Inko midoriya sat in the sterile doctor's office, her son izuku was unusually still when sitting next to her, he was normally an active child, but he had become quiet and reclusive in the past few days, something which unnerved the green-haired mother. Apparently, there had been a row between her son and another boy at his preschool, a fight had broken out and there had been several people claiming that izuku had taken another boys quirk. This, in her mind, made no sense, Quirks were a genetic mutation, not something that could be given and taken. After the incident she would often find izuku in empty rooms in their small home, staring at his hands in silence, as if trying to spot something that was not there.

The middle-aged doctor opened the door and walked back into the office, he wore an expression of puzzlement, and he turned to the mother and enlightened him on the situation

"Mrs Midoriya, your son appears to be an anomaly, he has only one joint in his pinkie toe, as is displayed in all quirk users, and also has the 24th genome, the one that mutated upon the appearance of quirks, but he showed no signs of any abnormal powers in the testing, and upon genetic analysis, his quirk genome appears to be in flux, something that has never been displayed before. It has everyone who looks at the case truly stumped." Inko frowned at this,

"there was an incident at his preschool that occurred a few days prior, there were several people who claimed that izuku had stolen another boys quirk, but that was dismissed as childish imagination by the teachers, do you think there could be some merit to that theory?" the doctor's eyes widened at this and he turned to face the four-year-old child.

"my quirk allows me to stretch my limbs around two meters in any direction, I want you to focus on my quirk and place your hand on my arm, and think about taking it from me, and using it yourself. Can you do that for me Midoriya-Chan?"

The small; boy nodded and closed his eyes, before placing his hand on the older man's arm, a small flash of blue-white light came from Izuku's palm. Seeing this, the older man tried to extend his limbs to touch the wall on the other side of the room, a task that would ordinarily be no problem, but nothing happened. When the doctor gestured for izuku to do the same thing, he watched in astonishment as his arm extended and touched the wall, almost 2 meters away.

Izuku looked back at the doctor with something akin to regret in his eyes, he began to tear up and tried to apologise for taking the mans power, but to both mother and sons surprise, the man began to laugh.

"Incredible, I've never seen anything like it, Mrs Midoriya, your theory was correct" he turned to the now worried looking boy "Midoriya-Chan, I want you to do the same process as last time, but focus on giving me back my power." The young boy rushed to do as he was asked and when he placed his hand on the older man's arm again, a similar flash of light occurred and the doctor tried to stretch his arms again, and succeeded in the same wall touching motion the younger midoriya had demonstrated just minutes ago. The doctor wore a look of shock on his face and turned and grinned at the small green-haired child. He spoke into the now quiet room,

"Absolutely astounding, would you lend me a few moments," He walked out. Izuku began to panic, what if the doctor was going to call heroes to come and arrest him? After all, only villains steal, at least that was what Kachan said anyway. A few minutes later, he walked back in, holding a piece of paper with a printed coloured pyramid on it.

"This is a quirk rarity graph," he pointed at the bottom block "This is where your typical enhancement type quirks are, you know the type, super strength, super speed and similar."

he pointed at the second to-bottom block "This is your basic transformation and mutant type quirks, hardening and extra limbs and the like." He pointed to the middle block

"This is what we call the elemental block, most quirks in the block allow the user to control most natural elements and forces, such as fire, water, air and earth." he pointed at the second to top block

"This is your rare and combination type quirks; usually they are a meld of the two parental quirks, say for instance that a child had two parents with element quirks, in rare scenarios the two quirks might fuse and create a child who could use both." he pointed at the top block

"These are your reality-bending types such as the ability to slow time, teleport and rewinding, only a few people have ever been recorded with these quirks, I would say as few as five." He then drew another triangle above the top triangle block

"This is where your son's quirk falls, this is the first quirk of its type ever to be officially recorded, I would like to say that I am glad I saw, and experienced, it in person. This will be formally noted, and your son's quirk registered; thank you for bringing your concerns to our attention, and we thank you for your help in discovering this newfound ability." With a bow to both Midoriya's he walked them both out of the office and into the car park, where mother and son got into the car and drove away, the doctor turned back into the office and shut the door behind him, he had several phone calls to make.

A few days later

Inko midoriya was preparing Katsudon for her son in their small kitchen, when she heard a knock at the door, turning the water down to a simmer so she didn't overdo the rice, she navigated her way through the minefield of toys izuku had created in their living room, where the boy himself was immersed in an all might TV show, when she got to the front door, she undid the lock and peered through a crack, and saw a tall, plain-looking man in a trench coat, she opened the door fully and turned to face the man, he took the first step and greeted her,

"Hello ma'am my name is Naomasa Tsukauchi, I'm a detective with the police force, we have received an anonymous tip from an undercover hero that your son has a very powerful quirk, one that could help contain potentially volatile captured villains." the man said showing her his badge. He chuckled slightly and looked at her,

"I know this seems sudden, but this was a one in a million find, and if you and your son are willing to work with us, there could be astronomical progress on the protection of innocents from repeat villain attacks. With you permission I would like to speak with your son on the matter" Nodding her head to show she was in agreement she let the man in and sat him down with izuku and left the two alone at the detective's request. The detective adopted a warm tone and

"Hello Midoriya-Chan, I was sent by the police force to talk to you today about your newfound power to give and take quirks, we would like to work with you, and use this power to help stop villains from hurting innocents after they have been captured, would you be willing to aid us with this?" the man stared into the eyes of the child sitting Infront of him, they were gleaming with intelligence and experience beyond his years. After a few moments debate, the green-haired child looked at the man Infront of him and nodded

"I want to use my power for good, to prove that although my quirk sounds evil, it will be used with only the best intentions."

