**Bill Cipher** was a triangular interdimensional demon, formerly existent only in the mindscape before succeeding in gaining access to the real world. He had been running amok in Gravity Falls, Oregon since being summoned by Stanford Pines over thirty years ago, and was also known for his mysterious demeanor and sadistic humor.

Trillions of years prior to the events of the series, Bill Cipher originated from the second dimension. Bill despised living there, describing it as a dimension of "flat minds in a flat world with flat dreams." He "liberated" his dimension by plunging it into burning chaos, along with everyone he'd ever known, including his own parents.  He eventually took over a boiling, shifting intergalactic foam between dimensions: a lawless, unstable crawlspace known as the Nightmare Realm. Unfortunately, due to the Nightmare Realm's lawlessness and lack of any consistent physics or rules, it was fated to collapse into itself eventually.  After coming to learn of a prophecy that stated he would merge the Nightmare Realm with the third dimension, Bill started coming into contact with humans to accomplish this.

Without a physical form, however, Bill could only access the dreams of the third dimension's beings. In order to make his dealings with mortals easier, he took on the name "Bill Cipher" as his real name would "evaporate one with an expression of horror and ecstasy on their face."  Among his targets were the natives who lived in what would become the town of Gravity Falls, Oregon.

Bill once asked a local shaman named Modoc the Wise to build an interdimensional gateway to the Nightmare Realm, but the result was made out of twigs. When Modoc learned of the prophecy that foretold of an apocalyptic event that would stem from interactions with Bill Cipher, he lit himself on fire in an effort to avert it.

The natives eventually discovered a way to defeat Bill by using a zodiac with ten symbols. They left behind elaborate cave paintings about their encounter with the demon, including how to summon him, and more importantly, a warning never to read the incantation that would summon Bill aloud. The valley was deemed a "cursed land" by the natives, who evacuated around 1000 AD.  The area would eventually be rediscovered by Quentin Trembley and repopulated by pioneers, giving rise to the town of Gravity Falls.

In the late twentieth century, a young man named Stanford Pines, who had spent the past six years investigating the town's plethora of unnatural creatures and oddities, hit a roadblock in his research and was left without answers as to how the improbabilities of Gravity Falls had come to be. During the roadblock, he uncovered the ancient cave containing the ancients' stories of Bill Cipher. Heedless of the warnings, Ford repeated the incantation aloud, summoning Bill into his mindscape. Bill recognized Ford's brilliant but cocky and insecure nature, and his near-friendlessness as ideal conditions for manipulation, choosing to introduce himself to Ford as a muse who chose one brilliant mind every century to inspire.

It was Bill who revealed to Ford that Gravity Falls' weirdness was caused by a rift between dimensions, through which the other side's weirdness leaked through. With Bill's assistance, Stanford drafted blueprints to create an inter-dimensional gateway beneath his home and recruited his college friend Fiddleford McGucket for assistance. As Bill and Ford's partnership seemingly grew to friendship, Ford seemed to develop an obsession with Bill's powers, collecting triangular memorabilia such as rugs and statues, modeling his home's architecture in his image, converting his private study into a place of worship. He even allowed the demon to enter his mind; this, along with the amount of information he seemed to simply produce on the spot, made Fiddleford increasingly uneasy of the portal and of Ford's mysterious collaborator, as Ford never mentioned Bill's identity to his partner.

On January 18, 1982, Ford and Fiddleford performed their first trial with the active portal, which quickly went awry, as the rope that was attached to the dummy they intended to send through the portal became tangled with Fiddleford, sending him briefly through the portal head-first. Upon his return, an alienated Fiddleford muttered incoherencies before uttering a prediction about "the beast with just one eye." In *Gravity Falls: Journal 3*, it is revealed that Fiddleford saw Bill removing his exoskeleton to feed. He promptly abandoned the project.

