Name: Asmodeus
Type/Title: Lust demon, prince of Hell
Origin: Judeo-Christian; Dungeons and Dragons

Not only is Asmodeus a figure which appears in Christian mythology, he is also a name featured in Dungeons and Dragons lore. To the Christians, Asmodeus is the lustful prince of Hell who inspires infidelity and adultery. He was among those angels who fell with Lucifer. For D&D players such as myself, he is the Devil himself. According to the 3.5e Fiendish Codex II Tyrants of the Nine Hells, Asmodeus is the King of Hell, and quite the force to reckon with.
