Castiel is the [[Angel]] who rescued Dean from Hell, according to Castiel on a command from God. His handprint is burnt into Dean's arm.
His true voice is piercing to the human ear and looking on his true visage will burn a human's eyes from their head, as [[Pamela Barnes]] found when she tried to summon him in a seance. When he mets Dean he is inside the body of a man he says "prayed for it".
