SCP-3839 gains control over lipids not part of itself within an 
approximate radius of 3 m; at greater distances, SCP-3839 can only 
exert a weak attractive force whose strength exponentially 
decreases with distance. SCP-3839 is capable of restructuring lipids 
into various shapes and structures, usually in the shape of crude 
hands, arms, or mouths. 


When not moving, SCP-3839 emits a yellow cloud composed of 
aerosolized lipids and proteins, most of which are unseen in ordinary 
organisms. Inhalation or skin absorption of these products causes 
an anomalous effect on humans in its vicinity; nearly all humans 
begin to lose their self-preservation instinct within 1 minute of 


Dr. Gibbons has requested two (2) pills of SCP-500 for his personal 
medkit. Request denied. 


Addendum 500-1: Two (2) pills have been authorized for use with 
SCP-008. As a result of conducting a series of tests on Class D 
subjects infected with SCP-008, it appears that even in the most 
advanced stages of the disease one whole pill will accomplish full 
recovery. Number of pills is fifty-seven (57) at the time of writing. - 
Dr. [500-0021D] 


Addendum 500-2: One (1) pill has been authorized for use with 
SCP-409. SCP-500 was tested on Subject 409-D5 who was 
exposed to the effects of SCP-409. Complete recovery 
accomplished. See Addendum 409-1. Number of pills is fifty-six (56) 
at the time of writing. - Dr. [500-0021 D] 


Addendum 500-4: Request 500-1774-k approved. Five (5) pills 
have been used in experimentation with SCP-038. It has been 
determined that SCP-038 is capable of duplicating SCP-500; 
however, the success of the duplicated pills is limited. The 
duplicated pills are only effective in curing the subject 30% of the 
time, with chance of successful healing dropping as time since 
cloned increases. In 60% of the cases where the infection is 
permanent, symptoms of infection remain, though further infestation 
is neutralized. Repeated dosing with SCP-038 cloned pills is 
recommended for all personnel suffering from incurable conditions, 
as supply of SCP-500 remains extremely limited. All five (5) used 
samples of SCP-500 were returned. Number of pills is fifty-six (56) 
at the time of writing. 


Addendum 500-5: During experiments with SCP-038, one (1) pill 
was stolen by personnel D- to, reportedly, "cure a hangover". 
Stricter controls for samples of SCP-500 given to other projects is 
suggested. Personnel D- has been terminated. Number of pills is 
fifty-five (55) at the time of writing. 


Addendum 500-6: One (1) pill has been used with SCP-231-4. 
Number of pills is fifty-four (54) at the time of writing. 


Addendum 500-7: One (1) pill has been used for Experiment 447-a. 
Number of pills is fifty-three (53) at the time of writing. 


exposure, and all fear response pathways completely shut down 
within 8 minutes. Autopsies of recovered subjects has revealed the 
formation of small growths of sphingomyelin’ in the amygdala2, 
encasing and absorbing neurons and glial cells. 


SCP-3839 will then attempt to catch affected humans with its limbs. 
Once SCP-3839 has gripped a human with its appendage, 
SCP-3839 will extend a smaller, tube-like appendage and expel a 
thick slurry from it until it hits the targeted human. When this slurry 
comes in contact with human tissue, it reverts human osteocytes, 
chondrocytes, myocytes, and adipocytes$ into mesenchymal stem 
cells, with complete conversion normally occuring within four 
minutes‘. These stem cells will differentiate into a new form of 
adipocyte, which coagulate into a homogenous mass and absorb 
the remaining neurons. SCP-3839 will then proceed to move itself 
towards the remains and absorb the new adipocyte mass into itself, 
leaving the remainder behind. 


Biopsy of the outer mass of SCP-3839 has shown that it possesses 
genetic material from 36 humans, 9 of which match to former 
Prometheus Labs personnel, most notably Dr. ,Dr. —, and Dr. 
Javier Pineda. 


