Bill Cipher is a powerful, interdimensional dream demon in the TV Cartoon series Gravity Falls that can be summoned and released into a person’s mind. He resembles a one-eyed, yellow triangle with a top hat and a bow tie, superficially similar to the Eye of Providence. Bill first appears physically in “Dreamscaperers;” however, many references to him are hidden in previous episodes as images or sentences that flash across the screen. He has a snappy sense of humor but loses his temper quite easily due to impatience. He can read people’s minds and memories, shift forms, warp reality, maintain cross-dimensional awareness, possess bodies, encrypt and decrypt codes, and shoot laser energy blasts from his eye and fingers.
