Don't ask where I got the idea... I just learned about Error Sans and I've always loved Aftertale Sans. I instantly fall in love with every Undertale AU, even UnderFell. Most art of it is just creepy. I'll do more Sans au ships if wanted. For example;
Sans x Underfell Sans
Swaptale Sans x Sans
Error Sans x Underfell Sans
Error Sans x Swaptale Sans
Sans x Aftertale Sans
Gaster Sans x Sans
Aftertale Sans x Underfell Sans
Gaster Sans x Underfell Sans
Gaster Sans x Error Sans

His Summoner || Demon! Nightmare Sans x Reader by StrawberryMilkSnake
74 parts Complete Mature
When a demon summoning goes wrong, a rich and powerful man's son gets killed and (Y/n) is forced to team up with the Demon King that did it to survive the ensuing attempts on her and her family's lives. But the King will only do it on one condition: he gets her soul. So with no choice but to die for her mistake, His Summoner promises him her soul when the job is done. | - Demon! Nightmare Sans x Female Reader - A little bit of a reverse harem with plenty of Bad Sanses x Reader moments (with a canon reason for it :D), but ultimately, (Y/n) is Nightmare's - Honestly you could read this with no prior knowledge of any of the characters and you'd be just fine - Kinda a slow burn? But don't worry, I throw in so many subtle/not-so-subtle intimate moments with all the Sanses that it makes it worth the wait :D - I'll throw in some bonus chapters with the other Sanses for extra (non-canon) fluff that doubles as a breather from the story, too - Is the relationship toxic? Maybe. I mean, this is canon Nightmare after all. But that's the beauty of a fictional story, no? - A lot of the symbolism and hidden meanings aren't obvious, so you might have to be on the lookout to see them (and keep in mind: Night doesn't openly show many emotions, so the devil is in the details) - I'm not going to spoil anything, but for all you anxious readers out there like me, I'll divulge I'm a sucker for happy endings *wink* - It's my interpretation of the characters (kept as canon as possible)
The Bone Warrior (Sans x Female Warrior Skeleton) by Lunargal624
16 parts Ongoing
Your name is (y/n) and you have lived on the surface as a royal guard for the science department in the monster areas. Your species is skeleton, there's still a good amount left of the skeleton race but then the monster side of town broke into chaos and war. You were manning your post when you see humans running after innocent monster childeren and their families. You instantly run towards the humans and start attacking them but you quickly get overwhelmed by all of them and the gunshots that you've just barely managed to dodge. You start running to buildings to get out innocent lives from the fires that are now spreading through the town. Your actions lead to hundreds if not thousands of lives saved that night. You were one of the last ones out with the other guards just in front of you. With your magic you manage to hold off humans attacks from the monsters that are heading to the underground that is supposed to be a safe haven if this was to occur. That's when you get hit by a rock in the back of the skull. This book is about a long lost skeleton warrior in the game known as undertale. (Not cannon of course) I'll be using (y/n) as her name so you can choose it to be your own name or a chosen name. All rights are reserved as far as the images I've used and of course undertale the game itself. If I do mess up on something, do not hesitate to tell me. I am all about constructive criticism. Lastly, there is a no hate policy. If you are one of those assholes who thinks it's a great idea to say you people are sick for reading this then why are you even searching things like this in the first place? Lastly, there may be some adult writings in this book, if you are innocent, stay innocent but if your not or your willing to give up your innocence then come on in and join the party. Anyway, if you did read all of this, thank you a lot. It really means something to me.
