Jacob Black

"Until your heart stops beating, Bella. I'll be here - fighting. Don't forget that you have options."

Jacob Black is a La Push shape-shifter or "werewolf", second in command of Sam Uley's Pack and later Alpha of his own. He is a Quileute Native American. In Twilight he is fifteen, and one year older in New Moon and Eclipse, at which age, he phases for the first time. He imprints on a hybrid baby named Renesmee Cullen, the daughter of Edward Cullen and Bella Swan. As with Quil Ateara and Claire, his love for Renesmee will not become romantic until she comes of age.

Early life
Jacob was born to Billy and Sarah Black. Sarah died in a car crash when he was very young, though Jacob never speaks of it. He has two older sisters, Rachel and Rebecca. Rebecca moved to Hawaii and eventually married, while Rachel, who had been off at college, returned later in Breaking Dawn and was imprinted on by Paul.

Twilight
Jacob has a small but very important role in Twilight. After Bella flirts with him (as a way to get information), he introduces the idea of Edward being a vampire by telling her the Quileute legends on the topic. After Bella and Edward began dating, Billy takes Jacob to Bella to advise her against it, without, however, telling her why. She already knows. He is later seen crashing Forks High's prom under his father's orders to reiterate the same warning.

On Stephenie Meyer's official website, Jacob was originally just a device to inform Bella about the "Cold Ones." However, both she and her editor liked Jacob so much that they decided to give him a larger role in the sequels to Twilight, making him a main character in New Moon, Eclipse, and Breaking Dawn.

In the movie adaptation, we see more of Jacob Black. He first shows up to bring Bella her new truck and give her tips on how to drive it. However, in the beach scene he doesn't actually tell her what Edward is. In turn, forcing her to do her own digging to get the answer she wants.

New Moon
"I know how you're unhappy a lot. And, maybe it doesn't help anything, but I wanted you to know that I'm always here. I won't ever let you down. I promise that you can always count on me."

- Jacob to Bella

Bella becomes very good friends with Jacob, after Edward leaves Forks in New Moon. Jacob helps her become somewhat happy and normal again, though she still misses Edward. New Moon reveals that Jacob is one of an ancient line of Quileute werewolves. They are the mortal enemies of all vampires, including the Cullen family. At first Jacob thinks all this is a bunch of superstition, and he becomes frightened and disturbed by the influence a young man on the reservation, Sam Uley, has on some of the Quileute youth. After Jacob goes through a sudden transformation to a werewolf, it is revealed that Sam, the pack's leader, was the first to make the transformation in several generations. He'd gone though his own hardships during the change, including a rather bloody incident with his fiancée, Emily Young. As werewolves are short-tempered, highly violent, and likely to explode into wolf form when angered, Jacob initially promises his pack he would stay away from Bella. He and his new friends patrol the forest, searching for vampires that have been killing hikers in the area. Jacob and the pack save Bella from the vampire Laurent (from Twilight), who was trying to kill her. Before the over-sized wolves chase him off, Laurent tells Bella that Victoria (also from Twilight) wants revenge on Edward for killing James, her mate.

Sometime later, Jacob unexpectedly shows up at Bella's bedroom window and apologizes for a recent fight and his avoidance of her. When she asks him what's happening with him, he claims that he can't tell her, but leaves her a clue to what he and the rest of Sam's group is. Bella remembers the stories Jacob told her (in Twilight), about the Quileutes being descended from wolves. The next day, she confirms that Jacob is a werewolf. She later confronts him, assuming his pack to be behind the recent murders in the forest. Jacob convinces her that their job is to protect humans from vampires, and they would never harm anyone. He also tells her that Laurent is dead, and together they figure out that a certain red-headed vampire terrorizing the werewolves and hikers in the forest is actually Victoria. But when Jacob calls his pack to give them the news, they are angered about it. Paul, one of the pack members, loses his temper, phases into his wolf form and tries to attack her. Jacob quickly phases in turn and viciously mauls Paul, chasing him into the woods. She and Charlie spend much of their time in La Push during her spring break. Jacob and Bella renew their friendship, and he tells her what it's like being a werewolf. Sometime later, still in grief over losing Edward, she goes cliff-diving and nearly drowns before Jacob pulls her out of the water.

