeostasis, so it would cause her blood sugar to spike and make her feel ill. Conversely, bread breaks down and is stored much more long term, so it would both benefit her and the plant, which is inefficient at photosynthesis compared to a plant of the same size with leaves, and would need a boost given how much energy it uses to grow, detach, and move.
I know this girl can put away a MEALLLL after training. Yaomomo style.
I think you could argue Ibara (and her quirk) qualifies as a carnivorous plant. Her vines lack leaves and instead have developed extensive thorns (which can be a type of modified stem-- its complicated and varies plant to plant), and we never see them branch off of each other, so they may not even be capable of developing stems. She also doesn't appear to have any flowering mechanism (nor does she need one!), although I will say I'm a sucker for the idea of Ibara having psuedo-blossoms that aren't functional flowers, but rather an indicator of health. Either way, the heavy focus on the vines for strength, complex movement, and grasping through pointed extrusions makes me think you could convincingly argue that they are the "trapping mechanism", which is a requirement for carnivorous plants.
So, once again, we've established that there's a complex nutrient exchange both from Ibara to the vines, but from the vines to Ibara. And because of this, I think there's an added level of complexity to her digestive system-- specifically regarding the stomach's direct connection to the brain. Just like her own nutritional needs can trigger certain responses like in any person, but the plant probably has the same access to these hormone signals. Things like craving sugar and being irritable in winter because of the inability to produce her own as much, but also conversely, I think the plant can trigger a digestive response to prepare for the influx of sugar being photosynthesized. A "heads up, we're about to start sending this your way" to help maintain proper levels.
So, back to carbon dioxide finally. When plants detect higher carbon dioxide levels in the air, they may photosynthesize more. This may result, in my opinion, to "phantom smells" and a trigger to the digestive system, resembling how our own mouth waters when we smell food. Whether it's just an ambiguous food smell or one specifically (maybe bread?) to Ibara I'm not sure, but what I'm saying is that if Bakugou's explosions over the course of an hour can produce about the same amount of carbon dioxide as an entire person throughout one day, she probably thinks he smells fucking delicious and for no reason why. It's funny to me.
Ok! On to touch. I think it's obvious that Ibara's vines react to touch and that's transmitted to her, given how she knows that she's found someone and is pulling them out in JTA. Plants definitely can feel touch, and respond, but I'd like to note that plants can't feel pain. They don't have the ability to feel pain. They can react to adverse touch, certainly-- for example, grass releasing their smell when cut, but they don't feel pain. It's solely for survival, and feeling pain isn't really important for a relatively stationary being. Nor do they really have the factor of emotional association with pain that typically is bundled together. But in the case of Ibara; who, once again, has the burden of the complex mammalian brain... maybe she does feel pain, even if it's not "real"! It likely has to do with whether she has the expectation of and emotional association of fear/pain/etc, so simply cutting away the vines aren't likely to make her hurt. But I don't think phantom pain is out of the question, especially for someone already as high-strung as Ibara and who has so many wires crossing at so many times because of the nuance of the signals transmitted from cell to cell.
And related to touch... a fascinating and storied study in plants includes gravitropism and proprioception, or-- balance and how they know what's up and what's down! People have incredibly complex proprioception systems (most people know about the inner ear, but it goes far deeper than that!), and plants, too, make use of this ability. In fact, it's integral for plant growth.
Plants have two main mechanisms for gravity sensing. The root caps, and then in the stems, the endodermis (which is also responsible for osmosis in cells, sorta) both have genes that develop statoliths, similar to the otoliths we have in the inner ear. These statoliths tell the plant which way gravity is pulling. The root caps make roots grow down, the endodermis makes the shoots grow up.
I think for Ibara, her vines have become an extension of her own balance and ability to know where she is in space. Losing all of them suddenly would result in something similar to a damaged ACL-- having to readjust and being wobbly for a while. Not only that, but I think quirks that impact someone's sense of balance would seriously waste Ibara. While Ibara does move her vines in more ways than up and down, the ability to tell what's what still relies on the individual cells in the stems and roots. While Ibara would still be able to produce the growth hormone and self-amputating mechanisms that detach her vines (i have to look more into this, honestly-- autotomy has only been recorded in one type of plant, and even with abscission ibara's vines dont follow typical patterns. smh my head.), there would be little if any control over the movement, especially if the balance reduction hits the endodermis in more ways than one, because that would impair the hydrolic movement that causes movement in plants.... Either way, Ibara's quirk would be rendered functionally useless. Deidoro Sakaki has this one. And in my opinion, with Uraraka's quirk, they would grow, but wouldn't show proper gravitropic bending, and so may also be impaired in their ability to perform actions.
