Return of the Monster

Capitol Building, a week after the death of NFA

Eri convinced Kota to meet with the leaders of the rebellion to discuss a peace treaty. Kota is now the emperor of the empire was in his seat with his new advisors waiting for the leaders of the rebellion. Then Shinso, Inko, and Eri arrived to take their seats across from him. Kota with his mask muffling his voice, "I finally get to see the real leader of this silly rebellion."

Inko smiled, "We know who you are Humility, or should I call you Kota."

Kota glared at Eri which Eri looked away, "I prefer Humility, it is the name my former master gave to me."

Shinso said, "None for All is dead meaning you can't erase quirks…"

Kota chuckles, "My master passed on his quirk to me, I can still erase quirks like he did. I plan on finishing what he started, quirks caused all of this and I'm going to end these silly conflicts by ending quirks."

Eri glared, "You really aren't going to give up on this goal of his."

Kota nodded, "Eri, your quirk All for All as my master calls it, imagine if the entire world knew about it and my quirk. They will just kidnap us to experiment on us, people's thoughts on quirks would change, and they would want to take control of us for their gain…"

Eri said, "I know… but we will not reveal our quirks to the world. We can continue our lives like we original were doing. You can be that guy sitting next to me that I fell in love with and I can be that girl next to you that you fell in love with."

Then clapping was heard, they turned to see a pile of dead rebels and imperial guard with a green hair teen with a familiar oni mask. Eri in shock, "Izuku?"

Kota removing his mask, "Master?"

Inko in shock, "Izuku?"

Shinso got a closer look and saw the teen's yellow eyes which he jumped in front of him, "Who are you?!"

Insanity giggling, "Shinso, ole pal, it's me! The man of science and quirks!"

Kota, Eri, and Inko recognized the voice as Izuku but it had a different tone to it which Shinso in fear, "Insanity?"

Insanity took off his mask, "Correct! I have returned once again!"

Shinso asked, "How?"

Insanity looked at Kota, "Do you know why None for All doesn't approve of cloning?"

Kota said, "It's bad if you clone a being with multiple personalities."

Insanity clapped, "Exactly, I killed None for All and Izuku for complete control of this body. Now I have my own body and I will do what I always wanted that Izuku wouldn't let do."

Inko in horror, "Which is?"

Insanity smiled, "To make the entire world fear me and rule over the world as a god. With this new quirk made from None for All and All for All!"

The advisors went on the attack, but Insanity snapped his fingers and they turned to dust. Inko, Eri, and Kota got up and were on edge; Eri asked, "How did you get All for All?!"

Insanity giggled, "When you coughed out blood from making too many quirks, the royal doctor took that blood. He thought he was going to bring it to None for All, but he brought it to me. I call this new quirk All."

Then grey energy started surrounding Insanity, "Thank you Eri and Kota for helping me create the quirk of quirks, I will give you the chance to rule the world with me."

Eri got to a stance and surrounded by white energy, "Never…"

Kota was surrounded by black energy, "I will make sure you are dead for my master."

Inko looked at Insanity, "Are you sure Izuku isn't there?"

Insanity laughing, "I killed him for this new body, trust me on this one. He is dead…"

Inko pulled out a gun to shoot Insanity which Insanity still laughing while regenerating which Shinso, Eri, and Kota charged forward.

Insanity put out his hand with the bullets and the three couldn't move, Eri then made a quirk to help her move. Insanity went up to grab her and threw her to the ground causing a crater in the ground. Kota got out to punch Insanity's face, but Insanity grabbed his hand to crush his hand. Kota screamed in pain while Insanity laughed, "Was the best you got? Is this the best None for All's successor has? Disappointing!"

Insanity threw him to the side which Shinso made a 'Black Nuke' combo that Izuku would make then threw it at him. Insanity absorbed it which Shinso in shock, "How?! That is supposed to be unabsorbable."

Insanity looked at him, "I created Black Nuke and with All I can create a quirk to absorb it."

Eri got up to punch Insanity with as many quirks possible, "United Nations of…"

Insanity grabbed her fisted stopping her most powerful punch which Eri felt the pain of the quirks she created being erased. Insanity giggling, "Izuku had some much hope for you… in the end I was right, you are weak and unable to defeat me."

Then Kota jumped on Insanity to erase his quirks, but Insanity laughed as he created more quirks. Insanity threw both of them to the side which Shinso decided to use every quirk to the max to defeat Insanity, but Insanity grabbed his throat to begin erasing quirks. Shinso was in pain until Insanity's arm was disconnected. Inko cut off Insanity's arm which he laughed as his arm grew back in the blink of an eye, "You indeed are tough for a weak telekinesis quirk user. For a weak woman, you raised a weaker son!"

Inko was pissed and tried to punch his face but warp gate opened to make Inko punch herself. Insanity flew in the air, "You want to see a magic trick?"

