Object Class: Euclid
Special Containment Procedures: SCP-XXXXs containment procedure is highly unique due to both its role within the foundation as well as its capabilities. SCP-XXXX is to be kept within a standard sealed living quarters that has been modified to be air tight. In the even of an emergency all vents can be closed and oxygen can be purged from the room untill subject loses consciousness. Open request subject may be allotted a specific time for outdoor activities or social interactions up to twice per week. However SCP-XXXX will be required to weird a puncture proof hazmat suit when leaving containment, which itself has the capability to cut off the oxygen supply of the wearer. SCP-XXXX is not to be in physical proximity to any foundation members of class B or higher without specific permission of a higher ranking individual. Though SCP-XXXX is allowed limited access to database entries in order to provide its own insight into further research, it is under no circumstances to be allowed access to either its own file or the files regarding other biological anomalies. Permission from an O5 council member is required to bypass this rule and permission from at least 3 O5 council members is required to allow SCP-XXXX physical access to any biological anomaly
Description: What appears to be approximately 3 liters of seemingly human blood. Chemically indistinguishable from that of a human being. Is both sapient and able to move and alter its shape through unknown means as well as harden into a dense material similar to instances of SCP-578-1. SCP-XXXX is capable of inhabiting the body of any organism with a circulatory system similar to that of humans. SCP-XXXX Forces its way into the subjects body through any form of cut, wound or other abrasion, causing the host to rapidly expel their own blood through the skin until normal blood pressure is achieved, which has been described by the current host and mildly painful. SCP-XXXX is highly intelligent and is capable of speech when inside a human host, however the voice produced is notably raspy and of higher pitch than that of the host. SCP-XXXX is capable of controlling the body of its host however most often allows host to remain in control. SCP-XXXX is currently inhabiting the body of field agent Jerrod Branson (SCP-XXXX-2) after the botched capture attempt of the previous host (SCP-XXXX-1) on June 27th 18__. Due to the near complete destruction of Branson's heart in said incident he cannot survive without SCP-XXXX within him to manually circulate his blood. SCP-XXXX is highly co-operative and enjoys social interaction with both branson and others. Psychological testing found SCP-XXXX to display low-level sociopathic traits, often making insensitive comments regarding the deceased or traumatized. (side note: SCP-XXXX seemingly identifies as male)
