Item #: SCP-XXXX

Object Class: Keter

Special Containment Procedures: SCP-XXXX is to be contained within an airtight cell, located at Site-104. The cell containing SCP-XXXX must be observed by surveillance cameras while being illuminated by a light source at all times. The cell must be connected with the outer hallway via a double airlock. The outer hallway must be equipped with liquid nitrogen sprayers on the ceiling every 2 meters.

When a surveillance camera or light source malfunctions, a Class D personnel equipped with a Class A hazardous materials suit is to enter the cell and repair the malfunctioning equipment. After repairing the equipment, the suit is to be frozen with liquid nitrogen and left in the airlock while personnel is to undergo a strict series of infection diagnosis tests and sterilization process.

Should contaminated personnel exit the airlock, Recontainment Procedure XXXX-Alpha is to take place.

All liquid nitrogen sprayers are to be activated while all surfaces personnel had come into contact with will be removed by MTF Beta-7 "Maz Hatters" and placed within SCP-XXXX's containment cell.

When an SCP-XXXX-1 instance has been located, Recontainment Procedure XXXX-Beta is to activate.

MTF Beta-7 will immediately quarantine the surrounding environment within a 5-kilometer radius. Thus the area is to be searched thoroughly for further SCP-XXXX-1 instances, while all discovered SCP-XXXX-1 instances are to be instantly destroyed using liquid helium and carried to Site-104 using a cube Silicon container with each walls being at least 2 centimeters thick.

In either case of containment breach, all equipment, including hazmat suits, that has been used for operation will be frozen by liquid helium and placed within the cell.

Should information regarding SCP-XXXX is revealed to the public, those who have knowledge about the information, other than Foundation personnel, are to be administered Class C amnestics while all information is to be either deleted or distorted by Foundation agents.

Description: SCP-XXXX is a microscopic single-cell protein-based organism. When under lab conditions, it appears to be non-anomalous, duplicating itself by absorbing nutrition around it and processing it to generate energy and waste material, which has been identified as carbon dioxide and ammonia.

It's true anomalous property, however, is revealed when it makes contact with a living being. Once introduced to a living organism, SCP-XXXX will start assimilating the organism's cell, ultimately resulting in the total assimilation of the organism. The process is estimated to take approximately 12~18 hours and SCP-XXXX does not emit any waste material or require nutrients. The assimilated organism, hereby referred to as SCP-XXXX-1, cannot be identified with the naked eye and has the ability to secrete a gooey substance, which has been identified as SCP-XXXX. When under threat, SCP-XXXX-1 also has the ability to transform a part of itself into a gooey tendril, with the intention of attacking and subduing its opponent, while allowing its own replication.

It has been revealed that SCP-XXXX-1 instances practically do not need sustenance to maintain its form; instances of SCP-XXXX-1 have been observed to thrive up to 29 years without gaining access to any form of nutrients. SCP-XXXX-1 instances are also capable of retaining their host's memories, allowing them to easily assimilate into the host's society.

Experiments have revealed that SCP-XXXX possesses a DNA chain completely unrelated to lifeforms on Earth, suggesting that it is of alien origin. Due to this, and SCP-XXXX's own non-emitting characteristic, the process behind SCP-XXXX's metabolism is yet to be explained.

SCP-XXXX was discovered on May 17th, 1987, approximately 380 kilometers above the Earth's surface. SCP-XXXX was found sticking to the windows of the Russian Space Station Mir by cosmonaut Yuri Stratensiko as "a form of transparent goo". He took a sample of it, which returned to Earth aboard the Soyuz TM-2 spacecraft and was taken to [REDACTED], a former Soviet laboratory located in the Siberian plains.

According to logs recovered from the laboratory(See L-97-SB-XXXX Experimentation Log), after 4 years of constant research on SCP-XXXX, one of the researchers were contaminated. Said researcher assimilated into the society of the laboratory personnel and was able to hide its true form for another 6 years. However, once its true nature was exposed, it proceeded to attack researchers who tried to restrain it, resulting in a single survivor among the 67 laboratory personnel. Said survivor was secured by the Foundation, interrogated about the incident, applied Class A Amnestic and released into the world under a new identity(See Interview Log XXXX-MG-11-04-2000).

The incident was reported to the Russian government, while Foundation agents acting within the government reported it to the Foundation. The lab was shut down under the cover story of budgetary restrictions. Foundation agents recommended decommissioning the Space Station but were denied by the Russian government due to budgetary and technological reasons.

Even after Foundation agents contained the abandoned research lab on August 27th, 1997, Mir kept operating normally, allowing SCP-XXXX to thrive. On March 2nd, 1998, a lab mouse which was carried to Mir for scientific experiments was contaminated by SCP-XXXX, which then proceeded to contaminate other lab mice as well. By the time the crew discovered the "mice's" true form, more than 20 specimens had been contaminated, with assimilation continuing on the other mice specimens.

The incident caused controversy about the safety of the astronauts, which eventually led to the decision to decommission Mir.

Space Station Mir was de-orbited on March 21st, 2001. Foundation agents were able to secure a sample of SCP-XXXX on May 7th, 2001, despite having agents ██████ and ███████ contaminated, caused by SCP-XXXX-1 instances which were infesting within the lab. Said agents were terminated immediately. It was at this point the abilities of SCP-XXXX-1 became well known(See Acquisition Report XXXX-05-07-2001). On July 6th, 2001, the lab was emptied of its contents while every single trace of SCP-XXXX was removed and moved to Site-104.

Since various samples of SCP-XXXX-1 has been secured, various methods have been applied to slow or even halt SCP-XXXX-1's activity; although none were successful in stopping it, several materials appeared to be effective in slowing it down. Furthermore, multiple attempts to destroy the organism have been made, which were all met with failure. These attempts include:

  • Putting it in ethanol
  • Burning it with a flamethrower
  • Supercooling it via coolants
  • Exposing it to high energy radioactive rays
  • Providing it antibiotics
