Why reincarnation quirks aren't very good, by AFO the Demon Lord

Summary:

All for one fucks up ever so slightly.

Naturally, this leads to him accidentally becoming a child, hero, his brother's successor, accidental saviour of Japan and almost decent person, not necessarily in that order

Or

AFO becomes Midoriya Izuku

Also, thanks for you guys from Fair and balanced incorporated because without your support this wouldn't exist

Notes:

This work is inspired by the seventh horcrux, hp fic where the big bad becomes the chosen one that's supposed to kill him.

On the same vein, I have made AFO less of a psychopath, more just a petty shit without morals, and with a lot of grudges.

Chapter Text

Hundred years ago

“And who are you and why have you searched for me?” said All for one, in a small cell of his evil lair. He was speaking to a young man that was caught sneaking around his base.

“I heard you can take abilities.”

“And what do you want with that?”

“Every time I die, I am born again. Reincarnated, if you will. But I don't want to.”

“Ah well, that can be easily fixed.” Laughed AFO and took the man's quirk.

Couple years ago (15 to be exact)

“Ahaa All Might, I have won. Do you now understand you stand no chance against me?”

“I… won't… loooose.”

‘Oh shit’

Today

“Midoriya has applied to UA too.”

Ah, so the teacher has once again chosen to attack me. Not that he has anything against me personally, but his Destroist beliefs and my sssecret quirk combine into not good. It's rather obvious he knows about me, after all, why would an entire school bully a child just based on quirklessness, he is just trying to get a rise out of me so he can set heroes on me. Not that they are a threat to me, but I rather like living like a civilian.

“Yes.” I say meekly, continuing our years long game of deception.

The brainwashed children join in, not having a clue that annoying me enough might lead to death (or just light torture, I am not a monster, I wait till they grow to eighteen at least) and continue the pathetic assault.

Ah well.

Finally the class ends. One of my at some point greatest assets is now annoying me for a change. I guess their brainwashing is really good. His pathetic nitroglycerin explosion damages my notebook for when I am bored, but it was already full so this setback doesn't matter at all. But i get more information about their methods of brainwashing everyday.

Truly, a work of art, that brainwashing I mean.

Anyways.

I leave, going nowhere in particular as I don't really have anything to do today. My chaotic direction choosing leads me to meet a new friend.

Quite unfortunately for both of us, that is me and the new friend I found, the new friend isn't really friendly. More of a nemesis of the week. Some might even call him a grey hero now, because of my employment and past clothing choices.

Some kind of slime, ugly green tide, so transformation quirk, jumps at me with ferocity only comparable to my brother's followers or better word might be cult members with how many there were.

But he is pathetically slow. I could kill him hundred times before he even noticed me.

But I, as an evil evil demon lord (I am a human, I need a hobby) let him believe he won, getting ready to brilliantly outplay him.

But a hero appeared. Annoying. I let myself be thrown back by an air blast, and instantly get knocked out.

….

“Wake up young man.”

Ah so another one of my nightmares where I lay broken before that oaf?

“Ah good you woken up.”

Wait that's actually him.

He tries to jump away. Naturally, in my half conscious state I grab at him. Naturally I didn't have any movement negating quirks so I fly away with him.

Not good.

I can't let go because I would either die permanently or have to be a child again. Not good.

So I need to trick him. Or just keep up with my Izuku Midoriya persona.

Well, we landed. I need to think fast. I am a fan so I need to ask a question. What's your weakness? No no no. How do you feel when you don't manage to save someone and they die before your eyes? Maybe. Ah I got it.

“Can I be a hero even if I am quirkless?”

Naturally he will answer yes, he too wanted to be hero as a quirkless child.

“No, I don't believe you can.”

I ignore rest of the taunting as I realize with terror that All Might too is a Destroist. All his decisions make sense now. His voting, his manager's investments, his meeting at Deterant, his morning cereals.

So he knows who I am.

That slime was all just a trap, so that he could reveal me, but he messed up his timing.

A plan on my level.

And if he is from MLA, there is noone to stop them, if we account some other heroes who are deep undercover.

So I decide to do something very important.

I will save Japan.

Because I could lose.

But Destro will never win. Not even if the whole world turned upside down.

Not after he moved the chair from under me at the super secret super villain meeting of super conquering the world.

Of course this plan has to be postponed. Because I ran into the slime again. I didn't really do it willingly. I was just deep in thought, thinking about my supersecret and superevil plans. And suddenly I am in front of him.

But of course I first saw my stolen asset, Bakugou was his name, and naturally, he was screaming and looked like he was going to attack me so I threw my backpack at him.

Only then I realized he was actually submerged in a green slime.

Well, heroes took it as me trying to help him, so that's good.

But all time, my saviour was staring at me. All Might that is.

Shortly after I left the scene he jumped me. Well, if he wants a rematch, this day will at least be interesting.

“I would like you to become my successor.”

Ah yes the talk about successors and all that standard torch thing and how my time has come…. Wait a minute what?

“Can you repeat that?”

So he talks about all that torch shit now, and how he can pass his quirk on me.

