Bael is often described as having three heads: that of a man, a cat, and a toad, all perched on the body and legs of a spider. He speaks in a hoarse but eloquent voice and grants both wisdom and invisibility to men. He is said to rule over 66 legions. He is likely a demonization of the Canaanite god Baal.
He appears in Devil Survivor as part of the body of the demon Belberith.
