AN: And we are back with another chapter! Thank you so much for the support on these final chapters. In all honesty I believe there should be only about 2-3 chapters left to this story. IT's been a long time coming and I hope I can make it the best that I can. Also, warning, there is a bit of a spoiler from the manga, you have been warned. So without further adieu, let's just jump into it!

Growing

Class 1A's dorms were silent, the class were all sitting around in the lounge area. "Any word yet?" asked Todoroki walking into the dorms.

Momo shook her head, "No, the teachers won't tell us anything. Anything with your father?"

"He knows something but he refuses to say anything. Something about it being top secret." explained Todoroki. "What about Uraraka?"

"She's in Nezu's office right now." explained Mina.

"And Eri?" asked Todoroki.

The class all sighed. We then are taken to the hall outside of Nezu's office, "Why the fuck not!" Yelled Eri, her voice echoing throughout the halls.

Standing inside the office was All Might, Aizawa, Mirio, and Nezu behind his desk. Currently Ochaco was trying to hold back Eri, "Eri, calm down."

Balling her fist Eri turned to Ochaco, "But mom! We can go save him, but they won't let us!"

"As we explained before, the situation has turned extremely dangerous. If we were to go in blind there would be a significant amount of casualties." explained Nezu.

"You cowards. Fine, if you won't do anything I'll just go myself." Eri turned to leave but was stopped when Mirio put a hand on her shoulder.

"Sorry Eri, but you can't go." Eri's pupils narrowed as she slowly turned around.

Looking up, Eri's face was filled with bloodlust, "Let me go Mirio." Eri tried to move but found that Mirio had tightened his grip. "Are you going to get in my way?"

Mirio looked down at Eri, "You're not thinking straight right now Eri. You need to relax and think things over."

"Let me assure you I am thinking straight." With a quick motion Eri grabbed Mirio by the forearm and threw him over her shoulder.

Slamming against the floor Eri got on top of Mirio and popped her claws. The heroes flinched, "Izuku was made to kill All Might, I wonder if his daughter can do the same with his replacement."

The heroes were about to move in when Ochaco got up, "That's enough Eri, let him go."

Eri narrowed her eyes, but reluctantly retracted her claws. "Are you really taking their side right now mom? For all we know dad might be getting tortured."

Ochaco hung her head, "I know that. I want to save him just as much as you do. But we can't go in without a plan. The person who experimented on Izuku is working with a person called All For One. He's the one who's behind everything, but he's also the strongest villain in Japan, if not the world. I can almost guarantee they won't kill Izuku just yet, he's too valuable. So that gives us at least 3 days, we already lost one, that leaves us with 2."

Ochaco then turned to Nezu, "You better have something planned."

Nezu nodded, "I do, but if we want any hope of pulling it off we need Eri's help."

Eri sighed, "Fine, let's see what you got."

"We already know the location of where the doctor is. And if the doctor is there, we have reason to believe so is Shigaraki along with the rest of the villains are there as well. However it's like you said, Izuku is too valuable, they won't kill him yet until they get what they need." explained Nezu.

"But what would they want with Izuku?" asked Ochaco. "He lost his powers, the only thing inside him is the adamantium."

"In all honesty, we don't know why they would want him." Said Nezu. "They can already clone him, and the clones have his powers. It just doesn't make sense."

"I'm still not hearing anything about a plan." Said Eri, annoyed.

Nezu nodded, "Right, as we speak we are gathering heroes that may be strong enough to take on one of these clones, if not slow them down. We expect the villains to have several dozen if not more clones. We will attack the base in one massive wave forcing them to focus everything on defending. Once their main attack force is out, we'll send in a task force inside. Eri will be there since she will be the only one who will be able to guide us to him."

"What about Shigaraki and AFO?" Asked Ochaco.

"Mirio here will deal with them. He's the only one capable." Said All Might. "You see, young Mirio here has my quirk. I am able to pass it down to others like a torch, and with it he gains all past users abilities. He won't be an easy opponent to take down but I have faith in Mirio." Said All Might.

"I'll be joining Eri while we go in and look for Midoriya." Said Aizawa.

Eri nodded, "Good, I could use someone like you."

