SCP-939: With Many Voices Part 1

Item #: SCP-939

Object Class: Keter

Special Containment Procedures: SCP-939-1, 3, 19, 53, 89, 96, 98, 99, and 109 are kept in Cell 1163-A or 1163-B, 10m x 10m x 3m containment chambers within Armed Bio-Containment Area-14. Both cells are environmentally regulated and negatively pressurized, with walls constructed of reinforced concrete. Access to these cells is regulated by an outer decontamination chamber and inner gas-tight steel security doors. Observation windows are constructed of laminated ballistics glass 10 cm in thickness protected by a 100kV electrified mesh. Humidity is maintained at 100% at a temperature of 16°C. Specimens are monitored at all times via infrared cameras. Level Four authorization is required to access SCP-939, their containment areas, or the observation chambers.

SCP-939-101 is dismembered and stored in Cryogenic Preservation Tanks 939-101A to 939-101M within Bio-Research Area-12. Access to SCP-939-101 requires authorization by two Clearance Level 3 personnel, one of which must be present for all research and testing. The contents of only one (1) 939-101 tank may be accessed at any given time. Core temperature of SCP-939-101 tissues must be monitored while removed from cryogenic preservation; should core temperature exceed 10°C, tissues are to be returned to their corresponding tank and all testing suspended for a period of seventy-two (72) hours. Barring core temperature exceeding 10°C, research of SCP-939-101tissues may continue as long as its ramblings and pleas for release may be tolerated.

Containment cells need to be cleaned biweekly. While this takes place, SCP-939 specimens will be transferred to the adjacent cell. During this time, the cell's door and observation window must be inspected for damage and repaired or replaced accordingly.

Heavy sedation of all SCP-939 is required before any interaction, including transfer between cells and experimentation, may take place. See Document #939-TE4 for transfer and experimentation protocol.

Level C Hazmat gear is to be worn by personnel during interactions with SCP-939 specimens and in any areas which SCP-939 have been known to inhabit. Afterward, standard decontamination procedures are to be observed by all personnel to ensure no secondary spread of amnestic agents occurs.

Following Incident ABCA14-939-3, all non-Class D personnel interacting with SCP-939 for any length of time are required to wear two (2) water-proof electronic pulse monitors for the duration of such interaction. These pulse monitors will transmit to a wireless monitoring system independent of a facility's main power grid, with at least one backup power system on standby. Should both an individual's pulse monitors flat-line or otherwise malfunction, the wearer will be presumed dead, personnel are instructed to disregard all of the wearer's subsequent vocalizations, and a breach of containment is declared automatically. Security personnel responding to such a breach are likewise required to wear these pulse monitors.

Additionally, all live SCP-939 specimens must be implanted with subdermal tracking devices upon capture.


Description: SCP-939 are endothermic, pack-based predators which display atrophy of various systems similar to troglobitic organisms. The skins of SCP-939 are highly permeable to moisture and translucent red, owing to a compound chemically similar to hemoglobin. SCP-939 average 2.2 meters tall standing upright and weigh an average of 250kg, though weight is highly variable. Each of their four limbs end in three-fingered claws with a fourth, opposable digit, and are covered in setae which considerably augment climbing ability. Their heads are elongated, devoid of even vestigial eyes or eye sockets, and contain no brain casing. The jaws of SCP-939 are lined with red, faintly luminescent fang-like teeth, similar to those belonging to specimens of the genus Chauliodus (Viper fish), up to 6cm in length, and encircled by heat-sensitive pit organs. Eye spots, sensitive to light and dark, run the length of their spined dorsal ridges. These spines may be up to 16cm long and may be sensitive to changes in air pressure and flow.

SCP-939 do not possess many vital organs systems; central and peripheral nervous systems, circulatory system, and digestive tract are all absent. SCP-939's respiratory system is atrophied and serves no apparent purpose beyond spreading AMN-C227 (see below). SCP-939 have no apparent physiological need to feed, nor any way to digest consumed tissue. Ingested material typically accumulates in the respiratory system of SCP-939 and is regurgitated once the amount is sufficient to markedly inhibit its function. Despite the absence of many vital organ systems, SCP-939 is capable of bearing live young. See Addendum 10-16-1991.

SCP-939's primary method of luring prey is the imitation of human speech in the voices of prior victims, though imitation of other species and active nocturnal hunts have been documented. SCP-939 vocalizations often imply significant distress; whether SCP-939 understand their vocalizations or are repeating previously heard phrases is the subject of ongoing study. How SCP-939 acquire voices is not currently understood; specimens have been documented imitating victims despite never hearing the victim speak. Analysis of SCP-939 vocalizations cannot distinguish between SCP-939 and samples of of known victims' voices. The use of biometric voice recognition security or identification systems at any installation housing SCP-939 is strongly discouraged for this reason. Prey is usually killed with a single bite to the cranium or neck; bite forces have been measured in excess of 35 MPa.

