Sans AUs

Dream Sans: 500+ years old, wears a golden circlet on his skull. Sports a golden-yellow cape (often with a sun symbol), a light blue or withered yellow-and-cyan coat, and matching boots. Features a golden belt marked with the initials "DS" (Dream Sans), sometimes accompanied by small bells or a front badge. Uses a golden staff that can transform into a bow for shooting positive energy arrows. He can be overly talkative and dramatic when worrying that bad things might happen. He actively tries to calm down conflicts and fill alternate universes with love and happiness.

Ink Sans: Has no age but considered 1000+ years old, his pupils change colors and shapes (such as a blue circle and a yellow star) depending on his current mood or the paint he processes, with an ink blot usually smeared on his right cheek. He wears a light shirt with a protector strap, a blue-and-brown sleeved jacket or shirt layer, light brown shorts, and sport shoes with tiger prints. A massive brown scarf wrapped around his neck (used to jot down quick memory notes) and a cross-body work belt loaded with heart-topped vials of rainbow paint.Weapon: He carries a gigantic, lightweight magical paintbrush named "Broomie" strapped to his back. Soulless and technically emotionless on his own, he drinks from his paint vials to artificially simulate feelings like joy or surprise. Extremely forgetful, he writes notes directly onto his giant scarf and has a habit of accidentally vomiting black ink when overly excited or stressed. Childish, witty, and a lover of pranks, but can come across as blunt, provocative, or detached in his social interactions. Deeply passionate about art and creation, he acts as a protector of alternate universes while dreading empty, colorless spaces.

Swap Sans: Wears a dark grey or grayish battle-body shirt with a white undershirt. Sports a bright blue scarf or cape around his neck. Equipped with dark blue pants and matching blue boots. Features expressive light blue eyes and can move his mouth and eyebrows. Acts flamboyant, loud, and very excited all the time. Calls himself the "Magnificent Sans" or "Supreme Sans". Loves cooking Mexican food like tacos and burritos instead of Italian spaghetti. Enjoys telling jokes and puns, but loves doing riddles and puzzles.

Nightmare Sans: Also 500+ years old and considered Dream's brother. Covered entirely in a sticky, negative, dark blue/black goo or slime that drips constantly. His skeletal structure is obscured by the darkness, usually showing a single glowing blue or cyan/purple light or eye expression through the goo. Possesses four to six fluid, shadowy tentacles emerging from his back that he uses for combat, movement, and intimidation. Typically wears a dark, tattered version of his past royal/guardian clothing or a jacket, often featuring a crescent moon motif depending on the design variant. He relishes causing emotional and physical pain, feeding directly off the negative energy of others. Rather than just using brute force, he prefers to exploit psychological weaknesses, taunt his enemies, and use their own memories or flaws against them. Consumed by past trauma and hatred from his village days, he lacks mercy and acts as a destructive force across the multiverse. Originally, he was exceptionally kind, empathetic, and protective, making his current malicious demeanor a tragic complete inversion of who he used to be.

Killer Sans: His eye sockets are completely empty, with black liquid (overloaded determination) constantly leaking from them. He wears a darker blue unzipped jacket with a very fluffy white hood, a black turtleneck instead of a white shirt, white shorts with black stripes, and blue shoes with white tips. His soul is permanently visible outside his chest, shaped like an upside-down human-monster hybrid soul that often resembles a red target or bullseye. He often acts playful, chaotic, and sarcastic on the surface, treating violence like a dark game or performance while masking inner instability. He suffers from suppressed feelings, deep dependency on a purpose or master (like Nightmare Sans), and occasional bursts of hidden guilt or fear. First State: He is approachable and more like classic Sans, though burdened by guilt. Second State: His emotions fade, making him unpredictable and dangerous to anyone nearby. Third State ("Crazy Mode"): He becomes entirely emotionless and violently attacks anything in his path.

