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^)~

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,,,

Your a neko: (deal with it) your 'Master' has thrown you into a pond that had a waterfall going to the underground. After falling 1000ft down, you landed on a soft yellow flower patch that broke your fall. (Yes there's a small patch of buttercups on a raft.) and you were terrible afraid of water, what will u do?

Gaster x reader Reader named Sage bc Y/N is cringe /j I have writers block don't bully me

So I was really inspired to keep writing stories by someone who commented on one of my stories. You know who you are. I've been on here a lot and I've seen people actually reading my books... I'm so happy ^_^ Anyway... A backstory and How to read an X reader will be the first chapter... This'll probably end up being a lemon cause, that's all I know how to write... xD So... Enjoy!

(Cover art by Zarla on Deviantart) I'm annoyed that people keep mischaracterizing my interpretation of Gaster so I'm making short stories as an attempt to characterize him 😁 I'm Gaster's wife and partner irl On that note, some of these will be x readers cuz I'm a filthy, filthy simp <3

still need a proper thumbnail "do you think this will work?" he questioned, concern coating his face as he stared into your eyes. "I don't think, I know." you replied, confidence weeping from your soul.

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.

Sequel to the book Subject 108. Six years after leaving the underground,the dreams of your once beloved return as well as the calling of the mountain. But, the return of monsters and your own bitter secrets prevent you from knowing the whole truth. Will you ever be free from his grasp? (WARNING: GORE, SEXUAL SCENES AND STRONG LANGUAGE)

Watching your determination being extracted from your soul. Fills you with fear.

'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?"

your name is Y/N and you got transferred into a void filled with tall skeletons and you are very confused...but...not afraid

(Cover drawn by me) The angels weren't supposed to pick sides. They were created for one reason and one reason alone. Protect the humans from any threat. There was no such thing as a grey area when your entire worldview was supposed to be black and white. And yet yours ended up shifting. The things that once felt right now didn't and you did the one thing no angel ever dared before. Went against God themselves. Your punishment however, ended up changing your life in a way you could have never expected. And it was all thanks to a family of three skeletons and a fateful meeting that couldn't have gone worse.

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

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!

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)
