Raphael

"I know God's not around anymore, but I know he's not dead because if he died, the universe as we know it...would be gone."

-Raphael to Nathaniel about God

Raphael was the third of the four archangels created by God. He was older than Gabriel but younger than Michael and Lucifer. After Lucifer's rebellion and banishment, Raphael stood by Michael in taking over the Universe. He later changes his mind and helps Nathaniel and Raziel in saving the world.

History
The third archangel, Raphael lived happily in Heaven with his father God and his angelic brothers. With the Darkness existing alongside them, Raphael, his brothers, and God fought in a war against the Darkness, eventually winning the war by sealing him away.

When God created humans and asked all angels to bow down before them, Raphael was among those that did so. When Lucifer rebelled against God and Gabriel skipped out of Heaven and on to Earth, Raphael chose to side with God and Michael. However, at some point, Raphael lost faith in God and became weary of his father's duties. He knows that God is still alive, but believes he's either on an island somewhere with some hookers or not on earth.
