Forcibly His Successor

Chapter Text

At nine years old, there were two things Izuku knew: one, All-Might was the greatest hero ever and two, quirkless people were believed to be useless, no matter what they managed to achieve. So when Izuku met his hero on his way home one day, he automatically decides to mark the day as the greatest day of his life, ignoring that he had to be saved by said hero when the villain reached out to grab him. He didn’t think about the villain groaning on the ground, or the bullies that were chasing him, or even about the fact that everyone considered the quirkless as less useful than dirt. All that ran through the child’s mind was, “Can I be a hero without a quirk?” 


He felt his heart shatter when his hero looked at him with an unforgiving gaze. “Be realistic and have obtainable goals,” he said before grabbing the villain and leaping away. Izuku could hear the people behind him shuffle their feet awkwardly, before they started to move forward. Izuku barely reacted, doing nothing more than half-turning his head to the side to see how much he’d need to brace himself. He idly noted that Kacchan was walking the other direction, while the others came forward. Wind quirk, wings, elongated fingers, and then he stopped trying to figure out their quirks and simply stayed on the ground. Nothing mattered anymore. It was the worst beating he’d ever gone through. 




Rather than going home to a mother that would stare with a pitying gaze, Izuku headed to a beach not too far from his home, hiding in the trash to bandage his wounds. He eventually stumbled home, bandages covering cuts and bruises, his ribs wrapped with bandages, and an ace bandage on his wrist, to find a burned out husk of a home. His suitcase fell to the ground. He’d thought to come home from the week-long trip to Tokyo to find his mother waiting for him, but instead he only found a home that had burned down long enough ago that the heat had fully dissipated, leaving nothing more than the smell of fire and ash behind. Izuku turned around, and ran back to the beach. His mother hadn’t come to the school to pick him up, nor called while they were gone, meaning she either was dead or had done like everyone else and given up on him. 


It took a little over seven months, but he eventually managed to compile enough information from the library to learn how to make a welder, which lead to him knocking out pieces of cars with a sledgehammer, and then welding them together. The end result was two buses that still had all their sides and most of the roof still up, doors taken off, welded together for the main living area, with eight cars, four on each side, connected, one side for his sleeping area, the other acting as a kind of storage space for tools and other supplies. The cars were turned to where their side met either the front or the back of the bus, giving more easily accessed space than if he had simply left them from hood to trunk, though his sleeping space actually did have the cars connected by the hood, making it harder for anyone to spot them should they actually enter the makeshift house while he was sleeping. 




Izuku didn’t enroll for school at the start of the next year, choosing instead to continue with his self-education method and teaching himself everything he felt he needed to know to go to UA. It wasn’t hard to get a homeschooling license, especially since he got paid while helping people with random chores. No one seemed to realize he was homeless, and so he made an okay life, learning how to make things and eventually finding books in the library on different martial arts styles. It didn’t take long before he accidentally became a vigilante.


Izuku had taken to going to the more run-down parts of Musutafu, everything in those sections being cheaper than they were in the general populace. He always, without fail, wore a hood and a small face-mask to hide his age and appearance. Then he started noticing people getting assaulted in alleyways and kids getting snatched from their parents. The first crime he solved was an attempted kidnapping. He left the perpetrator tied and dangling from a light post while the family thanked him for saving their two kids.




He became Apparition, the vigilante that came out of nowhere, went nowhere, and always saved his target. Many people had tried to follow him home, but always, without fail, got lost in a trash heap. A few years later, thirteen year old Midoriya Izuku was a little above the average high-school student’s education level, had a home that, while it would never be the envy of the neighborhood, served every purpose he needed, and was a kick ass vigilante. He’d heard rumors of a man for the past few years building up, rumors that said he took and gave quirks as he chose. One thankful victim had told ‘Apparition’ about the man and told him to go there if he wanted a specific quirk. Izuku bowed to the victim, before vanishing onto the roofs, not even considering the words. He’d made it this far without a quirk, and he’d be damned if he used one now. 


He’d met Eraserhead on several occasions, and worked with him on three of those occasions, but he was not prepared for the Underground Hero to be waiting on him on a rooftop one night with food. He eyed the hero warily, not sure if he should accept the food. He’d been surviving fine on the scraps he found.


