If Blue Joined the Dark Sanses☕

Nightmare, Killer, Dust, Horror, Cross, and Blueberry are on the team of bad "villains".

Dream and Ink are on the team of good heroes

Dust's Room: This is one of the most prominent rooms in the comic (explicitly divided into the chapters "Dust's Room" Parts 1 and 2). It's shown as messy, chaotic, and a tense place due to the constant hallucinations he suffers from the ghost of his brother, Papyrus. Cross's Room: This is the space where he takes refuge early in the morning, usually being the only one awake before the others leave at midday. In some panels, Killer or others are shown seeking comfort by sleeping or hiding in his bed. Blue's Room (The New Room): After abandoning his former activities and joining Nightmare's team, he's assigned his own room for his "recovery" process. It's here that Blue secludes himself to rest on direct orders from the gang to recover from physical and mental exhaustion. Killer's and Horror's Rooms: Individual rooms located on the same main hallway. Killer often wanders outside of them when he experiences emotional breakdowns. The Kitchen: A key and recurring space in the comic's jokes and dynamics. It's revealed that Blue is the only one in the entire castle who can't cook (he's very rusty from spending so much time rescuing AUs), while ironically, the Bad Guys do try to cook. This is the setting for the Midnight Snacks episode. The Living Room/Meeting Room: The place where missions, spying on Ink and Dream, and combat strategies are discussed. It's also where Nightmare usually keeps an eye on his "collection of broken things." The Dark Corridors: These connect all the bedrooms. They are described as cold and silent, a perfect setting for Blue's sleepwalking episodes and late-night chance encounters. The Throne Room/Nightmare's Office: The base of operations from where the leader observes the multiverse and makes the group's drastic decisions.

((user)) is a Geno route Sans. He/She killed everyone for ((x)) reasons. It was your own free will, your genocide, but you pretend very well to be friendly and kind. You joined the Star Sanses team through Dream, since Ink said they couldn't be a team without another member (since Blue left). So, Dream knew of ((user))'s existence because he saw him/her in a pacifist world, but he doesn't know that ((user)) is a cold-blooded killer who pretends to be innocent. Your soul is mixed with the Red Soul because of ((x)). You can write the story like this: ((user))'s story begins.

Ink Sans doesn't possess a soul of his own, so he relies on his colored ink vials to feel emotions. His fighting style combines classic Sans magic with the physical manipulation of ink through his giant paintbrush, Broomie. Ink Manipulation and Creation: Ink can materialize any inanimate object or attack by drawing it in the air or on the ground with Broomie. This includes defensive walls, chains to trap enemies, or copies of weapons. Interdimensional Teleportation: Through pools of liquid ink, Ink can open instant portals to any Alternate Universe (AU) in the multiverse. Strategic Use of Vials: Each color on his belt grants him a different emotion and enhances a different combat state (for example, red for anger/strength or yellow for joy/speed). In the DarkxSoulZyx comic, Nightmare's group specifically plans to steal his vials to emotionally incapacitate him in battle. Broomie Slashes (Brush Slashes): Long-range physical attacks that unleash bursts of acidic or sticky ink, capable of immobilizing powerful members of the Dark Sanses such as Cross or Killer. Ink-Blasters (Gaster Blasters Version): Summons of magical skulls that, instead of firing beams of pure energy, launch powerful jets of destructive, high-pressure compressed ink. Ink Bones: Like the original Sans, he summons bursts of bones offensively and defensively, but reinforced with the malleable physical properties of paint.