"I'm going as well." Said Ochaco.

"I'm sorry, but you aren't." Said Nezu.

Ochaco raised an eyebrow, "What? Why not?"

"For one you're not a hero yet. Or even have a healing power like Midoriya or Eri here. If something were to happen to you we would be held responsible." Explained Aizawa.

"That's bullshit! Izuku has risked his life to protect us, it's only fair I do the same." Said Ochaco, trying to change their mind.

"Actually, I agree with them." Said Eri, much to Ochaco's surprise.

Ochaco turned to Eri, "Eri, but I can help."

"I know you can mom, but if you get hurt or worse. What would dad think when he finds out you died trying to save him?" Asked Eri. Ochaco stayed silent, "Exactly, please just stay here and wait for him. I'll go rescue him for the both of us."

Ochaco didn't want to, she wanted to be there when they saved Izuku. But she also knew that even with her small healing power there was no way she would be able to keep up with clones of Izuku. Balling up her fist Ochaco reluctantly nodded, "Fine, but be careful. I don't want to lose the both of you."

Eri smirked, "Don't worry I won't go down easy. I'll get dad back and once I do we'll be a family again."

"Good, then get ready we attack on the third day. We will rescue Midoriya and take down Shigaraki once and for all." said Nezu, getting up from his chair. "But our first priority will be Midoriya's safety, everything else will come second."

With that insurance in hand Eri and Ochaco left the office with some hope. All Izuku had to do was hang on for just a bit longer, but in his weakened state could he?

With Izuku One Day Ago

Opening his eyes Izuku looked around to see he was in a familiar looking place. "Oh god…"

"Do you remember this place, Izuku?" asked the doctor through a glass pain.

Izuku hung his head, "I remember."

"This cell, it was where we first held you," said the doctor. "The place of your death and your rebirth. Tell me, does it bring back memories."

Izuku tried to lunge at the doctor but found his arms chained up against the wall. "Now now, you shouldn't be moving around so much. You're still weak after all."

"Why am I alive?" Asked Izuku.

The doctor smiled, "Instead of answering that why don't you answer me. Do you want to die?" Izuku stared at the doctor, "By your own actions it seems like you do. Coming here alone with no back up, in a weakened state, no healing powers, and your own body slowly dying from the inside out. Seems to me like you want to die."

"I don't. I'm dying anyway, so I thought why not go out doing the one thing I always wanted. Killing you." Said Izuku.

"I see, so revenge is it. If that's what you really wanted then you should have pulled the trigger faster. Now you're here, alone and forgotten. But don't worry we will have some use for you. However, once we are done with you, well, you know what happens to unwanted products. Once it's finished I will finally be known as more than just the man who created the beast." With that the doctor walked away from the glass. Izuku could do nothing but watch as he disappeared from his sight.

"I need to get out of here. Ochaco and the rest of the heroes will come here. I need to stop the doctor before it's too late." Said Izuku.

Walking down the hall the doctor then walked into another room similar to Izuku's. "Your last use Izuku is to make sure things go as planned."

On an operating table Shigaraki laid with tubes going into him. Beside him was then another body, one belonging to AFO. And off to the right side of the bed was a cauldron of boiling adamantium.

The doctor then turned, as he did rows of test tubes were seen lined up against the wall. Each tube had someone inside. "Izuku was a failure, the clones are only temporary, but with these I will make sure they are a masterpiece."

Two days had past as Izuku was now being subjugated to several more torture methods. The doctor was looking for something inside him but Izuku just didn't know what.

Normally Izuku would just heal within seconds but with his healing power gone, he was now at the mercy of the doctor. Every cut, every extraction, every jab of a needle came with excruciating pain.

Izuku remembered the pain of the first time when the doctor originally made him, but this was something else. Once the doctor was done with him for the day he had one of the clones of Izuku throw him back into his cell.

There he laid shivering on the cold cement floor as blood trailed down his open cuts. Izuku knew that something was going on, something big but with him inside the cage he couldn't find out what.

