Per 
Special Containment Procedures:
SCP-GGGG is to be kept in a level 2 standard bio-hazard containment cell. No metallic equipment may retain inside the containment chamber for prolonged periods of time. If SCP-GGGG is to be transferred, the containment cell must not contain metallic structural components.
Incendiary equipment must be kept readily available.
By order of the Overseer Council, the preceding procedure is suspended, as no potentially lethal weaponry is to be utilized as part of the containment procedures.
Update 1 (04/07/2018): Following incident GGGG/1, all personnel with security clearance level 2 or higher must not enter the containment chamber of SCP-GGGG but act through proxy, using lower clearance staff or D-Class personnel.
By order of the Overseer Council, the preceding procedure is suspended, as all non-structural containment procedures are to be replaced with procedure GGGG-Mutiny.
Following incident GGGG/1, a secondary chamber was constructed around the aforementioned standard bio-hazard containment chamber that is outfitted with optical motion detector sensors. The two doors must be connected through an airlock mechanism. The airlock is to be equipped with computer-guided directed-energy weaponry with at least 180 kW continuous power output.
By order of the Overseer Council, the preceding procedure is suspended, as no potentially lethal weaponry is to be utilized as part of the containment procedures.
Update 2 (12/12/2018): By order of the Overseer Council, in case of further containment breaches, the expiration of SCP-GGGG is to be prevented under any circumstances. No lethal weaponry must be utilized during any containment attempts of SCP-GGGG.
SCP-GGGG must not be transferred to a facility equipped with a nuclear fail-safe option. If the current containment site of SCP-GGGG is ever equipped with a nuclear fail-safe, SCP-GGGG is to be transferred to a biological containment facility without an on-site nuclear fail-safe immediately.
Update 3 (12/12/2018): By order of the Overseer Council, all non-structural special containment procedures of SCP-GGGG are to be replaced with procedure GGGG-Mutiny as described in the end of this document.
Description:
SCP-GGGG is an organic life form similar in structure to mycelium that is connected to a variety of quasi-deceased mammalian creatures through a network of hyphae. The connected creatures, unless recently integrated into SCP-GGGG, have suffered total organ failure and are subject to advanced decomposition. Often, only the skull and vertebral column accompanied by the fully intact and functional brain and its brain stem remain.
SCP-GGGG is capable of movement through partially contracting cells along its hyphae through undulatory locomotion. The contraction of cells is volitional and precise. Since SCP-GGGG does not possess visible perceptive organs or similar mechanisms, guidance and control of such movements are hypothesized to have anomalous origin. When not moving, the structure usually clings to walls and surrounding structures using a biochemical adhesive. During movement, the hyphae structure is able to support the amorphous mass of SCP-GGGG and its attached neural tissue through its contractive forces.
The hyphae network keeps attached neural tissue alive by feeding it with a solution of glucose-based carbonhydrates and several electrolytes. Since the structure does not absorb enough matter to compensate, the origin of the nutrition is clearly anomalous. Furthermore, the hyphae are capable of exchanging electric signals between attached neural tissue samples at high frequency. Using those, SCP-GGGG is believed to be capable of reaching a consensus consciousness utilizing all attached neural tissue.
Addenda
Within several hours after incident GGGG/1, SCP-GGGG began to show clear signs of a sapient consciousness and the ability to produce biological agents at will. Specifically, it has been observed to produce compounds that are able to denature and subsequently destroy common metals (like iron, steel and nickel) and polysiloxane fabric.
Furthermore, it has altered its biological structure by vastly changing the composition of several proteins found within the hyphae structure to be increasingly resistant to heat. Additionally, it developed a shell around integral parts of its main stem from several metallic alloys that is capable of quickly dispersing directed heat. A network of newly developed vessels among its hyphae is capable of quickly pumping a solution of several biosynthesized polychlorated biphenyls to select locations around its tissue and shell, capable of further cooling the shell structure when heated or burned directly.
