Pacifica Northwest is the most popular girl in Gravity Falls and great-great-granddaughter of supposed town founder Nathaniel Northwest. In the summer of 2012, during the stay of Dipper and Mabel Pines in Gravity Falls, Pacifica ended up forming a great rivalry with them, especially with Mabel. Pacifica is a stuck-up, egotistical, arrogant, snotty, rude, and mean girl who is also a stereotypical blonde popular girl as she has money, style, and talent. She is a diva who looks down badly on "weirdos" such as Mabel and her friends, Candy and Grenda, and lords her ancestry over the people of Gravity Falls. Her parents spoil her and encourage her behavior which has greatly affected her psyche, to the point of valuing what her parents drive into her: money, winning, and looks. In reality though, Pacifica is a tragically misguided character who only acts the way she does because her parents keep her in line with their tight standards on what being a Northwest entails and also with Pavlovian behavioral conditioning, to which she is always forced to obey despite her objection.
