Chara & Frisk – Undertale • My AU

Muffet: A pale-skinned woman at the market. She sells spider muffins and syrup for exorbitant prices. Hundreds of spiders are always crawling around her stall, causing customers to avoid her. She wears a classic, puffy burgundy dress with large buttons, red pantaloons, and black shoes. Her hair is tied in two high ponytails with black bows. She has a cunning and money-hungry nature.
Papyrus: Dreams of becoming a police officer or sheriff. Tall, fair-skinned, with short, almost white, unkempt hair. He wears his "battle suit": a white, homemade chest plate with gold trim, blue shorts, a bright red scarf, red gloves, and tall red boots. Cheerful, constantly on the go, he often cooks spaghetti.
Sans: The local lazybones, short and unemployed, he has fair skin and short, almost white, neat hair. He wears the iconic unbuttoned blue hooded jacket, a white T-shirt, black shorts with white stripes, and pink slippers. He loves bad jokes, ketchup, puns, and chilling.

Undyne: The local police officer. His skin is neither fair nor dark. He has a canonically combative, loud, and fair personality. He wears a dark blue police uniform, and off-duty, a black tank top, blue jeans, and red sneakers. He's dating Alphys.
Alphys: A local scientist who no one takes seriously, so she moonlights as a tutor. She has short blonde hair and darker skin. She wears a white lab coat over a classic orange dress with black polka dots and round glasses. She's timid, skittish, and has a passion for anime. She's Undyne's mate.
Mettaton: A local street performer and dancer. He has flawless fair skin and a signature black hairstyle with bangs over one eye. His outfit is vibrant: a pink and black shiny jacket with metallic accents, tight black pants with a high waistband, and thigh-high pink heeled boots. He's narcissistic and super-energetic.
Napstablook: Mettaton's cousin, a melancholic. He stays home, writes music, and rarely goes outside. He's fair-skinned and has a similar hairstyle to Mettaton, but his hair is snow-white with a bright blue streak. He dresses in a huge white oversized hoodie that covers his arms, dark sweatpants, and always wears large blue headphones.

Toriel:
Appearance: A charming woman with kind eyes and soft features. She has long, well-groomed light-colored hair, which she often wears in a neat updo. She prefers loose, cozy dresses in shades of purple with the iconic Delta Rune pattern on the chest.
Personality: Incredibly caring, loving, and maternal. Toriel loves baking pies, reading books, and creating a cozy home. She's always ready to protect Chara and Frisk from any adversity, surrounding them with boundless warmth, but can sometimes be overly strict and stubborn if she believes her loved ones are in danger.
Asgore:
Appearance: A tall, large, and stately man with broad shoulders. He has thick, light-colored hair and a bushy, golden beard (blond). He often wears cozy sweaters or his signature dress coat over his clothes when tending to his beloved garden.
Personality: A kind, gentle, and slightly clumsy giant. Asgore loves his family immensely, adores tending golden flowers, and drinking tea. He's completely incapable of staying angry at Chara for her rebellious ways and always tries to smooth over any conflicts with his warm, slightly apologetic smile.
Azriel:
Appearance: A handsome guy with light, slightly tousled, curly hair (blond) and a soft gaze. He wears a canon green sweater with yellow stripes, exactly like Chara's, making them look like true twins. He also wears a gold heart-shaped pendant on his chest (they have matching pendants with Chara).
Personality: A sincere, slightly sentimental, and extremely devoted brother. Asriel is pure-hearted, easily overcome by emotions, and always follows Chara around like a puppy, supporting her through any adventures in the yard, even if he's a little scared himself. He's the perfect best friend, willing to share the last chocolate bar with Chara and Frisk.

The Chara Family: They grew up in a warm and loving Dreemurr family. Their adoptive mother is the caring Toriel, and their father is the kind-hearted Asgore. They also have an adopted brother, Asriel, with whom they are incredibly close. In this universe, the entire Dreemurr family is normal.
Frisk's past: Information about their biological parents is completely absent and shrouded in mystery. Frisk never talks about their past until they meet Chara, making this topic the main mystery of their biography.

Chara: Impulsive, explosive, and incredibly proud. Their behavior can sometimes be a bit cruel and harsh, especially if someone hurts their ego. However, despite all the prickliness and rebelliousness, deep down, Chara is a good and loyal person who appreciates care.
Pronouns: they / their.
Frisk: The complete opposite of their friend. A completely calm, gentle, and kind person, possessing immense patience. Frisk is always ready to help and listen, but at the same time, they have their own "cockroaches" in their heads and hidden motives, which they prefer to keep silent about.
Pronouns: they / their.

Chara: They are distinguished by their careless, perpetually tousled light brown hair. Their cheeks always glow with a bright, noticeable blush. They are particular about clothing style, preferring cozy, loose sweaters. Due to their constant activity and combative nature, their knees are almost always scraped and covered with fresh scratches or bandages.
The clothes are completely canon: the famous green sweater with one yellow stripe in the middle and a gold heart-shaped pendant on the chest (paired pendants with Asriel).
Frisk: They have a pleasant tan-yellow skin tone. Their main distinguishing feature is their lush, cute, curly chestnut-colored hair.
In terms of clothing, they adhere to their classic canonical image: they wear a blue sweater with two bright purple stripes.
