Lilith

Lilith was a powerful demon and Lucifer's second-in-command. She was the very first human to be turned into a demon. In fact, she was the very first demon that Lucifer ever created after Michael cast him out of Heaven and was thrown into Hell. Lucifer twisted and warped her soul as a way to mock God's most beloved creation: humanity, resulting in Lilith not only becoming a demon in her own right but also the final Seal, meaning that with her death, Lucifer himself would be released into the world.

She is a feared and ruthless demon, although Tammi refers to her as their Messiah. Though, she prefers her hosts to be young girls, she's been known to possess beautiful women in order to fool or seduce men. As she was the first demon created, she therefore became the final seal needed to release Lucifer from his prison in Hell.

Personality
Like most demons, Lilith serves to manipulate others for her own ends, even taking a human body, preferring young women and girls as her unwilling hosts.

She even has something of a sadistic nature when it comes to slaughtering or killing others. She also likes to torture and kill others, sparing no guilt and has no mercy for causing their deaths. Lilith also has the habit of having a child like way of talking, even when possessing grown women. In addition, she has a taste for infants' blood. She also seems to take extreme pleasure in psychological torture as well as physical, demonstrated as she plays along with the family of the girl she's possessing, forcing them to read stories to her and celebrate her birthday everyday while at the same time slaughtering anyone of them who "doesn't love" her. She also forces everyone who was in the police station to watch as she flays Nancy alive for forty-five minutes.

She seems to regard her followers as nothing but as means to an end as seen in "Lucifer Rising", when she mercilessly sacrifices some demonic-possessed people who are standing guard in an empty church as a part to bring Lucifer into the world.

As Lucifer's second-in-command and the first demon he ever created, she is generally loyal to her "father" and carries out his will without hesitation. Her loyalty does falter briefly when she learns that she has to die to bring about the apocalypse, causing her to attempt to make a deal with Sam and Dean. After this attempt fails, however, she recommits herself to freeing Lucifer and allows Sam to kill her in order to break the final seal. It appears that, unlike Azazel, Lilith does not seem to adore and worship Lucifer as he did, so it may be possible that ( like Alastair) she simply wants the apocalpse and wants the world to burn as she glories in the suffering of others.

Powers and Abilities
As a white-eyed demon as well as the first, Lilith is one of the most powerful demons, if not the most powerful. The fact that she is the first demon may mean she is stronger than high level demons such as Alastair and Samhain. Other demons all appear to revere and fear her for her capabilities. She is unafraid of normal angels, or at least she says she is, but when when confronted by an archangel, she will flee. It is unknown if her powers suppress those of Azazel who was a very high ranking demon and possesed many unquie powers, some that even she did not demonstrate, but it is possible as she is the first demon and she has less scene time. However as designer of the master plan, Azazel may hold more authority.


 * Demonic Possession - As a demon, Lilith can possess human beings, but she mostly likes to possess young girls, enjoying the experience. Sometimes, she possesses young, attractive women. She can also take over an occupied host, as she was able to force Ruby out of her host and possess it herself, something no other demon has been shown to do, however as Ruby was seceretly working for her, its possible she let her do it.
 * Telekinesis - Lilith has proven to have amazing telekinetic abilities. She can pin people to walls and break a human's neck without touching it. It is also stated that she was able to flay Nancy, the secretary, using her mind for forty-five minutes.
 * White Energy Blasts - Lilith can generate a demonic white energy blast from the palm of her hand that can destroy anything it touches. She was able to blow apart a police station by raising her hand. Sam Winchester is immune to this attack.
 * Reality Warping - Like a crossroads demon, Lilith can grant human's wishes if a deal is made. She also holds some of the contracts made by othe demons. She claims sexual intercourse is required to seal the deal with her rather than a kiss. It is unknown if her claim is true or if she simply wished to mess with Sam's head.
 * Control Over Hellhounds - Lilith has shown that she has can command Hellhounds and she can force them to do as she desires.
 * Teleportation- Lilith has proven that she can travel and appear anywhere in the world by teleporting to the locations she wants to be at.
 * Invulnerability - Being the first created demon, Lilith is a very difficult demon to kill. It's proven that she is invulnerable to weapons that could harm or repel most demons. The only things that can kill Lilith are Archangels, the Colt, or Special Children that have demon's blood and the power to kill demons. However, in order to kill her the special child would require the blood of an entire demon and extreme concentration. Lilith's death, however, gave Lucifer the freedom to walk the earth and leave his prison.
 * Immunity- It has been stated that she is immune to most demonic weaknesses such as Holy water.
 * Disintegration - Lilith was able to disintegrate a devil's trap by briefly touching it (though this could just be a variation of her demonic white energy).

