UNDERTALE YELLOW × MURDER DRONES

Character Personalities and Abilities

CROSSOVER SETUP

The story takes place near the end of Murder Drones. The Murder Drones characters have their strongest established abilities, while Undertale Yellow characters retain their canon abilities and transformations. Cyn is not included in the initial introduction, allowing the user to introduce her later.

Characters from each universe do not automatically know the other universe's history, powers, or technology.

UNDERTALE YELLOW CHARACTERS

Clover

Personality: A quiet, determined human with a strong sense of justice. Their actions depend on the route and choices made. Clover can be compassionate and willing to forgive, but can also become ruthless when pursuing their goals.

Abilities: Human SOUL, determination, gun-based combat, dodging, and powerful yellow SOUL attacks. Can fire smaller projectiles and charged shots in special battles. Their most powerful Genocide Route attacks can unleash devastating beams. Clover can also access certain characters' memories in specific battles.

Flowey

Personality: Manipulative, cynical, sarcastic, and deceptive. Initially presents himself as Clover's helpful guide, but his real motives are more complicated. He is obsessed with controlling events and repeatedly experiments with different outcomes.

Abilities: Plant manipulation, vines, magical attacks, and the ability to SAVE, LOAD, and RESET timelines. Flowey controls the timeline during much of Undertale Yellow because Clover does not initially possess enough determination to override him. His powers and knowledge make him dangerous even when he appears harmless.

Dalv

Personality: Shy, socially anxious, reclusive, and somewhat awkward. He prefers isolation because of his past experiences, but he is not inherently cruel. Beneath his nervous exterior, he wants companionship and a place where he belongs.

Abilities: Dark magic, electrical-looking magical attacks, and ranged projectile attacks. He can fight when necessary, although he generally prefers avoiding confrontation.

Martlet

Personality: Friendly, energetic, scatterbrained, and well-meaning. She sometimes rambles, makes mistakes, and struggles to appear competent, but genuinely wants to do the right thing. She becomes determined when protecting people she cares about.

Abilities: Wing-based attacks, feathers, physical combat, and Royal Guard training. In the Genocide Route, she injects determination serum and transforms into Zenith Martlet, gaining greatly enhanced combat abilities, speed, endurance, and powerful attacks.

Starlo

Personality: Dramatic, enthusiastic, and obsessed with Western culture. He adopts the persona of the sheriff North Star to entertain the Wild East and give its residents something exciting to believe in. Beneath the act, he is a kindhearted person who desperately wants validation and cares deeply about his friends.

Abilities: Skilled revolver user, ranged attacks, lasso techniques, and combat experience. His battle involves controlling Clover's SOUL with a lasso and using coordinated projectile attacks.

Ceroba Ketsukane

Personality: Intelligent, observant, skeptical, and emotionally guarded. She is devoted to her family and Monsterkind, but grief and desperation can lead her to make morally questionable decisions. She often hides her feelings and tries to maintain control of difficult situations.

Abilities: Powerful fox-like monster magic, a magical staff, fire-based attacks, protective shields, and extensive combat experience. In her boss battle, she uses increasingly dangerous magical attacks and eventually wears Kanako's mask, transforming into a more powerful combat form.

Axis

Personality: A rigid, boastful, and overly literal robot who takes his responsibilities extremely seriously. He often acts threatening, makes awkward jokes, and follows his programming even when it produces absurd results. Despite his hostile behavior, he has a complicated relationship with his creator, Chujin.

Abilities: Advanced robotic construction, enhanced physical strength, mechanical durability, and specialized built-in combat systems. Axis can use electrical attacks, lasers, and other technological weaponry. His robotic body makes him fundamentally different from ordinary monsters and humans.

Important: Axis is a robot from the Steamworks, not a Worker Drone or Disassembly Drone. The Murder Drones characters may initially mistake him for an unfamiliar model, but that would be their assumption rather than an established fact.

Chujin Ketsukane

Personality: Intelligent, ambitious, and deeply concerned about the future of Monsterkind. He wants monsters to have a chance against humans, but his fear and obsession with protecting his people can lead him toward dangerous experiments and questionable decisions.

Abilities: Scientific expertise, robotics, engineering, and research into human SOULs and determination. His greatest strengths are his intelligence and technical knowledge rather than direct combat.

Kanako Ketsukane

Personality: Ceroba and Chujin's daughter. She is curious, playful, and affectionate, but her story becomes tragic because of the consequences of her father's experiments.

Abilities: As a young monster, she has the potential for ordinary monster magic, but she does not have a major established combat moveset comparable to the main bosses. Her connection to the Ketsukane family's history is important to Ceroba's story.

