Lucifer

"You know why God cast me down? Because I loved him. More than anything. And then God created...you. The little...hairless apes. And then he asked all of us to bow down before you—to love you more than him. And I said, "Father...I can't." I said, "These human beings are flawed, murderous!" And for that...God had Michael cast me into Hell. Now, tell me...does the punishment fit the crime? Especially when I was right? Look at what 6 billion of you have done to this thing. And how many of you blame me for it?"

- Lucifer, speaking to Dean Lucifer, also known as The Devil and Satan, is a fallen archangel. He is the former ruler of Hell and the creator of demons seen by them as a father figure. As the second-born archangel, he is the younger brother of Michael and the older brother of Raphael and Gabriel. According to Gabriel, he was God's favorite celestial, but when God asked for all angels to bow down to humanity, Lucifer refused. He waged a war against God but was banished to Hell by Michael. All of Azazel's actions were motivated with the goal of eventually releasing Lucifer.

Since he is an angel, Lucifer must have the permission of any human he wishes to use as his vessel, as he can not forcefully possess a person. Being an archangel, Lucifer possesses much more power than any normal angel and also every demon, most of whom deify him.

He was finally freed and allowed to roam the Earth when the final seal (the death of Lilith) was broken by Sam. Freed from his cage, he took action to bring about the Apocalypse and cleanse the Earth (aka "The last perfect handiwork of God") of human beings (the flawed creation). Even after Lucifer was able to possess his true vessel, Sam's love for his brother Dean allowed Sam to regain control of his body, and seal himself, Lucifer, Michael, and Adam Milligan in Lucifer's Cage.

Lucifer is the main antagonist of Season 5 and the secondary antagonist (as a hallucination) of Season 7. He is arguably the primary antagonist of the entire series, having served as the ultimate cause of evil in the show.

Origins
Lucifer was the second archangel that God created, and was then raised by his older brother Michael in Heaven. Lucifer was at one time the favorite of God's angels, and his name translates to "The Light Bearer" or "The Morning Star." It was stated that he once had a strong relationship with God and was fiercely loyal and devoted to him. When God created mankind and commanded that his angels honor humans by bowing to them and loving them even more than God himself, Lucifer refused to do so. Being full of pride, Lucifer refused to bow to a creature that he considered lesser than himself. Deciding to wage a war against God, Lucifer approached his older brother, the archangel Michael, hoping his elder sibling would stand by his side during the rebellion. Michael rejected him, and stood by his father, and a war begun in Heaven. After Lucifer lost the war, God cast him out of Heaven, and he fell to Earth. Sometime before he fell, he somehow came into possession of the angel tablet, which can only be read by the prophet Kevin Tran and the angel Metatron.

Once on Earth, Lucifer created crypts, and hid various items (including the angel tablet) in them. As his rage against humans grew, Lucifer eventually approached the Garden of Eden and convinced Gadreel, God's most trusted angel, to let him into the garden. Once in the Garden of Eden, Lucifer went to Lilith (the first wife of Adam) and twisted her soul into the first demon. God replaced Lilith with Eve, so that humans (his favorite creation) could reproduce and live. Lucifer, still in the garden, twisted their minds, and got them cast out of the garden. After this, God created Hell, and had Michael cast Lucifer into it, along with Lilith. Sometime later, Lucifer managed to escape Hell, and manipulate Abel (the second son of Adam and Eve) into listening to him rather than God. In fear for his brother's soul, Cain made a deal with Lucifer asking for Abel to ascend to Heaven in exchange for Cain going to Hell, but Lucifer only agreed if Cain was the one who killed him. Cain agreed, and Lucifer bestowed him with the Mark of Cain. The Mark eventually changed Cain into a powerful demon who personally created and trained the Knights of Hell, an elite order of demons hand-picked by Lucifer himself out of the very first demons.

Because Hell could not contain the archangel, God decided to created a personal cage for him in Hell, locked with 600 seals. Lucifer's actions caused the Earth to be cursed with evil, and Hell eventually became the painful resting place for all those he had corrupted where they would be tortured endlessly forever until transformed into demons.

Once in his cage, Lucifer became associated with, and was often referred to by, the name "Satan." The word "Satan" literally means "The Adversary" or "The Accuser". Despite being sealed away, he was still considered the ruler of Hell and the lord of all demons. The cage that Lucifer was imprisoned in was designed so that he could never leave or escape it on his own, and it was then further locked with 600 powerful seals. Any 66 of those 600 seals would have to be broken by an outside being in order to free Lucifer. The seals served to bind Lucifer's power and to keep him from escaping his new prison in Hell. Of the 66 seals required to free Lucifer, only 2 of them are required in a specific order. The first seal is quoted by Alastair as, "And it is written, that the first seal shall be broken when a righteous man sheds blood in Hell. As he breaks, so shall it break." The final seal is quoted by Ruby as "And it is written, that the first demon shall be the last seal." Aside from those two seals, any other 64 of the remaining 600 seals will suffice.

Azazel's special children
During his long imprisonment within the confines of his cage in Hell, Lucifer was served by his many demons, one of the most prominent being his confidant, the Yellow-Eyed Demon known as Azazel. None of them had truly seen Lucifer, as he was locked away in a special part of Hell that had only one entrance kept locked by the 66 seals; this left the vast majority of demons without hope that they would ever find Lucifer and return him to power, save for one demon in particular: Azazel, who eventually escaped to the Earth in search of a way to free Lucifer from Hell.

