Outertale Stories

Frisk's spaceship crashed into an unknown planet, having only injuries and their determination they kept moving forward-ready for whatever this planet threw at them. This is an Outertale inspired AU, enjoy!! Taking December and January off to rewrite chapter 1-3!!

A sprawling collection of Sans x Male Reader and Papyrus x Male Reader one-shots, each exploring different universes, scenarios, and emotions. From lighthearted dates filled with laughter and teasing, to dark, intense encounters in twisted timelines, these stories dive deep into the bonds between you and the beloved skeleton brothers. Whether it's classic Undertale, an AU like Underfell or Swapfell, or even modern-day alternate worlds, each chapter brings a fresh take - romance, angst, action, or even a bit of smut, depending on where the story leads. No two stories are alike, but they all share one thing: you at the heart of it all, finding love and connection with Sans, Papyrus, or even both in unexpected ways. Perfect for fans of slow burns, wild adventures, and multiverse chaos, this anthology will make you laugh, cry, and maybe even blush. 💀✨ Your story. Your choices. Your skeletons.

What if someone from our world died knowing a lot from the undertale and their multiverse/underverse? What if that person also knew about the balance and didn't creat too many aus? Also they dont like creating sad au's like flowerfell or places they end up like dusttale or Horrortale. Yes they did make au's and may have not known what to call them so they took some names that they knew and remembered from the movie/game/their world like horrortale etc. But they also kept a better eye or eye sockets on his au's and their originals.

A story of a young Ink discovering what it means to be a Protector of Creation, as he finds his place in the Multiverse.

I was reborn as sans from my own made up au. How did that happen? I have no idea. Luckily I was still a kid so I didn't have to act like how I made sans to act like but maybe having that act on will be amusing? And wait how did I end up in undertale with my brother and dad and..other sans and papyrus? What exactly happened next? Well you'll just have to read my own story. (Also I made that up as far as I can tell. I don't think I've heard of an au called undersoul before so yeah..different things will happen and begin and possibilities of different personalities etc) different things and yes I made it up and it's not like it's real so I made up the stats for them etc.

The Descent Begins YN LN, twenty years old and quietly unraveling, lives in the shadow of Mt. Ebott. A jagged peak that looms above the city like a forgotten god. Their days bleed into each other, marked by faded photographs, silent rooms, and a growing weight of solitude. On the morning everything changes, YN wakes to dust and ache, haunted by loss and memories that no longer feel like theirs. A package from a kind neighbor, a forced smile, a job stripped away without warning, small cracks in a day that already felt too fragile. They didn't know they would climb Mt. Ebott. They didn't plan to leave everything behind. And they didn't know the mountain would open up beneath them, pulling them into something ancient, strange, and irreversible. Beneath the surface lies a world of forgotten magic, fractured souls, and impossible beings-each encounter stitched with mystery, danger, and strange familiarity. Who will YN become in a world that reflects them like a mirror cracked down the middle? Who waits for them in the Underground? And can anyone-human or otherwise-truly escape what they carry with them? A fall begins the story. But the climb back out... will reshape everything. Read on, and descend.

Fun little story after flirt/pacifist route. (sorta) NOT CANON

What if someone from our world became error and didn't destroy au's and left that for nightmare and his gang and claims au's? ( different things including personalities

This is the most random concept I've ever come up with, but okay. This is still going to be a school-based AU, set in college. Outer and Sans have been close friends since childhood and have known each other for a long time. One day, Outer starts noticing that the things he does with Sans might seem a bit too *gay* for his liking. After all, he's not gay, and he feels uncomfortable because, whenever others watch them, it seems like they see him as a gay person and assume he's dating Sans. Sans, who is just chill with anything, doesn't really understand why Outer suddenly started acting differently. Whenever Sans tries to hang out or casually hug him without any intent behind it, Outer avoids him. "Sans... I don't think we should hang out anymore. I mean, not permanently! I just think we should have some distance for a while." Soon this will escalate to many misunderstandings..

Outer Sans nicknamed Sirius has lost his friends and brother after his world glitches out of existence from some faulty codes. He develops severe depression which his friends across the multiverse help to subdue. He will have to cope with the loss of his brother and the new knowledge that he's now an out code, but not before reminiscing about all the good times he had with Papyrus and his friends.

Howdy, my friends. The whole story will be from the perspective of Sans as the reader, but there might be some P.O.V. changes. Enjoy the story =] A long time ago a war broke out between humans and monsters. After years of fighting, humans won and banished the monster into outer space, to a small galaxy surrounded by a bubble. Years after the war, the royal scientist and philosopher, Professor W. D. Gaster, created an experiment. The experiment seemed successful and he named it... Sans. Undertale is owned by Toby Fox, NOT ME!! I didn't come up with OuterTale either, this is just my take on it. None of the art is mine unless I specify.

[Official Rewrite of Wanderer, my Underverse Reader Insert Fic] You were bored out of your senseless mind. You didn't know any better than to get involved in a sick, twisted form of entertainment. You're just a stupid kid. You didn't know any better! Why would this be any different from before!? You just want to have a little fun, watching a new story unfold solely because you helped spark the inspiration of this tale. You stepped afoot into a simple story of pursuing a goal to help a friend. Too bad you're not very good at it. ஓ๑♡๑ஓ ❝ALL THE BROKEN PAGES THAT I LEFT BEHIND ARE THE BLOODY STAINS OF MY HOLLOWED PAST.❞ ஓ๑♡๑ஓ - can be found on quotev and AO3 - cover art from toilet bound hanako kun
