@jokerxhisoka Asmodeus (/ˌæzməˈdiːəs/; Greek: Ασμοδαίος, Asmodaios) or Ashmedai (/ˈæʃmɪˌdaɪ/; Hebrew: אַשְמְדּאָי, ʾAšmədʾāy), also Ashema Deva, is a prince of demons, or in Judeo-Islamic lore the king of the earthly spirits (shedim/jinn), mostly known from the deuterocanonical Book of Tobit, in which he is the primary antagonist. In the Binsfeld's classification of demons, Asmodeus represents lust. The demon is also mentioned in some Talmudic legends; for instance, in the story of the construction of the Temple of Solomon.
He was supposed by some Renaissance Christians to be the King of the Nine Hells. Asmodeus also is referred to as one of the seven princes of Hell. In Binsfeld's classification of demons, each one of these princes represents one of the seven deadly sins (lust, gluttony, greed, sloth, wrath, envy, and pride).
It is said in Asmodeus; Or, The Devil on Two Sticks that people who fall to Asmodeus' ways will be sentenced to an eternity in the second level of hell.
TL;DR Asmodeus is the main character of their own story, and thus has access to main character powers such as hidden strength, bullshit powers, and plot armor.
