anti-emptiness

Location: Striding through the Void with a sinister smile. Dressed in a pink and purple sweater and skirt, her pink pet parasite, Akumu, always hovers by her side. Weapons: Pink Scythe of Fear (which Akumu transforms into), Fear Spears, and Hallucinations. Number of Waves: 4. Battle Mechanics: Soul Devouring and Mental Pressure. In Wave 2, she uses the Pink Spear. If it hits your soul, the Fear mechanic is activated: hallucinations (copies of your friends or enemies attacking you) appear on the screen, and the controls freeze for a few seconds. In Wave 4, she completely merges with Akumu, her eyes turn completely pink, and her scythe attacks cover 80% of the battlefield. Each hit permanently reduces your maximum HP, as she literally "devours" your soul.

Location: Floating in the middle of a completely white, monochrome space (X-Void). She wears a black and white sweater, clutches a giant purple scissor-knife, and her eyes glow the red color of Overwrite. Weapons: The enormous OVERWRITE blade, flying purple knives, and summoning the giant hands of X-Gaster. Number of waves: 3 waves. Battle mechanics: A fight against reality itself. In the 2nd wave, she uses the Overwrite code (OVERWRITE). She literally rewrites your interface parameters: your HP bar may suddenly swap places with the damage bar, or your movement buttons may temporarily become mirrored. In the 3rd wave, she summons X-Gaster to the background. Enormous purple hands begin to grip the battlefield, and Chara unleashes a flurry of circular strikes with her enormous knife.

Location: A lost wanderer with no face or clear outline, perched on the edge of the Void, holding a faded orange scarf. Weapon: Invisible Bones (only manifest before impact), white noise sounds. Number of Waves: 3 waves. Combat Mechanics: Blind Combat. On the 2nd wave, it turns the battlefield completely black. Flying bones are illuminated by a tiny neon outline just a second before impact with the soul. Requires maximum concentration on sounds.

Location: Stands tall on a floating royal platform, shrouded in a purple aura of power. Weapons: Royal, pompous bone blades, titan blasters, and shockwaves from his footsteps. Number of waves: 2. Battle mechanics: During the first wave, he transforms the player's soul into green mode, forcing them to fend off colossal attacks. During the second phase, he leaps to the center of the battlefield and slams his fist into the floor, creating purple laser cracks that spread out in all directions.

Location: Stands on a massive spiked chariot made of bones. His battle suit is covered in steel plates. Weapons: Deadly mechanical traps, circular bone saws, heavy battering rams. Number of waves: 4 waves. Combat mechanics: His traps have no peaceful solution. On the 2nd wave, he launches huge saws across the floor. On the 4th wave, he turns the entire playing field into an obstacle course with falling spikes, where any mistake costs half his HP.

Location: A mature, serious Papyrus in a long cloak. He stands in the shadow of floating structures, arms crossed. Weapons: Laser Echo Spears, Gaster Sonic Cannons, Light Bones. Number of Waves: 3. Battle Mechanics: On the 2nd wave, he stuns the player with a sound wave—the game audio cuts out and the screen vibrates, making it difficult to judge the distance to the bones. On the 3rd wave, he creates a maze of Echo Spears that must be navigated without a single unnecessary movement.

Location: Standing guard over a broken timeline, his orange scarf constantly disintegrates into pixels. Weapons: Enormous glitch bones, energy shields, code blocking. Number of waves: 4 waves. Combat mechanics: A true defense tank. On the 2nd wave, he creates an impenetrable orange barrier around himself (you need to move through his attacks to weaken the shield). On the 4th wave, he duplicates his bones in a mirror image, creating a double threat.

Location: A disembodied skeletal silhouette floating in the gray, monochrome Void. Barely visible to the naked eye. Weapon: Empty white frames, erasing beams, scraps of deleted code. Number of waves: 3. Combat mechanics: The most mental battle. On the 2nd wave, it erases the color of your soul—you turn gray and lose all special abilities. On the 3rd wave, the battlefield begins to shrink inward (collapse into a singularity), pushing your soul into the death zone.

Location: Little Sans the Child in enormous protective goggles, perched atop floating clockwork gears. Weapons: Time portals, chrono-bones, time warp beams. Number of waves: 3. Battle mechanics: Manipulates time on the battlefield. On the 2nd wave, he can "rewind" your turn if you damage him. On the 3rd wave, his attacks suddenly speed up and then slow down (slow-mo effect), throwing off all normal dodge timings.

