Item #: SCP-4353
Object Class: Euclid
Special Containment Procedures: SCP-4353 is to be kept in a Standard Humanoid Containment cell in Containment Sector-02 at Site-17. The space between the outer and inner cell wall is to be lined with malachite and iron to diminish SCP-4353's anomalous abilities. Bi-weekly psychiatric visits are required in order to avoid further containment breaches (See Incident 4353-1B).
SCP-4353 is generally compliant with site personnel. On the off chance it becomes aggressive, the entity is to be injected with heavy sedatives and returned to its containment cell. If SCP-4353-1 chooses to make an appearance, SCP-4353 is to be sedated and restrained via malachite-lined handcuffs, as well as a locking collar.
Description: SCP-4353 appears to be a female humanoid entity, standing at approximately 180.34 cm and weighing approximately 68 kg. Upon discovery, SCP-4353 was wearing what appeared to be torn hospital wear, which have since been replaced. A small birthmark on the entity's upper arm - which could be easily mistaken for a tattoo - reads "G.W." When asked about the birthmark, SCP-4353 grows uncomfortable and refuses to speak altogether.
SCP-4353 has the ability to create what appears to be a pink, crystalline substance from its mere thoughts. Further research as concluded that said substance isn't made of any known element. However, SCP-4353 appears to have little to no control over this ability, and tends to create the substance when afraid or uncomfortable.
Genetic testing of SCP-4353 reveals that the entity appears to be artificially created - its genetic coding appears perfect, and includes the same signature seen on the entity's arm. However, part of its code appears corrupt and splits off altogether, creating a complete split in the entity's personality. This genetic flaw is designated as SCP-4353-1.
When asked about this genetic flaw, SCP-4353 refers to it as "Project A". The entity claims to have a struggle for control with SCP-4353-1, and can speak freely to it in dreams. When asked for a physical description, SCP-4353 describes it as an "evil and shadowy" version of itself, with "pink eyes and sharp teeth".
SCP-4353-1 has the ability to completely take control over SCP-4353's body, and has a much better grasp over the entity's anomalous abilities. SCP-4353-1 is aggressive, will immediately attack others on sight, claiming that its "protecting her". "Her" is likely referring to SCP-4353.