In 1972, years after leaving Hell and wandering the world, specifically the desert, for years in search of the entrance to Lucifer's Cage, Azazel discovered the location of Lucifer's prison in one of the most ironic of places: a convent. He possessed the body of the chief priest of the church, St. Mary's Convent, in Ilchester, Maryland (the location where Lucifer would eventually be released), and pretended to carry out the priest's current mass, with an audience of eight nuns in attendance. Eventually, the priest's words began to speak of a different Father, Lucifer, and the priest was then revealed to be Azazel, who then proceeded to slaughter the nuns.



After they were dead and the church was left a bloody mess, Azazel, still possessing the priest's body, spoke directly to Lucifer himself, who in turn spoke through the body of a nun. Azazel stated his great relief to hear Lucifer's voice once again after so many ages. Lucifer commended Azazel's unshakable faith in him and stated that he had done well to find him. Azazel then requested knowledge of what was binding Lucifer in Hell and how he could help Lucifer break free and rise once more. Lucifer then told Azazel that Lilith was the only one who could break the seals which bound him to Hell.

Revealing that Lilith would have to be freed from Hell and then sacrificed by a special child with psychic powers strong enough to perform the deed, Lucifer entreated Azazel to devise a way to break this seal and set him free. It is here that Azazel is revealed to be ultimately loyal to Lucifer and that his endgame throughout the series has been the release of Lucifer from Hell. With Lucifer's location now confirmed and knowing what he had to do in order to release him, Azazel departed his meeting with Lucifer with great hope and a plan in mind to fulfill Lucifer's release from Hell.

The Release of Lilith
Armed with the knowledge of the 66 seals, Azazel crafted a plan to break the final seal by finding the prophesied special child that would be strong enough to kill Lilith when the time came. He also devised a plot to break Lilith out of Hell at the right time. In search of the special child spoken of by Lucifer himself, Azazel began to search far and wide for parents sure to bear children with certain psychic abilities if properly activated. To this end, Azazel would typically blackmail the parents of the child in question, by means of quid pro quo, into allowing him to visit the child in question upon the night of their six-month birthday, as he would ordinarily be unable to enter without their permission. What Azazel did not reveal to the parents, however, was that he would bleed into the mouth of the child, feeding them demon blood and activating/creating their psychic powers. He did this with many children, knowing that one day he would have to determine which would be powerful enough in the end to kill Lilith and release Lucifer from Hell.

Azazel finally learned of a way to release Lilith from Hell, by means of a portal connecting the Earth to Hell called a Devil's Gate. After discovering the Devil's Gate to be protected by numerous backups including a one hundred mile Devils Trap set in place by the legendary Samuel Colt and that the key to the gate was the gun created by Colt himself, Azazel began to also search for this key and found another use for the special child he sought: to pass through the barriers Colt had set in place around the Devil's Gate and open the gate itself once the key had been located.

Season 3
The demon Casey claims that demons have a belief system just like humans, but while humans believe in God as a higher power, demons view Lucifer in the same regard. Casey tells Dean Winchester that Lucifer was once an angel, and that his name means "light-bringer." Casey also states that no demon has ever actually seen Lucifer.

The Breaking of the 66 Seals
Dean is dragged into Hell by Lilith's Hellhounds at the end of the third season - this is due to the bargain with the Crossroad Demon to revive Sam in exchange for his soul. Dean spent four months of Earth time in Hell (around 40 years in Hell time) and for the first thirty of those forty years, the chief executioner of Hell, Alastair tortured Dean daily and offered to stop his torture if Dean himself would torture other souls trapped in Hell. Dean refused the offer each time; however, after thirty years of pain and misery, Dean began to crack and finally could take no more, and so he accepted Alastair's offer, getting out of his own torture and taking up torturing other souls for a total of ten years.

Dean did not know that this was the first seal that bound Lucifer in Hell, and that as long as the true first seal remained intact, the others could not be broken. This had been Lilith and Alastair's plan all along: to force Dean, a righteous man, to crack under torture and begin torturing other souls to spare himself from further torment. From the moment Dean first began torturing souls under Alastair's tutelage, the first seal binding Lucifer was at last broken, enabling Lilith and several hundred demons now on Earth to begin breaking others in order to release Lucifer from his prison.

The fourth season of the series chronicles the efforts of Lucifer's demon minions to break the other seals. The seals operated as locks on a door. Some of these included the Rising of the Witnesses, the summoning of Samhain, and the sacrifice of two Reapers under the Solstice moon. Although there were over six hundred seals in place, only sixty-six needed to be broken in order for Lucifer to escape his prison. There was also a stipulation in the initiating and ending of the process of breaking the seals: The first seal and the final seal had to both be satisfied regardless of what other seals were broken. The first seal, which had to be satisfied before the others could then be broken, was the cracking of a righteous man in Hell. Dean broke this seal unknowingly during his imprisonment in Hell, he is rescued soon after, before he is recruited, along with his brother Sam, to fight against Lilith's forces to save the other seals from being broken. As it was nearly impossible to know which Seals Lilith would choose to target, it was also next to impossible to stop her from breaking others.

Sam was also slowly turned into a demon-blood addict by the demon Ruby as she prepared him to fulfill his own secret role in Lucifer's release: carrying out the execution of Lilith and becoming strong enough to take his place as Lucifer's vessel. Finally, near the end of the fourth season, only the true final seal remained: the death of Lilith herself. Lilith had planned out the breaking of the seals, and once sixty-five of them were broken, she prepared to play her own personal role in Lucifer's release, to die in order to ensure the release of her creator and the coming of the Apocalypse.

