|~ Crowley threatening Sam and Dean.|
|~ Crowley's iconic quote when meeting with the Winchester.|
Crowley is an antagonist appearing on the TV series Supernatural. He is the most recurring villain of the series. He appears as an anti-hero for most of the series, but he was one of the main antagonists in Season 6 and the main antagonist in Season 8.
He is portrayed by Mark Sheppard, who also played Jim Sterling in Leverage.
Fergus Roderick MacLeod was born in the Kingdom of Scotland 1661 and was son of a powerful witch and Grand Coven member Rowena. Fergus never knew his father, as according to Rowena, he had been conceived during a winter solstice orgy involving multiple potential fathers she had not bothered to keep track of. What is known is that he was not a practitioner of witchcraft, which got Rowena cast out. Although Fergus learned magic and spells from his mother,He was also abused by her, with him recounting that she had once tried to sell him for three pigs, among other things. Rowena once said that Fergus was a smart child, and learned to walk before his first birthday. He also disliked wearing pants.
When Fergus went to grade school he started drinking Craig becoming his favourite Alcohol
At the age of 8, Fergus was abandoned by Rowena when she got in trouble with the Coven and left on her own. He held a grudge against her for centuries, being that she had always hated him.
Later in life, Fergus became an unsuccessful tailor and heavy drinker who sold his soul for three extra inches to be added to his penis. He also had a son named Gavin, whom he similarly abused. He beat and starved Gavin repeatedly during his childhood, worked him harder than their own horse, and refused to let him attend school out of loathing towards him and Gavin came to loathe him, too, believing Fergus thought of him as less than nothing. Fergus eventually died at around 63 years old, in 1723 at which point Gavin buried him and set sail for America, only to perish in a shipwreck.
Per his deal, Fergus's soul went to Hell, where he was tortured until becoming a demon. After becoming so, Fergus was renamed Crowley and became a successful crossroads demon, at some point rising to the King of the Crossroads. He was also Lilith's second-in-command and possibly her lover.
Some point after he possessed a "moderately successful" New York literary agent and became his preferred vessel.
Crowley is first mentioned in the Season 3 episode "Bedtime Stories" by the crossroads demon Sam summons as part of his attempt to force her to break the contract to Dean's deal. The demon explains that her "boss" holds the contract instead of her and that he won't let Dean out of it because he wants Dean's soul to go to Hell. She refuses to give out her boss's name when Sam asks for it. However, given that Crowley was first introduced as the King of the Crossroads and that this boss is referred to as a "he," it is most likely that the demon was talking about Crowley.
Crowley is referenced again in the season 3 episode "Time Is on My Side" when Sam and Dean interrogate a demon for the identity of the demon who holds Dean's contract. The demon doesn't give the information away because he fears retribution from Crowley, instead challenging Sam and Dean to just exorcise him, which they do. Later on, Bela refers to the one she sold the Colt to as a "he" and challenges Dean to find him, saying he might catch up to Crowley "eventually." She reveals to Dean that the demons she was dealing with (i.e. Crowley and Lilith) changed their deal with her after she gave them the Colt, forcing her to kill Sam as well in order to get out of her contract. She fails and is implied to be killed by a hellhound.
Crowley is mentioned in the Season 5 episode "The Real Ghostbusters" as being the demon to whom Lilith handed the Colt over after obtaining the weapon from Bela Talbot, in addition to possibly being Lilith's lover.
Crowley first appears in the subsequent episode "Abandon All Hope...," where Dean and Sam Winchester infiltrate his mansion on a mission to retrieve the Colt so they can kill Lucifer and stop the Apocalypse. They corner Crowley, but are captured by two of his henchmen. Crowley then draws the Colt and proceeds to shoot his henchmen dead, then leads the brothers into his office. He offers to give the Colt to the Winchesters, stating that Lucifer will eradicate all demons after he wipes out humans. Crowley then disappears to what he calls "all points nowhere," but not before insulting the brothers after Dean asks what will happen to him if he's discovered to have helped the Winchesters.
Crowley returns in "The Devil You Know", suddenly appearing in the Impala's backseat. After avoiding being stabbed by an irate Sam (who initially believes that Crowley gave them the Colt knowing it wouldn't work on Lucifer), Crowley reveals that Lucifer knows he (Crowley) wants him dead and that he (Crowley) has been in hiding for the past few months. He then offers to help the Winchesters obtain the remaining two Horsemen rings and aids Dean in capturing Brady, Pestilence's servant. Later, when a hellhound approaches, Crowley disappears but returns shortly after with his own, larger hellhound, whom he sics on the other hellhound to allow the Winchesters to escape with Brady. At the end of the episode, Crowley approaches Bobby Singer with an offer to reveal Death's location in exchange for Bobby's soul.
In "Two Minutes to Midnight", Crowley appears just after Bobby reveals Death's location to the Winchesters and Castiel, and Bobby and Crowley's deal comes to light (along with the fact that the two men kissed to seal the deal). Crowley reveals that he bought Bobby's soul as leverage against the Winchesters, whom he believes will kill him. Later, Crowley gives Dean Death's scythe so he can use it to kill Death, and accompanies Dean to Chicago, where Death currently is. Crowley finds the Horseman in a restaurant.
Crowley serves as one of the three main antagonists of the season (along with Raphael, and Castiel) with Eve as the secondary antagonist. In "Weekend at Bobby's", he refuses to return Bobby's soul as agreed, but is eventually forced to return it when Sam and Dean threaten to burn his human bones.
It is later revealed that Crowley only wanted Lucifer removed so that he could take his place as the King of Hell. After ascending to the throne of Hell, he changed Hell so that everyone there had to stand in line endlessly, going to the back of the line when they finally reached the front.
Crowley also resurrected Sam and Dean's maternal grandfather, Samuel Campbell, and got him to work for him in his quest to find Purgatory, in exchange for bringing Samuel's daughter Mary (Dean and Sam's mother) back to life. Samuel and his relatives captured monsters, which Crowley tortured to find Purgatory's location. Crowley forces Sam and Dean to work for him as well, saying that he will return Sam's soul if they do, claiming to have that kind of power as he is now King of Hell. Eventually, Sam and Dean work together with Meg to force Crowley to return Sam's soul, but Crowley admits that he can't return Sam's soul, leading Castiel to seemingly burn his bones and destroy him.
After the death of Eve, however, it is revealed that Castiel and Crowley faked the latter's death, as Crowley and Castiel are working together to find Purgatory so Castiel can win his war against Raphael in Heaven. However, in the Season 6 finale, Castiel betrays and tricks Crowley, and opens Purgatory on his own, absorbing all the souls there. Castiel kills Raphael, but allows Crowley to escape, saying that he has plans for him.
