SCP-XXXX-7 prior to containment, preparing to sedate prey provided by MTF Iota-9.

Status: Work in Progress

Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX instances are retained in Cell 291 through 297, 299, and 301 within Sector-7 of Armed Containment Area-247. Containment chambers are 12 m x 12 m x 2.5 m concrete enclosures and are to contain a maximum of 7 SCP-XXXX instances. Chamber interiors are to be monitored at all times via recessed infrared cameras. Respective chambers may only be entered if all instances within the enclosure are heavily sedated, provided each instance has not reached Stage 2 of their breakdown cycle. Personnel are to maintain a distance of at least 1 m from each instance. If an instance is to reach Stage 2 of its breakdown cycle, all personnel within the chamber are to be evacuated immediately.

Should an instance near completion of its breakdown cycle, a single sus scrofa domesticus1 is to be led into and sealed within the chamber. The SCP-XXXX instance must completely assimilate the provided prey before personnel are allowed within the cell.

Sightings of potential SCP-XXXX instances are to be investigated immediately, and Mobile Task Force Iota-9 ("Oceania Takedown") is to be dispatched when an instance's presence has been confirmed. Iota-9 is to ensure an instance has not began its breakdown cycle before containment procedures are initiated. Should an instance have begun its breakdown cycle, a sus scrofa domesticus is to be dispatched within its vicinity once Stage 2 is reached and all MTF agents present are to maintain a distance of at least 70 m until the provided animal is assimilated.

Description: SCP-XXXX are a reptilian-esque species of quadrupedal predators indigenous to the southern coastline of New Zealand. SCP-XXXX average 2.4 meters on all fours when measured from the head to the abdomen2 and on average weigh 225 kg. SCP-XXXX are nearsighted and are unable to easily distinguish anything more than 2 meters in front of them, and instead rely on pit glands to detect infrared radiation in order to locate prey. Despite SCP-XXXX having mouths, instances do not require consumption, and are used exclusively for biting and fueling its prey's respiratory system. Six 2 cm fangs line the front of the upper and lower jaws, each laced with a tranquilizing agent with similar effects to that of xylazine. Bites from SCP-XXXX cause little injury and have never been recorded as fatal.

SCP-XXXX instances typically reside alone3 in lightly forested regions. However, SCP-XXXX appear to be content in sharing containment chambers with other instances and express minimal hostility. Interspecies assimilation between SCP-XXXX has never been recorded.

SCP-XXXX live off of other organisms, and will assimilate most animals, presuming they can provide enough sustenance. SCP-XXXX have thin curved trays that protrude from their lumbar and are capable of extending and warping to fit the organism they intend to assimilate. Upon the complete sedation of a chosen host, an instance will dislodge its tray to wrap around the animal; the trays will then re-attach with its back4. SCP-XXXX instances will release barbiturates into their prey's bloodstream, effectively rendering it in a state of locked-in syndrome. The anomalies are capable of producing an enzyme that both significantly slows down and supplements their prey's digestive system, capable of sustaining it for several months. SCP-XXXX will bond its faux respiratory and excretory systems with its host's, providing oxygen and excreting waste for it. In turn, SCP-XXXX will use the bodies energy to power its own circulatory system.

The host will eventually expire, typically 8 to 9 months after an SCP-XXXX instance bonds with it5. The anomaly will then begin a breakdown process, converting the remains into more energy that it will live off of until another host can be found.
Stage 1: Hydrochloric acid is released into the chamber created by the trays. The body will slowly break down, taking between 6 and 7 days to be completely dissolved.
Stage 2: The energy provided by the breakdown will slowly be absorbed by the instance. The instance will typically begin hunting at this point, and will often bite the prey it has selected to prevent it from leaving its vicinity. The trays will unravel from each other and lock back into their original position upon completing the absorption process.
Stage 3: The anomaly will begin assimilating the recently sedated animal as described above. If a new host cannot be found, its circulatory system will slow down and inevitably cease to function within 40 minutes.

Item #: SCP-XXXX

Object Class: Euclid Safe Euclid

Special Containment Procedures: SCP-XXXX is permitted to roam the facilities of Site-98 in the company of MTF unit Echo-7, as long as the outer ring is not exited. The anomaly may only exit the outer ring with level 4 clearance or higher. Power is to be kept running at all times, with three sets of back-up generators on stand by at all times. In the event of the complete failure of the lighting system, the outer ring is to be completely locked down until power can be restored. Any failure in lighting systems or equipment within the Unit is to be repaired immediately.

All personnel within the outer ring must carry a light source. No section of the interior of the outer ring is to have any dark patches of light whatsoever, and all lights are to be tamper- proof. Requests for items or an escort to a specific room may be obliged, as long as it remains within given boundaries.

SCP-XXXX is to be placed in a concrete containment chamber located in the center of the Outer Ring if the anomaly expresses any unusual activity. Any such activity is to be reported to Site personnel immediately. SCP-XXXX's mane is to be trimmed every 2 weeks.

Description: SCP-XXXX is a quadrupedal/bipedal being with a height of 2.1 m and a mass of 432.8kg. Its outer layer of skin is of a grey and green coloration, containing traces of several rock compounds (i.e. nickel, iron) as well as organic matter similar to that of plants. This matter contains large amounts of chlorophyll, of which it uses to absorb energy from any provided light source. It has a conical head, similar in shape to those of reptiles. A mane of vines is present on its back, growing from the neck to the bottom of its back. These vines will continue to grow indefinitely until severed. SCP-XXXX has never appeared to shed these vines. Two eyes are present on opposite sides of the head, often fluctuating in coloration, seemingly capable of covering a majority of the color spectrum. SCP-XXXX does have a mouth, although no teeth or tongue of any sort is present within it, and seems to serve the sole purpose of utilizing vocal cords.

SCP-XXXX appears to express a split personality. When in the presence of a bright light source, the anomaly is friendly and has never attempted to harm personnel or damage equipment or other such objects. The entity often seems to enjoy reading most literature. SCP-XXXX will often request to watch films, although it will occasionally become bored and ask that the film be turned off. The entity is often friendly if not helpful to foundation personnel, offering to assist personnel on tasks, such as carrying heavy equipment or even solving problems.

However, if SCP-XXXX is exposed to dimly lit or completely dark areas, the entity's personality will completely change. The anomaly will quickly become violent and begin destroying much of its surrounding terrain if proper reinforcing is not applied. It will often proceed to attack anything that moves, including inanimate objects (i.e. a stress ball that slips off a desk). It will, on extremely rare occasions, tear off the vines on its main and begin mutilating itself, although the skin heals fairly quickly. The vines, however, can take a long period of time to regrow.
In this hostile state, SCP-XXXX will attempt to avoid all major light sources, often recoiling from bright flashlights and avoiding lit areas. This also works in reverse- in the non-violent state, the anomaly will avoid dark patches altogether. If SCP-XXXX believes a room is to dark (even if it could not trigger its enraged state) it will actively avoid the room. SCP-XXXX does not seem to be conscious of the fact that its hostile personality exists.
