Even though Izuku Midoriya is considered an abnormal boy in MHA’s logic, he is just your average neighborhood child who strives to save people.
Given his body structure, diving straight in to save people is as close as attempting suicide. Deku can’t help but listen to his instincts to be the hero.
There have been several theories about Deku’s powers, and nothing is canon so far. Some actually think his abilities are hidden or stolen, so what exactly are Deku’s powers? Does he have a quirk?
At the beginning of the series, a doctor diagnoses Izuku Midoriya as quirkless. However, the doctor looks like Garaki from the villain league, the secret mastermind behind all Nomus.
They may be connected, and the doctor probably stole Izuku’s biological quirk for Garaki and All For One.
Note: This article will further discuss fan theories on Deku’s quirks. So, it is entirely based on speculations.
1. Was Izuku’s Biological Quirk Stolen?
Out of all the fan theories, this theory is one of the striking ones. Some fans suggest that the doctor, a.k.a Dr. Tsubasa, whom we met in the first episode of MHA, stole Deku’s quirk as it was comparatively more powerful and provided an advantage to All For One.
This theory has the potential to become canon. Fans started suspecting the doctor due to the similarities of his appearance to the mad scientist who created Nomu.
Remember that kid with red wings who used to bully Deku? He is Dr. Tsubasa’s grandchild. It is implied that the winged Nomu is that kid.
There are too many coincidences that point out that Dr. Tsubasa and Garaki are related. Maybe they look like each other because Garaki is his father?
They cannot possibly be siblings as Garaki is 120+ old. If they are related, he can be the thief who stole Deku’s quirk.
With All For One’s quirk, he would steal his patient’s powerful quirks and inject them into Nomu. It would ultimately make the patients quirkless, and he can use the excuse of their injuries and accidents for their current quirkless condition.
The original theory suggested that Deku’s quirk was stolen and given to Tomura; however, it does not match the show’s timeline as Tomura is way older than Deku.
Hence this part of the theory does not work, but it also doesn’t deny the possibility of Deku’s quirk being stolen.
We cannot say that the association of having an extra joint in the foot’s pinky finger is universally related to being quirkless; maybe Deku was an exception to this condition. Also, the doctor might be lying, or he may have forged Deku’s X-ray.
And it absolutely doesn’t make sense for Deku to be born quirkless as both his parents have their specific quirks. A child is likely to be quirkless if one of their parents is quirkless, but it is completely the opposite in Deku’s case.
There is a follow-up theory that hints Deku’s mum was a part of this scam. It explains her apologetic behavior towards her child.
As the canon theory of Quirk Singularity mentions, humans evolved into a superior species, which is way more overpowered than the previous generation.
The increasing power will one day become too much to handle for a human body. Deku is a part of the 4th generation, so what if his original powers were too much to handle, so Deku’s mother took part in this scam to save him?
2. Does Deku Have a Secret Quirk?
There are many fan theories on the internet about Deku and his quirks, one of them being Deku having a secret quirk.
Miracles only exist in Fantasy and Shounen anime, and My Hero Academia is a combination of them both. Deku is the show’s protagonist, and that itself gives him the power to change fate.
You never know what card he might pull. If one day Deku discovers his hidden dormant quirk, it would be really cool and would probably come in handy against Tomura at the end fight.
If at all it happens, I wouldn’t be surprised as Deku holds the Main Character tag, but it’s time for a reality check. Deku cannot possibly have a hidden quirk because he is quirkless.
He represents the quirkless faction for a reason. Horikoshi plans to give his audience moral dilemmas with the concepts of heroism, right and wrong.
The story is about the underdog Deku, who struggles, bleeds, and gets his body almost destroyed from constant bone smashing in an effort to be the hero. In contrast, Tomura was destroyed mentally and emotionally due to his quirk and his family circumstances.
Deku’s narrative of being an underdog will backfire on him if he discovers a hidden quirk. It wouldn’t make sense to suddenly give him a hidden power as it will be a major plot hole.
Unless it is justified with a good reason giving him a secret skill will be a gamble for Horikoshi. The secret hidden quirk theory is not valid in this aspect.
Even if he were to have a secret quirk, it would be similar to his parents, but they would be redundant since we have heroes with quirks of fire emission and telekinesis. According to the Quirk Singularity theory, Deku’s quirk would be more powerful than his parents, and hence it would be difficult to unsee.
However, what if his hidden quirk came with a prerequisite condition like All For One’s brother? It would explain why he hasn’t discovered the quirk yet as he has not met the required conditions.
For instance, a quirk that can revive him after death from natural causes or a life force quirk that can extend his life after being in a near-death situation.
Some fans believe his quirk is an advanced form of telekinesis that lets him heal faster than others. Thus every time he gets injured from using One For All, he subconsciously heals himself.
There is also a crazy theory that implies All For One is Deku’s father, and it just blows my mind.
It leads everything into circles. What if the persona Hisashi Midoriya never existed? All For One’s quirk allows him to steal other people’s quirk and transfer them.
He was practically the reason for the origin of One For All, and if Deku inherited a mind quirk like him that lets him use quirks to their maximum power or something along the lines, it would make sense why he can use the quirks stored in One For All and see the vestiges and why he is so obsessed with quirks.
3. Why Didn’t All Might Use The Other Quirks?
Since it was All Might who transferred One For All to Deku, it should have been obvious for him to use the rest of its stored powers; however, he doesn’t seem to have any clue about its existence.
Not only he had no clue about it, but he has never experienced visions as Deku does. If we leave the mad conspiracy theory of All For One being Deku’s absent Dad aside, it leads to the question of why Deku is the only one to use the stored powers?
All Might has started researching these hidden quirks inside One For All. His research somehow connected him to the other users’ consciousness inside One For All’s made-up universe. Here are some theories on why All Might never use the other quirks
One For All is a very powerful ability, and most of its wielders passed away young. All Might’s master, Nana, died before she could explain anything to him.
His fighting technique is different from Deku’s as he primarily relies on brute force. He didn’t need to plan out strategies like Deku because he could fully manage the strength that comes for One For All, unlike Deku.
Like the Transfer quirk of All For One’s brother, certain conditions had to be met to unlock these stored quirks.
Only Deku could unlock it due to his potential hidden quirk, or it can also be due to his fanboy habit of overanalyzing things created the chance to meet the conditions to unlock it.
The core wasn’t fully developed. Consequently, All Might couldn’t use the other quirks. This theory also suggests that other users couldn’t bring out all the previous stored quirks as well.
It actually makes sense because One For All develops more with the next transfer, so Deku is in the perfect condition to make use of it.
Deku is probably the last user for One For All as it has become hard to handle, and quirkless people are becoming almost extinct. If it is shared with a user that already has a quirk, One For All will totally damage their body.
If any of these theories prove to be true later on, My Hero Academia will surely take an exciting but dark turn. Especially the theory about Deku’s dad is really dark. Let’s just agree; Hisashi is the most suspicious character throughout the history of MHA.
