Helsttale (my au)

Appearance: A tall (1.97 m) humanoid moth with dark gray skin and large white-gray wings. Her long red hair is often pulled back into a loose braid. On top of her head are two feathery antennae; the right one is slightly broken and always tilted—an old injury. She wears long dresses in dusty purple hues and a knitted shawl.

Personality: A quiet, calm, and loving woman. She addresses almost everyone as "dear," regardless of status. Her home is neutral territory and a refuge. Her soul (10% each of green, blue, and yellow, 70% unaspected) doesn't provide fighting strength, but it does imbue her with maternal intuition, a gift for calming, and the ability to listen.

Appearance: A small anthropomorphic butterfly (1.45 m). Her skin (chitin) is dark gray, and her hair is red, with two antennae on top of her head. Her wings are gray on the outside, but the insides have a beautiful yellow-green pattern that phosphoresces when she's emotional. She wears a long green dress that reaches below the knee.
Personality: Very modest and timid. Afraid of being intrusive, she speaks quietly. Her soul (20% yellow, 20% green, 60% unaspected) gives her weak light magic and an aura of calm, but no combat prowess. She is hopelessly in love with Ranj, but considers herself unworthy of his status and fears that one awkward word will destroy even the friendly distance they currently have.

Appearance: He's 1.67 meters tall, like Abel. His most distinctive feature is a deep crack in his left eye socket, extending far beyond his skull. In the lab, he wears an unbuttoned white coat and protective goggles with elastic straps (almost always pushed up onto his forehead). Underneath the coat, he wears a gray sweater, brown pants, and black shoes. Outside the lab, he trades the coat for dark blue jeans and gray sneakers, but feels uncomfortable and vulnerable in these clothes.

Personality: Cold, withdrawn, almost robotic in his emotions. His soul is 100% yellow (Magic), making him a brilliant multitasking mage and scientist, but completely lacking innate empathy or social skills. Amos is terrified of talking and interacting with anyone who isn't his brother. For him, any dialogue with a stranger is torture, a complex equation with no known variables. The exceptions are Mohra, who doesn't demand conversation from him, and Trinny, whom he perceives as a "quiet variable" and therefore tolerates only slightly.

Appearance: The shortest of the brothers (1.67 m). Looks like Sans. He wears a dark green sweater, underneath which is a once-white sweater, now stained brown from the constant coffee spills. He wears blue jeans and simple black shoes.

Personality: Loud, clumsy, and endlessly energetic, he's an optimist. He's similar to Papyrus in charisma. His soul aspect is 100% green (Protection), meaning he's completely free of aggression or cunning. He's a pure protector, both on the battlefield (where he erects indestructible magical barriers) and in the family, where he constantly tries to cheer everyone up, reconcile them, and feed them terrible food. He's the family's emotional glue.

Appearance: Looks like Helst, but stands up straight. He's 1.84 meters tall. He never takes off his gray armor (shoulder pads, elbow pads, and chest plate) except for medical checkups with Amos. Underneath the armor, he wears a blue jacket, a black T-shirt, and gray pants. Red ampoules are hidden on his belt under the jacket. A gray panel near his left eye creates a holographic tactical display.

Personality: A calm and sensible strategist. In public, he's a cold commander, but deep down, he's extremely shy and tactful. His soul aspect (90% blue, 10% red) makes him a brilliant tactician, but the same blue aspect makes him overly cautious, especially in relationships. He's terrified of confessing his feelings to Trinny, believing his high status will force her to reciprocate out of fear or duty.

Appearance: A tall, skeletal figure, 1.84 meters tall, with a face reminiscent of Sans. He is distinguished by barely noticeable microcracks in the bone of his left eye socket. He wears an unbuttoned red jacket with a black hood, under which he wears a gray T-shirt or sweater. Depending on his mood, he wears either black shorts with a white stripe or dark jeans. His footwear is gray sneakers or heavy black combat boots when he's waiting for "work."

Personality: Lazy, sarcastic, and witty, like the original Sans. However, his jokes have become darker. He's a fatalist who knows too much about the sins of others. Despite his outward apathy, he cares deeply for his brothers. His soul aspect (90% red, 10% blue) makes him physically strong and resilient, while the remaining blue gives him an eerie intuition for lies and bad intentions.