CT scanning of SCP-3839 revealed a large mass in its center; this 
mass appears to be composed of a dense network of neurons 
arranged in 37 discrete clusters. 35 of these directly link to a larger 
cluster in the center of the mass, with smaller links between each 
other. The 37th is isolated from all other clusters and encased in a 
crystalline shell. This shell is composed mainly of crystalline fat and 
appears to be in a constant state of equilibrium, being dissolved 
from without and reconstituted from within. All clusters have 
exhibited significant neural activity, with the central cluster and 
cluster 37 the most active. Tests using isotopic labeling have shown 
that upon conversion and ingestion of a human subject, a new 
cluster will form from the subject's neurons. 


Brain biopsies have determined that SCP-3839's clusters are 
composed of a new form of brain matter, with specialized adipocytes 
replacing ordinary glial cells. 


SCP-3839 will occasionally enter an Eglah state, growing a single 


large appendage and occasionally manifesting crystalline spikes or 
various liquids from the end. SCP-3839 will then attack itself with 
this appendage. SCP-3839 sustains no lasting damage during these 
states; any damage is quickly repaired by SCP-3839 rearranging its 
mass to fill the wounds. Notably, SCP-3839 will usually form a 
thickened mass of compacted fat to protect its clusters. This state 
ends when the appendage either retracts or is severed. 


The time interval between Eglah events has steadily increased over 
time; rising from an average of 2 days upon initial containment in 
2000, to 3 weeks. However, the duration has increased from 10 
minutes to over an hour as of the most recent event. 


Eglah events have become increasingly destructive during 
SCP-3839's time in containment. Recently, SCP-3839 has begun to 
show signs of increasing intelligence. 


Addendum 3839-A: Notable Eglah Events 


For the sake of clarity, the hostile appendage will be designated 
SCP-3839-ALPHA. 


Event Number Duration Notes 

12 13 minutes First recorded 
instance of 3839- 
ALPHA attempting to 
play dead to launch a 
second attack. 3839- 
ALPHA was torn from 
3839's mass, ceased 
motion completely, 
and was reabsorbed 
after 2 minutes. 

122 15 minutes 3839-ALPHA attached 
itself to the ceiling 
using an adhesive 
substance exuded 
from its end. It then

repeatedly slam it 
against the floor and 
walls of the cell. 3839 
suffered severe blunt 
force trauma after 7 
hits, at which point 
3839-ALPHA 
experienced structural 
failure and separated 
from 3839. 3839- 
ALPHA was removed 
from the ceiling and 
reabsorbed by 3839. 
A sample of the 
adhesive was 
successfully taken for 
study. 

First recorded 
instance of 3839 
growing human-like 
hands on the ends of 
its appendages. 

First recorded 
instance of 3839- 
ALPHA using 
chemical attacks, 
specifically, an organic 
chemical agent 
intended to induce 
apoptosis in fat Cells. 
First recorded 
instance of 3839 
emulating human 
vocalizations. 3839 
vocalized ina 
distorted female voice,

3839 extended an 
appendage and 
breached the NaOH 
sprinklers directly 
above 3839-ALPHA, 
destroying it. First 
recorded instance of 
3839 using its cell to 
its advantage. 
Containment layout 
has been updated. 
First recorded 
instance of 3839 
attempting to address 
personnel during an 
Eglah event. 3839 
spoke in a deeper, 
distorted voice and 
was recorded as 
saying "He was a 
fool.” 

Final Eglah event. 
3839-ALPHA formed a 
roughly humanoid 
shape and attacked 
3839 repeatedly, 
ignoring all damage 
inflicted to itself by 
3839's counterattacks. 
Just before reaching 
the center cluster of 
3839, 3839-ALPHA 
was forcibly torn from 
3839's main body, and 
repeatedly slammed 
into the ground and 
walls until finally being 
ripped apart by 3839 


and absorbed. Upon 
absorption, 3839 
moved jerkily and 
erratically for 9 
minutes before 
collapsing into a near- 
liquid state. 3839 
regained its previous 
form after 2 days. 


Update / /14: Eglah events have ceased completely, and 
SCP-3839 has become more docile in temperament. SCP-3839 has 
begun to occasionally split a portion of its mass off and attempt to 
shape it. These constructs have been designated SCP-3839-BETA. 
SCP-3839-BETA instances usually have a crude humanoid shape 
but tend to rapidly collapse into a pile of fat. Instances that do not 
collapse are eventually reabsorbed by SCP-3839. 


