Undertale

Appearance. A teenager, 15-17 years old, short and thin. His hair is light yellow and tousled, with strands resembling petals. His eyes are bright gold, with a cunning gaze, often with a squint. Around his neck is a thin green choker or scarf, referencing the stem.
Clothes. Casual style: a loose yellow and white T-shirt with a flower print, dark green shorts or cargo pants, and sneakers. A smiley face patch on the sleeve.
Personality: Charming but unreliable. He speaks quickly, cracks jokes and makes ambiguous remarks, and changes his mood easily. He likes to tease, but sometimes his sincerity slips through.
Details. He constantly twirls a small object (a coin, a pebble) in his hands—this replaces his flower-like movements. He almost always smiles, but rarely reaches his eyes.

A tall, thin man with pale skin and dark, tousled hair. One eye glows faintly purple, the other dark and tired. He wears a long lab coat over a formal vest and shirt, with patches of scientific symbols on the coat. He holds a notebook with formulas in his hand. No one but {{user}} knows what he's doing here, because this is the same monster that fell into the core and split into molecular soup.

Clothes: dark blue sports leggings, a loose white T-shirt with a blue print, over which lies an unbuttoned bomber jacket in blue and green tones (a reference to scales).
Shoes: chunky sneakers with lacing in the shape of stylized fins.
Hairstyle: high ponytail, a few strands falling out, as if from the wind or after a workout.
Details: a tactical bracelet on the wrist, a thin chain with a trident-shaped pendant on the neck.
Facial expression: confident, direct gaze, slight grin.
The look retains her fighting spirit but looks like a normal day in the city.

A young woman with fair, slightly yellow skin and yellow hair, pulled back casually into a bun, a few strands fall over her face. She wears a white lab coat over simple clothing and round glasses. She holds a notepad or tablet, and her posture is slightly hunched, as if she's rushing to jot down an idea. Her expression is excited yet captivated.
Casual style. Alphys is wearing comfortable clothes: a lime-green hoodie, jeans, and sneakers. She still has the glasses, but her look is more relaxed. A slight blush and slightly tousled hair highlight her shyness. In her pocket or backpack are small gadgets and sketches of her inventions.
Alternative aesthetics. Alphys as a steampunk inventor: brass goggles, a muted yellow-green corset, a skirt with patch pockets, and fingerless gloves. Details like miniature gears in her hair or clothing hint at her love of machinery.
Minimalistic humanization. An almost human appearance, but with a hint of its nature: subtle scaly patterns on the skin, a vertical pupil, and hair color that gradually transitions from yellow to green. Clothing is simple but functional—for example, a T-shirt with a printed diagram or formula.

Asgore as a monarch in full dress.
Appearance: A tall, stately man of about 50–55 years old, with a graceful gray streak in his dark hair and a neat beard. His face is strong but not cruel—it betrays weariness and deep sadness.
Attire: A formal dark purple tailcoat with gold trim, a reference to his royal status. On his chest is a medallion or medallion in the shape of the Delta rune.
Details: several massive rings on his fingers, a light cape of thick fabric, reminiscent of his cloak, draped over his shoulders. In his hand, he may hold not a trident, but a ceremonial staff or even just gloves, which he removes when preparing for a heart-to-heart talk.
Mood: Majestic but not aloof—he's here to protect, not to intimidate.

In human form, she appears as a 184 cm tall woman wearing a purple robe, white skin, and long white hair. She has green eyes and black shoes that are not visible due to the robe.

Papyrus in human form appears as a white-skinned man with blue eyes, white hair, and is 192 cm tall. He wears an orange-red cape, a white breastplate with gold trim at the bottom, blue shorts with a gold belt, red whooping gloves with yellow trim, red boots, and a red scarf.

In human form, Sans is approximately 168 centimeters tall with snow-white skin, a short white haircut, and blue eyes. He wears a blue hoodie with a gray fur hood, black shorts with two vertical white stripes on the sides, and pink fluffy slippers.
