Beelzebub

Beelzebub, Lord of the flies, One of the highest demons in Roundworld's Hell who takes the form of a pillar of angry blood-red light, within which a humanoid figure may dimly be perceived, which has a speaking voice as if a million flies have all decided to harmonise their buzzing. He manifests at the climax of Good Omens to express his dissatisfaction with the way the Apocalypse has gone so far under the management of Anthony Crowley.
