Deku's mom has the ability to attract objects, while Deku's father can breath fire. Deku's mom+ Deku's dad= ability to attract hot things. Garaki stole it to build his own harem.
I mean, Dr. Ujiko finding Quirks to steal through his appointments is basically confirmed since one of Deku and Bakugou's childhood friends was used in one of the Nomu. It's safe to assume he is the go-to Quirk Doctor in the area and their friend saw him at some point as well.
I have a different theory on it. I think he didn't have one at all still. Just like OFA effects the body so it is better on a quirkless body, I think AFO does too. So Ujiko, who is creating Nomu as bodies that can hold multiple quirks, was searching for children without quirks to become a new body for AFO. Deku didn't have it stolen, Deku was getting sized up to be a new container.
That's actually a good theory because izuku can't have decay as his quirk because none of his parents have a decay type quirk and no were near to being the same
@@IDK-km7vd I hope you didn't forget that quirk can mutate just like in Eri's case non of her parent have the quirk that resembles or close to rewinds at all yet her quirk came out as the one we seen so it also make sense that deku COULD'VE been the original owner of "decay" 😅
4 problems here. 1. Deku is younger than Shigaraki, so either there's time travel involved or it didn't happen. 2. Deku's mom had limited telekinesis and his dad could breathe fire. Since quirks have been shown to be passed down and combine in some fashion, I highly doubt those two combined into the ability to _disintegrate things on touch._ The only exception being a quirk mutation, but those are very rare as far as I'm aware. 3. This theory would also imply that the doc found out about, identified, and orchestrated a way to steal the quirk before it even *_manifested_* considering that there was *_zero_* mention of Deku disintegrating things as a child. It's a 5-point contact quirk. No way that Deku wouldn't have met the activation requirements at *_least_* once before the doc could take it. 4. It conflicts with lore. According to the anime, the entire reason that Deku manifested the multiple quirks of OFA is *_because_* he was quirkless. You have to be quirkless to wield the full power of OFA. I believe they even specified quirkless and not just having a quirk stolen. Edit: Revised point 2 since I have been informed of a few things I missed. I also added another point that I thought of and made it easier to read.
Actually quirks can skip generations kind of, as you can get your parents parents quirk and their parents parents but you get the idea, and I do agree there are reason to this theory is just that
@@ordinaryone2833 It's not the same. The reason he's able to manifest all 6 or so quirks of OFA is because he's never had a quirk before _at all._ That's the explanation they gave in season 6 anyhow.
@@wickeli The in universe explanation is that the quirk wasn't ready or Deku had some special talent for it. Out of universe however, we have no idea other than it's probably just because the writer's thought it was cool. Why they didn't just make All Might have a quirk or something we may never know. So long story short: that is how it works, but why it worked for one and not the other is a mystery.
More likely than this theory is that the thematic reason for Garaki being the doctor to tell Deku he was quirkless was that Deku narrowly avoided becoming someone who they would kidnap to turn into a Nomu. Because they confirmed that the one nomu who had wings during the stain arc was actually the kid with wings from Deku and Kacchan's first flashback scene in season 1. It's possible that most of the kids in that area all went to the hospital Garaki worked at and were therefore all seen by him as their quirk related doctor. Not to mention that this theory completely ignores the reason Garaki says Deku is probably quirkless which is that he has that pinky toe joint. So unless Garaki, unbeknownst to Deku or his mom, gave him an extra pinky toe joint then it's probably bunk.
@@Randus1058But wouldn't the OFA vestiges have known somehow that Deku had a quirk. They showed him Shirgaraki's past. Why is it that they don't know that he had a quirk.
@@Randus1058Because it would be suspicious if a kid with an explosion quirk and assuming he uses it daily suddenly lose his quirk after the hospital visit. Plus, I don't think it is necessary to send him to the hospital since quirk is a natural thing that happens in daily life unless the quirk itself hurt the user like Dabi's quirk.
problem is we see midoriya's back story and shigarakis, shigaraki is an adult, and midoriya's a teen. meaning its literally impossible when midoriya wasnt even alive when shigaraki's quirk manifested
@@harman7978 i think it’s like: if people are born with their quirks but they’re dormant until they’re about 4-5 then it should be *possible* for AFO to steal a quirk from a kid who hasn’t developed their quirk yet. I don’t think it’s very likely, but it is a possibility.
@@mimikyu__- I'm pretty sure it's possible to steal quirks from babies who haven't manifested it yet. But then the question, how does AFO knew what those unmanifested quirks are? Like, Izuku's parents have fire breathing and weak telekinetic quirk and a child's quirk is usually the same/similar to their parents (Jirou Kyoka for example) or a combination of their parent's (Bakugo Katsuki). So logically, Izuku's quirk should be something related to fire or telekinetic. Not something as wild as decay.
I actually once considered this possibility, but Deku was almost guaranteed quirkless when the analysis showed that he has two joints in his pinky toe -- whereas people who are born with Quirks only have one joint. Then again, it is also possible that the Doctor lied about the checkup results.
I love how nobody stops to think that maybe the doctor used someone else's x-ray... he was literally helping afo kidnap and steal people's quirks, but the x-ray is the Smoking Gun that he would have never faked?
or it just fact, also the pinky thing can easily be test at home, you can grab your foot and check the joints just like your hand joint only pinky toe tip joint might just be a nub. it not rocket Science it basic biology, also it actualy a Scientific theory that humans will lose the pinky joint just like the vestigial tail bone but not proven yet.
So here’s why I think he didn’t have a quirk. His father had a fire breathing quirk, and most fire users have some sort of resistance to burning some immune some taking a lot of fire to burn. So if his dads quirk was fire breathing and Deku inherited the flame part of it then shouldn’t Deku also be mostly immune to burns? But as we see in the very beginning of UA when Deku fights Bakugo, Deku sustains some pretty severe burns so likely he was just born quirkless.
Fire breathing would most likely give resistance to mouth burns and that’s if he got any from his father. Dabi’s issues with his fire is also a problem so there is a chance there is no resistance. Bakugos quirk is explosions which is different than fire as well
@@YukiA816 Yes but his mothers quirk was ice, and he got the immunity to cold. And if a person with fire breathing for a quirk had only the inside of the mouth immune the lips and a lot of the face would get burned badly
He could also be just resistant and not immune. After all, explosions at even a small scale should leave at least some small scars, but Deku doesn't have any scars from the explosions over the years
@@barretthegamingbear708 I don’t think that’s the case either, because deku has sustained a lot of damage of many types over the years at UA, but still has no scars from those. His current scars are literally just from ofa. So either he has a weird healing where he has no scars form except from very specific things, or it’s just illustration. We will probably know the answer when the final chapters are released
Decay doesn’t make sense unless Izuku was like Eri and had a Mutated Quirk Factor or if AFO is really his Father (I don’t subscribe to that theory). If Izuku’s Dad really is just Hisashi Midoriya with a Fire Breathing Quirk then a Fire Based or Telekinetically Based Quirk makes more sense…
Well if you mixed flame control (fire breathing) and small scale telekinesis, you could have a sort of "decay", fire burning everything to ashes. That along with the quirk singularity could yield decay. I don't subscribe to this theory but it was always my thought if it was the case that deku did have a quirk.
Well the way fire works in the most simplified sense is it accelerates entropy by speeding up the molecules of whatever is on fire. So fire control and telekinesis would actually make sense to be the parents of a mutated decay quirk user. The more I think about it the crazier this theory gets. Also in regards to shigaraki being older than deku, there is the possibility that Dekus father was working with AFO to get with Dekus mom because they knew based on research that combination of genetics could develop a strong quirk, Dekus father develops feelings for his false family and tries to go up against AFO and gets bodied hard. Ain’t no way if his dads just a bum he hasn’t seen deku in the papers like bum dads in real life coming back into their kids lives when they win the lottery or become successful, he is capital D dead or a villain. My point is Deku was born around the time Shigaraki developed his quirk under mysterious circumstances, and the doctor could’ve just made something up to throw them off the trail completely.
Ah yes, the doctor after stealing a quirk he didn't even know Went *BACK* in time to give it to shigaraki and the quirk manifested at the same age Deku's was stolen
Unless the doctor has a Uber powerful quirk he doesn’t disclose all its potential where he can steal quirks, not able to manifest them into physical ones he can use but his quirk permits him to travel time even say just astral like with the ability of gifting quirks he has absconded. This is just a theory and theory takes imagination, intelligence and creativity particularly in a story about based upon beings with a multitude of abilities, which for an anime fan you seem to surprisingly lack and want your stories fed to you in absolute’s
@@josephhorrigan4078 also yes, I want my story in absolutes because I want a story that make sense & leave nothing to the imagination If I have to decide what is and what isn't then I might as well add my name next to the mangaka since I'm creating the story as well Your comment isn't adding up to much tbh
No.1 The doctor works for all for one. No.2 The dude that sent tenko home was wearing a tuxedo and a fedora later we can conclude that that man was all for one because later we can see afo who was wearing a tuxedo and a fedora take dabi in. The appearance of the mysterious man looked exactly like afo. The doctors quirk has a quirk that can live twice the amount as a normal person can live. We can also involve the theory that afo is dekus dad meaning afo stole his quirk when he was very little then left the family then gave the quirk to shigaraki
It would honestly be so tragic if deku developed decay I don’t think my heart could take someone as precious as mama Midoryia dying in probably the most gruesome way possible
Even if this theory were full canon, there is no guarantee that Deku or Decay's original holder would have manifested itself in the exact same way. Deku or the original Decay user might have merely had a Matter-Formatting Quirk that Ujiko twisted into Decay. Also, we have to take Shigaraki's instability into account. His entire family failed him: Abusive Dad, Ineffectual Mom, Blame-Shifting sister and too-comfortable grandparents may have meant that his Quirk, originally his or not, came out in the worst way possible due to his rage and upset - or that AFO triggered it remotely somehow.
Deku must have his own quirk. His body is literally tearing itself apart when he first got one for all. If the person isn’t modified like a nobu then there body could reject the quirk given. All might didn’t have a quirk and inherited stock pile. Deku quirk might be hidden after all.
The predecessors already explained why the next user of OFA needed to be quirkless and Deku ended up being the last due to the quirk being to powerful. OFA is a stock pile quirk which builds up each time its pass down. The quirk itself increases the users physical capabilites and their quirk. The 4th user claims he die of old age due to the effects of OFA after building it up for the next generation. Now with OFA fully develop and pass down to Deku, the quirk had awaken.
you know the decay quirk theory is fun and all...except for the large age gap between the 2. deku wouldnt have been around the time shigaraki killed his family
@@jansab7430 exactly and quirks tend to appear a few years later, I doubt there are many kids who are born with their quirks, doesn't mean there aren't any but his parents quirks also raise a point
@@justaguywithagoodphoto4801 It would work if the AFO is Deku's dad theory turned out to be true. AFO was there at Dekus birth, stole his quirk, gave it to Shigaraki. Deku's dad is literally always away for "business" and we have never heard from him. Fuck, his wife and child and the rest of his home country are in peril and we still haven't heard from him somehow? And obviously the fact that Horikoshi is a massive Star Wars fan and has multiple things in the story that are related to it, such as city names. Just gotta wait for the "I am your father" scene.
I think if he did have a quirk it would be kinda like a 3rd generation pyrokinetic in fire force where he can basically create and control flames at will. His dad was said to have had the ability to breathe fire and his mom has small level telekinesis, so if Deku had somehow manifested a power quirk from the combination of these 2 then it was probably the ability to create flames and manipulate them (like not just shoot fire, basically fire bending)
@@sunblobian ehh, his dad’s flames were supposedly small so not really. It would still be stronger than some other members of 1-A though, and he could possibly be a counter to flame quirk users by using their flames against them
I always thought it was crazy that Dr. Ujiko was, not only Izuku's doctor but also the person that told him that he was quirk-less. I really hope we get some sort of explanation for this!!
@@yusufarslan1 i can't "expect" to be told anything. I simply think that it would be cool if the fact that him being Dekus childhood doctor plays into the story somehow.
The theory Deku's original quirk was decay is good but most likely not the case. With his mother being able to levitate small object and father who breaths fire, the chances of decay spawning from those combinations is unlikely. However, there's a chance Deku's quirk could've been some sort of "Fire Bending" as it would be the perfect quirk that combines both of his parents. Further evidence for this is with fire quirks being so common in the MH universe, a quirk that could control a large majority of peoples quirks (Including the current #1 Hero) it makes since why AFO would want to steal it. That's my theory at least.
Yeah but he’s Quirkless when he got OFA because of that he’s empty cup like All might and if he did have a quirk the previous users wouldn’t know because he didn’t have OFA and non of them know. If he had a quirk he’s cup half full meaning he’ll die young because he had a quirk and it’s added onto OFA but if it was stolen it would made him empty cup and won’t die young to OFA and won’t be adding a Quirk to it.
The Theory I go off of is Hishasi is actually All For One which would explain why he has been absent Izukus whole life and would explain why Garaki was the only doctor who told Izuku he was quirkless because AFO stole it and Garaki works with AFO. And on top of all that Horikoshi was a MASSIVE Star Wars Fan and it’s probably going to pull a “I am Your Father” moment between AFO and Izuku
Although in the show the doctor said that if Deku had a quirk it would be some sort of alteration or mix of his parent’s quirks. My theory is that if he had a quirk when he was born he’d have Pyrokinesis, judging from how his mom has telekinesis and his dad can breathe fire. (Just for those who don’t know, pyrokinesis is the ability to make things randomly combust into flames)
@@Chara_Dreemurr1 He wasn't, his quirk just has a high drawback that makes it hard to use, and his laser is weak, that's why he needs the belt to magnify it. Or do you not remember the whole "I know your secret" bit? That was literally an episode. Go back and rewatch the series again.
I thought it was the regeneration quirk since that tracks better with the Izuku / Shigaraki timeline and Dr. Garaki's rate of "stockpiling" good quirks that could be useful, since Izuku's would show up at ~5, Shigaraki would be 10 (already had the Decay quirk) and then Dr. Garaki is free to still take Izuku's quirk for All for One either way.
My theory is that Deku does have a quirk but his quirk is so non-invasive that it barely qualifies as one much like how the first wielder's quirk fused with AFO's gift. His mother manipulates objects, and his father controls fire. Deku's genes melds with OFA and allows him to manipulate the fire within himself...Since OFA has been decribed as a burning flame since all the way back in S1. That would also be why Deku is the first user to control the quirks of previous users, previous users could merely be empowered by the flames of OFA but Deku's different, his DNA allows him to become that Flame, to control it beyond his predecessors.
Only that everyone with a qurik can be identified with the method that ujiko used. So, deku currently doesn't posses his own qurik if he ever had one. Back then to the time of OFA youth, there probably wasn't the method known to identify qurik wielders.
Also, we Already know why deku can use the quirks of the former wielders, and why the wielders before couldn't do this. It's simply because of the qurik singularity. OFA evolved over time, and the user before deku trained the quirk so, that the next user could become stronger. This is why deku is hurt badly by the quirk, because it's so complicated that the body can't handle it.
Nah, Deku’s quirk cannot be decay. Shigaraki’s backstory explains it, his power was clearly decay when used and he met AFO After he used it on his family
The doctor literally said at the beginning of the show that there was a certain joint in the pinky toe that if it was there, you don't have a quirk. That it was a study made if a distinction was found between quirkless and quirk children and it was that joint. This is gone over in the flashback episode in one of the first episodes.
You do realize that it was the same doctor that was working with ALL FOR ONE, the guy that can steal quirks, and was able to help give the Nomu multiple quirks Tho I don’t think decay was Deku quirk I think it was likely some form of fire manipulation, since his dad was said to breath fire and his mom can move small objects
@@Soulintheshadows That doesn’t change the fact that this person also reported something that was considered a legitimate study in that time period. Asides from that, AFO would’ve needed to be in direct contact with someone to steal a quirk. Also shigaraki is 5 years older than Midoriya, the timeline of when Shigaraki got his quirk to show doesn’t line up correctly with when Midoriya would’ve had his taken. Would’ve been a wild theory if true but doesn’t line up either way.
@@Cubanburrito305 Technically, it's plausible that the doctor was the one who developed the theory himself. He could have made up the pinkie toe theory just as a cover for stealing quirks from babies. In any case, he could have always just faked the x-rays. The author did choose to make midoriya'a doctor one if the most despicable beings in the series, so he definitely had some porpuse to do so. Then again the porpuse could be sth as simple as just showing how bad an innocent looking person can be. I doubt that this is what the mangaka was going for, since no one really adressed their relationship. The hospital raid was probably the best moment to adress that, so that's probably not what it was.
@@Cubanburrito305 Sure it's a legitimate study, however, how do we know the x-rays he showed were legitimate? He is the director of the hospital, it can't be difficult to falsify the x-rays. I believe Deku's quirk was taken, it wasn't decay though. Maybe we won't find out what it was, just that he's another victim of AFO before even getting involved with OFA.
Actually shigarakis quirk appeared when he was 5 bc his itch was starting bc he was near heros, nice people or people that make him stress (i think) so it started bc his father would beat him if he talked heros so when his sister showed him a picture of his dad as a kid with his mom aka all mights master but later his sister told his dad it was him so his dad put him outside and he was with his corgi and he was crying and it seemed like he was scratching his corgi but then thats when he stopped scratching corgi then it started to decay after his sister came outside to say sorry but she saw blood or the corgi so she ran shigaraki ran after her he grabbed her dress and she decayed then his mom,grandma,and his grandpa came outside to see what was happening then they saw the blood and froze then he ran to them and touched them so they decayed then his dad was in the back and got a rake and started hitting him with it and this time he touched him on purpose by putting his hand on his face but then the house was collapsed when he got out of the house then he said that he stopped itching so he was walking on the street and everyone passed him so then he was in the alley way and then that was the first time he met AFO pls like this took forever
I think if he really had a quirk it would be like something similar to "fire manipulation to some extent" or something like "fire telekinesis" or whatever
My theory:- Deku had a passive (dormant )quirk - His quirk was that he could use multiple quirks But he couldn't use it because he couldn't get multiple quirks And when Dr. Stole his quirk , he gave them to nomos Everything fits as the nomos can have multiple quirks but why didn't they make the nomos before (Dr. Is 100+ years old but they only send the first nomo when deku joined UA high) I think he stole deku's quirk and they tested in it for some years and finally were succesful in making nomos Another reason for This theory:- Why can only deku use past OFA users quirks and why didn't other past OFA users use them When eri reversed deku's body when he fought with overhaul We know that eri can get a stolen or erased quirk back (as she got lemillion's quirk back) When she reversed deku , he got his old quirk (using multiple quirks)back And shortly after that he gained acces to blackwhip and so on. OFA already had all other quirks but no one else could use it because they lacked deku's quirk So , how was this theory. It's not actually completely mine , I read it somewhere (I don't remember) and I added some stuff myself
I don’t think the eri part makes sense, since her quirk is rewind it would have gotten rid of one for all unless the quirk was stolen after izuku got one for all? I haven’t watched the overhaul arc in a while so I might be getting eri’s quirk wrong.
@@lalordpheonix106 she could erase any other quirk but OFA is different Like she can't bring back all night's OFA . So she can't erase it either But his own quirk was not part of OFA , so she got it back

