Taking a wild ass guess I would say the Seraphim, The "winged serpents" of old... Many are mentioned in the texts. Baall, Molach, Satan, El, Yahweh, Lucifer and a number of lessor deities as well as their hybrid human "Nephilim" descendent Bloodlines. Partial list. Pretty much every culture worshiped a winged serpent that demanded human and other flesh sacrifice.
