Undertale Stories

Reborn as the guardian of positivity, you find yourself in a strange new world, uncertain of what it may hold. Navigating it isn't easy with gods like Nightmare and Error trying to strike you down every step of the way. But unlike the previous Dream, you have nothing to lose, and are determined to forge a better path than the soul whom you have replaced.

"the healer likes t' sleep. like, a lot." Axe looks at the sole female AND human member of Nightmare's subordinates. She was only ever awake for about 8-10 hours a day, rarely ever 12, it was both fascinating and irritating at the same time. He was damn sure humans would be awake for more hours than that, he even asked Murder at the time if it was normal. Said skeleton didn't give a single care though, his words: "who cares, makes her more tolerable. 'sides she gets her job done." The cracked skeleton just couldn't shake off the feeling that there was more to it than meets the EYE. ━━━PHOTO CREDITS: Whale鯨豚 [@Whale5511] on X! ━━━MOST NOTABLE RANKING: #1 in sansxreader, horrortale, something new and badsanses on 23/12/2025 #1 in undertale on 25/12/2025 #3 in bittersweet on 24/12/2025 #5 in reader on 24/12/2025 #19 in sans on 23/12/2025 ━━━━━━━━━━━━━━━━━━ DATES PUBLISHED: 001 ━━ July 29th of '25 002 ━━ July 30th of '25 003 ━━ August 1 of '25 004 ━━ August 3 of '25 005 ━━ August 6 of '25 006 ━━ August 8 of '25 007 ━━ November 8 of '25 008 ━━ December 22 of '25 009 ━━ December 23 of '25

This Au start with a skeleton who has a special hidden magic that no other monsters in his Au have ever seen he named himself as "Sans" but in other sanses from the different Au calls him "Wisteria" Wisteria is the only monster that has special hidden magic but his plant manipulation is very special to him on his Au all monsters in WisteriaTale can create and grow different kinds of plants but, Sans is different instead of creating different kinds of plants he can only grow 1 different kind of plant which is a "Wisteria Tree" that glows brightly when there is no light.

Why Toriel, with her creepy obsession with the fallen children and in need of Therapy. Was it truck-kun? They'd rather like to know, and really hoping this is cannon and no Genocidal children At least its after the run to the ruins portion they took over Co-written with Philippaki!

I have too many memes so here

Where did this goat monster child come from? Who is this child?! So many questions that never seem to end and only grow when one in answered. It is safe enough to assume that the multiverse might might not be the same after meeting this odd little goat child and some learn that some questions are better left unanswered. ~~~~~~ OC goat monster child who has a mysterious past and causes waves with every step they take.

A small crossover between undertale and kirby. how will this adventure go? let's find out No videos or sounds are mine No characters are mine

Corporal Adrian Shephard, a US Marine Corps soldier assigned to the HECU division, was sent off to Black Mesa for 'cleanup duty'. Despite the hell he went through, the marine somehow manages to escape the dangerous, alien-ridden facility against all odds and, after being 'detained' by the ever elusive G-Man, is then assigned a new mission many years later... to the UNDERGROUND! Accompanied by Chara Dreemurr, the first fallen human turned apparition, the two journey through the unprecedentedly large Underground for one, very specific goal... but what exactly was it? And is that all there is to it? In... time, all will be revealed.

You are reborn as errors..... But you are crazy teenagers who will pretty much make a lot of mistakes. You mess around with the star and even the bad sans. You call yourself a alone wolf, but you end up getting brother's some how in the end that will raise you how to act right and responsible for your role. Whichs suck because you want to have fun. And fate is mean, but she finally found an error sans that will do its job without complaining, but he or she is annoying, and like costing her trouble! But she can't help but to be an aunt for newborn error. How did you become errors sans? Well, you were playing undertale, and you oh ways like to do genocidal all the time. But you wonder what was sans view of your wrong doing. So you stopped doing genocidal feelings, and it was wrong later. Unilt you joke being errors sans bit And magical die from saying that. But you're not only one who calls Error sans some of your brother too

Have you ever thought about what it would be like to be.. Sans? Be Papyrus' lazy and playful brother? Be a comedian with endless jokes? Be the mysterious judge? Be well-liked? You envy him. You wanted to be him. Yet nothing could've prepared you for what's coming. . . . (WARNING, THIS IS A MIX OF CANON AND FANON FACTS. THERE MIGHT BE THINGS YOU DONT LIKE BUT JUST BE THE BIGGER PERSON AND TOLERATE IT. THIS IS NOT MEANT TO BE TAKEN TOO SERIOUSLY AND IS INTENDED ONLY FOR ENTERTAINMENT.) (Cover made by me. As you can see, I made that thing on IbisPaint. I understood nothing about making book covers and I messed up on the proportion many times so I gave up and that's how the cover came to be. Idk how to shade and make backgrounds/landscapes btw) (Tbh I wished I made this far earlier because it's late 2025, no one is going to read this pile of nonsense. 😭) YOU GUYS HAVE AN OPTION TO CHOOSE THE DIRECTION OF THIS STORY THROUGH FREQUENT POLLS I MADE!!! First thought of and made on 1st Dec 2025 Posted on 6nd Dec 2025 cuz I was feeling confident for that hour.

Clover doesn't give up his soul because justice still needs to be delivered. The Wild East, and later practically the entire Dunes, declares independence. They declare that any human within their borders is under their protection. Civil War looms over the Underground. Would you like to see what happens? Note: This is NOT a story. This is an archive containing information about my AU, Desert Sanctuary. I might write a proper story in the future, but for now, this is where you can read about the narrative, the characters and how this massive change affects Frisk's journey. Fanart and other fan works based on Desert Sanctuary are welcome and encouraged

nightmare and his gangs sadly die but nightmare was telport to another aus called Naj but pregnant with the gang. we're talking about giving birth to horror, dust, killer, cross and error 💀 poor nightmare he going to be in lot of pain. He get luck if another soul doesn't come.

TW: Swearing and slight gore Y/N reincarnates in the anti-void as a Voice... Will he befriend error or will they make them hate their guts? And will they meet other people? Only time will tell. Hello, this is going to be my first book and idk if it's going to be good so meh :v This story was inspired by transported as a voice by Virus_bOi, I obviously do not own undertale and I don't keep up that much with the fandom, so some personalities might be different, but hey. I can just say that it's a different multiverse ¦ ] The cover image is from Shira Wolfiecute on tumblr

Abandoned on Mt. Ebott at the tender age of five, young Harry's unsurprisingly died, but Death's always had a weird relationship with his variant... Meanwhile, before Flowey's revival as souless talking flower, Sans makes a discovery under the mound of snow, Papyrus has always wanted to be a big brother anyways. *Edited Summary (29/09/2025)

(This is my second attempt at a remake So please enjoy this as I'm going to put much more description than the original) All characters involved are mostly out of character from their original counterparts. {This remake will bring new episodes, remade episodes, episode changes, spelling corrections, lots of editing, more pictures, more videos and new personalities from characters} (There Will also be more crossovers than before along with mentions of some of the My Little Pony creepypastas) Can even the most broken person be put back together. In This Au of MLP we will find out for ourselves. Y/n: I can't believe I did all of this to the underground.... Is it possible for me to truly change? Dusttale x My little pony friendship is magic WD GASTER: Things will be very different, this is for you to find out dear reader. This au is a very twisted version of the original My Little pony show. None of the pictures are mine all credit goes to their respective creators MLP:FIM is made by Hasbro.

(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)

Exploring the underground after Flowey was given The Justice Soul by Clover-the 7th human.