SCP-3839-BETA instances have gradually become more refined 
over time, and last longer before collapse and reabsorption. 


Update / /18: All new instances of SCP-3839-BETA vaguely 
resemble the late Dr. Pineda, and are fully mobile. These 
SCP-3839-BETA instances are capable of locomotion and distorted 
vocalization, and generally attempt to move towards the cell's 
camera or observation ports.

SCP-3840: We Stand On Guard For Thee 


Item #: SCP-3840 
Object Class: Keter 


Special Containment Procedures: Due to the size of the area 
SCP-3840 can manifest in, the entity cannot be physically 
contained. Containment will focus on disseminating fictional 
accounts of SCP-3840 sightings, intending to convince the general 
population that information pertaining to the anomaly is derived from 
an urban legend, along with explanations that attribute sightings to 
native fauna or hallucinations. Amnestics may be administered if 
witnesses attempt to heavily spread information on SCP-3840. 


As radio broadcasts from the object are interpreted as number 
station broadcasts and are only known to fringe groups, further 
containment on these is unnecessary. 


Revision: Attempting communication with SCP-3840 is forbidden. 


Description: SCP-3840 is an emaciated humanoid entity that 
manifests in the Boreal forest region of Canada. It appears to be 
covered in severe burn wounds and is estimated to be 2m in height. 
Manifestations involve SCP-3840 being ejected out of a section of 
the forest, reaching a height of 50m above the canopy, and 
descending to another forested section 20m away. 


This process will repeat for a variable length of time, normally 
around three minutes though reaching an hour on occasion, during 
which SCP-3840 moves toward the nearest population center until 
reaching a distance of 20km from the location. Demanifestation has 
not been directly observed. Of note is that, at all points during 
movement, SCP-3840 appears to be largely limp. 


Certain objects that enter an undetermined radius around SCP-3840 
will be pushed by an unseen force into following the same "leaping" 


motions as the entity, invariably colliding with trees or the ground in 
the process. These objects will vanish when SCP-3840 demanifests, 
and do not appear in subsequent manifestations. The most 
frequently observed objects seen alongside the entity are deceased 
animals, damaged articles of clothing, and computers. 


Shortwave radio broadcasts at a frequency of 2156 kHz are 
released from SCP-3840 when manifested. These broadcasts 
consist entirely of a repeating monotone buzzing sound. A sample of 
this audio is below. WARNING: As this file may be loud, personnel 
are advised to lower the volume before listening. 


No variations have so far been observed. 


Sightings of entities similar to SCP-3840 have been reported. The 
most common describe a humanoid rapidly flying through a forested 
area, frequently colliding with trees while followed by indiscernible 
objects. An investigation is in progress. 


Addendum: On 21-August-2015, Foundation assets began 
detecting a stationary radio broadcast at 2156 kHz, originating from 
Spray Valley Provincial Park in Alberta, Canada. The signal 
consisted entirely of a female voice repeatedly saying "Hello?" in 
English and French. After twelve hours the broadcast ceased, and 
undercover Foundation operatives were dispatched to the location. 


Operatives discovered a camp site within a forested area. A heavily 
damaged camping van and the remains of a makeshift radio tower! 
were present at the location, along with burnt articles of clothing. 
Cyrielle Mercier, a member of multiple online conspiracy theory 
forums, and a cell phone that belonged to an acquaintance were 
found inside the van. 


Relevant files are available below. 
> Investigation 3840/10 Recovered Files 


The following are files recovered from the cell phone 
found with Mercier. A majority of data on the phone was 
corrupted.

Description: Four young 
individuals, including Mercier, 
stand next to each other in front 
of the camper van. All of them 
have their arms placed on each 
other's shoulders and are smiling. 
A male subject holds a white sign 
with "parawatch. "2 written on it 
in black paint. A male individual 
(hereafter Subject 1) is drinking 
from a beer bottle, holding it ina 
comedically exaggerated manner. 
Several cell phones, ear buds, 
and portable chargers are 
suspended in the air above them. 


NOTE: Due to the reluctance of 
Mercier to provide information, 
the names of these individuals 
are not known.