SCP-939 exhale minute traces of aerosolized Class C amnestic, designated AMN-C227. AMN-C227 causes temporary anterograde amnesia, inhibiting memory formation for the duration of exposure, plus an average of thirty (30) minutes. It is colorless, odorless, and tasteless with an estimated ECt50 for inhalation of 0.0015mg•min/m³. In well-ventilated or open air environments, risk of exposure to ECt50 is greatly reduced, but not negligible. AMN-C227 is typically undetectable in the bloodstream sixty (60) minutes following cessation of exposure Reported sensations of disorientation and mild hallucinations immediately following removal from environments saturated with the agent are similar to recreational use of psychoactive substances and easily mistaken as such.

Addendum 11-14-1981: A log of radio traffic between teams during initial contact with SCP-939.

Initial Contact Log SCP-939

The following is a transcript of radio traffic between the on-scene commander (Trapper Home) and subordinate fire teams (Trapper 1, 2, and 3) of Site-██'s tactical contact security force designated "Trapper" during the initial contact with and recovery of SCP-939. Trapper was deployed to the outskirts of ████████, ████████ on 10/28/1981, following the disappearance of a Foundation field agent. The agent was investigating a number of localized missing persons cases, as well as the loss of contact with several law enforcement officers dispatched to investigate these cases in the area.

<Begin Transcript>

Trapper Home: Alright, let's get those comm checks people. Those field masks were giving your VOX a hell of a time last time out.

Agent Washburne (Trapper One Lead): Trapper Home, Trapper Two, Trapper Three, this is Trapper One, radio check, over.

Agent Michaels (Trapper Two Lead): Lima Charlie, One.

Agent Shandrick (Trapper Three Lead): Gotcha, One.

Trapper Home: All stations, I have you loud and clear. Be advised, your teams are go for entry. Trapper One, weapons tight.

Agent Washburne (T1L): Solid copy, Home. Three, stand by with Home, you know your job. Two, keep your team tight on my flank after we breach.

Agent Michaels (T2L): Copy, One.

Agent Washburne (T1L): One, stack up.

<Members of Trapper One can be heard acknowledging Trapper One's Lead's command.>

Agent Washburne (T1L): Execute.

Agent Nicholas (Trapper One): All right, that water charge goes in 5.

<Water charge detonates>

Agent Nicholas (T1): Stairs, front! Clear left!

Agent Roland (Trapper One): Door, right! Right side, clear!

Agent Michaels (T2L): Overhead clear.

Agent Harrison (Trapper Two): Thompson, on me. Cross. Room clear.

Agent Washburne: Trapper Home, Trapper One and Two reporting no contact. Two, secure that passage way, mark your territory, and then follow my team down. Keep an eye out for our man and call it when you come down; I don't want any blue on blue, solid?

Agent Michaels (T2L): Copy, One.

Agent Washburne (T1L): Hoskins, you've got point.

Agent Hoskins (Trapper One): Roger that. Movin' up.

Agent Washburne (T1L): Trapper Home, this is One; be advised we are moving further into the structure, down a ladderwell, over.

Trapper Home: Solid copy, One. Proceed, over.

<Members of Trapper One can be heard calling out doorways and landing as they move further down the stairs.>

Agent Washburne (T1L): Trapper Home, be advised: I'm starting to smell something rotten down here and it's pretty strong. Something's been dead for a while… stand by… Team, halt. Home, I'm looking at some shredded clothing down here. No bodies, just the clothes, and nothing that looks like our man. There's the cop…

Agent Hoskins (T1): Jesus man, look at that… it looks like something just took a huge bite outta that vest…

Trapper Home: Lock it up down there, One. Washburne, get back on track.

Agent Washburne (T1L): Copy, Home. Trapper Two, watch yourselves. Something around our pos has an appetite and it looks like it's got a pretty mean bite.

Agent Michaels (T2L): Solid, One. We're almost done up here. If our Agent is here, he's down there with you guys. We'll be down as soon as we -

<A muffled human voice is audible through Agent Washburne's VOX feed, unintelligible and distant.>

Agent Washburne (T1L): One and Two, freeze.

Unknown Voice: Help me! Jesus Christ! Somebody!

Agent Washburne (T1L): Home, Two, I think we got our man. Hustle up, people.

