SCP (XX), "The Other"

Euclid-class SCP

Basic concept:

The subject is a human female with an anomalous condition similar to the "lycanthrope" myth. This "werewolf state" displays a personality of its own, and has expressed loyalty and endearment to the human that it inhabits.

SCP (X)-1 is the subject's human form, a Caucasian North American female, age 2█ named ██████ ██████. The subject displays willingness to cooperate with the Foundation, though has voiced concerns about how little information she is given about her condition. Any amnestics taken before the emergence of SCP (X)-2 loose effect and the SCP (X)-1 regains all memories. SCP (X)-1 will often berate and scold personnel for attempting to alter her memories or hide things from her. Because of this ability to recall memories that should have been erased, personnel are to be cautious to not disclose any classified information nearby SCP (X)-1, as there are no permanent means of removing it from her memory. It should also be noted that anyone who administered amnestics to SCO (X)-1 are to be relocated from the SCP (XX) containment unit, as SCP (X)-2 may attempt to attain retribution against them in a future escape attempt.

SCP (X)-2 is the subject's "werewolf" form — it appears as a large female canis lupus bearing dark-gray fur, standing at 3 meters tall at the shoulder, and 6 meters long from nose to tail. It refuses to be weighed, but research staff has determined that it weighs approximately 800 kilograms. SCP (X)-2 has displayed telepathic abilities, able to access surface-level thoughts and communicate with creatures within a 30 meter radius. SCP (X)-2 has shown to be able to access SCP (X)-1's memories, able to recite details from the subject's childhood, previous places of work, and social security number, among other things. SCP (X)-2 is aggressive towards most Foundation faculty that approach it, though some staff has been able to converse with the subject with little to no hostility directed towards them. It seems to express that it only wishes for the welfare and happiness of SCP (X)-1, and views the Foundation as a threat to it. It shows signs of irritation if asked if its existence has ever brought SCP (X)-1 any happiness, and refuses to answer any more questions about itself or SCP (X)-1.
Staff are to be supervised by Dr. ██████ when interacting with SCP (XX), due to their familiarity with the subject and their anomalous properties.

SCP (X)-2 has attempted to escape from the facility on numerous occasions. The subject's body appears to be immune to most forms of weaponry, with blades, blunt-force instruments, bullets and projectiles merely striking its body with no effect. Explosives have been shown to be effective at stunning SCP (X)-2, but do not show any permanent damage, any wound created from the blast quickly heals. Weapons lined with silver have been proven to harm SCO (X)-2, but any wound attained through these means will persist upon reverting back to SCP (X-1). Electricity, proven to disrupt SCP (X)-2's physical form, causing it to flicker and shimmer, is the most effective tool to stun SCP (X)-2 without harming SCP (X)-1. It has been theorized by Dr. ██████ that its "body" is actually a telekinetic projection from SCP (X)-2, due to its properties.

SCP (X)-2 has shown strange behavior during their escape attempts. Whenever they attack any security personnel, they rarely ever bite at them, preferring to bash them into walls or slam them into the ground. If it does use its teeth, it takes care to make sure that the person is dead by tearing the body apart. It does this every time it has attacked with its teeth, even when under fire. Much like the lycanthrope myth, it is possible that bites are able to reproduce SCP (XX) into others.

+ SCP (XX) Regular Shapechange Schedule

Waning Gibbous and Waning Crescent
The subject awakens with no memory of the time spent as SCP (X)-2. They show signs of tiredness and lethargy for the first morning, but often recovers by the end of day. Any amnestics taken by the subject are neutralized upon awakening and any memories affected by any amnestic effects are restored.

Waxing Crescent
The subject begins to show signs of discomfort, and has expressed that she begins to feel "the other," as she describes in her briefing upon arrival to the containment facility. As the full moon approaches, the subject begins to hear more and more thoughts from SCP (X)-2. These thoughts become more intrusive as time passes, and the subject will often mutter in response to the voice in her head.

Waxing Gibbous
SCP (X)-2 begins to manifest, its psychic projections capable of being heard by others. Though SCP (X)-1 shows no signs of physical change, there are moments where SCP (X)-2 displays the ability to take control of the subject's body, as well as being able to do so without SCP (X)-1's notice.

Full Moon
When the sun sets and the moon is full, SCP (X)-2 takes control of the subject completely and begins to change shape. The process is instantaneous, with SCP (X)-2 appearing from out of thin air. All cameras observing this change show only static in the frames in which it occurs.