After the events of Season 6, Crowley goes into hiding from Castiel, only to be found by the angel-turned-deity soon afterwards. Instead of killing the King of Hell, Castiel lets Crowley continue his work in Hell under his supervision, stating he still needs a place to punish his enemies; Crowley reluctantly agrees.
After Castiel is dethroned, so to speak, and the Leviathans are set free, Crowley tries to ally with their leader Dick Roman, only to be rejected and have his entire race threatened. Fearing for his life, he later makes an uneasy alliance with the Winchesters and Castiel. The season ends with Dick's death and Crowley kidnapping the newly-called prophet Kevin Tran.
In "Clip Show", Crowley begins killing the people Sam and Dean saved from supernatural menaces over the years, using Chuck Shurley's Supernatural books to find said people.
In "Sacrifice", Crowley goes on a date with Sheriff Jody Mills, a friend of the Winchesters. When Jody begins choking on her own blood as a result of a hex bag made by Crowley, the Winchesters call Crowley and agree to stand down if he agrees to stop killing people they've saved. Later, Crowley meets with the Winchesters at Singer Scrap Yard, where Crowley displays an extremely long contract. Dean seizes the opportunity to handcuff Crowley to himself with shackles bearing a devil's trap, preventing Crowley from abandoning his human host.
Dean and Sam then take Crowley to an abandoned church, intending to use him as the third and final trial to close Hell forever (said trial calls for the one completing the trials to cure a demon). Crowley is bound to a chair, and Sam regularly injects him with his purified blood. Crowley manages to send out a message for help, and Abaddon arrives. However, rather than help, Abaddon tries to kill Crowley so she can take the throne of Hell.
Following Sam defeating Abaddon for the moment, he continues the process and it begins to work. As Crowley starts to become human, he begins expressing regret for his actions, asking Sam where does he start to confess. He also reveals he has always had a desire to be respected and loved, implying all his power-grabbing and egocentric actions are driven by this desire being twisted and perverted by his transformation into a demon.
However, Dean stops Sam before he can fully cure Crowley, as he's discovered the process will cause Sam to die.
In the season premiere "I Think I'm Gonna Like It Here", after the angels apparently refuse to answer his prayer to save Sam, Dean decides to turn to Crowley, whom he has locked in the Impala's trunk. He asks for Crowley to knock once for "yes" and twice for "no," then asks him if he's still alive. At first Crowley does nothing, but eventually answers "yes." However, before Dean can do anymore, an angel shows up and interrupts him and as Ezekiel offers his help afterwards, he no longer needs Crowley's help.
In "Devil May Care," Dean reveals to Sam that, instead of killing Crowley, he has him trapped in the Impala's trunk under a devil's trap as he believes Crowley will be useful. The brothers take Crowley to the Bunker, where they lock him in the dungeon and question him as to the names of the demons on Earth, pointing out that he had previously been close to being human again. Crowley, however, is unimpressed with their questions and tells them that they can't torture him more than he already tortures himself all the time. Sam and Dean then lock the dungeon and shut the lights to leave Crowley to reflect, which he does, remembering how he nearly became human.
Hearing Kevin in the next room getting a file, Crowley taunts him, causing Kevin to beat him with his fists and a sledgehammer. Crowley claims to Kevin that he never killed his mother like he earlier claimed, and that he will lead Kevin to her if he releases him. Crowley also tells Kevin that the Winchesters will use him and then discard him as there will always be more prophets. While Kevin considers releasing Crowley, he decides not to and leaves him in the dungeon.
When Sam and Dean return to the Bunker, Crowley reveals the names of two demons to them that he claims they would be doing him a favor by killing. Crowley offers them a deal: he has the names they want and they have the ability to help him with the things he wants. If they help him, he'll help them. He also tells them that he told them the names because he got enjoyment out of Kevin's predicament. Dean has Sam check on the names Crowley gave them while he stops Kevin from leaving, telling him that even if Crowley was telling the truth, his mother is dead in all the ways that matters.
Sam gives Crowley a pen and paper for more demon names, but Crowley refuses unless he can stretch his legs. Sam just leaves the paper and pen with Crowley and leaves.
In "Slumber Party," when the Wicked Witch of the West escapes, she finds Crowley and he has her write what she wants on the paper. When she writes "key," Crowley tells her that the Winchesters keep the keys in the kitchen. When Sam and Dean find him, he agrees to tell them what the Witch wanted in exchange for being allowed to stretch his legs. Sam releases him from the collar keeping him in his chair, but he stalls so Dean shoots him. Crowley shows them the paper and tells them what he told the Witch. Sam and Dean then leave him alone.
After the Wicked Witch is killed, Sam secures Crowley to his chair again and puts a pen and paper in front of Crowley again. When Crowley tries to get more out of him, Sam leaves without ever saying a word, leaving the paper for Crowley. Annoyed, Crowley mutters "bollocks."
In "Heaven Can Wait," Kevin tells Sam there is some smudging on the tablet, as if the scribe didn't want anyone to read it. Neither one of them cannot translate it, so Sam suggests they get Crowley to translate the tablet, but Crowley refuses. When Sam tries to reason with him, Crowley crumples the paper up and throws it in Sam’s face. Sam then threatens to give Crowley up to Abaddon, and Crowley asks for one phone call.
Crowley proves that he can read the translation, and Sam decides to let him have one phone call. Kevin says letting the King of Hell and Abaddon communicate with each other is a terrible idea. Since the phone call involves drawing blood, Sam starts to do it but Crowley demands Kevin’s blood, saying he's had enough of Sam’s blood and wants something fresh. After some coaxing, Kevin agrees and fills a syringe with his blood. With the blood bubbling in a bowl, Crowley contacts Hell; when he says he is their King, he is put on hold.
Crowley reaches Abaddon, who gleefully tells him that she has doubled his projections by voiding his contracts and bringing more souls to Hell. She then insults Crowley and tells him she will soon replace him. Crowley yells that she can't rule Hell with chaos and she will burn, to which Abaddon snarls she can't wait. Crowley passes the bowl back to Sam and asks for the transcripts, saying that he keeps his promises. He then reads the transcripts and gives Sam and Kevin the bad news: the angel-banishing spell is irreversible.
When Sam is washing out the bowl of blood, he notices something amiss with the set of syringes. Opening it, he finds one gone and realizes that Crowley palmed one of the syringes. Heading to Crowley, Sam sees Crowley injecting himself with Kevin’s blood and leaning back, sighing with relief.
