A scp is a monster thats in a facility and some are dangerous and some are friendly

The SCP Foundation is a collaborative writing website that describes the exploits of the SCP Foundation, a fictional organization responsible for containing entities, locations, and objects that violate natural law (referred to as SCPs or Skips). The majority of the written works on the SCP Foundation website consist of "Special Containment Procedures", each of which purports to be the containment process for a specific SCP. The website also contains several hundred "Foundation Tales", which are short stories set within the universe of the SCP Foundation. There are also various Groups of Interest, or in other terms, other groups that compete with the Foundation in containing anomalies.
