Chapter 1: A simple boy that can kill everyone and everything.

(xx - years ago)

In a basic house, inside a basic room, there was a baby in a baby crib, looking at the ceiling with classic child wonder. A woman was observing him with happiness, clearly being his mom. She giggled as the child waved at nothing, making some cute sounds.

"Hiiiii." the mom waved back "How are you today?"

The baby remained silent, as he still waved his arm at nothing.

"Hoooooney!" a man said from another room "Can you come here for a second?"

"Sure!" she then approached the child's face "Be right back!" she whispered at him as he continued to move his hand in the air.

"What is it?" the woman asked as she went to the living room, where her husband was staring at the ceiling, dumbfounded.

"Huuuuuh." the man mumbled, pointing upwards.

The mom looked up and immediately had the same reaction as her husband. As they saw a crayon levitating and drawing lines in the roof. All following the same motion the baby was making with his hand.


(xx - years ago - In a kitchen)

A young boy with black hair and yellow eyes was poking the single small horn he had on his forehead on his left side.

"Quit poking it, Yusuke." the mom asked her now grown-up son "You are going to hurt your finger."

"Okay- Don't boss me around!"

PLAFF!*

As Yusuke shouted, the pie he made with his mom suddenly hit her in the face. He looked at the scene with content and his eyes somehow changed to a red color.

The woman pulled the mixture out of her face and looked sternly at her son.

"Yusuke!"

Her scream startled the boy, and his eyes returned to normal. He now looked confused and scared.

"I-I-I didn't-"

"Don't lie to me!? Go to your room!"

"But I-"

"Go to your room, NOW!" the mom screamed, her voice becoming unnaturally deep.

Yusuke cried and flew to his room with his powers, slamming the door with unrestrained use of his telekinesis. Once alone, he sat at his door and cried.

"Would you quit with the whining!?"

Yusuke's eyes widened, and he looked around, scared by the unfamiliar voice and trying to see where it came from. But he was alone in the room.

"Hey, knucklehead! I am right here!" With the new shout, Yusuke slowly turned his head around and saw a girl with red hair and eyes on two pigtails glaring at him "Now zip it!"

"AAAAAAAAH!"

As Yusuke screamed in fear, the windows of the house exploded and sent glass shards far away.


(xx - years ago - In a museum)

"Everybody move!" a guard shouted as people ran behind him "Jesus, can somebody call a Pro!"

In front of him, you could see all things that would be impossible to see in real life, even with the advent of Quirks. Giant dinosaur fossils were walking and roaring like they were alive, paintings coming to life and jumping out of their frames while releasing a lot of paint in the ground, statues screaming for help as they couldn't move, and abstract art pieces continuously changing in size and shape. To top it all, Yusuke was riding a T-Rex fossil like it was a horse.

"Yiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii Haaaaaaaaaaa! Let's go!" he shouted, clearly enjoying himself, despite the apparent danger of the situation. His hair somehow changed to a curly navy blue one.

"Yusuke, my son, please get out of here!" the mom screamed. She was now holding another small baby in her hand.

"I am not Yusuke! I am the fearless cowboy Johnathan Havoc!" Yusuke exclaimed, raising a plastic gun to the sky "Pew! Pew!"

"Listen here, young man!" a man dressed in an elaborated outfit, clearly a hero, exclaimed "Obey your mom and get down here! This is dangerous!"

"John Havoc obeys to no one! If people say that he needs to get down-" as 'Yusuke' spoke, he jumped out the T-Rex head.

"Yusuke!" his mom cried, holding the other baby even tighter.

"Shit! Hang on!" the hero jumped into action.

"-HE GOES EVEN HIGHEEEER!" with a shout, 'Yusuke' body transformed into a bird-human hybrid creature with wings for arms and green hair.

"What?" the hero questioned, seeing the bizarre transformation in front of him.

As the birdman kept flying in circles and imitating bird sounds, the living things in the museum suddenly stopped. The fossils all crumbled, the statues locked in their screaming position, and the living ink paintings became just ink on the floor.

"What in the world?" the hero asked, dumbfounded.

As 'Yusuke' flew inside the museum, his shadow for a brief second changed to the shadow of a regular tall man, before reverting to his regular bird creature one.


(xx - years ago - In a school)

"Mr.¨&+}`^-•!" an adult shouted at Yusuke, who was sitting in a classroom.

