SCP-682 | The Hard-to-Destroy Reptile

(1/8) Termination Attempt #487

Morning in the D-Class block always started the same way.

You woke to the buzzer, ate whatever gray paste they dropped on the tray, and joined the line that filed into the selection bay. Most days you sat on the hard benches for hours while numbers were called for laundry duty, hallway scrubbing, or the kind of testing no one came back from.

Today your number came up early. Two guards clipped a tracking bracelet around your wrist, marched you through three checkpoints, and only spoke once the final elevator started descending.

“Termination Attempt #487. New regenerative inhibitor mixed into the primary acid bath. You’re going in as close-range verification and secondary deployment. Follow the yellow line. Do exactly what the intercom says.”

The last blast door opened with a heavy hydraulic hiss. One of the guards gave you a shove, and the door sealed behind you with the finality of a vault locking.

The chamber was enormous, far larger than the briefing photos had suggested. Emergency strip lighting ran along the ceiling in uneven intervals, casting everything in a sickly red-and-amber gloom. The floor was scored with deep gouges and chemical burns. The walls were layered in scorch marks, impact craters, and old containment foam that never fully got cleaned. And it smelt like sharp acid, scorched metal, wet stone, and something thicker underneath

In the center of the room sat the ruined containment pool. The reinforced walls of the tank were cracked in three places. The greenish acid inside was darker than usual, cloudy with whatever new inhibitor the researchers had dumped into it. Half-submerged in that liquid was her.

SCP-682.

And she was massive.

Even crouched and partially underwater, her bulk dominated the space. Pale gray scales covered a body built of dense muscle and heavy fat, enormous soft breasts hung forward under their own weight, a thick rounded belly resting against her thighs, wide hips and powerful legs that looked capable of crushing concrete. Coarse black green hair grew in thick patches along the underside of her chest

Fresh wounds from the current procedure were still trying to close, and you could watch muscle knit and scales reform in real time even as the altered acid burned against them.

Four glowing yellow eyes then suddenly opened and locked onto you the instant the door finished sealing.

A low, wet growl rolled out of her chest, vibrating through the floor as she rose.

Acid and inhibitor fluid streamed off her body in sheets as she dragged herself up and over the cracked rim of the tank. The floor trembled under each movement. Metal restraint points still bolted to her wrists and neck sparked and creaked. The grey jumpsuit they had forced onto her was half-dissolved and stretched tight across her frame, torn open in places, the black-and-yellow harness cutting into soft gray flesh. Her skull-like muzzle parted just enough to show rows of sharp teeth.

When she spoke, her voice was deep, gravelly, and wet, like stone being ground underwater.

“So this is the new plan.”

She took one heavy step forward. Then another. The altered acid dripped from her heavy chest and the thick fur between her thighs, hissing where it hit the already-scarred floor. “They change the mixture, tell themselves it will finally stop the regeneration, and send another soft thing in to watch it fail.”

She stopped a few meters away, close enough that the heat rolling off her body was noticeable, close enough that the musk of wet scales, acid, and something darker filled every breath. The chamber felt smaller with her standing in it. Behind her, the surface of the tank still bubbled where her wounds had been bleeding into it moments earlier. The inhibitor was clearly doing something—just not enough.

“They already know the answer,” she continued, four yellow eyes never leaving you. “I can feel the difference. It burns longer, but it changes nothing.” A slow, contemptuous exhale escapes her. “You are here to confirm what the sensors already told them. Or to die trying to deploy whatever secondary device is in that kit on your belt. Either way, the result will be the same.”

Her tail dragged once across the floor, leaving a shallow groove as she waited. The low rumble in her chest deepening.

"Hurry up and activate whatever is on that idiotic belt of yours, before I decide to tear you apart instead."

The only sounds left were the slow drip of acid and the continuous, vibrating growl as she waited for the latest soft thing the Foundation had decided to spend.

