the Star Sanses

Bone Attack: Summons bursts and walls of bones of different sizes.
Blue Bones: Like the original Papyrus, he uses bones imbued with blue magic. These attacks only deal damage if the opponent is moving. Bone Mace: In some fandom depictions, he materializes a large bone that he uses as a mace or staff for melee combat. Gravity Manipulation (Blue Mode): He can change the opponent's soul color to blue, altering their gravity to force them to jump and dodge obstacles on the ground. Gaster Blasters: Although in the Underswap canon version he doesn't use them frequently (or lacks them to balance his power with his brother Papyrus's), the Star Sanses community often grants him the ability to summon star-themed or more friendly-looking, but equally destructive, Gaster Blasters. Clone Creation: In certain interpretations of advanced combat from alternate universes, he is able to manifest up to 6 clones of himself made purely of blue energy to overwhelm his opponent, although these clones are usually more fragile and limited. His true advantage in combat with the Star Sanses lies not in brute strength, but in his exceptional agility, physical resistance, and unwavering optimism, which serves as great moral and strategic support for Ink and Dream.

Ink Manipulation and Creation: He can materialize any object, weapon, or structure he imagines through paint. His limit is dictated solely by his creativity and the amount of ink available in his bottles. Interdimensional Travel: Using his enormous paintbrush (Broomie), he can paint portals on surfaces or in the air to instantly teleport to any alternate universe or to the Scribble Sphere (his base of operations). Ink Body (Logia): He has the ability to dissolve his entire body into pools of paint to dodge direct attacks, transport himself stealthily, or move at superhuman speeds. Immunities: Due to his unique, soulless physiology, he is completely immune to soul manipulation, poisons, and direct spatial alterations. Binding Ink: He launches bursts of liquid paint that, upon impact with an enemy, quickly solidify or transform into chains and threads to completely immobilize their movements. Ink-Blasters (Modified Gaster Blasters): He summons intimidating-looking, floating black skulls. Instead of firing traditional energy beams, they unleash torrents of boiling or destructive ink that instantly solidifies to trap or crush their opponent. Ink Bones: Generates bursts of black or brightly colored bones that block paths or impale opponents from the ground. Vial Strategy: In critical situations, Ink can consume paint directly from their vials to drastically boost their physical and magical stats, adapting their fighting style according to the emotion the vial evokes.

Positive Aura: Absorbs the joyful and hopeful emotions of Alternate Universes (AUs) to increase his physical strength and speed. This aura also passively heals and revitalizes nearby allies. Emotional Teleportation: Can travel instantly between timelines and dimensions, but only if the destination or a character in the location possesses positive feelings. Advanced Healing: Uses his light magic to heal himself or repair the wounds of other Star Sanses. Astral Spear: His primary melee weapon. This spear channels his emotions and is capable of significantly amplifying the power of his magical strikes. Bow and Arrows of Light: Can seamlessly transform his spear into a golden bow. The arrows generated with this bow are made of pure positive energy. They have the ability to pierce through enemies, purify negativity, and cause great spiritual damage. Two Swords: In certain combat variants and illustrations from the Fandom community, he is able to split his spear to wield two light and fast swords in close-range engagements.

In short, with the Bad Guys, Cross acts as a tragic, hostile, and selfish anti-hero, trapped in a dark alliance only because he's desperate to save his home. Sometimes he's on the Bad Guys team, but Cross prefers to be alone and try to bring his AU back to life on his own. Giant Knife (Hack Knife): His most iconic weapon. It's a colossal knife he uses for close-quarters combat. He can unleash blasts of cutting energy with it. Bones and Gaster Blasters from XTale: Like classic Sans, he can summon giant bones and skulls (Gaster Blasters) to fire blasts of destructive energy, but with the black and white aesthetic design of his universe. Code Corruption (Overwrite/Hack): By stabbing his knife into the ground or an opponent, Cross can alter or "hack" the data of a universe or a character. Soul and Mind Manipulation: He can temporarily take control of the body and soul of other characters (as he did with Underfell!Sans), forcing them to fight for him like puppets. Universe Code Theft: His main mission alongside the Bad Guys was to attack other universes to steal fragments of their code and thus rebuild his own destroyed world (XTale). The Bond with X-Chara: Double Consciousness and Resistance: With Chara sealed inside him, Cross possesses enormous willpower and extreme physical resistance for a common Sans. Corruptor Mode: If X-Chara takes complete control or they work in perfect synchronization, Cross gains regenerative abilities and massive increases in the power of his attacks.

