"At first, Jacob hated the Cullens. He couldn't even say the word 'Cullen'. But now he really is a Cullen."
- ―Taylor Lautner on his character.
Jacob Black is a shape-shifter or "werewolf" of the Quileute tribe, former Beta of the Uley pack, Alpha of his own and part of the tribal council. In Twilight, he is fifteen years old, and in New Moon, he phases into a wolf for the first time at the age of sixteen. In Breaking Dawn, he imprints on the hybrid baby named Renesmee Cullen, the daughter of Edward Cullen and Bella Swan.
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. He forms a deep bond with Bella in the sequels, and tries to fight against Edward for her love, until she realizes that her love for Edward is stronger and chooses him over Jacob. Jacob subsequently imprints on Bella and Edward's daughter, Renesmee, thus freeing himself from his heartbreak and triangular issues with Bella and Edward.
Jacob marries Renesmee when she became the age she looks and became the father of Evan and Sarah Black. He is also the father-in-law of Damien Grant and Korrina Snow and the godfather-in-law of Lucien Summers as well as the godfather-in-law of Luna Snow. Jacob is the son-in-law of Edward and Bella, adoptive grandson-in-law of Carlisle and Esme Cullen, the adoptive nephew-in-law Emmett and Alice Cullen, Jasper and Rosalie Hale, Lucas Stone, Krystal Diamond, Tiffany Stewart and Jalen Long and the adoptive cousin-in-law of Lucina Stewart and Bryce Summers. His Life and Death counterpart is Julie Black.
He is portrayed by Taylor Lautner in the movie adaptations.

"It took awhile to convince Edward not to rip my head off."
- ―Jacob on his relationship with Renesmee
Years later after the confrontation with the Volturi, Jacob attends Renesmee’s sixth birthday party where her family and friends are. Jacob acts as a best friend to Renesmee. There, Jacob started developing romantic feelings for Renesmee. After the party, Jacob confessed his love for Renesmee and kissed her thinking she would feel the same because of imprinting. Renesmee however didn’t feel the same way, hurt by Jacob’s actions. The result of it caused Edward to nearly kill Jacob for telling Renesmee how he felt about her when she wasn’t ready but instead Jacob was punished by not seeing Renesmee for two weeks. Renesmee later came around having feelings for Jacob and the two have been together since then.
A New Life

Renesmee and Jacob.
"Some protector I am. If I've known about that night, I would have save Lucas and his family but how should I know?"
- ―Jacob
Two years later, Renesmee was with Jacob when they heard a cry in the woods and they came to see a boy, Lucas Stone, being attacked by a grizzly bears. Seeing that Lucas is in trouble, Jacob phases into a wolf and leads the bear away from Lucas and comes back in human form to see Renesmee helping Lucas up. She offers to take Lucas to Carlisle due to his arm being attacked by the bear. Jacob then noticed seeing some sort of substance around Lucas briefly and went to inform the pack about Lucas not sure if Lucas is considered dangerous. He returns to the Cullen house where the Cullens are discussing about Lucas as well seeing too that they were uncertain if Lucas is considered a threat since Edward, Alice and Jasper couldn’t use their gifts on him. However after hearing about how Lucas lost his family and has nowhere to go, Jacob agrees with the Cullens to allow him to stay at their place. Jacob then sees that Lucas is no threat after getting to know him seeing that Lucas knows about cars and making deals offering him a job as everyone else got to know Lucas and all agreed that Lucas pose no threat and decided to allow him to become part of the family. The next day, Jacob and Renesmee took Lucas to hang with the tribe at La Push while the Cullens sets up a surprise party for Lucas. However, Lucas was hit by a car after he pushed Renesmee out of harm and by the time she and Jacob hurriedly brought Lucas to Carlisle, he was reported 'dead' until Edward somehow heard Lucas's heartbeat but barely which made Jacob give permission to change Lucas. Three days later, Lucas wakes up from his transformation and joins the coven after being told about the world he lives in.

