An Undertale story that came from me venting, and now I'm sharing it for some reason! This sort of takes place after the game, where Sans finally breaks. Tw: self harm, depression, and suicide themes. I told you it was venting. Stories like this have always helped me get through things, hopefully mine can do the same. Feedback would be great!

Something happens to stop the normal flow of a Genocide run. An anomaly appears...but maybe it's not the one you think. *Trigger warnings: there might be some violence/threats/feeling trapped and self-harm at some point

A collection of inane nonsense (ranging from Error being reincarnated as Palette to Dust finding a new love for the color pink) circling around the many AUs and Multiverses of the Undertale world. Some stories will be connected; Others will be random one-shots. Stop by and see what treasures, or horrors, you can find.

For every world that exist thousands of possibilities of little changes that can create a new one in its place. It's a scary thought that can keep me up at night. Since in my nightmares, I can see those possibilities. That for every dark story theirs a brighter ending to be made is what keeps me going. That as long you are determined and willing move forward you are sure to make it

If she could go back in time she would grab that USB, jam it into her computer and download that stupid game. To hell with exams and getting into uni. This was a matter of life and death. From before the war to its aftermath and the game.

After countless Genocide Routes, a second human falls into the Underground. Will they be able to stop the genocides? And what will happen after they defeat them? (Note: the original DoubleTale fanfiction was written by XWolf26. Also, like everyone else, I do not own Undertale.)

It's a universally known fact that humans and monsters have SOULs that give them life, but SOULs are much more complicated than that. This is the culmination of over 1000 years of research into SOULs neatly condensed and written in modern language. This is my take on what SOULs are all about with references to my AU story and my own flair added in! (Bi-weekly Uploads)

Eran las primeras vacaciones que se tomaba. Sans pensó que serian relativamente tranquilas, claro, si se ignoraba los gritos de su hermano, Papyrus, y el enamoramiento de este con Frisk; la molesta y deportista Undyne, intentando que se levantase del sofá y moviese el esqueleto; además de la familia Dreemurr, conocia a Toriel, pero sus hijos eran otra cosa.

I wonder what will happen when these two get to talking... (18 )