And I think a complete removal of Ibara's vines would honestly feel like... overwhelmingly suffocating? Imagine having so much of the senses you're used to having cut off, it's probably incredibly jarring and upsetting. I don't think she would prefer it to the every day life she lives, because it seems like she's generally not that impeded by her own world view and strict standards, even if others oppose it (OCD queen lets go #1).
So...as a TLDR; I think Ibara experiences normal human sensory input, she just has another layer that bleeds into it. While I often refer to the plant separately in the above, that's solely for clarity of biological mechanic explanations-- they're one and the same, the same way we started reproducing mitochondria despite their likely beginning as a different organism. She may see things that aren't there (like in the case of warning signals from other plants, or in her mental translation of all sorts of things), "hear" things in her mind, smell or taste or even feel pain... while the mechanics aren't the "real" ones we associate with the senses in question, she's still reacting to stimuli she is receiving, and I think she's learned to adapt to it. It's hard to explain, because it almost has a sort of eldritch feel... but really, Ibara is Ibara, she's a bit stubborn and translates everything into her world view, and so that determinative personality probably helps streamline the constant influx of information. Angels, music, emotions, memories-- those are things she assigns to the experiences, but they are no less validated by the biological machinations behind them. Human survival also relies on our ability to feel and the more complex machinations of the brain, the social advantages of more refined expressions and speech, and Ibara's just as human as her classmates, and her quirk ultimately is another part of that, even if we know the individual cells of the plant are without that same neurological function.

aaaaa im REALLY excited for this new quirk- by itself transmission was really powerful. deku is using it to power his body right now but the original user used gun gauntlets to fire projectiles at high speeds. i can't imagine how unstoppable Second would have been on the battlefield, no wonder why AFO is scared of him
by themselves these quirks aren't powerful and kinda utility based but combined together along with the OFA stockpile, they create powerful combinations with devastating power. like Transmission + Float + Fa Jin will allow Deku to move at terrifying speeds, storing energy and then just pummeling away at enemies without allowing them to follow your movements. And if that Fa Jin energy is transmitted to Black Whip, the Black whip can too hit like train from medium distance with maximum striking power. this combination is really impressive

Do you think Tsuyu could produce poison?
Apparently in nature the frogs poison comes from their diet so eating the right things maybe she could?
She technically already does. She can produce a paralytic mucus. If other frogs have more potent poisons I see no reason why she wouldn't be able to

Hey you ever think about how, aside from his own, the very first and very last quirk AFO ever used:
Tumblr media
Was Spearlike Bones; the quirk of his & Yoichi's mother?
Tumblr media
Because this revelation has given me some weird feelings and I thought some of you might enjoy them too.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
On a less emotional note: between the above and being the first known quirk, this thing is quite steeped in significance, isn't it?
Ironic when it was introduced as just another in AFO's collection, first mentioned in the paragraph of his ultimate quirk combo in Kamino like it was nothing special. Wonder if he ever really knew what he had? Did he ever know this was the oldest known quirk? More importantly, did he ever know it was his mother's?
Knowing him, probably not.

ONCE AGAIN WITH THE ADVANCED PHYSICS COURSE AND I AM HAVING THOUGHTS ON URARAKA'S QUIRK THIS TIME
i think a lot of people how is it called are asleep on her quirk? They don't give it the credit that it's due is what I'm trying to say, and when you understand the physics behind it you start to understand why she's just so fucking OP
We know that Force Gravity while on earth is Fg = mg (that's saying that Force Gravity equals the mass of the object times the gravitational constant/ acceleration due to gravity of earth, which we generalize to be about 9.8m/s^2, even though it actually varies quite a bit based on where you are on the planet and the density of the materials below the surface of the planet at different places).