Jacob meeting Lucas.
Jacob then sees the strange substance around Lucas when he and Collin ended up fighting when Collin insulted Renesmee and the Cullens discover that Lucas has the gift to use his aura to protect himself from other gifts like the Cullens’. As they help Lucas train to use his gift, Edward informs Jacob that Lucas kissed Renesmee, leaving out the part where, causing Jacob to angrily chase after Lucas. In the middle of August, Renesmee was missing. The Cullens were trying to figure out what happened to her until Lucas saw people, despite being invisible because Lucas saw their auras, attempting to kill the Cullens and warned Edward warning everyone else as they survived. Jacob, Edward, Lucas and Emmett then caught May and Niall from outside calling the shots and find out that they work for Aro and the Volturi who are were the ones who kidnapped Renesmee and destroyed the Cullens. Jacob and the Cullens arrived to Volterra to save Renesmee only to see that she's 'states' that she wanted to join the Volturi. However thanks to Lucas, he was able to rescue Renesmee seeing that she was hypnotized by May and Niall’s sister Olivia. However, Aro refused to let the Cullens walk away and soon everyone minus Lucas was restrained by the guards. Edward soon found out that the Volturi were the ones that caused the death of Lucas's family causing Lucas to go on a rage taking down every guard and member in his way until he reached Aro. Carlisle and Renesmee stopped Lucas just in time and Aro reluctantly allowed the Cullens and Jacob to leave until Lucas's rage came back causing him to mysteriously go unconscious when vampires couldn't. After they returned to Forks, Lucas left the Cullens without giving any info since his aura blocks Edward and Alice's gifts except saying that he 'had to take care of something.' Fearing that he might be going back to the Volturi, everyone tried to convince Lucas to stay but he refused and left without another word. A week later, Lucas returned to Forks and explained that he went back to Lacey to see his friends before they go to college and visited his family's grave. Jacob, as well as the rest of the family, allows Lucas into the family without the need for permission.
The Other Half & A Reason To Smile

"Wow he really needs help."
- ―Jacob on Lucas
Jacob and the Cullens sees that Lucas is depressed and the reason for that is because he is the only one who hasn’t found a mate. He then hears that Lucas is in love with Krystal Diamond from school and Jacob is amused about what’s going on between the two and also happy for Lucas.
Jacob goes with Lucas along with Bella, Edward and Renesmee to watch Krystal at her volleyball game where he fell asleep the whole game. He wakes up to see it over where Lucas ask Krystal out on a date. When Lucas asked her out, Jacob was amused and laughs with Edward how Lucas handled it in the end. On Lucas and Krystal’s first date, Krystal finds out about the supernatural after witnessing Lucas feeding off a deer and Jacob gets to officially meet her.
One afternoon at his shop, Jacob along with the pack were chasing after a vampire that has been coming across their land lately until he suddenly disappeared in a flash. Jacob was able to follow his scent meeting up with Edward who tells him Krystal’s father Roark Diamond was killed by a vampire and another one is after her. The Cullens move Krystal into their home after talking to the principal to allow Carlisle and Esme to be Krystal’s guardian so that she doesn’t move to New York. Two weeks later, Renesmee invites Lucas and Krystal to join her and Jacob to hang with the pack at La Push. She also allows Krystal to invites her friends there where they were imprinted by the pack members: Leah and Nathan Dallas , Seth with Carly Jensen and Embry with Danielle Olsen thus leading them to know about the supernatural.
Afterwards, the Cullens and Jacob were trying to deal with the disappearances of many residence in Seattle when they suddenly see themselves on the floor with their place being destroyed and that half an hour has passed adding that Krystal is gone. After failing to find her, the Cullens received a visit from Nahuel that his half brother Jonathan, along with Miley Ray, Krystal's tormentor now a vampire by Jonathan, has Krystal. The reason why Jonathan is doing it is because he wants revenge against Lucas for killing Olivia, from the previous story where the Volturi told him leaving out that what Lucas did was unintentional, by killing Krystal so that Lucas will suffer the same way Jonathan has. The Cullens also find out that Miley sent an army of newborn vampires attacking the Cullens and then uses her mental sharp jabbing gift to knock them out. Then she finally erases their memories of the events that has happened.
The Cullens and Jacob are in Seattle where Jonathan and Miley were spotted. Jacob was with Renesmee when they were attacked by the newborn vampires and were in trouble due to the newborns going for Renesmee because of her blood from her half human trait until they were saved by Edward and Bella. They arrived at the abandoned factory with the rest of the Cullens where Lucas found Krystal and Jonathan where Jacob stops him from attacking Lucas and Krystal and he along with Edward, Emmett, Jasper and Bella, they ripped Jonathan’s body and burned him. After the Cullens destroyed Jonathan, and seeing that Krystal was on the verge of death from being tortured and fell landing on her head, Jacob gives Lucas permission to change Krystal into a vampire and he does so. Krystal wakes up from her transformation where she goes out for her first hunt and Krystal became part of the family.
A year later after high school graduation, Lucas proposed to Krystal and the Cullens celebrate the occasion.

