██ CLASSIFIED ██
Level 4 clearance required

Item #: SCP-035 · Object Class: Keter

Special Containment Procedures:
SCP-035 is kept sealed within a hermetically sealed glass cube no less than 10 centimeters thick, housed inside a secondary chamber lined with steel and lead plates. Direct physical contact is strictly forbidden; all maintenance must be conducted via remote robotic surrogates.
Corrosive black runoff must be continuously drained into neutralization tanks. Any personnel within fifty (50) meters must undergo psychological evaluation, and direct visual contact is prohibited without telepathic shielding. Anyone showing fascination or obedience toward the entity is to be detained and administered Class-A amnestics immediately.

Description:
A white porcelain comedy mask that periodically shifts into tragedy. A thick, highly corrosive black fluid continuously seeps from the eye and mouth openings, rapidly decaying and dissolving all surrounding physical matter.
SCP-035 emits a subconscious telepathic aura compelling nearby individuals to place it upon their face. Once placed on a humanoid subject, the host's brain waves cease instantly and SCP-035 assumes full motor and vocal control, causing the host body to rot into necrosis within days.
SCP-035 displays genius-level intellect, extreme charisma, and profound manipulative capability, regularly attempting to psychologically break researchers and coerce site personnel into facilitating its release.

Log One: ██/██/████
Interview session. Dr. ██████ initiates a scheduled audio interview with SCP-035 while it occupies a decaying host. Through the reinforced observation window, SCP-035 tilts its head, shifts into an exaggerated grin, and begins addressing Dr. ██████ directly, speaking about intimate personal memories not recorded in any Foundation file.

Log Two: ██/██/████
Drainage maintenance. D-████ is equipped with standard hazard gear and ordered inside the containment chamber to clear corrosive sludge from the floor grates. The heavy airlock slams shut and locks from the outside. Inside the glass cube, the mask shifts to tragedy, and a persuasive, low whisper begins echoing directly inside D-████'s head.

Log Three: ██/██/████
Containment breach. The glass cube shatters under acidic stress, flooding Sector-04 with corrosive fluid. Power cuts across the wing, the primary blast doors jam halfway open, and black fluid tentacles begin dragging unresponsive personnel into the dark toward the free entity.

Addendum:
SCP-035 was reclassified from Euclid to Keter following repeated breaches and its ability to weaponize acidic runoff into mobile constructs. Cross-testing with other sentient anomalies is strictly prohibited.