I've got a simple explanation here that you guys aren't going to like. Maybe JUST MAYBE Ujiko had to perform ACTUAL responsibilities as a doctor to keep his cover up for decades so he was just a regular doctor for Deku and Deku truly was just quirkless. As for reasons this 99.99% for sure the true reasoning, 1. Deku mentions nothing about "hey that was my doctor" 2. The doctor never mentions to anyone "hey that's the kid I took _____ from. He shouldn't have a quirk" 3. It most certainly is NOT Decay as timeline wise it doesn't work as Deku wasn't born yet 4. IF Deku had a quirk it would have been a combo of fire breathing and attraction and we've seen nothing even REMOTELY close to that description shown by anyone let alone AFO or Shigiraki 5. In grade school Deku does appear to be the only one who is quirkless which based on the statistics of quirkless individuals, checks out 6. In order to not raise suspicion, Ujiko could not take too many quirks as the % of quirkless individuals would rise drastically. That would cause an investigation, people would see his hospital had an unusually high number of quirkless diagnosis, that would then center the hospital as the focus of their investigation, thus eventually leading to Ujiko getting found out and ruining all of AFO's plans. I'm sorry guys, as much as we love to theorize, Deku just WAS born quirkless and it's just fate, kismet, destiny, luck, happenstance, etc. that Ujiko was the doctor he saw. There's just too many logical fallacies to say Deku had a quirk and it was stolen which in turn would harm the story rather than enhance it.
One theory I like is that Deku developed the All For One quirk cause his father is AFO. It had to be taken to keep AFOs secret cause if a child was found to have the same quirk then it would give Allmight a lead as to AFOs identity. Also if anyone says "but Dekus father has a fire quirk!" AFO might have only pretended to only have the fire breathing quirk around his wife.
I actually like the idea that the basis for Super Regeneration actually came from a quirk stolen from Deku. That would mean the nigh-inviinicbility Shiguraki, All For One and all the Nomu's have would've actually been engineered from Deku, ultimately making him one of the main causes for all of the Hero's suffering.
His original quirk was a mix between Half hot Half cold, and decay. Since AFO knew it would drive Toya to the side of darkness he used the doctor to steal Deku’s original quirks and give it to Shoto when nobody in the totoroki house was aware, and since endeavor was already trying to create that quirk he didn’t notice. Deku’s dad already had a fire based quirk so it makes sense. AFO gave Deku’s remaining power to Shigaraki because he knew shigaraki couldn’t control it without the guidance of Nana Shimura who he still resented the legacy of
Guys there is one fact that throws that theory out of the window. In the beginning of the anime we are being told that all quirkless have 5 toes. And Izuku does have 5, so he couldn't own any quirk before OFA.
And who are you told by? The same doctor. You think there’s no significant plot point having one of the antagonist be the one to tell Deku this? I don’t think it’s decay but 100% Deku has a hidden quirk we don’t know about.
Actually, it was one less joint in the smallest toe of each foot. Deku's mother could have proven this if he was lying because she was the one he was informing of the matter. As she is Quirked herself, she would have known the lie for what it was. I'm sure the joints don't change if a Quirk is stolen. Now, the better counter of this theory: Deku and Shigaraki are at least 4 years apart in age. Izuku would still have been an infant by the time Shigaraki exhibited his Quirk.
I think deku had a mixture between his moms quirk and his dads which is fire breathing so deku could just make people float close to him with the same quirk as his mom and then set them on fire with the fire breathing which this seems very OP
Decay can't have been izukus original Quirk since decay was an edited copy of Overhaul's Overhaul Quirk! According to lore, there was someone [who I forgot the name of] who knew how to copy the Quirk factors using the original Quirk users' DNA and edit them. AFO edited a copy of Overhaul and got rid of its ability to restore and reform matter, keeping only its destruction capabilities and was given to shigaraki!
I like the theory that Deku did have a quirk and it was stolen from him, making him an empty vessel for One for All, and I also like the theory that Deku's quirk was Decay. A big issue with the Decay theory though is that if that is indeed the case, the time frame is extremely slim for it to be stolen and then transplanted to Shigaraki, as he is at least 4 to 5 years older than Deku. This means that it would have to have happened when Deku was a newborn for the timeline to make any sense and there is a possibility that time frame is just too slim for it to even be a possibility. The reason why I like the Decay theory however, is that it makes some kind of sense considering his parents' quirks. His father can apparently breath fire and his mother can attract small objects to her. Fire is a chemical reaction that breaks larger components into smaller, usually more simpler components, while the attraction quirk's specifics are unknown (telekinesis, gravity, magnetism, etc.) it can make sense that added to the fire quirk it acts as the vector for the break down of things touched without the actual chemical reaction (replacing the fire with whatever force is used)... or maybe there is a chemical reaction but its so efficient there is little to no heat waste in the effect.
I like to think Dekus original quirk would be fire immunity- it would be difficult to detect early on, causing them to seek out quirk counselling. It’s easy to remove with nobody noticing, and AFO would’ve been on the lookout for quirks to counteract the top few heroes either after or preparing for his fight with all might depending on the timeline also as far as we know bakugou didn’t burn him even by accident before he went to the doctor, and they were friends until that happened so he would’ve had his quirk and would’ve had the least amount of practice/control with it
On multiple occasions, they stressed that a body has to be made to handle its quirks. Shigaraki in particular was showing signs of quirk incapability in the first few seasons by constantly scratching his arms. I think a twist will come down where Shigaraki will succeed in using decay on Deku and it won't work because Deku was the original user. It will also turn Shigaraki against AFO, for when Shigaraki realizes that he was not born with Decay he will know it was AFO that killed his family.
The fact that quicks come at a early age and kids know they have powerful powers is crazy to me because if they wanted to they could destroy the whole house
YES!!! Thank you!!! I’m commenting “What about the bone structure of his pinky toe? 👀” under every comment not related to this 😂 I have no idea how it’s being overlooked by SO many fans of the show
You're talking about the same doctor who hid his identity and stole quirks for the biggest bad around? lol not a great source for reliable and trustworthy info. He would have to tell parents *something* about why their kid doesn't have a quirk after he's stolen it. Could have made up the theory, used his long life to propagate it - or if the bone thing is real, he could just show them a fake x-ray.
If this is true, I think the combination of his parents' quirks (telekinesis and fire breath) would be the ability to manipulate fire like a Water Bender manipulates water. Remote controlled fireballs, fire shields and walls, nullifying Endeavor, Dabi, Bakugo and half of Shoto...that quirk would be *devastating*
Correct me if I'm wrong but isn't Shigaraki like 20 something while deku is 16? That means the age difference wouldn't like up for Deku's quirk to be decay. I think it is possible that Deku's quirk was powerful tho. His mother has telekinesis, it may be weak and only work on small objects but what if his father also had a tk based ability? We know hair colors and shapes have a relativity to the users quirk and to be frank, not only is Deku's hair VERY green but it's also wavy, unlike his mother's. With a little bit of assumption, we can gander that his father may have had an AOE TK ability (since his wavy hair could suggest "waves" of TK) that could be limited by something like mass. Combining that with his mother we could get something like a stronger, faster acting force that could grab several objects from around him under a certain weight or mass scale. If we consider that, we essentially have a telekinetic force field that could be buffed by AFO's other quirks and it would also be extremely effective against just about anything since it's mass based on not necessarily force based. The only question that remains is where that ability would be now and since we don't see it in the story my theory is practically null and void.
His father had a green flame like quirk or fire breathing I think, his hair is likely green flames(the waviness) which may be dark from lack of his quirk
This might explain why Deku and Tenko have such a strong connection. Additionally, it may explain why we’ve never seen Demi’s dad and his mom shows easy signs of someone after being left suddenly by a significant other. The weight gain, extra cling, denial even to the point of psychological blockage in the form of amnesia.
First off, Shigaraki's an adult and Deku is a teen. Since Shigaraki's quirk manifested at the age of 5, Deku wasn't even born at the time. Deku's dad works overseas and provides for the family. And Deku's mom got fat because of the depression over Deku not having a Quirk. Also, the doctor can only cultivate quirks for a long time, and is immortal, but he doesn't have the ability to steal quirks
He explains that the quirkless have a missing joint in the pinky toe, which Deku has. Also Ujiko never had the power to steal quirks, he just has immortality, and can cultivate quirks over a long period of time using his lab. He wouldn't have any possible way to stea Izuku's quirk.
Thinking on the whole Missing joint thing, why is that never brought up again? I would find it highly unlikely that Deku never needed to get an x-ray after everything he did. Especially since he breaks his bones so frequently. I can see them trying to get Recovery Girl to do most of the checkups, but what about when that isn't possible? The movies for example, where Recovery Girl isn't nearby.
@@corruptsolstice340 While that is a concern... Doctor patient confidentiality is a thing. It may be a thing said off screen, but it's not like they'd tell anyone else unless absolutely necessary. Other than that, there's not that much of a point to bring it up.
@@blackrosethedemonlordlive patient confidentiality is a thing, but being able to have a medical record that travels with you doctor to doctor is vital.
What if Deku's dad was actually AFO son and being his son, deku had a very broken quirk which could prove beneficial for AFO so AFO asked the doctor to steal that quirk and tell deku he was quirkless. This should be a good plot twist In my opinion.
You see this would be an awesome theory,and the only thing Horikoshi had to do if he ever had to use it at the start of the series was just drop a line somewhere saying that “20% of humans don’t have Quirks,and a good 8%-10% of that 20%, live mostly in Japan” like the fact that Japan would have been the country to have the majority or a “higher” percentage of Quirkless people would have made of lot of sense. I mean the number is high enough that, if your Quirkless you would think more people like you are in the country, but don’t forget that Quirkless people self-termination might go down which would be a plus. And the Quirked population would complain less I mean Quirk bias would still be their, but maybe just a bit less.
Bc the doctor who told him he is quirkless is the same doctor who has been stealing, stockpiling, and engineering quirks for generations lol. Like why would any author reveal a late-game twist before the twist?
@@ElionVydell weird how I never mentioned the doctor saying he has no quirk. Also, you do realize the reason they went to the doctor was because his quirk never manifested, right? Like holy shit do any of you geniuses pay attention?
This makes complete sense (apart from the decay part) I always thought the doctor was just some random dude. Didn't realize it was ujiko so it's a big possibility he did something nefarious
In a theoretical way this could make sense due to the fire breathing quirk inherits spread damage and telekinesis affects movement. In a molecular scale, decay is the release of energy from tearing cells, tearing apart order into chaos. May not be real but it's a fun mind theory. In my opinion, with the singularity theory and how people tend to inherit quirks from family, decay is a wierd quirk for a kid whose parents have no predators for a quirk such as it.
This theory completely throws the one for all singularity and quirk plot. Also how the hell would Ujiko know what quirk Deku had, he didn't have search, quirks like decay which is a mutant are still like normal emitter quirks and wouldn't have any tells. And Deku would've remembered if he touched something and it crumbled Infront of him, especially doctor Ujiko
I mean CRISPR and stuff exists in real life and its not too far fetched to think that he can have a way to look at genes bc quirks are just mutated genes
@@akshayraju4610 CRISPRR is still in testing, and quirk cells aren't just mutated cells. The vestiges of OFA literally said that Deku was quirkless which let him cultivate OFA to its fullest potential in the Class A vs Tomura arc. And because when bodies evolve, they discard of organs, bones and more that aren't needed, like the second joint in the pinky toe. literally the first damn episode said this
It's possible that the doctor just stealed random baby quirks and tested them. AfO could always just confirm each quirk for himself so there was no need to wait for the quirk's awakening. The timeline barely fits. And there was clearly some point in him being Deku's doctor. I doubt it was just to show how even an innocent looking person can be so evil. The mangaka definitely has something planned about that. I mean, the author had us believed that tokoyami spend 15 years of his life without realizing that he could fly with his quirk. He is definitely the type of writer that makes up stuff about earlier parts of the story without foreshadowing as long as they don't contradict with anything established.
wait, i didnt even realize that 😮 i totally forgot about deku going to a doctor to check if he has a quirk and the doctor itself is an acquaintance to AFO, just realized that
I mean, one of the doctor's argument was that Deku has 5 toes, which apparently is something that people with quirks don't have anymore. They miss the pinky toe, which Deku does have,
Although the decay thing would be cool as well as this theory I think his quirk would most likely be something a lot weaker like his moms quirk (attracting small objects to her) or his dads which I believe is fire breathing (which is pretty cool) i could also imagine it could be some fire attraction quirk or some sort of mix. 🤷🏻♀️
I was imagine deku dad is like asuma sarutobi with cigar. Since his quirk is fire breathing? I thought like smog, to combust rather than just blowing fire tongue of flame like dragon do (that's lame.)
Interesting, but it's not likely he had decay given quirks are related to 2 things; personality & hereditary mental history. Deku's mom has water based abilities much like his explosive childhood friend has a bombshell of a mom. This is also a tragic concept as well given OFA accelerates your life span & if he had one prior it's possible he will die. Also, antigravity + thrust could be the source of decay; pushing atoms apart like smart atoms from Invicible.
@@amvnations4413 Apologies, that's what her abilities were in another universe's cannon. Reincarnation is funny like that & can be a little annoying to see the differences. It was cool to see her make bubbles though but in this universe she can make things float & his father can breathe fire. That aside, still a valid thought towards my point.
