Summary
First chapter is pretty unserious, once the rest are made you could probably like skip first chapter ngl it’s not that important I think
ok I lied it’s kinda important
anyways basically clover in the pacifist route gives their soul up and wakes up in a void, wing gaster decides to remake Deltarune to help them have something to do while they are stuck as a soul in the Undertale world. Except you can’t just copy and paste a soul! Well, Gaster can’t. So there’s a few minor errors! (That don’t appear in chapter one.)

Summary
After Basil’s death, Sunny runs towards his home in an attempt to end it all, but Aubrey follows him and she prevents him from dying. Sunny tells her the truth and now they have to face it together.
After moving, they find themselves camping until something happens and now the two will travel together in order to escape the Underground filled with creatures that were only believable to see in fantasy books.Notes:
the Undertale tags are there because I want to make an Omori x Undertale fanfic, but there won't be anything related to Undertale during the first two chapters except for some references to Mt. Ebott and its legend, but around Chapter 3 or 4 onward, the Journey through the underground will begin!
So stay PATIENT!Series

Summary
Clover is dead.
And yet, he persists.
Unable to let himself fall into the unknown that is death, his soul clings to a facsimile of life, trapped in darkness with nothing but his thoughts and time to reflect and ponder. He will not, cannot move on, even when there is nothing left for him in this world. No body, and no hope of returning home. No hope of reuniting with his friends.
Until someone called for help.
Now stuck in an Underground he does not recognize with only his trusty four-shooter and a friend he can’t trust, Clover searches for his friends, the voice who called for help, and answers. Retracing his path through the Underground, and forging a few new ones as well, Clover battles his thoughts, suspicions, and memories of events that never occurred, but won’t quite leave him either.
Now, if only he could find his hat.

Summary
Frisk has once again fallen into the underground! However, something wasn't right. Memories kept eluding them as they traveled. The feeling of being watched never leaving them.

They only want to leave to get back to their sister. They had to before it's too late. But after interacting with a few individuals, there was something else they had to do...but would they be able to help?

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
(Immediately after the events of Deltarune Ch 4) Follow Kris, Susie, and Ralsei into the Dark World once more as Kris struggles with their autonomy, especially with their growing relationship with Susie and how much they wish their friends knew the real Kris Dreemurr- and not the SOUL. I hope reading this story makes you feel like you're playing the game. I'll be the first to tell you, I'm not as smart or creative as Toby Fox, but I'm doing my best to write all the moving pieces of this Dark World of mine. What suffering awaits the Fun Gang?

Frisk's genocide has almost been completed. Sans, Asgore, everyone; reduced to dust. However, there's one more opponent Frisk failed to anticipate; a foe even tougher than a true heroin or comedian. Across from Frisk stands a gunslinger who is the dictionary definition of justified! And their name… is Clover.

Summary
𝗦𝗲𝗾𝘂𝗲𝗹 𝘁𝗼 𝗣𝗲𝗿𝗶𝘀𝗵.
𝙐𝙣𝙙𝙚𝙧𝙛𝙚𝙡𝙡 𝘼𝙐---
In a world where everything seems to be slipping through his fingers, Sans knows that the only way to survive is to do whatever it takes. With the weight of her life in his hands, he faces a terrifying truth: some things are worth losing, but he’ll do anything to ensure she isn’t one of them. In the end, the question isn’t just how far he’ll go—it’s whether he can live with the cost.
---
He remembered the conversations and the words they’d already spoken a thousand times over, the responses they’d known before they’d even asked. He remembered the fights and the endless, grueling battles where he had lost, and then won, and then lost again. The victories became hollow, empty echoes, and in the end, even the victories felt like failures.“You ever wonder,” Flowey’s voice trailed off, dropping into a hushed murmur that seemed to blend with the sound of water lapping at the stone. “If maybe she was never supposed to come back?”
The question hung in the air, heavy and unresolved. Neither of them spoke after that. They just sat there in the swamp, a place that used to be full of life, now lost to time and decay for what seemed like ages.

Summary
My version of Flowerfell. Frisk, Chara, and Flowey are the main focus because I think this friendship has a (skele) ton of potential that's sometimes overlooked.
I will not be shipping Frisk, Chara, or Flowey with anybody, including each other. In this story, Frisk is seven, Chara is thirteen, and Asriel/Flowey is twelve. I will include a few scenes of Sans x Grillby, and I may include Papyrus x Mettaton, but I'm not sure.
There will be angst, and a closer look at how Frisk's health would be affected by buttercups growing out of their skin. If you don't know what that would entail, please do research before reading. Saying that it isn't pretty would be an understatement.
There will be fluff and fun and shenanigans, it isn't JUST angst.
Edit: I decided to add in an original character. Boom. -

(Y/N) had been in the underground for around a year now, she had done her best to keep herself hidden from the bloodthirsty monsters who sought her out for her valuable soul. She had grown accustomed to living in her small cottage deep in the wood outside of Snowdin in total isolation. She figured it better than daring to tread past the treeline and soon 𝙥𝙚𝙧𝙞𝙨𝙝.

"It's your funeral, doll. Harbouring someone like me ain't in your best interest." Sans said with a deep chuckle and a shrug of his shoulders. (Y/N) understood the truth in his words, she knew fully well what he was capable of and that allowing him to stay until he was strong enough was going to be her death sentence.(Y/N) didn't understand why she didn't just use the last flare in her gun and get rid of the problem. But, the thought of pulling the trigger brought a wave of nausea over her. She refused to become like the other monsters of the Underground, all clawing and fighting like vicious animals for the title of most feared.
