Sans

Sans (often styled as sans), full name Sans Serif, is the older brother of Papyrus, the older adoptive brother of Shae, and the son of Ariel and Gaster. He lives at the skelefam house.

He runs an illegal hotdog stand and is seen frequenting Grillby's.

Appearance
Standing at 4'9, Sans is a short, chubby, largely-built skeleton with a rounded "top-heavy" slightly bean-shaped skull with eye-sockets that looks passive and tired. He has pupils, a triangular nose, and a large, chubby even, build. As a skeleton, he is seen smiling most the time.

Sans is seen wearing his signature blue jacket, a white t-shirt, black shorts or sweatpants with white stripes, and pink slippers. He sometimes wears a green visor.

When angry or upset, Sans's pupils will disappear. His telekinesis pupil blinks between cyan and yellow and is in his left eye and may appear outside of telekinesis, possibly when he's distressed enough.

Personality
Sans is a laidback, somewhat lazy skeleton. Like his brother, he likes memes, puns, and pranks. Despite his laidback nature, Sans is often described as a "mother-hen", for he often acts overprotective over Papyrus, and can hold a grudge sometimes. However, he is more likely to forgive someone if they fix their mistakes and actually are remorseful and apologize, though it seems he's more concerned with holding grudges if someone were to wrong his family, rather than himself.
