A rare image of SCP-XXXX’s silhouette, windows have sense been removed from it’s containment chamber.

Item #: SCP-XXXX

Class: Euclid

Special Containment Procedures: SCP-XXXX is to be kept in a large containment chamber with no windows. A smaller, portable containment unit should be attached to the door. Two lights are positioned in the chamber to not shine into the smaller unit if on, these lights must remain off when not testing.
Description: Most of SCP-XXXX’s physical appearance is unknown, but it’s frame appears to be humanoid based off silhouettes. SCP-XXXX does not emit any body temperature and is therefore not visible with infared cameras.

If SCP-XXXX is threatened by a light level that would reveal it’s physical appearance it moves instantly to the closest dark area. If no area is available, SCP-XXXX let’s out a ear-splitting shriek that causes all instances of nearby lightbulbs to shatter and knocks unconscious all nearby personnel. Personnel affected by this are rendered deaf, and do not remember SCP-XXXX’s physical form, if seen.

SCP-XXXX is hostile towards any large organism that it is presented with. It is currently unknown how SCP-XXXX kills it’s prey, but all incidents end up with the organism’s eyes cleanly removed.