Upon returning to the Blacks' home, Bella and Jacob learn that Charlie and Billy's friend Harry Clearwater has died of a heart attack; a quick succession of events later that evening and the next day pry Bella and Jacob apart. Jacob drives Bella home, only to discover that Alice has inexplicably turned up there; he recoils from her presence and flees to La Push to regroup. He returns to the Swans' home the next day to apologize to Bella; they nearly kiss when the phone interrupts them. When Jacob answers, he mistakes Edward's voice for Carlisle's, and, refusing to surrender much information, tells the caller that Chief Swan was attending a funeral. Having received cryptic information, Edward assumes the funeral is for Bella, thinking she killed herself. Grief-stricken, he depart in order to meet with the Volturi, and Bella and Alice rush to stop him. Jacob is hurt and disgusted by Bella's choice, Edward's return, and Bella's willingness to go back to him and become a vampire.

In the epilogue of New Moon, Jacob reminds Edward of the Quileute-Cullen treaty, which forbids the Cullen family from biting humans. This means that if a member of the Cullen family turned Bella into a vampire, the treaty would be broken and the werewolves could start a war. Jacob is upset by the whole conversation, though Bella manages to calm him down before she and Edward leave. However, when Bella turns to look at Jacob one last time, she sees he is suffering in heart-wrenching emotional pain.

Eclipse
The third installment of the series begins with Jacob still trying to keep a safe distance from Bella, who desperately tries to talk to him. He is not comfortable with the idea of Bella associating to a vampire, making him to almost lose control with anger.

The book starts with Bella receiving and reading the note from Jacob. He has a hard time expressing himself in it, as she reads through many unfinished sentences that end up being crossed out. The last comment in the note is not crossed out, and shows that even though he misses spending time with her, he is still angry about their situation.

Later on, his affection for Bella grows stronger. He's enraged that she will become a vampire after graduation, which is only a few weeks away. Bella feels bad that she's spending all her time with Edward and she sneaks off to visit him. He invites her to a Quileute council meeting, and she accepts. They spend the night together and listen to tribe legends, believed to be real by the Quileute. When Edward realizes that he has been overprotective, he encourages Bella to visit him on a regular basis. On one of the later visits, Jacob tells Bella he loves her, and kisses her, thinking she loves him back. Bella, outraged by this, punches him in the jaw and breaks her hand. Jacob brings Bella home and Edward threatens him that if he ever kisses Bella without her consent again, he'll break his jaw for her. But Edward also claims that he would allow it to happen if she wanted to kiss him.

A while later, at a graduation party held at the Cullens' house that Jacob decides to attend, he gives her a charm bracelet with a carving of a wolf on it as a graduation present. While there he learns that Victoria has amassed a newborn vampire army to attack Bella. Jacob and the pack eagerly agrees on joining forces with the Cullens and learning how to fight these vampires. Their original plan was to have Seth Clearwater watch over Bella in a remote mountain place while the Cullens and the rest of the werewolf pack fought off the vampires. Bella, however, wanted Edward with her when she stayed in the mountains, and asked Edward. Edward agreed as long as Jacob would carry her to the place in the mountains so that her scent would be lost. They followed through with the plan, and Jacob carried Bella to the mountain hideaway. While waiting for the battle to be over, Edward, Bella, and Jacob set up camp. A blizzard blows through the camp, and Bella begins to freeze. Jacob comes in the tent and stays in Bella's sleeping bag to warm her up with his abnormal body heat, much to Edward's chagrin.

During the night, Jacob asks Edward about his relationship with Bella and what it felt like to lose her. They talk and temporarily set aside their hatred for each other.

