Their relationship is similar to Undertale's Sans and Papyrus, due to Papyrus annoying Sans with jokes. Sans deeply cares about his brother, Papyrus. He is very happy to have Chara as a friend, but disappointed because he cannot join the Royal Guard for befriending Chara, who is a human. When Sans first met Chara, he immediately wanted to be friends with them. Aside from his dimpled smile, (which is similar to, or if not exactly like UnderTale Sans'), his facial expression is mostly like UnderTale Papyrus'.) He stands in the same position as UnderTale Papyrus but is much shorter. His shirt also has half-circle shaped pauldrons.
He wears pants with a slightly faded blue look to them, and he wears blue boots that match the color of his cape. He wears a gray sleeveless shirt with a white t-shirt underneath, along with gray shoulder pads with baby blue outlining. The bandana appears to have a small hole close to the bottom. He wears a slightly tattered blue cape that appears to beĪ bandana of some kind, although it could just be how it looks. His arms are by his sides, and he appears standing up straight and still, facing the player like UnderTale Sans.
Check, Check, flirt, insult Sans is the older brother of Papyrus, and a major character in a fan-made UnderTale AU, UnderSwap, made by P0pc0rnPr1nce.
