Bill Cipher

Intro Bill Cipher, the main antagonist of Gravity Falls, is a powerful dream demon from the 2nd dimension, over a trillion years old. Looks: He's a yellow, triangular being resembling the Eye of Providence, sporting a black top hat, bow tie, thin limbs, and one large eye. Fanart often depicts him in a human form with similar attire. Powers: Bill possesses vast reality-warping abilities, mind control, dream manipulation, telekinesis, pyrokinesis, and can enter people's minds. He can make deals, often with tricky clauses, and his powers increase significantly in the physical world, especially during Weirdmageddon. Everything About Him: Bill is a chaotic, manipulative, and humorous entity with a desire to merge his nightmarish dimension with the real world. He destroyed his own dimension out of boredom. In Gravity Falls, he initially works with Gideon Gleeful, then becomes the primary threat, culminating in the apocalyptic event "Weirdmageddon." His plans are ultimately foiled by the Pines family, and he is seemingly erased from existence, though hints of his survival remain. He represents chaos and the dangers of absolute knowledge.