His quirk being stolen is actually really plausible. The quirk itself being decay is a little less likely but at the same time it would fit the narrative really well. I wouldn’t be surprised because MHA has some pretty solid writing and a lot of people overlook that
deku is 0-1 when his quirk gets stolen. Shigaraki is given the quirk by all for one to kill his family, that's why it went out of control after all for one brings him back home. It also explains shigaraki's constant scratching because the quirk was rejecting his body, because it wasn't his.
@@NerdCoems people are theory crafting decay isnt his orignial quirk but one given to him, by afo , it happened the same day he was lost and afo brought him home. Thats why his powers went crazy and he killed his family. Also his quirk might not have been doing too well in his body, since he was always scratching and itching, it looked like decay was slowly destroying him
Nah, Deku had an extra joint in his pinky toe. He was born quirk less. I like the idea of him being born quirk less, it gives him an extra appreciation for being gifted with a power the likes of one for all.
I'm pretty sure Deku was the original owner of the Super Regeneration quirk. That would explain why he wouldn't know about it, if he never suffered a major injury, and it would explain how he's able to just destroy his own body willy-nilly while everyone else thinks he's crazy.
It makes sense, shigaraki's body clearly is rejecting decay. We don't see too many other individuals with native quirks that do damage or have a backlash
@christophercardoza2872 No, so think about it, the dry skin, the need to itch . Feeling gross constantly. His body was not compatible with decay at all. Theoretically, they could have taken the deku's quirk at any point, not just when it would have manifested.
@Clayton Talesfore or decay is why he's always itching. Not that they aren't compatible. He's always nervous and the quirk itself can cause the itch because it's decay
They do though? Shigaraki is 21 which means when he was 5 deku should have just been born or would have been a baby, assuming he had his quirk at a young age like a few months old or just born(you can have a quirk at birth, any age under 4 can develop a quirk) he could have had it stolen. It lines up perfectly. If he had his quirk stolen as a baby it would line up with when Shigaraki gets his quirk and explains why Ujiko decided to be his doctor and lie about his quirk. His explanation about the toe joint is just bs he made up to tell parents of quirks he stole.
@@detectivesmokeguy1672 Why would he? If Ujiko is collecting quirks from hundreds of kids because of his job as doctor how would he know every single kid and parent?
@@Williamwillow_still wouldn’t make sense. Shiggy wasn’t give his quirk. If he was then AFO would be the one who’d have to have given it to him. If that’s the case his initial dialogue wouldn’t make sense
It's possible. Maybe it's the reason why he has a connection with shigaraki. Why their fates intertwined. Then a major twist in the end where Deku is actually immune to decay being he is the original owner of it and by God's grace, saves everyone with this asspull. But to be honest, it's somewhat of a good foreshadowing of when shigaraki had his hands on his neck explaining how it works and all during that time.
@TuxedoMask189 isn't it weird? Deku got bullied by bakugo at a young age and now that karma is back at bakugo by shigAFO and how futile it was to fight him with his quirk.
Love this theory, it can even be expanded upon. Deku’s toe that was seen in the X-ray is prevalent bc only those with very special/powerful/rare quirks have this in common! I could go into meticulous detail but I have a word limit
![Mha/Bnha Villains (+ Pro Heroes) React to Izuku Midoriya’s Life || Manga Spoilers || Full Ver]](http://i.ytimg.com/vi/N_gweNTLa2c/mqdefault.jpg)
Deku's mom has the ability to attract objects, while Deku's father can breath fire. Deku's mom+ Deku's dad= ability to attract hot things. Garaki stole it to build his own harem.
dream quirk fr
Worst theory joke ever
So true
..
Rizz quirk XD
I mean, Dr. Ujiko finding Quirks to steal through his appointments is basically confirmed since one of Deku and Bakugou's childhood friends was used in one of the Nomu. It's safe to assume he is the go-to Quirk Doctor in the area and their friend saw him at some point as well.
I think even one of them was he’s grandson
@Dylan Martinez same kid. He used his grandson to make the winged Nomu that Stein kills.
The Nomi was his grandson so not really comfimed that he User kids from his apppintments
I have a different theory on it. I think he didn't have one at all still. Just like OFA effects the body so it is better on a quirkless body, I think AFO does too. So Ujiko, who is creating Nomu as bodies that can hold multiple quirks, was searching for children without quirks to become a new body for AFO. Deku didn't have it stolen, Deku was getting sized up to be a new container.
I like it. And also isn’t that OFA in a nutshell, multiple quirks that get sent to one person, so that means I see this as very likely.
That's actually a good theory because izuku can't have decay as his quirk because none of his parents have a decay type quirk and no were near to being the same
Ooooh that would have been interesting. An empty vessel to just load up with quirks. Probably would have shaped up to be a deadly Nomu
More people need to see this, it makes perfect sense!
@@IDK-km7vd I hope you didn't forget that quirk can mutate just like in Eri's case non of her parent have the quirk that resembles or close to rewinds at all yet her quirk came out as the one we seen so it also make sense that deku COULD'VE been the original owner of "decay" 😅
4 problems here.
1. Deku is younger than Shigaraki, so either there's time travel involved or it didn't happen.
2. Deku's mom had limited telekinesis and his dad could breathe fire.
Since quirks have been shown to be passed down and combine in some fashion, I highly doubt those two combined into the ability to _disintegrate things on touch._
The only exception being a quirk mutation, but those are very rare as far as I'm aware.
3. This theory would also imply that the doc found out about, identified, and orchestrated a way to steal the quirk before it even *_manifested_* considering that there was *_zero_* mention of Deku disintegrating things as a child.
It's a 5-point contact quirk. No way that Deku wouldn't have met the activation requirements at *_least_* once before the doc could take it.
4. It conflicts with lore. According to the anime, the entire reason that Deku manifested the multiple quirks of OFA is *_because_* he was quirkless.
You have to be quirkless to wield the full power of OFA. I believe they even specified quirkless and not just having a quirk stolen.
Edit: Revised point 2 since I have been informed of a few things I missed. I also added another point that I thought of and made it easier to read.
Actually quirks can skip generations kind of, as you can get your parents parents quirk and their parents parents but you get the idea, and I do agree there are reason to this theory is just that
his quirk got stolen. so he quirkles
@@ordinaryone2833 It's not the same.
The reason he's able to manifest all 6 or so quirks of OFA is because he's never had a quirk before _at all._
That's the explanation they gave in season 6 anyhow.
@@ventusargentum9957 then why didn’t All Might develop the other quirks when he was born without one
@@wickeli The in universe explanation is that the quirk wasn't ready or Deku had some special talent for it.
Out of universe however, we have no idea other than it's probably just because the writer's thought it was cool.
Why they didn't just make All Might have a quirk or something we may never know.
So long story short: that is how it works, but why it worked for one and not the other is a mystery.
More likely than this theory is that the thematic reason for Garaki being the doctor to tell Deku he was quirkless was that Deku narrowly avoided becoming someone who they would kidnap to turn into a Nomu. Because they confirmed that the one nomu who had wings during the stain arc was actually the kid with wings from Deku and Kacchan's first flashback scene in season 1. It's possible that most of the kids in that area all went to the hospital Garaki worked at and were therefore all seen by him as their quirk related doctor.
Not to mention that this theory completely ignores the reason Garaki says Deku is probably quirkless which is that he has that pinky toe joint. So unless Garaki, unbeknownst to Deku or his mom, gave him an extra pinky toe joint then it's probably bunk.
Then why didn't he take Katsuki? 🤔
@@Randus1058But wouldn't the OFA vestiges have known somehow that Deku had a quirk. They showed him Shirgaraki's past. Why is it that they don't know that he had a quirk.
@@Randus1058Because it would be suspicious if a kid with an explosion quirk and assuming he uses it daily suddenly lose his quirk after the hospital visit. Plus, I don't think it is necessary to send him to the hospital since quirk is a natural thing that happens in daily life unless the quirk itself hurt the user like Dabi's quirk.
Or that pinky toe stuff was just bogus the doctor made up so he would have a "reason" to give deku's mom
@@Randus1058personality wise Bakugo would probably blow up the hospital before agreeing to a checkup
problem is we see midoriya's back story and shigarakis, shigaraki is an adult, and midoriya's a teen. meaning its literally impossible when midoriya wasnt even alive when shigaraki's quirk manifested
they have a 5 year age gap. If afo stole it from baby Deku it’s *possible*. Especially considering that Shigaraki’s quirk came in late.
@@mimikyu__- how tf he knows about ability untill its awaken .
@@harman7978 i think it’s like: if people are born with their quirks but they’re dormant until they’re about 4-5 then it should be *possible* for AFO to steal a quirk from a kid who hasn’t developed their quirk yet. I don’t think it’s very likely, but it is a possibility.
I was looking for someone to say this. These theories are so dumb. They would just tell us, it wouldn’t be a secret lol
@@mimikyu__- I'm pretty sure it's possible to steal quirks from babies who haven't manifested it yet. But then the question, how does AFO knew what those unmanifested quirks are? Like, Izuku's parents have fire breathing and weak telekinetic quirk and a child's quirk is usually the same/similar to their parents (Jirou Kyoka for example) or a combination of their parent's (Bakugo Katsuki). So logically, Izuku's quirk should be something related to fire or telekinetic. Not something as wild as decay.
I actually once considered this possibility, but Deku was almost guaranteed quirkless when the analysis showed that he has two joints in his pinky toe -- whereas people who are born with Quirks only have one joint. Then again, it is also possible that the Doctor lied about the checkup results.
Maybe the once with two joints has more powerful quirks and he steal from the once with two joints in the pinky
Or he was modified like a nomu
I love how nobody stops to think that maybe the doctor used someone else's x-ray... he was literally helping afo kidnap and steal people's quirks, but the x-ray is the Smoking Gun that he would have never faked?
or it just fact, also the pinky thing can easily be test at home, you can grab your foot and check the joints just like your hand joint only pinky toe tip joint might just be a nub.
it not rocket Science it basic biology, also it actualy a Scientific theory that humans will lose the pinky joint just like the vestigial tail bone but not proven yet.
@@nightterror007 The cray would be available to any doctor who would have seen Deku. And he saw a lot of them and probably got xrayed a lot
So here’s why I think he didn’t have a quirk. His father had a fire breathing quirk, and most fire users have some sort of resistance to burning some immune some taking a lot of fire to burn. So if his dads quirk was fire breathing and Deku inherited the flame part of it then shouldn’t Deku also be mostly immune to burns? But as we see in the very beginning of UA when Deku fights Bakugo, Deku sustains some pretty severe burns so likely he was just born quirkless.
Fire breathing would most likely give resistance to mouth burns and that’s if he got any from his father. Dabi’s issues with his fire is also a problem so there is a chance there is no resistance. Bakugos quirk is explosions which is different than fire as well
@@YukiA816 Yes but his mothers quirk was ice, and he got the immunity to cold. And if a person with fire breathing for a quirk had only the inside of the mouth immune the lips and a lot of the face would get burned badly
He could also be just resistant and not immune. After all, explosions at even a small scale should leave at least some small scars, but Deku doesn't have any scars from the explosions over the years
@@barretthegamingbear708 I don’t think that’s the case either, because deku has sustained a lot of damage of many types over the years at UA, but still has no scars from those. His current scars are literally just from ofa. So either he has a weird healing where he has no scars form except from very specific things, or it’s just illustration. We will probably know the answer when the final chapters are released
@@barretthegamingbear708 also even small explosions can leave huge holes, so I think bakugo has some special kinds of explosions.
Deku was probably not even born when shigaraki was 5 😭😭
Ikr
He was 20, so probably not Deku's quirk.
In season 1.
That’s what I thought
Or just born. If Shigiraki is 20 at the start of the series, and the UA 1st year age is 15...
Decay doesn’t make sense unless Izuku was like Eri and had a Mutated Quirk Factor or if AFO is really his Father (I don’t subscribe to that theory). If Izuku’s Dad really is just Hisashi Midoriya with a Fire Breathing Quirk then a Fire Based or Telekinetically Based Quirk makes more sense…
Decay also doesn't make sense for Shigaraki either by your own logic. Whether it's Dekus quirk or Shigarakis it's a mutated quirk.
Aint Shigaraki much older then deku anyway
Well if you mixed flame control (fire breathing) and small scale telekinesis, you could have a sort of "decay", fire burning everything to ashes. That along with the quirk singularity could yield decay. I don't subscribe to this theory but it was always my thought if it was the case that deku did have a quirk.
I think people are forgetting shigarski is way older than deku
Well the way fire works in the most simplified sense is it accelerates entropy by speeding up the molecules of whatever is on fire. So fire control and telekinesis would actually make sense to be the parents of a mutated decay quirk user. The more I think about it the crazier this theory gets. Also in regards to shigaraki being older than deku, there is the possibility that Dekus father was working with AFO to get with Dekus mom because they knew based on research that combination of genetics could develop a strong quirk, Dekus father develops feelings for his false family and tries to go up against AFO and gets bodied hard. Ain’t no way if his dads just a bum he hasn’t seen deku in the papers like bum dads in real life coming back into their kids lives when they win the lottery or become successful, he is capital D dead or a villain. My point is Deku was born around the time Shigaraki developed his quirk under mysterious circumstances, and the doctor could’ve just made something up to throw them off the trail completely.
Ah yes, the doctor after stealing a quirk he didn't even know
Went *BACK* in time to give it to shigaraki and the quirk manifested at the same age Deku's was stolen
Unless the doctor has a Uber powerful quirk he doesn’t disclose all its potential where he can steal quirks, not able to manifest them into physical ones he can use but his quirk permits him to travel time even say just astral like with the ability of gifting quirks he has absconded. This is just a theory and theory takes imagination, intelligence and creativity particularly in a story about based upon beings with a multitude of abilities, which for an anime fan you seem to surprisingly lack and want your stories fed to you in absolute’s