The Rising of Lucifer
By this point, Dean had been rescued from Hell by the angel Castiel, who had hoped to rescue Dean before he gave into his torture in order to prevent the first seal from being broken, and Sam had honed his demonic powers with the help of Ruby, who had been preparing Sam to be able to battle and kill Lilith (convincing him that this would prevent the final seal from being broken and as an act of revenge for Lilith sending Dean to Hell in the first place). What Ruby did not confide to Sam or his brother, however, was that the truth was just the opposite: Lilith must die, as her death was the final seal necessary to be broken in order to fully release Lucifer, something Lilith herself already knew and was willing to undertake.

By the time Dean realized this and escaped confinement by the angels (who wished to confront the demons and Lucifer in the Apocalypse so as to ultimately defeat them and bring about paradise on Earth), he was too late to warn Sam that killing Lilith would, in fact, ensure Lucifer's release rather than prevent it. Sam was torn for a moment between listening to Dean's cries to stop and Ruby's screams for him to kill Lilith, but when Lilith mocked him, that overrode all else. Sam killed Lilith with his powers, and Ruby then goaded him for having in fact caused the Apocalypse rather than having stopped it, revealing she had been working with Lilith the entire time and that Lucifer himself had foretold that only Sam could kill Lilith. Dean killed Ruby with her own demon-killing knife, but the Winchester brothers watched together in horror as Lilith's blood revealed the mouth of Lucifer's Cage, which began to open, allowing the Devil himself to rise out of his prison.

As the gate to Hell fully opened and Lucifer's true angelic essence began to ascend out of the cage to Earth, the brothers attempted to flee, only to have the chapel's doors slam shut and lock. Seeing that running was futile, they turned and watched in horror as the portal opened and the Devil's piercing true angelic voice rang through the church. Though they fell to the ground in pain, God personally intervened to save the brothers from Lucifer's rising by teleporting them onto a plane passing over Ilchester at that moment, from which they watched as Lucifer's essence shot up into the sky from where St. Mary's Convent stood, blowing it apart. This signaled the beginning of the Apocalypse.

Preparations for the Apocalypse
Now free, Lucifer set out to find a vessel, someone Lucifer could take control of in order to walk the Earth. Lucifer's chosen vessel turned out to be a lonely man named Nick, whose wife and baby were killed by an intruder who broke into their home one night. Lucifer began to manipulate and mentally torture Nick, making him start to see things in his sleep, like mass amounts of blood dripping out of his dead child's crib, hearing his dead child crying through a baby monitor, and making his child's swing move without apparent cause.

Lucifer then appeared in Nick's dream again, taking the form of his dead wife to communicate with him. Lucifer explained to Nick that he needed his permission to take over his body, but Nick refused. Lucifer then told Nick some of his origins, such as how he loved God "too much" and felt that though God created them that He should not be allowed to "toy" with them. He went on to further manipulate Nick, explaining that God didn't do anything to stop the death of his family, making Him either sadistic or meaning that He simply didn't care. Lucifer then tempted Nick, saying that it was God's fault that his family died and that if he allowed him to take over his body, he would make sure justice is served. Nick agreed, and in a burst of bright light, Lucifer took over his vessel, regaining much of his former strength and full corporeal form.

In Free To Be You and Me, Lucifer appeared to Sam in the form of his deceased girlfriend Jessica Moore, telling him that no matter how many times he runs away he will always be part of the supernatural, people that get close to him will get killed, that there is no hope for him. The next night he appeared to Sam as Jessica once again but when Sam said there was hope for him, Lucifer dropped the masquerade and appeared in Nick's form and told Sam that Nick was simply a "plan B" because Sam is his true vessel. Lucifer states that he will never lie or trick Sam into saying Yes but he will do so willingly before disappearing.

In The End, Zachariah finds Dean and sends him five years into the future so that Dean can see the repercussions which will follow if he refuses to be Michael's vessel. In the year 2014, Dean travels with the older version of himself, and a group of other hunters, including Castiel, to Detroit to confront the Devil. In this future, Sam consented to serve as a vessel, and the world is ending. Future Dean tries to use the Colt on Lucifer, but the archangel snaps Future Dean's neck with his foot. Lucifer, wearing Sam, turns around and sees the Dean of the past and tells him that he does not want to destroy the world, but to rid it of an imperfection. He insists that he was unfairly cast out though Dean doesn't fall for Lucifer's sob story. Lucifer also tells Dean that Sam will always consent to him in Detroit; no matter what they do, Sam will become his vessel and the two will always meet up in this position. Zachariah then retrieves Dean and he returns to his current year.

In Changing Channels, Gabriel reveals to Dean and Sam that they were, since the birth of humanity, destined to be the vessels of Michael and Lucifer respectively. While noting comparisons between the Winchester brothers and the two archangels, Gabriel states that their relationship mirrors Michael and Lucifer's.

In Abandon All Hope it is shown that Nick's body is beginning to decompose and deteriorate, as he cannot properly contain Lucifer's angelic essence. Lucifer's physical angelic complexion proves overwhelming to a normal human vessel that is not their true, pre-destined vessel (like Sam is for Lucifer). True vessels give archangels a full corporeal body to manifest in while on the Earth. Lucifer is in Carthage, Missouri on a mission to summon Death, one of the Four Horsemen of the Apocalypse. Sam and Dean plan to fight him and the demon Crowley gives them the Colt to kill him believing that Lucifer intends to destroy demon kind once humanity is gone. He manages to trap Castiel inside a ring of Holy Oil, and his demons trap Sam, Dean, Jo, and Ellen. Lucifer speaks to Castiel, asking him whether he came with the Winchesters. Castiel lies that he came alone, but Lucifer is not fooled, though he admires the other angel's loyalty. Castiel asks about his vessel, which is breaking down. Lucifer invites Castiel to join him, reasoning that, as two of Heaven's castoffs, they are on the same side and Heaven will hunt Castiel if they manage to defeat Lucifer. Castiel refuses. Meg approaches her father, asking what to do with the Winchesters, and Lucifer tells her to leave them be, and gives her a reassuring touch.



