The humans sealed the monsters underground with a magic spell, after a long war many long ago and thats where they stayed until about a hundred years ago. The monsters had broken the barrier, and the humans were just beginning to get used to the new creatures roaming alongside them. This had caused havoc on your family, your parents hated you, and each other. It all troubled you, so you decided to end it. You stared at the hole leading to the underground, you closed your eyes and fell forward, but what happened next left you wondering, bewildered beyond compare. Now that you have the option to reset, your deciding if you should end everything, but you knew he'd remember. You knew it would phase him, but then you realize your not the only one with this power, and must stop them from misusing it. But will you be able to? Read to find out. (Cover created by me, story may contain a few slightly graphic scenes but anything erotic will not make its way into the storylines, minor tigger warning, suicidal theme IS inside this story, please continue reading, updates weekly, also READ THE PROLOGUE!!! It has background info that is relevant to the plot line)

Royaltale Season 1 by Uni_Is_Tenna

This is an Undertale AU I originally planned on making back in 2019 but, I wasn't capable of making all the character designs and forgot about it for two years. A few months ago, I thought about redrawing the only two designs and reviving it as well as changing most of the original plot and instead of making a comic series, I'm writing it so it will be easier to think about more designs. OCs are included in this AU. If you would like yours to make an appearance, message, or tag me to discuss when they can appear. This is season 1 of the series and it will basically follow the events of Undertale because there was a strange, unexpected reset after 10 years of living on the surface. Now, it's up to Frisk to help her friends remember their lives before the reset and save the world before Flowey tries to kill all of humanity as well as monsterkind and Mystickind. Can the determined human survive yet another perilous journey through the Underground or will everyone fall to Flowey's hands (leaves?)?

Hidden for so Long (Sans AU x Reader) {Discontinued} by RandomWriter-Chan

Please check out the remake of this story. Long ago the earth was ruled by two races, Humans and Monsters. One day war has broken between the two races. After a long battle, the humans...wait no the monsters were victorious. The monsters seal the humans into the underground using a magic spell. Humans were the one stuck inside the undergrounds but one human there was very special ,(Y/N) (L/N), like any other person she was a normal human she isn't perfect, makes mistakes, has her own personality. Her universe was different from all the other universes but the guardian of all of the AU's ,Ink, never really seen her universe before. Then one day while he was talking to Dream, Dream had found her AU then with several other Sans they went to explore her AU...

GJ!Underfell by GamagJ17

It's a personal take of, what if the monsters in the underground, instead of just being edgy, was trying to protect themselves from the extremely cruel humans of this universe?

Soul An Undertale Fan Fiction by karikitdemon

In the Undertale universe, a different human child falls down into the underground. Even though she is very young she will have to find her way home or stay there forever. ----- Big thanks to my friend from school who helped me out a bit.

A Strange Feeling (Sans X Reader) by Sak423

Do not expect consistent updates as life gets busy 🙃. This is rated mature because of strong language. You are a 24 year-old in college and have loved Undertale since the beginning. You enjoy all the aspects of the game; the story, the lore, the music, the backgrounds, and most importantly the characters. You've started having a strange, almost malicious feeling related to the Genocide run and that creeps you out. So, you start a pacifist run and after a while, you fall asleep. You wake up in Undertale and thus begin your new journey. Through your travels, the strange feeling comes back, but as a different emotion. Perhaps the only one that can help you with this feeling, is a certain punny skeleton. (I tried my best I'm not very good at summaries 🥲.) (Also I am so sorry for the kinda weird writing this is my first time writing a story. So I welcome constructive criticism.) Started: January 26, 2025 Ended: ???

The Animals Inside (HAITUS) by animal-sans

You are walking along a dark alleyway when you are ambushed and knocked out. In another universe, a young Sans is attacked and you both wake up in a white space with an offer being given by an elegant woman: take over the young Sans's body and let him live a peaceful life elsewhere. What is your answer? The story about my OC Look at my book about my AUs to get a better grasp of the backstories, what's happening, and the Sans and Papyrus MV nicks and CHECKs. All drawings used are my own, and I'm not the best at drawing human-like beings If there are references to other stories, they are coincidental, since this story is purely about my OC.

Undertale Observes Chara & Sans 《HAITUS》 by Sho0ting_st4rzz

What would happen if the underground saw what Sans and one other person do when they're alone? Read to find out. ------------------------------------------- Hi, this is my first story, please be nice. This is set in my own Multiverse that I created, so most of it isn't Canon. I hope you enjoy! ××××××××××××××× Edit: I'm rewriting/revamping this, and there will be major changes. Original story is up until New People, then there's the A/N's, and after that is the rewrite. If you want a ton of cringe, you can read the whole thing, but if not, just skip to after the A/N's

Undertale - Life Outside the Loop by Livathane

It's been seven years since Frisk set the monsters free from the underground, seven years since her choice to return to her human family. Magic is seeping up from the ground, slowly granting humans magic, spelling danger for humans and monsters alike. What's worse? A dark, murderous monster with terrifying power to possess is powering up through the genocide of alternate universes, bent on the destruction of humankind. (note: the cover is just a place holder until I figure out a proper cover. Secondary note. Current cover is purely because I feel like it. Third note. Aside from Plumetale. I don't own any of the AUs)
