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!

Summary
This is a undertale au made by 💖ME~💖! It’s called Tiredtale. I was inspired to make this after finding out about a dead au called FlowerFell that I’m actually pretty mad about not being able to read it. Fuck you, you damn Frans shippers that caused that amazing au to go up in flames. Anyway, this is a au where Sans remembers each and every reset in vivid detail. He slowly starts to lose his mind each reset after another. He becomes heavily depressed and develops an extreme case of insomnia from the constant nightmares he has. Pap and other characters close to Sans notice and become extremely worried for the skeleton. The story takes place after the 999th reset when Sans has long gave up on counting how many there have been and just isn’t the same anymore. He is secretive, tired…oh so VERY tired, jumpy, always on edge. He’s closed off more than ever and rarely comes out of his room, let alone talks to is friends and his little brother….

Summary
Papyrus hadn't been worried! ...Well. Maybe he had been, just a bit.
It'd been a while since anyone had heard from the human, so he called to check on them. But when a conversation revealed just how young they were, he realized things had to change. They were all on their own down here. And... They had nowhere to go.
Well! If there was no one else to take care of the baby bones, Papyrus would just have to do it himself!
—
Sans was trying to get through life and ignore the apathy that had settled over him for Papyrus’s sake. It was just so hard to care about anything when he knew none of it mattered. But when Papyrus had him bring the anomaly home like a lost puppy, things stopped adding up.
How could such a sweet kid be responsible for the relentless time loops?
—
Frisk was used to being on their own, and they were pretty good at taking care of themself. But—Well. ...Dying hurt. They just wanted to get back to the surface! With Undyne in the way, they were hopeless.
So when a phone call from Papyrus somehow ended with an offer for them to crash at his house, Frisk could only be relieved for the break.
They could afford to rest for a while, right?

Summary
The Underground is no place for children.
Toriel rules with cruelty and caprice, Asgore kills in the name of mercy, and Sans and Papyrus enforce the Queen’s will with bloodied hands. Every human who has fallen before has been slaughtered.
But when a silent, nonverbal child falls into this world, something shifts. Spared by Toriel on a whim, caught between Sans’s suffocating loyalty and Papyrus’s cold protection, they must learn to survive without words in a kingdom built on violence.
This is not a story of heroes or redemption. It is a story of survival, miscommunication, and the fragile bonds that grow in the darkest places. -

Adventures of Papyrus: Interdimensional Social Worker by Irongor
Fandoms: Undertale (Video Game), Percy Jackson and the Olympians & Related Fandoms - All Media Types
16 Sep 2025
Tags
Summary
Disbelief Papyrus fails to save the human from themselves in the end, but now that he's been blessed by a wizard with a social worker certification, he won't fail anymore children, he will travel across the multiverse and save as many children as he can.
This is going to be a multi-fandom work where Papyrus travels around saving kids from different bad situations from their not good situations, this is a crack fic, but it will also deal with some heavy topics, I am not attempting to make light of any of these topics, and if this story seems like it's not your cup of tea, feel free to not read. Make sure to take care of your heart and brain.
Trigger warnings for what is happening in chapters will be in the start notes for chapters because some of the kids in fandom are in not good situations that can be triggering for some people, so I will be upfront about what is in a certain chapter and will do my best to make sure it can be skipped over easily. I will also be adding any trigger warnings to the tags when I write them.

Tags
Summary
Calcination: The process of heating a substance just below melting point to induce change in physical and chemical properties, to remove impurities and ensure specific reactions and outcomes...
Grillby has a perfectly normal attraction to his long-time friend and nightly regular at his bar, Sans. He's been dying for a chance to act on that attraction but keeps backing-out before he can follow-through. After patiently biding his time for the perfect moment he finally makes his move.
Sans is contently unattached to anyone romantically. He has his friends, he has his brother, he has the bar and Grillby's usually quiet but comforting company. What more could he need? He hasn't considered a life outside of living with his brother and the occasional random hook-up to blow off steam. Sure, he's noticed Grillby, he's not blind after all. But from the outside looking in, it's always felt like Grillby was just as happy being single as Sans is. Being a single dad, even with a grown kid, probably changes your standards for a partner anyway. Well, until Grillby kidnaps him that is.
Waking up chained to a bed kind of changes your perception of a guy.

Summary
Papyrus knew something was wrong with his brother—people didn't drop their HP Cap for good reasons, after all. But last he'd checked it was much higher than ONE. With terror in his marrow and his brother staying stubbornly silent about whatever was going on, Papyrus decided it was time to call in the cavalry, because he would be damned if he stood back and watched his brother Fall Down and Dust without doing anything.
OR
Papyrus realizes that being on the Surface hasn't helped his brother's crippling depression, because his HP is still 1. So he decides to bring the others in on his brother's stats to try to help.

Summary
She felt her soul being yanked backward, and so her body followed along. She fell on a patch of grass just near the bridge and didn't quite bother standing up.
The sound of the trousle of bones came near, and eventually, a tall skeleton was looking down at her. "HELLO HUMAN! YOU HAVE TO BE MORE CAREFUL, YOU MAY HAVE FALLEN THERE!" his voice beamed.
The skeleton struck an oddly heroic pose before continuing, "LUCKILY FOR YOU, I, THE GREAT PAPYRUS WAS NEARBY! NYEH HEH HEH!"
Or...
As Papyrus ventures out to retrieve his scarf from the underground, he notices a potential friend falling off a bridge.

Summary
There was absolutely no reason for a small, fleshy human to approach a creature known for eating small, fleshy humans.
Which meant there was only one possible explanation for the human child that sat across from Papyrus—they didn’t know he was a siren. This farce of a friendship was an accident waiting to happen, yet… Papyrus couldn’t bring himself to tell them the truth.
He was way too busy trying to convince Frisk to get a sense of self preservation. That was truly the most unnatural thing about this entire scenario. What happened to spikes and traps being pillars of youth?!
—
Mama always told Frisk not to mess with monsters. Any that would risk coming close to humans were, more likely than not, the ones that ate humans. And Papyrus was undeniably one such monster—wickedly sharp spines along his bones, claws that could slice through stone, and a hauntingly alluring voice despite its rasp… He was a siren.
But when Frisk approached him and emerged very much not eaten and instead with their first real friend in years, they came to a pretty obvious conclusion.
He kinda sucked at being one.

Summary
After thousands of years, monsters are finally free!
However…only Frisk is realizing what “free” might really mean, and now she’s afraid that the world she led them into might be so far gone that it could kill monster-kind.
How could she explain to the people who had put all their faith in the surface what a nuclear bomb was? How could she tell them all she’d already given up, once, before she’d ever begun claiming there was hope?
Now she’s scrambling to protect them while violence begins to escalate and whispers of “the third” are beginning to circulate. But Asriel is still back there, and Frisk refuses to leave him behind. Besides, she still has questions to answer. Why was the Underground like a twisted mess of black tendrils that all wad up in some central dark mass? Sans calls it an anomaly in time-space. Frisk thinks it’s more like a pane of glass, struck from the center.
All she knows for sure is, to give monsters a safe world to live in, to let humanity finally have some peace, she’ll take the world as she knows it and tear it apart with her own hands, even if it means destroying herself along the way and never finding home.
After all, home is where…

Summary
Not that he would ever directly say so. He isn't very good with words in that regard, but...
His brother is his whole world.
A few tears on his own part would never be anything, if he could trade them in just to get Sans to smile.