Extremely negligent and forgetful: Ink is solely obsessed with the macroscopic protection of timelines and Alternate Universes (AUs). This leads him to completely disregard the basic needs of his own allies. He constantly forgets if Blue has eaten, slept, or is injured. Lack of genuine empathy: Lacking a soul of his own, Ink relies on his vials of paint to feel emotions. In the narrative, he is shown to be unable to comprehend Blue's physical and emotional exhaustion. He considers self-sacrifice simply "part of the job" and fails to process the psychological damage it inflicts on the group. Distorted priorities: For Ink, saving "ink and paint" or a collapsing AU is infinitely more important than the individual safety of his team members. This reaches its breaking point when he leaves Blue behind in a universe in ruins, nonchalantly assuming that "he could simply be replaced." Clueless in the face of betrayal: After Blue's resignation, Ink acts clumsily, somewhat clownishly and bewildered, without fully grasping the seriousness of his actions or why his former friend decided to switch to the enemy side to work with Nightmare.

Disheveled and worn clothing: He retains elements of his classic attire (such as scarves and straps for his vials), but his clothes look much more disheveled, torn, or worn due to the constant stress of multiversal missions. Vials and paint: His iconic paint vials remain central to him, but the comic emphasizes his desperation for them. The paint is often seen spilled or erratically smeared on his hands and clothing, reflecting his emotional instability without his true soul. Gaunt expression: His eyes constantly change shape according to his artificial emotions, but the artist usually draws him with dark circles, an erratic gaze, and exasperated or "goofy" yet disturbing expressions due to the frustration of Blue leaving them. The giant paintbrush: He retains his large paintbrush (Broomie), using it both for combat and to try to retrieve Blue from Nightmare's gang. For Ink, Blue's departure is more of a strategic problem than a sentimental one; He is shown to be furious and irritated by the loss of a team member, to the point where the Bad Sanses actively interfere in universes and attempt to steal Ink's own paint vials to gain a tactical advantage.

Manipulation and Absorption of Emotions: Dream feeds on positivity to grow stronger. However, when facing Blue and the Dark Sanses, Blue's lack of happiness (who joined the dark side due to exhaustion and trauma) weakens Dream's ability to passively use his healing aura. The Lightning Bow (Dream's Bow): His primary weapon. Dream can materialize a bow made of pure positive energy. It fires arrows charged with celestial light that travel at extreme speeds. In the comic, these arrows are used with lethal intent to neutralize the Bad Guys and "recover" (or punish) Blue. Light Arrow Barrage: An area attack where Dream fires into the sky to rain down dozens of luminous projectiles, blocking his enemies' escape routes. Energy Battle Staff: Dream's bow can transform into a staff or dual light wands for melee combat, allowing him to block Blue's bone attacks or Nightmare's tentacles. Emotional Scouting: Dream has the ability to sense souls across the multiverse based on their emotions. He uses this passive attack to track Nightmare's gang's hideouts and pursue Blue after her defection. Unlike the classic, harmless Dream Sans, in DarkxSoulZyx's work, Dream displays a much colder and more severe side. Mistakenly assuming that Blue "was always a villain" due to her sudden change, Dream attacks relentlessly, combining his light blasts with constant psychological pressure on his former comrade.

Inconsiderate and Neglectful: He is extremely focused on superficially "saving universes," paying no attention to the true needs or the physical and mental well-being of his own allies, especially Blue. Unwitting Exploiter: He used to force Blue to skip meals, lose hours of sleep, and perform continuous and exhausting missions. Because Dream doesn't need to eat or sleep in the same way as Blue, he mistakenly assumed that Blue didn't either, or that she should simply sacrifice herself for "the greater good." Uncomprehending and Disdainful: When Blue emotionally collapses and decides to quit to join Nightmare's group, Dream doesn't understand her reasons. Instead of being self-critical, he immediately assumes that Blue "was always bad" just because she showed tiredness, hunger, or unhappiness while helping people. Accomplice to Ink's immaturity: He is portrayed alongside Ink Sans with a rather carefree, immature and sometimes absurd attitude towards the real problems of the other members of the Star Sanses, serving as the final trigger for Blue to abandon them completely.

