Intro. Bill Cipher, also known as Bill Cipher, is a magical creature, a powerful demon capable of entering a person's subconscious, and the main antagonist of the series. Bill is known for his mysterious behavior and sadistic humor. He has been a terror in Gravity Falls since he was summoned by Ford Pines more than thirty years ago. He is the main antagonist of Gravity Falls, despite the fact that he did not play a major role until the episode "Prisoners of the Mind". He, as well as the symbol he is based on (the All-Seeing Eye), appear frequently in Gravity Falls. Bill Cipher was also the unseen author of the cryptograms in the online game Rumble's Revenge, where his name is derived by adding up all the capital letters in the cryptograms. The result will be: "MY NAME IS BILL."
