Raphael

Raphael aka The Healer first appears in season 5 ' Free to be you and me'. not much is known of him at the moment except he supposedly went AWOL after the last war and maybe the only one who knows where God is. It is for this reason Castiel is said to begin a quest of sorts to find him. Raphael is also one of the only four angels who has actualy seen God meaning he was probably very high up in the celestial heriachy.

It was stated that Raphael is chuck's Archangel, who killed Castiel in 'Lucifer rising'. as an archangel Raphael has imense powers. In episode 3 where he is supposed to appear Deam remaked his and Castiel's attempt to trap the angel in order to interigate him was like "Trying to catch a Huricane with a butterfly net" then Castiel said yes but a lot more dangerous. When Raphael did "touch down" his power blacked out the eastern sea bord. Raphael goes on to threatening castiel with death - despite his 'unending mercy', castiel replys that he would not dare as God was the one who brought him back and punish Rapheal for re-killing him. Raphael states however that Lucifer may have been the one to ressurect Castiel rather than god as "he need all the rebel angels he can get". He also threatens dean with something "imaginative" to force him into allowing himself as Michael's vessel. However dean states they knew he was coming, and traps Raphael in a circle of holy fire for interegation. When questioned about the whereabouts of god, Raphael states that "god is dead" , as that is the only possible reason for his 'abandonment' of the angels and the humans, leaving both races without orders or guidance. disheartened by gods desertion Raphael states the angels started the apocalypse, in order to defeat Lucifer and create paradise. when dean and castiel turn to leave Raphael demands to be realeased, when castiel refuses, Raphael swears vengence on him.

In biblical law Raphael is a healer and the writers of Supernatural have said this will cary over to the series, he also in biblical law defeated Azazel and bound him under a desert but it is unkown if this will be metioned in the series.
