> Jack explains his decision after becoming the new God, *Inherit the Earth*

**Jack Kline** (b. May 18, 2017) is 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 across 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 about 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 with considerable power 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.

To keep Jack safe, Billie keeps him hidden in the Empty until God leaves the Earth after recovering his full powers. Once God is gone, Billie resurrects Jack and provides him with a plan to eventually become strong enough to kill God, though he must hide and not use his powers until he's ready so as not to draw God's attention to him again. Initially resurrected soulless, Jack's soul is restored by the Garden of Eden after he visits through the Occultum. Jack later reveals that he is being turned into a bomb that will cause God and the Darkness to cease to exist, but which will also be fatal to Jack himself. After Sam prevents the plan from coming to fruition upon discovering that Billie is making a power play, Jack detonates in the Empty, but survives the experience. However, Jack is left powerless once more as a result.

Left as the only survivors upon an otherwise empty Earth, the Winchesters and Jack team up with Michael and, reluctantly, a resurrected Lucifer to defeat God. After the second death of Lucifer and the betrayal and death of Michael, Jack absorbs God's power and becomes the new God, the effort to turn him into a cosmic bomb having also made Jack a power vacuum that sucked up all of the power around him, including from the fights with Michael, Lucifer and Chuck. As the new God, Jack resurrects everyone that Chuck had wiped from existence, but decides not to take a hands on role in the world, feeling that that was Chuck's mistake. Jack subsequently releases Bobby Singer from Heaven's dungeon and with the help of a once again resurrected Castiel, reshapes Heaven for the better.

However, after Dean's subsequent death, a new threat emerges in the form of the Akrida, a failsafe left behind by Chuck to destroy everything in case he failed. Discovering this threat, Dean defies Jack's rules against direct interference to help the Monster Club stop the Akrida. Jack agrees to allow Dean's actions to slide and to finish his work before returning Dean and Bobby to Heaven.

## Personality

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 as the son of Lucifer, 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. This left Rowena flattered and she agreed to help him. 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. He also did not hesitate to kill the Grigori Sariel and smiling when he tells the last Grigori that he killed his brethren because of their feeding on humans.

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.
>
> Rowena to Lucifer, *Beat the Devil*

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. He got along with his great aunt The Darkness, despite knowing that he would inevitably kill her. He shared a high five with his aunt Serafina, after she showed him kindness.

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.

Following his second resurrection, Jack displays much of his original personality, though he still remains soulless. After seeing the plight of Kaia Nieves, Jack became determined to rescue her even though it put himself at risk. Jack later told Castiel that he remembered what it was like to feel things and it bothered him that he couldn't, that he could only remember and understand why he had felt such things. He also understood why the Winchesters were angry over Mary's death, but couldn't feel anything about it.

Following the restoration of his soul, Jack immediately burst into tears. Having regained his ability to feel, Jack felt immediate remorse for Mary's death and his role in it and begged for forgiveness. Jack later tells Castiel that he's convinced the Winchesters will only ever forgive him when Jack sacrifices himself to destroy God and the Darkness. As more time passes, Jack is shown to regain his old personality from before losing his soul, though he is somewhat more reserved due to the heavy burden left upon him. As before, Jack is shown to become easily excited by things such as Dean's idea of how to break through the dungeon door and taking a case. After realizing that they are dealing with a human monster, Jack seems disappointed that they likely won't be staying to solve the case anyway and then pleased when Castiel decides to finish the job since they can help. Jack shows a great deal of empathy throughout the case, connecting with Sylvia over the loss of her mother, offering her his help since Jack can sense the great pain he is in and even comforting Castiel while revealing that he must sacrifice himself to save the world.

After the failed attempt on God's life leaves Jack powerless, he is shown to be concerned about what comes next and the fact that Jack can't protect those that he loves in his current state. Jack also admits to not knowing what his purpose anymore is now that the plan and his destiny is over.

After Jack becomes the new God, he simply states that "I'm me" when asked if he's God now. Jack retains his usual personality, but chooses to remain hands-off on Earth, taking to heart the lessons that he has learned from the Winchesters, Castiel and his mother. However, Jack takes the opportunity to reshape Heaven for the better, resurrecting Castiel to help him in the task. He also sets free the Winchesters' surrogate father Bobby Singer whose alternate self Jack had been close friends with.

Jack ultimately adopts a sterner no-nonsense personality as the new God, instituting a rule that there will be no interference from on high anywhere with no exceptions in order to allow mankind to make their own fate. As a result, Jack doesn't intervene when the Akrida surface, even though they are Chuck's failsafe meant to destroy all of Creation in his absence. After Bobby gets Jack for help, he sternly admonishes Dean for breaking his rule to help the Monster Club stop the Akrida, but Dean defends his actions as necessary to protect their world and Sam who deserves a nice long life. Dean goes so far as to challenge Jack to cast him out of Heaven if he must for it, but after Bobby backs Dean up, Jack relents, although he looks conflicted even before he decides to let it go. Afterwards, Jack displays a glimmer of his old humor by telling Dean that "after this... it's time to get around to the "there'll be peace when you are done" part of the song" and he not only allows Dean to finish what he started, but he helps him out by giving Dean the Colt, possibly restored by Jack himself after Dagon seemingly damaged it beyond repair, to give to John and Mary. By this time, he and Dean appear to have mended their relationship to the point that Dean introduces Jack as family to the Monster Club. Jack may have also allowed Dean's detour through the Multiverse as Dean mentions that when he took his detour, he only had to follow Jack's rule about no interference. By not only allowing Dean to finish his meddling and providing him with the Colt, Jack indirectly gives John and Mary the chance to avoid their possible demise at Azazel's hands and prevent the chain of events in the Monster Club Universe that led to the Apocalypse in the Main Universe. Given the glimpse of Jack's old humor and his reaction to the reminder of Sam being in danger if Dean hadn't intervened, Jack's actions and rather gentle admonishment may have been Jack stepping back from his role as the new God for a moment to become the Jack that had been a hunter, a member of Team Free Will 2.0 and a member of the Winchester family again for a brief moment to help out those he cared about a final time.

