As the title states, these are random oneshots involving Sans and his AUs. Feel free to read at your will. There's no regular update schedule for this since I may get lazy at some points. Also, I am a big multishipper who likes making my favourite characters be the submissive ones no matter how powerful they may be.

Warning: There will be stories that contain or mention topics such as depression, suicide, death, insanity, etc.

None of the art is mine. They all belong to their respective owners. Also, all of the Sans in this aren't mine and belong to their creators.All Rights Reserved

A Mistake's Beginning [Moved to AO3] by livinganime14

- • x BLOOD AND GORE WARNING x • - Error stops, Where is everyone? It's so empty here... walking through the ruin halls he found nothing. no one, not even a whimsun. Perhaps this is a Dusttale AU, it must be! Error thought as he finds himself in Toriel's basement, there was nothing, not even dust or corruption. walking out into what is now Snowdin town.. wait, that fast already? That was new. A snap and rush. why is everything so different now? ----- A rush of panic waves through Nightmare's brother, how unusual. Nightmare takes the gang to this AU, knowing Error is here. he looks around looking for the said emotions, not feeling any in the area was wrong. No one was here. a rush of panic, fear and guilt calls to him and he runs towards it. WHAT THE HELL IS HAPPENING?! ----- Credited to Harrish6, who's account is found on ao3, FanFiction. Net, And Wattpad. I do not know if they are on quotev, but I've found them on those platforms. They're still continuing their stories, and everyone credits them for the inspiration of creating the forced god part of the undertale fandom. I've ranked 1 in #fgoderror #sans and #Harrish6 I've ranked 10 in #undertale A big achievement on me! I'm so proud of myself and thank you for everyone reading this book and getting this here. (I don't remember the dates T-T but I published this fanfic at the start of September so it was around September-October of 2020.)

The Boy Who Doesn't Speak (Sans AUs) -- BEING REWRITTEN by SKSuperKitty

For some reason, Ink, the Creator and Protector of the Sans AUs, has decided that some of the Sanses of the Multiverse should go to highschool again. Honestly, no one really liked the idea, especially the Bad Sanses, including Ink's enemy, Error. Prince Nightmare is one of the AUs that must repeat these years of treachery. He basically only finished his actual highschool, and is NOT looking forward to having to do it again. Luckily his brother, Prince Dream, will be coming along the journey beside him. But Nightmare and Dream Are polar opposites, so Nightmare can't really get along with his brother's friends, nor Dream get along with Nightmare's, if he had any. With rules to follow and secrets to keep, Nightmare must go through highschool and not let slip the terrible things that happen at home. But then suddenly the two princes disappear. There's no trace as to who might've taken them, either. The only one that doesn't seem concerned is their own father, the king. King Sun-Beam. What is he hiding underneath all of those jewels and fake smiles? A/N: There is lemon/smut. So all you innocent people out there-- don't worry! Because I warn you at every chapter, and right before it happens. I designed the cover, but did the not the amazing artwork of Nightmare Sans. So credit goes to that person for the art. :D Update!!!!: This story is being rewitten. I'm making another book that'll just be this one but a little different. Once that's posted, I'll make another "chapter" in this one, giving a link to the rewrite. Thank you to everyone who still reads or checks up on this book. <3333

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!

Capture & befriend (one-shot sanscent) by moonsanslovesjam

Mostly about Moonsky sans by https://x.com/moonsans123 and the bad sanses, and ships so :/ This story will contain alcohol, smoking, drug use, swaring, abuse, misspelled grammar and, violence, very detailed descriptions, kidnapping, LBTQR, Lemon, lime, fluff, angst, masking autism, panic attacks, mental illnesses, self-harm, PTSD, experimentation, and very uncafterble topics, TW Rape, and thoughts of suicide, and ships you may feel uncafterble with. If you are uncomfortable with this, then I would recommend not continuing with this book. If you want to leave a request, you can. I will try my best to write as much as possible, and my stories will most likely be split into two parts.

Justice (Ink!Sans x Reader) [COMPLETED] by the_pacifist

Heya! This book will be a bit of a slow burn, which means that all the ~romance stuff~ won't happen until a little later in the story. ~~~ Twenty year old (Y/N) has sworn her undying loyalty to none other than Nightmare, one of the most feared villains in the multiverse. She's been working with him for years, since she was seventeen, but she's never encountered the infamous Star Sanses. She wishes that she could meet them, she hopes that she'll be able to fight them some day and end their existence. Her ultimate goal is to impress her boss and to prove herself to everyone who told her that she wasn't good enough. Will her wish change when she encounters the Star Sanses? Completed 12/24/2021 ~~~ Pronouns used in this story are she/her Disclaimer: None of the art used belongs to me! If you see your art/know the person who made it, feel free to let me know so I can credit them :) *Cover art belongs to RyuuseiRissu on DeviantArt*

"Bullseye" A Killermare story by Tornado346

Killer is a sans, and so is the rest of his crew. They call themselves "The Bad Sanses." They've all had one goal at some point in time, revenge. However, Killer is a unique specimen. He is an emotionless being. He feels nothing and nothing only. No remorse. No happiness. No mercy. All he knows is "kill," and that's how it's been for long time. However, one day he comes across a new particular type of Sans. A very colorful one. He feels something he hasn't felt for years. Freedom. Once Nightmare finds out, it's not pretty. Killer was his most loyal worker. So he decided he had to end this "friendship." The question Killer asks is, why? "Why do you need me to feel nothing? Why do you want me to be a part of your crew? You always tell me how useless I am. If I'm so useless, why do you need me?" Nightmare couldn't give him an answer. But, maybe, for once in his life, Nightmare feels something for only Killer that isn't so negative. 🎨COVER ART🎨 COVER ART WAS NOT CREATED BY ME, I REPEAT, NOT CREATED BY ME ART WAS CREATED BY pecil(BB) or @mm_loves_pencil ON TWITTER SUPER FREAKING TALENTED CHECK IT OUT!!!! ⚠️Warning⚠️ This fanfic is a little toxic. I tried making everything as possible, which is why I'm putting this warning. However, after writing this entire story, I realize some things are more fanon than canon. Nonetheless, serious angst goes down in the fanfic, so be warned. Contains: Heavy language Sensitive topics (such as abuse, trauma, and depression) Angst Smut (maybe, I'm still deciding) Graphic scenes containing gore -if any of the following bother you, I highly suggest not reading this fanfic- |you have been warned, so don't come at me if you don't like it| I promise it all ends on a good note. I can't personally stand depressing endings. So don't worry. But hey, enjoy your overdose on Killermare. 🤷♀️
