SCP-106

Summary
SCP-106 appears to be an elderly humanoid, with a general appearance of advanced decomposition. This appearance may vary, but the “rotting” quality is observed in all forms. SCP-106 is not exceptionally agile, and will remain motionless for days at a time, waiting for prey. SCP-106 is also capable of scaling any vertical surface and can remain suspended upside down indefinitely. When attacking, SCP-106 will attempt to incapacitate prey by damaging major organs, muscle groups, or tendons, then pull disabled prey into its pocket dimension. SCP-106 appears to prefer human prey items in the 10-25 years of age bracket.

SCP-106 causes a “corrosion” effect in all solid matter it touches, engaging a physical breakdown in materials several seconds after contact. This is observed as rusting, rotting, and cracking of materials, and the creation of a black, mucus-like substance similar to the material coating SCP-106. This effect is particularly detrimental to living tissues, and is assumed to be a “pre-digestion” action. Corrosion continues for six hours after contact, after which the effect appears to “burn out”.

SCP-106 is capable of passing through solid matter, leaving behind a large patch of its corrosive mucus. SCP-106 is able to “vanish” inside solid matter, entering what is assumed to be a form of “pocket dimension”. 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. Entering a wall, and exiting from the ceiling). It is unknown if this is the point of origin for SCP-106, or a simple “lair” created by SCP-106.

Limited observation of this “pocket dimension” has shown it to be comprised mostly of halls and rooms. This activity can continue for days, with some subjected individuals being released for the express purpose of hunting and recapture.