That is until the night of the second day, after another night of torment Izuku laid on the ground of his cell. Once he noticed that the clones were gone Izuku sprung into action. Knowing that there weren't any cameras in his cell, Izuku was free to do what he wanted. Walking over to the door Izuku found that he had to put in a pin from the outside to open it up. But he had a rough estimate as to where the lock was.

Touching the wall Izuku began to feel up and thinking back he guessed where he thought the lock would be and popped one of his claws.

With a SNIKT soundpiercing the wall, blood ran down Izuku's knuckle as the panel on the other side of the wall was destroyed. After a small buzzing sound was heard the door to Izuku's cell opened up.

Stepping out of the cell Izuku looked around, "Good, there's no one here. Time to find out what that doctor has planned."

Having spent so long in this building Izuku knew it well. Running around the halls and turning corners, Izuku made it to the doctor's main office.

Sneaking in he went towards his desk. Searching through it Izuku found a file called Project Warrior. Opening it up, Izuku's eyes widened, "N-No…if that happens he would be unstoppable."

Going through the other files Izuku came upon one called 'The Beast" This was the one about Izuku. "The clones are in a sort of evolutionary process. Once the doctor finds the singularity, whatever that means, it's over. Each clone will become stronger than I was."

"It's amazing isn't it?" Izuku turned around to find the doctor standing at the doorway. "An entire army of super regenerating clones, with claws that cut anything, and don't need food or sleep. And at the helm, my master with the powers of a god."

"I don't understand, why capture me? It isn't for the adamantium." said Izuku, putting down the file.

The doctor shook his head, "No, not that, I have more of that metal than I could ever dream. It's the clones, while the clones are almost perfect they aren't you. But you too have flaws, your emotions. I made the mistake of not lobotomising you, if I did that you would have been truly unstoppable."

"You still haven't answered my question. Why keep me alive?" Asked Izuku.

"Regardless of what I said in the past, you are special Izuku. You see, you quirkless individuals aren't as powerless as we thought you were. No, on the contrary, due to the lack of quirk your genetic code is quite flexible. It can easily be molded and adapt to environments quicker. But the sample has to be fresh in order to make the cloning process perfect. Unfortunately, you were granted a quirk, which tainted you. But now that you don't have any quirk, your cells are going back to the way they were. Perfect." Explained the doctor.

Izuku raised his claw and pressed it against his neck, "What if I kill myself right now. Will your work be complete then?"

The doctor smiled, "It won't but, we both know you want to kill me more than anything else."

Izuku pressed the claw deeper, "After everything you just said, do you really think I won't do it? If I die, the plan fails and my friends have a chance to live."

The doctor sighed, "I'm fully aware that the so-called heroes will be here any day now. But it matters not, once the master is done he will have all the power he needs to stop them. And with the help of the clones he'll rebuild this world from the ashes of the old one. One where he rules above everyone."

"Sorry, but I can't let that happen." Said Izuku. "But I can at least by them some time with my death." Izuku was in the motion of slashing his neck when out of nowhere he felt someone grab his arm stopping him.

"Sorry son, but it's already too late." Said the doctor. Looking at Izuku, he found that one of the clones had Izuku by the wrist.

Izuku looked directly into the clone's eyes, he could see no life behind them, not even a spark. "The others will stop you."

That's when the clone punched Izuku across the face, knocking him out. "No, no they won't."

Third Day, night fall

There was about 2 hours of sunlight left, and all was quiet in the forest. That is until the sound of engines roaring was heard. Making their way up the mountain was a whole convoy of pro heroes from across Japan making it up the mountain.

Leading the charge was Aizawa, Mirio, and Eri by their side. After hiking up another mile or so Eri put her arm out stopping everyone's advance. "What do you see?" Asked Aizawa.

"Not see, smell. I can smell dad, but there's something else, another scent attached to him." Said Eri. "It's like he isn't alive."

Mirio put on his goggles, "The clones."

Aizawa turned, "Everyone get ready!" The heroes all readied themselves, "How many?"

Eri sniffed the air, "10, but is that really it? Can 10 really stop this many heroes?"

As they waited for the 10 to appear Eri could feel something was off. She looked around but could see nothing, as her eyes scanned the area she finally put everything together. "They let us get this far, there had to be a reason. Unless…."

