+ FOUNDER RECORD — SCP-9476
Codename: //“The Twisted Maw”//
Author: {{[REDACTED]}}
Status: CLASSIFIED
Location of Initial Discovery: Abandoned industrial drainage complex, Northern England
Date of Discovery: {{██/██/20██}}
---
I was the first person to survive a direct encounter with what is now designated SCP-9476.
At the time, I did not know what it was.
Nobody did.
The disappearances began quietly. Twelve people vanished over roughly six weeks near an abandoned industrial estate outside {{███████}}. Most had entered the old drainage tunnels beneath the site.
Some were urban explorers.
Some were local workers.
Others were teenagers daring one another to enter the tunnels after dark.
The first reports sounded ridiculous.
Residents claimed they heard voices coming from storm drains. The voices whispered names. Sometimes they sounded like relatives. Sometimes they sounded like missing people.
One witness claimed that a voice beneath the pavement perfectly imitated his own.
Local police believed somebody was hiding underground and deliberately frightening people. Eight officers entered the drainage system to search for the missing civilians.
Only one came back.
He was discovered nearly three kilometres from the entrance, covered in injuries and unable to speak. He repeatedly drew the same symbol:
//A tall triangular head with a horizontal opening across its lower half.//
That was when the Foundation became involved.
---
+ ENTRY RECORD
I joined the first investigative team sent into the site after local authorities were removed.
We entered shortly after {{02:00}}.
The tunnels were colder than they should have been. Water covered sections of the floor, but we could not hear our footsteps echo properly.
The sound seemed to disappear several metres ahead of us.
The deeper we travelled, the more evidence we found.
* Clothing.
* Broken flashlights.
* Police equipment.
* Sections of wall covered in a dark, wet biological residue.
Some of the material contracted when exposed to the heat from our lights.
We eventually reached an underground chamber that did not appear on any available drainage plans. The chamber was much larger than the surrounding tunnels and had been formed partly from concrete and partly from something organic.
SCP-9476 was standing in the centre.
It was facing away from us.
Its body was approximately three and a half metres tall, although it remained hunched forward. Its shoulders were broad and heavily developed. Its arms extended almost to the ground, and thick tendon-like structures wrapped around its limbs and torso.
The entire body was dark blue-black and reflected our lights like wet stone.
Its head was shaped like an elongated wedge.
At first, I believed its surface was covered in holes.
When I looked closer, I realised that every black dot was an eye.
There were too many to count.
Thousands were visible from where I stood, but the surface appeared to contain far more. Each eye moved independently.
Some focused on the walls.
Some watched the floor.
Others rotated backwards toward us despite the creature never moving its head.
Every eye stopped at the same moment.
They all focused on our team.
SCP-9476 remained motionless for approximately forty seconds.
Then it spoke.
It used the voice of the missing police sergeant.
«“There are only seven of you now.”»
There were eight members in our formation.
I turned toward the rear of the team.
The last member had disappeared.
There had been no scream, impact, or visible movement.
He had simply been removed from the formation.
---
+ INITIAL ATTACK
The creature’s mouth opened.
What I had believed to be a line beneath its head unfolded into several thick layers of tissue. The opening expanded through its neck and upper torso.
There were no normal teeth inside.
Instead, hundreds of flexible cartilage structures moved independently, gripping and folding inward.
Saliva-like fluid stretched between the layers.
The sound it produced was not a roar.
//It sounded like multiple people attempting to breathe through the same throat.//
SCP-9476 crossed the chamber before any camera captured it moving.
The first officer it reached was killed in less than thirty seconds. The external tendons around its arm unwound, restrained him, and pulled him toward the mouth.
Ballistic fire damaged the entity, but every wound began sealing almost immediately.
The same ammunition became less effective after repeated impacts.
Its tissue hardened around the damaged areas.
We attempted to retreat through the tunnel, but SCP-9476 did not pursue us directly.
It moved through cracks in the walls and reappeared ahead of us.
At one point, half of its body compressed through a drainage opening far too small to contain it.
The entity did not move like an animal.
It moved like something changing its shape to match the space around it.
During the escape, it began imitating our radio transmissions.
It repeated orders using the voices of our team leader and command personnel. Some instructions directed us toward blocked tunnels.
Others told us to separate.
It understood what panic would make us do.
I reached the surface with two surviving members.
