Chapter 3: The Abomination, the Zealot, and the Echo of the Spire
The heavy, rusted blast doors of Dr. Ujiko's forgotten laboratory did not slide open smoothly. They ground against their tracks with a shrieking, metallic wail that vibrated in the marrow of Class Zero's bones.
At the bottom of the collapsed sinkhole, the only light came from the glowing, high-pressure sphere of water hovering above Kota Izumi's palm. It cast long, terrifying shadows into the pitch-black corridor beyond the doors.
The stench hit them first. It wasn't the smell of decay or the toxic ash of the surface. It was the sterile, chemical reek of formaldehyde, ozone, and stagnant, bio-engineered blood.
Then came the sound. A wet, heavy, dragging noise, accompanied by a low, multi-toned gurgle.
From the shadows of the corridor, a massive hand reached out and gripped the edge of the blast door. The fingers were disproportionately long, ending in jagged, bone-white talons. The creature pulled itself into the dim light of Kota's water sphere.
It was a Prototype Nomu.
Unlike the sleek, combat-perfected High-Ends that had assaulted Aegis Prime, this monstrosity was an early, imperfect draft of Dr. Ujiko's nightmares. Its muscular structure was asymmetrical, its left arm dragging heavily on the grated floor. Its exposed brain pulsed erratically beneath a cracked, translucent dome. Multiple, mismatched Quirk factors were visibly fighting for dominance within its biology, causing its flesh to spasm and weep thick, black fluid.
But its eyes—three bulbous, unblinking yellow orbs—were locked entirely on the three teenagers.
"Oh, god," Katsuma Shimano whispered, his datapad slipping from his trembling fingers. He took a terrified step backward, his Cell Activation Quirk instinctively sensing the horrific, unnatural biology of the creature. "It's not dead. It's just... it's been sleeping."
"Stand behind me!" Kota roared. The sheer terror in his chest instantly transmuted into volatile, desperate anger. He thrust his hands forward, condensing the ambient moisture in the cold subterranean air. "Water Jet: Piercing Cannon!"
A highly pressurized, razor-thin beam of water erupted from Kota's palms, striking the Prototype Nomu directly in the center of its exposed chest. The kinetic force was enough to punch through solid concrete.
The beam hit the creature's flesh and violently splashed outward. The Nomu didn't even flinch. Its mismatched, hyper-dense muscle fibers effortlessly absorbed the impact.
The Prototype tilted its head, its jaw unhinging to reveal rows of jagged, metallic teeth. It let out a deafening, multi-vocal screech that echoed off the steel walls, and it lunged.
"Kota, move!"
Eri didn't use her Rewind. She used her training. She lunged forward, tackling Kota around the waist and driving them both into the mud just as the Nomu's massive talons swiped through the space where Kota's head had been a microsecond prior. The sheer wind pressure from the swing shattered the rocks behind them.
"We can't fight that!" Eri screamed, hauling Kota to his feet. She grabbed Katsuma by the back of his tactical vest. "Aizawa-sensei said we run from S-Rank threats! Move into the corridor! Now!"
"Into the lab?!" Kota yelled, scrambling to his feet as the Nomu recovered its balance. "We'll be trapped!"
"The dirt ramp collapsed! We can't climb out, and it's too fast!" Eri commanded, her red eyes blazing with the fierce, unyielding resolve she had learned from Izuku Midoriya. "There has to be a secondary exit or a fortified control room! Run!"
Class Zero sprinted past the massive blast doors, plunging headlong into the pitch-black, labyrinthine corridors of the abandoned laboratory. Behind them, the Prototype Nomu let out another horrific screech, its heavy, mismatched footsteps pounding against the steel grating as the hunt began.
The Surface World. Hope's Ridge.
While the children fled into the dark below, the reformed sinners fought for their lives in the rain above.
The copycat killer known as 'The Purge' did not attack the settlement with a grand, theatrical entrance. He struck like a ghost, utilizing the blinding, freezing sleet and the encroaching twilight to his absolute advantage.
Kurogane, the towering, scaled man who had confronted Class Zero earlier, was patrolling the southern perimeter of the camp. His heavy logging axe rested on his shoulder. He paused, sniffing the air, his reptilian eyes narrowing. He smelled ozone and gunpowder.
FSSST.
The sound was barely a whisper. A high-velocity, armor-piercing round—fired from a silenced, pre-war Commission sniper rifle—tore through the rain. It struck Kurogane in the right shoulder, shattering his collarbone and completely bypassing his hardened scales.