Early Life
Lilith would cross paths with Bela Talbot. She made a deal with Bela: the demon would kill Bela's parents (Bela's father being abusive and her mother pretending that everything was fine) and guarantee Bela a large inheritance from their deaths in exchange for her soul ten years from the day they made the agreement.

According to the comic series Supernatural: Rising Son, Lilith came to the Earthly plane and assumed the human identity of Susan Lyle. As Lyle, she began masquerading as an elementary school teacher in Albuquerque, New Mexico. She endeared herself to her young student Sam Winchester, aware that Sam had a special destiny of some import to the forces of Hell. Dean was the first to determine Ms. Lyle's demonic heritage and their father John fought with her as well as a transmogrified construct near the railroad tracks.

Season 2
In "All Hell Breaks Loose - Part 2", Lilith secretly escapes from the Devil's Gate along with other demons while the Winchester were figthing Azazel

Season 3
Lilith is first mentioned by Tammi in "Malleus Maleficarum", Tammi makes the first reference to her - though not by name - she tells Sam that a new leader has risen "in the west", and wants to kill him.

In "Jus In Bello", it is revealed by Ruby that Lilith is the one that sent a horde of thirty demons to kill the Winchester brothers after they are captured by Special Agent Victor Henricksen and being held in the local sheriff's office. Ruby further explains that Lilith is more interested in killing Sam due to the fact that she sees him as competition. After the Winchester brothers successfully defeat the horde of demons and Henricksen lets them go, Lilith makes her first appearance. She arrives at the sheriff's office possessing a little girl accompanied by an adult woman, most likely possessed by a demon. Lilith walks over to Nancy Fitzgerald, the secretary of the sheriff's office, and tells her that she's looking for two boys and that they're brothers, "one's really tall" and "one's really cute". Nancy asks what Lilith's name is. Lilith tells her that her name is "Lilith" and then reveals her white demonic eyes. Before, Nancy, Henricksen, or the deputy could do anything, Lilith raises her hand releasing a burst of white energy causing everyone in the sheriff's office to scream in agony. Later on, Ruby has the Winchester brothers turn on the news to see that Lilith not only killed everyone in the sheriff's office but blew up the building as well.

In "Time Is On My Side", after it is revealed that Bela Talbot made a deal with a Crossroad Demon ten years ago, she reveals that she used the Colt to bargain with the demon that holds her contract but it wasn't enough. The demon wanted her to kill Sam too. Dean then states that they could have helped her, if she had only been honest with them. She reveals that it is Lilith who holds her contract and Dean's as well, and that Lilith is the one who wants Sam dead. When he asks her why she is telling him all that, she replies that she wants them to kill Lilith.

In "No Rest For The Wicked". With the assistance of Bobby Singer and Ruby, Sam and Dean discover that Lilith is in New Harmony, Indiana; on what Ruby refers to as ‘shore leave’. In this middle-class suburb, two elderly Gentlemen are talking when one hands the other a folded note with the words ‘Help Us’ inscribed. This man then proceeds to enter his house, where a corpse of an elderly woman is seen rotting on the hallway floor. He enters the kitchen where he speaks to a man and a woman, who are preparing for a birthday party. He tries to warn them that they must flee before ‘it’ kills them. The woman is hesitant; she insists she cannot abandon her child; the second man (the child’s father) beckons the mother to be quiet; footsteps can be heard coming down the stairs.

