|“||I'm not a child! I'm the son of Lucifer. I'm a hunter. I AM A WINCHESTER!||”|
Jack Kline (b. May 18, 2017 - April 25, 2019) was the son of Lucifer and Kelly Kline. He is the first and only known Nephilim to be sired by an Archangel. Jack was taken in by Sam Winchester and Dean Winchester who would teach him how to master his powers. During this time, Jack played a role in the resurrection of Castiel who he had chosen as his father.
Jack would leave the Winchesters and Castiel to go off to master his powers, in an effort to prove he is good he would search for a way to rescue Mary Winchester for her sons. Jack would be sent to Apocalypse World where he'd rescue Mary and they fight out off many angels to protect a human colony.
Wanting to free the Apocalypse World from Michael's reign, Jack would form a resistance composed of humans to stand against the angels.
In the months that followed, Jack would see many victories over the angels before he was reunited with Sam, Dean, and Castiel. Jack also met his biological father Lucifer and his uncle Gabriel. He was unsure of how to deal with this but decided to hear his father out and even got on good terms with him. Jack believed that with his father, he could defeat Michael. However, his close status with Lucifer raised concern from the Winchesters and they soon put a stop to it in the evacuation of Apocalypse world by leaving Lucifer trapped.
Lucifer however returned and offered to take Jack to the stars where they could go on a father-son journey cross the known universe. Jack at first accepted immediately but after seeing Lucifer's true malicious self he disowned him as his father. In retaliation, Lucifer stole Jack's grace, leaving him powerless. With Lucifer poised to destroy everything, Dean became the vessel for the Apocalypse World Michael and killed Lucifer in battle to Jack's great relief before Michael took control of Dean and departed, loose upon the Main Universe.
In the time after his loss of power, Jack spent time adjusting to being human as he waited for his grace to return. However, he also felt worthless as he couldn't stop Michael but overcame it by using his basic hunter knowledge to help out. It was also shown that he was experiencing an illness but didn't know what was causing it though withheld this from everyone. After Dean returned, Jack went on a case with him and did very well but his illness finally took hold. It was discovered because his grace kept his body intact, Jack's body couldn't sustain without it and he was dying. After being given grace of his uncle Gabriel and being helped by Rowena MacLeod, Jack's body was giving out. Jack soon died and went to Heaven but he left his Heaven to enter his mother's heaven where he finally connected with her. However, Jack was pursued by The Shadow who sought to claim him but because of the Winchesters and Castiel, Jack was resurrected and returned to Earth.
Later after a final confrontation with Michael he kills the Archangel before consuming his grace and restoring his powers.
However, Jack's soul had burned out and his actions caused the others to worry on his condition. When Jack killed Mary Winchester, he sought to redeem himself by creating new angels but it didn't help and he was locked away by the Winchesters. Jack escaped and roamed Earth before he was confronted by the Winchesters who intended to kill him but stopped. This resulted in God returning to Earth and personally killing Jack and plunging the world into chaos to punish humanity for the defiance. Jack was sent to The Empty where he awoke. His corpse is subsequently used as a vessel by the demon Belphegor to help the Winchesters after he escapes from Hell. However, Castiel smites Belphegor after learning that the demon intends to use the Winchesters to gain power for himself. This second smiting burns Jack's corpse into a charred skeleton.
While still in his mother's womb, Jack was shown to be aware of his surroundings. He glanced at Dr. Turner during an examination and actively chose Castiel as his new protector and guide, replacing Dagon and even going so far as to help Castiel kill Dagon.
Since his father is Lucifer, it is a general assumption that Jack is the embodiment of pure evil. This belief was originally shared even by his mother, who attempted suicide so that her child wouldn't be unleashed upon the world. Jack resurrected her, however, saving himself in the process. Kelly then became convinced that Jack could be good, and that the world needed him. Eventually, after the child helped him defeat Dagon, Castiel also became hopeful that Jack was good, and could make the world a better place. He even claimed to have been shown a vision of a future without pain, fear, or suffering.
Upon delivery, the baby rapidly ages and leaves his dead mother on her bed while he retreats to his nursery. When Sam discovers him, Jack is now an adult and smiles menacingly at the hunter.