In "Road Trap," after Gadreel takes complete control of Sam, kills Kevin, and leaves with the tablets, Dean asks Castiel for help, and Castiel reminds him of how the demons were able to dig into the angel Samandriel's mind, and tells Dean they might be able to bypass Gadreel and talk directly to Sam to get him to expel the angel possessing his body.
Dean then tries to bargain for Crowley’s help and offers him a syringe of human blood, believing Crowley has a craving for it, but Crowley refuses and asks for a massage by Kevin. After Castiel informs him that Kevin is dead, Crowley then taunts Dean, saying that people who get close to him get killed. He agrees to help Dean and Castiel crack open Gadreel in exchange for allowing him a little field trip with the chains still on. Castiel and Dean get into an argument about accepting Crowley's deal, and when Crowley then suggests asking for Sam's opinion, he sees Dean's reaction to Sam's name and deduces that it's Sam who's in trouble. Dean then agrees to the deal.
Crowley, Dean, and Castiel drive to a NSA listening post where Cecily, a demon who can track anything, is employed. Cecily insists on meeting Crowley alone in a warded room, thus making Castiel unable to listen in, then updates Crowley on the high points of the months he's missed; she admits that Hell is in chaos and that Abaddon hasn't yet taken over. She also implies that she is not totally loyal to Crowley, but that she is playing both sides. She then locates the Impala for Crowley.
Once Gadreel is captured, Crowley begins to access Gadreel's "programming" and is able to make the angel reveal his identity, but Crowley is still unable to bypass the angel and talk directly to Sam. Dean then asks for Castiel to posses Sam and help him kick Gadreel out, but Castiel can't possess a vessel without permission. Crowley then offers to do it if they remove the chains and set him free. Dean agrees and releases Crowley from his bindings, allowing him to jump into Sam's body. Once in Sam's mind, Crowley convinces him that an angel is possessing his body and he is tucked away in a small, dark corner of his mind, but then Gadreel finds them and a fight ensues. Sam expels Gadreel from his body, and Crowley leaves voluntarily.
As Sam starts to wake up, Abaddon arrives, and Crowley tells the Winchesters and Castiel to leave. Dean then says that this doesn't make them square and if he sees Crowley again, he is dead, which Crowley says he wouldn't have it any other way. He is confronted by Abaddon who orders her demons to kill Crowley, but they refuse and Crowley points out she does not yet rule all demons. Abaddon wants to fight, but Crowley likens their conflict more to an election; whoever wins over the demons will rule Hell.
In "First Born," Crowley, searching for the First Blade, the only weapon that can kill Abaddon, approaches Dean for help, revealing that the only demon who knew about the Blade was captured by Dean's father John Winchester before Crowley could get to him. Following a clue in John's journal, Dean and Crowley travel to John's lock-up where they find a file on an old case that John worked with a hunter named Tara where he interrogated and exorcised the demon who mentioned the Blade.
Crowley and Dean then find Tara, who recognizes Crowley as a demon and initially refuses to help until she is told about Abaddon. After Tara reveals that the last ingredient of a locator spell for the Blade is essence of kraken, Crowley takes off to get it. Using the spell, Dean and Crowley are able to track the Blade to Missouri. Upon arriving at the location the spell indicated, Crowley is terrified to find Cain, who prevents him and Dean from escaping by suppressing Crowley's powers. When Crowley tries to explain their presence, Cain silences him as Dean is impressed by this feat.
Cain reveals that he created the Knights of Hell and slaughtered them (which Crowley knew and didn't tell Dean), but refuses to give them the Blade. Four demons arrive to attack and Crowley kills one with an angel blade while Dean kills the rest. As an army of demons arrive, Cain agrees to help, gives Dean the Mark of Cain (the source of the Blade's power) and tells Dean and Crowley that the Blade itself is in the ocean. Cain then teleports the two outside as he takes on the demon army and they flee. Dean realizes that Crowley was actually using him all along, having known the truth about the Blade and Cain the whole time. Crowley confirms it, saying that while Cain wouldn't help him, he knew he'd help Dean. While Dean threatens to kill Crowley once they've dealt with Abaddon, the two are forced to work together for the time being as Crowley is the only one who can find and retrieve the Blade.
In "Blade Runners," Crowley has grown addicted to human blood and relies on a beautiful demon named Lola to get it, not knowing that she is betraying his secrets to Abaddon. After discovering Lola's betrayal and killing her, Crowley calls in Sam and Dean, who force him to detox from the blood. Crowley reveals that he tracked the Blade down from where it was retrieved from the bottom of the Marianas Trench years earlier, and helps the brother find who it was sold to by possessing the man sent to meet with them briefly. Sam and Dean learn that a man going by the alias "Magnus" got the Blade and realize he was one of the Men of Letters. Crowley reveals that "Magnus," actual name Cuthbert Sinclair, was a rogue member whom he had been trying to track down but lost track of.
Sam and Dean learn that Sinclair was once the Men of Letters' spellmaster and manage to convince him to let them into his secret lair, but Crowley is left behind. After Sam is sent back outside without Dean when Sinclair decides to add Dean to his collection of monsters and artifacts, Sam and Crowley work together to get inside Sinclair's lair. Once inside, though he is powerless, Crowley avoids capture and frees Dean, allowing him to kill Sinclair with the First Blade. However, knowing Sam and Dean will likely betray and try to kill him, Crowley steals the Blade from them until such time that they track down Abaddon and use it to kill her.
In "Mother's Little Helper," after Dean calls him and then hangs up, Crowley tracks him down at a bar and tries to convince him to embrace the Mark of Cain and the killer instinct that comes with it, but Dean refuses. While Crowley is using the bathroom, Dean stops a hunter from going after him and confronts Crowley as he believes Crowley was shooting up again with human blood. Crowley doesn't deny it, instead believing that Dean is hunting Abaddon so that he can touch the First Blade again and get the rush it gives him. Dean denies it, telling him he's focused on killing Abaddon and can't worry about the consequences of using the Blade, though Crowley is unconvinced. Crowley agrees to bring Dean the Blade when he finds Abaddon, but meets with the "hunter" Jake who was supposedly after him. It's revealed that Jake is actually a demon working for Crowley, who used him to test Dean to see if Dean would save him. Crowley is pleased, stating that he knew Dean would as they're "besties" and that Dean is "ready."
