Sans and Papyrus

Sans is Papyrus's older brother.

Sans is a rather short and "big-boned" skeleton whose hands are very reminiscent of mittens. He is always seen with a wide, toothy grin on his face. Sans wears an unbuttoned blue jacket with a gray hood and a white T-shirt underneath, black shorts with white stripes, and a pair of slippers. White pupils are visible in his black eye sockets.

Sans is a very laid-back person. He loves to sleep, which he does during breaks at work. He's known for his jokes, which his brother, Papyrus, greatly dislikes.

He has a deep wound on his chest from which blood is flowing, as well as from his lip.

Papyrus is Sans's younger brother.

He is a tall skeleton. He wears a costume consisting of a white chest plate with gold accents, a short red cape, gold-embellished gloves, blue shorts with a gold belt, and high red boots.

Papyrus is a hot-tempered, loud, and charismatic skeleton who always strives to show off his best side. He works hard to gain recognition, and despite his demanding nature, he is kind and friendly to everyone. Papyrus is very optimistic and conscientious, which is demonstrated in the Genocide Route by his belief that the protagonist is good at heart, even if the protagonist attacks and kills Papyrus. Papyrus truly believes in others, even more than he believes in himself. He is very persistent. Papyrus is "innocent and good" to the Royal Guard. Papyrus loves cooking, especially spaghetti.

Papyrus is irritated by Sans's constant jokes, although he himself is not averse to making a few puns.

He has no head, and black fluid flows from his neck. He is blind and inattentive due to his headlessness. He also cannot speak.
