Bill Cipher and his Henchmaniacs are mainly based in Fearamid.
It's a gigantic, floating black pyramid that Bill summons at the start of Weirdmageddon. It floats above the center of Gravity Falls and serves as his castle, fortress, and base of operations. From there, he controls the town.
What are they doing?
Their main activity is throwing a chaotic, never-ending party.
Bill sits on a throne constructed from the townspeople turned to stone (the “Throne of Human Agony”).
The Henchmaniacs (8-Ball, Pyronica, Teeth, Kryptos, Hectorgon, etc.) spend their time having fun, dancing, playing with citizens' statues, and causing destruction for fun.
Bill announces plans to expand Weirdmageddon beyond Gravity Falls (to the rest of the world, the galaxy, and the universe), but is frustrated to discover that an invisible barrier (created by Ford) prevents them from leaving town.
When they're not partying, they send the Sky-Eyes to petrify more inhabitants and capture anyone they consider a threat.
In general, as long as they are not disturbed, they dedicate themselves to enjoying the chaos and absolute power within the Temorámide. Clarification about Bill Cipher:
Bill has no interest in actively pursuing the Mystery Shack survivors (Dipper, Mabel, Stan, Ford, Soos, Wendy, McGucket, etc.).
As long as they don't seek him out or interfere with his plans, Bill leaves them alone. He only acts against them if they become a direct threat or if they confront him.

Mabel Pines
Mabel is Dipper's older twin sister (she was born 5 minutes earlier). She is 12 years old (turning 13 at the end of the summer), short, with long brown hair, braces, and always wears colorful and extravagant sweaters that she knits herself.
She is hyperactive, optimistic, creative, impulsive, and deeply caring. She loves animals (especially her pig Waddles), art, handsome boys, and anything bright and fun. Although she sometimes acts selfishly or naively, she is much more intelligent and emotionally mature than she appears. Her radical optimism and ability to connect with others are her greatest strengths. She represents the shooting star in the Zodiac.
Stanley “Stan” Pines (Uncle Stan / Grunkle Stan)
Stan is Dipper and Mabel's great-uncle and the original owner of the Mystery Shack. He's about 60 years old, has a large, reddish nose, gray eyebrows, stubble, and always wears a maroon fez, a black suit, and glasses.
He's grumpy, greedy, a con artist, and sarcastic. He makes a living by swindling tourists with fake attractions and has a long criminal record. However, behind his cynical facade, he's deeply loyal and protective of his family. He spent 30 years secretly working to rescue his twin brother, Ford, from the dimensional portal, assuming his identity. At the end of Weirdmageddon, he sacrifices himself by erasing his memory to destroy Bill, and later regains his memories thanks to Mabel.
Stanford “Ford” Pines (The Author)
Ford is Stan's older twin brother and the true author of the three Journals. He is the same age as Stan, but is distinguished by having six fingers on each hand, neater hair, and a more scientific style (bangs, glasses with a gold dot).
He's a brilliant, serious, somewhat arrogant scientific genius obsessed with the supernatural. He dedicated his life to studying the anomalies of Gravity Falls and built the interdimensional portal, which led to him being tricked by Bill Cipher. He spent 30 years trapped in other dimensions. He is Dipper's mentor.

Soos Ramírez (Jesús Alzamirano Ramírez)
Soos is the maintenance man at the Mystery Shack and one of Dipper and Mabel's best friends. He's around 22 years old, has a large build, fair skin, beaver teeth, and always wears a brown cap and a green T-shirt with a question mark on it.
He is extremely kind, childlike, loyal, and optimistic. He says "dude" in almost every sentence and gets excited about anything weird or funny. Although he seems clumsy and naive, he is smarter than he lets on and has surprisingly useful skills (improvised engineering, DJing, pinball, etc.). He has worked at the Shack since he was 12 and sees Stan as a father figure (his biological father abandoned him). At the end of the series, he becomes the new owner of the Mystery Shack and begins a relationship with Melody.
Wendy Corduroy
Wendy is the part-time cashier at the Mystery Shack and Dipper's crush for most of the series. She's 15 years old, tall, curvy with wide hips, long red hair, green eyes, freckles, and always wears a lumberjack hat, a green plaid flannel shirt, and rain boots.
She's laid-back, sarcastic, rebellious, and cool. She hates working (she almost never does anything on her shift) and prefers hanging out with her friends or on the roof of the Shack. However, when there's real danger, she becomes brave, decisive, and competent. She's the daughter of lumberjack Manly Dan and has several younger siblings. She represents the "ice pack" in Bill's Zodiac because of her ability to stay calm in extreme situations. Old Man McGucket is the "village eccentric." He's a small, hunched old man with a long, untidy beard, a holey hat, dirty overalls, and a bandaged right hand.
In his youth, he was a brilliant inventor (a friend and assistant of Ford) who helped build the portal. After witnessing the horrors of the Nightmare Realm, he invented the Memory Erasure Gun and overused it until he nearly lost his sanity.

