God. Not I think any adaption is better than the one from the Bible but when a character obtain "Godhood", the Abrahamic God is basically the one most writers use as a reference/comparison. The philosophical debates from these stories are interesting.
This is a good, albeit oddly specific question. And I do think there are a lot of characters from Christian mythology that have been really well implemented in other fiction. Just look at the characters in Good Omens, many of them are angels and demons lifted from Christian mythology, and it makes for a bloody good laugh.
I hope you don't take offense to the idea that many people here may be of other religious beliefs?
From all points of view Abrahmic religions are as much a mythology as Hellenistic, Norse, Egyptian, or Roman myth... Hell Star Wars and the very comic books this website is made for could be considered mythologies.
Just to drive my point across lets google the definition of mythology
"a collection of myths, especially one belonging to a particular religious or cultural tradition.
"a book discussing Jewish and Christian mythologies""
