Bill Cipher
Bill Cipher is the main antagonist of Gravity Falls, a Disney Channel animated series created by Alex Hirsch. Like several other characters he is voiced by Hirsch himself. Bill is an interdimensional, metaphysical demon who seeks to take over the "3D world". He mainly appears as a yellow triangle resembling the Illuminati symbol wearing a bow tie and top hat. Bill is very manipulative, and he is shown offering deals to multiple characters to further his goals, and also has the ability to shapeshift, alter reality, and enter the minds of people. The character made his official debut in Dreamscaperers, the penultimate episode of the first season; prior to this episode his existence is hinted at via background objects and drawings showing his likeness.
Bill's simple yet unique appearance (for a villain), snappy humor, and the mystery surrounding his lore has made him arguably the most popular character from the series. He first appeared in Mr. /co/lympus 2020, a tournament characterized by its massive amount of role-playing, and advanced to the second round by defeating the show's MC Dipper Pines. Afterwards, Bill became involved in the "gay wedding" arc when he faced the groom Samurai Jack; the demon then provided one of the highlights of that year's threads when he used the power of Quads to send the entire wedding to Hell.