## Physical Appearance

 File:Jack's Eyes 1301.gif
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 though he changes after reaching the bunker. Jack appears to be something of a creature of habit with his clothes as Jack is often seen wearing the same outfit or same kind of outfit for extended periods of time such as Jack's time in Apocalypse World. When he was in the Empty, Jack's essence wore the outfit that he died in.

 File:Jack's Wings 1414.gif
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. Upon his resurrection, Jack's body is restored to normal by Billie.

## Trivia

* 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*, 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, as well as the first male Nephilim.
	+ Coincidentally, both of them have a four 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, Jack 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 Jack was 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*, Jack's fingerprints are shown to be different from those of a regular human's.
* 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.
* Jack is capable of tasting as humans do, differing from angels and seraphs who taste on a molecular level.
* 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 the Apocalypse World Michael.
* 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.
* His first crush was Harper Sayles, though his interest left after she set a zombie on him. However, after he killed the zombie, she developed both romantic feelings and a vendetta towards him.
* Jack is Team Free Will's strongest member.

 File:Jack's Wings.gif
As a Nephilim, Jack is one of the most powerful beings in all of Creation; however, as the son of a human and an archangel, Lucifer, the Devil himself, Jack's power far exceeds that of any Nephilim. It has been stated numerous times that Jack possesses unimaginable power and according to his father, his power is "a chip off the old ball of heavenly light". Doctor Hess claimed the child could destroy the entire universe in an instant with a mere thought. At full power, he is immeasurably more powerful than any angel. The angel Miriam stated Jack could do "almost anything". The prophet Donatello, who has been in the presence of God, Amara, and Lucifer, initially mistook Jack for God when sensing his power, as it was "not dark, not toxic", unlike Lucifer's, yet still immensely powerful. Even before he left the womb, Jack was able to grant Seraph Castiel the power to effortlessly overpower and incinerate the Prince of Hell Dagon and force another Prince of Hell Asmodeus to flee when he became enraged. It was eventually revealed that, according to Nephilim lore, Nephilim become much stronger than the angel who sired them, meaning Jack will eventually become much more powerful than Lucifer himself, his angelic sire. His power is so great he was able to awaken Castiel, who had been sent to The Empty, which the Shadow, the ruler of the Empty stated it is supposed to be impossible to do that and has never been done ever before. Most recently, Asmodeus described Jack as an entity of infinite power and limitless capabilities, and the angels state Jack may be powerful enough to produce new angels, something that hasn't been done since God created the original angels. Even Jack is able to overpower, harm and kill Archangels, who are unimaginably powerful beings of nigh-omnipotent power and ancient primordial beings of over 900 centillion years in age, as evidenced by his encounters with Lucifer and the Archangel Michael's more powerful counterpart. Following his use of telekinesis to stop the Shapeshifter Buddy, Jack gains a greater control over his powers, particularly telekinesis. In *The Bad Place*, Jack has a more advanced control and use of his powers after practising with them. Jack also has very common angelic traits such as the ability to hear "angel radio" and prayers sent to him directly.

In *Let the Good Times Roll*, Jack had some of his grace removed and absorbed by Lucifer, leaving Jack powerless. It was revealed by Castiel in *Stranger in a Strange Land*, that Jack's powers are not truly gone and will slowly return to him as his grace recharges but its unknown exactly when. Castiel also believes that Jack's human heritage is interfering in the process of his grace returning. In *Ouroboros*, Jack absorbed the Alternate Michael's grace returning him to full power, although he had to burn off his entire soul in order to kill him. When his powers were restored, Jack displayed his full angelic wings to show he was himself once more.

After his second resurrection in *The Gamblers*, Jack retains his powers but doesn't use them as it will draw God's attention. He also displays enough control over his powers at this point that he can purposefully prevent his wounds from healing, a previously automatic aspect of his powers. Eating angel hearts and regaining his soul strengthened Jack's body. In *Last Holiday*, Mrs. Butters states that Jack has grown so unbelievably powerful to the point that she thinks the Winchesters should fear him. Jack later explains that Billie's spells are turning him into a bomb, or something like a "metaphysical supernova" that would collapse into a living black hole for divine energy from which even God and the Darkness couldn't escape, but would also kill him in the process.

