A New Quirk

Yeah, I'm working on this story and giving it a few adjustments and more specifics because it does sound like a little bit like another story. But I'm about to prove that it's not the other one, because the other 'story' doesn't have a way to erase AQs which mine does and my Izuku is an absolute madman who is driven by revenge and will be driven into a deep state of madness. Let's get rolling.

A mist man said, "You must be Doctor Insanity."

The teen next to him asked, "Who is this Kurogiri?"

Izuku said, "That is correct, I'm here for a All for One."

The TV with the words 'Audio Only' revealed a voice, "I've been expecting you Doctor Insanity."

Kurogiri opened a portal for Izuku to walk in which Izuku looked in the room to find AFO (All for One) on his chair with breathing equipment on him. Izuku sat in front of him to say, "You don't look so good, but I still want this partnership though."

AFO chuckled, "Why not join?"

Izuku said, "I need resources for my quirk erasing drugs which only Overhaul can provide, and you are the only one to provide for my artificial quirks which is why a partnership is better."

Then Izuku touched AFO to repair him entirely which Izuku said, "This is artificial quirk number 49 'Overhaul', I can make an artificial quirk of your quirk but only if you want to."

AFO laughed, "I will agree on the partnership but I want the artificial quirk of my quirk so I can give to Tomura. Can you do that?"

Izuku chuckled, "Over course I can but I need your blood for it to happen."

AFO agreed to give Izuku the blood which Izuku got enough blood for Tomura, Shinso, himself, and a little bit extra. Izuku then warped himself back to his lab which he got to work on the artificial quirk All for One. When Shinso came back in his vigilante outfit Izuku said, "Brainwash, I got All for One and you will the first person to receive it."

Shinso asked, "So with this quirk I can steal quirks and give quirks?"

Izuku with a sinister smile, "I modified it to take artificial quirks as well, but I also got something else as well."

Shinso took the pill to give him this new quirk which Izuku pulled out a few syringes and said, "I reverse engineered my quirk erasing drug and found away to make us unable to lose our many quirks to our own quirk erasing drugs."

Shinso asked, "Like a vaccine?"

Izuku snapped his fingers, "Bingo, but for now each syringe only last about a week so this will be a weekly thing until I find a permanent solution."

Shinso was now interested in everything Izuku was doing while he was gone, but one question came to mind, "Izuku."

Izuku turned around, "Yes Shinso."

Shinso asked, "Why don't you become a vigilante or something heroic like that?"

Izuku looked down, "Because he told me I couldn't."

Shinso asked, "Who?"

Izuku said, "All Might"

Shinso was in shock which Izuku told him his full story of his quirkless life to his discovery of the stuff they have today. Shinso said, "I do share a similar pain but no like you."

Izuku listened to his story which Izuku said, "People are stupid it's not the quirk that makes the person, it the person that makes the quirk."

Shinso said, "It isn't power that makes a hero, it's the person that makes the hero."

The two chuckled which Izuku said, "Too late for me to be a hero, I have accidently killed people to make the power we have today which speaking of which…"

Izuku took his AQ of AFO and made the other to give to Tomura then continued, "I know have enough for one more person, so I was thinking…"

Shinso looked at him, "What are you thinking?"

Izuku chuckled, "I'm going to modify it a little bit differently make it into a new quirk entirely."

Shinso asked, "Don't you have to modify the person to modify the quirk?"

Izuku said, "That's the fast way. I can do it with just the blood, but it takes weeks. Anyways I thought about how much of our own supply of quirk erasing drugs we are using so I will make a quirk to erase quirks permanently."

Shinso asked, "What do you mean?"

Izuku said, "All Might's quirk is 'One for All' as in one quirk for everyone. 'All for One' is all quirks for one person. I will make this new quirk 'None for All' as in no quirks for everyone."

Izuku laughed in madness which Shinso put his hand on his shoulder, "Okay, calm down. I like the idea though, you should start working on it."

Izuku said, "Because science, of course. Imagine the world would think that a quirk where one touch and quirks disappear like not even stolen but just to disappear because their quirk is just that useless to me."

Shinso said, "The world would fall to their knees, I going to head out to do vigilante work."

Izuku said, "The list with names and locations are on your desk."

The warehouse was really big for Izuku and Shinso for them to put lab equipment, a gym, offices, and other stuff; which Shinso went to his office to pick up his list and headed out for his work. No one knows that Brainwash works for Doctor Insanity but if they knew he would be labeled from vigilante to head hunter, but Shinso felt that he was doing the greater good. He was cleaning the streets of crime because his multiple quirks can defeat anyone who crossed him, which now he was heading to Hosu.