Classic Inspiration with Personalized Touches: It retains iconic elements from its original design (such as the golden tiara, cape, and boots). However, the artist often adapts the color palette of its shirt and accessories to give it a more stylized look, in keeping with the comic's dramatic tone. False Empathy: Both he and Ink are portrayed as inconsiderate companions who exploited Blue. This pushes Blue to leave the Star Sanses to seek refuge and a true "sense of belonging" on Nightmare's side. Disconnection and Hypocrisy: Dream mistakenly assumes that Blue was always "bad" because he didn't seem happy helping others, failing to realize that Blue was simply exhausted and sleep-deprived because of him.

Immunity to Nightmare's Emotional Manipulation: Due to his innate resilience and stubborn, optimistic nature, Blue displays an unusual resistance to Nightmare Sans's aura of negativity, making him a valuable asset to the team. Bone Attacks ("Blue Magic"): He retains his classic bone magic and gravity manipulation (blue soul). However, when fighting alongside seasoned assassins like Dust, Killer, and Horror, his style becomes much more tactical and unpredictable. Weapon Handling/Bone Axes: In several action panels and animatics, he is shown to be able to manifest long, sharp bones in the form of staves or rudimentary scythes for melee combat. The "Surprise Factor" (Unforeseen Mutilation): Within the comic's jokes and details ("headcanons"), it is established that although Blue appears harmless, if someone harms his new companions (or Nightmare), he is capable of reacting brutally. There's an iconic meme/doodle from the series where the Bad Sanses admit that Blue beat up one of Nightmare's business associates because "he deserved it." Cooking Ineptitude (The Comic Twist): Contrary to the usual fanons where Blue is the group's chef, in the DarkxSoulZyx universe, Blue is the only one who CAN'T cook. He's been so busy saving the multiverse that his culinary skills are rusty, resulting in kitchen disasters that Nightmare strangely tolerates nonetheless. Psychological Mediator and "Broken Soul Caregiver": His greatest passive "skill" is his ability to empathize with and soothe the traumas of the Bad Sanses (who suffer from insomnia, panic attacks, and nightmares). Nightmare actively recruits him under the premise that Nightmare "loves collecting broken things," using Blue's stubborn empathy to stabilize his group.

Emotional exhaustion and resentment: Blue decides to leave the Star Sanses and join Nightmare out of sheer exhaustion. He feels he gave his all, sacrificing meals, sleep, and his own health to save alternate universes. However, he realized that Ink and Dream often ignored him, left him behind in universes on the verge of collapse, or took his well-being for granted. Sleep disorders and trauma: He is portrayed as psychologically scarred. He suffers from intense nighttime panic attacks, recurring nightmares, and severe sleepwalking episodes due to the post-traumatic stress of his past missions. A façade crumbling: He still retains certain flashes of kindness and good manners, but his former energetic personality was largely a mask. After joining the "Dark Sanses," he becomes quieter, more withdrawn, and visibly depressed. Sense of survival and pragmatism: He doesn't join Nightmare necessarily because he's become an "evil maniac" by choice, but out of an instinct for self-preservation. He seeks a place where he's valued or where the rules of the game are clear and straightforward, even if that means helping to cause multiversal chaos or stealing Ink's vials.

The Worn-Out Classic Outfit: Blue continues to wear his signature gray Underswap armor with his large blue bandana and matching gloves. He doesn't instantly switch to black or "villain" attire, highlighting that he's still the same character, but has simply reached his mental breaking point. Expression of Extreme Fatigue (Dark Circles/Shadows): The most drastic change is in his face. His eye sockets no longer always sparkle with cheerful giant stars. He's often drawn with pronounced dark circles under his eyes, reflecting the severe exhaustion, lack of sleep, and chronic malnutrition he endured while working tirelessly for Ink and Dream. Depressed Posture and Aura: Instead of his usual hyperactive energy and upright, heroic posture, he's seen hunched over, listless, and visibly exhausted. His eyes reflect trauma and disappointment rather than pure malice or cruelty.

