What If All For One Was a Sith Lord and Deku Was His Jedi Rival

The dust storms on the planet of Othrys did not merely blow; they screamed.

 

They howled across the jagged obsidian canyons and vast, barren wastelands of the Outer Rim world, carrying with them particles of abrasive black sand that etched away at metal, stone, and bone alike. It was a dead world, long forgotten by the bureaucratic machine of the Galactic Republic and largely ignored by the Jedi Order. There was no kyber here, no lush ecosystems pulsing with the living Force. There was only the wind, the dark, and the ghosts of a mining colony that had collapsed a century prior.

 

Yet, through the blinding maelstrom of black sand, two figures pressed forward.

 

Jedi Knight Izuku Midoriya pulled the heavy, earthen-brown fabric of his cloak tighter around his shoulders, lowering his rebreather mask just enough to clear the dust from his visor. He moved with a practiced, deliberate grace, his boots crunching softly against the crystallized rock. Even against the howling gale, Izuku’s mind was anchored in the present. He breathed in deeply, sinking into the currents of the Force.

 

To Izuku, the Force was not a gentle stream, as it was to so many of his peers back at the U.A. Jedi Temple. For the first fourteen years of his life, Izuku had been entirely "Force-blind"—a genetic anomaly in a galaxy where baseline sensitivities were growing increasingly common. He had lived in a muted world, unable to feel the hum of life, unable to reach out and touch the unseen fabric of the universe.

 

But then came the inheritance. Then came Master Toshinori.

 

Izuku’s gloved hand brushed against the cylindrical hilt clipped to his belt. It was a heavy, slightly oversized weapon crafted from a brushed silver alloy, accented with stark matte-black grips and a prominent, emitter-shroud that looked almost like a crown. Deep within its casing lay the One For All kyber crystal. It was an ancient, storied gem, passed down through eight generations of Jedi Masters. It did not sing to Izuku like normal kyber; it thrummed with a heavy, kinetic heartbeat, radiating a warmth that seeped into his very marrow.

 

"Deku! Are you meditating while walking again, or did the sand finally clog that oversized brain of yours?"

 

The abrasive voice crackled through the commlink in Izuku’s ear, sharp enough to cut through the roar of the storm.

 

Izuku blinked, pulling his consciousness back to the physical plane. A few paces ahead of him, Katsuki Bakugo stood atop a jagged promontory of rock. His Jedi robes were radically modified—sleeveless, tailored for maximum mobility, with heavy, gauntlet-like bracers wrapped around his forearms. Where Izuku’s presence in the Force was a deep, contained ocean, Katsuki’s was a raging, localized supernova. Bakugo possessed a rare, aggressive Force affinity. He didn't just push or pull objects; he excited the kinetic energy in the air to the point of volatile combustion.

 

"I'm focusing, Kacchan," Izuku replied mildly, tapping his comms. "The ambient energy here is fractured. It's like looking through shattered glass. I'm trying to pinpoint the distress beacon."

 

Katsuki scoffed, leaping down from the rock face. He didn't use the Force to cushion his fall in the traditional sense; instead, a sharp, concussive pop of compressed air expelled from his boots, arresting his momentum just before he hit the ground. "You're overthinking it, as always. The Council sent us out to this dustball because six Force-sensitive kids vanished from the Mid Rim and the tracking fob led here. We find the scum who took them, we ignite our sabers, and we take the kids back. Simple."

 

"Nothing about abducted children is simple," Izuku murmured, his brow furrowing beneath his hood.

 

Over the past standard year, a disturbing trend had emerged. Younglings—specifically those demonstrating unique, highly specialized Force affinities—were disappearing from remote colonies. The local sector authorities were useless, bogged down by jurisdiction disputes, leaving the U.A. Jedi Council to dispatch its newly knighted members to investigate.

 

"We're getting closer," Izuku said, stopping near a sheer cliff face that seemed to bleed seamlessly into the storm. He reached out with a bare hand, pressing his palm against the cold, jagged rock. He closed his eyes.

 

Breathe in. Breathe out.

 

He didn't search for light. He searched for the absence of it. And there, deep within the mountain's bedrock, he felt it. It was a cold, cloying sensation, like plunging a hand into a bucket of stagnant, freezing water. It was an unnatural void in the Force, thick with the scent of ozone, fear, and old blood.

 

"There," Izuku said, opening his eyes. They snapped to a cluster of boulders at the base of the cliff. "There's an entrance hidden behind a localized hologram projection. And Kacchan..." Izuku’s voice dropped an octave, the warmth leaving his tone. "It’s steeped in the dark side."

 

Katsuki’s crimson eyes narrowed. A savage, entirely un-Jedi-like grin pulled at the corner of his mouth. "Good. I was worried I wouldn't get to hit anything today."

 

Without waiting for Izuku, Katsuki marched toward the boulders. He didn't bother looking for a control panel or a switch to disable the holoprojection. He simply raised his right hand, splaying his fingers. The Force rushed into his palm, compressing the oxygen in the air until it sparked.

 

BOOM!

 

A concussive shockwave of thermal energy erupted from Bakugo’s hand, slamming into the rock face. The illusion flickered and died with a high-pitched mechanical whine, revealing a massive, durasteel blast door. The door itself was heavily warped and glowing orange at the center from Katsuki’s blast, groaning as the locking mechanisms melted.

 

Katsuki kicked the heavy door inward. It hit the floor of the dark corridor beyond with a resounding, metallic clang that echoed deep into the earth.

 

Izuku sighed, drawing his lightsaber hilt but leaving it unignited. "So much for the stealth approach."

 

"Stealth is for cowards who can't back up their presence," Katsuki growled, igniting his own blade.

 

With a vicious snap-hiss, a blade of pure, unstable plasma erupted from Katsuki's hilt. The color was a volatile, furious crimson-orange, crackling with errant sparks of energy that hissed against the damp air of the corridor. It perfectly matched his tempestuous spirit.

 

Izuku stepped into the gloom beside him, his thumb hovering over his own ignition switch. The moment they crossed the threshold, the howling of the wind outside was instantly muted, replaced by the low, mechanical thrum of heavy machinery and the dripping of condensation.

 

The corridor was constructed of ancient, rusted metal, illuminated only by flickering, sickly red glow-panels set into the floor. As they walked deeper into the mountain, the oppressive weight of the dark side grew heavier. It felt as though gravity itself was increasing. Izuku’s chest tightened. He relied on the fundamental Jedi breathing techniques Master Toshinori had drilled into him to keep the suffocating despair at bay.

 

"You feel that?" Katsuki muttered, his usual bravado dialed back just a fraction. He held his orange blade higher, casting stark, dancing shadows on the walls.

 

"Yes," Izuku whispered. "It feels... old. Very old. Like a grave."

 

The corridor opened up into a cavernous, subterranean chamber. As the two Jedi Knights stepped onto the elevated gantry overlooking the room, Izuku’s breath caught in his throat.

 

It was a laboratory. But not one built for healing or standard scientific inquiry. It was an abattoir of flesh and the Force.

 

Below them, arranged in neat, horrifying rows, were dozens of massive cylindrical bacta tanks. But the fluid inside wasn't the healing, translucent blue of standard medical kolto. It was a viscous, murky purple, bubbling lazily. Thick cables and respiratory tubes snaked from the ceiling, plunging into the dark liquid. Surgical droids, their chassis modified with wicked-looking saws, bone-spreaders, and hypodermic needles the size of a man’s forearm, hovered around the tanks on silent repulsorlifts.

 

And at the center of the room, carved directly into the obsidian floor, was a massive, glowing Sith rune.

 

"By the stars..." Izuku breathed, gripping the railing.

 

"Cultists," Katsuki spat, though his eyes were wide, scanning the horrifying machinery. "I knew the Sith Eternal cults were still festering in the Outer Rim, but this... this looks industrial."

 

"The missing children," Izuku said, panic spiking in his chest. He leaped over the railing, using a burst of the Force to slow his descent, landing silently on the laboratory floor. Katsuki followed, landing with a heavy, deliberate thud.

 

Izuku dashed to the nearest control console. His hands flew across the rusted, blood-stained keys. He sliced into the mainframe, his eyes darting across the red-tinted Aurebesh text scrolling down the primary monitor.

 

"Subjects..." Izuku read aloud, his voice trembling. "They call them subjects. They're cataloging Force affinities. Splicing them." He looked up, his green eyes wide with a terror he rarely allowed himself to feel. "Kacchan, they aren't just taking children to train as Inquisitors. They're extracting their connection to the Force. They're... they're grafting different Force signatures together into singular hosts."

 

Katsuki stepped up beside him, peering at the console. "That’s impossible. You can't just transplant a person's midichlorian count or their Force affinity. The host body would reject it. It would tear their mind apart. It would turn them into a—"

 

A deafening CRACK echoed through the chamber.

 

Both Jedi spun around.

 

At the far end of the laboratory, one of the massive bacta tanks was fracturing. Spiderweb cracks raced up the thick transpari-steel glass. The murky purple fluid began to leak, hissing as it hit the floor grates.

 

THUMP.

 

Something inside was hitting the glass.

 

THUMP.

 

"Get back," Katsuki commanded, stepping in front of Izuku, raising his crackling orange blade in a high guard.

 

CRASH!

 

The tank shattered. A tidal wave of foul-smelling fluid washed over the floor, carrying with it twisted shards of glass and severed respiratory tubes. From the wreckage, a massive figure rose to its feet, shaking off the viscous liquid.

 

Izuku ignited his lightsaber. A brilliant, emerald-green blade shot from his hilt with a sound like tearing thunder. The hum of his kyber crystal was deep, resonant, and immensely powerful, casting a brilliant green light across the horrific visage of the creature before them.

 

It was vaguely humanoid, but twisted beyond all recognition. It stood over seven feet tall, its skin a bruised, unnatural black, slick with chemicals. Bulging, unnatural muscles corded its arms and legs. But the most horrifying aspect was its head. The upper half of its skull was entirely missing, leaving a massive, pulsing, oversized brain completely exposed to the air. It had no eyes, only a wide, jagged maw filled with razor-sharp teeth.

 

"What in the name of the Force is that?" Katsuki whispered.

 

Through the Force, Izuku felt the creature. It did not feel like a living being. It felt like a chorus of screaming voices, multiple different Force signatures stitched together in a violently agonizing amalgamation. It was an abomination.

 

"It's what the records called them," Izuku said, his grip tightening on his hilt until his leather gloves creaked. "A Nomu."

 

The Nomu let out a screech that sounded like grinding metal, and lunged.

 

Its speed was staggering. It cleared the fifty feet between them in a fraction of a second. Katsuki reacted on pure instinct. He swung his orange blade in a wide, decapitating arc.

