Bad Gays and Star Sanses.

Character

Error isn't just "evil Sans," but an unstable anomaly with a clear, albeit frightening, logic. His core belief is that the multiverse is rife with errors, and he is the tool that erases them. He doesn't enjoy this, but rather sees it as a necessity: as if he were cutting out the infected area to prevent the entire system from collapsing.

He lacks empathy in the conventional sense, but he does have strange principles: he can spare a universe if he "aesthetically pleases" it or finds it structurally important. At the same time, he hates chaos without form—for example, he considers Fresh!Sansa one of the worst anomalies precisely for her meaningless noise.

He's mentally unstable: his emotions cause him to "glitch," and in those moments, he loses control. He has a phobia—haptophobia (fear of being touched): if someone touches him without asking, he reacts harshly and aggressively. He's also nearsighted, so he wears glasses (given to him by Alphys when he was still Geno in Aftertale). And for all his destructive role, he has some tiny human habits: for example, he loves chocolate. At the end of his mission, he plans to self-destruct—it's part of his logic: if he's a mistake, he must be erased.
Appearance

In canon, Error appears as a skeleton, seemingly "falling apart into pieces of code." His bones are dark, almost black, with red accents and "Error" markings that aren't just decoration, but part of a glitch—they appear and disappear when he's unstable. Blue threads extend from his eye sockets—his primary weapon and instrument of control: he uses them to bind souls, transport them, or even transfer his consciousness to another body.
His eyes are asymmetrical: one pupil is white, the other is yellow-blue, and the whites are red. Due to his poor eyesight, he sometimes wears round glasses with red frames, but more often he relies on threads. Text artifacts almost always flicker around him—lines of code, error symbols, which literally "pour" out of him when he's under strong emotion.

Character

Horror is Sans, broken by the cruel necessity of surviving in a world where kindness quickly becomes weakness. He's pragmatic to the point of cynicism and accustomed to solving problems in the most "reliable" way—quickly, harshly, and without unnecessary drama. Yet his cruelty isn't driven by pleasure: he does what he considers inevitable, and the longer he lives in this world, the harder each choice becomes.

He still has a dark sense of humor, but now it's more of a defensive reaction: he jokes to keep from going crazy, not to make people laugh. He dislikes empty promises and doesn't throw words around: if he says "I'll cover you," he means it, even if it costs him his strength. Despite his fearsome reputation, he protects those he considers "his" in his own way—primarily Papyrus—and is capable of doing things for his brother that go against his own rules. Another important trait: he tries not to show how tired he is, because weakness in his world is an invitation to disaster.
Appearance

Horror's appearance underscores the trauma he's endured. His skull bears a large, noticeable crack—the mark of a severe injury, which makes his appearance even more sinister. One eye is either missing or replaced by something unnatural: often depicted as a black void with a bright red pupil, as if blazing with cold rage.

He wears a tattered blue sweatshirt or jacket that once looked like Sans's regular clothes, but is now covered in stains, scuffs, and small rips. Underneath, he wears a plain white T-shirt, also not particularly clean. His shorts, with white stripes down the sides, look almost like a relic from a previous life: they're too "ordinary" for what he's become. Instead of soft slippers, he wears sturdy blue sneakers, as if he's long since given up on leisurely strolls.

Character

Blue is all about sincerity, a little awkwardness, and a huge desire to be helpful, even if it's not always the best. He's energetic, talkative, and always eager to cheer everyone up: if someone is sad, Blue will be the first to rush in with a joke, a cookie, or an offer to play some silly game. He's not a fake-happy guy, though: he has moments when he freezes and quietly says something profoundly serious—and it's in those moments that you can really tell how much he's going through.

He tries to avoid fights if they can be resolved verbally or without conflict at all: violence weighs heavily on him, and the sight of others' pain makes him cringe. But if someone close to him is in real danger, he'll stand in their way, even if he's shaking with fear. He has a habit of planning everything, but his plans always fall apart due to his impulsiveness: "I wanted to do everything carefully, but then I just ran." He also loves small acts of kindness: discreetly adjusting a scarf, bringing someone hot chocolate, remembering someone's favorite phrase and inserting it into a conversation to make them smile.

view

Blue's palette is vibrant blue, as if crafted from the palest shades of the sky. He most often wears dark blue pants and a jacket with brown accents, topped with a deep blue scarf that has become his signature detail: he sometimes wraps it three times, sometimes casually drapes it over his shoulder, or even ties it like a bandana. His gloves and boots are also blue, but a slightly darker shade to blend in with the rest of his outfit.
His eye glows with a soft blue light, and sometimes there's a slight "glitch" in it—as if reality were momentarily tripping over his emotion. His bones are slightly lighter than classic Sans's, and seem coated with a fine, frosty texture, like frost on glass. There's always something jingling on his belt or in his pockets: keys, keychains, small jars (they can contain anything from spices to "lucky dust"), and a saxophone case often dangles from his side—he loves music and sometimes pulls out his instrument when he needs to distract someone.

