The supplied sources contain no origin story, genealogy, or mythic narrative for an entity named 'Az'. The only relevant material in the corpus treats 'demon' as a broad category (see Source 1) and describes Avestan daevas as Zoroastrian supernatural beings to be rejected (Source 11). Beyond noting that many traditions feature harmful unseen beings, there is no source-provided origin for 'Az' specifically.
No source in the provided material gives a physical or visual description of an entity named 'Az'. General treatments of 'demons' in the corpus do not supply consistent appearance details that can be attributed to a specific being called 'Az'.
There are no source-attested, specific powers or behaviors for an entity named 'Az'. By analogy to the general category discussed in Source 1, demons are often conceived as malevolent supernatural entities capable of harming humans and, in many traditions, causing possession that may require exorcism; however, these are category-level observations and not documented abilities of a named being 'Az'.

Daeva
In Zoroastrian and Iranian tradition, a daeva (Avestan daēuua) is a class of supernatural being that the Zoroastrian revelation repudiates; in the oldest texts they are 'gods that are (to be) rejected' and in later tradition they come to be depicted as divinities promoting chaos and, ultimately, as personifications of evil.

Djinn
The class of supernatural beings created from smokeless fire in Islamic cosmology — a parallel civilization to humanity, capable of belief or unbelief, with their own prophets, society, and judgment before God.