"Very good, I'm glad I'm going to get to work with you Mr midoriya, now, down to business," he pulled a small folder from inside his coat and placed it Infront of the younger boy. Picking it up and glancing over the crucial information, it was information about a recently captured villain call Zephyr, his quirk was called storm and allowed its user to create copious amounts of wind and lightning from their body, he had already made three attempts to escape custody and had killed five guards, a truly horrible person.

"This is the man we want you to take the quirk of. As you can see, he is not happy with being locked up, and we want your help to keep him contained permanently, would you be willing to do this for us?" The small boy just looked up to the older man and nodded, he soon asked a question that had been burning in his mind,

"I'm willing to help you keep this guy locked up, and to take his quirk if that is truly what is required," he shuddered at the thought of taking another's quirk, which confused Tsukauchi but the boy pressed on "What do you want me to do with the guys quirk if I have to take it from him?"

"After you have taken it, it's yours to keep.," said the detective said with a nod, "But we need you to promise that you will only do good with these quirks we give you, always remember what a hero would do." Izuku finally smiled for the first time during their encounter as he recited the phrase that his idol all might so often said during interviews

"A hero would only ever use their quirk to help others and save people, and that's what I plan to do!" Izuku grinning at the older man.

A week later

After the meeting izuku had be wracked with anticipation and nerves, he was about to be taken to Tartarus, the most secure prison in the entirety of Japan, to take the superpower of a deadly villain, it all sounded so surreal. When Tsukauchi appeared outside their door the following week, it all came into contrast, this was his life now. The detective beckoned to izuku to get into his car after he said goodbye to his mother and the duo set of to the most secure place in japan.

When he finally caught sight of the building he was amazed by its sheer size, the place was a fortress of black iron and stone, izuku then made a mental note to never abuse the power he was given, he did not want to end up in a place like this.

After being taken through what felt like a hundred different doors and checks, they finally arrived at zephyr's cell. Another man was standing at the door; he had shoulder-length black hair and what seemed to be a scarf wrapped around his neck, He looked like he needed sleep and a shower, but reluctantly dragged himself to the meeting point outside the villain's cell.

"Ah Aizawa, good to see your here already." the man called Aizawa turned to them and his eyes caught sight of izuku for the first time, to say shock showed in the older man's eyes would be an understatement.

"This is the kid Tsukauchi? I know he said he was ready, but he's barely out of pre-school, bah well I guess he'll do the job just the same," he looked down at the young boy and offered his hand for the boy to shake "My names Eraserhead and I will be helping you take this villains quirk today. It's a simple process, and I erase his quirk while you go and take it from him."

"I'm ready," said Izuku "I know how your power works, so as long as you keep him from being unable to use his lightning, I should be able to take it from him," izuku said with a determined face.

"let's do this," said Tsukauchi unlocking the door and sending izuku in with Eraserhead close behind him. The villain was strapped to a chair with his hands in insulated gloves. He had shoulder-length hair and dark skin with visible veins running up his face and arms, the only bare skin visible.

"come to have a laugh at me, have you? It's not nice to make fun of the helpless kid", said zephyr with a cruel laugh. He saw the man's hair stand on end and but suddenly drop again as Aizawa glared at him and he looked up in surprise. He suddenly looked to the other man in the cell, his eyes were glowing an unnatural red and he felt helpless as the younger boy walked towards him. He called out to the older man in surprise, "What did you do to my quirk! I can't use it!

"Now Midoriya! I can only hold this for so long!" Aizawa called to the slowly progressing child. Izuku walked forward and placed his hands on Zephyr's forehead. He spoke to the squirming man Infront of him

"This is for hurting people with your Quirk. If you are as powerful as you have demonstrated to be you should have used your power for good, not evil." And as he spoke this a blue-white flash came out of his hands and the villain went limp. Midoriya suddenly felt a course of energy sweeping through his body and was tempted to let it loose, but he remembered what Tsukauchi had said, heroes only ever used their power to help and protect people, And the wave stopped as soon as it had started. a tinny voice came out of the speakers in the room.

"prisoner 2974: zephyr, neutralised."

-well, here's my first foray into , I have no clue whether or not this was any good, so if you could please review and tell me your thought that would be amazing!

Thanks!
