Summary
Their King is dead. The six Souls are Gone. Their future lays in ruin.
Frisk has slipped through the barrier and left the monsters with shattered hopes and a toppled monarchy. With no witnesses, it was pure, selfish regicide. They were loved by all, and thus, their betrayal cut all the deeper. For the third and final time, humans had stolen everything from them.
Anger has a way of changing people. It remains in the Soul even as memories fade.
Frisk may be gone, but the RESETS continue, multiplying the resentment within them and morphing the residents of the Underground into tightly wound reflections of their former selves. No longer in a position to do nothing, Sans is Determined to find a way past the barrier for the sake of his brother, and for the sake of justice.
He’ll give anything to achieve that goal. His Soul included.
He’d found an alternate method that should work, buried deep inside a gilded dusty tome in the royal library. Instead of using LoVe to pass through the barrier, Sans was going to use love. He was going to have to gain a consenting human, and convince her to bind her Soul to his. Permanently.

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. -
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

Summary
Deltarune, but the dark worlds are a little different.
A crossover of TMA and Deltarune, where rather than darkness, then fountains are made of fear. I'm not writing 14+ entire Deltarune chapters so don't get your hopes up if you really like the vast, slaughter, flesh, or hunt. I might mention them though.
Babys first writing ever, be nice okay. you can still make suggestions or point out grammatical errors though

Summary
Papyrus hadn't been worried! ...Well. Maybe he had been, just a bit.
It'd been a while since anyone had heard from the human, so he called to check on them. But when a conversation revealed just how young they were, he realized things had to change. They were all on their own down here. And... They had nowhere to go.
Well! If there was no one else to take care of the baby bones, Papyrus would just have to do it himself!
—
Sans was trying to get through life and ignore the apathy that had settled over him for Papyrus’s sake. It was just so hard to care about anything when he knew none of it mattered. But when Papyrus had him bring the anomaly home like a lost puppy, things stopped adding up.
How could such a sweet kid be responsible for the relentless time loops?
—
Frisk was used to being on their own, and they were pretty good at taking care of themself. But—Well. ...Dying hurt. They just wanted to get back to the surface! With Undyne in the way, they were hopeless.
So when a phone call from Papyrus somehow ended with an offer for them to crash at his house, Frisk could only be relieved for the break.
They could afford to rest for a while, right?

Summary
Two souls in the Underground, intertwined by fate and by a prophecy that keeps them apart.
Heads up before you read:
In this fic, Chara is alive and far from a good person. They’re not a mindless killer, but a narcissistic kid. This is not a fluffy Charisk story. Chara and Frisk’s relationship is deeply toxic.Please look at the tags before you continue.
I've been experimenting with third person for a while now, and I've grown to like it a lot more than first person. For those who came from my other fic, which I promised a sequel for, I’ll try my best, but I’m not sure how that will go now that I’ve fallen in love with third person and started a new long fic. Please don’t be angry I will try to finish my other fic as well.
