Summary
"They’re sitting in a bed of golden flowers somewhere far beneath the earth, and, as far as they can tell, for better or for worse, they’re decidedly still alive."
_ _ _ _ _
Frisk climbs a mountain and inadvertently awakens an ancient terror sleeping beneath the flowerbed they land on when they fall. If by "ancient terror" one assumes the less-popular definition of "annoying narrator-ghost princet of monsterkind who is now, unfortunately, permanently stuck in their head."
Chara doesn't want to be awake. They especially don't want to be helpless in the back of a bloodthirsty human's head, watching them ruin the only home they've ever known with no power other than their voice to fight back with. Luckily for them, that's not what's happening at all. Unluckily for them, they may have to re-evaluate a few things about their worldview. Which, for someone as set in their ways as them, is not an easy thing to do.
(Then there's the matter of the weird flower, Frisk's unusual powers, and the Longest of Long Days the underground has ever seen.)Chara & Frisk no player AU true pacifist. Updates semiregularly from ~80 chapter backlog!

Summary
Honestly, Cherry didn't think that playing Undertale and reading an unhealthy amount of fanfiction was what lead her in this position. She wasn't happy at all. Because who the FUCK?! Would wish this upon someone? Sans the Skeleton, was a goofy character in a game, that was it. Nothing more, other than the fact that he has One HP and can still kick ass. But that was in a game. In reality? It was much scarier and alarms were blaring in her head. So yes, Fuck whoever brought her here, she didn't care. She just wanted to take a short nap. That was all.
(Hello! Somewhat new to fanfiction, this was inspired by so many great fanfiction, and once I can figure out how to put in the creators and their creation in this, I will. Thanks for reading, and if you don't want to that's also fine, please don't hate, and any healthy criticism is fine. I need assistance anyhow. Please don't rush me, I have a life like all of you, and I get lazy or burnt out at times. Thank you.)

Summary
After Sans' machine malfunctions, The Fun Gang and Noelle Holiday find themselves pulled into the events of the Glitchtale AU, where they prove to be invaluable allies against the evils that threaten the world and its people, human and monster alike.
However, by merely being present in the Glitchtale Universe, Noelle and the Fun Gang have unwittingly raised the stakes by a considerable amount, as breaches in the fabric of the space-time continum begin to appear, allowing humans, monsters, Lightners, and Darkners from their dimension and a myriad of others into the universe the quartet now find themselves in, including new allies that join the fight on the heroes' side, as well as newer, deadlier threats from all across time and space that, thanks to the breaches, now threaten the entire multiverse.
Can our heroes survive the coming storm? Or is all of time and space doomed to fall to darkness?
Let us begin the experiment and find out together, shall we?

Summary
Two people of completely different backgrounds and ways of existence die at the same time, in almost the exact same manner. Due to a grand, universal, mathematical error, they are now forced to live out their lives sharing a single consciousness and body. For the first time, someone is able to understand his speech. For the first time, someone is able to understand things from her perspective. Initially spiteful and overly bitter to one another, they grow attached to each other's company. What would happen if they die? How much does someone have to contribute to be deemed worthy of respect and understanding?
A commentary on loneliness and the plight of the foreigner.
A love letter to the fanfics I have read, connected with, and grown to love.

Summary
Meet Lily Morgan - A twenty-eight year old PTSD suffering and agoraphobic Undertale fangirl. After nearly a decade after the attack from her father, she's finally settled into a routine. Therapy, taking care of her cat, hanging out with her weeb loving best friend Megan, writing fanfics, drawing fanart, and collecting merchandise with what's left of her disability checks.
Life isn't great, but it's not terrible either. But when the Director of a group called PRISM hunts her down, her cautious routine is about to be thrown out the window.
Undertale is real. Well, more like all the monsters of Undertale, Underfell, and Underswap were pulled over during an accident involving dimensional travel experiments seven years ago. Nearly thirty-six thousand monsters reside in an underground facility, as well as the three human children, and now Lily is being offered the position of a lifetime.
Become something called an 'Overseer'.
With a shady government company, experimental 'augmentations', and nothing more than a fangirl determination to do better by monsterkind, Lily's read enough fanfiction to know this is a really fucking bad idea.
It doesn't stop her from signing the contract.

Summary
Basically all of my different Cocoapowder oneshots I've written since my other story I tried to write failed. I didn't really find enjoyment in anymore so I just started doing these oneshots instead. I hope it is good enough for the Copow community to stay fed!
Thanks for many of my friends for helping with the ideas/proof-reading of these stories! They were mostly written at 3am on a college exam night so I am very grateful. Also, shoutout to the r/Cocoapowder Discord server (which is now my home) for making all of this possible!

Summary
When Papyrus' daughters want something read to them that has princesses in it, Sans chooses the lazy way instead of coming up with a story. He types princess in the timeline machine and straight reads off a Princess Frisk adventure. After a couple of nights, Papyrus leaves and Sans is in charge of the girls. When he reaches the end of the princess adventure, he knows where Papyrus is at.
He also knows that their timeline is about to be erased, if he doesn't find his own version of Princess Frisk.