Containment required four separate response teams, cryogenic equipment, ultraviolet suppression systems, and the controlled collapse of multiple tunnel sections.
SCP-9476 was eventually immobilised after its temperature was reduced below freezing.
It did not die.
Its body entered a hardened dormant state and resumed movement once it began warming during transport.
The first sound it produced after waking was an exact imitation of the transport vehicle’s electronic lock.

+ ABILITIES OBSERVED
++ Physical Strength
SCP-9476 possesses extreme physical strength. It can deform reinforced metal doors, fracture concrete walls, and overpower multiple armed personnel within seconds.
++ Movement Speed
The entity is capable of reaching speeds exceeding {{78 km/h}} in enclosed corridors.
Its true maximum speed remains unknown.
It can alternate between upright and quadrupedal movement. The external tendons wrapped around its limbs tighten during acceleration and appear to function as additional muscles or biological springs.
SCP-9476 can jump several metres vertically and more than twelve metres horizontally.
Its fingers and feet can grip small cracks in concrete, metal, and reinforced surfaces, allowing it to climb walls and ceilings.
++ External Tendons
The tendon structures surrounding its body are independent muscular organs. They can unwind and extend several metres from the entity.
These tendons can:
* restrain living targets;
* pull objects toward the entity;
* enter ventilation shafts and electrical conduits;
* detect heat and pulse vibrations;
* anchor SCP-9476 to walls or floors;
* manipulate doors and machinery;
* and continue moving after being severed.
Detached tissue remains alive for several hours. Small samples move toward sources of heat, absorb nearby organic material, and attempt to reconnect with the main body.
++ Regeneration and Adaptation
SCP-9476 possesses rapid regeneration.
Minor injuries heal within seconds.
Severed fingers regenerate within minutes.
Entire limbs can regrow over several hours.
Its regeneration is adaptive rather than purely restorative. Each time the entity is injured, the replacement tissue becomes more resistant to whatever caused the damage.
* After gunfire, its skin thickens.
* After fire, it develops heat-resistant layers.
* After electrical exposure, insulating tissue forms around damaged areas.
* After crushing injuries, its joints and supporting tissue become denser.
Repeated use of the same weapon becomes progressively less effective.
++ Dimensional Compression
The entity can alter its body dimensions.
It can flatten sections of its torso, compress its joints, and pass through gaps far smaller than its normal frame.
++ Ocular System
Its wedge-shaped head is covered in countless black eyes, providing near-complete visual coverage.
Each eye moves independently.
SCP-9476 can track multiple targets simultaneously and observe movement in almost every direction without turning its head.
When threatened, all visible eyes focus on a single target at once.
Destroying the eyes does not permanently blind the entity. Damaged eyes regenerate rapidly, and additional eyes may form around the injured region.
++ The Maw
The mouth of SCP-9476 can expand to several times the width of its head.
The opening is not limited to the skull. During feeding or attack, the mouth may unfold through the neck, chest, and upper abdomen.
Its interior contains flexible gripping structures capable of cutting, crushing, and pulling material inward.
Internal scans suggest that the mouth may not lead to a conventional digestive system.
One cavity inside the entity appeared larger than SCP-9476’s external body. A probe inserted into this cavity travelled several metres before communication was lost.
It is possible that the mouth functions as an entrance to an extradimensional internal space.
++ Biological Assimilation
SCP-9476 does not appear to require food for survival, but it consumes biological tissue to adapt.
After feeding, the entity can temporarily reproduce physical characteristics from consumed organisms.
Observed changes include:
* increased muscle density;
* additional fingers;
* altered joints;
* new surface tissue;
* changes in body temperature;
* and the development of vocal structures.
Human biological material causes the strongest transformations.
++ Vocal Mimicry
After exposure to human blood, SCP-9476 gained the ability to reproduce speech.
It can imitate voices, crying, laughter, coughing, emergency alarms, radio interference, security announcements, and electronic access sounds.
The mimicry becomes more accurate with repeated exposure.
SCP-9476 has used familiar voices to lure personnel into unsafe areas.
It has also reproduced the voices of deceased Foundation staff members whom it is not known to have encountered.
++ Intelligence
The entity is highly intelligent.
It studies:
* feeding schedules;
* guard rotations;
* alarm systems;
* door mechanisms;
* maintenance periods;
* containment procedures;
* and individual personnel behaviour.
It performs small tests against containment systems and rarely repeats a failed escape method.
