Description: SCP-158 is a large mechanical arm, similar to one that 
one might find in an automotive factory, although the end 
attachment is unusually shaped, resembling a pointed tridactyl claw. 
Its optimal placement is to be installed and suspended upside down, 
its base attached to the ceiling in a room that has been built to 
accommodate. A series of cables are protruding from the base and 
some are connected to a complex mobile console, complete with 
VDU (Visual Display Unit) and full keyboard. The others should be 
connected to a working power supply if the device is to be operated 
successfully. At the bottom of the console, there is a dispensing 
device, with attachments for a container roughly 7.6 cm (3 in) in 
width, and 17.8 cm (7 in) in height. 


The arm, cables and console have sustained fire damage, though 
this is purely cosmetic, and does not affect the device's 
performance. 


When activated, the device will take twenty (20) minutes to boot up 


and become fully functional. 


When used correctly upon a living organism that displays cognition, 
SCP-158 will remove an unknown substance and transfer it through 
the dispensing device beneath the console. The optimum container 
for this substance is a glass jar or beaker that fits the attachments. 
After this action is performed, the organism that it was performed on 
will cease all higher brain functions, with only the activity in the brain 
stem continuing. The subject will not respond to external stimuli, and 
will not exhibit any movement beyond basic reflex actions. 


The substance removed is gaseous, though its overall appearance 
and properties differ from subject to subject. The substance is an 
indefinite source of kinetic, electrical, heat, and light energy. 
Although the rate and output, again, differ from subject to subject, 
the average is relatively low. 


The device was found in late 2007 in, , within a burned out 
hospital that had been in apparent disuse for a large, discernible 
period of time (rough estimations would put it at over five years). 
Along with the device was a badly damaged "owner's manual" which 
contained instructions on how to use the device. These instructions 
have since been transcribed and copied numerous times, with a 
single copy always present in the containment room. While the 
instructions clearly state how to maintain and use the device, the 
chapters chronicling who built it and what exactly it did were too 
badly damaged to be read, requiring a process of trial and error to 
find it (see Experiment Log 158-AA). 


Additional Notes: The device is also capable of reversing the 
extraction, placing the same, or a different, substance back into the 
subject (see Experiment Log 158-AG). When this action is 
performed, the subject will regain all cognitive and higher brain 
functions, but the total results differ, depending on whether or not it 
was the original substance extracted from the patient that was 
replaced. 


Addendum-01: Dr. suggests experimentation with D-class 
personnel and electronic equipment, to attempt to reproduce 
SCP-168, SCP-1875, SCP-2306, or similar phenomena. (Pending) 


Addendum-01A: Inspired by the previous Addendum, Regulator 
has hit on the ingenious notion of using SCP-158 on a test subject, 
then exposing the body to SCP-217 until the virus runs its course, 
and finally re-injecting the contents back into the transmogrified 
body. and are extremely excited about this proposal, and 
have arranged a meeting with all twelve of the to discuss the 
far-reaching benefits of such a technique.

Experiment Log 158 Aa 


Experiment Log of: Dr. Heinrich Driesch, a medical researcher 
assigned to SCP-158. 


Date: - -2008 
¢ Experiment-01: 


The device worked perfectly. It seems the damage to its casing was 
merely cosmetic. But more interesting was the substance extracted 
from Subject-001A. It's a dark brown in color, and is some strange 
cross between liquid and gaseous states. It should be analyzed in 
around an hour. Attempts to get the subject to show any sort of brain 
activity since has, as of yet, met with no progress. Still, no great loss 
there. 


¢ Experiment-02: 


This time, the substance was a light blue, and it seems more... 
active than the previous one. | wonder if it had anything to do with 
the difference in age... 


¢ Experiment-03: 


The test results came back, but they were inconclusive. They 
couldn't find anything. Literally. There were no signs that the 
substance even existed, apart from the steady emitting of light and 
heat. Anything else, nothing. 


Again, this subject has produced another different sample, different 
in color, and in the energy output. This is quite odd. 


* Experiment-06: 


There was a slight accident, involving my assistant, Lucy. I'm not 
sure how she managed it, but she knocked the sample from 
Subject-006B onto her laptop. The strange thing was, was that it 


was out of power before hand. Now, it's running, despite the fact 
both the plug and battery have been removed. However, there are 
some irregularities in its actions, small glitches, nothing serious. It 
makes me wonder. 


¢ Experiment-11: 


This is the last one for the night. This sample is different, just like all 
the rest, but I've been noticing some semblance of a pattern to it. 
After a few more experiments tomorrow, | believe I'll be able to 
elaborate. 


