Why isn't Izuku dead? A Discussion on OFA + Secondary Quirk Characteristics

This is something I've wondered ever since the reveal that Hikage Shinomori died from old age at 40, because of the strain from having 2 quirks. The obvious explanation is that a human being cannot possess more than one quirk (unless you're All for One), because they will experience "quirk overload", where the mind (think like in the Nomus) and body (think like in Nine) cannot handle the quirk. This is the reason why only a formerly quirkless person can safely wield One for All.

But there's something missing here.

Izuku is shown to be the only user of One for All to be able to use past user's quirks. All past vestiges had only been able to use their original quirks and the power-stockholding aspect of One for All, even All Might. One For All has also been confirmed to have reached quirk singularity, which only makes the situation more confusing.

There are other people who have been in possession of multiple quirks without becoming Nomus, such as:

All for One

Gigantomachia

Nine

Number 6 (antagonist from My Hero Academia: Vigilantes)

Tomura Shigaraki

Izuku Midoriya

However, Nine, Number 6, and Shigaraki all underwent severe body modification to be able to handle the quirks. Healing quirks, such as Gigantomachia's Endurance, Tomura's Super Regeneration, and Nine's attempt to claim Cell Activation, are also able to undermine the effects of quirk overload. This leaves us with only two "natural" multiple quirks holders:

All for One

Gigantomachia

Nine

Number 6

Tomura Shigaraki

Izuku Midoriya

Izuku's capability to hold multiple quirks can't be attributed to his prior quirklessness, since he now has no less than seven quirks. Born without a quirk or not, that's still being in possession of more than one. By all accounts, Izuku should be braindead, or at the least, aging extremely fast/being in bad health, but he isn't.

Now, let's have a quick talk about Secondary Quirk Characteristics:

What are they? These are quirk characteristics that are inherited by a person even though they may be unrelated to their own quirk.

Fumikage Tokoyami - bird head that is unrelated to Dark Shadow

Koji Koda - rock-like head that has nothing to do with Anivoice

Mina Ashido - horns, eyes, and skin that are not part of Acid

These are usually traits that belonged to a person's ancestors as part of that ancestor's quirk. Sometimes, these traits will compile with others to form a combined quirk (such as Tsuyu Asui's Frog quirk or Shouto Todoroki's tolerance to fire and ice with his Half-Cold Half-Hot).

Secondary Quirk Characteristics can actually be compared to Darwin's Theory of Evolution by Natural Selection. If the trait aids/does not hinder the body's ability to safely use their quirk (and by extension, to survive), then it will be passed on. There is even speculation that the designs of the cast are due to these secondary traits (like the Midoriya's green hair), making them much more colourful than their Pre-Quirk counterparts. This would mean that secondary traits can be inherited by someone regardless of if they are quirkless or not.

How does this relate to Izuku's strange ability to use multiple quirks?

Because of the theory that he is related to All for One (more specifically, the Dad for One Theory).

His ability for holding many quirks can be logically explained by two things:

He could possess a secret quirk that is a fusion between the All for One quirk and Inko's Attraction of Small Objects quirk. If so, the quirk might not express the same holes as in the palms of All for One and Shigaraki, since Izuku could theoretically "pull" quirks towards himself, or it could be another type of AFO-esque power (can gain quirks though DNA-consumption, can pass on quirks like Yoichi, etc). Whatever it could be, it would have to be something that can provide him with the protection from quirk overload. Even AFO might not know about his quirk, since he wasn't able to detect Yoichi's original Transference quirk. This suggests that All for One can't detect quirks that can actually manipulate the DNA of other quirks (unlike Aizawa's Erasure or Monoma's Copy, which just block/copy their effects), or that he cannot detect quirks that are in held by a family member. I don't really which of those it could be, since canon never really explained why Yoichi's original quirk was noticed.

OR

If he is truly quirkless like the series says, he could have inherited a Secondary Quirk Characteristic that allowed him the capacity to possess multiple quirks, even if he was quirkless on his own, making him the perfect vessel for OFA. Plus, it completes the family trio.

All for One - Takes/Gives Quirks

Yoichi - Passes On Quirks

Izuku - Keeps Quirks

It's a silly little headcanon with the singular piece of evidence going for it being literally only that Izuku's father has a fire quirk.

It's just hilarious to me.

There is so much potential for drama and comedy; just the irony that Enji indeed created the perfect successor that would finally surpass All Might...except it's not the child he thought it would be and it wasn't even due to his own merit. *chef's kiss*

AFO gets younger with each chapter and I still believe that the Star Wars nerd that is Horikoshi will give us a “Izuku, I am your father” scene, but if things keep going this way it’s gonna be a baby dropping that bomb.

Dad for one fic rec!

