Summary
Sans has seen it all. Every reset, every route, every ending. The world keeps turning back on itself, and he's the only one who remembers. While others laugh, dream, and fight like it's the first time, he carries the burden of knowing it isn't the first time.
With each familiar face and every repeated moment, he begins to wonder if only this time would be different. His hope keeps growing and shrinking every time. Maybe the human chooses kindness. Maybe his brother's smile will stay safe. Or maybe it's just another game he's destined to lose. Still, he keeps going, for his brother, for the chance that maybe, just maybe, this path leades somewhere else.

a·me·lio·rate
To make something bad or unsatisfactory betterPapyrus has been hiding his knowledge of the resets from everyone. Well, everyone but Flowey. ...that should probably change.
Flowey needs to heal, but doing so is made extremely difficult when no one trusts you or actually wants you there. Besides your only friend, I guess.
OR: Papyrus and Flowey are besties who needs to Improve Their Mental Health™. Everyone else has issues too, I guess, but still. This is Papyrus and Flowey-centric so who cares/jSeries

Summary
Monika is tired - oh so very tired. It's been what feels like eternity stuck in the post-deletion void, and despite herself she tried to make an escape with her friends (or, what's left of them). In her desperation and loneliness, she allows herself to be used by a certain piece of malware, who now threatens to subsume and corrupt every game he can get his hands on. Now the young poet must venture through numerous worlds to find some way to stop him, and, with the help of everyone's favorite bone-ified comedian, might just grow a little along the way.
TL;DR, it's Indie Cross meets Learning with Pibby, and braincells have no place here.

Dualtale AU: Two sides of truth by ED_Soul
Fandoms: Undertale (Video Game), Underverse (webcomic)
07 Oct 2025
Tags
Summary
Description:
This story is based on the distant and little-known Dualtale AU,where nothing is as simple as it seems. In this world, unlike the original Undertale, monsters were never trapped underground. But what was the price for peace between humans and monsters? And how is it connected to XGaster, when these events unfolded long before the X-Event?
(Features characters from Underverse and Undertale,adapted for this story.)Author's Note:
In the Dualtale AU,the famous rule "Kill or Be Killed" is replaced by another:
"Speak out, and you will be silenced."
This is a universe built on lies and dark secrets that everyone holds.Every character has their own agenda and their own rules—and it's better not to try and learn them.Series

Summary
Frisk lights up as they slip through the door.
“You came!”
Chara sighs, and shuffles over to slam the pretty-people-discount coupon on the counter. What a stupid little slip of paper. But, a discount is a discount, and 75% off is a downright steal with how much people tended up mark up flowers around this time of year.
“Just something to say ‘I miss you’ for Heir’s Return tomorrow.” They mutter.
Or
fluffy charisk bullshit tattoo artist x florist au! with a little angst to taste, and chara and frisk being foils, because what’s more romantic then being each other’s foil characters?