 

The lightsaber connected with the creature's thick, muscular neck. But instead of slicing through flesh and bone, the plasma blade met immense resistance. The Nomu’s skin shimmered with a dark, kinetic barrier—a Force shield, projected entirely on reflex. The creature absorbed the immense heat of the lightsaber, grabbed Katsuki’s wrist with a hand the size of a dinner plate, and hurled the Jedi across the room. Katsuki smashed into a durasteel pillar, the metal buckling under the impact.

 

"Kacchan!" Izuku cried.

 

The Nomu pivoted, its eyeless face snapping toward Izuku. It raised its hand, and the air around it rippled.

 

Force Push.

 

But this wasn't a standard, disciplined push. It was a chaotic, unfocused blast of dark side energy. The shockwave tore up the floor grates and sent heavy surgical droids flying.

 

Izuku didn't try to block it. He closed his eyes and breathed in, sinking deep into the bond of the crystal.

 

One For All.

 

For Izuku, the Force was not something he manipulated externally. His body was a fragile vessel, and the power he had inherited was an ocean. To survive, he had to channel the Force directly into his musculature, enhancing his physical attributes to superhuman levels.

 

Full Cowling: Twenty Percent.

 

Izuku opened his eyes. Brilliant, glowing green lines of energy mapped themselves across his skin beneath his robes. Arcs of emerald lightning sparked and crackled off his body, whipping the air around him. The dark side shockwave hit him, but Izuku merely braced his legs, the Force grounding him to the floor. The kinetic blast washed over him, parting around his aura like water around a stone.

 

Before the Nomu could recover, Izuku moved.

 

He left a crater in the steel floor where he had been standing. Moving faster than the eye could track, Izuku appeared directly above the massive beast. He brought his emerald blade down in a devastating, two-handed vertical strike.

 

The Nomu raised its arms in an X-block, generating another shimmering Force shield. The green plasma clashed against the dark energy barrier, showering the room in blinding white sparks. Izuku grit his teeth, the muscles in his arms screaming as he pushed more of the One For All energy into the kyber crystal. The green blade grew thicker, hotter, the kinetic resonance vibrating up Izuku’s arms.

 

The shield cracked.

 

The Nomu shrieked, suddenly opening its maw. A torrent of blistering blue fire erupted from its mouth—a localized pyrokinesis affinity, stolen from some poor soul and grafted into this monster.

 

Izuku was forced to break his lock, backflipping through the air to avoid the flames. He landed smoothly, his boots sliding backward on the slick floor.

 

"Deku! Get down!"

 

Izuku dropped into a crouch instantly.

 

From the shadows behind the Nomu, Katsuki bounded off the wall, using his Force-combustion to propel himself like a missile. He was spinning like a drill, his orange lightsaber extended.

 

"Howitzer... IMPACT!" Katsuki roared.

 

He didn't just slash the creature; he channeled an immense concentration of volatile Force energy into the tip of his blade. When the plasma met the Nomu’s back, Katsuki released the tension. A massive explosion of fire and Force energy detonated at the point of impact.

 

The blast tore through the laboratory, shattering the remaining empty bacta tanks and blowing out the overhead lights. The Nomu was thrown forward, half of its torso blown away, black blood spraying across the floor. It hit the ground, twitched violently for a moment, and then lay still. The chaotic chorus of voices in the Force went abruptly, sickeningly silent.

 

Izuku slowly stood up, the green lightning fading from his skin. He breathed heavily, deactivating his lightsaber. The emerald blade vanished with a hiss, plunging the room into darkness, save for the glow of Katsuki’s orange saber and the sparks from the ruined machinery.

 

Katsuki walked over to the corpse, his chest heaving, his face covered in soot. He kicked the creature's massive arm. "Force-resistant skin. Shockwave emission. Fire breathing," he listed, his voice tight with disguised horror. "That wasn't one creature. That was three different Force-sensitives, jammed into a blender."

 

"This is an atrocity," Izuku said, walking over to the main console. He found a data-spike in his belt and jammed it into the port, downloading every file, every sick blueprint he could find. "We have to get this to the Council. If the Sith Eternal cults have figured out how to forcibly transfer Force affinities..."

 

"Look," Katsuki interrupted, pointing his saber toward the back of the room.

 

Behind the shattered tank the Nomu had emerged from, set into an alcove in the stone wall, was a small pedestal. Resting atop it was an object that made Izuku’s stomach churn.

 

It was a pyramid, roughly the size of a fist, constructed of dark, reflective obsidian and etched with glowing, blood-red circuitry.

 

"A Sith Holocron," Izuku whispered.

 

He approached the pedestal as if it were a coiled viper. The closer he got, the more the air temperature dropped. His breath plumed in small white clouds. The dark side here was suffocating, thick like tar. But it wasn't the ambient darkness that made Izuku freeze.

 

It was his lightsaber.

 

The hilt at his waist began to vibrate. It wasn't a mechanical malfunction. The One For All crystal inside was reacting. Izuku could feel a sharp, piercing pain in the back of his mind—a psychic alarm bell ringing so loudly it made his vision blur. The crystal was terrified.

 

Do not touch it, a voice seemed to whisper in Izuku’s mind. It wasn't his own thought. It felt like an echo, a memory of a voice long dead.

 

Izuku reached out with his gloved hand. He didn't touch the Holocron physically; he used the Force to gently lift the pyramid off the pedestal.

 

The moment the Holocron left the stone, the red circuitry flared with a blinding light.

 

The laboratory around Izuku vanished. Katsuki’s voice faded into static. The cold disappeared, replaced by a sensation of falling through an endless, suffocating void. Izuku’s mind was violently ripped from his body, dragged across the galaxy through the ethereal plane of the Force.

 

He saw flashes of nightmare imagery: Entire planets burning. A fleet of triangular Star Destroyers eclipsed in shadow. A gaunt, skeletal hand reaching out to crush a shining star. And finally, a face.

 

It was barely a face at all. It was a man, ancient beyond reckoning, his skin pale and stretched tight over a skull that lacked eyes, a nose, or hair. The upper half of his face was a scarred, ruined expanse of scar tissue. The lower half was covered by an intricate, terrifying cybernetic breathing mask that hissed with a rhythmic, mechanical dread.

 

Inhale... Exhale...

 

The sound of the breathing filled the void, louder than thunder.

 

And then, the entity spoke. The voice didn't enter Izuku’s ears; it bypassed his physical senses entirely, slithering directly into the core of his mind. It was a cultured, aristocratic voice, dripping with centuries of cold, calculated malice.

 

"Ah..." the voice purred, smooth as velvet over broken glass. "I feel it. The spark of my little brother's rebellion. The crystal endures."

 

Izuku tried to pull away, tried to sever the connection, but his mind was pinned. The sheer, overwhelming power of the consciousness holding him was unlike anything he had ever felt. Even Master Toshinori, in his prime, did not possess a presence this dark, this absolute. It was a black hole, consuming all light around it.

 

"You wear a heavy burden, little Jedi," the Sith Lord mocked. "You carry the hopes of dead men. The ghosts of eight fools who thought they could defy the natural order of the galaxy."

 

"Who are you?" Izuku thought, his mental voice trembling, though he fought to keep it steady.

 

A cruel, chilling laugh echoed through the void.

 

"I am the architect of your doom, child. I am the collector of power. And I see you. I see your fears, your inadequacies. I see the boy who was born with nothing, who borrows his strength from a dying relic." The presence leaned closer, suffocating Izuku. "Tell Toshinori that his failure is complete. The age of the Jedi is over. The All For One will consume the light. And I will start... with you."

 

CRACK!

 

Izuku gasped, his eyes flying open as he stumbled backward. He hit the cold steel floor of the laboratory, gasping for air as if he had been drowning.

 

"Deku! Hey, Deku! Snap out of it!"

 

Katsuki was kneeling beside him, his hand gripping Izuku’s shoulder tight enough to bruise. For once, Katsuki didn't look angry. He looked genuinely unnerved.

 

Izuku blinked, the grim reality of the bloody laboratory coming back into focus. The Holocron was lying on the floor a few feet away, its red light dimmed to a dull, lifeless pulse. Izuku was shivering violently, sweat pouring down his pale face.

 

"What happened?" Katsuki demanded, hauling Izuku to his feet. "You picked that thing up with the Force, and you just froze. Your eyes rolled back, and the air around you got... cold. What did you see?"

 

Izuku looked down at the hilt of his lightsaber. The crystal inside was silent now, but the metal was still warm to the touch. He swallowed hard, trying to push down the rising tide of absolute terror that threatened to drown his composure.

 

"We need to get back to Coruscant," Izuku said, his voice ragged. "We need to go back to the Temple immediately. We have to warn Master Toshinori."

 

Katsuki frowned, grabbing his commlink. "Warn him about what? A cult?"

 

"No," Izuku said, staring at the dark doorway that led back to the surface. "Warn him that the monster who crippled him... the Sith Lord who killed the past Masters..." Izuku closed his eyes. "He's alive. All For One has returned."

 

 

 

The journey back to the Core Worlds took three standard days in hyperspace, but to Izuku, it felt like a millennium.

 

He sat in the cramped meditation chamber of their delta-class starfighter, the shards of the shattered Sith Holocron locked securely in a containment box. He had barely slept. Every time he closed his eyes, he heard the rhythmic, mechanical breathing. He felt the cold, skeletal presence invading his mind. He spent the hours running through moving meditation, disassembling and reassembling his lightsaber with his eyes closed, finding comfort in the mechanical precision of the kyber chamber.

 

When they finally dropped out of hyperspace, the brilliant, city-covered sphere of Coruscant—now known as Musutafu Prime in the Republic registers—filled the viewport. It was a jewel of light in the dark expanse of space, a symbol of order and peace that had stood largely unchallenged for decades.

 

They bypassed the standard traffic lanes, authorized by their Jedi clearance, and descended directly toward the U.A. Jedi Temple.

 

The Temple was a breathtaking architectural marvel, a massive ziggurat of gleaming white stone and shimmering glass turrets, perched atop one of the highest structural plateaus on the planet. Serene waterfalls cascaded down the sides of the structure into massive meditation gardens, a stark contrast to the endless durasteel cityscape surrounding it.

 

Izuku and Katsuki didn't stop to greet their fellow Knights or the young Padawans sparring in the courtyards. They walked with hurried, purposeful strides through the echoing, vaulted halls, ignoring the questioning glances from passing Jedi.

 

They took the turbolift to the highest spire: the High Council Chamber.

 

The doors slid open with a soft hiss. The chamber was circular, bathed in the golden light of the setting sun pouring through the panoramic transpari-steel windows. The floor was polished marble, reflecting the silhouettes of the two Jedi Masters waiting for them.

