SCP-XXXX post activation state.

Object class: Safe

Special Containment Procedures: SCP-XXXX is stored in a 3x3x4 meter steel vault in Site-██, with one wall substituted with a 3” sheet of glass-clad polycarbonate fitted with a biometric locking system that serves as the entrance to the containment area, as well as access point for security personnel and research staff to observe manifestations of instances of SCP-XXXX-A.

Instances of SCP-XXXX-A are to be kept in standard humanoid containment cell.

Description: SCP-XXXX is a 2x3 meter slab of concrete covered in a series of black discolorations that, through the testing of samples of SCP-XXXX, have been identified to be acrylic paint. Each patch of discoloration is mostly circular, with no one discoloration exceeding more than 5” in diameter, save for the central discoloration on the front of SCP-XXXX. In its dormant form, the central discoloration is instead ovular, measuring 11” through the semi-minor axis, and 2 meters through the semi-major axis.

Upon SCP-XXXX’s activation, the central discoloration will turn from acrylic to a black, viscous liquid comprised of ████-█████████, ███████, ███, [REDACTED], and salt. After several minutes the liquid will solidify into a membrane of the same chemical composition, and over the course of the next 7-9 hours, the interior of the discoloration underneath the membrane will turn from black, to the normal coloration of the rest of the concrete that comprises SCP-XXXX, forming the silhouette of a human being. The silhouette beneath SCP-XXXX’s membrane will began as vague at the start of the activation period, but will slowly take on more specific features as the activation period as underway. The specific features of this silhouette appear to be random, with no two silhouettes observed during SCP-XXXX’s active state appearing the same.

At the end of SCP-XXXX’s active state, the membrane formed over the central discoloration will turn black and then burst, releasing an instance of SCP-XXXX-A.

SCP-XXXX-A will be an adult human between the ages of 22 and 70, with each instance showing similarities to the silhouette that was created during the active state of SCP-XXXX for that instance. Like the silhouettes formed during the active state, each instance of SCP-XXXX-A is random in terms of age, race, sex, and physical attributes, with SCP-XXXX following no noticeable pattern in terms of the creation of instances. Instances of SCP-XXXX-A have shown to be fully cognizant, often displaying surprise, confusion, or anger after manifesting, as well as the ability to communicate in fluent English. While instances of SCP-XXXX-A almost always claim names and identities, not one has been identifiable by any database available to the Foundation.

ADDENDUM: SCP-XXXX was discovered embedded into a wall in the basement of ████ █████ in ████, New York after Mr. ████ called the authorities claiming that several nude intruders had somehow broken his way into the locked basement. Foundation agents embedded in the local police department intercepted the call and moved to Mr. ████'s residence, then determining that there was indeed an anomaly in the area after witnessing the beginning of SCP-XXXX's activation period. The Foundation agents then called for further personnel and transport, and Mr. ████ was given Class A amnestics. SCP-XXXX was then removed from the premises without incident to Site-██. From this activation period the first instance of SCP-XXXX-A, later designated SCP-XXXX-A-1, manifested while in Foundation captivity. The other instances of SCP-XXXX-A reported by Mr. ████ were not present when embedded Foundation agents arrived, and are believed to have escaped into the wild. A search team has been dispatched to the local area to locate and capture these instances.
