You were always a curious child. One day, your curiosity took you too far. You lived not to far from a mountain, MT. Ebott, and always wanted to see what was on the top. Your parents had told you stories about the mountain and you had always wanted to see if they were true, being the naïve child you were.

One day, you reached the top after a while of climbing. You looked around, not realising where you were walking and fell into a gaping black hole. 

You woke up to a soft voice of a goat-like monster who, ever since that moment, took care of you and loved you. She taught you magic and all sorts of recipes. Everything she knew and you loved it. 

But what happens when you grow up more?All Rights Reserved

Determination (Sans X Reader) by viralwigs

Next person to add this/comment gets c l o c k e d ~ When Frisk goes missing, you decide to look for them, only to fall into Mount Ebbot. You discover that you have the power to revive dead monsters. Wow, that's a lot for one person to have to deal with in a 24 hour time period, am I right?

A Strange Feeling (Sans X Reader) by Sak423

Do not expect consistent updates as life gets busy 🙃. This is rated mature because of strong language. You are a 24 year-old in college and have loved Undertale since the beginning. You enjoy all the aspects of the game; the story, the lore, the music, the backgrounds, and most importantly the characters. You've started having a strange, almost malicious feeling related to the Genocide run and that creeps you out. So, you start a pacifist run and after a while, you fall asleep. You wake up in Undertale and thus begin your new journey. Through your travels, the strange feeling comes back, but as a different emotion. Perhaps the only one that can help you with this feeling, is a certain punny skeleton. (I tried my best I'm not very good at summaries 🥲.) (Also I am so sorry for the kinda weird writing this is my first time writing a story. So I welcome constructive criticism.) Started: January 26, 2025 Ended: ???

I'm The Apprentice: Underfell Papyrus X Female Reader by JaysDreamCatcher

EDIT: READER AND PAPYRUS ARE BOTH IN THEIR TEENS!! WARNING: BOOK CONTAINS SWEARING/CUSSING AND VIOLENCE Just before she passed away, my grandmother told me about the monsters who lived under Mount Ebott. My mother hated everyone. My father died in the war of the monsters. My grandmother decided to whisper to me: "Promise me, You will find, A better family. One who will love you, No matter their duties. I will love you too, I will be watching you. No matter your choice, Let me hear your happy voice." So that's what I did. Her words went through my head as I climbed the mountain, hoping that a monster could help me. - "Sans flinched as the shouting downstairs grew louder. The ropes around my wrist seemed to grow tighter as I struggled, hoping to break free from the monster stomping up the stairs angrily. As Sans stepped back, his door was smashed open. I took one long look at the figure standing there and instantly knew: this is why I am here." - (SLOW STORY! MANY SLOW CHAPTERS BECAUSE OF DETAILS)(COVER ART NOT BY ME!)

Sans X Reader // You're Too Punny by MySmolChemicalBean

Smol thing I guess. I don't own Undertale (obviously), but I do own all of the art in this book (as the first A/N states). This is my first fic. I update as often as I can, especially on most weekends. Don't be afraid to comment if you have something to say.

Fight or Mercy | Underfell x Abused! Reader by YuniccAfton

[2nd book] ((COMPLETED)) {Undertale AU - Underfell} [WARNING:ENDING AND PLOT IS VERY CRINGEY] "Long ago, two races ruled the earth, the Humans and the Monsters. One day, war broke between the two races. Many have fallen to serve their kind. Years later, the humans were victorious. With their magic, seven of their strongest wizards sealed all the monsters underground with a magical barrier. Only a human soul could pass. Mt. Ebott 201X, they say those daring enough to climb up the mountain.... never return. " "Leave them, Y/N! Run! " ___________________________________________ I'm a Undertale addict. I freaking love the story line and characters! One of my favorite AUs is Underfell so I'm finally making an X reader. Also, if there are wrong spelling or grammar, please tell me. I'm using GoKeyboard. Enjoy my Crappy 2nd book!

{DISCONTINUED} Finding Home | Undertale Fanfic by DeathByAnarchy

DISCONTINUED (for now, at least) • • • You and your younger sister, Frisk, fell into a hole atop Mt. Ebott. You didn't realize the journey you just began by simply falling into a mountain. A goat woman by the name of Toriel took you both in to care for you. Everything was fine until Frisk suddenly disappeared one day. All she left behind referring to her whereabouts was a note. On it, she had said something about her 'going back home'. But wasn't she already Home?

Sans x Reader | Empire by rottenentity

(Adult Lazarus here - I wrote this when I was like 14 years old. Forgive me.) Sometimes life gets to the point where you feel like you're a paper airplane. One minute you're soaring, feeling as if nothing could ever get you down. But then the next thing you know, you're falling slowly and nothing that you can do can possibly help you. You end up falling and crashing into whatever's below you and the heights that you had once reached. Then it starts all over again - becoming a vicious cycle. Someone picks you back up and throws you, making you soar yet again. But then they watch as you fall, not stopping you or saving you from the hard impact you meet with the ground. The process repeats itself over and over and there's no way you can stop it. After all, you're made of paper - you're delicate, fragile. You're thrown, you soar, you fall, you're picked back up, then it happens all over again until you break - becoming bent and broken from your head to your toes. Until you crash so much that you're ruined - then you're thrown away. At those times, you know that you at least have one person who will fix you. He calls you his queen, as any king would whilst in power of the empire you both strive to build together. This person is your home - your empire. - #6 in Quotes [03.12.21] - #2 in Sans [10.21.21] - Undertale does not belong to me. - Artwork/Music does not belong to me. - Also, I apologize for any of the spelling errors. I type quickly and so I do not really realize if I misspell a word or two. Sometimes I do go back and edit out the mistakes with spelling and such.

A Tree, For Us (Sans X Reader) by TheAbandonedQuiche

CONTAINS SPOILERS FROM BOTH PACIFIST AND GENOCIDE RUNS After a horrible situation, I (Y/N) scaped from home to avenge my (sibling). In a failed attempt, I got lost and fell through a hole, in there I found another world... "the underground". I meet many friendly monsters, one, specifically, changed my whole life.

Heya Princess~ (Echofell!Sans X Fem!Reader) [Rewrite] by k44rds_and_J0kers

Y/N the golden child, the star of the family. Y/N never really felt like she was part of her family despite her loving relatives. She felt like they only loved her because of her accomplishments, magic powers and nothing else, while in reality that's not true at all. They just didn't love her the way she wanted to be loved, so she decided to just run away from it all.... MT. Ebott that stupid legend where if you enter you basically never return.... she thought it was all made up to scare kids but boy was she wrong. and she was in for a treat "Heya princess."

Goodnight, Kiddo... (Adopted by Sans! Reader Fanfic) by TheShortSensei

You are an orphan, abandoned by your parents at birth. You've lived between countless foster families and a dreaded girl's home for as long as you can remember, because nobody chose to adopt you. Now, you are fifteen years old, and you decide to run away. Monsters have been living on the surface come four years now. What could become of this new adventure? Heyyyyyy! TheShortSensei here! I strongly suggest reading my former Undertale x reader book, When Spaghetti is your Life, before looking at this one. This book is a continuation of that one, so there may be spoilers if this one is read first! I will probably be using female-based pronouns, but I don't want it to be so gender based. Have fun, guys! Thank you for choosing to read this trash. Please comment and tell me what you think! P.S. If you're still reading, you get an invisible gold star sticker from yours truly. Well, what are you waiting for? I already gave you that sticker, didn't I??
