Most Powerful Monster by thundersnake2375

I'm writing a fanfic on the popular game, Undertale. You fell down into the Underground at the age of 11, but little do they know that you had secret powers, at least until you got carried away. None of the pictures or videos belong to me.

Where do u think u're goin'? Yandere! Undertale Characters x AnyGender! Reader by Pandy999

The story takes place after Frisk sets free all the monsters in the Underground. After that, everyone was happy until...something horrible happened...

OVERTALE by UndyneKayKay

Hey guys! Welcome to my very first story called OVERTALE. It's a story about Frisk and the gang once they reach the surface, so if you haven't played the game this story will make no sense. This story is also full of spoilers so watch out!!! Also keep in mind that YOU, yeah, YOU the reader are Frisk. I wanted you guys to feel involved in the story so I wrote it so it's like you are the main character. Hope you enjoy the story! Thanks for TOBY FOX for creating the game and all of the others that helped Toby along the way . START DATE: December 9, 2015

Scars (Alphyne Fan-Fic) (Completed) by undertalekate16

None of the fan art in this book is mine all of them are credited to the artiest. What if Undyne and Alphys never met until Frisk saved the monsters and brought them to the surface. They have only met once and that's when Undyne was sent on a errand by King Asgore to give Alphys some letter from the king himself. Now that they are on the surface they all go to the same collage. Undyne and Alphys officially meet when Undyne goes to the bathroom and see three human girls hitting and attacking Alphys. Undyne and Alphys gets closer to one another and become a couple, but there is one problem Undyne's ex-girlfriend Lydia wants to control everyone and take over. There will be pain, love, abuse, losses and Determination. Also you'll get to see you two of my own character Lyida(who is Undyne's Ex- Girlfriend) and Allison who is in later on in the story. There is more to the story other then the secrets of Alphys and Undyne.

{DISCONTINUED} Finding Home | Undertale Fanfic by DeathByAnarchy

DISCONTINUED (for now, at least) • • • You and your younger sister, Frisk, fell into a hole atop Mt. Ebott. You didn't realize the journey you just began by simply falling into a mountain. A goat woman by the name of Toriel took you both in to care for you. Everything was fine until Frisk suddenly disappeared one day. All she left behind referring to her whereabouts was a note. On it, she had said something about her 'going back home'. But wasn't she already Home?

Undertale (pacifist route.) by kamira_220

Dive into the wonders of Undertale! Instead of Frisk being the main character, the MC if YOU dear reader. Yes you! I want to make it clear I do not own the game. The original game creator is none other than Toby fox. I hope this story is to your liking dearest reader :)

Her (Sans X reader) by AddisynDaKilla

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.
