Izuku Midoriya (Deku) is autistic - HC
Hi hi ~ so I am autistic and I strongly headcanon most of BNHAâs characters as neurodiverse (and gay but thatâs another story). I think that Deku is definitely autistic and here are the main reasons why. For this âanalysisâ Iâve used both the anime (until s4 which is currently airing) and bits of the manga.
(Iâve had comments on my previous autistic headcanons pointing out that I was projecting myself onto the characters and YES I am very much doing this. No but seriously, I am writing about why I think certain characters have the same neurodivergence as me so yes of course Iâm going to use my own life as a reference and as a material to explain why I think the way I do. If it bothers you itâs fine but donât spread negativity is all I ask for.)
All autistics are welcomed to add to this post btw Iâd love to have more perspectives <3
1. Stimming
I feel like this one is extremely obvious so Iâll start with it: Deku is one stimmy boi omg. Just look at the way he swings on his chair before watching that one All Might video:
âStimmingâ also known as âself regulatory behaviourâ is basically the repetition of movements, sounds, visual stimulation. Itâs a way for autistic people to calm and reassure themselves, concentrate and express their feelings.
Iâm also putting his mumbling in here because itâs very common for autistics to talk to themselves, itâs a form of vocal stimming:
2. Special interest
âspecial interestâ is a term used by autistic people to refer to the topics that interest them. When weâre invested in something itâs not just a hobby. For us it becomes an obsession, we think about it 24/7 thus why we have a word for it. A special interest is not only an obsession, itâs a safe place, an escape route if the reality becomes overwhelming, something that gives us a joy and fulfilment.
All Might and generally Heroes are Dekuâs special interest. He spent years to research and gather all informations in books. Heâs so obsessed he goes back into âfanboy modeâ super fast and forgets the time and place at times. He knows everything by heart AND well enough to use it directly in battles.
Also like his mumbling could be due to him being in hyperfocus: an intense form of mental concentration that focuses consciousness on a subject, topic, or task. Hyperfocusing on special interests is something quite common for autistics. Heâs so focused that he forgets that itâs not really âappropriateâ (by societyâs standards) to do that when other people are around.
AND he does that quite a bit huh.
3. Blunt, honest and infodumping
Deku is very honest and isnât afraid of being vulnerable. This is something I tend to observe with the autistic community because we simply donât see why some things are considered shameful or embarrassing. We say what we think and we donât see the wrong in that.
He has a tendency to infodump: Infodumping is the practice, common amongst autistic people, of giving intricately detailed summaries of their topic of interest in single heaps. This can occur in conversation both online and offline. âSpeaking in paragraphsâ is another way to describe this. It happens multiple times in the manga but this one is my favorite example:
First of all, he was SO stressed at the beginning of the interview. Again, this is interesting in itself because Deku is not shy, heâs usually more on the spontaneous side. It reminds me of when he had to be funny with Sir Nighteye to gain his approval because he was surprisingly very stiff. This makes me think that maybe he feels uncomfortable in any social situation heâs not already familiar with. Thatâs⌠Very relatable as an autistic person because most of us also have social anxiety.
Anyway, about the infodumping. This example perfectly shows the switch that occurs in his behaviour before and after a special interest is brought up. When being asked about himself he doesnât know what to say at all but he gets loud the moment heâs asked about All Might and start literally speaking in paragraphs. When can clearly see that heâs not stiff anymore. Talking about All Might was both a relief and something that got him suddenly excited.
4. Bullied
I find it so interesting that the series begins with Dekuâs perspective and within the first pages we are already introduced to the concept of inequality in this world. People are not born equal. Deku learns it very early at age 4 because heâs quirkless and I canât help but draw a parallel with neurodiversity.Â
Heâs bullied for being different, for not having a capacity that others have, for not meeting expectationsâŚ. This reminds me of almost every autistic person ever unless they become very good at masking (hiding autistic traits) very fast. Also he points out a few times that heâs probably not only bullied for not having a quirk. This makes me think that even if he had one he would have been ostracised anyway. Maybe being quirkless drew attention on him but he was different from the start. As an autistic person I relate so much to this and I think the discrimination he faces is very relatable to a lot of neurodiverse folks. This is my interpretation of this aspect of Deku.
5. Strong sense of justice
No Iâm not saying that us autistics are better people BUT I think we have a strong sense of justice that we arenât afraid to show no matter the circumstances. A lot of people donât express when the feel like something is unfair mostly because of social rules but because weâre quite blind to these we often blur out things without even thinking or considering time and place. I think we see that in Dekuâs childhood especially when he stands up for his beliefs while being quirkless and powerless.
6. He comes up with unique ways
Something very interesting with deku is how he always manage to come up with a unique plan. I think this is something most autistic people relate with because we often perceive things a bit differently than most and as a result we have unique ways to achieve our goals.
Ok and thatâs all for me ~
Honestly there is not one single moment of him that makes me think heâs not on the autism spectrum lol. I could understand people disagreeing with other headcanons but this one?
Iâve seen posts talking about hyper empathy as an autistic trait Deku has and I didnât put it in here because I donât feel knowledgeable enough on the subject to touch it. That being said I think itâs a very interesting point to make!Â
Anyway if youâre still here, thanks for reading I hope it was enjoyable!