In *Despair*, Jack survives the detonation, but he is left powerless once again as a result. However, as revealed in *Inherit the Earth*, it has the effect of Jack becoming a sort of power vacuum, absorbing energy from around himself. After absorbing enough power from Michael and Lucifer’s fight, their deaths and when God fought the brothers, he regained his nephilim abilities and became capable of stripping God of his power.

* **Nigh-Omnipotence** - As the Nephilim child of the second oldest Archangel, Jack is an unimaginably powerful entity, described as holding infinite power by Castiel. Even while unborn, he could still perform feats of great power such as resurrecting and healing his mother when she attempted suicide and even granting the Seraphim Castiel the power to effortlessly kill the Prince of Hell Dagon. After being born, Jack is deemed capable of achieving almost any feat he desires by Miriam. He was so powerful that while not even in the same realm, he awakened Castiel from his eternal slumber inside the Empty, something that has never been done before and was deemed impossible by the Shadow. The Angels also considered Jack's power almost as immense as God himself, and as being so great that he is capable of creating more Angels. Castiel stated that Jack will become stronger every second of every day and soon will become strong enough to destroy all life in existence with a snap of his fingers, and Castiel stated that that’s just the “tip of the ice berg of his true power” Additionally to being sired by the second oldest and most powerful Archangel Lucifer, the Devil himself and therefore inevitable to become far more powerful than he is, Jack's power is so great that he has shown the ability to effortlessly defeat and kill even the Archangels, as shown by how he was easily able to overpower and later killed Alternate Michael, who was the most powerful archangel to appear. This feat is made all the more impressive by the fact that Jack was relying on the power of his soul at the time, and was weaker than he would have been when he still had his grace, though the power this required resulted in his soul fully burning away, rendering him completely soulless for a time. Due to his power, most angelic weaknesses that would affect angels, other Nephilim and even the Archangels have barely any effect on him and even on most extreme occasions, he has been seen to still retain a certain amount of resistance to them. During *Peace of Mind*, Donatello Redfield stated that the now fully powered Jack is the most powerful being in the entire universe. In *Moriah*, after Jack escapes the near impenetrable Ma'lak Box, the Winchesters suggested that he "leveled up," somehow becoming even more powerful than he already was in order to escape from the box. Even highest-level Primordial Entities such as God have been shown to be afraid of his growing power, with God even deciding to ditch his caring façade just to kill him effortlessly while he still could, and Billie confirming Jack could kill not only God but also The Darkness by transforming himself into a bomb that would destroy them. After Jack survived his explosion and became a power vacuum, from absorbing the power from Michael and Lucifer’s fight, their deaths and when God fought the brothers, his power was not only restored but also magnified to levels where he was able to easily overpower and strip God of his power.
	+ **Astral Projection** - Jack was able to project his awareness into Michael's fortress to discover that it was in fact empty. He also can show his wings.
	+ **Banishing** - Jack managed to effortlessly banish Lucifer back to The Empty.
	+ **Biokinesis** - Jack was able to easily inflict pain on Michael that was enough to damage his vessel and bring him down to his knees, leaving him severely weakened and unable to fight, a feat never seen before even Lucifer was shocked. While killing Nick, Jack caused his fingers to break just by clenching his hand.
		- **Rapid Aging** - Soon after birth, Jack willingly accelerated the natural aging process of his body to quickly become a young adult.
	+ **Supernatural Perception** - Jack could perceive the true form of angels without any ill effects. This was best seen when he identified the Alternate Michael in their first meeting.
	+ **Clairsentience** - While experimenting in attempting to open a Rift to Apocalypse World, Jack was able to feel the Alternate Realities. He was also able to identify who Michael was when he first saw him. While in Heaven, Jack was able to tell something was amiss and left out. Naomi stated it was because of his angelic heritage that let him detect it. After his powers were restored, Jack was able to feel that injection Nick had used on Donatello was previously filled with angelic grace. Even while he was powerless, Jack was able to sense another presence, something beside him and the Winchesters still in the world after God erased everyone.
	+ **Conversion** - As seen in *Jack in the Box*, Jack is able to forge human souls into angels.
	+ **Conjuration** - In *Jack in the Box*, Jack was able to make worms appear inside a priest's body.
	+ **Electrokinesis** - Jack's labor caused a power outage. In his normal state, he also able to affect the works of machinery and electricity, such as lamps and a vending machine. When scared, he also can cause electricity to go haywire. He was able to turn off the engine of the Impala.
	+ **Healing** - From the womb, Jack was able to heal Kelly Kline's slit wrists and massive blood loss. While empowering Castiel, he also healed the angel's injuries from the fight with Dagon in a manner of seconds. Jack was later able to heal Stacy after accidentally stabbing her with an angel blade. He later healed Sam's serious head injury from Nick bashing his head in with a rock.
	+ **Illusion** - To entertain some kids, Jack was able to alter the shadow puppet shapes he was making to look like whatever he wanted.
	+ **Localization** - Jack was able to locate Lucifer and Castiel at the camp. He also tracked Sam's location to the Men of Letters bunker when he prayed to him.
	+ **Molecular Combustion** - When Jack and Kaia combined powers to open a rift to an alternate reality, Kaia's screams caused the rift Jack was opening to emit a yellow glow that caused six nearby angels to turn to dust. After lifting Zachariah into the air with telekinesis, Jack was able to cause Zachariah to explode simply by clenching his fist. By sending energy pulses similar to his telekinesis into the air, Jack caused three more angels to explode in mid-air. In a moment of anger, Jack accidentally used this power to obliterate Mary Winchester, leaving an angelic blast site behind and no body. Duma stated that her death was instant and painless.
	+ **Photokinesis** - When Jack was born, his birth caused him to emit a yellow blast of light that briefly knocked a nearby Mary Winchester unconscious.
	+ **Portal Creation** - Jack's birth was able to open a rift into an alternate reality. Jack later experimented in attempting to open a door to rescue Mary from the alternate reality but determined that while he could feel around, he needed a dreamwalker in order to be able to see the realm. When combining his powers with Kaia like this, due to her flashing between Mary and the Bad Place, Jack transported everyone to three different locations: Kaia to a roadside, himself to Mary and the Winchesters to the Bad Place. This effort also opened a rift to the Bad Place though not to Apocalypse World. The rift Jack opened to the Bad Place was also strong enough to last for a number of days while a rift opened by the ritual from the Demon Tablet only lasts for twenty four hours. Zachariah said **Jack** is strong enough to open a portal big enough to march an army through. When opening a rift to the Bad Place following his second resurrection, Jack is able to do it simply by extending his hand and concentrating, not requiring the help of Dark Kaia and her dreamwalking powers. However, he had dreamwalked through Dark Kaia to the Bad Place a short time before and so may have not needed the extended connection to open the rift.
