Gasterxreader Stories

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^)~

The True Gaster x Female Fanfiction

Author's note: Brrrr this is my first ever fanfic I've ever made sksksk and for the first time, the reason for this is bc I got an idea for Gaster X reader fanfic! I guess I got inspired by other Gaster X reader fanfics or then it's (was) just an alternative version of my OC Thiara (whose a skeleton) "arrive" to the underground rather than canonically/officially being already in there, don't know! it can be both^^ But my god- I'm a bit scared tho lol since I've never done this before, I don't really want to make the characters wrong or something (might be off-character idk),,, But uh- yea, read below for the story description now,, -- (Y/N) is a skeleton who weren't trapped underground like the rest of the monsters when barrier was casted, but instead hid with her/his/their mother and her/his/their twin, but were one day found and captured.. or at least (Y/N) was. Their family wanted to rescue them, they all managed to run to the mountain where the barrier was casted, but the humans had catched up, only (Y/N) was able to get through the barrier to safety.. or rather pushed in as their rest of the family was killed. From there (Y/N) was found by queen Toriel and were taken for better healing to a certain royal scientist; W.D.Gaster! The story continues on..... -- All the Undertale characters belongs to Toby Fox!!! Reader belongs to you^^ I might give out some additional OCs or not, depends! Now babai~ Edit: I'll be using they/them pronounces for the reader-- might've forgotten to mention it before publishing anything,,,

Hi guys! So this is actually my first time writing a adventure story (and xReader), so I am kind of sorry if it looks crappy!! ****** A long time ago, people were missing when they climb up Mount Ebott. They say there was magic, got lost, or even died. But when you discover the secrets of the mountain, you will get attached to it, and even maybe meet a new 'friend'... ||an W.D. Gaster x Reader fanfic|| •I do NOT own any type of artwork that is included here in the fanfic, all art goes to thier respective owners.•

woooaaaahhh

The remastered version of my highest read (and only visible) story! A story of a young woman in her early twenties living in the small town of Cameron Mines, residing just west of the fabled Mt. Ebott. Everything appears to be calm and normal in her small town aside from the still growing number of missing miners, all who went to dig around the highest peaks of the mysterious mountain. As her curiosity grows she takes the chance to explore this forbidden earthen foe. What she finds is far more expansive than she once imagined. (Note: This does not take place within the canon storyline of Undertale, it takes place in a modified Fannon Undertale universe) (Cover art by Meammy on Deviant Art)

You've always have had a creepy smile, and it doesn't help that you have these scars on your face now.... It doesn't matter though, you're fine with it, and he's happy too... Simple Gaster X Reader fic, I hope everyone enjoys!

This story is about a girl named Y/n L/n. She barely managed to graduate highschool because she was one point away from failing. One day she decides to be a test subject to earn a little money on the side. She winds up in the company of monsters. She happens to meet a certain skeleton and her story goes from there. Disclaimer: I do not own Undertale. Undertale belongs to Toby Fox.

Just a regular girl... until that one day... Xalva just wanted to go to school... finish college... and maybe become a... rocket engineer. Her whole life she had looked at rockets with awe and wonder, not thinking 'I want to be in one of those' like most, but rather 'I want to build it so people can go to space in that Thing'. Type. Rocket engineering wasn't easy, but who ever said dreams where easy? But that all changes when she has a strange visitor... Who is he? Why does he speak in this font? And how did he get here? ---- -Notes- All characters except Xalva belong to Toby fox Xalva is her nickname, her full name is Xalvadora Moors, meaning savior in Spanish. This is kinda a gaster x reader I guess if you count Xalva as a reader. I always kinda felt uncomfortable when the name was y/n :/ Xalva is mine If you use any ideas plz give credit Thnxs This is preferably for people 10 and older. You might not get it if your younger, but it doesn't really matter, this is going to be an E for everyone type book, no weird stuff. ALL PICS ARE NOT MINE EXCEPT THE COVER!!! I drew the cover, but the rest I found on Google. Unless I specify, they are NOT mine. #1 gasterxreader 9-02-2021

I'm writing this for me as well for you Uhm I have no idea what I'm doing so yeah- I'm trying to make it inclusive and crud so PLEASE be patient!! TikTok is @gastermybeloved lol- Cover is by someone, idk, but google didn't say so.. If they're on this app and want me to take it down, I will. Onto the actual book description: ~~ After the incident, you lie in a limbo. No idea what happened or where you are but you're there and confused. And then your here. In your favorite game's reality. And there he is.

You are about 15, Gaster is 17. In this Gaster is an older brother to Sans and Paps. Asriel is about 6 along with Frisk and Chara, who show up later. You and Sans are best friends, but Gaster is amazing! At age 17 he is the royal scientist and you hope you can help him out.

'Filled with power the Queen will rise but loving monsters led to her demise. (Y/n), Queen of Darkness' Frisk stared at the plaque and took a look at the tapestry. A girl with spade cheek marks, around her 20s held a parasol surronded by roses. She was accompanied by a monster who Frisk couldn't recognize but seemed oddly familiar. The two bore matching outfits, the girl a short sleeved purple dress with a white undershirt, a cresent moon decorating it. She wore long purple gloves as well. It seemed edwardian. The other wore a dark purple coat and pants. A white sweater underneath. Maybe they were a couple or something. Frisk shrugged at the thought and motioned for everyone to follow them further into the castle, missing Asgore's, Toriel's and Sans' long stares at the tapestry. "Is that....really them?"

Hope You Guys Like It! its my first book I will update as soon as I can
