**Item #:** SCP-XXXX
**Object Class:** Keter
**Special Containment Procedures:** SCP-XXXX is currently considered as uncontained by current foundation. All attempts to physically locate SCP-XXXX have resulted in failed pursuit or personnel casualties. Remote surveil via satellites imagery and unmanned aerial vehicles is the current primary monitoring method. Foundation embedded assets are to suppress all civilian media coverage and forensic evidence associated with SCP-XXXX incidents. Direct contact with SCP-XXXX is prohibited for all personnel due to the entity's unpredictable and invariably lethal behavior toward living subjects.
**Description:** SCP-XXXX presents as a tall adult male of indeterminate ethnic origin. The entity does not appear to age; physical descriptions recorded across three centuries remain functionally identical. SCP-XXXX has not been observed sleeping, eating, or communicating through conventional means in any documented encounter.
SCP-XXXX has been documented operating continuously since at least 1800 or before that, making it one of the longest-active humanoid anomalies in Foundation records.
**Anomalous Abilities:**
SCP-XXXX possesses the following confirmed anomalous abilities:
1. Vocal Mimicry
SCP-XXXX can perfectly replicate any human voice, including speech patterns, emotional tone, and accent. It uses this voice to lure targets and call victims out in the voice of a family member, a neighbor, or emergency personnel. Survivors consistently report being unable to distinguish SCP-XXXX's vocal replication from the genuine voice of the individual being mimicked until physical proximity was established.
2. Teleportation
SCP-XXXX appears able to teleport. The Foundation frequently has chased the Entity across multiple locations globally, doing so, the entity disappeared in matter of a second. We theorize the entity use this mechanism to chase the victim and escape from authorities.
3. Biological Immortality
Recovered footage from multiple incidents documents SCP-XXXX sustaining gunshot and stab wounds inflicted by victims attempting to defend themselves. In all recorded cases, SCP-XXXX continued operating without any observable reduction in capability or response to pain stimuli.
4. Residential Intrusion
SCP-XXXX displays a pronounced behavioral pattern of entering private residences. Victims report gradually becoming aware of its presence. The victim described its voice was slightly out of place, like sounds from another room and a voice consistent with but not identical to a known individual. By the time they understand what is happening, SCP-XXXX is already inside.
Forensic analysis of SCP-XXXX incident sites indicates victims are subjected to prolonged physical trauma before death. Remains are found eviscerated, with a precision that has led multiple forensic analysts, the forensic specialists were subsequently administered amnestics. The Entity method would be described as methodical rather than frenzied. SCP-XXXX does not appear to be acting out of rage by the incident site, instead It appears to be taking its time to do it.
----
**Historical Record:**
Foundation archival research has identified SCP-XXXX activity dating to at least 1888, documented in death records in rural England. They describing a figure seen entering homes at night. The description perfectly matches.
The following historical figures or cases are still theory about SCP-XXXX attribution, though confirmation is impossible:
Whitechapel Murders, London, 1888 — known publicly as the "Jack the Ripper" killings. The surgical precision of the wounds, the inability of police to identify a suspect despite multiple witnesses in the area, and the sudden cessation of killings are consistent with SCP-XXXX's pattern. No body of "Jack the Ripper" was ever found after that case was discussed about as legends.
Zodiac Killer cases, California, 1968–1969 — the taunting communications sent to police are anomalous. Handwriting analysis, the analysis has never produced a consistent psychological profile. Several letters contain phonetic patterns that Foundation linguists have flagged as inconsistent with any known regional dialect.
At least 14 other unresolved serial case files across Europe, Southeast Asia, and South America could have been associated to SCP-XXXX with varying degrees of confidence.
SCP-XXXX does not appear to operate continuously across months. There are gaps, sometimes decades, in between documented activity pattern. The frequency of SCP-XXXX during these periods is unknown. Whether it is dormant, operating undetected, or simply elsewhere is a matter of ongoing debate between the scientists.

> Incident XXXX-A1, 201█:
Subject ██████, age 4█, was found strangled to death
inside a private residence on South ██████. Investigators
found no signs of forced entry, no signs of struggle,
and no established motive. Case suppressed by Foundation
assets within 72 hours.
> Incident XXXX-A2, December 201█:
Two victims — a woman and her ██-year-old daughter —
were found stabbed to death in their apartment in
███████. No forced entry. No clear motive. The precision
of the wounds was flagged by a Foundation-embedded
forensic analyst before standard amnesticization
protocol was applied.
> Incident XXXX-A3, February 20██
An entire factory was burned to the ground, the source of flame led to a dead end. Majority of the worker deceased in the process. The CCTV Footage show the subject was observed trespassing within the factory and ██████ the entire workers.
> Incident XXXX-A4, 202█
Police cruiser raid a potential serial killer home at ██████, responding officers found evidence consistent with recent violent activity despite evidence suggesting the incident had occurred moments prior. The suspect was never found.
> Incident XXXX-A5, June ████
Eight individuals — a family of six and two overnight guests — were found deceased inside a private residence in ████████, Iowa. All victims had sustained fatal blunt force trauma, inflicted while asleep. No signs of forced entry. No confirmed suspect was ever charged despite investigations spanning several decades.
Foundation archival review flagged this case in ████. The wound pattern and the absence of forced entry are consistent with SCP-XXXX's established profile. The deliberate nature of the injuries is inconsistent with a crime of opportunity.
[Archival note: Civilian documentation of this incident proved impossible to fully suppress due to the era of occurrence. The residence now operates as a tourist attraction. A Foundation proposal to acquire and demolish the property was declined at the administrative level, which I personally find difficult to accept. — Researcher ██████]
> Incident XXXX-A6, January ████
Nine experienced mountaineers were found deceased on the eastern slope of ████████ Pass in the Soviet Union. Their tent had been cut open from the inside. The victims were found scattered across a radius of approximately 1.5 kilometers from the campsite — several had fled in temperatures of −30°C without adequate clothing or footwear.
Two victims displayed severe internal trauma, including fractured ribs and a fractured skull, with no corresponding external wounds. One victim was found missing both eyes. The Soviet investigation concluded cause of death was an "unknown compelling force" and sealed the files.
Foundation analysts reviewed declassified materials in 20██. The behavior of the victims — abandoning shelter in freezing conditions, dispersing rather than grouping, separating from one another — is consistent with SCP-XXXX's vocal mimicry being used to draw individuals away from the group sequentially.
[Researcher ██████ note: They heard something outside the tent. Each of them heard something different. I don't know how else to explain it.]

**Interviewer:** Prof. ██████, senior researcher
**Subject:** ██████, survivor civilian
**[BEGIN LOG]**
**Prof. ██████:** My name is Prof. ██████. You are here to
answer our questions, don't ask any questions. Understood?
**Subject:** I understood
**Prof. ██████:** I'm going to show you a photograph. Take
your time.
[Photograph of SCP-XXXX composite sketch is placed on
the table.]
**██████:** This look familiar, where you get–
**Prof. ██████:** I strongly advise you not to ask questions.
**██████:** At my house.
**Prof. ██████:** What did it do?
**██████:** It used my mother's voice the try to enter my house. I was aware that my mother was deceased. So... I go for escape route.
**Prof. ██████:** How did you escape?
**██████:** Through the window. I just... I couldn't think.
**Prof. ██████:** Did it follow you?
**██████:** No. I don't— [Subject becomes visibly distressed. Interview paused for 43 seconds.]
**Prof. ██████:** That will be all. Please take this
medication before you leave.
**██████:** T-thank you. B-but–
