Item #: SCP-XXXX

Object Class: Safe

Special Containment Procedures: [Paragraphs explaining the procedures]

Description: SCP-XXXX is a 19 year old caucasian male, approximately 1.8 metres tall recovered from [REDACTED], Scotland. Subject is slightly underweight, and shows no physical abnormalities. Subject is mostly docile, but will often become temperamental with personnel when being interviewed. Despite this subject has shown to have a sense of humor, often displaying this when using it's ability.

When SCP-XXXX issues a threat to any individual(s) within hearing range, the affected individual(s) will believe that SCP-XXXX is be able to carry out the actions threatened regardless of them being possible or not (this has included a threat to punch a hole in Agent [REDACTED]s heart, and more unusually threatening to unleash an army of rabid [REDACTED] upon Dr. Beaumont).

For an individual to be fully affected by SCP-XXXX however, several conditions must be met. The individual(s) affected must be able to hear and understand the subject. (Individuals who cannot understand English, the subject's first language, will not be affected by threats issued). If an individual is perceiving the subject and is able to hear and understand the threat clearly, the effect will fully activate, leaving the individuals anxious, upset or markedly distraught depending on the severity of the threat.
Most importantly, as described by the subject itself, the threats will only have an effect if it "truly means it", meaning that the subject must understand and believe the threats it makes to be genuine for individuals to be affected.

SCP-XXXX can use threats to control individuals, forcing them to perform actions as a result of the fear of believing the subject being able to carry out the threat should they not comply with it's requests. Testing has shown that the more severe the threat, the stronger the compulsion within affected individuals to perform tasks and actions requested by the subject.
