Sans

Personality
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."[1]

Appearance
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, a white t-shirt underneath, black shorts with white stripes, and a pair of slippers. He has white dots in 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 a skeleton wearing a blue jacket, black shorts with white stripes, and white slippers. Prior to the events of Undertale, he had moved to the settlement in Snowdin from an unknown location with his brother Papyrus.[citation needed] Papyrus was hired as a royal guard trainee sentry and forced his brother to help in his quest to capture a human.[1]
