Object: SCP-[cannot be classified]
Object Class: Keter
Special Containment Procedures:
SCP-[cannot be classified] is to be contained in a reinforced underground isolation chamber at Site-██, equipped with motion sensors, thermal cameras, and automated lighting systems. Under no circumstances should personnel enter SCP-[cannot be classified]'s chamber when the lights are off.
All maintenance must be performed remotely or by Class-D personnel during full illumination. If the lights flicker or fail, the chamber must be immediately locked down and power rerouted. Any personnel reporting visual contact with "the smile" are to be quarantined and psychologically evaluated.
No mirrors, reflective surfaces, or unsecured lighting are permitted within 30 meters of the chamber.
Description:
SCP-[cannot be classified] is a humanoid entity approximately 5.1 meters tall, with abnormally elongated limbs and pale, translucent skin. Its facial features are mostly undefined except for a wide, humanlike mouth that constantly displays a fixed, exaggerated grin filled with small, uniform teeth.
SCP-[cannot be classified] is invisible in direct light and only becomes partially visible in complete darkness, where its smile and vague outline may appear to observers. It is drawn to individuals who are alone in the dark, particularly those experiencing fear or anxiety.
When an individual perceives SCP-[cannot be classified]'s smile, they become immobilized, often reporting a feeling of being "seen" or "invited." Within 10 to 15 seconds of eye contact, SCP-[cannot be classified] will violently appear beside the subject and remove them from the area. Victims are never found. Security footage always fails during the final moments, usually replaced with static or corrupted data.

Discovery Log:
SCP-[cannot be classified] was discovered in ███████, a small town in Malaysia, following a series of disappearances during winter blackouts. Survivors reported "a mouth smiling in the dark, floating, waiting." A recovery team dispatched to the area lost three members before managing to lure the entity into a transport chamber using sound, darkness.
Note by Dr.███████: "It doesn't stalk you. It waits. It wants you to see it before it comes for you. That smile isn't friendly — it's a warning. Or a promise."
