The Chainsaw Man vs. KingRatMan part 1

The city was already dead when the sound began.

A low, choking RRRRRRRNNNNNN echoed through the alleyways, crawling up broken windows and cracked brick like a sickness. Streetlights flickered as if afraid to stay on. Somewhere in the dark, something was waking up.

The Chainsaw Man had returned.

He stepped out of the fog, boots crunching over bones and broken glass. His chainsaw arm dripped black oil and something darker that steamed when it hit the pavement. His breathing was wrong—too fast, too hungry—like the machine was breathing him.

Every rat in the city froze.

From the sewer grates, from abandoned buildings, from the subway tunnels below, thousands of red eyes opened at once.

They all looked toward the throne beneath the streets.

Deep underground, sitting on a pile of gnawed skulls and rusted metal, KingRatMan rose.

He was tall, hunched, wrapped in a torn cloak stitched together with human skin and sewer wire. His crown was made of broken traps and gold teeth. His face—half man, half rat—twitched as he sniffed the air.

“The Saw Beast is here,” he hissed.

The ground trembled as his army of rats answered the call—massive sewer rats, rat-men with blades, rats stitched together into crawling nightmares. The walls bled as they poured out, squealing, screaming, laughing.

KingRatMan lifted his clawed hand.

“Bring me his head.”

The first wave hit the Chainsaw Man like a living flood.

Rats swarmed his legs, biting, tearing, dragging him down. Rat-men leapt from rooftops, stabbing, shrieking praises to their king. The Chainsaw Man roared—half human, half engine—and revved his arm.

The night exploded into noise.

Steel teeth tore through fur and bone. Bodies flew. Screams cut short. But the rats didn’t stop. They never stopped. For every one that fell, ten more replaced it, crawling over the dead, biting into his wounds.

Chainsaw Man laughed.

A broken, distorted laugh.

He loved this.

Then the ground split open.

KingRatMan emerged from the sewer in a cloud of filth and smoke, towering over the carnage. His eyes burned yellow as he dragged a massive spiked mace made from a wrecked stop sign and human spines.

“You are loud,” KingRatMan growled. “But you bleed like the rest.”

He swung.

The blow sent Chainsaw Man crashing through a bus, metal screaming as it folded around him. Rats swarmed again, pinning him, gnawing at the chainsaw’s housing, clogging it with flesh and fur.

For a moment—just a moment—the chainsaw stalled.

The city went silent.

KingRatMan stepped closer, leaning down, breath hot and rotten.

“This city is mine.”

The Chainsaw Man’s head tilted.

The engine restarted.

RRRRRRRRRRRRRRRRR

He burst upward, shredding rats in a spiral of noise and madness, slamming into KingRatMan’s chest. The two monsters collided, claw against steel, fang against blade, rat screams mixing with machine howls.

Buildings shook. Fires ignited. Blood ran into the gutters like rain.

At dawn, the city was quiet again.

The streets were empty. No rats. No bodies.

Only deep claw marks, shredded concrete… and a single broken crown lying in the road.

From the shadows of a distant alley, the sound of a chainsaw faded away—slow, satisfied.

But deep underground, something scratched.

And laughed.