Your comment isn't adding up to much tbh
No.1 The doctor works for all for one. No.2 The dude that sent tenko home was wearing a tuxedo and a fedora later we can conclude that that man was all for one because later we can see afo who was wearing a tuxedo and a fedora take dabi in. The appearance of the mysterious man looked exactly like afo. The doctors quirk has a quirk that can live twice the amount as a normal person can live. We can also involve the theory that afo is dekus dad meaning afo stole his quirk when he was very little then left the family then gave the quirk to shigaraki
It would honestly be so tragic if deku developed decay I don’t think my heart could take someone as precious as mama Midoryia dying in probably the most gruesome way possible
Even if this theory were full canon, there is no guarantee that Deku or Decay's original holder would have manifested itself in the exact same way. Deku or the original Decay user might have merely had a Matter-Formatting Quirk that Ujiko twisted into Decay. Also, we have to take Shigaraki's instability into account. His entire family failed him: Abusive Dad, Ineffectual Mom, Blame-Shifting sister and too-comfortable grandparents may have meant that his Quirk, originally his or not, came out in the worst way possible due to his rage and upset - or that AFO triggered it remotely somehow.
I have a feeling he would use it to destroy rubble and debris
Deku must have his own quirk. His body is literally tearing itself apart when he first got one for all. If the person isn’t modified like a nobu then there body could reject the quirk given. All might didn’t have a quirk and inherited stock pile. Deku quirk might be hidden after all.
He can't have or else he wouldn't have been able to awaken one for all and reach its true potential. Something only a quirkless user can do
The predecessors already explained why the next user of OFA needed to be quirkless and Deku ended up being the last due to the quirk being to powerful. OFA is a stock pile quirk which builds up each time its pass down. The quirk itself increases the users physical capabilites and their quirk. The 4th user claims he die of old age due to the effects of OFA after building it up for the next generation. Now with OFA fully develop and pass down to Deku, the quirk had awaken.

