Pazuzu

Pazuzu, King of the Wind Demons, is the demon lord of the sky, temptation, and winged creatures. He counts himself among the most ancient of demon lords, though his constant warring with Lamashtu has hindered his accumulation of power to the point of denying him godhood. He is exceptionally active in meddling in mortal affairs and takes great pleasure in possessing and corrupting good-hearted folk who invoke his name. Pazuzu appears as a humanoid figure with eagle's talons, two pairs of bird wings, a scorpion tail, and an avian demonic head. He is worshipped by harpies, other evil winged creatures, and by countless champions and clerics who fell from grace at his temptations.