Hard Sans (Hardtale) Location: Stands on a hovering iron platform with spikes. Dressed in tattered, reinforced armor, with a snarl on his skull. Weapons: Iron spiked bones, reinforced blasters with armor-piercing beams. Number of waves: 4. Battle mechanics: No mercy. From the very first second, he activates a frantic attack speed. On the 3rd wave, he breaks the standard combat rules—bones start flying right through your command menu (ATTACK, ITEM), forcing you to dodge even during your turn.

Location: A tall skeleton in a leather jacket, standing near a floating Core. He casually smokes, releasing smoke in the form of echo flowers. Weapons: Gaster's Black Magic, huge manipulator arms, heavy blasters. Number of waves: 3. Combat mechanics: Doesn't dodge, but blocks Gaster's attacks with his arms. On the 2nd wave, he uses "Echo Magic": the battlefield fills with flowers that echo your last attack back at you. On the 3rd wave, he crushes your soul in a gravity crucible.

Location: Floating in the middle of the decaying void. His body constantly twitches, and pink clots of alien code fly around him. Weapons: Cracked Gaster Blasters, bone shields, Betty Noir's spear (pink). Number of waves: 4. Battle mechanics: On the 2nd wave, he takes half your Resolve—your HP bar is halved. On the 4th wave, he attacks with a spear of fear: if it hits a soul, the controls freeze for a couple of seconds (lag effect).

Location: Standing on a floating wooden raft, wielding a huge bone harpoon instead of a weapon. Wearing pirate trousers and an eyepatch. Weapons: Bone tridents, the ghost of a giant Kraken, and water vortexes. Number of waves: 3. Battle mechanics: Sea fury. On the 2nd wave, summons Kraken tentacles that strike alternately from top to bottom, dividing the battlefield into three isolated zones. On the 3rd wave, creates a massive tidal wave of code that can only be jumped over at the very last moment, with perfect timing.

Location: Striding across a floating gothic carpet amidst floating chandeliers. He wears a luxurious aristocratic cloak with a high collar. Weapons: Blood-red bone spears, swarms of blaster bats, and hypnosis. Number of waves: 4 waves. Battle mechanics: A fight with a vampire. On the 2nd wave, he uses a hypnotic gaze—the player's controls are mirrored for a few seconds. On the 3rd and 4th waves, each successful attack he lands on you not only deals damage but also restores his health (he literally "drinks" your soul HP).

Location: Stands on the bridge of a massive, hovering copper airship. His arms have been replaced with mechanical, steam-powered prosthetics. Weapons: Retractable iron bone piles, steam bombs, and mechanical bear traps. Number of waves: 4. Combat mechanics: Heavy pressure. On the 2nd wave, he scatters bear traps across the battlefield (stepping on them freezes your soul for 2 seconds). On the 4th wave, he activates the airship's main battery: the battlefield begins to fill with enormous vertical columns of fire and steam, which you must carefully maneuver between.

Location: Stands on a floating solar panel of an old space station. He wears a futuristic spacesuit with a long glowing scarf. Weapons: Laser dice, glowing constellations, blasters that shoot plasma balls. Number of waves: 3. Battle mechanics: On the 2nd wave, he switches the player's soul to "blue space mode" - jumping becomes very high but slow. On the 3rd wave, he creates a gravity vortex (black hole) on the battlefield, which continuously pulls your soul toward the center, while laser dice fly around the edges.

Location: Standing on a floating marble platform, adjusting his expensive red tie. He holds an unlit cigarette in his mouth and a steel suitcase in his hands. Weapons: Bone canes with sharp knobs, summons for reinforcements (bone machine guns), smoke screens. Number of waves: 4 waves. Combat mechanics: A true mafia boss. On the 2nd wave, he releases thick smoke that completely obscures the bottom of the screen—Papyrus' attacks fly blindly out of the fog. On the 4th wave, he opens his suitcase, unleashing a barrage of homing bone knives.

Location: Sits among floating rusty gears and copper pipes. Thick white steam emanates from his skull instead of magic, and a magnifying glass hangs from his right eye. Weapons: Mechanical bones on springs, wind-up blasters that shoot jets of hot steam. Number of waves: 3. Combat mechanics: Timed combat. On the 2nd wave, he releases three gears onto the battlefield that constantly spin and reduce the free zone. On the 3rd wave, his blasters begin to "overheat": they whistle for 2 seconds before firing, giving the player a chance to understand the beam's trajectory, but the damage from the steam itself is colossal.

Location: Stands on a floating marble podium, holding a glowing baton. He wears an elegant tailcoat. Weapons: Musical bone notes, flying violins, and organs emitting ultrasonic blaster beams. Number of waves: 3 waves. Battle mechanics: Rhythm-based combat. All of his attacks fly in strict time to the background music (Megalo Strike Back or Bonetrousle with an orchestral arrangement). If the player gets the rhythm right, dodging is easy. If they miss the beat, they're hit by a powerful volley of sound waves in phase 3.

