Lucifer

Lucifer, also known as The Devil, Light Bringer, The Morning Star, and Satan, is the second of the four Archangels created by God and was his favorite son. He is also a fallen archangel, and the first fallen angel. He is a recurring character, was the main antagonist of Season 5 and Season 12, and the secondary antagonist of Season 7 and Season 11. He is the original ruler of Hell and the creator of demons, seen by them as a father figure and their god. As the second-born Archangel, he is the younger brother of Michael, and older brother of Raphael and Gabriel.

According to Gabriel, Lucifer is, or at least was, God's favorite and most beloved celestial, but when God asked for all angels to bow down to humanity, Lucifer refused both out of jealousy and wounded pride over being commanded to bow to what he saw as a broken, flawed, and murderous species and no longer feeling he was God's favorite creation. This was caused by the Mark of Cain corrupting him and boosting his dislike towards humanity. He waged a war against God but was eventually cast out of Heaven by God, and banished to Hell by Michael. All of Azazel's actions were motivated with the goal of eventually releasing Lucifer from his cage in Hell.

Like all other angels, Lucifer must have the permission of a strong enough human 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, every pagan, and also every demon and species of monster, most of whom deify him, thus being among the most powerful entities the Winchesters have ever encountered. But his power causes regular vessels to decay and required to drink vast amounts of demon blood or possess either his true vessel (Sam Winchester) or an alternate more stable vessel (Castiel).

Eventually, 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 Sam Winchester, 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 back in Lucifer's Cage.

After the release of the Darkness about five years later, the cage was damaged and Lucifer (whilst he still couldn't leave it) began reaching out to Sam to get him to return to Hell and release Lucifer so he could return to the world, working with Rowena to achieve this. Though Sam refused, Castiel said "yes" and Lucifer returned to the world in Castiel's body.

After reconciling with God, Lucifer joined him, Sam, and Dean in an attack to defeat Amara. However, Amara, not wanting to be re-imprisoned, overpowered God and in her rage, she pulled Lucifer from Castiel's body when he went to attack her and help his father. It is unknown where he was banished to, but he survived and was able to take possession of Vince Vincente, an aging musician. After the death of Vince, Lucifer began seeking out vessels with power and influence, culminating in President Jefferson Rooney. Lucifer was eventually exorcised from Rooney and returned to his Cage, but not before he conceived a Nephilim with Kelly Kline. It was later revealed that Crowley perverted the spell so that Lucifer became his prisoner in the body of Nick once more. Later however, Lucifer (with the help of a demon) is able to turn the tables on Crowley and seemingly kills him. He then reclaims his position as Ruler of Hell and sets off to find his unborn son. After a battle with the Winchesters and Crowley, Lucifer killed Castiel and was trapped in an alternate reality by Mary Winchester. However, she remains trapped with him.

Origins
"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 humans 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 six billion of you have done to this thing. And how many of you blame me for it?"

- Lucifer to Dean, about why he was cast down from Heaven

Eons ago, Lucifer was the second archangel that God created and was raised by his older brother Michael. Lucifer was at one time the favorite of God's angels, and his name translates to "Light Bringer." It was stated that he once had a strong relationship with God and was fiercely loyal and devoted to him. Before life and even the Earth existed, Lucifer fought a war with God and the other archangels against God's older sister, the Darkness. When they won by sealing The Darkness away, God created the Mark of Cain as the lock on the Darkness' prison and gave it to Lucifer, his most trusted lieutenant to protect. However, the Mark's power corrupted Lucifer and caused him to foster jealousy.

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, stating that he "merely questioned his priorities". Being full of pride and jealous of God's love, Lucifer refused to bow to a creature that he considered lesser than himself and God, whom Lucifer loved too much to being able to devote himself for the, as he says, imperfect humans. 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, at his father's orders, 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 prophets 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. It's unknown how Lucifer convinced him but it is implied that Gadreel was unaware of Lucifer's true intentions. Once in the Garden, Lucifer twisted the minds of the humans, causing them to partake of the Forbidden Fruit (the Quince). Some time before or after this, Lucifer corrupted Lilith into a demon. Because of his actions, God created Hell and had Michael cast Lucifer into it. Being now corrupt, this got humanity expelled from the Garden. Lucifer at some point managed to 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 passed the Mark of Cain onto him. The Mark eventually changed Cain into a powerful demon who personally created and trained the Knights of Hell, an elite order of warrior demons hand-picked by Lucifer himself out of the very first demons. According to Crowley, Lucifer also created the Princes of Hell around the same time, powerful demons created after Lilith that were to be the generals of Hell's armies. These included Azazel, Ramiel, Dagon, and Asmodeus.

Lucifer's prison, a chained cage in a dark void with powerful lightning bolts around it, was designed so that he could never leave or escape it on his own, and it was then further locked with over 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 seals will suffice.

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.

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, save for Lilith, Cain, the Knights of Hell, and the Princes of Hell, had truly seen Lucifer, as he was locked away in a special part of Hell that was it's own metaphysical prison, unreachable to almost all beings, locked by the 600 seals, with only 66 required to remain intact to keep Lucifer sealed within; this left the vast majority of demons without hope that they would ever find Lucifer and return him to power, save for the Prince of Hell Azazel, hells ruler at the time, who eventually escaped to Earth in search of a way to free Lucifer from Hell.

In 1972, years after years of searching, 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, 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 and positioned one atop the altar in a ritual sacrifice designed to allow for a brief conversation with Lucifer.



After 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 the 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 had 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, a plan that took decades to accomplish, as well as Azazel and Lilith's deaths before their plan came to pass.

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 other seals 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.

Dean is rescued from Hell after four months and soon after, 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. However, Zachariah implied that because the archangels, or "senior management", wanted the seals to be broken, they allowed the seals to be broken under the guise of trying to stop them to avoid rebellion in Heaven.

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 rise of Lucifer
When Dean realized the truth about the angels' intentions, he escaped confinement from the green room, though he was too late to warn Sam that killing Lilith would, in fact, ensure Lucifer's release rather than prevent it, as Ruby had informed him. Lilith mocked Sam to override the pleas from his brother, and Sam killed Lilith with his powers. As Lilith's blood began forming a portal to Lucifer's Cage, Ruby revealed that she had been working with Lilith all along and that Lucifer himself had foretold that only Sam could kill Lilith. Dean killed Ruby with her own demon-killing knife with Sam's help. Together, the Winchester brothers watched in horror as the mouth of the Cage 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, they were teleported 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 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. "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 idly 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."

- Lucifer

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. "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."