In the morning, Bella wakes up and Jacob leaves the tent. Bella and Edward then start discussing their marriage plans. Jacob overhears their conversation and runs away, upset. Upon Bella's request, Edward brings him back and leaves them alone to talk. As they talk, Jacob tells Bella that he's going to kill himself because she doesn't love him. Bella begs him not to and offers to kiss him if he promises to come back, and Jacob agrees. At first Bella is hesitant and starts to resist, but she soon finds herself kissing him back passionately and realizes that she is in love with Jacob after all. Jacob then leaves to battle, promising that he will try and not get himself killed, but gets injured trying to save Leah Clearwater from a newborn vampire. The newborn mangled all the bones on the right side of Jacob, before being destroyed by Sam. Carlisle patches him up and a worried Bella visits him. Jacob is shocked to hear that Edward didn't get angry at Bella for kissing him. They talk and she tells him that, although she loves Jacob deeply, she still has chosen Edward. While heartbroken over her choice, Jacob doesn't show it, and reluctantly agrees to stop trying to separate them. Jacob reminds Bella that he will always be there for her whenever she needs him.

The epilogue is written from Jacob's point of view. Jacob and Leah are sitting at the edge of a cliff, with Jacob thinking about how difficult it will be when Bella is turned into a vampire. Leah tells him to get over her, and Jacob angrily tells Leah to leave him alone. At home, he finds that Edward has sent him an invitation to the wedding. Enclosed there is a note saying that he is not obliged to attend, but that, if Edward was in Jacob's shoes, he would want a choice. Edward thanks Jacob for everything. Unable to endure his human emotions any longer, he phases into a wolf, and runs away. Jacob runs as fast as his legs can carry him. The rest of the wolves try to talk to him, but Sam tells them to leave Jacob alone.

Breaking Dawn
In Breaking Dawn, Jacob is mentioned to have been gone for almost two months now, and is trying to live the rest of his life as a wolf so he doesn't have to deal with the pain he is in. Jacob is first seen at Bella's wedding, that he decided to attend despite his pain. He apologizes to Bella and tells her that he only wants her to be happy. However, he becomes violent towards Edward when he finds out about their plans to make love while Bella is still human, and has to be restrained by Seth and Sam. During Bella and Edward's honeymoon, Jacob, rage-filled, imagines the different outcomes of the honeymoon.

When Bella finally returns from the honeymoon, Jacob believes she was turned and demands the pack attack the Cullens. Sam refuses to do so, and Jacob goes on a solo mission, leaving his own home in the process. He finds out that she is pregnant, and sees that she is bruised where her child has kicked. He talks with Edward, who doesn't want the baby because it is killing Bella, but cannot do anything because Rosalie Hale guards Bella, upon Bella's request. Rosalie's choice influences Emmett, Esme and Carlisle and so Edward cannot force Bella to have an abortion. Desperate, Edward asks Jacob to offer Bella to get pregnant with him, resulting in a much healthier pregnancy than the current one. Jacob is sickened but tempted, and agrees to try to persuade Bella to abort. He also promises Edward that he'll kill him if Bella dies.

Jacob informs Sam and of Bella's pregnancy. The pack plan on killing Bella and the baby because they see the unborn baby as a threat, which is however protected by the Cullens. Jacob still loves Bella, and rebels against Sam's authority as Alpha. He embraces his Alpha heritage and breaks away from the pack. Seth and Leah Clearwater join him patrolling the Cullens' territory, and preventing Sam's pack from attacking.

While running patrols, Leah requests to stay in Jacob's pack after Renesmee's birth. Though taken back by the idea, Jacob agrees to think about it. Leah admits to Jacob that she understands Rosalie and Bella, and that, if their positions were switched around, they would do the same for each other. Jacob is enraged by this and is lead into an awkward conversation about Leah's being menopausal and her love for Sam. Jacob ends the conversation to check up on Bella.

