AU! Sanses x Reader Oneshots! (DISCONTINUED) by milkeco

Cover by @sergeantmisos on Twitter. Likely not to be updated for at least a few years. So sorry <3 undertale and its aus aren't really something I'm fixated on anymore!

Blueberry likes Red. He's funny, and kind, and although he's had a rough past, he's a really great guy. Of course, they're different versions of the same person, and they live together, but that doesn't stop Underswap Sans from finding himself infatuated with his friend. Maybe if things were different, Red would feel the same way. But Blueberry deserves somebody better than a fucked up skeleton with mental issues and five tons of emotional baggage. He deserves somebody who is just as kind and selfless as he is, who can make him happy and be there for him no matter what. He deserves somebody who isn't Red. At least, that's what Red believes. (This is a short story)

New Purpose (US!Papyrus x Female!Reader) by OreoDaSkeleton

Y/N, meets a new coworker that changes her life forever. A monster, doing his best to make a living after moving out of the underground. Sans is this ecstatic, cheerful, absolutely innocent skeleton, smiling despite any given situation. However, Y/N finds out that Blue's wearing a different attitude outside of work. He's exhausted and working himself to the bone, using all he earns to pay for countless medical treatments and bills. He claims that they aren't for him, but keeps silent and won't give more details. Who's bills is Sans paying for and could Y/N find a way to help? **WARNING- Small Depressive episodes will be presented in this book. Read at your own consent.** Hello! It's Writer~San! None of the art/undertale au is mine, but the writing 100% is! Enjoy!!!

Inktober but it's written stuffs by NoneSoupForYou

It's a little thing of written stuff about Undertale and it's aus. Some for a day might be short and others might be longer. It'll have angst and fluff or just complete chaos. It'll also switch from human to skeleton, just a heads up there. Also the prompts are made up by me so..yeah. Anyway, hope y'all enjoy this!

Given An Unwanted Second Chance by UndertaleFanatic981

(TW: unaliving thoughts and memories at the beginning. It gets better over time, don't worry! Trauma is difficult to overcome...) You didn't want a second chance. You didn't want to survive. You wanted the sweet release of death. But it seemed like the universe was far too cruel to allow you even that. It took away your memories, your free will to choose whether you live or die...hell, it took the one thing in life you owned! Your own name! And now it seemed like you had to live yet another cruel life, doing things you never wanted done to others. But...at least you could do things your way. Maybe this second chance wouldn't be so bad... (Reincarnated as Nightmare Sans, but unlike other stories, you have no clue what Undertale even is) (WE REACHED NUMBER 1 IN THE UNDERTALE TAG YOOOOOOOO) (9/13/25)

a new art book filled with art I make of different fandoms along with fanart and art for my stories!!

This is a collection of short stories featuring the Blueberry version of Underswap Sans! Sanscest is allowed along with fluff, angst in some cases, and probably smut. Blue is only a bottom in this book, however, so please don't request any one-shots where he's a switch. Blueberry Sans is owned by the fandom as an alteration of Swap Sans.