Hosu

Shinso was swinging around Hosu catching villains left and right until he was on the roof top crossing names off. He said with his mask muffing his voice, "Well that makes 160 for tonight."

Then a voice said, "So if it isn't Brainwash."

Shinso turned around to find Eraserhead, which Shinso asked, "Can I help you?"

Eraserhead said, "I want to meet you and ask you a few things."

Shinso thought about it then nodded, Eraserhead wrapped his scarf around Shinso which Shinso use his electric quirk to electrify the scarf forcing Eraserhead to let go of his scarf. Shinso used his scarf to tie up Eraserhead then Shinso chuckled, "You said you are here for questions, so I will listen and answer your questions."

Eraserhead asked, "What is your quirk first of all?"

Shinso said, "I actually have about 51 quirks, my original and artificial."

Eraserhead in shock, "How did you get the quirks?"

Shinso said, "From the person who created them."

Eraserhead asked, "Who do you work for?"

Shinso said, "I work alone to clean the streets of this city because no one else can."

Eraserhead raised an eyebrow, "What makes you think no one else can?"

Shinso chuckled, "I've seen heroes overpowered by the artificial quirks and you can't erase them because they are not like normal because they act different. But they can still be erased…"

Shinso pulled out a normal QED and an artificial quirk erasing drug (AQED), "What is the difference between these two here besides color?"

Eraserhead looked at him in confusion which Shinso chuckled, "The white one erases normal quirks and the red one erases the artificial, that is the difference between two. I know a guy who has access to this stuff, and I use these to clean house."

Eraserhead looked at him, "Well, what are you going to do?"

Shinso put the two drugs next to Eraserhead, "I'm a fan of yours for a long time so I'm going to leave you to untie yourself and you can have those drugs for you to look at."

Shinso flew off leaving Eraserhead who broke out and took the drugs to have them examined. Eraserhead continued his partol until he came across Endeavor which he was being an asshole until they heard laughter. They turned to see Doctor Insanity (Izuku) which he said, "Well if it isn't Captain Flame Beard and The Night Shift Hobo, I haven't seen you two in a while."

Eraserhead has been trying to find him for a while because he was the creator of AQs and caused this chaos. Eraserhead was thinking that he should've wished Brainwash to help them with this one, Endeavor shot the biggest fireball at Doctor Insanity which Eraserhead said, "What the hell is wrong with you?"

Doctor Insanity laughed as the ball of flames did nothing but get absorbed which he said, "Arificial quirk number 37: Absorb and Release; what an interesting quirk."

Eraserhead tried to erase his quirk but he laughed, "Eraserhead didn't you learn last time that you quirk can't effect my quirks. Well I guess I have to reteach you."

Eraserhead got punched in the face and sent flying into a wall, which Doctor Insanity grabbed Endeavor's face and Endeavor screamed in pain until he passed out. The doctor started creating flames with his new quirk and laughed, Eraserhead looked up to asked, "What did you do?"

The madman said, "My new artificial quirk, number 50: All for One, took his quirk and left him quirkless. His quirk is now mine."

Eraserhead looked at him in shock which then the madman knocked out Eraserhead and carried him back to the lab.

The Lab

Izuku was having a good day he got the call that he can take Eri with him, he made All for One, and now he was going to make a modified version of Eraserhead's original quirk. Izuku was asked by Shinso to not kill him which Izuku agreed with Shinso and settle with modify and release plan. Izuku got Eraserhead's medical file from bribing a few people and saw many problems with him and had no problem showing Shinso the medical records. Izuku was going to be a doctor to fix those problem even if it was illegal, which Izuku was sitting on his chair next to Aizawa checking the records one last time and checking to see if he got everything.

Aizawa woke up and Izuku said, "Ah Shota Aizawa, can I call you Shota or Aizawa? Well I guess it doesn't matter I got to modify and copy your quirk."

Aizawa asked, "Why not take it like Endeavor?"

Izuku laughed, "Your quirk doesn't erase my artificial quirks which is why I going to modify it."

Aizawa asked, "How are you going to modify it?"

Izuku looked at him, "I got to modify you to modify your quirk."

Izuku pulled out his equipment, drugs, and parts to replace some of his organs, which he said, "I will let you know in advance, I would be lying if I told you it wouldn't hurt."

Izuku injected Aizawa with painkillers and gave him a leather belt to bite down on then said, "Even with painkillers."

Izuku started injecting the syringes in his veins, then cut him open to inject steroids directly in his heart and replace a few organs with the parts. Izuku then went for Aizawa's eyes to fix them to where he would never need eye drops again, then after a few injections in the eyes and brain Izuku went to his chair and said, "Good night Aizawa, in 5 hours you will have a new and improved body and quirk."

