SCP-106 - Official SCP: Unity Wiki

SCP-106, or "The Old Man" is a keter class SCP and a prominent antagonist of SCP: Unity. It was added in version 0.5.0. 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.

So the scp, cb Unity version of 106 is terrifying
