Shigaraki Tomura: Origin.

Shigaraki Tomura looked around him frantically, his face showing utter confusion.

Everything was black.

Wasn't he somewhere before being here? He didn't understand how he suddenly got here... Who brought him h—

"You..." Shigaraki's eyes narrowed down in hatred as a figure approached.

Izuku with no injuries, wearing a common attire approached him with controlled strides, his eyes promising retribution.

Shigaraki took a few steps back as the figure approached closer and closer, his facade of rage diminishing and being replaced with worry. "If you don't release me... Master will kill you!!" he barked out, lashing out and waving his hand before him.

"... You hurt my mom." Izuku's eyes began to glow green in the dark. "And now... Taste hell."

Shigaraki gasped, his breath shallow as he found himself standing in the middle of an abandoned city. The ruins stretched for miles, and the smell of death clung to the air like a curse. He turned, and before he could react, a black, barbed chain shot from the ground, wrapping around his throat. His eyes widened as he struggled, only to feel another chain tighten around his limbs, dragging him to the ground.

"G-gckuaaah!!" he shouted out, barbed wires impaled his throat and downed him in his own blood as he sank deep.

"Experience an unknown present."

The words echoed through his skull as the chains pulled him apart—first his arms, then his legs. Shigaraki screamed as his body was split into pieces, the agony blinding. Then—

Darkness.

He was whole again. His body was intact, but the pain of death still lingered.

Shigaraki Tomura convulsed powerfully, feeling the fantom pain of it all as he puked everywhere, eyes going crazy from the sheer stress.

Then it happened again.

A horde of shadowy figures rushed him, their claws raking across his flesh. He fought back, but they overwhelmed him, tearing at his limbs, his face, his eyes. They gnawed on his bones, feasting on his pain.

"Experience an unknown present."

Again.

A new scene. This time, he was buried alive. He clawed at the dirt, gasping for air as the weight of the earth crushed his ribs. His screams were muffled by the suffocating soil.

"Experience an unknown present."

Again.

He was drowning. His lungs burned as he sank into an abyss of water, deeper and deeper, unable to reach the surface. His vision blurred, and his chest ached with an unbearable tightness.

"Experience an unknown present."

Again.

Fire consumed him. His skin bubbled, his flesh melted away, his bones turned to ash. The flames roared around him, an inferno of suffering that stripped him down to his very soul.

"OH GOD PLEASE GOD FORGIVE ME GO—"

Shigaraki's mind began cracking apart, his beliefs as an atheist crumbling as he began to beg for salvation.

However...

This was hell.

"Experience an unknown present."

Again.

Over and over. Hundreds, thousands of deaths. Each more brutal than the last. Each one forcing his mind to shatter, piece by piece.

For many months, Shigaraki Tomura died thousands of times, experiencing countless ways of torture.

Yet he still resisted, fueled by sheer hatred that preserved his sanity.

This was all within Izuku's plan.

Izuku watched as Shigaraki twitched, his teeth clenched, his body drenched in sweat. He was still holding on. Still trying to defy reality.

Plant the hatred and fuel it to the maximum limit.

"You're strong, I'll give you that," Izuku murmured, stepping forward. "But even the strongest minds break. Let me show you the truth."

And redirect it.

The Genjutsu shifted. This time, Shigaraki stood in his childhood home. He saw himself as a child, his hands trembling as his Quirk activated for the first time. He remembered the terror, the horror of watching his family crumble to dust.

But then—

A new image. One he had never seen before.

A man in the shadows, watching from afar. The figure stepped forward, and the light revealed the sinister smile of an old man with white hair.

All For One.

Shigaraki's eyes widened. "Sensei...?"

Izuku's voice whispered in his ear, a manipulating kindness in his tone. "You think that was an accident? That your Quirk just awakened in a moment of despair? No, Shigaraki. That moment was carefully crafted."

Shigaraki jumped back, rolling few meters away from him as he whined in distress and fear.

Izuku walked forward, toward the figure of AFO.

"You never had a Quirk to begim with," he lied with ease." You were born Quirkless. A perfect vessel for All for One. Your existence was simply meant to compliment his."

"... No.... No no no no you're LYING! SENSEI WOULD NEVER DO THAT! HE SAVED ME!!!"

The scene of his family's demise played out again, but this time, Shigaraki saw the "truth". He saw the subtle glow of an unseen force around his body. He saw the slight tremor in the air, the unnatural shift as his Quirk exploded with power far beyond what it should have been.

