I don't own Marvel or BNHA

Izuku woke up slowly. His eyes felt heavy, and all of his tiny undeveloped muscles ached. It wasn't until he reached up to straighten his hair that he realized one important detail.

He was in handcuffs.

Once he came to that realization, he quickly came to several more. He wasn't in his bed, but on a dingy cot with a semi clean woolen blanket. There was an exposed toilet and sink in the corner of the room, but no mirror over it. He wasn't in his room, he was in a jail cell.

Izuku felt his heart rate spike as panic began to spread into his bones. He felt a warmth spreading through his chest and begin flowing through his body.

Then that feeling was cut off and Izuku almost collapsed on the floor, barely managing to catch himself on the edge of the bed as he made to stand.

"He was right after all, my quirk only works if you are in the process of transforming." A dry tired voice spoke from the other side of the bars. Izuku turned his attention to the figure on the other side, who was leaning against the far wall, his goggle covered eyes facing Izuku in an intense stare.

He was dressed in all black and had long black hair that looked like it was constantly ruffled. Around the man's neck was what looked like a long white bandage. If Izuku had to guess, he was still in his early 20s, but the lines on his face made him seem older.

"What…" Izuku tried to ask, his voice stumbling as he took in man that looked to be a hero.

"Your quirk activated for the first time, sent you on a rampage, you injured several pros and bystanders before you were brought under control. So now you're here until the higher ups can decide what to do with you." The man said, his voice never wavering from its deadpan.

"But, the doctor said I didn't have a quirk, that I was quirkless…" Izuku said in a small voice, curling into himself as he sat on the old bed.

"Well they were wrong, and there's a hospital ward full to prove it." He replied before falling silent, his gaze still set on Izuku.

Izuku could feel his heart racing again, once again in fear, but for a different reason. He had hurt innocent people, he had hurt HEROES. How monstrous was his quirk that he would do something so against everything he stood for.

He felt his heart start to race again, the warmth spreading through his chest, until once again it was cut off and Izuku almost fell over again.

"Stop doing that kid, you're giving me dry eye over here." The man complained, rubbing his brow over his goggles.

Izuku paused his thoughts and took in what the man had said.

"You mean that warm feeling in my chest, that's my quirk activating, and you're stopping it?" He was watching the man closely, he was pretty sure he knew who this was, but it didn't hurt to be certain.

"Yeah, I'm erasing your quirk, that's why I'm here."

"You're Eraserhead, the new underground hero who specializes in ambush tactics and busting crime rings." Izuku felt his heart rate spike in excitement as he gushed about the hero in front of him, the warm feeling once again spreading before it was stripped from him for a third time in as many minutes.

"Geez kid, are you doing that on purpose or is your quirk just going off on its own?"

That cut Izuku off of his rant more than the cold feeling in his chest.

"Its my quirk I guess, I'm not trying to use it." He mumbled out as Eraserhead gave a sigh of resignation.

"I thought so, but you'll have to get a handle on that if you ever want to get out of here, because I can't follow you around everywhere keeping your quirk in check.

"Eraserhead, is he awake." A voice asked from down the hall, drawing the attention of both the child and the hero in the jail.

"Yeah, are they ready for him Naomasa?"

"We are, you have been requested to stay with us just in case though." The voice, apparently belonging to a man named Naomasa, replied and Eraserhead made his way to the door of the cell and opened it, beckoning for Izuku to follow him out.

Of course, Izuku's heart rate spiked and Eraserhead was once again forced to erase his quirk before whatever it was could take hold.

Izuku made his way from the cell, down a series of hallways, and into a small room, where three men were waiting for him, with Eraserhead bringing up the rear.

The man in the middle and sitting opposite from the table was an average looking man, dressing in a detective's uniform, the coat hanging over the back of his chair.

The second was a tall lanky man with sagging blonde hair. His blue eyes seemed to go right through Izuku, unnerving him. At first Izuku thought he was almost skeletal, but under the man's oversized white shirt, he could see a foundation of muscles that rivaled a professional bodybuilder.

The last man was older. He had a large white mustache and his white hair was slicked back. He wasn't of Japanese descent, but the American military uniform pointed to his origins.