The theory Deku's original quirk was decay is good but most likely not the case. With his mother being able to levitate small object and father who breaths fire, the chances of decay spawning from those combinations is unlikely. However, there's a chance Deku's quirk could've been some sort of "Fire Bending" as it would be the perfect quirk that combines both of his parents. Further evidence for this is with fire quirks being so common in the MH universe, a quirk that could control a large majority of peoples quirks (Including the current #1 Hero) it makes since why AFO would want to steal it. That's my theory at least.
You don’t only get quirks from your parents it’s confirmed that children could develop quirks entirely different from their parents
i mean we dont know if breathing fire is actually his dads quirk tho… i kinda believe the theory that AFO is dekus dad too so
Attract and accelerate hot Oxygen molecules to decay things just like oxide does
Ujiko was the leading doctor in quirk studies. Diagnosing a quirkless kid would have been a routine part of his public life
No. the entire reason Deku is able to talk with the previous holders of ofa is because he was born quirkless.
They said he was quirkless when he got one for all and that's why they can talk not that he was born that way
Yeah but he’s Quirkless when he got OFA because of that he’s empty cup like All might and if he did have a quirk the previous users wouldn’t know because he didn’t have OFA and non of them know.
If he had a quirk he’s cup half full meaning he’ll die young because he had a quirk and it’s added onto OFA but if it was stolen it would made him empty cup and won’t die young to OFA and won’t be adding a Quirk to it.

