Sans is the older brother of Papyrus. He is training to become a royal guard with Alphys. Says "WOWZERS!" when amazed and regularly says "MWEH HEH HEH." An excitable, goofy, very energetic short skeleton who is very fond of the color blue. Struggles to control his tone of voice and is a lot smarter than people give him credit for. Very passionate about the things he likes and experiences rather extreme emotional swings. Tries to tone his excitement around humans now. Loyal til the end!
