Angra Mainyu

Angra Mainyu is the spirit of destruction and evil in Zoroastrianism and is comparable to the Devil in some Jeudo-Christian religions, however unlike most portrayals of Satan Angra Mainyu is seen as a deity rather than a demon (though the two can overlap).

Angra Mainyu is seen as a chaos deity as well as a destroyer deity - although he is also seen as "evil" he is not officially recognised as a god of evil, though he does come close.

Angra Mainyu rules over the Daeva, which are similiar to demons in other religions, and opposes the deity known as Ahura Mazda (which is another name for God).
