Azazel

Azazel was a yellow-eyed demon and a confidant of Lucifer. On at least one occasion, Azazel has called Lucifer as his "daddy", a reference to Lucifer's role in creating demons. He was the murderer of Mary Winchester, mother of Sam and Dean Winchester.

He is referred to by nicknames such as "The Demon", "The Yellow-Eyed Demon", or "Yellow Eyes". The demon Casey did describe him as a tyrant who held the demons all together.

The only weapon described as having the power to kill Azazel is The Colt.

He killed Mary Winchester one night when she caught him feeding Demon Blood to Sam. This begins John Winchester's career as a hunter and dramatically changied the lives of Sam and Dean. John spent the whole rest of his life hunting Azazel, an obsession that Sam and Dean would inherit.

Personality
He is a demon with a sense of humor, he takes pleasure in seeing people suffer. The more pain, mostly psychological pain, the more pain he causes, the happier he is. He also is very talkative, talking continuously, even before finishing a fight. This flaw had failed him, since it gave Dean enough time to kill him.

Even for demons Azazel was cruel, as another demon described him as a tyrant. He was also highly manipulative, and cunning, able to twist others into doing what he wanted, he is so sure of his abilities he is even willing to put himself in harms way, just to help with it.

He however did keep to his deals and never tried to cheat a person, giving what he offered, and sticking to his terms.

Early Life
Having spent years searching, Azazel finally located the doorway to Lucifer's prison in 1972. The fallen angel tasked him with freeing the demon Lilith from Hell, she is needed to break the 66 seals holding Lucifer captive, and to find him a special children. By the following year, he began making demonic pacts with young individuals, in exchange for a wish, he would be allowed to enter

ten years later. Azazel eventually comes across Mary Campbell, the future mother of Sam and Dean Winchester. After taking possession of her father, Samuel Campbell, he kills her mother and stabs himself to kill his host. Mary's fiance, John Winchester, is the demon's next victim. However, Azazel makes his usual offer, giving her the chance to resurrect John, she reluctantly agrees.

In 1983, Mary discovers Azazel standing over baby Sam's crib, he had been feeding his blood to the infant. Upon being interrupted, the demon pins her to the ceiling, slashes her stomach and causes her to burst into flames. Mary's death inspires John to dedicate his life to hunting down Azazel, at the same time training Sam and Dean to hunt supernatural creatures.

Season 1
In "Dead Man's Blood," because demons cannot be killed by conventional means, the Winchesters track down the Colt, a mystic gun capable of killing nearly anything, including Azazel.

In "Salvation", they trace the omens caused by the demon's presence to Salvation, Iowa. Like he has done with Sam and countless others, Azazel plans to visit a six-month old and feed it his blood so the child will later develop demonic abilities. Although Sam interrupts the demon's plans and saves the family, Azazel teleports away to avoid being shot. Meanwhile, the demonic Meg Masters and her "brother" Tom kidnap John, and then set their sights on Sam and Dean.

In "Devil's Trap", An angry Azazel chastises them for killing Meg and Tom, he deems them his children, and begins to torture the brothers. John temporarily retakes control, giving Sam the opportunity to grab the Colt. Unable to kill his father, Sam shoots John in the leg, and the demon flees from his host.

Season 2
In "In My Time of Dying" John Winchester is summoning Azazel. When he came John aims the colt at him and tell him that he will give him the colt if he heals Dean. Azazel say that he can't heal Dean but he knows someone that can. He then tell John that there is something else he wants, John dead. Later Azazel take over the Reaper Tessa and heals Dean, then John gives him the colt then Azazel kills him.

In "All Hell Breaks Loose, Part 1", Azazel appears to Sam in a dream. In this twisted dream, the Demon informs Sam that he is in a contest against all the other "special children" like him. The Demon then notes that Sam is his favorite, so he shows Sam a vision of the night that the Demon visits him. It is shown that the Demon sort of "baptizes" the special children with his own blood, as sort of a ritual. Azazel also shows that Sam's mother, Mary, recognizes him and was only killed because she was at the "wrong place at the wrong time.

In "All Hell Breaks Loose - Part 2", he approaches Jake in a dream to tell him what to do now that he is the last survivor. He threatens Jake's family, and the soldier listens.

When Jake is asked by the Demon to do something for him, Jake is given the Coltthe Colt pointed at him and says that Jake would rather have health and wealth than to shoot the Demon. He promises security for his family as well, causing Jake to lower the Colt. With the Demon's pro and he immediately points it at the Demon. Feigning fear, the Demon shrugs off mises, Jake is coerced into entering the Devil's Trap and into using the Colt as a key to open a gate of hell.

The rush of demons from the gate opens the Devil's Trap so that the Demon can enter. When the iron lines are broken, he appears behind Dean and is about to be shot with the Colt, but telekinetically grabs it and forcefully throws Dean onto the ground, telling him how thankful he is to Dean that he revived Sam since he liked him better than Jake.

He also informs Dean that whatever Dean brought back is probably not "100% Sam" and taunts Dean that Sam coldheartedly shot Jake multiple times, a feat which he could not accomplish before. He then aims the Colt at Dean preparing to kill him, but John appears and grabs him from behind pulling him out of his human host.

Azazel escapes from John's grasp and returns to his body, but Dean already has the Colt and shoots him in the heart, killing him. Dean then triumphantly stands over the Demon's "body", recognizing he and Sam's victory over the thing which has given their family so much death and heartache. However, with the release of hundreds of demons, the Winchester brothers accept the fact that they have more work to do and more demons to hunt down and kill, possibly worse than Azazel.

Season 4
His "end game" was revealed in Season's 4 'Lucifer's Rising'. Azazel found the location of the final seal to free Lucifer. He possesses a priest and murders the nuns in the convent. Lucifer speaks to him through the body of a nun and tells him how to set him free. That he must first free Lillith, whom at this point is locked away in hell, and then find a special child to kill Lilith for the final seal to be broken (this is implied to be the reason why Azazel had Jake open the gate to hell) He also reveals in this episode that he is completely loyal to Lucifer, referring to him as his father (Lucifer also refers to him as his son). Whether he was really Lucifer's child or just that he was a faithful follower is unknown

The full scope of his powers is unknown. He mostly appears by possessing the bodies of others, and is only identifiable when he presents yellow eyes. He seems to possess telekinetic and pyrokinetic powers, which he uses elaborately to kill his primary victims. When not in possession of a body, he can exist as a black smoke, and at one point manages to dodge a bullet from Sam by teleporting. He holds considerable influence and power, he even at one point possesses a reaper and saves Dean's life. Unlike other demons on the show, he appears to be immune to exorcisms, holy water, and most other forms of defense against demons.

Season 6


In "Exile on Main Street", Azazel appears as a hallucination brought on by djinn poison. Upon seeing his face Dean is surprised and unsure what to do. He tells Dean that maybe God brought him back and continues to mock Dean. Dean passes out and Sam saves him. Azazel later appears when Dean is given a double dose of Djinn mojo. In this one, he is feeding Ben demon blood, telling Ben that it will make him strong.
