Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX is to be housed in a six by six by three meter containment cell and encased in a seven and a half centimetre thick steel tungsten container no more than ten centimetres in length, width, and height. Following incident XXXX-003, the tungsten container is to be placed between vibration-sensing panels for the purposes of monitoring SCP-XXXX's activity within its containment cell. There are to be at least two armed guards stationed outside of its containment chamber at all times. Researchers assigned to SCP-XXXX are to view the container housing SCP-XXXX through a monitor connected to the vibration-sensing pads around its tungsten container in addition to a remote video feed of its containment cell. Any erratic movement by SCP-XXXX should be reported to site administration immediately.

All testing of SCP-XXXX is currently prohibited without clearance from at least three members of the O5 Council and any unnecessary biological material is prohibited from coming within a fifteen meter radius of the entity. Individuals purposefully bringing SCP-XXXX any biological matter without administrative clearance strictly for testing purposes are to be interviewed for any connections to groups of interest and then terminated.

Description: SCP-XXXX is a small processing unit bearing the inscription 'N-79184'. It is approximately half a centimetre thick, two centimetres in length and width with five centimetre long spider-like legs made of an unknown, strong, and highly flexible material. Identifying the materials that make up SCP-XXXX, as well as attempts to terminate it have proven unsuccessful as it has shown to be totally resistant to extreme temperatures and pressure, and even EMPs. The entity uses vibrations felt in its legs to map out its environment and detect potential victims from within a six meter radius, however it has been observed harvesting its victim's eyes and other sensory organs to broaden its senses.

Upon coming within six meters of any living macroscopic organism, hereby referred to as SCP-XXXX-2, SCP-XXXX will attack and attempt to kill or subdue SCP-XXXX-2 in order to assimilate its bones, skin, organs, sinew, or muscular tissue into its mass hereby referred to as SCP-XXXX-1, constructing its body out of whatever it can scavenge from its victims, then controlling SCP-x-1 with electricity emitted from its legs. Testing has shown that SCP-XXXX typically prefers building itself into a humanoid form and in its more advanced stages it tends to pick and choose which body parts it builds SCP-x-1 with, even upgrading or outright discarding preexisting ones already incorporated into SCP-XXXX-1 that it deems obsolete. It has been observed to mainly attack mammals, including but not limited to small rodents, large predators, and humans. In some extreme cases however, insects have been utilized by the anomaly. (see attached incident report). The method which SCP-XXXX uses to determine biological from non-biological matter is currently unknown and it is believed that it does not need to consume energy to sustain itself.

In the early stages of its construction, SCP-XXXX mainly focuses on overall structure and mobility, opting for speed and tensile strength. The object will then focus on weaponizing itself, typically in the form of sharp, long reaching melee weapons attached to the arms of SCP-XXXX-1 or protruding from other areas of the body. In one incident however, it did use matter extracted from various species of ████ to create a flamethrower, nearly breaching its containment. SCP-XXXX will always attempt to build itself into a sleek, stealthy predator, favoring evading and stalking rather than outright assaulting its prey. SCP-XXXX does not utilize weaponry composed of non-biological material. In rare instances, SCP-XXXX has been observed to utilize firearms taken from fallen Foundation personnel.

A key weakness in SCP-XXXX is the biological nature of SCP-XXXX-1. Given that the entity builds its body out of decaying organic material, individual components of SCP-X-1 begin to break down over a period seventy two hours after their extraction from SCP-XXXX-2. SCP-XXXX-1 needs constant a rotation of new “parts” to counter its constantly decaying state, often leading to pieces of SCP-XXXX-1 being replaced with inferior “parts” out of necessity. Depending on the environment SCP-XXXX finds itself in, this can lead to a degenerative evolution of SCP-XXXX-1, as it becomes less efficient over time due to a lack of robust or available prey.

While thought to be incapable of communication, SCP-XXXX has shown high technical and kinesthetic intelligence. It will often attempt to outsmart its containment procedures as well as the researchers assigned to it. Under no circumstances is SCP-XXXX to come into contact with any biological SCPs.

Discovery: SCP-XXXX was discovered on the Russo-Mongolian border in 1976 by Alexei Prokofiev, a Foundation Informant working within the Soviet GRU. Agent Prokofiev, now SCP-XXXX-2 managed to activate its Foundation issued distress beacon as SCP-XXXX used its claws it had built prior to contact with SCP-XXXX-2 to tear open SCP-XXXX-2's back and extract its spine.

Upon arrival, retrieval team MTF Omega Orange began surveying the area for SCP-XXXX and were then ambushed by the anomaly, which is estimated to have been at 1.32 times its previous mass after assimilating agent Profokiev based on later autopsies. SCP-XXXX shot up from the ground and pulled agent Banzragch into a deep, winding tunnel system it had been residing in. MTF agents Genrich and Baatar entered the tunnels armed with grenades, two sub-machine guns, and two flashlights. Neither of the agents were heard from for half an hour. After the remaining Omega Orange agents on the surface realzied several of their other task-force members had also silently gone missing, MTF Epsilon-6 ("Village Idiots") were called in to deal with the anomaly. Ground sonar was used to detect SCP-XXXX's presence in the tunnels, which were subsequently torched.

