Object Class: Euclid

Special Containment Procedures: SCP-XXXX is to be contained within a holding cell. Cameras will monitor the subject at all times, and must be manned twenty-four (24) hours a day. Following injury to SCP-XXXX-2, resulting in three (3) confirmed casualties, nourishment will be carried out twice per day through normal masticatory means. Under no circumstances is SCP-XXXX to be allowed to come in contact with personnel or other sentient objects. Transportation or manipulation of SCP-XXXX is to be achieved through mechanical means. In the event of a security breach, personnel participating in re-containment are to be quarantined until psychological testing is administered.

Description: SCP-XXXX is composed of two (2) entities: an inorganic sentient being (SCP-XXXX-1) and a male human child (SCP-XXXX-2).

SCP-XXXX-1 is a sentient entity which resides within the frontal lobe of SCP-XXXX-2. While SCP-XXXX-1 exhibits the ability to infiltrate the cerebrum of personnel that its host comes into contact with, it appears to favor SCP-XXXX-2. SCP-XXXX-1 typically coexists with SCP-XXXX-2; however, it retains the ability to forcefully obtain complete control of its host for limited amounts of time. SCP-XXXX-1 can mimic the mannerisms of its host as well as access its memories. Due to its inherent abilities, detection of SCP-XXXX-1 within afflicted personnel is nearly impossible. Removal of SCP-XXXX-1 from afflicted personnel causes an immediate decrease in higher brain function. This is most dramatically seen in SCP-XXXX-2.

SCP-XXXX-2 is an Asian male three (3) years of age, with black hair and black eyes. Subject is .84 meters tall and weighs 15 kilograms. SCP-XXXX-2 does not appear to have extraordinary physical abilities. While coexisting with SCP-XXXX-1, subject displays heightened intellect, capable of utilizing a sophisticated vocabulary as well as completing advanced logic puzzles. SCP-XXXX-2 seems to be able to communicate nonverbally with the entity; however, SCP-XXXX-2 has been observed having audible conversations with itself. Any harm inflicted onto SCP-XXXX-2 causes malfunction of machinery and afflicts surrounding personnel with SCP-XXXX-1’s effects. Brain function ceases in selected areas of the brain. Typically, the frontal lobe or temporal lobe is affected; however, the brain stem may be afflicted, resulting in death.