“It’s not laced with anything, Problem Child. We both know I can’t take you in for breaking the law anyways. Eat, you’re too skinny.” The hero huffed at the technically-is-but-not-a-vigilante in front of him. The kid was obviously severely underweight, and while one meal wouldn’t fix that, maybe he could gain the kid’s trust enough that he’d accept more things from him. He activated his quirk for a second one more time just to make sure, but he got the same result as always. This kid had no quirk. He carefully walked over and sat next to the kid, pulling out his own snack. “So, you look about middle school age. Where do you plan on going to high school at?” 


The boy tensed. “I wanted to go to Yuuei, but everyone said it’s impossible for someone like me. But, they would have said this was impossible for someone like me too, so I don’t know. What do you think, Eraserhead-san?”


“I think that quirkless people face too much discrimination. I think that it’s going to be hard as hell, but a quirkless person can do just as well as someone with a quirk. I think you already have more potential than all the classes I’ve had previously combined.” The hero placed his hand on the vigilante’s shoulder. “The quirk doesn’t make the hero, Apparition, the hero makes the quirk, or lack of one. There are plenty of heroes whose quirks are useless in hero work, but they are heroes anyways. Think about it, Big Shot’s quirk is literally knowing how to disassemble and reassemble electronics. Lunch Rush makes good food. Ectoplasm, while he can clone himself, has no legs. It’ll be hard, and you may have to make your way up from the General Education course like I did, but you can go to Yuuei, and more importantly, you can become a hero.” The Erasure Hero turned to see tears streaming down what little of Apparition’s face he could see beyond the mask. “No, kid, no, don’t, fuck.” His hands fluttered a bit, not knowing what to do with a crying kid. Usually he knew what he did to make kids cry, but this time he had no clue.


“It’s fine, you’re just the first person to tell me that.” 


“What? That you’ll have to work hard?” 


“That I can be a hero.”




At fourteen, shortly after sending Yuuei his application in the mail, Apparition got seriously injured while saving Present Mic from an ambush. He was joined in rescuing the vocal hero by Eraserhead, who it was a treat to see in daylight. Apparition disappeared before the two heroes could notice just how hurt he was, intent on reaching his home so he could stitch himself up in time. Doing parkour with a hole not only in your stomach but two more in an arm and a leg? Near impossible. It was hard enough that he didn’t take in the presence following him. He crashed through the bus door, moving as fast as he could to get to the medical side of the two buses, and immediately sitting down to try and stitch himself up, only to wake up moments later to find himself on the ground. The last thing he saw before he finally completely faded out was a pair of worried gray eyes and ragged black hair. 




Izuku finally came too to see white walls and a green curtain. He had no clue as to where he was, he’d never been in a hospital room with so many cots in it. He turned his head to the other side to see Eraserhead, his head pillowed in his arms on the side of the bed, sleeping. Izuku lazily reached up to brush at his eyes and hummed when he felt his hand touch skin… HIS MASK! He felt himself spiraling into a panic. He barely recognized when Eraserhead got up and started coaching him, bringing him down from the panic attack. “It’s okay kid, no one knows anything except that you got hurt by a villain. They know that you are a vigilante since you helped save Mic, but they haven’t been allowed in here, and Recovery Girl and I have been the only two to see you without your mask. They don’t even know your vigilante name. Recovery Girl didn’t even run any tests to find out who you are.” Eraserhead’s voice and reassurances finally brought him down enough that the hero felt safe enough to leave the kid alone for a minute to go get Recovery Girl. She’d healed a small amount of the injuries, but there was still some healing needed, especially since the kid had been too tired to allow for her to do much more than force the wounds loosely closed and bandage them.


Izuku watched the tired hero slip out of the room, glad that if anyone had to see a face he hadn’t shown to the public in a long time, it was Eraserhead. He glanced back to the door when it squeaked open, tiredly glaring at the skeletal-like man that slipped in. “You’re not supposed to be in here.” Izuku nearly growled. The man quickly spun around, staring at the kid that was supposed to be unconscious. 


“My boy!” The man half-bellowed, puffing up to reveal All-Might. “I was not aware that you were awake!”

“Probably because there are only two people allowed in here right now.” The young boy glared at the number one hero, too tired to be surprised by him being a living skeleton. Served him the fuck right. 


“Ah, yes, well. There was a very important matter I wished to discuss with you! You see, I am the eighth holder of One For All, a power that has been passed down for generations, from the start of quirks. I was in a fight with a villain about five years ago, and he managed to land a hit that destroyed my body, leaving me with no stomach and only one lung. This is all very hush-hush, as you may can realize, but I wish for you to be the ninth holder! I-“


“No.” The vigilante’s voice was bland, but still lashed out like a knife. “I don’t need your quirk.” 