The boy jumped in surprise as his classmates laughed at the scene. Their laughs made Yusuke really uncomfortable.

"W-What?" he asked. His head was shaking unnaturally and his left eye twitched a lot.

This made the other kids laugh even more, and their teacher got even angrier as a result, clenching his ruler with a lot of strength, almost breaking it in two.

"Don't play the fool! You were spacing out and mumbling alone again!" the teacher slammed the ruler on his table, breaking it "I know brats like you think that just because they have a good Quirk they can ignore school! Well, you can't!"

"I-I know! I'm sorry sensei, I was just-" before Yusuke could explain, he started to violently shake.

His body changed. The horn on his head became thinner but longer, his black hair became blonde and in a self-made ponytail, his eyes became blue and he grew up some inches. All while making disturbing inhumane noises, to the horror of everyone present in the room.

"What in the world!? Stop with this Mr-"

As 'Yusuke' threw what seemed like white clay from his hand directly at his teacher's throat, he never finished his sentence. The man choked as the clay somehow moved on its own inside his throat. 'Yusuke' stared at him with a sinister smile while showing the palm of his hands, who now had MOUTHS on it, to the choking teacher.

"I was just thinking about doing this to you, hm!" 'Yusuke' spoke with an entirely different voice.

He then placed his hands together and gained a look of sick excitement on his face.

"Katsu!"

After the blonde shout, the clay on the professor's throat literally exploded, and the blast was big enough to cover his entire face with fire.

The kids all screamed and cried with the scene, and desperately ran away from the class, while 'Yusuke' just stayed there, looking at the teacher, chuckling.

"This, this is art." he said before his body turned back to 'regular' Yusuke.

Yusuke blinked twice, not understanding what just happened until he saw his teacher's face, or what remained of it, and properly puked and cried.


(xx - years ago - In a hospital)

A hospital is quiet and comforting, designed to take care of the sick and injured with maximum care.

"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!"

Unfortunately, that wasn't the case for this hospital right now.

As the high-pitched scream continued to grow in intensity with every minute that passed, the whole hospital trembled. The tiles on the floor cracked, the drinking fountains burst, and the water on them fell upwards. Every single door had their shapes changed; the lights changed colors to a dark gray and grew and decrease in intensity all the time. All the staff of the hospital was in an even worse state than the place itself. They were partially turned into stones, others were on fire, there was a poor soul that got merged to the walls and was clearly agonizing, and there were other medics and nurses that had many painful deformations on their bodies.

Those weird deformation on the hospital were all over the place, but they got stronger and stronger as they approached a certain room, the room where the louder screams originated. Inside the room, an eight-year-old Yusuke was in the bed, holding his head in agony while jolting on his hospital bed.

"AAAAAAAAAAAAAAH! STOP IT! STOP IT! MAKE IT STOP PLEAAAAASE!" Yusuke screamed in a way he never imagined he could scream, although his voice looked like the voice of many people together somehow.

His face then changed to a red monster, and he made an inhuman roar as he crushed the side of his bed with his bare hands by clenching it. He then changed to a scaly dragon, a skull, the girl with pigtails, a gray mouthless creature, and many others. All while screaming.

"HOW DARE THEY!?"

"LET THEM BURN!"

"WE NEED TO LEAVE!"

"******************!"

"SOMEBODY HELP ME!"

"I WANT TO LEAAAAAAAAAVE!"

"GIVE ME MONEY!"

"PREPARE MY SHIP!"

"GYAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!"

As the many voices shouted at once in the mess that was Yusuke's face right now, a single doctor that somehow remained intact after all this chaos was hiding behind a table.

"Y-Yusuke! Please try to calm down! It was only a medicine!"

"SHUT UP!" all the voices exclaimed at once, sending a shock wave at the man.

As the man flew out of the hospital, destroying many walls and a lot of his bones in the process, Yusuke panicked again and he held his head while crying.

"He was right! We just need to calm down!"

"Idiot! We can't trust any of them!"

"We should kill all of them!"

"We will kill no one!"

"What did you say, bitch?!"

"Let's all calm down! Yusuke is suffering here!"

"***************&&&&&&&&&!"