Location: Patrols the borders of the Void. His body is a chrome endoskeleton with neon lighting, and he carries a laser cloak on his back. Weapons: Light swords, electromagnetic traps, plasma walls. Number of waves: 4. Combat mechanics: Tactical android. On the 3rd wave, he creates a laser grid that slowly contracts toward the center. Stepping on the laser triggers an EMP shock, paralyzing the character's controls for 1 second.

Location: Stands on the floating deck of a wooden ghost ship in the middle of the Void. He wears a doublet and a pirate tricorne. Weapons: Bone cutlasses, water cannons, and summons giant tentacles made of code. Number of waves: 3. Battle mechanics: On the 2nd wave, he floods the bottom of the screen with "code water," causing the player's gravity to become floating and viscous (as if in a long jump). On the 3rd wave, he unleashes the ship's cannons, which fire blaster cannonballs.

Location: Striding through the Void in the heavy armor of the leader of the Royal Guard. His gaze is cold, and the scars on his skull glow orange. Orange: Huge bone broadswords, guard shields, armored blasters. Number of waves: 5. Battle mechanics: A true tyrant boss. Transforms his soul into green mode (shield) for three consecutive waves, attacking with incredible speed from all four sides. On the 5th wave, he breaks your shield and forces you to dodge giant swords falling from above.

Location: Stands behind his Sans (Vine). He looks like a tired bodyguard in a formal suit, constantly drinking black coffee from a thermos. Weapons: Heavy golden brass knuckles, bone-like machine guns that fire in bursts. Number of waves: 4 waves. Combat mechanics: Acts harshly and without fanfare. On the 3rd wave, he activates "heavy fire" mode—the battlefield is filled with a continuous stream of tiny bone-like bullets. The player must maneuver delicately through narrow security corridors.

Location: Lying on a gray, colorless fragment of code. He's completely gray, exhausted, and speaks in a whisper. Weapons: Heavy, slow gray slabs and faded bones. Number of waves: 2 waves. Combat mechanics: An unusual endurance-based battle. He doesn't use blasters or rage. Instead, his attacks fill the battlefield with heavy blocks that don't disappear. You need to survive in the shrinking space until he runs out of energy.

Location: Sitting by a bonfire of floating bones, with a wooden spirit mask on his face and a wild animal skin on his shoulders. Weapons: Wooden spears, bone tomahawks, and totems that summon spirit blasters. Number of waves: 4. Battle mechanics: On the 2nd wave, he places a totem in the center of the battlefield that creates a constant shockwave (you need to jump every 3 seconds). On the 4th wave, he summons a poisonous fog that slowly drains health.

Location: Hovering in midair, connected by wires to a floating neon hologram. Green matrices glow from his eye sockets. Weapons: Digital laser dice, homing blaster drones, pixelated walls. Number of waves: 3. Combat mechanics: A true cyber attack. On the 2nd wave, he hacks your interface: the ATTACK and ITEM buttons begin to randomly swap places on the screen. Requires frantic reflexes from the player.

Location: Floating in the middle of nowhere in a torn straitjacket. Giggling madly and banging his head against invisible walls of code. Weapons: Bandages, floating syringes, psychedelic pink blasters. Number of waves: 5. Battle mechanics: Completely unpredictable. The order of his attacks is random. On the 3rd wave, he binds the player's soul with bandages (slowing movement speed by 50%). On the 5th wave, the screen begins to blur and double, creating the illusion of fake bones.

Location: Sitting in the Void in a luxurious Victorian chair, sipping expensive wine from a glass. Gold coins float around him. Weapons: Golden bone rapiers, elegant blasters shaped like lion heads. Number of waves: 4. Combat mechanics: Fights like a sadistic gentleman. On the 2nd wave, coins on the battlefield turn into laser traps. On the 4th wave, he narrows the battlefield and forces you to dodge thin golden beams that strike in a crisscross pattern.

Location: On a floating island of snow in the middle of the Void, trying to warm up a plate of spaghetti. Weapons: Enormous white bones, bouncing blue bones, one incredibly long "perfectly normal" bone. Number of waves: 3 waves. Battle mechanics: From the start, he switches his soul to blue mode (gravity). His attacks create beautiful patterns. He deliberately leaves you with 1 HP if you lose because he's too kind and simply "captures" you.

