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
We're back with another year of Inkwhumptobertale!
And this year, we have another twist: another list! That's right: every day, I'll be facing the challenge of eight different unrelated prompts, and I'll have to do my best to cram them all into the story, somehow. Admittedly, there is a low chance of me actually doing that, but I am obligated to use at least three prompts each day, and I'll add more if possible. I'd like to do at least one day fitting all eight prompts into the story at some point in the month, though. So..prepare for chaos!
These characters are not mine!

Summary
“Stop messing around. We’re supposed to be keeping watch.” Cross huffed, turning to face XChara fully.
XChara glared at the snow when Cross said that. He reached down and scooped up some snow into his hand.
XChara ignored Cross’s attempts to get him to lock in. “Why do I even try…” Cross rolled his eye lights and turned back to face the crowd of people, but was hit by something cold and hard on the side of his skull.
“BAHAHHAHAHA!” XChara was rolling on the ground clutching his stomach from laughing as he watched the snow slide down Cross’s cheek.
-----
Cross and XChara find themselves stuck in the middle of an ongoing Multiverse war as they where sold off to Nightmares gang for his super secret evil plan----
first time writing fan fiction, kinda nervous

Summary
You'd never expected to be one of those people who bonded with a random stray, and if you did, you never expected it to turn out like this. The tiny... blob of an animal was cute, affectionate, and melted your heart before you'd even named him. Unfortunately, not everything is as it seems. You've met this lovely creature before, and he definitely remembers you...

Your purpose here? Maid. At least, that’s what they say. But there’s more to this dark, twisted world than simple tasks. The figures watching you from the shadows have their own plans, and you're nothing more than a pawn in their game.
