Love Me Instead [Sans VS Gaster!Sans X Reader] Part 2 (EDITING) by PineappleGalore001

Please read part 1 if you haven't! When a mishap in a reset happens and a character from another version is transported into the current world and timeline, what happens? Gaster!Sans, bad-skele-boy from EchoTale is confused to see that he had landed in a different, yet familiar world: Undertale! Apparently, in meeting with his 'original' version, they seem to be OK with one-another, UNTIL... (Thank you, @yourebluenow for the cover!) If you have not read part 1, look for it! It has the same name and cover, but without 'Part 2' on the title.

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

This is when sans and papyrus are kids and sans finds the ruins door and an unexpected visitor on the other side ;) (Soriel) (if gaster was like a dad to them xp) And yes I know the cover is spelled wrong XD

The Original (An Undertale Fan Fiction) by SkeleMatcha

Y/n is Sans and Papyrus' older sister. She has found a way back from the void and has to learn how to adjust to life back in the real world. She was the first to be created by W.D. Gaster, but a malfunction happened during her creation and she turned out to look more human than skeleton. Her only resemblance to a skeleton is her nose and her pale skin. Pictures do not belong to me.

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"

I WROTE THIS WHEN I WAS 15/16 I'M REALLY SORRY LADS Chara is stuck in a spiral of Evil. Sans and Frisk are happily living on the Surface. The LOVE is gone, and replaced with love. All Gaster needs to do is interfere with a moment.

Underfell Skelebros backstory! Technically a prequel to my story, "A Three Way SWAP," but you don't need to read that to understand what's going on. Takes place in the world of Underfell. We learn what happened to Papyrus to make him so cold and distant in Underfell. WARNING: MILDLY VIOLENT AND MENTIONS SUICIDE. GETS A LITTLE DARK. YOU'VE BEEN WARNED.

Exactly what the title says... Undertale one-shots! Cute ships, silly scenes, anything I feel like writing. Literally me just chucking ideas against a wall like a bowl of spaghetti, hoping something sticks so I can lick it off the wall... [written 2017]