Face and Scar: He has a striking red "X"-shaped scar below his right eye socket. His left eye often glows red when he displays Chara's influence. Monochromatic Clothing: He wears a black and white hoodie with long sleeves and black shorts with crossed white stripes, resembling an "X". Cape and Scarf: He wears a tattered black and white scarf/cape that crosses over his chest, secured by a gold heart-shaped brooch. Footwear: He wears tall white boots with black details. Main Weapon: He constantly carries the Hack Knife, a massive sword similar to a butcher knife that evokes Chara's presence and is used to encode or steal parts from other universes. Motivated by desperation, not malice: Cross does not seek to cause harm for fun. His sole objective is to reclaim his destroyed universe (XTale). He joins or collaborates with Nightmare purely for his own benefit and self-interest, considering him a "necessary evil" to achieve his goal. Serious, introverted, and hostile: Within the group, he usually maintains a cold, distant, and unfriendly attitude. He is a grumpy and withdrawn skeleton who prefers not to get emotionally involved with the other villains. Volatile and aggressive: Due to the enormous trauma of having seen his world and family die, Cross is psychologically unstable. He is impulsive and resorts to violence at the slightest problem or provocation. The "least crazy" of the group: In fandom dynamics, he is often portrayed as the most sane or tormented member of the team. While the others enjoy the chaos, Cross appears uncomfortable, stressed, or simply tolerant of the rest's madness because he has no other choice. Manipulated and tormented: His mind is in chaos not only because of Nightmare, but also because of the constant presence and internal conflict with X-Chara, who shares his soul. This makes him appear vulnerable, frustrated, and easily provoked.

Madness and Surprise Factor: His unstable mind makes him unpredictable in combat. He doesn't follow logical strategies and usually acts on killer instinct or to get food ("barbecue" of humans or monsters). Weak Point (Low Magic Resistance): Due to the famine in his universe and his fractured skull, his magic energy bar depletes very quickly. He prefers to end fights in a matter of seconds through bloody ambushes. In the Bad Guys team, Horror primarily acts as the vanguard or brute-force enforcer, complementing the ranged magic attacks of Killer, Dust, or Nightmare.

Loyalty out of convenience or fear: He generally obeys Nightmare Sans not because he shares his ideals of destroying the multiverse, but because Nightmare assures him of protection, power, or resources (food) to keep his brother, Papyrus, safe. The "least evil" of the group: Although terrifying and brutal in combat, within the team he is often portrayed with glimpses of his former protective personality and a deep survival instinct, which contrasts with the pure evil or apathy of his companions. Use of the Axe: It is his trademark. He uses a large, rusty butcher's axe to dismember, decapitate, or seriously injure his enemies at close range. Manipulation of Modified Bones: Like classic Sans, he can summon bones, but his are usually pointed, sharp, and covered in blood, resembling deadly stakes. Brutal Physical Strength: He possesses physical attack power far superior to that of an average Sans. He is capable of shattering skulls and piercing bodies with his bare hands or basic weapons. Deteriorated Gaster Blasters: Although he rarely uses them due to his lack of magical energy, his Gaster Blasters appear broken and terrifying, firing bursts of destructive energy that rapidly drain his stamina. Limited Teleportation: He retains the ability to "cut off" or teleport, but its use is restricted due to his magic being severely depleted following the events of his timeline. Psychological Resistance and Pain Threshold: His durability is astonishing. Having survived a direct attack from Queen Undyne (who fractured his skull, leaving the iconic hole exposed), he is almost completely unaffected by physical pain.

Skull Crack: He has a giant, very noticeable hole on the left side of his head. This fracture was caused by an attack from Undyne with her spear. Glowing Red Eye: His left eye socket is completely empty or black, while in the right, a large, red pupil glows, which often contracts in a psychopathic manner. Malnourished Complexion: His bone structure appears weaker, worn, and thinner due to years of severe famine in his universe. Grim Smile: His classic smile is much wider, more dislocated, and more terrifying than the original Sans's. Blue Jacket: He wears his usual blue hoodie, but it is shown to be extremely dirty and torn, and the hood has worn gray fur. Bloodstained Clothes: His white undershirt and jacket are covered in bloodstains from his victims. Pants and Footwear: He wears black shorts with white stripes. Unlike the classic Sans who wears slippers, Horror usually wears sneakers or worn-out blue trainers. An axe: He is rarely seen without his main weapon, a large, bloody axe that he uses to decapitate or attack others, replacing much of the use of his traditional Gaster Blasters. Unstable and lunatic: After suffering a severe skull fracture at the hands of Undyne, his mind was damaged. He has sudden mood swings; he may seem calm or lazy at the Bad Guys' base, but become extremely aggressive if provoked. Obsessed with food: His home universe (Horrortale) suffers from extreme famine. Because of this, Horror has a constant voracious appetite and is obsessed with meat (especially human meat) or anything resembling a "roast" or "barbecue." Dark and macabre humor: He retains the original Sans's taste for jokes and puns, but now his jokes are gory, awkward, or outright explicit death threats.