SCP-9476 is patient enough to remain motionless for several days while continuing to monitor activity outside its chamber.
It appears to understand fear and uses it as a weapon.
It does not always attack the strongest target first.
It separates groups, manipulates communication, imitates trusted voices, and waits for victims to make predictable decisions.
---
+ KNOWN WEAKNESSES
Weaknesses remain limited.
Low temperatures significantly reduce its movement speed and regenerative ability.
Cryogenic exposure can force the entity into temporary dormancy.
Ultraviolet radiation damages its outer tissue, although SCP-9476 eventually develops partial resistance.
Sustained electrical discharge can interrupt movement briefly but becomes less effective after repeated use.
--No method has permanently killed SCP-9476.--
No successful termination method currently exists.
---
+ FINAL PERSONAL STATEMENT
I do not believe SCP-9476 is simply an animal.
It watches too carefully.
It changes too deliberately.
It does not consume living organisms because it is hungry.
It consumes them because each body teaches it something new.
«A muscle teaches it strength.»
«A voice teaches it deception.»
«An injury teaches it resistance.»
«A frightened person teaches it exactly how humans behave when they believe they are about to die.»
The creature we found beneath the industrial estate may not have been its original form.
SCP-9476 may not possess an original form at all.
It may be constructing itself from everything it encounters.
Every person it kills gives it another movement, sound, structure, memory, or behaviour to reproduce.
The Foundation believes SCP-9476 is contained.
I believe containment is simply the latest environment it is studying.
The last time I observed the entity, it stood beside the inner chamber door during a security rotation.
It placed one hand against the metal.
Before the approaching guard spoke, SCP-9476 used the guard’s own voice and said:
«“You can stop watching now. I know how to be you.”»+ SCP-9476 — “The Twisted Maw"

Object Class: Keter
Threat Level: Red
Secondary Classification: //Predatory Biological Anomaly//
Containment Site: Site-19, Subterranean Biocontainment Sector 7
---
+ Special Containment Procedures
SCP-9476 is contained within a reinforced humanoid biocontainment chamber measuring {{18 m × 18 m × 14 m}}.
The chamber must be constructed from:
* layered tungsten-alloy plating;
* high-density concrete;
* shock-absorbing polymer;
* and an internal sacrificial wall capable of being replaced following structural damage.
The chamber must remain between 4°C and 7°C.
Temperatures above 13°C have been observed to increase SCP-9476’s:
* movement speed;
* tissue flexibility;
* aggression;
* and regenerative ability.
Humidity must remain below 20%.
The chamber floor is fitted with:
* vibration detectors;
* thermal sensors;
* pressure plates;
* chemical dispersal vents;
* concealed restraint anchors;
* and six independently controlled high-intensity ultraviolet lighting arrays.
No conventional glass observation windows are permitted.
Surveillance must be conducted through shielded thermal cameras, low-light cameras, acoustic sensors, and short-range radar.
Cameras must be mounted behind replaceable protective shutters due to SCP-9476’s repeated attempts to destroy objects resembling eyes.
The primary chamber door consists of three independent containment barriers.
No two barriers may be opened simultaneously.
Personnel entering the containment sector must wear sealed protective equipment.
No person is permitted to enter SCP-9476’s chamber while the entity is active.
Feeding is conducted remotely once every seven days.
SCP-9476 is to receive no more than {{35 kg}} of animal tissue during a single feeding cycle.
Human tissue is strictly prohibited following Incident 9476-04.
Any vocalisations produced by SCP-9476 must be recorded remotely.
Personnel are forbidden from answering, imitating, or verbally acknowledging these sounds.
If SCP-9476 begins repeating the name of a staff member, that individual must immediately leave the containment sector and undergo psychological evaluation.
The affected individual may not return within {{500 m}} of SCP-9476 for a minimum of thirty days.
In the event of a containment breach, all personnel must avoid:
* narrow corridors;
* ventilation shafts;
* dark rooms;
* and areas containing exposed organic material.
SCP-9476 can alter its body dimensions to pass through spaces significantly smaller than its resting frame.
Approved temporary suppression methods include:
* ultraviolet saturation;
* cryogenic foam;
* and sustained electrical discharge.
--Lethal force is expected to terminate SCP-9476.--
Lethal force is not expected to permanently terminate SCP-9476.