If you write Force Gravity more generically (aka not just for THIS planet, but for ANY planet) Fg = Gm1m2/r^2, where G is the universal gravitational constant, m1 is the mass of the planet, and m2 is the mass of the object being attracted, and then r is the distance from the center of the planet to the center of the object aka the Radius (this is most commonly used for objects in orbit, but it applies anyways)
That being said, I think there are a couple of ways Uraraka's quirk could function:
She's locally affecting the gravitational constant (g) of wherever she is on earth but only by touching something-- or perhaps she exerts her OWN gravitational constant on the object by touching it that then works to cancel out the normal g from the earth? But this is unlikely because of the number of things it means she would need to change or affect... Basically if Fg = Gm1m2/r^2 and G is the universal gravitational constant (extremely small-- it's 6.67 x 10^-11 m^3/kg*s^2), then in order to make this equal to 9.8 she would need to be making either her own mass (m1) or the mass of the object (m2) absolutely MASSIVE, or she'd have to be manipulating the distance between them to be incredibly, dare I say, impossibly, small (since the smaller r is the bigger Fg will be). But none of these options seem very likely given what we know from the manga & anime from when she uses her quirk
She's making it so that the distance between the object she touches and the earth's center is somehow infinite. This is because, if r is infinity, then no matter the number in the numerator, if it's divided by infinity it'll be physically 0 (although technically undefined, if you want to get calculus-y about it). For a more physics explanation of why this works, it's basically because of the direction of integration for the potential energy of an object in orbit due to the gravitational force of another object -> we integrate from infinity to r (r being the distance from the center of the object exerting the gravitational force to the object being attracted to it), and say that Ug (potential energy due to gravity) is 0 at infinity-- another, simpler way to think about this is to just go ahh yes, if the distance between the object and the mass whose gravity is affecting the object approaches infinity, then Fg will go to zero because this is how numbers work. However, this would have to make Uraraka's quirk a sort of 'opening a personal wormhole' type deal, in order for it to make an object be physically infinite distance away while still appearing to be here (wherever 'here' happens to be), which also doesn't really fit how we've heard/ seen her quirk described/ function
She's negating the mass of earth, the object, or both, but-- CRUCIALLY-- only for the object-earth system that she's touching in that moment. This is because if you are dividing 0 by anything, it is almost always zero, so Fg = G *0/ r^2 = 0 and means there's suddenly no gravitational force acting on the object she's touching. I think it makes the most sense that she'd be negating the mass of the object, and not the planet, because it's been said that the bigger the object she uses her quirk on, the more she struggles, indicating a correlation between mass and quirk ability. Basically if she were trying to negate earth's mass she'd just be sick for the rest of her life is what I'm saying, and, since she's not, she's probably negating the object's mass.
Now #3 is the one that I personally think is most likely, but EVEN THEN you have to understand that uraraka is fucking with one of the four fundamental forces of our world (that's gravity, electromagnetism, weak nuclear, and strong nuclear).
If she is somehow negating the mass of the object for a specific object-earth system, then this means she is also negating its interactions with all the other masses around it (EVERYTHING with mass-- even teeny tiny little singular particles-- exerts a gravitational force on EVERYTHING with mass around them. It's just that most of these things are smaller than, you know, the whole damn planet, so you never even notice them). If everything with mass exerts a gravitational force, but suddenly Uraraka can make that gravitational force disappear... well frankly I don't know where that leaves us.
She can make mass 'disappear' (at least, in the physical sense) but does that mean she's actually "unexisted" the object, for lack of a better word? What I mean is, if an object has no mass & therefore no interactions with the other objects around it in the world, then does it exist? Certainly not to the other objects around it, it doesn't-- they are no longer being affected by its (relatively small, but still present) gravitational force, and it is also no longer affecting them with its own (relatively small, but still present) gravitational force. Like I mean obviously it's still there visually, but HOW? It's made out of particles, but those particles have no mass anymore, and our basic understanding of these building blocks of the universe, of matter, is literally "that which takes up space and has mass." So is this some sort of 'opposite of matter' now? Would we call it a 'half matter,' since it only fulfills half of matter's definition (still has space, but no longer has mass)?
Since we're getting philosophical, what does it mean that Uraraka can essentially partially "un-exist" matter? Matter itself is supposed to be one of those things that cannot be created or destroyed, only changed in form (conservation of matter). So does this make Uraraka some sort of 'Unmoved Mover' figure for the BNHA universe ????????
Anyways, TLDR:
I think Uraraka is as close to magic (or divinity??!)!? as the MHA universe gets and that scares the shit out of me

Katsuki Quirk Theory
So. I wanted to bring up a quirk theory I heard suggested once, and have THOROUGHLY researched. It comes up in a lot of my fics and I think it’s so important in explaining Katsuki. MENTIONED UA TRAITOR SPOILER DON’T READ IF YOU DON’T WANT TO KNOW! 