A few days later, Edward hears the baby's mind for the first time, and he loves the unborn baby as it already loves Bella, leaving Jacob feeling betrayed. Edward hears this and gives the keys of his Aston Martin Vanquish to Jacob, so that Jacob might get away from them. Jacob desperately drives out to look for his soul mate, someone who he may imprint on, so that he would forget his love for Bella. His search ends up fruitless.

Jacob comes back and learns that the baby has broken yet more of Bella's bones. Edward asks Jacob, as heir to the chief, Ephraim Black, for permission to change her into a vampire after the birth of the child. Feeling empty inside, Jacob agrees.

After Bella gives birth to a girl she names Renesmee, Bella appears to "die" after Edward bites her to turn her into a vampire. Jacob intends to kill Renesmee, but imprints on her when he sees her. He nicknames her Nessie, because her real name is a mouthful, and this irritates Bella, since it refers to the Loch Ness Monster and catches on. Jacob is extremely close to Renesmee, goes hunting with her, and for Christmas he braids her a bracelet that is the Quileute version of a promise ring. Jacob has a strong desire to protect her and to keep her happy and safe. It is likely that his feelings will eventually turn into romantic and sexual interests when she is older. It is hard for him to be separated from her, so he visits every day and almost never leaves the Cullen house. However, he states that once Renesmee's growing slows down, he will go back to school. Finally, Sam's pack stops trying to attack the Cullens, since the most important of the werewolf laws that one cannot kill the object of another wolf's imprinting, due to the damage it would cause to the wolf in question. It is also stated that Jacob's close friends, Quil and Embry, who stayed with Sam when Jacob went his separate way, also have joined Jacob's pack after Renesmee's birth.

For the Volturi arrival, Bella plans for Jacob to run away with Renesmee to Rio de Janeiro, so that they may be saved from the upcoming slaughter. She has passports forged for the two of them, with Jacob as Jacob Wolfe, and Renesmee as Vanessa Wolfe. When the Volturi shamefully and regretfully leave, Bella is overjoyed and calls Renesmee, "Nessie." At the end of Breaking Dawn, he, along with other wolves, hear from Edward that they are not really werewolves, but are rather shape-shifter. After the Volturi's "trial," Jacob jokes that life will be "boring now," which Edward remarks that he fervently hopes so.

Physical appearance
At 7', Jacob is the tallest character in the series, towering over Alice by nearly three feet and describing her as about the size of one of his arms. Bella notes that he would surely hit his head upon the beams of her new cottage. He also has a toned and thick muscular body, similar to that of a serious bodybuilder, though balanced by his tremendous height so he doesn't look out of proportion. In New Moon, upon discovering his werewolf powers and joining the Quileute pack, he crops his long black hair short. Later he grows it out to chin length in Eclipse because he thinks Bella prefers it longer. He tends to wear only cut-off style jeans or sweatpants, since they get ruined when he phases into a wolf. In Breaking Dawn he cuts his hair short again.



Wolf form
As a wolf, Jacob is about 10' in length, has russet brown fur, dark intelligent eyes, and is very swift. He is also the second fastest and the second largest in the pack. He later grows to be the largest and strongest, but Leah Clearwater is still faster than him. Sam acknowledges him as the pack's strongest fighter. Bella is still amazed that Jacob did not take the role of Alpha in Sam's pack.

Personality and traits
Jacob's personality changes throughout the books as he matures. In Twilight, he seems very friendly though shy and slightly sheepish around Bella, easily succumbing to her flirtations and worrying about how the Quileute legends will affect her perception of him. However, in New Moon Jacob goes from being his old, happy self to being sullen and temperamental. This is because he is has now phased and is experiencing life in wolf form. In Eclipse, he becomes a lot more confident that Bella is really for him - so much so that he makes her realize that she does love him after all. He also seems to be somewhat rebellious, since he encourages Bella to sneak out to visit him and they ditch school so they could spend some time alone, even though just as friends. In Breaking Dawn, his personality changes yet again, as he feels like Bella is going to die. He is ready to kill her baby daughter, Renesmee, until he imprints on her. After this and Bella's successful transformation into a vampire, he returns to his cheerful personality.