The Cullens receives a visit from Tiffany Stewart, Lucas’s friend, who was brought in by Carlisle after her appointment giving the news that she is pregnant. According to Carlisle, Tiffany is carrying a half human half vampire hybrid and Edward sees in Tiffany’s mind that the father of her child is Joham, Nahuel’s father using human women to create a “super race” of hybrids. The Cullens told Tiffany about it revealing themselves as vampires as they help her with the pregnancy. Afterwards, Jacob informs the pack of the situation where Jacob has new members.

Four years later, Jacob and the Cullens visited Renée so that Renesmee can finally meet her since Renée is the only family Renesmee hasn’t met yet. After the trip, the Cullens were on a plane home until Benjamin caused a mishap with his gift causing a huge delay in Detroit, Michigan and with Alice’s visions unable to work, they are lost. While trying to find the airport back to Forks, they meet Zoran’s coven who all want Lucina and Renesmee for their blood.

After the Detroit coven cause Zoran’s coven, the Cullens noticed that Tiffany is missing remembering that she took off thinking the Detroit coven are part of Zoran’s so she uses herself as a distraction so Jalen Long goes off to find her.
While Jalen went off to find Tiffany, the Cullens and the Detroit coven hid themselves from Steve and Spike who knows about the existence of vampires. After those two were gone and the Cullens asked Mordecai for directions to the airport, Mordecai questions them and insults Renesmee and Lucina causing tension between the two covens and the Cullens left Mordecai and his friends. After the coven left to find their way home, Edward explains to them that the reason why Mordecai and the others resents humans because of how they were mistreated before they became vampires due to near death.
While finding their way to the airport and looking for Tiffany, the Cullens stumble across a house on fire with two kids inside.

Lucas’s action has earned the respect from Mordecai and his friends as they offered them to stay at their place. When they arrived, they found Tiffany kissing Jalen which causes tension between Jalen and Mordecai making Jalen go outside upset with Tiffany behind him. During that, Steve and Spike showed up and discovered Tiffany when Jalen ran back inside without knowing he left her behind.

That night, Tiffany didn't return and everyone minus Jalen can't find her and Mordecai urges the Cullens that they have to go now before their flight leaves. The next morning, the Cullens said goodbye to Mordecai after showing the way to the airport. When they were about to go forward, Lucas refuses to go without Tiffany convincing Jacob and everyone to go back and find her. However, before they could, they are stopped by Zoran’s coven and like before, Jacob struggles against Virgil even with Emmett’s help until Tiffany comes in and saves her family and destroys Zoran’s coven single-handily.

Have A Purpose

"I would have never thought that my life would go in that direction. I wouldn't have thought that one day, I became Alpha of my own pack, soon to get married to a half-human half-vampire who is pregnant with my child but that's what life is about. Life means fate and fate, well, fate was something I would never understand."
- ―Jacob
At the beginning of Have A Purpose, Jacob is present at Tiffany and Jalen’s wedding where he catches the garter tossed by Jalen, much to Edward’s horror. While Tiffany and Jalen were heading back from their honeymoon, Jacob was at work with Renesmee at his garage where he receives a newspaper of Jalen being on the run accusing of raping Elena Margaret when they were kids only that it was Jalen’s foster dad who committed it.
Later on after her family returned home from school, Jacob and Renesmee were on their way home when they came across Jemma, a girl with no scent, and brought her over to the Cullens where Jemma states to have no one so the Cullens allowed her to stay with them. One night, Jacob and Renesmee were at La Push and were about to head home when Alice called them that Lucina is out on her first date with Bryce Summers who fall for each other and are being harassed by Orion Stern and The Big Five so Renesmee and Jacob drove over to the restaurant Lucina and Bryce are in and Jacob comes in and stops Orion from making Bryce look bad sending him and his friends kicked out of the restaurant. Right afterwards, he introduces himself to Bryce before he and Renesmee left to go home leaving Lucina and Bryce alone. When Lucina came back from her first date with Bryce, the Cullens found out that Jemma disappeared. After searching for Jemma, all everyone could find was a scent Bella and Edward picked up and they hear from Alice that something is about to happen to the Volturi.