“But, you see, your my last hope! I really-“


“Pass it on to someone else. I don’t want it.” He went to turn over, only to find himself suddenly pinned against the bed.


“I’m sorry it has to be this way, but this quirk really needs to go on so that he can be defeated.” All-Might quickly bit into his skin hard enough to draw blood, holding the dripping hand over  the greenette’s mouth. He tried yanking his head away, but the symbol of peace simply forced it to still and forced him to keep his mouth open while blood dribbled in. He tried to spit it out, neither of the pair noticed the door opening to reveal furious red eyes and a woman waving her syringe cane, but Izuku instinctively knew some of the blood had gone down his throat. 


Eraserhead’s voice was colder than a blackhole when he spoke, “What do you think you’re doing?”

Eraserhead hurried down the hall and headed straight to Nedzu’s office. He had no doubt that Recovery Girl was with the principal, one of the only people to know the full story, or as much as Aizawa knew, behind him bringing Apparition to the school to be healed. Nedzu chose to stay in his office, under the terms that as soon as Apparition was fully healed, he was to be brought to the principal for… whatever the creature had planned. 


He hurried along the hall, mentally ticking down the second minute since he’d left as the aged heroine ran behind him. His pace picked up when he heard thrashing sounds coming from the infirmary. Had the kid fallen asleep and gotten stuck in a nightmare? He snatched the door open, Chiyo on his heels, and felt his quirk flare against his will at the scene. All-Might was pinning his son vigilante friend to the bed, forcing… was that blood??? into the kid’s mouth. A feral snarl ripped its way out of Aizawa’s throat as he strode forward. “What do you think you’re doing?” His voice was freezing, similar to the tone he’d used when he found three drunken men surrounding a small girl. 


The number one hero looked up from where he seemed to be trying to force Apparition to swallow the blood. “Aizawa-san! I’ll be done momentarily!” 


The erasure hero strode forward, using his capture gear to rip the symbol of peace off the vigilante, moving as fast as he dared to the kid’s side. “Kid, are you okay?” He softly asked, eyes firmly on All-Might as he helped the boy sit up. 


Apparition choked and gagged, leaving Aizawa no idea what to do besides rub the kid’s back and hope it helped soothe him. “I swallowed some.” The boy’s voice was hoarse. “He forced me to swallow, I don’t want it, I said no, I don’t want it! Why now! After all this time…” Apparition delved into senseless muttering, leaving Aizawa to wonder what it was. He was certain that the kid was talking about more than blood. 


Recovery Girl gasped, looking at All-Might with a gaze torn between anger, disappointment, and betrayal. “You didn’t. ” Her voice was more broken than he’d ever heard it. 


All-Might turned his head. “I had too. There are people getting caught… They say that he is still alive. I won’t be able to fight him a second time, but someone has to carry on the legacy. Young Mirio refused-“ 


Recovery Girl shook her head. “Not like this. That power… It was intended for its host to be willing to play host, not forced to hold it.”


All-Might’s form pulled up. “I am growing tired of constantly being interrupted. I gave this young man the power because he is the best match I have managed to find. This isn’t the first time it has been forcibly given to someone! Mirio Toogata refused to accept it, and I need someone, anyone, who is even semi-compatible to take over the legacy. From what I’ve heard, this young man has already proven himself a hero! He may not have wanted the power at first, but I’m sure he’ll come to accept it, especially after his own quirk becomes more powerful!” 


Aizawa’s voice was a whip of malice. “And what happens to quirkiness people? People who don’t have a quirk to boost?” 


All-Might faltered for a minute. “It is nothing more than a stock-piling quirk mixed with an enhancer! The quirk will simply make him more powerful! It may have a mild backlash until he learns how to control it properly, but… He’ll be fine! Just look at how I turned out!”


Apparition finally calmed down enough for his words to be understandable. “Midoriya Izuku. I bet you don’t remember him, huh, All-Might? Five years ago, he was nine years old. You saved him from a villain. He thought you were the best thing ever and asked you if he could be a hero despite the fact that he was quirkless. You laughed it off and told him to ‘be realistic’ and ‘have obtainable goals.’ That day was the day he got the worst beating of his life. The day he came home to find a Burt out husk of a home. The day he lost his mother. The day his former best friend finally Guly turned his back on him. Y’know… Up to this day, only two people knew what happened to him- myself and Eraserhead.”