- Lucifer



Some days after that, Lucifer appeared to Sam in the form of his deceased girlfriend Jessica Moore, telling him that no matter how many times he ran away he will always be part of the supernatural, people who get close to him will get killed, and 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 was his true vessel. Lucifer states that he will never lie or trick Sam into saying Yes, but he will do so willingly, before disappearing.

Shortly after, 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 discovers a world in which Lucifer won the war due to Sam saying "Yes". This Lucifer manages to kill the Dean of that universe but he chooses to spare Past!Dean. He talks about the inevitability of him losing the war before Dean is taken back to his current year by Zachariah.

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. "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?"

- Lucifer

After receiving the Colt, Sam, Dean, Castiel, Ellen and Jo join forces in order to kill the Devil. It is shown that Nick's body is beginning to 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 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 the demon kind once humanity is gone.

Lucifer manages to trap Castiel inside a ring of Holy Oil, while 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. 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 he reawakens, and slowly gets to his feet, expressing his pain at being shot by the Colt. He punches Dean into a tree, and continues to 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.

"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

Due to the ongoing apocalypse, a group of Pagan gods 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 eight 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 Gabriel that he learned all of his tricks from him. After Gabriel dies, 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
During the final phases of the Apocalypse, 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. Lucifer tells him that his actions amount to a whole new level of stupid, even for Dean.

Before Michael can attempt to remove Dean from the scene, Castiel appears and hurls a molotov cocktail of holy oil at the elder archangel, banishing him. Lucifer, outraged over Castiel's actions, snaps his fingers and obliterates the angel. 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 alright and that he now has Lucifer under 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.

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 planned to break Michael and Lucifer free to continue God's plan. This led to a civil war in Heaven. Raphael's side wanted to continue the Apocalypse by setting Michael and Lucifer free, while Castiel's side wanted to prevent it from happening again. At the end of season six, Raphael's side loses the civil war as Castiel kills 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 shortly after the Leviathans had been released, 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.

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. Sam later confronts Lucifer and asks him why he doesn't 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 as 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 became so bad Sam was put in a mental institution. 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 confronts 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. In order to save his brother, Cain made a deal with Lucifer to take Abel's place in Hell in exchange for Abel getting into Heaven. Lucifer agreed if Cain killed his brother and gave him the Mark of Cain afterwards.

Season 10
In Brother's Keeper, after Dean summons Death to kill him due to the Mark's worsening influence on him, Death explains Lucifer's role in the war against the Darkness and how it was the Mark's power that corrupted Lucifer into being jealous of humanity. He tells Dean that if he wants to be rid of the Mark without unleashing the Darkness, he must pass it on as Lucifer did to Cain.

Season 11
In Out of the Darkness, Into the Fire, a demon tells Crowley that after the Darkness was released, there was an uproar from Lucifer's Cage, believing that Michael or Lucifer was trying to warn them.

In Baby, Sam believes he's having another vision, when Lucifer appears to him in the guise of a young John Winchester. "John" tells him, he's only here to deliver a message. That the Darkness is coming and only the boys could stop it. Sam insisted that there should be a way to stop the Darkness, but John only answered, "God helps those who help themselves." Sam asked "John" one last question before he woke up, "Who are you?"

In Our Little World, after Sam and Dean question Castiel about Metatron, Sam experiences a vision of Lucifer's Cage, which is seen for the first time from the outside. Two hands are seen to be grasping the wall of the cage, though it remains unclear who the hands belong to.

In O Brother, Where Art Thou?, Sam has a vision of Lucifer touching him and feeling a sense of peace, causing Sam to believe that God wants him to go to Lucifer and get his help. With the help of Crowley and Rowena, Sam is able to summon Lucifer himself into a small cage in the depths of Hell where he is rendered powerless by warding from the Book of the Damned and holy fire. Lucifer manifests in the form of Nick and Sam explains the situation and his visions from God. Lucifer tells Sam that the visions mean that God needs his help to defeat the Darkness and he needs Sam to say "yes" again so he can get out and help. Lucifer insists that the visions are the Word of God and Sam needs to do what they say. Sam finally decides not to say yes, but the warding suddenly fails and Lucifer teleports Sam into the cage with him. Sam refuses to be afraid due to his visions, but Lucifer explains the truth: they didn't come from God, they came from Lucifer himself to draw Sam to him. The release of the Darkness damaged the Cage and it allowed Lucifer to reach out to Sam's mind and implant the visions. Lucifer tells Sam he's now trapped with him and taunts a terrified Sam by saying he was the hunter's only hope of escaping.

In The Devil in the Details, it is revealed Lucifer entered Rowena's dreams seeking her help with a plan to bring Sam into the cage, promising to make her his queen in exchange.

In the present, Lucifer shows Sam a memory of Sam as a teenager when he was a hero and then when he was with Amelia Richardson, saying that Sam had gone soft after Dean went to Purgatory. Lucifer tells Sam that the Sam who had defeated Lucifer and returned him to the Cage would not have allowed Dean to talk him out of boarding up Hell. Lucifer attempts to get Sam to say "yes" again as Lucifer insists he's the only one who can beat the Darkness with Gabriel and Raphael dead and Michael having gone insane. Sam refuses, knowing that whoever wins between Lucifer and Amara, the world loses. Lucifer starts to beat on Sam when Castiel and Dean arrive to stop them. Lucifer teleports the two into the cage and Sam, Dean and Castiel fight Lucifer to buy Rowena time to send him back to the Cage.

As Rowena is about to, Castiel asks if Lucifer can really beat the Darkness and when he confirms he can, Castiel says "yes". Lucifer possesses Castiel which anchors him and keeps him from returning to the Cage. Lucifer poses as Castiel until Sam and Dean are gone and then returns to Hell where he reveals himself to Crowley and Rowena. After making sure Rowena is the only one who can open the Cage, Lucifer snaps her neck and then takes a seat across from Crowley.

During Into the Mystic, Lucifer returns to the surface and arrives at a park. He feeds the ducks in the pond before sitting down and admiring the humans around him. An angel however, spots him and Lucifer decides to take a nature walk. Although he tries to talk the angel into trusting he is here to stop the Darkness, the angel refuses and makes a move to kill him. Lucifer snaps his fingers, instantly killing the angel.

Lucifer goes to the Bunker in search for a spell that can summon the Darkness. Dean finds him but still believes he is Castiel, and Lucifer plays along. Dean confesses he is drawn to the Darkness in ways he cannot resist and that it scares him. Lucifer reassures him that it's alright.