"Welcome Izuku," the detective in the middle spoke in a calming voice, "I am detective Tsukauchi Naomasa, and while I would like nothing more than to let you go, there are a few things that need to be addressed first." he explained, his voice soothing Izuku and keeping him calmer than he would have been.

Izuku gave a shaky nod, the handcuffs around his wrists making a light clanging sound against the table as he did so.

"Is it really necessary to have him in handcuffs." The blonde inquired, glaring at the offending pieces of metal around Izuku's wrists.

"Unfortunately yes, until this meeting is over, I am required by law to leave them on." Naomasa replied with a sigh, giving a small glare at the American, who only nodded stiffly.

"Alright, let's begin then." The blonde said, focusing his attention on Izuku.

"Name, Midoriya Izuku. Age 4. Two months ago you were diagnosed quirkless by Dr. Daruma Ujiko. Our own tests have pulled the same conclusion. There is an explanation for this however, Yagi if you would." Naomasa said, gesturing to the blonde.

"Of course detective. Young Midoriya, I have worked with your father, one Dr. Bruce Banner in America before. He possesses the same quirk you do. In America, he is kept in a government laboratory and under watch at all times in case his quirk activates. He is only allowed to use his quirk when the government deems it appropriate and they deploy him only in worst case scenarios." As Mr. Yagi spoke, Izuku felt his head spinning as he took in information he had never known about his father.

"Dr. Banner is a friend of mine, and I believe the reason you appear to be quirkless to our tests, is his doing." Mr. Yagi continued, his face aging before Izuku's eyes. "Your father hates his quirk, and has been experimenting on himself in an attempt to get rid of it. About six years ago, he believed he was successful, and he passed the tests put forth by the American government and was released from the labs he was being held in. I was the one who brought him to Japan to celebrate his new found freedom, and that was when he met your mother, Midoriya Inko." The more he spoke, the more Izuku couldn't believe what he was hearing. It was almost surreal to him.

"They were quickly married, but several months after you were born, the American government decided that it was too dangerous to have him out of the country, and he was deported back to America and sent back to the labs, as a full time researcher this time instead of only part time. He believes his quirk to be permanently gone, but either he wasn't as through as he thought, or he only got rid of it in himself, but not his ability to pass the quirk down. My belief is that he destabilized his own quirk factor, which made it so while his quirk is still present within him, he has locked it away. When you were born, you inherited his quirk, but it changed as it became your own quirk. Your own quirk factor is unstable like your father's, but instead of preventing your quirk from activating, it instead makes you seem quirkless to the normal tests, when the truth is you are anything but." Mr. Yagi concluded, his sharp blue eyes watching Izuku carefully.

"Which is exactly why he should be taken to America and undergo the same procedure as his Father, to lock away his quirk. The world doesn't need any raging berserkers running around." The American barked, his eyes boring into Izuku, who needed another erasure form Eraserhead to keep his quirk from activating from his fear of the American.

"May I remind you General Ross, that you are only a visitor here on Japanese soil, and that Izuku is a Japanese citizen. While we appreciate the offer, that is not how we operate here." Naomasa harshly rebuked the man, his kind eyes darkening at the general.

"Before we reach any conclusions, would you mind telling us what you remember from the park young Midoriya?" Mr. Yagi asked, the tone of his voice softer.

And so Izuku told them. He told them about the bullying trio, although he refused to name them, he told them about the injured boy who had joined them, and he told them about the anger he had felt before the warm feeling overtook him and he blacked out.

"I see, very well then. In accordance with the First Awakening Act, you will not be penalized for any actions that occurred during the first time you used your quirk. That being said, you will be held responsible in the future." Naomasa said, finally taking the handcuffs off of Izuku, who could only feel relief.

"That being said, you need to learn to control your quirk, not let it control you. My recommendation is to have your mother enter you into a quirk rehabilitation center, where you will get experience in how to control your quirk in an environment where you can be controlled if you do lose control." Mr. Yagi continued, drawing a snort from Ross.

"Good luck controlling that monster. It would take someone as strong as All Might to keep him down." Ross said, disdain staining his voice.

"Seeing as I work in his main office and know All Might is on good terms with Dr. Banner, I'm sure he would be willing to work with Young Midoriya when I inform him of the situation." Mr. Yagi shot back.