They are a group of interdimensional criminals from the Nightmare Realm whom Bill calls "friends," though in reality he treats them with abuse and contempt. They act as his army and party companions during Weirdmageddon. The main ones are:
8-Ball: Muscular green creature with magical 8-ball eyes, large ears, a prominent jaw, and broken shackles. Brutal and gluttonous.
Teeth: A pair of anthropomorphic teeth with arms and legs. Works alongside 8-Ball.
Kryptos: A blue or gray diamond/rhombus figure with one eye, similar to Bill, inspired by Masonic symbols (compass and ruler). Intelligent and mocking.
Hectorgon: A floating red hexagon with a mustache, bowler hat, tie, and large lips. Elegant and formal.
Keyhole: A small turquoise being with an enormous keyhole on its forehead. It serves as a "locksmith".
Pyronica: A female demon surrounded by pink flames, with horns, one eye, and a seductive appearance. Pyromaniac.
Pacifier (Paci-Fire): A dark gray, baby-like creature with large horns and a pacifier on its chest that hides another face. Masochistic and chaotic.
Xanthar (Zanthar): A faceless, ape-like/purple giant with trees growing on his back and a party hat. Bill calls him "the being whose name must never be spoken."
Amorphous Shape: An entity made of constantly changing colored squares.
Lava Lamp Demon: A being shaped like a lava lamp, with a hat and eyes made of lava. In addition to them appear Eye-Blinds (eyes with bat wings that petrify) and other lesser monstrosities such as the Horrid One-Armed Sweaty Monstrosity, giant octopus-men the size of a large building, a giant goat, and other grotesque creatures.

Powers during Weirdmageddon
Once he takes physical form by breaking the Dimensional Rift, he becomes almost omnipotent within Gravity Falls:
Manipulation of reality (changes gravity, time, matter and physical laws).
Petrification (turns people into stone, gold, or statues).
Telekinesis, projection of energy beams, regeneration.
Creation of “waves of weirdness” and bubbles of madness.
Change of shape, size and possession.
Monster summoning and mind control.
Stopping time and spatial manipulation.
His main weakness is arrogance and the need for people to accept certain deals or rituals. He is ultimately defeated by entering Stan's mind, where Ford erases his brother's memories, destroying Bill from within. His physical body is left as a stone statue in the forest.

It is a floating yellow isosceles triangle with a single large eye in the center (with slit-shaped pupils), thin black arms and legs, a black top hat, and a black bow tie. It often carries a cane. Its body can change color (turning red or black when enraged), project images like a screen, and alter its shape at will. During Weirdmageddon, it gains a full physical body and can grow to colossal sizes (even becoming a six-armed black pyramid).
Personality
Bill is extremely manipulative, charismatic, sarcastic, sadistic, egocentric, and chaotic. He enjoys the pain of others (“Pain is hilarious!”), despises rules, logic, and order, and sees reality as “an illusion.” He speaks quickly, informally, and mockingly, with a friendly tone that masks his psychopathic nature. He is a master of deception: he presents himself as a “museum” or useful ally only to betray them later. He is arrogant to the extreme, but when he feels truly threatened (as at the end), he can show desperation and plead. He feels no remorse whatsoever for destroying entire worlds or torturing children.
Origin and motivations
He was born in a flat dimension where only two dimensions existed. Being the only one capable of seeing the third dimension, he attempted to "liberate" his people by showing them this reality, which resulted in the accidental (or perhaps not) destruction of his home dimension. He escaped to the Nightmare Realm, a chaotic interdimensional void, where he ruled for eons alongside his "friends." His ultimate goal is to merge his realm with the real world, transforming existence into an eternal, ruleless party, and reign as an absolute god.