Meanwhile I scheme.

What is his goal now?

Maybe he is forced to work with MLA through some sort of extreme blackmail so he saw me, took it that I redeemed myself enough and decided to return the quirk to me.

Well, this will be fun at least.

“I accept.” I finally say.

All Might is happy about that.

Cut

Ah, but my nemesis didn't just give me the quirk. Of course first he had to torture me for eight months. His insane training regiment was well, insane. American dream plan my ass. I barely survived it. It was the worst thing that happened to me since I was born.

Then I got to eat a hair. Make the training second worst thing that happened to me.

Where did normal people with blood transfer go? My brother started the tradition, but apparently it didn't continue for long. How disappointing.

Also, we didn't talk about me being me. If he doesn't wanna talk about that, neither will I.

Welp.

Cut

Now I am probably going to die.

As I am willing entering the rats fortress.

For the stupid exam.

Of course I prepared for it.

Insert AFO drinking tea and reading a book titled how to behave like a hero for 200 years old demon lord. Oh, how he loved this book that he randomly found in an ancient bazar.

And of course I tripped, and I couldn't stop my fall, as rat was probably watching for anything suspicious. Not that I could anyways.

Then something, or more properly someone stopped me midair. Anti-gravity quirk. Rare but non unseen.

Well, as I had to be cool, I did a flip, and the girl understood what she had to do and stopped my flight at just the right time.

Then I turned to her and… wait how was it ehh, oh that's it. “Thank you for your assistance my lady.” And I got on my knee and kissed her hand, exactly as my book told me.

My acting skills were perfect.

Uraraka

What the hell?

AForiya

For the theoretical exam, I rather simply cheated. What, do you think I remember calculus? And also I am evilTM. My genius mind and great eyesight did the job.

Nedzu:

Huh this student has every single answer wrong. And he also copied them from this student. Who had different test. And was half the room away.

And so laugh that caused mass destruction or at least couple of deaths sounded again.

AForiya

And then the practical part. I checked my book:
Extra deaths are bad, but you get points for style. For style refer to capitol heroic styles. Remember to behave like a gentleman. Don't hit women, it causes bad reputation. Don't kill your enemies unless no other options are available. Don't cause excess property damage unless you can pay for it. Most importantly, risk your life to save another. Always.

There was a lot more, but I am way to lazy.

After all I already have a way to get full points for style.

Not with this amazing samurai armour I got from Temu. Just 50 dollars, it was a steal.

And an actually good sword I got completely legally.

And with the mad training I had to go through, it was easy enough to move with it. I had no idea how to cut with sword, but that shouldn't be that hard right?

What am I even supposed to do again?

I started running cause everyone else did so. Apparently our objective was destroying robots. They were rather terrible at staying functional, judging by the fact that I could just cut them, or more properly bash them with the katana and after a bit they no longer moved.

All these children are pathetic really. No imagination. A caveman with stick is more creative than whole lot of them. Not that I am much better as I have no clue how to use one for all as I tuned out his monologue because of the HAIR.

Then I saw perfect opportunity to prove my heroism. As my book said, risking your life to save another is always great.

I saw that a girl was in danger from a giant robot. Now, time to seriously try that One for All stuff. Naturally, I jumped, with the One for All. Finally it chose to help. Naturally, my armour disappeared. Shitty Chinese manufacturers, I swear they got worse after quirks started being the new norm. While in the air, I pondered my choice for heroic scream (it's too very important to establish a brand, the book said). Finally I settled on copying one of my favourite fictional villains.

“Galaxy Impaaaaaact!!!!!!!”

One for All agreed with me, making a rather colourful visual effect while robot flew away. Then I found a slight problem. I was floating mid air with broken legs and arm. With my exquisite collection of quirks it would be no problem, but I only have access to OFA at the moment. What even happened with all those other quirks? Strange, I didn't even think about them until now.

Damn you Yoichi, trying to kill me even beyond grave. And with a quirk I gave you. Huh, why do I feel like saying not this time you stupid bastard.

Naturally, my perfect intellect already figured out a way to survive. If I could time my punch just right, I could survive. Sadly, I couldn't do more flexing as someone else saved me. Apparently, the girl read my book about heroism too, as she pushed through injury and needlessly saved me to get more points.

I floated down to ground, at last moment doing a victory pose with my single unbroken arm, until I landed on my face because my legs were broken.

Then nurse appeared. I was first scolded then healed from my horrific, very self inflicted wounds. Well, at least I surely got enough points for heroism.

Well, now it's time to go home.

Very cracky addition

Week later, with Nedzu

Mail:

I did some property damage, so I sent 400 thousand yen, so I hope this makes us equal.
Izuku Midoriya.

PS: I know about your abuse of cheap labour for your fake cities, you aren't getting another dime out of me.
PSS: I also know about the other ones.

Oh how special, Nedzu thought. Many knew about Cementos, but only couple knew about his Piper, Electrician and Furniture guy. He must have done truly an outstanding research.

AForiya: Vague threat of blackmail, that will get him. The rat will surely connect that to something.
