Dual Stones - Undertale Fanfiction (COMPLETED) by IcyDuelist

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!!!

It's kind of a Sans x reader. I named the character. Oops. Welp, here we go! This has potential I promise. Just give it a chance. Please.

Reset (Sans x Older!Frisk) by error-code-707

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),Fanart

Timeline for You, A Chasriel Love Story | Undertale AU by AshdorCrush

[This story is officially completed, and any A/Ns have been removed for best reading experience. Enjoy!] A month after Frisk freed all monsters, Chara and Asriel return to life. Life on the surface went well for a few years after that, but something resonated with Asriel and Chara. Chara and Asriel like each other, but neither of them know about it. But when someone threatens to break their bond, things start to fall apart. Can best friends really love each other, or will they be destined to HATE each other? This story will contain vulgar/sexual language, suicide, rape, violence, gore, and blood. UNDERTALE, its characters, lore, and locations belongs to Toby Fox Custom characters(OCs) made by me

Saving Them (an Undertale fanfiction) by fucking_username

The barrier is broken, monsters and humans are living in peace, everyone is happy except for one person. Frisk has been getting waking nightmares about not saving Asriel. They want to save him to erase all guilt and to be with their friend. But Asriel isn't the only one that needs to be saved. Something, someone lurks inside Frisk's soul. Someone deadly and has a hunger for power, and can kill anyone they want. A/N Frisk and Chara are both gender ambiguous in this story. Also there will be a little bit of Frisk x Asriel in this story, but this is not a Frisk x Asriel fanfiction. Credit to @karinacat59 for the cover. Undertale belongs to Toby Fox and none of the characters are mine.

Gaster belong to Toby fox. the other characters from Undertale has well. only my ocs and persona belong to me. So has the drawing you will see in it. if I even remember to put some in ^^"

Bone-afied Security Guards by ZeconZimorian

Title: Bonafied Security Guards summery: Frisk is the monster ambassador and is in need of protection. With the constant threat of human assassins, mobs, and the organization known only as the 'Saints of Purity', she will need the best. With the aid of the Skeleton brothers and her natural psychic abilities, everything should be fine. Right? Well it might if it wasn't also for the fact of her powers going crazy, her body changing more and more into that of a monster, and her relationship with a certain pun loving Skeleton. Things are just warming up. ( Please note none of the characters are mine, all belong to Toby Fox. Story idea is mine however)

For many years, Frisk never once knew about Valentine's Day. What?!! That's probably what you're thinking. Anyways, Frisk has a huge crush on a certain skeleton who's also crushing on someone else. Will she be able to confess her love to him and live a happy ending? Also...Frisk is a girl in this story ;) UNDERTALE DOESN'T BELONG TO ME. IT BELONGS TO TOBY FOX. None of the used pictures&gif's are mine. And that's about it. Plz follow, vote, and comment in my books. I'll be happy to hear from you. Buh bye!!!!

"I feel that I'm living in a dream right now, and any moment I'll wake up and find myself back in another nightmare." I say, eventually. "Welp, if you ever do, just remember, dreams can come true," he tells me, bringing my face closer to his. - Chapter 7 The reset button. Just the word is enough to give Frisk nightmares. Temptation grows strong inside her, but if she were to disappear, would everyone else be saved from the peril that a reset brings? Cover art done by me, and I do NOT own all of the characters in this story. Undertale belongs to Toby Fox, but some of the characters in this story belong to me.

undertale sans x reader oneshots (english) by paranoidvoidart

well this is my first x reader book hope you guys like it i accept request

~~~ [COMPLETE] After being set free from Frisk, Chara finds herself shoved into a new life that she didn't ask for. She's cold and distant for days, void of a SOUL and seemingly proper emotions. However, there's a certain somebone who refuses to tolerate it anymore. Unlike her, he's kind and unfortunately, always around. When Chara finds herself dealing with unrecognizable feelings, he knows just how to help her. ~~~

Undertale is going to react. This will not be entirely canon and will include aspects of what I believe (backstories, ect.) I do not own the cover and I do not own any of the characters.

~'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.'~

He's Mine (COMPLETED)(Yandere Papyrus) by BubblyShip

(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.

One By One (COMPLETED)(A UnderTale Genocide Story) by BubblyShip

(UnderTale completely belongs to Toby Fox, I in no way helped him create the game. I'm just simply a huge fan and want to write a short Genocide route fanfiction. Also, this story is COMPLETED, so don't expect any more updates. I also drew the cover.) A long time ago, the first human fell down into the ruins. A monster named Asriel came to help her, and quickly accepted her into the family. However, a disease fell upon the young child, and she died shortly after. Years later, a 7th human fell down into the ruins. However, the spirit of the first human took over her body, and decided to take out her revenge on the monsters of the underground. This is a True Genocide Story.