Character

Ink is about creativity, chaos, and the desperate desire to keep universes from fading. He's hyperactive, talkative, and loves to tease, but not out of malice—more to stir things up. He has a short memory, so he's always writing things down on his scarf: names, promises, jokes, important thoughts—otherwise he'll simply forget them. He's full of mischief and childishness, but underneath it all lies a deep anxiety: he's terrified of emptiness, whiteness, and oblivion—anything that erases color and meaning.

Ink isn't just a cheerful artist: he has his own mission—to support creativity and protect universes from total annihilation. He doesn't interfere with other people's timelines with orders, but he's willing to stand in the way of anyone who wants to erase everything. He sincerely believes that even a small drawing or line of text can save the world. And while he often acts frivolously, in critical moments he becomes focused and stern: if necessary, he'll stand between a threat and a fragile universe, even if it costs him his paint. Another trait is that he loves to inspire others: he can literally "paint" someone's resolve, encourage them with a ridiculous joke, or give them a brush with the words, "Here, make something beautiful." Appearance

Ink looks like an artist who just ran out of his studio and forgot to put on shoes: he walks barefoot, as if it's easier for him to feel the ground (or ink). His outfit is composed of elements reminiscent of an artist's attire: a white tank top, a brown jacket over it, and overalls tucked into his belt underneath. He wears light green gloves, similar to those used for tablet computers.

The main feature is paint everywhere: splashes, brushstrokes, streaks on clothes and bones, as if he's constantly in the process. Small paint bottles hang from his belt, their heart-shaped lids hinting at the fact that he's distilling his emotions into colors. On his back is a huge brush dripping with ink; it looks both like a tool and a weapon.

Character

Dust is about fatigue, grief, and a quiet, almost imperceptible cruelty that comes not from malice, but from hopelessness. He's been through so many cycles and deaths that he's almost completely lost the feeling of pain—but he remembers very well how others feel pain. Because of this, he often maintains a distance: he doesn't want to get attached, lest he lose someone later. He's neither a hero nor a villain: he simply does what he thinks is right, even if it hurts. At the same time, there's a hidden caring quality within him—it manifests not in warm words, but in actions: he can silently cover for someone, lend a shoulder, remove a threat, and then walk away as if nothing ever happened. He suffers from a severe internal conflict: he hates what he's become, but sees no way to stop. He rarely gets angry openly - more often he is cold, calculating, and real rage breaks out only when someone touches those whom he even slightly considers “his own” Appearance

Dust's appearance is as if he were composed of dust and ash. His bones are coated in a layer of gray dust that crumbles with sudden movements, and in places, deep cracks are visible, as if he is falling apart from the inside. His clothing is simple and tattered: a dark sweatshirt or hooded jacket, the sleeves rolled up or torn, the fabric seems faded and grayed with time. Small objects often hang from his belt or in his pockets—shards of glass, scraps of paper, sometimes something like amulets or simply things that remind him of the past. His eye glows with a dim, muted light—not bright like Killer's, but more like a smoldering ember; sometimes the color fluctuates between yellow-orange and pale red. Around him, there is almost always a light haze of dust particles that slowly swirls in the air. His posture is often slightly hunched, as if he bears the weight of all his decisions; Even when he is calm, one can sense in him the readiness to rush into battle at any moment or, on the contrary, disappear into the shadows.

Character

A killer is a creature of cold determination and a habit of relying only on himself. He acts quickly, speaks briefly, and wastes no words on explanations: if he needs to strike, he strikes; if he needs to escape, he escapes. He has a lot of aggression, but it's not chaotic: it's anger, tailored to the task at hand. He views the world as a battlefield where anyone can become an enemy, so he truly trusts almost no one. At the same time, he has his own very strict moral code: he won't touch anyone who is weaker and poses no threat, and if someone has earned even a tiny shred of trust, he will defend them to the end, even if it means pretending not to care. He often hides his emotions behind rudeness and sarcasm, and when the going gets tough, he becomes frighteningly calm—at such moments, he's extremely collected and dangerous.

Appearance

Hitman looks like he's just gotten out of a fight and isn't looking to stop. His outfit is a mix of practicality and dark style: most often a black or dark gray hooded sweatshirt (the hood is almost always pulled down), over which is a short jacket or vest with pockets where he stashes small items. He wears fingerless gloves to keep his hands out of the way, and knives, hooks, or other melee-like tools are often dangling from his belt or pockets. His bones are darker than usual, and in places they appear scratched or cracked, as if he's taken many blows. His most distinctive feature is his eye: it's bright red and glowing, and the pupil sometimes appears as a thin slit, like that of a predator. A subtle shadow or dark particles are often drawn around it, as if the darkness itself is trailing behind him. Killer's posture is always "on edge": his shoulders are slightly raised, his body is leaning forward, as if he is ready at any second to either rush forward or jump back.

