outertale sans underfell underswap undertale

You released all the monsters from the underground. After that you heard a strange noise. You followed it until you reached a black portal from the world.

You felt curious about it and went through it. After a some time you found yourself at the beginning but as you explored it, you felt that you were some where.

Across the ruins, the snow, the galaxies. Find your way out.

Silently Sleeping (Underswap!Papyrus x Reader) by GamerQueen2002

Underswap!Papyrus x Reader And some Fresh!Sans x Reader -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- It isn't hard to slip into a dream. You're happy with what your mind makes up and you stick with it until you wake up. Nightmares are hard to sink into. Death, tears, bloodlust, screams of terror and agony. You eventually wake up crying and wondering why your head would come up with something so sadistic. You're not in a dream. You never were. It's always been a nightmare. Always. -_-_-_-_-_-_-_-_-_-_-_-_-_- "My heart fills so... empty." "Please don't do this, (Y/n)!" "I'm sorry I caused so much pain... but we both don't have to suffer anymore."

Most Powerful Monster by thundersnake2375

I'm writing a fanfic on the popular game, Undertale. You fell down into the Underground at the age of 11, but little do they know that you had secret powers, at least until you got carried away. None of the pictures or videos belong to me.

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: ???

$When Two Souls Collide {Sans x Reader} by _Usagi_Kitsune_$

You've always felt gravitated towards Mt. Ebbot, even in childhood. You don't know why, but it feels like you're being pulled there by some unknown force. One day, when exploring too far, you fell down into Mt. Ebbot. Along your adventure into the Underground, you meet a lot of people, but there was one who caught your eye... {WARNING: May be spoilers for True Pacifist Route of Undertale, maybe not, idk.}

New Family (Undertale au's x OC) by Juniperlives43

*Not completed (on Haitus with this one) just trying to prevent wattpad from deleting it* A teenage hero has fell down into the underground known as undertale. She is injured and stays away from the monsters that live underground for their own protection... because she is being chased. *give credit to all artists for the cover and any art I use in this. Great work! And the au sans belong to their rightful owners*

(WARNING: Curses and sadness if your sensitive to both or one of these dont read it or you'll get more sensitive XD ^^)

[VERY OLD] (Completed) Honey Mustard Learning To Love Again by PinkHorsePro

Red has a goal. To get Flowey to UnderSwap. But when Blue comes crashing through the portal and has to stay in Underfell till it's fixed, it's hard to say what will happen to them. Yeah I know, not the best description but don't know how else to put it. This is mature rated and I suggest you read with caution. Also, Undertale, Underfell, Underswap and all the characters in it do not belong to me. They belong to their rightful owners. The Artwork doesn't belong to me either, it belongs to freshoutofparsnips on tumblr. This is not my first fanfic but it's the first one I've posted online, so please, if you have any advice for me I will gladly accept it.

Monster's Daughter (A Undertale Reader Insert) by SpiritWolfNura

You always knew you were different from the other kids. You knew things the others could never remember. Like how sometimes monsters were on the surface and they disappear just as quickly. You want to get down to the bottom of it and fall down. Ready to learn things you never knew about yourself?
