Behemoth is an ancient mythological beast mentioned in the Hebrew Bible's Book of Job and various other literary sources. No definite physical description exists of this creature, but many perceptions of it include a rhinoceros, an elephant, a buffalo, a hippopotamus and even a dinosaur. The Dictionnaire Infernal describes Behemoth as a demon that possesses traits of several creatures, including the bloated body of a hippo and the head of an elephant. Metaphorically, the name Behemoth has come to be used as a generic term for any large or powerful entity.
According to the Dictionnaire Infernal, Behemoth is said to be the high cupbearer of Hell and rules over the domain of gluttony. Weirus considered Behemoth might possibly be Satan himself.