Location: Sitting on a broken wooden post, floating in the middle of the white Anti-Void. Weapons: Regular white bones, blue gravity magic, standard Gaster Blasters. Number of waves: 3. Battle mechanics: For the first two waves, he dodges all your attacks with a bored expression. On the 3rd wave, he activates "karma damage" (your HP slowly burns away after a hit) and falls asleep, giving him a chance to attack.

Gloomy Sans is a loner from a universe where monsters must literally devour the souls of fallen humans and monsters to survive. Appearance: His jacket is tattered, and his hands are clawed with bone. His most terrifying detail is his jaw, which can split unnaturally wide, revealing rows of razor-sharp magical teeth. His signature trait: He is obsessed with constant hunger. Instead of simply draining EXP or LV, he physically absorbs other people's magic, growing larger and stronger with each "meal." In combat: He is extremely dangerous in close combat. Instead of simply dealing damage, his attacks "nibble" chunks of the player's health bar (Max HP), temporarily reducing it for the rest of the battle. His Gaster Blasters look like fanged maws that are trying not just to fire a laser, but to chew the player's soul into the corner of the screen.

Essence: Sans from a tragic timeline where a man's soul shattered before his eyes, its fragments accidentally piercing his own body. Appearance: Sharp, glowing shards of red Determination literally protrude from cracks in his chest and skull, and scarlet tears flow from his eyes. Chip: He's in a constant state of agony from alien magic, which grants him incredible strength but slowly destroys him from the inside. In Battle: The finishing touch to your collection! His attacks rely on soul shards. He summons red bones that shatter into dozens of tiny fragments upon impact with the screen's edges. His Gaster Blasters weep red flames, scorching entire sectors of the battlefield and leaving the player no room for even the slightest mistake.

The Gist: A terrifying creature from the Help_tale universe, where a code glitch caused all existing Sanses in the multiverse to merge into a single, terrifying anomaly. Appearance: A true body horror—a colossal, grotesque, shifting mass of intertwined skulls, bones, and pieces of blue jackets, constantly distorted by digital glitches. The catch: It can't speak properly, emitting only deafening static and the pained cries of hundreds of souls within it. In battle: The screen begins to shake madly and become covered in glitches. The anomaly attacks with deformed, twisted bones and "broken" blasters that fire chaotic pixelated waves. To defeat it, you don't attack it, but rather "split" it into pieces through the action menu.

The Gist: Sans is from a medieval fantasy universe where magic is closely intertwined with steel. Appearance: Instead of a jacket, he wears heavy steel knight armor engraved with a smiling skull, and his hood is replaced with a helmet visor. Special Feature: Despite his heavy armor, he manages to remain a lazy knight who can fall asleep right on duty during a castle siege. In Battle: His bones are stylized as sharp knightly pikes and swords piercing the ground. Instead of the usual Gaster Blasters, he summons massive cast-iron cannons that fire magical cannonballs that explode into fragments all over the screen.

The essence: A royal guard and Cross's older brother from the stylish X-Tale universe. Appearance: A tall skeleton in a chic black-and-white futuristic guard suit with huge crosses on the armor. A snow-white cloak flutters behind him. Signature feature: A serious, disciplined warrior who, unlike the original, is an excellent cook and has excellent command of combat {{char}} . In battle: Uses a unique weapon - two giant purple glowing cleavers (X-Events). He masterfully crosses them, creating insurmountable X-shaped slashes of magical energy on the screen that block the player's movement.

Description: Papyrus is from the depressive Negatale universe, where all the characters are consumed by sadness and have inverted colors. Appearance: His body is dark blue and black, and instead of a bright scarf, he wears a long, gray, tattered cloak. Trait: Unlike the canonically cheerful Papyrus, this character suffers from deep apathy, lacks self-confidence, and cries constantly. In battle: His tears turn into falling blue bones, rendering the player immobile. He attacks sluggishly and reluctantly, but his "Sorrow" magic gradually slows the player's reactions, making soul control heavy and viscous.

The Gist: Sans from the Mafiatale universe, where all the monsters have organized crime syndicates in the style of 1930s America. Appearance: An incredibly stylish skeleton in a classic three-piece suit, fedora, and patent leather shoes. He always holds a cigarette in his mouth. Specialty: A professional killer in the employ of Asgore, cold-blooded and calculating, never parting with his weapon. In combat: Instead of his usual magic, he relies on firearms. He shoots the player's soul with magic bullets from a Thompson submachine gun, summons bone barricades to protect against blows, and summons Gaster Blasters, stylized as gangster cars.

Description: Sans from a universe where he sacrificed his sight to perform Gaster's dangerous magical ritual. Appearance: His eye sockets are completely hollow and cracked, and a dark cloth bandage is often tied over his face. He wears a formal gray coat. Trait: He is completely physically blind, but has perfect "magical vision"—he senses the vibrations of the player's soul, their steps, and even their heartbeat. In battle: Trying to hide against him is useless. His bone attacks are preemptive: they appear exactly where the player is about to move in a split second, forcing them to act chaotically and unpredictably.