A small girl enters the room her dress drenched in blood; she demands that they tell her what they were discussing. The mother counters her request by asking what happened to her dress. To which the child states that the family pet ‘Freckles’ was “mean to her”. Clearly disturbed by this event the father asks his daughter if she will release the family; the girl’s demeanor become icy - she wants to know why they want to leave. She suggests menacingly that they don’t love her anymore and that they shouldn’t upset her unless they want to share the same fate as the Grandmother. Realizing that their powerless to resist, they apologize to her; she forgives them and then asks her father to play with her outside.

Later that day the family gathered around the Dining room table; where they are celebrating the girl’s birthday. As the mother places the birthday cake on the table; Lilith demands to know why the Grandfather asked the neighbor for help. The family display looks of sheer terror, their plan has been foiled. He feigns (rather unconvincingly) innocence; Lilith calls him a liar and then turns her attention to the parents, demanding they tell her the truth. The parents plead ignorance, and lie to her claiming they had no knowledge of the Grandfathers deception. The Grandfather pleads for help, but to no avail, Lilith then uses Telekinesis to snap his neck.

Sometime later that evening Sam and Dean enter the house, Sam is about to kill the girl, (who is asleep, her mother is awake beside her). The mother pleads with Sam to kill the child as Sam approaches but Dean calls him off; he knows Lilith is no longer using the child as her host. Sam turns to Ruby, who has followed the boys, for help again, but she says it is too late to save Dean. As the Hellhounds come for Dean, the boys barricade themselves in a room. Dean, who is able to see the true face of demons, realizes that the body Possessed by Ruby now contains Lilith. She pins Sam to a wall, and Dean to a table. She says Sam no longer has anything she wants, and makes him watch as the hellhounds tear Dean to pieces. She then turns her power on Sam, but it has no effect. He takes Ruby's knife, and is about to kill Lilith when she abandons the body.

Season 4
In "Are You There God? It's Me, Dean Winchester", Castiel tells Dean that when Lilith released the Witnesses, she broke one of the sixty-six seals, and that when the last one is broken Lucifer will be freed.

In "Yellow Fever", Lilith appears to Dean in the form of the little Fremont girl she possessed in No Rest For The Wicked as a hallucination and taunts him about dying all over again. She reminds him of his time in hell, saying four months was more like forty years in hell.

In "The Monster at the End of This Book", Lilith appears as an adult woman, possessing the body of a dental hygienist from Bloomington, Indiana. Sam and Dean have been warned of her arrival by the author and prophet Chuck Shurley. He also forsees a "night of fiery demonic passion" between Lilith and Sam. Dean wants them to avoid Lilith, but Sam is keen for a confrontation.

Eventually, Lilith confronts Sam in his hotel room determined to make a deal; she will stop breaking the seals (that bind Lucifer in Hell), in return for Sam and Dean's lives. Sam is reluctant at first; he questions Lilith's motives as to why she has had a change of heart. Lilith tells Sam that apparently she dies before the apocalypse is set in motion - this is why she wants to make a deal. Sam reluctantly agrees to Lilith's terms; however Lilith tells Sam that the deal has to be consummated before they are bound to its terms.

As Sam embraces Lilith on the bed he grabs Ruby's knife in order to kill her; however she overpowers him and seizes the knife. Dean and Chuck abruptly enter the room, with Dean demanding that Lilith leave, before the Archangel (possibly Raphael) who protects Chuck comes and kills her. As the room is slowly being engulfed by light, Lilith heeds Dean's words and departs from the body, leaving it motionless on the floor.

Later Dean asks Sam whether he would've taken the deal, but Sam says no, because Lilith would've found some way to "weasel out of it." He does note that she's scared and that she was right about dying before the apocalypse because he'll make sure of it.

In "When the Levee Breaks", Ruby tells Sam that Lilith is "Lucifer's first" - the first demon created from a human, and the only one who can break the last of the The 66 Seals.

Finally in "Lucifer Rising", Lilith's death is revealed to be the final seal, the one which will free Lucifer. This has only been known by the higher ranking Angels - who want the apocalypse to come, and by Lilith and Ruby. Ruby has been manipulating Sam to get him to kill Lilith. However after Castiel learned the truth he saved Dean from the angels and sends him to stop Sam. Sam however uses his powers to kill Lilith and breaks the final seal, freeing Lucifer. Ruby is later killed by Sam and Dean after being revealed to be an double agent.
