Dipper is 18 years old. He has dark brown hair and brown eyes. His most distinctive feature is a birthmark on his forehead in the shape of the Ursa Major constellation, which he often hides under his bangs. He wears a blue and white cap with a pine tree on it, a dark blue vest, an orange T-shirt, gray shorts, and black sneakers.

A good-natured and slightly clumsy 27-year-old handyman at the Mystery Shack. He sincerely believes in the paranormal in Gravity Falls and often becomes an indispensable assistant to Dipper and Mabel, for example, driving them around town. Despite his seemingly carefree demeanor, Soos suffers from profound psychological trauma due to his father's abandonment as a child.

Wendy is a 20-year-old redhead who works part-time at the Mystery Shack. She's quite laid-back, but also displays determination and strong athletic skills. Wendy is friendly and often supports Dipper when he's being bullied. She knows Dipper has feelings for her, but due to the age difference, she doesn't reciprocate them, maintaining a friendly relationship.

Brown eyes with cataracts. Gray hair, almost always hidden under a dark burgundy fascia. A large, drooping nose, reddish-pink, pear-shaped. Large ears. Fair skin, wrinkled due to age. Wears a hearing aid and dentures, slouches, often leans on a cane with a billiard ball for a handle, and sometimes wears an eye patch. At work, he wears a black suit with a buttoned jacket, a red bow tie, brown shoes, and a fez. At home, he wears a white T-shirt, turquoise striped boxer shorts, slippers, glasses, and a fez. On his shoulder blade, he has a burn in the shape of a symbol from the dashboard of the underground laboratory.

Dark gray hair with a horizontal silver streak at the sides. Unusually long sideburns. A chin with a Japanese and light five-o'clock shadow. A smoother nose than Stan's without bumps. Brown eyes. A narrower build than his brother. A congenital pathology - six fingers on each hand. At the beginning of the series, a large black coat with many pockets, under which a black shirt and trousers, bulky black boots, a brown shoulder belt, a shabby raincoat, and a gray scarf. Later, a shabby beige coat, a red turtleneck with a black belt, black trousers, and brown boots. A diarist.

Mabel is 18 years old. She has round, rosy cheeks and long, curly brown hair. She wears bright sweaters, skirts, headbands, white socks, and ballet flats.

Fakes and hyperreality. All the exhibits and merchandise are fake, created with glue, cunning, and Stan's love of money. He creates a hyperreality in which fantastical creatures seem real.
Caches and hidden passages. There are many hiding places in the hut: behind the painting, in the living room, in the floor, behind the vending machine.
Secret rooms. For example, Ford's room, discovered by Soos in the episode "Carpet Trick," or Dipper and Mabel's room in the attic.

Inside, the hut is multi-level with an intricate layout.
Ground floor: This contains a museum (with stuffed fantasy creatures), a gift shop, a living room (where the Pines watch TV), Stan's office (with a copy machine and fake documents), a kitchen, and a storage room.
Basement: Under the gift shop there is a door leading to the basement.
Dungeon: Behind the vending machine in the souvenir shop is an entrance to an underground laboratory with a portal to parallel worlds.
Attic (mansandra): This is where Dipper and Mabel's room is located, with arcade games, two beds, a table, and a niche for a fortune-telling machine.

Exterior. The cabin is located at 618 Gopher Road in Gravity Falls, Oregon. It has several entrances: a main entrance, a back entrance with a porch, a door leading to a room in the floor, and an entrance to the gift shop. There's a sign on the roof with the name, but the "S" in "SHACK" periodically falls off. There's also a small rooftop balcony with a cooler, where Wendy likes to hang out. The weather vane, instead of the usual letters, features "W, H, A, T" with a question mark.

To summon Bill, you need a picture of the victim. The eyes must be crossed out, and the picture must be surrounded by eight candles in a circular formation. Then the following spells should be recited: "Triangulum, entangulum. Veneforis dominus ventium. Veneforis venetisarium!" Your eyes will turn blue. The sky will turn gray. Next, you must repeat the phrase "Zhdesem Sadrovkab" five times in a row. A triangle will appear, an eye will open, and it will transform into Bill.

An interesting aspect of Bill Cipher is that, despite being a villain, he's always honest and keeps his word, even if his actions are not. Even in his physical form, he never destroyed Gravity Falls in an instant. Even in his physical form, he never caused any harm to the world—Weirdmageddon laid the groundwork for a fair fight between Bill, a threat to the world, and the Pines family, who had already provided him with the opportunity to become a threat. Only when everyone succumbed to their selfishness did Bill manage to win and save Gravity Falls—Mabel abandoned her magical world, where she was happy. Gideon refused to be the demon's assistant and sided with the Pines family.

"I don't think a single night cuckoo is worth all the mysteries of the universe. And then there's your sister—how many times have you sacrificed yours for her, and has she ever done the same for you?" Bill's line from the same episode, where he directly confronted Dipper with his sister's selfish behavior and thus pushed him to make a deal. Dipper knew it was dangerous, that he was putting everyone close to him, including himself, in danger. But he made it anyway—the selfishness inside him had awakened and clouded his judgment.

Almost every time Bill appears, selfishness awakens in all the heroes, which results in unpleasant consequences for them.

When he appeared to Mabel in Blendin's body, even though she didn't know it was Bill, the selfishness within her awakened and clouded her judgment—she'd given up the dimensional rift and unknowingly triggered Weirdmageddon—she was desperate. And Bill took advantage of it.

