Undertale:Secrets
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!

Undertale: Tales from the Dreemurr Family
Join Frisk, Chara, Asriel, and their younger sister, Aria, as they share many happy moments together! 11 months after Frisk's most recent True Pacifist Run, they, Chara, and of course Goatbro himself (AKA Asriel Dreemurr) receive a wonderful surprise in their new sister, Aria. Eight years have passed since then, and the four children are having all sorts of fun with each other! Comment if you like the story, or if you have an idea of what you'd like to see the Dreemurr family get into! Disclaimer: I do not own the game "Undertale," or the characters that appear in the game. Aria is my OC, and is not an actual game character. Note: Updates may be irregular, due to the fact that I have no set schedule. Also, I may edit chapters that have already been published, so you aren't alarmed when a chapter changes.
What Went Wrong?
~'Disclaimer: This story has a lot of profanity and covers some very very intense or touchy subjects that may disturb some readers. You have been warned.'~ ((Unedited)) After Chara fell into the Underground, they met Asriel a monster inhabitant of the Underground. Soon after that, Chara joins a new family, but their ambition to keep everyone happy goes a little overboard and Chara is flung into a reality of destruction and hopeless wonder. Then many long years later they meet the beloved Frisk, who fell into the Underground, similar to themselves. Eventually everything Chara thought they knew correctly is turned upside down and they as a person are changed forever. ~'The game Undertale belongs to Toby Fox and some of the dialogue is ripped straight from the game itself, too.'~Complete
Reset (Sans x Older!Frisk)
There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),FanartComplete

Dual Stones - Undertale Fanfiction (COMPLETED)
Duska has something most people would call a traumatizing childhood which she only escaped from a few months ago. Now she finds herself beneath the very mountain she was born in with monsters around every corner. She decides to start her life again here, in the house with Papyrus and Sans, but monsters don't live the most ordinary of lives either. Duska's past is catching up with her but the wall of friends in front of her may be hit by the impact first. No pictures, videos or any other media belong to me unless specifically said. Will have some swearing in it. Undertale belongs to Toby Fox. Thank you for creating such a beautiful game! I FINALLY FINISHED IT!!!Complete![Undertale - Fighting To Stay [Frans] [Book 3]](https://img.wattpad.com/cover/99001605-256-k835905.jpg)
Undertale - Fighting To Stay [Frans] [Book 3]
So, monsters and humans have been living together on the surface for quite a few years now... That's an accomplishment! No resets, no new timeline. Just a future continuing forward like everyone could have possibly hoped for. However, not everything is hopeful. You can't expect to live a life where everything is sunshine and rainbows. Even with no longer having the threat of someone like Chara, things can still happen when you least expect them to. You can't always have your "Happy Ending".Complete
He's Mine (COMPLETED)(Yandere Papyrus)
(UnderTale rightfully belongs to the amazing Toby Fox, I am not creative enough to make that masterpiece. There is a person named symphysins who drew some work of Yandere UT! Papyrus for Sans, and I really liked the idea of a creepy UT! Papyrus and decided to write a short story on it. Also, Frisk can't reset, she never had that ability. The cover is my own art.) "Why is everyone I date dying?" Sans asked, covering his eye sockets. "Am I cursed or something?" "I'm sure you're not cursed, Brother!" Papyrus said, patting his back. "T-There might b-be a Yandere on t-the l-lose!" Alphys piped up. "A Yandere?" Sans asked, tilting his head. "What's a Yandere?" ~~~~~~ Sans felt like something was wrong. Everyone he tried to date ended up dusted, and he couldn't figure out why. So, when Alphys explains to him what a Yandere is, he realizes he might be someone's Senpai. Determined to stop this endless cycle, he teams up with his friends to try and find this psychopath. If only they knew he was closer than expected.Complete

(Dancetale) Better Dancing Together - Sans X Reader [DISCONTINUED]
[16/08/17] Edit- Okay. Warning. This was written carelessly? The grammar isn't too bad, but it isn't too great either. This is also discontinued. Go to @Lilliyona to see the continuation. Bad jokes were also made cause I didn't know how to do jokes. So there's a lot of cringe, probably. It isn't as bad as my older books, but it's still bad in my opinion. That's all. Goodbye. Heyo, too lazy to explain anything! So yeah, all I can say is just, this will be in High School so meaning teen Sans and everyone are teens except for Toriel and Asgore! And yes it's Dancetale like what it says in the title! Chapter one might wouldn't sound like it would be Dancetale, but trust me, I have plans! And I know that, it also may sound like another cliche type of Highschool crap, but I promise things won't be like that! Hope you enjoy~ I do not own Undertale nor Dancetale. I do not own the art for the cover. (Edit- Warning: One New Chapter Every Week Or Two. Might Contain A Few Swearing Here And There. Cringe At The First Few Chapters-in my opinion now that I've grown up a bit-.)Complete
Undertale: Genocide
"In this world, its kill or be killed" - Long ago, two races ruled over Earth: HUMANS and MONSTERS. One day, war broke out between the two races. After a long battle, the humans were victorious. They sealed the monsters underground with a magic spell. After the war, the monsters retreated into the deepest part of the Underground, which would be called, "Home." - Note: In chapter one i NICKNAME frisk "Sam" Due to the fact you dont figure out their name until the end of pacifist so i had to put a nickname to make it easier to write and read. Sam is a neutral name so it should be fine. - NOTE: All lines with this symbol " * " is going to be in Wing Ding font in the final release of the book. But for now, it is already deciphered for you! - *So yeah!

Posttale (English UT/DR AU)
This story takes place after the events of the pacifist ending of Undertale, where all the monsters have already left the underground. However, that won't stop problems from starting again; Frisk and his friends will have to face a new threat. DISCLAIMER: This story is based on the fact that the first human fell underground in 2015 and the last in 2060. Here, Deltarune is a sequel to Undertale; therefore, Posttale is not a copy of TobyFox's creation, but an adaptation, or what is also called an "AU." Because of this, there will be things that are different from canon and adapted to my personal preference, with no intention of disrespecting anyone; for example, the gender of the humans: Kris: M Chara: F Frisk: M Don't like it? You can leave. Understood? Great.