Kurogane roared in agony, dropping his massive axe into the mud.
Before he could shout a warning to the camp, a figure dropped from the canopy of a nearby pine tree. The Purge wore a sleek, tactical stealth suit, his face completely obscured by a smooth, featureless ballistic mask painted with a jagged, blood-red grin—a sickening homage to the Hero Killer's scarf.
The Purge landed silently behind the massive scaled man. He drew a serrated, eight-inch hunting knife. He didn't aim for the armor; he aimed for the unscaled, vulnerable flesh beneath Kurogane's jaw.
"False idols bleed," The Purge whispered, driving the blade upward.
CLANG!
The hunting knife did not pierce flesh. It struck a solid, jagged piece of steel that had seemingly materialized out of the shadows.
The Purge blinked behind his mask, his momentum entirely halted.
Standing between the killer and the wounded Kurogane was Chizome Akaguro. Stain had not run. He had closed the twenty-mile gap through the mountains at a dead, lung-burning sprint, pushing his Quirkless body to the absolute brink of human endurance.
Stain's own combat knife was locked against the serrated blade of the copycat.
"You use my words, little boy," Stain growled, his white, pupilless eyes burning with a terrifying, unadulterated wrath as he stared down the fanatic. "But you do not understand the text."
The Purge's eyes widened behind his mask. "The Hero Killer... You're alive."
"I am the Hound," Stain corrected.
Stain didn't rely on Bloodcurdle. He used pure, brutal leverage. He twisted his wrist, disarming the copycat's knife, and delivered a devastating, spinning roundhouse kick directly to the side of the Purge's knee. The joint cracked, and the killer stumbled backward into the mud.
"Intruder!" Kurogane finally roared, clutching his bleeding shoulder.
The settlement of Hope's Ridge instantly erupted into chaos. Alarms blared. The reformed Tartarus inmates and PLF soldiers burst from their cabins, their Quirks flaring. Fire, telekinesis, and mutant appendages illuminated the freezing rain.
But The Purge was not alone, and he was not unprepared.
"The sinners are awake!" The Purge yelled, rolling backward and pulling a detonator from his belt. "Cleanse the valley!"
He pressed the button.
All around the perimeter of Hope's Ridge, a dozen pre-war directional fragmentation mines—identical to the one Nagant had disabled on the bridge—detonated simultaneously.
The explosions tore through the tree line, sending massive waves of shrapnel and concussive force into the settlement. Several cabins splintered instantly. The reformed villains, caught off guard by the military-grade explosives, were thrown violently into the mud.
From the shadows of the tree line, half a dozen more fanatics emerged. They were dressed in the same stealth suits, armed with high-powered Commission assault rifles. The Purge wasn't just a serial killer; he had amassed a cult of followers who believed the Sovereign's mercy was a plague.
They opened fire on the disoriented settlement.
"Get to cover!" screamed the woman with the radioactive green eyes, projecting a massive, translucent energy shield to block a volley of bullets from tearing into a group of unarmed civilians.
The Purge recovered his footing, drawing a secondary combat blade. He looked at Stain, his fanatical eyes burning behind the mask. "You were the true blade of justice, Chizome! You purged the fakes! And now you stand here, defending the rot?! The Sovereign broke you!"
"The Sovereign gave me clarity," Stain retorted, dropping into a low, lethal combat stance.
The Purge charged, his blade moving in a frantic, highly-trained flurry of strikes. Stain parried, dodged, and deflected. Every muscle in his Quirkless body screamed with the exertion. He was fighting a man heavily armed and deeply entrenched in the zealotry Stain himself had invented. It was like fighting a horrific, distorted mirror.
Above the chaotic melee, perched on the sheer, rocky cliff overlooking the valley, Lady Nagant finally found her vantage point.
The freezing rain whipped her white-and-purple hair. Her right arm, fully morphed into the Swarm Rifle, rested steadily against a boulder. Her sniper's vision cut through the smoke, the explosions, and the darkness.
She saw the six heavily armed fanatics pinning down the reformed villains.
"Spire Command is still jammed," Nagant muttered to herself, her finger resting lightly on the trigger. "No backup. Just the Hound and the Sniper."
She inhaled the freezing air. She exhaled her hesitation.
BANG. BANG. BANG.
Three hyper-velocity rounds tore through the valley in less than a second. Nagant didn't aim for center mass; she aimed for the weapons. The assault rifles of three different fanatics were violently, flawlessly shattered in their hands, the kinetic impact throwing the zealots to the ground.
