Summary
There are infinite opportunities in this world. Infinite opportunities for dreams. Infinite opportunities for hopes. Infinite opportunities for regrets... for loss.
There are some memories you would rather just forget...
The old royal scientist knew that better than anyone.
BRIGHT, BRIGHTER, YET BRIGHTER. SO YOU STILL SHINE ON, EVEN AFTER EVERYTHING YOU ENDURED. EVEN THROUGH THE COLDEST NIGHT.
But a story doesn't have to end the same way.
EXCELLENT. TRULY, EXCELLENT. LET US BEGIN THE CREATION OF OUR NEW FUTURE.
Sometimes... a game can have a secret ending.
(A Deltarune novelization that takes some unexpected turns from canon. Based on some theories, and a little bit of imagination, even the unknown can make itself known.)
(Custom Art and beta'd by Primordial_Rebel_Jester. Story by FoundUser.)

Summary
Your closest friend on campus is an Omega named Papyrus you met at orientation. He would be your best friend if it wasn't for a complication that came with being Papyrus's friend. His older brother, the Alpha Sans, who seemed like he was always ready with a threat or an uncomfortable observation.

Summary
A little bird flies the coop, clipped wings longing to soar, if only until she hits the ground.
Can she pick up the pieces her shattered heart and relearn how to live?Just, pure self-indulgence, really. Expect lots of fluff and shenanaganery.
My own spin on post-pacifist timeline. The monsters are free, but confined to one city, and kept secret from the world. A social experiment is run to see how humans hold up under long term magic exposure and if coexistence is really possible.
Our character, Robin, accidentally gets involved, and discovers a lot more than just magic as her life becomes increasingly intertwined with the lives of monsters of Mountainside. -

Summary
You're on the surface. Your family loves you. Everyone loves you. But they don't know. They don't know that you are a monster. Not the good kind of monster, pure, made of good emotions and happy thoughts. But a monster. A horrible, horrible beast.

Summary
Error had seen plenty of episodes of Undernovela and whole seasons of Romancetale where they’d talk about having partners and going on dates, and considering how his and Ink's friendship was progressing and the unfamiliar feelings Error couldn’t quite place, he thought that a date was the next step.
It’d taken him weeks to figure out where to take Ink, but eventually the pier seemed like the best idea. It was a common place, one where they could eat nice food and do activities, and from the movies he’d seen, it was a popular place to go.

The Sacrificial Skeleton and the Labyrinth of Gods by this_is_my_alt
Fandoms: Undertale (Video Game)
28 Sep 2025
Tags
Summary
As a necromancer, you’re used to suspicious stares and whispers of heresy from the townsfolk. It only gets worse after you’re killed and walk Ebott Empire as an undead skeleton. When you hear rumors of a strange settlement that worships the undead, it’s too tempting to resist. The locals treat you better than you’ve ever been treated. That is, right until the moment where you’re dressed up and tied to an altar as a sacrificial bride for their skeleton gods.
Despite their advanced technology and magical prowess, you’re doubtful of their divinity. What kind of gods blush whenever they see a bit of bone?

Summary
The Barrier's broken and the monsters are stepping out into a Surface they've dreamed of for years uncountable and forgotten. The human that helped them break through is at their side, just as unfamiliar and unsure about the Surface as they are. Upon first glance, the monsters stumble upon another human as they emerge from their prison. A human like any other, but to the monsters 'any other' human has been instrumental to regaining their footing on the Surface. Will this one be too? And are blushed cheeks something every human wears on the Surface? Come along on a journey with humans trying to understand magic, and the memories that follow. Following not as candles that warm, but as shadows that haunt. The human condition changes ever so much when exposed to magic, but how much? And how much can one human take before becoming determined?
A smorgasbord of events from tidying up a goat family to magic of the soul!

Dualtale AU: Two sides of truth by ED_Soul
Fandoms: Undertale (Video Game), Underverse (webcomic)
28 Sep 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

Where All Beautiful Days Begin / Blue Archive X Undertale Fanfic by ark1ved
Fandoms: Blue Archive (Video Game), Undertale (Video Game)
28 Sep 2025

Summary
Also on Wattpad!
Hundreds upon hundreds of genocide in the underground have passed, yet not a single soul could remember them. It was a cycle of awakening, dying, forgetting and repeat.
And the culprit was none other than that child, at least on the surface.
Occasionally, there would be a few differences between each reset. Once, two other judges were transported into the skeleton's world to fight the kid. Another, Sans went on a murderous rampage of his own to get stronger and defeat the kid. None worked out in their favour, however; the kid's determination always brought them back to life after death. It would always end in a reset of both the world and their memories.
However, this time, it was different.
Sans didn't wake up in his bed. Instead, he found himself awakening in what seemed like an endless canvas of sand.
Not only that, but it seemed all his memories from past timelines have returned to him.
*just what is going on right now...

Apathy's a Tragedy (And Boredom is a Crime) by Amy_Mask8119
Fandoms: Undertale (Video Game)
28 Sep 2025
Tags
Summary
Sans is an ordinary guy living an ordinary life. He may be the laziest pun-lover ever exist, sure, but there's nothing unusual about him. Average grades with no standout subjects and a dull, repetitive jobs shaped a fixed routine of wake up(late), eat, work, eat and sleep. Even birthdays blurred into the same numb monotony when you celebrate it every year.
Maybe that's why, when Alphys, the royal scientist of monsterkind, made a major breakthrough in alternate universes, He was one of the first in line to explore them.
Because surely, meeting new people will be enough to satisfy his boredom, right?
But alas, new people are still just people. And the more you know em, the less exciting they become.
Too bad that boredom is a crime that he'll do absolutely anything to avoid committing.
So when he stumbled upon a clash between the Bad Sanses and the Star Sanses, instead of running away, he found himself a nice, safe spot at a distance to sit back and watch.
He never expected to get caught.
He definitely never expected to get dragged into the center of it all.- Language:

Summary
Sometimes life throws you a curveball. For you, your curveball was going to bed looking like a human, and waking up looking like a monster.
A skeleton monster to be precise.
With the barrier breaking, a large surge of magic descended on the town you live in, and transformed you overnight. Unsure what to do with you, and the others changed, you're ushered into a facility until a monster with similar magic can take you to teach you how to wield the now uncontrollable magic you've been given. After waiting in this place for four years, you'd given up hope that anyone would ever want to take you.
What a surprise for you when you find out that someone does. A lot of someones.