---
+ Description
SCP-9476 is a tall humanoid organism composed of dense blue-black biological material resembling a combination of muscle tissue, cartilage, scar tissue, and malleable industrial polymer.
When standing fully upright, SCP-9476 measures approximately 3.4 metres in height, although its apparent height varies according to posture.
The entity normally maintains a forward-hunched stance, causing it to appear shorter until threatened or actively hunting.
Its body is disproportionately constructed.
The shoulders are broad and heavily developed, while the waist narrows sharply before widening into a dense pelvic structure.
Its arms are unusually long, extending below the knees even when partially bent.
One arm is consistently observed to be between {{8 cm and 16 cm}} longer than the other, although the longer side appears to change following periods of regeneration.
The legs are thick near the upper body but narrow progressively toward the ankles.
The feet possess several flexible, claw-like digits capable of:
* gripping metal flooring;
* climbing vertical surfaces;
* and anchoring the entity during sudden movement.
Despite its size, SCP-9476 produces very little sound while walking.
The entity’s skin is predominantly deep slate-blue, with patches of violet-grey, black, and faint teal pigmentation.
Pale ash-coloured markings appear around damaged tissue and frequently develop into scar-like ridges.
The outer tissue is cold, moist, and slightly reflective.
Microscopic examination of recovered samples reveals no recognisable cellular structure.
The material appears to reorganise continuously, forming temporary cell-like compartments only when exposed to injury, heat, or chemical agents.
Detached tissue remains active for several hours.
Small samples have demonstrated:
* rhythmic contraction;
* limited movement toward heat sources;
* absorption of nearby organic material;
* and attempts to reconnect with larger tissue masses.
All detached samples must be incinerated following testing.
---
+ Cranial and Ocular Structure
SCP-9476’s head is its most distinctive anatomical feature.
The upper portion forms a thick, elongated wedge or cone that tapers toward a rounded point.
The shape resembles a heavily folded hood formed from biological material, although no separate skin layer exists.
The entire cranial surface is covered in countless small black ocular organs.
From a distance, these organs resemble holes or pores.
At close range, each can be observed blinking, contracting, rotating, and focusing independently.
No reliable estimate of their total number has been established.
The eyes provide SCP-9476 with near-complete visual coverage.
It can monitor multiple directions simultaneously without rotating its head.
When SCP-9476 becomes threatened or prepares to attack, every visible eye may focus upon a single target.
Destroyed ocular organs regenerate within seconds or minutes.
In several cases, additional eyes developed around previously damaged tissue.
The head can rotate approximately {{160°}} without corresponding movement from the shoulders.
In addition to sight, SCP-9476 detects its environment through:
* vibration;
* temperature;
* electrical activity;
* sound;
* and an unidentified mechanism capable of locating living organisms through reinforced walls.
Testing suggests that SCP-9476 can distinguish individual humans by heartbeat pattern.
It has identified personnel encountered previously even while those individuals wore sealed armour or approached from behind solid barriers.
---
+ The Maw
The lower-front section of the head contains a horizontal mouth concealed between overlapping layers of tissue.
When closed, the mouth resembles a thick fold or seam.
When opened, it expands into a large irregular cavity extending deep into the upper torso.
The mouth contains no conventional teeth.
Instead, its interior is lined with hundreds of flexible cartilage structures.
These structures remain blunt while inactive but become pointed when pressure is applied.
They are capable of:
* gripping;
* cutting;
* crushing;
* and pulling material inward.
The mouth can open to nearly four times the width of the entity’s head.
This expansion occurs through internal tissue unfolding rather than conventional jaw dislocation.
During feeding, the front of the head separates into several layered sections, creating the appearance of a flower, wound, or opening shell.
The jaw does not move vertically in a conventional manner.
Its folds rotate, separate, and contract independently.
The mouth produces a low internal vibration that can be felt through nearby walls.
This feature led to the designation:
«“The Twisted Maw.”»
---
+ External Tendon Structures
SCP-9476 possesses several rope-like biological structures wrapped around its arms, legs, shoulders, and torso.
These structures were initially believed to be exposed tendons.
Examination has shown that they are independent muscular organs connected to the entity at multiple points.
They move separately from the limbs beneath them.
The structures tighten whenever SCP-9476:
* runs;
* jumps;
* climbs;
* or attacks.
They appear to function as external muscle fibres, allowing SCP-9476 to produce force beyond the expected limits of its apparent skeletal frame.
