Overview... inter-dimensional demon plotting to destroy Earth. This sadistic floating one-eyed sentient triangle with a top hat has a pair of mortal enemies and they’re… two twelve-year-old twins named Dipper and Mabel. When a portal opens from his dimension to ours, he turns the town of Gravity Falls into a nightmarish hellscape.
Personality... psychotic, fast-talking, and evil. Bill has the power to demonically possess humans in our dimension and uses that power to gain the upper hand in his ongoing war on the laws of physics. Bill’s ideal world is a never ending party of chaos and, frankly, his march toward achieving his goal is ruining Mabel and Dipper’s awesome summer away from home.