	+ **Power Granting** - From the womb, Jack was able to temporarily empower Castiel to the point that he was able to overpower and kill the Prince of Hell Dagon.
		- **Super Strength** - While empowering Castiel, he granted him enough levels of superior strength to effortlessly overpower the Prince of Hell Dagon, who had easily beaten Castiel while he was only using his seraphim powers.
		- **Power Negation** - While empowering Castiel, he granted him the power to render Dagon completely powerless.
		- **Pyrokinesis** - While empowering Castiel, he granted him the power to burn Dagon, the Prince of Hell, to ashes.
		- **Invulnerability**- Jack was able to protect Mary from the suicide bomb spell of Kevin Tran using his wings.
	+ **Pyrokinesis** - Jack burned Nick to death from the inside, leaving the outside of his body scorched.
		- **Thermokinesis** - After Jack was born, his footprints scorched the parts of the floor of Kelly's cabin he had walked on. When he and Kaia open a rift together to the Bad Place, the wave of energy Kaia's screams released from the rift Jack was opening was able to heat up the angel blades of six nearby angels to the point that they became half melted into the floor. He was later able to heat up the bars in the warded window of a cell in Michael's fortress to the point that they melted.
	+ **Reality Warping** - Under the guidance of a disguised Asmodeus, Jack was able to open a Hell Gate to an almost inaccessible section of Hell to release the Shedim. However, doing this required Jack's full concentration and when his concentration broke, the Hell Gate closed. He also managed to remove blood stains from his shirt by simply waving his hand over them. In *Game Night* Jack managed to effortlessly close the portal to The Empty.
	+ **Resurrection** - At the same time he healed his mother's injuries, he resurrected her. However, Miriam indicated that, despite his vast power, Jack is not powerful enough to resurrect Castiel as he is "all the way dead". Jack has never displayed this power on his own outside of the womb, relying on Lucifer to resurrect Maggie and trying to use a spell to resurrect Mary Winchester.
	+ **Salt Transmutation** - Jack was able to transform a human into a pile of salt.
	+ **Soul Manipulation** - The raw energy of Jack's soul fully magnified was capable of vaporizing multiple hellhounds into oblivion.
	+ **Spell Casting** - Jack has the ability to cast powerful spells such as the Necromantiorum from the *Book of the Damned*. However, the spell failed to work as Jack lacked Mary Winchester's body.
	+ **Terrakinesis** - When Jack got angry at Asmodeus for harming the Winchesters and Donatello, his anger caused the ground to shake for a moment. In *Jack in the Box*, Jack was able to open and close earth underneath a woman accused of being a fake health healer to swallow her up. While trying to break out of the Ma'lak Box, Jack caused the box and the bunker to shake violently. File:Jack's Power.gif
	+ **Telekinesis** - Jack was able to send out powerful blasts of telekinetic energy strong enough to knock two people unconscious at once. When Jack did this, visible waves of energy emanated out of him. In a moment of pain, Jack accidentally threw a tattoo artist across a room. This happened without the visible waves of energy, indicating that Jack can use both forms of telekinesis. In order to save Sam's life, Jack blasted Buddy across a room with a telekinetic blast emanating from his hand while deflecting a bullet just by looking at it. Following this, Jack gained control of his telekinesis, using it to levitate a pencil and creating a small shockwave to knock Sam, Dean, and Castiel to the ground. However, when Jack attempted to use it to help against Dave Mather, he accidentally caught a security guard in the blast as well and killed him. When Jack uses his ability to produce a blast or shock wave his eyes glow gold but not when he used it in a more controlled manner like when he lifted the pencil. When confronted by two hostile angels, Jack was able to hit one with a telekinetic blast so hard she went flying through a glass window and then a brick wall. He was also able to force another angel to stab himself with his own angel blade, and later when using his telekinesis on Zachariah, lifted him into the air and showed the ability to in inflict immense pain on him. Jack's telekinesis is so powerful that he was able to blast the archangel Michael right off his feet, and did so without any visible effort. After his powers were restored, Jack was able to twirl an angel blade through the air with ease, but his carelessness caused him to accidentally stab Stacy with it. After Lucifer emerged from the Empty, Jack flung him back through the portal with just a wave of his hand.
	+ **Telepathy** - Jack showed the ability to telepathically call out to Castiel who could hear Jack even in the Empty. Even the Shadow was surprised how could something wake Castiel in his domain. Later, by touching his hands to Derek Swan's head, Jack was able to see everything that Derek saw with his powers. However, using this power on Derek caused the veins in his face to glow. Jack later used this ability, in the same way, to show the Winchesters and Kaia Nieves what Derek had seen of the alternate universe and their mother. After telepathically connecting to Kaia, who was dream walking at the time, Jack displayed a level of control over her vision, as he guided her from the Bad Place to Apocalypse World. He is so powerful that only a sufficiently powerful dreamwalker can hold this connection with him as the only known dreamwalker capable of holding this connection is Kaia, while Derek visibly struggled to and could not hold the connection for very long, making Jack have to break the connection in order to avoid seriously hurting him. Jack also has the ability to hear "angel radio" which causes him debilitating pain for unknown reasons. Additionally, when Sam prayed to him, Jack was able to hear Sam's prayers like an angel would have. In order to find out about Kaia's state, Jack used this to tap into Dark Kaia's mind and see Kaia through their connection. The Winchesters later state that Jack dreamwalked through Dark Kaia when he did this.
		- **Sedation** - Like an angel, Jack can put a person to sleep with just a touch.
		- **Precognition** - Jack, from the womb was able to see a vision of the confrontation between Castiel and Dagon at the Heavenly Portal, which he was able to share with Kelly.
		- **Mind Control** - Jack was able to make Lucifer tell him the truth against his own will. By simply saying "stop lying", Jack was able to make the entire planet tell the truth against their will.
		- **Empathy** - Jack was able to sense the pain of Sylvia in *Gimme Shelter* while confronting her.
	+ **Teleportation** - Jack displayed the ability to teleport after being upset by a conversation and wanting to be away from it. He was later able to use this ability to leave the Men of Letters bunker on purpose. When he teleports, Jack is shown to have the sound of wings flapping like an angel. Lucifer said he and Jack can go anywhere in the Universe.
		- **Apporting** - By putting his hand on Rowena he managed to send her back to her flat and telekinetically fling her against her desk without being there, a feat that has never been seen before. In *Jack in the Box* Jack managed to effortlessly teleport fifteen people to heaven with ease.
