Item #:SCP-4350
Object class:Euclid
Special containment procedures:SCP-4350 was moved to SCP site██ █ days after its abduction and containment. SCP-4350 is contained in a normal humanoid environment walled with enforced steel and lined with a 2ft thick layer of graphene. SCP-4350 must be kept locked inside of its container at all times to prevent the occurrence of a facility breach. No more than 2 Class-D personal are permitted to enter SCP-4350's cell, they are advised to approach SCP-4350 with extreme caution and to not make sudden movements. The entrance to the cell consists of an air-lock type structure with a 10" thick steel door. Class-D personnel and level 4 and above personnel are to enter the lock and make sure that the door is locker behind them to prevent a breach. Once finished both doors must be locked behind those vacating SCP-4350's cell. SCP-4350 is to be relocated to an identical cell once every 2 months.
Description:SCP-4350 is a 2.16m humanoid entity (at full stretch), which has the capability to adjust its own physical appearance to allow its "prey" to believe that it is something it is not. SCP-4350 is able to genetically copy the voice and appearance of any entity that it has recently come into contact with. Its skin appears to be human , tests have been scheduled to identify its material (by Dr. █████ at ██:██)Tests have been cancelled due to a significant change in SCP-4350's behaviour. SCP-4350's head structure is strangely similar to a humans, however it carries no human facial features, besides 2 eye sockets and a mouth. Eyes do not appear to contain any type of optical structure. Its arms are dis-comfortingly out of proportion with the rest of its body reaching a measurement of roughly 1.1m. Its legs are similar reaching a length of roughly 1.4m. SCP-4350's movement is what makes it so unique, it seems to be able to change its direction without its velocity being affected, meaning that it has the potential to travel very fast. SCP-4350 also seems to enter a deranged state of mind during an attack or an attempt to escape, having sudden and unwarned muscle spasms in which it accelerates all over the room at high speeds during this period of time (see video log 4350-a for further detail) all known video footage of SCP-4350 is declared as class 5 confidential material. SCP-4350 has the capability of climbing the walls and moving from one end of the cell to the other at high velocity, whilst showing no signs of energy loss or fatigue. These "moments" are to be referred to as "spasms" in any future references. During the event of an attack, SCP-4350 will somehow identify its victims name and will repeat it until its target is confirmed dead, this voice has a strange "echoing effect" on its victim, which was discovered by Dr. █████ on ██/██/██ at 18:00. If SCP-4350 has an obstacle in its way, or is trying to find a hidden target, it will proceed to have one of its "spasms" until everything in its presence is entirely obliterated, including its target. SCP-4350's method of attack is to impale its target through the upper torso with its blade-like hands. SCP-4350 has been reported to reach speeds of up to ██km/h. It is currently being detained at SCP site ██. Any change in SCP-4350's behaviour is to be reported to level 5 personnel or Dr. █████ immediately.

<Begin log>
Dr. ████: This is SCP log 4350-2, site location ██, and the current time is 16:00. Sir, could you please describe to us exactly what it was that happened?
Witness 1: Uhh, yeah, sure. Ummmmm, well I was out with my friend Marcos, who suggested that we should go and explore some abandoned building or something, and I obviously accepted his suggestion.
Dr. ████: And where exactly was this abandoned site, Mr. ███████?
Witness 1: It was the old factory in █████.
Dr. ████: Please continue.
Witness 1: So we went there, and before we even went in i had this strange, chilling sensation run through my body, like as if my mind was telling me that if we were to go in then we would not come out unharmed or even come out at all. I have never felt like that before, but of course i kept this to myself as I didn't want Marcos to think that i was scared.
Dr. ████: And what happened when you entered the premises?
Witness 1: Well we climbed in through an empty window frame and searched the building for a while, the place was absolutely huge and we didn't exactly want to get lost, just in case. Around 10 minutes after we entered the building we both heard it.
Dr. ████: What exactly was it that you heard Mr. ███████?
Witness 1: Out of absolutely nowhere we heard something call Marcos' name, we both tensed up and stayed quiet in fear of being caught trespassing. Then it called his name again, this time demanding for him not to hide as whatever it was knew we were there.
Dr. ████: And did you?
Witness 1: Oh of course.
Dr. ████: Please proceed.
Witness 1: After it called for the second time and still got no response, it started to call "Marcooooos" continuously, like how your mum would call you to tea, and its voice seemed to echo unnaturally which made Marcos and me freak out. We heard whatever it was growing closer by the second, it was in our room within 2 seconds. Then it stopped, it knew we were in there, and screamed Marcos' name one last time before it went ballistic.
Dr. ████: Please describe exactly what you mean by "It went ballistic".
Witness 1: It started to smash up everything, and I mean everything. It somehow moved all around the room using its arms to destroy all obstacles in its way at unnatural speeds. The way it moved was horrific. Then it found Marcos.
Dr. ████: What did it do to him?
Witness 1: It didn't show any sign of fatigue. It just thrusted its arm through his chest and let him bleed-out, it didn't eat him or anything, almost as if it was doing it out of anger. Anyway, after the thing left the room I tossed myself out of the nearest window and ran for the nearest police station, and that made them think i killed him, which is exactly why I am here.
Dr. ████: Has this event left you with any emotional distress?
Witness 1: All I've heard for the past month of sleep is that thing calling my name. Its horrible to think that it could come for me next.
(*Witness begins to sob*)
Dr. ████: SCP-4350 is due for termination on ██/██/██ at ██:██, witnesses are to be contained until further notice.
