Summary
Wake up buried in snow, alone, and with no memories?
Check.
Kepp seeingg numbers, words, and text floating around every object and surface as far as the eye can see?
Also check.
Why does every person he meets say he needs help?!
His perfectly fine if you ask him."I wonder what determination taste like"
Note from the author:
This is my take on Fatal Error—a much more none canon, this isbt even OOC this is just straight up diffrent person with the same name, amnisiec version of him.
He’s also not fully canon-compliant in terms of power scaling and has and maybe different origin and personality.
It’s my reimagining of him.
Glitchy, lonely, and filled with questions, bad puns, power to blow up annoying people and some more puns. -

Summary
How many runs has it been?
Not even Chara could count them. Over and over again, they saw the Human kill those they had cherished when they were alive. They had wished to do something about it, and had even suggested to the Human to pick another route only to be in vain. However, when an intervention comes from the Man who Speaks in Hands, they are given an opportunity to give one being the memories of the previous routes.
Garden of LOVE(Level of ViolencE) is a three part series and take on the already popular concept of Dusttale. In the series, Sans's memories are given back to him by Chara who aims to stop the Human's genocide routes.

Summary
Sunny ran out of his home due to a certain accident
He didn't intend for things to come to this
He ran to the lake, but because it was pitch black outside, he got lost in the woods only to end up on the cliff inside a mountain.
He was still thinking it was a nightmare so he jumped so he could wake up in the arms of Mari calming him down like any bad realistic dream
He always had
Unfortunately, it was the beginning of his worst nightmaresBtw English is not my first language
I should clear that out again after ehshttps://discord.gg/eKR9u7NvM

Summary
Clover remembers.
After spending quite some time dead, He finds himself with memories he'd rather not have.
Memories that tell him who he truly is.
Memories that haunt him.
edit: lowkey put me on the stuff I was on when I wrote this summary.
Anyway, basically Clover remembers resets, especially genocides. So he basically remembers how to use his powers from previous runs as well, and then la tee doo dee dum, and bam. Justice Evolved.
If you're curious enough to have questions, maybe read the fic. It'll boost my ego. (please)
(edit) Disclaimer: if you want to read for cocoapowder, cocoapowder chapters will be released at a later date. As of this edit, the relationship between Clover and Chara has yet to be explored.
------------------------------This work will contain Original characters for the sake of worldbuilding, and I fully intend to make some of them play major roles in the story.
This is an alternate universe to Undertale Red and Yellow.
This work will be from Clover's POV. (written in first person, not second person, aka "I" instead of "You") -

Summary
Gonna try my hand at this for the first time! These will all be Sans/ Reader, but might play around with various AU's I don't normally mess with.
Might also sneak some canon or not canon scenes in here from my fics if they fit hehehe.
Also going to try to do some of these with Gender Neutral readers, which I am not very good at but gonna get some practice in! GN Reader will stand for Gender Neutral reader.

Summary
A long time ago... humans and monsters lived in harmony. Until war broke between the two races.
The humans were victorious and sealed monsterkind deep underground with a powerful spell, that could only be broken with the power of seven human souls.
This was the tale of Mt. Ebott, and the tale trascended into legend. Those who climbed the mountain, weren't seen again.
And so, begins the tale of the fifth human soul to fall into the land of legend, to fall... into the Underground.
This is the tale of the Purple Soul... Sunny Suzuki.

A contribution of oneshots for an Undertale Yellow AU from UTY Sub-Reddit called "Mamadillo" made by u/CandidCriticism1730
To put it simply, at one point Dina (The Wild East's Saloon Owner) adopts Clover. That's it, and I love it to the bottom of my heart.
And here I am, making a chapter whenever I can to contribute more fluffiness, or angstfest :V

Summary
As you walked you failed to hear the screams of terror of a bus going over 100 miles per hour and the sounds of it starting to bust down- it speeds near the sidewalk—the people in it shriek. Their blood curling screams didn’t occur to you, your headphone quality being way too good. Your shoulders relaxed as you stretched your limbs; very much unaware of the danger and pain that would very much make your life way more miserable. You should move out the way. But- likewise, you are unaware. Of death flickering and time excited to cut your strings.
The bus is almost out of energy- and has been stopped.
Or so people thought.
It began to tilt- right where you were very much slowly walking. Andddddddddd—
It didn’t crush you to death.