Nitroglycerin is, in real life, prescribed as a medication. It relaxes blood vessels and can alter heart rate - usually slowing it down. This is a controlled, medicated prescription because in LARGE amounts… well…it’s slowing down the heart - that can be pretty freaking bad. We know that Katsuki - at least in his hands - produces nitroglycerin. He gets this from his parents combined quirks - his father’s acid and his mother’s glycerin. I am not as certain of glycerin/glycerol effects, but one or two articles I sifted through did say that in SOME cases heart rate can be slowed down as well - others sped up.
Where I’m going with this is, typically, people born with quirks have some sort of natural defense against them. It’s why OFA causes such a strain on the user’s body, especially Izuku, and why Aoyama gets sick using his quirk - they weren’t theirs to begin with. Now, I know not EVERY quirk has built up defenses, and every quirk has a drawback (Aizawa’s dry eyes, Uraraka’s puking, Iida’s engine stall - etc etc). But, overall, I think most quirks come with a natural defense. There’s always been debate over whether or not Katsuki will or won’t lose his hearing - maybe already has since he’s so loud. I PERSONALLY think his body probably gave him sturdier ears to prevent that, but that’s just me. And I also think that Katsuki’s body came up with a way to defend against the possibility of Nitroglycerin poisoning - only it might be the biggest drawback of all. 
Anxiety and Anger can MASSIVELY boost heart-rate. 
Who is angry all the time? Katsuki AND Mitsuki. 
Is it possible that Katsuki’s anger/anxiety issues stem from his body trying to keep his heart rate up? Is it possible that the nitroglycerin and glycerin require their bodies to combat slower heart rates? (Maybe for Mitsuki her heart is doing the opposite of slowing and just constantly going fast - keeping her in a mental state that’s higher?) 
We all know that, while, sure, Katsuki was always a bit of a shit - he and Izuku WERE friends before he got his quirk. We put so much of the blame on his personality - on the ego he got from his quirk being epic. And I don’t dispute that as being part of it. But is it possible his quirk genuinely screwed with his brain chemistry? 
Is it possible that his tendency to ‘explode’ partially gets worse when his body is trying to dispel large amounts? That his anger and anxiety decrease after he explodes shit, not just because he let something out emotionally…but physically? Possible that he is calmer after because his heart rate can slow but not dangerously so because he isn’t full of nitroglycerin? 
I doubt that a doctor or anyone would ever look into this as a possibility because there would probably be an assumption that it was all ‘bad attitude’ or ‘personality’ maybe even simple upbringing - what with Mitsuki’s anger issues and all. 
But think about how angry Katsuki gets - some of the pivotal moments in his and Izuku’s lives. If my theory is correct, he already would have a baseline of high anger and I truly think anxiety. Just because his body is trying to keep his heart steady. (the more the nitroglycerin pulls it down, the higher his anger/anxiety would work to pull it up). But add on an external moment of anxiety or anger? It’s going to be for all LITERAL intents and purposes like a ticking time bomb. Katsuki falls in the river? He’s scared? His anxiety is going to be even higher. Someone comes to help him? BOOM. 
He gets extreme anxiety while the sludge villain is suffocating him? Rabid ‘monster’ BOOM. Izuku saves him? He’s vulnerable/anxious and now even more angry? BIGGER BOOM.
He gets muzzled after an anger episode? Triggering his anxiety over suffocation? RABID BEAST ONCE MORE MID PANIC ATTACK. He thinks he’s responsible for the fall of the greatest superhero? That the world is falling apart and it’s his fault? Yeah…that normal anxiety? Now skyrocketing. His heart rate is going crazy, his nitroglycerin builds up - both sides are attacking one another and he needs to boom the hell out of someone he knows can take it - Izuku. Baboom! 
Wakes up in a hospital where he hasn’t been able to dispel any nitroglycerin? Learns Izuku is still unconscious? (the love of his life) BOOM! Katsuki’s body chemistry is literally ALWAYS fighting against itself. So when he starts to realize he’s an ASSHOLE and wants to change…. He is fighting an uphill battle in a nitroglycerin hurricane because his body is pushing him down in this war against its own chemistry. And that, Ladies, Gents and Those of you in between, is why his character progression is that much more meaningful. Because he still begins to overcome himself - even with all of that happening. And THAT is why I love him. 
~KatsuKimchi~