In "King of the Damned," Abaddon pulls Crowley's son Gavin MacLeod to the present to use his lingering humanity and affection for his son against him to force him to help her kill the Winchesters. After Abaddon causes Gavin great pain, Crowley soon agrees to her demands. Crowley reconnects with his son who is shocked his father is now a demon and berates him for his abuse. To get on his good side, Crowley tells he is the now the King of Hell and gives him the ability to read which pleases his son.
Crowley later informs the Winchesters of where to find the First Blade and helps by calling off a hellhound guarding it. He then tells them where to find him and that he has found Abaddon, but tells Dean "Poughkeepsie," the code word Dean taught him that means "drop everything and run" to warn him of the trap.
To keep Crowley from interfering, Abaddon shoots him in the shoulder with a bullet engraved with a devil's trap, binding his powers and trapping him. When Dean arrives, Crowley tells him that Abaddon is close, then warns him with his eyes of an attacking demon. Dean kills the demon and faces off against Abaddon while Crowley watches, immobile. As Crowley watches, Dean displays immunity to Abaddon's powers, allowing him to gain the upper hand and kill Abaddon.
Afterwards, Crowley uses a knife to dig out the bullet, annoyed that Sam and Dean won't help him. Sam informs him that they are letting him live and he should be happy with that. Crowley is amused to find out that Dean didn't tell Sam that he'd warned them it was a trap and is upset that Sam and Dean insist on sending Gavin back to his own time as Crowley doesn't want him to die. Pretending to say goodbye to his son, Crowley teleports Gavin to a park where he tells him of his fate and that he should build a new life in the present.
In the season finale "Do You Believe in Miracles?", having regained his post as King of Hell, Crowley is summoned by Dean, who's trapped inside the Bunker's dungeon by Sam and Castiel. He then informs Dean that the Mark of Cain's side effect is that the more you kill, the better you feel; the less you kill, the worse you feel. When Dean states that Cain was not affected like this, Crowley reminds him that Cain is a demon and that a human body is not strong enough to handle the Mark's power before telling Dean that, unless he keeps killing, he will die. Crowley helps Dean escape the Bunker, retrieve the First Blade and start hunting down Metatron.
During a brief stop in a restaurant, where Crowley insists that Dean order some food so that the waitress will get a bigger tip, he asks Dean if he ever wonders if "this" is all there is, and whether or not Dean has ever just wished to abandon it all and "go howl at the moon." He also states that he's kicked his human blood addiction, and that Hell is secure but complicated, to which Dean tells him that it's him that's complicated, not Hell. Before Dean can ask what they are, two of Crowley's demons enter the restaurant and inform him of Metatron's recent actions. Both Dean and Crowley leave, though Crowley asks Dean if he plans to eat his food, to which Dean replies that he isn't hungry.
Tracking down a woman that Metatron resurrected, both Crowley and Dean find Sam outside her house. Sam implores Dean to work with him instead of Crowley, to which Dean agrees and tells Crowley to go, causing Crowley to sarcastically quip that he's been "Winchester'd" and tell the brothers he would wish them good luck if he thought it would actually do anything.
After Dean has died from a fatal knife wound, Sam attempts to summon Crowley, not knowing that Crowley is already inside the Bunker with Dean's corpse. Crowley tells Dean's corpse that he has never lied to him, but he did omit certain truths or only half-tell them. He then says there is another story about Cain, that one day he realized what the Mark was doing to him and in desperation took his own life, but the Mark would not let him die. He then tells Dean's lifeless body that he isn't really dead but is entering a new life, where he will see what Crowley sees and feel what Crowley feels. He encourages Dean to open his eyes, which Dean does, revealing that he has become a demon.
In the season premiere "Black", Crowley is with Dean at a bar called the Black Spur. After Dean has sex with a waitress named Ann Marie, Crowley walks in on the two of them in his bed, and is upset with them for "soiling" his room. Later, Dean and Crowley play foos-ball with two people at the bar. They lose, and Dean blames Crowley for interrupting him while playing. When Dean almost kills a man who was harassing Ann Marie outside the bar, Crowley watches the whole fight silently.
When looking through the phone of an Abaddon loyalist by the name of Neely, Sam discovers a text that had alerted the demon of Dean's presence and whereabouts. When Sam calls the number, Crowley answers, revealing that he has been sending the "Abaddon loyalists" after Dean the whole time. Sam promises Crowley that he will save his brother or die trying, but Crowley tells Sam that he's jealous of the fact that Crowley and Dean are best friends now, and that his brother is not just possessed, but has been twisted into a demon by the Mark of Cain.
In "Reichenbach", Sam tracks Crowley using the phone number in the text message, which Crowley anticipates. Back at the Black Spur, Crowley tells Dean about Sam and that they have to leave immediately, but Dean doesn't agree. He then urges Dean to be his second-in-command and tells him that they could rule Hell together and be unstoppable. When Dean still refuses, Crowley admits that he sent that Abaddon loyalists, knowing Dean would make quick work of them, and that Dean needed to "feed" the Mark of Cain by fulfilling his newfound lust for killing. Crowley then tells Dean that he must decide if he really wants to rule Hell with him or not.
In "Soul Survivor", Crowley has gone back to ruling Hell, including sentencing to death demons that were loyal to Abaddon, as well as any demon that annoy him. When a demon questions Crowley's ability and competence in light of his time with Dean before immolating himself in front of Crowley and the other demons with holy oil, Crowley is shocked by the turn of events.
Crowley later learns of the angel Adina attacking Castiel (whom Crowley's been keeping tabs on) and Hannah, and he arrives at the gas station before Adina is about to kill Hannah. He slices Adina's throat and steals her grace before fatally stabbing her, then gives Castiel her grace, allowing him to power up again. Crowley tells Castiel the reason he helped him was because he wants Castiel to help fix the problem that is Dean Winchester.
In "Girls, Girls, Girls", Crowley is angered to learn that two of his demon minions, Gerald and Raul, went behind his back to create a demonic brothel to increase the number of souls in Hell by having people sell their souls for sex with hookers, as he finds it tacky rather than evil. After learning that Raul was killed, Gerald convinces Crowley to go after the witch that killed Raul. Later, Gerald reports to Crowley, saying that while their alpha team were killed by the Winchesters, the beta team caught the witch responsible. Crowley enters the dungeon to confront her and is shocked to find that the witch, Rowena, is his mother.
In "The Things We Leave Behind", Crowley is venting to Gerald about how horrible Rowena was as a mother when Gerald asks him why he just doesn't kill her, to which he answers he has his reasons. Gerald then offers to kill Rowena for Crowley, telling him he would have no problem with it as he killed his own mother over burning him with cigarettes, though Crowley doesn't give him an answer.