"Sniper on the ridge!" one of the remaining fanatics screamed, pointing up at the cliff.
"I see everything," Nagant whispered coldly, cycling the next round.
Aegis Prime. The Sovereign's Spire.
The central command hub was usually a sanctuary of calm, iridescent blue light. Tonight, the hard-light terminals were flashing a violent, erratic yellow.
Rei Arata—the Winged Sovereign—stood at the center of the war table. He wore his silver moth-mask, his hands planted firmly on the console. Rin (GateL0ck) was frantically typing beside him, blood dripping from her nose as she fought against a massive spatial distortion.
"The comms relay in Sector 4 of the Oku-Hida range is completely dead, Sovereign!" Rin reported, her voice tight with panic. "I can't reach Class Zero, and I've lost the telemetry on Hound-One! There is a massive, localized electromagnetic anomaly blocking the Astral Nexus signals."
Shota Aizawa stood on the opposite side of the table. His visible eye was wide with a terrifying, paternal dread that he rarely allowed to surface.
"The anomaly isn't natural," Aizawa growled, his hands gripping his capture scarf. "Ujiko had dozens of hidden black-sites scattered across the mountains before the war. If the terrain shifted, it might have exposed one. Sovereign, if Eri is trapped in a Nomu facility without comms..."
Aizawa didn't finish the sentence. He didn't have to. The memory of the Shie Hassaikai raid, of the war, of every time he had failed to protect his students, flashed through his mind.
Rei Arata did not panic. He closed his eyes, tapping deeply into the Omni-Weave.
He couldn't use the standard comms, but the Omni-Weave was not a radio signal. It was a conceptual tether linked to the souls of his Vanguard. He pushed past the electromagnetic interference, searching for the specific, golden-yellow resonance of Eri's Rewind, even if it was dormant.
"I have her," Nocturne declared, his dual-toned voice echoing with absolute authority. "She is subterranean. Approximately three hundred feet below the surface. The spatial distortion around the facility is too dense for Rin to open a portal directly inside without risking a catastrophic collapse of the cave system."
"Then drop me as close as you can," Aizawa demanded, turning toward the deployment bay.
"You aren't going alone, Eraser."
Mirio Togata—Lemillion—stepped into the command hub. He was fully suited in his Swarm-modified tactical gear. His blue eyes burned with the same intense, unyielding protective instinct that Aizawa felt. Mirio had lost his Quirk to save Eri once. He would not let her fall into the dark again.
"I can phase through the bedrock," Mirio stated, walking up to the war table. "If the facility is buried, I am the fastest drill we have."
Nocturne nodded. He raised his hand, channeling Rin's spatial algorithms.
"GateL0ck. Open a pinhole in the canopy directly above their coordinates," Nocturne commanded. He looked at Aizawa and Mirio. "Bring the children home. That is an absolute directive."
A silvery-blue tear in reality ripped open in the center of the Spire.
Aizawa and Mirio didn't hesitate. They dove through the portal, leaving the starlit heaven of Aegis Prime and plummeting directly into the freezing, rain-soaked night of the Oku-Hida mountains.
The Subterranean Laboratory.
"Left! Take the left corridor!" Katsuma screamed, looking at the holographic layout he had managed to pull from a shattered map terminal on the wall as they ran.
Class Zero sprinted down the rusted, echoing hallway. Behind them, the horrific, dragging footsteps of the Prototype Nomu grew louder. The beast was not as fast as a High-End, but its endurance was infinite, and it was tearing through the heavy steel doors in its path like wet tissue paper.
"It's gaining on us!" Kota yelled, glancing over his shoulder. The darkness of the corridor was absolute, illuminated only by the faint red emergency lights spinning on the ceiling.
They rounded a sharp corner and skidded to a halt.
They had reached a dead end. A massive, reinforced security door blocked their path. The words PRIMARY CONTROL VAULT were stenciled in faded white paint across the steel. Beside the door was a heavy, mechanical lever and a digital access terminal.
"It's locked!" Kota panicked, pulling desperately on the heavy steel lever. It wouldn't budge.
"Let me in," Katsuma said, pushing past Kota.
Katsuma ripped the access panel off the digital terminal, exposing a chaotic mess of frayed wires and archaic circuitry. He didn't have an offensive Quirk, but he was brilliant. He pulled a specialized, Swarm-issued multi-tool from his belt and began frantically splicing the old-world wires into his datapad.
