In Babylonian mythology, the Anzu was a storm bird. The demon was a cross between a lion and an eagle. Anzu guarded the tablets of destiny for the god Ellil while he bathed. The tablets made the word, of whoever possesed them, reality, so when Anzu became greedy and stole them, he was unstoppable. That is until Ninurta (son of Ellil) was sent to recover the tablets. At first Anzu used the tablets to ensure that none of Ninurta's arrows could reach him, but after the god Ea instructed him in defeating Anzu, Ninurta was victorious and slew the deviant.
