Item #: SCP-4224
Object Class: Euclid
Special Containment Procedures: [Paragraphs explaini
Description: SCP-4224 is a sort of entity that takes the silhouette of a human and is in some kind of way a shadow. Even though it is a shadow, 4224 is upright and not 2D on a surface, but it is not 3D either. What I mean by that is that from whichever side you are observing it, it will seem like you are looking at it’s “face” and will seem like it is looking straight at you even though it’s attention might be captivated by something else. This particularity’s purpose is believed to be to inspire fear, which is the usual emotion felt when someone stares at you intensely without end.
4224 has no reaction to any experiments we exposed it to. Although, 4224 randomly (but often) bursts the walls and doors of it containment cell open then runs off at high speed (we have been able to measure 150 km/h to 200 km/h) to a street mugging (or rape, murder,…) , then slashes the mugger’s body with it’s bare “hands” 4 times, two to the chest and two to the head than rips the mugger’s hart out and dissolving it with it’s “hands” corrosive properties, then proceeds to the mugged civilian, does exactly the same attack leaving the hearts in a blood poodle on the floor. 4224 has not been seen detecting and rushing to a street crime over 15 km away.
4224 appears to possess some sort of divination power or a special sense that allows it to know when a street crime is going to happen in a 15 km radius, we believe this because 4224 usually gets startled and starts running to a street crime minutes before the crime is actually going to happen (depending on the distance it might run even before then).