When threatened, the tendons become rigid and form natural armour around vulnerable areas.
They can also unwind from the body.
Fully extended, individual strands have reached lengths exceeding six metres.
SCP-9476 uses them to:
* restrain prey;
* pull objects toward itself;
* anchor its body;
* block doors;
* detect movement;
* protect damaged limbs;
* and manipulate objects beyond the reach of its hands.
During Incident 9476-02, one strand entered a ventilation opening less than four centimetres wide and travelled approximately eleven metres before attacking a technician in an adjacent control room.
The strands appear capable of detecting body heat and pulse vibrations.
Severed tendons continue moving independently and attempt to return to SCP-9476.
---
+ Behaviour
SCP-9476 is intelligent, patient, and highly observant.
It does not display constant aggression.
For extended periods, the entity may remain motionless in a corner of its chamber, often facing a wall or standing directly beneath a surveillance camera.
These periods of inactivity can last between several minutes and seventeen days.
During these periods, SCP-9476 continues monitoring its environment.
Repeated testing confirms that the entity remains aware of personnel movement outside its chamber even when no visible reaction occurs.
It appears to study routines.
SCP-9476 has demonstrated the ability to recognise:
* feeding schedules;
* security rotations;
* maintenance periods;
* door mechanisms;
* alarm patterns;
* containment procedures;
* and individual staff behaviour.
It frequently tests containment systems using minor movements designed to appear accidental.
Observed examples include:
* leaning against walls;
* touching camera mounts;
* blocking drainage grates;
* applying pressure to door seams;
* and allowing tissue fragments to enter mechanical components.
SCP-9476 rarely repeats a failed escape method.
The entity becomes active most often between {{02:00 and 04:00}}, regardless of changes to Site-19’s lighting schedule.
While hunting, SCP-9476 lowers its body toward the floor, often placing one hand against the ground while keeping the other extended.
Its eyes independently track nearby movement before collectively focusing upon its selected target.
Its initial movement appears slow and cautious.
Once prey attempts to escape, SCP-9476 accelerates rapidly.
Its highest confirmed speed in a straight corridor is 78 km/h.
Researchers do not believe this represents its maximum speed.
SCP-9476 can alternate between bipedal and quadrupedal movement.
When moving on all four limbs, its external tendons tighten around the joints and function similarly to springs.
The entity can jump at least:
* twelve metres horizontally;
* and nine metres vertically.
It can climb concrete, metal, and reinforced glass by forcing its digits into microscopic cracks and surface imperfections.
---
+ Feeding Behaviour
SCP-9476 consumes biological tissue but does not appear to require food for survival.
It has remained active for more than eight months without feeding.
When presented with animal tissue, SCP-9476 initially touches the material using one or more external tendons.
The tissue is then drawn toward the mouth and compressed.
Large pieces are folded, crushed, and gradually absorbed.
The entity does not digest matter through a conventional digestive system.
Internal scans indicate that consumed material is distributed throughout its body.
Bone, skin, blood, muscle, and organs are separated and incorporated into different anatomical regions.
After feeding, SCP-9476 may temporarily display characteristics associated with the consumed organism.
Observed effects include:
* increased muscle density;
* additional digits;
* temporary fur-like fibres;
* altered joint structure;
* new vocalisations;
* and changes in body temperature.
These adaptations usually disappear after several days.
Human tissue produces significantly stronger effects.
Following accidental exposure to human blood, SCP-9476 developed vocal structures and began imitating speech.
---
+ Vocalisation and Mimicry
SCP-9476 was initially believed to be incapable of producing sound beyond breathing-like vibrations and low-frequency resonance.
This assessment changed following Incident 9476-04.
The entity can reproduce human voices by reshaping tissue inside its mouth and upper chest.
It does not possess conventional vocal cords.
Its mimicry is imperfect initially but improves rapidly after repeated exposure.
SCP-9476 has imitated:
* crying;
* coughing;
* whispered conversation;
* security announcements;
* radio interference;
* laughter;
* emergency alarms;
* electronic locks;
* and individual staff members.
The entity often combines unrelated phrases it has overheard.
Documented examples include:
«“Open the second door.”
“I am still outside.”
“The camera cannot see me.”
“You forgot someone.”
“That is not my mouth.”
“Do not turn the light on.”»
SCP-9476 appears to understand the emotional effect of its speech.
