The character of Beelzebub?

Beelzebub is the chief of the devils. He is Satan's "second-in-command." As the first devil to awaken on the fiery lake, He is also the audience for Satan's opening speech. Like Satan/Lucifer, Beelzebub is associated with light—or rather, lost light. It is thus appropriate that Beelzebub, the first to join in Satan's plans for rebellion in Heaven, is the first to respond to his exhortations in Hell. Beelzebub's name, in Hebrew, means "lord of the flies," and he is an appropriate commander of the demons who, like flies, swarm into Pandemonium for the council.

At the council of devils (Book II), Beelzebub, like Satan, is content to wait until the others have had their say. (See also Moloch, Belial, and Mammon.) As the final (and strongest) speaker, when he does speak, his grave manner, majestic face, and stately words present an effective contrast to Moloch's reckless despair, Belial's hollow and slothful vice, and Mammon's greed. A true statesman and loyal second-in-command, he presents not his own strategy, but Satan's, promoting the subtle plan of taking revenge against God by seducing or destroying humankind.