The suspicion planted in him by Fiddleford led to a confrontation between Ford and Bill, during which Ford learned that Bill had tricked him, as the portal was meant to act as a gateway to the Nightmare Realm, allowing the demon to bring chaos and destruction into their universe. Horrified and betrayed, Ford shut down the project and attempted to destroy all knowledge of the portal, before accidentally falling through it himself. Bill either could not see Ford in the thirty years he spent lost in other dimensions or didn't care to, as Ford would remark that they had not seen each other in many years. With the loss of his human pawn, Bill also lost physical access to the third dimension.

he eventually found an organistation that would eventually become the alliance of evil. pitying the fact that they had not yet had a godly member, he met the scientist supreme in his dreams and made a deal with him. he controlled the scientist while he was making big decisions but let him otherwise live his life. using this to his own advantage, he improved the organisation, inventing the first incarnation of the modern alliance of evil.

In an attempt to take over the Mystery Shack once again, Gideon Gleeful summoned Bill. Gideon told him to steal Stan Pines' safe combination directly from his head so that Gideon could steal the Shack's deed. Bill agreed, but in return, Gideon would have to help him in his own plans, which are not revealed to the viewer. Gideon agreed immediately and the two shaked on it. Unbeknownst to Gideon, Mabel and Soos witnessed the deal in the forest, and get Dipper's help to follow him into Stan's mind.

Once inside Stan's head, Bill confronted the trio and brags that he knows what they're all thinking. To prove his statement, he summoned Xyler and Craz from Mabel's imagination. He tricked Mabel and Soos into looking for the memory of Stan's safe combination first, knowing they'd lead him straight to it. At some point, Soos was separated from everyone else, and Bill took his place. Once they found the correct memory he took it and nearly escaped with it. But while he read the combination out loud to Gideon (to whom he is connected), Mabel shot the memory door into another memory of the bottomless pit with a nyarf dart. Gideon broke off the deal, to Bill's fury. Bill turned his anger toward Mabel and Soos by bringing their nightmares to life and killing Xyler and Craz.

Dipper returned in a timely manner and told Mabel and Soos that while they are in Stan's mindscape they can do whatever they want. They battle Bill and he is nearly defeated. Just as though it seems he will be forced out of Stan's head, he put a stop to everything instead. Impressed, he decided to let them go, and after warning them of a mysterious darkness that will change everything they care about, he told them that he'll be watching them. He left in a representation of the zodiac, almost identical to the one that appears in his entry in *Journal 2*.

he then captured Doctor Strange and pitted him against his henchmaniacs in an arena. After the henchmaniacs were defeated, he created the Nightmare Strange but after the Nightmare Strange was defeated he disintegrated the nightmare strange with a single blast.

Bill returned when Dipper was trying to figure out the password for the laptop from "Into the Bunker." He offered the laptop's password in return for a favor, but Dipper refused the offer. Later, at the moment the laptop is on a countdown for complete data erasure after too many failed password entries, he appeared again and Dipper accepted the deal of trading a puppet to obtain the password.

Bill took over Dipper's body as his "puppet" and destroyed the laptop. He then followed Mabel to her puppet show in pursuit of Dipper's journal, which was being used as a prop in the show. After Mabel was informed of Dipper's body having been stolen by him, he found her with the journal as she was retrieving it for Dipper. He almost swindled her out of it but ended up in a fight with her. He ended up losing because Mabel used Dipper's physical weakness and exhaustion to her advantage. As he collapsed, he was thrust out of Dipper's body. Bill possessed the Dipper puppet afterward and says that he would return. However, Mabel activated the pyrotechnics of the play, destroying the puppets and removing any vessel Bill could use to talk to the kids.

In "Northwest Mansion Mystery," he appeared on a tapestry hovering over a forest fire with two men either begging for mercy or worshiping him while skeletal corpses are underneath them, foreshadowing bad events.

At the end of "The Stanchurian Candidate," after a prison-bound Gideon failed to get his father elected mayor, he is shown to have drawn Bill Cipher's zodiac on his cell wall and hidden it behind a cat poster. The symbols on the zodiac have been changed around, and some have been altered. Gideon tore down the poster and completed the drawing by drawing Bill's eye before telling it he's ready to make a deal.

