Summary
Sans, in accumulated rage from all the tests, pushes Gaster off a platform in the core. Rather than in the original Handplates, Gaster falls onto another platform, dying almost instantly. Betrayal between brothers, angst, sadness, and possibly a crack in a seemingly unbreakable bond to follow. (If I finish this) the brothers will begin to learn about their mysterious captor and who he was, after he was gone.
This work has gotten many good beta read critiques, and may someday be finished.- Language:

Summary
Frisk and Leo (the Bravery SOUL human) have been friends forever, since they were babies. Now, the two 10-year-old children are drunk, chubby and currently at the bottom of a mountain in an underground civilization of monsters...but a True Reset says that this will be a first for both of them, so it's up to two drunk kids to guide themselves back home - without dying, that is.

Summary
Long ago, deep in the quiet woods of the Underground, Grillby sought only solitude. He never expected to find a fallen human woman-wounded, frightened, and far from home. Against his better judgment, he took her in. At first, it was duty that kept her hidden and safe from the Royal Guard. But when her laughter began to fill the spaces between his silences, protection became something deeper.
When word of her existence spread, Grillby made a dangerous choice: he marked her under his protection, binding her fate to his flame. Their bond grew-slowly, tenderly-but like the flowers she loved, her life bloomed briefly. And then it ended, leaving only memories and ash.
Centuries later, on the Surface, Grillby runs a quiet bar and tells himself he’s content. That is, until a new regular walks through the door - a woman with the same gentle voice, the same curious eyes. There’s something achingly familiar about her, like a dream half-remembered. His flame stirs, warmer than it’s been in ages.
But can love reignite across lifetimes? -

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.

Dualtale AU: Two sides of truth by ED_Soul
Fandoms: Undertale (Video Game), Underverse (webcomic)
25 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
Years pass. People grow. The world moves on without you. The Angel grew content with that for a while. It still hurt whenever they thought of the world that had long banished them, but something new pulled them out of the depths. Now, the Angel walks amongst friends who swear that they will not be banished. Kris, Susie, and Ralsei mean everything to them. Maybe this time, their banishment doesn't have to be as set in stone as they thought.
The Roaring comes. The light falters. Everyone falls.
A desperate connection is established in an attempt to save what remains of the Angel. If they fall, all hope will be lost. The world that banished the Angel long ago has forgotten them, but they have not forgotten it. This connection will have to be enough. Even if the rules have changed irrevocably, the Angel's one goal remains the same: Find them.

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.
