Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: Due to the nature of SCP-XXXX, it cannot be contained effectively.
Instead, large population centers are to be monitored on a weekly basis by Foundation personnel in order to locate and apprehend any instances of SCP-XXXX-1. Instances of SCP-XXXX-1 are to be held in a standard containment cell under moderate sedation at all times.
The Foundation has established an agreement with the FBI's Unusual Incidents Unit in order to monitor and detain any instances of SCP-XXXX-1
Description: SCP-XXXX is a trans-dimensional, slightly humanoid figure resembling an adult male with the head of a black goat. The figure is generally described as being significantly taller than any known human, with estimated measurements ranging from 3 to 5 meters. SCP-XXXX is said to have major effects on the mental state of those it comes in contact with. Due to its ability to affect a person's perception of reality, SCP-XXXX has been classified as a potent cognitohazard by the Foundation, and its containment has been listed as high priority.
According to several tests run by Dr. ████ at Site-██, SCP-XXXX does not appear to be a biological entity, and is actually invisible to the naked eye by anyone except those affected by SCP-XXXX's anomalous properties. Those affected by these properties have been thusly named SCP-XXXX-1.
SCP-XXXX-1 is any person affected by the anomalous properties of SCP-XXXX; typically an adult. Instances of SCP-XXXX-1 have been observed to have violent tendencies, and upon medical examinations of their brains and medical records, almost always have some form of psychopathic tendencies or borderline personality disorders. These mental instabilities mean that instances of SCP-XXXX-1 will be extremely unpredictable in nature, and should be treated with the utmost caution when in contact with Foundation Personnel.
Addendum 1: An interview with Subject-████, a homicide convict detained by the UIU. Conducted by Dr. Richards.
Dr. Richards: Hello. My name is Dr. Richards, and I am here today to-
Subject: I know what you're here to do. You wanna pick my brain and try to "understand" me. Well, you can't. You never will.
Dr. Richards: Well, I'd certainly like to try. I just want to ask a few questions.
Subject: I don't need to justify anything to you! She deserved what she got! I don't expect you to understand, but she did! She wasn't the person they all thought she was!
Dr. Richards: Who wasn't? Your wife, Lauren?
Subject: Don't speak her name! After what she did, she hasn't earned that.
Dr. Richards: And what did she do, exactly?
Subject: Are you kidding? When your guys came in and grabbed me, she had just finished butchering the kids. God, she just pulled them from their beds and…started slicing them up. I couldn't let her get away with that!
Dr. Richards: Your kids? You mean, ████ and ████?
Subject: Yes. God, they were so innocent. ████ had just had a birthday the week before…
Dr. Richards: Well, some official FBI records indicate that your two children, ████ and ████, are currently still alive. And quite traumatized, I might add.
Subject: What? No, there must be a mistake, I saw her murder them! I watched it happen! That's why I had to stop it. Stop their suffering. Avenge them.
Dr. Richards: The only body recovered from the scene was that of your wife, Lauren, who was discovered with multiple stab wounds in the abdominal region.
Subject: Oh, my god. That can't be true. What have I done? WHAT DID I DO?!
Subject began to bang his head on the table violently.
Subject: IT WAS YOU! YOU MADE ME SEE HER! YOU MADE ME DO IT! GET OUT OF MY HEAD! THIS ISN'T WHO I AM!
Several guards were sent into the room to detain the subject, who protested violently, begging for them to shoot him instead, which they refused.