In "The Last Mabelcorn," Bill Cipher appeared in one of Ford's dreams, telling him that he's been preparing for "the big day," going on to say that Ford can't keep the inter-dimensional rift safe forever. Bill throwed a copy of the rift down to the ground, opening a red triangular portal in the sky and setting fire to Ford's mindscape. Ford yelled at Bill to leave his mind, telling him he has no dominion in the real world. Bill left through the portal, telling Ford that "things change."

Far later in the episode, Bill appears in flashbacks as Ford explains his time spent with the demon to Dipper. In the past, Bill and Ford were partners. Bill could enter Ford's mind at any time, and with his help, Ford built the portal. However, after Fiddleford came out of the portal traumatized by the horrifying things he saw, which were Bill's actual plans, Ford realized Bill had lied to him. He confronted Bill, who revealed his plan to merge the Nightmare Realm he comes from with the real world, causing the apocalypse. Ford broke off his partnership with Bill then and there, despite Bill's warnings that he couldn't stop the rift from happening. Ford shut down the portal and swore never to trust Bill again.

At the end of the episode, Bill watches from the Nightmare Realm as Ford and Dipper manage to create a "Bill-proof" barrier around the Mystery Shack by using moonstones, mercury, and unicorn hair. Undeterred, Bill decides to possess someone outside the shack instead.

Near the end of "Dipper and Mabel vs. the Future," Bill approaches Mabel by possessing Blendin Blandin, recognizing Mabel's wishes of wanting summer to never end. Bill (as Blendin) convinces Mabel to give him the inter-dimensional rift, which he says can be used to create a "time bubble" that can make time stop. Mabel gives Bill the rift, which he promptly smashes with his boot. Bill reveals himself and leaves Blendin's body, knocking out Mabel with a snap of his fingers and initiating Weirdmageddon.

In "Weirdmageddon Part 1," after opening the rift, Bill gains a physical form and imprisons Mabel in a bubble. He introduces himself to the people of Gravity Falls, claiming to be their new ruler as well as introducing his friends to the people. The townsfolk refuse to submit, but Preston Northwest welcomes him instead, offering to be one of his "horsemen of the apocalypse." Bill thinks about the offer but instead decides to disfigure Preston's face, creating fear in the people. He begins "redecorating" the town by unleashing Eye-Bats that petrify and abduct the townspeople, summoning the Fearamid, and sending out bubbles that instill madness in everything they touch. Bill recreates the opening theme song in the process.

When Bill and his friends prepare to cause havoc, Ford attempts to shoot Bill back into the rift with his quantum destabilizer but only hits his tophat. When Bill notices Ford and Dipper, he blasts the clock tower. Ford, pinned under rubble, begins to tell Dipper that there's another way to defeat Bill. He is cut short when Bill appears, towering over Ford. Bill captures Ford and presents him to his friends, telling them that Weirdmageddon wouldn't be possible without Ford. Bill makes an offer with Ford and tells him it's not too late to join his side. Ford refuses, so Bill turns him into a golden statue to use as a "back-scratcher." Dipper, who has gotten back to street-level, yells that he's had enough. Bill flies over to Dipper, asking the boy what he could possibly do to defeat him in one shot. Dipper flips through Journal 3, trying to find Bill's weakness. With no answers, Dipper panics, and leaps towards Bill, trying to punch him. In response, Bill creates a forcefield around his eye, knocking Dipper backwards, causing him to fly into a tree. Bill then telekinetically seizes the three journals, burning them in front of Dipper, with two crippled pages surviving. Bill tells 8 Ball and Teeth that they can eat Dipper for a snack. Bill then converts a random car into a sleek getaway ride for himself and his other friends. The car flies away to the Fearamid leaving Dipper, 8 Ball, and Teeth behind.

