DEKU'S REAL QUIRK WAS STOLEN!!

What if Deku was actually born with a quirk, but it was secretly stolen by Dr. Ujiko?

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.

[@VariedPortrait]

Rizz quirk XD

[@LDIndustries]

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.

[@nurulafiqah4903]

​​@@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.

[@sailorpickles]

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.

[@CClaxer]

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.

[@user-ud6fk3ex6y]

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.

[@IDK-km7vd]

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

[@rafaelsoto4742]

[@bluesapphire4262]

​@@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.

[@ventusargentum9957]

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

[@laplace7943]

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.

[@jimimonsta3209]

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.

No.1 The doctor works for all for one.

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

[@GamerGabe876]

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.

[@YukiA816]

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

[@GamerGabe876]

@@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.

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…

[@Williamwillow_]

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.

[@sammyjaohnson5631]

Aint Shigaraki much older then deku anyway

[@AirForcePararescuer]

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.

[@rain4ru]

I think people are forgetting shigarski is way older than deku

[@aaronball4700]

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.

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.

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.

[@LE3MZ]

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.

[@derpfluidvariant0916]

This one is pretty fair.

[@CastleOfAvalon]

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.

[@CastleOfAvalon]

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.

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.

[@net_spider]

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'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.

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.

[@ziggerotstask6287]

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.

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.

[@brandonleecross468]

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.

Rizzuku Himdoria would be his hero name if he had his quirk, the RIZZ quirk

[@brenskullskull5282]

The only counter to this I can come up with is this: quirks always retain the bodily appearance of the original owner. Known as the quirk factor or the appearances of the previous owners of one for all. Since we can confirm after shigaraki’s battle with new order that none of his quirk factors were deku it’s impossible for shigaraki to have a quirk of deku’s

[@axelmexworld6122]

Maybe he got pyrokinesis with telekinesis in omega level but then got stolen by the doctor and give it to AFO

[@houseofbehr9983]

His quirk is actually all the friends he made along the way

[@claytontalesfore7564]

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

[@matt-thorn]

And how old do you think Deku was when Shigaraki was 5?

[@christophercardoza2872]

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

[@sheevpalpatine6139]

Shiggys body WAS rejecting decay. It stopped. Then his body started to reject AFO, once it was given to him

[@claytontalesfore7564]

@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.

[@tyctonic5936]

​@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

[@ameliarose5618]

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

[@enruzky]

Decay, Deku, Huh. Kinda easy on the tongue, dont'cha think?
