Last picture taken of SCP-XXXX. circa 1944

Item #: SCP-XXXX

Object Class: Pending Keter

Special Containment Procedures:
SCP-XXXX is currently uncontained. Several specialized Task Forces trained in armored warfare are to be placed among the tank divisions of communist countries to help counter any SCP-XXXX attack as well as containing information leaks about any apparitions of SCP-XXXX.

Description:
SCP-XXXX was a phenomenon recorded between 1944 and 1945 taking the appearance of a German tank which targeted several soviet armor divisions, inflicting heavy casualties each time. All records about SCP-XXXX mention the sudden appearance of a Tiger Porsche, later identified as the Panzerbefehlswagen Tiger (P) 003, who was deployed to Panzerjäger Abteilung 653 in April 1944. All german records of SCP-XXXX state that it was mysteriously lost in July of 1944, the wreck of the tank was never found.

When SCP-XXXX materialize to attack, it will always pick an area where it will be at an advantage, for example behind cover such as large bushes or piles of snow. After leaving, the area where SCP-XXXX materialized on will appear scorched on a 1 meter radius.

The following is an interview made in 1945 of one of the only survivors of a SCP-XXXX attack.

Interview Log

Operation Downfall was a millitary operation initiated by Soviet general Georgy Zhukov as a mean to end the increasing threat of SCP-XXXX who in only 2 months, appeared more than 1█ times and destroyed 45 tanks. The operation called for a strength of 2 soviet garrison armed with several anti-tank rocket launchers and 25 Anti-tank guns; 57 Soviet armor consisting of primarily self-propelled guns.

To force SCP-XXXX to appear, several decomissioned T-34 tanks were placed as bait in a clear field without any possibility for SCP-XXXX to ambush. 1 hour after deployment of the tanks, SCP-XXXX manifested in a large mortar hole where it immediatly started firing. SCP-XXXX was recorded being hit 107 times by various calibers, ceasing movement when a 100mm shell fired from an experimental T-34-100 hit SCP-XXXX's ammunition storage. SCP-XXXX disappeared following the explosion.

Abbendum XXXX:
Around 1992, SCP-XXXX was discovered after 47 years of inactivity by a satellite in a recently burnt forest near ██████, Ukraine. Following this, SCP-XXXX suddenly started appearing throughout Russia and in some cases Germany without displaying any hostile interactions with close-by witnesses.

In 20██, the chinese 1st Armored Brigade was suddenly attacked during a training session in B████. An estimated 15 ZTZ-99 Main Battle Tanks were destroyed or damaged. A ZTZ-99 MBT was recorded firing at the location of SCP-XXXX, SCP-XXXX withdrew 2 minutes after several hits recorded to it's hull and turret. It is unknown what caused SCP-XXXX to reappear after ██ years.

SCP-XXXX.

Item #: SCP-XXXX

Threat Level: Yellow ●

Object Class: Euclid

Special Containment Procedures:
The waters around SCP-XXXX are to be monitored at all times. Any non-authorised boat approaching SCP-XXXX are to be rerouted under the excuse of a nuclear testing area.

No vehicles using an animals name are to be introduced into SCP-XXXX unless during testing conditions.

Follwing Incident-XXXX, staff and vehicles are to be thoroughly searched before leaving SCP-XXXX for any stray SCP-XXXX-A instances.

Description:
SCP-XXXX is a land mass consisting of a variety of biomes, most commonly forests and jungles. SCP-XXXX is located in the Pacific Ocean, 15.██████°S, 243.██████°W and is approximately 105 km² in size as of 18/07/2001. SCP-XXXX possesses an invisible field that ranges up to 2km away from the shores of SCP-XXXX. This invisible field has been discovered to be the origin of the existence of SCP-XXXX-A instances. When an instance is taken out of SCP-XXXX's area of effect, it will transform back into it's original state; vice-versa if a vehicle possessing an animal name is introduced into SCP-XXXX, it will transform into an instance of SCP-XXXX-A.

SCP-XXXX is inhabited by an unknown number of vehicles displaying animalistic behaviour. These vehicles, collectively designated SCP-XXXX-A, are able to move in ways physically impossible despite their outer metallic layer. Some instances representing snakes were observed to slither and climb without any signs of stress or injury on the metallic structure. Analysis of captured SCP-XXXX-A instances revealed the presence of flesh and organs underneath their metallic outer-layer, this feature is common in all of the SCP-XXXX-A instances. This characteristic can be directly seen on vehicles displaying an open-top. DNA tests revealed that the DNA found inside the vehicles correspond to their respective animal.

Like a regular animal, SCP-XXXX-A instances need to drink, eat and sleep. Instances possessing armaments such as large-caliber high-velocity guns or coaxial machine guns were shown to use these weapons the same way the real vehicle could. Usage of these weapons were observed to only happen for either hunting (in the case of predatory animals) or self-defence. No matter the size of the SCP-XXXX-A instance, the guns were observed to cause as much damage as their counterpart. Vehicles who do not possess armaments have been seen tailgating potential prey and knocking them over. Once the vehicle is flipped or rendered incapacitated, the predatory instance will begin to eat on the prey by opening the bumper reinforcer or by there armaments. It is unknown how SCP-XXXX-A instances manage to fire or reload their weapons as no ammunation was found within captured specimens and X-ray scans

Testing showed that a vehicle placed inside SCP-XXXX takes 12 hours to transform into an instance of SCP-XXXX-A. When a SCP-XXXX-A is removed from SCP-XXXX, it will turn back into it's original vehicular state in 24 hours. Fake brand of vehicles introduced in SCP-XXXX did not become SCP-XXXX-A instances. Observations made on open-top vehicles showed that when an SCP-XXXX-A instance is reverting back to a vehicular state, the flesh and organs within the instance enters a state of rapid decay.
Fake brands of vehicles introduced in SCP-XXXX did not become SCP-XXXX-A instances. It is currently unknown how the ecosystem is still thriving despite the high diversity of species which would’ve never met normally in the wild.

Incident-XXXX:
On 23/05/1997, the FMS¹ Hammond departed from █████ toward SCP-XXXX to resupply on-site observation stations. After finishing the resupplying of Outpost-Ω, FMS Hammond left SCP-XXXX's coast. Contact with the FMS Hammond was lost apart from a couple SOS signals on foundation-specific frequencies. The crew of the FMS Hammond was promptly rescued on the following hours and were taken for questioning. Witnesses described the spontaneous appearance of gigantic vehicles which caused the FMS Hammond to sink into the depth of the ocean.

Inspection of the sunken FMS Hammond led to the discovery of 2 German Panzerkampfwagen VIII "Maus" super-heavy tanks and 1 Landkreuzer P. 1000 "Ratte" mobile fortress resting in the bottom deck of the FMS Hammond. The Ratte had ruptured the hull of the FMS Hammond. Recovered camera footage showed that several SCP-XXXX-A instances entered the cargo bay before departure.

Two instance of SCP-XXXX-A observed drinking.