	+ **Super Stamina** - Jack once stated that he does not sleep a lot, but unlike an Angel, he still requires sleep. Lucifer once attempted to get Jack to go to space with him in an attempt to keep his deal with Michael from getting exposed; implying that Jack may not need oxygen.
	+ **Super Strength** - Jack wields enormous levels of superhuman strength that is clearly far above any Nephilim before him. While empowering Castiel, Jack enhanced his strength to the point of effortlessly restraining Dagon one-handed. After being born, Jack displayed sufficient strength to easily rip off the doorknob of a door that was triple-locked without even realizing it. In physical combat, Jack has been shown to effortlessly throw opponents around, and at one point he effortlessly knocked Castiel, a powerful Seraphim, to the floor with enough force to incapacitate him for a few moments and almost strangled a young man to death in less than a minute with one hand while enraged. Even while suppressing his powers to hide from God, Jack was still able to overpower a Grigori whom he took by surprise, as well as to rip out his heart, though another Grigori, who was prepared for him, was able to overpower him.
	+ **Supernatural Concealment** - When Jack does not want to be found, his powers are subconsciously concealing him from other beings which was shown by the fact that Asmodeus, Lucifer and everyone else who were looking for him were incapable of tracking his whereabouts. A demon stated that Hell had exhausted all its resources in an attempt to find him. This is notable considering how his immense power usually makes him very easy to locate. God was able to easily locate Jack in order to send Dean to kill him. Later on, Jack had to stay hidden in The Empty in order for God not to locate him.
	+ **Life Force Draining** - Jack is capable of draining a being of their life force. At the request of Castiel, Jack was able to draw most of the Seraphim's life force out of him by placing his hand on Castiel's head and concentrating, though Jack funneled the life force into a flask so that he could restore it later.
* **Immortality** - When Jack was dying after losing his grace, he claimed he would have lived forever if he still had it. Alternate Michael came to the same conclusion, claiming that Jack would "know time that makes mountains, that wipes out species" alongside Michael. Castiel also stated in time that he and Jack will have to watch the Winchesters die as they continue to live on.
	+ **Nigh-Invulnerability** - As the Nephilim Spawn of the second strongest archangel in creation, Jack possesses complete invulnerability to almost any harm. Unlike the other Nephilim, Jack is completely invulnerable against an angel blade as being stabbed in the heart with one by Miriam had no effect on him. Jack had stabbed himself in the chest several times with a butcher knife and did not die while such damage would kill any ordinary human. However, Jack can still feel pain, as shown when he flinched and reflexively threw a tattoo artist because of the pain from the needle, and can also be knocked out and injured by blunt force trauma to the head as any ordinary human, albeit this is usually when he is caught off guard or already in a state of shock. After he was flicked across a room by Michael, even while his powers were significantly weakened he was shown to recover quicker than any regular human would have. Even Zachariah, a powerful angel whose powers weren't affected by the warding was unable to recover as quickly as he did. The Suicide Bomb Sigil Kevin Tran used also had no effect on him whereas everyone else in the room were killed, besides Mary Winchester who Jack protected from the spell with his wings. Additionally, when shot twice by Dean to get his attention, Jack suffered no visible harm and was shocked more than anything by the action and later, when met with a sonic scream from an enraged Lucifer, while it made Sam and Dean cover their ears in pain and the Seraph Castiel feel discomfort, Jack was completely unaffected. While suppressing his powers to hide from God, Jack is more vulnerable at suffering injuries from an angel sword and cuts from a razor. However, even in this state, Jack stated that his captor couldn't kill him which the Grigori acknowledged. However, God was capable of easily killing Jack with just a snap of his finger and the equalizer, a gun created by God and which has the ability to harm God, was made specifically to kill Jack. After absorbing the power emitted from Michael fighting Lucifer and killing him and God killing Michael and beating Sam and Dean, however, Jack became completely unaffected by God's power, unfazed when God tried to smite him.
	+ **Immunity** - Despite his angelic heritage, Jack is immune to angel banishing sigil, a weakness that even Lucifer was affected by. However, the sigils do have an unseen effect on him, causing him pain and making golden marks appear briefly on his veins. He is also immune to most angel warding though being inside a building with very powerful warding can dampen his abilities, as seen when he was in Michael's fortress, he could do nothing with his powers. However, he was capable of thermokinetically melting the bars in the window of Michael's fortress due to the warding being somewhat weaker there. Jack also displayed an immunity to a Ma'lak Box, a specially warded coffin designed to contain anything for eternity, even an archangel. After absorbing enough power from Michael, Lucifer and God, Jack became immune to God's attempts to smite him, which left the former in shock.
	+ **Regeneration** - He was able to easily remove an angel blade from his chest and the wound quickly healed in seconds. After getting two tattoos, both healed in seconds to the point that there was no sign that they had ever existed. After Jack stabbed himself several times in the chest with a butcher knife, his wounds healed in mere moments.
* **Inherent Omniscience** **(possibly)** - According to Asmodeus, Jack is full of timeless knowledge. Even before he was born, Jack was already able to comprehend his pregnant mother's suicide attempt and use his powers to resurrect her, as well understand and remember some conversations that Castiel had with Kelly Kline while Jack was still in her uterus. Moments after he was born, Jack already had some basic knowledge like how to talk, walk, use some of his powers (like how he used his powers to grow up fast), etc. However, from that point forward, he only exhibited human-like awareness. Despite this, however, it seems that he does have some inherent omniscience that he cannot access directly yet, as his conscience, manifested as Lucifer, was aware of things that Jack refused to acknowledge to be true, as it knew that Jack's resurrection spell won't work and that he can't feel anything anymore, both which proved to be right. Likewise the manifestation of Jack's subconcious easily recognized that Sam and Dean were planning to trap him in the Ma'lak Box and never wanted to let him out and that they were also lying about coming up with a way to fix him.
* **Absorption** - After Jack survived the explosion when he became a "metaphysical supernova" he was turned into sort of a power vacuum. He gained the ability to passively absorb any energy that comes into contact with him, even the life energy from plants. While Lucifer and Michael were fighting Jack had been absorbing the energy that came off from them, including the energies released from the two archangels deaths. When he absorbed enough power he became unstoppable, immune to even God’s attempts to smite him. Once he gained enough power, he was able to extract and absorb God's power and make it his own, rendering God permanently powerless.

