Archangel Gabriel

One of the best known angels (and one of three to be specifically named), Gabriel is the messenger of God. According to the Bible, it was he who foretold the births of Jesus and John the Baptist. Because he is explicitly mentioned as being the angel who comes to earth to inform the people, he will often be the main angel interacting with humans, in addition to the higher angels' role as warriors. Many also identify him as the angel of the Last Judgement. Gabriel, known as Jibril, plays a similar role in Islam (he appears to Muhammad, and the revelations so transmitted are The Quran) and the Baha'i Faith.

He (and nowadays sometimes "she") is a Public Domain Character, from The Bible of course, though his status as an Archangel is never specified in the book itself.

Gabriel has commonly been depicted heralding messages with a horn, so the Horn of Gabriel may show up in fiction quite a bit. Said horn is often granted the epithet "Gabriel's Horn of Truth", and is occasionally seen as being used to herald the coming of the apocalypse itself. Gabriel himself is strongly associated with Seers, prediction and clairvoyance in his messages.

Because of meaningful names, most characters simply named Gabriel will generally be good guys. Since they are Gabriel In Name Only, please don't list them here.
