Castiel

History
Castiel is an angel of the Lord who was ordered to pull Dean Winchester out of Hell and help him with his mission to stop Lilith from breaking the 66 Seals that would release Lucifer. He seems to be very mysterious and introspective about his assignment from God. In "It's the Great Pumpkin, Sam Winchester", Castiel revealed to Dean that his directives are to take orders from Dean himself. Sam Winchester was initially in awe of Castiel, for which he is instantly snubbed as being exposed by Castiel by having demon blood and for using his abilities, which are strictly forbidden due to their demonic origins.

Castiel appears to be impervious and resistant to all know forms of spells and hexes, as he effortlessly passed by all the seals that Dean and Bobby Singer scribed inside the warehouse where they all formally met (seen in the attached picture). The human vessel he chooses to inhabit is named Jimmy Novak.

Dean bears a handprint, or the "Mark of Castiel," on his shoulder as a verification and reminder that Castiel physically pulled him out of Hell. In "Are You There God? It's Me, Dean Winchester", Castiel threatened to put Dean back if he doesn't aggressively proceed in his mission to prevent the release of Lucifer. The validity of this threat is unsubstantiated as he revealed that his mission is to follow Dean's orders; more than likely a psychological tactic to motivate Dean.

Although he is an angel, Castiel has admitted certain limitations to his abilities while on Earth. His signature power appears to be instant teleportation, as he is able move effortlessly from one point to the other in the blink of an eye. It is also revealed that any human who was to hear Castiel's true voice would suffer a terrible death, and the only known person to have been able to withstand it was his vessel, Jimmy Novak, as he was communicating with him before taking over his body.

Castiel's physical appearance seems to be that of an average human male who is returning from a hard day's work in an office environment. He sports a pair of dress shoes, dress slacks, unbuttoned white-stripped dress shirt, and loosened necktie accentuated by a beige trenchcoat. Although he has a very dire demeanor, his outward appearance radiates a natural calm and serenity, which makes conversation easy and direct.

Castiel and his fellow angel Uriel make mention of a conversation (which is reminiscent of dialogue in the movie The Prophecy starring Christopher Walken and Eric Stoltz) in relating God's relationship to mankind and the majority of the angelic population being very jealous of humans' ability of free will, as they were considering destroying a town in "It's the Great Pumpkin, Sam Winchester".

NOTE: In folklore, Castiel is the Angel of Thursday, possibly chosen to be a character in Supernatural because it airs on Thursday nights.

Unlike most angels seen in the show, Castiel is interested in humans and is fascinated by the aspects of humanity, such as free will, while other angels like Uriel or Lucifer look at humanity as inferior or with contempt. Castiel also has a respect for God that many other angels in the show don't seem to show, possibly due to the fact that none of them has seen or heard from God in so long and they feel they have been abandoned. Castiel admitted that while he sometimes questions his orders, he will always follow his Father.

Older angels look at Castiel's interest in humans and faith in God has an unhealthy interest and naive belief. Anna Milton called him a hypocrite for believing he could help humans and serve God at the same time when he refused to rebel in order to gain more freedom. Lucifer was disturbed when Castiel showed more concern for his failing vessel than any reaction to the sight of the fallen Archangel himself. Lucifer attempted to convert Castiel to his side, saying he would be a target of hate among the other angels and his Father because of his actions; Castiel responded that while he may have deviated from traditional angel behavior, he would rather die than betray his Father and become what Lucifer was.

Additionally, Castiel is fairly young by angelic standards, though he claims to have met the prophet Luke who was apparently no better than Chuck Shurley in lifestyle and personality. Discussions with Uriel suggest the pair were children by angel standards when Lucifer instigated the first War in Heaven. While Uriel was instantly enthralled by Lucifer's power and charisma, Castiel remembered being frightened and disturbed by the rogue angel.