Bill and his friends are later seen having a rave party inside the Fearamid. Suddenly, the Time Paradox Avoidance Enforcement Squadron, Blendin Blandin, and the Time Baby barge in, attempting to arrest Bill for possessing Blendin and almost destroying reality. Bill vaporizes the Time Police and Time Baby instantly, and the party resumes. 8 Ball and Teeth approach Bill, informing him they failed to eat Dipper. They ask him if he's worried about Dipper freeing Mabel, but Bill says he's not concerned, and that he has "someone on the case."

In "Weirdmageddon 2: Escape From Reality," Bill has been in power for four consecutive days. Most of the townsfolk have been petrified and stacked into a "massive throne of frozen human agony" for Bill. He announces his plan to take Weirdmageddon worldwide, and the demons make their way toward the edge of Gravity Falls. But instead of escaping to the rest of the world, they hit a strange force field-like energy dome that keeps Bill and his chaos stuck in the town.

Later in the episode, Bill is angered and unable to understand why he and his friends aren't able to extend their reach and leave Gravity Falls to dominate the world. He realizes that Ford is the only one able to understand the shield and contemplates his next move. He is interrupted by Keyhole, who informs him Gideon, Mabel's jailer, has failed to stop Dipper, allowing him and his group to enter Mabel's bubble. Bill is not worried by this, calling Mabel's bubble one of his most diabolical traps yet. He asks for Gideon and tells Keyhole to take the day off.

In "Weirdmageddon 3: Take Back The Falls," Bill reverts Ford from his gold state. He explains to Ford that he, along with the rest of his friends, can’t escape Gravity Falls. Ford thinks that this is due to a natural magnetism attracting weirdness to Gravity Falls, the event he’s studied for years, a force so strong that it forms a barrier that prevents that weirdness from going outside the town. He says there’s a way to break this barrier, but he’d never tell Bill. Bill tries to persuade Ford by telling offering him unlimited power in a world without restrictions or laws. Ford again refuses, calling Bill insane. Bill decides to find the equation needed to break the barrier in Ford’s mind. However, Ford reminds Bill he can’t unless he makes a deal with him. Bill decides to try and find Ford’s weakness and force him to make the deal, chaining him up further.

Bill is later seen torturing Ford by blasting him with lasers until he agrees to his deal. Though Ford is in pain, he still refuses to give in. Before Bill can start torturing Ford again, he is interrupted by the Shacktron, a gigantic mech created by Old Man McGucket, with the help of Dipper, Mabel, and various townsfolk. They converted the Mystery Shack into a powerful machine to fight Bill and rescue Ford, who knows Bill's weakness. Bill finds it "adorable" that the refugees are fighting back, and orders his henchmaniacs to fight them. However, his minions are quickly defeated by the Shacktron, and Bill is upset as Ford congratulates Dipper and Mabel for their efforts. Bill realizes Ford cares about the twins, and wonders if torturing them will be more effective than torturing Ford. Bill turns Ford back into a gold statue and flies over to the Shacktron. He attempts to crush the Shacktron with a giant fist, but it remains intact thanks to the "Bill-proof" barrier surrounding the Mystery Shack. Bill becomes enraged and repeatedly punches the Shacktron. The refugees use the dinosaur attached to the Shacktron's left arm to tear out Bill’s eye and distract him. Realizing now is their chance to rescue Ford, a team composed of the twins, Stan, Soos, McGucket, Wendy, Pacifica, and Sheriff Blubs is ejected out of the Shacktron, using parachutes made out of Mabel's sweaters to land inside the Fearamid.

