Sans Gaster

 Sans  is the older brother of Papyrus. Sans is the more intellectual yet lazy one of the two Skeleton Brothers

Appearance
Sans appears as a short, paunchy skeleton with a wide toothy grin, glove-like hands and large eye sockets. He wears an unzipped blue hoodie, a white shirt, black shorts with white lining, and a pair of salmon-colored slippers.

Personality
Sans is laid back and flippant, often sleeping on the job and taking breaks. His laziness is a combination of fatalism and apathy. He is also observant; Sans can read someone's expression and can often tell when they have already done certain tasks.
