Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: Currently, the governments of 89 countries have cooperated with the Foundation, passing laws which require hospitals and clinics to send all blood sample results to the Foundation front "Common Pathogen Sequencing." AT which they will be sorted by an automated computer system in order to locate instances of SCP-XXXX by finding several key markers present in their blood. Once an instance is located, MTF Gamma-16 ("Sunlight Warriors") are to be deployed to neutralize instance. High caliber armor-piecing ammunition is to be utilized in order to penetrate an instance's cranial cavity and destroy the brain, as body-shots and standard ammunition are ineffective due to instances' regeneration abilities and defenses. After neutralization, the corpses are to be returned and preserved for further research promptly cremated. If a human is known to have been infected with SCP-XXXX-1, they are to undergo a procedure in order to render them permanently sexually sterile.

Description: SCP-XXXX refers to any human who has been born from parents affected by SCP-XXXX-1. Instances of SCP-XXXX are superficially identical to humans, save for slightly sharpened and elongated canine teeth and abnormally pale skin. However, they possess many internal biological traits vastly different from that of an ordinary human. Their skin appears to be highly sensitive, allowing them to sense air currents generated by nearby moving objects, however their skin can be easily burned by the sun in a matter of minutes, leading them to seek shelter during daytime. They also have eyes capable of viewing objects in full clarity in near complete darkness, this sensitivity makes bright lights incredibly uncomfortable, eventually leading to migraine headaches after prolonged exposure. Incredible feats of strength are possible in every instance due to a much higher muscle fiber density in addition to an unusual ability to voluntary control the production of adrenaline withing their bodies. Instances of SCP-XXXX also appear to lack bone marrow, instead having bones made entirely of an orderly micro-lattice structure, causing them to have a much higher tensile strength and hardness than that of ordinary bones. Due to the lack of bone marrow, instances are incapable of producing normal blood cells, requiring them to drink the blood of others to survive. This is facilitated by their ability to to siphon blood through a branching tract in their esophagus into a specialized organ which appears to store blood cells in high concentrations to be released into the bloodstream to replace dying cells as needed. This specialized organ is also able to produce a type of blood cell unique to SCP-XXXX, these cells are approximately 10 times longer than red blood cells and have an unprecedented ability to locomote due to their internal structure. These cells, in addition to a much faster metabolism, allow instances of SCP-XXXX to regenerate injuries incredibly rapidly, this is achieved through the linkage of specialized blood cells to one another, forming long cellular chains which connect to damaged tissue and pull them together while also acting as a biological scaffold for the new formation of cells. Violent tendencies have been observed within nearly every instance of SCP-XXXX, which appears to be caused by an increased production of testosterone in addition to other differences in brain chemistry.

Studies of captures instances of SCP-XXXX have determines that their maximum life span is approximately 48 years, this is theorized to be due to the high-stress state that composes most of an instance's life.

Once a month, for 5 days, instances produce SCP-XXXX-1 within their salivary glands and will display incredibly violent behavior, attempting to attack and bite anyone nearby, however they will not attempt to fatally would any targets and appear to be focused on spreading SCP-XXXX-1 among as many people as possible. SCP-XXX-1 is a virus which can only replicate itself within the genitals of human subjects. The virus does not spread to any other part of the body, is non-contagious, and does not appear to have any dangerous symptoms. The only know effect of SCP-XXXX-1 is the genetic modification of sex cells within a human, while this does not directly affect an infected individual, their offspring will have a 50 percent chance per parent to be born as an instance of SCP-XXXX.

Addendum: Research is ongoing in order to determine the viability of SCP-XXXX blood cells being used to safely treat human injuries.