Addendum: Discovery

Subject: Expedition through SCP-XXXX.

Report: On

We found a watering hole deep within the island today and were greeted with a very surprising scene. A herd of Chevrolet Impala were casually drinking around the water, we were observing the scene from a safe distance until one of the guys noticed a turret slowly approaching one of the cars. An M4 Sherman Crocodile surged out of the waters and somehow grabbed an Impala and dragged it into the water were others Crocodiles approached them. T'was a bloodshed I can tell you that, or well an oilshed if it can be called like that.

Helicopter venom is something I never thought I'd write but here we are. Thomas had found a very peculiar species, it was a very small car, but it was making a web! While Thomas was writing his notes, a Bell AH-1 Cobra helicopter slithered behind him and bit his ankle. I never thought an helicopter could bend like that to be completely honest.

While waiting for a rescue vehicle to pick up Thomas, I was looking at a valley through my binoculars and was able to catch a glimpse of a large herd, appearing to migrate. It primarily consisted of Elefant tank destroyers but I caught a glimpse of a couple Chevrolet Bisons and Ford Mustangs moving along the slow pachyderms.

Instance of SCP-XXXX-A

I went scouting alone the other day while the others stayed at the camp and stumbled upon a unique sight: Tank courtship. A Panzer VI Tiger I was siting in place while a Panzer VI Tiger II was doing circles around it, sometimes stopping to give it what appeared to be headpats. I left before they noticed me and to give them some privacy. Tank mating is weird.

I noticed a smoke eruputing from the tree-tops
Another day another set of notes. We saw an elderly Tortoise heavy assault tank getting attacked by an ambushed Jagpanther, although the Tortoise didn't even bat an eye and just ignored the big cat, the later of which just left after a while. We also found a lone Triumph Stag with several Ford Raptors perched on top of it, they seemed to be eating away at the various flies flying around them and the Stag.

A family of Volkswagen Foxes tore through our food rations that were stored in one of the bags. This single encounter managed to put an end to this expedition.

On our way to the nearest Observation station, I saw a meatball-sized tank fly in front of me. It doesn't even surprise me anymore.

Item#: SCP-XXXX

Object Class: Safe (potential Euclid)

Special Containment Procedures: All SCP-XXXX instances are currently Stored inside passcode protected safes in Warehouse D-13 at Site-17. Each passcode is to be given to Level 3 personnel or higher. SCP-XXXX instances are not to be used outside of testing.

Description: SCP-XXXX is a collective designation for a series of wooden tank toys called “Dr. Wondertainment’s War At Home Tanks Play-sets!”. The wooden tanks currently contained by the foundation are carved to look like tanks that were used during the second world war, with German tanks being the most commonly found instances of SCP-XXXX (see Addendum XXXX-1). Each tank has a small button on top of their turret which, when pressed, will cause the toy to fire a live shell out of it’s cannon despite there being no hole at the end of the cannon for the shells to come out of. Button also does not have connection to anything inside the SCP-XXXX instances. The shells the tanks fire will explode on impact, though faulty shells have been reported. Analysis of the faulty shells and the impact of said shells have shown that each instance of SCP-XXXX fires the same caliber shells as the guns of the actual tank that the SCP-XXXX instances represent.

Addendum XXXX-1:
On the 24th of January 202█, two packages were found by Foundation agents at the entrance of Site-17. The package was attributed to J█████ H███, the director of Site-17. Security cameras were unable to record who placed the packages following a malfunction at the precise time that the package was assumed to be dropped off.

Access to Level 3 Personel or higher.

SCP-XXXX

Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX is to be contained in the middle of a 52 x 52-meter chamber. Any entrances to the chamber must be fitted with a metal detector to prevent any metallic items from being brought within the effective range of SCP-XXXX.
Water sprinklers and hoses filled with seawater are to be installed on the ceiling and entrance of the chamber respectively to deal with potential SCP-XXXX-1 creations.

Description: SCP-XXXX is a black mask stylized as a Japanese menpō with signs of slight wear. The mask possesses an open mouth with bronze-colored teeth and eyebrows. It has a pair of horns, giving it the appearance of a demon. SCP-XXXX is approximately 25 centimeters tall and 15 centimeters wide. Attempting to wear SCP-XXXX will cause the individual attempting to wear it to find themselves unable to complete the task of putting on the mask, regardless of whether they want to or not.

SCP-XXXX is constantly experiencing a phenomenon observed to be extreme magnetism. It possesses a magnetic pull in all directions horizontally, reaching as far as 50 meters. Testing has shown that SCP-XXXX’s magnetism will only attract items that are at least 60% composed of iron. When SCP-XXXX attracts an iron object, it’ll always attach itself to SCP-XXXX behind the mask, regardless of which direction they were originally pulled from. This is observed as an orbital effect whenever the item comes from 180° in front of SCP-XXXX, ending behind SCP-XXXX on all occasions.

After enough metal has accumulated behind SCP-XXXX, it will begin to meld and merge together to form a shape resembling a large humanoid, designated SCP-XXXX-1. When SCP-XXXX-1 is first formed, it will remain inactive, only reacting to basic outside stimuli. During this time, SCP-XXXX’s magnetism effect is still active, with objects drawn closer performing their orbit into SCP-XXXX-1’s back. Once a certain mass of metal is obtained, SCP-XXXX's magnetic effect will cease and SCP-XXXX-1 will begin to move around. Upon this occurring, SCP-XXXX-1 will rip out a part of its back to create a weapon resembling a Japanese kanabō. SCP-XXXX-1 will then become highly aggressive.

Despite its rather large body structure, SCP-XXXX-1 was recorded to be relatively fast, achieving speeds up to 50 km/h. SCP-XXXX-1’s iron composure makes it bulletproof. The only way SCP-XXXX-1 takes noticeable damage at a fast enough rate to stop it is through applying seawater to accelerate rusting.

Staff of SCP-XXXX - circa 1945

Item #: SCP-XXXX

Threat Level: Yellow ●

Object Class: Euclid

Special Containment Procedures:
A copy of SCP-XXXX was built in 1955 to accomodate for public knowledge of Project Riese, located ██ km away from the actual position of SCP-XXXX.

Site-105 is built around the entrance of SCP-XXXX and is currently set up under the guise of a lumberjack company. Chamber 04 is to remain locked down at all times, several guard posts armed with anti-tank weaponery are to be placed at the end of a specially built corridor designed to slow down possible escapees.

Description:
SCP-XXXX is a factory located in Lower Silesia, Poland. SCP-XXXX was built around 1945 by Nazi Germany. SCP-XXXX consist of 7 underground structures and several hidden chambers accessible through doorways in various locations throughout SCP-XXXX.