In The Vessel, Lucifer has regained control over Hell and now has Crowley as his "dog". After having a bunch of weapons brought to him from his crypts, Lucifer admits that defeating the Darkness was more of a "team effort" than he let on and he can't defeat her alone. As Lucifer taunts Crowley, he gets a call from the Winchesters and is shocked to learn of their discovery of a Hand of God. Lucifer agrees to bring Dean back in time to the USS Bluefin to retrieve the Hand of God, but is kept outside the ship by warding.

Lucifer returns to the bunker soaking wet and works with Sam to find a spell to remove the warding. Sam locates such a spell, but it requires the power of an archangel. Lucifer begins preparing the spell while Sam offers to allow "Castiel" to use his soul to increase "his" power so it will work. Lucifer reveals himself to Sam, seeing that he no longer has a use for him and begins to draw power from Sam's soul while planning to use it to destroy him and make it look like an accident. Before he can kill Sam, Castiel manages to regain control but informs Sam that he can't eject Lucifer as it's taking all of his strength to keep Lucifer from killing Sam. Castiel also informs Sam that they need Lucifer as Castiel can no longer time travel.

As Delphine Seydoux unleashes the power of the Hand of God, the warding is destroyed and Lucifer returns Dean to the present as the Bluefin is obliterated. Sam reveals Lucifer's true identity to Dean and Lucifer throws Dean across the bunker. Lucifer attempts to use the Hand of God, but finds its power depleted. As Lucifer stalks towards Dean, Sam manages to banish him from the bunker.

A week later, Lucifer is ordering the demons to locate a Hand of God. He orders Simmons to pretend to side with Crowley so the former King would lead them somewhere useful, which turns out to be a secret lockup. Lucifer follows them to the location. Once there, he reveals to Crowley that his plan was to rid Crowley of his last inch of defiance. He promises to do bad things to Crowley while he moves to take the Rod of Aaron, a Hand of God.

However, Crowley tricked them into thinking the rod was inside a case but he had, in reality, stashed it nearby and proceeds to strike Lucifer with it, sending him tumbling a few feet away. Crowley absorbs the rod's power and prepares to blast Lucifer with it, but Simmons shields Lucifer and dies. Lucifer is knocked back by the sheer force of the blast, but with Crowley having depleted the rod, Lucifer regains the upper hand and punches Crowley, sending him over a pile of books. When Lucifer leans over, the demon is gone.

After sending his demons on a worldwide search for Crowley, Lucifer enters Heaven, where he meets and kills Jofiel. He gathers the rest of the angels to talk them into trusting his aide in the coming battle with the Darkness, citing again that he was right about how bad humans were. The angels eventually agree to listen to his command, but an attack from the Darkness disturbs everyone in Heaven.

Later on, Dean summons Lucifer to a church with the promise of giving him the Horn of Joshua. Sam summons a ring of holy fire around the archangel once he arrives, and use an angel suppressing sigil to get Castiel to talk to them. Lucifer proves too powerful for the sigils to work. Crowley, who has now sided with the Winchesters, decides to enter Castiel's body to speak with the angel himself.

Unfortunately, Castiel has lost most interest in the war, allowing Lucifer (in the form of Nick) to approach Crowley and attack him. Just as Lucifer is about to suffocate Crowley up against a wall, Sam and Dean respond to a distress call and exorcise Crowley, thus saving his life. Lucifer takes back control of the vessel and approaches the brothers, since the wardings have worn off.

He is interrupted in his torturing of Sam and Dean when Amara bursts in, looking for Rowena, who had been assisting the brothers. Having taken the Horn of Joshua, Lucifer attacks Amara with it. The weapon, combined with Lucifer's powers proves too weak to even harm The Darkness. Amara brings Lucifer towards her and takes him elsewhere, for a "nice long chat".

Amara tells a bloodied Lucifer that she is going to use "God's favorite, his first son" as bait, and proceeds to torture the archangel, brushing aside his suggestion that they could work together against God. Lucifer begins screaming in agony.

In All in the Family, Amara continues to torture Lucifer who is badly beaten and burned from it. Lucifer continues to refuse to call out to God to save him and Amara sends a message to Dean of Lucifer's state in hopes of reaching God.

While Dean distracts Amara, Sam, Metatron and the Prophet Donatello Redfield come to Lucifer's rescue. Lucifer taunts the group, but agrees to put aside his differences with God and the Winchesters to help them fight Amara. Metatron frees Lucifer, but Lucifer is unable to teleport the group out in his injured and weakened state. Donatello senses Amara approaching so he and Sam flee in the Impala with Lucifer while Metatron stays behind and sacrifices himself to allow them to get away.

As the group flees, Amara appears in the middle of the road and prepares to kill them. However, before she can succeed, God teleports the Impala and its passengers to the Men of Letters bunker, saving them. There, Lucifer is reunited with God for the first time in millions of years and the two comment on how much the other has changed. To Lucifer's surprise, God heals his injuries from Amara's torture, implying that he has forgiven him.

While Sam and Dean are out buying groceries, Lucifer and God talk. Lucifer asks where God was and asks if he suspects healing him would earn him forgiveness. He sarcastically remarks that God returned when the apes sent a distress signal, prompting Dean - who had returned by then - to remind that "these apes saved your ass".

Annoyed, Lucifer attempted to smite the brothers with a snap of his fingers, but found he couldn't. God told the Winchesters he was preventing Lucifer from harming them, which annoyed Lucifer further. Sam tried to remind the pair that they had a common foe to deal with, but Lucifer was still unhappy and challenged God to "say it". A lack of response prompt Lucifer to storm off and lock himself in Sam's room, saying he would only leave if God had something to say.

The brothers managed to get God and Lucifer to sit and talk, during which Lucifer complained that God always acted like he had a reason for everything, and that locking him up for something the Mark caused him to do was his fault, despite Lucifer being God's son. After banishing Sam and Dean, God confessed that he did love Lucifer the most, and suffered from disappointment, and was truly sorry for his actions, to which Lucifer finally forgave. God and Lucifer reconciled their differences and the Archangel's allegiance was with his Father again.

Afterwards, Lucifer, God, Sam and Dean gathered in the war room to discuss their plan. God wanted to trap Amara again and needed substitutes for the archangels. Dean and Sam decided to recruit the demons and witches, while Lucifer went back to Heaven and recruited the angels, but found them hostile. He then switched places with Castiel and allowed his younger brother to talk to them.

