One of the first images to capture SCP-XXXX, before any distortion. The entity is seen to be facing the opposite direction.
Item #: SCP-XXXX
Object Class: Euclid Keter
Special Containment Procedures: SCP-XXXX is kept within site-207, contained within a large containment chamber with 7 meter high ceiling and a window reinforced observation window, 6 meters up
on the eastern wall for researchers to take notes on its behaviour and to monitor any unusual activity. SCP-XXXX is carnivorous and is to be fed a live large black pig that weighs at least 330kg, on a weekly basis. If the pig isn't supplied to the entity it could risk a containment breach. After eating, 3 janitorial staff are to be assigned to clean up any mess and are not to interact with SCP-XXXX. SCP-XXXX doesn't show the ability excrete despite its requirements for nutrients. No fewer than 4 6 armed security team are to be within SCP-XXXX premises at all times, monitoring SCP-XXXX 24/7. The guards are to have shifts of 2 hours and must take a dose of painkillers before entering the area. A psychological evaluation is to be performed —once-twice per month onto SCP-XXXX to make sure the entity doesn’t show any chaotic signs of escape or unnecessary violence. SCP-XXXX would make persuasive requests to turn off the lights. All requests are to be denied, any researcher that attempts to comply are to be immediately apprehended and if persistent are to be suspended. If any lights within the site start to show signs of failure, such as flickering, they are to be reported to the site manager. All offices and chambers near SCP-XXXX containment are to be padded on all edges, and no sharp objects are allowed. Any personnel entering near the containment cell are to have a quick evaluation if they experienced any nociceptive or neurological pain. If not, they'd be given a permission pass to show to the security guards allowing entry. If so, are not to be allowed within the premises near the chamber. Due to the normality of individuals experiencing nociceptive pain, personnel are only allowed 20 minutes at a time within SCP-XXXX containment chamber to decrease the risk of a containment breach. SCP-XXXX must be sedated when being transported to different locations.
Description: SCP-XXXX is a severely emaciated and elongated humanoid entity standing at approximately 5.8 meters in height. Arms measuring at 4.8 meters long on each arm and shows extreme flexibility throughout all muscle joints, allowing SCP-XXXX to perform postures that is not humanly possible. Skin resembles fabric, that of a black skin-tight suit that dancers/performers wear. Despite SCP-XXXX's skin to be made of fabric, the entity has been recorded to climb vertical surfaces with ease. The average crawling speed has been recorded at 82 km/h.
SCP-XXXX doesn't respond to any form of physical pain having a complex root of nerves around the body. The entities' skeletal structure is strongly resistant to any forms of amputation, as attempts to amputate SCP-XXXX prove to be unsuccessful. Any physical damage to the entity has been observed to rapidly regenerate in the course between one minute to twenty minutes depending on the severity of the wound.
Addendum XXXX-01: Discovery
The institution where SCP-XXXX was first discovered by the foundation.
SCP-XXXX was discovered within ██████ █████ mental institution, Los Angeles after reports of a 'tall figure that disappeared into the night' was spotted by several eyewitnesses in around an abandoned mental institution. Following the dispatch of MTF Omega-29 ("Creepers"), the task force reported to hear screams in the institution, deep inside. The screams were followed by begs and apologies but no mercy was shown as the screams got louder. When SCP-XXXX was confronted, it caused the fatalities of 3 personnel. The MTF units guards was up due to the attack but when SCP-XXXX calmed down it approached the unit calmly and went into foundation custody on 16/09/20██. Source of the screams was a civilian, whose corpse was found with eyes ████, mouth █████, all teeth were █████, fingers and toes were violently ██████, and lying in a pool of his own excrement and blood.
Sweep of the institution revealed:
- 17, corpses of initially missing civilians, and some seemed to have been feasted upon.
- 137, corpses of different small animals including, squirrels, chickens, baby creatures, etc.
- An empty notebook, except for the last page that showed the text "We deserved this."
- A ritualistic pentagram located in one of the cells with satanic symbols around it.
- (It is thought that these symbols tell how SCP-XXXX was created, however, deciphering the symbols was difficult has they have never been seen before in human history.)
- Organic matter such as teeth, body fibres, and blood that were be able to identify 14 other victims, however, there is predicted to be more victims.
Addendum XXXX-02: Recall Protocol 72-49-C - 'Weakling'
These following re-containment procedures will occur if SCP-XXXX breach containment:
- Any personnel with a level 1 security clearance are to enter SCP-XXXX containment chamber and are to flip the lever labelled 'Weakling'. All researchers are recommended to leave the site or hide in safe-rooms if the first option hadn't arised. The switch will set the site power system to a powered back-up generator that causes all the lights within the facility to brighten 30% more. A signal for Recall Protocol 72-49-C - 'Weakling' has just begun.
- 4 D-class personnel will be dispatched wearing a modified shock-collar around their neck with a location tracker inside of each collar that will insinute a swift painful sting every 30 seconds. The shock collar will immediately induce a shock when it detects a great electromagnetic force and will deactivate. When one collar deactivates it'll send out a signal for all other collars to detonate.
- D-class would be spread across the entire site until one gets the attention of SCP-XXXX and begins the hunting phase.
- When one collar deactivates, it'll alarm Surface Team Lemur-709-A to take a dose of painkillers, enter the facility and track down the deactivated collar, as it'll lead to SCP-XXXX whereabouts.
- When visual has been made with SCP-XXXX, 2 scenarios may occur:
- SCP-XXXX would've terminated the D-class and is either torturing the subject or already wandering around its kill.
- SCP-XXXX is still hunting the D-class personnel. When this occurs, Surface Team should terminate D-class on-sight which will bring SCP-XXXX to a halt.
- SCP-XXXX should calm from its triggered state and would comply with foundation staff.
- SCP-XXXX is to be sedated on-sight, only if its in its docile state.
- SCP-XXXX should be kept in a temporary containment cell while janitorial staff are to clean up any mess left behind thoroughly throughout the whole site.
Any personnel caught trying to aid SCP-XXXX in escaping or attempting to breach the site while in lockdown will cause immediate termination.
