Anzû

Anzû, also known as dZû and Imdugud, is a demon in several Mesopotamian religions. He was conceived by the cosmic freshwater ocean Abzu and mother Earth Mami, or as son of Siris. In Babylonian myths Anzû was depicted as a massive bird - also as an eagle with lion head - who can breathe fire and water. This narrative seems to refer to much earlier Sumerian myths, in which he appears as a half-human storm bird who stole the tablet of destiny, challenging Enlil's power over his organisation of different gods that provided Mesopotamia with agriculture.
