Belphegor

The Detestable Idol, The Great Phallos, The God of the Moabites, Baron of The Depths

Belphegor is a demonic debt collection agent, not so much collecting them herself, but ensuring those who are too busy to get out of Hell has somewhere to turn for collection on outstanding debts. For a price, of course.
From her offices on 127 Broadway, creditors can have a sit down in Inter-Theological Recovery Services and ensure that their debts will be paid in full and soon.
Usually appearing as a young woman, his demonic shape is rather less appealing, though he reserves that for special occasions.