Looking up into the trees Eri was shocked to see green eyes looking at her. Followed by more appearing, "Shit! It's an ambush!" Eri yelled out as all at once every single clone popped their claws.

The SNIKT sound was heard echoing through the mountains. Soon every clone jumped from the trees and onto the heroes below. Eri quickly followed suit and popped her claws. If anyone had a chance of defeating the clones it would be her.

Blocking the initial attack of one clone she noticed something about the clone. 'Their claws, they're weaker. These aren't perfect clones, which means they die easier!'

Pushing one back Eri jumped into the air and slashed. Her claws dug into the clone's neck, but as she sliced the neck her claws stopped when they reached the bones. "Shit, even these guys have an adamantium skeleton."

The clone then grabbed Eri by the arm and flung her into the air. Eri gritted her teeth as the clone jumped up after her and stabbed her claws into her stomach.

Blood splattered across the forest floor as they landed onto the ground. Twisting it's claws the clone inflicted more damage, Eri screamed out in pain.

But as she was, Mirio appeared from underneath the ground, "Power!" Punching the clone across the face he sent it flying through several trees. "You alright?"

Eri got up as the wound on her stomach quickly healed, "I'll live. You got All Might's strength and phasing ability right?" Mirio nodded, "Good, phase into their heads and destroy the brain. That's the only way to stop them."

"You want me to kill?" Asked Mirio surprised.

"Can you defeat them without killing them? Any damage you do they'll just heal, aim for the brain. Look around you, you may be able to stop them but the others can't." warned Eri.

Mirio looked around to find the rest of the heroes being overwhelmed by the clones, some were even dying. "The fight just started and we are already losing people. Don't just stand there and finish them!" Yelled Eri as she stopped a clone's attack.

Frozen still on the battlefield Mirio was trying to take everything in. Should he not kill, but risk the lives of more people. Or should he give in and kill, possibly saving more lives.

But his thinking almost proved to be his undoing when a clone jumped at him. As he turned he could do nothing but stair as the clone's claws were inches away.

Fortunately for him, Eri appeared and pounced on its back. Digging her claws deeper Eri slammed the clone into the ground.

She then turned towards Mirio with a very angry expression on her face, "Get your head out of your ass!"

Jumping up she grabbed him by the costume, "If you want to help then do something. If you're just going to stand there like an idiot you can just fuck off. You may be the strongest one here but you don't even have a spine to stand on."

Pushing Mirio away, Eri went back to the clones, leaving the young hero to rethink his choices.

With Izuku

Still in his cell Izuku was forced to watch as the battlefield outside the bunker began to escalate. He watched as heroes died thanks to his clone brothers. "So how does it feel Izuku? To know that you helped build those things by existing?" Asked the doctor standing in front of the cell.

Izuku fell to his knees, "To know you were created to be nothing but a weapon. A killer. That's what you were born to be, that's what you will always be."

"No." Answered Izuku. "You're wrong, I was born to be something more than just a weapon. I've helped people with those powers."

The doctor laughed, "Is that what you call helping? You leave nothing but a trail of death and destruction everywhere you go. Face it Izuku, people die when they get close to you. You can't hide what you truly are, an animal."

Izuku got up and slammed the glass, "You want an animal, I'll show you one. Let me out and I'll show you what you helped create."

Unphased, the doctor smiled, "Let's not forget which one of us is on this side of the glass Izuku. Well it's been fun Izuku, but you no longer have any use for me."

Izuku's eyes widened, "You found it?"

Reaching into his pocket the doctor pulled out a syringe, filled with a red liquid substance. "Yes. Everything that made you special to me is all right here. Healing powers, enhanced senses, super strength, and natural talent. It's all right here. Everything that ever made you special all packed into one small syringe. And now that I have it, the rest of the army can become you, no, a better you. That means you no longer have any use, I'm afraid this is where your story ends."

Pushing a button on the outside panel a large buzzsaw appeared from the ceiling of the cell and lowered down towards Izuku.

It then began to rotate rapidly, before long it had now begun to buzz. Izuku tried to back away but the saw kept going after him.