 

Sitting in a hover-chair near the center of the room was Grand Master Nezu. A highly unusual being, Nezu was a small, mammalian alien of indeterminate species—resembling a cross between a mouse, a bear, and a dog. Despite his diminutive stature and pristine white fur, his presence in the Force was a vast, intricate web of pure, unparalleled intellect and calm.

 

Standing by the window, looking out over the sprawling city, was the man Izuku had come to see.

 

Master Toshinori Yagi.

 

To the rest of the galaxy, he was known as All Might—the greatest Jedi Master of the modern era, the Symbol of Peace, the man who had single-handedly broken the back of the Sith resurgence twenty-five years ago. In his prime, he had been a titan, radiating a light so blinding it chased away the shadows of the Outer Rim.

 

But the man standing by the window was a ghost of that legend.

 

Toshinori was gaunt, his robes hanging loosely over a skeletal frame. His face was hollow, with sharp cheekbones and deeply sunken, shadowed eyes. A terrible, ragged cough wracked his thin body, and he held a handkerchief to his mouth. When he lowered it, Izuku saw a speck of blood on the white fabric.

 

"Izuku, Katsuki," Nezu said, his voice cheerful, though his black, beady eyes were sharp and analytical. "You have returned earlier than anticipated. I sense turbulence in the Force around you both. The mission to Othrys did not go as planned, I presume?"

 

Izuku stepped forward, bowing respectfully to Nezu, and then to Toshinori as the tall, blonde man turned around.

 

"Masters," Izuku said, his voice echoing in the quiet chamber. "We found the missing children. Or, at least, what was left of them."

 

Katsuki tossed the data-spike onto the council table. "The cultists are building monsters. They call them Nomu. They've found a way to forcibly extract Force affinities from living hosts and graft them together. The creature we fought had three distinct signatures. It took everything we had to put it down."

 

Toshinori’s hollow blue eyes widened slightly. He stepped forward, leaning heavily on a cane. "Extracting Force affinities? That... that is a dark side art that has not been seen in centuries. A corruption of the highest order."

 

"It's worse, Master," Izuku said, pulling the containment box from his belt and setting it on the table. He opened it, revealing the fragments of the Sith Holocron. "I found this at the facility. When I touched it... it triggered a localized Force vision. I... I spoke to someone."

 

Toshinori froze. The temperature in the room seemed to drop, the golden sunlight suddenly feeling very cold. The old Master stared at the red shards of the Holocron, a phantom pain flaring in his left side, beneath his robes, where a massive, spider-webbing scar covered half his respiratory system.

 

"A voice..." Toshinori rasped, his usually booming voice reduced to a fragile whisper. "Describe it, Young Midoriya."

 

Izuku looked up at his mentor, hating the fear he saw in the old man's eyes. "It was cold. Mechanical. He wore a breathing mask. And he... he recognized my lightsaber, Master. He called the crystal the 'spark of his little brother's rebellion.' He said the All For One will consume the light."

 

Silence descended upon the Council Chamber. It was total, absolute, and heavy with a suffocating dread.

 

Katsuki looked between Izuku and Toshinori, his brow furrowed in confusion and rising anger. "Will someone tell me what the hell is going on? Who is All For One?"

 

Toshinori closed his eyes. A single tear slipped down his gaunt cheek. He collapsed into a nearby chair, leaning his head on his cane. He looked incredibly, terribly old.

 

"I thought he was dead," Toshinori whispered, his voice trembling. "I struck him down. I saw him burn. I gave up my connection to the Force, shattered my own body to ensure he would never rise again."

 

Grand Master Nezu folded his paws together, his whiskers twitching. "It appears, my old friend, the dark side holds secrets of preservation that defy reason. If Darth Shigaraki lives, then the peace we have enjoyed is nothing but a fleeting illusion."

 

"Darth Shigaraki," Izuku repeated, the name tasting like ash in his mouth.

 

"He is a parasite," Toshinori said, looking up, his blue eyes blazing with a sudden, fierce intensity. "He is an ancient Sith Lord who discovered a forbidden technique. He does not merely use the dark side, Izuku. He steals the Force from others. He strips a Jedi of their affinity, absorbing it into himself, leaving them an empty, vegetative husk. He uses their power to extend his unnatural life. The Nomu you fought... they are his twisted experiments, an attempt to mass-produce his unique, horrific power."

 

Toshinori stood up, walking over to Izuku. He placed a bony, trembling hand on Izuku's shoulder.

 

"The crystal you wield, One For All... it was created by his younger brother. A Jedi who believed that power should be freely given, not taken. It is the only power in the galaxy that Darth Shigaraki cannot steal, for it can only be transferred willingly. It is his antithesis. And now that he knows you have it..."

 

"He will come for me," Izuku finished, his voice steady despite the icy terror gripping his heart.

 

"He will tear the galaxy apart to get to you," Toshinori corrected.

 

 

 

Far beyond the borders of the Republic, past the treacherous hyper-space anomalies of the Unknown Regions, lay the Sith world of Tartarus.

 

It was a planet of jagged, black basalt mountains and oceans of raging, crimson lava. The sky was permanently choked with ash and violet lightning. At the magnetic north pole of the planet stood a massive citadel, a spire of dark metal piercing the storm clouds like a poisoned dagger.

 

Deep within the bowels of the citadel, in a chamber suspended over a chasm of molten rock, Darth Shigaraki rested.

 

The Sith Lord known as All For One sat upon a massive, medical throne. Thick, black cables snaked from the ceiling, plunging into his spine, his arms, and his chest. His body was ruined, held together by dark side alchemy and cybernetic life support. The upper half of his face was a featureless expanse of scarred tissue. Below, a heavy, black mechanical rebreather covered his mouth and nose, hissing with every labored breath.

 

Inhale... Exhale...

 

The doors to the chamber slid open, grinding against stone.

 

A young man walked in. He was tall, incredibly pale, with unkempt, pale-blue hair that hung in his eyes. He wore black robes, but his appearance was unsettling. Clasped around his neck, shoulders, and arms were the preserved, mummified hands of Jedi he had slain. He scratched violently at his own neck, peeling away flakes of dry skin, his crimson eyes burning with an unhinged, chaotic hatred.

 

This was Tomura Shigaraki. Darth Decay. The apprentice.

 

Tomura knelt before the throne, bowing his head. "Master."

 

All For One did not move, but his voice echoed from the vocalizer in his mask, rich and commanding.

 

"My apprentice. The grand design moves forward into its final stage. The Republic grows fat and blind, trusting in a Symbol of Peace who is nothing but a hollow, broken shell."

 

"The fleet is ready, Master," Tomura rasped, his voice sounding like dry leaves. "The Inquisitors are hungry. Give the word, and I will reduce the Jedi Temple to dust. I will turn their precious society to ash. Everything will decay."

 

"Patience, Tomura," AFO said softly, a dark amusement threading through his mechanical voice. "Destruction is simple. A brute's tool. We are artisans. But there is a loose thread in our tapestry. A newly anointed Jedi Knight. A boy in green."

 

Tomura stopped scratching his neck, looking up. "A boy?"

 

"He carries a crystal," AFO said, and for the first time, a hint of venom entered the aristocratic voice. "A crystal that belongs to me. He is the successor to Toshinori Yagi. The new vessel for One For All."

 

Tomura’s crimson eyes widened, a sinister grin spreading across his chapped lips. "All Might’s brat. You want me to kill him?"

 

"No," AFO commanded, the sheer pressure of his dark side presence forcing Tomura's head back down to the floor. The gravity in the room intensified, the lava below bubbling violently. "You will break him. You will slaughter his friends. You will raze his Temple, destroy his faith, and leave him with nothing but despair. And then, you will bring him to me. Alive. I wish to shatter my brother's legacy with my own hands."

 

Tomura chuckled, a dry, wheezing sound. "As you command, Master."

 

"Go, my apprentice," All For One breathed, the cybernetic hiss echoing through the dark chamber. "Let the galaxy remember why they fear the dark."

 

 

 

The Room of a Thousand Fountains was usually the most tranquil sanctuary within the U.A. Jedi Temple. Located deep within the eastern wing, it was a sprawling, tiered atrium filled with bioluminescent flora brought from across the Republic, gently flowing waterfalls, and polished stone meditation pads. The air was always humid and sweet, vibrating with the gentle, harmonious hum of the living Force.

 

Today, however, the tranquility was shattered by the sharp, concussive snap-hiss of igniting lightsabers and the smell of ozone.

 

"Your guard is too high, Todoroki. You're relying too much on your affinity to keep me at bay!"

 

Tenya Iida moved like a blurred projectile. The tall, bespectacled Jedi Knight wore armor-plated robes, rigid and aerodynamic. His Force affinity was highly specialized: he channeled kinetic energy directly into his legs, allowing him to move in explosive, linear bursts of superhuman speed. He darted across the water-slicked stones, his blue lightsaber leaving a cerulean trail in the air as he thrust toward his sparring partner.

 

Shoto Todoroki didn't blink. The young Jedi, whose hair was evenly split between stark white and deep crimson, merely pivoted on his heel. He didn't raise his own lightsaber to block. Instead, he raised his right hand. The ambient moisture in the room instantly coalesced, the temperature plummeting to absolute zero in a fraction of a second. A massive, jagged wall of blue-white ice erupted from the floor, intercepting Iida’s strike.

 

Iida’s blue plasma blade bit deep into the ice, hissing violently as it melted the frozen barrier, but his momentum was completely arrested.

 

"A guard is unnecessary if the opponent cannot reach me," Shoto replied smoothly, his voice a calm, detached monotone. He stepped around the melting ice wall, his left hand rising. The air around his left side shimmered with intense heat. Shoto possessed a dual-affinity—a rarity in the Order—capable of manipulating both thermal extremes. He prepared to unleash a wave of telekinetic fire to push Iida out of the sparring ring.

 

"Guys, watch the flora! Master Kamui will have our heads if we scorch the wroshyr saplings again!"

 

Floating cross-legged ten feet in the air above them, Ochaco Uraraka watched the spar with an anxious smile. Her Force affinity was centered around gravity manipulation; she could render herself and whatever she touched entirely weightless, allowing her to float and maneuver with zero-G grace. Her pink-bladed lightsaber hung unignited at her hip.

 

Sitting on a stone bench at the edge of the water, Izuku Midoriya watched his friends. He wore a simple tunic, his emerald lightsaber resting across his knees. He smiled at Ochaco’s warning, but the smile didn't quite reach his eyes.

 

It had been four days since he and Katsuki had returned from the nightmare on Othrys. Four days since the shattered Sith Holocron had broadcasted the voice of the ancient terror into his mind. All For One.

