Fellswap Stories

What if two brothers somehow end up in their own story as the sans and papyrus that they made? They called the story starfell, mostly because everyone in the story is like a tsundere, or something similar. They may act like they dont like each other and act like they hate each other but it's the complete opposite. What if after they finish learning how to use their magic, they end up in undertale with a lot of different sans and papyrus from different au's or universes. (Request which sans and papyrus you want in the story, I got a few in mind, but I want some more to put in the story before this sans and papyrus is there. Personality might be different, things will be different, I'm probably going to be horrible at making this. I got this idea from a few people from ao3, they made a stories with becoming a sans and papyrus or just a papyrus by themselves or something like that. I don't remember their user name, I remember one of the names to one of the stories that was made, it's called Vindictive care ao3 I believe, you should go check it out, it's awesome) Also to warn you that I also made up the stats on spot, it's not supposed to be realistic but made up kind of thing so don't complain about the stats or something and Also to warn you I'm not good with puns since I never made one so don't expect them to be good or anything You can also request a chapter on what you would like to see or read next (Au name of planet and star- starfell

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.

FELLSWAP SANS X UNDERFELL SANS .................. okay seriously, help. .... quick summary here: Fell is abandoned and is found *coughs* captured *coughs* by Razz ... lol

Under the training of Dr. Strange, (Y/N) is learning to control her powers. But when she i left alone for the first time. Skeletons suddenly start appearing out of nowhere. Can she figure out what is happening?

This is about the Alternate Universes of Undertale, about a new monster. A Human-Monster Hybrid, she was an experiment of W.D Gaster. Gaster wanted to see if it was possible to make a new soul, so he took a bunch of humans from the surface without the assistance of a human soul. The girl that the experiment worked on her name was Violet but Gaster gave her a subject experimental name, it was VB21T this stood for VioletBex21True which meant it worked. While all this was going on Gaster told all this to Grillby, who was his former best friend before he disappeared he told him to tell one of his sons this information about Violet as he said it would be helpful in the future...

Family. No family is perfect, flaws are a part of every one of them. No families are the same, some have no love, while others are filled with it. Most families are... Complicated; "You aren't getting them back Nightmare! We won't let you hurt them anymore!" "Damn it Dream, give us Y/n back! You know nothing about them or how they were treated here!" ________________________________________________________________________________ Some families aren't related by blood, and that's okay, they don't have to be; "Nightmare, we don't say this, but you make us a family." The most important thing about a Family is Love. Love can come from anywhere, but in this case, it comes from Y/n, a beautiful dog taken in by a few strange owners; "Nightmare! Horror lost Y/n!" ________________________________________________________________________________ None of the art is mine. Will be trigger warnings. You, the reader, are a dog. They/Them. Fell is genderfluid in this.

A short story about an encounter with Error sans

This is a rewrite of my first ever Sans x reader kind of story. I hated the first one for bad writing skills, but I have come a long way from that. So have fun. *Hi, I'm (Y/N)! I lived a mostly normal life when things started going downhill. And I don't mean the diffrent kind of skeletons kidnapping me. But oh well that happened too. Come find out about my horrible borning life turning into a horrible nightmare. Or even perhaps something romantic..?*

Hi guys! First of all I should mention that the story pic isn't mine and of course Fellswap belongs to its original creator. A young hiker, Y/N gets lost and accidentally falls into a pit while stumbling in the dark. She wakes up to find herself in a whole new world that was never spoken of before except in children's stories. That's when she stumbles upon Barb (aka Mutt) and makes her first friend in the underground! But other monsters that live here aren't so welcoming.

just some headcanons/ideas of how I think the different AU sanses and papyruses would act in a romantic situation :>

Random UnderTale crap from Utauloid/Vocaloid talkloids that I use different UnderTale characters for the talkloids and UT Comics

TYSM FOR READING! THIS WAS THE FIRST BOOK/STORY I MADE! I hope some are inspired by it. I just finished editing it (July 19th, 2023, 5:37) PLEASE LEAVE SUGGESTIONS FOR AUS!

The title says it all. Right?

Undertale Sans... Underswap Papyrus... Storyshift Chara... What could go wrong?

ᴀsᴋ ᴍᴇ ɪғ ʏᴏᴜ ᴅᴀʀᴇ =)

(Y/n) finds herself in a bit of pickle when Ink Sans explains to her about the condition of the Sanses of the multiverse. No matter what, she is determined to help Ink Sans and Error Sans to find a solution, and protect the others from the hacker. Although, it turns out to be a bit more difficult than she thinks. The multiverse Sanses had been turned to kids, and together, they are impossible to tame. How will the trio manage the kids? Will Ink and Error ever tell her their feelings? How will Core Frisk react? How will turn everything back to normal? How will they fight Nightmare Sans? Will they win? Or will the multiverse be forever consumed with despair and misery? Let's follow (y/n) on her journey and see what happens next. I do not own the multiverse or any of its characters, I don't own you either. I do not own Undertale. I only own the added characters like Hacker and P.

When Johanna is stuck in FellSwap, with no way to get back to her own AU, what will happen when she notices Raspberry Sans flirting with her?

You've heard about Frisk Dreemurr, Ambassador of Monsters, savoir of the Underground, but what you don't know is that he has a twin sister. Y/N Dreemurr, she's Frisk's twin, though she never traveled to the Underground with him the Dreemurr family accepted Frisk's twin with open arms. That was 10 years ago, now at the age of 21 Y/N runs her own little flower shop bookstore hybrid business. Sans Serif, a brilliant skeleton monster who hides behind a smile and laziness. Older brother to the Great Papyrus. He and his brother are also the Soulmates of Frisk's twin sister Y/N. He messes around with something he should've left alone and brings more versions of him and his brother, along with another version of the late human child of the Dreemurr family. Turns out that they're also Y/N's Soulmates. Chaos and hilarity ensues as they fight for the girl's heart and love.
