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.

Summary
To protect your secrets, how far are you willing to go?
This is the dilemma that Papyrus, the royal guard's captain of Snowdin town is facing since he accepted to protect the last fallen child. What he thought would be a simple task is slowly driving him away from his guard's duty, at the worst time possible.
When he finally understands something is really wrong with Undyne, his rival and only friend, it's too late. Overnight, the general announces to him that he is now in charge of the royal guard and disappears from his life.
Even if he tried, Papyrus couldn't resolve himself to let her go without knowing why she gave up on everything in one night. However, by trying to dig out too many secrets, Papyrus has to face a lot of problems. Threats, intimidation, someone is trying to force him to give up.
But the more he searches, the more he realizes all the tracks lead to Asgore. The King is known for his impeccable justice and his absence of mercy. If he doesn't give up, he might lose way more than just his job.
Split between his vocation and his friendship, Papyrus will have to make a choice.

Summary
You were always so warm.
Too bad you didn't exist.
+ + +
Living in Snowdin could be rough. With his nagging younger brother, the 'kill or be killed' mentality, and the human runt who kept coming around to release them from the Underground, just to throw them back in again because something was missing - he was tired. Exhausted even.
So, when he starts dreaming of a lover - someone to hold - someone soft and warm and humorous, he starts losing his typical edge. Even though you're just a dream, he's keenly aware that there are somethings that no one's taught him before... but you have.
Papyrus has started to notice something's... off. And so has Frisk.

“Ya know… I didn’t think that when the kid mentioned an older sister that it’d be you, sweetheart.”
“Weird… Isn’t it? I-I didn’t think that I’d be seeing you again. N-Not that that’s a bad thing! I just… who would have thought that we’d be neighbors or that you knew Frisk? But thinking about it now, it makes sense that you would know them.”

Summary
Fills for a list of prompts for Loveuary 2025, a soft love focused month long creative exercise posted on tumblr. These will be varied in content and explore different types and expressions of love. This will be Papship centric for the most part, but some chapters will include non-romantic relationships as well. I really want to motivate myself to complete this challenge, so here's to hoping I can.
First chapter will be informational, but first story should be posted shortly there after. -
How to Protect a Human from A Murderous Fish by Floofanflur

Summary
STEP ONE: TELL A VERY CONVINCING LIE ABOUT THE HUMAN'S NON-EXISTENT PRESENCE.
STEP TWO: BE CAUGHT IN YOUR LIE AND PREPARE FOR YOUR IMMINENT DOOM.
STEP THREE: …LIE AGAIN?
STEP FOUR: WHAT THE- HOW DID THAT WORK?!Papyrus had a very thought out and well prepared plan for making sure Undyne didn't kill Frisk—until Undyne went off script and showed up at his house. That was okay, though. Papyrus was nothing if not great at thinking on his feet!

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.

Tales From the Multiverse: Origins by xXSodapopFrequenceeeXx
Fandoms: Undertale (Video Game)

Summary
After the war with the monsters, all demi-humans, including werewolves, vampires, and shape-shifters have been banned from the surface to protect the humans that remain. Any found will either be executed or tossed into the gaping hole of Mt. Ebott, never to return. Anyone who turns them in will be handsomely rewarded, even if the demi-human in question isn't actively causing harm.
All she ever did was try and protect herself. All she wanted was to stay safe. However, human laws are deaf to monster pleas. Luckily, eighteen-year-old Delilah got the more merciful option, finding herself exiled into the underground. However, down there, it's survival of the fittest. A life lead that way is one the demi-human has never known. Instead, it's been lived trying to conform for the sake of her own survival. Now, Delilah must survive an unforgiving world where it's kill or be killed. If she fails, she will die before she ever sees the surface again. The question is, does she have what it takes?

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.)

Summary
In a world where monsters have a taste for violence, the underground has become a wretched place to call home. Although outposts of peace and civility exist, the lands between places such as the RUINS and SNOWDIN are dangerous. Crime often leaks into the towns and cities, and monsters have even begun killing each other for food, shelter, or even as a result of losing all hope they will ever escape their prison. 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...

As it says, Frisk meets other protags. Takes place in the same story setting as "Asgore's Adventure". I wrote a really dark joke at the end but took it out.
