Remember, reality is an illusion, the universe is a hologram, buy gold, bye!
―Bill Cipher

Bill Cipher is the main antagonist of Gravity Falls. He is a Dream-Demon with mysterious motives and seems to have a vendetta against the Pines family, especially his old rival Stanford Pines.


Bill is an ancient demon who's older than the galaxy and far greater than other nightmare beings. Bill once lived in the Second Dimension, a place that he soon destroyed and described as a "flat world with flat minds and flat ideas." Bill then became determined of spreading chaos and destruction, which forced him to "liberate" his dimension by destroying everything there, including his own parents. Eventually, he found his way to the Nightmare Realm where Bill soon met up with the Henchmaniacs. In this dimension, Bill had no corporeal form, so he could only access or possess the minds of humans. With this ability, Bill manipulated countless humans so that he could find a way to enter the Third Dimension, then gain a physical form and liberate that dimension as well.

As trillions of years passed, Bill's interactions were recorded throughout the history of humanity. At one point in time, he encountered natives who lived in what would become Gravity Falls, Oregon. The people discovered that Bill was too dangerous and found a way to defeat him using a zodiac with ten different symbols. The people left behind a painting depicting their encounter with the demon, instructions on how to summon him, and a warning to never read it. Stanford Pines would discover this symbol in the late twentieth century when he came to investigate the town, hoping that it would help him in his research on Gravity Falls' anomalies. After a failed attempt to summon the entity, Ford ended up encountering Bill in his dreams, where he offered to help with the answer to Ford's questions of the universe and gain his trust. Ford was blinded by this flattery when he agreed to the deal.

Bill then had Ford build a machine that he claimed would benefit mankind, but in reality, it was a portal for the demon to enter the 3rd Dimension. However, one of Ford's human friends, Fiddleford McGucket, discovered the true nature of the portal and warned Ford before completing their project. Horrified and betrayed, Ford shut down the project and hid all three journals on how to operate it, shifting to working on countermeasures in case the demon ever returned. Bill, however, patiently boded his time for the portal to reactivate.


Before his debut in "Dreamscaperers", Bill appeared frequently in Gravity Falls. He was an unseen character who wrote the cryptograms in the online game Rumble's Revenge. His name and existence are deduced by taking all the capital letters in the cryptograms from Rumble's Revenge, which forms the sentence: "MY NAME IS BILL."

A picture of Bill shows briefly at the end of the opening theme. This is partially an image from his entry in book 2. Encircling him are various symbols that can link to various characters in the show. Most notably, when he appears physically for the first time, he refers to Dipper, Mabel, and Soos, as "pine tree, shooting star, and question mark" respectively. The entry also makes special note of his association with the glasses symbol. It also says, "This old triangular being has appeared in my dreams every night for weeks."

In book 3, the text says "Why is he watching me?" and "Bill has proven himself to be one of the friendliest and most trustworthy individuals that I've ever encountered in my life. What a guy! I honestly couldn't trust him more. Not evil in any way. Bill is a true gentleman." However, the second part is crossed out in red ink. On the next page is "DO NOT SUMMON AT ALL COSTS!" in red block letters, the rest of the page splatted with a dark red substance.

Physical appearance[]

Bill is a triangle with a pyramid design, resembling the Illuminati symbol or the Eye of Providence, with an eye in the middle. Among the bottom part of his body is a brick pattern. In the theme song, Bill has a top hat on, a bow tie, and stick arms and legs, but lacks them in most of his cameos. As a metaphysical demon, Bill is capable of altering his body into a variety of frightening and cubic forms. While he can manipulate his own body at will, wounds on Bill seems to suggest his inside has an organic, flesh-like texture. This is hinted at in the Journal 3, where it says, although encoded, that his outer layer is an exoskeleton that in order to eat he has to remove.


Bill, quite simply, was a master manipulator able to adapt, manipulate, and deceive others through the use of flattery, promises, mind control, or dealings throughout making himself and his objective a mystery. Despite his insane and sadistic ways, Bill was affable, if not obnoxious, to others, but this is only one of the many facades of his unpredictable personality; he is willing to betray, lie, and submit others to a life of misery and torment for his own amusement and shamelessly go back on his deals (whilst technically keeping his promise) through his word lineage and manner of phrases. At times, Bill displays a murderous temper, though seldom seen, and it causes his voice to become deep and guttural, accustom to many beliefs of demonic figures. He also appears to be aware of his insanity, as when Gideon states him as such, he shrugs it off, asking what his point was.