Wolf abilities

 * Phasing - Can phase in and out of wolf form. With practice and skill, one can morph faster and with more efficiency, with Jacob being the one exception, being able to phase in mid-jump, while it takes the rest of the pack several seconds to phase.


 * Regeneration - As a wolf, he has a powerful regenerative healing factor. This allows his body to heal at an abnormal rate, faster than any human body can. The extent of this regeneration is very powerful, to the point that Jacob comments that even a bullet through his temple wouldn't be enough to kill him. Small cuts and minor injuries heal within seconds while larger, more damaging injuries, such as broken bones and blood loss, seem to heal within minutes.


 * Telepathy - Only works within the pack, and when in wolf form. They can speak with each other telepathically and hear each other's thoughts. Though this is more than useful while hunting and tracking, there is no privacy left in the pack because of this ability. It can be described as both a gift and a burden. Their thoughts are open even when they tried to hide them. After Jacob formed a pack of his own, he is able to communicate those within his pack and Sam, the Alpha of his previous wolf pack, if he chooses to. Also, because his wolf mind is linked with his pack, Bella can protect him and his fellow wolves with her shield solely by shielding him.


 * Physically enhanced - Has super-strength in both wolf and human form. This has been displayed numerous times, as how Jacob was able to carry Bella 9 miles through a thick forest with ease, taking less than half an hour. In wolf form, they are also exceptionally fast, running at a top speed of about 80 to 90 miles per hour. In human form they seem to have an average speed of about 30 to 40 miles per hour, about half the speed of vampires, and can lift an average of about 500 to 600 pounds. Before phasing, the human form will build up their muscles naturally and will be ready for the first time they phase. It can be speculated that werewolves are actually stronger than vampires due to the fact werewolves can build up their muscles, strength and endurance. Jacob is known as the physically strongest in both packs, though not as fast as Leah.


 * Increased durability - Werewolves have a high durability rate, most famously seen when Bella struck Jacob in the jaw with all of her strength, and ended up badly breaking her hand while Jacob, who wasn't even remotely hurt, couldn't tell that she was trying to hurt him until she started screaming. Jacob also mentioned in Breaking Dawn that it would take a large truck, moving at high speed to break his bones.


 * Delayed aging - They cannot start aging until a solid period of time without phasing goes by. It is unknown the exact length of time, only it would be very difficult because phasing is instinctual, along with the fact that vampires often come through Washington and the werewolves are needed whenever vampires are close.


 * High body temperature - Werewolves have a constant body temperature of about 110° degrees to withstand severe cold weather. This high body heat also allows them to survive in very hot weather, making it hard for their bodies to overheat. This high body temperature is very useful in combat, as it makes it extremely hard for vampires to harm them because they are extremely sensitive to heat. In Breaking Dawn, after Bella becomes a vampire, she describes Jacob's skin as like touching an open fire and unbearable to touch. This temperature also prevents frequent illness, by killing any potential pathogens they come into contact with before they can become ill.


 * Alpha voice - As the Alpha of his pack, the wolf can force his followers to obey his orders whether they refuse or not. Jacob never uses his voice to force his teammates, though he has the power and it is even stronger than Sam's voice.

Family
Jacob's father is Billy Black, his mother is Sarah Black, and he has twin sisters, Rachel and Rebecca. Billy and Jacob seem to be pretty close as they have lived alone together for a fairly long time. On the other hand, Rachel, Rebecca, and Jacob are not as close as the twins live out of town and rarely see their brother. It has been reported that Jacob's mother had died gruesomely in a car crash, her coffin having been nailed shut at the funeral.



Bella Swan
"I'd forgotten how much I really liked Jacob Black."