Then Insanity dropped a ball of light and when it touched the ground a man appeared; the man started using multiple quirks. Insanity smiling, "I have created life, not a nomu, but an actual human being with multiple quirks. I will name this one Pride, because he is my pride and joy."

Eri, Kota, Inko, and Shinso were terrified by Insanity's power to create people from nothing. Then Insanity made six more with different varieties of quirks, Kota asked, "Let me guess, the seven sins."

Insanity giggled, "Good, I don't have to tell you."

The sins started attacking which then Aizawa and few heroes who have survived from the war with None for All came to help fight. Insanity looked at them like he was annoyed, "I can just make more but the Sins will kill every one of you."

Then Insanity had red energy coming from the ground which he started creating a sphere of the red energy. Aizawa tried to erase Insanity's quirk but nothing happened, Izuku looked at him, "Aizawa, don't you remember what created None for All and how it can't be erased and it also it protects the other quirks from being erased. All is made from All for All and None for All, it is the ultimate quirk."

Pride then activated his quirks to fight everyone, then Wrath did, and Envy was jealous then joined in. The only sin that didn't join was Greed which he stood there. Inanity came down to Greed, "What is wrong my child?"

Greed looked at him, "Nothing… I want to rule the world."

Insanity laughing, "You will, we will rule the world together. Now fight them!"

Greed ran over to fight which the Sins were destroying the battle which Inko said, "We have to leave!"

Kota saw his troops coming in with nomus, "Prefect!"

Kota warped to the commanders of the troops, "Release the nomus on them."

The commander asked, "On who?"

Kota pointed at the group as a whole, "All of them except for the white hair girl with the horn on her head."

The commander nodded which then they released two hundred nomus in total which Kota said, "I must go back to face Insanity, get your powerful guns aimed at him."

The commander nodded and got on his radio to give the orders while Kota flew back. Eri looked at Kota, "Thanks for helping us."

Kota knocked her out with one blow to the head, "Sorry, but we need to go."

Insanity laughed, "This is entertaining, I'll let you two go for now."

Kota then flew off which Eri which Shinso tried to follow but a nomu jumped in the air to attack him. Shinso was confused until he saw the rebels were being slaughtered by either a Sin or a nomu. The nomus have been proven to stand toe to toe with a Sin but the Sins were much smarter and stronger. Shinso killed nomu to then grab Inko and a few heroes out of the battle. Inko, Shinso, Mirko, Ryukyu, Hawks, and a few other heroes were warped to the base which Inko flew to a chair, "I can't believe it…"

Shinso said, "That's not Izuku, Insanity is worst and evil. He also played Izuku like a puppet."

Mirko said, "I can't believe the emperor also betrayed us like that, sending out nomus in an attempt to kill us and them.

Kota and Eri

Kota got back to the commander with Eri, "Open fire."

The commander nodded and told the troops to fire at the nomus, Sins, heroes and Insanity with the most powerful artillery. Insanity looked at them, "Child's play, you think guns like those will destroy me and my creations."

The barrage of artillery round came which fill the sky with black smoke until the commander called it off. Kota used his x-ray vision quirk to see if anyone survived which he saw that Insanity and his creations survived. Kota looked at the commander, "Keep firing until they are dead."

The commander nodded which Kota flew off with Eri, Insanity giggled, "I guess I will let them go, but I must create more children."

Then Insanity made a giant fortress from where he stood then he looked at the Sins, "Destroy their guns if you don't mind."

They nodded and ran to fight the soldiers which Insanity started created ten people with multiple quirk, "You ten will be known as 'The Ten Commandments'."

The ten nodded and accepted their names then Insanity started making more people then giving them names. He laughed as he was creating them, "I will destroy this world and make it anew, I am GOD!"

The Next Day

Eri woke up to find herself on a bed in a nice house, she came downstairs to find Kota making breakfast. Eri asked, "What happened?"

Kota sighed, "Tactical retreat, Insanity is beyond powerful… almost god-like."

Eri looked around, "Where are we?"

Kota said, "We are in a safe house in Seoul the former capital of South Korea. We need to come up with a plan to deal with Insanity and his army of artificial human."

Eri in shock, "We are not in Japan?!"

Kota looked at her, "That's correct."

Eri looked at him, "What happened to Inko, Shinso, and the others?"

Kota sighed, "From the report they somehow escaped by a miracle, got hit on the back of the head by one of the Sins."

Eri relaxed, "The artificial humans are stronger than the nomus, I assume."

Kota nodded, "Smarter and stronger, my soldiers couldn't do anything about them which we lost all of Tokyo and the surrounding area to Insanity in the last 12 hours."

Eri smiled, "We need to start working together on this."

Kota raised an eyebrow, "Where do you want to begin?"