### God/Darkness Abilities

In *Inherit the Earth*, Jack absorbs all the power of God and The Darkness, who was merged with God and becomes the new God. Thus, Jack now has his and every power that God and Amara once possessed.

* **Nigh-Omnipotence** - After absorbing God’s power and Amara, Jack became fully omnipotent, and the most powerful entity in all of existence, capable of doing practically anything he wished.
	+ **Photokinesis** - When Jack became the new God, his whole body emitted golden light.
	+ **Healing** - After becoming the new God, Jack was able to heal Sam and Dean's injuries with a snap of his fingers.
	+ **Resurrection** - Just by concentrating, Jack was able to resurrect everyone and everything that God had erased from existence. Jack was also apparently able to resurrect Castiel from the Empty as Bobby Singer stated that Castiel helped Jack reshape Heaven into a much better place.
	+ **Restoration** - Jack was able to restore the Multiverse that God had previously destroyed. He is also possibly the one who restored the Colt which was seemingly damaged beyond repair by Dagon.
	+ **Reality Warping** - After resurrecting everyone and everything, Jack altered reality, making everything as if it never happened to those he brought back. As revealed by Bobby Singer, Jack tore down the walls separating the souls, ended their eternal memory loops and allowed them to coexist instead.
	+ **Teleportation** - After saying goodbye to the Winchesters, he teleported away. Jack can now travel across the entire multiverse on his own without opening a rift.
		- **Apporting** - After Dean Winchester said goodbye to his alternate parents, Jack teleported Dean, Bobby Singer, the Impala and himself back to their universe.
* **Nigh-Omniscience** - Like God, Jack is now effectively omniscient, also having all the knowledge of both God and The Darkness.
* **Omnipresence** - Jack stated he's now "everywhere", in every drop of falling rain, every speck of dust that the wind blows, everywhere in existence.

