angst betrayal chara death disbeliefpapyrus family feels frisk-kinda geno genocide imbadattags otherfunstuff papyrus sans sorrynotsorry theories undertale wdgaster

A human fell into the Underground, and began befriending every monster they came across, including the skeleton brothers. Their acts of kindness seemed to be genuine, giving the monsters no reason to distrust them... Until the human pulled a one-eighty and killed Sans when everyone least expected it.

This is the story of how Papyrus grieved over his older brother's death, how he discovered the truth about his mysterious sibling... and eventually, how he decides to avenge his sibling's murder.

But in the end he'll forget everything once the timeline resets again, right? That's what he's afraid of. 

(Based on the AU "Disbelief Papyrus," but with an original twist. There are no pairings except for what's canon. This is mainly Papyrus-centric, but it does focus on mystery of Sans during the story.)All Rights Reserved

My Fault - Underfell Fanfiction (Sequel to Your Fault) by DragonzRawesomE

{COMPLETED} It has been just two weeks since the event that changed Papyrus' life forever. Too late, it seems, he realized what he had. And now that it is gone, he has fallen to pieces. How, or if, he will be able to cope, he truly does not know. And as if that wasn't enough, there are countless mysteries in store for this burdened skeleton-- coming from people he thought he could trust, and in places he thought that he knew. Will Papyrus ever be able to solve the mystery behind this devastating chain of events? Or will he, too, fall prey to the ever-expanding void that is engulfing the souls of himself and everyone around him? PLEASE NOTE: This book is the second in its series. It contains major spoilers to the first book, as well as this book may not make much sense without having read it first. So, if you want to keep the excitement of the first book without any major spoilers, I HIGHLY suggest going and reading that first. It is titled Your Fault.

A Skeleton's Hope (Undertale AU's x Reader) DISCONTINUED/BEING REWRITTEN by Just_Vibing_Man

Sans and Papyrus were your best friends until randomly they just cut off all contact with you. This went for everyone else in your life so it didn't really hurt that much when they did. The only question is why they didn't do it sooner. So after two years of loneliness, what was originally a drop off turned into a hospital trip, a broken leg, and your once best friends now homeless. What should be happening is them owing you a thanks for rescuing their so called, "Cousins" from a fire. Yet here you are offering them a place to stay, at your big ass mansion for the next eight months. So now you live with the people who abandoned you, along with their so called "family" who by the way don't really like you because you're a mage, but it's barely relevant to the plot so - What could possibly go wrong?

Bloodfall (An Undertale AU) by BlackStormWolf

Ever since the death of his younger brother. Things have gone downhill in the surface world for Sans. Alphys died a few months after Papyrus to a disease, Mettaton and Undyne, especially Undyne, had fallen into a depression. Flowey dissapeared into mt. Ebott, not to be found and Sans is fighting depression and insanity. One day, Sans discovers a suspect to his brother's death. A being that is trapping anyone who had either fallen into Mt. Ebott or stayed behind in snowdin for a while. Sans, along with Frisk and Undyne, go into the underground themselves to confront this being. They must encounter the Bloodfall that traps and kills anyone who dares pass by waterfall. (This takes place after a true pacifist run if one killed Sans in a Genocide run, but reset their game before getting to Asgore(I did this in a way to quit the Genocide route). This is if Frisk choses to do this the Pacifist way. I might make a Genocide one in Story Shorts. Also, My Sans is a human, but feel free to interprate him as a Skeleton if you ever choose to use this AU. Just credit me!)

Remembrance - An Undertale Story-DISCONTNUED by MEJ2235

Long ago, two races ruled over the Earth. Humans and monsters. At least, that's the story we all know. There was another race. Technically, they were monsters. Skeleton monsters to be exact. Humans shunned them because they were monsters. Monsters shunned them because humans had skeletons. In retaliation, the skeletons split into two different races. The Surface Skeletons and the Abyss Skeletons. The Surface Skeletons reaches out to both monsters and humans. However, when the war started, they were some of the first monsters attacked and many were killed when they fought with the other monsters. Only a handful were sealed underground but without the Sun to strengthen their bones, the skeletons suffered until they received anonymous help. Very few survived to this point and slowly, they died out. The Royal Scientist at the time and his wife tried to have children. Each time left them severely weakened. Each child dusted until the wife gave up her life to bring a great skeleton into the world. That child is the last of his kind. The Abyss Skeletons shunned all other monsters and humans, considered them all demons. Their society was alike human society long ago. Divided. They believe they are strong and emotions only weaken. The class system was rigid and they possessed a kill or be killed attitude to all other monsters and humans. They thrived underground and ended up building their society in the Underground's own Abyss. It is a shame that only their leader can reclaim their heir from the corruption caused by those demons. Warning: Rated Mature for possible smut and probable gore. I'm sorry I don't know what I'm doing but this ain't for little kids. Also, cover doesn't belong to me. Credit to creator. Found it randomly when I searched up Undertale.

(Sans x Reader) When Two Souls Meet by ZanaBSparrows

Sans has lived through countless timelines. He's seen the kid make friends with everyone, only to give up in the final moments. He's seen the kid killed, over and over and over again. Sometimes, he'd even done the killing himself. And no one ever remembers. Not even the kid herself. It's an exhausting cycle, one that never seems to end. But there's something different about this run. Another human's fallen down... the kid's sister. Please note the the story is primarily on Quotev, so updates to Wattpad may be late, or lag behind that of Quotev. The story also has the potential to become mature. (I haven't decided yet.)

Conduit Tale-An Undertale Fanfiction Novel by Serena_Walken

(Complete)Hopeless and in despair, Sans never thought he could escape the resets and continues caused by FRISK that tormented his life. But, when he thinks the kid is possessed and stops FRISK once and for all he finds out ... that he never really knew anything after all. No more resets. No more saves. No more hiding. Life will never be the same for the Underground. Souls and Science can be an unforgiving bitch. Relationship: Because of the nature of the way this fanfiction works, there are several Frisks. He knows all of them, but Sans only falls for one, and she is definitely over the age of 18. This doesn't blossom until some time later though, as this is way more than a sweet romance. Buckle up for some tragic dramatic scifi-twisting to the fantasy world of Undertale!

PATCHWORK SOUL by SparkTheBarkivist

[Complete] When Frisk finished her story, barrier broken and monsters freed, she knew there was still a loose end, but she never expected everything to come unraveled before her eyes. Determined to save the only family she's ever known, Frisk must stitch their lives back together after they are ripped apart at the seams and then attempt the impossible to stop it from ever happening again. [A story like this has been told before, in many different ways by many different people. Even so, I hope you enjoy it. Please know all major canon timelines and the music of Undertale before reading for the best experience.] [An AU of what happens after a specific time kid's True Pacifist ending.]

What Went Wrong? by AngelOfTheDead80

~'Disclaimer: This story has a lot of profanity and covers some very very intense or touchy subjects that may disturb some readers. You have been warned.'~ ((Unedited)) After Chara fell into the Underground, they met Asriel a monster inhabitant of the Underground. Soon after that, Chara joins a new family, but their ambition to keep everyone happy goes a little overboard and Chara is flung into a reality of destruction and hopeless wonder. Then many long years later they meet the beloved Frisk, who fell into the Underground, similar to themselves. Eventually everything Chara thought they knew correctly is turned upside down and they as a person are changed forever. ~'The game Undertale belongs to Toby Fox and some of the dialogue is ripped straight from the game itself, too.'~