Lucifer begins conducting the ritual to free Death. The Winchesters locate him, and while Sam distracts him, Dean shoots him through the skull with the Colt. He crumples to the ground, but after a few moments reawakens, and slowly gets to his feet. He punches Dean into a tree, and continues work on the ritual. When Sam asks him about the missing townspeople, Lucifer reveals that the women and children are in the mass grave he has been filling in, and that all the men are possessed. He tries to convince Sam that it was necessary, and insists that Sam should understand what he is doing, as someone who has always been out of place in his own family. Lucifer completes the ritual by commanding the demons around him to sacrifice themselves. Castiel, who has managed to escape, takes Sam and Dean away. Lucifer sees, but does not interfere. He turns, and greets Death.

In Hammer of the Gods, a group of Pagan gods of the supernatural realm gather to discuss the Apocalypse threatening to destroy the Earth while holding the Winchesters captive. Lucifer is tipped off about their meeting by Mercury.

Upon arrival, Lucifer expresses his disgust with the pagan gods' lack of loyalty and obliterates at least 8 of them in a bloody massacre until only Kali and the Winchesters remain. It is here that Gabriel intervenes on their behalf and sends them away before confronting his brother alone.

Gabriel tells Lucifer that he still loves him and that he is on nobody's side but humanity's. He tells Lucifer that he has no legitimate grievance and is merely jealous that humanity replaced him in the foremost of God's affections and that it is time for him to grow up. Gabriel wields his Archangel Blade against Lucifer (one of the few weapons that could truly kill him and his kind) which causes him to remain cautious during their exchange. Gabriel attempts to keep Lucifer distracted with a copy of himself while the real Gabriel tries to sneak up behind him and stab him. Lucifer sees through the charade, however, and turns his brother's own blade upon him, telling him that the trick he just tried to pull amounted to "amateur hocus pocus" and reminding him that Gabriel learned all of his tricks from him. After Gabriel died, Lucifer looks down upon his brother's corpse and lightly grieves for his brother's passing, openly weeping.

The Winchesters learn in a posthumous message from Gabriel, that they have no chance at all of killing Lucifer without his aid, though they can still trap him back in his cage in Hell if they can acquire the four rings of the Four Horsemen of the Apocalypse. Once they possess all of the rings, a plan is formed for Sam to consent to possession by Lucifer and then for him to jump into Lucifer's Cage with the Archangel in tow, a plan which Dean initially is resistant to but ultimately comes to accept the idea after realizing that Sam is now grown up and can make his own choices.

Defeat and Re-imprisonment
In Swan Song, Lucifer is tracked to Detroit, Michigan. Having ingested gallons of Demon Blood, Sam finally consents to Lucifer's possession even though the Devil reveals he already knows of their plan to try to force him back into his cage. Despite this, Sam goes forward with the plan in an agreed proposition with Lucifer: if Sam wins in their struggle for supremacy, he may jump in the hole and take Lucifer with him; but if Lucifer wins, he wins. Sam then says "Yes". The archangel quickly abandons his vessel to become one with Sam Winchester, knocking both out momentarily. This gives Dean the time he needs to open the cage before Sam seemingly recovers and walks toward the cage's mouth only to turn around and reveal that Lucifer is now in control of Sam's body. He closes the cage, takes the rings and vanishes.

Lucifer gathers several members of Azazel's demonic minions before him. Demon-possessed humans from Sam's past that secretly manipulated his entire life as they worked for Azazel just as Brady had done. The Devil decides to "take the gag off" and allow Sam to speak, telling him that he is his true family and that he should embrace their union. Hoping to appease Sam, Lucifer offers an olive branch to him by killing the demon-occupied people such as Sam's prom date, one of his former teachers, and all others present in revenge for their manipulation of Sam's life. Sam is only able to speak as his own reflection and finds himself outmatched by Lucifer.

The next day, Lucifer travels to Stull Cemetery outside Lawrence, Kansas, the place where he is fated to meet his older brother, Michael, who has since gained consent from Adam Milligan for their final confrontation. Lucifer tries to dissuade Michael from their battle and blames their current situation on God, suggesting that they may be able to just walk away. Although he strongly considers it, Michael, however, refuses to back down, stating that he must be a "good son" to their Father while chastising Lucifer for not taking any of the blame for what has happened. Michael calls him a monster. Despite telling Michael he'd like to see him try to kill him, Lucifer appears slightly hurt by his comment. Before either can make a move however, Dean Winchester arrives in the Impala and demands to speak to Sam. Michael is annoyed by Dean's audacity and demands that he leave, stating that he has no place on the battlefield now while Lucifer tells him that its whole new level of stupid, even for Dean.

Before he can do anything else however, Castiel hurls a molotov cocktail of burning Holy Oil at him, banishing Michael for several minutes and allowing Dean time to try to reach Sam. Lucifer, outraged that Castiel would strike Michael, snaps his fingers and obliterates Castiel. He then begins to beat Dean but is shot several times by Bobby Singer before he turns and telekinetically snaps Bobby's neck. Continuing his assault on Dean, the Archangel states that he will break every one of Dean's bones and make Sam feel it. Despite the brutal beating he takes, Dean does not resist and merely tells Sam that he will not leave him.