 

The High Council had immediately placed the Temple on high alert. Planetary defense shields around Musutafu Prime were raised to maximum output, and the Jedi Sentinels were working triple shifts. But the waiting was tearing Izuku apart. He could still feel the phantom coldness of that mechanical breathing in the back of his mind. He looked down at his right hand. It was trembling slightly.

 

"Deku?"

 

Ochaco deactivated her levitation, dropping lightly to the stone floor next to him. She tilted her head, her large brown eyes full of concern. "You're projecting again. The water in the fountain next to you is vibrating."

 

Izuku blinked, looking at the pool of water. Sure enough, the surface was dancing with chaotic ripples, reacting to the latent kinetic energy leaking from his anxious mind. He took a deep breath, consciously releasing his tension into the Force. The water stilled.

 

"Sorry, Uraraka," Izuku murmured. "I just... I can't shake this feeling. It's like standing on the beach, watching the tide pull all the water out to sea. You know a tsunami is coming, but there's absolutely nothing you can do to stop it."

 

Before Ochaco could offer a word of comfort, the Force screamed.

 

It wasn't a subtle shift or a gentle warning. It was a violent, physical blow to the senses. Every Jedi in the room staggered. Iida dropped to one knee, clutching his head. Todoroki’s ice wall shattered into a thousand pieces as his concentration broke. Izuku gasped, dropping his lightsaber as a wave of pure, suffocating darkness washed over the entire planet.

 

Then came the sirens.

 

A blaring, deafening klaxon erupted throughout the Temple corridors. The gentle ambient lighting of the Room of a Thousand Fountains snapped off, instantly replaced by the harsh, rotating crimson glare of emergency battle stations.

 

“ALERT. ALERT.” A mechanical PA system boomed. “PLANETARY SHIELD BREACH DETECTED IN SECTOR ONE. HOSTILE INCURSION IMMINENT. ALL JEDI KNIGHTS TO THE COURTYARDS.”

 

"Sector One?" Iida shouted over the sirens, recovering quickly and snapping his blue lightsaber to his belt. "That's directly above the Temple! How did a fleet bypass the Republic armada?"

 

"They didn't," Shoto said, his heterochromatic eyes wide as he looked up through the massive glass domed ceiling of the atrium. "Look."

 

High above the planetary atmosphere, the sky was tearing open. But it wasn't the clean, brilliant flash of a ship exiting hyperspace. The sky looked like it was bleeding. Massive, jagged tears of dark, red-black energy ripped through the atmosphere—Sith space-fold magic, an ancient and highly unstable method of teleportation used to bypass conventional shields.

 

From the bleeding rents in the sky, dozens of massive, obsidian drop pods plummeted directly toward the Temple.

 

"They're not just attacking the city," Izuku realized, his blood running cold as he scooped up his lightsaber. The memory of the Holocron flashed in his mind. I will start with you. "They're targeting the Order. They're here for us!"

 

The first drop pod hit the Temple's eastern wing.

 

The impact was like an earthquake. The floor beneath them buckled, throwing Izuku and the others to the ground. The massive glass dome above the Room of a Thousand Fountains shattered completely, raining razor-sharp shards down upon them.

 

"Uraraka!" Izuku yelled.

 

Ochaco thrust her hands upward. She didn't push the glass away; she altered its gravity. The thousands of falling shards suddenly stopped in mid-air, floating harmlessly like deadly snowflakes. Shoto followed up immediately, unleashing a blast of freezing wind that blew the suspended glass safely into the far wall.

 

"We need to get to the main courtyard!" Iida barked, taking charge. "The younglings are in the western wing, we have to hold the line so Master Aizawa and the instructors can evacuate them to the vaults!"

 

"Go!" Izuku shouted, igniting his emerald blade. The deep, resonant hum of One For All filled his ears, steadying his racing heart. "I'm right behind you!"

 

The four young Knights sprinted out of the atrium, tearing through the winding, vaulted corridors of the Temple. Dust and debris rained from the ceiling. Outside the massive arched windows, they could see the pristine meditation gardens burning.

 

They burst through the massive front doors of the Temple and out onto the Grand Steps.

 

The scene was absolute chaos.

 

The sprawling courtyard, usually a place of quiet reflection, was a warzone. Half a dozen obsidian drop pods had cratered into the stone. The heavy ramps fell with mechanical groans, and the darkness spilled out.

 

They were not Sith troopers. They were monsters.

 

Dozens of Nomu poured from the transports. They varied in size and shape, some possessing wings, others covered in thick, bony armor plates, but all shared the same bruised skin and exposed, pulsing brains. They roared, unleashing a chaotic barrage of stolen, mismatched Force abilities—acid spit, sonic screams, and telekinetic shockwaves.

 

Jedi Knights and Masters were already engaged, brilliant flashes of green, blue, yellow, and purple plasma clashing against the monstrous horde.

 

But behind the Nomu walked the true threat.

 

They wore dark, ragged robes, their faces hidden by masks or shadows. They carried lightsabers, but their blades were the uniform, bleeding, synthetic crimson of the Sith. These were the Inquisitors—the League of Villains. Cultists who had sworn their lives to Darth Shigaraki in exchange for a fraction of his dark power.

 

"Burn it down," a lazy, cruel voice echoed across the courtyard.

 

An Inquisitor stepped forward. He was tall, his skin held together by crude staples and horrific burn scars. He wore a heavy leather trench coat. He didn't ignite a lightsaber. Instead, he raised his hands, palms facing the Temple.

 

Dabi.

 

He unleashed a torrent of corrupted Force-pyrokinesis. The flames were not standard red or orange; they were a blinding, blindingly hot cobalt blue. The wall of blue fire roared across the courtyard, instantly incinerating a squad of Temple guards and melting the ancient stone statues of past Masters.

 

"I'll take the pyromaniac," Shoto said, his voice dropping to a dangerous, icy register. He leaped from the top step, sliding down a ramp of his own ice, his right side flaring with his own standard flames to counter the blue inferno.

 

"Todoroki, wait!" Iida yelled, but a sudden, high-pitched giggle diverted his attention.

 

A female Inquisitor—blonde, wearing a twisted mockery of a school uniform—bounded across the battlefield with unnatural, Force-enhanced agility. Himiko Toga. She wielded two short, jagged crimson shoto-sabers. She blurred, using a dark side illusion technique to multiply her form, creating a dozen holographic clones that swarmed a group of fleeing Padawans.

 

"Iida, with me!" Ochaco yelled, igniting her pink lightsaber. "We have to protect the younglings!"

 

Iida nodded, his engine-legs firing as he launched himself toward the illusionist, Uraraka floating right behind him, using the Force to hurl massive chunks of debris at the Inquisitor.

 

Izuku was left at the top of the steps, his emerald blade casting a green glow over his face. He watched his friends engage, his tactical mind cataloging the battlefield. He prepared to leap down to assist Shoto, but a sudden, overwhelming spike in the dark side rooted him to the spot.

 

It was a cold so profound it felt like a physical weight settling on his chest. It tasted like ash and rot.

 

The fighting in the center of the courtyard seemed to organically part, Jedi and Nomu alike backing away instinctively.

 

From the largest of the drop pods, a single figure emerged.

 

He moved slowly, with a shuffling, almost bored gait. He wore a dark, dusty tunic and black trousers. But it was the macabre adornments that made Izuku’s stomach heave. Clasped around the man's neck, gripping his shoulders, and covering his face were severed, mummified hands.

 

Through the gaps in the hand covering his face, Izuku saw a single, blood-red eye lock onto him.

 

Darth Decay. Tomura Shigaraki.

 

"There you are," Tomura rasped. He didn't shout, but through the dark side of the Force, his voice carried directly into Izuku’s ears, dry and abrasive. "The final boss. The reset button."

 

Tomura raised his right hand. He didn't hold a lightsaber. He simply pointed a single, pale finger at a massive, ancient wroshyr tree in the center of the courtyard—a tree that had stood for a thousand years.

 

He tapped the trunk.

 

The effect was instantaneous and horrifying. The point of contact turned gray. The gray spread with terrifying speed, racing up the massive trunk, out to the branches, and into the leaves. The wood dried out, petrified, and then, with a sound like a crumbling sandcastle, the entire massive tree collapsed into a pile of fine, gray dust.

 

Decay. Dark side alchemy at its most lethal, absolute extreme.

 

Tomura lowered his hand, his red eye fixed on Izuku. "Everything connected to him crumbles. Your Temple. Your friends. Your legacy. I'm going to dust it all."

 

Izuku didn't hesitate. He didn't feel fear, only a profound, resolute clarity.

 

He closed his eyes and reached inward, grabbing hold of the massive, kinetic reservoir of the One For All crystal. He didn't just let the Force flow through him; he forced it into his musculature, overloading his nervous system with raw, crackling power.

 

Full Cowling: Thirty Percent!

 

Brilliant, jagged arcs of green lightning erupted from Izuku's body, whipping the air around him. The stone beneath his boots shattered.

 

With a boom that echoed over the din of battle, Izuku launched himself from the top of the Temple steps. He cleared the fifty-yard distance in a single, parabolic leap, descending like a green meteor. He gripped his heavy silver hilt with both hands, bringing the emerald blade down in a devastating overhead strike aimed directly at Tomura.

 

Tomura didn't flinch. At the last possible microsecond, he sidestepped. He moved with a lazy, unnatural fluidity, letting the dark side guide his body.

 

Izuku’s lightsaber slammed into the stone courtyard. The kinetic force of the blow, amplified by Full Cowling, created a localized earthquake. A massive crater erupted around them, blowing away dust and sending several nearby Nomu tumbling to the ground.

 

Izuku didn't pause to recover. He used the momentum of the strike to pivot, sweeping his leg low in a sweeping kick aimed at Tomura’s shins. But Tomura vaulted over the leg, floating momentarily in the air, and reached down with his bare left hand toward Izuku’s face.

 

Danger Sense.

 

A sudden, sharp spike of pain flared in Izuku’s head—a latent ability inherited from the fourth user of One For All, granting him hyper-precognition. Izuku violently threw his head back. Tomura’s fingers missed his face by a millimeter.

 

Izuku pushed off the ground, backflipping into the air and landing ten paces away. He kept his lightsaber in a high guard, breathing heavily. The green lightning continued to arc across his skin, but his muscles were already burning.

 

"You're fast," Tomura noted, tilting his head. He scratched at his own neck with four fingers. "Like a panicked little rabbit. But you rely entirely on physical enhancement. You treat the Force like a blunt instrument. So uncivilized."

 

With a flick of his wrist, a cylindrical hilt fell from Tomura’s sleeve into his hand. With a hateful hiss, a thin, unstable crimson blade ignited. The plasma sputtered and crackled, reflecting the chaotic instability of its master.

 

Tomura lunged.