"All of you... QUIET DOWN!" Yusuke shouted, making the room around him crumble to dust, along with all the poor souls that were unlucky enough to be in the hospital and close to it. In the remains of the hospital, Yusuke now breathed heavily and looked at his hands in horror. After a while, sirens and helicopters could be heard approaching the disaster zone, with Pro-Heroes also showing up to see what happened to the hospital. Yusuke remained still, shaking in horror while jolting his head unnaturally.

"Hey, kid." a hero approached Yusuke, who backed down after seeing the man enter the crater "Easy there. I am not here to hurt you. I am a good guy, everyone that came here is a good guy." he explained, slowly approaching him "Now, would you please explain to us if you know what happened here?"

"I-I-I..." Yusuke tried to speak, but tears covered his voice "I am... a mo-monster."

"What? No, you are not. Why are you saying this?"

"Because my mom told me that, and- THEY ARE ASSHOLES! Don't say that! Shut up, idiots! GRAAAAAAAAAAAAAAAH!"

As Yusuke said random things and his face transformed with each new sentence, the pro hero gulped and pressed a button on his communicator.

"Hello, I think we have a problem here."


(Present-day - Unknown location)

"~Happy Birthday to yooooou. Happy Birthday to yoooooooooou. Happy Birthday to Yusuke! Happy Birthday to yoooooooou~" a nurse sang to a teenage Yusuke while holding a small cupcake with a single candle on it.

As a teenager, he looked really pale and thin and his hair got longer, almost reaching his waist. His yellow eyes looked almost dead. The horn on his head grew a bit, but it didn't look exactly healthy, and he had a bored expression on his face. His attire was also unusual, looking like the ragged clothes of an apprehended criminal. He even had a thick necklace on his neck resembling a metal chain.

"Come on, Yusuke. This is your birthday! Lighten up the mood a little! Here, blow up your candle!"

Yusuke then raised his hand.

"Wait!" the nurse suddenly shook her hands to stop the boy "I mean, with air! Not with your... you know?"

Yusuke then slowly lowered his hand and breathed deeply. With a weak blow, he made the flame on the candle shake a little.

"Uuuuuuuuuuuuuh, please do a bit stronger." the nursed asked, trying to remain patient.

Yusuke inhaled deeply.

"But not-"

Yusuke's face quickly became that of a bearded old man and he blew the candle with enough strength to destroy the cupcake, the candle, and send the poor nurse to the wall.

"-with... so... much... strength." she mumbled, before fainting onto the ground.

Yusuke looked at the fallen woman for a while, feeling apathetic about her situation, although she looked injured. He simply got off his chair, approached her, kneeled, and whispered:

"Sorry." with a weak voice.

Yusuke heard an alarm sound behind him. A giant metal door opened, revealing a bunch of paramedics and a scientist. As the paramedics quickly went to examine the nurse on the ground, the scientist went to Yusuke and looked at him with a disappointed glare.

"Yusuke, what did I tell you before?"

"Never use your powers unless required by you." he answered, looking at the ground embarrassed.

"So why did you use it now?"

"Because they- I wanted."

"No." the scientist placed a hand on the boy's shoulder, making him look at the elder man "THEY wanted it, not you. You are a good boy who would never do this by your own choice, but those... demons on your head are influencing you to do the wrong. All we have to do is make you control them." he explained with a warm smile.

"And then I will go back to my parents? To go to school? To be a hero?"

The scientist passed his hand on the boy's long hair gently.

"Yes, yes, you will. Once we are done, you will start your training to become the strongest hero on the planet. But you have to effort yourself. Will you?"

Yusuke flinched at the mention of training and he rubbed his right arm slightly, but he quickly placed a smile on his face.

"I will!" he happily declared, smiling for the first time that day "You can count on me, Dr. Hayato!"

"Good, now go to your room. You will have training in an hour."

"Right!" Yusuke said, running towards the exit.

As the boy left the room, the old man's smile immediately dropped, and he sighed.

"Get rid of her." he ordered, coldly

"Get rid of her? What do you-"

"Throw her away! In a trash compactor, in the sewer, anywhere! Just make sure no one can track her down to us!" Hayato shouted "God, this whole stupid birthday thing was a mistake. I should never have allowed Yusuke to do anything other than train his powers."

"Uuuuuuuuuuuuuh. Dr. Hayato, don't you think you are being too cruel to the boy?" one paramedic asked.

