Pacifica Northwest is the most popular girl in Gravity Falls, Oregon. She is the daughter of the supposed founder of Gravity Falls, Nathaniel Northwest. However, he is soon revealed as a fraud.

History
Pacifica first appears in Double Dipper, where she competes with Mabel for the title of Party Queen at the Mystery Shack party. The crowd clearly favors Mabel; however, she is able to bribe and threaten her way to the top. She then leaves with a large part of the crowd to go to the after party on her parents' boat.

In Irrational Treasure, she makes a speech for Pioneer Day, and insults Mabel for her silliness. She taunts Grunkle Stan when he's put in the stockade. She is later informed by Dipper that her great-grandfather, supposedly the founder of Gravity Falls, was a fraud.

Stuck-up and unfriendly, Pacifica is the stereotypical popular girl. She looks down on "weirdos" such as Mabel and her friends, and lords her ancestry over the people of Gravity Falls.