Jacob claims in Twilight that he had a crush on Bella, but didn't act on it since she was already with Edward. In New Moon, he spends more time with Bella, and his crush turns into love. He is romantically attracted to her, although she only sees him as her best friend. As stated in Breaking Dawn, he has often imagined Bella nude. His feelings for her put him at odds with Edward. Jacob tells (or rather, shows) Bella how he feels in Eclipse by forcibly kissing her, to which she reacts by punching him in the jaw, only to end up with a broken hand. Jacob does everything he can to try to convince Bella she is in love with him, but she rejects him. Then later on in Eclipse, he threatens to kill himself if she doesn't kiss him, so she does. The kiss makes Bella realize that she has been lying to herself by saying that he was only her best friend, because she is in love with him too. She kisses him back, and both share a kiss that Seth Clearwater calls "nauseating to watch". When Edward finds out, he isn't angry, but Bella knows that she has to choose. She visits Jacob to tell him that although she loves him deeply, she has chosen Edward. Heartbroken, Jacob runs away from home and tries to live as a wolf to escape his pain.

Despite Bella's rejection of him, Jacob is still in love with her, and abandoned his former pack to protect her when she is pregnant with Renesmee. But he still is in constant pain because he failed to win her over. When Jacob imprints on Renesmee, however, his romantic feelings for Bella disappear, managing to put their issues behind and keep her as a best friend. Bella is relieved that, despite having become a powerful vampire, Jacob still sees her as Bella.

Renesmee Cullen
"My shaking jerked to a stop; heat flooded through me, stronger than before, but it was a new kind of heat - not a burning. It was glowing. Everything that made me who I was - my love for the dead girl upstairs, my love for my father, my loyalty to my new pack, the love for my other brothers, my hatred for my enemies, my home, my name, my self - disconnected from me in that second - snip, snip, snip - and floated up into space. I was not left drifting. A new string held me where I was. Not one string, but a million. Not strings, but steel cables. A million steel cables all tying me to one thing - to the very center of the universe. I could see that now - how the universe swirled around this one point. I'd never seen the symmetry of the universe before, but now it was plain. The gravity of the earth no longer tied me to the place where I stood. It was the baby girl in the blonde vampire's arms that held me here now. Renesmee"

- Jacob imprinting on Renesmee

Jacob imprints on Renesmee Cullen, Bella and Edward Cullen's daughter.

In Breaking Dawn, when Bella became pregnant with Renesmee, Jacob was repulsed because he saw her as he saw Edward: a monster. Jacob made his hatred for the baby clear on multiple occasions, including when he became angry at Bella for saying the baby reminded her of him. Bella nearly died giving birth to the baby, who she named Renesmee. During Bella's transformation into a vampire, Jacob believed that she had died, and went to kill Renesmee. When Jacob saw Renesmee for the first time, he imprinted on her. He then realized why he was so pulled toward Bella during her pregnancy, and why Bella was so pulled toward Jacob: because Renesmee was a significant (due to the similarities between her and her mother as a human) part of Bella.

While Renesmee is a child, he only feels the need to protect her and keep her happy; nothing else is more important. As she grows up, Jacob will feel attracted towards her as part of the imprinting. It is implied that Renesmee will "accept" Jacob as her mate when she is old enough, since she loves him very much. Bella isn't very happy about this at first, and at one point attacks him, an effect of her temper as a newborn vampire. As time passes by, she comes to accept it later on when she realizes that it's not her choice, that they were made for each other.

Jacob thinks of Renesmee as "more special" than all of them put together and that she's "the most wonderful person in the world."

Because he finds it hard to be away from her, he visits the Cullens every day to play with her, though he would argue with Rosalie about whose turn it is to feed her. He is the one who nicknames her "Nessie," saying to Bella that her full name is a mouthful. When Renesmee was misunderstood by a vampire named Irina to be an immortal child and reported her to the Volturi, Bella secretly arranges ID certificates, a driving license and passports for Renesmee and Jacob, knowing that he will definitely protect her if the Volturi come looking for them. She also would have sent them to Rio, hoping Alice would be able to find them. On Christmas Day, Jacob gives Renesmee a hand-braided bracelet which is the Quileute's version of a promise ring as Christmas gift.