In the distance, he heard the malicious chuckling of AFO as his family crumbled to dust and blew away with the wind, leaving his young self with nothing.

"A Quirk booster," Izuku continued, walking through the chaos. "All For One made sure you lost everything. He made sure you had nowhere to go. He made sure you would crawl to him, broken and desperate."

"L—l-lies!!"

Izuku leaned in close, his voice venomous. "You weren't chosen because you were special. You were chosen because you were easy to manipulate. Just another tool. Just another pawn in his game."

Shigaraki forward, his fist passing through Izuku like a phantom.

"You weren't saved by the devil. It is the devil himself that destroyed you."

The scene shifted to a figure that Shigaraki barely recognized.

Dabi. Someone he recruited today, a few hours ago.

"Ask him about it. He knows it all, he was a potential vessel but he managed to get away from it all, hell bent on his daddy issues."

"You... How do you know him... How do you know all of this!?"

Izuku didn't reply, walking into the darkness.

"Experience an unknown future."

Shigaraki's eyes twisted in horror. "NO!"

Another shift.

This time, Shigaraki saw a future. A future where he continued to serve All For One. He saw himself as nothing more than a mindless vessel, his body consumed by AFO, his identity erased. He was a husk, a weapon, a puppet dancing on invisible strings in the hands of his master.

"Experience an unknown future."

Another future. A world where he fought against All For One. A world where he walked a different path. A world where he—

Wasn't alone.

Besides him were the people that he recruited today, fighting in a war of his master's creation.

"... This...?" Shigaraki looked lost as the figures passed through him and fought to protect his illusion.

"A world where you made a family that loved you. You were successful in creating the best possible way to retaliate against AFO."

"...." Shigaraki's eyes began to shine a bit, liking what he was seeing.

"... However." The scene fast-forwarded a few months, Shigaraki Tomura became a hulking monster of grotesque hands with white hair, his body turning inhumane as his power skyrocketed, destroying cities with ease.

!!!

"Don't be overjoyed, watch."

The scene kept playing until Shigaraki's friends started dying one by one, slowly but surely they all died a horrific death and he was the only one standing alone.

"..."

Then... It was his turn. Shigaraki Tomura decayed like the world he envisioned in his deepest dreams, consumed by hatred with nothing left to lose.

Shigaraki fell to the ground, eyes turning soulless.

"... I... Can't win...?... Ever?..."

"No. As long as All for One controlled you, you cant."

"..."

"Now, let's watch why All for One is hell bent on destroying you," Izuku waved his hand, destroying the illusion and turning the world black.

"Experience an unknown present."

He began mind washing him, showing him countless scenarios where he was betrayed by AFO over and over and over again.

The pain was unbearable. Every time Shigaraki tried to close his eyes, the memories of his tortured existence replayed like a twisted film, his own body reacting involuntarily to the suffering. It felt like an eternity—every second stretched and twisted, his mind whirling as he tried to push the reality of the situation away.

"Stop... please, just stop!" he begged, his voice trembling, rough from the endless screams that had torn at his throat. "It's not true! None of this is real!"

But Izuku's voice, cold and unwavering, cut through the chaos.

"Experience an unknown past."

The world around him warped again. His surroundings shifted into a bleak, empty room, the air thick with the smell of dust and old sorrow. A figure stood in the corner, silhouetted by the dim glow of a dying light—a woman. She looked weary, worn by time, but there was a softness in her eyes, a kindness that seemed out of place in this nightmare.

"Meet your grandmother, Nana Shimura. She was a hero that opposed All for One's tyranny," Izuku spoke through the dark, sitting on a chair near a corner lit by a candle.

Shigaraki's mind reeled as he absorbed everything in shock. "Hero... Grandma? My family had heroes? But... My father hated heroes...."

The scene before him began to shift, unraveling like a dark tapestry. Nana Shimura sat at a small table, her head buried in her hands, as though trying to stave off the weight of something unbearable. Her shoulders trembled with quiet sobs, her breath shaky. She was alone, lost in her grief.

And then Shigaraki saw the truth—the truth that tore him apart.

Nana Shimura, with tears in her eyes, whispered to herself in the dark. "I... I just wanted to protect them. I want to see my family again..."

Shigaraki's heart hammered in his chest. The words cut through him like a blade. She wanted to see her family again. For the first time, he saw her not as a distant figure from the past, but as a human being, a woman who had lost everything.

