What I've Done:
Chapter 1
Midoriya stood trembling, gripping at the hem of his shirt so tightly that his knuckles turned white from the pressure. He tried his best to keep his lip from wobbling but to no avail. Still, he refused to step aside no matter how afraid he was.
"Stop it! You're making him cry, Kacchan!" he insisted, keeping himself firmly between Katsuki and child that his ex-best friend turned bully had been harassing.
The blonde looked momentarily taken aback before his expression morphed into a sinister smirk, hands smoking with anticipation. "Quirkless Izuku…" he taunted, "What are you going to do about it?"
"I-If you don't leave him alone… I'll… I'll stop you myself!" Midoriya responded boldly. His internal dialogue was much different, however; he knew he was no match for Bakugo one on one, and he certainly couldn't handle him with his two followers there as well.
He dared to let his eyes flicker away for a moment, hoping to catch the attention of one of the teachers that were supervising their after-school care. There was a brief overlap in their gaze, his expression pleading for help.
The woman simply rolled her eyes to herself and turned to continue the conversation she was having with her coworker, leaving Izuku to suffer through whatever it was Bakugo was planning on doing. The blonde saw the boy's desperate attempt at assistance though, his sneer growing.
"What's the matter, Deku?" he scoffed, "I thought you were going to stop me yourself!"
Midoriya snapped his attention back to his opponent, knees cracking together repeatedly as he gulped. "I'm going to be a hero… I can do this!" he tried to tell himself, his tiny fists coming up to either attack or defend. "I won't let you hurt him!"
The two boys behind Bakugo activated their quirks as well, following their leader as he descended upon his prey. Izuku didn't last two seconds before he was knocked back by a small blast, his classmates' fists soon following as he flinched and curled in on himself to try and get away.
Tears poured from his tightly shut eyes as they finally got tired or bored and let him be, the blonde scoffing another insult out as he gave him one last kick. Midoriya whimpered as he untensed and lay on his back, gazing around.
The boy he'd defended had left sometime during the scuffle, and the teachers were still pretending to have not noticed him getting beat into the ground. It was heartbreaking to know that he was worth so little simply because of genetic variation that left him without a superpower… even a purposeless quirk would have somehow made him more valuable.
All men were not created equal.
Shigaraki was just a teenager when he saw Midoriya for the very first time. The boy was small and weak, his cheek blackened with soot that had been smeared over a large, swelling bruise. But those brilliant emerald eyes were determined despite how they oozed fat tears.
He watched with great amusement as the child picked himself back up after taking a terrible beating, the three bullies finally leaving him to nurse his many wounds. Even the child he'd protected had left him there alone.
Tomura found himself walking over to the whimpering boy, towering above his four-year-old body almost ominously. "Why did you do that?"
Midoriya almost hunched over, eyes darting around as he searched for a parent or teacher to help him once again, 'Stranger Danger' practically written all over his fearful face.
"Come on, kid, I asked you why you took a beating for someone who didn't even bother to give you a hand afterward. Are you stupid or something?"
Izuku's prior fears were quelled at the insult and he sniffed in roughly, balling up his tiny fists in anger. "I'm going to be a h-hero!" he stated, "and… and heroes never back down!"
Tomura tilted his head some at the declaration, finding it endearing and yet completely pitiful at the same time. He'd heard the little gang leader call this child quirkless so he knew that the kid was spouting hot air just so that he could keep clinging onto hope in what would no doubt be a pathetic existence.
"Where's your parents, kid? Don't they know it's not safe for little children to play alone?" Shigaraki questioned further. He remembered his own past, being left on the side of the street covered in blood as everybody passed him by; no hero had come to aid him either.
"Mom has to be at work right now and my dad… well… he hasn't been home for a while… My after-school teachers are just over there though." Midoriya explained, his expression falling into sadness once more as he tugged at the hem of his dirt covered shirt.
Shigaraki's chapped lips sneered into a pleased grin and he kneeled down, holding out a hand. "That's too bad. My name is Tomura, what's yours?"