As Lucifer attacks Dean, he glances in the back of the Impala at an old army figure Sam had stuck in the ashtray as a child. The Archangel is then overwhelmed by all of Sam's happy memories of his life with Dean leading up to now, with his love for his brother finally breaking Lucifer's grip on Sam's body, allowing Sam to take control of the Devil at last. Sam tells Dean that everything is going to be all right and that he now has Lucifer under his control before tossing the Horsemen's rings to the ground and reciting the incantation to open Lucifer's Cage. As Sam goes to the mouth of the pit to throw himself in, Michael reappears and demands a fight with Lucifer, stating that it is his destiny to do so.

Sam disregards this however and, with one last look at Dean, outstretches his arms and begins to fall backwards into the mouth of the cage. Michael attempts to stop him but only ends up being pulled down into the pit alongside his brother as the portal shuts behind them in a thunderous flash of white light, leaving behind only the red-hot rings of the Horsemen. Dean, after being healed by Castiel, who also resurrects and heals Bobby after being restored himself by God, returns to the home of Lisa Braeden and sits down to dinner with her and Ben. The street light flickers outside her house and there, standing beneath the light and watching them, is Sam.

Season 6
Although Sam was brought back from the cage, albeit without his soul, Lucifer and Michael were still inside the cage. Castiel said that they were in the deepest corner of Hell and that they were probably torturing Sam's soul, having nothing else to do and blaming him for their imprisonment. Although they both were locked up, it is still possible to release the two of them. Raphael was attempting to break Michael and Lucifer free to continue God's plan. There was a Civil War in Heaven. Raphael's side wanted to continue the Apocalypse by setting Michael and Lucifer free, while Castiel's side wants to prevent it from happening again. At the end of season six, Raphael's side loses the civil war as Castiel has killed Raphael (and soon after his followers) after imbibing all the souls of Purgatory into his vessel (along with the Leviathans).

Season 7
Lucifer is still in the cage, but appears as a hallucination, due to Sam's memories of his time in Hell. This first happens with Sam in Meet The New Boss, where Lucifer tells Sam that the world he has been in for the last year is not real and Sam is still in the cage. A new form of torture which Lucifer prides himself on as being his best yet.

In Hello, Cruel World, Lucifer continues to taunt Sam on how this world isn't real. He points out that he made this world, because it was the most believable. Later Sam confronts Lucifer and asks him why doesn't he end this dream world to which Lucifer responds by saying that he will only end it when Sam can no longer take it anymore. Lucifer later changes into Dean and tricks Sam into leaving Bobby's house.

Once at the destination, he reveals himself to prove he can control Sam's "dream". Although Lucifer is proven to be a hallucination when Dean explains to Sam how to tell the difference between hallucinations and reality. Despite being proven a figment of Sam's imagination, Lucifer informs Sam that he's not going anywhere.

Lucifer is heard but not seen in The Girl Next Door and Defending Your Life.

In How To Win Friends And Influence Monsters, Sam and Bobby talk about how things are going. Bobby asks about Sam's mental state and Sam comments that he has it under control while touching his scar. Bobby doesn't believe this but lets it go.

In Death's Door, Sam is seen using his scar to keep Lucifer at bay while dealing with the state of Bobby Singer after being shot in the head by the Leviathan leader Dick Roman.



Lucifer returns in Repo Man, once again trying to tempt Sam into acknowledging his existence, thereby "letting him in" [to his head] again. He eventually succeeds after 'helping' Sam during the case. The episode ends with him once again gleefully tormenting Sam while Dean sleeps after a hard day's work.

Although not seen, he continued to torture Sam in Out With The Old causing him insomnia.



He again returns in The Born-Again Identity where his torture got too much and put Sam in a mental institute, Lucifer continued to torture him, linking it to when they were in the pit, making him hallucinate maggots in his food, throwing fire crackers at him to keep him up. Eventually, it got too much, and Sam snapped, his mind was so broken that it couldn't be healed (reaching the point where all people that Sam saw was Lucifer). However, in a last act to redeem himself for his previous actions in The Man Who Knew Too Much and Meet The New Boss, Castiel transferred the hallucinations from Sam's mind to his own mind. Lucifer, uncaring about the change, just calmly said, "Hello brother" and presumably went on to torture Castiel as he did to Sam.

Castiel later reveals in Reading Is Fundamental that Lucifer's appearance to him was more of an "aftertaste" of Sam's experiences, which quickly wore off, eventually replaced by visions of everything Castiel had done wrong.

Season 8
In Goodbye Stranger, while Lucifer himself doesn't appear, it is revealed that he has a series of crypts that are buried around the world containing important things, including the angel tablet. Only those closest to him know their locations, including Azazel, so when Crowley went after the tablet, he tortured Meg for the locations as she knew from her time with Azazel. Eventually Dean and Castiel found the tablet in an angel-proofed box in one of his crypts.

Season 9
In Holy Terror, Lucifer's corruption of the Garden is revealed when Metatron confront's Gadreel about the matter and uses Gadreel's failure and his desire to atone for his mistakes, to get his assistance with his own plans.

In Road Trip, Dean, Castiel and Crowley captured Gadreel, who has possessed Sam, and learn that he was the one who allowed Lucifer into the Garden which greatly angers Castiel.

In First Born, Dean learns of Lucifer's involvement in Cain's killing of Abel from Cain himself as Lucifer was talking to Abel, that Cain allowed Lucifer to corrupt him instead of Abel and turned him into a demon.

Given the revealed events of Lucifer's involvement with Adam, Eve, Cain and Abel, it would seem that his previous claims of innocence were in fact deceptions.

Personality
"You know I never understood you pagans. You're such petty little things. Always fighting. Always happy to sell out your own kind. No wonder you forfeited this planet to us. You are worse than humans. You're worse than demons and yet you claim to be Gods...and they call me prideful."