Assigned research staff assumes these changes to be a direct counter measure against existing containment procedures and thus Update 1 of the procedures was established. Despite those efforts, SCP-GGGG tried to breach containment on multiple occasions adapting to obstacles when encountered. A table listing the incidents can be found below.
| Date | Description | Notes |
|---|---|---|
| March 27, 2018 | SCP-GGGG produced several protein-based compounds capable of destroying iron, steel and nickel-based alloys by catalyzing an oxidation of a secondary compound using the metal. With these chemicals it corroded the containment chamber surfaces. | Staff identified aluminum- and tungsten-based alloys to be completely unaffected by the breach attempts of SCP-GGGG and the containment chamber was subsequently reinforced with aluminum sheets. |
| March 29, 2018 | SCP-GGGG produced a protein-based compound capable of corroding aluminum at very high speed. Within minutes, it destroyed the entire aluminum sheet protecting the containment chamber surfaces by corrosion. Electrical breach alarms triggered and alerted containment staff. | Researchers assume that SCP-GGGG intentionally left aluminum unaffected in the previous breach attempt to induce a higher reliance on aluminum in containment protocol. SCP-GGGG was relocated into a level 02 bio-hazard containment chamber1. |
| May 05, 2018 | SCP-GGGG managed to breach a steel cover at the inner airlock module and subsequently shorted multiple electrical wires in an attempt to override the door mechanism. | The closing mechanism was digitized and the electronics were protected against sophisticated tampering. |
| September 30, 2018 | SCP-GGGG attached multiple strands of hyphae onto the pins of a microprocessor and reverse engineered the basic protocol of the code lock mechanism that was controlled through the microprocessor. It triggered an alarm when attempting a brute-force attack against the security code for the code lock. | The microprocessor was switched to a x64 dual core processor and repositioned within the airlock. The lock was replaced with a high-power electromagnetic bolt lock, so no electronics had to reside adjacent to the chamber surface. |
After the last incident, movement of SCP-GGGG decreased to a minimal amount and no further breaches were attempted until incident MMMM/2-GGGG.
After the incident BIONAF periodically reported high concentrations of different protein-based toxins, each time triggering the venting protocol. Air samples taken from the containment chamber in between venting procedures and subsequent analysis revealed the almost continuous presence of different proteins, in many cases revealing close resemblance to protein-based neurotoxins, albeit often undetected by BIONAF. Thus Site Command sealed the containment chamber until BIONAF reports ceased.
Approximately 26 hours later the chamber was reopened. By this time, SCP-GGGG had begun to excrete vast amounts of a clear fluid which analysis showed to have close resemblance to human cerebrospinal fluid. Furthermore, a black, as of yet unidentified fluid had coagulated between joints of hyphae and neural tissue. Electromagnetic scans showed increased activity along the entire structure. At this point research staff tried to edit the documentation, discovering Update 2 and Update 3 to the containment procedures, which had not been announced by the respective editor.
Procedure GGGG-Mutiny
By the order of the Overseer Council, all non-structural special containment procedures are to be replaced with the following procedure.
A live strand of hyphae of SCP-GGGG is to be obtained by cutting it out of its tissue. Until closure of this procedure, it is designated SCP-GGGG-2, while the original specimen is designated SCP-GGGG-1.
The obtained instance of SCP-GGGG-2 is to be kept at a secondary level 02 bio-hazard containment cell. Once a day a live mammal is to be anesthetized and then attached to the structure of SCP-GGGG-2 by placing it in the containment cell near SCP-GGGG-2. Using this method, a secondary specimen of SCP-GGGG is created over a time span of two weeks.
After this time span, or if SCP-GGGG-1 shows signs of imminent brain death, SCP-GGGG-2 is to be transferred back into the containment cell of SCP-GGGG-1 and held there, until either of the specimen tries to incorporate the other into its hyphae structure. This process will take approximately 10 minutes. As soon as the integrated instance ceases all signs of activity (i.e. movement of its hyphae structure), the remaining specimen is redesignated as SCP-GGGG.
The procedure is then to be repeated.
