Other groups within the SCP Foundation universe have their own documents about events, people, phenomena, and anomalies written in their own formats. See them all here.
- Powered by a Forsaken Child: It is powered by the suffering of dead human souls trapped in their bodies in agony.

- Canon Immigrant: Originally created as part of the Origins Foundation RP, codified into a GOI format a couple of years after their introduction.
- Magic Music: They have the ability to open portals with their voices.
- No Biochemical Barriers: Lampshaded. A man is surprised to find out that epi pens work on them when one has an allergic reaction.
