Four vials of SCP-121

Item #: SCP-121

Object Class: Safe

Special Containment Procedures: SCP-121 is to be collected in a re-enforced four Liter (4 L) clear plastic hazardous materials containment jar. When full, this jar is to be changed by qualified medical personnel wearing level two biohazard gear. If SCP-121 is accidentally exposed to the skin, compromised personnel must be subjected to emergency decontamination procedures and sensory deprivation for 90 minutes, followed by a full psychological evaluation. If SCP-121 is somehow accidentally introduced to a mucous membrane or directly into the blood, the affected subject must be isolated immediately with no verbal or written communication between them and unaffected personnel lest accidental psychological damage occur to the subject. Isolation to be maintained until twelve (12) hours have elapsed per CC of exposure. Under no circumstances is SCP-121 to be introduced directly into the subarachnoid space of a living human's spinal column or cranial cavity.

SCP-121-1 is to be kept in a sterile holding cell equipped as a standard hospital room for catatonic or quadriplegic patients, and is to be maintained as such with the following exceptions:

  • SCP-121-1's intravenous nutrient feed must have four times the standard capacity and nutrient contents.
  • The subarachnoid space surrounding SCP-121-1's spinal cord is to be catheterized, and SCP-121 is to be drained once every twelve (12) hours.

Now that we have the relevant tissue cultures to produce the stuff ourselves, SCP-121 should only be drained directly from the subject when needed for comparison or research purposes. - Dr. Nord

Description: SCP-121 is the cerebrospinal fluid of SCP-121-1. When introduced into the bloodstream of a baseline human, either through direct injection or contact with a mucous membrane, it acts as an extremely potent hallucinogen and mnemonic hazard, putting the affected subject in a state of total suggestibility. Subjects thus affected will not only do or believe anything they are told, but if given a scenario and told they experienced it will fill in the details themselves, believing totally and without reservation in the veracity of the new memory even after SCP-121 wears off.
The state of suggestibility persists for approximately four hours per CC of SCP-121 in the bloodstream.

Exceptional Cases for SCP-121

  • If the subject is given a scenario which they possess inadequate knowledge to accurately construct, they will remember it as they would imagine it to be, sometimes to the point of gross inaccuracy.
  • If the subject is given a scenario containing information that directly contradicts a well established element of their personal history or sphere of influence (I.E, they have been visiting their mother but their mother passed away several years ago), one of several things can occur, depending on the subject. In 40% of cases, a total rewrite of related and peripherally related memories will occur over the course of several days, well outside of SCP-121's normal active period, eliminating the conflict. In 30% of cases, the subject will become fixated on the conflicting memories, lapsing into a state similar to paranoid schizophrenia within 72 hours. In 25% of cases the subject will immediately enter a state of grand-mal seizure, which will persist until death. In 5% of cases [DATA EXPUNGED] in the event of which the subject should be immediately terminated.

SCP-121-1 appears to be a man is his early to mid thirties (actual age ██) suffering from muscular atrophy due to long-term inactivity. The subject is missing his eyes and 90% of his frontal lobe as the result of a high-calibre gunshot wound sustained during initial retrieval. Despite his injury SCP-121-1 is still alive, but totally devoid of nervous system functionality above the autonomic level, lacking even the most rudimentary of higher brain functions.

SCP-121-1 possesses a variety of unusual physiological and biochemical characteristics related to his former abilities, several of which were responsible for his initial survival post-retrieval. A more detailed summary of the subject's physical anomalies can be found in medical document MRD-121-371757, but the most prominent, not including SCP-121, are listed here.

Notable Physical Anomalies Present in SCP-121-1

  • Subject is missing his left lung, the resulting cavity filled by several organs previously unknown to medical science. The function of these structures is largely a mystery (tests are ongoing) but the largest, positioned beside the heart with several vascular connections to the superior vena cava, appears to [DATA EXPUNGED]
  • Subject's blood contains elevated levels of glucose, as well as a host of previously unidentified enzymes and a non-toxic variant configuration of [DATA EXPUNGED] also [DATA EXPUNGED] unknown why it does not make SCP-121 more prone to fatal blood clots or cancer than a baseline human subject.
  • Subject regenerates damage to nerves and associated structures at an accelerated rate, roughly seventy (70) times that of a standard human. Obviously, this is unable to rebuild the missing sections of his brain, but it is presumed to have played a large role in helping to keep him alive by mitigating damage to the hindbrain and related structures.

History: Prior to retrieval, SCP-121-1 was ██████ ██████████, ██ ██████ ███████, ███████ ███████. He came to foundation attention on █/█/19██ when he was seen exchanging briefcases with known agents of Marshall, Carter & Dark. Approximately 36 hours later [DATA EXPUNGED] consistent with Class Four catastrophic post-human manifestation was detected in ██████, resulting in █ deaths and ██ injuries. Class-B amnesiacs were administered to survivors and cover story Blue Skies 19 (freak lower atmospheric heat burst) was implemented. Mobile Task Force Delta-39, AKA "Kryptonite", dispatched. Target retrieved with acceptable casualties. During standard chemical testing of the subjects bodily fluids, the unusual properties of SCP-121 were inferred due to the presence of [DATA EXPUNGED]. Unusual properties were confirmed in laboratory trials.

Addendum 121-A: Results of Testing of SCP-121

In addition to establishing its mind-altering properties, testing of SCP-121 has determined the overdose threshold to be approximately 20 CC's, varying from subject to subject. Overdose results in the major components of the subjects nervous system (excluding the brain but not the spinal cord) hardening to a consistency not unlike that of muscle tissue and tearing free of the body, at which point they will violently attack any nearby personnel for several minutes before expiring from lack of vital nutrients and reverting to their former state. Overdose is to be avoided at all costs. Introduction of SCP-121 into a baseline human subject's spinal column or cranial cavity results in [DATA EXPUNGED] similar to SCP-121-1's original abilities for approximately ten (10) minutes, at which point the subject expires of a massive cerebral hemorrhage.