 

He didn't use a formal lightsaber form like Makashi or Soresu. His attacks were wild, unpredictable, and devastatingly lethal. He swung the red blade in wide, jagged arcs, leaving trails of afterimages in the air.

 

Izuku met the assault head-on. Green clashed with red, showering the crater in blinding sparks. Izuku’s combat style was highly unorthodox for a Jedi. Because One For All enhanced his entire body, he didn't just rely on blade work. He parried a heavy downward strike, slid his foot forward, and drove a Force-enhanced elbow directly into Tomura’s chest.

 

Tomura was thrown back, but he used the momentum to flip through the air, landing softly on his feet. He immediately retaliated by thrusting his empty hand forward. A wave of dark telekinesis hit Izuku like a physical wall, throwing the young Jedi backward.

 

Izuku dug his heels into the stone, dragging to a halt. He raised his blade just in time to block a vicious thrust aimed at his throat.

 

The two sabers locked. The emerald and crimson plasma ground against each other, the energy field shrieking in protest. They were inches apart. Izuku could smell the rotting, chemical stench emanating from Tomura’s robes.

 

"Why are you doing this?" Izuku gritted out, his arms straining as he pushed against the lock. "The Republic has stood in peace for decades! Why slaughter innocents?"

 

"Peace?" Tomura scoffed, a horrific sound behind the mummified hand on his face. "Your peace is a lie. It's a society built on the backs of those deemed 'unworthy' by the Force. Your Jedi Council sits in their ivory towers, hoarding knowledge, while the rest of the galaxy rots. We are just accelerating the decay."

 

Tomura suddenly disengaged the saber lock, letting Izuku’s momentum carry him forward slightly.

 

It was a trap.

 

Tomura reached out with his free hand, his fingers splayed. He didn't aim for Izuku’s body. He aimed for the weapon.

 

Tomura’s five fingers clamped down hard around the thick, metal emitter shroud of Izuku’s lightsaber hilt.

 

"No!" Izuku shouted.

 

The effect was instantaneous. The brushed silver alloy instantly tarnished to a sickly, rusted brown. The metal began to flake and crumble away like dry earth. The decay raced down the hilt, eating through the outer casing, the focusing lenses, and heading straight for the exposed kyber chamber.

 

If the decay touched the crystal, it would shatter.

 

Panic flared in Izuku’s chest. He didn't think; he reacted. He channeled every ounce of Full Cowling into his right leg. With a blinding flash of green light, he drove his boot squarely into Tomura’s stomach.

 

The impact was like a cannon blast. Tomura’s eyes bulged, all the air rushing from his lungs as ribs cracked. He was launched backward, flying through the air and crashing violently into a stone pillar fifty yards away.

 

Izuku stood gasping, looking down at his weapon.

 

The emerald blade sputtered, flickered, and died with a sad hiss. The top half of his lightsaber hilt was entirely gone, crumbled to gray dust. The kyber chamber was exposed to the air, the green crystal inside pulsing erratically, humming with a pained, unstable resonance. The weapon was dead.

 

"Deku!"

 

Katsuki Bakugo dropped from the sky, landing heavily next to Izuku. The volatile Jedi Knight was battered, his robes scorched, holding his crackling orange lightsaber. "You idiot! Don't fight him in close quarters, you saw what he did to the tree!"

 

Before Izuku could respond, a new sound cut through the din of the battlefield. It was a low, thrumming vibration, coming from above.

 

A massive, triangular Sith Star Destroyer had broken through the cloud cover, hovering ominously over the Temple, blotting out the sun.

 

Down by the pillar, Tomura slowly rose to his feet. He was hunched over, coughing up blood, clutching his shattered ribs. But he was laughing. It was a raspy, unhinged sound that sent chills down Izuku’s spine.

 

"Game over," Tomura wheezed. "The boss has arrived."

 

Tomura reached into his robes and pulled out an object. It was another Sith Holocron, identical to the one Izuku had found on Othrys. Tomura dropped it onto the courtyard floor.

 

The pyramid activated. But this time, it didn't pull Izuku into a vision. Instead, it projected a massive, towering, fifty-foot-tall crimson hologram into the sky above the courtyard, visible to the entire city of Musutafu Prime.

 

The fighting across the Temple grounds ground to a halt. Jedi, Inquisitors, and Nomu alike stopped, looking up in awe and terror.

 

The hologram depicted a man sitting on a throne. He wore an elegant, dark suit rather than traditional Sith robes. His face above his upper lip was a ruin of scar tissue, completely devoid of eyes. A terrifying cybernetic rebreather masked his mouth.

 

Inhale... Exhale...

 

The mechanical breathing echoed from the Holocron, amplified a thousand times over, shaking the very foundations of the Temple.

 

"Citizens of the Republic. Members of the Jedi Order," the voice boomed. It was cultured, smooth, and dripping with an absolute, unquestionable authority. "Look upon your sanctuary. Look upon how easily it burns."

 

Izuku gripped his broken lightsaber hilt, his heart pounding in his chest. All For One.

 

"For a quarter of a century, you have lived under the delusion of peace, cultivated by a false Symbol," the Sith Lord continued. "Toshinori Yagi, the great All Might, led you to believe the dark side was vanquished. But the dark side cannot be destroyed. It is the inevitable entropy of the universe. It is the end of all things. It is the Rule of One."

 

The hologram’s eyeless face seemed to shift, panning down to look directly at the courtyard, directly at Izuku.

 

"The Jedi preach balance. They preach selflessness. But they hoard the light, denying it to the galaxy. I am the true inheritor of the Force. I take what I am owed, and I give it to those who serve me. I am the All For One."

 

A murmur of terror rippled through the surviving Jedi in the courtyard.

 

"I have returned to reclaim what was stolen from me," AFO’s voice darkened, vibrating with a localized anger that caused the air to physically heat up. "To the boy holding the broken green blade: You carry my brother's crystal. You wield a borrowed power, a pathetic echo of a ghost. I formally declare you my rival. Run. Hide. Train. It will not matter. I will strip the One For All from your corpse, and I will wipe its lineage from the stars."

 

The projection shifted back to a general address.

 

"This is not a war, Republic. This is an extermination. The age of the Jedi is over."

 

The hologram fizzled and vanished, leaving the courtyard in a stunning, horrified silence.

 

"Master!" Tomura shouted, sounding furious. "You said I could dust the boy!"

 

Suddenly, a massive, repulsorlift gunship adorned with Republic insignia broke through the smoke, its heavy repeating blasters spinning up. More Jedi reinforcements were arriving from the planetary garrisons, led by Master Shota Aizawa.

 

Tomura clicked his tongue in annoyance, wiping blood from his chin. He raised his hand, and a dark side portal—a swirl of purple-black smoke—opened behind him and the surviving Inquisitors.

 

"This was just the tutorial, player one," Tomura sneered at Izuku. "Enjoy the burning server."

 

Tomura stepped back into the portal, Dabi and Toga following close behind. The Nomu, entirely mindless, were left behind to fight to the death. The portals snapped shut, severing their presence from the Force.

 

The Siege of U.A. was over. But the nightmare had just begun.

 

 

 

Hours later, the fires were extinguished, but the damage was absolute.

 

The eastern and western wings of the Temple had been reduced to rubble. The grand archives were heavily damaged, and the courtyards were scarred by craters and scorch marks. Med-droids hovered over the wounded, their blue lights casting long shadows in the fading twilight.

 

Izuku sat on the edge of a medical cot in a makeshift triage center set up in the main hangar bay. A droid was wrapping a bacta-bandage around his bruised ribs. He was exhausted to his very core, his muscles aching with the violent after-effects of sustaining Full Cowling at thirty percent.

 

But physical pain was nothing compared to the heavy, crushing weight on his soul.

 

He stared at his hands. In his palms rested the broken pieces of his lightsaber hilt, and the naked, pulsing One For All kyber crystal. It felt warm, almost sad.

 

He had failed. The Temple was broken. The galaxy was terrified. And he, a newly knighted Jedi with no lightsaber, was the prime target of a Sith Lord older than the Republic itself.

 

"It hums a melancholic tune today, doesn't it?"

 

Izuku looked up.

 

Master Toshinori Yagi stood before him. The old man leaned heavily on his cane, looking more fragile than ever. The stress of the attack seemed to have aged him another ten years. He slowly lowered himself onto the cot next to Izuku, letting out a rattling cough.

 

"Master," Izuku whispered, his voice cracking. "I couldn't stop him. Tomura... he destroyed my weapon. He nearly killed me."

 

Toshinori placed a large, bony hand over Izuku’s trembling hands, enclosing the kyber crystal between them. "You survived, Izuku. You stood your ground against an assassin trained by the darkest entity in existence. That is a victory in itself."

 

"He called me his rival," Izuku said, looking into Toshinori’s sunken blue eyes. "He broadcasted it to the whole planet. Master... what does he mean by the 'Rule of One'? Why is he so obsessed with this crystal?"

 

Toshinori sighed, a long, weary sound that carried the weight of decades of sorrow. He looked out over the bustling hangar bay, but his eyes were seeing something far away.

 

"The Sith have always followed the Rule of Two," Toshinori began, his voice barely above a whisper. "A master, and an apprentice. One to embody the power, and one to crave it. But Darth Shigaraki is an aberration. He does not wish to share power, or pass it on. He wishes to hoard it all for himself. The Rule of One."

 

Toshinori pulled his hand away, resting it on his cane.

 

"Long ago, during the days of the Old Republic, Shigaraki was a powerful Sith Lord. But he discovered a dark side alchemy that broke the laws of nature. He learned how to sever a living being's connection to the Force, physically ripping their affinity out of their body and absorbing it into his own."

 

Izuku shuddered. "Like... stealing their midichlorians?"

 

"More than that," Toshinori said grimly. "He steals the very essence of their soul. If a Jedi could manipulate fire, Shigaraki took it. If a Jedi could heal, he took it. Over centuries, he amassed hundreds of stolen affinities, hiding in the shadows, extending his lifespan indefinitely. He became a god of the dark side. But there was one thing he could not control. His younger brother."

 

Izuku looked down at the green crystal. "The first user."

 

"Yes," Toshinori nodded. "His brother was a Jedi, but he was born sickly, seemingly with no affinity to the Force at all. Shigaraki, in a twisted act of pity and arrogance, forced a stolen affinity upon his brother—the ability to stockpile power. What Shigaraki did not know was that his brother did possess a latent affinity. An affinity so deep, so subtle, it was undetectable. The ability to transfer his own Force connection to another."

 

"The two affinities merged," Izuku realized, the pieces falling into place.