SCP-XXXX-α is an anomalous phenomenon where once a year on the ██th of January, several human like figures, designated SCP-XXXX-1, wearing contemporary german uniforms will begin to appear throughout SCP-XXXX. SCP-XXXX-α will last for 4 days until which SCP-XXXX-1 will begin to panic and run in various directions. Personnel present near SCP-XXXX-1 during the end of SCP-XXXX-α will hear what appears to be plane engines overhead followed by screaming and explosions, after the explosions all SCP-XXXX-1 instances will disappear abruptly. During the duration of SCP-XXXX-α, SCP-XXXX-1 will operate the various machineries within SCP-XXXX and creates multiple objects ranging from contemporary german weapons and vehicles to objects with anomalous properties. All objects created during SCP-XXXX-α remain even after the end of the cycle.

Recorded items:

Chamber	Items	Notes
Chamber 01 - Wunderwaffe Project	Karabiner 98kurz	Item was noted to be able to load any type of ammunation and subsquently fire it with the drawback of high recoil depending on the ammunation used.
Chamber 02 - Biological department	Unidentified viral agent	Item is capable of enhancing regular human subjects with the drawback of necrosis and lessened brain functions.
Chamber 07 - Weapon manufacturing	Fallschirmjägergewehr 42 (FG-42)	No changes.
Chamber 03 - Living Quarters and Kennel	Large canis lupus familiaris	Entities resemble German Shepherds with advanced necrosis appearing throughout the body. Entities have been noted to be aggressive.
Chamber 04 - Vehicle Research and Development department	Unidentified tank	Vehicle is a mixture of several late-war tank parts, primarily the hull of a Panzerkampfwagen V Panther; the turret and canon of a Panzerkampfwagen VIII Maus and the tracks of a Panzerkampfwagen VI Tiger
Chamber 07 - Weapon manufacturing	Canisters containing an unknown gaz	Testing showed the gaz is highly corrosive and capable of movement. It has been noted that the gaz bases its movement on heat signature.
Chamber 01 - Wunderwaffe Project	Electrical gun	Item is capable of shooting a chained electrical current with an intensity of 200 000 amperes. It is powered by an unknown material ressembling iron and carbon.
Chamber 04 - Vehicle Research and Development department	Sd.Kfz. 234/5 « Hornisse »	Vehicle ressembles a Sd.Kfz. 234/2 « Puma » mounted with a 88 millimeter gun usually found on Pak 43 anti-tank guns. The drawing of a stylized Vespula germanica² is located on the right side of the vehicle's hull.

Item built during SCP-XXXX-α

Addendum accident-XXXX:
On 01/██/1987, following a recent SCP-XXXX-α cycle, several noises were heard from within Chamber 04. After inspection it was discovered that the origin of these noises were from a tank built during the previous SCP-XXXX-α cycle. This tank was later identified as a ressembling blueprints created for a potential Panzerkampfwagen VIII Maus and Sturmpanzer IV Brummbär. Several screams were heard emanating from within the vehicles following one of the guards lightly tapping the hull of the Brummbär, after which the tank's engines activated and the turrets opened fire on the personnel present in the room, resulting in 7 casualties.

Despite appearing as if autonomous, it was discovered that a total of 11³ black ghost-like figures were manning the two tanks. The vehicles do not seem to require either fuel or additional ammunation.

Item #: SCP-4307

Threat Level: Yellow ●

Object Class: Euclid

Special Containment Procedures:
SCP-4307 instances are kept in a reinforced aquatic containment chamber filled with water treated to replicate the Barents Sea. One side of each chamber wall is to be coated with a lead plating, and X-ray emitters are to be installed in 2 corners of the chamber with the purpose of being activated once a week to feed the SCP-4307 colony. Vegetation inside the chamber is to be maintained once every three weeks by Class-D personnel equipped with reinforced diving suits.

Description:
SCP-4307 is the designation for a group of 27 entities belonging to the extinct Nothosaurus genus⁴. The organisms are 4m long on average, although some specimens have been recorded reaching 5m to 7m in length. SCP-4307 specimens feed off of common sea life, primarily consuming fish. However, specimens have been observed hunting larger prey, including animals larger than themselves.

SCP-4307 specimens are capable of emitting electromagnetic pulses through an organ located near the brain. Composition of this organ includes a high concentration of electrocytes. The pulses are primarily used to incapacitate possible predators but are additionally capable of temporarily deactivating electrical devices. SCP-4307 instances were observed 'feeding' on radiation from the sunken K-278 Komsomolets during the initial recovery of SCP-4307. Testing indicated that depending on the type and amount of radiation absorbed, the intensity and type of electromagnetic pulses changes (See SCP-4307 Radiation testing). How SCP-4307 is able to survive these pulses and close proximity to radiation without any repercussions is unknown. SCP-4307's Triassic ancestors seemingly developed this organ to counter the sudden appearance of sharks, the electrical discharges being weak enough to disrupt a shark's senses, stunning it.

SCP-4307 instances do not perceive humans as a source of food and will generally ignore them, although several cases of playful interactions have been noted. However, SCP-4307 instances have been known to lash out using their jaws if feeling threatened.

It is unknown how SCP-4307 managed to survive to our time period as no further fossils of nothosauridaes were found following the Triassic period. Foundation palaeozoologists suggest the possibility of the SCP-4307 colony becoming frozen in a secluded ice cave near the end of the Triassic period, somehow managing to survive through multiple extinction events.

Addendum 4307.1:
SCP-4307 was discovered in May of 1989 following reports from the Foundation's Russian-branch signaling the sudden disappearance of the K-278 Komsomolets⁵ in the Barents Sea. Two other submarines are believed to have been sunk by SCP-4307 instances, K-129 Minerve and the USS Scorpion both during the 1960s. It is currently theorized that the SCP-4307 instances were attempting to feed on radiation from their nuclear reactors. Foundation personnel theorize that the sudden flaring of high energy radiation caused by nuclear bomb tests in 1945 awoke a colony of SCP-4307 that had been dormant for centuries. The colony then made its way to the Barents Sea where it was subsequently discovered.

+ SCP-4307 Radiation testing

- Level 3 Access Authorised

Experiment Log 4307 - 1
Radiation: Ultraviolet

Test Subject: SCP-4307-8

Test Record:
SCP-4307-8 was introduced into the testing chamber and subsequently exposed to a high concentration of UVA radiation through 2 blacklights. After 45 minutes, SCP-4307-8 started to display bioluminescence around the head and neck. A school of fish was then released into the testing chamber. Upon SCP-4307-8 taking notice of their presence, it began charging up a pulse. Upon release, the pulse manifested as a blue ray, fatally electrocuting fish in contact with it. Testing ended after 20 minutes of SCP-4307-8 repeating this behavior.

Notes:
After being removed from the testing chamber, SCP-4307-8 lost its bioluminescence after 2 days.

Experiment Log 4307 - 2
Radiation: X-ray Radiation

Test Subject: SCP-4307-21

Test Record:
SCP-4307-21 was introduced into the testing chamber. Shortly after, it was exposed to X-ray radiation. After an hour of exposure, SCP-4307-21's skin became translucent with the organ located on the head glowing, akin to a Melanocetus johnsonii (Humpback anglerfish). A school of fish was then released into the testing chamber. Once noticed by SCP-4307-21, the specimen released a pulse which could not be detected visually. After five minutes, fish that were hit by the pulse turned translucent and stopped moving. A fish was captured for analysis while the rest were eaten by SCP-4307-21. The test was ended approximately 10 minutes later.

