My Gaster x Reader Fic Master List
Here is a composed list of my personal favorite Gaster x Reader Fanfictions on Archive of Our Own. They’re no particular order, I’m just going through the ones I have bookmarked on my account. I’ll mark which ones are complete and which ones are not. Enjoy, ya little sinners.
Starting this list off with a Mafiafell fic. You better believe it’s juicy. This one starts off with reader living an estranged life in a crime-ridden city, having fled her previous life and unsupportive fiancé. Gaster is the Don of the area. As per usual, opposites collide.
Status: Incomplete, but the author just came out of a very long hiatus a couple of days ago.

From The Mouth Of An Injured Head
Ah, now this one is a classic. Our main character is a humble woman named Alex living in an apartment and fixing tech for a living. She begins to have nightmares and see a creepy figure (Gaster) around her apartment. Once the horror of the situation fades and Alex learns who Gaster is, she sets out to free him from the void.

This fic was started recently. It’s another Mafiafell fic, and I particularly liked the med school aesthetic of it. Reader is a doctor in training who happens upon the bloody scene of Don Gaster, who’s been shot in an alley near her apartment. Will she obey her doctor’s oath and try to save him by any means, or leave him and save herself from getting involved with the Mafia?

Ok, this one is really cute. Reader has just moved into a monster dominated city in search of a job after she broke her leg in an accident. Things aren’t looking up, and they become particularly difficult when the head librarian (Gaster) of a library Y/N had fallen asleep in mistakes her for a book burglar. This fic has its fair share of tentacle jokes, fluff, and I believe spiciness to come.

I really love this one. All of these fics are equal in my liking, but this one in particular has a very similar feel to my own Gaster x Reader fic. It begins with reader, who’s going for an internship at her dream job after completing medical school. But her new boss, Dr. Gaster, and all his charm, become a constant hinderance to her concentration. Get ready for a fun time.
Status: Incomplete. I really hope the author gains a new spark to keep writing, but regardless, what’s currently there is great.

Here’s a one-shot I would never normally read, that I actually really liked. It’s an omegaverse fic. If you don’t know what that is, it’s basically where there’s a societal hierarchy based on alphas, betas, and omegas. Like I said, before reading this I wouldn’t normally read omegaverse fics or one-shots. This one is super long, and SUPER spicy. Check it out.

Reader finds herself connected mentally with a very troubled, yet very sweet scientist. Upon learning about Gaster and his void predicament, reader goes on a universe-wide journey to collect all the fragments of his soul and make him whole again. Reader and Gaster get to know each other in more ways than one along the way. This one is another classic. Incredibly sweet, romantic, and has an amazing ending. (I believe it also just got a second fic in it’s series!)

The fanfiction that started it all. This was literally the first Gaster x Reader I ever read. I read this one on QUOTEV back in 2017, yes that’s how long ago this was. This is an underground-set fic, where reader falls down, gets captured, and is brought into the HOTLAND science facility. At first Gaster brings her in to strip her of her soul and be done with it, but as they get to know one another he finds it harder and harder to hate her because she’s human. To this day I love this story. Enemies to lovers goals.
Status: Unfortunately incomplete. It stopped at an uncertain part in the plot, but it’s still very worth reading for the love story alone.
