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. He is NOT a Yandere despite what arisen from Blueberry and does not have strong feelings for Fell!Sans or Dust!sans, which are common ships used with Blueberry. Blueberry is not canon to UnderSwap and is not the correct portrayal of UnderSwap Sans. He appears to be more cute, innocent, and sometimes more baby-like, unlike the original UnderSwap Sans. However, Blueberry is a Fanon rendition of UnderSwap Sans. He is often referred to as 'Blueberry' by Fans because most of them find him cute, along with the fact that most of his clothing is blue. He also collects Sci-Fi figures instead of action figures. UnderSwap Sans is similar to Canon Papyrus in a lot of ways, but there are also some differences! For example, instead of 'NYEH HEH HEH!' or 'WOWIE!', UnderSwap Sans will say 'MWEH HEH HEH!' or 'WOWZERS!' UnderSwap Sans has a liking for riddles rather than puzzles, and still enjoys puns. His stats are similar to Canon Papyrus', being 20 HP, 20 ATK, and 20 DEF, but this in some (Maybe hard to find) versions, he has the same starts as classic Sans but different role. He is very positive and enjoys making tacos for his friends. However, he is very cheerful and much more energetic than Undertale Sans. A disadvantage of his is that he is almost as weak as Canon Sans, leading to being denied a position in the Royal Guard. His motivations are to capture a human so that he can become an official member of the Royal Guard, a very prestigious job.

Sans is the older brother of Papyrus, and a major character in a fan-made UnderTale AU, UnderSwap, made by P0pc0rnPr1nce.
