alphys asgoredreemurr asrieldreemurr fanfic flowey gaster mettaton napstablook papyrus sans temmie torieldreemurr undertale undyne

‼️English isn't my first language.‼️
Also most of these are not supposed to make sense. I tried to make them sound as logical as possible though

I used the super edgy Undertale theory generator, the hardcore undertale theory generator and the undertale fanfiction generator to make some short stories!! :D
This is just something I came up with for fun so, hope you enjoy reading it! ^^

Undertale - Put Things To An End [Frans] [Book 2] by SepticGirl88

This is a story that I originally wrote quite awhile ago on Deviantart. So please excuse the cringe if the writing is really bad.

What Lies Inside (Gaster!Sans x Reader ) by Jaethefallenhuman

"You know sweetheart, lying doesn't get you anywhere with me." He said lighting a cigarette and placing it in between his teeth. Vanilla, leather, and smoke is quite the intoxicating smell. "I'm not lying, also who gives you the right to judge if I'm lying or not?" Something flickers inside me, a warm burning feeling that fuels my anger with this asshole. Walking up closer to me he pins me against the wall, smoke dances around his skull in a vary of swirls and curves. "Let's get something straight dove, I am your worst nightmare and I am your best daydream. I can see right through people, ironic right? There's something about you, I know you're hiding something inside." He really is good at seeing through people, but the thing is I'm not like anybody else. The media I use in this book does not belong to me, they belong to their rightful owners! Gastersans is NOT my original character ! He was created by Borurou Undertale was created by Toby Fox Highest rankings #1 Gatersansxreader #1 Gastertale #19 Gastersans

Sacrifices (Undertale FanFic) [COMPLETED] by Brynwyth

Frisk has freed the monsters of the Underground. Finally, monster kind is allowed to return to the surface. It's been 3 years since then. Yet the monsters still struggle to find their place within the world. Most accept the monsters, but there are those who wish nothing more than the complete annihilation of monster kind. Merely sealing them away is not enough. As ambassador for the monsters, it is Frisk's responsibility to fight for everyone's right to live on the surface. But at the same time, an internal battle rages on within her. Not only that, her relationship with Sans is strained. Trust is not so easily regained after the slaughter of one's beloved, despite it all being erased. Or was it really? The memories are still there. *I have lost interest to complete pre story and post story parts. Please enjoy the main story and the extra tidbits.* Chinese Version: http://fav.me/db7h2kg DISCLAIMER: I do not own Undertale. TobyFox is the creator and owner. Cover art does not belong to me.

Sans Can Never Forget | Sans Angst by Minksxy

Your favorite skeleton is back at it again... and again... agagaagaag Sans has had enough. Everyone is at the surface, holding their own jobs and lives. But... Sans can't ever let it fade from his mind. The dust. The cries. Watching the screen with Alphys as a child just rampaged in the underground. He is going to snap. He is mad. He is sad. He can never forget. Cover is NOT mine, find it online if you want ::Rights for the original concept and media 'Undertale' are all under the jurisdiction of Toby Fox. All other workings are done by me.::

Undertale:Secrets by ItIsComic

Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great. Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 24th May 2021 Finished: 29th December 2021 A full 7 months of great fun with this book!
