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!

Undertale X Reader [In Remake] by Cat_Maipie

Let's get to the point shall we? So let's look at the list here... You're a... no information? Hm, interesting i guess, I'll have to base it off my observation. Whatever, you're a human, well kind of. You're a human and a monster at the same time, more like in between. Let's say... player? Better than nothing i guess. You're your own person. Sometimes you control frisk, sometimes you don't. You can also move through timelines, and also universes but that may be too risky huh? You'll find more about it soon...

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.
