At first glance, SCP-106 resembles an elderly humanoid with advanced signs of Severe decomposition. It remains immobile for extended periods, awaiting prey, primarily targeting humans aged 10-25. When attacking, it damages organs and muscles, then drags the incapacitated victims into its pocket dimension. SCP-106's touch induces corrosion in solid matter, causing rusting, rotting, and cracking, with a harmful effect on living tissues for six hours. It can traverse solid objects and enter a presumed pocket dimension, exiting from various points. The dimension's origin remains unknown to this day.