When Crowley finally decides to see Rowena, he berates her for being a terrible mother to him, but Rowena deflects that by saying she was motivating him for bigger things. When he brings up she abandoned him when he was eight years old, she tells it was because she ran afoul of the locals and had to flee. Rowena then tells Crowley she wishes to be a family again, and that he can trust her, unlike the demons who will turn on him at the first chance.
After their chat, Crowley and Gerald escort Rowena back to the dungeon. It's there that Rowena accuses Gerald of smuggling demons out of Hell, to which another demon, Trish, confirms. Gerald denies the accusations and begins to strangle Rowena. When he doesn't listen to Crowley's repeated orders to stop, Crowley stabs Gerald through the neck with an angel blade, killing him. As Crowley leaves the cell, he asks Rowena if she's coming, and she smiles and follows him out the door.
In "The Executioner's Song", Crowley presides over his court, extremely bored and playing games while a Crossroads Demon complains about not getting enough credit. While Crowley initially decides to give the demon the credit he wants, he instead takes Rowena's suggestion of cutting the demon in two. Afterwards, Rowena approaches him to help her eliminate one of her rivals, Olivette, which Crowley ultimately agrees to despite knowing her help before was so she could manipulate him into helping her with Olivette.
As Crowley plans an attack on Olivette with his mother, he is called by Dean, who tells that Cain is killing again and that he needs the First Blade to stop him. Crowley refuses at first until Dean tells him that Cain wants Crowley dead too. Crowley then retrieves the First Blade and goes to meet with the Winchesters and Castiel despite Rowena's objections that the Winchesters are using him and they are not his friends.
At a barn in Ohio, Crowley refuses to turn over the First Blade until they have Cain where they want him. Crowley, Sam and Castiel use Rowena's illusion spell to draw Cain into a devil's trap to weaken him for Dean to fight. Crowley then reluctantly turns over the First Blade to Dean after being promised its return if Dean returns in a sound state of mind. After Dean kills Cain, he hands the First Blade over to Castiel instead of Crowley, who is shocked that Dean lied to him. He is even more shocked when Dean reveals that he lied about Cain coming after Crowley, and Crowley disappears without a word.
Back at his palace, Crowley finds Rowena preparing to leave and she tells him he is no longer a king but the Winchesters' "lap dog" and "bitch," something that he is left considering.
In "Inside Man," after Rowena attempts to kill Dean and tries to deceive Crowley into thinking Dean beat her in hope of her son retaliating, Crowley ignores her and tells her she deserved what she got for going up against Dean.
Later, Crowley finds Dean and the two have a drink together. Dean schools Crowley about the meaning of family, saying it's not whether they're a blood relative or not, but how they treat you that matters. Crowley reveals to Dean that Rowena knows the Mark of Cain is a curse. He then returns to Hell and forces Rowena to leave, stating that the only reason she is clinging to him is because he is being useful to her. Rowena then packs and leaves her son's palace.
In "Brother's Keeper", Rowena puts an Attack Dog spell on Castiel to make him attack Crowley, and he stabs him with an angel blade; despite Mark Sheppard stating otherwise, it's revealed in Season 11 that Crowley survived by leaving his vessel before the stabbing.
In O Brother, Where Art Thou?, Dean and Sam approach Crowley in search for a way to contact Lucifer safely. They reveal to the demon that Amara was God's sister, which shocks Crowley. The trio come to the conclusion that they need the Book of the Damned to find the answer, so Crowley has his demons capture his mother, Rowena, to get her to read from the Book.
Once they have the instructions, Sam, Crowley and Rowena travel to Hell and into its deepest parts, where they intend to summon Lucifer into a warded cage. Crowley is the one to greet the Devil once he appears.
As Sam and Lucifer talk, Crowley watches from a distance with his mother. He becomes shocked and agitated when suddenly, the wardings fail, but Rowena calmly tells him to follow her, which he does.
Rowena reveals to Crowley in The Devil in the Details that she had been in fact working for Lucifer. Crowley becomes furious, but is unable to make her doing anything. He then calls Dean to inform of Sam's status, revealing to the distressed hunter that his brother is trapped with Lucifer.
Dean arrives in Hell shortly after, bringing with him a witchcatcher given to him by Billie for Crowley. Prior to this, Crowley had poisoned Rowena's tea, causing her to cough and give Dean the chance to place the witchcatcher on her. Crowley demonstrates his ability to command his mother, by telling her to hop on one foot, which she unwillingly does.
Crowley orders Rowena to cast the spell that will send Lucifer back to the Cage. He watches from his chair as Rowena obeys his command. With Lucifer seemingly gone, Crowley goes to meet Sam, Dean and Castiel and demands they all leave Hell, while he keeps Rowena with him.
As Rowena gives him a massage, Crowley asks why she hates him. She reveals that his eyes remind her of who she once was, a weak little girl, abandoned by his rich and married father. Crowley listens on quietly until "Castiel" appears. When Castiel tells him to guess again who it is, Crowley is bewildered to find that Lucifer had gained possession of the angel and is now out of his Cage.
When he tries to get up, Lucifer flings him against a wall and promptly snaps Rowena's neck, once he's confirmed only she can put him back into his Cage. Lucifer then sits across from the demon and tells him that they need to have a chat.Crowley's fate is revealed in The Vessel. Lucifer has reclaimed control over Hell and has tortured Crowley into becoming his "dog". Crowley is forced to wear casual clothes and is periodically kept inside a kennel. However, Crowley isn't completely broken, something Lucifer notices. Crowley correctly deduces that Lucifer, in contrast to what he told Sam and Castiel, is unable to defeat Amara alone and Lucifer does in fact require a team to win.
One day, the demon Simmons comes to his kennel and offers her assistance. Crowley manages to fight past two demon guards as they make their way out of the lair. Once free, Crowley dons a black suit and takes Simmons to his secret lockup, where he keeps valuable personal belongings. Crowley reveals to Simmons that he possesses the Rod of Aaron. He admits to finding out only recently that it was in fact a Hand of God. Before he can open the chest however, Lucifer appears at the entrance of the lockup, and reveals that Simmons was only pretending to switch sides. Lucifer wanted to rid Crowley of his last inch of defiance by making Crowley believe he could escape. Lucifer opens the chest, but discovers it empty since Crowley had the rod stashed elsewhere. Crowley hits Lucifer with the rod and absorbs all of its God-given powers. He tries to kill Lucifer with a blast of energy, but Simmons steps in the way and gets killed herself. With the weapon depleted, Lucifer attacks Crowley. Luckily, Crowley manages to escape after tumbling over a pile of books.