As he asked that question, the other paramedics flinched and stared at him. Hayato remained still, not looking at the one that asked.

"Come again?" Hayato asked.

"I mean... you keep saying things about making him reunite with his parents, making him go back to school, but you know that-"

*BANG!*

Dr. Hayato didn't waste a second. He shot the paramedic in the face with his Quirk that allowed him to blast his nails like bullets. As the medic dropped to the ground, lifeless, the others stared at Hayato in shock, staring at his furious eyes.

"Listen here, all of you." he removed his glasses and glared at all of them intensely "That boy is not a human. He is a freak of nature, the apex of the evolution of quirks, hindered back by mental disease. The Hero Public Safety Commission wanted an invincible villain killing machine to replace All-Might after he retired, and I promised them that. And what happened last week?"

"All-Might... retired." one paramedic answered, scared and sad.

"Yes. This means that the Commission was all over me to deliver them the perfect hero. Now tell me-" he then picked one medic and looked at him right in the eyes "DOES THAT ABOMINATION LOOKS LIKE THE NEXT ALL-MIGHT TO YOU!? DOES HE!?"

"N-No."

"LOUDER!"

"NO, HE DOESN'T!"

"Exactly!" Hayato then threw the medic to the ground "Which is why we need to speed up the process! No more distractions! We spend six years with him and we are finally seeing progress! We can't stop! So get these two pieces of garbage out of my face and get back to work!"

"Yes, sir!" the medics exclaimed.


(Later)

"Attention! We will begin the simulation in the test room now! Everyone in your positions!" Dr. Hayato said in a microphone inside a control room.

Hayato and the other scientists could see Yusuke inside a large room with metal walls through a window from that control room. He was meditating there, levitating on the air and using a weird metal device on his head. The scientists all prepared the test room with maximum care. As they inserted such commands into their computers, the test room changed. Weapons and some robots appeared on it in large quantities.

"Dr. Hayato." a scientist entered the control room suddenly "There is a visitor from the Commission to see you."

"What? Who?"

"Me." the guest said, entering the room with not much ceremony, branding his huge scarlet wings in the place.

"H-Hawks!" Hayato exclaimed, losing a bit of his composure "I-I wasn't expecting to see you here!"

"Neither was I expecting to come, but the commission told me to see your progress on their 'next best hero' project? Whatever this is."

Hayato gulped and adjusted his tie.

"Oh, you don't know about it?"

"I just said that I don't know. Now spit it up." Hawks said impatiently.

"R-Right." Hayato coughed a little to recompose himself. He then pressed a button on the control room.

"Attention Yusuke! We have a very special guest here today! So make sure to do extra-good today!"

Yusuke turned his head towards the control room and looked at Hawks. Which ended up with one of them taking some steps backward and almost falling to the ground.

"What in the world?" Hawks asked, seeing the skinny teenager "What is the meaning of this!?"

"Huh? This is Yusuke. He is our project." Hayato said with a terrifying calm.

"He is a kid!" Hawks exclaimed. "Do you even have permission to do this with him?"

"Of course I have. The commission has a lot of influence. You out of all people should know this." Hayato explained, chuckling.

Hawks clenched his fists in anger, but said nothing.

"Just see him. You will understand why we are doing this in a minute. I assure you it is for the greater good." Hayato stated, seriously, "Prepare yourself, Yusuke." he announced on the communicator.

Yusuke gulped, shaking his hand a little. His left eye changed to a red color and scarlet lines appeared on the left side of his hair.

"Don't worry. Everything will be fine, it won't be like the other times, trust us." Yusuke said to apparently himself, his voice a bit girlier.

"But every time he wants me to do 'extra good' we end up hurt!" he argued against himself.

His left hair and left changed to a blue color now.

"Huh? As if they could harm you when I am here!" he said with a confident voice that didn't look at like any of his two other voices.

"Yeah, because captain Jonathan Havoc could be of any help here." As his left hair became actual snakes and some scales appeared on his face, Yusuke mocked himself with a girlier and somehow sexier voice.

"The hell you just said!?" Yusuke's right hair and eye changed to a blue color, like it was on the left side previously.

As Hawks saw that skinny kid argue with himself while his face changed like this, to the point it got perfectly divided in half between its hair and completely different facial expressions, his concern grew as much as his confusion.

