Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be kept inside a 2x1x1 metre steel sarcophagus at all times, with an average thickness of 5 centimetres per side. The upper plate of the chamber is removable and must be kept locked in place with four (x4) cam locks, in addition to two (x2) crossbar bolts placed longitudinally. The locks require daily testing, to be performed between 0800-1800 hours; any failures are to be reported and repaired immediately. SCP-XXXX may be removed for study between these hours, but not without approval from O5-█.
The sarcophagus of SCP-XXXX is to be kept on base at Site-██ and monitored at all times with cameras and motion sensors. Any anomalies detected are to be reported immediately, followed by the lockdown of the sarcophagus’ containment. Subsequent investigation and analysis are to be conducted between 0800-1800 hours; all staff found attempting to enter the containment area before or after these times will be subject to disciplinary action.
Description: SCP-XXXX is the corpse of a Caucasian male, age unknown, discovered on ██/██/████ in Demecser, Hungary. The subject appears to have suffered from anaemia and severe muscular dystrophy prior to death. Autopsies conducted on the subject have failed to determine the cause(s) of its condition but have revealed severe blood clotting in both the eyes and the circulatory system. The subject first came to the attention of the organisation after a series of attacks on both farmers and livestock in rural Hungary and was captured after a lengthy pursuit by field operatives (see Addendum 01).
Between 1900-0700 hours (local time, see Addendum 02) the subject will reanimate and, unless restrained, will seek out the nearest living mammal to its position and feed on its bone marrow; given enough time, up to 90% of the victim's marrow will be consumed. Upon finishing, the subject will continue to hunt until shortly prior to 0700 hours, at which point it will attempt to seek out an isolated location before returning to an inert state. The subject exhibits no response to pain or physical stimuli and testing has revealed a lack of brain activity during its animate state; as a result it is considered to be non-sentient (see Addendum 03).
The subject exhibits disproportionate strength in comparison to its lack of muscular tissue, and has been observed to be capable of tearing through Kevlar body armour under laboratory conditions. Experiments have shown that whilst exhibiting a preference for human tissue, the subject will consume any mammalian samples in its vicinity. Attempts to feed it avian, reptilian and amphibian samples have so far been unsuccessful. Regular feeding has been observed to improve both the subject’s muscle mass and skin tone, granting it a progressively healthier appearance.
Addendum XXXX-01: Field Agent Coulson was injured during the operation but despite severe trauma to the anterior muscles of his right thigh, he showed no sign of physical discomfort for approximately ██ hours, at which point sensation gradually returned. Tests to determine the potential anaesthetic properties of SCP-XXXX are pending.
Addendum XXXX-02: The time of reanimation roughly corresponds to the local timezone. It has been proposed to keep the subject moving through time zones to keep it in its inanimate state, but due to logistical reasons this is seen as unreasonable.
Addendum XXXX-03: During its initial capture, the subject was observed to be capable of speech and apparent emotion. Subsequent testing has revealed a limited range of responses and actions, with little to no problem-solving ability. It has been proposed that the subject is able to utilise memories from its victims to make it a more efficient hunter, but is otherwise only capable of rudimentary thought.
