"About three things I was absolutely positive. First, Edward was a vampire. Second, there was a part of him — and I didn't know how potent that part might be — that thirsted for my blood. And third, I was unconditionally and irrevocably in love with him." ~Bella

Isabella "Bella" Marie Swan (later Cullen), was born to Charlie Swan and Renée Dwyer on September 13, 1987, and is the main protagonist of the Twilight Saga. In Twilight, she is a 17-year-old girl who transfers schools from Phoenix, Arizona to Forks, Washington to live with her father Charlie, where she meets and falls in love with a vampire, Edward Cullen.

In Breaking Dawn, she marries Edward on August 13, 2006 and becomes a member of the Olympic Coven. She is transformed into a vampire by Edward after nearly dying giving birth to their daughter, Renesmee Cullen, a vampire/human hybrid. Bella is the daughter-in-law of Edward Masen Senior and Elizabeth Masen, as well as the adoptive daughter-in-law of Carlisle and Esme Cullen. She is the adoptive sister-in-law of Alice and Emmett Cullen, and of Jasper and Rosalie Hale.

As a human, Bella possessed a natural immunity to the mental powers of vampires. After her transformation into a vampire, she develops it into the ability to project a mental shield which she can use to protect others from the psychic powers of other vampires.

When Bella was six years old, they moved to Phoenix, Arizona. During most of her childhood, she would visit her father in Forks for a month every summer, and also spent time with Rachel Black, Rebecca Black and Jacob Black, the children of Charlie's best friend, Billy Black. Bella found the climate in Forks unpleasant, though, and from 2002 onwards, Charlie visited her in Phoenix instead. She briefly took ballet and piano lessons, but quit them after some time because she found them too difficult.

Bella never fit in with her peers in California or Arizona. She had always had the feeling of being a little out of sync with everyone - including her mother, who was her best friend. While her mother was impractical, absentminded and liked to shift from one interest to the next, Bella grew up as the more responsible and independent individual. At an early age, she took over most of the household responsibilities. Sometimes, she would feel like she was the adult and Renée was the child.

During free time, she preferred to sit home and read, in part because she was extraordinarily clumsy. Her naturally responsible nature carried over into her schoolwork, where Bella was generally a straight-A student. Her plan for the future was to get a degree in education and teach, like her mother. Renee's career was the one thing that Bella truly respected. However, she intended to teach at the high school level.

When Bella noticed that Renée felt lonely due to the lack of romance in her life, she encouraged her mother to go on more dates. Eventually, Renée fell in love and married a minor league baseball player named Phil Dwyer. They married on the same month that Bella turned 17. While Phil traveled around for his job, Renée stayed home with Bella; however, Bella, noticing her mother's unhappiness with this arrangement, chose to move in with her father in Forks so Renée could go on the road with Phil during baseball season, leading to the beginning of Twilight.