<Trapper One can be heard moving quickly through the structure. The cry for help is again audible.>

Agent Washburne (T1L): Home, we've reached the source of the noise. We're about to get our Agent back. Two, have Doc prep the trauma bag; this guy sounds like he's in bad shape. Hoskins, do it!

<Two shotgun reports, sound of door slamming on floor>

<Immediate sustained gunfire>

Agent Washburne (T1L): Home, contact! Two, get the fuck down here! Roland, pull back!

Agent Nicholas (T1): Hoskins is down! Shit!

Agent Washburne (T1L): Roland, on your right! Two, hurry the fuck up!

Agent Michaels (T2L): One, what the hell is going on down there?

<Gunfire ceases>

Agent Michaels (T2L): Trapper One! Sound off!

Agent Washburne, shouting off comm: Two, get the fuck down here, Hoskins is down! Hurry the fuck up!

Agent Michaels (T2L): Copy, One! Harrison, Thompson, you're coming with me. Gabardi, stay with Doc.

<Trapper Two can be heard acknowledging Trapper Two Lead's order.>

Agent Michaels (T2L): Home, One, be advised, Two is en route to One's last position.

<Agent Washburne can be heard cursing over Agent Michael's VOX feed.>

Agent Michaels (T2L): One, be advised, your radio's not broadcasting; I can hear you, but you're- JESUS CHRIST! TWO, ENGAGE, ENGAGE!

<Immediate sustained gunfire>

Agent Michaels (T2L): Thompson, pick up the slack. Loading! Gun up! Guys, pull it back down the hallway. Harrison, suppress that doorway. Frag out!


Agent Michaels (T2L): Gabardi, Doc, get the 60 set, we're coming up. Trapper One's gone and I'm dropping gas. Mask up. GAS GAS GAS!

<Three muffled popping sounds can be heard.>

Agent Michaels (T2L): Coming up the stairs!

Agent Harrison (T2): They're slowing down. Get Three, Michaels?

Agent Michaels (T2L): Home, we've deployed VX and need Three down here in MOPP for cleanup. Set up decon.

Agent Shandrick (T3L): Roger, Two, we're already on our way.

Agent Gabardi (T2): SHIT!


Agent Michaels (T2L): Whoa… nice shot, Gabardi. Home, we've got an unconscious one. We're gonna need a mobile containment unit and medical support for the candidate. I think it sucked down some VX. I'm not hearing any more movement down those stairs, Home.

Trapper Home: Copy, Two. Standby for linkup with Three, extricate the candidate, and hit decon. We're done here.

<End Transcript>


Addendum 04-11-1982: Due to SCP-939's intense aversion to bright light, it has been deemed a minimal risk of escape. Standard fluorescent hallway lighting is sufficient to deter SCP-939-1 from leaving its darkened cell. See Addendum 09-20-1991


Addendum 06-29-1987: Preliminary research into AMN-C227 suggests potential for use as a general-purpose amnestic. Methods of mass-producing the agent, as well as possible adverse effects, are being investigated at Bio-Containment and Research Site-06.


Addendum 10-03-1990: AMN-C227 has been approved for use as a Class C amnestic. Projected annual production at Bio-Research Area-12 by SCP-939 respiratory tissue cultures is expected to surpass three (3) liters.


Addendum 09-20-1991: Containment of nine (9) SCP-939 specimens has been compromised following a "Silent Night" breach scenario at Bio-Containment and Research Site-06. Nearby civilian settlements have been evacuated on the pretense of a coming storm. Recovery teams have been deployed to the area.


Addendum 10-16-1991: [REDACTED] In light of this, all interaction with SCP-939 from September 8th to October 7th in the Northern Hemisphere or March 6th to April 4th in the Southern Hemisphere is strictly forbidden. [REDACTED] No male specimens of SCP-939 have yet to be identified [REDACTED] contain a Class B amnestic [REDACTED]

See Reproduction of SCP-939.


Addendum 02-20-1992: Effective immediately, use of AMN-C227 as an amnestic is suspended indefinitely. Consult Incident Report AMN-C227-939 for further information.


Addendum: Log from 682-F Termination Log

Item #: SCP-939-██ and SCP-939-███

  • Tissue Test Record: Not attacked by SCP-939-██ nor SCP-939-███

  • Termination Test Record: SCP-939-██ and SCP-939-███ both entered the containment cell for SCP-682. SCP-939-██ and SCP-939-███ were seemingly distressed and refused to attack SCP-682, while repeating a call for help. SCP-682 then attacked the two, devouring them after roughly and brutally mutilating the bodies of both subjects.

Notes: SCP-939 and SCP-682 don't match well. I guess we will not be using them anytime soon. Don't release the beasts again.