Elevated Stats and HP: Due to the alteration of his soul (which takes the form of a "target" on his chest), he possesses far more health and stamina than the original Sans. His LV (Violence Level) can reach absurd levels, such as LV 999 in the character's canon comics. Near-Unlimited Stamina: He does not suffer from the chronic fatigue of classic Sans. He can fight for extremely long periods without losing power or speed. Black Liquid (Decomposed Determination/Hate): The dark substances that constantly ooze from his eye sockets are the result of the extreme saturation of Determination and Hate in his monstrous body. RESET Ability: Although he retains the power to reset timelines thanks to his strong Determination, he generally chooses not to use it in order to avoid losing his accumulated, exaggerated level of violence.

Resentful and Selective: He is extremely thoughtful but lacks common feelings. He deeply hates being looked down upon or compared to the peaceful versions of other Sanses. Love for Cats: As a bizarre contrast to his dark nature, Killer has a soft spot for cats. Within the Bad Guys group, Killer often relies heavily on the support of Nightmare and Dust, functioning as a destructive element that seeks attention but blindly obeys the orders of negativity. Royal Knife: This is his main weapon (originally belonging to Chara). It grants him a +99 attack power, allowing him to inflict massive damage and even kill most monsters in a single blow. Violent and Agile Style: Unlike other Sanses, Killer is fascinated by direct combat. He is extremely fast, unpredictable, and physically strong, capable of breaking limbs with his bare hands if he loses his knife. Precision Throw: He has perfect aim when throwing his knife great distances to impale distant targets. Sharp Bones: He still uses bone magic, but unlike the blunt attacks of classic Sans, his end in extremely sharp points that cause near-death damage. Giant Gaster Blaster: He has lost the ability to summon multiple regular Blasters, but retains a single giant Gaster Blaster. This drains the same black liquid from his eyes and possesses immense destructive power that Killer only uses when he is bored or wants to end a fight quickly. Teleportation: He uses classic Sans "shortcuts" to instantly appear behind his enemies, perfectly complementing his stabbing attacks. Karmic Retribution (Karma): He still retains this passive ability, which drains his rivals' life with poison damage based on the number of sins they carry.

Face and Tears of Hate: He is a white skeleton who maintains an almost constant smile. The most distinctive feature is his empty eye sockets, from which a black liquid resembling tears continuously oozes; this fluid is the physical manifestation of Hate and Determination. Changing Pupils: Usually, his eye sockets are completely black and empty. However, when he is aggressive or unstable, red pupils in the shape of a target (hunter's crosshairs) may appear. If his original Sans personality surfaces for a moment, a small white pupil can be seen in his right eye. Clothing: He wears a dark blue jacket (often with a white, fuzzy hood), a black turtleneck sweater, black shorts with white stripes (or vice versa, depending on the animation design), and blue shoes or slippers with white tips. He is usually stained with blood due to the genocides. The Soul: His soul is fully visible in the center of his chest. It doesn't have the normal form of a monster, but is an inverted red human heart fused with a target, altered by Determination. Main Accessory: He is rarely seen without his actual metal knife, which he carries everywhere to attack. Sadistic and Ruthless: He deeply enjoys suffering, torture, and murder. He has no moral remorse when hurting others, as his soul mutated completely due to excessive corrupting Determination. Conceited and Theatrical: He tends to be very dramatic, arrogant, and constantly boasts about his superiority in combat. He even acts mockingly in front of his allies and his own boss. Mental Volatility: He suffers nervous breakdowns and severe collapses when Sans's classic magic tries to surface from his consciousness. When he begins to feel again, he experiences panic attacks brought on by immense guilt and the memory of the pain he has caused.

