Summary
Again. And Again.
Kris is suffering from the constant defeat being handed to them and their friend by The Angel's Heaven. So imagine their surprise when The Knight steals them all away into the Void as a last ditch effort.
And drops Kris into the Underground alone. Well, not exactly alone. They do have some kids (one human, the others ghostly) to guide through a new world where every monster they once knew is trying to take their souls to break a barrier holding them beneath the mountain, all so they can wage war against the humans above.
Welcome to the Underground, Kris. Enjoy your stay.Hello, everyone. This is my rewrite of a fic I stopped updating 6 years ago. Recently, I played through Undertale again with a mod I downloaded thanks to the Internet posting about it and a friend saying that they've been meaning to get around to it. It was fun, and got my writing brain to shake off the dust. So here we go, a rewrite of my most popular fic on here.

Summary
Oshima Island is cursed. Any ship or person who nears the island is never seen or heard from again. A rather perfect spot for an Octarian Outpost, says the Captain. And since Callie revealed that Octavio had sent a team there for a reason even she doesn't know, Agent 3 is sent there for a week to investigate and report back their findings on this Octarian threat, as well as possibly determine what's been happening to its past visitors.
The good news: Agent 3 figured out where the lost visitors may have gone.
The bad news: There's an entire testing facility under the island, and they've become another Test Subject in it.
Luckily, they have a bit of (Slight) help: An amnesiac Octarian Soldier named 10,008 was made their testing partner, and now if Agent 3 wants to escape before the week is up, they'll need to work with their own enemy, and hope to cod he doesn't backstab them once he regains his memories. -

Summary
A year after the last Prince of Subcon Forest died and The Snatcher was born, a red dot appeared on the moon.
And just as it had appeared out of nowhere, it disappeared several days later, only to return the next year. And the year after that.
A legend was born around the red spot on the moon, that when the Prince of Subcon breathed his final breath, he shed a drop of his blood upwards to the Moon and stained it. The denizens of Subcon honor the Blood Drop as a period of mourning for their fallen kingdom.
Today is the beginning of the Blood Drop's Mourning, and it's the Kid with the Hat's first time witnessing it. But a closer look at the red spot makes her reach out to the Snatcher. -

Summary
Because Deltarune isn't exactly complete, the first chapter is based off one of many endings I thought Deltarune would take. This idea has also been in my head for a while.
Kris and the Fun Gang have been unable to stop the Angel's Heaven from destroying the world and causing Kris to reload their save. Multiple times, actually. No matter what they did, it wasn't enough. The Angel's Heaven would always destroy them.
So what happens when The Knight (Gaster) drags The Fun Gang into the void and separates them in another universe.
One in which the Monsters were sent underground after a war with the humans.
Now traveling with a small, silent yet flirty child, Kris has to find their friends in a new environment, where everyone they once knew now wanting their soul.
Welcome to the Underground, Kris. Enjoy your stay.

Summary
In Deltarune's world, Chara and Frisk both run away from their 'homes' the same night. Unbeknownst from each other, they still arrive at the same little town.
Wounded, Chara has to be taken in. With nowhere else to go, Frisk is sent with them to stay with Toriel for the time being.
Kris is not too happy about this, especially since soon, everything will be set into motion. Two human kids, one acting out and the other curious to a concerning extent, will only make it harder for them. At least it can't get even more complicated.
...why is there a third one and why are they here ?? To... 'find the missing kid' ?
WHY ARE THEY STAYING OVER TOO.

Summary
Both Inklings and Octolings know of Inkopolis as a city of possibilities and beginnings, where the sun shines and music is played in every heart. Though their presence hasn't been made public knowledge yet, more and more Octolings are migrating to the City of Colors alongside young squids who want a piece of the dream for themselves.
But some find that the road to their dreams is much stormier than they anticipated.
Hook is a young Inkling boy from a small town who's hoping to make it big on the turf. Maya is an Octoling deserter who's fleeing from her past, trying to start a new life under the sky.
They, and many others, will have many obstacles to overcome before they can realize their dreams.
