WKLV OLNHQHVV FRPHV ZLWK D SULCH LQVLGH

**Bill Cipher** is the main antagonist of the Disney animated series *Gravity Falls*, created and voiced by series creator Alex Hirsch. He is an extradimensional entity hailing from the 'Nightmare Realm', a primordial foam between dimensions, who invades unconscious minds and proposes deals with individuals to further his ultimate goal of merging his home dimension with that of the physical world.

## Canon

### Background

Bill Cipher was born as a denizen of the second dimension, a universe inhabited solely by flat two-dimensional entities. Bill openly despised his home and its inhabitants, describing them as "flat minds in a flat world with flat dreams", and ultimately 'liberated' the dimension by burning it to the ground. Following this event and at least one trillion years prior to the events of *Gravity Falls*, Bill came to rule over the Nightmare Realm, a lawless and unstable space between dimensions with no natural connections to the rest of the multiverse. Unfortunately, The Nightmare Realm's inherent instability meant that it was destined to decay and collapse upon itself in time. To avoid being trapped inside when the dimension met this fate, Bill began to pursue a prophecy foretelling that he would merge the Nightmare Realm with the third dimension.

Due to his lack of a corporeal form in the third dimension, Bill could only influence the world by accessing the dreams of its inhabitants and making deals with them, a pursuit which caused him to adopt the name 'Bill Cipher' for ease of communication (as his true name would "evaporate one with an expression of horror and ecstasy on their face"). Bill particularly focused his attention on the ancient inhabitants of what would later become the town of Gravity Falls, Oregon, a documented hotspot for anomalous activity. Over the course of thousands of years, Bill made deals with humans in the region intended to further his ultimate goal: the creation of a extradimensional portal that would allow him and his fellow denizens of the Nightmare Realm passage into the third dimension.

   His most successful effort in this regard was through the manipulation of Stanford Pines, a young researcher living in the region. Bill and Stanford, with the assistance of the latter's college friend Fiddleford McGucket, collaborated to construct an operational multiverse portal which Bill promised would solve all of the mysteries of Gravity Falls; however, an incident in the testing of the device led to Stanford becoming aware of Bill's deception and shutting the project down, preventing the merging of the Nightmare Realm with the third dimension. Stanford later accidentally fell into the portal himself, and had several confrontations with Bill over the course of the thirty years that he spent trapped there.

### Events of *Gravity Falls*

   After a period of inactivity in the physical world, Bill made his return to Gravity Falls upon being summoned by Gideon Gleeful, a child psychic who sought to use Bill's power to destroy his primary competition in Gravity Falls, the Mystery Shack. Bill agreed to invade the mind of Stanley Pines, Stanford's brother and the owner of the Shack, to find the code for the safe containing the deed to the establishment for Gideon. In exchange, Gideon agreed to help him with an undisclosed favor. This endeavor led to Bill's first encounter with Stanley's nephew and niece, Dipper and Mabel Pines, as well as the handyman Soos. After a confrontation with the trio that led to his deal with Gideon falling apart, Bill voluntarily vacated Stan's mind, warning of an approaching darkness and that he would be watching the group.
Bill proceeded to monitor the residents of Gravity Falls throughout the summer thereafter, having several more encounters with them as he awaited the prophesized day in which he would cross over into the third dimension.

   Notably, he tricked Dipper into a deal that allowed him to possess the boy's body in an effort to prevent him from finding answers regarding Stanford Pines's multiverse portal. However, he was thwarted in his efforts to destroy Ford's journal by Mabel, who exploited the physical weaknesses and exhaustion of Dipper's body to force Bill out of it.

     When the portal was later reactivated by Stanley, allowing Stanford to return to the third dimension, Bill set his sights on an inter-dimensional rift left behind by the portal's activation that would allow him passage into the mortal world if released. Despite efforts by Dipper and Ford to contain the rift and ward him off, Bill was able to obtain the rift by manipulating Mabel, at the time emotionally distraught over Dipper's plans to remain in Gravity Falls with Ford, into giving it to him in exchange for an everlasting summer. Bill then proceeded to smash the container of the rift, opening a gateway to the Nightmare Realm and finally allowing him to pass through into the third dimension.

    Upon entering the third dimension and gaining physical form, Bill and his fellow denizens of the Nightmare Realm proceeded to initiate the event called 'Weirdmageddon', distorting reality and causing wanton chaos throughout all of Gravity Falls with the intention to later spread the madness across the universe. However, as he later discovered, a barrier of 'weirdness magnetism' prevented Bill and his friends from leaving Gravity Falls. Bill began to interrogate a captured Stanford for a means of bypassing the barrier -- being unable to simply invade his mind due to a metal plate Ford installed in his head -- but was unable to get the answer out of him before the survivors of Weirdmageddon rallied together to confront him and save Ford. In the ensuing confrontation, Bill's friends were defeated using a mech constructed from the Mystery Shack by McGucket, but Bill was able to subdue the survivors and capture the rest of the Pines family with the intention of torturing them to make Ford talk. After definitively capturing Dipper and Mabel following an escape attempt by the twins, Ford finally surrendered and allowed Bill to enter his mind. When Bill did so, however, he discovered that he had actually entered the mind of Stanley, who switched clothes with his brother and pretended to be him in order to deceive the demon.

     Meanwhile, Ford used a memory-erasing gun constructed by McGucket to erase Stanley's mind, with the intention of erasing Bill along with it. Bill attempted to escape using his powers and by bargaining with Stan until his form began to weaken and destabilize, before finally being destroyed by Stan once and for all.

    With Bill defeated, the effects of Weirdmageddon began to reverse themselves, returning Gravity Falls to relative normalcy; the only thing left over from the event were the petrified remains of Bill's physical form.