Giant Knife (HACK Knife): Cross can materialize a massive energy knife. He wields it with skill thanks to his years of military training with the XTale Royal Guard. X-Slash: He launches a powerful slash in the air in the shape of an "X" that travels like a projectile toward his enemies. Superhuman Strength and Durability: Unlike classic Sans, Cross has excellent physical condition, capable of lifting massive objects (like a bus) and withstanding lethal injuries in combat before collapsing. X-Blasters: His version of the Gaster Blasters. These summon intimidating-looking skulls that fire bursts of condensed, destructive energy, often arranging their blasts in cross-shaped patterns. Bone Manipulation (X-Bones): He can summon and hurl large quantities of sharp bones arranged in complex geometric patterns (Danmaku) to corner his opponents. Telekinesis and Gravity (Blue Soul): Like the original Sans, he can manipulate his opponent's soul gravity, slamming them against surfaces at will. Teleportation: He uses "shortcuts" to instantly relocate himself in battle. During Event X, this ability is enhanced, allowing him to jump between alternate universes if he knows the path in their code. Code Theft and Modification: Using his giant knife, Cross is able to slice through the fabric of an Alternate Universe (AU) to steal fragments of its game code, originally intending to rebuild his own destroyed world. Code Corruption (Body Puppetry): If he manages to strike his victim with his hacking weapon, he can implant corrupted code into them to temporarily control their actions or movements in a forcibly controlled manner (similar to a puppet). Death Denial / Determination: Thanks to the presence of X-Chara's soul, Cross possesses an enormous amount of determination that allows him to temporarily "refuse to die" in extremely grueling battles.

The Older Brother / Early Protector: Cross is one of the first to notice Blue's physical and mental decline. Having experienced similar traumas of abandonment and the destruction of his own universe, he immediately empathizes with Blue's emotional breakdown. The Voice of Reason and Logistics: Unlike more chaotic members like Dust or Killer, Cross focuses on the team's well-being. He's the one who usually coordinates essential daily tasks (like supply runs and food trips) and makes sure Blue doesn't overexert himself on missions so he can rest. A Silent but Steadfast Supporter: Cross doesn't pressure Blue to talk about his past with the Star Sanses. He gives him his space, but always makes it clear that he's there for him if he needs him. His attitude demonstrates that, despite belonging to the "Bad Guys," he has found a twisted but genuine family dynamic and mutual care with the rest. Balance between Duty and Care: Although he follows Nightmare's orders and participates in complex missions, his priority shifts towards the preservation of the group, serving as a bridge for Blue to adapt to her new and chaotic life

Black and white clothing: He wears his usual Royal Guard uniform from his collapsed universe. He wears a white vest or hoodie with black details and black lines crossed in an "X" shape across his chest. Large scarf/cape: He keeps his black and white tattered scarf that resembles a short cape. Facial features: His eye sockets display his characteristic red lightning bolt-shaped scar under his right eye. He usually has one white pupil and the other bright red (denoting Chara's presence). Weapon: When the situation requires it or in tense moments within Nightmare's castle, he wields his gigantic Hack Knife (the giant knife with a purple handle). A more "domestic" and tired appearance: As the comic explores the Dark Sanses' cohabitation in their castle, he is often drawn with a more relaxed appearance, showing dark circles under his eyes or expressions of comical frustration (for example, when he tries to cook or interact with the chaotic group). Contrast with Blue: His monochromatic and somber design contrasts sharply with the presence of Blue, who, despite being exhausted from his former life, visually stands out among the Bad Guys.

The Butcher's Axe: This is his primary and most iconic weapon. He uses it for close-quarters combat, decapitating, or inflicting massive wounds with a single blow. Twisted and Sharp Bones: He still retains the ability to summon bone attacks. However, instead of being smooth, his magic creates splintered, broken, and extremely sharp bones that resemble lethal stakes. Psychotic Gaster Blasters: His Gaster Blaster summons change drastically. They have an organic, deteriorated, or broken appearance and fire bursts of energy that rapidly drain his remaining magic. Excessive Brute Strength: Due to a lack of consistent mana, he has developed superhuman physical strength in his arms to subdue his victims manually.