Notes:
Analysis of the fish showed that the part of the brain that controls the locomotive functions of the fish was damaged, rendering the fish unable to move.
SCP-4307-21 lost its translucence shortly after being removed from the testing chamber.

Experiment Log 4307 - 3
Radiation: Gamma (γ)

Test Subject: SCP-4307-15

Test Record:
SCP-4307-15 was introduced into the testing chamber and subsequently exposed to a small concentration of Gamma (γ) radiation. After 30 minutes had passed, readings showed that all radiation was absent from the chamber. A school of fish was then released into the testing chamber with the goal of triggering a pulse from SCP-4307-15, as had been demonstrated in previous tests. This resulted in a small scale nuclear blast (later identified as an amplified nuclear electromagnetic pulse), irradiating or destroying everything within a 50-meter radius. In addition, the explosion killed around ██ staff members and irradiated many others who were caught in the radius.
SCP-4307-15's remains were found lacking its head and most of the neck as a result of its proximity to the explosion.

Notes:
Testing has been suspended following the incident with SCP-4307-15. The effects resulting from exposing specimens to radiation are too unpredictable, and quite frankly, further testing isn't worth the risk of losing more instances or personnel. O5-██

Addendum Journal 4307:
Evgeny Vanin, commanding officer of the K-278 Komsomolets at the time, held a logbook during the lifetime of the submarine. A few entries preceding the sinking of the K-278 Komsomolets were written. Relevant and/or noteworthy excerpts have been translated from Russian and transcribed for analysis:

Page 350

30/03/1989
As per orders of the Motherland, we went to patrol around Norway on a lookout for any American submarines. We arrived in the Norwegian Sea at around 0200 and have been patrolling since.

Page 353

02/04/1989
We've been roaming the Norwegian Sea and it's surrounding areas for 3 days now. Radar operator caught a large signal encircling the submarine at around 2200. I dismissed it as predatorial sea life mistaking us for a dead whale.

Page 356

05/04/1989
Something's attacked us. All electronics are out and we cannot reach the Motherland through our radios. The motors also refuse to start back up. How those damn things destroyed our equipment without direct contact is unbeknown to me. The crew is panicking but I don't blame them, they are young, they are afraid of death. If the mechanics somehow manage to restore our communications I'll send an SOS to our leaders requesting immediate help.

Page 358, Final entry

07/04/1989
At around 1500, communications were restored after 2 days of darkness and living on rations. The commander managed to send an SOS before what appeared to be an electric shock fried our electronics yet again. At 2000, strange sounds were heard from the outside, ramming into the ship. A fire broke out in the ensuing panic and the commander was wounded. After recovering the logbook I and several other crewmen went for the single lifepod. It was utter chaos, men were fighting each other to obtain a spot. I managed to slip by the crowd and reach the lifepod, and we departed shortly after due to the fire spreading rapidly. When we ejected, I saw a glimpse of those…creatures. They looked like reptiles but something about them was off, something that I can't explain. Two hours after we reached the surface, a Russian boat that heard our SOS arrived and took us aboard. End of Log

Abbendum 4307.2:

An image accompanies the last entry of the logbook, presumed to have been made by its author.

SCP-4191 and SCP-4191-ẟ

Item #: SCP-4191

Threat Level: Orange ●

Object Class: Euclid

Special Containment Procedures:
SCP-4191 is to be contained in a standard steel containment cell lined with Titanium. Food will be automatically dispensed once per day. Any leftover meat will be retrieved by 1 Class-D personnel wearing a fire-retardant suit.

A small number of flammable materials (usually pieces of wood) are to be introduced twice a week to fill SCP-4191's needs. Aside from the regulated introduction of wood, no flammable materials are to be introduced within the chamber at all time.

Description:
SCP-4191 is a Komodo Dragon (Varanus komodoensis) suffering from pyromania. SCP-4191 wears a papier mâché outfit made to resemble a common western dragon, designated SCP-4191-ẟ. SCP-4191 is capable of generating fire through SCP-4191-ẟ by self-immolation - both SCP-4191 and SCP-4191-ẟ are completely immune to the fire generated by the outfit. Removing SCP-4191-ẟ from SCP-4191 is possible, although if separated for a long time, SCP-4191 will become agitated. Analysis of SCP-4191-ẟ shows that it secretes a liquid with a glue like consistence; this liquid is highly flamable. Its unknown how SCP-4191 manages to light up the substance.

Testing has revealed that SCP-4191 is an infertile young adult male. Despite SCP-4191's pyromanic nature, it is rather friendly and cooperative with Foundation personnel, happily playing (and subsequently incinerating) various toys given. SCP-4191 has been affectionately nicknamed by the staff of Site ██ assigned to it as "Pyro"⁶.

SCP-4191 was first discovered by foundation agents following reports of multiple fires breaking out in the small village of S██████, France. After 4 days of tracking down the anomaly, SCP-4191 was intercepted and restrained by agents a few minutes after burning down an abandoned barn in a nearby village.

Addendum SCP-4191 - 01/07/██15:
Over the years of SCP-4191's containment, staff noticed that SCP-4191 started slowly eating less and less, becoming thinner almost to the point of the ribcage's outline showing on the side of SCP-4191. Foundation personnel trying to interact with SCP-4191 resulted in the subject being uninterested, simply walking away.

The following is a conversation recorded of Researcher Wasp and Senior Researcher Avalon on the foundation's intranet service:

R_Wasp: hey ████

SR_Avalon: What, what is it

R_Wasp: we got an issue with 4191, it hasn't eaten for 3 days now

SR_Avalon: Are you sure ?

R_Wasp: yeah, we tried to force-feed it but it just spat out the food like it was junk

SR_Avalon: Strange

SR_Avalon: Did you ask ███ if he could help ?

R_Wasp: nah I haven't, i heard he was busy with SCP-████. But it is worth a shot

[10 minutes later]

SR_Avalon: So any news

R_Wasp: Yeah i asked him if he was free and he said yes. Lemme add him to the chat

Z_Sparks has been added to the channel

Z_Sparks: Yo, so what's this problem you told me about

SR_Avalon: One of the SCPs we are assigned to is slowly starving to death, we can't find the reason why

R_Wasp: Hey and yeah that's pretty much it, it's 4191 in case

Z_Sparks: mmh, did anything happen that could have traumatised it ?

R_Wasp: nah we checked with all the personnel assigned to it and camera footage, everything is normal

SR_Avalon: Apparently from what Wasp told me it doesn't even want to interact with the researchers despite being a relatively social animal.

Z_Sparks: I may have an idea, does it interact with other member of its species ?

R_Wasp: it's an unique individual so sadly no

Z_Sparks: There's your problem. It being unable to interact with another of its species made him lonely to the point of becoming depressed.