Now pressed up against the wall of his cell Izuku knew this was the end. But just as the saw was cutting his skin the power to the facility went out, stopping the saw.

"What!? The power is out, but we should have our own power source here." Explained the doctor.

Izuku then began to laugh, "What's so funny?" Asked the doctor.

"They actually got inside, now that's something I would have never expected in my life." Said Izuku with a grin.

"Who is it? The heroes? They should be busy with the clones right now." Said the doctor.

"Worse," said Izuku. "It's my girlfriend."

Looking at Izuku confused, the doctor was suddenly struck by a metal pipe. The impact forced the doctor to his knees. "Who dares!"

"I do." Said a voice through the shadows. The sound of footsteps were heard when out of the light appeared Ochaco wearing her hero costume. "Now I'm going to say this once. Get the hell away from my man!"

The doctor had a look of horror on his face as he watched Ochaco take a step forward. "Don't come any closer!"

But as he yelled that out, Ochaco threw something at the doctor. Piercing his shoulder was a throwing knife, "That was for Eri."

The doctor grabbed the knife and pulled it out, "You bitch! I'll make you pay for this." With his good arm the doctor reached into his coat pocket and pulled out a small device. "All units fall back into the compound, we have an unwanted guest."

All of the clones outside all suddenly stopped what they were doing and turned towards the facility. Without saying a word the clones all began to run towards the facility. All the heroes were confused, "What the hell? Why are they retreating?" Asked Mirio.

Eri sniffed the air, "Oh no, there's no way."

"What's wrong Eri?" Asked Aizawa.

"It's mom, she's inside the base. I caught the faint scent of her inside." Explained Eri.

Aizawa's eyes widened, "She's what!? Damn it, I told her to stay put. Change of plans, you, Mirio, and I will go inside ourselves. The rest will catch up later." The two nodded their heads but as they ran through the forest Eri suddenly heard something.

"Look out!" She yelled out, reaching out and grabbing both Mirio and Aizawa by the collars and pulling them back.

As she did something hit the ground sending a shock wave throughout the forest. Mirio was able to keep himself up, and so did Eri thanks to her claws. But Aizawa had some trouble, the sheer impact was enough to level the nearby trees.

This resulted in Aizawa being blown away, but as luck would have it he managed to throw his capture weapon around Mirio and hold on.

As the dust settled and the wind stopped blowing Eri looked up to see something she never thought she would see. There in a crater of his own creation was Shigaraki, "We meet again, heroes." He said as his white hair blew in the wind.

Aizawa knew who it was but didn't at the same time, "That's Shigaraki, he looks so different."

"That's not all, he doesn't even smell like a human anymore. Whatever they did to him he's now become the most dangerous thing on this planet." Said Eri. Looking down at her hands Eri noticed that they were shaking. 'I-I'm shaking? Does that mean I'm scared? Every fiber of my body is telling me that I should run.'

"So this is Shigaraki, the one working for All For One? Asked Mirio.

Shigaraki laughed, "Well, technically no. But I see where you'd get confused. I'm no longer Shigaraki, I'd like for you to understand. I am All For One. This is now my new body."

"You were able to switch? How!? You're still locked up in Tartarus!" Said Aizawa.

"Ahh that, well it's not actually me. Inside I used a quirk that allowed me to make a clone out of myself." Explained AFO.

"But I used my quirk on you? It would have disabled your quirk and shown us the truth." Said Aizawa.

"Ahh yes, the man who can temporarily shut down quirks. Truly a powerful quirk, but you can't even begin to comprehend the amount I have. One said quirk gives me immunity to other quirks for 4 hours. Unfortunately, in the process of transferring bodies I have seen to have lost it." Explain AFO.

"But that means you can both die at the same time!" Yelled Eri as she jumped at the villain, claws out in front.

However as she was in mid air AFO raised his arm, this caused Eri to stop in mid air. "W-What's wrong with my body. I can't move it."

AFO began to laugh, "How naive of you little one. I have been alive for hundreds of years, seen more quirks, and taken more of them. Do you really think I don't have one that can control metal?"

Eri gritted her teeth, "Oh fuck."