Bill also had a weird and rather sadistic sense of humor. This is displayed during his joyous and maniacal laughter in the face of other peoples and his own pain, such as taking teeth out of a deer and presenting it as a gift to Gideon, switching around every orfice on Northwest's face and, after taking control of Dipper's body, describing pain as "hilarious" whilst continuously self-harming, showing he was also masochistic. This doesn't, however, explain why the Axolotl said, "says he's happy; he's a liar," in the poem stated in the pirates' treasure novel. It could possibly mean that his twisted sense of humor is just an act that he uses to take his mind off the fact of his family and dimension destroyed by his own hand. Or he enjoys watching others feel the pain that he had carried for billions of years and going. Either way, Bill does have some sort of guilt towards destroying his home, as seen in the verse, "wishes to go home but can't return."

Despite his treacherous nature, Bill does have a twisted sense of honor. He will follow through on deals and keep his word, assuming if he's in the mood for it but strongly prefers the immoral way and largely feels no incentive or debt for anything. Gratuitously, he allowed Gideon control over Gravity Falls after he took a physical form and control of the world. Outside of this, Bill displayed a willingness to go against his own rules, preparing to invade Ford's mind without his consent, before being reminded that he cannot do that without engaging a deal with the person. He is not above torture or blackmail to obtain what he wants such as attempting to force Ford to accept his deal through intimidation and threatening to murder Dipper and Mabel if he did not consent. Ironically, Bill's backstabbing ways left him oblivious to a double-cross from the Pines twins, resulting in his defeat.

Despite his confident nature, if Bill gets caught in a helpless situation, he'll go into a deep panic, as when Bill was tricked into entering Stan's mind and was about to be erased from existence, Bill desperately tried to bargain with Stan by offering to give him money, fame, riches, infinite power, and even his own galaxy.


  • Immortality: Bill is older than the galaxy.
  • Nigh Omniscience: Bill possesses vast knowledge of many things in existence. He is not, however, entirely omniscient, as he has been tricked multiple times in the past.
  • Interdimensional Entity Physiology: Bill is an interdimensional demon.
    • Dealing: One of Bill's most noticeable abilities is that he can make a contract with someone to give the said person who made a deal with him fame, power, or a request. Bill's hand becomes surrounded in a blue flame and, once the person exchanges a handshake, while the flame doesn't harm the person, the deal will be sealed. However, once the deal is sealed, Bill will want something in return that often ends up in his twisted methods. If the person breaks the deal, Bill's powers won't have any effects on them, as Gideon broke his deal when Bill failed to get the combination for the safe. Also, making deals is the only way Bill's powers could have an effect but only to the ones who made a deal with him.
      • Dream Walking: Living up to being called the "Dream Demon", as Bill makes a deal with someone, he can enter their dreams. He entered Stan Pines' mind to get the combination to the safe after making a deal with Gideon.
      • Possession: Another way if someone makes a deal with someone, Bill can possess a host who made a deal with him. While in the host's body, their eyes turn into Bill's.
    • Levitation: Bill can hover and float freely.
    • Reality Manipulation: Another one of Bill's most noticeable traits is his power to manipulate the laws of reality. Bill can transform organic matter, disorient the physical world, and cause a ripple in the space-time continuum. After breaking the Nightmare Realm, Bill's powers grew stronger to the point where he can manipulate reality on a cosmic scale.
    • Regeneration: Bill can repair himself if he gets injured, such as his form, his limbs, and his eye. However, he stated it takes an hour for his eye to regrow.
    • Shape-Shifting: Bill can switch his form between 2D to 3D. He can even change into a demonic form with spider-like traits.
    • Size-Alteration: Bill can grow into an enormous or gigantic size and can return to his normal size at will. He is able to increase the size of his body parts as he did with his fist.
    • Telekinesis: Bill can lift and move objects and living beings with his mind.
    • Telepathy: Bill can read a person's thoughts.
    • Gravity Manipulation: Bill's top hat changes the gravity of the Earth to whatever the angle of his hat is.
    • Soul Removal: Bill can remove a person's soul from their bodies, as he removed Dipper's soul from his body so he could possess it.
    • Body Projection: Bill can remove himself from his physical form to enter the mindscape and his physical form will become stone.
  • Master Manipulator: Another one of Bill's traits is that he is quite manipulative. Bill can flatter others, deceiving them by promising them anything. He can go as far as to make deals with them only to betray them at the end. Bill once did it with Dipper on how he sacrificed everything to make Mabel happy but never returns the favor, trapped Mabel in a dream that contains her desires, he even tricked Ford Pines and Gideon, with the former admitting he lied and the latter being a skilled deceiver himself.


