Item #: SCP-xxxx
Object Class: Euclid
Special Containment Procedures: SCP-xxxx Is to be contained in a 204 meters square, climate controlled environment constructed from the unknown material produced by SCP-194 with an input of steel on the Very Fine setting (No thinner than 15 centimetres on any given surface), and decorated with vegetation native to the taiga environments in SCP-xxx's home of Siberia. There must be no less than 1 meter of soil on the floor at it's lowest point, rivers with fresh water in circulation, and the walls are to be decorated to mimic Siberia to reduce the stress response of SCP-xxxx should it approach one of the walls. Stone formations are to be included as well, with several of these formations including caves suitable for many sizes of creatures, both for prey to hide in, and for accommodating SCP-xxxx's many shapes.
SCP-xxxx is to be provided with fresh prey daily to hunt in it's environment, such as wolves, elk, bears, and moose. Cooperative behavior will be rewarded with more challenging hunting material such as hippos and alligators. Cooperative behavior may also be rewarded with traditional media entertainment, such as movies and books with Russian language localization, should SCP-xxxx request it. Spoilers to any form of media are to be avoided at all costs, at risk of personal injury and containment breach. Japanese cartoons are strictly prohibited, as SCP-xxxx is prone to mimic behaviors seen on television.
There must be a single door leading to a security checkpoint, where security are to identify each incoming and outgoing personnel for signs of SCP-xxxx, and should they prove to be SCP-xxxx in an altered form, security personnel are authorized to use flamethrowers to drive SCP-xxxx back into containment, and rewards for compliance with Foundation directives will be immediately suspended, pending authorization from level 3 personnel.
Description: SCP-xxxx has a variety of forms, but it's most common one when interacting with staff is a vaguely humanoid shape with a blue snake head, the body of a fit, Caucasian man with four arms and claws extending 7 centimetres from each hand, and the legs of a steppe wolf. This form is 213 centimetres tall, and has varying weights directly related to how much prey it has consumed, though the physical dimensions of the form remain the same. The head and spine always remain unchanged, and is considered to be SCP-xxxx's natural form. In it's natural form, it looks indistinguishable from a blue snake with black diamonds patterned on it's back.
SCP-xxxx is capable of assimilating organic material from various species of the animal kingdom, and shaping it however it desires. SCP-xxxx has full control over every cell in it's body, and can separate any part of it's body from any other part, with incisions as small and precise as needle holes, up to dismembering full limbs. SCP-xxxx theoretically has a reaction time of 0.10 milliseconds, which would allow it to avoid nearly any attack. Though SCP-xxxx has exceptional reflexes, it has been proven that the type of weapons it struggles to adapt to the most are incendiary weapons, as it has not shown the ability to rapidly regenerate.
SCP-xxxx is also able to camouflage itself and mimic the textures of anything in it's surrounding environment. This, along with it's ability to shape it's form at will, makes SCP-xxxx a very dangerous ambush predator. Refer to Addendum xxxx-1 for staff related incidents.
Discovery: SCP-xxxx was discovered in the Stolby Nature Sanctuary, after intercepting reports of several local hikers disappearing, followed by reports of possible sightings of missing persons gorging themselves on wildlife before disappearing into the trees.