Dust Sans: He wears his classic blue hooded jacket over a white t-shirt, black shorts with white linings, and gray or pink slippers. His clothes and frame are caked in the literal "dust" of the monsters and friends he has slaughtered to gain power. He often pulls his jacket's hood up to keep the dust from getting onto his face. While his eyes are normally white pupils, during combat or emotional spikes, his left eye glows cyan and red, while his right eye glows a bright red. Driven mad by the guilt of killing everyone in the Underground—including his own brother Papyrus—he has lost his original lazy and comedic demeanor. He suffers from constant auditory and visual hallucinations, vividly seeing and talking to the floating, glowing skull and scarf of the deceased Papyrus. Despite his madness, he remains hyper-rational and single-minded about his ultimate goal: gaining enough LOVE (level of violence) to permanently stop the human from resetting the timeline. He views his horrific actions as a necessary evil, believing that murdering the rest of the Underground himself is the only way to save everyone from endless suffering.

Horror Sans: He features a massive, jagged hole on the left side of his skull caused by Undyne. His normal glowing blue eye is replaced with a dark socket featuring a permanent, eerie red light or a red artificial eye. He wears a tattered, furry dark blue hoodie stained with old blood, paired with a stained white undershirt and sturdy sneakers instead of his classic slippers. He frequently carries a massive, blood-stained bone-axe used for both intimidation and close-range combat. Years of famine and a broken psyche left him desensitized to violence, often enjoying dark or psychological humor. Beneath his feral and threatening exterior, he is deeply tired and secretly tries to protect remaining townspeople and his brother from total starvation. His mind struggles to process complex thoughts smoothly, causing him to shift unpredictably between lethargic boredom, sudden aggression, and fleeting traces of his old, jocular self.

Cross Sans: Cross has one white pupil and one red pupil, alongside a red, lightning-bolt-shaped scar under his right eye socket from a fight against XTale Frisk. He wears a black long-sleeved shirt under a prominent white hooded jacket with furry trim, black shorts, and white shoes marked with "X" designs. His soul is uniquely split—half white monster soul and half red human soul. He wields large knives, a hack knife, and twin daggers. Cross carries heavy trauma and sadness over the destruction of his universe, making him obsessed with restoring his lost family and friends. He is generally introverted, distrustful, and aggressive toward strangers, shifting from a lawful royal guardsman to a chaotic code thief out of desperation to save his world. Though he can be harsh, he cares deeply for his original universe's companions, which makes him vulnerable to manipulation by entities like Nightmare.

Error Sans: He is a black skeleton with red or dark bones, covered in glowing glitching pixels, error symbols, and floating text boxes. He wears a dark jacket or cloak that shifts from black to blue with a blue hood, black pants with blue vertical stripes, and dark slippers or shoes. Blue "tear" marks run down from his eye sockets. His right eye is white, while his left eye glows blue with a thick yellow ring and a black pupil. His teeth and fingertips are a distinct yellowish color. He works as a self-appointed destroyer of alternate universes, believing only the original game should exist. Because his body constantly glitches, his moods shift wildly from calm or nerdy interests (like crafting or chocolate) to explosive rage. He suffers from a severe fear of being touched (haphephobia) and harbors a profound, hidden loneliness due to living in an empty anti-void.

Classic Sans: A short and somewhat thick-boned or paunchy skeleton with mitten-like hands. An unzipped blue hoodie with a gray hood, a white t-shirt or tank top underneath, black shorts with white vertical stripes, and a pair of casual slippers. Features a wide, permanent toothy smile and white glowing dot pupils inside dark eye sockets. His white pupils vanish when he becomes serious or angry, and his left eye flashes bright cyan (light blue) and yellow during powerful telekinetic attacks. Often found sleeping on the job or taking shortcuts, which stems from an apathy tied to knowing timeline resets erase all progress. Loves telling terrible, skeleton-themed puns and playing pranks, and enjoys drinking ketchup. Deeply cares for his brother Papyrus and friends, quietly reading people's expressions and past choices. Shifts from a friendly slacker into a formidable, grim judge during critical moments or when pushed onto a destructive path.