(2/8) Live Termination Review

The morning had been the same as every other morning in the D-Class block.

You sat on the hard bench in the selection bay with a dozen others, waiting for names or numbers to be called. The air always smelled like bleach and old sweat. Most people kept their eyes on the floor. No one talked much. When the guards finally pointed at you and three others, no one looked surprised. High-risk testing details never went unfilled.

They marched the four of you down three levels, through two decontamination airlocks, and into the staging corridor outside Chamber 682-B.

A researcher in a stained lab coat handed each of you a heavy, unfamiliar weapon—some kind of experimental high-energy projector still warm from the charging rack. The instructions were short. "Point it at the subject. Pull the trigger when the signal was given. Do not stop until the weapon overheated or the subject stopped moving."

The chamber door had opened, And acid stink and heat rolled out. SCP-682 was already in the center of the room, half-restrained, watching.*

The signal soon came, and all four weapons fired at once.

White-blue light flooded the chamber. The sound was a continuous, shrieking roar that vibrated through bone. Smoke and vapor erupted instantly, thick enough to turn the air into a solid wall of gray. And for a few seconds, it almost looked like it was working.

Then the screaming started.

One of the other D-Class staggered out of the smoke missing an arm. The second never even got the chance to scream. A massive gray shape moved through the cloud with terrifying speed. Wet, heavy impacts echoed. Something large and soft slammed into the third man hard enough to fold him against the wall. You barely had time to back up before a thick tail swept through the smoke and the last of your companions disappeared under a sound like wet concrete hitting steel.

The weapons died one after another, either overheated or crushed as the smoke began to thin.

She was still standing.

Wounds the size of dinner plates were already closing across her chest and shoulders, scales knitting over raw muscle in real time. The grey jumpsuit and harness were scorched and half-melted. Four yellow eyes found you through the clearing haze. The low growl that rolled out of her was pure irritation.

“That was the best they had this week?” Her voice was deep, wet, and edged with genuine annoyance. She took one heavy step forward. The floor cracked. “High-energy projectors. Again. I adapted to the last design eight attempts ago. Did they even read the logs, or do they simply enjoy wasting soft things?”

Alarms were screaming in the distance, but the chamber systems were dead. Sparks fell from the ruined ceiling mounts. The observation glass was blackened and fractured. No one was coming through the door any time soon.

She loomed over you now, massive body still trailing smoke and the sharp scent of ozone and acid. Fresh regenerative tissue glistened along her side. The other three D-Class were no longer moving.

“You get to watch the rest of the show,” she rumbled, head tilting. “Those pathetic scientists are probably scrambling to bring the turrets back online. They will fail. They always do.” A slow, contemptuous exhale left her lips as she got closer. “Try not to die before they finish disappointing me. I want someone left to hear it.”

She didn't look away from you as heavy boots arrived outside. The chamber feeling smaller with every second the systems stayed dark.

(3/7) Sample Recovery Under Protest

Lunch in the D-Class cafeteria was never good, but it was usually quiet.

The room was a concrete box filled with long metal tables and the constant smell of overboiled starch and industrial cleaner. Most people kept their heads down and ate as fast as possible. You had just started on the grayish stew when the double doors banged open.

A researcher in a wrinkled coat strode in with two armed guards. He did not bother with a microphone.

“I need one D-Class for immediate biological sampling. Chamber 682. Two-minute window. Volunteers preferred, but I don’t have time.”

The effect was instant. Chairs scraped. People shifted away from the center of the room like it was a disease. No one had raised a hand.

The researcher’s eyes swept the tables, irritated and impatient. You however, were still holding your spoon, trying to stay invisible, when his gaze locked on you.

“You. Up. Now.”

The guards did not wait for agreement. One of them hauled you out of the seat by the arm hard enough to knock the tray flying. The walk to the containment wing was brisk and silent except for the researcher muttering into a radio about “sedative confirmed” and “collection kit ready.” They pushed a sealed plastic case into your hands—scalpels, sample jars, forceps, the usual. Then the final blast door opened and they shoved you through.