Her family? His thoughts shattered as he tried to wrap his mind around it. Her family... she was just like him, wishing for a family. A real family.

"No... this isn't—"

But before he could finish his sentence, the scene twisted once more. His body jerked as a sickening sound filled the air—a low, guttural laugh. All For One appeared, his form looming over Nana, his face twisted in a cruel grin.

"ALL FOR ONE...!!!" Shigaraki barked with hatred, passing through the figure and trying to decay it to no avail.

Izuku smiled in the darkness.

'... Good but it can be better..'

Izuku snapped his fingers, letting the mind washing scene play out.

"Everything you love will be destroyed, Nana. Everything," he promised, his voice dripping with malice. "You thought you could hide, that you could save them all. You thought you could stop me. But now, I'll take everything from you, one by one."

Shigaraki's heart dropped into his stomach. His breaths came in ragged gasps as he fought to tear his gaze away from the scene, but his body refused to move. The weight of the truth pressed against his chest like a mountain.

"Watch."

"No! Please!" he begged, the words a frantic plea. "Tell me it's a lie! It's not true! This isn't—"

But his protests fell on deaf ears. The scene before him was unwavering, the tragedy unfolding with ruthless certainty. All For One's shadow loomed over Nana as she slowly lifted her head, her face pale and haunted by the truth.

"You could have had a life, Nana," All For One mocked. "But now, you're just another tool, another failed hero. Another statistic."

The figure of Nana Shimura trembled, her body stiff with fear, but there was no escape. Shigaraki could feel the weight of her loss, the helplessness that suffocated her in those final moments. She reached out a shaking hand, but there was no one to hold it. No one left to save her.

Shigaraki reached out to no avail.

And then All For One moved, swift and merciless, pulling a blade from the depths of his cloak. He drove it into her chest, the sound of metal meeting flesh echoing like a death knell.

"NOOOOOOO!!!!"

Nana's body fell limp, her breath shuddering with the final gasp of a life stolen.

"Goodbye, Nana. May your death be a lesson to the rest of them," All For One whispered as he stepped back, leaving her lifeless form behind.

He snapped his fingers, calling for multiple mutated dogs.

"No... no, no, no, no, no, NO! STOP THIS!!!"

The mutated dogs proceeded to devour her, tearing her broken body to shreds as they fought for pieces of her flesh.

Shigaraki fell down in despair, losing all his spirit as he began to overflow with tears.

His legs buckled beneath him, and he crumpled to the ground in defeat. The truth had been too much. The very foundation of everything he had believed in, everything he had fought for, had been built on lies.

"No..." His voice was weak, barely a whisper. "No... No..."

"He..." Shigaraki leaned forward on his hands, staring at the red floor. "He used me..?"

The realization sunk deeper than any wound ever could. He was never meant to be a successor. He was never saved. He had been nothing more than a pawn, a weapon to carry out All For One's twisted revenge against Nana Shimura.

"Experience an unknown past."

This time, the Genjutsu didn't restart with death. Instead, Shigaraki found himself standing in an unfamiliar space—cold, metallic, sterile. A laboratory. His breath hitched, eyes darting wildly as he tried to grasp what was happening.

Then he heard it.

The voice.

AFO.

His eyes darted towards three figures standing near him. Izuku stood near AFO and a man he couldn't recognize much of.

Izuku walked around the laboratory, calmly sitting on a large pipe.

Shigaraki's gaze locked onto Izuku, a silent plea of mercy in his eyes.

Izuku waved his hand, continuing the illusion.

"…The boy was useless at first," the voice sneered, arrogant, self-assured. "Pathetic, really. But I saw potential in the filth."

Shigaraki's body locked up. He turned toward the source. And there, standing before a massive operating table, was All For One himself, speaking to Dr. Ujiko, his most trusted scientist.

The old doctor nodded, scribbling notes on a clipboard. "Boosting his Quirk was a risk. Had he been any weaker, his body would have disintegrated. But your judgment was correct, my lord. The results speak for themselves."

AFO chuckled. "Of course. I needed him to be a monster, not a child. That accident with his family? A little nudge in the right direction. The moment I enhanced his Decay, they were doomed. A tragedy, really."

Shigaraki's breath caught in his throat. "No…"

"His hatred needed fuel," AFO continued, as if discussing the weather. "If he had been allowed to heal, to grow as a normal boy, he might've become useless to me. But with his entire world turned to dust in his own hands? I knew he would be desperate. Begging for guidance, for forgiveness. And I was there, waiting, ready to offer a hand."