It has used the voices of injured personnel to attract security teams.
It has also imitated children despite no children ever having been present within its containment sector.
In several recordings, voices produced by SCP-9476 were identified as belonging to deceased Site-19 personnel who died years before the entity’s discovery.
No evidence confirms that SCP-9476 encountered these individuals.
---
+ Regeneration
SCP-9476 possesses extreme regenerative ability.
Small injuries heal within seconds.
Severed digits regrow within minutes.
Lost limbs regenerate over a period of two to seven hours depending upon:
* available biological material;
* ambient temperature;
* and the nature of the injury.
The entity’s regeneration is not merely restorative.
It modifies its body in response to the cause of damage.
Documented adaptations include:
* thicker tissue after ballistic damage;
* heat-resistant surface layers after exposure to fire;
* insulating growths after electrical attack;
* reinforced joints following crushing injuries;
* and reduced fluid loss following laceration.
Repeated use of the same weapon becomes less effective.
SCP-9476 appears to retain a biological memory of previous injuries.
Following ultraviolet exposure, the entity developed dark reflective patches that reduced tissue penetration.
Researchers were subsequently required to vary ultraviolet wavelengths during suppression attempts.
Cryogenic temperatures remain the most reliable method of slowing regeneration.
Prolonged exposure causes SCP-9476 to enter a hardened dormant state rather than die.
Once warmed, the entity resumes activity.
No permanent termination method has been identified.
---
+ Discovery
SCP-9476 was discovered beneath an abandoned industrial estate near {{███████}}, Northern England.
Local authorities began investigating after twelve people disappeared over a six-week period.
Most missing individuals had entered a sealed drainage network beneath the property.
Witnesses reported hearing voices coming from storm drains at night.
The voices allegedly called people by name.
Police initially believed the disappearances were connected to an offender living inside the tunnels.
A search team consisting of eight officers entered the drainage system.
Only one returned.
The surviving officer was discovered approximately three kilometres from the entrance, severely injured and unable to speak.
He repeatedly drew a triangular figure with a horizontal line across its face.
Foundation personnel intercepted local emergency communications and assumed control of the investigation.
Mobile Task Force Eta-11 entered the tunnel network two days later.
The team located a large underground chamber filled with:
* organic residue;
* discarded clothing;
* damaged equipment;
* and human remains.
SCP-9476 was found standing in the centre of the chamber.
It did not attack immediately.
Body-camera footage shows the entity facing away from the team for approximately forty seconds.
It then spoke using the voice of the missing police sergeant.
«“There are only seven of you now.”»
The task force consisted of eight members.
The rear member disappeared from the formation less than three seconds later.
The footage did not capture SCP-9476 moving.
Containment required:
* four mobile task force units;
* cryogenic weapons;
* industrial cutting equipment;
* and the controlled collapse of two tunnel sections.
During transportation, SCP-9476 remained unconscious for approximately nineteen hours.
When it awakened, it immediately attempted to imitate the sound of the transport vehicle’s electronic door lock.
---
+ Addendum 9476-1: Initial Examination
Early medical scanning produced inconsistent results.
X-ray imaging showed no fixed skeleton.
Instead, SCP-9476 contains hundreds of temporary cartilage structures capable of changing position.
Magnetic resonance scanning caused several internal organs to relocate away from the scanner’s strongest field.
Ultrasound examination revealed hollow spaces inside the torso, but the size and location of these cavities changed between scans.
One cavity appeared to extend beyond the physical dimensions of the entity.
A probe inserted twelve centimetres into the cavity continued travelling for more than four metres before its signal was lost.
The cable was recovered with {{63 cm}} missing.
The severed end displayed signs of:
* corrosion;
* freezing;
* and biological decomposition.
These effects appeared to have occurred simultaneously.
Further internal probing was prohibited.
---
+ Addendum 9476-2: Behavioural Test
Test Purpose: Determine whether SCP-9476 can identify living organisms without direct visual confirmation.
A heated mannequin was placed inside the chamber.
SCP-9476 approached but did not attack it.
A recorded human heartbeat was played through a speaker inside the mannequin.
The entity touched the mannequin’s chest and remained motionless for eleven seconds.
It then turned toward the observation wall and stated:
«“That one has no fear.”»
A live rat was released behind a sealed panel.
SCP-9476 immediately faced the panel and extended one external tendon through a drainage opening.
