Frozen at age eighteen and born in 1915 in Rochester, New York, Rosalie was the daughter of a banker. Tall, statuesque, and has long, wavy blonde hair, Rosalie is described as being the most beautiful person in the world. As a human, Rosalie was a woman who had beauty, elegance, class, and eyes resembling violets. A quick engagement with Royce King II led Rosalie to become extremely envious of her good friend Vera and her baby boy. While visiting them one night she noticed that she did not share the same relationship with Royce as Vera did with her husband. But on her walk home and Rosalie met an intoxicated Royce with his friends. Royce bragged about his fiancée's beauty, leading to her being beaten, presumably raped, and left to die. Carlisle came across her as he was a doctor in Rochester at the time and decided to change her into a vampire (hoping she would be a mate for Edward). After her transformation, she tortured and killed those who had beaten her, including Royce, but did not drink their blood.
Rosalie Lillian Hale is the adopted daughter of Esme and Carlisle Cullen, adoptive sister of Edward, Alice, and Jasper, and wife of Emmett. Rosalie throughout the books acts as the sister of Jasper and that they are Esme’s niece and nephew. Gorgeous even compared to other vampires, Rosalie acts and looks like a model. She is mean to Bella due to jealousy of her being human, and not wanting Bella to choose a life as a vampire. Rosalie is known for being vain and self centered. She wishes to be human and have children so much so that she would give up her immortality and beauty for it. Rosalie eventually warms up to Bella and wishes to reveal her past to Bella with the hopes that she will choose to stay human. She also joins the fight against a group of savage newborn vampires. With her new bond with Bella, Bella contacts Rosalie after finding out she is pregnant, knowing that Rosalie has always wanted children. Rosalie stays by Bella's side throughout the pregnancy, defending her choice to keep the baby, and Rosalie acts as a guardian to the child, Renesmee, taking care of her while Bella is going through her transformation into a vampire.