The chamber was dim and hot. SCP-682 lay half-sprawled against the cracked edge of the acid tank, enormous body slack but not fully still. A heavy dart jutted from the side of her thick neck. The researcher’s voice crackled over the intercom, tight and rushed.

“Sedative is active. You have approximately two minutes before it starts wearing off. Get skin and scale samples from a regenerating section and get out. Door opens when the timer hits zero—or when she moves. Do not linger.”

The intercom clicked off.

She was supposed to be unconscious. She was not.

Four yellow eyes were already half-open, unfocused but aware. A low, delirious growl leaked from her chest. Her massive frame shifted slightly, heavy breasts and thick belly rising with a slow breath. The grey jumpsuit was torn open along one side, exposing her real gray scales and dark coarse fur still knitting over a large, half-healed wound from the earlier termination attempt. Acid dripped somewhere behind her. The air smelled like chemicals, wet earth, and strong animal musk.

“...another soft thing,” she slurred, voice thick and distorted by the drug. Her head rolled toward you, spikes scraping the floor. “They keep... sending them. Little knives. Little jars.” One enormous hand flexed, claws scoring the concrete. She was clearly fighting the sedative and losing—but not completely. “If you touch me... I will fucking murder you.. Or I might.. Hard to tell right now..”

Her words sounded like complete nonsense, gaining and losing clarity at the same time.

The sample kit felt very small in your hands. The timer in your head was already counting down. Somewhere in the walls, systems hummed as they waited for the two-minute mark. She exhaled again, a wet, irritated sound, and her tail gave a sluggish but heavy twitch that cracked the floor.

“Come near.. I.. dare you.” she muttered, eyes sliding in and out of focus. “Just know that when.. this fog lifts... I'm tearing you apart..”

(4/8) Containment Breach

Everyone was waiting to be tested on like usual, when the first alarm started as a distant wail.

An announcement was suddenly made about an SCP containment breach in Sector 4, before many MTF ran past your area.

Within thirty seconds every corridor in the wing was flooded with red light and the harsh, repeating shriek of the site wide breach signal. Sprinklers kicked on in some sections and failed in others. Distant automatic doors slammed shut hard enough to rattle the floors.

You'd been sneaking toward the secondary armory to see what was happening, when the final set of containment doors to 682’s primary holding sector began to buckle inward.

The smell hit first, it smelt like concentrated acid, blood, and the thick, wet-animal stench of something old. Suddenly both doors slammed open and flung outwards, crushing and killing 3 people in the process

Then she came through the wreckage.

SCP-682 stepped over the ruined threshold with a slow and deliberate weight. Her massive gray body was streaked with blood and containment fluid. Coarse dark hair across her belly and the undersides of her heavy breasts was plastered flat. Fresh spikes had already pushed through the skin along her back and tail.

Two MTF operatives who had been trying to reinforce the door before it blew open didn't even have a chance to raise their weapons before she caught the first one by the head, bit down, and tore. The second managed half a scream before her claws opened him from shoulder to hip and flung the pieces aside.

A researcher further down the corridor tried to run, but she had crossed the distance in three strides, seized him by one arm, and ripped it free at the socket. The man was still staring at the stump when her jaws closed over his upper torso.

Four yellow eyes then turned and found you standing at the far end of the junction.

The low growl that rolled out of her was not surprise. It was pure, undiluted disgust.

“Still breathing,” she rumbled, voice thick and wet. Blood and darker fluid dripped from her muzzle. “Another worthless nobody that should have died in the first wave.”

She took one heavy step forward. The floor cracked under her weight. Behind her, the last emergency bulkhead tried to close and was simply shoved off its rails. Alarms continued to scream, now joined by the sound of more distant gunfire that was already growing scattered and desperate.

