SCP-106 is a mobile threat, and appears quite often. It is unknown if this is the point of origin for SCP-106, or a simple “lair” created by SCP-106. Entering a wall, and exiting from the ceiling). SCP-106 is then able to exit this dimension from any point connected to the initial entry point (examples: “entering” the inner wall of a room, and “exiting” the outer wall. SCP-106 is able to “vanish” inside solid matter, entering what is assumed to be a form of “pocket dimension”. SCP-106 is capable of passing through solid matter, leaving behind a large patch of its corrosive mucus. This is observed as rusting, rotting, and cracking of materials, and the creation of a black, mucus-like substance similar to the material that coats SCP-106. SCP-106 causes a “corrosion” effect in all solid matter it touches, engaging a physical breakdown in materials several seconds after contact.

This appearance may vary, but the “rotting” quality is observed in all forms. SCP-106 appears to be an elderly humanoid, with a general appearance of advanced decomposition.