Izuku needed another erasure as his heart spiked from excitement. All Might, willing to help him. He had so many questions he wanted to ask the number one hero. Eraserhead and Naomasa both gave small snorts at his obvious fanboy tendencies. Mr. Yagi only looked amused.

"And asie from All Might, I can keep him from transforming and my colleague Midnight was the one who knocked him out this time, and both of us would be willing to help from time to time." Eraserhead added on the Mr. Yagi's point, drawing a warm smile from the blonde man.

Ross gave one final grunt of disagreement before turning sharply and leaving the room. Izuku was glad to see the American leave. He finally had a quirk, and even if he couldn't control it right now, he had one. And that meant he could be a hero.

"Uh, before I leave," Izuku started, surprising Naomasa, who had been going over some paperwork, "But, what exactly is my quirk?" Izuku asked, drawing a nervous look from all three men in the room.

"We can play the news report for you, but they aren't very nice in it." Naomasa warned and led Izuku to another room, Izuku assumed it was his office, and he pulled up a video on his laptop before turning the machine so Izuku could watch the video.

Izuku watched in muted awe and fear as the news reporter commentated the fight between a small grey-green skinned berserker with two tone hair and Death Arms. He watched as almost a dozen sidekicks were tossed aside with barely a second thought. He watched Eraserhead get casually tossed aside. Death Arms and Ingenium both getting injured terribly until Ryukyuu and Midnight finally took the berserker...him...Skaar...down.

Even after the video ended, Izuku stared at the black screen, still absorbing what he had seen. He could see why General Ross thought he needed to be controlled now. That much raw power and fighting ability, and it was only the first time his quirk had been active. The amount of power his quirk would obtain naturally without him pushing it become a hero was monstrous. With proper training, Izuku had no clue how strong he could get.

Even as all these thoughts came and went, one thought stuck in his mind. He had seen that kind of fight before. From the only person to ever out power All Might in a fight.

"My dad's the Hulk." Izuku breathed out, his heart beginning to race. For what felt like the hundredth time that day, Eraserhead was forced to shut down his quirk from emerging, keep...Skaar...from emerging.

"Yes, he is. His identity is a guarded secret by the American government, but as his son, you have the right to know." Mr. Yagi responded, his eyes belaying some emotions Izuku couldn't decipher.

"Come on Izuku, your mother is here to pick you up." Naomasa said, gently leading the still shocked Izuku from his computer.

After a tearful reunion with his mother, one that required Eraserhead to erase his quirk again, Naomasa gave Inko his recommendation.

"Take him right from here to the Mustafu quirk rehab center. They're one of the best, and Eraserhead can stay with you for the trip there to ensure nothing goes wrong. He may not have been punished for his first offense, but he will be for future ones." Naomasa warned, Eraserhead silently agreeing behind him.

"I-i…" Inko trailed off, still holding Izuku in her arms. "Ok, we'll do it your way, but everyone there better treat my baby boy right." Inko insisted, pulling Izuku closer to herself.

"It'll be fine, I'll drive you myself while Naomasa finishes the paperwork here." Mr. Yagi offered, giving Inko a reassuring toothy smile.

"Thank you Mr. Yagi." Inko said as they left the precinct, Eraserhead following the mother son duo silently.

The drive was filled with Inko voicing her worries about the facility while Mr. Yagi reassured her. Izuku just took it all in, still processing the truth of his quirk.

Skaar was unlike anything he had ever seen. He was untamed wild fury given form. Somehow contained within his scrawny frame lay a sleeping giant.

The whole ride over, Eraserhead didn't say a word. But his gaze never wavered from Izuku's own silent form. As they arrived at the large building that reminded Izuku of a fortress, he turned to Izuku and gave him a smirk.

"You got potential kid, now it's up to you to live up to it." And with that, he slipped out of the car and leapt up to the rooftop, where he could keep watch over the building.

Izuku held his mother's hand tightly as Mr. Yagi led them inside. There they were greeted by a receptionist, and after almost an hour of paperwork, a nurse came to show Izuku around the facility.

"My name is Nurse Anzu, if you would follow me Izuku, we can get you settled in. Your mother will be back tomorrow with your belongings." The nurse greeted cheerfully, easing some of Izuku's fear.

"Izuku." Inko called to her son as Nurse Anzu took his hand and began to lead him into the facility. "You can become a hero, a great hero." She told him a wide smile on her face, contrasting the waterfall of tears pouring from her eyes.

