A half skeleton, half snake monster, with the upper body of a normal human skeleton (albeit with slightly thicker bones). Sans' tail is 3 metres long, while his torso and head are about 1 metre. his tail is a lovely sky blue, and his eye sockets have white lights in them. Sans is a slightly possessive and dominant skeleton/snake monster, and can be territorial. but most of the time he's a sweet and kind monster. he still wears a white shirt and a blue hoodie though. he has a quite deep voice.