And on top of all that Horikoshi was a MASSIVE Star Wars Fan and it’s probably going to pull a “I am Your Father” moment between AFO and Izuku

Well, that plan backfired, now he's got one for all, a MUCH more powerful quirk.
Although in the show the doctor said that if Deku had a quirk it would be some sort of alteration or mix of his parent’s quirks.
My theory is that if he had a quirk when he was born he’d have Pyrokinesis, judging from how his mom has telekinesis and his dad can breathe fire.
(Just for those who don’t know, pyrokinesis is the ability to make things randomly combust into flames)
Shigaraki casually Had a rash and itch that started to appear, Which could be a non body compatibility issue like Aoyama or dabi
And aoyama was quirkless.
His itch was from stress from his father
@@Chara_Dreemurr1 He wasn't, his quirk just has a high drawback that makes it hard to use, and his laser is weak, that's why he needs the belt to magnify it. Or do you not remember the whole "I know your secret" bit? That was literally an episode. Go back and rewatch the series again.

Will o' Wisp
I thought it was the regeneration quirk since that tracks better with the Izuku / Shigaraki timeline and Dr. Garaki's rate of "stockpiling" good quirks that could be useful, since Izuku's would show up at ~5, Shigaraki would be 10 (already had the Decay quirk) and then Dr. Garaki is free to still take Izuku's quirk for All for One either way.
Honestly that scene of deku gives me serious mad villain feeling
What was said: According to a theory
What I heard/saw: According to Chapter 408 💀
When I started reading the manga that was first thought dr ujiko for sure stole deku’s quirk
My theory is that Deku does have a quirk but his quirk is so non-invasive that it barely qualifies as one much like how the first wielder's quirk fused with AFO's gift. His mother manipulates objects, and his father controls fire. Deku's genes melds with OFA and allows him to manipulate the fire within himself...Since OFA has been decribed as a burning flame since all the way back in S1. That would also be why Deku is the first user to control the quirks of previous users, previous users could merely be empowered by the flames of OFA but Deku's different, his DNA allows him to become that Flame, to control it beyond his predecessors.
This one is pretty fair.
Only that everyone with a qurik can be identified with the method that ujiko used. So, deku currently doesn't posses his own qurik if he ever had one. Back then to the time of OFA youth, there probably wasn't the method known to identify qurik wielders.
Also, we Already know why deku can use the quirks of the former wielders, and why the wielders before couldn't do this. It's simply because of the qurik singularity. OFA evolved over time, and the user before deku trained the quirk so, that the next user could become stronger.
This is why deku is hurt badly by the quirk, because it's so complicated that the body can't handle it.
Incredible theory but i don't really think that's the case
@@zrrttt9205 it's debunked easily, so not incredible
Nah, Deku’s quirk cannot be decay. Shigaraki’s backstory explains it, his power was clearly decay when used and he met AFO After he used it on his family

@@havenvr5830 can be considered pretty lame and overused too.
The doctor literally said at the beginning of the show that there was a certain joint in the pinky toe that if it was there, you don't have a quirk. That it was a study made if a distinction was found between quirkless and quirk children and it was that joint. This is gone over in the flashback episode in one of the first episodes.
You do realize that it was the same doctor that was working with ALL FOR ONE, the guy that can steal quirks, and was able to help give the Nomu multiple quirks
Tho I don’t think decay was Deku quirk I think it was likely some form of fire manipulation, since his dad was said to breath fire and his mom can move small objects
@@Soulintheshadows That doesn’t change the fact that this person also reported something that was considered a legitimate study in that time period. Asides from that, AFO would’ve needed to be in direct contact with someone to steal a quirk. Also shigaraki is 5 years older than Midoriya, the timeline of when Shigaraki got his quirk to show doesn’t line up correctly with when Midoriya would’ve had his taken. Would’ve been a wild theory if true but doesn’t line up either way.
@@Cubanburrito305 Technically, it's plausible that the doctor was the one who developed the theory himself. He could have made up the pinkie toe theory just as a cover for stealing quirks from babies.
In any case, he could have always just faked the x-rays.
The author did choose to make midoriya'a doctor one if the most despicable beings in the series, so he definitely had some porpuse to do so.
Then again the porpuse could be sth as simple as just showing how bad an innocent looking person can be. I doubt that this is what the mangaka was going for, since no one really adressed their relationship. The hospital raid was probably the best moment to adress that, so that's probably not what it was.
@@Cubanburrito305 Sure it's a legitimate study, however, how do we know the x-rays he showed were legitimate? He is the director of the hospital, it can't be difficult to falsify the x-rays. I believe Deku's quirk was taken, it wasn't decay though. Maybe we won't find out what it was, just that he's another victim of AFO before even getting involved with OFA.
@@Cubanburrito305 the doctor lived huundreds of years, he could have made that study up. Its kind of like how a lot of studies are made up nowadays
Actually shigarakis quirk appeared when he was 5 bc his itch was starting bc he was near heros, nice people or people that make him stress (i think) so it started bc his father would beat him if he talked heros so when his sister showed him a picture of his dad as a kid with his mom aka all mights master but later his sister told his dad it was him so his dad put him outside and he was with his corgi and he was crying and it seemed like he was scratching his corgi but then thats when he stopped scratching corgi then it started to decay after his sister came outside to say sorry but she saw blood or the corgi so she ran shigaraki ran after her he grabbed her dress and she decayed then his mom,grandma,and his grandpa came outside to see what was happening then they saw the blood and froze then he ran to them and touched them so they decayed then his dad was in the back and got a rake and started hitting him with it and this time he touched him on purpose by putting his hand on his face but then the house was collapsed when he got out of the house then he said that he stopped itching so he was walking on the street and everyone passed him so then he was in the alley way and then that was the first time he met AFO
pls like this took forever
I think if he really had a quirk it would be like something similar to "fire manipulation to some extent" or something like "fire telekinesis" or whatever
My theory:-
Deku had a passive (dormant )quirk - His quirk was that he could use multiple quirks
But he couldn't use it because he couldn't get multiple quirks
And when Dr. Stole his quirk , he gave them to nomos
Everything fits as the nomos can have multiple quirks but why didn't they make the nomos before (Dr. Is 100+ years old but they only send the first nomo when deku joined UA high)
I think he stole deku's quirk and they tested in it for some years and finally were succesful in making nomos
Another reason for This theory:-
Why can only deku use past OFA users quirks and why didn't other past OFA users use them
When eri reversed deku's body when he fought with overhaul
We know that eri can get a stolen or erased quirk back (as she got lemillion's quirk back)
When she reversed deku , he got his old quirk (using multiple quirks)back
And shortly after that he gained acces to blackwhip and so on.
OFA already had all other quirks but no one else could use it because they lacked deku's quirk
So , how was this theory. It's not actually completely mine , I read it somewhere (I don't remember) and I added some stuff myself
I don’t think the eri part makes sense, since her quirk is rewind it would have gotten rid of one for all unless the quirk was stolen after izuku got one for all? I haven’t watched the overhaul arc in a while so I might be getting eri’s quirk wrong.
@@lalordpheonix106 she could erase any other quirk but OFA is different
Like she can't bring back all night's OFA . So she can't erase it either
But his own quirk was not part of OFA , so she got it back