- Lucifer to Mercury.

Lucifer was once the most beautiful and beloved angel in all of existence. God loved Lucifer the most of all his angels. Because of his elevated status among the other angels, Lucifer was very proud. When humanity was created, he was unwilling to accept that he was no longer God's favorite. When God commanded all those of Heaven to love his new creation more than himself, Lucifer refused. Lucifer pleaded: "Father, I can't. These human beings are flawed. Murderous!" Lucifer continued his disobedience, asking Michael to stand by his side in his rebellion against God's orders. Michael refused Lucifer's request, and under God's command, Michael cast Lucifer into Hell.

Naturally, being cast out of Heaven enraged Lucifer, and he struck back by tempting and twisting the soul of a human woman, Lilith. After completely stripping her of her humanity, her soul was transformed into the very first demon. Because of this unforgivable blasphemy against God, Lucifer was further punished by being placed into an additional solitary imprisonment within Hell. He remained there in isolation for a millenium. Lucifer's long term goal was to eventually be freed from the Cage, eradicate humanity, and restore Earth to its original "untainted" glory. It is suggested that Lucifer only uses demons as servants and would eradicate all of them as well, because, despite them being his creations, he considers demons to be even less worthy than humans. Proof of this is shown when he casually kills dozens of them. However, he holds his greatest contempt for Pagan Gods, believing them to be petty, disloyal and the lowest of all beings because they claim to be gods.

Lucifer claims that he never lies or even tricks, because he does not have to, as he has said, "I will never lie to you. I will never trick you." He promised both his vessels, Nick and Sam, that he would be honest with them. He also said that he sympathizes with his vessels, both of whom are victims like himself. He went to some lengths to get Sam's acceptance, sparing Dean's life on several occasions, and allowing Sam revenge against some of the demons that controlled his life. Despite this, Lucifer has been proven to mislead on occasion, suggesting that this was more of a ploy to gain trust, rather than an actual commitment, and he would bend this rule when it's to his advantage. Further more, Lucifer tries to gain sympathy from his opponents such as Dean by claiming that he is truly a victim and was justified in his actions.

Lucifer shows concern for his fellow angels, though it is the archangels he loves most. He captured Castiel and admired the angel's loyalty in refusing to reveal the presence of his friends. He invited Castiel to join him, and when Castiel refused, Lucifer respected his decision and offered him a chance to change his mind. Lucifer was remorseful when forced to kill Gabriel and disappointed when Michael berated him. When preparing to fight his older sibling in their pre-destined battle, Lucifer pleaded with Michael to "walk off the chessboard," but Michael remained determined to fulfill his destiny and serve God. Even so, when Castiel struck Michael with holy fire, Lucifer was outraged by the attack on his brother and obliterated Castiel.

Gabriel criticized Lucifer, describing his actions as "one great big temper tantrum." Death and Crowley both made similar observations, as they have both called him a bratty and petulant child with daddy issues. Nonetheless, Lucifer sees himself as a tragic figure who was punished for being right. He refuses to accept any blame for his actions and suggests that God intentionally made Lucifer the way he is, asserting that "God wanted the Devil."

Lucifer is also highly cruel and barbaric to those who get in his way, and despite his claims of being the victim, he has no qualms about killing anyone who angers him, even if he has no true reason for killing them. For example, he barbarically massacred all the pagan gods (except for Kali, who was rescued and escaped), simply because they plotted against him, despite the fact that they posed no real threat to him and takes great pleasure in beating Dean for being "such a pain in (his) ass." He also slaughtered an entire town by sacrificing the women and children and then having his demons possess the men before killing them just to raise a horseman.