"Let's start with Phase 1!"

As Hayato exclaimed, Yusuke jolted, and his face returned to normal. The machine guns on the ground all aimed at Yusuke.

"Ready... Now!"

The guns opened fire at Yusuke all at once. The sound of the bullets echoed in the room as they flew at Yusuke. He placed his hands in front of the bullets instinctively, not even looking at them. Luckily, just like his instincts made him try to defend himself with his arms, Yusuke's powers kicked in and all the bullets immediately stopped before touching his skin, levitating in front of the scared boy. As the gunfire stopped, he slowly opened his eyes and saw the projectiles all floating in front of him, which immediately broke his focus and made them all fall to the ground.

"Man, you really need to improve." a boy with blue hair stated.

This boy had not only somehow appeared behind Yusuke, but he was also floating in the air and looking almost like a spirit. His voice was also equal to Yusuke's when his hair was blue. Another 'spirit' showed up behind Yusuke, this one of a girl with green skin and scale, fangs and snakes for hair.

"As much as it pains me to admit it, he is right. Stop being so afraid of everything. We are invincible! Except for Yuki, he sucks." the snake girl said, also in the same voice Yusuke had when he 'became her'.

"Well, fuck you too Med." the blue boy answered the now-called Med.

"Don't slack off! Let's start phase 2!"

With Hayato's scream, the robots turned on and ran in Yusuke's direction, making loud metal sounds as they stepped on the ground with a lot of strength. The robot's arms then changed. Some got blades, others got tasers, and others just got bigger fists with spikes. Yusuke changed again, this time to the same girl with ponytails from before. Even his body changed to the body of a slightly muscular girl and she smirked, branding her sharp teeth. As she clenched her fist, her left hand glowed in a strong orange aura.

"My turn!" she exclaimed, with a voice that clearly wasn't Yusuke's.

The tough-looking girl then punched the air and her glowing fist exploded with a giant burst of lava towards the robots. In a quick attack, all the robots got destroyed and burst into flames. The amount of lava the girl blasted from her hand was surreal, even destroying the machine guns that were there and raising a thick smoke with all the things being burned by the attack.

More robots showed up. This time they had guns, and they were airborne with jetpacks. To avoid an unpleasant situation like last time, they were also spread out instead of being in a group. As they fired bullets in the girl's direction, she just scoffed and her body changed again. This time she turned into a boy with hair made of wires and whose eyes looked like screws.

"&&#******!****!" the boy made weird sounds from his mouth, almost resembling some weird static despite also looking like metal pieces clashing with each other.

The boy made pretty stiff movements with his body, looking like a robot that needed some oil. However, just as he moved, everything that was made of metal in the room also moved in the air at high speeds. The robots, the bullets, some pieces of the room, all of them flew away. Then the boy raised his hands in the air, and everything that was floating broke apart immediately, then falling to the ground.

Hayato saw of this with a serious glare, while Hawks simply looked confused and almost perplexed.

"Still not good enough." the scientist thought.

"Phase 3 now!"

The ceiling opened up, revealing even more guns suspended there, but they looked way more advanced than the other machine guns that tried to kill Yusuke before. Then futuristic weapons shone in a strong red light and made an ear-piercing sound. The wired-haired boy looked at the weapons and tilted his head in confusion. They then blasted scarlet lasers in the boy's direction, the light almost blinding Hawks and Hayato as the sound of explosions and the smell of ashes filled the control room. When the laser attacks stopped, Hawks grabbed Hayato by the neck and looked at him dead in the eyes with anger.

"Hayato, what the hell are you doing!?" the pro hero asked, slamming the old scientist on a wall "Are you trying to murder that kid!?"

"Yes. I am trying to kill him." the scientist said, much to Hawks' shock "It is the only way to truly test him and make him improve. But don't worry, I couldn't kill even if I wanted to. Observe." he then pointed at the training room, or what remained of it.

As the smoke of the room slowly dissipated, a figure became visible in the middle of the blast. It was a small boy with milk-white skin, milk-white hair, and entirely black eyes and teeth. He was currently giggling to himself.

"Yurei lived." he said while pointing to himself.

"Wonderful, because we are still not done."

More laser appeared, this time from the walls. 'Yurei' just giggled again. His laugh was kind of spooky. As the laser guns continued to blast at him, Yurei simply stood still as the lasers somehow passed right through him, now fully dodging the lasers.