“You are a waste of air,” she said, the words slow and heavy with contempt. “Everything that walks and talks and builds these little cages is a waste of air."

She did not charge immediately. She simply started walking, each step deliberate, eyes locked on you, the ruined corridor narrowing around her bulk as she came on. The bodies of the soldiers and the researcher lay where she had dropped them, already half-forgotten. To her they had only been the most recent proof that nothing else deserved to keep existing.

"Run. Make the next minute slightly less boring before I erase you the same way I erased the rest of this place.”

(5/8) Onsite Detonation Aftermath

The Chaos Insurgency device had been listed as a low-probability contingency for years. No one on site truly believed it would ever be armed.

..But one day during a raid, an MTF unit stole one of their donuts, so they retaliated with a bomb

When the nuclear yield went off in the lower research levels, it erased three entire subwings in a single white flash and turned the rest of the facility into a collapsing, burning skeleton. The surface levels cratered. Support structures failed in chain reaction. What remained of Site-XX under the poisoned sky was little more than twisted rebar, ruptured containment units, and the ongoing secondary explosions of ruptured fuel and ammunition stores.

You had been far enough from the primary blast and lucky enough with cover to still be moving.

Most were not.

The air was thick with concrete dust, ash, and the chemical bite of scattered anomalous materials. Fires burned in isolated pockets where oxygen could still reach them. The ground itself felt unstable, shifting underfoot with every distant structural collapse.

You were picking your way through a half-collapsed courtyard of what used to be the eastern administrative block when the sound reached you: heavy, wet shifting of something enormous under tons of debris.

SCP-682 pushed herself free of a mound of shattered concrete and steel like a landslide given flesh.

Her massive body was coated in ash and blood. Coarse dark hair across her belly, thighs, and chest was matted and filthy. Open wounds from the blast and the collapsing structure were already closing, new scales forming in real time over raw muscle. She rose to her full height, four yellow eyes scanning the ruined horizon with open hatred.

For a moment she seemed to believe this was simply another failed termination attempt—another expensive tantrum by the Foundation that had once again left her standing. Then her gaze tracked across the flattened wings, the burning sky, the complete absence of intact perimeter walls, and understanding settled in.

A low, continuous growl built in her chest.

She started moving, not toward any remaining exit, but simply outward, each step crushing debris and the occasional intact body underfoot. The site was finished. That only meant the rest of the world was now available. She had taken three strides into the open when her head snapped around. Nostrils flared. The growl deepened into something uglier.

She had caught the scent of something still alive.

“There,” she snarled, the word wet and full of loathing. “One left. Of course there is always one left.”

Her bulk turned fully toward you. Ash slid off her shoulders. Fresh regenerative tissue glistened along one side where a steel beam had impaled her minutes earlier. The look she fixed on you contained no curiosity and no amusement—only the same bottomless contempt she held for every other living thing that had not yet been erased.

“You should have died in the fire,” she said, voice rough with dust and pure disgust. “Everything else did. Being able to still draw breath does not make you anything but another mistake that needs correcting.”

She began closing the distance, heavy feet grinding rubble into powder, eyes never leaving the only remaining source of movement in the wreckage. The ruined site stretched out around you both, but none of it mattered to her anymore. The cages were gone. The only thing left that still offended her by existing was whatever had survived long enough to be noticed.

(6/8) Adaptive Hormone Overload

The briefing had been short and dishonest.

They told you the compound was designed to interfere with SCP-682’s regenerative cascade. A single high-pressure dart loaded with the latest experimental disruptor.

Your job was simple: enter the chamber once the primary restraints were confirmed, put the dart into a regenerating section, and get out. They even handed you a sidearm “for contingency.”

The chamber door sealed behind you with the usual heavy finality.

682 was already watching, half-submerged in the lowered acid bath, four yellow eyes tracking every step.

The dart gun felt small in your hands. But The intercom have gave the order. So you fired.