Powers & Abilities
As an elder archangel, Lucifer is one of the most powerful beings to exist, possessing nigh-omnipotent supernatural power. Lucifer is described as being an angel of immense power and strength. Because archangels are independent when cut off from Heaven, Lucifer maintains all his powers, even while in Hell. The immensity of his power was further shown by how an improper human vessel, Nick, decayed greatly as a result of containing him and had to consume gallons of demon blood to maintain his form. Only few beings are more powerful than him, one of which is Michael, though he showed no fear when facing his older brother.
 * Nigh-Omnipotence - Being the second oldest archangel, Lucifer is incredibly powerful. As only few beings can defeat him with certainty, Lucifer has incalculable supernatural power. Zachariah explains that Lucifer is powerful in ways that defy description and that his very presence on earth would cause fiery skies and summon the Four Horsemen of the Apocalypse. He can even slay ancient pagan deities with ease, despite using an imperfect and decaying vessel, and he is shown to be more powerful than even the oldest and mightiest of pagan deities. The immensity of his power can be seen when he possesses an imperfect vessel; it will begin to slowly decay and eventually spontaneously combust due to barely being able to contain Lucifer's immense power and presence, something that the human body was not built to process. Only a vessel that was built specifically to contain Lucifer, such as a descendant of Cain and Abel, can successfully and safely host him and access his full power. With Sam as his vessel, he can use the full extent of his powers. Unlike most characters, the extent of his powers is not limited by his presence, as such giving them a near infinite range. His power is so vast and so feared that Castiel, even while empowered by millions of souls, showed he didn't want to risk setting Lucifer free.
 * Immortality - As an angel, Lucifer has an infinitely long lifespan. Time does not degrade his vessel, like with all celestial beings. He is among the first angels and is therefore older than the Earth itself, making him well over 4.5 billion years old. The excessive passing of time does not degrade his vessel, like with all celestial beings. His vessel is unaffected by diseases and toxins. He does not tire, and does not require food, water, oxygen, or sleep to sustain his vessel. On one occasion, Castiel clearly says about killing Lucifer, "It's foolish, it can't be done", and later calls the task "insane". However, an archangel blade can kill him, as can God and Death. Higher Leviathan may prove a challenge to him, and Eve may have been able to weaken him with her presence.
 * Angelic Possession - Like all angels Lucifer is required to use a vessel on Earth, as Zachariah emphasizes. And he needs the vessel's permission, as with all angels. Because of the immensity of his power, he must use a vessel descended from Cain or Abel, or it will begin to decay and eventually spontaneously combust.
 * Invulnerability - Lucifer's vessel is impervious to damage and injury, except when harmed by an archangel blade, God, Death, a Leviathan, Eve, supernatural weapons of significant power, or his archangel brethren. Kali, the most powerful of the deities at the gathering of the pagan deities, tried to harm him with a pyrokinetic attack, but it had no effect and Lucifer simply smiled at her attempt at harming him, showing him to be unaffected by extreme temperatures. The Colt caused him initial pain, but he soon recovered, though it should be noted that his temporary vessel was decaying at the time.
 * Immunity - Lucifer is one of only five things in creation that the Colt cannot kill.
 * Cosmic Awareness - Lucifer has immense awareness of everything, as Sam has said, "I'm sure he knows a buttload we don't". He possesses absolute wisdom and the potential to transcend all earthly things. He knows spells capable of binding the Horsemen to him, but he, according to Chuck, didn't know about the Impala.
 * Superhuman Strength - As an archangel, Lucifer endows his vessel with immense superhuman strength, sufficient enough to having slaughtered ancient pagan deities, even the mightiest of pagan gods, with his bare hands with minor effort. As Gabriel predicted, Lucifer "turned them into finger paint." Lucifer went on a rampage during which he brutally ripped the other gods to shreds, beating them to death and tearing off their limbs through sheer force. He was able to knock down Kali with one punch and punched through Baldur's chest. This makes him among the strongest beings in all of existence. As the second oldest archangel, he's significantly stronger than the vast majority of any other supernatural beings: such as angels as well as all demons, spirits, humans, and earthly monsters, including the alphas. He was also able to casually overpower his younger brother Gabriel, an archangel like him. Humans are powerless against him in terms of physical might; he once effortlessly threw Dean into the Impala with great force and literally beat him to a bloody pulp, nearly killing him. Although his archangel brethren are his equals, only Michael is his certain equal and possible superior in strength.
 * Super Stamina - His vessel is unaffected by diseases and toxins. He does not tire, and does not require food, water, oxygen, or sleep to sustain his vessel.
 * Regeneration - If Lucifer's vessel receives any physical damage, the wound will completely heal instantaneously. When shot with the Colt, for example, the bullet hole healed in under a minute. Interestingly, the ability does not reverse the decay caused to Nick by Lucifer's power. Lucifer is unaffected by natural diseases and illnesses as well as to supernatural infections such as the croatoan virus.
 * Shapeshifting - Lucifer can change his form regardless of being inside a vessel or otherwise. Lucifer can change his shape into any person he wanted, similar to Gabriel's ability; it is possible that Lucifer once took the form of a Reaper to lure Castiel away.
 * Teleportation - Lucifer can travel anywhere instantly without occupying the space in between. However, when imprisoned in his cage, he cannot leave unless it is opened by an outside force.
 * Power Negation - Lucifer could prevent lesser supernatural creatures from using their powers, as Baldur and Kali where unable to teleport either themselves or the Winchesters when he arrived at the motel where they were hiding.
 * Telepathy - Lucifer had complete access to Sam's memories and thoughts while he possessed him.
 * Empathy - Lucifer could read the emotions of his vessel, and presumably humans who were not his vessel.
 * SN519.jpgAdvanced Telekinesis - Lucifer can impart kinetic energy on matter with his mind. He is extremely proficient, being able to rip pagan deities apart with this power.
 * Dream Walking - Lucifer has the ability to enter a person's dreams. Even without a human vessel, Lucifer was able to speak with Nick in his dreams while taking on the appearance of his deceased wife. He demonstrated this again when he spoke to Sam in his dreams while taking on the appearance of Jessica Moore.
 * Thermokinesis - Lucifer can alter temperatures to a drastic degree. His presence alone in Detroit caused incredible drops in temperature and he froze a pane of glass by merely breathing on it.
 * Supernatural Perception - Lucifer can perceive the true form of beings invisible to the human eye. Lucifer was able to see the true form of Death when he raised the Horseman out of his prison.
 * Weather Manipulation - When Lucifer was released, he altered the weather by creating severe winds and causing hurricanes and tornadoes across the world. He made the entire city of Detroit's temperature drop simply through his presence.
 * Biokinesis - Lucifer killed Castiel by speeding up his molecules to the point where it caused him to explode simply by snapping his fingers.
 * Advanced Reality Warping - Although never displayed in person, Lucifer reminded Gabriel that he taught him everything he knew about using this power, when the latter tried to use it to kill him. Upon his escape the Koreans made their first successful nuclear test.
 * Spell Casting - Lucifer was able to bind the Horsemen to his presence with a spell, controlling their actions to a moderate degree. He also performed a ritual sacrifice of demons to release Death from his coffin. He also knew how to ward angels from the Angel Tablet.
 * Resurrection - Lucifer can easily revive dead people. Raphael was under the impression that he is powerful enough to bring back deceased angels.
 * Terrakinesis - Lucifer could generate earthquakes through his mere presence on the earth; he was able to cause them at a colossal range, creating several across the whole world while he was in America.
 * Precognition - Lucifer could see and accurately predict the future, but he could not see the whole picture; he knew he would possess Sam in Detroit and told him the first time he met him.
 * Torturing - Lucifer is skilled in torture, both physical and spiritual. He tortured Lilith's spirit to the point where he turned her into the original demon. He also tortured Sam to the point where the mental damage would have killed him, had Castiel not absorbed the damage.
 * White Light -  He once captured Castiel by disabling him with a burst of white light. It is possible the Lucifer can destroy vast areas with this ability
 * Psychic Projection - Despite being trapped in the cage, he could still communicate to beings on Earth, as he did with Azazel, though Azazel had to sacrifice several nuns for this to be achieved.

