I used to be good friends with them but once I received the trait fear, I was scared. I couldn't be around them. They'll hate me. Sans X reader X SS Chara

It all starts with an experiment. Taking a human soul and a lifeless marionette. Fusing them together. The result? A living, sentient marionette. Her name is (Y/N). Many more experiments and tests ensued. After she has decided she has had enough of this, she runs away. She ends up falling down into the mountain known as Mount Ebott. She discovers the monsters. She makes friends, enemies, but most importantly... a lover. A very punny one at that. Come and join us as I tell the story of (Y/N). Undertale belongs to Toby Fox. (Y/N) belongs to you. Cover art made by me. Also FYI extremely slow updates.

[THIS IS A SEQUEL TO MY OTHER FANFIC "WHEN TWO SOULS MEET!" If you haven't read it, I would highly suggest it--the story won't make much sense otherwise.] Sans has finally found someone he can trust--Frisk's sister, the eighth fallen human. After months of step-siding and awkward interactions, the two are finally a couple. Things are slowly falling into place--there are no more resets, and Chara and Flowey have been a lot more quiet in the last few months. But things can't stay this way... can they? Note: The story was put on hiatus early on, and updates are now very sporadic. Despite that, it's still a labor of love!

The cover created by me. (DO NOT STEAL IT AND CLAIM IT AS YOUR OWN.) GZtale belongs to GolzyBlazey/Golzy Blade Dee/ GZ Studio Some a bit of reference from Glitchtale belongs to Camila Cuevas (The reader is actually a female in this fanfiction) ------------ You are the only one with pink soul and no one knows about your trait. (the pink soul) Even you also doesn't even know what your trait is and found out in the Human History book. (Some glitch erase your memory knowing your trait for some reason...) Lets start off about your life. Your father passed away during the accident and your mother married to another guy, stepfather. He was mean and cold to you whenever your mother is not home. It changes your life when another bad luck happen in your high school. So you decided to pack some important stuffs and climb Mount Ebott with your best childhood friend, Akumu. You met a child and the skeleton along with some friends. But, you never knew something bad gonna happen further in the underground... ********* Եհҽ ɑժѵҽղԵմɾҽ íղ Եհҽ մղժҽɾցɾօմղժ աíԵհ ɑƘմʍմ... ********* Bare with me that this is my first fanfiction I made. If there's an error and some more broken English, I am sorry xD ~2017~ (There are some plots from Glitchtale which it doesn't make ANY sense so if you don't like it, don't read it)

Glitch and Anti-Virus, a.k.a Anti, never asked to be alone. They had no choice. They used to be normal. Their names were Gabriela and Annaston, a.k.a. Gabby and Annie. They were sisters that would play together, and they both worked for Dr. Gaster. But when an experiment went wrong, they became corrupted human-monster fusions, banishing them from the world of Undertale and into their own little world, with no memory of their true selves and the ability to manipulate the very code of the universe. However, when Glitch hacks herself a way to their previous world, things start getting a little crazy, and with Frisk's help, Anti has to stop her sister and SAVE the world... ...but can she do it in time?

This is the rewrite of my older story daughter of Gaster. Also the cover isn't mine ~Warning~ This book contains my head cannons so if you do not agree with something then go find a different book Gosple is a human monster girl who was made before Sans and Papyrus. Even Gaster himself doesn't know how she became human