Aizawa passed out from the pain and Izuku set the timer to then sleep. After the five hours were up, Izuku got up to check Aizawa's health which to say, "Everything is better than expected, you really do pull through Aizawa."

Izuku checking his condition fully, he went to the TV to relax a little bit. The news was talking about Endeavor being found in a coma and Brainwash's arrest count of last night which he said, "You keep this up I think you might have fan selling merchandise of you."

Shinso sat next to him to say, "Just doing my job, I like this new All for One quirk."

Izuku chuckled, "So do I."

Shinso asked, "After this whole revenge and killing All Might and Bakugo, what are you going to do after that?"

Izuku smiled, "If I haven't fallen into deep madness… I guess leave the country and go to a tropical island…"

Shinso was nodding to the idea so far and Izuku said, "I will live on that island for the rest of my life with pretty girls around me and beautiful sunsets. Maybe I will make my own tropical island and invite some beautiful models to live with me."

Shinso was laughing his ass off, "Is that is your plan? I would love to go see and live like that."

Izuku laughing with him, "No, I'm serious. Imagine us living on an island that was just created and not on the map, I shot up our own satellite to have our own internet, and with our warping quirks we can bring anyone we want."

Shinso smiled, "That sounds like a nice idea and probably your sanest ideas I have ever heard from you."

Izuku said, "Okay, you should leave before he wakes up and don't you forget your 'Wake Me Up' coffee."

Shinso in sarcasm, "Okay"

Shinso left for class and after a few minutes Aizawa woke up which Izuku said, "Well I'm going to give All for One the other copy of his quirk and give Overhaul my new quirk erasing drugs to begin gaining their protection as well. You should continue to get some rest."

Izuku went off to do his deliveries to get what he wanted, he went to AFO to give Tomura the quirk with AFO started to train Tomura on it. Izuku got protection and resources for more AQs then Izuku went to Overhaul to pickup Eri and Overhaul sent Izuku his resources. Izuku warped his way to lab with Eri on his shoulders with a smile on her face. Izuku put her downto say, "I told you I will get you out of that monster's place. Now the only rules here are don't touch the chemicals and don't free anyone on the tables like Aizawa here."

Eri pouted, "What did you do to him?"

Izuku chuckled, "I kidnapped him, enhanced his quirk, made a copy of his enhanced quirk, and enhanced his body."

Eri punched him in the leg, "You can't go kidnap people that is wrong."

Izuku chuckled, "Well I can't just throw him out, he still has to recover from the blood loss and adapt to the changes I made to him."

Izuku took her to her new room and tucked her to bed which when he came back, Aizawa glared at him, "Why do you need the girl?"

Izuku glared back, "They used her to make quirk erasing drugs, they took her blood and pieces of flesh off her to make it. But I came in to stop her suffering, I show them that the quirk erasing drug I make without a single piece of her. I made a trade to give them my services in exchange for her, I don't like seeing children suffering for science."

Aizawa raised an eyebrow, "But you have no problem with adults."

Izuku laughed, "That is correct, Aizawa! Because science, of course! Besides who is teaching your class, if you are here with me?"

Aizawa didn't say a word which Izuku said, "Now for the medical report, well good news is that you are in great health but you're going to be here for about two days to recover. You lost a lot of blood and you have to start getting use to the upgrades."

Aizawa in confusion, "What upgrades?"

Izuku said, "Well the ability to erase my artificial quirks, getting rid of your dry eye for good, a few organs replace to work with your coffee based diet, enhancing a certain part of your brain to allow you to give you energy despite your lack of sleep and lastly the ability to where after three hours of sleep give you energy for the rest of the day."

Izuku then took some blood from him to make two copies and a little extra of his quirk then put it through his machine to create it in seconds. Izuku said, "Well you are still in pain so I going to put you on pain killers while you are here."

Izuku hooked Aizawa on pain killers to lessen the pain which Aizawa fell asleep as Izuku laughed. Izuku went to work on his side show 'None for All' which he began muttering, "I need the quirk to where one touch can not only erase the quirk but prevent All for One from giving quirks or if they take AQs to actually give said person a quirk and that any offspring of their will be quirkless as well…"

Izuku knew that combining All for One and Erasure were part of the answer, but he needed a one more quirk to solve the equation. He was losing his mind again until he knocked over his stack of papers, he picked them back up and looked the words All for One backwards. He remembered his conversion with All for One who revealed All Might's quirk and Izuku thought to himself, 'That's it, One for All is two quirks in one; one is the stockpiling quirk and the other passes quirks. If I can get the passing part, then I can fully create None for All."

Izuku started laughing in madness until he asked himself, "Now how will I capture All Might?"

But then he realized All Might needs a successor and he most likely found one, which he said, "That's it I don't need that muscle idiot, I just need his successor."