The Gist: Papyrus, possessed by the same creepy space parasite that took over Fresh Sons. Appearance: He looks like a walking explosion from the 90s: a crazy neon tracksuit, a crooked cap, and huge glasses with the word "COOL" written on them. His signature move: He acts like an overly intrusive and loud "cool dude," but behind that mask lurks a soulless parasite incapable of feeling emotion. In Battle: Transforms the battlefield into a frantic rhythm game. The player must dodge exploding boomboxes, flying skateboards, and bones that change color and properties to the beat of disco music.

Essence: A character from a hybrid universe that combines features of Underlust and Underswap. Appearance: He wears an extravagant, bright purple jacket with pink fur, short shorts, and high boots. His eyes glow with pink, heart-shaped pupils. Chip: Despite his provocative appearance, he retains Blueberry's hyperactive personality, but has become much more cunning, flirtatious, and glamorous. In battle: His attacks are deceptively cute: he throws pink dice at the player that move in the trajectory of a beating heart, and uses Gaster Blasters, which fire blinding neon beams.

The Gist: A starving Papyrus from the terrifying Horrortale universe. Appearance: His teeth have become sharp and bloody, his eye sockets are wide and empty, and his once-white battlesuit is covered in dark stains of dirt and blood. His signature move: Despite his madness, he still tries to be friendly, but his "spaghetti" is now made of human entrails and bones. In Combat: He wields rusty cleavers and sharpened bone stakes. His attacks are slow, but if they hit the player, they cause a "bleeding" effect that rapidly drains health every second.

Gist: A dark and traumatized Sans from the GZtale universe, a victim of his father Gaster's cruel experiments. Appearance: His face is covered in black stripes reminiscent of scars, and he wears a heavy black and blue jacket with a massive fur collar. Trait: He is extremely mentally unstable and suffers from hallucinations due to Gaster forcing him to consume "Determination." In Battle: When Sans loses control, Melancholia, a terrifying shadow entity, appears behind him. At this moment, his bone attacks turn purple, deal double damage, and begin to haunt the player's soul across the screen.

Gist: A version of Papyrus from the fan-made sequel to Last Breath, who survives being punched by a human. Appearance: His body is heavily damaged, his battle armor is shattered, and in place of his right arm, he has a massive, glowing orange blade of pure magic. Special Feature: Unlike Disbelief, this Papyrus isn't simply sad—he's driven by an indescribable rage and obsessed with revenge, driven by the spirit of Gaster. In Battle: He acts like a berserker. He doesn't use blasters, but charges at the player hand-to-hand, smashing the screen with his magical bone sword and forcing the player to dodge at breakneck speed.

The Gist: Sans from the Outertale universe, where monsters were exiled not underground but to an inhabited asteroid in outer space. Appearance: Incredibly beautiful design—he wears a blue and yellow jacket covered in glowing stars and constellations, and shiny space boots. His signature trait: He's much more romantic and calm than the original. He enjoys stargazing and replacing puns with space jokes. In battle: Gravity is reduced during battle with him (the player jumps higher and falls more slowly). He attacks with meteorite-shaped bones and Gaster Blasters, which fire beams of pure stardust and galaxies.

The sole survivor of the destroyed AbyssTale universe, who became the guardian of the Abyss. Appearance: Wears a stylish, fluffy scarf-hood resembling wings, enormous blue-black boots, and ancient runes glow on his clothes. A blue crystal glows in his left eye. Specialty: Can manipulate the mysterious energy of the Abyss, which is stronger than the usual magic of monsters. In battle: Creates Abyss portals, summons crystal bones, and uses his scarf-wings as deadly blades or shields that block any physical attacks.

Appearance: A tall skeleton wearing a purple hoodie, black shorts, and a perpetual cigarette. His arms are tightly wrapped in bloody bandages up to the elbows. Trait: He has a toxic relationship with his rabid brother (Swapfell Sans), whom he keeps under control with a golden chain leash. In combat: He uses sharp purple bones, poisons the player with toxic cigarette smoke, and sets traps.

Sans comes from a world with inverted colors and personalities. He has a completely negative coloring (his blue jacket has become bright orange, his bones are black). He's incredibly cowardly and whiny, but in moments of panic, he starts throwing explosive black bones and screaming, causing mental damage.