The scorched remains of SCP-XXXX were retrieved and transferred to Site-█ where the true nature of the anomaly was discovered during the autopsy of SCP-XXXX-1, at which time was assumed to be SCP-X, after it leaped at researcher Bernard F. Hudson from the chest cavity of SCP-XXXX-1 and then attempted to escape through a ventilation shaft. Foundation personnel managed to block the entity's passage and extract it from the vents using a portable electric saw. Upon capture, SCP-XXXX was discovered to have utilized the remains of two rats it had found in the vent, presumably either for greater mobility or as an attempt to evade detection.

INCIDENT #: XXXX-6
DATE OF OCCURRENCE: 1976/07/12

Far into initial testing of SCP-XXXX, two security personnel each equipped with one standard Foundation issue sidearm and one flamethrower entered SCP-XXXX's containment cell to reset the state of SCP-XXXX-1 as per testing protocol. SCP-XXXX then shot out what Foundation researcher Lind Garret described as a “sort of makeshift spring loaded harpoon” from its right arm, impaling one of the security personnel, then retracting the projectile fired from SCP-XXXX-1, pulling him towards SCP-XXXX, which then acquired his sidearm. Using the impaled man as a shield against the remaining security personnel's flamethrower, SCP-XXXX shot its assailant in the head, killing him instantly.

What followed was the slaying of half of the research team assigned to SCP-XXXX as well as other unrelated staff until MTF Omnicron-3 were able to evacuate most Foundation personnel from the surrounding area and subdue SCP-XXXX with incendiary grenades, unavoidably incurring additional Foundation loss of life and extensively damaging the wing SCP-XXXX was hosted on. All testing on SCP-XXXX is suspended until further notice

A foundation researcher assigned to SCP-XXXX entered its containment cell for routine testing at 0900 hours and discovered a hole in the side of SCP-XXXX's steel container, and promptly alerted administration at Site-█ to a containment breach. MTF Omicron-3 arrived on-site and could not locate SCP-XXXX within its containment chamber. Upon further forensic inspection, it was discovered that SCP-XXXX had scratched through its ten centimetre thick steel container over the course of nearly a year, subsequently escaping its containment cell via the roof mounted incinerators installed for testing purposes.

An extensive site-wide search was performed throughout Site-█, involving the dismantling of floors, walls, and air vents. Several D-Class personnel were terminated and placed in various locations around the site along with a monitoring armed guard with the intent of luring SCP-XXXX out of hiding. After seven hours, SCP-XXXX was discovered by a member of MTF Omnicron-3 after he had stepped on a large cockroach that had been serving as SCP-XXXX-1. He examined the insect closer and noticed the odd protrusions on its thorax, as well as spider-like appendages jutting out from its abdomen. MTF Omnicron-3 agent then immediately announced contact with SCP-XXXX over his radio and caught the entity in a steel cylindrical container.

SCP-XXXX appears to be intelligent enough to realize it is being held in captivity, as it has demonstrated a calculated effort to breach its containment and elude Site-█ personnel, as well as the ability to restrain itself from incorporating tissue from the exterminated D-Class personnel used as bait into SCP-XXXX-1 in order to evade detection. Changes in SCP-XXXX's containment procedures have been deemed necessary for future containment.

During a routine inspection of SCP-XXXX's containment cell, SCP-XXXX [DATA EXPUNGED] D-2246, who had been assigned to SCP-XXXX's maintenance detail. SCP-XXXX then [DATA EXPUNGED] right eye and proceeded to burrow into [DATA EXPUNGED] and proceeded to bolt through the door as the security personnel assigned to SCP-XXXX came into its containment cell to relieve D-2246 and contain SCP-XXXX. What followed was the longest ongoing containment breach of a single SCP in Site-█'s history, lasting for a period of two months. Site-█ was initially under full lockdown until it was deemed safe for researchers to return to the facility due to SCP-XXXX's perceived inactivity. During this time, several D-Class and maintenance staff had gone missing.

SCP-XXXX was discovered by maintenance staff at Site-█ in the lower-level boiler room. SCP-XXXX had mounted itself to [DATA EXPUNGED], hidden away from sight and had been using eyes harvested from mostly D-Class and several of the maintenance staff attached to long, thin tentacle-like appendages to spy on various low and high security level areas of the facility. It achieved this through use of ventilation shafts and small tunnels it had burrowed through the middle of the site's floors and walls. The boiler room was quarantined and flooded with fluoroantimonic acid. Later efforts to recover the remaining remnants of SCP-XXXX-1 from various holes, ventilation shafts, and other hidden areas of Site-█ have accounted for seventy one separate eyes in total. Investigation into Site-█'s administrator for negligence is currently pending.