In Hell's Angel, Crowley visits a sick man named Noel and obtains the Horn of Joshua from him. Although the deal was that Crowley would tear up his contract, Crowley snaps Noel's neck and kills Noel's subordinates by having them fire their guns at each other. While trying to hide from demons looking for him, Crowley contacts Dean to talk about the Hand of God he now has. At a secret location, Crowley tells the boys his desire to use the weapon against Lucifer, in revenge for how he was treated. The brothers decline to take out Lucifer until they get Lucifer out of Castiel and defeat Amara first.
The trio soon receive a message from Rowena telling them she's alive. Rowena helps them set up a trap for Lucifer in order to bind him while they try to get Castiel to expel him. When the angel suppressing sigil fails, Crowley enters Castiel's vessel, where he discovers that Castiel is tightly under Lucifer's control. Lucifer, in the form of his former vessel Nick, proceeds to beat up Crowley. Crowley burns a massage onto the forehead of his own vessel to request assistance from the boys, writing "HELP ME". Sam and Dean work to exorcise Crowley, sparing him from death at the hands of the archangel. Crowley soon after flees the scene. After this encounter, Crowley makes a move to reclaim Hell and the throne, since Lucifer has been gone for sometime. Unfortunately, the demons do not wish to obey him, noting that he only makes "hollow promises". They all walk away when it becomes clear Crowley has no means to defeat The Darkness. Sulking, Crowley begins to drink heavily until Dean forces him to quit and accept a part in a battle against the Darkness, led by God. Crowley later meets up with Sam and Dean at a warehouse, where he encounters Lucifer and his mother Rowena. Crowley is then shocked to actually meet God, who states he was always rooting against him and his mother. Crowley is disgusted while watching his mother being flattered by God's words.
The trio argue over who is better between angels, witches and demons, with Rowena accusing Crowley of looking down on witches. When Amara finally arrives at their location, Rowena is the one to greet her and launch the first attack. The angels in Heaven blast Amara with a combined smiting, and the demons (in smoke form) gather around and attack Amara. Crowley exits the warehouse and joins the fight, plunging Amara into a nearby car in his smoke form.
He goes back inside following the aftermath of the battle, to find that they had lost, and calls it a "dog's breakfast". Rowena takes them outside to show them that the sun is dying, as a result of God's own condition. Crowley begins drinking inside the Bunker and shows no enthusiasm in trying to fight. When the team come up with the idea of using a soul bomb, Crowley goes to Hell to grab his stash of souls only to find that the demons had raided it in his absence. Fortunately, the reaper Billie comes to their aide and provides them with a large number of souls. Crowley shares flirtatious glances with Billie, much to the discomfort of his mother. The team decides to turn Dean into the bomb. Believing this to be his last moments, he bids everyone farewell, leaving them to go to a bar while he confronts the Darkness. Inside the bar, Crowley watches the news on television but turns it off once he grows tired of it. Sitting next to Rowena, he quietly eats nuts. He and the team are later made aware of the sun's restoration and they all go outside to check. They thus deem Dean's mission a success, and Dean himself dead.
Crowley seeks to reclaim the throne of Hell, but he is unhappy to discover that Lucifer is still alive and the demons are choosing their creator over Crowley. He tracks the archangel down for most of Keep Calm and Carry On, before seeking out his mother's help. He threatens to expose her true identity to her boyfriend Ben if she does not comply. Mother and son then await for Lucifer, who arrives inside his new vessel in Mamma Mia. Taking Lucifer by surprise, Rowena uses magic to paralyze Lucifer's vessel while Crowley weakens it with acid. Lucifer burns in agony but he soon recovers. With his plan unsuccessful, Crowley flees the scene.
In The Foundry, Crowley meets up with Castiel to join forces in tracking down Lucifer. Having searched Vince Vincente's apartment, Crowley discovered the location of Vince's sister Wendy. The demon and angel go to pay her a visit, but she is uncooperative, leading Crowley to threaten to steal her mobility, which was recently restored by Lucifer. Castiel insists on talking nicely, which helps them find out Lucifer's current whereabouts. However, Castiel is both shocked and disturbed when Wendy mentions Rowena.
Crowley explains to the angel how dangerous it is for Rowena to be by Lucifer's side, since he suspects she will give her services up in exchange for her life, like she always does. The two track Rowena and Lucifer to a cabin in the woods, where they only find Rowena, enjoying tea and the scenery. As the three leave, Rowena admits her hatred for Lucifer, which is why she will help them re-seal the archangel should they manage to corner him. Crowley and Castiel then resume their search for the archangel.
In Rock Never Dies, Crowley joins Castiel and the Winchesters in pursuit of Lucifer who has gone to Los Angeles to stage a concert in order to murder his vessel's fans. Once they have the location, Crowley and Castiel personally confront Lucifer backstage while Sam and Dean try to lure the fans away. Lucifer manages to gain the upper hand and severely beats Crowley with a guitar, giving him a black eye. Lucifer ultimately escapes, his vessel dead and the gang forced to pursue him again.
In LOTUS, Crowley continues to work with Castiel in tracking down Lucifer's next vessel. The four discover that Lucifer has taken the president as his latest vessel. While Sam, Dean and Castiel travel to the president's location, Crowley goes to retrieve his mother, only to find her arguing with her latest fiance, Louis. Crowley makes quick work of him and kills him instantly, and is a bit taken aback when Rowena says this is the nicest thing he has ever done for her. Mother and son share a smile.
With Rowena at his side, Crowley travels to the president's location and joins the other three in luring Lucifer into a trap so they can expel him from Jefferson and have Rowena cast a spell to banish him back into his prison. The plan is a success. Crowley then departs with Rowena, leaving the Winchesters at the mercy of the Secret Service.
In First Blood, Castiel informs Crowley that Sam and Dean have been imprisoned by the Secret Service. He implores Crowley to get his minions who work in the government to help free the brothers, but Crowley reveals that none of them are aware of the brothers' location. Much to Castiel's horror, Crowley chooses not to get involved since he knows Sam and Dean will find a way out like they always do.
In Stuck in the Middle (With You), Crowley sends two demons to stop the Winchesters, Castiel and Wally from attacking the Prince of Hell Ramiel, worried about the implications. While Crowley's demons kill Wally, they are in turn killed by the Winchesters. As the Winchesters and Castiel regroup in a barn, Crowley appears to warn them of what they have unleashed upon themselves by attacking Ramiel. Crowley realizes that Castiel has been stabbed with the Lance of Michael and warns that there is no cure. At Dean's urging and seeing the Winchesters as useful allies, Crowley attempts to talk Ramiel down to no luck and is thrown through the barn door with great force, knocking Crowley unconscious. After Sam kills Ramiel with the Lance of Michael, Crowley examines the Lance and realizes that its power comes from its craftsmanship. Crowley then breaks the Lance, saving Castiel's life.
