Hanbi

In Sumerian and Akkadian mythology Hanbi or Hanpa was the lord of evil, lord of all evil forces and the father of Pazuzu.
Aside from his relationship with Pazuzu, very little is known of this figure.
Some have connected Hanbi to Helel, the Jewish name generally equated to Lucifer in Christian thought. However, Hanbi's characteristic of being a shadow born in the underworld, different from the Sumerian gods of the underworld, would make him more similar to the concept of the Jewish shedim and se'iri or the Islamic shaitan.