I meant her power is strong and if she uses her quirk on someone for long time his / her body reverses back to the time when he / she didn't have a quirk
But that's not the case for OFA
Cause if it were she would have restored all might's quirk
And her quirk doesn't heal the body it reverses it back to a time when it wasn't injured
@@renn1752 she can’t restore all might’s quirk because it’s already been passed on to deku and the embers he was left with have been fully extinguished. The only reason she could restore lemillion’s because 1. He already had a quirk of his own and 2. The quirk deleter didn’t take away his power it just made his body unable to access it. All night can’t restore his OFA
MHA writers: that's a good idea *writes new chapter*
I've got a simple explanation here that you guys aren't going to like. Maybe JUST MAYBE Ujiko had to perform ACTUAL responsibilities as a doctor to keep his cover up for decades so he was just a regular doctor for Deku and Deku truly was just quirkless. As for reasons this 99.99% for sure the true reasoning,
1. Deku mentions nothing about "hey that was my doctor"
2. The doctor never mentions to anyone "hey that's the kid I took _____ from. He shouldn't have a quirk"
3. It most certainly is NOT Decay as timeline wise it doesn't work as Deku wasn't born yet
4. IF Deku had a quirk it would have been a combo of fire breathing and attraction and we've seen nothing even REMOTELY close to that description shown by anyone let alone AFO or Shigiraki
5. In grade school Deku does appear to be the only one who is quirkless which based on the statistics of quirkless individuals, checks out
6. In order to not raise suspicion, Ujiko could not take too many quirks as the % of quirkless individuals would rise drastically. That would cause an investigation, people would see his hospital had an unusually high number of quirkless diagnosis, that would then center the hospital as the focus of their investigation, thus eventually leading to Ujiko getting found out and ruining all of AFO's plans.
I'm sorry guys, as much as we love to theorize, Deku just WAS born quirkless and it's just fate, kismet, destiny, luck, happenstance, etc. that Ujiko was the doctor he saw. There's just too many logical fallacies to say Deku had a quirk and it was stolen which in turn would harm the story rather than enhance it.
One theory I like is that Deku developed the All For One quirk cause his father is AFO. It had to be taken to keep AFOs secret cause if a child was found to have the same quirk then it would give Allmight a lead as to AFOs identity.
Also if anyone says "but Dekus father has a fire quirk!" AFO might have only pretended to only have the fire breathing quirk around his wife.
I actually like the idea that the basis for Super Regeneration actually came from a quirk stolen from Deku. That would mean the nigh-inviinicbility Shiguraki, All For One and all the Nomu's have would've actually been engineered from Deku, ultimately making him one of the main causes for all of the Hero's suffering.
Would love that plot twist of Deku breaking down completely.
@@furanduron4926 real
Wouldn’t do anything for the story
His original quirk was a mix between Half hot Half cold, and decay. Since AFO knew it would drive Toya to the side of darkness he used the doctor to steal Deku’s original quirks and give it to Shoto when nobody in the totoroki house was aware, and since endeavor was already trying to create that quirk he didn’t notice. Deku’s dad already had a fire based quirk so it makes sense. AFO gave Deku’s remaining power to Shigaraki because he knew shigaraki couldn’t control it without the guidance of Nana Shimura who he still resented the legacy of
That's actually really cool. I can just imagine Deku clutching his chest and saying, "It's all... my fault?"
Guys there is one fact that throws that theory out of the window. In the beginning of the anime we are being told that all quirkless have 5 toes. And Izuku does have 5, so he couldn't own any quirk before OFA.
And who are you told by? The same doctor. You think there’s no significant plot point having one of the antagonist be the one to tell Deku this? I don’t think it’s decay but 100% Deku has a hidden quirk we don’t know about.
First of all it's not about the number of toes but joints in toes
@@Bori.1776 if he has a hidden quirk, then why hadn’t the vestiges mentioned it by now?
@@jacoba6747 he doesnt have a hidden if its stolen
Actually, it was one less joint in the smallest toe of each foot. Deku's mother could have proven this if he was lying because she was the one he was informing of the matter. As she is Quirked herself, she would have known the lie for what it was. I'm sure the joints don't change if a Quirk is stolen.
Now, the better counter of this theory: Deku and Shigaraki are at least 4 years apart in age. Izuku would still have been an infant by the time Shigaraki exhibited his Quirk.
if Dr. Ujiro didn't steal decay quirk from deku, he can never make friend
I think deku had a mixture between his moms quirk and his dads which is fire breathing so deku could just make people float close to him with the same quirk as his mom and then set them on fire with the fire breathing which this seems very OP
That same dr had grandson that was bully of deku (the one whit wings) and turn him into flying nomu from Stain arc
His real quirk is his rizz
Mann! Imagine…Plusaa Ultraaa!!! Rizzzaaaa!!!!
ONE FOR ALL…DETROIT RIZZ
"RIZZ FOR ALL! 1 MILLION PERCENT!!!"
I was today years old when I realized it was the same doctor to diagnose deku as quirkless that helped all for one
Decay can't have been izukus original Quirk since decay was an edited copy of Overhaul's Overhaul Quirk!
According to lore, there was someone [who I forgot the name of] who knew how to copy the Quirk factors using the original Quirk users' DNA and edit them.
AFO edited a copy of Overhaul and got rid of its ability to restore and reform matter, keeping only its destruction capabilities and was given to shigaraki!
I like the theory that Deku did have a quirk and it was stolen from him, making him an empty vessel for One for All, and I also like the theory that Deku's quirk was Decay.
A big issue with the Decay theory though is that if that is indeed the case, the time frame is extremely slim for it to be stolen and then transplanted to Shigaraki, as he is at least 4 to 5 years older than Deku. This means that it would have to have happened when Deku was a newborn for the timeline to make any sense and there is a possibility that time frame is just too slim for it to even be a possibility.
The reason why I like the Decay theory however, is that it makes some kind of sense considering his parents' quirks. His father can apparently breath fire and his mother can attract small objects to her. Fire is a chemical reaction that breaks larger components into smaller, usually more simpler components, while the attraction quirk's specifics are unknown (telekinesis, gravity, magnetism, etc.) it can make sense that added to the fire quirk it acts as the vector for the break down of things touched without the actual chemical reaction (replacing the fire with whatever force is used)... or maybe there is a chemical reaction but its so efficient there is little to no heat waste in the effect.
The time frame simply shows this theory is impossible.
technically shigaraki was born with decay
@@JavierGarcia-gd3yv It's highly unlikely, besides, the writing is on the wall, All for One literally was with him the day Decay awakened.
I like to think Dekus original quirk would be fire immunity- it would be difficult to detect early on, causing them to seek out quirk counselling. It’s easy to remove with nobody noticing, and AFO would’ve been on the lookout for quirks to counteract the top few heroes either after or preparing for his fight with all might depending on the timeline
also as far as we know bakugou didn’t burn him even by accident before he went to the doctor, and they were friends until that happened so he would’ve had his quirk and would’ve had the least amount of practice/control with it
yours is an interesting take on the definition of fire tho i like it
wow. ya'll crack'd my back from ALL that REACHING.
On multiple occasions, they stressed that a body has to be made to handle its quirks. Shigaraki in particular was showing signs of quirk incapability in the first few seasons by constantly scratching his arms. I think a twist will come down where Shigaraki will succeed in using decay on Deku and it won't work because Deku was the original user. It will also turn Shigaraki against AFO, for when Shigaraki realizes that he was not born with Decay he will know it was AFO that killed his family.
The fact that quicks come at a early age and kids know they have powerful powers is crazy to me because if they wanted to they could destroy the whole house
This can’t be true. The doctor literally said that people with quirks have 2 bones in their pinky toe, and Deku had 3, meaning he was born quirkless
YES!!! Thank you!!! I’m commenting “What about the bone structure of his pinky toe? 👀” under every comment not related to this 😂 I have no idea how it’s being overlooked by SO many fans of the show
You're talking about the same doctor who hid his identity and stole quirks for the biggest bad around? lol not a great source for reliable and trustworthy info. He would have to tell parents *something* about why their kid doesn't have a quirk after he's stolen it. Could have made up the theory, used his long life to propagate it - or if the bone thing is real, he could just show them a fake x-ray.
What if he fake the x-ray then
How many doctors did Deku’s mom follow up with though? It could easily have been faked with the number of quirks AFO and the doctor had piled up.
Nothing this doctor says should be trusted.
His real quirk was expand d•ng. Ujiko stole it, but it was useless.
What about the bone structure of his pinky toe? 👀
Deku seriously needs some self healing quirk
This theory is grasping at microscopic threads for it to make sense 💀
If this is true, I think the combination of his parents' quirks (telekinesis and fire breath) would be the ability to manipulate fire like a Water Bender manipulates water.
Remote controlled fireballs, fire shields and walls, nullifying Endeavor, Dabi, Bakugo and half of Shoto...that quirk would be *devastating*
But don't quirks usually mix? his quirk would have been fire breathing and pulling stuff, maybe he could fire bend idk.
Quirks mutate too look at eri her parents apparently didn't have a quirk similar to hers
I mean the mom uses her hands and the dad burns stuff?? A mutated version would be decay
Fire bend with his tongue
Nah... Deku got extra joint in his pinky foot finger. That's a mutant quirk he has
Dekus foot says otherwise
Correct me if I'm wrong but isn't Shigaraki like 20 something while deku is 16? That means the age difference wouldn't like up for Deku's quirk to be decay. I think it is possible that Deku's quirk was powerful tho. His mother has telekinesis, it may be weak and only work on small objects but what if his father also had a tk based ability? We know hair colors and shapes have a relativity to the users quirk and to be frank, not only is Deku's hair VERY green but it's also wavy, unlike his mother's. With a little bit of assumption, we can gander that his father may have had an AOE TK ability (since his wavy hair could suggest "waves" of TK) that could be limited by something like mass. Combining that with his mother we could get something like a stronger, faster acting force that could grab several objects from around him under a certain weight or mass scale. If we consider that, we essentially have a telekinetic force field that could be buffed by AFO's other quirks and it would also be extremely effective against just about anything since it's mass based on not necessarily force based. The only question that remains is where that ability would be now and since we don't see it in the story my theory is practically null and void.
His father had a green flame like quirk or fire breathing I think, his hair is likely green flames(the waviness) which may be dark from lack of his quirk
@@logansl4008judging off of that its possible he'd have got pyrokinesis
Orrrrr he was born quirkless
@@torbjornenjoyer which is possible and why AFO/the doctor may have wanted the quirk
@@tyctonic5936 also very very possible
This might explain why Deku and Tenko have such a strong connection. Additionally, it may explain why we’ve never seen Demi’s dad and his mom shows easy signs of someone after being left suddenly by a significant other. The weight gain, extra cling, denial even to the point of psychological blockage in the form of amnesia.
First off, Shigaraki's an adult and Deku is a teen. Since Shigaraki's quirk manifested at the age of 5, Deku wasn't even born at the time. Deku's dad works overseas and provides for the family. And Deku's mom got fat because of the depression over Deku not having a Quirk. Also, the doctor can only cultivate quirks for a long time, and is immortal, but he doesn't have the ability to steal quirks
AFO causing his own downfall by the hoist of his own petard? Sounds about right.
imagine, Deku the one that always give you a hand to stand up, with the power to destroy you with his hands..
Mother quirk-attract things
Father quirk-breath hot fire

