Main characters

* Isabella "Bella" Swan – The protagonist of the series, teenager Bella is a perpetually clumsy "danger magnet" with dark brown hair and brown eyes. She is often portrayed as having low self-esteem and unable to comprehend Edward's love for her. She has an immunity to supernatural abilities involving the mind, such as Edward's mind-reading ability. After her transformation into a vampire in the saga's fourth installment, Bella acquires the ability to shield both herself and others from "mental harm" from other vampires.
* Edward Cullen – Edward is a vampire who lives with a coven of like-minded vampires known as the Cullen family, who feed on animals rather than humans. Over the course of the Twilight series, Edward falls in love with, marries, and then has a child with Bella. At first, Edward feels a mutual hatred toward Jacob Black because of his love for Bella, but in Breaking Dawn, he comes to see Jacob as a brother and friend. Like some vampires, Edward has a supernatural ability: mind reading. It allows him to read anyone's thoughts within a few miles radius. Bella is immune to his power as a human, but learns how to lower this "shield" after her transformation to a vampire.
* Jacob Black – A minor character in the first novel, Jacob is introduced as a member of the Quileute tribe. He resurfaces in New Moon with a much larger role as Bella's best friend as she struggles through her depression over losing Edward. Although he is in love with Bella, she initially sees him as just her best friend. He and other tribe members can shape shift into wolves. In Eclipse Bella realizes that she loves Jacob, though her feelings for him are overpowered by her love for Edward Cullen. In Breaking Dawn, Jacob finds a soulmate in Bella and Edward's baby daughter, Renesmee, ridding him of his heartache for Bella.
