Summary
Based kinda on thestrongestjewel’s eepytale on tumblr but with my own little spin on it.
In a world where monsters and humans talked it out and DIDNT go to war. Chara tries to just live their life with their very chaotic adoptive family. Their life was pretty solid until a new kid comes to Hometown and decides to mess with the norm.
(The story will primarily follow Clover and Chara with some silly side stories for Frisk, Asriel, and Kris)

Summary
Grillby doesn’t feel fear often.
But when he looked into the eyes of the chained merfolk at the circus, something inside him cracked.
He doesn’t know what to call this pull, this ache, or why his soul reacts like it does.
But he knows one thing: he can’t leave it there.
---------
Merfolk (The nearest Gender Neutral form of mermaid/merman)/GrillbyCan be read as Reader insert or as OC, the most of the story is from Grillbz POV.
Don't plan this as a long fic, got inspired by a merman art I saw.
(Can happen in the same world as my other Undertale fic with Reader/many skeletons)

Summary
In an alternate universe, D had a habit of breaking her soul apart to make new gods out of boredom and curiosity. And she eventually paid the price for it, dying as her soul fragmented apart for the final time. Of course Shiraori had to take on her job while her progeny gods worked to try and piece her back together so the universe doesn't collapse.
All while the humans of Shiro's world f#ck up a summoning and fuse their planet with 12 others, and other shit I'm not gonna mention here.

Crack au of some kind lol. While there is an overarching plot I'm probably gonna go off on stuff and make the chapters non linear not sure what to do here honestly.

Summary
before i really began writing this whole au, i had a very different idea. since the au has taken a completely different course, and this was written before much of emery's lore was developed, this is no longer 'canon' to the au. consider this another au of the au lol
i still really enjoy the bonds emery forms here, but with the way the real au is taking place, its going to be difficult to write them in the way i want
also i feel bad that i havent updated the actual au in a while, despite saying i had so many things written. everything written is non-canon now. the canon stuff is all in my head. i will get it out eventually, but you might not like it when i do. we're in for a bumpy ride
quite a lot of these were written almost 4 years ago and are incomplete

Summary
The Light World.
A world where humans & monsters coexist with each other.
Living in a functional society.
For most, all they have known was the light.
The blinding light.
The unchanging light.
The light that shines to hide away the darkness.
But, on a day that was supposed to be peaceful, an unknown entity hijacked all screens and signals in the world.
In which, it started broadcasting something else.
Something
Very
Very
Interesting.
A revelation...a way to let the darkness take a stage.
...And who could've guessed it would all start in a small little town?

Summary
Frisk, a child who previously gave up on living due to having a hard time on the surface, falls into the Ruins. After spending time in Toriel's care, they find the strength to go on. To them, this means they need to leave the Ruins. After facing their first death during a confrontation with Toriel, they address the elephant in the room (or rather, the extra human in their brain): Chara. Chara has no memories of their life and no motivations in particular, but as they get to know the other human kid that they're stuck with, they can't help but get attached. Frisk reminds them of themself, somehow, as if they were two sides of the same coin.
Together, they traverse The Underground in their now shared body, meeting foes, friends, and foes turned friends along the way. Despite having previously considered themselves good as dead (or actually dead in Chara's case,) they find their hearts crying out that they want to live, no matter what that ends up meaning to them.

Summary
The dichotomy between black and white is your constant when it's time for you to meet the whole new civilization Frisk brought along with them to the Surface.
As a parent, it's not easy to trust others when they've hurt your child.
So when that new civilization decides they owe Frisk both for saving their kind and for still hurting them during that process, you've got plenty to say to them.
Forgive as easily as you once did with others during a stage of naivety? Oh, hell no.
They better have a good reason for hurting your child and an even better one for wanting to be a part of their family.

Summary
You never thought you would move to New Ebott, but after learning more than you should have, it was the only city where you could hide it.
It was the city where monsters and humans lived side by side, where both could be mobsters, thieves, dealers, or saints. Sometimes all in the same breath. New Ebott didn’t ask questions, though. It didn’t care who you were, just what you brought to the table, or what you could pay to keep off of it.
Of course, you had plans to stay out of trouble. That was until you met a golden tooth skeleton who won't leave you alone.

Summary
A hundred and five years ago, a person calling themself Chara became the first human to fall into the underground. They would go on to become the closest of friends with Asriel Dreemurr, the prince of the monsters. Both of their deaths, four years later, would go on to shatter the underground irreversibly.
The year is 2124. A person naming themself Frisk climbs Mount Ebott in a desperate rush and, voluntarily, becomes yet another victim of the mountain. Not long after, they soon come into contact with a strange, traumatized, and frustratingly cute spirit that they come to call "Red." Clearly, they are not okay, but what exactly is weighing them down vexes Frisk. Though, they have their own demons to contend with that they struggle to seal away.
They wander through the underground, learning more about each other, helping each other with the mental wounds and scars each have yet to tend to. And maybe, just maybe, they might tell each other how they have come to feel about one another.

This is just going to be a dumping ground for all the fandom related art I do. Some might be of fanfics, others may just be an AU of my own creation. I might do requests in the future.
