Item #: SCP-XXXX
Object Class: Euclid
Description: SCP-XXXX is 3 meters tall with a dark-blue skin, it is humanoid in shape and anatomically correct with exception to its height. SCP-XXXX has no other bodily features other than two eyes and a mask-like object covering the lower lover half of its face. SCP-XXXX's mask-like object seems to be one of the only fully solid objects on SCP-XXXX with exception to his eyes which emanates an amber glow, while the rest of SCP-XXXX's is liquid-based with the viscosity of honey but doesn't stick to other objects. SCP-XXXX has no known organs or bone structure as of current experimentation. SCP-XXXX has a varying movement speed based on the air pressure around it. Dr.█████ made an equation to measure the speed of SCP-XXXX based on the air pressure, the equation is [DATA OBSOLETE], the equation shows that that higher air pressure makes it slower.
the behavior of SCP-XXXX is more like a regular person with the mask-like and proves to be very conversational and has an attitude similar to a 20-year-old male, and even knows how to use slang terms but will commonly use profanities, but is still obedient to SCP personnel. SCP-XXXX's mask-like object (now will be referred to as "the mask") seems to control the behavior of SCP-XXXX as when the mask is removed SCP-XXXX immediately sends out a large electromagnetic wave that makes communications and security cameras go down for approx 10 minutes, and for the duration of the 10 minutes SCP-XXXX will attack anyone within its line of sight and will only stop trying to attack if the 10 minutes is up even if there are obstructions. after the 10 minutes, the mask will fly at SCP-XXXX with an extreme amount of force in a straight line and will go through any obstruction, once the mask goes back on SCP-XXXX will go back to being docile.
SCP-XXXX's mask has been proven to be impossible or incredibly difficult to remove by personnel or anything other than SCP-XXXX who seems to remove it with relative ease and says it will remove the mask every 20 hours. The mask has an expression made from small and thin elliptical patterns taking the vague shape of a mouth
Special Containment Procedures: Must be contained in a 4x4x5 meter foam-padded room with 10 cm thick aluminum walls and air pressure of 3 atmospheres if the mask is attached and 10 atmospheres if the mask is removed, the chamber should never have any windows. the entrance must have a 3-meter long hallway with reinforced airlock doors that must never go below 4 atmospheres of pressure. MTF has to be tasked to go to SCP-XXXX's containment chamber in case of a breach every 20 hours and will also check for any kind of cracks or way that SCP-XXXX could see the outside of its containment chamber.
Notes:
- SCP-XXXX prefers not to have any kind of permanent photo or video feed of it to be saved in any kind of archive
- despite the lack of organs or any kind of digestive system, SCP-XXXX does have food preferences and tends to be very picky with apparently carrots being it's favorite.
- SCP-XXXX's mask can change expression but this is known to be rare and there are no records of it being witnessed by personnel
- SCP-XXXX has been known to talk about "alternative" facilities that it has supposedly worked at but there is no evidence to that point
Notable Experiments:
Conversational Test - 2/17/97
Subject: D-2976
Procedure: Class-d enters the containment chamber and tries to interview SCP-XXXX with his own questions and try to get information primarily on its origins
Results: the Class-d subject enters the chamber commenting on the air pressure with SCP-XXXX telling the subject that all seems fine, they have a conversation for an hour but then SCP-XXXX takes its mask off disregarding its regular 20 hour period. the rest of the video went to static, along with the previous hour having small parts of visible interference. there are no remains of D-2976 but MTF1 report of hearing yelling inside the containment chamber and some loud slamming despite the padded foam
Insanity Test - 3/28/99
Subject: SCP-XXXX
Procedure: SCP-XXXX gets sent to an isolated room with a subtle yet distinct beep noise at random intervals
Results: SCP-XXXX eventually got annoyed by the noise after an hour of constant playing and after 2 more hours SCP-XXXX made a loud screech loud enough to be heard from outside the facility and the screeching went on for the rest of the test, afterwards, SCP-XXXX shows signs of major exhaustion for a length of 2 days.