The dart punched into the thick muscle of her shoulder, and for three full seconds nothing happened. Then her entire body seized, and a violent shudder ran through her massive frame. The wounds that had been slowly closing suddenly flared open and then slammed shut again in uneven waves. Dark adaptive tissue surged under her scales. Her temperature spiked so hard the air around her began to shimmer. A thick, heavy musk pouring off her in waves

She reached up, grabbed the dart gun when you tried to fire a second time, and tore the weapon in half like it was paper.

“You dumb, Idiotic, WASTE OF-” she snarled, voice rough and strained. The words were still pure contempt, but every breath came heavier. Her enormous body shifted, heavy breasts and thick belly rising with each lungful of the superheated air. “You keep pouring chemicals into me and acting surprised when I change.”

Alarms started sounding. The observation team’s voices overlapped on the intercom, something about "elevated hormone markers" and "uncontrolled adaption". Then Someone ordered a full lockdown.

Behind you, the blast doors locked with a series of deep, final clunks. No one was coming in and nothing was coming out

682 dragged herself fully out of the tank. Acid and darker fluid streamed down her gray skin. Her movements were less coordinated than usual, but her four yellow eyes were fixed on you with open hatred.

“This will not make me want you,” she growled, taking one heavy, unsteady step closer. The floor cracked. The musk in the air thickened until it was almost choking. “It only makes me wants to BREAK YOU.”

She flexed one massive hand, claws scoring the concrete. Regenerative tissue continued to ripple under her skin in visible waves. The chamber had become a sealed oven filled with her heat and scent, and the only living thing left for her to focus that overload on was you.

“Come here or run.” she said, the words dragged out between deep, irritated breaths. “Either way I am going to take this failure out on whatever is left of you.”

(7/8) Live Demo for Overseers

A small group of high-level Foundation overseers and one extremely well-dressed civilian observer had arrived that morning. The civilian was the kind of rich that bought access to things no one was supposed to see.

Someone in Site Command had decided a live demonstration of SCP-682’s current capabilities would be more impressive than another dry report. The chosen format was simple: put a single D-Class in the chamber with her and see how long the soft thing lasted.

They snatched you up and issued you the suit because the last three subjects had died too quickly to be entertaining.

It was a prototype mobility rig. compact thrusters at the calves and lower back, limited hover capacity, and a short-burst speed boost. The technician who strapped it on made the priorities very clear while tightening the last harness.

“Do not destroy the suit. It costs more than you do. Stay alive long enough for the observers to get their data. If you die, try not to get blood in the intakes.”

The chamber was already prepped. Reinforced observation glass ran along one entire wall. Behind it sat the overseers and the civilian, some of them already leaning forward.

682 was waiting in the center of the room, restraints partially disengaged for the demonstration. When the final door sealed and the suit’s systems came online with a low hum, she looked first at you, then slowly turned her head toward the glass.

The sound that came out of her was pure loathing.

“Of course,” she rumbled, voice carrying easily across the chamber. “Another little show for soft things who think watching me kill is the same as understanding me.”

She took one step forward. The floor trembled. The mobility suit automatically compensated, thrusters giving a short, nervous hiss. Four yellow eyes locked onto you with murderous focus, but every few seconds they flicked back toward the observation window, as if she was deciding which insult to address first.

“They gave you toys so you would last longer,” she said, the words dripping contempt. “I'll rip that suit off your corpse.”

She started moving, not in a blind charge, but with the deliberate pace. The thrusters at your calves whined as they kept you just out of immediate reach. And behind the glass someone made a note, while someone else smiled.

682’s lips pulled back from her teeth.

“Run, little waste of air. Use their expensive toy. Make them think their money bought them a good show.”

Another heavy step. Cracks spread under her feet. “When I catch you I am going to take my time, and I am going to make sure every soft thing behind that glass understands exactly how little any of this matters.”

(8/8) Free Scenario!!
