Beelzebub

Beelzebub is one out of seven kings of Hell.

It is unknown what type of entity he is, whether he's a fallen angel or something else. He is described as having an iridescent dark green body, like a bottle fly. His wings are seethrough and iridescent as well. He is surrounded by flies, and is very loud. Despite having a temper, he appears very orderly and polite.
