“Compiled from partial telemetry, squad feeds, hostile helmet recordings, and recovered civilian surveillance footage.”

Approach and Initial Contact⌗

The squad entered the civic block along Route D-6 at 0714 local. A wide commercial street. Market stalls, cloth awnings, the smell of cooking oil still hanging in the air from whatever life had been here an hour ago. Buildings rose three and four stories on either side, windows dark, facades pocked with old damage.

At point, Chimera.

No camouflage. No suppression. She walked the center of the street in full view, matte-black and unhurried, the dorsal harness riding her back like a second spine. The squad followed forty meters behind, rifles up, scanning windows.

The civilians had already gone. Most fled at the sound of the convoy. The rest scattered at the sight of her — a woman dragging a child by the wrist, a man stumbling over his own cart, faces turned away as if not seeing her might make her less real. No one screamed. Screaming was for things you could understand.

Halfway down the block, her dermis flickered. A brief chromatophore pulse, her default black replaced by a wash of something pale and shifting. It happened fast enough that the squad missed it. The handler didn’t. His feed flagged it: involuntary camouflage activation. She had sensed something before any of them knew there was something to sense.

She didn’t break stride.

Detonation⌗

The IED had been buried beneath a drainage grate near the center of the block. Pressure-plate trigger, daisy-chained to a secondary fragmentation charge in a rusted dumpster twelve meters ahead. The kill zone was the street itself. The squad was meant to be standing in it.

They never got the chance.

Twin obscurant canisters fired from her collar rail, punching into the air with a pneumatic bark. The street vanished. Dense particulate fog, multispectral, IR-opaque, swallowed everything in a grey-white tide. Visibility dropped to zero in under a second.

The hostiles panicked. Someone triggered the IED early.

The blast was a flat, percussive thud, dulled by the smoke but still strong enough to shatter the nearest windows and kick a wave of debris across the street. Shrapnel peppered her left flank. Her dermis absorbed it. She didn’t flinch.

From the rooftops and upper floors, gunfire. Muzzle flashes strobed through the haze. AK-pattern rifles, six or seven of them, firing blind. Rounds cracked off concrete, pinged off the armored vehicles behind her, slapped against her hide and skidded away.

Her auditory implants dissected the noise in real time. Position, elevation, weapon type, rate of fire. Eleven shooters. Two on the first floor left, three on the second, two on the rooftop. Four more across the street on the opposing roof.

She processed this in the time it took the squad to hit the ground.

Left Building — Floors One and Two⌗

She moved.

A tentacle whipped forward, and with it a disk-shaped charge, spinning end over end. It sailed through a first-floor window and detonated on contact. The shrapnel load shredded everything inside: walls, furniture, men. The blast punched outward through the window frame in a plume of dust and pink mist.

Before the echo died, she launched. Tentacles coiled against the pavement and released, a horizontal leap that carried over a thousand kilograms of bioform through the smoke and into the gutted room. She hit the floor in a crouch, claws gouging tile. The two men inside were already dead. She stepped through what was left of them without looking down.

Her tentacles fanned outward, pressing against walls, floor, ceiling, reading the building through vibration. Above her: three men on the second floor. Heartbeats rapid. Breathing shallow. One was trying to reload.

She pulled a shaped charge from the dorsal harness and pressed it to the ceiling with one tentacle. The charge adhered. She dropped back.

The detonation punched upward through the floor in a focused column of force. One man was directly above it. He simply ceased to be, the shaped blast converting him into a red vapor and a wet stain across the far wall. The shockwave threw the other two sideways. One hit the wall and slumped. The other scrambled for his weapon.

Chimera came through the hole she’d made.

She rose from below like something born from the wreckage itself. Tentacles first, hooking the edges of the shattered floor, hauling her mass upward with a grinding shriek of rebar and concrete. The man against the wall never saw her. A tentacle lashed around his torso and pulled. Something tore. He stopped moving.

The last one had found his rifle. He turned to fire.

Her snout blade caught him under the jaw. The ossified ridge drove upward through soft tissue and bone, lifting him off the ground. She held him there for a moment, pinned and twitching, then flicked her head sideways. The body hit the wall with a sound like a sack of wet grain.

The second floor was clear in under four seconds.

Left Building — Rooftop⌗

The two men on the roof had heard everything. The explosions, the gunfire cutting short, the screams that ended too fast. They were backing toward the stairwell when the first body came.

It sailed over the roof edge and hit the concrete between them. One of their comrades from the floor below, thrown with enough force to crack the surface where he landed. Limbs bent the wrong way. Face unrecognizable.

They ran.

Chimera came over the parapet a second later, vaulting the lip of the building with her tentacles and landing in a low crouch. No sound except the crack of concrete under her weight.

The first man was three strides from the stairwell door. A tentacle caught his ankle. He went down hard, chin splitting on the rooftop, rifle skittering away. She dragged him back across the concrete, slow enough that he could scream, fast enough that he couldn’t grab anything. Then she picked him up and broke him against the roof edge like a man snapping kindling.

The second reached the door. His hands found the handle. He almost pulled it open.

A bladed tentacle punched through his back and out through his sternum, driven forward with the full weight of her lean behind it. He looked down at the tip protruding from his chest. His hands slipped off the handle. His mouth opened. No sound came out. She twisted once, wrenched the blade free, and let him drop into the stairwell, painting the steps behind him.

