Furthermore, I think you're missusing the term Avatar here. It's been a while since I've gone over your excellent series of posts on Wondy, but I don't recall her being explicitly stated as a true avatar before.
And if she has, who's avatar was she? Athena's? And then there's the whole Cosmological Kitchen Soup that gets tossed in with having Greek Dieties use the abilities of Hindu dieties...
Divinely Created Messangers are not Avatars. That's an angel. Western tradition has corrupted the term to suit its own preconcieved notions. Most of my research leads them to be something between the videogame use of the word Avatar and...well, Jesus.
