Prof. Joseph Scorn: SCP-XXXX "The Parasite"

Item #: SCP-XXX

Object Class: Euclid

Special Containment Procedures

SCP-XXX is to be confined within a 32 meter3 cement cellar. Said cellar must have proper ventilation in accordance with District 27's Modified self-sustaining ventilation method (See District 27 Circulatory Blueprint for further details).
Should malfunction occur within SCP-XXX's chamber in regards to ventilation, dispatch all available D-Class personnel in accordance with Foundation-certified HVAC and technicians.


Do not be alarmed if SCP-XXXX appears dead. This is an instinctual trait when in the presence of larger organisms or feels cornered and should be paid no mind. Simply carry on.

SCP-XXX should not be antagonized, teased, or threatened physically while in a docile state. Such provoking behaviour may induce the urge to flee by whatever means necessary. Please maintain a safe, minimum distance of 7 meters from SCP-XXX at all times.


SCP-XXX is most notable for its dry, white, scaling epidermis; giving the entity a strong and calloused exterior shell. The organism's nasal cavity is made up of two large holes in the front of the head. The oral cavity is lined with uneven teeth resembling that of sewing needles.

In order to eat, SCP-XXX must shred its source of nutrients with its claws into a loose pulp as its teeth are not capable of chewing and ripping apart mass, and thus, uses them strictly as a second line of defence against potential predators. However, the entity prefers to avoid confrontation if at all possible.

While anthropomorphic in appearance, SCP-XXX shares many characteristic traits to an ursidae in that it is four-legged but is capable of standing upright if intimidated by opposing threats. It is an omnivorous and opportunistic feeder, and has a strong sense of smell. SCP-XXX's fingers are tipped with finely sharpened black claws which extend to about 4 centimeters in length. The entity also is incapable of giving live birth as crucial genitalia and organs are absent from the creature, though, odd, tangerine-colored lumps of synovial pockets line the underside of the creature. This is assumed to assist with crawling into tight spaces.

SCP-XXX is, upon reaching the adolescence stage, 1.2 meters in height and length and weighs roughly 432 ounces. The bone structure of the organism is comprised of fontanelle with calcium plating, rather than traditional bone marrow; allowing for SCP-XXX's thoracic cage to collapse and condense, enabling it to fit into environmental safe havens (Snake dens, creases in rocks and cliffs, etc.) to escape predators and environmental danger.

SCP-XXX's lifespan has recently been discovered to be 14-17 human years. D-class personnel are to be used as hosts and initial food sources for the next generation.

The entity's flaking callouses acts as a sort of pollen in that it detaches from the body in dust-like amounts (SCP-XXX-1). Should SCP-XXX-1 be inhaled, upon contact with a hydrogen-oxygen compound, it becomes a protein and has varying effects.
Should it be inhaled by homosapiens, SCP-XXX-1 attacks the reproductive organelles of the newfound host and will begin mitosis within males while merging with pre-existing sperm, and fetal development within females.
If a woman were impregnated with infected sperm, SCP-XXX-1 will develop alongside the fetus, using it as a source of nutrients as it develops. If SCP-XXX-1 is the initial inhabitant of the uterus, it will use its host for the same purpose by tearing the dermis of the organism in order to feed itself.

(SCP-XXX-1 does not have the same effect on other creatures as it's DNA is unable to bond with non-human entities in the sense of reproduction. (See DL-2-XXX.))

If SCP-XXX were to come in contact with liquid, the epidermal shell would dissolve, exposing internal organs and the skeletal structure. (Refer to DL-1-XXX for further information.)

Given proper circumstances, SCP-XXX's development within the uterus takes only four-to-five months and will voluntarily crawl out of the vulva once fully developed — killing the female host during the process and proceeding to devour it and any other food sources nearby.



SCP-XXX's epidermal shell can take up to 14 months to fully develop after birth. It is a rapid mutation in the epidermal layer that causes the excessive callouses to grow on the creature's body.

If the shell is dissolved, the entity's thin epidermal layer is exposed; revealing a pale, slimy exterior similar to that of when it crawls out from a woman's vulva in the infantile stages.

The first incident of SCP-XXX's recorded discovery was at a small home in Oklahoma when one had crawled under the foundation of a two-story home to seek out shelter from the sun. The man living there found it and attempted to shoot it. The bullet deflected by the frontal shield, alarming the creature and resulting in ██████████'s mutilation.

The creature is known to seek out human civilization during the end of its life in an attempt to find a host for the future generation. Generally, the entity will stand upright and howl when it smells human flesh as a way to hopefully gain the attention of nearby men, then will violently shake its body to release SCP-XXX-1 into the air.

In DL-3-XXX, SCP-XXX gives chase if a suitable host attempts to run. (See DL-3-XXX.)

If SCP-XXX manages to escape containment, and are too far from equipment used to handle SCP-XXX properly, stay silent and remain still until SCP-XXX finishes inspecting you.

The letter was torn in some areas.

Addendum #2

Dr. Carpathia was found with a large tumorous infection in his right arm. A deep purple coloration under the skin stemmed from the bite received July 20th, ████ in the central portion of the humerus, extending to the central portion of the lateral pectoral muscle and kidney.

Pathologist Dr. Burner confirmed after extensive study the bite of SCP-XXX caused sever infection in the dermis which soon began eating away at the veins, working its way to the heart within a matter of hours; internal bleeding ensuing as the infection corrupted the liver of the researcher.
