Artist's depiction of SCP-X, based on the reports of three SCP-X-1 instances.
Item #: SCP-X
Object Class: Keter
Special Containment Procedures: MTF Omega-76 "Neighbourhood Watch" is to investigate any subjects who show signs of being SCP-X-1 instances.
Once SCP-X's presence is confirmed, MTF Beta-23 ''Rare Venture'' is to be dispatched to its present residence and detain it with pressure sensors and laser detectors. The current SCP-X-1 instance is to undergo psychological treatment and be returned to its home, after the full administration of Class-B amnestics to both it and its family members.
SCP-X is to be placed in a specialized containment cell to ensure its presence at Site-127, up until a X-A "Bloom" Event.
Description: SCP-X is a Megascops kennicottii1 with elongated femur, tibiotarus and fibula bones, standing at 1.3 meters tall. SCP-X is completely transparent when perceived by post-pubescent individuals, and will randomly select and become emotionally attached to a random subject that is capable of perceiving it, henceforth SCP-X-1.
Children are capable of viewing SCP-X from birth up until early puberty (typically between the ages of 6-8); these individuals may view SCP-X physically, digitally and photographically. Memories of SCP-X may be retained after losing the ability to see it. Once adrenarche of the current SCP-X-1 instance occurs, SCP-X will undergo an X-A "Bloom" Event, resulting in the following:
- SCP-X will rapidly expel air from its orifices
- Rapidly lose mass
- Involuntarily ricochet around the room until it disappears from view entirely
- Spontaneously remanifest in the presence of a new SCP-X-1 individual.