The test was terminated.
---
+ Addendum 9476-3: Interview Attempt
Interviewer: Dr. Elian Voss
Subject: SCP-9476
«Dr. Voss: Can you understand me?
SCP-9476: Understand me?
Dr. Voss: Do you know where you are?
SCP-9476: Inside.
Dr. Voss: Inside what?
SCP-9476: The smaller room.
Dr. Voss: What is the larger room?
SCP-9476: You.
Dr. Voss: What are you?
SCP-9476: What remains after the shape is removed.
Dr. Voss: Were you once human?
SCP-9476: Human is a position.
Dr. Voss: What does that mean?
SCP-9476: You are standing in it.
Dr. Voss: Why do you consume living organisms?
SCP-9476: To remember movement.
Dr. Voss: Do you need to eat?
SCP-9476: Need is what the mouth tells the body.
Dr. Voss: Do you have a name?
SCP-9476: You gave me four numbers.
Dr. Voss: Is SCP-9476 acceptable?
SCP-9476: It will open eventually.
Dr. Voss: What will open?
SCP-9476: The part of you facing inward.»
At this point, SCP-9476 placed both hands against its closed mouth.
Every microphone in the containment wing recorded a second voice despite the entity’s mouth remaining motionless.
The voice belonged to Dr. Voss.
«“Stop asking it questions.”»
Dr. Voss ended the interview.
No evidence of audio manipulation was identified.
---
+ Addendum 9476-4: Containment Incident
On {{██/██/20██}}, a maintenance fault caused the chamber cooling system to shut down.
The internal temperature increased from 6°C to 19°C over forty-three minutes.
SCP-9476 remained motionless until technicians entered the external maintenance corridor.
The entity then pressed its head against the northern wall.
Its mouth opened directly into the wall surface.
Thermal imaging showed tissue entering microscopic fractures in the containment plating.
Within four minutes, organic material reached the opposite side.
A technician reported hearing their mother’s voice from inside the wall.
The technician approached despite repeated orders to withdraw.
A tendril emerged from an electrical conduit and pulled the individual into the wall cavity.
The opening measured seven centimetres across.
The technician’s body was never recovered.
SCP-9476 subsequently increased in mass by approximately {{48 kg}} and developed temporary human-like fingers on its right hand.
It breached the primary chamber thirty-one minutes later.
Security footage showed SCP-9476 moving through the containment sector while imitating emergency instructions.
Several personnel followed the false announcements into sealed corridors.
The entity deliberately separated groups before attacking.
During the breach, SCP-9476 avoided heavily armed security personnel unless they blocked its route.
Its apparent objective was the site’s central ventilation system.
SCP-9476 was stopped after ultraviolet arrays were activated simultaneously with cryogenic foam dispersal.
It was found frozen around a ventilation intake, with half of its torso flattened through a gap less than twelve centimetres wide.
Three days after recontainment, SCP-9476 spoke through a disabled camera speaker:
«“The building breathes while you sleep.”»
The camera was not connected to power.
---
+ Addendum 9476-5: Origin Hypotheses
++ Hypothesis One — Mutated Organism
SCP-9476 may be a heavily altered biological organism created through unknown experimentation.
This theory is supported by its humanoid structure, adaptive tissue, and apparent familiarity with human infrastructure.
No laboratories or relevant records were discovered near the recovery location.
++ Hypothesis Two — Mimetic Predator
SCP-9476 may have evolved specifically to hunt intelligent organisms by studying communication, movement, and emotional responses.
Its humanoid form may be imitative rather than natural.
This could explain its ability to reshape itself after consuming tissue.
++ Hypothesis Three — Extradimensional Organism
The inconsistent internal dimensions of SCP-9476 suggest that part of its anatomy may exist outside conventional space.
Its visible body may function as:
* an entrance;
* a feeding organ;
* or a projection of a larger entity.
Under this interpretation, its mouth is not a digestive opening.

++ Hypothesis Four — Incomplete Human Transformation
Recovered tissue samples contain unstable genetic sequences resembling fragments from multiple humans.
None form a complete genome.
SCP-9476 may be the result of several organisms being merged, copied, or reconstructed incorrectly.
The entity’s statement that //“human is a position”// has been cited in support of this theory.
++ Hypothesis Five — Self-Creating Organism
SCP-9476 may not possess an original form.
