“Gateways Entity...? I don't think I understand.”
Gateways Entity has not been given an official name; as such, this name is purely conjectural. However, it will be used until an official name is released.
The Gateways Entity is an unknown entity mentioned in Springtrap Location, Unexplained Footage Log and partially seen or heard during the Gateways footage (hence its name). The log explains that this entity seems to be neutral in nature, but becomes hostile upon finding any other sentient bodies. No other information is known about the Gateways Entity, as it is not mentioned again later in the series.
