The devil (Beelzebub), also known as Baalzebub, the Lord of Flies, or Ba'al Zebul, Lord of the High House for a millennia has been a prominent arch-duke of Hell until being promoted to ruler during the short time Hell was ruled by a Triumvirate. When Lucifer abdicated and closed down Hell, Beelzebub changed his bug form into a humanoid body, and made a failed attempt to climb back to Heaven and destroy all mankind. Soon after he concluded that evil had become mundane and attempted to commit suicide, involving himself in a clash with Kid Eternity in the process. At the time, he was seemingly dying. Beelzebub has a vast circle of demons in Hell. Among his ranks were Choronzon, Major Domo, Buzz, and Anton Arcane.

Beelzebub is commonly described as placed high in Hell’s hierarchy; he was of the order of cherubim. According to the stories of the 16th century occultist, Johann Weyer, Beelzebub led a successful revolt against Satan and is the chief lieutenant of Lucifer, the Emperor of Hell, and presides over the Order of the Fly. Similarly, the 17th century exorcist, Sebastien Michaelis, in his Admirable History (1612), placed Beelzebub among the three most prominent fallen angels, the other two being Lucifer and Leviathan, whereas two 18th century works identified an unholy trinity consisting of Beelzebub, Lucifer, and Astaroth. John Milton featured Beelzebub as seemingly the second-ranking of the many fallen cherubim in the epic poem Paradise Lost, first published in 1667. Wrote Milton of Beelzebub “than whom, Satan except, none higher sat.”