Gravity Falls[]

Season 1[]

"Dreamscaperers" is the first time Bill is directly addressed and introduced in the series. Gideon Gleeful, in an attempt to take over the Mystery Shack once again, summons him. Gideon tells him to steal Stan's safe combination directly from his head so that Gideon can steal the Shack's deed. Bill immediately agrees once he pictures Stan's own tattoo, but in return, Gideon would have to help him in his own plans. We don't know what they are yet, but they might have something to do with a secret society that Stan could possibly be included in. Gideon agrees and the two shake 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 confronts the trio and brags that he knows what they're all thinking. To prove his statement, he summons Xyler and Craz from Mabel's imagination. He tricks Mabel and her two dream guys into looking for the memory of Stan's safe combination first, knowing they would lead him straight to it. At some point, Soos is separated from everyone else, and Bill takes his place. Once they find the correct memory he takes it and nearly escapes with it. But while he was reading out the combination to Gideon (whom he was connected to), Mabel shoots the memory into another memory of the Bottomless Pit with a nyarf gun. Gideon breaks off their deal to Bill's fury, and he turns his anger onto Mabel and Soos, bringing their worst nightmares to life, and killing Xyler and Craz.

Bill gets mad at Soos, Mabel, and Dipper.

Dipper returned in a timely manner and told Mabel and Soos that, while they're in Stan's mindspace, they can do whatever they want. The three battled Bill and he was nearly defeated but put a stop to everything instead. Impressed, he decided to let the three go and warned them about a mysterious darkness that will change everything, before telling them he will be watching them, leaving one last impression of the wheel that encircles him in book 2.

Season 2[]

Bill reappeared again in "Sock Opera" for the first time in season 2, when Dipper tried to figure out the password for the laptop from the former episode, "Into the Bunker". He offered the laptop's password in return for the favor he wanted, but Dipper refused the offer. Later, at the moment the laptop was on a countdown for complete data erase 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 that 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 retrieved it for Dipper. He almost swindled her out of it, but wound up in a fight with her. He ended up losing because Mabel used Dipper's physical weakness and exhaustion to her advantage. As Dipper collapsed, he was thrust out of Dipper's body. Bill possessed the Dipper puppet afterward and said that he will return. However, Mabel lit the pyrotechnics, which destroyed the puppets.

Bill briefly appears in Ford's dream during the episode "The Last Mabelcorn", warning him about the end of the world that is coming. In this episode, it is revealed that Bill originated from an alternate dimension known as the Nightmare Realm.

He appears again in "Dipper and Mabel vs. the Future", where he possessed Blendin Blandin and tricked Mabel into giving him the Interdimensional rift, which he eventually destroyed, beginning the end of the world. Bill then took on a physical form and began wreaking havoc on Gravity Falls. He trapped Mabel in an enormous bubble, melted the statue of Nathaniel Northwest, and introduced his friends, an assortment of monsters as terrifying and weird as Bill himself. After Ford Pines attempted to blast the dream demon back into his own dimension, Bill turned him into a golden statue to use as a backscratcher and destroyed the three journals.

Bill "is destroyed" by Stanley Pines

In the series finale "Weirdmageddon", Bill discovered his inability to leave Gravity Falls even after entering the real world. To find a way out, Bill tried to get into Ford's mind, but Ford refuses to let him in. After capturing the kids and coming very close to killing them, Ford caved in and let Bill into his mind in exchange for Stan and the kids' lives. Bill entered his mind only to find that Ford switched places with Stan and now Bill is in Stan's mind. Before Bill can escape, Ford started erasing Stan's Memory, causing Bill to deteriorate in glitch-like fashion inside the mindscape as Stan punched Bill right in the eye and shattered him into pieces, destroying him and forever ended his evil game.