Right Building — The Hunt⌗

The four men on the opposing rooftop had watched the left building go silent. They’d seen the smoke, heard the detonations, watched the muzzle flashes cut out one by one. They’d called for their comrades. No answer.

They were already afraid.

Two objects arced out of the smoke below, spinning, heavy, trailing dark ribbons of gore. Bodies. Flung from the left rooftop across the fifteen-meter gap. One slammed into the rooftop at their feet, spraying bone and gristle across their boots. The other crashed through a window on the floor below, disappearing into the dark interior.

Before they could process it, she followed.

She came out of the haze at speed, tentacles extended behind her like the limbs of something aquatic, body coiled for impact. She had launched herself from the opposing roof, a ballistic arc across the street, and she hit the right rooftop like a mortar round. The man beneath her landing point didn’t scream. The impact simply erased him, a wet compression of bone and tissue spread across the concrete in a radial splash.

The remaining three fired. Point blank. Full auto. Rounds hammered her dermis and ricocheted, sparking off the harness, flattening against her hide, punching small divots that sealed shut almost as fast as they opened. She didn’t slow down.

One man she caught with a foreleg swipe, claws extended, thirty centimeters of ossified blade, that opened him from hip to shoulder. He spun and fell in two directions.

Another she seized with two tentacles, one around each arm, and pulled. The sound was terrible.

The last man dropped his rifle. He made it three steps before she was on him.

Right Building — Interior Clearance⌗

Below, the remaining hostiles had heard their rooftop collapse. The gunfire, brief and frantic, then nothing. The silence that followed.

They ran for the stairwell. All of them. Pushing, shoving, stumbling over each other in the narrow concrete passage. Rifles abandoned or clutched uselessly.

From somewhere in the walls, transmitted through rebar and concrete, a vibration. Deep. Rhythmic. The heavy cadence of something massive descending faster than the building should allow.

They reached the ground floor. The rear exit. A steel door opening onto a back alley.

The first man hit the push bar and the door swung open. Relief washed across his face for the half-second it took a tentacle to drop from above the door frame and seize him by the skull. He was wrenched upward. There was a crack, heavy, wet, final, and then blood sheeted down from the darkness above the lintel. His body followed a moment later, crumpling into the doorway.

The remaining two broke. One never made it back up the first flight. Something reached through the narrow stairwell window and took him. The crack of his spine against the opposite building’s wall echoed through the block.

The last man made it to the rooftop stairwell exit. He didn’t try the door. He pressed himself against the cracked side wall, rifle shaking in his hands, breathing in short, ragged pulls.

Silence.

Then the wall behind him bulged outward and a bladed tentacle tip punched through. It entered his lower back, drove upward through his abdomen, and emerged below his ribs. He looked down at it. His mouth worked, but there was only blood.

The tentacle twisted once and pulled him backward through the collapsing wall. The stairwell was left empty. Blood pooled on the landing below, already cooling.

Aftermath⌗

In the street, the squad hadn’t moved.

They’d watched fragments of it through the handler’s shared HUD feed, a shaking first-person nightmare of dark rooms and wet impacts and men coming apart in ways that would follow them into their sleep.

The smoke was thinning. Dust settled in slow curtains. Somewhere above, a length of rebar groaned and fell, clanging off a fire escape.

One of the soldiers took a step backward. Another ripped his helmet off and vomited against a market stall. A third had dropped his rifle at some point, he couldn’t remember when, and stood with his hands at his sides, fingers twitching.

The handler’s hand hovered over his comm unit. He’d forgotten why.

From the settling haze, she emerged.

Massive. Unhurried. The matte-black hide slicked with red in long streaks, drying to a dark crust along her flanks. The combat harness glistened. Her tentacles trailed behind her, loose and swaying, the bladed tips still wet. She moved through the rubble and the remains with the indifference of weather, stepping over a severed arm the way a person might step over a puddle.

She stopped in the street. The squad was fifteen meters away. None of them raised a weapon. None of them spoke.

Her voice, when it came, was low and rough. The coarse register. The one built for them:

“Threat neutralized.”

No one acknowledged.

She turned her head. A slow rotation, almost mechanical, the way a turret tracks. Her eyes swept across them, dark, flat, unreadable. Something in the lizard-back of every soldier’s brain screamed at them to run. Not from danger. From recognition. From the understanding that they were standing in front of something that could do to them what it had just done to eleven armed men, and the only thing between that possibility and this moment was the belief, trained into her since birth, that they were not enemies.

She held them in her gaze for three seconds.

Then she turned away and walked into the thinning smoke, her silhouette shrinking, her footsteps fading into the creak and settle of a ruined street.

No one followed.

Handler Post-Action Note (informal, not filed):
I’ve watched it back three times. I keep looking for the moment it stops being tactics and starts being something else. I can’t find it. Every movement is efficient. Every kill is purposeful. There’s no cruelty in it. No hesitation. No excess. That’s what scares me. She didn’t enjoy it. She didn’t hate it. She just did it. The way you’d clear a room of furniture. The way you’d pull weeds.

Forty-seven seconds. Eleven men. And she walked out of it like she was leaving a building she had no reason to remember.

I don’t know what that makes her. I don’t think I want to.
