This SCP has no form and unlimited power, giving it the ability to fly and move through walls. Noclip Ingame.
Able to create anything from thin air with some limitations. Able to use the spawnmenu to spawn in guns, keycards, items, hostile npcs, and possibly nextbots. Spawn limit should be set to 20-30 objects at any given time. A counter should be given to track how many items they've spawned or what other players have taken from his spawn pool.
Before the SCP can use any of its vast power it must place down its soul upon the world. Will first need to put down an entity that is shaped like a metal box/sphere that acts as its body. It is able to put this down anywhere in the map, but only on valid structures. (Like at least a floor) The entity should also be quite large to spot it if its placed somewhere obscure. The SCP's health should be set to 1000, since it will be unable to move it and gives the SCP time to react if it begins losing health.
Notes: Based on its crazy abilities it might be a good idea to make this a special round only, where it spawns in with just d-class or tro. Will probably need to make a simple SWEP to put down the entity, but I think you could use the toolgun for a lot of the other stuff.