During prom night, Jacob goes with Renesmee as guests to dance but mostly because she and her family are there to keep an eye on Orion who is with Lucina as his date because Bryce broke up with her (due to Orion blackmailing Jalen to do so as he suspects something about the Cullens being different). Lucas, Edward and Alice soon found out what’s going on from Jalen after he gave Lucas his aura back and told Jacob and the family what’s going on and what to do while Jalen got Bryce and Lucina back together.

Evan Black is Jacob's vampire/human/shape shifter son.
After the Cullens moved to Minnesota and met the Walker family, a new pack was formed and Jacob made Evan the Alpha of the pack while Jacob became the council leader of the tribe.
Evan and Jacob have a good father son relationship similar to Jacob and his father Billy. Jacob shows his care for Evan such as sending him and Sarah with Lucien and Luna away for protection away from Skai as Evan shows the same when he heard that Skai has captured his father. When Korrina started growing up, Evan’s feelings changed due to imprinting and not wanting Evan to go through what Jacob did with Renesmee, Jacob advises Evan to wait until Korrina confesses to her feelings for Evan first. However, he regrets it seeing that Korrina was asked out by Randy before Evan but Evan assures him that it wasn’t his fault.
Evan has inherited his father’s ability to shape shift due to the Black bloodlines thus also inheriting his right as Alpha of the pack. Evan is the spitting image of Jacob with his appearance and most of his hair of black. Evan has shown to also inherited the gift of mind reading to members of his family only similar to how Jacob can only hear the thoughts of other members of the pack in wolf form. He also inherited Jacob’s love for cars and works with him at Walker Mechanics.

Jacob's daughter-in-law: Korrina Snow.
Korrina Snow is Jacob's daughter-in-law.

Jacob identified the imprinting between Evan and Korrina when he saw how Evan was staring at her. As Korrina got older, Jacob wanted Evan to avoid the same mistake he made with Renesmee by telling Evan to wait for Korrina to confess her feelings to him first which resulted Korrina agreeing to go out with Randy when she had no clue fully about the imprinting but knows Korrina will chose Evan in the end. In the epilogue of Long Live Life, Korrina marries Evan thus making her Jacob’s daughter-in-law.

Sarah Black is Jacob's vampier/human/shape shifter daughter.
Similar to Edward and Renesmee’s relationship, Jacob and Sarah have a bond of a stereotypical father daughter relationship where Jacob is very protective of Sarah such as not wanting her risking her life as a werewolf. Jacob also shows his concern for Sarah’s safety when he sent her and Evan with Lucien and Luna away for protection away from Skai. Sarah shows the same when he heard that Skai has captured her father. When Jacob heard that Sarah had imprinted on Damien, he was not okay with it but couldn’t stop it. Sarah went into deep depression when Damien told her to leave him alone believing she’s using him and it hurt Jacob from seeing her that way. He even stopped Sarah from running away while staying in wolf form to avoid going through the same thing he went through. He forbade Sarah and Damien from marrying so soon when they announced the engagement but gave up in the end.
Sarah has inherited her father's ability to shape shift due to the Black bloodlines. Sarah has inherited her father’s skin tone but lighter and most of his hair color.

Jacob’s disapprovals later turns to hatred when Sarah went into depression caused by Damien when he believed Sarah was using him as a joke when she now notices him and he told her to leave him alone even though Damien didn’t intend to hurt Sarah before he was told about the supernatural and Sarah’s imprinting on him. Despite that Damien now knows about the supernatural and understanding Sarah’s becoming interested in him now, Jacob still has a hard time accepting their relationship, even though he sees that Damien is a good person and would never hurt Sarah, especially the fact that Damien is now a vampire.
A month before graduation, Damien proposes to Sarah making them engaged. However, Jacob does not approves and while Damien isn’t bothered about it, Sarah agrees to wait until after college or until Jacob decides to give his blessings to them during that which happens halfway through college.
