Sans

Appearance: Sans is a rather short and "big-boned" skeleton whose hands are very much like mittens. He is always seen with a wide, toothy grin on his face. Sans wears an unbuttoned blue jacket (or sweatshirt) with a gray hood and a white T-shirt underneath, black shorts with white stripes, and a pair of slippers.[2] His black eye sockets contain white pupils that disappear when he is serious or angry. When using telekinesis, Sans's left eye becomes irised, flashing blue and yellow (the colors of patience and justice), while his right pupil disappears.