Following his demise, everyone was free from the tapestries as Weirdmageddon immediately then winded to an end when the Henchmaniacs were forcibly sucked back into the Nightmare Realm with all the chaos, from where they came and soon the entire valley and town of Gravity Falls was restored as everything returned back to the way it was before the whole tragedy even began. Shortly after, the only thing that remained of Bill Cipher after the event was his petrified body now lying isolated somewhere within the woods.

Other appearances[]

Bill Cipher makes several cameos in DuckTales (2017), as symbols resembling him. He can be seen in a hieroglyph in "The Living Mummies of Toth-Ra!", albeit colored green. Bill also appears in the notes in Launchpad McQuack's windshield in "Beware the B.U.D.D.Y. System!". He also appears in "The Last Adventure!" as a drawing in Isabella Finch's original Junior Woodchuck Guidebook.

Bill makes a brief cameo in The Owl House episode "The Intruder" among the demons on King's "Demon 101" wall.

In the Amphibia episode "Wax Museum", several figures and silhouettes resembling Bill can be seen. A drawing of Bill also appears in the episode "True Colors" as Marcy Wu reads a book containing information about the Calamity Box.

Bill makes a cameo in the Big City Greens episode "Present Tense" as a plush toy.


Disney Fanon Wiki has a collection of images and media related to Bill Cipher.


  • He is based on the Eye of Providence which is most commonly seen on the back of an US $1 Bill.
    • He was initially going to be colored green like the dollar bill, but he resembled a leaf too much, so instead he was given a yellow color. (This lead to many jokes among the fandom about Bill resembling a Dorito, much to Hirsch's ire).
  • Alex Hirsch had initially hoped to cast Twin Peaks creator David Lynch as the voice of Bill. When he turned the project down, Hirsch decided to simply do an impression of Lynch for Bill's voice, giving him the loud nasally tone Lynch gave to the character Gordon Cole.
  • On the page about Bill in book 2, the -$12 bill says "Semper vigilantum", which in Latin means "always watching".
  • Bill mentions gold (and Stan mentions burying gold in "Boyz Crazy"). The Beale ciphers are a set of three ciphertexts, one of which allegedly states the location of a buried treasure of gold, silver, and jewels estimated to be worth over USD$63 million as of September 2011.
  • He may also be related to the Illuminati, a figure on the Mayan Calendar and subject of innumerable modern conspiracy theories.
  • It is unknown what he wanted in return from Gideon when he got the safe code from Stan's memory.
  • Both Gideon and Dipper's journals contain sections on Bill, but strangely, Gideon's journal contains instructions on how to summon Bill, whereas Dipper's contains instructions on how to stop Bill if he is summoned.
  • In the game Rumble's Revenge, one of the translated cryptograms says "I will be returning to Gravity Falls.." This foreshadows his appearance in "Dreamscaperers".
  • He unofficially appeared as a pop-cultural cameo in the Rick and Morty episode "Big Trouble in Little Sanchez". This is due to Alex Hirsch having guest-starred in this episode and being friends with Rick and Morty co-creator Justin Roiland.
  • Bill's wheel symbol makes a cameo in Disney Infinity 3.0 Edition.
  • After the credits, Bill's petrified body is mysteriously shown in real life. This later became part of the alternate reality game Cipher Hunt. The Bill Statue used for Cipher Hunt is now on display at Confusion Hill in Piercy, California, one of the roadside attractions that inspired the Mystery Shack.
  • Right before his death, there is some sort of hidden message encoded in Bill's last words which translates to: "A-X-O-L-O-T-L, MY TIME HAS COME TO BURN, I INVOKE THE ANCIENT POWER THAT I MAY RETURN!".
  • Bill Cipher was originally going to have his own Villain Song in the Weirdmageddon Arc, called It's Gonna Get Weird.
  • Bill makes a cameo in The Simpsons episode "Bart's in Jail" where the family collectively hallucinate Loki, along with his "many forms" which include Anansi, Monkey King, Jesus Christ, Huēhuecoyōtl and Bill himself who tells the Simpsons "Buy crypto, suckers!" Hirsh reprised his role for the episode.
