SCP-106, The Old Man
by Zcoper
SCP-106, The Old Man adds a Forge monster from the SCP universe that breaches containment, drags players into a Pocket Dimension, and leaves corrosive sludge behind.
What it does
In the SCP fiction, SCP-106 is known as Old Man Larry, a rotting humanoid with a wicked smile. The mod brings this creature into the world as a new hostile mob. It walks through solid blocks, and wherever it walks it leaves a trail of corrosive sludge. When it breaches containment, it can appear beneath a player at any moment. On contact it pulls the player into the Pocket Dimension, where victims are left to rot, and holes in the ground vanish soon after.
SCP-106 only spawns after it has been breached, and a breach can be forced with a creative item. The Containment Chamber sits somewhere in the generated world; pulling a lever there, operating a Femur Breaker and waiting briefly returns the creature to confinement, while Tesla Blocks can stun it for a period. The mod is created with MCreator and requires Geckolib on Forge. It is a client and server mod, so the server and every player need it, and it is released under All rights reserved, so it is not open source. Files are published for 1.19.2, 1.19.4 and 1.20.1, and the 1.20.1 build is the latest at 1.0.0.
Key features
Pocket Dimension escape
Players taken into the Pocket Dimension must find a way out, and victims left there rot away over time.
Breach-only spawning
SCP-106 appears only after a breach, and the gamerule doOldManSpawn controls whether it can spawn.
Containment Chamber
A chamber in the world can recontain the creature through a lever, a Femur Breaker and a short wait, with a sound cue when it is captured.
Corrosive trail
Each step leaves corrosive sludge behind, so the ground around the creature becomes a hazard to cross.
Tesla Blocks
Tesla Blocks can temporarily neutralize SCP-106 during a recontainment attempt.
