Item #: SCP-6357
Object Class: Euclid
Special Containment Procedures: SCP-6357 is to be kept in a 15x15x15m reinforced steel box kept floating by reinforced steel cables with a minimum of 0.61 meters in diameter. The box should have multiple cameras covering the box's inner and outer walls. There should be a single airlock between each the outside and inside of the box. The Chamber should not be connected to any other SCP subjects in a 1.5 Kilometer radius. Only D-Class Personnel are permitted to enter SCP-6357's containment chamber for testing due to incident SCP-6357-1-A where a scientist entered to try and communicate with the subject. [DATA EXPUNGED]
Description: SCP-6357 is primarily called "The Squinter" by Facility Guards monitoring it. The subject, when first found, appeared to be a young man with blond hair. Further testing revealed that The Subject takes the form of the last victim they killed. The subject doesn't actually take the form of them, though. It just tricks your mind that he looks like them. The subject appears to be completely normal. That is, until, while looking at The Subject, you strain your eyes, or squint. After this, the Subject starts morphing into a beast. Its face splits in two, revealing a large mouth with unfathomable amounts of teeth. He proceeds to tear the person who "disrespected"(now known as SCP-6357-1) them into very fine slices. Afterwards, the subject proceeds to [REDACTED]. The Subject then flips into a state of rage, attacking any sentient creatures in a kilometer radius, running at a speed of around ███-Kilometers per hour. After a time of around 2 hours, the subject calms down and returns to the attack origin, now calm.
Addendum: This is a recorded and then typed interview between the Scientist who monitors SCP-6357 and the Mobile Task Force commander who captured it
Dr. ██████: Good afternoon, sir. I appreciate that you could take some time off to talk with me.
MTF Commander: Always a pleasure to talk with anyone apart from my own platoon. Besides, I've been waiting for this as well.
Dr. ██████: So I've been told to call you here to describe the events of what happened that day.
MTF Commander: I can't exactly say that I'm completely comfortable discussing the topic, but I don't think I have a say in the matter.
Dr. ██████: That's unfortunately true. Let's just get this over with then, shall we?
MTF Commander: The O5 council told us that there was potentially anomalous behavior over in ██████, Montana. A lot of the time, these notes turn out to be false alarms, but we do get truly anomalous behavior sometimes. I really wish this was one of these times. We landed at the nearest possible flat surface. A standard SCP containment vehicle was waiting for us there. We get ready to bag the subject, when the thing pulls a fucking flashlight on some of our boys. Obviously, they squint, causing the whole thing to go down.
Dr. ██████: Wait, he knows his abilities? That's very unnerving, that is. Why didn't you tell us this before?
MTF Commander: Well, first, because I've never had the chance, and Second, I thought you already knew.
Dr. ██████: Okay, anyways, continue.
MTF Commander: he changes into this thing, and rips the boys who saw him a new one. No matter what I try, I can't get that image out of my head. The ones who weren't looking, myself included, get in that chopper, and book it. We made it pretty far. That thing was so damn fast that he had to slow down to keep up with the chopper. After a while in the air, for what seemed like a lifetime, the creature returned the the origins of the murders. We successfully got him this time, and we didn't look back. What was left back there was for the cleaning crew to deal with.
Dr. ██████: Thank you, sir. I'm sorry you had to go through with this.
MTF Commander: ah, its fine. I lived through it, so talking about it isn't as nearly as bad. Have a nice day, Doctor.
Dr. ██████: you, too.
