Welcome to my new story. This is one I had the idea for a long time.

Own Nothing but OCs

Talking

Thinking

Quirk

It was 6-year-old Izuku's actual first day of school and it had gone just like how every day of daycare and preschool went for him since he was declared quirkless when he was 4. He was mostly forgotten about and neglected. The kids with quirks even the weakest and useless were seen while Izuku wasn't.

'At least I wasn't bullied,' Izuku thought to himself as he walked home with his mother after she had picked him up from school. She was his real best friend, the only one to talk or care for him since his dad had left when Izuku was only a toddler.

"So, honey how was your first day?" Inko asked her son, hoping it was better than his other experiences in school.

"I was ignored like before," Izuku replied in a quiet voice.

"Oh honey, I am so sorry, I wish things were different I really do." She spoke to him softly as she pulled him into her side as she walked. They walked in silence after that when they got home Izuku went to his room to start the little homework he had gotten on his first day, while his mother had started dinner.

It was a quiet evening they shared. Inko tucked Izuku in like every night and wished him sweet dreams and told him she loved him. Izuku told her he loved her as well. Little did he know that would be the last time he would speak to her alive.

Izuku woke when he heard a crash. Fear slowly took hold as he slowly got out of bed and crept towards his door. He slowly opened and looked around. What he saw scared him so much he started shaking. There were three dark figures in the living room. Izuku was about to close his door when he saw his mother being dragged out by a fourth figure.

Izuku froze when he saw that. That is when one of the figures spoke, "Listen lady we don't want to hurt you. We just want your son and when we have him, we will leave neither of you needs to get hurt."

"Why do you want my baby?" Inko questioned close to tears.

"Don't know the man at the top said he wanted the boy and we were to get him without making a mess." The first figure responded.

"Please don't take my baby, he's all I have," Inko begged as her tears streamed down her face.

The first figure just sighed at that. He looked to one of the other two. "Go get the kid so we can leave." One of the two other figures heads to Izuku's door where he still was frozen stiff. The figure opened it and saw Izuku staring at him in fear.

"We ain't gonna hurt you kid as long as you follow directions ok?" the figure said as he bent down to Izuku's level.

"You aren't gonna hurt my mommy?" Izuku asked with a little bit of hope in his voice.

"No, we won't as long as you both do as we say." The man confirmed as grabbed Izuku and held him in his arms. He walked out of Izuku's room then, "Got the kid, let's go."

"Good see lady, we will be out of your hair so-," the first figure was cut off by the sound of Inko's head hitting the ground hard enough to crack the floor and crack her head wide open. She didn't stir.

The man other three men and Izuku froze at the sight and sound. The fourth who had originally had Inko just brushed off his hands.

"DUDE WHAT THE HELL?!" The first figure yelled at the fourth. "I told her we would just leave after we got the kid!"

"I'm cleaning up loose ends, who know it will take for them to search for the kid if she doesn't report it." The fourth said explaining his actions.

The one holding Izuku looked at him wondering what the boy's reaction was. He saw Izuku frozen not moving a single muscle as tears rolled down the boy's cheeks in waves at the sight of his dead mother. The figure holding Izuku just sighed at the sight.

"You are taking full responsibility for her death." The first said with authority.

"Yeah, yeah" the fourth brushed off his words.

With that they all turned to leave Izuku stared at his mother's dead body until she was out of sight. The second she was gone a hole appeared in Izuku's heart as the rest of his heart hardened. The men took him to a van where the one holding Izuku set him on the floor. Izuku still didn't move or make a sound. The other three men felt guilt as they made a kid watch his mother die, while the fourth dismissed the boy.

When they returned to the base the big man himself All for One stood there with the doctor who will oversee Izuku. The second he saw the boy he knew something went terribly wrong. The boy looked traumatized and completely unresponsive.

"What happened?" All for One coolly asked the men.

The apparent leader stepped forward and gave the rundown of the night events. All for One kept a calm visage but on the inside emotions began to rear their heads. He was many things, King of the Underworld, Symbol of Evil, collector of quirks, but he is not a liar. All for One has hated lying since he was a child. So, he swore never to lie. Not tell the whole story or telling half-truths perfectly fine, but to outright lie was something he despised. The doctor kept a passive face since it didn't concern him.

"I see," is the only thing All for One said. He then walked over to the broken boy. He crouched down to the boy's level. "Do you want justice for your mother?" he asked the boy softly.

Izuku slowly looked up and met All for One's eyes. "How?" was softly said not louder than a light whisper.