AFO smiled, "Oh fuck indeed. You may not have an entire adamantium skeleton like your father. But you have the claws, claws that I help give you. And now, I want them back."

AFO waved his hand, as he did Eri felt her claws on her arm and feet begin to pull. Pain suddenly shot out throughout her body as AFO slowly began to rip the metal out of her body.

Eri screamed out in agonizing pain as blood began to run down the area where her claws came out. AFO smiled at the pain he was causing, Aizawa tried to use his quirk only to be blown away by a powerful gust of wind.

However just as the villain was about to yank them out a yell echoed throughout the forest. "SMASH!"

Appearing in front of the villain, Mirio had his arm pulled back. Throwing his fist forward he managed to connect with AFO's head.

The strike managed to send the villain back several meters. While simultaneously doubling the area that was flattened.

Thanks to that punch the quirk affecting Eri stopped. Now free from her shackles Eri fell to the ground. But before she could hit it a black tendril appeared and wrapped around her waist.

Gently putting her down was Mirio, "You good Eri?"

Eri nodded, "I'll heal."

"Good, then hurry up and do that. I get the feeling your mom and dad are going to need your help inside the base." Explained Mirio.

Standing up Eri's wounds quickly healed, her claws now felt sore but that didn't matter. "Alright, but make sure to take this guy down once and for all."

"Count on it." Said Mirio.

With insurance in hand Eri took off towards the facility, leaving Mirio to deal with AFO.

Inside the facility

"What did you do?" Asked Ochaco.

The doctor smiled, "I made sure you two will never get in the way of my research again!"

That's when Izuku could hear them, "They're coming."

"Have fun dealing with your brothers, Izuku." Said the doctor as the wall behind him bursted open. The hole in the wall was soon overrun by the clones but before they could even take one step inside, a wall of fire appeared.

"Sorry about that, but we can't let you get in their way." Izuku turned around and was stunned to find Todoroki behind them.

"Todoroki? How?" Asked Ochaco.

"Did you really believe we didn notice you leave?" Asked another person. That's when Mina appeared behind Todoroki. "You're not as stealthy as you think you are."

"Besides, it's not like anyone short of Midoriya and Eri can sneak by me." Said Jiro also appearing.

That's when one by one every student of class 1A appeared, all ready for a fight. "Now, are we done talking? Because I'm itching to get this party started!" Said Bakugo as explosions rippled in his hands.

The doctor took a step back in fear, "N-No! This can't be! You weren't supposed to show up! I need to leave, I need my dream to continue."

Everyone was surprised when the doctor turned towards the wall of fire and lifted his arm. As he did that the fire then suddenly began to split. This caused the clones to slowly trickle in. "You can't stop me anymore. No one can."

Passing through the split in the fire Izuku watched as the doctor left. "He's getting away!" He yelled as one of the clones jumped at him.

"We have to go after him!" Yelled Ochaco.

"We can't! There's too many clones, you'll never make it past them." Said Momo as she created a scythe.

That's when Izuku got an idea, "Ochaco, I need you to throw me!"

"Huh?" Said Ochaco, confused.

"Throw me towards the split. I need to go after him." Said Izuku as he stabbed into the head of a clone.

"But you'll be alone with him. You need back up!" Said Ochaco.

"I'll be fine, trust me." Said Izuku.

Seeing that look in Izuku's face worried Ochaco, she saw it before. It was one of a man who gave up, who was now willing to do whatever it takes to achieve his goal. With a heavy heart Ochaco reached out and touched Izuku's chest. Floating in the air Ochaco grabbed him by the arm, "You better come back to me."

Izuku smiled, "You know I will. I love you, Ochaco."

"I love you too, Izuku." Tightening her grip on him, Ochaco began to swing him around. With enough momentum behind her, she threw Izuku towards the gap.

Flying right by the clones all looked up to see him. They were about to give chase when ice blocked their path. "We have to keep them here." Said Ochaco. "Don't let a single one of them out of here. Got it?"

AN: DUN DUN DUN! The final showdown between the doctor and Izuku is about to begin. What will Izuku do, will Mirio be able to take down AFO, will Eri be able to make it in time to help? Find out next time, theories are welcomed, in the meantime stay safe!