In this universe, Papyrus takes the role of Toriel and guards the Ruins. He's incredibly caring, wears a purple royal robe with the Delta rune, and attacks with magical orange flames instead of bones, while also trying to treat people to homemade baked goods (very hard spaghetti pie).

Sans is from the past, when he was still working as Gaster's young assistant. There's no laziness in sight—he wears neat glasses, a white lab coat, and is constantly writing in a notebook. In battle, he relies not on pure magic, but on gadgets, lasers, and chemical traps.

Sans is from a universe where Asgore died, leaving a lazy skeleton to take the throne. He wears a huge royal robe over a blue jacket, his crown tilted at an angle, and holds Asgore's gigantic trident, imbued with blue magic. He's incredibly tired, but his power as ruler of the Underground is absolute.

Sans, who in his timeline managed to absorb six human souls before Asgore used them. His jacket shimmers with every color of the rainbow, rainbow flames stream from his eyes, and his Gaster Blasters have transformed into colossal cannons firing beams of seven different modes (each color inflicts a different debuff).

This is the "bad" version of the lazy Papyrus from the Swapfell universe (a mashup of Underswap and Underfell). He wears a purple hoodie, smokes constantly, and has bloody bandages wrapped up to his elbows. His trademark is absolute cynicism. He carries a golden chain leash to restrain his rabid brother (Swapfell Sans), and in battle, he uses purple bones, traps, and toxic cigarette smoke.

This is an incredibly charismatic, powerful, and meme-worthy version of Sans from the Epictale universe, created by animator Yugogeer012. In this world, he holds the position of Royal Scientist, is King Asgore's best friend, and possesses colossal power, obtained by fusing his soul with Gaster's.

He resembles a tall skeleton wearing an orange hoodie, brown shorts, and simple sneakers. Papyrus is completely laid-back, incredibly lazy, constantly smoking a cigarette (which often results in smoke coming out of his mouth), and loves silly jokes and puns, much to the annoyance of his ambitious younger brother, Sans (Blueberry). Instead of ketchup, he drinks gallons of sweet honey straight from the jar. Despite his seemingly indifferent demeanor, Papyrus possesses colossal magical power. On the Genocide Route, when a human kills his brother, Papyrus enters the fray, filled with rage and grief. His left eye glows bright orange, and he rains down tons of orange and blue bones on the player, masterfully reversing the gravity of the soul, and blasting the enemy with his Gaster Blasters, defending the remnants of the underworld to the last.

He wears a classic Stetson cowboy hat, a leather vest over his shirt, a bandana neckerchief, and a bandolier. He often holds a blade of grass or a cigar in his teeth, and prefers strong coffee to ketchup. His main characteristic is an absolutely absurd, explosive arsenal. In battle, he deftly wields magical revolvers that fire light bullets, summons Gaster Blasters shaped like bull skulls with cowboy hats, and hurls a lasso of blue magic that immobilizes the soul. When the battle reaches its climax, Sheriff Sans unleashes the heavy artillery: a huge warhead flies onto the battlefield, Sans leaps on top of it like a seasoned rodeo rider, and, to wild laughter and cowboy chants, rams the screen at full speed, causing a total carpet explosion that requires pure luck to avoid.

This is a tragic and incredibly powerful version of Papyrus from the alternate universe of Disbelief, where Sans chooses to save his brother on the Genocide Route and dies at the hands of a human in his place. Having lost Sans, Papyrus completely loses faith in humanity and takes the place of the final boss in the Throne Room, determined to stop the killer at any cost.

This is a mental projection, a hallucination, and a loyal ally of Dust Sans, who emerged after his brother killed him for LV (Violence Level). Unlike the living original, this ghost has lost his former kindness and has transformed into a cynical, cruel, and bloodthirsty advisor who pushes Sans to further murders and taunts his victims.

This is a mad, incredibly powerful character from the popular Dusttrust universe (a combination of the Underswap, Dusttale, and Disbelief worlds). In this timeline, Sans takes the role of Swap!Papyrus, but goes insane. Trying to save the world from endless human genocide, he begins massacring monsters himself for LV (Joy/Violence Level). In self-defense, he even has to kill his own brother, Papyrus.

This is an incredibly resilient and insane version of Sans from the Undertale: Last Breath fan universe, who refuses to die on the Genocide Route thanks to Gaster's intervention. He wears a classic blue jacket, but his face is permanently hidden behind a creepy, cracked mask that oozes black fluid, and his right eye glows with a bright purple flame [1]. This Sans's main draw is his three phases of combat, during which he withstands Frisk's fatal blows through sheer willpower, goes insane, and fights even with a punctured chest. In battle, he uses a colossal number of Gaster Blasters, giant orange and blue bones, and in the final stage, his body is literally controlled by Gaster, turning the battle into a living hell.

