Baalzebul

Baalzebul (BAYL-ze-bul ) was the lord of Maladomini, the seventh layer of the Nine Hells, and one of the most powerful archdevils. Formerly a celestial archon known as Triel, he bore the titles Fallen One, Lord of the Flies, Lord of the Lies, and the Slug Archduke. The last refers to the form he was cursed with after the Reckoning of Hell; Asmodeus has made his natural form that of a filth-covered giant slug with tiny arms.

Relations
Baalzebul was allied with Belial, but opposed Mephistopheles in all things, and desired revenge on Asmodeus for his humiliation during the Reckoning.

History
Originally an archon named Triel, Baalzebul was cast down into the Nine Hells and promoted to devilhood by Asmodeus himself. Baalzebul was a perfectionist, and this served him well as he climbed the ranks of devilhood. Eventually he ascended to the status of Lord of the Seventh, not just deposing the former Lord but expunging all knowledge of that entity from existence.

Baalzebul was, for a long time, one of Asmodeus's favored. He controlled not only his own layer of Hell but the Sixth as well, through his viceroy Moloch.

During the Reckoning, Baalzebul's forces challenged Asmodeus himself, but were thwarted when Mephistopheles's troops turned on his own. To punish Baalzebul for his insubordination, Asmodeus changed his formerly angelic form into a melted, sluglike one. Suffering from depression, Baalzebul's perfectionism has lapsed, and his layer of hell shows the signs.

Trivia

 * It is likely that his title "Lord of the Flies" is a reference to the 1954 book Lord of the Flies, by Nobel-prize winning British author William Golding.