Immediately after being born, Jack began searching for Castiel, who he saw as his father, and showed great confusion at the world around him. All that he appeared to know was that his mother was in Heaven and his father was supposed to be waiting for him, but nothing beyond that. While Jack possessed memories from while he was in the womb, he didn't appear to understand what they meant. Jack was shown to enjoy some simple pleasures such as eating junk food with Clark and using his powers to get them some more. Jack has taken to using the computer more often after Sam showed him how to use it and mostly watches videos or plays games.
Because of his own heritage, Jack has shown an at least somewhat sympathetic view toward those like him (mistaken to be evil monsters) as he connected with Mia Vallens, a shapeshifter who tries to help people. Jack comforted her after she expressed sadness that she wasn't able to help anyone and she accepted his words. He also showed some sympathy towards Kaia Nieves, a Dreamwalker who struggled to control her power (and could only go to the Bad Place). He later attempted to convince her that there can be more use to her powers as he helped her see other worlds besides the one she has seen. Jack was kind to the Witch Rowena MacLeod, despite having heard about her from Castiel, Sam, and Dean but this was because he wanted to thank her from her part in saving him and the refugees. However, he will call the beings who kill for pleasure a monster, as seen when he called the angels "killers" or the Gorgon Noah Ophis a monster.
After accidentally killing someone, Jack showed great devastation and remorse for his actions and left the Winchesters and Castiel because he was afraid that if he stayed, he would eventually hurt them. This act also motivated him to go out on his own and master some of his powers to prove he is good.
|“||He'll be so glad to see his three fathers cause as far as he's concerned they're his fathers. You, you're nothing to him, or me, or anyone now. Nothing.||”|
Jack was shown to see Castiel as his father instead of Lucifer due to what Kelly had told him about Castiel. After Castiel was resurrected and Jack met him, he was very to excited to see him and hugged his uncle. He also declared that he only sees the Winchesters and Castiel as his family and states that his biological father Lucifer as well as the angels, his other uncles and aunts, were nothing to him due to their ways. Even Lucifer himself (upon hearing from Castiel about Jack's view on him when Asmodeus was holding them prisoner and later being told by Rowena that he meant nothing to Jack) believed that Jack wouldn't give him a chance unless he came bearing gifts (causing him to resurrect a recently deceased Sam). Even Anael who had never met Jack predicted that should Lucifer and Jack meet, then Jack would meet him with nothing but contempt and could easily tell that Lucifer did not want to find him out of fear that this would happen. Jack's words regarding seeing Sam and Dean as family are supported by the fact that he protected Sam from being killed by a shapeshifter and saving Dean from being killed by an angel. He went so far as to attempt to find a way to rescue their mother Mary Winchester for the sake of Sam and Dean. Also, Jack bonded Mary in their time together in the other reality and even protected her from Kevin Tran's suicide spell. He also got along with his uncle Gabriel who was not a hostile angel like the others he met and even considered Gabriel's remarks on Lucifer. During his talk with Lucifer, he expressed interest in his grandfather God. Rowena even stated to Lucifer that to his son he was a stranger, while Castiel, Sam, and Dean were Jack's real fathers, this was supported as when a sick girl later asked Jack if Castiel was his father and he replied that he was "one of them" in The Scar. During his sickness, he bonded with Dean as if he was his father and enjoyed his time. While he was in Heaven, he grew attached to his mother Kelly Kline when meeting her for the first time and was happy that she felt the same about him. Jack even tried to defend her from The Shadow only to fail. When he was about to leave, he felt reluctant since he knew that he wouldn't see her again but gained closure after she told him to live a full life and confirmed her love for him by promising to wait for their next meeting. When he met his grandfather, he was shocked to see him but surprised at his desire for the Winchesters to kill him before he carried out the deed himself.
By the time he was about six months old, Jack had developed into a kind-hearted person who cared greatly for others. While in Bobby Singer's colony, Jack admired the people there for their bravery and even admitted to liking the place and wanting to stay. Jack went so far as to use his powers to entertain the young children of the colony who had been living a hard life by creating interesting shadow puppets for them. When Bobby ordered Jack exiled from the colony due to his nature as a Nephilim, Jack was hurt and confused by this rejection and by the angry way Bobby treated him when Jack tried to offer his help.
Following in Sam and Dean's example, Jack chose not to run and hide when ordered to by Mary but to help defend the colony because it was the right thing to do as he'd learned from the Winchesters. Further following in their example, Jack decided to save the remaining human population of Apocalypse World by killing Alternate Michael as it was the only way to stop his and the angel's genocidal war against them.