"I can bypass the encryption, but Ujiko's operating system is a mess!" Katsuma shouted, his fingers flying across the screen as sparks flew from the terminal. "I need sixty seconds!"
SKREEEEEECH!
The Prototype Nomu rounded the corner at the far end of the corridor. It saw them trapped against the vault door. Its three yellow eyes locked onto Eri, and its jaw unhinged, acidic saliva dripping onto the grated floor. It charged.
"You have thirty," Eri stated, her voice shockingly calm.
Eri stepped to the front of the group, placing herself directly between the charging monstrosity and her classmates.
"Eri, what are you doing?!" Kota yelled, stepping up beside her, raising his hands to generate another water cannon. "We can't fight it!"
"We don't have to fight it. We just have to stall it," Eri said.
She reached up to her forehead. She closed her eyes. For years, she had been taught to suppress her power, to fear it, and then to use it only to heal. But Izuku Midoriya had told her that her Quirk was her own. It was not a curse. It was a tool.
The horn on her head ignited. A blinding, intense yellow light flooded the dark corridor, washing over the rusted steel and illuminating the charging Nomu.
"Rewind: Localized Stasis Field!"
Eri thrust her hands forward. She didn't unleash a massive, uncontrolled wave of temporal energy. With absolute, surgical precision drilled into her by the Sovereign, she projected a focused beam of Rewind directly at the grated floor in front of the charging Nomu.
She wasn't rewinding the monster; she was rewinding the structural integrity of the floor itself, taking it back to a point before the rust, before the support beams, back to raw, unsmelted iron ore.
The steel grating beneath the Nomu's heavy, mismatched feet instantly lost its molecular cohesion. The floor violently gave way.
The Prototype Nomu shrieked in confusion as the ground vanished beneath it. It plummeted into the sub-level maintenance shaft below the corridor with a heavy, metallic crash.
"Whoa," Kota breathed, staring at the massive hole in the floor.
"It won't hold it for long," Eri panted, dropping to one knee as the golden light faded. The sheer concentration required to execute a non-biological, localized rewind was physically exhausting. "It has hyper-regeneration. It will climb out."
"Got it!" Katsuma screamed triumphantly.
The heavy locking mechanisms of the vault door clicked, and the massive steel portal hissed open.
Class Zero scrambled inside the control vault. Kota grabbed the heavy mechanical lever on the inside and pulled it down with all his might. The vault door slammed shut behind them, the locks engaging with a satisfying, heavy thud.
They collapsed onto the floor of the vault, gasping for air in the dark.
Kota raised a small water sphere to illuminate the room.
The control vault was a sprawling, circular chamber. The walls were lined with massive, silent server racks and deactivated monitors. In the center of the room sat a large, primary control console.
But as the light from Kota's sphere reached the far side of the vault, the three teenagers froze.
The vault was not a dead end. It was an observation deck.
A massive wall of reinforced glass separated the control room from a cavernous, subterranean hangar beyond it.
Katsuma slowly walked up to the glass, his eyes wide with absolute, paralyzing horror.
Inside the cavernous hangar, illuminated by faint, sickly green bio-luminescent lights, were hundreds of towering, cylindrical glass vats.
They weren't empty.
Suspended inside the vats, floating in preservative fluid, was an entire army of dormant Prototype Nomus. Hundreds of twisted, bio-engineered monstrosities, waiting in the dark for a master who was already dead.
And on the primary control console in the center of the room, a large red button was blinking. The automated sequence had been initiated by whoever had restored power to the facility.
The digital countdown timer on the screen read: 00:03:00 UNTIL MASS THAW.
"Oh my god," Eri whispered, staring at the army of nightmares. "The copycat killer didn't just come to the mountains to hunt. He came to unleash an apocalypse on the settlement."
If those blast doors opened, Hope's Ridge wouldn't just be attacked; it would be completely, utterly erased from the map.
"Katsuma," Eri said, her voice dropping the panic, replacing it with the hardened resolve of the Vanguard. "Can you splice the comms from that terminal? Can you reach the Spire?"
"I... I think so," Katsuma stammered, running to the console and plugging his datapad into the primary interface. "The electromagnetic shielding in this vault is massive, but if I can route the signal through the facility's main antenna on the surface..."
BAM!
The heavy steel vault door behind them shuddered violently.
A massive, bone-white talon pierced straight through the center of the thick titanium door. The Prototype Nomu had climbed out of the pit. It was tearing its way into the vault.