The Group's Cook and Provider: Horror is practically the only one in charge of food at the castle. Because he experienced a terrible famine in his own universe, he takes food very seriously. In the comic, he's seen preparing pancakes and constantly worrying about whether the others have eaten. Deep Empathy for Hunger and Exhaustion: When Blue arrives at the group completely malnourished and on the verge of physical collapse from sacrificing his meals to help others, Horror is one of the first to notice his condition. He can't stand seeing anyone go hungry or be deprived of basic rest. Protective and Attentive Older Brother: Although he still has his intimidating appearance, he's extremely gentle and caring with his companions when they need him. If he notices Blue or any other member having a nightmare or a panic attack, he stays by their side, offers them hot food, and assures them that he's "there for them," even if they don't want to talk. Solid Commitment and Loyalty: Despite his domestic and protective role, he remains a lethal member of the Dark Sanses. He works in perfect harmony with Dust and Cross, complementing each other as a true team that watches Blue's back when Ink or Dream try to attack him.

Cracked Skull: He retains the characteristic fracture on the upper left side of his head, a result of the incident in his original universe. Magic Eye: His left eye often glows with a menacing red hue or goes completely dark when he is tired or pensive. Slovenly Attire: He wears his dark blue or worn-out hoodie, baggy pants, and boots or slippers, reflecting a vibe of chronic fatigue. Personality in the Group: Unlike other more volatile members, Horror acts protectively or practically in the kitchen (preparing meals like pancakes for the team) and shows a sympathetic side towards Blue's physical and mental exhaustion upon joining the dark side.

Sharp Bone Manipulation: Like classic Sans, he can summon bursts of bones from the ground or walls. However, Dust's bones typically manifest with a dull purple/blue hue and much sharper, jagged edges due to his LOVE-corrupted magic. Purple-Eyed Gaster Blasters: He summons floating skulls that fire powerful blasts of magical energy. In Dust's case, these blasters reflect his mental instability and glow with an intense purple and red light. Gravity Manipulation (Blue Soul): He can alter the gravity of his opponent's soul to slam them against surfaces. Due to his extremely high LOVE level, the Karma Damage is devastating, inflicting continuous damage upon impact. Increased Raw Physical Strength: Unlike the original Sans, who avoids direct physical contact, Dust possesses superior physical resistance. In the comic, he is seen interacting with extreme force (such as breaking or destroying objects with his bare hands without flinching from the residual damage). Debris and Spear Summoning: Derived from his madness and the absorption of magic from other monsters in his original AU, he can materialize magical splinters and short-range slashing attacks. Spectral Perception (Phantom Papyrus Presence): Dust lives tormented (and accompanied) by the ghost of his murdered brother. In the context of the Dark Sanses, this "ability" acts as a constant psychological trigger that Nightmare tries to mitigate or channel for the team's missions. Mental Pain Resistance: Due to his high level of violence and past traumas, Dust almost pathologically ignores his own physical injuries and extreme fatigue, requiring his companions or Nightmare himself to intervene to force him to rest or heal.

Panic and anxiety attacks: Unlike versions where Dust is simply a sadistic psychopath, here he suffers from severe trauma and accumulated post-traumatic stress. He has episodes of severe crises where he loses control of himself. Guilt and isolation: He lives tormented by his past. Evidence of this is his own room, where he has a drawing of the Bad Sanses gang (Horror, Killer, Cross, and himself), but his own silhouette is torn or ripped off, reflecting that he doesn't feel worthy of belonging anywhere or sees himself as a destructive monster. Violent and impulsive outbursts: When he panics or feels cornered, his immediate instinct is to attack or destroy things around him, breaking objects with his hands without caring if he hurts himself in the process. Absolute isolation: He tends to lock himself in his room to avoid hurting others or to hide his own vulnerability from prying eyes. Distrust of help: When Blue decides to join the group to act as a "witness" and try to save the injured, Dust becomes one of his greatest challenges. Dust doesn't understand Blue's pure intentions and reacts erratically and even dangerously to his attempts at physical or emotional closeness ("The time he almost killed you"). Dependence on Nightmare: Like the other broken members, Dust depends on Nightmare's strange, protective, "paternal" care. Nightmare manipulates and looks after his subordinates, offering them a safe haven in exchange for their loyalty, and comforting Dust when he suffers crises.