All for One formed a smirk at this, "By making his quirk the first one you gain." He told the boy while leaving out his plans for Izuku. See half-truths, telling the truth but not the whole story, still not lying. This will make the boy more willing for the experiments before they warped the boy's mind at least. He planned to make Izuku into a weapon with multiple quirks he knew not many were like Gigantomachia, but he will fix the death problem and gain an army of multi-quirk soldiers.

Izuku looked at him in shock, he was getting a quirk. This white-haired man was offering him the quirk of his mother's killer. He then looked to the figure who killed his mother. He was a big guy, roughly 6 feet tall and quite wide. He had light blue hair and grey eyes. He looked to have a strength quirk. The second Izuku saw his full appearance Izuku felt something he never had before, pure rage and hatred. His eyes narrowed and he grit his teeth as he nodded.

All for One's smirk turned into a full-blown grin. "Alright, it shall be done." With that, he turned and walked towards the fodder. The man tried to escape but All for One snapped his fingers and Gigantomachia appeared and grabbed the man and threw him to the ground and held him there. All for One strolled up to the man and reached out his right hand and placed it firmly on the man's head.

It took 5 seconds and the man howled the entire time. None of his comrades came to help because they all knew that he fucked up. After getting the quirk All for One turned and walked back to Izuku. He knelt before the boy again. "This quirk is a low-level strength enhancer that is allowed to enhance your strength by times 3." All for One explained as he placed his left hand on Izuku's head and transferred the quirk to the boy.

Izuku felt an intense burning sensation but didn't react too much and when the burning sensation disappeared, he felt a rush of power course through him. He slowly looked over his body and the only difference was the lesser amount of baby fat on his body, this showed off a small amount of muscle he didn't know he had.

He looked at All for one and bowed and thanked him with all his heart. All for One smiled at the boy before he asked the big question that was on his mind. "What do you want to with him now?" he asked as he pointed at the body of the unconscious man.

Izuku looked at the man and his rage came roaring back with a vengeance. He then looked back at All for One. "Can I deal with him?" Izuku asked trying to keep his wild emotions in check and failing.

All for One was curious what the boy meant but nodded. Izuku then pushed off the ground with his new quirk and shot towards the downed man. He let his emotions take over jumped when he got within range and aimed a dive kick right at the man's head. With his new quirk activated, and the force of gravity with his body weight, he crushed the man's head.

Izuku breathes deeply afterward, as he stared down out at the now dead man. "That was for my mom," was all Izuku said as he started walking towards All for One. The mentioned man had a smirk as he watched the boy. He looked that the other men.

"Clean up this mess and you are free to go." He told the men, who jumped into action and followed the orders.

He then looked down to Izuku who now stood in front of him with a blank face. All for One grinned at his. "Your name is Izuku right?" Izuku just nodded at the question. "Well, you can call me Sensei." Izuku nodded again. "You can call just call this man-," he was interrupted by Izuku.

"Doctor Ujiko?" Izuku asked surprised to see his old doctor.

"Ah that's right you have met before haven't you." All for One realized, "Yes this is him. He will be your personal doctor for what we have planned for you." All for One told Izuku, who just nodded.

21 years later (1 year before canon chapter 1)

Aizawa is better known as the hero Eraserhead was not having a good day. He had gotten up early because of the classes he taught at UA the most prestige's hero school in Japan. Then during the middle of the day both he, Present Mic, and Midnight were told by Nezu they are being added to a raid group that was being led by All Might. They both agreed even though Aizawa didn't want to.

When he, Mic, Midnight arrived at the raid meeting after school. They found All Might, Endeavor, Miruko, Best Jeanist, and Gran Torino.

That is when the detective leading the police force Naomasa Tsukauchi came forward and told the heroes the target of the raid. It is said that a high-level villain had a dangerous weapon that they were hoping to get to before they had a chance to use it. With that, they made strike teams. All Might, Endeavor, Miruko, Present Mic, and Gran Torino made the front line to take out as many as possible from the front while: Eraserhead, Midnight, and Best Jeanist came in from the back with stealth to find the weapon and disarm it before the villains have a chance to use it.

That was the game plan they had 3 hours to prepare before the raid began. Aizawa heard Tsukauchi ask All Might if he really believes it's him. All Might nodded and said that this had his stench all over it. Aizawa narrowed his eyes as he heard this as he left the room.

3 hours and 15 minutes later Aizawa had stealthily knocked another man unconscious as he, Midnight, and Best Jeanist snuck in through a back entrance of the bunker. They were slowly making progress as they heard the destruction caused by the other heroes a level up.

They found what they were looking for when they came upon the final room on the underground floor. Best Jeanist opened the door with some fabric just in case of traps. When the door opened, they found themselves in a large room about double the size of the UA cafeteria, with lab equipment to one side and computers and machinery next to it.