"It's breaking through!" Kota yelled, his hands trembling as he raised them toward the door.
"Katsuma, get that signal out!" Eri commanded, turning her back on the nightmare and focusing entirely on her .
"Katsuma, get that signal out!" Eri commanded, turning her back on the nightmare and focusing entirely on her classmate. "Kota, hold the door! I'll back you up!"
The countdown timer on the console ticked down. Two minutes.
Hope's Ridge. The Surface.
The rain had turned the valley into a slick, bloody arena.
The Purge rolled out of the way as Stain's combat knife sliced through the space where his throat had been. The fanatic kicked outward, catching Stain in the ribs, forcing the Quirkless assassin backward into the mud.
"You are weak!" The Purge laughed, flipping his serrated blade. "You let the Sovereign take your fangs! You are a dog playing at being a wolf!"
"I am a man who woke up from a nightmare," Stain retorted, wiping the mud from his face. "You are just a child playing dress-up in a dead man's clothes."
Before The Purge could lunge again, a massive, localized earthquake shook the valley.
It wasn't a tectonic shift. It was a massive, concussive impact from the sky.
A figure slammed into the mud directly in the center of the settlement, creating a crater.
The Purge froze, looking at the crater.
Shota Aizawa stood up from the impact zone. His black tactical uniform was soaked, his capture scarf whipping violently around him like a swarm of angry serpents. His single visible eye was glowing with a terrifying, absolute crimson fury.
Aizawa didn't look at The Purge. He didn't look at the reformed villains.
"Where are my students?!" Aizawa roared, his voice carrying the sheer, unadulterated wrath of a father who had lost his patience.
The Purge let out a manic laugh. "Your students are dead, Eraserhead! They fell into the abyss! And in two minutes, the monsters waiting in the dark are going to wake up and tear this valley to shreds! The purge is absolute!"
Aizawa's eye locked onto the fanatic.
Erasure.
The Purge didn't have a flashy Quirk. He had a minor kinetic-enhancement ability that made him faster. The moment Aizawa's gaze hit him, that enhancement vanished. He suddenly felt incredibly heavy, slow, and human.
Before the copycat could even process the loss of his Quirk, a blur of golden-blue light shot out of the ground directly beneath his feet.
Mirio Togata phased upward, completely bypassing the mud.
"POWERRRR!" Mirio roared.
He delivered a devastating, picture-perfect uppercut directly to the underside of The Purge's masked jaw. The ballistic mask shattered instantly. The fanatic was launched fifteen feet into the air, his jaw completely broken, before crashing into the mud, unconscious before he even landed.
"The leader is down!" Nagant's voice echoed from the cliffs, accompanied by the rapid CRACK-CRACK of her sniper rifle efficiently disarming the remaining, panicked zealots.
Aizawa didn't celebrate. He turned to Mirio, his crimson eye wide with terror. "He said they fell. He said there are monsters."
Suddenly, the comms unit in Aizawa's ear, which had been dead static since he dropped, violently screeched to life.
It wasn't Rin. It wasn't the Sovereign.
It was a frantic, terrified, but unbroken voice slicing through the static.
"...Mr. Aizawa! Vanguard Command! This is Katsuma Shimano!" "Katsuma!" Aizawa yelled, pressing his hand to his earpiece. "Report! Are you injured? Where is Eri?!"
"We are trapped in a subterranean vault roughly three hundred feet below Sector 4!" Katsuma's voice rushed out in a frantic burst. "We found a dormant Nomu laboratory! There is an automated thaw sequence counting down! Hundreds of prototypes are going to wake up in sixty seconds! The door is failing! We can't hold it!"
In the background of the audio feed, Aizawa could hear the horrific, tearing sound of metal, followed by Kota roaring and the explosive sound of high-pressure water blasting against steel.
"Please, Mr. Aizawa!" Katsuma cried. "We need help!"
Aizawa looked at Mirio. He looked at the solid, muddy ground beneath their feet. Three hundred feet of solid bedrock separated them from the vault.
"Lemillion," Aizawa said, his voice dropping to a deadly, absolute calm.
Mirio nodded, his blue eyes hardening. "I can reach them, Sensei. But I can't carry three people back up through solid rock while holding my breath."
"You don't need to carry them," Aizawa stated, looking up at the dark, storm-choked sky. He tapped his comms, switching the frequency directly to the Omni-Weave emergency channel.
"Sovereign," Aizawa said. "We have the lock."