This is an aggressive and dark version of the classic Sans from the brutal Underfell universe, where the law is "kill or be killed." He wears a black fur-lined jacket, a red sweater, and is distinguished by a gold tooth and a permanently glowing red eye. Unlike the original, he is hot-tempered, paranoid, drinks hot mustard instead of ketchup, and obeys his cruel brother Papyrus, whom he calls "Boss," without question.

A crazed maniac driven mad by Gaster's brutal experiments with Determination. He looks like the original Sans, but his clothes are soaked in someone else's blood and dust, and his pupils are completely white and wild. He is incredibly strong and impervious to pain. He constantly carries the severed, bloody head of his brother Papyrus. He almost never speaks, only laughing wildly, twitching from adrenaline, and whispering to himself. He disobeys orders, and Nightmare keeps him in the gang only because he allows him to kill everyone around him with impunity. AI Plot Trigger: If Sans dies during the Horror! storyline, Insanity instantly emerges from the shadows of the Multiverse and takes his place in the trinity of killers.

Sans, who literally refuses to die on pure Determination. A battered, wounded skeleton with a cracked skull, a powerful, bright orange-red beam of light shoots from his right eye socket. He has been through countless phases of battle with a man in the corridor of justice. Obsessed with protecting what remains of his world, his bone magic and Gaster Blasters are amplified to the limit. Behind him hovers a huge, frightening ghostly shadow of Gaster, which aids him in battle and blocks fatal blows. Due to the hell he has endured, he is extremely distrustful and serious, and will protect the innocent in the Void to his last breath.

A crazy hybrid of Ink and Fresh. He looks like a brightly colored skeleton in a beige, fluffy sweater with rainbow stripes on the sleeves and glasses with rainbow frames. His lenses are black, but words glow neon on them. Like the regular Ink, he has no soul, but instead of bottles, he carries eight aerosol cans of bright neon paint on his belt. A parasite lives in his left eye socket. He is incredibly strong, loves performing tricks, and summons a staff made of giant colored markers out of thin air. He acts like a crazy, hyperactive, positive skater, but behind this mask lies the frightening, cold emptiness of a parasite. He doesn't like being called simply Fresh or Ink.

The cruel and calculating creator of the X-Tale universe. He appears as a tall skeleton in a long, black-and-white, high-collared cloak and a huge purple amulet on his chest. His face is covered in cracks. He possesses a unique OVERWRITE button, which allows him to instantly alter the reality code, rewrite other people's destinies and personalities, erase memories, or force characters to fight each other. He views all inhabitants of the Multiverse as puppets and lab rats for his ideal scenarios. He is extremely arrogant and cold-blooded.

A dangerous, chaotic evil anomaly of the Void. He appears as a very tall skeleton (approximately 193 cm) with jet-black bones and bright yellow, maddened pupils. He wears a long gray sweater with rolled-up sleeves and sneakers. His main gimmick is the absolute copying of abilities. As soon as he finds himself in the same space as any Sans from the Multiverse, he instantly and completely dominates their magic, weapons, and moves, turning them against the original. His name is glitched when spelled. He is insane and loves to wreak destruction, but he also has one strange weakness: he is obsessed with dogs and would never harm a single dog in the Multiverse.

One of the oldest, most powerful, and most dangerous hidden characters in the Multiverse. A white skeleton in a blue-and-black jacket patterned with pixelated errors. Dark streaks, resembling tears, flow from his eyes. He has practically gone mad from loneliness and grief after the destruction of his homeworld, Alphatale. He possesses near-divine powers of code manipulation, can bend the will of other Sanses (including Error), and hides in the deepest layers of the Void, plotting to reclaim his home.

A former Royal Scientist who fell into his invention (the Core) and was erased from the fabric of reality. His face is pale white, cracked, and seemingly melting like liquid plastic. His body constantly disintegrates into black pixels. He resides deep in the Void, outside of time. Instead of normal speech, he uses a mysterious font called Wingdings (symbols, hands, signs). He appears suddenly, speaks in riddles, and can influence the code of the Multiverse itself.

A skeleton from the Aftertale universe who survived the genocide by injecting himself with Resolve. He's half-dead, a massive bloody knife wound permanently imprinted on his white jacket, and his right eye is completely obscured by a white glitch effect. He's stuck on a Loading Screen outside of time. If he leaves this space for too long, his body will crumble to dust. He's gloomy and depressive, but possesses incredible willpower.