The plan set, Lucifer gathered with the team at the location where they plan to trap Amara. Lucifer meets Crowley and Rowena here, and they have a bit of an argument over which species is better. When Amara does arrive, Lucifer waits inside for Amara to enter in her damage state. Amara sees God for the first time and walks up to him. Lucifer takes this opportunity to impale her with his spear, and Amara to falls to her knees.

Lucifer attempts to impale her again, but God stops him. As God prepares to seal Amara away again, a furious and enraged Amara retaliates and levitates her brother while choking him. Lucifer, with his spear, charges at Amara again but is easily deflected. Amara says "Goodbye nephew" and rips the archangel from his vessel, leaving Castiel unconscious on the floor.

In Alpha and Omega, Dean goes to check on Lucifer only to find Castiel. Castiel tells him that Amara ripped Lucifer out of him and he doesn't know what happened to Lucifer after that. Later, Dean tells Castiel he gets why Castiel agreed to possession by Lucifer and it was the right call even though it didn't work.

Season 12
In Keep Calm and Carry On, Lucifer is revealed to have survived and contacted with his followers. However, he has been severely weakened by the Darkness' attack on him and is unable to find a suitable vessel, jumping across multiple vessels and burning them out. Lucifer utilizes two demons to clean up his burned out vessels with Crowley following them in an attempt to find and kill Lucifer to reclaim and solidify his own position as Ruler of Hell while Lucifer is weakened.

Crowley eventually tracks the demons to a house where Lucifer has burned out all of the family members except for the son who he is currently utilizing as his vessel. Afraid the demons are being followed, Lucifer refuses to meet them face to face and they are killed by Crowley. Crowley figures out who Lucifer is using as his vessel, but by the time he tracks Lucifer down, he has burned the vessel out and moved on.

In Mamma Mia, Lucifer finds a new potential vessel in aging rock star Vince Vincente. Much as he did with Nick, Lucifer creates hallucinations to convince the depressed musician to give him permission to possess his body. Vince does so after Lucifer makes Vince believe he'll be reunited with his late lover. Lucifer quickly gets comfortable in his new vessel, being interrupted only once by one of Vince's band mates. After Lucifer informs the rocker that he won't be going to rehearsal, telling him he has plans, the band mate grows annoyed but Lucifer knocks him out of the room. Lucifer then smugly reminds him that he told him he had plans.

Lucifer quickly travels to Crowley's throne room where he confronts the former King of Hell. He marches up to the demon and tells him to get off of his furniture but Crowley just mocks Lucifer for his choice in a new vessel. Crowley then offers Lucifer a deal; telling him that Lucifer would be better off running Heaven in God's absence and should allow Crowley to deal with the demons. Lucifer seems to consider it for a moment before reminding Crowley that he could smite him into oblivion. Before it escalates, Rowena appears and puts a paralysis spell on Lucifer's vessel. The devil assures Crowley that the spell won't hold him for long before Crowley splashes acid into Lucifer's face, wanting to damage his vessel so Rowena could exorcise him and send him back to the cage. Lucifer overcomes the magic, however, showing off his wings before healing his vessel's injuries. Crowley flees in fear while Lucifer takes Rowena captive.

In The Foundry, Lucifer pays Vince's sister Wendy a visit and heals her of her paralysis as part of the agreement he made to get Vince's permission. Seeing that his new vessel is already beginning to show signs of decay, he orders Rowena to cast a spell that will ensure he can keep using Vince, as he finds that the vessel suits him. However, during the ritual, Rowena instead speeds up Vince's degrading process, much to Lucifer's fury. Proclaiming that Rowena can't destroy him, Rowena agrees, and sends both Lucifer and his rotting vessel to the bottom of the ocean.

In Rock Never Dies, Lucifer is drawn to a fossilized feather from his wings, which is in the possession of young wannabe satanists. Lucifer teleports to them, and uses the feather to temporarily heal his rotting vessel, which has deteriorated even more from his time in the ocean. One of the satanists recognizes him as Vince Vincente and Lucifer realizes that he could gain devotion using his vessel's fame. He travels to Los Angeles and quickly begins to boost Vincente's fame. He tests out the devotion of those close to Vince, even convincing a groupie to harm herself for him. When Lucifer is threatened by a music producer after he fails to properly portray Vince by not playing new music, he casually kills the producer and goes to a show his band is putting on for publicity. However, he notices that his vessel is beginning to decay again when he arrives.

Before the show, Lucifer tries to kill the rest of Vince's band but is interrupted by Castiel and Crowley. They ask why he's parading around as a rock star and he explains that it's fun, not wanting to have to deal with the baggage of being the devil. He then easily overpowers and beats down both Castiel and Crowley before taking the stage in front of a cheering crowd, where Sam and Dean are waiting. Lucifer prepares to slaughter the crowd but Dean fires a gun, forcing the crowd out. Lucifer keeps the Winchesters inside, surprised to see them. When Dean tries to use enochian handcuffs on him, he easily melts them off of his wrist. He stops another attack from Castiel before being questioned about why he is doing this after making up with God.

Lucifer explains that God apologized for abandoning him only to leave again immediately after. He felt that God used him to help defeat Amara but only for that purpose. Furious, Lucifer declares that there's no point in any of their actions anymore, that there is nothing of God's creation except people looking for distractions. He declares that he is going to just keep on smashing God's toys and making the Winchesters watch because he has nothing better to do. Vince's body begins to completely burn out, with Lucifer having overexerted himself inside of it. Lucifer doesn't mind though, saying he would just go onwards and upwards and leaves the rock star's body for good. With Vincente dead, Sam points out that Lucifer was dangerous when he had a motive, but now he could be even more dangerous just having fun.

Following the death of Vince, Lucifer begins seeking out vessels with power and influence in LOTUS. Lucifer first possesses Wallace Parker, the CEO of "just about everything" and moves on to Wallace's friend, the Archbishop of St. Louis when Wallace burns out. Lucifer's possession of the Archbishop is noticed by his staff and they attempt an exorcism, enraging Lucifer who slaughters them all. The Archbishop then burns out and Lucifer is forced to move on.

After the Archbishop's death, Lucifer is able to get consent from the President of the United States Jefferson Rooney in exchange for teaching Rooney how to make America more spiritual. As Rooney, Lucifer kills a Secret Service agent that interrupted his communication with his vessel within his mind in order to learn how to pose as the President. Knowing the Winchesters will be after him, Lucifer sends Rick Sanchez and the Secret Service to stop them and engages in sex with Rooney's lover, Kelly Kline. After Kelly tells Lucifer that he would make a wonderful father, Lucifer decides to conceive a Nephilim with her.

