Undertale Stories

(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)

If given the chance, would you start over? After falling into a timeline where nobody was murdered, his mother never died, and his father was never erased, Sans should be ecstatic that he has a second chance with his loved ones. But there is no denying the trauma he'd been through, either. Everyone is supposed to be dead, after all. What if Frisk comes back to take it all away again?

Y/N wakes up in a void and goes around the multiverse (Also these powers aren't mine, but I wanted to use them and put my own spin on it, if you know where they're from then good on you, your cool in my book)

I have too many memes so here

After falling in battle against Chara and losing everyone in the Underground, Sans awakens in Mewni, a strange world ruled by ancient magic and wild creatures. For three weeks he survives alone in a cave as a hermit until witnessing an important event: the birth of the kingdom of Mewni, where Glossarick grants the first magic wand to the settlers, beginning the history of the kingdom

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

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. I can proudly say I've been doing this book since last year hahhahahahahahaha (get it cuz I did this thing is Dec 2025 and now is Jan 2026?) I made the cover btw

You are an orphan that was being chased by a dozen Orphanage keepers. You had just witnessed your friend's death and had ran away. You quickly run to Mount Ebbot. And you jump of a cliff into Mountain. You hit the ground and black out. When you wake, you are greeted by a family of monsters and 2 humans. They become your new family. All is well. ... Right?

It's mostly about one-shots or ideas about Undertale (and AUs too, of course). If you like to use my ideas or continue a oneshot, please credit me and message me! I'd like to read it :3 Cover is mine!! Don't steal!! #2 on ideas - January 25, 2024 (how the fu-)

The genocide route ended in a bright hallway. Sans lost... And something followed the reset. Itsuka Shidou begins to experience dreams that aren't his, instincts he never learned, and reactions no human should possess. As Spirits descend and spacequakes tear his world apart, an unseen presence watches from inside his mind-silent, tired, and all too familiar with death. This time, there are no resets. Judgment comes after zero.

reader with sans power and attitude being izukus brother in mha.

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)

What is Ink was reborn? This is a fan fiction both inspired by the story "reincarnated Error" on Wattpad and "If Blue joined the bad sanses" on YouTube. The reincarnation part was inspired by Reincarnated Error, but the version of Ink I will be using and the backstory I'm going off of is from the story if blue joins the bad sanses. I am not at all a good writer and my autocorrect does shit without my consent so sorry if this sucks, I greatly appreciate if you correct me on some things. (no art is mine unless said otherwise. The cover is mine though.)

Cover image made by me. Someone meets their end too soon and meets someone who gives them another chance to live a more fulfilling life. One that they would enjoy despite the problems that may come along. In other words, reader becomes Error.

This isn't a normal Y/N story the bad sanses do a raid on an illegal auction of many rare, dangerous, and illegal things. but after the dust settles, killer finds what he believes to be a weird mutated cat and decides to take it back with him art by me. my first book, and feel free to correct my spelling in the comments Y/n means your name Y/fc means your favourite colour Y/fm means your favourite type of meat Y/hl means hair length Y/hc means hair colour Y/sc means skin colour Y/ec means you're eye colour

"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

Undertale, Classics AU, meets alternate versions of Sans, but things take a turn between scercts and trust between them.
