Castiel - Supernatural
Castiel is an angel who pulled Dean Winchester out of hell at the beginning of season 4 of Supernatural. Although it has been suggested angels do not possess the ability to feel emotion, Castiel frequently exhibits friendly affection towards Dean, and it has been admitted that he has a profound bond with the human.
(The wings are meant to be transparent looking, and the best I got, seen as Seraphim wings cost upwards of 4 mil. Also I am shocked no one has ever cosplayed this guy before!)