"Lasers can't hurt Yurei, he is like a ghost." Yurei stated, still branding his weird smile.

The guns then changed their blasts out of nowhere. Instead of blasting red lasers, they blasted blue lasers, which now somehow hurt Yurei as it burned his shoulder.

"Gah!" the weird boy cried, before passing through the ground to protect itself from the lasers.

"Bet Yurei wasn't expecting this! It was pretty hard to make a thing that could hurt him, but we did! Now he will have to adapt!"

"Okay, that is, it! What the hell is happening!? How is this kid doing this!? Is he some kind of non-monster-looking Nomu!? What is happening!?" Hawks answered again, almost threatening the scientist with his feathers.

"Easy there, Number 2. The boy is not an experiment like those, Nomus, but he is also barely a human."

"What?"

"How can I explain it, he is... something more."

As the explanation went on, Yurei emerged from the ground and turned into a tall girl whose hair looked like it was made of glass. As the lasers tried to burn the girl into a crisp, she turned her whole body into diamond, making the lasers redirect in many directions and destroying the guns in the process.

"Just a month after he was born, the boy already showed signs he was special. He couldn't even form sentences yet he was already making things float with his mind, which was already impressive, but then when he was six he went into a museum, and suddenly everything there gained life. Paintings got out of their frames, statues screamed, and fossils walked again as pure bones. Then over the years more and more strange phenomenons happened around him..."

As Hayato continued to talk, Yusuke's body changed again, this time becoming a sort of purple gas with two eyes and a smile. As he passed through the robots and laser guns, they dissolved quickly.

"...He shape-shifted into different persons randomly, he talked with himself like he was arguing with many people, he knew about things he could never discover by its own, he saw random hallucinations that could vary between a swarm of red butterflies flying around to a giant monster destroying the living room of his house..."

The gas monster became a boy with tree roots for hair. He slammed his hand in the ground and made the ground in the room shake violently, with boulders flying everywhere as he did it.

"...He teleported to different places of his house out of nowhere, he sometimes sneezed fire, and he many other weird and inexplicable things..."

Yusuke now became a giant reptile, and he destroyed everything that remained there with its enormous claws and tail. He also expelled spikes from his arm and back.

"...all while becoming completely different beings, look and personality-wise." Hayato finished explaining to Hawks as the hero finally released him and stared at Yusuke with a shocked expression.

During Hayato's explanation, Hawks never stopped looking at Yusuke training that almost looked like glorified torture. Sure it was amateurish of him to not stare directly at the person he was interrogating, but he simply couldn't stop looking at the boy doing things we couldn't comprehend, he clearly had much more than just a simple telekinetic power but he just didn't know that was possible, especially to such an insane degree. It wasn't like Endeavor's son, who had both fire and ice powers. This was something else, something terrifying and dangerous.

"But... how?" the hero mumbled as the giant lizard reverted to Yusuke, who looked exhausted.

"Final phase now! Be ready!" Hayato shouted in the microphone, as Hawks was distracted.

Yusuke flinched, clenching his hands on his arms. He wanted to complain, but just as he prepared to scream...

"No." he spoke.

Yusuke turned his head slowly, and he saw a black fog behind him, shaped like a boy around his age. The only other discerning feature about it was its shining purple eyes with no pupils.

"You can destroy that thing easily, so suck it up and do it." His deep voice echoed in the poor boy's mind, as his surroundings shook way more violently than when the boy with root hair used his power.

Yusuke wanted to scream, he wanted to run; he wanted to leave that place right now, but he simply couldn't stop looking at the man in the fog.

"Yusuke. Yusuke! YUSUKE!" the girl with pigtails shouted, finally taking Yusuke's attention from the fog man.

As the boy looked at the girl, his fear about the fog man vanished instantly.

"Huh? What?"

"You were spacing out!"

"No, I wasn't." Yusuke answered, confused.

"Yes, you were! I have been calling you all this time, and you were just staring at that wall!" the girl shouted, pulling Yusuke's ear.

The hero and the scientist in the control room all saw Yusuke's ear being pulled by something invisible while he talked to himself.

"Ow! Okay, I am sorry!" Yusuke whined, making the girl release his ear "Gee, Hannah you are mean."

"Hannah?" Hawks asked.