In order to return Lucifer to his Cage, Crowley kidnaps Kelly and he, the Winchesters, Castiel and Rowena convince her to help them. Kelly calls Lucifer and claims she can't have his child, prompting Lucifer to travel to her motel room with two Secret Service agents. After the agents confirm that the room is clear, Lucifer enters and Kelly reiterates to him that she can't give birth to his child. Lucifer tells Kelly that he will have to insist and begins strangling her. Sam then emerges from the bathroom and activates a sigil on the door, amusing Lucifer as they have fought many times. Sam then raises a hyperbolic pulse generator, causing Lucifer to go after him, but Sam activates it before Lucifer can reach him. As the generator begins to exorcise him from Rooney, Lucifer attempts to throw everyone with telekinesis, but Sam's sigil has weakened his powers to the point that it barely even affects them. Lucifer yells that it isn't over to Sam who tells him to "go to Hell." Finally, Lucifer is exorcised from Rooney in a cloud of white smoke by the hyperbolic pulse generator and Rowena casts a spell that sends Lucifer through the floor and presumably, back into the Cage.

Following Lucifer's defeat, Castiel discovers that Rooney survived Lucifer's possession and erases his memory of it. The Secret Service discover the Winchesters over Rooney's unconscious body and are believed to have attempted to assassinate Rooney due to Lucifer's manipulations, resulting in their arrest. Despite the dangers, Kelly decides to keep Lucifer's child and runs off on Castiel rather than get an abortion.

In First Blood, Rick Sanchez states that Rooney has no memory of the three days Lucifer possessed him for, though he believes the Winchesters did something to the President. After escaping Site 94, the Winchesters tell Sanchez and his boss the truth about how they saved the President from possession by Lucifer, but the two and the few other people with knowledge of the Winchesters' arrest are murdered by Arthur Ketch.

In Stuck in the Middle (With You), Lucifer is revealed to be trapped inside a cage located in Crowley's throne room he'd once kept Crowley in. Manifesting in the form of Nick, Lucifer taunts Crowley about the loss of the Colt and he tries to talk Crowley into believing the Winchesters, whom he had just helped out, don't really care about him and that they intend to turn their backs on Crowley. Crowley disregards his comment and tells him to "be quiet", adding the nickname "dog". Lucifer coldly retaliates that "dog" is not his name.

In Family Feud, Lucifer is chained to a chair and Crowley states that he had his demons examine Lucifer's Cage on the molecular level and replicate it in the form of chains. Crowley explains to Lucifer that when he was exorcised from Jefferson Rooney, Crowley had perverted the spell so instead of sending him to the Cage, it sent him to the body of Nick which Crowley's demons had found, repaired and improved so that he could be Lucifer's permanent vessel. Lucifer is amused, believing that the chains won't hold him long and informs Crowley that his child is alive, unlike what Crowley had believed. Lucifer listens with glee to Crowley's phone call with the Winchesters about Gavin MacLeod and asks Crowley for advice as a single parent.

Later, Lucifer senses that Dagon is with Kelly and calls out Dagon's name with a smile. In Somewhere Between Heaven and Hell, Crowley continues to taunt Lucifer until he is interrupted by two demons. While Crowley is away dealing with the escape of Lucifer's hellhound Ramsey, the demons enter and reveal they set Ramsey free to create a distraction to investigate Crowley's behavior. After making a deal with Lucifer for more power, the demons release Lucifer who immediately combusts them. When Crowley returns, Lucifer taunts him and beats on Crowley before displaying his wings. However, with snaps of his fingers, Crowley makes Lucifer's wings disappear and causes him intense pain. Crowley reveals Lucifer's true prison is his vessel while the chains were just decoration. Crowley tells Lucifer he will kill Lucifer's son in front of him and will only then just be getting started torturing him.

In The British Invasion, Lucifer checks in on Dagon to make sure she is keeping the baby safe, and hopes she won't fail him a second time. When Crowley returns, Lucifer behaves sad, broken and submissively. He surprises Crowley by licking the floor. Lucifer explains that being Crowley's pet is so much nicer than being with his deranged "little bro", meaning Michael. Believing that he has finally won, Crowley presents the submissive Lucifer to a crowd of demons. Lucifer pretends to speak highly of Crowley, but is secretly ordering said demons to obey him on pain of death. One demon, Drexel approaches him while Crowley is absent to observe his vessel, and while the demon admits he doesn't know how to undo the system that allows Crowley control over Lucifer, he will try to crack it. Lucifer kisses him in delight and puts his shirt back on.

In The Future, a still-restrained Lucifer communicates telepathically with Dagon and is enraged to learn that she has lost Kelly and his son to Castiel. Lucifer, who had promised to form a family with Dagon and his son if she succeeded in bringing him into the world, swears to bring eternal torment upon Dagon instead if she fails. Terrified, Dagon agrees.

In There's Something About Mary, Drexel finishes his examination on Lucifer's vessel and is able to reverse the polarity of the system, allowing Lucifer to gain control of Crowley's vessel. Later when Crowley visits Lucifer, Lucifer begins to control Crowley's actions, visibly shocking Crowley. After Lucifer gets out of his chains, Crowley tries to convince Lucifer to spare him, but Lucifer instead uses telekinesis to throw Crowley around as retribution for what he's put him through. After Lucifer starts cutting Crowley with an Angel Blade and uses it to (seemingly) kill him, he reclaims his position as Ruler of Hell. After changing out of his vessel's old clothing, and donning clothing similar to his old vessel Vince Vincente, he sets out to find his unborn son.

In Who We Are, Doctor Hess reveals Lucifer's escape to Sam Winchester shortly before she's killed by Jody Mills.

In All Along the Watchtower, Lucifer kills Rowena MacLeod to prevent Rowena from trapping him again.

Lucifer later tracks his son to a cabin where he faces off with the Winchesters and Crowley who survived his attack. The three lead Lucifer through a rift into an alternate reality where Dean attacks Lucifer with a machine gun loaded with angel-killing bullets given to him by an alternate version of Bobby Singer. The bullets do little more than cause Lucifer pain, but distract him long enough for Sam and Crowley to perform a spell to seal the rift with the intention to trap Lucifer in the alternate reality. As the Winchesters retreat to the rift, Crowley kills himself with an angel blade to complete the ritual. However, before the rift can close Castiel comes through and stabs Lucifer with an angel blade of his own. Lucifer survives and returns to his original reality to kill Castiel from behind. As Lucifer faces off with them, Mary Winchester dons Enochian Brass Knuckles and attacks Lucifer, knocking him back towards the rift. Mary knocks Lucifer through the rift, but he pulls her through with him. Moments later, the rift seals behind them, trapping Lucifer and Mary in the alternate reality.

