rating: 0+x

Item #: SCP-XXXX

Object Class: Safe

Special Containment Procedures: SCP-XXXX is to be contained in a standard humanoid containment cell, on occasion SCP-XXXX is allowed partial access to the Site-XX dormatories and recreational room per authorization of no less than █ Level 4 personnel. Under no circumstances is SCP-XXXX to remove it's protective sheaths while outside of it's containment cell, any breach of this protocol is to immediately be reported to Site-XX security personnel and SCP-XXXX is to be escorted back to it's cell.

Description: SCP-XXXX appears to be a genetically modified hominid bearing a strong resemblance to that of a female caucasian homo sapien of twenty years of age. SCP-XXXX's anomalous properties appear upon closer inspection of it's appearance, examination reveals that the subject's legs terminate just below the knee, revealing a smooth exoskeleton-like structure containing three forward facing claws. X-ray examination reveals vestigal, human-like feet with the remaining two toes encased in the structure. Composition of this exoskeleton is revealed through DNA testing to be a mixture of chitinous material, human skin, and an extremely durable form of keratinocyte capable of withstanding high amounts of shock, thus allowing SCP-XXXX to withstand falls from extreme heights. Testing also reveals that several of SCP-XXXX's reproductive hormones are non-functional, due to this the subject lacks secondary sexual characteristics, and is infertile. Effectively rendering SCP-XXXX the only one of it's kind.

The subject's head appears to have three small, pointy horns at the rear of the skull. With the subject's jaw and cheekbone being extended forwards 3", this gives SCP-XXXX a vaguely reptilian appearance. Leading some personnel to describe it as "menacing" or "predatory".

In addition to this, there is the presence of two blade-like growths on the subject's forearm. These "blades" grow out of the ulna, from shortly below the wrist to the elbow. The blades are triangular in shape, a short side extends outwards at a ~90° angle by the elbow, and the main blade is straight until it rejoins the ulna near the wrist. Due to the hazard these growths pose to Site-XX staff, SCP-XXXX is required to wear form fitting leather sheaths over the blades at all times outside of it's containment cell.

SCP-XXXX is normally docile, however it has been proven to display mild sociopathic tendencies and instinctual urges. SCP-XXXX does not appear to have any knowledge of it's identity or origin. When questioned about her origins, the subject replied, "I don't remember anything about what I may have been, but I do have frequent dreams of some cold, dark, metal place."[sic]

Addendum: Investigation into SCP-XXXX's origins are currently ongoing as of today's date (3/16/1█).