On the far side of the room was a large standing glass cylinder with multiple tubes connected to the top and bottom of the cylinder. Its diameter was about 5 feet and it was filled with a light green liquid. It had multiple monitors and different screens connected to the tube as well. It was inside the tube that shocked the heroes who had were just inside the room. Inside was quite a well-built man. He had a muscular build that showed he was way above the average man. But nothing over the top. He wasn't the tallest standing at 5'9 in height. He had black hair with emerald green highlights, that fell to his shoulders that looked quite fluffy. His face was had a solid jawline and four freckles on each cheek that made a diamond shape. The man was currently floating in the tube seeming to be asleep with a mask over his nose and mouth so he could breathe, he was only wearing a pair of shorts that only covered his groin area.

The stealth group was in shock. They were expecting a bomb of some kind, not a person.

Aizawa reached for his communicator, he opened into the raid channel that everyone in the raid was set to. "We've found the weapon," he stated.

"Good, can you deactivate the weapon?" The Tsukauchi asked.

"No, I don't think I can turn off a person," Aizawa replied with a deadpan.

"WHAT!" All Might shouted into the communicator. He was shocked because he knew whose base this was.

Five minutes later every hero was gathered in the room with Tsukauchi as forensic people started checking for evidence.

"Well, what do we with him?" Mic asked. Not sure what to do.

"Isn't it obvious we wake him up and arrest him?" Endeavor said with a huff. He wasn't seeing the problem. The man in the tube was obviously a villain that needed to be taken care of.

"Let's stop for a minute," Gran Torino said. "We don't know if he needs to be in there to live or what he would do once woken up. We need to be cautious about this."

"Yes, that the rational thing to do," stated Aizawa.

"They are correct. Did you find anything useful?" Tsukauchi called to the men at the computers.

"Only thing we found so far is what we believe the code name for the guy is." One tech responded.

"What is it?" asked Best Jeanist.

"They call him Weapon I"

"Like the letter?" Midnight asked.

"No roman numeral for 1," responded Tsukauchi as he looked over the screen.

"So, he is a weapon let's take him down now, so we don't have to worry about him." Endeavor said as he lit his hand on fire and launched an attack at the cylinder.

"No wait!" yelled Tsukauchi. But it was too late as the attack destroyed all the monitors and equipment around the cylinder. The cylinder was in perfect shape though. The slowly flowing liquid had stopped though. After seven seconds of nothing, the eyes of the now named Weapon I snapped open. Everyone could see the glowing green eyes he had.

The man took a moment to focus his eyes as he noticed the heroes and policemen his eyes narrowed, and bubbles started to appear around the mask. He started thrashing in the water getting angrier and more agitated. Soon he brought up a hand and three metal claws appeared. He punched forward and the claws pierced the glass, as he brought the other hand up and three claws popped out that hand as well. He pierced the glass with those as well as he then slashed in opposite directions breaking the glass in front of him.

He then pulled the mask off his face as he stepped out of the cylinder. He scanned the room while rolling his neck and cracking his back. He then started sniffing the air. He then burst forward with a roar straight for Endeavor who was unprepared for the attack. The Weapon slashed Endeavor across the chest then kicked him in the gut sending him flying back.

'fast' was everyone's thought about the man. He then turned and launched himself at the closed person who was Mirko. She was prepared and dodged the slashing claws. She aimed a kick for his chest and her foot just stopped when she hit him. She froze for a split second when she stopped. That is all the time the man needed to grab her leg and pull her towards him with so much force that it threw her off balance. He then let off her leg and grabbed her around the neck and slammed her to the ground.

The slam stunned her and before she could regain her bearings the man brought up his right hand and aimed his claws right for her chest and it was then that he was struck in his back by All Might the no-name weapon didn't so much as flinch for the hit which shocked everyone. The man let go of Miruko and kicked her away as he turned to stand face to face with All Might. He snarled and launched himself at the Symbol of Peace who thought he could take the claws when he was slashed across the arm he used to block and saw that his claws had almost cut to his bone. This shocked All Might who was unprepared for the second slash across his gut which had just missed his injury. He bent a little but was kicked in the head with enough force to make him stumble back a bit only to be rushed and slashed across the chest and left thigh and kicked again sending him across the room.

Before another attack could happen, Gran Torino shot forward and kick the weapon in the face. This kick did nothing as the snarling man slashed at him. Gran Torino quickly evaded and started bouncing around trying to confuse the man. The man kept trying to track the old hero as he kept getting free hits. Finally, the snarling man slowly stopped moving, and then when Gran Torino aimed for the back of the head the weapon spun around last second and slashed at the hero who tried to dodge and was cut deeply in this leg. The animalistic man then popped the set of claws away and punched the old man in the face and launched him across the room.