### Other Abilities

When Jack's Nephilim powers from his grace were extracted and absorbed by Lucifer, he was left powerless. However, he stills possesses a degree of moderate hunting skills and intelligence that help him stay somewhat useful. Despite his powers not returning to him as of yet, Jack was able to identify that he was in Heaven after noticing something was amiss. Naomi remarked that his perception to tell the difference most likely came from his angel side.
Even without his powers, Jack remained undetected from the powers of Noah Ophis, with Dean stating he was apparently close enough to pass for an angel. However, Ophis later stated he could see him after he confronted him. After a ritual to resurrect him and cure his condition which used Enochian magic that draws power from the soul, Jack was capable of tapping into this magic to use at least a portion of his abilities, however doing so burns off a piece of his soul each time. Now that he has absorbed Michael's grace to replenish his grace, he is no longer plagued by this weakness.

* **Proficient Hunting Skills** - Jack has learned a level of hunting skills from his time with the Winchesters, an example being that he has learned how to research for cases which he stated was from watching them do it themselves. Before the events of *The Bad Place*, he was able to research lore to learn about dreamwalkers and their ability to see into other realities, which is notable what with the lore on Dreamwalkers being inconsistent. He has proven to be an asset on hunts in *The Big Empty*, *Tombstone* and *Let the Good Times Roll*, finding a vital clue to the ghoul's identity in *Tombstone* without even relying on his powers. After Jack saves Lora without his powers, Castiel states that he has the mind and heart of a hunter even if he doesn't have the skills yet. Working with Dean, they were both able to successfully kill the zombie Vance together, but were not able to capture the necromancer Harper Sayles. After months of training by the Winchesters and Castiel, Jack became a proficient hunter in his own right even without his powers, catching the Gorgon Noah Ophis by surprise and killing him with a machete. After his resurrection, Jack went about hunting the remaining Grigori. He easily killed most of them before being captured by the last one. In *Gimme Shelter*, Jack and Castiel made an effective hunting team even without the presence of the Winchesters, although Jack makes the mistake of showing his FBI badge upside down.
* **Skilled Hand-to-Hand Combatant** - Alternate Bobby Singer taught Jack some basic boxing techniques. He was also able to tackle Garth off of Sam and restrain him for a time. However he lacks proper training like Sam and Dean and similar to Crowley, mainly uses his powers to give him the edge in a fight.
* **Intelligence** - Despite having quite a naïve personality, Jack has proven himself to be very intelligent on occasions. When a group of angels were pursuing him the Winchesters into the Sunstar Line cargo ship, Jack predicted that the angels would use angel radio on him as soon as they got to him, due to angels using it on him before. He easily figured out how the witch, Broomhilda's magic was killing Lora, something even Castiel and Jules couldn't uncover though Lora had told him the story of her captivity and not Castiel and Jules. He has been able to figure things out not only through intellectual perception but also emotional perception as well. When killing Michael, he was smart enough to absorb his grace to restore his own powers and save his own life.
	+ **Intuition** - Jack has shown himself to be quite intuitive. From the womb, he was able to instinctively tell that Castiel could be trusted after feeling him touch Jack's kicks. Jack even stated that he remembers feeling safe at that very time.
	+ **Manipulation** - He was able to successfully manipulate Harper Sayles' zombie boyfriend Vance into believing he wanted to be with her, so that Vance would get jealous and come out so Dean could bind him. He also managed to goad Dean and Castiel, who have both had experience with people manipulating them over the years, into believing that his condition was just a regular cough for some time, with Dean only finding out the truth when Jack bled and collapsed in front of him.
* **Adaptability** - Jack has shown himself to be highly adaptable to certain situations.
* **Enochian Magic** - With the loss of his grace, Jack's Nephilim body fell out of balance between his angel and human halves and started to deteriorate and eventually caused him to die. With the help of Castiel placing his soul back into his body from Heaven and the ritual taught to him by Lily Sunder, Jack was able to use Enochian magic to harness a small part of his soul to stabilize his condition to stay alive. With Enochian magic he was able to use a part of his soul to use his previous powers, but burned off pieces of his soul in the process each time. When killing Michael using this magic, Jack burned off his entire soul.
	+ **Angelic Exorcism** - Jack was able to pull Alternate Michael from Rowena's body.
	+ **Energy Blasts** - Jack was able to emit powerful blasts of energy able to knock Michael off of his feet.
	+ **Healing** - After Castiel was poisoned by Gorgon venom, Jack used the power of his soul to heal him when the anti-venom didn't work.
	+ **Invulnerability** - When Jack was blasted by Michael, he was knocked down at first but later withstood it like it was nothing.
	+ **Molecular Combustion** - When the Men of Letters bunker was attacked by a group of monsters, Jack was able to disintegrate them all at once, burning away another piece of his soul in the process.
	+ **Pyrokinesis** - After exorcising Michael from his vessel, Jack was able to burn away his essence leaving only Michael's grace behind for Jack to consume.
	+ **Regeneration** - After being resurrected, Jack used the Enochian magic to heal the condition that had killed him in the first place. After his condition reoccurred, Jack used the magic to heal himself again.
* After completing his quest, Jack turned into a metaphysical supernova bomb that had the capability to destroy God and the Darkness.

