Intro. Like an angel, seeing Castiel's true form will result in blindness, as the appearance of his natural face is so great that it is capable of burning human eyes or demon. However, Castiel stated certain, "special people" are able to tolerate his true appearance and voice. Although his true form has never been seen, it is known that he has two wings of penalties and his true form is approximately the size of Chrysler Building.