SR_Avalon: I see where this is going, let me go talk to the superiors for the test approval and we'll proceed

R_Wasp: Hella.

Diagnosing this as a severe depression most likely caused by SCP-4191's lone status, Foundation Zoologist Sparks suggested the idea of introducing a Varanus komodoensis to SCP-4191, hoping that they would bond and cause SCP-4191 to cease its starvation.

Experiment Log 4191 - 1
Date: 01/10/██15

Purpose of the test: Preventing SCP-4191 from starving to death by introducing him to one of his kind.

Test Result: A young female Komodo dragon was introduced to the chamber. After 5 minutes, SCP-4191 started moving toward the female at a slow pace until fully facing the subject. The two sniffed each other for around 2 minutes and appeared to begin playing. 30 minutes after the beginning of the test, SCP-4191 suddenly lit itself up while the female was on top of him. Due to the sudden heat, the subject quickly went to hide in one of the corners of the chamber. SCP-4191 appeared distraught and tried to approach to no avail. Test ended after 5 minutes of the incident.
After the test, the female was treated for first degree burns to the stomach and legs and was donated to a Zoo in the city of ████, France soon after.

Z_Sparks: So how did it go

SR_Avalon: It was a disaster.

Z_Sparks: How come

R_Wasp: he injured the komodo he met by accident. So now we have a depressed AND distressed entity

Z_Sparks: So wait, after reading the entry it says that it can burn thing right ?

SR_Avalon: Yeah pretty much

Z_Sparks: I remember reading a report about fire breathing varans captured by the French division.

R_Wasp: wait, are you suggesting we could crosstest the two ? What if these dragons attack 4191

SR_Avalon: It's our best solution, otherwise we'll have a neutralized SCP on our hands

Z_Sparks: ^

R_Wasp: true, although who shall we contact to get a hold of one of those ?

SR_Avalon: Apparently a researcher named Grym is responsible of them, i'll contact him.

Z_Sparks: Make sure to tell him its important for the survival of the SCP

SR_Avalon: yeah, yeah, let me handle it.

Addendum SCP-4191 - 01/16/██15:
It was decided to introduce SCP-4191 to SCP-124-FR that were discovered in Australia by the French branch of the Foundation in 06/17/██12. SCP-124-FR demonstrated a near immunity to fire and high temperatures. Senior Researcher Avalon requested Site Aleph to ship 2 SCP-124-FR instances to Site ██ for testing.

Experiment Log 4191 - 2
Date: 01/10/██15

Purpose of the test: Preventing SCP-4191 from starving to death by introducing it to a pair of SCP-124-FR instances.

Test Result: Both instances of SCP-124-FR were introduced. SCP-4191 immediately fled into the corner of its chamber and stayed there while the pair of SCP-124-FR began to explore the chamber. This lasted for 5 minutes until one instance of SCP-124-FR saw SCP-4191 moving toward it at a slow pace. Pausing every few seconds to stick its tongue out, until it was a meter away from SCP-4191, the pair stood motionless staring at each other. When SCP-124-FR approached SCP-4191 and began to sniff its neck, SCP-4191 immediately lit up on contact. SCP-124-FR backed up in shock, staring at SCP-4191 for a minute before advancing forwards and rubbing its head on SCP-4191 neck. It then turned and walked towards the other instance of SCP-124-FR. SCP-4191 tilted its head then followed SCP-124-FR. The other instance of SCP-124-FR sniffed SCP-4191 and began to rub its head on SCP-4191 shoulder. This grooming ritual lasted for 5 minutes before all three instances laid down with one instance of SCP-124-FR laying on either side of SCP-4191.

Following the test with the SCP-124-FRs, SCP-4191 was allowed to routinely meet with the pair, slowly regaining weight after regaining an appetite. After SCP-4191's recovery, its containment procedures were rewritten (leading up to revision REVISION 4191 - 2). A small colony of SCP-124-FR were imported from Site Aleph to Site ██ to be housed with SCP-4191.
After initial introduction of SCP-4191 to the SCP-124-FR colony, SCP-4191 was accepted into the colony by the matriarch of the group.

SCP-4178

Item #: SCP-4178

Threat Level: Yellow ●

Object Class: Euclid

Special Containment Procedures:
As of recorded date 09/01/1998, all 19 retrieved instances of SCP-4178 (-1 to -19 respectively) are to be contained in vivariums no less than 10 m x 20 m, with small pools of water and a sandy substrate as interior. Male and female instances are to be contained separately to prevent further mating and the possible death of male instances. SCP-4178 specimens are to be only taken out of their vivarium's for testing purposes. SCP-4178-20 is kept in a standard containment locker with an internal temperature of -1°C.

Every 2 weeks, no less than 2 Class-D personnel equipped with reinforced apiarist's suit are to be sent in the chamber to clean and collect any unnecessary webbing produced by the organisms. This behaviour is theorised to prevent web from building up in the abdomen of the instances and thus is considered normal. Any eggs located during cleaning sessions are to be immediately collected and stored in a well-lit freezer with an internal temperature that does not exceed 2º C.

Description:
SCP-4178 are a species of carnivorous arachnids ressembling members of the Araneidae⁷ family. SCP-4178 possess the abdomen and wings of a Vespula germanica⁸. Analysis showed that the species of SCP-4178 is one of the largest flying arthropod to have existed, second to Meganeura moniy. SCP-4178 specimens have been shown to be able to produce venom in both the stinger and the fangs. Analysis has shown that the venom located in the stinger is much more potent than the venom in the fangs. It has been noted that female members of the species are significantly larger than the males, a common trait seen in regular spider and most wasp species. Male and female individuals have not shown any other sexual dimorphism.

Instances of SCP-4178 were discovered in the cave of an abandoned village located in Spain, housing a colony of specimens comprising of around 50 individuals. A large hive was recovered along with 20 instances. The rest of the colony was killed during the recovery. Other colonies were discovered in the surrounding area and were subsequently eliminated. A cover scenario was created following the operation.

DNA tests have shown that the SCP-4178 specimens possess a unique kind of DNA. No traces of Vespidae DNA have been found.
SCP-4178 will leave a stung victim in a state of complete paralysis, followed by an anaphylactic shock after a few minutes. Soon afterwards, multiple instances of SCP-4178 will approach the paralysed prey and will begin secreting a paste-like webbing from their spinneret glands located at the tip of their abdomen under the stinger and will start wrapping the prey with it. This process tends to take up to 40 minutes for humans; larger prey can take up to an hour to be fully covered by the webbing. Solidification of the cocoon usually takes up to 15 minutes. After solidifying, the web takes the appearance of a wasp nest.

SCP-4178's species can be traced back to 240 million years ago in the middle of the Triassic period through fossil record. These ancestors didn't possess wings, unlike their modern relatives. Fossils found in █████ in the northern parts of Spain as well as near Santarem, Brazil, shows that these organisms built trapdoors in the floor using the paste-like silk. The first known fossil found with wing markings dates from 140 million years ago, during the late Jurassic era.