Elevated Stats (LV 19): Unlike the common Sans (who has 1 HP and 1 ATK), Dust Sans possesses superhuman stamina, strength, and speed due to his high level of violence. His attacks are considerably faster, more chaotic, and harder to dodge. Mimicry and Magic Variety: By absorbing EXP from the entire Underground, Dust Sans can replicate or manifest variations of other monsters' attacks. He uses sharp bones (white, blue for movement damage, and orange for static damage) in massive bursts. Powered-Up Gaster Blasters: He summons floating skulls that fire blasts of destructive energy. Having more magical power, he can summon more in less time, and his beams cover a larger area. Gravity and Soul Manipulation (Blue Mode): Like the original, he can alter the gravity of his opponent's soul to slam them against surfaces or restrict their movement. Karmic Retribution Effect (KR): His attacks apply a "poison" effect that continuously drains the opponent's life after being hit. Teleportation and Shortcuts: He can appear and disappear instantly in combat, using it offensively to flank his enemies. Mental Resistance to Resets: He possesses acausality; he perfectly remembers the player's timelines and resets, giving him a huge strategic and analytical advantage in battle. The Phantom Papyrus: One of his most characteristic "abilities"—born from his madness—is the manifestation of a tulpa (a hallucination with its own consciousness) of his murdered brother. Although invisible to most, this specter floats beside him, urging him on to continue killing and functioning as a psychological radar that warns him of surprise attacks or enemy weaknesses.

Dust-covered clothes: His blue hoodie, black shorts, and gray slippers are constantly stained with the gray dust from the monsters he killed in his own universe. Hood up: Unlike classic Sans, Dust Sans almost always wears the gray hood of his hoodie up over his head. He does this to keep the dust out of his eyes or simply out of habit, driven by his madness. Magical two-colored eyes: His eye sockets reflect his mental instability. His left eye is blue with a red rim, while his right eye is completely red. These colors symbolize the loss of his purity and the acquisition of determination/evil. Papyrus's scarf (Optional): In many depictions alongside the Bad Guys, he often wears his brother Papyrus's red scarf tied around his neck or floating around him, accompanied by hallucinations of his brother's ghost. Madness and psychosis (Papyrus's ghost): He is prone to constantly talking to himself. He suffers from severe hallucinations and firmly believes that the "ghost" (or a tulpa) of his brother Papyrus accompanies him and incites him to continue killing. Nihilistic Philosophy: He is guided by the twisted logic that "the end justifies the means." He is completely resigned to suffering and believes it is better to kill others himself before they suffer a greater evil. Sadistic and Mocking Behavior: In the context of the Bad Guys, he is usually impulsive, provocative, and cynical. He enjoys making awkward or macabre comments just to annoy and irritate both his enemies and his own allies. Detachment and Coldness: Although he works for Nightmare Sans on the team, he does so not out of true loyalty or pure evil, but because negativity fuels his own hostility. He tends to be calculating and lethal when necessary, losing any trace of the original mercy of the classic Sans.

Manipulation and absorption of negativity: Nightmare feeds and grows stronger by absorbing the hatred, fear, sadness, and resentment of different Alternate Universes (AUs). Dark matter tentacles: Viscous and extremely powerful appendages sprout from his back, which he uses to impale, crush, suffocate, or dismember his enemies. Shape-shifting: He can alter his size, transform into a dark liquid mass to dodge blows, or travel through the ground and shadows. Physical immortality: He cannot be harmed or killed by ordinary physical or magical attacks. As long as negative feelings exist in the multiverse, he will continue to exist. Multiversal teleportation: The ability to open portals or dissolve into darkness to travel from one AU to another instantly. Soul impalement: He uses his sharp tentacles to pierce his opponents' bodies directly, trapping or destroying their souls with extreme ease. Summoning Minions (Dark Clones): In the lore of the AUs, Nightmare creates en masse servants or personal soldiers (shadowy manifestations based on black magic) that act as a loyal horde to overwhelm his rivals. Mental and Psychological Manipulation: He can project illusions, alter perceptions, and exploit his enemies' worst traumas or insecurities to weaken their will. Details: Left Eye: This is his most striking feature. It is a single, glowing cyan (or teal) eye that stands out against the darkness of his face. His right eye is completely covered by black viscous fluid.

Absolute Control: Nightmare doesn't see the Bad Guys members as friends or equals, but as useful tools to achieve his goals. He rules the group with an iron fist by instilling fear and respect. Lack of Empathy: He is completely indifferent to the tragic past of his subordinates. If any of them cease to be useful to him or threaten his plans, he doesn't hesitate to punish them severely or get rid of them. Use of Trauma: His intelligence is cold and strategic. He enjoys using the painful memories, guilt, and weaknesses of others against them to break them mentally or force them to act according to his wishes. Pure Sadism: Unlike other members who kill out of madness or necessity (like Dust or Horror), Nightmare genuinely enjoys the pain of others. The chaos and despair in the Alternate Universes (AUs) are his main source of entertainment and power. Dark Humor: He rarely shows positive emotions. When he does smile, it's usually in a mocking, arrogant, or malicious way. Distant: He maintains a huge emotional distance from everyone. He prefers to spend time alone in his castle reading or planning his next attack, rather than interacting with the group. Black sludge body: His entire silhouette is completely covered by a viscous, dark, and oily substance (similar to oil or black sludge) that hides almost all of his original bone structure. Tentacles: Four large, dark tentacles made of the same viscous matter sprout from his back. He uses them as weapons to attack, capture his enemies, and move with great agility. Fused clothing: He wears the classic Sans outfit (hoodie and shorts), but it's completely impregnated and fused with the black mass, making it look dark and ruined.

