Trivia

 * Aside from Lucifer, none of the other demons have been confirmed, save for a possibility in a demon named Mammon who is associated with the Greed Ring, which fits the Prince of Greed from the classification.
 * There is an upcoming character in the trailer for the first season of Helluva Boss that bears a striking resemblance to the demon prince of Lust, Asmodeus, both having three heads (one of a bull, and one of a ram) and rooster-like legs.
