Daeva
{{Quotation |title=Daeva |text=In the Zoroastrian religion, a daeva is a demonic and destructive being. Daevas are combated by the ahuras who help to uphold the moral law. |author= [[Pad of Definitions (1.16 Shadow) |source= Official Website }}
In 1.16 Shadow (episode), Meg summons the deaveas using a black altar. Caleb tells Dean that the Zoroastrian symbol (The "Z") is a sigil for a Daeva and is "very, very old school, like two thousand years before Christ." Dean says that Daeva "translates to “demon of darkness”. Zoroastrian demons, and they’re savage, animalistic, you know, nasty attitudes—kind of like, uh, demonic pit bulls."
Meg has some control over the daveas, but when her black altar is destroyed, the daevas turn on her and she falls from the building.
They are invisible expect for their shadows. When they attack the Winchesters, Sam repels them using a flare gun.