"YEAHHHHHHHH!" Mic yelled to the green-haired weapon. The force of the attack sent him skidding back holding his ears in pain.

"AHHHHH!" the clawed man howled out in pain. He then glared at Mic and growled while bringing his hands down and those watching blood liking from both his ears. He shot forward and aimed to decapitate the loud blonde. That is when he was wrapped up by Best Jeanist and Aizawa's capture weapon as the man activated his quirk. Many were shocked the claws didn't go away. Midnight tried to use her quirk, but the smoke didn't have any effect shocking the heroes and police even more. The human weapon snarled and try to break from the restraints they were around his arms so he couldn't claw at them. He started pulling them away when Endeavor stood and started charging one of his strongest flame attacks.

"Hold him still!" Endeavor roared out. "FLASH FLARE" right as he released the attack both Best Jeanist and Aizawa let go of the man. Who didn't have time to dodge. The flames hit him head-on and consumed him.

"AHHHHHHHH!" The man roared out in pain. He kept roaring until the flames died down. What everyone saw shocked them. He was still standing even though most of his whole body was covered in third-degree burns. He started snarling as the burned skins started to fall off and new muscle and flesh were being made at an incredibly fast pace. 10 seconds is all it took for all these wounds to heal. The heroes didn't know what to do, this wild man seemed to have multiple quirks and seemed to be a killing machine.

"The only one who did any good was Mic. If we could bind him again and have Mic go all out, we may be able to all-out we may be able to beat him." Aizawa said to the group who all nodded. They then rushed him hoping to distract him so he could be captured. All Might began a fistfight with the human weapon. The man was keeping up with All Might in turns of speed and was reacting fast enough to dodge or block most hits All Might sent. Any that did go through his guard, though were healed within seconds.

All Might lunged forward and got the human weapon into a grapple. "Eraser! Jeanist!" All Might yelled out when he got the man in a double armbar. The duo wrapped the snarling man again as Mic took a deep breath.

"YEEAAHHHHHHH!" He yelled out to the struggling man who howled in pain by the scream. His enhanced hearing was overloading and causing him great pain.

All Might decided to use is 100% to take the man down. He shot forward and aimed for the head. "Detroit Smash!" All Might called out as he hit the man with his full force. It struck the man while since he was so focused on his senses. It was a bit more than his resistance could take and rattled his brain and sent him flying. He was in a daze and started to stand again. All Might was in shock that his strongest hit hadn't finished the job.

The weapon stood up straight and tilted his head back and roared to the heavens. Then fell back and landed on his back out cold. The hit hadn't fractured his skull but rattled his brain quite a bit.

The heroes and police all sighed in relief. "Let's get him out of here and we can try to do forensics on the computers as well try to figure out who this man is," Tsukauchi said to the group who all agreed.

Two days later the human weapon slowly opened his eyes groaning in the process. He started to take in his surroundings and realized he didn't know where he was. He looked around and saw he was in a hospital. He just laid back down in the bed trying to clear away his headache. That is when a doctor walked through the door looking over a chart. When he glanced up, he saw an awake patient just staring at him.

The doctor jumped but quickly calmed down. "I see you are awake." The doctor said.

The green-haired man just looked at him and nodded.

"How do you feel?"

"…my head hurts."

The doctor just nodded. "Even with that kind of healing the blow to the head you took would knock anyone for a loop. We also had to have you drugged at 10 times the standard level to make sure you wouldn't wake up." The doctor informed him.

He made a grunt of acknowledgment and turned to look out the window. The doctor saw that as a dismissal and decided to do a quick check-up to make sure the man was ok. He started doing his checklist, the man allowed him to do so but growled when the doctor was near weak points. The doctor decided to explain what he was going to do to calm the man down. It did the trick if the doctor explained his process the man let it happen.

"Well you are all healed up but before you go there are some people with questions for you." The doctor informed his patient.

The man just grunted again and nodded. The doctor then excused himself when three people entered the room. It was detective Tsukauchi, All Might, and Gran Torino.

The man just gave each a once over and looked out the window again.

"Hello, my name is detective Tsukauchi, and is it okay if I asked you a few questions?" he asked the man whom they found in the base a few days back.

The man just nodded. So Tsukauchi decided to get on with his questions, activating his truth quirk to make sure the man didn't lie.

"Ok first question what is your name?"

The man just looked at Tsukauchi with a blank face, "Don't remember"

His answer caught everyone off guard. "What do you mean you don't remember your own name brat." Gran Torino questioned with annoyance.