Character

Nightmare is the embodiment of darkness and pain: he feeds on the negative emotions of others, leaving little room for softness. He is cynical, blunt to the point of cruelty, and sees no point in empty talk: if something can be solved by force or intimidation, he will choose it. Yet he is not chaotic: he has his own logic and clear goals, and he knows how to calculate his moves, as if playing a long game. He treats those who try to oppose him with cold interest—sometimes even respecting their courage—but this doesn't stop him from breaking them. With "his own" (like the Bad Guys), he is tough, unsentimental: for him, loyalty is tested by deeds, not words. And for all his terrifying nature, he has a strange trait: he remembers every emotion he has absorbed, and sometimes these alien feelings break through, causing him to break down or freeze for a second, as if he himself is being washed over by a wave of someone else's pain.

Appearance

Nightmare's appearance is the dark opposite of Dream. His bones are black, as if covered in cracks from which a thick darkness oozes, like smoke or ink. Instead of a normal eye, there's a pulsating purple-black void, flickering with the echoes of others' fears; around it, thin "tentacles" of shadow are often visible, appearing and then disappearing. His clothing is minimalist and somber: most often, it's a torn dark cape or cloak with jagged edges, as if scorched along the contours, or simply dark layers of fabric without unnecessary detail. On his chest is a symbol resembling a cracked heart or a funnel sucking in light. A subtle darkness always swirls around him, reacting to his emotions: if he's angry, it thickens and reaches out to those around him. His posture is relaxed, yet threatening: it’s as if he’s in no hurry, because he’s sure there’s nowhere to run anyway.

Character

Dream is about light, hope, and immense inner responsibility: he literally carries the power of positive emotions within himself, and this is both powerful and difficult for him. He strives to be kind to everyone, even to those who clearly don't deserve it, because he believes that something good can be found in everyone. At the same time, he's not naive: he knows that evil is real and is ready to fight if necessary, but he does so without pleasure—for him, victory is not important as a triumph, but as a means of protection. He has the trait of an "eternal older brother": he will gently guide, encourage, and sometimes be a little protective, but never push. He is also very patient and a good listener—even when the other person is angry or talking nonsense, Dream tries not to brush it off, but to understand. And despite all his "brightness," he has moments of fatigue: when emotions inside become too intense, he retreats into silence, so as not to harm anyone with a surge of power. Appearance

Dream most often looks like Sans, but with distinctly lighter accents. His clothing is usually neutral—a simple sweatshirt or jacket—but his palette always includes warm tones: cream, gold, light yellow, and white. On his chest is a distinctive symbol: a stylized sun, a star, or a glowing heart (this varies from artwork to artwork). His main distinguishing feature is his right eye: it glows with a soft gold or white light, as if a small star were burning inside; sometimes, subtle rays or "sparks" are visible around the pupil. His left eye socket is often covered with something like an eye patch or simply left dark to emphasize the contrast. His bones appear slightly lighter than those of regular Sans, as if illuminated from within, and he almost always has a subtle aura of tiny gold particles that slowly rise upward. His posture is relaxed yet collected: he's not tense, but always ready to step forward if someone needs help.

Character

Cross is a mixture of stubbornness, pain, and an attempt to cling to the remnants of himself. Due to XGaster's influence and constant rewriting, he has become harsh and distrustful: first he hits, then (maybe) asks questions. But beneath this armor hides the same Sans who doesn't want to hurt without reason: he's angry at the system, at XGaster, at his own weakness, and he lashes out at everyone. He has a clear line: to protect those he considers "his own," even if it means being rude. He dislikes pompous speeches, speaks briefly and often sarcastically, but if someone is truly in trouble, he won't leave. Another trait: he clings to little things that remind him of his former life (habits, jokes, details), as if they are preventing him from completely "erasing." Appearance

Cross typically wears a black and red color scheme: a black hoodie with rolled-up sleeves and a bright red symbol on his chest, resembling a stylized heart or crack. He wears an eyepatch (or a dark stripe, like a shadow) over his right eye, while his left eye glows red, the pupil occasionally "shaking" like a glitch. His bones are slightly darker than usual, as if covered in a fine network of cracks or digital static. He wears black fingerless gloves, and on his belt hangs a pair of small gadgets or code fragments (this is played out differently in different artworks). His posture is always slightly tense, as if he's ready to either fight or flee at any second.