None of the subjects extracted from today have come out of the 
vegetative state. There's physically nothing wrong with them. 
Nothing at all. I've had them screened for every possible medical 
anomaly. They're just not there. Lights are on, but nobody's home. 
Still, despite this, I'm keeping them restrained and under guard, and 
Lucy's laptop, just in case. With the kind of things that go on around 
here, it's better to be safe than sorry. 


Date: - -2008 
¢ Experiment-24: 


| was right, there is a pattern to it. I'm almost certain the irregularities 
in the energy output are caused by the subject's age and vitality. As 
for the difference in colors, | think it may be down to the subject's 
disposition, but I'm not sure. | need to run a couple more tests, and 
get the original files on the subjects. 


Lucy's laptop is still running, despite not actually having a proper 
power supply for two days. There's no trace of the substance, 
internal or external. There's not even a mark on the casing. The 
irregularities are strange too. If left idle on a word processor, text will 
write itself, but it's gibberish. Still, it's an experiment that warrants 
some investigation. 


¢ Experiment-27: 


I've tried putting the substances obtained from the subjects into a 
variety of mechanical and electronic devices. The results are 


surprising. All of them have begun to work independently of an 
external power source. The ones of an electrical nature exhibited 
slight glitches of a intermittent nature. The mechanical items worked 
far more smoothly, although there was still the occasional oddity. 


The experimentation on the subjects continues. | think we'll stop 
when we go through around fifty. 


Date: - -2008 
¢ Experiment-45: 


The substances implanted in the objects have proven to be able to 
be removed from them using the machine. When they were 
extracted, they were exactly the same as beforehand, pre- 
implantation. We could use these as a type of infinite energy. But, 
we‘ have to find a way past the constant discrepancies in behavior. 


I've left the original one in Lucy's computer, much to her chagrin. 
The glitches seem to be getting more frequent, and more specific. 
Now, it opens the word processor itself, and types coherent 
sentences. I've saved them to file for research purposes. The 
camera and microphone activate themselves, and try and remain on 
regardless of attempts to turn them off. After a while of doing that, 
the word processor opened and typed out the words "QUIT IT YOU 
ASSHOLE". I'm submitting it for a Turing Test. 


Date: - -2008 
¢ Experiment-49: 


The laptop passed the test, and has displayed characteristics similar 
to Subject-O06B, the original donor, although subject states that it 
has no memory of the time past when it was interred in the laptop. 
This confirms my suspicions. Against all logic and scientific reason, 
SCP-158 is a device that extracts what most people would term a 
soul. This only opens up the possibilities for experimentation. This 
session, however, is over. 


Notes: Dr. Driesch is promoted to the head of studies regarding 
SCP-158. Further experimentation on SCP-158 and its products will 


continue. 


SCP-159: The Perfect Lock 


Item #: SCP-159 
Object Class: Safe 


Special Containment Procedures: SCP-159 is currently kept in a 
Secure Storage Locker at Site- . Knowledge of SCP-159 is 
restricted to those of Level-3 or higher, and access is restricted to 
Level-4 or higher. SCP-159 may not be used by any personnel 
except for extenuating circumstances. O5 command may order 
SCP-159 to be moved at any time that it becomes necessary to use 
SCP-159 to prevent a destructive scenario. 


In the event that SCP-159 is utilized in this way, it is to be powered 
by a dedicated high-efficiency generator and a spare supply of fuel 
is to be kept on hand. There is to be at least two personnel on 
standby during SCP-159's operation at all times. 


Description: SCP-159 has the appearance of a standard neon sign 
reading 'OPEN', of the style commonly found in small businesses. 
When SCP-159 is displayed through a window of a building, and 
deactivated by removing it from a standard power outlet!, the 
building will become impossible to enter by any means. The locking 
effect ceases immediately when SCP-159 is reattached to a power 
outlet. If SCP-159 is switched OFF and then removed from its power 
outlet, its effect will not activate. 


When SCP-159's locking effect is active, the structure which it is 
displayed within will become effectively indestructible from the 
outside. Building materials will withstand forces that would normally 
destroy them, up to and possibly surpassing moderate artillery 
bombardment. The affected structure will remain completely 
undamaged; testing has shown that protected structures will be 
unharmed by heat, hurricane-speed-winds, kinetic force, 
undermining, tunneling, explosive charges placed on the outside of 
the structure, electrical current, microwave, ultraviolet, X-Ray, 


neutron, and gamma radiation, and vehicular impact. Persons within 
a structure affected by SCP-159 may leave at any time, but may not 
re-enter until 159 is deactivated. The effect persists if windows, 
doors, and other portals are opened, with outside forces continuing 
to yield as if they were closed. 


