Papyrus is a tall, perhaps anatomically inaccurate skeleton, with a skull more vertical and geometric than his brother. Being skeletal, many of his expressions incorporate a toothy grin. His eyes resemble vertical slits; his skeletal pseudo-brows form most of his expressions, as well as the corners of his mouth. He has eyeballs which show at times when he is experiencing strong emotions. Papyrus is a flamboyant skeleton who presents a confident, charismatic image of himself. He is thought to have an egotistical personality, referring to himself as "THE GREAT PAPYRUS," possibly as a way to feel as prestigious as his brother. He works hard and, despite his brash personality, is kind at heart. He is optimistic and brave, and is shown to be considerate and forgiving, even when he gets beheaded. He is also occasionally oblivious and nonobservant, but can be cunning at times. He is thought of to be somewhat naive by other characters, but not dumb. He shows great bravery as even in the face of potentially imminent death, he drops his guard and spares even murderers, hopes of driving them down a better path. Papyrus believes in others just as much as he believes in himself. His confidence in himself and others is so great that he interprets direct insults towards him as the protagonist trying to make themselves look bad so he can hurt them easier, rather than the possibility that they dislike. He cooks spaghetti from time to time, though many characters seem to think that he is not very good at it. One of the reasons for this is because Papyrus never ate spaghetti himself to complete the chef's guidebook to cooking by tasting their creation before serving. He, therefore, cooks spaghetti only because everyone else loves to eat it, indicating he does not play favorites.