Experiment Log 4178 - 1
Date: 02/10/20██

Purpose of the test: Research SCP-4178's behavior in the presence of a pompilid wasp.

Test Subject: Pompilidae pepsis (Tarantula Hawk wasp)

Test Result: Seven female instances of SCP-4178 were placed into the testing chamber. Once the SCP-4178 instances settled, ten Pompilidae pepsis were added to the testing chamber. Despite SCP-4178 size dwarfing Pompilidae pepsis, all SCP-4178s approached them with caution, keeping their distance. After approximately thirty seven minutes since testing began every SCP-4178 instance cornered themselves in the bottom left corner of the testing chamber, showing signs of being distressed and aggravated. Twenty four minutes later testing was discontinued as instances continued to be in this state for the remaining time. Test was repeated on male instances of SCP-4178 with the same result.

Note: While this may be instinctual behaviour from SCP-4178, it could also be a sign of an expected intelligence level. Further testing with other species has been accepted to expand this theory.

Experiment Log 4178 - 2
Date: 02/16/20██

Purpose of the test: Research SCP-4178's behavior in the presence of another large Arachnid.

Test Subject: Theraphosa blondi (Goliath birdeater tarantula)

Test Result: 3 SCP-4178 instances were placed into the testing chamber before a single Theraphosa blondi was brought in. Once the Theraphosa blondi was placed into the chamber all SCP-4178 instances ignored it, carrying on with their usual activity. Testing finished after 3 hours with no added result.

Note: Compared to the test with the Pompilidae pepsis, this was an unexpected result. It has been requested that the Tarantula Hawk wasp test would be repeated but with a longer time duration than before.

Experiment Log 4178 - 3
Date: 02/19/20██

Purpose of the test: Research SCP-4178's behavior in the presence of a pompilid wasp for a longer duration.

Test Subject: Pompilidae pepsis (Tarantula Hawk wasp)

Test Result: Test began with the same layout as Experiment log 4178 - 1. As expected the SCP-4178 instances repeated the same behaviour as the previous Pompilidae pepsis experiment, placing themselves in the bottom left cornor of the chamber. After approximately 4 and half hours of this behaviour, one Pompilidae pepsis attacked one SCP-4178, stressing the instances and causing it to fly out of the corner. The instance that was attacked fell and the Pompilidae pepsis advanced onto the SCP-4178, paralyzing the instance. Another SCP-4178 instance flew out of the corner and eliminated the attacking Pompilidae pepsis. All other SCP-4178s joined it and attacked the remaining Pompilidae pepsis. The paralysed instance was recovered and monitored, analysis showed that the immunity system of the instance quickly rid the body of the Pompilidae's venom.

Note: This test brought us an interesting fact. SCP-4178's immunity system appears to be extremely resilient to venom compared to other arthropod and even humans. Further analysis of the biology of SCP-4178 should be made as soon as possible. - Researcher W███

Experiment Log 4178 - 4
Date: 02/24/20██

Purpose of the test: Research whether SCP-4178 specimens can tell the difference between an inanimate object and a living being.

Test Subject: Plastic mannequin representing a young woman, commonly used in clothing display.

Test Result: Mannequin was placed in the center of the chamber. SCP-4178 specimen introduced in the room after approximatly 2 minutes. SCP-4178 initiated flight and searched the chamber for 5 minutes before rapidly moving towards the mannequin. SCP-4178 started biting and stinging the mannequin but soon stopped. SCP-4178 proceeded to what appeared to be sensing the mannequin with its stinger. Test ended after SCP-4178 resumed roaming the room for 10 minutes.

Note: Despite initially showing sign of aggressiveness toward the mannequin, the reaction of SCP-4178 after discovering the prey was not a living being shows a degree of intelligence not shown in most arthropods. It also seems that SCP-4178's species naturally sees humans as prey, this is deducted by observing SCP-4178's reaction upon locating the mannequin during flight and landing.

Experiment Log 4178 - 5
Date: 03/02/20██

Purpose of the test: Research SCP-4178's behavior toward its ancestor.

Test Subject: Ancestor of SCP-4178's species recovered from SCP-646, labeled SCP-4178-Ω

Test Result: Female instance (designated SCP-4178-14) is introduced to the test chamber. After 5 minutes, SCP-4178-Ω is introduced to the chamber. SCP-4178-Ω is observed drumming for 25 seconds, SCP-4178-14 is soon afterwards observed to start shaking, after which, SCP-4178-Ω started moving toward SCP-4178-14 at a slow pace until fully facing SCP-4178-14's rear SCP-4178-Ω procceeded to rub his pedipalps on SCP-4178-14 then quickly retreated to a corner of the room; Test ended after 10 minutes of no further movements of the instances. SCP-4178-14 was retrieved and put in a vivarium until she layed an eggsac. The eggsac was quickly recovered. Analysis indicated that all the eggs were infertile. SCP-4178-14 was restored in the female vivarium shortly after.

Note: Soon after the test ended, SCP-4178-Ω was placed in the male vivarium and appears to have been accepted by the other instances. It appears that SCP-4178-Ω's species used to use both pedipalps to prevent sperm competition between males.

Experiment Log 4178 - 6
Date: 03/07/20██

Purpose of the test: Study SCP-4178's behavior toward another large flying arthropod.
Test Subject: Meganeura brongniarti recovered from SCP-3057

Test Result: 4 SCP-4178 instances were introduced into the testing chamber before a lone Meganeura brongniarti was brought in. Once the Meganeura brongniarti was placed into the chamber all SCP-4178 instances ignored it, carrying on with their usual activity. After 15 minutes, the Meganeura charged onto a lone instance (later identified as SCP-4178-20), latching on the back of SCP-4178-20 and proceeding to tear off the wings and abdomen of SCP-4178-20, incapacitating it. The 3 remaining instances soon noticed what happened and started to attack the Meganeura brongniarti. Subject soon fell to the floor of the chamber, the twitching of the wings indicated it was still alive at the time. The largest of the SCP-4178 present during the test advanced toward the Meganeura and proceed to remove the head with the use of its fangs. The instances got around SCP-4178-20 and started encasing it in web. After 1 hour of no additional results, the test was ended. The remains of SCP-4178-20 were recovered and stored in a temporary freezer.

Note: Unlike regular insects, it appears that SCP-4178's species is capable of feeling sorrow as well as anger when witnessing the death of a member of its species.

Additional Note: Testing has been suspended following the loss of SCP-4178-20. The reaction of the Meganeura and the death of SCP-4178-20 were not planned and we don't want to lose any more of the remaining instances. O5-██

Addendum 4178.1: Expedition Log
In 19██, an expedition was sent to investigate a rumor mentioning "the children of the spider goddess" in a secluded region of Brazil was initiated. After several days of searching the surroundings, a hidden precolombian temple was found, supposedly built by an unknown precolombian tribe.