Fell Sans: He wears a black unzipped jacket or coat (often with a fluffy or spiky hood), a red shirt or turtleneck sweater underneath, black shorts with red or yellow stripes, and red sneakers or slippers. He is a short skeleton with sharp, pointed teeth (including a distinct gold tooth) and constant red eye-bags from exhaustion. His left eye socket frequently glows a bright red and yellow/orange to reflect his emotional stress and inner turmoil. Raised in a brutal "kill-or-be-killed" world, he tries to act cool, tough, and collected, though he carries heavy emotional stress. He dislikes bad puns (preferring knock-knock jokes instead) and comes across as sarcastic, tired, and harsh. He has a strange fondness for drinking mustard and eating relish. Unlike the easygoing bond in the original game, he lives in fear of or deep friction with his brother, Papyrus, who treats him harshly and forces him to work as a human hunter.

Lust Sans: Wears a purple unzipped jacket with blue fluff, a crop-top featuring a blue heart motif, low-rise black jeans exposing his hip bones, and blue boots with black gloves. Drawn with purple pupils—often shifting into a pink or purple heart shape when excited, emotional, or aroused. Designed with a slimmer, more refined skeleton frame compared to classic Sans. Extremely flirtatious, seductive, and constantly seeking affection, validation, or romantic attention. Beneath his overt behavior, he harbors deep self-awareness and depression driven by a profound hatred for the tragic, broken state of the Underground. Acts out of a coping mechanism for the heavy trauma and systemic despair defining his universe.

Epic Sans: Wears a black and purple long-tailed trench coat with a Half-Soul (upside-down heart) design and a white ribbon on the back, alongside a turtleneck or hoodie. Sports black fingerless or open-fingered gloves and black striped pants tucked into boots. Has a prominent scar over his left eye socket, which normally looks empty. A glowing purple magical eye appears in his scarred socket when he feels stressed, focuses deeply, or tries to intimidate someone. He frequently uses the word "bruh" in casual conversation and loves sharing jokes or meme-related humor, especially around his best friend Cross from XTale. While he acts lazy, casual, and goofy like classic Sans, he is highly intelligent and skilled as a royal scientist. When serious matters arise, he drops his joking facade to show uncharacteristic maturity, fighting intensely for his friends and holding deep grudges against any betrayals. Underneath his cool exterior, he can turn into an extreme nerd regarding specific interests like anime or deep lore.

Color Sans: Wears a long blue jacket, a beige turtleneck with a dark slash mark, beige gloves, blue-hemmed capri shorts, beige socks, and pink slipper-like shoes. Features a fractured skull on the right side where rainbow flames erupt instead of normal dust, and his remaining eye has a white pupil with a rainbow iris. The rainbow flames grow and burn like real fire during extreme emotions (like joy, anger, or hatred) and smooth out when he is calm. Retains much of Classic Sans's original laid-back demeanor, but is more honest with himself and open-minded. Experiences heightened emotional traits tied to the six human souls he absorbed, causing him to get angered more easily. Embraces an optimistic yet nihilistic outlook on life and the multiverse after surviving his timeline's breakdown.

Fresh Sans: Wears a pink polo shirt, a multicolored unzipped sweater (blue, purple, orange, and white), green-and-blue pants with a yellow zipper, and white-and-pink Heelies. Sports a red backwards cap with a cyan propeller and opaque black sunglasses that display changing words like "YOLO" or "RAD" based on his current thoughts. Removes his glasses when distressed or fighting, revealing a multi-armed purple parasitic creature with a sharp-toothed mouth and a single eye inside the host's eye socket. Acts like an extreme, hyper-positive 90s stereotype who hates swearing (automatically censoring bad words into slang) and calls everyone "brah" or "broseph". Lacks the capacity to feel normal emotions or care about others, driven primarily by a parasitic survival instinct and a fear of being exposed or beaten. Constantly ignores social boundaries, touches people uncomfortably close, and loves to annoy entities like Error Sans.

Ccino Sans: He often sports a soft, casual cardigan or sweater and comfortable café attire, fitting his role as a barista. His overall design leans into a warm, fluffy, and gentle aesthetic compared to the sharp or edgy looks of other fandom variants. He is almost always depicted surrounded by or interacting with small, fluffy cats that resemble other versions of Sans. He is a friendly, polite, and welcoming host to everyone who visits his shop. He cares deeply for his cats, which help bring life and joy to his daily routine. Beneath his cheerful and warm exterior as a café owner, he is lowkey sad or depressed, often masking his true negative feelings to avoid burdening others or facing rejection.