Personality
"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."

- Lucifer's sense of betrayal

Lucifer was once the most beautiful and beloved Archangel 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, due to the Mark of Cain corrupting him into jealousy, 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. When Lucifer returned to Heaven, he listed the Salem witch trials, Nazi Germany, the atomic bombings of Hiroshima and Nagasaki and the 9/11 attacks as proof of mankind's unworthiness.

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 millennium. 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 Winchester, 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 Winchester's life on several occasions, and allowing Sam revenge against some of the demons that controlled his life. Despite this, Lucifer is largely manipulative and 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. Furthermore, 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. Lucifer is also arrogant and extremely vengeful, taking his betrayal and hatred out on the entire world without any remorse. 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 savagely 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.

Lucifer has a sense of humor equivalent to Gabriel and Balthazar, rare in many angels. He can be sarcastic and casually indifferent, usually a testament to his arrogance. This highlighted particularly in Sam's hallucinations of him, where he sees him as constantly shedding a snarky and wisecracking light on Sam's everyday actions. When reunited with Sam in Hell, Lucifer proves to have a comical side, going so far as to dance during a fight with his enemies.

While Lucifer is angry with God for imprisoning him, he feels that it's a family issue and that dealing with Amara is more important to the point that he is willing to put aside his differences with his father and the Winchesters to fight her after the torture Amara put him through. After seeing God for the first time in eons, Lucifer initially seemed uncertain on how to react, but soon began to act somewhat like a petulant child, demanding an apology and locking himself in Sam's room when he didn't get one. However, after God actually apologized and explained his behavior, Lucifer forgave him and the two reconciled their differences to the point that Lucifer not only fought for God, he tried to save his father from Amara despite how powerful she was.

In the aftermath of the war with Amara, Lucifer seems solely interested in maintaining power in Hell, refusing to let Crowley stand in his way. He displays cruelty towards everyone who slightly upsets him. However, he makes an exception with Rowena, whose powers he is dependent upon, until she manages to betray him. Although repeatedly regarded as "evil" by this point, Lucifer was generous enough to keep up his promise with Vince and heal his sister Wendy of her paralysis. Following his banishment by Rowena, Lucifer comes back vengeful against God, believing that God had only apologized to get Lucifer's help against the Darkness before abandoning him a second time. Lucifer is both angry and devastated by this, in near tears when explaining his reasoning to the Winchesters and Castiel. He now sees no point in any of God's creations and intends to do whatever he feels like, specifically stating that he has no other plan.

Lucifer's disregard for anyone but himself remains prominent as he seeks out influential humans as his vessels, eventually landing with the President of the United States. Simply for the fun of it, Lucifer takes the president's lover to his bed, and willingly conceives a child with her, the purpose of this is uncertain, though he expresses joy about finally creating something rather than destroying it. He is enraged when Kelly threatens to abort the child, and becomes even more furious when Sam expels him from his vessel.

As Crowley's prisoner, Lucifer remains confident, humorous and fearless as he does not believe Crowley will get what he wants from him. Even after being tortured, he merely puts up a front that he will submit to Crowley's rule. Although he claimed to have lost his purpose after God's abandonment of him, Lucifer seems to have regained it by focusing on his son. Lucifer also admits to one demon that he is not well-known for his patience.

Powers and Abilities
As the second archangel, Lucifer is one of the oldest and most powerful beings in the universe. Lucifer is described by Zachariah as "powerful in ways that defy description". He is far superior to all demons and to almost all other angels, except Michael, though still inferior compared to God, Death, or the Darkness. Because archangels are independent when cut off from Heaven, Lucifer maintains all his powers, despite having fallen. 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. Below are listed the powers he has demonstrated in the show.
 * Nigh-Omniscience - Lucifer has immense awareness of almost everything, as Sam has said, "I'm sure he knows a buttload we don't". He knows spells capable of binding the Horsemen to him, but he, according to God, didn't know about the Impala. He also did not know if there was another person, other than Rowena, who knew how to open his cage or the spell she used. Even while bound by chains that were designed to replicate the effects of his cage and seal away his powers, Lucifer could still sense the power and life of his unborn son.
 * Immortality - As an archangel, Lucifer has an infinitely long lifespan. He is among the first angels and already existed before the Universe itself, making him well over 13.8 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".
 * Invulnerability - Lucifer's vessel is impervious to most damage and injury. 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, showing him to be unaffected by extreme temperatures. Even after being shot with a hundred angel-killing bullets, Lucifer was unhurt.
 * 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 was also able to heal Castiel's body of the injuries suffered in their fight. When Crowley splashed acid on him, Lucifer quickly healed himself, leaving not even a trace of burns. Despite being stated to have been severely weakened by the Darkness' attack on him that expelled him from Castiel, Lucifer quickly recovered from the damage.
 * Immunity - Lucifer is one of only five things in creation that the Colt cannot kill. Lucifer is unaffected by natural diseases and illnesses. as well as to supernatural infections, such as the croatoan virus. Lucifer was even immune to Metatron's spell which burned all other angels wings. As an archangel, normal angel blades were not able to kill, or even harm Lucifer. In addition, he was far less affected then normal angels when punched by the Enochian Brass Knuckles.