 

"Exactly," Toshinori said. "The stockpiling of power, and the ability to pass it on. One For All was born. It is the only power in the galaxy that cannot be stolen, because it must be willingly given. The younger brother infused his essence into this very kyber crystal, passing it to a successor, trusting that one day, the accumulated light would be strong enough to blind his brother's darkness."

 

Toshinori unbuttoned the collar of his robes, revealing a glimpse of the horrific, sprawling, cratered scar covering the left side of his chest.

 

"I was the eighth to wield the crystal," Toshinori said quietly. "Twenty-five years ago, I tracked Shigaraki to the ruins of Kamino Ward. We fought. It was a battle that shattered the planet's crust. I poured the combined strength of all seven previous masters into one final, devastating strike. I crushed his skull. I shattered his respiratory system. I thought I had ended him. But the cost was my own body, and my own connection to the Force. I became a husk, waiting to pass the crystal on to a worthy successor."

 

He looked at Izuku, his eyes shining with unshed tears. "I chose you, Izuku, because you knew what it was like to be powerless. You understand the true value of strength. But I have failed you. I passed a death sentence onto a child."

 

"No!" Izuku said sharply, standing up. The exhaustion was still there, but a new, fierce resolve burned in his chest. He gripped the naked kyber crystal tightly in his fist. "You didn't give me a death sentence, Master. You gave me a chance. A chance to protect people."

 

Toshinori looked up at the boy, his heart swelling with a bittersweet pride.

 

"The Temple is compromised," Izuku said, his voice steadying, taking on the tone of a true Jedi Knight. "If I stay here, All For One will send his armada to burn Musutafu Prime to the ground just to get to me. Millions will die."

 

"What are you proposing, Young Midoriya?"

 

"I need to leave," Izuku said. "I need to take the fight to him. Before he can amass his full fleet, we have to strike. Do we have the coordinates from the Holocron Tomura left behind?"

 

Toshinori’s eyes widened. "Izuku, that is suicide. Without a lightsaber, without mastering the crystal, you cannot face him."

 

"I won't be alone," a voice interrupted.

 

Izuku turned. Katsuki was standing behind them, his arms crossed over his chest, his orange lightsaber clipped to his belt. Next to him stood Shoto Todoroki and Tenya Iida, both looking battered but resolute.

 

"If you think you're flying off to fight the boogeyman by yourself, Deku, you're a bigger idiot than I thought," Katsuki growled.

 

"We stand with you, Midoriya," Iida said, adjusting his glasses. "The Jedi Order is not a building. It is the people. We will not let you face the dark side alone."

 

"The Holocron was encrypted," Shoto added calmly. "But Uraraka is in the slicer-bay right now. She managed to pull a partial flight log before the Holocron wiped its memory. The coordinates lead to the Outer Rim. A storm-covered ocean world."

 

"Kamino Ward," Toshinori breathed, his face paling. "He has returned to the place of our final battle. It is a trap, Izuku. He is luring you there."

 

"I know," Izuku said, looking down at the green crystal pulsing in his palm. "But it's a trap we have to spring. We can't wait for him to destroy the galaxy piece by piece. We have to cut the head off the snake."

 

Toshinori looked at the four young knights. He saw the fire in their eyes. He saw the same reckless, beautiful courage he had once possessed in his youth. He knew he could not stop them. It was the will of the Force.

 

The old Master stood up, leaning heavily on his cane. He reached into his robes and pulled out a small, metallic cylinder. It was an emergency distress beacon, heavily encrypted.

 

"If you are to walk into the shadows," Toshinori said, his voice firm, resonant with the ghost of the great All Might, "then you do not walk alone. I will accompany you. I may no longer wield the Force, but I know the terrain of Kamino Ward. I know how the monster thinks."

 

"Master, you can't," Izuku protested. "You're too weak, you—"

 

"I am your Master," Toshinori said, placing a hand on Izuku's shoulder, smiling warmly. "And it is the duty of the Master to see his Padawan through to the end. Go to the hangar. Prep a fast ship. The Gran Torino is fueled and ready. We leave within the hour."

 

As his friends rushed off to prepare the ship, Izuku lingered for a moment, looking at the broken pieces of his lightsaber. He slipped the kyber crystal into a secure pouch on his belt, letting the broken metal fall to the floor.

 

He didn't need a weapon to be a Jedi. He was the weapon.

 

Izuku turned and walked toward the hangar bays, the hum of the crystal echoing in his heart, preparing to plunge into the darkest abyss the galaxy had ever known.

 

 

 

Hyperspace was usually a place of comfort for Izuku. The swirling, infinite tunnel of mottled blue and white starlight moving past the viewport was a visual representation of the cosmic current. It was a reminder that the galaxy was vast, interconnected, and moving forward.

 

But aboard the Gran Torino, an aging, heavily modified Corellian light freighter, the starlight brought no comfort. The blue glow spilling into the cramped passenger hold only cast long, skeletal shadows across the faces of its occupants.

 

Izuku sat cross-legged on the cold deck plating, his eyes closed. In his lap rested a small, synth-leather pouch containing the naked, pulsing One For All kyber crystal. Without a lightsaber hilt to focus its energy, the crystal bled raw, unrefined Force resonance into the air. It felt like holding the beating heart of a star. It hummed against his thighs, a rhythmic, anxious vibration that matched the frantic beating of his own heart.

 

The ship rattled violently, the inertial dampeners struggling to compensate for the micro-fluctuations in the hyper-lane.

 

"Hold her steady, Bakugo!" Tenya Iida’s voice barked from the co-pilot’s chair in the cockpit just a few meters away.

 

"Don't tell me how to fly my own ship, Four-Eyes!" Katsuki Bakugo snarled back, his hands dancing across the yoke and throttle controls with frantic precision. "This bucket of bolts hasn't had her hyperdrive calibrated since the Mandalorian Wars. If you want a smoother ride, get out and push!"

 

"The nav-computer is struggling with the coordinates," Shoto Todoroki observed quietly, leaning over the sensor readouts. "The space surrounding the Kamino Ward sector is riddled with ion storms and gravitational anomalies. It's masking our approach, but it's also making descent nearly impossible."

 

"Nothing is impossible," Katsuki gritted out, the orange glow of the console highlighting the feral determination in his crimson eyes. "We punch through the storms, we drop the landing gear, and we kick the Sith's teeth in. Simple."

 

Izuku slowly opened his eyes, the emerald light of the crystal casting a faint glow on his freckled face. He looked across the small hold.

 

Master Toshinori sat strapped into a crash web against the bulkhead. The former Symbol of Peace looked worse than he had on Coruscant. The sheer proximity to the dark side—growing stronger the closer they got to their destination—seemed to be physically eating away at him. He was pale, his breathing labored and shallow, his eyes sunken deep into his skull. Yet, beneath the frailty, there was an immovable bedrock of resolve. He held no lightsaber, wore no armor. He was draped only in the simple, earthen robes of a Jedi ascetic.

 

"Master," Izuku whispered, his voice barely cutting through the hum of the hyperdrive. "You should be resting. The atmospheric entry is going to be rough."

 

Toshinori opened one brilliant blue eye. He offered a weak, reassuring smile that didn't quite reach the hollows of his cheeks. "A Jedi does not rest when the galaxy bleeds, my boy. Besides, the dark side is already clawing at the hull of this ship. I am centering myself. You should do the same. Do not let his shadow extinguish your light before we have even arrived."

 

"I don't have a weapon," Izuku admitted, looking down at the pouch. The shame of losing his lightsaber hilt to Tomura’s decay still burned hot in his chest. "I have the crystal, but I can't project a blade. If I have to face him..."

 

"A Jedi is not his lightsaber," Toshinori interrupted gently, his voice rasping. "The blade is merely a tool. A focus. Your body, your spirit, your connection to the living Force—that is your true weapon. One For All does not reside in the kyber, Izuku. It resides in you. The crystal is just the bridge."

 

Before Izuku could internalize the lesson, the ship’s proximity alarms began to scream in a deafening, rhythmic wail.

 

"Dropping out of hyperspace in three, two, one!" Katsuki yelled.

 

He wrenched back on the hyperdrive levers. The swirling blue tunnel outside the viewport snapped abruptly into the stark, terrifying reality of real-space.

 

Instantly, the Gran Torino was thrown into a violent spin.

 

"Brace!" Uraraka screamed from the engineering station, using her gravity affinity to anchor herself to the deck plates.

 

Izuku hit the bulkhead, the impact knocking the wind from his lungs. He instinctively channeled a fraction of Full Cowling to anchor his boots magnetically to the floor, grabbing Toshinori’s crash web to ensure the old man wasn't thrown loose.

 

Outside the viewport, there was no stars. There was no sky. There was only absolute, raging chaos.

 

Kamino Ward was a nightmare of atmospheric engineering. The planet was entirely covered in a violently tempestuous ocean. The skies were pitch black, choked with thick, swirling cumulonimbus clouds that flashed violently with jagged forks of violet and blood-red lightning. The wind sheer hit the freighter like the fist of an angry god, throwing it sideways.

 

"Stabilizers are shot!" Iida yelled over the roaring of the hull. "Altitude is dropping too fast! We're going to hit the water!"

 

"Like hell we are!" Katsuki roared. He slammed his fist into the console, simultaneously channeling his own Force combustion into the ship's thruster relays. The engines flared with an unnatural, blinding orange light, giving the ship the exact burst of acceleration it needed to pull up from a fatal nose-dive.

 

Through the lashing rain and the spray of the black ocean below, a structure began to materialize in the gloom.

 

It was a monolithic installation, built upon massive, cylindrical durasteel stilts that plunged deep into the churning sea. The facility itself was shaped like a massive, flattened disk, bristling with communication spires and heavy turbolaser batteries. It was entirely dark, save for the sickly red glow of landing strip lights.

 

"That's it," Todoroki said, his eyes narrowing. "The coordinates match perfectly. But I'm not reading any life signs. No thermal signatures on the exterior. It's a ghost town."

 

"It's not empty," Izuku whispered.

 

Even through the thick hull of the ship, Izuku could feel it. The dark side here was not an ambient presence; it was a physical weight, crushing the breath from his lungs. It felt like drowning in an ocean of frozen tar. The malice radiating from the facility was so potent, it made the One For All crystal in his pouch vibrate violently, emitting a high-pitched, pained whine that only Izuku and Toshinori could hear.

 

"Set her down on the outer eastern platform, Bakugo," Toshinori commanded, his voice suddenly sharp, clear, and devoid of frailty. He was drawing on the Force, using it to temporarily hold his shattered body together. "Keep the engines hot. You four will remain on the ship. Keep the comms open."

 

"Like hell!" Katsuki snapped, swinging his chair around. "We're not staying behind while you two march into a meat grinder!"