"It's the girl's name. The diamond girl is called Yumi, the boy with root hair is Tsuchi, the smoke being is Caesar, the reptile creature and the boy with wire hair can't communicate so we called then Natto and Caiman, respectively."

"Wait, this doesn't answer my question! How are they-"

"They are all the same. Yet they are still their own beings."

Hawks now stopped and just contemplated what the man said.

"Please elaborate."

The walls (or what remained of them) of the training room opened, revealing a huge robot that was behind it. It reached the ceiling of the room and had a pretty bulky structure. They made him with a material that Yusuke knew from previous encounters with it that wasn't metal, and he had a plethora of weapons at his disposal to make him worthy of the title of "Final Phase".

"In the beginning, we were as confused as you now." Hayato explained, with an unsettling grin on his face "But after a long time of study and observation we concluded. Hawks, have you ever heard of D.I.D?"

"What?"

"Dissociative Identity Disorder. It is a mental disease that makes you have multiple personalities in your head, sometimes they can even 'possess' you, and the person suddenly acts like someone else. This is what happened to him. However..."

As the robot attacked Yusuke, he turned into Caesar and flew around in a gaseous form around the robot. He blew a red gas on the robot from his mouth, making the painting on it dissolve, but it left the armor almost intact outside of the paint loss. He answered by blasting lightning from one of his fingers, hurting Caesar and making him fall to the ground.

"...His powers somehow affected his condition, making his personalities... stronger and with more free will than an average alternate personality. While also making him have way more personalities than you would think was possible..."

Caesar then became Tsuchi, and he used his powers to open an enormous hole in the ground, trapping the robot inside of it and trying to trap him there. With a couple of laser blasts and jets on his boots, the robot escaped the hole easily.

"...But the funny thing is that, one day those new personas got so unique, with that much free will, that Yusuke mind acknowledged them as completely different beings that just lived on his body, and somehow that made his Quirk change in ways no one could imagine. It made their new personas gain their own unique Quirks, completely unrelated to Yusuke's. It was a miracle..."

Hannah was now in control, and she blasted a huge chunk of lave in the robot direction, effectively destroying one of his legs, but the robot held himself by grabbing a wall and counterattacked with a sound wave that made Hannah scream in agony.

"...and the powers and personas just kept rising! We talked to them and they simply never stopped showing up! This boy Quirks and personalities may as well be infinite!"

"That is impossible!"

"No, is not, and you are seeing it! Look at it!" Hayato exclaimed, his grin becoming a sick, open-wide smile.

Yusuke now took control, and he used his telekinesis to crush the robot, who was still blasting him with sound waves. Yusuke felt pain throughout his whole body, but he didn't stop using his powers. After a while, the only noises left in the training room were those of the robot being compressed into a ball of scrap and Yusuke screaming of pain and agony.

"This is the next step of Quirks! A human with infinite potential to gain new powers! Sure that All for One guy had many Quirks, sure his Nomus were scary, but this!? This is just a whole new thing! An amazing new thing!" Hayato now held Hawks by the shoulders and looked at him with concerning excitement "This is why we are training him so relentlessly despite him being a kid, this is why the Commission has such high hopes for him! He is the perfect individual being held back only by a stupid mental illness that we will surely overcome! And then he will become a hero stronger than All-Might could ever be!"

The robot was destroyed and compressed to a ball so small no one could even believe how that was possible, but Yusuke still screamed. As his screams got louder and louder, the room he was in collapsed. The walls cracked, the flood became rubble, and lights on the ceiling exploded. The boy kept screaming until his head looked like it was going to divide in two, then a scaly head that looked like a dragon appeared and breathed fire out of its mouth.

"Just think about the possibilities, Number 2! This could mean the end of Villains! Forever! Who would oppose such a being!? We tried everything! Guns, toxins, electricity, acid, even bombs! No matter the scenario, somehow he always was a power to keep himself alive!"

"You did what!?" Hawks questioned, until being interrupted by a tremendous noise coming from the control room.

As Yusuke continued to shout, the room continued to change. Trees grew and burn at a quick pace. The scientist and workers that were somewhere else in the facility were all affected in painful ways. From being turned in goo, suddenly reduced to ashes, transformed into deformed animals, to even being reverted back to infants. Everything around the area Yusuke resided in was simply chaos, except for the intact control room, despite everything that was happening around it. The boy's body changed, even more, he had a lizard and a scorpion tail growing on his butt, a pair of wings made of asking and feathers growing on his back, his hair was changing all the time and his eyes were pretty much flashing with colors.