 * BVZwumD_-_Imgur.gifLower Tier Nigh-Omnipotence - Being an elder archangel, Lucifer is unimaginably powerful and as he was once the bearer of the Mark of Cain, he was next to indestructible. He can very easily kill even the mightiest pagan deities. While still imprisoned in his damaged cage, he was even able to mentally reach from there to Earth where he caused a bush to burn and appeared in Sam's dreams. While regular angels are severely weakened in the presence of Enochian sigils and holy fire, he just erased them with his mind, while imprisoned inside it. The only beings more powerful than Lucifer are Michael, Death, God, and the Darkness.
 * Angelic Possession - Lucifer is required to use a willing vessel on Earth, like 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 and even then the vessel needs to be strengthened by drinking a significant volume of demon blood. However, he was able to possess Castiel's vessel for at least a short time without it exploding.
 * Angelic Vessel Possession - Lucifer can possess an angelic vessel which is already in use, as he possessed Castiel in his vessel. To do that, he needed Castiel's permission. Castiel's vessel was able to hold the immense power of an Archangel and the power of a seraph without any visible physical damage. However, despite this, Castiel stated that Lucifer using him as a vessel was destroying Castiel and burning through his vessel.
 * Superhuman Strength - As an archangel, Lucifer endows his vessel with immense strength, sufficient enough to having slaughtered and overpowered even the greatest of ancient pagan deities 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 one of the strongest beings in all of existence. As the second oldest archangel, he's significantly stronger than lesser supernatural beings. He was also able to overpower his younger brother Gabriel, another archangel. Humans are powerless against him in terms of physical might, as he once effortlessly threw Dean a few feet against the windshield of the Impala and beat him to a bloody pulp with only a few strikes. Although his archangel brethren are his equals, only Michael is his certain equal and superior in strength.
 * Super stamina - He and his vessel are unaffected by diseases and toxins. He does not tire, and does not require food, water, oxygen, or sleep to sustain himself.
 * Shapeshifting - Lucifer can change his shape into any person he wants. While in his cage, he appeared as Nick to anyone who visited him and while being exorcised from Castiel, his vessel briefly distorted into a likeness similar to Nick's. LuciferApporting.gif and Dean into the cage]]
 * Teleportation - As an archangel, Lucifer can travel almost 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.
 * Apporting - While he was unable to leave his cage in Limbo by himself, he was able to apport Sam inside it and later Dean and Castiel too.
 * Power Negation - Lucifer could prevent lesser supernatural creatures from using their powers, as Baldur and Kali were unable to teleport either themselves or the Winchesters when he arrived at the hotel where they were conferring.
 * Telepathy - Lucifer had complete access to Sam's memories and thoughts while he possessed him. While in his cage, he gave Sam visions of the cage and manifested himself as a young John Winchester in one of Sam's dreams. Lucifer was capable of holding telepathic conversations with Dagon even while restrained by Crowley's chains. While communicating this way, Lucifer's scream was able to cause Dagon great pain.
 * Empathy - Lucifer could read the emotions of his vessel.
 * Telekinesis - Lucifer is able to move objects and beings around with his mind with great ease. He uses both elaborate hand gestures and snaps of his fingers similar to Gabriel.
 * 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. He was also able to show Sam his memories and entered Rowena's dreams while he was in his cage.
 * 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. While bound by Supernatural Handcuffs, Lucifer heated them up to the point that they popped off his wrist.
 * 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.
 * Molecular Combustion - Lucifer can kill lesser beings by rendering them down to their molecules as he did Castiel, Nithael and Jofiel. He was also able to use this power to make Ganesh explode. He also used this power to turn two demons to dust. LucifersTelekinesis .gif to kill pagan gods.]]
 * Reality Warping - Lucifer reminded Gabriel that he taught him everything he knew about using this power, when the latter tried to use it to kill him. While in Limbo, he was able to make a song play out of nowhere with a simple snap of his fingers.
 * 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, if Castiel did not absorb the damage.
 * White Light - He once captured Castiel by disabling him with a burst of white light.
 * Mental 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. He later used this to torment and communicate with Nick to get his permission to possess him, appearing in the form of his wife. After the Cage was damaged by the release of the Darkness, he was able to project visions into Sam's mind to draw him to the Cage. Lucifer was able to project an image of Vince Vincente's dead lover before Vince to trick him into giving Lucifer permission to use him as a vessel and cause Vince to experience hallucinations.
 * Manifestation - Though lacking a vessel and without communicating in a dream, Lucifer was able to manifest before Sam, Crowley and Rowena in the form of the long-dead Nick.
 * Expert Hand-to-hand Fighter - Lucifer is a very skillful fighter. He was able to casually fight Dean, Sam, and Castiel (who he managed to also disarm) all at once, even while in his cage.
 * Chronokinesis - Lucifer possesses the power to travel backwards and forwards in time.
 * Soul Channeling/Soul Absorption - Lucifer possesses the ability to draw power from a human's soul to boost his own powers.
 * Healing - Lucifer was able to heal his vessel's sister of her paralysis.
 * Electrokinesis - Lucifer was able to turn off a fire alarm and turn on music with a snap of his fingers.
 * Biokinesis - Lucifer was able to kill a Secret Service agent by inducing a massive cerebral hemorrhage.
 * Power Augmentation - Lucifer's presence on Earth greatly enhanced the powers of Jesse Turner.
 * Pyrokinesis - Lucifer was able to set a bush on fire from the Cage.
 * Astral Projection - Lucifer is able to display his full wings in a flash of white light.

Weaknesses
Even though Lucifer is incredibly powerful in his own right and despite being the second oldest archangel in creation, Lucifer has weaknesses of his own, but has fewer in comparison to his archangel brethren.

Harming, Misleading and Trapping

 * Enochian sigils - Lucifer can't find people with enochian sigils carved in their ribs. Also he could be weakened by a variant of an enochian sigil.
 * Lucifer's Cage - This cell can hold Lucifer, without any internal means of escape, as it was designed to bind Lucifer's power.
 * Nick's Body (formerly) - Crowley had his research and development team study the composition of the cage and carve its runes and spellwork into every molecule of Nick's body. This not only trapped Lucifer in his vessel on Earth, but also made him vulnerable to Crowley's power.
 * The Colt - It caused him pain and he was knocked him down for a short time when he was shot in the head, but it can't kill Lucifer.
 * Angel Trap - He could be trapped by the angel trap.
 * Holy Oil - Holy fire could hold Lucifer for a short time.
 * Hand of God - The Hands of God contain enough power to harm Lucifer. A physical attack from the Rod of Aaron could fling him across the room. When Crowley absorbed the Rod's power and blasted Lucifer, it significantly hurt and weakened him.
 * Magic - Lucifer could be briefly restrained and banished by spells.
 * Weak Vessels - As Lucifer said, a vessel besides Sam limits his powers. In a weak vessel like Vince Vincente, Lucifer's endurance, immunity, strength and powers are greatly reduced.
 * Bible - Contact with a bible hurts Lucifer and burns his skin.

Beings

 * Primordial Entities - Death, God, and The Darkness can effortlessly kill Lucifer.
 * Archangels - Michael is strong enough to kill Lucifer.

Weapons

 * Angel Banishing Sigil - This sigil could banish Lucifer.
 * Archangel Blades (possibly) - An archangel's blade might be able to kill Lucifer.
 * Hyperbolic pulse generator - This device can expel Lucifer from the vessel that he inhabits.
 * Lance of Michael - It was created by Michael to slowly and painfully destroy Lucifer.