Izuku looked at the appendage suspiciously, the warnings adults had told him still present in his mind but almost overtaken with his childish curiosity and inherently trusting nature. He bit his lower lip and ultimately gripped two of the elder man's fingers, shaking them hesitantly. "I'm Izuku."
"Well, Izuku… How about I take you to the bathroom to help you clean up. You wouldn't want your mom to get upset about all the stains, would you?"
Midoriya panicked a little at the thought and shook his head quickly, accepting the teen's offer. He kept hold of his fingers, arm stretched up high as he was led away from the playground. It didn't even register that the one walking with him was texting something out as fast as he could with his free hand.
Tomura was practically vibrating with excitement when the boy's oblivious caretakers failed to notice one of their charges being taken off the playground. He held open the door to the on-site bathrooms as he'd offered, his dark grin growing when Kurogiri's warp gate opened just after.
Before Izuku could even understand the situation enough to scream, he was shoved through, Shigaraki following right after and disappearing without a trace.
Midoriya woke up sometime later, his head hurting. He couldn't remember exactly what had happened, but he had a bad feeling. He opened his drowsy lids, absently taking in a room that he didn't recognize.
The walls were bare and plain looking, with no window in sight. There was a small, child-sized desk and chair, and a little dresser in the corner. He sat up slowly, hands running over the warm, soft comforter he'd been tucked under.
"H-hello?" he whimpered quietly, tears forming when he realized he'd been tricked. "M-mom?"
Despite how wobbly his legs felt, he quickly scampered out of the plush bed, running to the door and tugging as hard as he could. It rattled quietly, but refused to budge, every failed attempt causing his panic to rise.
Just as he was about to start wailing, the lock clicked and the door came rushing towards him, knocking him back to his behind. He grunted weakly, staring wide-eyed at the person who'd come in. It was Tomura, his expression one of utter satisfaction.
"You really shouldn't stand behind doors, Izuku. You could get hurt if the wrong person came through them."
"W-where am I?" he questioned, the stare he was receiving causing a chill to run up his spine.
"You're home now, Izuku. Come on, Master wants to see you!"
Midoriya shook his head quickly, curling in on himself as the tears he'd been forming came pouring out. This wasn't his home; he wanted his mom and All Might action figures… he wanted his own room and to gorge himself on Katsudon just like he usually did.
But Tomura simply picked up his small struggling form and easily carried him away, squeezing him a little too tightly so that he wouldn't accidentally drop him and injure him even more. "Quiet down." He insisted, giving him an impatient shake after a few moments.
Izuku refused, however, his frantic thrashing consistent despite his fear and surprising exhaustion after sleeping. It wasn't until Shigaraki got him into a dim-lit room that he froze, a bone-rattling chill shooting up his spine once more.
He stared wide-eyed at the one who was already there, his little mind unable to handle the amount of terror he was feeling. The man's body was large and well built, seemingly normal looking in almost every way. But the aura he gave off was monstrous—so intensely dark that even Midoriya could pick up on it.
"So, this is the child you brought back with you, Tomura." The man hummed, his voice smooth but haunting.
"Yes, Master," Shigaraki responded. He twisted Midoriya in his arms until he could hold him out like a prize, letting his feet dangle as he gripped him under his armpits. "I want to keep him."
"Oh?" All For One chuckled. "Whatever for?"
"He's just like I was, Master… He was alone and tormented and no one came to save him. Those hero bastards did nothing just like with me," he explained. "I'm going to show him how wrong he is about heroes and then I'm going to teach him everything I can; I just know he's the perfect person to aid me in building a new world once we destroy this one."
AfO smiled as he stood, walking over to examine the still silently balling child. He reached out a large hand and put it straight on Izuku's messed-hair, his expression becoming more amused. "This one doesn't have a quirk..."
"I know that!" The teen snapped. "That's why I brought him here to you… Give him one!"
