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.

[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.

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: ???

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.

Just something I wanted to do.

Once Upon A Story by AlexBrant18

We all know that story of the Destroyer and Creator, but for the sake of this story, let's say the Destroyer didn't like destroying Alternative Universes. Let's say they didn't like killing the innocent nor the murderous. Let's say he didn't like who they were nor what they did. For the sake of this story, let's say they made a wish and only had the lost hope of it coming true. Lets say they wished to be forgotten. Let's say it came true. But Fate interfered, and though they couldn't change it to they're liking, there were changes that did suffice them. However, let's say, it wasn't enough. It was too late to fix it though.
