sans

Sans is the older brother of Papyrus and a major character in Undertale. He first appears in Snowdin Forest after the protagonist exits the Ruins. Sans is the deuteragonist of the Neutral and True Pacifist routes, in which he keeps an eye on the protagonist throughout the game. He is also the final boss of the Genocide Route.

Sans appears as a relatively short and paunchy skeleton, with mitten-like hands. Sans is always seen with a wide, toothy-grin on his face. Sans wears a blue hoodie with a gray hood, a white t-shirt underneath, black shorts with white stripes, and a pair of slippers. He has white dots for pupils in his black eye sockets that disappear when he is serious or angered. When Sans uses telekinesis, his left eye flashes light blue and yellow (the colors for patience and justice) while his right pupil vanishes.

Sans is lazy, often sleeping on the job and taking breaks. His laziness is a combination of fatalism and apathy, as he is aware of timeline resets. Conversely, he suggests that this knowledge could be "a poor excuse for being lazy."

He enjoys being mischievous. Sans primarily acts this way towards those he is in good terms with. His antics range from an assortment of illogical, juvenile, and slightly inconvenient pranks. Examples include Sans "selling fried snow," using whoopee cushions, sharing an unscrewed ketchup bottle, and eye paint on a telescope. He is not above utilizing his teleportation or other magic for practical jokes either. Sans is also fond of making the occasional low-brow puns. He enjoys making others laugh in general, as he also performs at the MTT Resort as a comedian.

After killing Papyrus [his brother], the protagonist continues to kill all the monsters in the Underground. Sans watches them secretly without confronting them directly, hoping they would heed his friendly advice and stop. Eventually, he decides to stop them himself no matter what.

Sans confronts the protagonist in the Last Corridor but does not judge, instead claiming they must have been busy. He starts off by paraphrasing one of Papyrus' statements. Instead of answering, the protagonist takes a step forward.

Next Sans laughs and asks "do you wanna have a bad time?", threatening them with force should they proceed. When the protagonist dismisses his warnings and continue to advance, he fights them.

Before the battle begins, Sans apologizes to the late Toriel for breaking his promise to her.

Sans repeatedly dodges the protagonist's attempts to hit him and retaliates with his relentless attacks, doing his best to stop them.