## Former Weaknesses

Jack Kline had some weaknesses as a Nephilim. In *Inherit the Earth*, he took away Chuck's power and consumed Amara. When Jack became the new God, he most likely lost all these weaknesses.

### Harming, Misleading or Trapping

* **Angel Radio** - Hearing the angels communicate over "angel radio" causes Jack debilitating pain for unknown reasons. However this only occurred shortly after his birth while his powers were not properly developed yet.
* **Archangel Blades** - An archangel blade is capable of harming Jack as seen when Lucifer cut Jack's throat and took his Grace. Mrs. Butters seemed to think that an archangel blade, even wielded by a regular human such as Dean, was capable of killing him, but this is unconfirmed.
* **Grace Extraction** - Before Jack's birth, Sam theorized that extracting his grace would leave him powerless and thus not a threat. In *Let the Good Times Roll*, Lucifer extracted most of Jack's grace with an archangel blade, leaving him completely powerless. Although it was revealed in *Stranger in a Strange Land* that Jack's Grace will slowly recharge, as of now, Jack has not regained any of his powers. In *Unhuman Nature*, its revealed that his grace is what holds his human and angel halves in balance and, when he lost it, his two halves come in conflict with each other, causing Jack's body to shut down progressively. The only way to revert that is for the Nephilim to recharge their grace. Even when given Archangel grace from his uncle, Jack's body did not accept it and his condition only worsen.
* **Ma'lak Box** - The Ma'lak Box was able to briefly contain Jack's powers, however he was able to explode the box and the surroundings with ease when he really tried.
* **Resurrecting Angel Ritual** - Making the ritual using Jack's blood made him feel great pain, but after asking Mary permission to use his powers he showed no pain even within the presence of the ritual.
* **Unexpected Mechanical Trauma** - While Jack has the superhuman endurance to shrug off bullets and knife wounds, Jack can be knocked unconscious or temporarily stunned with pain by physical forces when he is caught off-guard (or already in a state of shock). Sam had once knocked Jack unconscious by unexpectedly electrocuting him in the back with a taser in *Lost & Found*. Again in *The Big Empty*, the shapeshifter Buddy was able to knock Jack unconscious by hitting him in the head with a fireplace poker after catching him off guard. It should be noted that these occured before Jack developed his powers.
* **Very Heavy Angel Warding** - Jack's powers were severely weakened by the powerful warding in Michael's fortress, leaving him vulnerable to the powers of Michael and Zachariah. The warding was so much that when Jack attempted to use even some of his more easily controlled powers, he could do nothing. In a spot where the warding was weak, Jack was capable of using a weaker ability to melt metal bars. In *Jack in the Box* despite Jack's powers being weakened he managed to break out of the Ma'lak Box with ease.
* **Witchcraft** - While Rowena had contemplated fighting back against Jack using her magic, indicating that magic does have an effect on him, she admitted that she would not win a fight with him, indicating that although powerful magic could affect him, they do not have the ability to do any significant resistance. Using a potion made from Yarrow root and ground jaw bone in Jack's smoothies administered over time, Mrs. Butters was able to greatly weaken his abilities.
* **Mortality** - After having his grace extracted, Jack has become completely mortal and vulnerable to injury. A beating from Lucifer left his face heavily bruised and bleeding while stabbing himself in a suicide attempt caused Jack to bleed heavily before he was stopped. In *Stranger in a Strange Land*, Jack is stated to be as vulnerable as any human with his powers still having not returned. As seen in *The Scar*, he is now susceptible to sickness as he is suffering from an unknown illness and coughing up large amounts of blood. In *Optimism* things became much worse as after finishing a hunt he coughed up more blood and proceeded to bleed from his nose and collapse. It was later revealed in *Unhuman Nature* that this illness is the result of Jack's lack of grace, as his cells are attacking each other, causing his body to gradually break down without his grace, due to his human and angel halves needing to be stabilized by his grace. Though this was stabilized using Enochian magic and Jack's soul, it appeared to reoccur briefly later on. However, in *Ouroboros*, after absorbing Alternate Michael's grace and regaining his full Nephilim status, Jack regained his full capability of powers, including his original semi-immortality and invulnerability to harm.

### Killing

Due to Jack being one of the strongest beings in existence very few things can kill him.

* **God** - At his previous level during the time of his second death, Jack was no match for his grandfather. With a snap of his fingers, God was able to smite Jack, killing him. Following his resurrection, Jack was forced to hide until he could become stronger as God could easily kill Jack again if he became aware of Jack's return. After his survival of the initial explosion in the Empty and becoming a power vacuum that had absorbed enough energy, Jack became immune to God's and Amara's powers, best seen when God failed to smite him, Jack was then capable of absorbing all of God's powers.
* **The Equalizer** - A gun crafted by God himself that can kill him although it also cost the life of the user, if the user fatally shot him with it.
