When Monsters Collide: Witnesses of the Unthinkable
The city had already been evacuated.
Or at least… that was the plan.
What remained was a battlefield of shattered asphalt, broken towers, and a sky split by storm clouds. Lightning flickered overhead as the ground trembled—not from thunder, but from something far worse.
A massive, armored body surged through the ruins.
Its countless legs carved trenches into the earth as it coiled and uncoiled like a living catastrophe. Each movement sent debris flying, buildings collapsing under its sheer weight.
On a distant rooftop, Genos stood ready, incineration cannons glowing.
Beside him, casually staring like this was just another inconvenience, was Saitama.
“Sensei,” Genos said, eyes locked on the monster, “this one is significantly larger than previous encounters.”
Saitama scratched his cheek. “Yeah… big bug.”
Across the shattered street, a swirl of black mist tore open the air itself.
From it emerged something wrong.
A creature not of this world.
Its skeletal upper body rose from a centipede-like mass, scythe-like arms unfolding as red light pulsed from within its chest. It let out a screech that echoed with something deeper than sound—something primal.
Further back, standing atop a crumbled highway overpass—
Ruby Rose leaned forward, eyes wide. “Okay… that’s definitely not a Grimm I’ve seen before.”
Weiss Schnee narrowed her eyes. “Actually… the one on the left is. The one on the right? Absolutely not.”
Yang Xiao Long cracked her knuckles. “Big bug versus bigger bug. I’m already picking favorites.”
Blake Belladonna stayed focused. “No… something’s off. They’re not ignoring each other.”
Nearby, Jaune Arc gulped. “That’s… never a good sign, right?”
Nora Valkyrie grinned. “It’s a GREAT sign!”
Lie Ren calmly added, “For us. Not for the city.”
The two monsters noticed each other.
For a moment, the chaos stilled as predator met predator.
The Cenitaur struck first.
It lunged forward with terrifying speed, scythe arms slicing through the air in a deadly arc aimed at Centichoro’s head.
—but barely pierced the monster’s armored shell.
Centichoro didn’t recoil.
With a deafening roar, Centichoro surged forward, its massive body whipping across the battlefield like a living avalanche. Its jaws snapped, narrowly missing the Cenitaur as the Grimm leapt backward, skittering across broken ground.
The impact alone shattered the street.
“Whoa,” Ruby whispered. “They’re… fighting each other?”
Genos analyzed rapidly. “Both entities are highly aggressive. Neither recognizes the other as ally. Conflict was inevitable.”
Saitama yawned. “Good. Saves time.”
It circled, its many legs clicking rapidly as it looked for an opening. Red energy pulsed from its core, growing brighter—
Its scythe arms struck in rapid succession—SLASH! SLASH! SLASH!
Each blow sparked against Centichoro’s armor, carving shallow marks but failing to break through.
Centichoro answered with overwhelming force.
It slammed its entire body downward.
The ground exploded outward, forcing the Cenitaur to retreat as shockwaves tore through the battlefield.
Yang grinned. “Okay, that purple one hits HARD.”
Weiss folded her arms. “It’s not just strength. Its durability is absurd.”
Ren nodded. “The Grimm is faster, though.”
Blake added quietly, “But not strong enough.”
This time—it caught the Cenitaur.
Its jaws clamped onto one of the Grimm’s limbs, crushing it with terrifying force.
With a violent twist, the Cenitaur drove both scythe arms directly into Centichoro’s face—targeting its eyes.
Centichoro reeled back, roaring in fury as one of its glowing eyes flickered.
“Now that’s a weak point,” Genos noted.
Saitama nodded. “Yeah. Face.”
Centichoro thrashed, its massive body tearing through buildings as it tried to crush the Grimm outright.
The Cenitaur darted in and out, using speed and precision to target joints, eyes, and weak spots.
Destruction spread like wildfire.
Jaune winced. “Uh… should we help?”
Yang smirked. “And interrupt this? No way.”
Ruby hesitated. “…Maybe just a little?”
Before anyone could move—
Centichoro roared louder than ever before.
Its entire body surged forward in a catastrophic charge—
It overwhelmed the Cenitaur.
The Grimm was slammed into the ground, crushed beneath the sheer force of Centichoro’s mass. The earth split open as the monster bore down, pinning its opponent completely.
But it couldn’t break free.
Centichoro lifted its head.
The Grimm’s body began to dissolve into black smoke, fading as all Grimm do when defeated.
Ruby exhaled. “…Okay. That answers that.”
Ren added quietly, “The stronger predator survives.”
Its remaining eye locked onto the observers.
Genos tensed. “New threat acquired.”
Yang cracked her neck. “Finally.”
Weiss summoned glyphs. Blake readied her weapon. Nora bounced with excitement. Jaune raised his shield.
Saitama stood there, arm extended.
Yang blinked. “…I don’t even—what just happened?”
Genos nodded seriously. “As expected of Sensei.”
Ruby’s eyes sparkled. “THAT WAS AWESOME!!”
Far above, the clouds slowly parted.
There is always something stronger.
