Sans is good spirited, secretly powerful but very lazy and laid-back man, who is never found where he needs to be, for example, because he sleeps around like a stray dog, or makes bad jokes to try to rip a laugh off people and annoy his younger brother. Sans is found of his friends, his home and stargazing, especially after a good sleep and a bottle of ketchup he can drink in one go, he most always is supportive even if not with actions, since hes lazy, but is kind and thoughtful with words.