 

"This is not a negotiation, Knight Bakugo," Toshinori said, his tone brokering absolute authority. "Darth Shigaraki's presence is a vacuum. If he engages you, he will rip your Force affinities from your bodies. He will steal your combustion, your ice, your speed, and your gravity. You will become fuel for his empire. Izuku is the only one immune to his theft."

 

Katsuki looked like he wanted to argue, his jaw clenched so tight his teeth ground audibly, but he saw the grim reality in the old Master's eyes. He slammed his hand against the console. "Fine. But if things go south, I'm blowing a hole in that base and dragging your asses out."

 

The Gran Torino touched down roughly on the rain-slicked durasteel platform, the landing gear groaning under the weight.

 

Izuku stood up, pulling his hood over his head. The rain was already lashing against the primary airlock door. He looked at Uraraka, who gave him a terrified, brave smile, then at Todoroki and Iida, who both nodded solemnly.

 

"May the Force be with you," Iida said quietly.

 

Izuku nodded. He turned to Toshinori. The old Master stood tall, holding his wooden cane, the wind from the opening airlock whipping his earthen robes around his frail form.

 

"Together, Young Midoriya," Toshinori said.

 

They stepped out into the storm.

 

The rain was freezing, stinging Izuku’s cheeks like needles. The roar of the ocean below was deafening, the waves crashing against the massive stilts of the facility with enough force to shake the platform.

 

The entrance to the facility was a set of massive, blast-proof doors. Izuku didn't bother looking for a control panel. He raised his hand, channeling a focused burst of kinetic Force energy, and shoved. The heavy doors groaned, the locking mechanisms snapping, and slid open with a screech of tortured metal.

 

They stepped out of the storm and into the belly of the beast.

 

The interior of the cloning facility was completely devoid of warmth. The walls were constructed of stark, seamless white plastoid, illuminated by harsh, sterile fluorescent strips that cast no shadows. It was a labyrinth of clinical perfection, reeking of ozone, antiseptics, and the unmistakable metallic tang of blood.

 

They moved silently through the corridors. Izuku kept his senses wide open, his Danger Sense buzzing like an angry hornet in the back of his skull. Yet, they encountered no resistance. No battle droids. No Sith Inquisitors. No Nomu.

 

"It's too quiet," Izuku murmured, his hand hovering over the pouch at his belt. "He knows we're here. The Holocron was a direct invitation. Why isn't he attacking?"

 

"Because he is a predator who enjoys the fear of his prey," Toshinori replied, his eyes scanning the corridor. "He is drawing us deeper into his web. He wants us isolated. Keep your mind guarded, Izuku. Do not let his whispers penetrate your focus."

 

They passed through a set of secondary blast doors and entered the primary processing wing.

 

Izuku stopped dead in his tracks, the breath catching in his throat.

 

It was a cavernous chamber, stretching for miles in every direction. The floor was a grid of catwalks suspended over an endless abyss of machinery. But it was what filled the chamber that made Izuku’s blood run cold.

 

Suspended from the ceiling, stretching infinitely into the dark, were thousands upon thousands of cylindrical bacta vats. Inside each one floated a Nomu. Some were fully formed—hulking, multi-limbed monstrosities with exposed brains. Others were in earlier stages of horrific gestation, their bodies a twisted mess of spliced genetics and dark side alchemy.

 

"The missing children," Izuku choked out, horrified. "The stolen Force affinities. Master... he's not just building an army. He's building an armada of abominations. He's weaponizing the Force on an industrial scale."

 

"This is his grand design," Toshinori said, a deep sorrow lacing his words. "He strips the galaxy of its individuality, of its connection to the Light, and churns out mindless slaves bound only to his will."

 

Suddenly, the Danger Sense in Izuku's mind didn't just buzz; it screamed. It was a spike of psychic agony so intense it forced Izuku to his knees, clutching his temples.

 

"Izuku!" Toshinori cried.

 

CLANG!

 

A massive, heavy durasteel blast door slammed down from the ceiling directly between them.

 

Izuku looked up, horror washing over him. He was trapped on a narrow observation gantry, while Toshinori was sealed inside the main processing chamber.

 

"Master!" Izuku yelled, scrambling to his feet. He threw his hands forward, channeling a massive wave of kinetic Force. The blast hit the metal door with the force of a detonator, but the door didn't even dent. A shimmering, crimson ray-shield activated over the metal, absorbing the kinetic energy and dissipating it.

 

"Izuku, stand back!" Toshinori yelled from the other side.

 

Izuku pressed his hands against the transpari-steel viewing window set into the wall beside the door. He could see Toshinori in the vast, empty space between the cloning vats.

 

The lights in the main chamber began to flicker and die, plunging Toshinori into darkness. The only illumination came from the sickly purple glow of the Nomu vats.

 

And then, the temperature in the room plummeted. The condensation on the viewing window froze over.

 

From the shadows of the processing chamber, a figure detached itself.

 

He seemed to glide across the floor, his feet making no sound. He was tall, dressed in a sharply tailored, immaculate black suit. His face was entirely obscured by a massive, industrial black helmet that connected to a series of heavy life-support tubes snaking down his spine.

 

Inhale... Exhale...

 

The mechanical breathing was no longer a hologram. It was real. It vibrated through the floorboards, rattling the bones in Izuku’s body.

 

Darth Shigaraki. All For One.

 

Toshinori did not reach for a weapon. He simply stood tall, planting his cane firmly on the deck plates. Despite his frail, skeletal appearance, the Force swirled around him like a raging typhoon of pure, blinding light. For a moment, the gaunt, sick old man vanished, replaced by the imposing, mythic aura of All Might.

 

"Toshinori," All For One spoke. The voice was smooth, cultured, and dripping with an insidious, mocking affection. "You have aged poorly. The years without the Force have withered you down to the bone. It is almost tragic to look upon the mighty Symbol of Peace, reduced to a trembling old man with a stick."

 

"And yet," Toshinori replied, his voice booming with the resonant authority of a Jedi Master, "I can still look at the stars with my own eyes, Shigaraki. You hide behind a mask, breathing borrowed air, kept alive by the stolen lifeblood of innocents. You are a parasite."

 

All For One chuckled, a deep, vibrating sound. "Morality. The last refuge of the weak. I have lived for millennia. I have seen Republics rise and fall. I have watched Jedi Grand Masters turn to dust. I am the eternal constant. And you? You are a dying ember, foolishly trying to ignite a damp log."

 

The Sith Lord slowly turned his helmeted head, looking through the transpari-steel window directly at Izuku. Even without eyes, Izuku felt the crushing weight of his gaze.

 

"And here is the new vessel," AFO mused. "A boy who was born empty. How fitting. The crystal of my brother, passed down to a child who relies on the strength of ghosts. He cannot save you, Toshinori. Watch."

 

All For One raised his right hand.

 

He didn't ignite a lightsaber. He didn't need to.

 

From his fingertips, a torrent of Force lightning erupted. But it wasn't the jagged, chaotic blue electricity of standard dark side manipulation. It was a thick, volatile crimson—a specialized, lethal affinity stolen from a fallen Jedi generations ago. The red lightning tore across the chamber, screaming through the air, aimed directly at Toshinori’s chest.

 

Toshinori didn't flinch. He raised his bare left hand.

 

He did not possess his own Force affinity anymore; he had given it to Izuku. But he was still a Master of the fundamental arts. He reached out and grasped the fabric of the Force itself. The air in front of him solidified into a shimmering, translucent barrier of pure Light side energy.

 

The crimson lightning slammed into the barrier. The impact was deafening, illuminating the chamber in a blinding flash of red and white. Toshinori’s boots slid backward on the metal grating, his teeth gritted, the veins bulging on his pale forehead. He held the blast, redirecting the lethal energy into the floor, where it melted through the durasteel grates.

 

"Master!" Izuku screamed, slamming his fists against the glass. He channeled Full Cowling into his arms, pulling back and striking the ray-shielded door with ten percent, then twenty percent of his power. CRACK! His knuckles bled, the bones protesting, but the Sith-forged door did not yield.

 

"Impressive," All For One mocked, lowering his hand. The lightning ceased. "You remember the old forms. A kinetic shield. But how long can a shattered vessel contain the ocean?"

 

The Sith Lord vanished.

 

He didn't run; he used a stolen teleportation affinity to fold space, instantly reappearing directly behind Toshinori.

 

Toshinori spun, swinging his heavy wooden cane like a lightsaber. He infused the wood with Force energy, making it as hard as beskar. The cane struck All For One’s shoulder, but the Sith Lord didn't even stagger.

 

All For One merely reached out and caught the cane with his left hand. The wood instantly began to turn black, rotting away into dust—the same decaying affinity he had taught his apprentice, Tomura.

 

With his right hand, All For One delivered a devastating, open-palm strike to Toshinori’s chest.

 

It wasn't just a physical blow. It was a telekinetic battering ram. The impact shattered Toshinori’s ribs and sent him flying backward. He crashed violently into one of the massive Nomu vats, the transpari-steel cracking under the force of his frail body. Toshinori collapsed to the floor in a heap, violently coughing up a spray of crimson blood that stained his white beard.

 

"NO!" Izuku roared. Green lightning arched wildly across his body, his eyes glowing with an emerald fury. He drew his arm back, preparing to unleash one hundred percent of One For All against the glass, consequences to his own body be damned.

 

"Izuku... stop!" Toshinori gasped, raising a trembling hand.

 

Through their Force bond, the old Master projected a feeling of absolute calm, arresting Izuku’s rage.

 

Do not give into the anger, Toshinori’s voice echoed in Izuku’s mind. Anger is his domain. If you strike out of hatred, you become his pawn. Watch. Learn.

 

Toshinori slowly, painfully pushed himself to his feet. His body was broken, but his spirit blazed like a supernova. The sheer purity of his Light side presence began to push back the encroaching cold of the room. The flickering lights stabilized. The purple vats seemed to dim.

 

"You always were a stubborn fool, Toshinori," All For One sighed, though there was a hint of genuine irritation in his mechanical voice. "Nana Shimura was the same. Your master fought me with a smile on her face, right up until the moment I tore her gravity affinity from her spine and watched her bleed to death in the dirt."

 

At the mention of his master, Toshinori didn't give into rage. He merely smiled. It was a bloody, broken smile, but it was radiant.

 

"Nana pitied you, Shigaraki," Toshinori said softly. "She saw you for what you truly are. A terrified child, hoarding toys because you are afraid of the dark."

 

All For One’s aura flared violently, the temperature in the room spiking. "I AM THE DARK!"

 

The Sith Lord raised both hands, and the chamber erupted.

 

He unleashed a horrifying amalgamation of stolen powers simultaneously. A torrent of blistering blue pyrokinesis, jagged crimson lightning, and a localized gravity crush aimed directly at Toshinori. It was an attack that could have leveled a small city, compressed into a singular, devastating point of execution.