While originally not caring about Lucifer at all, Jack, despite being wary of him, decided to hear Lucifer out when he arrived at the Dayton outpost in Apocalypse World. Jack became fascinated by the things Lucifer told him and even came to call Lucifer "my father" despite previously claiming that Lucifer meant absolutely nothing to him. He seemed to have taken a much better view of his father after learning he fought against Michael to protect him, looking saddened as he contemplated the fact that Lucifer was probably dead and he seemingly sacrificed himself to protect Jack. While enamored by Lucifer's words and the idea of a father-son relationship with him, Jack came to see the truth about Lucifer upon discovering he killed Jack's friend Maggie, he rejected his father completely in favor of the Winchesters who Jack saw as his true family, not showing anything towards Lucifer except anger and contempt in the process. Despite this, however, somewhat similar to when Lucifer appeared shocked and even somewhat concerned as Jack is about to kill himself (showing his father still took little joy in his son's suffering despite having been disowned and having been more than willing to create another child after such rejection), when Lucifer died, Jack, while showing no signs of empathy for Lucifer's death, did not celebrate it as the Winchester's (who had held a grudge against him for years) did, looking not as glad about it as they were, but showed to be at least relieved and glad that Lucifer's plan to destroy the Universe had been stopped. This, if true, probably implied that while he had disowned and no longer saw Lucifer as his father, he still took at least no genuine pleasure over Lucifer's death, likely as unlike the Winchesters and Castiel, he held no actual personal grudge against Lucifer, or at least not one as significant as they did. He later showed some sympathy towards Castiel for his awkwardness in being around Nick, Lucifer's vessel, as it reminds him of Lucifer, claiming that being around Nick is hard for him too, possibly hinting that he does in fact hold some amount of disdain towards Lucifer. When fighting Michael, Jack declared himself both as Lucifer's son and a Winchester. Though Nick later tried to bring Lucifer back, Jack intervened and personally sent Lucifer back to the Empty rather than allow his father to be brought back.
Jack cares deeply about others and is bothered greatly when he can't save people or hurts people by accident to the point that he even has nightmares about it. At one point, Jack literally beats himself up after he lost his temper over the murder of Maggie and nearly strangles Nate (who he initially believed had killed her) to death as a result. Jack's protective instincts are in fact, so strong that he will retaliate or turn against anyone if they have hurt someone he cares about, as shown when he brutally attacked Michael when he attempted to kill Sam, Dean and Castiel, and later effectively disowned his own father for killing Maggie. He also fell into a deep rage, as Michael's monsters killed the hunters in front of him that forced him to use his powers to obliterate them, despite needing to conserve it to live. He also used his powers to fight Michael when he possessed Rowena and used his abilities to eject him from her and killed the Archangel.
Jack has shown a capacity for self-sacrifice. When Lucifer ordered Sam and Jack to fight to the death with the victor surviving, Jack rejected Sam's offer to kill Sam and live and the idea that he could defeat Lucifer and regain his powers. Instead, Jack, without hesitation, attempted to sacrifice himself in an act of suicide so that Sam could live on and continue the fight with his planned last words being to tell Sam that he loves everyone. He was only stopped when Dean unexpectedly arrived to fight Lucifer.
Because he mostly relied on his powers for everything, Jack felt lost in the weeks after losing them. Slowly, Jack began to feel insignificant because of the threat of Michael loose on the world and himself not being able to do anything to stop it. Jack's sense of being useless also became more significant when he struggled with trying to adapt to fight like a human until his powers return and felt completely useless when he failed in adjusting to it and was unable to help in the mission to save Castiel, which led him overpowered by the demons holding Castiel prisoner. This view of himself seemed to have faded away after he managed to save Lora, a girl who had her life taken by a witch who had been stealing her life force and he seemed to feel better about himself.
By the time of Dean's return from his possession by Michael, Jack saw the Winchesters and Castiel as his fathers and vice versa. Despite their rocky start, Jack became particularly close with Dean who taught Jack how to drive on the Impala when he was dying and Jack choosing to do fishing with Dean because he knew it was an activity that Dean had enjoyed doing with his own father. Dean's opinion of Jack was always shown to matter quite a lot to him with Dean's initial impression of Jack as a monster sticking with him even after the two became close, though Dean grew to regret this opinion. Even when furious with Jack over killing his mother, Dean ultimately couldn't bring himself to kill Jack despite Jack accepting and welcoming his fate. God considered Dean killing Jack to be a father killing his son, showing the depth of the relationship Jack and Dean had developed.