Everyone lands right next to the human throne, but Dipper is unable to figure out how to unfreeze everyone. Gideon Gleeful, trapped in a cage hanging from the ceiling, explains that Mayor Tyler is the load-bearing statue in the human throne, and if he’s pulled out, the whole throne will fall apart. When Dipper does so, it sets off a chain reaction. As the chair collapses, Gideon’s cage is knocked to the ground and breaks, freeing him. The residents are returned to normal, and Ford unfreezes as well. When Dipper and Mabel ask Ford what Bill’s weakness is, he explains that the way to thwart Bill is by using a zodiac with ten symbols. When each person that correlates with a symbol stands on a drawn version of the zodiac and they hold hands, it can create a force strong enough to vanquish Bill. Meanwhile, Bill is still fighting the Shacktron. It manages to pin Bill to the ground, but Bill realizes its legs aren't inside the unicorn barrier. Bill utilizes this weak spot to flip the Shacktron over, tear off a leg, and smash it into the Shacktron, sending it flying. Back in the Fearamid, the townsfolk that is not represented in the zodiac run away, leaving only Dipper, Mabel, Soos, Wendy, Gideon, Robbie, Pacifica, McGucket, Ford, and Stan. For a moment, it seems that they will be able to complete the ritual. However, after Ford corrects Stan on his grammar, Stan pushes Ford, breaking the link. The two begin to fight as Mabel and Dipper try to stop them. While they’re distracted, Bill looms above them, having beaten the Shacktron and regenerated his eye.

Bill sends a wave of fire at them, burning the zodiac away. He also traps Stan and Ford, binding them with ropes. The resistance prepares to fight against Bill, but the demon snaps his fingers and turns everyone but the Pines into tapestries showing their screaming faces. Bill then imprisons Dipper and Mabel in a triangular cell. Bill says he’ll spare the twins if Ford lets him into his mind, giving him one last opportunity. The twins yell at Ford not to do it, causing Bill to angrily fly up to them. Mabel quickly takes out her can of spray paint and sprays Bill’s eye, distracting him again and freeing Stan and Ford. While Bill’s distracted, Dipper takes out his size-altering flashlight and enlarges the cell, making it so he and Mabel can walk through. He and Mabel goad Bill into chasing them down a long hallway. As Bill moves to follow them, Stan and Ford try to escape.

However, Bill places them inside a larger cell like the one he put the twins in. Bill then changes into a monstrous red and yellow form and chases the kids throughout the Fearamid, threatening to disassemble their molecules. After recapturing the twins, he gives Ford an ultimatum—let him into his mind, or one of the twins will be killed. Ford reluctantly surrenders as Stan objects. Bill removes the cell and ties up Stan. Ford’s only condition to the deal is that he lets his family go. Bill accepts as he shakes hands with Ford. Bill’s physical form turns to stone as his mental form goes inside Ford’s mind.

Bill was happy that inside Ford’s mind is "a perfect, calm, orderly void" (a bleak white landscape) with a single wooden door. When Bill opens it, he’s greeted by Stan playing paddleball inside the Mystery Shack. Stan reveals that while the demon was chasing Dipper and Mabel, he and Ford swapped clothes and pretended to be each other so that Bill would enter the wrong mind. In the real world, Ford takes out the Memory Gun, setting it to erase Stan’s memory completely. In the mindscape, Bill tries to call the deal off as the door shuts and the room becomes enveloped in blue flames. Stan explains Bill is going be erased by the Memory Gun, but the demon retorted, asking Stan if he realizes that his mind is also being destroyed. Bill tries to escape and resorts to bargaining with Stan, but Stan doesn’t budge because Bill's powers were erased. The man tells him that Bill's real wiseguy but made one fatal mistake: messed with his family. Bill explains that Stan's making a mistake and will give him anything that he would desire, until his form becomes heavily distorted as he speaks backward messages, and attempts to reach out to Stanley. He punches the weakened Bill into nonexistence as his mindscape becomes consumed by the flames caused by the Memory Gun. Following Bill's defeat, everyone trapped as the tapestries are freed. Outside the Fearamid, Bill’s henchmaniacs are sucked back into the portal, with the bricks of the Fearamid not far behind. The portal itself closes and explodes into a great shockwave, returning the entirety of Gravity Falls back to its own version of normal. The only thing that remains of Weirdmageddon is Bill’s petrified physical form.

he returned when the scientist supreme, annoyed at bill`s death, brought him back to life via axolotl god, but he was apprehended and they were both sent through a portal into stan's mindscape where they were destroyed. he may alo have been brought back to life by thanos during the battle of coruscant, but this idea has been debunked.
