SCP-106

SCP-106 is a Keter-classified SCP.

Description
SCP-106 appears of that of a diseased and rotting old man. Whatever SCP-106 touches corrodes, allowing the monster to horribly mutilate anyone with a single touch and phase through solid surfaces with ease. SCP-106 stalks and later slowly chases any human it spots, specifically males aged from 10 to 25, and incapacitates them by brutally severing tendons before dragging them to his pocket dimension. SCP-106 is completely in control of this dimension, and uses it as nightmarish torture grounds with unspeakable mutilation on the victim that lasts from hours to months, before sending the still living hollowed out shells of what the victim originally was back to the real world. While SCP-106 can be mistaken for a mindless predator, it is actually fully sentient and fully aware of the unimaginable pain its causing, having an incredibly sadistic personality.

Events
SCP-106 is the main antagonist of the tale Treats, where he escapes his cell and terrorizes a boy on Halloween as the beast mercilessly tortures his friends to death. SCP-106 is eventually recaptured, found stepping on pumpkins, but after returning to his cell, sees that the researchers found out he'd been collecting the teeth and fingers of the victims he'd slaughtered last night.

SCP-106's origins are revealed in the tale The Young Man. He was once a Corporal named Lawrence in World War I, where his background, family, and even first name was unknown. He wasn't even recorded as signed up, he just randomly appeared in a military bunker one night. Lawrence radiated an indescribable aura of repulsion, making him an outcast, and his only odd behavior was giggling in his sleep. One night, he murdered a private and strung his intestines up by a barb wire system, and was later transferred to a mental hospital where he sexually assaulted a nurse. One morning, it was discovered that the entire ward was drenched in black ooze, every single human in the ward was missing, and a spiral of severed teeth centered the chaos. The teeth was identified to have belonged to all of the ward's inhabitants except one...

Containment Procedures
SCP-106 must be contained in a sealed cell solely composed of 40 layers of lead-lined