The elder chuckled at his protégé's insistence, taking his time as he poked at Midoriya's almost frail yet baby fat-covered body. There was simply no way that the kid would survive if he forced a quirk on him at this stage, but, perhaps Shigaraki had a point about raising him to be on their side.
"It will take time, Tomura… His body simply isn't ready to receive something like that just yet, but I will indulge your desire to possess and nurture this boy. What's his name?"
"It's… Wait… Hey kid, that little brat that beat you up called you Deku but you said your name is Izuku, right? So, which is it?"
Midoriya was already hyperventilating to the point of near unconsciousness, his throat clamped shut in paralyzing fear. The only movements he could get any part of his body to do were quivering twitches every so often.
"We can just interchange them and see which he responds to once he's calmed down." AfO dismissed, fully aware of his presence effect on adults. It was almost sad how frightened he made little kids. "Take him back to his room and let him get settled… It will likely be a while before he accepts these new living arrangements."
Shigaraki's lips split ear to ear in deranged happiness, quickly hugging Midoriya's limp yet tense form back to his chest as he hurried off. "We're going to be great friends, Izuku-Deku-whatever your name is. Just you wait."
Inko was inconsolable as she frantically searched the playground with police, heroes, and Katsuki's parents. She screamed for Izuku to come back to her, to stop playing such a cruel game. But she and everyone else knew that it was just a feeble attempt to not have to face reality.
Eventually, the Pro Hero 'Serum' showed up. She was most popular among detectives since her quirk allowed her to get anyone she interrogated to tell her the whole truth. Inko dropped to her knees before her, pleading with her to find her baby.
It made Serum's throat tighten a little to see someone so completely distressed. She marched up to the daycare teachers first, eyeing them with clear disdain. "What is your last memory of Izuku Midoriya?" she asked one.
The woman gulped as she felt her insides twisting, sweat starting to bead at her temple. "I… He was being bullied by Katsuki Bakugo and two others… Over there, by the swing set."
"What did you do about it?" Serum pushed.
"N-nothing… We… I didn't break it up."
"You what?" Inko shrieked in horror. "That's why my son kept coming home with fresh bruises and burns? He said they were all accidents! How could you have let—"
"Mam, please, I can assure you that steps will be taken in regards to this grave miscarriage of justice, but right now that isn't our primary goal," Serum interjected gently. "You there! Yeah, you. What's your name?"
"Uh… I'm Officer Tsukauchi, Ms. Serum…" the man fumbled, rushing up to her side.
"Could you please escort Mrs. Midoriya over to the picnic tables and keep her company?"
The young officer nodded dutifully and began leading the almost defeated yet visibly enraged woman away, her glare aimed straight at the shame-filled teachers. Once everything resettled, Serum continued interviewing everyone that had been present, even children if their parents allowed it.
By the time All Might had arrived on the scene, she had a pretty good idea of what had happened. "Mr. All Might, sir," she greeted. "This is most definitely an abduction."
The large hero grimaced; those were always the hardest to deal with since they not only involved helpless children but were difficult to trace. "Any leads?"
"I was able to piece together a general description of the assailant, but, no one saw anything after he took Izuku Midoriya into the bathrooms. I suspect he or an accomplice had a wormhole or warp type quirk. Still, I can't understand what they would have wanted him for…"
"What do you mean?" Toshi asked.
The woman gestured for him to come closer, keeping her voice low so as not to let anyone other than him hear. "As you're well aware, most abductions of children center around their quirk abilities now, but, this child had none. Furthermore, everyone here describes him as rather plain looking… Perhaps he was just an easy target?"
All Might sighed heavily at the information; without a quirk and no obvious reason for why he was taken, it would be even harder to find evidence of him anywhere in the world. At least with extremely distinctive features or powers, someone might recognize them.
He turned to look over his shoulder at the boy's mother, watching as she sobbed onto the officer's shoulder with abandon. The two made eye contact, and Tsukauchi tightened his grip on the woman's shaking form… They weren't going to find him…