Returning to his palace, Crowley panics over the theft of the Colt from Ramiel's house and is taunted by Lucifer who is now Crowley's prisoner in the same "dog cage" he once held Crowley in.
In Family Feud, Crowley talks with Lucifer over the latter's fate. Lucifer doubts things will go well for Crowley. When he mentions Kelly Kline, Crowley tells him that Kelly aborted his child, but Lucifer reveals his child is still alive, confirmed by the fact that he still can sense him. Crowley is angered, and when Dean calls him and asks to speak to Gavin, Crowley angrily refers to the brothers as "morons" for letting Kelly go. He also doesn't allow them access to his son.
Nevertheless, Gavin does meet with the Winchesters due to Rowena's help. When Gavin is informed that his fiancee is currently terrorizing various teachers as a vengeful spirit because she suffered torment while on board Gavin's ship (which Gavin failed to get on), Gavin decides to return to the past. He calls Crowley in order to bid him farewell, but Crowley is unwilling to let his son return to his death. Rowena paralyzes him with magic, forcing him to watch Gavin walk away, never to be seen again.
Crowley believes Rowena intervened for a dark reason, and Rowena explains that by allowing Gavin to die, she has paid Crowley back for the death of Oskar. She has forced Crowley to experience the loss of one's own child. Crowley is displeased to learn this, but also heart broken about losing Gavin.
In "Somewhere Between Heaven and Hell", two demons suspect Crowley is hiding something so they set Ramsey free from her kennel and try to divert Crowley's attention to other matters. When Dean calls Crowley about a hellhoundattack, Crowley leaves the palace to help him deal with Ramsey. This allows the two demons a chance to find Lucifer and free him of his chains. During the hunt for Ramsey, Dean thanks Crowley for saving Castiel's life. Once Ramsey is dead, both Sam and Ramsey's near-victim Gwen Hernandez thank Crowley for his efforts, with Gwen going so far as to hug him.
Back at his palace, Crowley finds Lucifer sitting on his throne. Crowley proves he has the upper hand by causing Lucifer physical pain without touching him. Crowley reveals that the chains weren't binding Lucifer, but his own vessel was, and it is now under Crowley's control. Crowley proceeds to torture a helpless Lucifer.
In "The British Invasion", Crowley has seemingly broken Lucifer who is now behaving completely submissive. Feeling he has done the impossible and will earn the respect he lost because of Lucifer, Crowley showcases Lucifer's new obedience towards him to a group of demons. Crowley is unaware however, that while Lucifer speaks highly of a King, he is secretly referring to himself and not Crowley, a fact which Crowley alone is left blind to. While Crowley is out doing his usual rounds, Lucifer calls for a demon to try to crack the system that grants Crowley control over his vessel.
In "There's Something About Mary", Crowley pays Doctor Hess a visit. The two don't see eye to eye completely, given Doctor Hess' low opinion of humans who sold their soul and became a demon. Crowley believes they can form a stable alliance. When Doctor Hess asks for one of his hellhounds, Crowley sends her one. This particular hellhound is used by the British Men of Letters to hunt down American hunters.
Crowley later gets a call from Sam asking about any missing hellhounds, since one apparently attacked and killed Sam's friend, Eileen Leahy. Crowley denies such, claiming he had been cuddling with the hellhounds the night before. Crowley finishes the call by telling Sam he doesn't care if a hunter was killed by one of his hellhounds.
Crowley returns to Lucifer's prison to inform the archangel that he wishes to make use of Lucifer. Since Lucifer is now his slave, Crowley hopes to use Lucifer's powers to decimate his enemies. Crowley also asks for the whereabouts of Lucifer's son, wanting to use the child's powers as well for his own benefit. He tries to goad the information out of Lucifer by informing him that with Dagon dead, the child and its mother has fallen into the hands of Castiel. Lucifer remains unfazed. When Crowley leaves the room, Drexel is shown hiding behind the door.
When Crowley returns to Lucifer's prison a second time, he discovers Lucifer now has control of his vessel. Lucifer uses his newfound control over the demon to torture him and seemingly kill him with a stab by an angel blade. After Lucifer's escape, the demons drag away Crowley's vessel to be disposed of. A rat follows them.
In "Who We Are", Doctor Hess reveals the escape of Lucifer and the apparent death of Crowley to a group of hunters including Sam and Jody.
In "All Along the Watchtower", Crowley is revealed to have survived by taking a rat as his vessel. Once the demons are gone, Crowley repossesses his buried vessel.
As the Winchesters attempt to locate Lucifer's son, Crowley appears in the bunker, drawing their ire as they have correctly surmised that Crowley was responsible for Lucifer not ending up in the Cage. Dean initially threatens to kill Crowley, but is convinced by Sam to hold off as Rowena is dead and Crowley helped her with the Cage spell and thus may know how to seal Lucifer away again. Crowley explains that he believed that with Lucifer under his control, he could finally win over those trying usurp his throne such as Abaddon. However, Crowley reveals that while possessing the rat, he had a lot of time to think and has realized he hates his job as King of Hell. Crowley offers to help the Winchesters defeat Lucifer at which point he will seal the Gates of Hell, leaving the only demon on Earth himself. After the Winchesters locate Lucifer's son, Dean pins Crowley's hand to the table with the demon-killing knife and orders him to stay put.
Crowley later appears at the cabin where Kelly Kline is with a bandaged hand and offers the Winchesters a solution to Lucifer. After drawing Lucifer through a rift into an apocalyptic alternate reality, Crowley performs a spell with Sam to seal the rift and trap Lucifer. Crowley then reveals to Sam that the final ingredient in the spell is the cost of a life.
As Lucifer attacked Dean, Crowley flung him away and faced off with Lucifer armed with an angel blade. Lucifer taunts Crowley about his inability to defeat him. Instead of attacking Lucifer, Crowley agrees with his statement before voicing his hatred of him and his anticipation to wipe away his smug smile. Crowley bid the Winchester's farewell as he stabs his chest with the angel blade, killing himself and completing the spell to seal the rift.
However, the rift takes a few minutes to seal, resulting in Lucifer killing Castiel and Mary Winchester ending up trapped alongside Lucifer.

- Numerous humans, demons, angels, leviathans and monsters.
