Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX is classified in the medical world as Sarcoma Cardiac Prognosis. Any patients diagnosed with the condition are referred to Foundation cover fronts for treatment. Instances of SCP-XXXX are to be immediately detained, and stored in a standard humanoid containment room. SCP-XXXX is to be kept in a medically induced coma and fed intravenously for the comfort of the individual currently manifesting the phenomenon.

Description: SCP-XXXX is currently affecting ████ █████, following the death of ██████ ███. SCP-XXXX is a phenomenon occurring in a single individual somewhere in the United States that causes the individual manifesting the phenomenon to contain instances of SCP-XXXX-1 and SCP-XXXX-2, and a version of Document SCP-XXXX. SCP-XXXX-1 and SCP-XXXX-2 will develop in an individual over a period of two to for weeks. After this point, attacks will begin. Should SCP-XXXX perish for any reason, the phenomenon will relocate to a separate individual. While no pattern has been found as to who the next individual will be3, SCP-XXXX consistently perish on dates outlined in their instance of Document SCP-XXXX.

SCP-XXXX-1 is the collective name for a series of organs of various shapes, sizes, and functions that manifest in SCP-XXXX. Instances are fully integrated into the circulatory and nervous systems of SCP-XXXX, and as such surgical removal is ill advised. SCP-XXXX-1 can be divided into several major subcategories based on location and production.

SCP-XXXX-2 is the collective classification for a series of pre-malignant tumors most closely resembling lipoblastomatosis. Instances are identified by their superficial resemblance to a note on the Western Music Scale. SCP-XXXX-2 primarily manifest in the torso of SCP-XXXX, and the locations of SCP-XXXX-2 are consistent in each instance of SCP-XXXX. Individuals infected with SCP-XXXX-2 report hearing constant vocalizations commonly likened to the sound of a human performing vocal exercises. Removal of any instance of SCP-XXXX-2 results in the tumors producing vocalizations akin to a human screaming. A new instance of SCP-XXXX-2 will grow to replace the removed instance.

Periodically, on dates outlined in Document SCP-XXXX, SCP-XXXX will enter a state of "attack." During these states, SCP-XXXX's heart will enter into an irregular cardiac arrest. Instances of SCP-XXXX-1 will become active during these attacks, and instances of SCP-XXXX-2 have been noted to make slight movements, and produce tones of various pitches. This state will last for exactly 118 minutes, with a 20 minute period of inactivity between the 57th and 77th minutes. These attacks will occur on dates outlined in Internal monitoring of SCP-XXXX shows that the beats of the heart are consistent each attack, as are the movements of all instances of SCP-XXXX-1 and SCP-XXXX-2.

SCP-XXXX-1 Designation Further Information
SCP-XXXX-1a Instances of SCP-XXXX-1a form in clusters primarily in the head and upper torso of SCP-XXXX (with the exception of ≤2 instances located in the feet). SCP-XXXX will anchor themselves to nearby bones and possess the ability to swivel themselves, and will target instances of SCP-XXXX-2. SCP-XXXX-1a possess bioluminescence of varying colors. No purpose has been identified.
SCP-XXXX-1b Instances of SCP-XXXX-1b are located within the ribcage, in the area immediately surrounding the heart. SCP-XXXX-1b are identified by the presence of stringy, segmented strips of ligament that vibrate as the main body of the organ beats. No purpose has been identified.
SCP-XXXX-1c Instances of SCP-XXXX-1c are located within the ribcage, connected to the lungs. SCP-XXXX-1c are hollow, tubular bodies that are either heavily twisted pathways to a single hole. 60% of instances of SCP-XXXX-1c possess additional holes along the main body of the organ, which appear to be covered in flaps that open and close of their own vocation. Air is pumped through the lungs and out of SCP-XXXX-1c.
SCP-XXXX-1d Instances of SCP-XXXX-1d are interspersed throughout SCP-XXXX. All instances appear to be hollow, and are connected via the nervous system directly to instances of SCP-XXXX-2. During an attack state, instances SCP-XXXX-1d will mirror the movements of SCP-XXXX-2, albeit much more violently. Believed to possibly be some sort of amplifier for the effects of SCP-XXXX-2 during attacks.
SCP-XXXX-1e SCP-XXXX-1e is the classification for two layers of wrinkled tissue that surround the ribcage of SCP-XXXX. SCP-XXXX-1e are able to contract and expand themselves horizontally along the ribcage, permeating around any obstacles to obscure the ribcage. SCP-XXXX-1e remains closed around the ribcage unless SCP-XXXX-2 is in the active portion of an attack phase.


A melanin imbalance causes the darkening of the skin on the stomach of SCP-XXXX, causing the formation of a message referred to as Document-XXXX. The content of Document-XXXX has been consistent on each instance of SCP-XXXX with the exception of the lines referring to dates and location. The date The following is a sample version of the document transcribed from ████ █████, a former SCP-XXXX.