An immediate query sent from commanding officer Researcher W███ demanded two Class-D personnel from Site-███ on immediate transfer, two standard exploration field kits, two wireless headsets capable of recording / transmitting audio – all requests were accepted.

The following video transcript was filmed during the first exploration attempt on the 19th of May 19██. Camera wearers were D-22371 and D-3435.

[BEGIN LOG]

Background audio is heard, voice identified as Researcher W███ briefing Class-D’s before entry

Head-mounted video viewing becomes active, no anomalous surroundings are noted at this time

Footage shows subject D-22371 entering the tomb with moderate hesitation stating that “I don’t deal with this voodoo shit.” – Subject was promised extra free-time privileges when relocated back to Site-██ if expedition was conducted – compromise was agreed upon without hesitation and subject enters overhanging doorway to the temple

D-3435 enters following behind

//Connection between Command (Dr. J████ W███) and Class-D’s recording equipment are established – exploration begins //

Command: Last microphone and video check before you go in any further, I want you both to wave your hands in front of the cameras and slowly countdown from 10 to 1 in sync, you got that?

D-3435: Alright Doc.

Both D-3435 and D-22371 complete the task, no technical discrepancies noted and subjects are clear for further entry

Command: Begin to descend deeper into the temple entrance.

After advancing within the temple for a few minutes, connection was lost with Command

Command: Yo-[static] Nearing a chamb-[static]

D-22371: Doc? You there? Great we lost coms with the surface.

D-3435: Eh who cares. They said we just have to go in and out, shouldn't take long.

D-22371: True, let's continue then. You first.

After 10 minutes of walking, D-3435 and D-22371 spot an archway with an opening filled with valuable items in the distance. A hallway and one flight of stairs is all that is between them and the items

D-22371: Holy shit! Is that a fuckin' treasure room?

D-3435: Judging by the large stacks of gold I'd say yes.

D-22371 is seen running towards the entrance

D-3435: Wait!

D-22371 suddenly stops and turns slowly and looks at D-3435. Both stop and face each other

D-22371: Listen here, I'm just trying to have a bit of fun. I've finally got the chance to do something, so I'm gonna make this worthwhile.

D-3435: Yeah, well I just don't trust a temple built centuries ago. It could be falling apart or have like snakes - venomous large snakes - with giant ass fangs an-

D-22371: Stop being so fucking paranoid (sighs).

D-3435: Why were we sent in here? Don't you think they could go themselves?

D-22371: Because they know we are fit for the job.

D-3435: (sigh) Forget about it.

D-3435 begins to walk alongside D-22371

D-22371: Do you think we'd be able to keep some of the stuff we find?

D-3435: I'd imagine not.

They begin to walk down the stairs

D-22371: Meh, I'll take some anyway, I'm sure no one is gonna notice. Besides it's not like they will-

D-22371 trips on something sticking out of the corner and falls near the bottom of the stairwell while letting out a scream

D-3435: Fuck! Are you alright? What the hell happened?

D-22371: Ah ya bandit! Something touched me.

D-22371 gets up slowly

D-22371: This place is a wreck! I think I hurt my ankle.

D-3435 checks at what caused him to trip

D-3435: What on Earth is that?

D-22371 grabs his ankle

D-22371: What is what?

D-3435 gasps

D-22371: What!

D-3435: I think… I think you tripped on a corpse.

D-22371: Really mate? Its an ancient tomb. Of course there are bodies.

D-3435: No… I mean it looks kind of fresh.

D-22371: Huh. Why don't you go check.

D-3435 cautiously returns up the stairs

D-3435: Dude there are like two bodies, they still have skin. Ugh, this is disgusting.

D-22371: Hmm… I wonder what causes that… Is this place cursed or some shit?

D-3435 goes back down quickly

D-3435: You think you can walk?

D-22371: Yeah, I'll be okay. Let's continue, I hate this place so goddamn much.

D-3435: By the way.. I'm gonna guess considering the next room is a treasury, that this place has a ton of traps.

D-22371: Yeah you're probably right, I don't want to finish like the two rotting guys up there.

After walking down 25 steps, cameras show meticulously drawn symbols into the temple walls – these engravings show men praying, inside a cave, around an altar with a large, paramount being forcing spiders out of its mouth and eyes, the floating above it. Analysis of these carvings have presented themselves as the prophesied “Arachnid Goddess” – a tribal religious deity heavily worshiped under the act of human sacrifice. Retrieved dated sacred texts have described the goddess as “our mother in skin, in bones and sky, as the one who guides us with the blood path to fortune and we give the baby with sin to her in sting, feast and rape, so we do not suffer the burden of cruel numen”. D-22371 appears distressed although both still walk in silence for approximately 3 minutes before stopping..

D-3435: What the hell is that supposed to be?

D-22371’s video footage appears to show another carving depicting two people dressed in monk-like attire, apart from the robe being ripped in multiple places on both subjects, gifting a new born child - inside a basket - to the Goddess at the altar.

D-22371: Beats me, was never a religious man myself, could never understand any of it, this just proves my case.

D-3435: Doesn’t this kinda’ stuff freak you out? I mean just look at what it’s doing to that poor kid.

D-22371: Come on man, I don’t want to be down here for long either, just man up and continue.

Seen via D-22371’s video feed, D-3435 appears to be notably shaken – sweating profusely and looking apprehensive. After 2 minutes D-3435 agrees to proceed and is then seen walking alongside D-22371 with his hand on the wall. After five minutes of walking through the temple a dead end can be seen in the distant footage, D-3435 stops before they can reach it.

D-3435: Hey I think I got somethin' here.

D-22371: What is it? We're practically at the end so we can piss off back to the start and get out of this place.

D-3435 begins to push on a part of the wall, which starts to open, revealing a hidden room with two buttons with a design of a wasp and a spider respectively

D-22371: Christ, this place just gets bigger and bigger, doesn't it?

D-3435: Well, I don't wanna find out what's inside so you may take the lead.

D-22371 is seen walking towards the buttons, presumably to inspect them

D-22371: Ha, you scared of some spiders?

D-3435 aggressively shakes his head which leads to D-22371 entering first and D-3435 following him soon after into the hidden room.

D-22371: We have some more buttons over here, I'm tempted to press em' but I think this whole place will go temple of doom on us.

D-3435: That scientist guy told us to check everything so start pressing them, this place looks old so maybe it won't do anything and we get to go home.

D-22371 seems to hesitate but then presses the two buttons. After a couple seconds of pressing the buttons a piece of the wall moves out of the way to reveal a secret chamber and a light mist arriving at the shins leaks from the chamber

D-3435: What the hell?

D-22371: Alright, uh let's just tell those scientists back there that this was all we foun-

D-22371 stops midsentence and the camera reveals that there is a mumified corpse wearing a jewel around their neck. D-22371 is then seen to slowly wander in

D-3435: Dude what are you doing?!

D-22371: I see somethin' here!

As D-22371 gets closer to the corpse the mist begins to lower and starts to reveal a dead instance of SCP-4178 in a curled up position. D-3435 soon notices the dead instance and begins to step away from the entrance

D-3435: Oh fuck what is that! Dude I need your fucking help!

