Item #: SCP-5366
Object Class: Safe
Special Containment Procedures: SCP-5366 is to be put in a regular apartment-type living room with an additional room, functioning as a bathroom. SCP-5366 is to be kept there only for the time of experimentation and research with SCP-5366, as it doesn't show any signs of harm.
Description: SCP-5366 is what appears to be an un-anomalous male-gendered human being. It can function normally, has memories of it's past and has human-like emotions and/or reactions. Every once in a while, typically about a week, SCP-5366 will completely transform it's physical form into another male. It's appereance can vary immensly after transforming, including the clothes SCP-5366 is wearing, tone of voice, height and skin colour. SCP-5366 will, in all instances, remain the same gender. When asked about it's memories, SCP-5366 will answer the same as before the transformation, and will keep saying it's skin colour, height, hair colour and all other physical attributes were there all along, and will deny/confuse about any kind of changing. Anyone who witnesses the transformation of SCP-5366 will experience short-term amnesia, not being able to recall anything after approximately 15 seconds prior to the transformation initiation. Personnel standing too close to the SCP when transformation commmenced, experienced severe nausea for approximately 60 minutes in all instances. Researchers have tried filming the transformation on camera, but they experienced amnesia every time the reviewed it as well.
Experiment #1: When in a (in-height) short form, SCP-5366 was locked inside a small chamber with a very low ceiling. The experiment would tell if the conversions are controllable to some extent. After a while, SCP-5366 was released from the chamber, looking differently physically, but still maintaining the small height. This confirms SCP-5366 is generally able to take shape of its surroundings.
Experiment #2: An airborne form of the common cold virus was released inside SCP-5366's chamber. SCP-5366 caught the virus very soon and showed normal symptoms of the common cold. After the transformation, the symptoms and presence of the virus were completely gone. Confirmingly, SCP-5366 heals completely after every conversion.
NOTE: SCP-5366 does NOT experience amnesia after the transformation. It maintains all memories, so the amnesia effect does not work on it. SCP-5366 also does not transform into any known human being on Earth, it's physical attributes in a sum not maching anyone in all instances.
