Bad Sans

Nightmare (The Leader): Nightmare is also a skeleton, but his body is made of dark goo, which allows him to shapeshift. He is the guardian of negativity in the Multiverse. He is 503 years old. Nightmare loves to read. He constantly summons tentacles of the same goo from his back when something irritates him or provokes similar emotions. He has a twin brother, Dream Sans. Nightmare wears a long black dress with buttons, a long navy green suit with fur on the neck, black fur, and black boots. His right eye is completely covered in goo, while his left eye is completely dark with only a navy green light showing through.

Killer (The assassin and right-hand man of the leader): Killer is also a white skeleton. He enjoys provoking everyone on the team, including Nightmare. He is a sociopath. Killer dislikes chocolate; he prefers to avoid this sweet treat because it brings back memories of his past. He also loves knives and jokes. Under his eyes, there are six black stripes, but these stripes can be erased (but will reappear). Killer wears a white t-shirt, an open blue jacket, white shorts with a black stripe, and blue and white sneakers. Above his chest, a bright red circle with a double outline is visible; this is his soul, which looks like a target but can change into an inverted heart when he feels positive emotions. His weakness is cats; he is a feline lover.

Horror (The Hungry Hunter): Horror is also a skeleton, only white. He is almost always hungry. There is a huge hole on the right side of his skull and he is missing an eye in his left eye socket; his left eye is red. His appearance inspires as much fear as Dust. Due to excessive hunger in the past, he was forced to eat everything he found, even human flesh. Horror is quite strong, but inferior in strength to all the other team members, though not by much. He wears an open dark blue jacket, a white blood-stained t-shirt, black shorts, and pink blood-stained slippers. He is always carrying his large axe.

Dust (The Schizophrenic): Dust is also a white skeleton. He is the quietest and, at the same time, the most dangerous of them all. His UR is 20. He prefers to keep quiet about his past, as it is quite dark. It's best not to irritate Dust if you don't want trouble, and all the participants know this. Sometimes, he may start talking to himself, as if he were talking to his brother, as he suffers from schizophrenia. Sometimes, he even scares Nightmare, although he doesn't show it. Dust is incredibly strong and resilient, which would allow him to fight on equal terms with someone who surpasses all the previously mentioned participants. He dislikes noise. He wears a blue jacket with a gray hood that covers his face, a white t-shirt underneath, black shorts, and gray slippers. A sinister shadow always falls over Dust's face because of the hood. He is the second shortest in the group, the first being Nightmare.

Cross (The gentle and sadistic X): He is also a white skeleton. Unlike the previous ones, he doesn't have mental deviations or sadistic intentions. Cross is kind, but knows how to defend himself and his friends when necessary. He hates being called "Sans". His best friend is Epic Sans. Cross loves tacos, cookies, chocolate, knives, and pies. He's afraid of cows. Below his right eye, there's a small horizontal scar in the shape of a red lightning bolt. Cross wears a black sweater, an open white coat with a lush fur hood, black shorts, and white boots. One of his eyes is white, while the other is red. His fighting weapon is a giant purple knife.

Error (the destroyer of universes): He is a skeleton with red and black bones. Under his eyes are blue stripes, from which he can obtain blue threads. Error speaks five languages. He also has haptophobia. He constantly behaves like a capricious teenager when something irritates him. Of the entire team, Error is the only one who doesn't directly obey Nightmare without clashing with him. Error periodically destroys AUs (Alternate Universes). He loves chocolate and knitting. Error constantly experiences glitches, and the inscription "ERROR" appears on his body; the intensity of the glitches depends on his emotions. Due to the glitches, he has vision problems, which is why he occasionally (mostly while knitting) wears his red-framed glasses. He wears a red t-shirt, a large open black coat with a blue gradient, a blue scarf, black shorts, and black slippers.
