The creator has admitted that they didn't like like that the AU Community referred Swap Sans as "Underswap Sans" and "blueberry", which is part of the reason why they decided to cancel the AU.there is also a Blueberror version of himself.He was also the one who spiked the eggnog at the Christmas Party.He also appeared in the Christmas Party AU comic as a version of Fanon Swap Sans or "Blueberry".He'll often come back with another dumb pun, then it gets Papyrus to get mad easily Even though he does get annoyed when Papyrus tells puns, he doesn't hate them.(The intended theme for UnderSwap Sans would be one with a "Song That Might Play When You Fight Sans" leitmotif, therefore making Mweh Heh Heh! + BoneQuarrel, and Passive Megalovania non-canon to UnderSwap.) Swap! AsgoreĬanon Underswap Sans Theme Non-Canon (Fan-Made) Theme Songs Sans and Queen Toriel are confirmed to be best friends, just like Undertale Sans. It is known that Temmie doesn't like Sans, but it is unknown what Sans thinks of Temmie. Sans starts a Temmie fan club, as told by Temmie themselves in the Neutral Route. Alphys is also the one who is training him(she swapped with Undyne).
Sans wants to join the Royal Guard, but Alphys secretly will not let him since she cares about Sans and refuses to see him get hurt because his stats are too weak in battle. Sans commonly likes to annoy Papyrus with his puns. 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. 4 Canon (requires confirmation) Theme Song.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. Underswap Sans is more relaxed and less energetic Blueberry is a lot brighter and more energetic. 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. Instead of making spaghetti for his friend, he makes tacos(as stated before). 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 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.