Dr. Ujiko nodded approvingly. "You molded him well. He never even questioned it."

AFO laughed. "Of course not. He thinks his pain is his own. But in truth? I created him. Every ounce of anger, every fragment of his broken mind—I shaped it. He has never been his own person. He was always mine."

Shigaraki collapsed to his knees, hands trembling. His breath came in ragged gasps. "No. No, no, no—"

"This wasn't real. It couldn't be real!"

But deep inside, something told him it was. And that truth hurt worse than any torture Izuku had inflicted.

Izuku's voice echoed behind him.

"Now you understand everything."

The scene shifted to a nice summer breeze, sitting in an open meadow that had multiple running streams of water and the singing of wild birds.

"..."

Shigaraki didn't respond, his eyes empty as he was absorbed into his own world.

The scene continued to play out inside his mind, his grandmother torn to shreds, him forced to kill his entire family, him being controlled as a puppet and finally... Him losing everything and dying helplessly.

He began to howl in grief, his voice reaching for the sky as his mind finally crumbled apart, becoming undone.

Izuku bent down to hug him, a soothing voice with sweet words that manipulated his perception of who is good and who is bad.

For multiple months, Izuku kept on soothing him over and over and over and over again.

Izuku promised Nana to not kill him but he didn't say anything about not brain washing him.

If he can't kill him he'll give him the Batman treatment.

With this, Izuku was somewhat satisfied.

Now... Time mold him into an ally. Someone he can use.

"Come on... Let's get back to the real world."

"No... I-I can't..."

"Don't you want revenge?"

That got Shigaraki's attention.

"I'll give you strength. I'll give you revenge, I'll give you everything you need but..."

"But...?"

"You help me so I can help you."

"..."

Shigaraki thought for multiple minutes until he finally nodded, his soul lit up with revenge.

"Good, good... Now, as soon as we exit the illusion, I want you to order Kurogiri to open a portal towards U. S. J." Izuku smiled with mirth.

"... Got it, I'll help you out with everything but you must promise me something."

"Ask away."

"I.... I want —I want a friend!" Shigaraki shouted, a small blush on his face.

"..."

"..." X2

Izuku wondered if he tortured him too much...

"Could you... Elaborate?"

"All my life... I was alone... But now, you alone understand me. You alone know everything about me. You... Care about me, don't you? Otherwise you wouldn't show me all of this..."

"..."

'Holy shit thats fucking sad af!'

Izuku coughed.

"... Sure. I'll be your friend."

"Really?! I-I— Can I get your contact information? Have you played lol before? Minecraft is hella fun at night! We— we can play smash all night long!!!"

"Please don't say it like that!!!" Izuku hung his head low, an embarrassed expression on his face.

"For now, I want you to focus, got it?"

"Mhmm." Shigaraki nodded resolutely, a new light in his gaze.

A friend.

A true friend.

Something real.

Someone who cared enough to lend a hand for his drowning soul.

Unknown to himself and Izuku, he was experiencing Stockholm Syndrome.

"Ready?"

"Do it!"

Izuku broke the illusion apart, returning them to the real world.

===

Shigaraki's body smashed through multiple furnitures, planted into a wall with Izuku on top, clutching his body with black tendrils that restricted his movement.

"What the?!" Dabi jumped up, alarmed.

"Oi, oi... " Mr. Compress took a step back from the rubble, a nervous sweat falling from his face.

"Oh? It's getting interesting!" Muscular cracked his knuckles and walked to the front to see better.

"Is he dead? He's dead, right?" Toga asked curiously, tilting her head with her finger on her lips.

"Stay back..." Magne warned, putting herself between the two sides, protecting the young girl.

"Oh he definitely died..." Twice said sadly. "We get to keep the money!" Twice said happily.

From the dust, red eyes slowly emerged out as the battered form of Izuku stood up, Shigaraki held by the throat using a black tendril.

His scarred face stared at the group with a warning gaze.

"You guys...!" Shigaraki warned, coughing out as multiple splinters stung his back.

But, compared to the pain he endured all this time, it was nothing but a flesh wound.

As of now, Shigaraki has an insane pain tolerance, surpassing that of Izuku.

Izuku swayed a bit, steadying himself and preventing his falling.

"..." ths group of villains stared at the scene, horrified at the sight.

Not for Shigaraki, no. It was for the figure holding Shigaraki.

