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.

SCP-106 appears to go through long periods of “dormancy”, in which it will remain completely motionless for up to three months. The cause for this is unknown; however, it has been shown that this appears to be used as a “lulling” tactic. SCP-106 will emerge from this state in a very agitated state, and will attack and abduct staff and cause gross damage to its containment cell and the site at large.

SCP-106 appears to hunt and attack based on desire, not hunger. SCP-106 will attack and collect multiple prey items during a hunting behavior event, keeping many “alive” in the pocket dimension for extended periods of time. SCP-106 has no determinable “limit”, and appears to collect a random number of prey items during an event.

The inner dimension accessed by SCP-106 appears to be only accessible by SCP-106. Recording and transmission devices have been shown to still operate inside this dimension, though recordings and transmissions are very degraded. It appears that SCP-106 will “play” with captured prey, and appears to have full control of time, space, and perception inside this dimension.

when faced with highly complex/random assemblies of structures, SCP-106 can be “confused”, showing a marked delay on entry and exit from said structure. SCP-106 has also shown an aversion to direct, sudden light. This is not manifested in any form of physical damage, but a rapid exit in to the “pocket dimension” generated on solid surfaces.