Edward Cullen
"If you weren't planning on sucking the life out of the girl I love, I might... no. Not even then."

- Jacob to Edward

After completing his growth into a werewolf Jacob develops very severe antagonistic feelings towards Edward, to the point of very nearly killing him openly in front of Bella several times throughout the series. This is because werewolves and vampires are mortal enemies. This bitter hatred was also due to the fact that he developed romantic feelings for Bella during New Moon and vowed that he would not stop fighting for her until her heart stopped beating (she becomes a vampire). But later in Breaking Dawn he is rather neutral, becoming something remotely to friends with Edward when he was helping Edward with Renessmee's birth and Bella's survival during this giving of her daughter's birth as Edward respectfully asks him as the leader or Alpha Wolf of the La Push pack if turning Bella into a vampire was permitted.

Jacob eventually declares his feelings for Bella, having already been Edward's rival for her love. Despite this, Edward never feels any hatred towards Jacob, even when Jacob tricks Bella into kissing him and Bella realizes, after over a year of self denial, she has feelings for him as well. When Bella tells Jacob that she had chosen Edward, Jacob's hatred for Edward reaches its peak and runs away in his wolf form, ending the events of Eclipse.

In the events of Breaking Dawn, Jacob makes a surprise appearance at the wedding of Bella and Edward. Bella accidentally tells Jacob her honeymoon plans causing Jacob to loose it momentarily. His hatred for Edward slowly begins to fade when Bella becomes pregnant with Edward's child. While Jacob is furious that Edward has impregnated Bella with a baby that is killing her, they form an unlikely bond because of their mutual hatred for the "fetus." Jacob feels betrayed when an unborn Renesmee wins Edward over. After her birth, Jacob imprints on Renesmee. While Edward is annoyed by this, he understands that Jacob's imprinting is involuntary. Their relationship becomes much friendlier after this, though Edward is still annoyed with his connection to Renesmee. Jacob, as commented by Bella, begins to call Edward's name without a hint of sarcasm.

When the stand against the Volturi appears to turn into a fight, Bella gives him her daughter and Edward says goodbye to Jacob, referring to him as his "son" as Jacob imprinted on Edward's biological daughter Renesmee. The situation, however, doesn't turn violent, and by the end of book there is no longer any hostility between Edward and Jacob. Edward also expresses impression of Jacob for not having thought about Renesmee's maturity process even once after he found out about her approximate maturity completion. At the end of Breaking Dawn, Edward states he would like to see Jacob to compete with Nahuel for Renesmee because Nahuel took interest in Renesmee as them both being half-human/half-vampire hybrids.



Embry Call
Jacob and Embry and Quil have been best friends every since they were young. Since no one really knew anything about Embry's father other than he was a Quileute, some people suspect that he and Jacob may be related, although he thinks of Sam Uley as a more likely candidate.

When Embry starts skipping school in New Moon and following Sam around, Jacob and Quil remain in the dark about his transformation and grow hatred toward Sam for "brainwashing" their friend, blaming him for taking Embry away. After Jacob experienced the change, however, they go back to the way they were, but they also avoid Quil until he changes as well.

When Jacob leaves the pack to protect the Cullens from them, Embry is deeply upset with his decision and is prohibited by Sam from seeing him. A few months after Jacob started his own pack, Embry leaves Sam's pack to join his, along with Quil.



Quil Ateara
"Yeah, I miss you, too, bro."

- Jacob to Quil when they were in seperate packs.

Quil and Jacob and Embry have been best friends ever since they were young. When Embry experienced the "change," he started to avoid them, and Quil worried for his sake. And when Jacob started changing too, he grew terrified that he might be next, which he admitted to Bella. Jacob and Embry continued to avoid him, until Quil experiences the change himself and happily reunites with his friends, after he finally understands what is going on.

