**Sans** is the older brother of Papyrus and lives with him in Snowdin. He runs food stands in various parts of the underground and is a regular at Grillby's.

## Appearance

Sans is a short, chubby skeleton with a "top heavy" rounded skull, and always has an unamused expression. His telekinesis pupil is always on, glowing a torch red. He also has sharp teeth, with one of them being his signature gold tooth.

He typically wears a carmine red turtleneck sweater under a black coat with a furry, spiky hoodie that appears to have flame-like plumes, carmine red gloves, and black basketball shorts with golden trimming. He also wears rings on his fingers hidden by his gloves, yellow socks, and red sneakers.

His transformation involved his pupils changing over time, the left one slowly turning red and the right eventually disappearing all together. Additionally, his teeth eventually turn sharp. He seems to have always had the gold tooth from the beginning, though unknown if he was born with it.

## Personality

Sans is a somewhat laidback skeleton who's always on edge and overall just unamused about everything. He's very bitter about the situation he and his brother are in, blaming himself for their terrible life under Asgore. He is often very sarcastic and is extremely tired. Despite his tiredness and bitterness, Sans strives to be the cool and collect brother.

Sans appears to like annoying others, especially Papyrus. He wears shoes because he likes the squeaking noise it makes since everyone hates it.

As implied by Fella and Papyrus, Sans is capable of severe harm. Paired with his instability, this makes Sans very dangerous and technically the most powerful, which comes with the consequence of hurting himself the most.

## History

### Pre-UNDERFELL

At some point, Sans joined and worked for the Royal Scientist, Gaster, along fellow co-worker Alphys. It is unknown when exactly he stopped working at the lab, but it can be presumed it was around after Gaster disappeared. It is unknown if he quit due to the previously mentioned event.

At another point, Sans angers Asgore in some way, nearly getting his skull crushed. However, Papyrus intervenes and saves his life. Consequently, Asgore forces and manipulates Papyrus into the Royal Guard, but then punishes him (for defying him when he blocked Asgore from killing Sans) by giving him deep scratches down his left eye socket, scarring it. This is what was the "final push" for Sans, thus making his magic becoming uncontrollable and his mental state unstable, extremely distressed at what had happened.

## Relationships

### Papyrus

Papyrus is Sans's younger brother. Though not negative, Sans and Papyrus are not close and are kept distant by Sans himself due to guilt and troubling thoughts, preventing them from having a close sibling relationship. However, they care for each other deeply; Papyrus cares deeply for his older brother and is willing to go as far as to join the Royal Guard to keep him safe. Papyrus will protect him when needed and is willing to fight anyone who messes with Sans. The two often bicker, but they never get too violent. Papyrus wishes to help Sans, but the latter refuses his help out of stubbornness. Sans blames himself for his and Papyrus's bad living situation, his magic becoming unstable and uncontrollable when the latter got his scars from defending him.

Despite them not being close, Sans loves Papyrus and deeply cares for him. However, if Papyrus were to get in trouble, he'd be there to help him. He also likes to annoy Papyrus, often playing naïve.

### Toriel

Toriel is a close friend of Sans. He loves talking and being around her, hanging out with her presumably often.

### Asgore

Asgore is Sans's superior. It can be presumed Sans resents and despises Asgore deeply for what he's done to him and his brother. He was nearly killed by Asgore at least once for reasons unknown, but can presumed that he had angered or annoyed Asgore in some way. He was willing to attempt to attack him after seeing him put a deep scar into Papyrus's eye, despite Asgore intimidating him.
