Sans is the older brother of Papyrus, and is a major character in the Undertale AU, UnderSwap by P0pc0rnPr1nce, in this AU, instead of being a laid back, lazy, and smart skeleton like in Undertale, Sans has a role in the story and personality more similar to Papyrus, and with Papyrus the opposite happens.

Sans is a fairly short and overweight skeleton with a large mouth and eyes, tall nose, and eyebrows, along with that his pupils are two hollow blue circles inside each other.

Sans wears a ripped scarf with a long cape, along with grey armour with cyan trims and a white shirt underneath, he wears dark blue pants that tuck into his blue boots with dark blue soles and heels.

Unlike Undertale Papyrus, he does not wear gloves of any kind, and has his skeletal hands out.

He's also biologically different from Undertale Sans, with his mouth being able to open when talking, showing a bright cyan tongue the same colour as his eyes.

We know very little about UnderSwap Sans' in battle actions beside the fact he seems to be more animated then Undertale Papyrus, holding a cyan bone and jumping around in the first art of the AU.

When killed, instead of his body turning to dust and his head falling to the floor akin to Undertale Papyrus, he begins to blood a red, blood like substance, while on his knees.

The human in UnderSwap has no information on them, but it is highly head cannoned that Frisk swaps with Chara.

Sans and the humans relationship also has very little information on it, what is known is that he sets up multiple puzzles for them, wants to capture them, can date them, and in genocide, refuses to fight them, instead offering them a hug.

Sans and Papyrus' relationship in UnderSwap is the same as in Undertale except swapped, with Sans being amazed by his brothers behaviour by being active, he's also unhappy that his brother is taller than him, leading to Papyrus to often be hunched over.

Sans and Alphys' relationship in UnderSwap is the same as in Undertale, with Alphys wanting to let Sans into the Royal Guard, but is unable to, in UnderSwap, it is because Sans's stats are too low, causing him to be very fragile.

Sans and Temmie likely have the same relationship as Papyrus and Flowey have in Undertale

Sans and Toriel's relationship is most likely similar to that of Papyrus and Asgore in Undertale, though they may also possibly be closer in UnderSwap