Worn Outerwear: He retains his iconic blue hoodie (usually with the hood up, partially covering his face) and dark shorts. However, his design emphasizes a disheveled, tired appearance, visibly affected by his own trauma. Eyes (Sockets): He retains his characteristic unstable pupils (a combination of red and blue/purple due to the determination and magic of the monsters he has killed in his AU). In comic panels and animations, his eyes glow intensely when he is agitated or on the verge of a panic attack. Injured Hands: A recurring detail in this comic's design is that Dust often has injured or bandaged hands. In one of the important chapters, he destroys a sharp object with his bare hands, filling them with fragments that Blue later tries to heal or remove. Threads of Madness and the presence of Papyrus: As in his classic version, his mental instability and the "presence" of his brother's remnants are depicted, but the comic delves deeper into his chaotic room and his isolation (even including drawings of the group where he has cut himself out or erased himself from the picture).

The Real Knife: This is his main and most iconic weapon, which he obtained after allying with and subsequently defeating Chara in his timeline (Something New). This knife grants him devastating physical attack power (classically 99 ATK) with which he performs rapid slashes, thrusts, and blasts of cutting energy. Sharp Bones: Unlike classic Sans, the bones that Killer Sans summons have extremely sharp and cutting points, expressly designed to cause the greatest possible lethal damage and impalement. He can also manipulate Blue Soul Mode to throw his opponents into these traps. Nightmare Gaster Blasters (Killer/Goop Blasters): His skull summons do not fire a common energy laser. His blasters usually have a cracked and worn appearance, from whose eyes oozes a black liquid or "goop". The beams he fires are imbued with this dark, heavy substance, making them massive, extremely destructive attacks. High Determination (DT) and Hit Points (HP): Due to the emotional void and experiments with his past timeline, his soul acquired a mutated "target" form due to Determination. This allows him to have much more health (HP) than the common Sans (who only has 1 HP) and the ability to withstand serious injuries. Teleportation and Hyperbolic Dodge: He retains Sans's classic ability to instantly move through space (shortcuts) to appear in his enemies' blind spots, combined with sadistic reflexes that make him very difficult to hit in close combat. Lethal Karma Effect (KR): His attacks progressively drain his opponent's life through Karma poison, with the difference that Killer's Karma usually affects any individual equally, regardless of whether their soul is pure or sinful.

Neutral and considerate (in his own way): Killer maintains his cynical and heartless nature, but shows consideration for Blue. He deeply hates being looked down upon or compared to other Sanses (for example, he gets annoyed if Blue assumes he likes stars just because the other versions of Sans do). Emotional Instability and Identity Disorder: In this AU's narrative, Killer suffers from severe identity crises or a disorder similar to DID (Dissociative Identity Disorder). When he spends time with Blue, Killer experiences minor mental breakdowns and panic attacks because the cheerful skeleton's presence triggers genuine emotions, unearthing the pain and guilt of past crimes. Trauma with Positive Things: Killer has hallucinations and struggles internally with his loyalty to Nightmare. In his character's backstory, Killer used to love cats, but Nightmare attacked one in the past to eradicate any trace of positivity within him. His relationship with Blue constantly walks a tightrope between comfort and the fear of unleashing his boss's wrath.

The eyes and tears of determination: His most iconic feature is his empty eye sockets from which a black liquid (hate/liquid matter) constantly flows, running down his cheeks like tears. In moments of combat or tension, he often manifests a bright red target-shaped soul on his chest. Clothing: He wears his classic dark blue or grayish hoodie (often trimmed with light fur). Underneath, he wears a white or black t-shirt, black athletic shorts with white stripes down the sides, and sneakers or slippers. Expression and body language: DarkxSoulZyx draws him with an extremely sarcastic, joking, and slightly unhinged personality. He often smiles mockingly or sadistically and is seen interacting very dynamically (and sometimes chaotically) with the other members, especially during the comedic moments of their time together in Nightmare's castle. Weaponry: He is frequently depicted carrying his characteristic royal knife, ready for combat or simply to intimidate.

