Sans Gaster is the older brother of Papyrus and a major character in the Underearth Arc. Sans is the more intellectual one of the two oldest brothers, though his youngest brother, [REDACTED], is much smarter than Sans.
Sans is an easy-going type person, and is generally seen as very lazy. In reality, he's just way over-worked, and is always tired.
Sans and Alphys don't really know about each-other's existence(except on social media) in this arc. They meet at the end of the No-Kill route.
Sans doesn't know much about The Shadowy Figure, as he just occasionally appears to inform Sans of future events or scientific inquiries.
Papyrus is the younger brother of Sans. Sans looks up to, and looks after his brother.
Sans and Toriel crack jokes at each-other through the door to the Ruins of Home.
Undyne trains Sans's brother in order to become part of the Royal Guard. She is also his employer.
