"C'mon Edward. Just turn it off for one minute and fight fair."
―Emmett to Edward Cullen, on Edward's ability to read minds.[src]

Emmett Cullen, born Emmett Dale McCarty in 1915, is a vampire and member of the Olympic Coven. He is the husband of Rosalie Hale and the adoptive son of Carlisle and Esme Cullen. Emmett is the adoptive brother of Alice and Edward Cullen, as well as the adoptive brother of Jasper Hale. He is the adoptive brother-in-law of Bella Cullen and the uncle of Renesmee Cullen.

After being mauled by a bear in 1935, Emmett was rescued by Rosalie Hale, and given a second chance at life after being transformed into a vampire by Carlisle Cullen at her request. Rosalie and Emmett were rarely parted after this, being that they were true soul mates. The pair were integral members of the Cullen family and participated eagerly in removing the numerous impediments it faced. Emmett also changes his eye colour like most vampires. Having enhanced physical vampiric strength, Emmett is the strongest in the Olympic Coven. Emmett has massive muscles which cannot grow since he is a vampire. Emmett is married to Rosalie; they have a strong connection together.

Early Life

Emmet's early life before he became a vampire is never fully explained in the series, although it has been said that he worked on the railroad with his older brothers. Emmett McCarty was changed into a vampire by Dr. Carlisle Cullen in 1935, two years after Rosalie Hale had been changed. When Rosalie came across him, Emmett was being mauled by a bear in the mountains of Tennessee. He had nearly died from the attack, but Rosalie saved him and carried him over a hundred miles back to Carlisle. Rosalie was noted as saying that it took nearly all her strength not to kill him. She also said that she brought him to Carlisle so that he, with his stronger endurance of human blood, could save Emmett. She also said that the reason behind having Carlisle save Emmett and not herself was because she was afraid that if she did it she would end up killing him. Emmett describes this experience as "being saved by an angel who brought him to God". Once Rosalie returned to Carlisle with Emmett, he was changed into a vampire. Many years later, Rosalie confessed to Bella that she saved Emmett from sure death because his innocence, dimples, and curly hair reminded her of her best friend Vera's child, Henry, and that ever since the day she saw Henry she always wanted a baby just like him.

After his painful transformation, Rosalie and Carlisle explained to Emmett that he was a vampire. This did not upset him, however, like Rosalie and Carlisle had thought it would. He put in his own words, "Hell's not so bad if you get to keep an angel with you." He did, however, initially have trouble adjusting to the Cullens' rule of only feeding on animals, and has tasted human blood on several occasions. Emmett later married Rosalie.
Personality and traits
Emmett is described as being very tall, very burly, and to the students at Forks High School, very intimidating. Jessica Stanley refers to him as, "The big dark-haired guy." Standing at 6'5", he is the tallest of the Cullens, towering over Alice by nearly two feet. His strength gives him a rather filled out form, but he is not regarded as being overweight, just muscular. His height helps spread out his weight. He has a round face with dimples and slightly curly, dark brown hair, giving him a childish look. He is the strongest of the Cullens. Like the rest of his family, he has pale skin and golden eyes that darken to black as he becomes thirsty.

He is one of the youngest vampires in the Cullen family, which is why the scent of human blood is sometimes harder for him to resist. He does very well when things get out of hand and he could resist Bella's blood when she was human. Despite being the most intimidating Cullen, Emmett is very loving and caring to his wife Rosalie Hale and the rest of his family.

Emmett loves to laugh and make jokes, and tries to lighten up tense situations with his sense of humor. In Breaking Dawn, he often makes jokes about Bella's sex life, which angers her to the point of yelling. Bella, who is a newborn, challenges him to an arm-wrestling match to make him stop saying anything about it. Of course, as a new born, Bella wins. He was angry and wanted a rematch. He appears to be thoughtless and makes rash decisions. He is also brave, enjoys fighting, and is very competitive. Emmett was upset that he wouldn't be going with Bella in Twilight, until she pointed out that he would have a better chance to fight James if he went with Edward. He thought it would be a good idea to turn Bella into a vampire, and expressed a desire to "pick a fight" with Demetri. He was also looking forward to the fight with the newborns created by Victoria, and the fight with the Volturi over his niece Renesmee.
Powers and abilities
As a vampire, Emmett has many enhanced properties such as superhuman speed and incredible strength. Like other members of the Cullen family, he does have a special ability, his being enhanced physical strength. He uses his "super strength" as his special ability, but has no mental powers. It is hinted by Emmett himself that if Edward was unable to read minds that Emmett would be capable of defeating him in combat. Edward admits, when Bella wants to be trained to fight, that Emmett knows just as much about combat as he, and Edward is on par with the powerful Jasper. In Breaking Dawn Bella, with her newborn strength, beats huge, strong Emmett at an arm-wrestling match. This is explained by the fact that newborn vampires are usually stronger than old ones, but that will eventually pass once the newborn grows older.

"With the dark curls...the dimples that showed even while he was grimacing in pain...the strange innocence that seemed so out of place on a grown man's face...he reminded me of Vera's little Henry."
―Rosalie on Emmett[src]

Rosalie purposefully saved Emmett because of his innocent looking face, his dark curls, and his dimples. He reminded her of her former best friend Vera's child Henry. He thought she was 'his angel'. It was because of her that he was so accepting of his new life as a vampire.