Buildings affected by SCP-159 will continue to receive utilities such 
as running water and electricity; however, supplies will be strained of 
foreign materials and chemicals upon entering SCP-159's 
boundaries. Additionally, a buffering effect appears to prevent forces 
such as shockwaves and extremely high heat from penetrating the 
surface of the affected building. D-Class within the structure during 
artillery tests reported that the concussive forces rendered by test 
weaponry was greatly muted to the point that an open container of 
water did not react. 


If a piece of SCP-159's tubing expires, it may be replaced by a 
matching part. SCP-159's effect will manifest whether or not there is 
neon tubing installed. Personnel are to replace SCP-159's neon 
parts if they fail. SCP-159 will fail to activate if it is unplugged during 
a power outage.

SCP-160: Predator Drone 


Item #: SCP-160 
Object Class: Euclid 


Special Containment Procedures: SCP-160 is kept in a secure 
bio-containment chamber at Site .SCP-160 is to be fed live prey in 
the form of a rabbit or other animal of similar mass once per week, 
with feeding to be performed via automated delivery system only. 


Experimentation with SCP-160 may only be performed with prior 
permission from at least two (2) Level 3 personnel, and any 
personnel entering the chamber must wear an armored suit at all 
times. 


Description: SCP-160 appears to be a quadriflyer unmanned aerial 
vehicle (UAV) with a diameter of approximately 1.1 m at its widest 
point, similar to the [REDACTED] model manufactured by the 
[REDACTED] Corporation. It is devoid of any identifying marks or 
manufacturing labels, though visual inspection of SCP-160 has 
revealed signs of scratches and other superficial damage indicating 
that prior identifying labels may have been removed. 


SCP-160 operates continuously and completely autonomous from 
any identified control source, and exhibits behavior similar to that of 
predatory birds. It will actively hunt prey such as rodents and other 
small animals and, upon locating such prey, dive down at high 
speed and impale its prey with what appears to be a metallic 
proboscis. Analysis of its prey shows that it then injects a highly 
caustic substance that liquefies the internal organs, and extracts the 
resulting slurry. SCP-160 will generally avoid humans and larger 
animals, but has been recorded using its proboscis in self-defense. 
Injuries inflicted by SCP-160 are extremely painful, and can cause 
death via liquefaction of vital organs or internal bleeding. 


Further research on SCP-160 is underway, but has proven difficult 


due to SCP-160's continuous operation. Tranquilizer darts are 
ineffective as SCP-160 appears to be entirely composed of non- 
biological components, and requests to attempt a low-intensity 
electromagnetic pulse to disable it have been rejected due to 
possible unforeseen damage. 


SCP-160 was discovered by Foundation agents on / /200 following 
multiple reports of household pets from the town of [REDACTED] 
disappearing and subsequently being found dead under unusual 
circumstances. SCP-160 was quickly identified and lured into a 
transport vehicle by a containment team and subsequently taken to 
Site .A search of the area turned up over desiccated small 
animals including house cats, rabbits, wild rodents, and miniature 
dogs.

SCP-161: Pinwheel of Doom! 


All three versions of SCP-161 


Item #: SCP-161 
Object Class: Euclid 


Special Containment Procedures: All three instances of SCP-161 
are to be kept in separate containers in containment locker 34 Zeta. 
Each container is to be triple locked, with all nine keys to go to 
separate members of the Senior Staff. Once every three months, 
each individual instance of SCP-161 is to be removed from 
containment. Current scheduling allows for only one instance to be 
removed in any given month. 


When removing SCP-161, the remover is required to not be a 
member of Senior Staff; however, they are to be accompanied by 
the three members of Senior Staff with the keys, at all times that 
SCP-161 is out of containment. The remover is to be dressed ina 
full environmental suit, with extra reinforcement around the wrist 
joints, to avoid contact. The Senior Staff accompanying the remover 
are to be dressed similarly. 


Before removal, a cell is to be set up for activation of SCP-161. Two 
D-Class will need to be requisitioned. One D-Class is to be strapped 
into a chair, immobilized, their left arm at a right angle to their body. 
It is imperative that their wrist be locked in, so that they cannot turn 
their hand, or move the angle of SCP-161. The second D-class is to 
be strapped to the wall directly in front of the first D-class's hand.