Urges by Gentrychild

summary: Izuku has all for one quirk, his life is spent dealing with quirk discrimination and being feared and unwanted by his own mother, until he snaps. Very slight dad for one with them only meeting at the very end and is mostly a revenge fic but it's good

Characters/Pairings:Izuku Midoriya/shoto Todoroki

Summary: Izuku wakes up in the recent light novel he read called “ My Hero Academia.” Unfortunately, he’s in the body of Midoriya Izuku, a minor character killed off early in the manga to motivate the main character Katsuki Bakugo on his Hero’s Journey. Izuku decides he’s going to do whatever it takes to stay alive in this stupidly deadly Isekai.

Unfortunately, Izuku isn't aware that in the last novel of the series where the minor character who died is revealed as the main villain’s son.

All for One has relived his son’s death multiple times, unable to change the outcomes.

But something has changed this time

Midoriya Izuku has All For One | Dad For One | Parental All For One | AFO is Midoriya Hisashi | Dead Midoriya Inko | HeroStudent! Midoriya Izuku | Shenanigans | Ongoing

All For UA by ScottishSunshine

Izuku Midoriya is going to be a hero, and where can he learn that better than U.A.?

Sure it'll be challenging, but he has the full support of his rather... unusual family, and he'll be attending alongside his closest friends!

And besides, All For One retired years ago and has made it quite clear he will not be returning to his life of crime so long as Izuku keeps him supplied with hugs.

With the most dangerous villain ever officially dead, what's the worst that can happen?

Guys, last night I had the weirdest dream that I was All for One and was getting married to Inko Midoriya, which was terrible because:

her mom (Nana Shimura) was being a monster mother-in-law to me (fair enough)

All Might was there in a really bad civilian disguise that somehow fooled everyone

and he couldn't fight me because he thought I was going to kill everyone there

the wedding photos went really badly because they couldn't fit me in the shot (being 7'4" is a real pain)

I think at some point Mitsuki Bakugou socked me in the face (also fair)

I kept banging my head onto doorways

the real All for One is freaking out in my head because he's stuck there

I wasn't sure whether to laugh, cry, or die because while this is amazing and I'm sure AFO feels every bit of the pain I feel, so many people are being mean to me (again, fair, but ouch)

this man has, like, a thousand quirks, and I can't control any of them

I end up crying over a glass of sweet tea

So, anyone want me to write this??

[maripolifan]

If MHA was just a little sillier...

The biggest question left in the series unanswered (so far)... 

Who is Hisashi Midoriya? Who IS Izuku's father????

Ik I'm playing Russian roulette rn with how things are going in the manga lmao

Note:

Endeavor is here because Izuku being his secret love child is an actually funny theory (to me)

All Might is here because he's def hitting that

AFO thinks he's the top dog, but he is, at most, a clown

Mystery guy. Ignore him. Maybe he got lost on his way to the restroom?

Why All for One is Izuku’s Father pt. 9 — Izuku is Foreshadowed to be the Next All for One

“Can the child do it, I wonder?” I’ll let him do all the work so that he can become the next “me”! That child was born warped enough to do so.

Dissect this phrase first: I’ll let him do all the work.

All for One implies that Izuku has chosen a path that is hardworking and thorny: “The path you’ve chosen is a thorny one. Every battle grinds away at your soul with no end in sight.”

All for One: I’ll let him do all the hard work so that he can become the next “me”!

All for One’s secret plan has always been to make Izuku into the next All for One. He’s next—or, in other words, it’s his turn.

“Corrupted” by @dookoa

Why All for One is Izuku’s Father — part 1

Part 1 – “Izuku Midoriya is All for One’s true successor (the next All for One)”

In chapter 59:

“Wonder if “the kid” can do it.” Or in some translations, “Can the child do it, I wonder?”

“That child was born warped enough to do so.”

Shigaraki is 20 years old, not a child/kid.

“I’ll let him do all the hard work so that he can become the next “me”!”

This popular technique is called a Red Herring. It means to redirect the audience’s attention onto a likely/popular topic in order to hide the true answer/truth. In this case, All for One’s hand over Shigaraki’s image and Shigaraki being All for One’s student is the Red Herring—to take our attention away from his intended target, Izuku Midoriya.

(Personal opinion: when All for One says “that child was born” it sounds like a dad would say that.) There are two roles with different people:

1. “Shigaraki Tomura, his position is to unify and supervise them!”

2. Can the child do it, I wonder? “I’ll let him do all the hard work so that he can become the next “me”!” That child was born warped enough to do so. — Izuku Midoriya

3. Can the child do it, I wonder? That child was born warped enough to do so.

It only my thoughts and interpretation. I just haven't seen such thing in bnha fd so I did it. It was fun!

[ernand-0]

Hori is just messing with us at this point

Here is something someone pointed out to me on the AFO discord. I don't know Japanese, so take things with a grain of salt to not spread misinformation! But. . . Koga - the construction company that AFO had/worked at.

How it's written in the Japanese version: 甲 - armour/first class 賀 - celebration.

Okay, nothing specific.

BUT... What other way can Koga be spelled as? 久我

AND GUESS WHAT THAT MEANS!

久- Hisashi 我 - I/myself (I am Hisashi) … Yea
