Belphegor

Belphegor, Prince of Sloth, Prince of Hell.
First appeared in Season 2.
Close friends with Leviathan.
Member of Ford's Squad
Became friends with Fionn Corvin when they met in Hell. When The Rebellion In Hell came, Belphegor was nominated to take the throne as a ruler of Hell.
He is aided by Proserpine And The Sisters Of The Whip, who are his eyes and ears and also advisors.
Belphegor will sometimes declare in his mild manner: "I was there for the original 'Better to stand in Hell than kneel in Heaven' speech. The original version, not the watered-down repeated version."
By this he refers to Lucifer's original intention of making Hell a paradise of democracy, instead of how it was interpreted and re-interpreted and repeated over the years to become "Better to reign in Hell than serve in Heaven" speech, the speech of a king rather than a revolutionary.