Aizawa froze. He’d known that the kid had no where to go, and he could guess as to how badly he’d been treated because of his lack of quirk, but he had no idea that it was this’d. Then All-Might opened his mouth. “That’s all good and well, my boy, but what does this have to do with our current situation?” 


“I am not your boy. I’d rather die.” The vigilante’s voice was even more harsh than before, almost as if he were about to cry, though Aizawa noticed that not a single tear had escaped. “If things had played out different… If you were a personI could rely on? Maybe I would have been beyond ecstatic to have finally garnered some of your attention. Now though? I’ve been a hero to people for years. I don’t need nor want your quirk. Take it back.” Midoriya Izuku’s voice was low, treating, and Aizawa reprised a shudder. He’d faced fully grown villains giving off less killing intent than what this kid was giving off right now. 


Aizawa pulled his phone out of his pocket, sending a message to Yamada. It didn’t take long for the voice hero to bust in like a loud, feathery whirlwind, grab fucking All-Might, and twirl out again, spouting about the teachers playing a game or some shit. “Apparition, would you prefer Recovery Girl heal you and you rest some more, or her heal you and you come meet the principal?” 




“So, All-Might! What’d ya do to piss off Shouta so badly?” Hizashi asked while skipping down the hall. 


The hero stoically walked for a few seconds before responding. “I did what was necessary,” was all the hero would offer. 


“Aww, come on man! Details! I need to know!” 


“It is a quirks-old secret, and is no longer mine to share. The rights are the young vigilante’s.” 


“Oh shit. You’re a dead man walking if you messed with Shouta’s kid.”


“Shouta’s kid?” 


“Yeah! Everyone here knows that his son is a quirkless vigilante! We just don’t know his name. Well, Nedzu and I do, and Recovery Girl, of course, but even we only know his vigilante name. We’re not allowed to have his birth name.” 


“Aizawa has a son.” 


“Yup! Talks about his latest achievements all the time! We just refer to them as Dadzawa and Sonkid.” 




“What else would we call him? Shouta only let a couple of us know his name. And up until today, Shouta was the only one that knew what he looked like! He kept the rest of us away from him, which was completely unfair! We all know exactly how important vigilante’s are to Underground heroes, so we really only arrest them if they’ve left a trail of deaths in their wake.” Present Mic skipped into the teachers lounge, which was surprisingly empty. “Since you can’t tell me what you did to ‘Kid,’ as Shouta calls him, did he tell you anything?”


All-Might stared at the vocal hero. “As a matter of fact, he told me about this quirkless kid I came into contact with a while back, named Midoriya Izuku, that asked me if he could be a hero.” 


“Oh! You said yes, right?” Mic shouted, then watched the hero’s face close off.


“Of course not. The kid thought he could be a quirkless hero.” 


Mic froze, no longer smiling. No wonder Shou kept us away from him. It must have taken him forever to gain the kid’s trust if he had been crushed so callously by the hero everyone looked up to. “What, exactly, did you say to Midoriya Izuku?” Yamada felt his blood freeze at the heroes words, and it quickly came to a boil. 


“I told him to be realistic, and left.” 


Mic shot a quirk text to Midnight.All-Might would later wake to find himself in quirk suppressant cuffs, tied to a chair in the teachers lounge, sans Aizawa and Yamada. 




Nedzu frowned, shocking the three adults in the room. It was rare, very, very rare, for Nedzu to frown. “This meeting has not gone as I had planned. Give me an hour, I know some people that may be able to help. I shall also begin the search for a new foundations of heroics instructor.” The principal offered a smile toApparition. “I understand your desire to rid yourself of the quirk as soon as possible. If Mirio-kun says no a second time, after seeing your story, I will see if there are any old friends that would be willing to take the quirk to the grave.” 


“How will Mirio-kun see my story? I was under the impression that his quirk allowed him to phase through solid objects?” 


“It does!I am going to have Nighteye and a few old friends work together! I will need you to consent to Nighteye and Mirio both experiencing our story, though, as well as the current occupants in this room.” 


Apparition considered the dog-bear-mouse, then slowly nodded. 


