Agrath is in Jewish demonology, a powerful female demon. Agrath (beating) and her mother, Maklath, are in constant struggle against Lilith. Agrath commands 18 myriads (Legions) of evil spirits and rides in a big chariot.

She is most powerful on the nights of Wednesday and Saturday, when she and her mother devour victims, especially people who are out alone.