"Like said shorty, I don't remember my name, I don't remember anything. Most things about my past is a blank." The man said with some annoyance in his tone as well.

Before Gran Torino could respond, Tsukauchi cut him off, "He isn't lying my quirk says he is telling the truth."

Both Gran Torino and All Might look between the two then.

"Do you remember anything?" Tsukauchi then asked.

"Yeah, some bits and pieces. I was an experiment, they tried to make me into a multi-quirk brain dead monster. They failed only about the brain-dead part. I have multiple quirks." He informed the group who were now in even greater shock. All Might and Gran Torino both thought of Gigantomachia.

"What are all they?" Tsukauchi asked hoping it wasn't too bad.

"Well, a few strength, speed, durability, and reflex quirks that each combined into one within me, or that is what the doctor said. Also, have all five of my senses have been enhanced to that of the best predators, because of a quirk called Apex Predator. That also gave me the ability to communicate with animals in the most basic sense. Then they gave me claws" he was then cut off by Tsukauchi.

"You mean the metal ones?"

"No, I was given bone claws first. Those were sharper than some steel first but that got changed later to the claws I have now."

"They coated the claws in metal?"

"Not just my claws my entire skeleton." The man revealed.

This shocked the two heroes and the detective to their very cores. "How, how are you still alive?" All Might asked in shock

"Yeah, that would be my original quirk. I was born with a very good healing factor which lets me heal really fast as well as make me immune to poisons and diseases as well." He explained.

"Do you know what kind of metal?" Tsukauchi asked.

"It is something they called a Vibranium steel alloy."

"Vibranium! That is one of the most sought-after metals in the world."

"Well, that is what I was told they coated my skeleton in."

That is when Tsukauchi got a phone call and stepped out of the room. Leaving the mystery man alone with the two heroes.

"Do you know experimented on you?" All Might asked.

"Probably did at one point. But not anymore. I believe they fucked with my head too much to make me loyal to their cause, whatever it was. Say either wouldn't happen to have a smoke I could bum off one of you? He asked.

"Sorry but we don't"

"Damn can't blame a man for trying" Then the man said as he leaned back in the bed.

"How is it that you can't remember your past but those facts about your abilities?" Gran Torino interrogated.

The man just looked at him, "A weapon doesn't need to know its name, but it needs to know what its abilities it has."

This made both men gain a thoughtful expression. Gran Torino nodded at that and relaxed a bit in his chair. While All Might fidgeted at the sheer awkwardness in the room.

That is when Tsukauchi came back in with a small smile on his face. He looked to the man on the bed. "We got through the lowest level of defenses on the computer from the lab. We know who you are now."

The man looked at him and raised just one eyebrow.

"Your name is Izuku Midoriya, you went missing the night your mother died 21 years ago. You haven't been seen since."

This caught the attention of the other three in the room the heroes turned to look at him wondering what his reaction would be.

The now named Izuku just looked at the group. "I don't remember any of that night you speak of. But thank you for telling me my name." You wouldn't happen to know how old I am?"

Tsukauchi smiled at that, "You are 27 turnings 28 on July 7 in about 4 months."

Izuku just nodded and thanked the man again.

"So, what's going to happen to me?"

"I can answer that four you," a fourth jovial voice said from the doorway. The group turned and saw a white Chimera with a business suit missing the jacket and had a scar over his right eye.

Izuku took one look at the animal and bluntly stated, "Who in the h-e double fuck are you?" causing the animal in question to laugh quite loudly at the wording of the question.

"Yes, who am I am I a bear, a mouse? More importantly, I am the principal of UA high school.

"Is that supposed to impress me?"

"Well UA is the number one hero school in Japan. And the place most of the top heroes attended. Even the number one hero right here All Might."

Izuku looked to All Might and stared for a moment. "Ok, I can see why he is number one. He is expelling power and my instincts say he is dangerous."

"Well you need to go somewhere, and I don't believe jail would be the right place. And I have seen the footage and read the reports of the fight you put up. After we intergrade you back into society, I would like to make you a teacher of my school after we get you a hero license."

"You seriously want me to be a hero? I may not remember much but I know I have killed before, that is what a weapon does."

"Yes, but you are a victim who was kidnapped and experimented on since you were a child. I believe you deserve a chance to help others as well."

Izuku just looked at the group. "Ugh, fine but I need some smokes and some booze."

"What you do in your free time is your choice. And you can smoke during breaks of school but no drinking until after school hours."

"Deal."

"Well Mr. Midoriya, welcome to your hero academia."

Yea new story and I am really liking this one.