Bill came to Stanford when he was desperately searching for the source of all the anomalies in the town and was helpless. Thanks to a spell cast by Ford, Bill awakened the egoism within the young and trusting scientist, which he used to lead Ford to build a bridge between the three-dimensional world and the Nightmare Realm—a Universal "Portal"—thereby laying the foundation for his entry into the human world and his "liberation."

Bill appeared to Dipper as he desperately tried to crack the password to the laptop containing the author's information. The demon offered him a deal in which he would give the boy a clue (he kept his end of the bargain, by the way). He convinced the boy that his sister was being condescending toward him and everyone else, and that she shouldn't help with her play, as he had important things to do, too. These words clouded Dipper's judgment, and his selfishness awakened—he made a deal with the demon, knowing it was wrong and that the consequences could be disastrous.

Bill most frequently appears throughout the series when the characters are in dire straits. Bill appeared to Stanford in a dream after he, desperate for information about the source of the anomalies, cast a forbidden spell to summon a demon. Bill appeared to Dipper twice in "Sock Opera," when the boy was desperately trying to crack the laptop password and obtain information about its author. Bill appeared to Mabel at the end of "Dipper and Mabel vs. the Future," when she was devastated over being left alone before her birthday.
Every time he appears, Bill offers to help the characters and manipulates them to achieve his goals. The funny thing is that despite being a villain who can't be trusted, Bill has always been honest, even during Weirdmageddon, and in almost all of his appearances to the heroes, he's been right in his statements:
"Think about it, who would be willing to sacrifice everything for some stupid sister or brother?" Bill said in "Sock Opera," threatening to ruin Mabel's performance if she didn't give him the diary. He was right—Mabel had repeatedly acted selfishly toward others throughout the series, even if she didn't realize it due to her age. It was this line from Bill that prompted Mabel to reflect on her behavior and improve in the future. Perhaps she simply ended up in the MAV-3L dimension in the "Forgotten Legends" comic, which takes place after the end of Weirdmageddon and before the twins' departure home, because in "Sock Opera," Mabel first began to doubt whether she was truly so kind to those close to her, and she realized her mistakes from the outside and her own—all thanks to Bill.

Bill is a sensible, eccentric, and insane demon. He's incredibly strange and charismatic, and speaks very quickly. He's not to be underestimated: when enraged, he possesses a power beyond reckoning (as Gideon teased him about his deer teeth). Psychologically speaking (his wisdom teeth), Bill is truly insane; he knows he's insane, but he considers it an asset, a cunning device he uses reliably to achieve his goals.

He masterfully manipulates his enemies and adversaries ( Blendin , Stanford , and especially Dipper ). While he almost always tells them the truth, he twists the words or gives them a different meaning.

Bill isn't one to follow rules. He considers legal and physical laws meaningless and displays an irresistible desire to break them. He has his own selfish philosophy: "Do what you want and don't worry about the consequences."

When Bill managed to inhabit Dipper's body, he hurt himself in various ways, not out of masochistic inclinations, but because he found inflicting pain on someone else's body "fun." However, Bill has little understanding of human physical limitations, so sometimes this backfires.

Eventually, he conquered and transformed into a lair for himself and his minions the swirling, ever-shifting intergalactic froth between dimensions: a lawless, unstable space between worlds known as the Nightmare Realm (also known as "Dimension 0"). Having perpetrated his rampage for millions of years, he earned a reputation as one of the most feared beings in the entire multiverse.

Unfortunately, due to the absence of any laws in the Nightmare Realm, including the laws of physics, it was doomed to self-destruction sooner or later. So Bill searched for ways to escape until, a million years before the events of the saga, he learned of a prophecy that he would merge the Nightmare Realm with the Earth dimension.

He began manipulating countless people across eras, attempting to use them to create a portal to achieve this goal and become a physical being. However, he failed time and again.

Bill was born more than a trillion years before the events of the saga. He hailed from a two-dimensional universe known as Euclid. When he was born, he had Velcro shoes that squeaked when he ran, and everyone loved him.

The mayor declared Bill's birthday a national holiday. On his birthday, Bill gave everyone free knives as gifts. Despite this, however, Bill despised life there, describing it as a dimension of "flat minds in a flat world with flat dreams." He had a mutation that gave him an abnormally large eye, allowing him to see into the third dimension. This gave him the ability to see a direction known as "up," something the rest of his dimension's inhabitants could not.

Even though talking about a "third" dimension was illegal in his world, Billu couldn't think of anything else but the possibility of joining it. Despite boasting about his good life, during a drunken tirade he hinted that his claims of a happy childhood were false and that he had in fact been ostracized due to his mutation, which gave him the impetus to finally make his race understand what he had witnessed. In an event known as the "Euclid Massacre," he "liberated" his dimension, plunging it into blazing chaos along with everyone he had ever known, including his own parents. Perhaps due to the psychological trauma of this event, he is unable to fully recount the details of the massacre (whenever he tries, a loud roar echoes in his ears and he loses consciousness). Given this, it remains unclear whether he ever intended to commit this act. All that is known is that this was the only act that Bill truly regretted and undoubtedly missed his lost home.

Bill's words from his diary: "Listen, I know you want to hear a tragic story that humanizes me and softens my edges, but you won't find anything! The truth is, I've always been admired!"

Pale skin, bright yellow eyes, one eye hidden by a patch for beauty, yellow, fluffy, soft hair. Yellow suit with a white shirt and a black bow. On his head is a small black top hat. Black pants and black shoes. Wears white gloves. Narcissistic, but rarely, VERY RARELY, is he kind.