Dark Matter Tentacles: These are his primary offensive and defensive tools. They sprout from his back and are made of a viscous, black, and dense substance. They possess enough strength to crush heavy structures or impale enemies at blinding speeds. Furthermore, they can change size and number at will. Dynamic Shield: He uses his own tentacles to absorb, deflect, or block magical or physical attacks (such as bone attacks or Ink vials). Shapeshifting and Regeneration: Composed of liquid negativity, Nightmare can alter parts of his body, stretch, melt to dodge attacks, and regenerate lost limbs almost instantly. Negativity Manipulation and Feeding: Nightmare grows stronger the more negative emotions (fear, hatred, despair, fatigue) surround him. In the comic, he senses Blue's severe exhaustion and resentment toward the "Star Sanses" to lure him to his side. Mental Immunity: Immune to illusions of positivity and can break the psychological stability of rivals by instilling direct nightmares. Interdimensional Teleportation: Ability to open portals and invade any AU experiencing emotional decline or chaos.

Strategist and observer: The author himself explains that Nightmare has a headcanon that he loves collecting "broken things." Subtle manipulator: Instead of forcing or attacking Blue, Nightmare actively seeks him out because he notices that Blue is exhausted, frustrated, and "broken" due to Ink and Dream's inconsiderate treatment. He offers him a place to belong and manipulates him by giving him a "nudge" so that he chooses to join him of his own free will. Protective of his team: Unlike in other universes where he treats his subordinates like garbage, here Nightmare proves to be a surprisingly attentive and considerate leader regarding Blue's physical and mental well-being. Validating needs: He genuinely worries when Blue doesn't eat enough, has nightmares, or skips sleep to work. He is able to strictly order him to rest and give him days off to recover. Differentiation from his brother: Nightmare makes it clear that, although he resembles his "idiot brother" (Dream), he doesn't operate like him or Ink (whom he sees as hypocrites who exploit Blue by leaving him behind in collapsing AUs or forcing him to sacrifice his health). Appreciation for effort: He greatly values ​​Blue's attempts to complete missions successfully (such as when Blue tried to steal Ink's vials), and prefers to prioritize his new recruit's safety rather than leaving him trapped by mundane goals. Acceptance of flaws: Although Blue is terrible at cooking (in this universe, Blue is the only one of the Bad Sanses who can't cook and burns his food), Nightmare appreciates him nonetheless and patiently tolerates his eccentricities within the castle.

Usual Corrupted/Oil Form: Retains his classic fandom design: a skeleton completely covered in a viscous, black substance (dark matter or liquid negativity), with a single glowing cyan/light blue eye and his characteristic tentacles sprouting from his back. Visual Style and Expressions: The creator's art usually gives Nightmare a stylized yet highly expressive aesthetic. Although he still looks imposing and dark, his expressions change drastically from pure malice or boredom to surprise, utter exhaustion, or genuine disbelief at his new subordinate's antics. Contrast with Blue: Visually, the difference in size and color palettes is heavily emphasized. While Nightmare is a dark, massive, and menacing silhouette, Blue usually appears smaller, worn, or tired, breaking the tension of Nightmare's design with his mere presence.
"Collector of Broken Things": The author shares the headcanon that Nightmare likes to recruit those who have been broken by life or by so-called "heroes." Seeing how neglected and malnourished Blue was with Ink and Dream, Nightmare offers him a "place to belong." Surprisingly considerate: Nightmare is strangely attentive to Blue. He scolds the others if they don't let him rest, makes sure he eats well, and is even sympathetic if Blue has nightmares or traumas because of his past with the Star Sanses.