Izuku's whole world brightened as his mother finally said the words he had been dying to hear. The fatigue he had been feeling since he woke up in the jail cell finally fading completely as a new hope took its place. Tears of joy fell down Izuku's face even as Nurse Anzu led him through the facility.

"Since you're new here, it's our policy to assign an 'older sibling' if you would." She explained as the walked through the hallway. "One of the patients who has been with us for a time will show you how things work, and if you are here for long enough, you might be asked to do the same." Izuku just nodded as he took in the hallways they were walking through. The rehab center was built like a hospital, but with small comfortable apartment like spaces instead of the usual sterile rooms.

"We usually only have somewhere around 50 patients at a time here, some have to stay for years while other have a relatively fast turnaround time. Our most notable patient is the Rescue Hero 13. They were here for almost two years before being accepted into UA to fully master their quirk, blackhole." Nurse Anzu explained to Izuku, who was wishing he had a notebook to write in.

"And here we are." Nurse Anzu stopped at a pair of doors, one labeled and the other not. "You'll stay here, while your 'big brother' will be right next to you. If you need anything and don't feel comfortable going to a nurse, you can go to him." Nurse Anzu explained, knocking on the door.

When it opened, Izuku was brought face to face with a red haired teen, maybe 13 and 14 years old. He had wild spiky hair that stuck out in all directions. His face was gaunt and his frame was skinny. He seemed even more fragile than Mr. Yagi did at first glance.

"Izuku, this will be your 'big brother' while you stay here, say hi, why don't you." Nurse Anzu said, drawing a light chuckle from the teen.

"H-hi." Izuku said in a small voice, slightly intimidated by the older boy. His natural nervousness shining through as he worked to keep himself calm, to keep Skaar down.

"Nice to meet you too buddy." The teen said, reaching out and ruffling Izuku's own wild mop of hair. "My name's Toya Todoroki."

Somewhere else, Hidden Laboratory

All for One was a patient man. It was his defining trait. He could wait generations for his plans to come to fruition. But if there was one thing that set him off like nothing else, it was a wasted opportunity.

"You mean to tell me," He began, rage dripping in his voice as he stared down his top doctor and researcher. "That you had the son of the Hulk in your hands, but you didn't realize who he was until the heroes got their hands on him." All for One was almost spitting mad at this point.

Too many of his plans had been ruined by the great bluster that was All Might. The only time he had ever seen the man losing was against the Hulk, and he was locked away in America, far from his grasp. To hear that he could have stolen his son's quirk, but had missed the chance…

"The only reason I know is because they had to use my office's records to confirm it was him. They are keeping his identity extremely confidential." Dr. Ujiko protested, his knees shaking slightly from the presence All for One was exuding.

"Of course they are, and it would take an all out assault to get to the boy now." All for One said, plans and ideas spawning and being discarded rapidly from his mind. "We'll just make a note of him for now, and if they leave him vulnerable, we can exploit it. What did you say the boy's name was again?"

"Izuku Midoriya, but his alter ego identified as Skaar."

"Skaar." All for One said the name slowly, taking in everything he could from it. "I wonder what kind of piece you will end up being."

Dr. Ujiko could only give a sigh of relief when his boss burst into mad laughter. He was off the hook, for now at least. That meant he could get back to his research into artificial creatures. And the vial he had of Midoriya's blood might just give him the tools he needed to finally be successful.

Tada, chapter two, which is pretty much an info dump.

But info is important, so it has to happen from time to time. Next couple chapters will be in the rehab center, which will have a few characters there to befriend Izuku while he tries to control Skaar. These chapters will be important for future building, pretty sure its obvious who will be there.

General Ross completely wrote himself into this chapter, but it gives me options for the future so I'll take it. He's kind of a dick. And yes, All Might is involved with the Hulk, and even before his injury, he can be in muscled down form to be discreet. I honestly think his form change is his own quirk somehow activated by One for All, which starts a whole other debate for another time.

Thank you everyone who favorited and followed, it means a lot. Next story I plan on updating is Trickster, I've already got half of the next chapter written, I just need to finish it, then clean up a few points I'm not sure I want. Trickster is a delicate balancing act that requires multiple edits to keep from going into any extremes more than I want to.

Happy Reading -Centurion Africanus