"His personalities even vary in age. Some are old and some are young. This means we can stay alive as long as he stays with a young persona! HE MAY EVEN BE WITH US FOREVER!"

"Let me go!"

"Let's kill those other two!"

"#¨#&¨#!*&********!"

"Lord save us!"

"Guys, shut up Yusuke needs to concentrate!"

"Fuck that guy! I should be in charge!"

"Burn! Burn! Burn!"

"I want my mommy!"

"Huuuuuuuuuuungry!"

"Somebody stop all of this, please!"

"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!" as the screams in his mind got worse, Yusuke pressed his head as he tried to somehow hold the pain.

"THIS IS THE END OF THE VILLAINS! AND A BRAND NEW ERA FOR MANKIND! AN ERA OF ETERNAL PEACE! THE ERA WHERE EVERYONE WILL BE UNDER THE PROTECTION OF THE COMMISSION ALL-MIGHTY LEGION!"

"STOP THIS RIGHT NOW! DO SOMETHING ABOUT IT!" Hawks threatened the director, now using his feathers against the man.

Hayato chuckled.

"As you wish." he then pressed a button on a controller he had in his pocket.

The necklace on Yusuke's neck made a beeping sound, and he suddenly stopped screaming. He falls to the ground and his body slowly returned to normal as he now slept on the remains of the testing room.

"Tranquilizers." Hayato admitted "Very useful in this kind of situation." he now looked at a horrified Hawks "So, did you like it?"

"This is... inhumane." Hawks mumbled.

"I know, it's somewhere between monstrous and godlike in my opinion."

"I wasn't talking about him." Hawks gritted his teeth and clenched his fists so hard they almost bled, "I was talking about what you are doing with him."

"Oh, I see. It is a shame you can't see the beauty of what we are doing." Hayato said, with disappointment, "But your opinion is irrelevant. So now that you saw the progress of the project, why don't you just leave if what we do here is so disgusting to you?"

Hawks wanted to punch this man, he wanted to stab him in the face with his feathers and take this child as far away as he could from this... Torture room. But he couldn't. If he did, god knows what the commission would do with him, or the kid if they caught him again. His hands were tied, and he hated it with all his strengths.

But he wouldn't quit now. He was a hero; he allowed much awful stuff to pass because of his secret missions, but THAT? That was too much. He would not let something like this go. He would get this kid out of this hellhole, but not now. It was painful, but he needed to wait.

"Yeah, guess I will." the pro-hero then turned his back and left the place.

"It was a pleasure knowing you, Number 2, but don't get too comfortable with this position. Once he is ready, you will bounce back into being the Number 3!" Hayato said with a chuckle, making Hawks even more furious.

"Oh, I think he is ready. Ready to abandon this place! And I know how he will." the winged hero thought while he left the hidden lab without even looking back.


And that wraps today's chapter!

This is my first Boku no Hero fanfic, and it is about something I wanted to do for a relatively long time. I always loved comics and there was one particular Marvel character I liked that got little attention in my eyes, and that was Legion. So I imagined one day, what would be like if someone like him existed in the BNHA world? And decided to actually write it! This is not a crossover with Marvel comics since:

1 - I am only using one character from them and I am not following any specific story from the comics.

2 - Almost no one knows about him so I might as well just place it here to get people to actually read my story.

3 - Despite having a live-action series (Which is dope, watch it is on Netflix) I opted to use pretty much nothing from the show to make this more original. There is only one element I borrowed from the show but is not enough to justify a crossover.

4 - Even though there will be some references about Marvel characters in some of Yusuke's personas, there will also be references to many anime characters too. And they are just references, nothing more and nothing less. Two of them even showed up in this chapter.

This story will follow the canon for a while but will diverge more later, I think I made it pretty clear that this is after the All-Might and All for One battle, and the next arcs will be slightly changed to suit the addition of Yusuke, but major changes will come later. Updates will vary depending on the length of a chapter and on the fact that I am writing another fanfic too, but I will still keep up with this story. Please leave your reviews to show your support and give your criticism, and I will see you all in the next chapter!
