Balthazar

Balthazar was an angel of heaven, as a crossroads angel that took the Staff of Moses (in addition to all of Heaven's other weapons). Balthazar then breaks the Staff of Moses into several pieces, allowing him to acquire many souls as opposed to selling the Staff in one complete piece and only acquiring one soul for it.

He was thought to be dead in the Apocalypse as Castiel mentioned, but Balthazar revealed he faked his death to follow in Castiel's "shoes", meaning he left heaven so that he may live his life without the constraint of Heaven's orders.

Personality
Balthazar lives in Ashtabula, Oh.

Power and Abilities
Balthazar's powers and abilities are similar to those of other angels. Balthazar is able to influence the movement of objects and people using his mind. He can also teleport himself and others through time and space. He is able to manipulate time. He can also overpower humans and demons.

Early Life
Balthazar fought alongside Castiel and Uriel. Castiel thought that he had died in battle. In fact, Balthazar faked his death to hide his departure from Heaven, and took a number of powerful artifacts, including the Staff of Moses and Lot's Salt, with him. He has been on Earth enjoying a rather hedonistic lifestyle.

Season Six
When Castiel, Sam and Dean inflitrate his mansion residence after reading his angelic signature left on a boy's ribs. Balthazar had made a bargain for Aaron Birch's soul, playing the role of an angelic crossroads dealer. Castiel confronted the angel, in shock that his friend had not fallen during the Apocalypse like he had thought. As it turned out, Balthazar had faked his own death and stolen several Biblical items from Heaven to avoid being killed for real due to the total anarchy "upstairs".

Castiel tried to bargain with his old friend for the release of the child's soul, but Raphael and his angels interrupted before anything could be agreed upon. Balthazar disappeared just as Raphael infiltrated the mansion and left Castiel to fight him alone. Raphael continues to thrash Castiel, but before he could deliver the final strike, Balthazar returns with a crystal-shaped weapon and turns Raphael's vessel into salt, forcing him to find a new host, adding that "the same thing happened to Lot's wife".

Amazed that he had returned, Castiel stands to thank him, but Sam and Dean arrive and trap him in a circle of holy fire. When they refuse to release him, he calls Dean a "hairless ape" and turns to Castiel for help, who says only that "the hairless ape has the floor." The brothers agree to let Balthazar go after he returns the child's soul. The angel agrees and makes void the contract between the boy and himself, but will not return the weapons. Sam threatens to douse him in holy fire, but Castiel releases him before either of the brothers can do anything, saying that his debt to Balthazar, for saving his life, had been cleared.

Sam summons Balthazar to find a way make his body reject his soul. Balthazar agrees to help Sam, just to piss off Dean. He also mentions that he would very much enjoy having Sam indebtted to him. Balthazar tells Sam that in addition to a few easily aquired ingredients, he needs to commit an act so vile, that it permanently "scars his vessel". When Sam inquires as to what that is, Balthazar informs Sam that he needs to commit patricide (i.e. killing his father).

Sam immediately states that his father John has been dead for quite some time now, to which Balthazar responds saying "You need the blood of your father, but your father need not be blood". It is now made obvious to Sam that Balthazar is implying that the death of Bobby will suffice, considering Bobby has been the closest thing to a father for Sam since John's death.

Balthazar suddenly appears at Bobby's house and tells Sam and Dean that Raphael intends to kill everyone who ever helped Castiel. He does not explain the situation, but quickly starts gathering Dead Sea brine, lamb's blood, and the bones of a lesser saint, which then he uses to draw a sigil on a window. He gives a key to Sam to guard and then Virgil, Raphael's angel assassin, arrives, so Balthazar quickly tosses Sam and Dean through the window, sending them to a different universe.

Later it turns out that sending the Winchesters into a different world with a bogus key was part of Balthazar and Castiel's plan to divert Raphael's attention from what they were really doing. While Virgil and Raphael were focused on Sam and Dean, Balthazar was able to gather the stolen weapons of Heaven and give them all to Castiel. When Raphael arrives to kill Balthazar, Sam, and Dean, Castiel appears and threatens Raphael with the weapons now in his possession, forcing him to leave.

Balthazar alters history and unsinks the Titanic. Balthazar asserts that his reason for doing so being that he hated the movie, and that the theme song by Celine Dion made him want to "smite himself". With this action, it alters history and creates thousands of new souls. Because of this intervention, Atropos, the sister of fate in charge of "snipping the thread of life" begins to try to undo the mess created by this.

Atropos begins to try and kill Dean and Sam for two reasons, to spite Castiel and because them stopping the apocalypse ruined her work and made her obsolete (because now, no one is bound by fate and everyone has freedom). After a brief confrontation between Atropos and Castiel, Balthazar approaches from behind to kill her. n the end, Castiel gives Balthazar orders to cease his attempt to kill the Sister of Fate, and to go back in time and allow the Titanic to sink, setting the events of time back to the way they are supposed to be.

In Let It Bleed, Sam and Dean summon Balthazar for help on finding Lisa and Ben. When summoned, he tells the boys to stop calling him. Sam and Dean reveal to him that Castiel is working with Crowley, but Balthazar already knew that. They then reveal that Castiel plans to open Purgatory, which Balthazar pretends to know about and then disappears. Balthazar later asks Castiel if his plan to open Purgatory is indeed true. Castiel confirms this and asks Balthazar if he's still with Castiel. Balthazar lies and tells Castiel that he is still loyal. Balthazar returns to Sam and Dean, now agreeing to help them. He finds and takes Sam and Dean to the location and vanishes.

Balthazar continues to help them in The Man Who Knew Too Much. He compliments Dean on finally angel proofing the panic room correctly. When Dean first asks Balthazar about Castiel and Crowley's location, he is resistant, describing his confliction on whether or not he should betray his angelic friend and help the brothers. After some slight hesitation, Balthazar eventually gave Dean Castiel and Crowley's location and vanished. Unfortunately, Balthazar has not yet realized that this act of helping Dean and betraying Castiel had already cost him his life.

Castiel summoned Balthazar to his hideout and told Balthazar there is a "Judas" among them. Castiel asks Balthazar to go and find the tratior, and Balthazar attempts to play dumb, even trying to direct the blame onto another angel, going as far as to say "I bet it's that bloody Cherub, isn't it?". At this point, Balthazar is not aware that Castiel already knows that he is the traitor in question. Balthazar continues to attempt to alleviate Castiel's concerns by saying "well, you always have little old me". Immediately afterwards, Castiel appears behind Balthazar and stabs him while saying "yes, I'll always have you". Balthazar's last moments are of shock and confusion right before he dies seconds later.

 * Balthazar is the first character in all of season 6 to comment on how valuable and how powerful human souls are.
 * In You Can't Handle The Truth, Castiel mentions that the "Horn of Gabriel" which makes anyone tell the truth is stolen from Heaven. It is never proved but is very possible that Balthazar had stolen this along with the other weapons.