Characteristics
Lucifer's true form has so far only been depicted as an intense white light, usually shown while Lucifer is exiting or entering a vessel. When severely weakened, Lucifer manifests as a bright form of white smoke. His wings were revealed to be massive in size in comparison to Castiel's; unlike those of standard angels, Lucifer's wings arc outwards instead of upwards and are not broken like the majority of his siblings. Uniquely, Lucifer's eyes glow red instead of blue.

While possessing a vessel, Lucifer usually retains the vessel's appearance without altering it. His 2014 alternate counterpart however, dressed Sam in an all-white suit and combed his hair back. After possessing Vince Vincente, Lucifer made an exception and chose to re-dress Vince in black clothing, topped with a leather jacket.

After escaping imprisonment from Crowley, Lucifer finally decides to change Nick's attire, doning a leather jacket as he did with Vince.

Outside a vessel but within Hell or someone's mind, Lucifer usually takes the form of his first known vessel, Nick.

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, comes back as a secondary antagonist in season 7 along with Edgar and also returns as the secondary antagonist in Season 11 and the main antagonist in Season 12.
 * 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 five main vessels; Nick, Sam Winchester, Castiel (the latter of which is an angel possessing an empty vessel), Vince Vincente, Jefferson Rooney, and is currently once again possessing Nick.
 * 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 Helel ben Shahar, which roughly translates as "Morning Star, the Son of Dawn", a name which only appears once in the Hebrew Bible.
 * 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.
 * 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.
 * Lucifer is the first antagonist to be defeated by being re-sealed back in his original confinement while most other antagonists are killed in their inaugural season.
 * All the main cast members (with the exception of Mark Sheppard) have portrayed Lucifer at one point. Jared portrayed Lucifer twice in Season 5, Jensen portrayed Lucifer in Season 7 for a brief moment, and Misha portrayed Lucifer for half of Season 11.
 * Lucifer's irises glow reddish orange in O Brother, Where Art Thou? making him the first Archangel to show a special eye color similar to how Castiel and other angels' eyes glow blue. He later displays the similar glow after possessing Vince.
 * In the episode LOTUS, Lucifer's eyes start to glow pure red instead of reddish orange.
 * In the episode Family Feud, Lucifer's irises briefly glow blue after he is returned to Nick's body. It should be noted however, that the glow was faint compared to other angels, and was limited to his irises, while standard angelic glow starts from pupils before spreading to entire eyes.
 * According to Mark Pellegrino, Lucifer's wings are "hot pink and sparkly".
 * In The Devil is in the Details, Lucifer made a reference to the show Lucifer that premieres on Fox of that year when he said that maybe he would move to LA and solve crimes.
 * Lucifer's mischievous behavior does not differ too much from Gabriel's; as siblings, they're said to have spent much time together, in Heaven, and Lucifer taught Gabriel how to do advanced reality-warping tricks. Their long-term convenience may have influenced Gabriel to act more like his olden brethren, too.
 * Lucifer is the first angel in the series to possess another angel in its vessel, instead of another human vessel, by possessing Castiel. The fact that Jimmy Novak no longer resides in his body may be why Lucifer could possess Castiel, as Cas, with his grace, is acting as a proxy for a human soul that must give permission to have its body possessed.
 * Lucifer has been overpowered twice by his vessels: both Sam and Castiel have briefly overpowered his control over them. However, while Sam had full control and could freely move around, Castiel stated he had to use all of his strength just to prevent Lucifer from killing Sam and was clearly struggling.
 * Lucifer is the first archangel who is known to have been banished by the angel banishing sigil.
 * Lucifer also is the first angel and archangel that trapped twice by using Angel Trap.
 * Lucifer is the second Archangel to realign themselves with good, the first being Gabriel, and also the second Big Bad turned good in Season 11, the first being Metatron.
 * Like Gadreel, Lucifer has shown the ability to share control with his vessel at will. In We Happy Few, Lucifer was able to give control to Castiel like Gadreel once switched control with Sam Winchester. After Castiel spoke with the angels, he and Lucifer were able to switch again.
 * In We Happy Few, when Lucifer is expelled from Castiel, he briefly appears in the form of Nick as his true form is yanked out of Castiel.
 * Lucifer is the only Archangel to be the ruler of Heaven and Hell at the same time, albeit briefly.
 * As of Metatron's death, Lucifer is the only angel confirmed to have wings.
 * During Rock Never Dies, Lucifer used his powers with snaps of his fingers similar to Gabriel and God.
 * In LOTUS, when Lucifer possesses Jefferson Rooney, the effect is similar to the one seen when Castiel first possessed Jimmy Novak in The Rapture.
 * In LOTUS, Lucifer becomes the first named Angel or Archangel to conceive a child in the series.
 * Lucifer is the third angel who is possessing a vessel that has died and been specifically restored for him. The other angels are Anna Milton's human form and Castiel with Jimmy Novak, Anna's human form was restored by an unknown force while God recreated Jimmy Novak's body to act as Castiel's vessel. In Lucifer's case, Crowley's demons found, repaired and improved the body of Nick for Lucifer's use as his permanent vessel.
 * Mark Pellegrino believes Lucifer has developed a snarky sense of humor as a means to hide his own pain, and that his current greatest fear is having his son, Jack, prefer Castiel to him.
 * Lucifer is the second angel that has been a member of the main cast through various actors, and the first archangel, most notably by Misha Collins and Mark Pellegrino in episode counts.
 * With Crowley's death in All Along the Watchtower, Lucifer is currently the longest lasting antagonist in the series. He is now also the only main character who has not died. He is also the only Big Bad to neither die nor officially reform by the end of Season 12. The only other Big Bad left alive is Amara, who found redemption.
 * Season 4 is the only season where Lucifer somewhat appears, but is not a major antagonist in that season.

In Lore

 * The Devil is known by many names throughout different faiths: Lucifer (Latin for " 'The Morning Star' or 'light bringer'"), The Devil, The Serpent, Iblis, (in Islam) and Satan (Hebrew for "Adversary").
 * In different versions of Bible, they said Satan is formerly known as Samael and was the former commander-in-chief of the angels army before his fall from Heaven. Some versions said he was the older brother of Michael.
 * "Lucifer" is a transliteration of the Hebrew word heylel.
 * Although "Lucifer" is considered to be the name of The Devil, this is never explicitly stated in the Bible and is merely the result of various translations. "Lucifer" appears only once in the Hebrew Bible, in Isaiah 14:12. Here, a prophecy about the fall of a corrupt Babylon king is described. Those who believe the fall of the king refers to the Devil's fall from grace began the traditional belief that Lucifer is most certainly Satan and the Devil.