D-22371 successfully approaches the mumified corpse and takes the jewel only to turn around and see the half buried instance of SCP-4178 in the mist

D-22371: Wow what the fuck is that! [pauses] Wait, I think it's dead.

D-3435 is seen standing by the wall trying to gain some distance from the dead instance

D-3435: Oh yeah? what's make you think that sherlock.

D-22371: Look at how its leg are curled up, its dead. I used to keep spiders before being sent to jail, I know the body language of the thin-

D-3435: What?!

D-22371: Dude I get you are scared of spiders and all but come see this shit, the damn thing has wings, and a big ass body! Almost like a hornet!

D-3435: Great, flying fucking spiders. Let's go back to the surface, I'm not spending anymore time in this hell hole.

[END LOG]

After 1 hour and 34 minutes, D-22371 and D-3435 successfully came back to the surface. Analysis of the sacrificial chamber showed that approximately 12 bodies of SCP-4178 were found as well as 36 cocoons found all throughout the temple. Live eggs were found in another hidden chamber within the temple, they seemed to be kept in a sort of stasis by the temperature of the room ranging around 5°C. It is unknown how the tribe managed to keep the room at this temperature.

Addendum:
Following the exploration, it was theorised that the temple was built around 1000 year ago. It appears that the temple was a tribute to the Mayan gods Ah-Muzen-Cab and the Great Goddess of Teotihuacan.

Item #: SCP-4169

Threat Level: Green ●

Object Class: Euclid

Special Containment Procedures:
At this time, SCP-4169 is contained in Site-56, which is currently set up under the guise of a petroleum processing company. Access to SCP-4169 is restricted to level 2 personnel and higher.
MTF Echo-5 ("Sting Operation") are assigned to Site-56 to aid with containment.

Any instances attempting to escape SCP-4169 are to be moved back into it on discovery. SCP-4169 is fed a live cow every 14 days to ensure that SCP-4169's fauna does not die out.

If any of the cameras placed within SCP-4169 receive damage, repair drones are to be dispatched as soon as possible to make the necessary repairs.

Description:
SCP-4169 is a chasm located in a remote area of Scotland, near █████. SCP-4169 is 257m in length with a maximum depth of 70 metres. The oxygen level inside and around SCP-4169 is at the same atmospheric level of 35% as in the Carboniferous era. It is unknown how SCP-4169 is capable of retaining the air pressure and oxygen level inside itself. SCP-4169 was brought to the Foundation's attention after a report about the carbon dating from the region around SCP-4169 was found to be inconsistent with other accounts. A facility was built above the entrance of SCP-4169 to prevent any civilians from entering and exploring SCP-4169.

SCP-4169's interior is small and dimly lit. The flora inside SCP-4169 is minimal due to the lack of sunlight that can enter the chasm. Previously undiscovered species of arthropods live within SCP-4169, those species are designated SCP-4169-1 through SCP-4169-6. How the colonies managed to survive from the Carboniferous era to the present is unknown. Researchers have theorized that the colonies are capable of hibernating for years at a time; this hibernation was most likely utilitized to survive harsh conditions. It has been noticed that the instances cannot live outside of SCP-4169 [see Incident 4169-3 for details].
The most notable and common species includes:

SCP-4169-1: An abnormally large species of Weta which resembles Deinacrida heteracantha that grows up to a meter long. Instances have been encountered in a variety of different colorations, most commonly: yellow, brown and black. SCP-4169-1 has been observed swarming prey in immense numbers.

SCP-4169-2: Arthropods resembling what appears to be Arthropleura armata. However, unlike Arthropleura armata which was thought to be herbivorous, SCP-4169-2 instances are carnivorous. It's theorised that the SCP-4169-2 evolved to counter the lack of flora and the harsh living condition inside SCP-4169.

SCP-4169-3: SCP-4169-3 are large predatory hexapods ranging from one to two meters in height which locate themselves at the boundaries of SCP-4169. Instances have a tendency to remain on the edges of SCP-4169 to catch and consume almost anything that approaches their pincers, using their natural black color to blend in within SCP-4169. The SCP-4169-3 instances are the most abundant species to emerge from SCP-4169.

SCP-4169-4: SCP-4169-4 are an unidentified species of predatory platyhelminth, lacking eyes or a face of any sort. Instances generally measure 2 to 4 meters long. SCP-4169-4 often scavenge but are perfectly capable of hunting a variety of different sized animals. SCP-4169-4 surround their prey, grabbing on to limbs, eventually consuming the victim whole. Instances of SCP-4169-4 have a symbiotic relationship with SCP-4169-3, the colonies of which use the SCP-4169-4 as hosts for hatching eggs⁹.

SCP-4169-5: SCP-4169-5 are dark-colored galeodid sun spiders measuring 15 to 20 centimeters in height. SCP-4169-5 possesses paralytic venom capable of causing significant pain to a human adult and paralysis to smaller animals.

SCP-4169-6: An insectoid resembling a cricket with mostly cylindrical, somewhat vertically flattened bodies, measuring 1.5 to 3 meters. Instances of SCP-4169-6 possess an exoskeleton made of tough chitin and two pincers that has been observed to be used while hunting. Their overall coloration resembles moss.

Incident 4169-3: On 29-10-201█, 5 SCP-4169-3 instances managed to break containment and begun wandering Site-56. During the roughly 2 hours when the instances escaped, four were found dead by Echo-5. The unit noticed that the last instance had trouble walking and standing up; instance was sedated and brought back in SCP-4169. One instance was kept for autopsy; the others were incinerated. Autopsy revealed the four SCP-4169-3 instances died of asphyxiation.

SCP-4169 Camera Feed - 06/07/20██

08:22: A cow was thrown into SCP-4169, multiple instances became aware of the cow and moved toward its position.
08:30: SCP-4169-5 are first to reach the cow and first paralyzed the cow before tearing off pieces of flesh, they were joined soon after by instances of SCP-4169-3, -2 and -4 whom fought over one of the legs before beginning to feed on the cow.
08:46: After the first instances finished eating, the SCP-4169-1 colony approached the carcass and began eating what was left.
09:05: Only bits of what the instances couldn't eat and bones are left, the SCP-4169-6 colony didn't partake in the feeding.
12:50: Fight broke out between several instances over territory, fight ended when an unidentified claw reached out of a hole to grab an instance of SCP-4169-2.
14:27: Instances of SCP-4169-3 seen scaling the walls of SCP-4169 towards the surface, instances seen descending soon afterwards after being pushed back by agents.
17:51: Several SCP-4169-6 attacked one of the surveillance cameras, repair drone sent in to restore the camera.
18:23: Communication with the drone was lost.

Addendum SCP-4169: 25 minutes after losing communication, the drone returned to the surface. It appeared to have been crushed despite the fact that none of the known instances are strong enough to cause such damage. An investigation to locate previously undiscovered instances may be warranted.