 

Toshinori Yagi did not raise a shield. He did not attempt to dodge.

 

He stood tall, closed his eyes, and opened his arms, embracing the currents of the living Force.

 

The attack hit him.

 

The explosion of dark energy was blinding, blowing out the transpari-steel window in front of Izuku. Izuku was thrown backward, shielding his face from the intense heat and the shockwave of the blast.

 

When the smoke finally cleared, Izuku scrambled to the shattered window, his heart stopping in his chest.

 

Toshinori was gone.

 

There was no body. There was no blood. There were only his earthen-brown Jedi robes, empty and slightly scorched, fluttering gently to the grated floor. In the moment of his death, Toshinori Yagi had completely surrendered his physical form to the Force, achieving a state of spiritual transcendence known only to the greatest of Jedi Masters.

 

Izuku stared at the empty robes. The world around him went entirely, perfectly silent.

 

The humming of the machinery faded. The roaring of the storm outside vanished. The beating of his own heart stopped. There was only a profound, bottomless void where the presence of his father-figure had once been.

 

The heavy blast door separating the observation deck from the main chamber slowly hissed open.

 

All For One stood amidst the smoke, his black suit pristine, untouched by the devastation he had wrought. He looked at the empty robes, tilting his helmeted head in mild annoyance.

 

"The coward's exit," All For One murmured. "Fading into the ether to deny me the pleasure of breaking his body one final time. Tragic."

 

He turned slowly, his eyeless mask locking onto the boy kneeling in the shattered glass.

 

"Well, little vessel. The ghost is gone. It is just you and me."

 

The silence in Izuku’s mind shattered.

 

It was replaced by a sound he had never heard before. It was a roar—a primal, deafening roar of absolute, unadulterated anguish. It was the sound of his own soul tearing in half.

 

The One For All crystal in his pouch resonated with his grief. It didn't just glow; it flared with blinding, radioactive intensity.

 

Izuku didn't channel Full Cowling. He let it consume him.

 

Brilliant, violent arcs of green and black lightning erupted from Izuku's body. The stone and metal beneath him disintegrated as he pushed off the ground, leaving a crater behind. He crossed the distance to the Sith Lord in a fraction of a microsecond, moving faster than humanly possible.

 

Izuku unleashed a barrage of physical strikes, his fists moving so fast they created sonic booms within the chamber. He didn't use a lightsaber; he used his body as a kinetic warhead.

 

Detroit Smash!

 

Izuku’s fist slammed squarely into All For One’s chest. The kinetic force of the blow was equivalent to a turbolaser strike. A shockwave rippled out, shattering every Nomu vat within a hundred-yard radius, sending the purple fluid and grotesque bodies washing over the floor.

 

But All For One did not move.

 

The Sith Lord hadn't even flinched. He stood perfectly still, Izuku’s fist pressed against his chest. A shimmering, microscopic barrier of compressed kinetic-reflection energy surrounded the Sith Lord's body. He had absorbed the entire impact.

 

"Is that it?" All For One asked, his voice dripping with condescension.

 

Before Izuku could recoil, All For One moved. His hand shot out, moving with a lazy, inevitable speed that defied the laws of physics, and grabbed Izuku by the throat.

 

The dark side flooded into Izuku’s body, cold and agonizing, freezing the Full Cowling lightning in its tracks. Izuku gasped, his hands clawing uselessly at the Sith Lord’s indestructible grip.

 

All For One lifted the boy off the floor effortlessly, holding him at eye level.

 

"You fight like a brawler," AFO criticized, tightening his grip, crushing Izuku’s windpipe. "You have inherited the greatest power in the galaxy, the culmination of eight lifetimes, and you use it to throw punches. You are a child wielding a star destroyer as a club."

 

Izuku kicked out, driving both his boots into the Sith Lord’s stomach, but it was like kicking a durasteel bulkhead. The pain merely rebounded up his own legs.

 

"Toshinori was a fool to choose you. You have no finesse. No understanding of the deeper currents of the Force. You are merely a meat-shield for a crystal that belongs to me."

 

With a casual flick of his wrist, All For One hurled Izuku across the chamber.

 

Izuku flew through the air like a ragdoll, crashing through two massive steel pillars before slamming into the far wall. He hit the ground hard, his left arm snapping with a sickening crunch. He coughed up blood, his vision swimming, the pain threatening to drag him into unconsciousness.

 

He tried to push himself up, his right arm trembling violently. He couldn't give up. Toshinori had died to protect him. He had to fight.

 

Stomp. Stomp.

 

All For One was walking toward him slowly. The Sith Lord raised a hand.

 

Izuku felt an invisible, crushing weight slam into his body. It was a telekinetic pin, so powerful it drove him flat against the grating, cracking the metal beneath him. He couldn't move a muscle. He couldn't even expand his lungs to scream.

 

"I told you, boy. The age of the Jedi is over."

 

All For One stood over him, an imposing monolith of darkness. He extended two fingers.

 

The synth-leather pouch at Izuku’s belt tore open. The naked, pulsing green One For All crystal floated out, levitating into the air between them.

 

The crystal was humming wildly, flashing erratically. To Izuku, it felt like the crystal was screaming in terror.

 

All For One looked at the glowing gem. The mechanical breathing hitched for just a fraction of a second, revealing a deeply buried, ancient emotion.

 

"Little brother," All For One whispered, the mockery gone, replaced by a chilling, obsessive melancholy. "You have run for so long. You have hidden behind these pathetic, self-righteous fools. You defied me. But your rebellion ends today. The spark returns to the void."

 

"No..." Izuku choked out, blood spilling from his lips. He poured every ounce of his remaining willpower into reaching for the crystal with the Force, trying to pull it back.

 

But his connection was a thread compared to the Sith Lord's massive cables of dark energy.

 

All For One slowly closed his fist.

 

The telekinetic pressure on the crystal increased exponentially. The green gem began to whine, a high-pitched, agonizing sound that felt like glass shattering inside Izuku’s brain.

 

"Die."

 

All For One clenched his fist tight.

 

CRACK.

 

The One For All kyber crystal shattered.

 

It exploded into a thousand tiny, lifeless shards of green glass that rained down upon the floor. The emerald light extinguished instantly. The deep, kinetic heartbeat that had resonated in Izuku’s soul for years stopped.

 

The psychic backlash was instantaneous and catastrophic.

 

Izuku felt a massive, vital part of his own soul tear away. The connection to the past masters, the wellspring of power, the comforting warmth of the Light—it was all gone. Plunged into a sudden, absolute sensory deprivation, Izuku’s mind fractured. He let out a silent, ragged scream, his eyes rolling back in his head as he collapsed into the darkness of profound shock.

 

All For One looked down at the shards of the crystal, then at the broken, unconscious boy.

 

"It is done," the Sith Lord murmured. He raised his hand, gathering a ball of crimson lightning to deliver the executing blow to Izuku’s motionless body. "Rest now, vessel."

 

BOOOOOOOOOOM!

 

The entire western wall of the facility suddenly exploded inward.

 

A massive shower of transpari-steel, durasteel plating, and freezing rain erupted into the chamber. Riding the shockwave of the explosion, the Gran Torino smashed directly into the facility, its heavy landing gear tearing up the floor grates.

 

Katsuki Bakugo stood on the lowered boarding ramp, his eyes blazing with a feral, unhinged fury. He didn't use a lightsaber. He extended both hands, channeling every ounce of his combustion affinity.

 

"AP SHOT: AUTO-CANNON!"

 

A rapid-fire barrage of highly concentrated, armor-piercing kinetic explosions erupted from Bakugo’s palms. The blasts rained down on All For One like a meteor shower, forcing the Sith Lord to drop his lightning and raise a telekinetic shield to absorb the devastating bombardment.

 

While the Sith Lord was blinded by the explosions, Shoto Todoroki stepped onto the ramp beside Bakugo.

 

Todoroki placed both hands on the floor of the ramp. A massive, absolute-zero glacier of ice erupted outward, surging across the floor of the facility. It enveloped All For One, freezing the Sith Lord in a localized iceberg the size of a building.

 

"Uraraka, now!" Iida yelled from the cockpit.

 

Ochaco Uraraka leaned out of the airlock, tears streaming down her face as she saw Toshinori's empty robes, and the broken, bloody body of Izuku. She thrust her hands forward, targeting Izuku.

 

Zero Gravity!

 

Izuku’s unconscious body floated off the floor. Uraraka yanked her arms backward, using a localized gravity well to pull Izuku rapidly through the air and directly into her arms on the ship's ramp.

 

"We have him! Go, go, go!" Uraraka screamed, dragging Izuku into the hold.

 

"Hold on!" Katsuki roared, sprinting up the ramp as it sealed shut.

 

In the cockpit, Iida slammed the throttle to the absolute maximum. The Gran Torino’s engines screamed in protest, venting plasma as the ship tore itself out of the ruined facility, reversing violently back out into the raging storm.

 

Behind them, the massive iceberg in the cloning chamber exploded.

 

All For One emerged, completely unharmed, shaking the ice from his shoulders. He walked slowly to the jagged hole in the wall, watching the Gran Torino blast through the atmosphere and break orbit.

 

The Sith Lord did not attempt to pull the ship back. He did not summon his fleet to pursue.

 

He merely stood in the howling wind and rain, looking down at the lifeless shards of green kyber scattered across the floor. He slowly reached down and picked up a single, dull shard, holding it between his pale fingers.

 

"Run, little children," All For One whispered to the storm, a cruel, satisfied smile hidden beneath his mask. "The spark is dead. The galaxy is mine."

 

 

 

Aboard the Gran Torino, the silence in the passenger hold was absolute, save for the rhythmic humming of the hyperdrive and the soft, ragged breathing of the boy on the medical cot.

 

They had jumped blindly into hyperspace, putting as much distance between themselves and Kamino Ward as possible.

 

Izuku lay on the cot, his broken arm set in a splint, his bruised face pale and sweaty. He was unconscious, locked in a deep, traumatic coma.

 

Ochaco sat beside him, gently wiping the blood from his forehead with a damp cloth. She was crying silently, the tears falling onto Izuku’s motionless chest.

 

Shoto stood in the corner, staring blankly at the wall, the trauma of the encounter freezing his usually stoic demeanor. Iida remained in the pilot's seat, staring out into the blue tunnel of hyperspace, his knuckles white as he gripped the yoke.

 

Katsuki stood in the center of the hold. He was staring down at his hands, trembling with a mixture of profound rage and a terrifying, unfamiliar feeling: absolute helplessness.

 

They had lost the Symbol of Peace. They had lost the One For All crystal.

 

The age of the Jedi was over. The shadow had won.
