Jacob Black

Jacob is described as a "happy person" who extends his happiness to the people around him. Jacob is a shape-shifter or "werewolf" of the Quileute tribe, former Beta of the Uley Pack, Alpha of his own pack, the Black Pack, and part of the tribal council. He is one of the few who dislike being wolf and wants nothing more than to be rid of his inner beast, but learns to adapt to it. His body temperature is warmer than a human's body should be, reaching about 108.9 °F, which allows him to withstand very cold weather. Members of the Quileute wolf-pack do age if they do not phase for a long time; His body has physically grown to the equivalent of a 25-year-old but stops aging after that. Jacob is the largest and strongest wolf of the pack. Once they begin phasing, a Quileute shape-shifter may "imprint"—a method of finding one's soulmate—on someone, and will act as whatever that person wants or needs, whether it be an older brother, friend, protector, or lover. When he was 9 years old, his mother Sarah died in a tragic car crash. He recovered from the pain fairly easily, thanks in part to his sisters, Rachel and Rebecca, filling the role of mother for him as much as they were able. Rebecca married a man named Solomon Finau and moved to Hawaii, while Rachel moved away to attend Washington State University as soon as she finished high school. Since his sisters were away, he became his father's only company at home, especially after he became wheel-chair bound due to diabetes. However, he did not resent taking care of his dad; in fact, he enjoyed his father's company, though he refused to believe in his family legends and traditions. When the Cullens first moved to Forks, Jacob did not understand his father's aversion. After a while, he began tuning out most of what his father said. He was once in love with Bella Swan, but has since moved on after she chose Edward Cullen over him.
