brothers fanfiction flowey possession sans sansxfrisk skeletons undertale

Frisk is happy that she's with all her friends she made in the underground. But something's up. Flowey had ran away when Frisk had defeated him. They think he wants revenge, but they're not for sure. Then things start going on with Sans. What's going on? Can they find out what's going on? Just read to find out! I write ideas that come to my head! :)

Btw, my later writing/chapters are so much better than what it was at the beginning chapters. XD
And also, I didn't know so much about Undertale at the beginning of this book as I do now. XDAll Rights Reserved

Thanks to your knowledge as a doctor (and oath to do no harm), you're able to convince the Great and Terrible Papyrus to keep you alive. But how are you going to find your way back to the surface with a bum leg and a short skeleton that doesn't seem to like you? | - UnderFell Sans x Human Reader - Enemies to lovers but Fell is the only one hating - Your leg privileges are revoked, and Fell needs to wash his mouth with soap - Flowey is an equippable companion and decides to help you cuz he actually gets something out of it - My own interpretation of UnderFell (tho from what I've seen it doesn't really have a narrative anyway)

Fonttale by MegynHamilton

Fonttale is an AU where skeletons have a special power related to their font name. A Normal Font Comic Sans for example, can force people to laugh. However, Papyrus is a Horror Font and they're much different from Normal Fonts. This is where and why the story begins. Papyrus is a sadistic murder whose main goal is to protect his one HP brother Sans. By day he pretends to be an obnoxious idiotic skeleton obsessed with puzzles and spaghetti, but at night he teams up with Flowey and patrols the area for humans in order to collect souls to break the barrier. When he isn't doing that he visits the MTT Resort where his brother does his comedic acts and kills monsters he finds in the alley in order to keep Sans safe. Unfortunately as time passes and more and more monsters disappear, the "Resort Killer" becomes everyone's favorite topic...including Undyne's. When Papyrus decides one day to take a chance, something goes wrong and Sans discovers more than he ever wanted to about Papyrus, the Underground, and even himself. The line between right and wrong becomes a blur, and his relationship with his brother is tested as he tries to help him overcome his apparent madness. But is it really Papyrus that needs help?

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)

Bloodfall (An Undertale AU) by BlackStormWolf

Ever since the death of his younger brother. Things have gone downhill in the surface world for Sans. Alphys died a few months after Papyrus to a disease, Mettaton and Undyne, especially Undyne, had fallen into a depression. Flowey dissapeared into mt. Ebott, not to be found and Sans is fighting depression and insanity. One day, Sans discovers a suspect to his brother's death. A being that is trapping anyone who had either fallen into Mt. Ebott or stayed behind in snowdin for a while. Sans, along with Frisk and Undyne, go into the underground themselves to confront this being. They must encounter the Bloodfall that traps and kills anyone who dares pass by waterfall. (This takes place after a true pacifist run if one killed Sans in a Genocide run, but reset their game before getting to Asgore(I did this in a way to quit the Genocide route). This is if Frisk choses to do this the Pacifist way. I might make a Genocide one in Story Shorts. Also, My Sans is a human, but feel free to interprate him as a Skeleton if you ever choose to use this AU. Just credit me!)

I do NOT own Undertale but I do own this plot/story. Thanks to Toby Fox and the Undertale team for making the best game ever! Hope you guys like this story :)

It was a nice day in the underground today, until something...unexpected happened. Who are these new humans? How did they fall down in the underground? But most importantly are they a threat? Are they nothing but a bunch of dirty killers?...Or are they friends? This is my first story, quick warning but I do hope you still enjoy this as much as I enjoyed writing this.

Destiny [Echotale FRANS] {DISCONTINUED} by xxshumai

Sorry, but, I'm going to discontinue my book. I found out that the plot had turned boring. If you want, you can tell me what kind of plot you want and I'll try to do that. But, for the meanwhile, I'm going to mark this as DISCONTINUED. "N-no, that is impossible! S-she left me! She would have returned a long time ago! She would have been there when I needed her! S-she is already dead!" Sans, was traumatized when he lost Frisk. What if one fateful day come that he will meet her again? What does destiny have for them? What mysteries does this world keep? What dark and hidden secrets will be exposed? What does this world hold... for them? How will this timeline have a happy ending? We are about to find out... COVER IMAGE DOES NOT BELONG TO ME. BUT I WISH IT DOES. On October 19, 2018 this was 2nd on Gsans

No Chocolate - Chara X Frisk by phosphorus14

DRAMA, ACTION, BLOODSHED... Love? After erasing hundreds and hundreds of timelines, Chara is suddenly stripped of her abilities. She's forced to lead an everyday life in a world unknown to her, but that doesn't become a problem because Frisk, who just fell into the Underground, makes her forget everything, focusing only on their emotions and the chemistry between them. Chara and Frisk will go through good and bad together. They will have to protect each other from "the external factors" lurking in the shadows, and their teenage desires which they can't control~ All chapters labeled with "~" are exclusively lemon and unrelated to the main story. Go there if you want to have some fun ;) ""YOU HAVE NOTHING TO SAY HUH? THAT'S WHAT I THOUGHT." Frisk was uncomfortably close to me, even though she's a girl, she doesn't know that I'm gay as fuck for her." *IMPORTANT INFORMATION* - Chara (16/F) x Frisk (16/F) - Emotional and gruesome scenes - Sexual interactions and moments - Rough + gentle switch lemon

**COMPLETED**Finding Family(Underfell AU) by temoamelia

An Underfell fanfic. Can Frisk make it out of the Underground alive, and find what she was looking for? **COMPLETED 12/30/16**

Undertale : Secrets (REMASTERED) by ItIsComic

Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that, despite being so long ago, always finds a way to bite back. A past that defines who he is - but he longs to erase. A past that doesn't let go, it clings to him despite his endless attempts to escape. And when someone finally attempts to uncover the veil, and fails in the process, what happens next? This book is a complete remake of the original Undertale: Secrets that was made nearly 3 years ago. By remake, I mean that this book takes the general plot of Secrets and basically "tries again". This will reuse elements of the original and cut out the parts I don't like while adding my own new ideas, effectively creating a new book. Whether you liked the original or didn't even read it, I hope you like this!! Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 17 March 2024 Finished: Not yet! Undertale by Toby Fox

Sans X Frisk (An Undertale FF) by Turtleluv42

After Ethan (Frisk's older brother) broke the barrier and set everyone free, they went on a huge trip around the world to spend more time together. Frisk had no time at all to talk to her friends and to top it all off she had lost her phone on the first plane ride. Her and Ethan decide it's a good idea to go back to where all of her friends live after over a year of traveling. Frisk was so excited to see her friends again. Especially Sans. Before she left they shared their first kiss and she said that they could work out a long distance relationship but it didn't work out since she had no way of talking to him. She just hopes that they can become closer after not seeing him for what felt like forever. Most of this story will be in Frisk's POV but I might change it around sometimes. Frisk and Sans are about the same age and Frisk is a girl. Chara will be in this sometimes but she's not a genocidal maniac. Also Asriel is in this as well and Flowey was never a thing. One more thing. This will have some curses in it so if you don't like that, don't read it. Anyways, enjoy!
