Item #: SCP-XXXX
Object class: Euclid
Special Containment Procedures: SCP-XXXX and SCP-XXXX-2 are to occupy a standard two-entity humanoid containment cell. All attempts to separate SCP-XXXX and SCP-XXXX-2 must be preceded by informing SCP-XXXX when SCP-XXXX-2 and SCP-XXXX will be reunited and obtaining SCP-XXXX’s assent. This reunion should occur five minutes before the agreed-upon time if possible to minimize the risk of a containment breach.
SCP-XXXX-2 may only wear tear-proof clothing and sleep in tear-proof bed sheets.
A close acquaintance of SCP-XXXX-2 is to always reside in a separate cell on premises. So as to not unnecessarily distress this acquaintance, the Ethics Committee strongly advises that they are kept unaware of SCP-XXXX-2’s containment and living situation.
Description: SCP-XXXX is a humanoid entity that currently resembles a forty-year-old, caucasian human male with brown hair and brown eyes. It currently stands at 1.8 meters tall and weighs 81 kg. Two appendages resembling human arms sprout from its back. From the beginning of the upper “arms” to its wrists, the appendage is one and a half times longer than its naturally occurring arms. Instead of hands, a one-meter long chitinous growth resembling a cat o’ nine tails whip protrudes from its wrist.
SCP-XXXX keeps a roughly six-inch fixed-blade hunting knife of unknown origin in a sheath on its person. Security footage reveals that this sheath is engraved with the phrase “For when you’re ready.” Attempts by Foundation personnel to obtain and analyse this knife has thus far been unsuccessful.
SCP-XXXX engages in an obsessive, paternal relationship with a human, henceforth known as SCP-XXXX-2. SCP-XXXX-2 is currently a sixteen-year-old, 1.7 meter tall, caucasian male with blond hair and blue eyes, weighing 60 kg. SCP-XXXX is highly possessive of SCP-XXXX-2 and will break containment with 100% success rate if it believes SCP-XXXX-2 has “run away.” No known materials can impede SCP-XXXX during these occurrences, during which it will instinctually navigate towards SCP-XXXX-2’s location. Upon “reclaiming” SCP-XXXX-2, SCP-XXXX will cooperate with Foundation personnel if it feels its custody of SCP-XXXX-2 is no longer threatened.
When exposed to knife attacks, anti-tank weaponry, and consistent machine gun fire from Foundation personnel, as well as SCP-████, SCP-XXXX consistently remains unscathed and reports no pain. SCP-XXXX also appears to be immune to any self-inflicted injuries. The only known entity capable of harming SCP-XXXX is SCP-XXXX-2.
Every day, at 0700, SCP-XXXX wakes up SCP-XXXX-2 and informs them that it is instating a new rule. These include “no arguing,” “no slouching,” and “no crying without permission.” If SCP-XXXX believes SCP-XXXX-2 has either purposefully or accidentally broken a prior rule, it will strip SCP-XXXX-2 and administer between 10 and 500 lashes to them using the whips attached to its appendages. SCP-XXXX demonstrates an awareness of rules broken outside of his presence, which it attributes to its ability to “smell guilt”. Despite the apparent cruelty of these actions, SCP-XXXX has expressed in interviews that it believes its lashes are an unfortunate necessity for SCP-XXXX-2’s own betterment.
Roughly 20 days into SCP-XXXX’s custody, psychological evaluations of SCP-XXXX-2 indicate that they harbor homicidal fantasies of SCP-XXXX. When pressed on this, SCP-XXXX-2 usually expresses that they still care about SCP-XXXX from prior experiences, as well as indicating fear of punishment.
Roughly 45 days into SCP-XXXX’s custody of SCP-XXXX-2, SCP-XXXX-2 invariably murders SCP-XXXX; this typically involves SCP-XXXX-2 stabbing SCP-XXXX repeatedly in its sleep with its own knife. Research indicates that the drive to murder SCP-XXXX is either purely or predominantly anomalous.
After SCP-XXXX-2 murders SCP-XXXX, they are to be kept in containment, and their close acquaintance housed on compound is to be moved into containment with them. SCP-XXXX-2 demonstrates a noticeable attachment to SCP-XXXX’s knife, and begins to wear it in the same manner. Three to five days after their homicide, they begin complaining of back pain to Foundation personnel. Roughly two days later, SCP-XXXX-2 demonstrates an increasingly obsessive attachment to the most nearby person they know well; due to the Special Containment Procedure, this is typically the acquaintance they cohabitate with.
Approximately seven to ten days after the murder, a pair of appendages akin to SCP-XXXX’s sprout out of SCP-XXXX-2’s back. SCP-XXXX-2 henceforth is to be considered a new instance of SCP-XXXX, and the acquaintance a new instance of SCP-XXXX-2.
Post-transformation, the new instance of SCP-XXXX retains its previous personality, but with SCP-XXXX’s domineering mannerisms. When asked about the previous SCP-XXXX, SCP-XXXX appears unfazed and responds with phrases like “he wasn’t always nice, but he made me who I am today.” However, this also triggers physiological responses akin to those experienced by trauma victims.