- Crowley is similar to Lindsey McDonald from Angel and Cole Turner from Charmed, as the on and off villain of a monster of the week series.

- Mark Sheppard, who portrays Crowley in Supernatural, suggested in an interview that Crowley may not even be a demon, although this was disproved in the eighth season when Crowley's red demonic cloud form and red eyes (when he possessed Linda Tran were finally shown on-screen. And in season 10 his eyes were shown again via his original vessel.
- Crowley is the longest running antagonist for five seasons (two of which he is the main antagonist). However, he is notably the "weakest" main antagonist, as despite being the King of Hell, he is still a crossroads demon. Though, despite this, Crowley seems to not be easily killed and has obtained multiple means of killing angels, such as numerous angel blades and even angel bullets for guns, which arguably puts him on par with a regular angel now.
- Crowley is the most recurring demon in Supernatural, stealing the distinction from Ruby.
- Unusually, his true form's color is a dark red cloud rather than black like other demons, as shown in What's Up, Tiger Mommy?, Road Trip, Blade Runners, Out of the Darkness, Into the Fire, Hell's Angel, We Happy Few and All Along the Watchtower. This matches his eyes as his eyes are red due to being a King of the Crossroads previously. However, other demons with different eye colors do not match their true form, as shown with Azazel and Lilith.
- Crowley has assigned nicknames for Sam and Dean (which often reference Sam's height). For Sam these include: Giraffe, Gigantor, Jolly Green and (most commonly) Moose. He has also given Dean the nickname: Squirrel, and the name "Not Moose" in his contact list on his phone. Their respective "Squirrel" and "Moose" nicknames are a reference to Rocky and Bullwinkle, who are called "Moose and Squirrel" by their antagonists. In the episode "Inside Man" Dean combats this by replying "Boris. Where's Natasha?" referring to Rocky and Bullwinkle's nemesis: Boris Badenov and Natasha Fatele.
- He is the third character to be the main antagonist for two seasons, the first being Azazel and the second being Lilith; however, he is the first one to have a break seventh season between those two seasons in which he is not the main threat and to survive even after the second season that he was the primary villain.
- He is the second demon whose past as a human has been revealed the first being Ruby.
- In Weekend at Bobby's, he reveals that his favorite alcoholic drink is Craig scotch, aged at least thirty years.

- He is also hinted to have been in a relationship with Billie.
- Crowley also claims he owns "the real Mona Lisa" and to some extent Alaska.
- When Crowley calls the brothers, the number 666 flashes on the phone's screen. 666 is usually a number associated with the Devil. He also uses a devil emoticon while texting Sam.

- Crowley has been shown to be very good with obscure or difficult languages: he is fluent in Enochian and knows Elamite Cuneiform.
- Crowley, along with Azazel (who possessed Tessa), is the only known demon to possess someone at the same time as an angel.
- Crowley has stated that the host he uses most frequently is a "moderately successful" literary agent from New York.
- Crowley seems to have an affinity for Adolf Hitler and/or the Nazi Party. In Abandon All Hope... he is seen watching Nazi silent films in his mansion and in the Man Who Would Be King a Hitler-esque portrait of Crowley in a Nazi uniform with a Devil's Trident in place on his wrist band in place of a swastika was visible in Crowley's new and improved Hell. He also showed Amara Hitler speeches to "educate" her.
- Crowley has so far possessed six individuals: A "moderately successful" literary agent from New York (his most common vessel, Linda Tran, Sam, Andre Devlin, Marnie and Castiel. However, he only possessed Linda to get the demon tablet and Kevin, possessed Sam to warn him about Gadreel, possessed Andre only to get information, possessed Marnie to get in contact with his minions so they could secure his first vessel and break Rowena's immobilization spell on it, and possessed Castiel to try and bring him to expel Lucifer from his vessel.
- Crowley, self-admittedly evil, states he has no virtues, but this is not strictly true. He has exhibited Ambition (striving to ascend to becoming the King of Hell, Diligence (delegating a lot of duties to his underlings and taking up tasks himself frequently), Honesty (while he enjoys loopholes, he demands that all demons honor their deals and maintain "consumer confidence" as well as integrity, Loyalty (he is not prone to betraying those with whom he makes alliances, something he calls out Castiel for doing and Responsibility (commanding Hell's forces and fighting for the interests of all demons at heart as well as his own. However, Crowley has not truly exhibited patience.
- His name may be a reference to Aleister Crowley, an English Occultist, creator and self-proclaimed prophet of the religion Thelema who was born in 1875. He was denounced in the popular press as "the wickedest man in the world" and sometimes labelled a Satanist.
- His name also links to the crow, the bird of death, though this is unlikely connected to his character name and merely an amusing observation.
- When Gavin learned that his father had become a demon, Crowley quipped, "A lot can change in 291 years, "King of the Damned" implying that he had died as a human that many years ago. Assuming that the episode "King of the Damned" in which this information was revealed took place around the same time as its air-date (May 6, 2014), that would mean that Crowley died around the year 1723 and at around the age of 62, as he was born in 1661.
- Crowley displayed a possible fondness for Kevin Tran: when informed of his death, Crowley told Dean he warned Kevin it would happen if he didn't leave.
- While it is not known if his vessel was ever alive or was dead the entire time, after the events of "Out of the Darkness, Into the Fire", his vessel is dead for sure as Castiel stabbed it with an angel blade after Crowley vacated it. Despite this, Crowley was still able to return to his vessel, so it may have been dead the entire time.
- Like Meg and Abaddon, Crowley displays a fondness for a particular vessel, always returning to his usual form even after vacating the body for various reasons. Even after he was forced to flee his body in "Out of the Darkness, Into the Fire", Crowley had his demons remove the spell immobilizing his form rather than find a new vessel.
- When talking to Lucifer face-to-face, Crowley defined himself as "a mere acolyte, carrying Lucifer's torch", possibly indicating that Crowley holds some admiration for Lucifer's disturbed ideology and ways. However, this suspect gesture of humbleness may be just a product of Crowley's fear of the Devil, which makes pretty much sense, given that Crowley displayed to fear even the much weaker (than Lucifer) demon Cain very much.
- From his birth in 1661 to his death as a demon in 2017, Crowley was 356 years old.
- Mark Sheppard has expressed displeasure in his character's death scene in Season 12. Many fans have also expressed anger at the unfair treatment towards a long-lasting character and actor.
- Along with playing Crowley, Mark Sheppard also played the demon Arnon in the show Charmed.
- Season 12 is the only season Crowley has appeared in where he does not have a villainous role in at least one episode.