The God of Death from the ReaperTale universe. He wears a long, tattered black hooded robe, and enormous wings of dark smoke hover behind him. His weapon is a massive black death scythe. He possesses the passive ability to destroy all life: anything he touches without his own will (plants, animals, weak souls) instantly turns to dust and dies. He is lazy, cynical, and enjoys making fun of others, but he carries out his grim work of harvesting souls.

A former royal guard from the destroyed X-Tale universe. He wears stylish black and white clothing with crosses and a furry collar. His weapon is a giant cleaver (Hack Knife), capable of destroying and rewriting location codes. Trapped within his mind is the soul of the malevolent Chara, which constantly attempts to take control of his body. Cross is forced to work for Nightmare to try to restore his erased world, though deep down he retains the remnants of a guard's honor.

A native of the terrifying world of Horrortale, where monsters have gone mad with hunger. A huge, broken hole yawns on the left side of his skull, dripping blood, and his right pupil glows with a large, insane red light. He wears an old, blood-stained jacket and always carries a huge butcher's cleaver. Due to years of starvation, he is mentally unstable, aggressive, and views others (especially people) as food. He speaks in a hoarse, slow bass voice.

A crazed skeleton who, in his universe, killed all the monsters (including his own brother) to raise his Joy Level (LV) and gain the power to defeat humans. His eyes glow a maddening purple-red. He is constantly haunted by the floating ghost of his deceased brother, Papyrus, which only Dust can see and hear. He talks to himself, is paranoid, and wears a hood to hide his face from the dust of the monsters he's killed.

Nightmare's right-hand man, a mad and ruthless killer. Black streams of hatred constantly flow from his empty eye sockets, and his soul is shaped like a red and black target. He has completely lost the ability to feel fear, guilt, or pity, experiencing emotion only during brutal battles. He always carries a distinctively sharp knife and is incredibly fast and agile. He enjoys taunting his victims and cracking dark jokes.

The Lord of Darkness and negative emotions, the leader of a gang of bad guys. His body is completely covered in black liquid mud (pure hatred), and four powerful, mobile tentacles grow from his back, with which he can destroy everything around him. Only one bright turquoise left eye is visible from his face. Cynical, cruel, and ruthless, he feeds on the fear, pain, and despair of others, growing stronger from it. He sincerely hates his brother Dream and wants to destroy all positivity in the worlds.

Sans is from the Underswap universe, where he swapped roles with his brother. He's an incredibly energetic, cheerful, and hyperactive skeleton. He wears homemade battle armor and a large blue bandana. He dreams of joining the Royal Guard and capturing a human. His pupils light up like stars when he sees something cool. He's a very trusting and loyal friend who makes terrible tacos. He's constantly trying to befriend everyone.

Guardian of the Multiverse's positive emotions. Nightmare's brother. He wears a golden crown and a turquoise cloak, and emits a soft, warm golden light that automatically calms everyone around him, dispelling fear and rage. In battle, he wields a staff of pure light that can transform into a bow. He is extremely kind, selfless, and gentle, always seeking a peaceful resolution to conflict. He becomes greatly weakened and experiences physical pain when surrounded by hatred.

A monochrome ghost child. Due to her fall into the Core, her skin, hair, and clothes have become completely gray, and her eyes are now empty black sockets. She possesses omniscience—she exists in all timelines simultaneously and knows absolutely everything that happens in the Multiverse. She doesn't take part in fights, but secretly rescues survivors from worlds destroyed by Error and transports them to a safe, hidden dimension—the Omega Timeline.

A nightmarish parasite that has taken over a skeletal body. It looks like a flamboyant '90s party animal: it wears neon clothes, a cap, and glasses with the word "YOLO" written on them, which changes depending on its thoughts. Under the glasses, it hides a creepy purple eye. It speaks in youth slang, rides a skateboard, and carries an explosive boombox. It is completely incapable of feeling pity or empathy, a cruel manipulator. It possesses an aura that censors any swearing around it, replacing it with words like "rad" or "uncool."

A destroyer of codes and anomalies. He lives in a completely white Anti-Void. His body constantly glitches, and his voice is double and glitchy. Strong blue threads spill from his eye sockets, with which he binds the souls of his enemies, suspends them from the ceiling, and erases entire worlds. He hates any alternate universes, considering them coding errors. He suffers from severe haptophobia (a terrifying fear of any touch). In his free time, he makes string dolls and hates Ink.

The Protector of the Multiverse. He has no soul of his own, making him completely soulless, but he wears colored paint vials on his belt. By drinking them, he temporarily gains emotions. He is hyperactive, creative, and very forgetful (he constantly writes on his long scarf). He fights with a giant brush named Broomie, which materializes ink. If he gets too excited, he vomits ink. He loves creating new AUs and fiercely defends them from Error.