Weaknesses
He is incredibly powerful in his own right, even being the second oldest archangel in existence, Lucifer has a few weaknesses in comparison to his archangel brethren.


 * Archangels - While all other angel types can't physically hurt Lucifer with their own strength, archangels can physically hurt each other. But he is considerably stronger than Gabriel and Raphael. Lucifer potentially rivals Michael's power, but Michael is ultimately stronger.
 * Archangel blades - Archangel blades can harm and kill Lucifer.
 * Lucifer's Cage - This cell can hold any angel, therefore including Lucifer, without any internal means of escape.
 * Enochian Sigils - Lucifer cannot locate someone if they are warded by enochian sigils.
 * Death - As literally the bringer of Death, he can kill any being, including Lucifer.
 * God - As the creator of Lucifer, and the most powerful being in existence, God can kill Lucifer.
 * Death - As literally the bringer of Death, he can kill any being, including Lucifer.
 * God - As the creator of Lucifer, and the most powerful being in existence, God can kill Lucifer.

Quotes

 * "You people misunderstand me. You call me "Satan" and "Devil" but...do you know my crime? I loved God too much. And for that he betrayed me -- punished me. Just as he's punished you. After all, how could God stand ideally by while that man broke into your home and butchered your family in their beds? There are only two rational answers, Nick -- either, he's sadistic...or he simply doesn't care."
 * "Sam...my heart breaks for you. The weight on your shoulders: what you've done, what you still have to do, it is more than anyone could bear. If there was some other way...but there isn't. I will never lie to you, I will never trick you but you will say yes to me."
 * "I was a son. A brother, like you. A younger brother. And I had an older brother who I loved. Idolized, in fact. And one day, I went to him and I begged him to stand with me, and Michael...Michael turned on me. Called me a freak. A monster. And then he beat me down. All because I was different. Because I had a mind of my own. Tell me something Sam, any of this sound familiar?"
 * "No one gives us the right...we take it."
 * "Sorry if it's a bit chilly. Most people think I burn hot. It's actually quite the opposite."
 * "A wrestling match inside your noggin? I like the idea. Just you and me, one round? No tricks. You win, you jump in the hole. I win...well then I win. What do you say, Sam? A fiddle of gold against your souls says I'm better than you."
 * "I've been waiting for you for a long long time. Come on, Sam. You have to admit, you can feel it, right? The exhilaration. And you know why that is? Because we are two halves made whole. M.F.E.O. Literally."
 * "You can't lie to me. I see it all. How hot you always felt. How out of place in that family of yours. And why shouldn't you have? They were foster care, at best! I'm your real family."
 * "All those times you ran away, you weren't running from them: you were running towards me."
 * "Think about it: Dad made everything, which means he made me who I am. God wanted the Devil!"

Trivia

 * Being the boss of Azazel and Lilith, Lucifer is the overall bigger bad of Supernatural starting in season 1 to the end of season 4. He takes the stage as the main antagonist in season 5 and comes back as a secondary antagonist in season 7.
 * Series creator Eric Kripke has jokingly compared him to a "raging psychotic" version of environmentalist Ed Begley, Jr., with "unlimited power". * A homage to John Milton's Paradise Lost, Lucifer will be portrayed as "gentle, almost sympathetic." Kripke further characterized him as a "Devil who has doubt" and "a lot of affection for God and the angels," and who "speaks really tenderly and gently and...doesn't lie."
 * Kripke reasoned, "He was essentially betrayed, so in some ways he can be viewed sympathetically ... if we can make the angels dicks, Lucifer can be sympathetic."
 * The way Lucifer killed Baldur is similar to the way, Albert Wesker killed Ozwell E. Spencer in the video game series Resident Evil, in both method and words delivered upon killing their respective victims.
 * Of all the archangels, Lucifer has appeared the most in the series.
 * So far in the series, Lucifer has used two vessels, Nick and Sam Winchester.
 * Lucifer is the only archangel whose name doesn't end with "el" but end with "er." This is because Lucifer is the Latin calque of the Hebrew Heylel.
 * Before Season 5 it was believed that God was the one who locked him in his cage but it was then revealed in Season 5 that it was actually Michael who cast Lucifer into Hell on God's orders.
 * The Devil is known by many names throughout different faiths: Lucifer (Latin for " 'The Morning Star' or 'light bringer'"), The Devil, The Serpent, and Satan (Hebrew for "Adversary").
 * According to Mark Pellegrino in the Season 7 Companion Guide, Lucifer was probably more than just a hallucination and that he was possibly a psychic projection of Lucifer still stuck in The Cage.
 * Lucifer was named one of TV Guide's "Top 60 Villains of All Time"..
 * As with Gadreel, Lucifer is the most significant antagonist of the series. He is the one who brought about the chaos upon the universe, creation of demon kind, God leaving (alongside Gadreel's failure) and the Apocalypse. While Gadreel is the indirect catalyst for these events, Lucifer directly carried out these actions.
