Item #: SCP-4151
Object Class: Euclid
Containment Procedures: SCP-4151 is to be contained in a small air-tight cryo chamber in Site-██
The chamber is to be sealed shut at all times and guarded by Level 4 personnel or higher and must be monitored at regular intervals.The temperature of the chamber MUST stay within the bracket of -50 to -60 degrees celsius. Should the temperature fall even 1 degree out of this bracket a containment breach is highly probable.To combat this, The cryo chamber is to be completely sealed by tape doused in Liquid Nitrogen as its secondary containment ,and the tape is to be re-coated in Liquid Nitrogen every 12 hours .It must also be noted that infrared cameras are to remain affixed on 4151's chamber all day and every day to monitor movements.
Any experimentation on SCP-4151 currently awaiting approval from at least 2 Level 4 personnel or higher
Description: SCP-4151 appears to be a diminutive, dark ghost-like figure, with bright white eyes and mouth that are illuminated on its face. The figure appears to also have short arms and legs that are proportionate to its body. Due to the figure's ethereal state any measurements on weight are non-applicable. But we estimate the figure is somewhere between 152 and 162cm in height, though we do not have an official recording of its height.
The figure is not innately malicious at all but appears to pose some threat to on-site personnel as a result of his mischievous behaviour. The being is poltergeist-like in nature and an advocate of mischief and delinquency, and would move around the facility causing trouble, namely breaking the [REDACTED] and trashing the C wing of Site-██ ,and anything that was made contact with by SCP-4151 is coated with a thick black stain that cannot be removed. Its most notable anomalous property however, is its ability to recreate itself as a manifestation of someone known to one, be it a friend or a relative. It must be noted that SCP-4151 cannot manifest itself as deceased personnel, only beings who are living. SCP-4151 does not do this to spite or upset anyone in the facility, it seems it sees everything it does as some sort of game or trickery. The one proven method of preventing SCP-4151 from causing such confusion around the facility is to seal it in an air-tight cryo chamber with the temperature set anywhere between -50 and -60 degrees Celsius.
It is understood that should anyone be able to capture SCP-4151 that the temperature MUST stay within this temperature bracket, because if it were to fall outside the bracket, SCP-4151 can simply phase through the cryo chamber, regardless of whether or not it is sealed up, it is currently unknown why SCP-4151 cannot phase through the chamber at temperatures -50 to -60 degrees Celsius. It is also understood SCP-4151 cannot manifest when in close proximity of Liquid Nitrogen, with reports claiming when near Liquid Nitrogen it begins to squeal loudly and a burning aroma fills the air.SCP-4151 can also not phase through any object that has been coated in Liquid Nitrogen. However, because SCP-4151 likes to manifest often and it is inconclusive exactly the time gate between manifestations, as well as attempting to distinguish the genuine person from the SCP-4151 manifestation and then detaining SCP-4151 proves incredibly difficult and can result in mistaken identity. The one sign that is given off that distinguishes the SCP-4151 manifestation from the actual person is faint black smoke coming from every orifice on the manifestation's face, though at times this can be difficult to notice.