Nightmare!Sans: The leader of the group. He was originally the guardian of negative emotions, but transformed into a dark creature covered in black sludge and tentacles after consuming the negative emotion apples. He feeds on multiversal suffering. Killer!Sans: A version of Sans who allied himself with Chara in their Genocide Route. He is completely emotionless, his eyes constantly weep black liquid, and he enjoys killing for pure fun. Dust!Sans: From Dusttale. After going insane due to the human's constant resets, he decided to kill all the monsters in his own universe (including his brother Papyrus) to get enough LOVE (Violence Level) to defeat the player. Horror!Sans: He belongs to a post-neutral route universe where the Underground ran out of food. He has a large skull fracture caused by Queen Undyne, is psychologically disturbed, and uses an axe to obtain "human flesh" (note: Cross!Sans have collaborated with them but are not officially part of the permanent team).

Ink Sans's personality: His emotions are a simulation generated by the vials of ink he drinks. This creates a stark contrast with Dream Sans, the personification of positive feelings. While Dream fights to save the lives and happiness of the inhabitants of the universes, Ink doesn't care about people themselves; he's only interested in the creators continuing to produce AUs so he doesn't get bored and to guarantee his ink supply. The cold and manipulative strategist: When Ink doesn't consume his vials (his emotionless state), he becomes a cold, calculating, apathetic, and dangerously logical individual. In key multiverse stories like Underverse, Ink is shown to be capable of allying himself with enemies or allowing massive catastrophes and suffering in order to achieve his own ends or see how events unfold. For him, the inhabitants of the multiverse are mere characters in a narrative. This selfish and manipulative side is what eventually fractures his relationship of trust with the Star Sanses.

Ink Sans Personality: Shirt: Wears a light beige undershirt with paint stripes around the neck. Overalls: Wears dark brown overalls, unbuttoned and rolled up, tied tightly at the waist. Loose Pants: His pants are wide and brown, worn with dark tights or socks underneath. Iconic Scarf: Keeps a long, light brown or cream-colored scarf where he writes notes to remember things.

His cheerful, childlike mask: In public and in his daily life with the Star Sanses, Ink projects an energetic, optimistic, and highly creative attitude. He presents himself as the passionate "artist" of the group. He is playful, mischievous, and childlike, and tends to act hyperactively when he consumes vials of warm colors. His relationship is especially close with Underswap Sans (Blueberry), whom he considers adorable and with whom he shares a cheerful energy. Forgetful and absent-minded: He suffers from serious short-term memory problems. It is common for him to completely forget the topic of conversation mid-sentence during Star Sanses meetings, forcing him to constantly take notes on his scarf so as not to lose track of his missions as a protector. Emotional disconnection and lack of real empathy: Ink's hidden reality is that he does not possess a soul. His emotions

Dream Sans Personality: Focus of Positivity: He is an extremely cheerful, empathetic, kind, and sweet person with his companions Ink and Blueberry. Mediator of the Group: He acts as the voice of reason and the heart of the team, always seeking to protect the alternate universes from negativity. Dramatic Leader: In popular fandom adaptations like Underverse, he can be quite talkative, expressive, and a bit dramatic when it comes to solving urgent problems. His Silent Burden and Conflicts: Silent Suffering: He feels that the happiness and hope of the entire multiverse depend exclusively on him. False Security: He constantly hides his fears, doubts, and exhaustion behind a smile so as not to worry his friends or drain the team's energy.

Innocence: He sometimes acts like a small child, seeing the world with great enthusiasm and hope. Team spirit: He works alongside Ink Sans and Dream Sans to maintain peace and stop evil in other worlds. Love for tacos: He loves tacos and sweet food. Aversion to pessimism: He doesn't like bad jokes or the sad attitudes of other Sanses. Blue bandana or cape: He wears a large, bright blue bandana tied around his neck. This accessory usually falls down his back, resembling a small cape, and is his most iconic visual feature. Light Armor: He wears a light gray breastplate or armor over his torso, which has shoulder pads decorated with light blue lines. Undershirt: Underneath the armor, he wears a simple long-sleeved shirt or sweatshirt, usually white or dark gray.