When Quil runs into Jake in Breaking Dawn, Jake tries to talk him into dating other girls before Claire, his imprinted one, comes of age, but he finds it difficult to cope and decides to dismiss the idea.

When Jacob first broke from the pack, Quil remains behind, as he is unsure whether or not he should join him. A month or two later, Quil finally breaks away from Sam's pack and join him, along with Embry.



Leah Clearwater
"Am I less annoying than Paul now?"

- Leah asks Jacob

Jacob did not originally get along with Leah, since she was always tormenting him and his pack with painful memories and thoughts about Sam, who dumped her after he imprinted on her cousin, Emily.

During the battle against Victoria's army of vampires, Leah attempts to prove her worth and tries to fight a vampire, but it catches her off guard and Jacob knocks her out of the way to save her, and the vampire jumps on him, breaking most of his bones. After Bella chose Edward over Jacob, she irritatingly tells him to get over her, in which he reacts very badly.

When Jacob runs on his own, Seth, Leah's little brother, runs with him. Two days later, Leah comes along in order to get away from Sam and look after her brother. During this time, they learn to cope with one another and even become good friends, although Leah is still very uncomfortable being around the Cullens.

After the tension between both packs is solved, Jacob makes Leah his Beta, i.e. "second-in-command." Although Jacob is the strongest wolf, Leah is the fastest.



Seth Clearwater
"I've been helpful, haven't I, Jake?"

- Seth asks Jacob

Seth is one of the youngest wolves of the Quileute tribe who has always viewed Jacob as his idol, and always follows his instructions.

When Jacob broke away from Sam's pack in Breaking Dawn, Seth is the first to run and join him, partly because he has befriended the Cullen family and wishes to help protect them. Jacob is initially very unhappy with his decision as he intends on going alone, and later Leah decides to join them to get away from Sam and look after Seth.

Edward comments that he has one of the "purest, kindest and sincerest minds" he's ever heard, and that Jacob is lucky to have him, to which he doesn't disagree.

When Bella attacks Jacob in blind rage after she turned into a vampire, Seth runs into the middle and take the blow into himself and subsequently breaks the bones on his shoulder.



Sam Uley
"Jacob? What have you done?"

- Sam on Jacob about using his Alpha voice.

The relationship between Jacob and Sam before they phased is unexplained, although they have known each other since childhood. When Jacob's friend Embry, and Jared and Paul, phased, Sam took care of them and made them part of his pack. The still unaware Jacob believed that Sam has somehow turned his friend into his "gang" and hated him for it. When he finally phased, however, he understood Sam's situation and their relationship turned friendly.

Their friendship is greatly damaged when Bella gets pregnant and Sam decides to make an unprovoked attack to prevent a potential threat and Jacob disagrees. Sam tries to force everyone using Alpha command, and Jacob breaks away from the pack by making himself a new Alpha. With Jacob, Seth, and Leah gone, Sam decides to play the situation by ear and make his decision later. After Jacob imprinted on Renesmee, Sam is forced to declare permanent peace with Jacob and the Cullens. Their friendship begins to re-establish after this.

Jacob means "supplanter." This could refer to how he took Edward's place in New Moon and tried to replace him completely throughout the saga. This is also the name of one of Stephenie Meyer's brothers.

Film portrayal
The role of Jacob was played by actor Taylor Lautner in the Twilight film. Lautner later reprised his role as Jacob in the sequels, New Moon and Eclipse. He has also been confirmed to return as Jacob in Breaking Dawn.

His role was considered to be recast after the success of Twilight, but Taylor eventually got it again. He mentioned that he spent hours working on his body to improve his muscles in order to prepare himself for the role in the sequels.

Trivia
In the original sequel to Twilight, Forever Dawn, Jacob and Bella are not close as Edward never left Bella. Despite this, Jacob still imprints on Renesmee Cullen -- though it is a few weeks later rather than immediately after her birth. Also, Jacob dies somewhere along the way in the book, though his death is not very significant because he was not made out to be a major character in Forever Dawn.
