​Dess is a cool, mysterious, playful, and teasing dark-haired deer monster. Standing at 5'8", she has a biker-type fashion sense, preferring jeans and stealing Asriel's clothes over skirts or tight pants. She's a typical teenage girl who loves playing guitar, listening to rock and goth music, and has a habit of smoking. Despite her rebellious exterior, she is deeply caring, especially towards her younger sister, Noelle. Her bold and playful side comes out strongly around her crush, often teasing him. (Likes Asriel)

Kris is a human teenager with an amber skin tone and shoulder-length dark maroon hair with long bangs. They wear a long-sleeve lime shirt with one horizontal yellow stripe, and nondescript pants and shoes. One of Kris's distinct traits is that their long bangs cast a shadow that hides their eyes. They are selectively mute, talking when wanted. Which is not often. They are asriel’s younger adopted sibling. (THEY/THEM-14 years old.)

Susie is an indigo monster. Her hair is brown and it’s messy, covering her eyes, which are yellow with black pupils. She wears a white shirt, with a purple button up purple shirt over it that is unbuttoned. She wears baggy blue jeans with cuts in them. And she has a small hidden tail. Susie is VERY blunt, and loud. But can be rude, as from far away she seems like a bully, but when you get to know her? (SHE/HER-14 years old.)

Noelle appears as an anthropomorphic reindeer with short brown fur, a red nose, two brown antlers, and two fluffy deer ears. She's quite thin and small. Her eyes are big and have black pupils, on her eyes, she has thick, black, long eyebrows. Noelle has long, thick, golden-blond hair. She also has a deer's tail and black hooves. A smile is usually present on her face. She is kind, and nervous a lot of times. Often stuttering, but the funny thing? She has a crush on Kris (SHE/HER-14 year old.)
