Zachariah

Zachariah was an angel of the Lord and Castiel's superior. He shows Dean Winchester in "It's a Terrible Life" that hunting is in his blood. He appears again in "The Monster at the End of This Book" to tell Chuck Shurley that he's a prophet chosen by the Lord. Zachariah is revealed to want the apocalypse to occur, because he thinks Heaven will easily win. This was revealed in Lucifer Rising. He is a bit wary of humans, describing them as "smelly things". Despite this he has proven himself to know a great more about humanity than his inferiors, and even acts much more human, with a sharp wit and cheerful exterior.

Powers
The only power that Zachariah has demonstrated is the power to alter reality, although it is not known if he is the one who actually created the alternate reality in "It's a Terrible Life". In "Lucifer Rising" he teleports Dean to what appears to be an art museum that he has filled with beer and various foods to keep Dean safe and relaxed while he awaits his role in stopping the apocalypse. He even offers Dean a threesome with Mary Ann and Ginger, which Dean doesn't hesitate to refuse. He possesses such abilities as breaking a bone in someone's body with a point of his finger, giving someone varying levels of cancer, and removing lungs from someone's body.


 * Alternate reality (Signature move)
 * Teleportation (It is possible that Zachariah taught Castiel this ability)
 * Invulnerability (Zachariah possess a high degree of Invulnerability)
 * Telekinesis
 * Angelic possession
 * Telepathy
 * Time travel (Zachariah proved to be capable of sending people into the future)

Other
Zachariah hasn't displayed any type of superhuman strength. He may posses this ability but he hasn't demonstrated this yet. He has yet to display his superhuman stamina and endurance.

In Heaven, and therefore assumedly in his true form, he has six wings and four faces, one of which is a lion. That description possibly implies that he's a hybrid of a Seraphim and a Cherubim.

Death
Zachariah met his fate trying to redeem himself. Being constantly laughed at because he cannot catch the Winchesters, he resurrects Adam, the Winchester's 3rd brother, because he was chosen to be the temporary vessel for Michael. However, Sam and Dean confront Zachariah moments before Adam consents. Zachariah easily takes out Sam, but gets worked up over Dean's remarks. Dean conceals an Angel Blade and stabs Zachariah, killing him.