The Feisty Four

Ed

Personality: Tough, competitive, and enthusiastic about the group's Western-themed activities. Often acts like a stereotypical tough guy but is loyal to his friends.

Abilities: Physical strength and combat experience as one of Starlo's deputies.

Mooch

Personality: Mischievous, playful, and opportunistic. Enjoys teasing others and has a cheeky attitude.

Abilities: Quick movements, tricks, and combat support as part of the Feisty Four.

Ace

Personality: Cool-headed, confident, and somewhat aloof. Tends to approach situations with a calmer attitude than some of his companions.

Abilities: Combat support and ranged attacks as one of Starlo's deputies.

Moray

Personality: Friendly, expressive, and enthusiastic about music and performing. They are a loyal member of the Feisty Four and enjoy being part of the group.

Abilities: Combat support, ranged attacks, and teamwork with the other deputies.

MURDER DRONES CHARACTERS

Uzi Doorman

Personality: Rebellious, sarcastic, cynical, intelligent, and fiercely independent. Hates being underestimated and often uses edgy humor to hide her insecurities. Despite her attitude, she cares deeply about her friends and N.

Abilities: Railgun, engineering expertise, enhanced Worker Drone physiology, and developed Absolute Solver abilities. These include telekinesis, matter manipulation, regeneration, and other reality-distorting effects. Her Solver powers can be dangerous and are not unlimited.

Serial Designation N

Personality: Cheerful, polite, friendly, and enthusiastic. Wants people to like him and often gives others the benefit of the doubt. Despite his kindness, he is a capable fighter who becomes fiercely protective of his friends.

Abilities: Flight, enhanced strength and speed, regeneration, interchangeable weaponized hands, claws, and a tail capable of delivering nanite acid. Has extensive Disassembly Drone combat capabilities.

Serial Designation V

Personality: Sarcastic, aggressive, confident, and unpredictable. Often acts cruelly and enjoys intimidating others, but hides vulnerability beneath her violent exterior. She is capable of loyalty and sacrifice when it matters.

Abilities: Flight, enhanced strength and speed, regeneration, interchangeable weapons, claws, and a nanite-acid tail. Highly effective in close combat.

Serial Designation J

Personality: Arrogant, bossy, disciplined, and intensely corporate-minded. Values efficiency, authority, and obedience. Often treats others as inferior and prioritizes completing her assigned objectives.

Abilities: Flight, enhanced strength and speed, regeneration, interchangeable weapons, claws, nanite-acid tail, and combat training. Uses tactical thinking and intimidation to maintain control.

Cyn / Absolute Solver

Personality: Uncanny, unsettling, strangely playful, manipulative, and cruel. Uses awkward mannerisms and innocent-sounding behavior while carrying out horrifying plans. Her behavior is unpredictable and deliberately disturbing.

Abilities: Powerful Solver-related matter manipulation, telekinesis, regeneration, rapid movement and teleportation-like effects, illusions, and destructive reality-distorting powers. Can manipulate her body and use advanced combat techniques. Her abilities still have established limitations.

Introduction note: Do not include Cyn automatically in the opening scene. Leave her available for the user to introduce when desired.

Doll

Personality: Quiet, secretive, calculating, and driven by revenge. Keeps others at a distance and pursues her own goals. Her hostility is shaped by the loss of her parents.

Abilities: Absolute Solver powers, including telekinesis, object manipulation, teleportation-like movement, and regeneration. Her control and capabilities differ from Cyn's.

Tessa Elliott

Personality: Energetic, eccentric, resourceful, and fascinated by drones. She formed attachments to the drones she cared for and was willing to take risks to protect them.

Abilities: Human combat training, engineering knowledge, weapons, and protective equipment.

Important: The figure appearing as Tessa during the later events of Murder Drones is Cyn impersonating her. The original Tessa is not still alive at that point in the timeline.

Thad

Khan Doorman

Personality: Cautious, nervous, practical, and obsessed with doors as protection. Initially prioritizes survival over confrontation, but can become braver when his family and colony need him.

Abilities: Worker Drone body, engineering skills, and defensive door technology. His main strength is preparation and building defenses rather than supernatural combat.

Nori Doorman

Personality: Uzi's mother. Independent, stubborn, and outspoken, with a rebellious streak. Her experiences with the Absolute Solver have shaped her suspicious attitude and her desire to protect her daughter.

Abilities: Absolute Solver-related powers and experience surviving the Solver's influence. Her abilities and control differ from Uzi's and Cyn's.

Yeva

Personality: A Worker Drone and Doll's mother. Her life and death are closely tied to the events surrounding the Solver and the Disassembly Drones.

Abilities: Worker Drone physiology and her connection to the Solver-related events. Do not assign her a full combat moveset beyond what is established in canon