Forty-seven minutes later, the group was speeding to pick up the required people and escort them to Nighteye’s agency. Bubblegirl happily escorted the group in, cheerily chatting with Mirio as they walked. 


Nigheye stood in his office, tapping his foot. “What, exactly, is the purpose of this, Nedzu?”


“I do believe that this is easier seen than explained, as it pertains to very sensitive information. This is the only way we will learn several things, and I do believe that there is moment or two you yourself will have to witness to believe. Young Apparition here has already given his consent, do we have yours?” 


Nigheye scowled at the group. “I suppose so. If things are as bad as you made them out to be over the phone, I don’t really have a valid option.” 


“You could say no and we would leave, no questions asked. But Ido hope you help us.” Nedzu cordially smirked up at the slender hero. 


Nighteye sighed, though he was curious as to what was important enough that Nedzu of all… creatures? found it necessary to view a kid’s entire past. “Fine. I will assist you.” 


“Who all is going into the vision?” The friend that mentally connected people asked even as the other reversed Nighteye’s quirk so that he experienced theist, not the future. 


“Just Nighteye, Eraserhead, Present Mic, Le Million, Apparition, and myself.” 


The two women nodded, Tamatoko stepping forward to tap the afore mentioned people on the head. Nighteye took a deep breath, activated his quirk, and touched the young vigilante. 




“Kacchan!” Tears streamed down the poor boy’s face. “The doctor said I’m not gonna get a quirk. He said for me to give up!” 


They watched as the blond slowly turned around. “What? What about not getting a quirk?” 


“The doctor said I have an extra pinkie toe joint, so I’ll never get a quirk!” The boy sobbed. 


“So you really are a deck. Useless, quirkless, what’s next? You thinking’ you’re gonna be a hero?”


“Well, I mean, I can…” his voice trailed off as the boys standing there started smirking. The memory passed with him screaming. 


Three years muddled insults and injuries flew by, as well as in increasing distance between the boy and his mother. Most of the group found themselves concerned that the boy had spent the majority of his life in a state of dissociation. 


Everything snapped into focus, the not-yet vigilante standing in front of a couple of cowering kids, face emotionless as the same group as before surrounded him.The viewers were horror stuck as the kid allowed himself to be beaten in place of the other two kids. 


The scene abruptly shifted, and they found themselves running from the same group again , turning down an alley only to be grabbed by a villain. Fear flooded through them, quickly replaced by awe as All-Might saves them from the villain. Then despair as the hero coldly reflected them and left. They half-heartedly process the fact that Kacchan left rather than attack, though the overwhelming despair made it near impossible to do anything but curl into a ball. 


It was made worse when the boy returned to find his mother gone and his home burned down. The years passed in a blur of learning, crafting, building, working, and beginning his career as a not-vigilante. Then they met Eraserhead- not the first time, or the second, or even the forth or fifth time working with the pro. No, what mattered was the tired pro waiting for him atop a roof with food. Hope, fear, joy, so many emotions battled for dominance within them as Eraserhead told the boy his views on quirkless heroes. 


They were quickly jerked out of their reverie when that day’s events began, Apparition showing no concert to himself as he left in to protect Present Mic, and fled to his home. The world faded to black as they stared into dark gray eyes. 


The panic of waking without a man, and once again, Eraserhead was there to help. Then he was gone and All-Might was creeping into the infirmary, forcing his quirk onto the boy. They finally came out of the vision when they reached Nighteye touching Apparition. 


The room’s occupants, sans Apparition and Aizawa, dropped to the ground, the vigilante simply standing there, eyes emotionless. Nedzu’s friends were gone, and the group had no idea how long they’d been stuck in the past. Tears were streaming down Mirio and Yamada’s faces, Nedzu and Nighteye were frowning, deeply , and Aizawa had moved to stand beside Apparition with a match to his emotionless expression. 


“I must say, the one thing I am pleased with was Recovery Girl opting to remain at Yuuei. I dare say that none of are prepared for the murder spree she would begin.” Nedzu panted out, almost completely recovered from experiencing the tumuli past behind Midoriya Izuku and the added bonus of unexpectedly having to experience the boy’s own emotions in the moment in addition to their own. 


Nighteye hung his head in shame at the revelation of what his old friend had become after they went their separate ways. He cursed the fact that his visions only allowed him to see one person’s future, and not the aftereffects of decisions hastily made. If he had seen what would happen to the son he was not aware his sister had, perhaps he could have prevented something.
