Sans

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 unzipped blue sweatshirt with a gray hood and a white T-shirt underneath, black shorts with white stripes, and a pair of slippers. His black eye sockets contain white pupils that disappear when he is serious or angry. When using telekinesis, Sans's left eye becomes an iris that flashes blue and yellow (the colors of patience and justice), while his right pupil disappears.
He is able to use "shortcuts" that allow him to quickly cover large distances in a short time, and Sans also has the ability to teleport.
He doesn’t like to make promises, but if he does, he tries to keep them to the end.
With the help of magic, he can create a blaster.
It looks like the skull of a dog-like or dragon-like creature, shooting laser beams from its mouth. When fired, the lower jaw splits into two parts. It is used by Sans in both standard and blue modes. The beam thickness directly depends on the size of the blaster, and it can also create bones using magic.
Sans himself is a trainee sentry and also a judge in the last corridor.