Because of Jack's desire to protect his loved ones, he can show a ruthless side to himself at times. This was seen when he threatened the Prince of Hell Asmodeus for trying to hurt Sam, Dean, and Donatello Redfield. He also blasted away the shapeshifter Buddy when he tried to kill Sam, protected Dean from angels, and killed Alternate Zachariah to save Mary. When alerted of the danger by Sam, Jack returned to the bunker and attacked Alternate Michael for his assault on his family and showed him no mercy as he prepared to act on his promise to kill him. He later acted upon this promise with no hesitation when he used the power of his soul to kill Michael and use the archangel's grace to restore his own powers, despite the risks of burning off more of his soul.
After burning off a large portion of his soul while killing Michael, Jack is shown to be quieter and more reserved then he once was, most likely due to whatever degree of soullessness he is now suffering from. Though not uncaring, he has stated he feels different then he did, though he is shown still to care for the Winchesters and Castiel, as well as others.
Since regaining his power, Jack's old personality of showing them off returns and when hanging out with teenagers, he couldn't help but show off. However, when he accidentally stabs a girl, his sense of guilt returned and he didn't want to have cause another fatality and immediately heals her. He was distraught that his actions caused the teens to become scared of him and his powers. At the bunker, he withholds the event from the Winchesters since he knew they would be disappointed in him and understood their secret wariness of him.
It is eventually revealed that Jack's soul really is gone since killing Michael and he has lost much of his morals as a result. Jack brutally killed Nick for trying to resurrect Lucifer, instead of doing it in a more painless way and in a moment of anger, lost control and accidentally killed Mary Winchester. Though Jack tried to correct his mistake by bringing Mary back, his hallucinations of Lucifer said that his guilt was merely a reflex left over from when he did possess a soul. As a result, Jack's subconscious manifested a hallucination of Lucifer to act as sort of his voice of reason.
After getting locked in the Ma'lak Box, Jack was distressed to be betrayed, but still couldn't bring himself to seriously harm or kill the Winchesters and Castiel. After seeing the effects of his making the whole world tell the truth and scaring his grandmother, Jack came to the belief that he truly was the monster Dean first saw him as since every time Jack tried to do good, even without his soul, he caused more harm in the process. As a result, when Dean tried to kill him, Jack accepted and even welcomed his fate, caring enough to want to cause no more harm even when he had no soul and admitted that he could no longer feel emotion such as love.
Upon birth, Jack took on the form of a Caucasian human young adult with dark brown hair when recalling his mother's words of the world being dangerous for an infant. Unlike any other being seen on the show, Jack's eyes glow gold. They often glow when Jack uses his powers.
When Sam discovered Jack hiding in the corner of the room, he was visibly frightened by Jack's somewhat creepy appearance. After he encounters Sheriff Christine Barker, Jack obtains an outfit.
Jack has also been shown with a large pair of angelic wings, which seems to be as big as those of Archangels. He once used them to shield Mary from the explosion Kevin caused, and he showed them after absorbing Alternate Michael's grace to show the others his powers are back.
After being smote by God, Jack's eyes are burned out. As a result, the demon Belphegor wears a pair of sunglasses while using Jack as his vessel. After Castiel smites Belphegor while he's possessing Jack, Jack's corpse is burned into a charred skeleton.
- "My mother, she said Castiel - he would keep me safe. She said the world was a dangerous place, that's - that's why I couldn't be a baby or a child. I - that's why I had to grow up fast, that's why I chose him to be my father."
- "Every time I try and do something good, people get hurt."
- I like it. I like nougat.
- Jack: I'm not going to talk. I'm going to listen.
- Lucifer: He's gonna listen.

- Jack's name is a medieval diminutive of John. Jack was used as a slang meaning "man". John, on the other hand, means "Jehovah has been gracious".
- In the initial drafts for the pilot episode, John Winchester was originally named Jack. This had to be changed when a real Jack Winchester was found to be living in Lawrence, Kansas.
- Another possible meaning for the name Jack is "Godly".
- A popular meaning to Jack from Hebrew and Judaic origins is "God is merciful".
- He is the second known Nephilim in the series, the other being Jane.
- Coincidentally, both of them have a 4 letter name that starts with J.
- He is also the first known offspring of an Archangel.
- He is the first and only known being to possess golden eyes.
