The half breed and comic skeleton (Sans X Fem!reader) by FormSans96

This is a rewritten story of mine, I have changed the story to a X reader as well. I am a half breed. I am half human and half monster. I believed no one would ever love me like normal people would for each other. That was until I met this one skeleton, who has his own secrets. I can only hope.

The Sad Love that Kills by Eggthehappy

!WARNING! This story may include self-harm, killing, blood, and Happy pills! If you are sensitive to these things, do not read! 2 years ever since the monsters have been free and living in a city with humans. W.D. Gaster has been free from the void and has a stable life, at least, that's what everyone thinks. He is hearing voices and refuses to tell anyone. Grillby the bartender has been having huge success with his business but is having trouble finding some co-workers. Only for a night of talking did they change each other's lives. But they don't know why they're lives, and intentions are changing. It might be a match made in heaven. But it can also be something that might make the alliance between monsters and humans crumble. (Yes I made the cover.)

the Undertale Adventures by Nanmaku113

What, if you meet Sans and get a crush on him? You two would move into the underground and experience some funny adventures together! Get ready for: The Undertale Adventures ~Pibs

We Speak In Hands (Gaster x Female!Reader) by OreoDaSkeleton

Gaster is the current royal scientist, set with a mission to break the barrier and free monster-kind from their underground prison. His loyalty and persistence to the task is clear, since he'll make whatever sacrifice necessary to complete it. However, even a perfectionist can be blind to some of their own flaws. Gaster has a habit of pushing things or himself too far. An accident occurs in the lab. Whilst trying to save him; one of his lab assistants, Y/N, gets injured. Burdening himself with even more pressure and guilt to fix it, Gaster thinks that doing all of her work for her will cover up the incident. Still, the sad reality is that the damage can't be undone. Well, Gaster ends up spending more and more time with her. As a result, both of them gain an entirely new perspective of the other, they aren't just another monster in a lab coat anymore. Hey! It's Oreo aka Writer~San! Undertale, it's characters, and it's fanart do not belong to me. However, the story does!!! I hope you enjoy it! (^w^)~

× [Sickness] × || Undertale Fanstory || The Gasters/Skeleton Family by Nanaz_Nazmaki

One day, Sans fell sick. His sickness came out of nowhere and it cannot be cured no matter how many medicines Gaster gave him. Because of the sickness, Sans stayed still on the bed, just laying down or sitting on it under the blanket. The sickness can be seen from his face, half of his white skull was a little bit darker than the rest. Gaster and Papyrus had no idea what kind of illness Sans has, but they decided to take care of him no matter what, hoping that the sickness will soon gone either because of the medicines Gaster gave him, or disappears itself. But alas, The sickness gotten worse... -------- UNDERTALE (c) Toby Fox --------- This have nothing to do with Undertale's canon characters or story. This is just a fan story I made because the idea stuck in my head for a few while and I'd like to share it with all of you. So, enjoy!

Universal Surface Angel by Lithriel

Reader insert. What if W.D Gaster didn't just get split between time and space, but actually ended up in your world in an abandoned hospital you called home? Your were a young child he decided to use as experiments to test human determination in said world and breaks physical laws to test human possibility? He knows of the powers you gained from his experiments... all but one, this one allows you to tear realities just enough to teleport into them. Knowing of Undertale you felt bad for the monsters stuck below in their world and wish to help them, but something goes wrong and you end up going to certain AUs and helping them, gaining the attention of some bad skeletons who now desire your power for them-selfish-selfs.

Why? • Gaster!Sans x Human!Reader by sansisnotonfire

'When I was 13, I killed someone. By accident of course... It was the day I found out I possessed some type of power.' You kept it to yourself for years until one day it all went wrong. For your own safety you run away to the depths of Mt. Ebott in hope that the legend was true. But once you fell down you start to realise that this may not be the first time... "You've been here before, Y/N. And this time I won't let you run"

W. D. Gaster - An Undertale Story by RandomWriter1987

It all started when W. D. Gaster became the Royal Scientist of the Underground. Many monsters knew him, some even followed him. But one day, he injected himself with DETERMINATION. It caused something bad to happen. But it all took a turn for the worst when he fell into his creation. When he fell into the CORE. When he found out the truth. When he drifted in the darkness. Forever. Undertale Characters and Undertale by Toby Fox Cover Art by me.

[Sansxreader] A Whole New World *UNDERREVISION* by Mousington

UNDER REVISION (Check out Memories!) BTW- Sans is human in this. The story will explain. He has a sister named Chelsea and he is your "cousin".This story contains legal age drinking, a hint of suicide and might have a lemon if I decide to write one. Idek (Future me here, fyi- I'm not writing a lemon EVER in my defense I didn't know what they were but my friend said to put that soooo....) [^well variety IS the spice of life soooo };) I might...] ENJOY