He was scarred to a horrific sight, left hand turned into a stump, right hand with no fingers. Both legs were bleeding with injuries and scratches everywhere, only covered by horrifying burns that disfigured his face and body to a monstrous form that could scare a soldier away.

"Stay... Still!" Shigaraki rasped out, struggling on the chokehold. "Do as he asks!"

Some members of the league of villains took a step back in fear, some had a neutral expression while one in particular smiled with joy.

"Kurogiri!"

"Yes, Shigaraki Tomura."

"Op—open a portal... To U. S. J."

"But sir..."

"Do as told you useless bastard!"

"... Yes."

Kurogiri waved his hand, opening a portal.

"... Stay out of my way..." Izuku slowly let Shigaraki loose. "All of you." His voice turned dark with malice.

"That voice..." Toga raised an eyebrow in realization and shock. "Izuku Midoriya? You look roughed up... I barely recognized you."

"..."

"I like what you did to your hair though," she grinned.

"..."

All the figures stayed still except for one.

"Goto Imasuji."

"Yooh!" he grinned excitedly." You know me? It seems like my fame proceeds me~"

"Move."

"Nope. I saw the fighting in the festival, you're insanely strong, aren't you? Let's fight!!"

"Muscular! Move now, it's an order!" Shigaraki shouted, enraged.

Muscular walked forward, ignoring the order entirely.

"Hell. No. I don't care about your little group of outcasts. I don't care about your silly money... All I care about is fighting. To death! Let's fight! Okay? Okay?!" he grew excited, multiple threads of muscle tissues coating his body as he dashed forward to tackle Izuku down.

"..."

Izuku intercepted the speeding beast and gripped his muscle tissue using his black tendrils, his eyes turned full red as he headbutted him into a Genjutsu.

---

In a small damp cave, Goto Imasuji opened his eyes weakly, he stared at his surroundings in utter confusion.

"What the fu—huh?" he paused, noticing his abnormal voice and short frail body.

He sounded femenine. Too femenine.

He touched his face, eyes rising in shock as he felt it.

"I'm... In a woman's body?" he asked himself, perplexed.

He tried to activate his Quirk to smash through the walls to no avail, his Quirk was gone.

"BRAT! GET ME OUT OF HERE AND FIGHT ME LIKE A MAN!!!"

No reply, his voice echoed through the cave.

"You want to fight, right?" Izuku's voice echoed back after a while.

"YES! FIGHT ME!!"

"Very well.."

Multiple snickering creatures approached Goto, carrying all sorts of weapons.

"Behold."

The goblins formed a small circle around Goto, backing him up to a corner.

Hundreds and hundreds of them crowded his frail body, snickering and licking their lips in visible lust.

"Your awaited fight."

"Oi... Don't come closer..." Goto's expression turned fearful, feeling an odd sensation of danger he never felt before.

"Don't touch me there! Stop... BACK OFF! YOU FILTHY DISGUSTING CREATURES!!!! HANDS OFF OF ME!!!!!!!"

"Enjoy."

"AHHHHHHHHHHHH—"

Izuku snapped his fingers, leaving Goto behind him in a living hell.

---

Izuku opened his eyes again, slowly descending from the frozen figure of Muscular.

"Huh? Why did he stop? Wasn't he going to fight??" Toga asked, confused.

"He is." Izuku walked to the portal. "Just not with me."

He turned fowards Dabi. "Endeavor and his family is under my protection."

Dabi's expression turned from carefree to shocked.

"Targeting them means targeting me." his eyes turned red, casting a small illusion of fire around himself. "I don't show mercy to those who oppose me, you've been warned."

Izuku walked out of the portal, leaving behind a silent group of spectators as it closed off.

"..."

No one spoke a thing, watching as both Dabi and Muscular stood in place, frozen.

Dabi was drenched in cold sweat while Muscular stood stilll, drool falling from his mouth as his eyes was dull.

Slowly, Shigaraki stood up.

He walked towards Muscular in calm steps.

"My name is Shimura Tenko," he began reintroducing himself. "And I don't like those who don't follow orders," he placed his hands over Muscular, decaying him instantly.

Under the shocked gazes of everyone, Goto Imasugi turned to dust, not even given the chance to resist.

"Pleased to meet ya~" Tenko grinned maniacally, eyes twisting in satisfaction.

He didn't feel it anymore. The itching around his neck.

He is free at last.

And now... Revenge.
