Alice Cullen (born Mary Alice Brandon) is the adopted daughter of Carlisle and Esme, adoptive sister of Edward, Rosalie, and Emmett, and wife of Jasper. Alice is described as being petite and pixie-like, with a graceful gait and hair that is short, spiky, and black. Her special ability is to see the future, an enhanced version of her ability to have premonitions as a human. However, her ability is limited; she is only able to see the outcome of a decision once it is made. Due to this, decisions made in the spur of the moment can not be foreseen. Alice can see futures involving humans and vampires, but is unable to see those of werewolves or half-breeds, such as Renesmee. Alice theorizes that she can see vampires very clearly because she is one, can see humans somewhat less clearly because she was one, and cannot see werewolves or half-breeds because she never was one. Alice is bubbly and optimistic, and loves and cares for Bella like a sister. She is also close to her brother Edward, and enjoys shopping, make-overs, and throwing parties. Alice's early history is vague, as she remembers nothing about her human life and woke up alone as a vampire. It is eventually revealed that she was born around 1901 in Biloxi, Mississippi, and was committed to an asylum because she had premonitions. Alice was transformed by an old vampire who worked at the asylum to protect her from James, a tracker vampire who was hunting her. After some research, Alice found her grave and discovered that the date on her tombstone matches the date of her admission to the asylum. Through her research she additionally discovered that she had a younger sister named Cynthia, and that Cynthia's daughter, Alice's niece, is still alive in Biloxi.
Isabella "Bella" Marie Swan is a clumsy, accident-prone teenage girl who moves from Phoenix, Arizona, to Forks, Washington, to live with her father, Charlie. Though many boys are attracted to her when she arrives, two people stand out mostly of all. Edward Cullen, Alice's brother, and her best friend Jacob Black. As she comes to love them both, her life is turned upside down, as though Edward and Jacob are enemies, Edward the vampire and Jacob the shape-shifter.
Renesmee "Nessie" Carlie Cullen is the half-vampire, half-human daughter of Edward Cullen and Bella Swan, born on September 10, three days before Bella's nineteenth birthday. Her name is derived from the amalgamation of the names of Bella's mother, Renée, and Edward's adoptive mother, Esme. Her middle name, Carlie, is a portmanteau of the names Carlisle, Edward's adoptive father, and Charlie, Bella's father. She has the same facial features and hair color as Edward, but has her grandfather, Charlie Swan's, curly hair, and brown eyes like Bella. Bella and Jacob describe her as being the most beautiful person in the world, even though she is so young. Her heart pumps blood, giving her a blush, and her pale skin glows in the sunlight. Her skin is warm and soft to the touch, but it is as strong as a vampire's. Renesmee can survive on either blood or human food, though she prefers blood, and she does not produce venom. Her special abilities are transmitting thoughts to others by touching their skin and penetrating shields, the opposite abilities of each of her parents. Renesmee rapidly grows both mentally and physically, able to speak only seven days after her birth. Her intelligence stuns everyone - Bella and Edward especially - as she is able to understand what is happening around her when the Volturi arrive. Jacob Black nicknames her "Nessie" because he considers her full name to be a mouthful, though Bella strongly dislikes her child being nicknamed "after the Loch Ness Monster". She is 17 years old and will not age anymore what so ever.
