Beelzebub is the Demon King of Gluttony, a demon known for overindulgence.
Beelzebub has a single spiral horn in the middle of her forehead and small black wings sprouting from her shoulders, which she can retract to hide them. She has green eyes and long blue-black hair done in hip-length twintails and chin-length bangs. She wears a silver metal collar around her neck which has a long metal chain leash wrapped around her body all the way to her feet. She also wears a black and green blouse with chest window and green fairy-skirt with a white maid's apron over it, white thigh-high stockings, and matching black-and-green gloves and shoes She is usually shown holding and eating a huge meat drumstick.
Lady Beelzebub is a Demon King that Lady Lucifer keeps like a pet, bdsm-style, as Lucifer is the only being who can give her orders.
If she has interests other than eating, and what abilities she has in the first place, nobody knows it other than Lady Lucifer.
Beelzebub is actually a most merciful Demon King as she once saved Leviathan all by herself when she got knocked out unconscious at the bottom of the ocean, in a fight with Satan, by secretly releasing all of Leviathan’s potential power, through magical chanting and kissing her on the forehead, which caused Leviathan to wake up and boost up her level of fighting prowess.
Currently, only Lucifer knows her abilities. Although it's hinted she has quite an impressive stamina, being able to outlast Lucifer in an eating contest before being taken to hospital.
