𝗦𝗲𝗾𝘂𝗲𝗹 𝘁𝗼 𝗣𝗲𝗿𝗶𝘀𝗵.
𝙐𝙣𝙙𝙚𝙧𝙛𝙚𝙡𝙡 𝘼𝙐---
In a world where everything seems to be slipping through his fingers, Sans knows that the only way to survive is to do whatever it takes. With the weight of her life in his hands, he faces a terrifying truth: some things are worth losing, but he’ll do anything to ensure she isn’t one of them. In the end, the question isn’t just how far he’ll go—it’s whether he can live with the cost.
---
He remembered the conversations and the words they’d already spoken a thousand times over, the responses they’d known before they’d even asked. He remembered the fights and the endless, grueling battles where he had lost, and then won, and then lost again. The victories became hollow, empty echoes, and in the end, even the victories felt like failures.“You ever wonder,” Flowey’s voice trailed off, dropping into a hushed murmur that seemed to blend with the sound of water lapping at the stone. “If maybe she was never supposed to come back?”
The question hung in the air, heavy and unresolved. Neither of them spoke after that. They just sat there in the swamp, a place that used to be full of life, now lost to time and decay for what seemed like ages.

Summary

---
(Y/N) had been in the underground for around a year now, she had done her best to keep herself hidden from the bloodthirsty monsters who sought her out for her valuable soul. She had grown accustomed to living in her small cottage deep in the wood outside of Snowdin in total isolation. She figured it better than daring to tread past the treeline and soon 𝙥𝙚𝙧𝙞𝙨𝙝.

"It's your funeral, doll. Harbouring someone like me ain't in your best interest." Sans said with a deep chuckle and a shrug of his shoulders. (Y/N) understood the truth in his words, she knew fully well what he was capable of and that allowing him to stay until he was strong enough was going to be her death sentence.(Y/N) didn't understand why she didn't just use the last flare in her gun and get rid of the problem. But, the thought of pulling the trigger brought a wave of nausea over her. She refused to become like the other monsters of the Underground, all clawing and fighting like vicious animals for the title of most feared.

Summary
It was hard to explain, exactly.
A feeling. Walking into his room and his clothes not being where he left them, the bed messy and unmade. His favorite seat having a new indent in it. Mostly-empty bottles of condiments in the fridge, a spare pair of shoes by the doorway. A glimpse of bone as he walked up the stairs. His brother talking about things that Sans didn’t remember. Hearing people use his name for someone else.
A ghost living in their house.

Fandoms: Undertale (Video Game), Underfell - Fandom
30 Mar 2025
Tags
Summary
Shylee watches her friends and soulmates, Sans and Papyrus, fall in love and eventually date her childhood friend, Mercy. The worst part is that they knew about the soulmate link with her, but they rejected it and demand her to do the same if she valves their friendship. She was heartbroken but agreed, believing their friendship was more important. Although she secretly hopes that it can still be more... But what would happen if she met two of her skeletal friends' cousins clad in black and red, and they offered her companionship?

Summary
Where Frisk was supposed to appear, it was instead Sans. Where buttercups were supposed to grow in the gardens of the Underground, was instead found in Sans' body. And a special someone somehow found enough hope to perhaps save him.
And yet despite everything, would that be enough?
TLDR: a Flowerfell AU, but instead of Frisk, it is Sans in their place.

How to protect a kid and their flower friend: a written guide by Blo0p

Summary
Tessa is a teenager just trying a to get by in an underground of danger, death, and betrayal. While she doesn't know exactly how long she's been down here, as the underground only has out-of-date calendars and no clocks, she knows she's fully adapted to her environment. She's even found a semblance of peace with her life as it is, oddly enough.
Then, another human fell. Terrified of the new world they'd fallen into (literally), but determined to get to King Asgore, Tessa finds herself acting as their big sibling in the kid's adventure; and she sure as hell isn't gonna let this kid, or their wimpy flower, die under her care.

Summary
**ON HIATUS**
"Not one human that falls down Mt. Ebott comes back."
But you did... though not unscathed.
After succumbing for the first time to the wrath of Toriel, you wake up to the sensation of something growing on you. A golden flower trails the contours of your face, right where the goat dug her claws into you. While gazing at your reflection, your fingers follow the tendrils of its roots carefully. A display of your untimely death staring back at you, yet you were here anyway.
A cryptic buttercup by the name of Flowey guides you through the catacombs of the Underground, latching onto you like glue in hopes to also escape. As you travel through the caverns, you realize that teaching the monsters mercy may be harder than you initially thought. Despite this, you're not one to give up so easily. Forming an alliance with a certain skeleton turns out to be the best mistake you've ever made.
**flowerfell does NOT belong to me! this is just my take on the story since i found it very intriguing.**

Summary
Frisk has reached the end of the road in their resets and the strain of their timeline finally gives way right before they can fight with Sans.
In a last minute feeling of regret, they try something unbelievable.
They relinquish their soul, and the next thing Sans knows he's laying in a bed of flowers, feeling like he was ripped apart atom by atom and then put back together again.
Also he has hair.
And skin.
And this new Underground he's ended up in isn't quite as friendly as he remembered. Great.

Courage [The Fanfiction that is Stuck in my Head] by Coffee_Carno
Fandoms: Undertale (Video Game), Original Work, Underfell - Fandom

Summary
The streets are rough this time around in Ebbot. Winter has never been easy. However, this year, just looking for food or asking for spare change became a lot more difficult. There was already snow on the ground before halloween even came around the corner. It was going to be a white Christmas for sure.
Although. You don't think you will get to see it.
Your body was running on fumes. And you knew it. You could barely walk down the alley to get to you make shift home in that abandoned building. You face plant onto the frosty ground. Too tired to try and get back up again.
Your brain was pounding against your skull. A silent threat of smashing it in order to touch the cold snow on your face. You move your face up, ever so slightly to breathe the air. God it hurt your lungs. The winter air, snapping the back of your throat with a scratchy feeling. Before, death was welcoming, however; Not now. You did not want to go back Underground to face Sans in that hall.
Not again.
So you did the one thing, you never thought you would do.
You call for help.
...
....
......
Someone heard your cry.

A Storm's Brewing Somewhere by handsonwelch

Summary
For the longest time, I've been the biggest fan of Underfell since I've discovered its existence. I also know it gets a lot of flak for being unapologetically edgy, which I understand. As such, I decided to put my own spin the universe as a whole, and recreate one of my favorite scenes from base Undertale in the process. While my depiction of the fell-ified characters may not be super good, I wanted to do them the best justice to their canon counterparts while also keeping that unique charm that Underfell gave them.
I hope you people enjoy it :) Maybe if I feel like it, I might expand on this more.
(And thanks to my friend Brycen for giving me the idea, and encouraging me to get out of my writing block for it. You really mean a lot to me, more than you know.)

In a world where monsters have a taste for violence, the underground has become a wretched place to call home.

A child has fallen down, filled with HOPES and DREAMS to befriend these monsters. A certain flower has decided its worth his time to assist them...

Summary
It was supposed to be a normal hike for Celeste. The birds were singing, the flowers were blooming. On days like this, she loved to go outside.
Except things quickly turn upside down.I feel like I've seen this concept before with Underfell but can't remember which fic. If I find it I will put this as being inspired by it.)
