Item #:
SCP-XXXX
Object Classification:
Keter
Special Containment Procedures:
It is to be contained in a 5 by 5-meter room, no taller than 10 meters. No lights can be present in the room. An airtight sealed door must be used or else there is a risk of escape by SCP-XXXX. Cameras must be on at all times, with at least 2 people watching it.
Description:
SCP-XXXX is a black blob of slime-like substance. It will latch on to any which touch it and enter through the mouth and eyes. Once in the host, it will be fully in control of their body. The host body decays within a few hours. While in the host, it multiplies its mass.
Of the 50 that have been exposed to SCP-XXXX, none have survived. Lights add to its mass, making it more of a threat. We have found that when at a large mass, it creates small, humanoid creatures, called SCP-XXXX-2. These creatures are not hostile unless SCP-XXXX-1 interferes.
We have found that if we put a person in a sealed glass tube, SCP-XXXX-1 cannot do anything to them. When there is only one person watching SCP-XXXX-1, it turns into that person's greatest fear.