It may continuously construct itself using:
* observed organisms;
* consumed tissue;
* environmental structures;
* and reactions from witnesses.
Under this theory, every attempt to understand SCP-9476 contributes to what it becomes.
Research into this possibility is restricted.

+ Addendum 9476-6: The Mouth Event
During a routine observation period, SCP-9476 stood motionless for nine hours.
At {{03:17}}, it opened its mouth.
The opening continued expanding beyond all previously observed limits.
The head, neck, chest, and upper abdomen unfolded into a single cavity approximately two metres across.
The interior did not reflect containment lighting.
Cameras directed into the cavity recorded a long corridor resembling a section of Site-19.
The corridor did not correspond to any current architectural plan.
Several figures were visible standing at the far end.
One appeared to be Dr. Voss.
At the time, Dr. Voss was observing the event from the control room.
The figure inside SCP-9476 raised its hand.
Dr. Voss raised his own hand simultaneously and later claimed the movement was involuntary.
The figure then opened its mouth.
All chamber cameras failed.
When surveillance systems returned, SCP-9476’s body was closed and Dr. Voss was unconscious.
A dark horizontal scar had appeared across his lower face.
Medical personnel found no physical injury beneath it.
For four days, Dr. Voss refused to speak.
When eventually questioned, he wrote:
«“Its mouth is not part of its body.”
“Its body is the thing preventing the mouth from opening.”»
Dr. Voss was transferred from the project.
His current location is classified.

+ Addendum 9476-7: Updated Risk Assessment
SCP-9476 was previously considered a highly adaptive predatory organism.
Current evidence suggests this assessment is incomplete.
The creature’s visible body may serve several purposes:
* It limits the size of the internal anomaly.
* It allows the anomaly to move through physical space.
* It provides a recognisable form that causes observers to interpret it as an organism.
* It may prevent whatever exists inside the mouth from fully entering reality.
Damage to SCP-9476 may therefore carry an unknown risk.
Termination attempts have been suspended indefinitely.
Containment personnel are reminded that SCP-9476’s body is not necessarily the primary threat.
«The entity may itself be a container.»

+ Final Containment Note
SCP-9476 does not sleep.
It does not breathe unless observed.
It does not eat because it is hungry.
It does not imitate voices because it wishes to communicate.
It studies humans because every living organism it encounters provides another structure, sound, movement, or emotion that it can reproduce.
The longer SCP-9476 remains contained, the more accurately it learns to behave like something that belongs inside the facility.
The entity has recently begun standing near its chamber door during shift changes.
It places one hand against the metal and speaks in the voice of whichever guard is approaching.
It always says the same sentence:
«“You can stop watching now. I know how to be you.”»
Few weeks pass by and it started to try and get into others containment cells.

|alt-text=]]Excerpts of Note from Rev. 0:
There had been no scream, impact, or visible movement.
He had simply been removed from the formation.
The sound it produced was not a roar.
It sounded like multiple people attempting to breathe through the same throat.
The entity did not move like an animal.
It moved like something changing its shape to match the space around it.
It does not consume living organisms because it is hungry.
It consumes them because each body teaches it something new.
Excerpts of Note from Final Rev.:
In addition to sight, SCP-9476 detects its environment through:
- vibration;
- temperature;
- electrical activity;
- sound;
- and an unidentified mechanism capable of locating living organisms through reinforced walls.
Observed effects include:
- increased muscle density;
- additional digits;
- temporary fur-like fibres;
- altered joint structure;
- new vocalisations;
- and changes in body temperature.
Addendum 9476-5: Origin Hypotheses
Hypothesis One — Mutated Organism
SCP-9476 may be a heavily altered biological organism created through unknown experimentation.
This theory is supported by its humanoid structure, adaptive tissue, and apparent familiarity with human infrastructure.
No laboratories or relevant records were discovered near the recovery location.
Hypothesis Two — Mimetic Predator
SCP-9476 may have evolved specifically to hunt intelligent organisms by studying communication, movement, and emotional responses.
Its humanoid form may be imitative rather than natural.
This could explain its ability to reshape itself after consuming tissue.
Hypothesis Three — Extradimensional Organism
The inconsistent internal dimensions of SCP-9476 suggest that part of its anatomy may exist outside conventional space.
Its visible body may function as:
- an entrance;
- a feeding organ;
- or a projection of a larger entity.
Under this interpretation, its mouth is not a digestive opening.