- Just like Lucifer, his father, he is immune to angel blades.
- Sam had a misconception that The Antichrist was the child of Lucifer because of what he learned from the lore, but Castiel corrected that misunderstanding by revealing that Jesse Turner who was a half demon hybrid was the actual Antichrist in I Believe the Children Are Our Future. It wasn't until seven seasons later that the actual child of Lucifer would be conceived.
- According to Sam, Nephilim don't require nine months to be born, and he was born on May 18th which corresponds to All Along the Watchtower, Season 12's finale.
- When empowering Castiel and showing Kelly Kline a premonition, their eyes briefly glowed gold.
- He bears similarities to The Source's Heir from Charmed. Both are the unborn child of the show's version of or equivalent to the Devil, both are able to channel their powers from the womb and both play a role in the deaths of a powerful, apparently unstoppable demon, Dagon in the case of Jack and The Tall Man in the case of the Source's Heir. Both demons were also killed by a powerful fire ability that incinerated them.
- Andrew Dabb referred to Jack as someone with an "evil source", but he was technically a "blank slate".
- In Lost & Found, Dean refers to Jack as "Damien." This is a reference to the Antichrist from The Omen series of movies.
- In LOTUS, Lucifer and Jack's mother, as a result of carrying Lucifer's child, were both seen incinerating bibles on physical contact since Nephilim share similar traits to their angelic sire.
- However, in The Rising Son, Jack is seen reading and touching a bible without burning it on contact.
- Due to either his human or Archangel heritage (or perhaps both), Jack is capable of tasting as humans do, differing from angels and seraphs who taste on molecular level. This suggests that Jack's senses are developed beyond human, but not overdeveloped like those of an angel.
- According to Andrew Dabb, he is about three months old as of the Season 13 episode Wayward Sisters. Mary Winchester gives his age as around six months in Good Intentions.
- He is the first member of Team Free Will to meet Apocalypse World Michael.
- He is also the first male Nephilim to be seen.
- Jack considers his uncle Castiel to be his father rather than Lucifer. He also considers Sam and Dean to be his father figures as well. He has a particularly close father-son bond with Dean with God comparing Dean killing Jack to a father killing his son at one point.
- In Gods and Monsters, Jack meets his maternal grandparents for the first time though they were unaware that he was their grandson.
- As a Nephilim, it is unknown where Jack would go in death.
- From the Shadow's attempts to claim Jack, it seems Nephilim are sent to the Empty after death. However, the Shadow was also stated to believe that Jack belonged here due to his being half-angel and when he died, his soul went to Heaven instead of the Empty. It is unknown if the Shadow had already attempted to collect the other Nephilim that had already died or if they had gone to the Empty after they died or if the angels sent them there. Even after Jack's human soul was gone, he still ended up in the Empty following his second death.
- His first crush was Harper Sayles, though his interest left after she set a zombie on him but after he killed the zombie she has developed both romantic feelings and a vendetta towards him.
- Before having his grace extracted, Jack was Team Free Will's strongest member. Castiel stated Jack's grace would return to him meaning he will eventually return to that status.
- Out of all his powers, telekinesis was the power he used the most on-screen.
- He is the only non-primordial character to possess powers that are implied to be (possibly) comparable to (or possibly even stronger than) God as he managed to awaken Castiel from his slumber in the Empty, a place God is said to have no power over.
- In addition, Donatello, who had sensed the power of both God and Amara, stated that Jack may be the most powerful being in the universe, indicating not only is he more powerful than his grandfather but he is even powerful enough to surpass The Darkness.
- Although at his current level, God was able to kill Jack with a simple snap of his fingers, it is indicated that Jack has not reached his full potential, as God appears to be somewhat afraid of what he could do if he continued to increase in power, seemingly showing if Jack reaches his full power, he may be able to challenge and perhaps even overpower his grandfather.
- He is the second character to telekinetically force someone to kill themselves with an Angel Blade, the first being The Darkness, his paternal great aunt.
- Coincidentally, both of their victims were angels who tried (and failed) to capture them.
- Like the rest of Team Free Will, he has killed a Big Bad with his being the Alternate Michael.
- With this, he is third member of the group to kill an Archangel.
- He is the first character ever to be killed directly by God on screen. While God was mentioned to directly kill the Nephilim during the Biblical times, it was never been seen on screen.
- Jack died twice in the same season while other members of Team Free Will died in separate seasons.