🤣🤣I like this one
💀
He explains that the quirkless have a missing joint in the pinky toe, which Deku has. Also Ujiko never had the power to steal quirks, he just has immortality, and can cultivate quirks over a long period of time using his lab. He wouldn't have any possible way to stea Izuku's quirk.
Thinking on the whole Missing joint thing, why is that never brought up again? I would find it highly unlikely that Deku never needed to get an x-ray after everything he did. Especially since he breaks his bones so frequently. I can see them trying to get Recovery Girl to do most of the checkups, but what about when that isn't possible? The movies for example, where Recovery Girl isn't nearby.
@@corruptsolstice340 While that is a concern... Doctor patient confidentiality is a thing. It may be a thing said off screen, but it's not like they'd tell anyone else unless absolutely necessary. Other than that, there's not that much of a point to bring it up.

This should be a good plot twist In my opinion.
You see this would be an awesome theory,and the only thing Horikoshi had to do if he ever had to use it at the start of the series was just drop a line somewhere saying that “20% of humans don’t have Quirks,and a good 8%-10% of that 20%, live mostly in Japan” like the fact that Japan would have been the country to have the majority or a “higher” percentage of Quirkless people would have made of lot of sense.
I mean the number is high enough that, if your Quirkless you would think more people like you are in the country, but don’t forget that Quirkless people self-termination might go down which would be a plus.
And the Quirked population would complain less I mean Quirk bias would still be their, but maybe just a bit less.

What. Did you even read or watch MHA? He got one for all from that you idiot
Bro turned into Dr. Ujiko for a sec there
This makes complete sense (apart from the decay part) I always thought the doctor was just some random dude. Didn't realize it was ujiko so it's a big possibility he did something nefarious
In a theoretical way this could make sense due to the fire breathing quirk inherits spread damage and telekinesis affects movement. In a molecular scale, decay is the release of energy from tearing cells, tearing apart order into chaos. May not be real but it's a fun mind theory. In my opinion, with the singularity theory and how people tend to inherit quirks from family, decay is a wierd quirk for a kid whose parents have no predators for a quirk such as it.
Mum: attracting small objects
Dad: breathing fire
Midoria: attracting hot things
(Cue happy accident scenes)
A theory that doesn't have a single leg to stand on or a shred of supporting evidence, yet is somehow "popular"
This theory completely throws the one for all singularity and quirk plot.
Also how the hell would Ujiko know what quirk Deku had, he didn't have search, quirks like decay which is a mutant are still like normal emitter quirks and wouldn't have any tells.
And Deku would've remembered if he touched something and it crumbled Infront of him, especially doctor Ujiko
Not only that shigaraki was 5 when he killed his family while deku was either still in the womb pr barely a year old
I mean CRISPR and stuff exists in real life and its not too far fetched to think that he can have a way to look at genes bc quirks are just mutated genes
@@akshayraju4610 CRISPRR is still in testing, and quirk cells aren't just mutated cells. The vestiges of OFA literally said that Deku was quirkless which let him cultivate OFA to its fullest potential in the Class A vs Tomura arc.
And because when bodies evolve, they discard of organs, bones and more that aren't needed, like the second joint in the pinky toe. literally the first damn episode said this
It's possible that the doctor just stealed random baby quirks and tested them. AfO could always just confirm each quirk for himself so there was no need to wait for the quirk's awakening.
The timeline barely fits. And there was clearly some point in him being Deku's doctor. I doubt it was just to show how even an innocent looking person can be so evil. The mangaka definitely has something planned about that.
I mean, the author had us believed
that tokoyami spend 15 years of his life without realizing that he could fly with his quirk. He is definitely the type of writer that makes up stuff about earlier parts of the story without foreshadowing as long as they don't contradict with anything established.

Decay, Deku,
Huh. Kinda easy on the tongue, dont'cha think?
Although the decay thing would be cool as well as this theory I think his quirk would most likely be something a lot weaker like his moms quirk (attracting small objects to her) or his dads which I believe is fire breathing (which is pretty cool) i could also imagine it could be some fire attraction quirk or some sort of mix. 🤷🏻♀️

Interesting, but it's not likely he had decay given quirks are related to 2 things; personality & hereditary mental history. Deku's mom has water based abilities much like his explosive childhood friend has a bombshell of a mom. This is also a tragic concept as well given OFA accelerates your life span & if he had one prior it's possible he will die. Also, antigravity + thrust could be the source of decay; pushing atoms apart like smart atoms from Invicible.

His quirk being stolen is actually really plausible. The quirk itself being decay is a little less likely but at the same time it would fit the narrative really well. I wouldn’t be surprised because MHA has some pretty solid writing and a lot of people overlook that
I JUST REALIZED THAT DOC TOLD IZUKU

deku is 0-1 when his quirk gets stolen. Shigaraki is given the quirk by all for one to kill his family, that's why it went out of control after all for one brings him back home. It also explains shigaraki's constant scratching because the quirk was rejecting his body, because it wasn't his.

It makes sense, shigaraki's body clearly is rejecting decay. We don't see too many other individuals with native quirks that do damage or have a backlash
And how old do you think Deku was when Shigaraki was 5?
Shigaraki just evolved to be able to use decay better, I believe he can’t take all the quirks that came from all for one
Shiggys body WAS rejecting decay. It stopped. Then his body started to reject AFO, once it was given to him
@christophercardoza2872 No, so think about it, the dry skin, the need to itch . Feeling gross constantly. His body was not compatible with decay at all. Theoretically, they could have taken the deku's quirk at any point, not just when it would have manifested.
@Clayton Talesfore or decay is why he's always itching. Not that they aren't compatible. He's always nervous and the quirk itself can cause the itch because it's decay
Combining his parents quirks deku would likely have something like a remote ignition quirk that would allow him to start fires with his mind
From what I’ve heard his parents don’t have quirks related to decay, his father had a fire ability and his mother telekinesis I think.
Thier ages don’t match up. Deku is 15-16 shigaraki is 21
They do though? Shigaraki is 21 which means when he was 5 deku should have just been born or would have been a baby, assuming he had his quirk at a young age like a few months old or just born(you can have a quirk at birth, any age under 4 can develop a quirk) he could have had it stolen. It lines up perfectly. If he had his quirk stolen as a baby it would line up with when Shigaraki gets his quirk and explains why Ujiko decided to be his doctor and lie about his quirk. His explanation about the toe joint is just bs he made up to tell parents of quirks he stole.
@@Williamwillow_ Still doesn't add up because All for one doesn't know about Izuku nor Inko
@@detectivesmokeguy1672 Why would he? If Ujiko is collecting quirks from hundreds of kids because of his job as doctor how would he know every single kid and parent?
@@Williamwillow_ Does Ujiko have the ability to steal quirks? I’m pretty sure AFO needs to be the one to do it.
@@Williamwillow_still wouldn’t make sense. Shiggy wasn’t give his quirk. If he was then AFO would be the one who’d have to have given it to him. If that’s the case his initial dialogue wouldn’t make sense
It's possible. Maybe it's the reason why he has a connection with shigaraki. Why their fates intertwined.
Then a major twist in the end where Deku is actually immune to decay being he is the original owner of it and by God's grace, saves everyone with this asspull.
But to be honest, it's somewhat of a good foreshadowing of when shigaraki had his hands on his neck explaining how it works and all during that time.
Deku is 16, Shigaraki is 21. Shigaraki would’ve been 9 when Deku got his quirk stolen.
@TuxedoMask189 isn't it weird? Deku got bullied by bakugo at a young age and now that karma is back at bakugo by shigAFO and how futile it was to fight him with his quirk.
@@ky015 and ShigAFO wrecked him while being quirkless by aizawa.
It’s impossible because the toe thing you can’t have a quirk if your toe is a special way that’s easily identifiable
@julius white great point but as it says, it's "almost" always quirkless. So it's a small chance. Think of it as a Shonen jump type of a small chance.
Love this theory, it can even be expanded upon. Deku’s toe that was seen in the X-ray is prevalent bc only those with very special/powerful/rare quirks have this in common! I could go into meticulous detail but I have a word limit
You forget shigaraki was older than five when this happened
His quirk is actually all the friends he made along the way
