Summary
After losing your dad at eighteen, you did the impossible. You became the legal guardian of your curious, chaos-prone little sibling, Frisk. Now at twenty-three, you've just about mastered the art of burnt pancakes, last-minute science projects, and saying "no" to whatever ridiculous idea Frisk has next.
Unfortunately, their latest obsession?
Mt. Ebott. The "cursed" mountain no one returns from.After weeks of relentless pleading and very dramatic puppy eyes, you finally agree to take them—just to look. With supervision, obviously. You’re responsible.
But the next thing you know?
You both fall down a hole and land in a world full of talking monsters, glowing flowers with a god complex, and… a pun-loving skeleton who might just be more than he seems?Well.
So much for a quiet weekend. -

Summary
Toriel crouches to be at eye level with Frisk. "What's your name?"
"Alpha Mega Rizz Gyatt," they respond automatically.
Toriel looks confused for half a second before nodding as if the name makes perfect sense. "Well hello, Alpha Mega Rizz Gyatt, would you like some pie?"
Huh. They hadn't expected the prank to work. "Call me Frisk, and yes I would fucking love some pie. I'm so hungry."
Or a totally not cringe story ;)

Summary
Frisk is your baby and you’d do absolutely anything for them. Every bit of money you make from your three jobs goes to them. Then, after a messy encounter with their father, they go missing.
You never expected to see them emerge from mount ebott with a whole new race of people. With monsters.
Once again, you’d do anything for Frisk, even if that meant abandoning your apartment and living with monsters. But hey, maybe it’d be good for you to make new friends, form new relationships. It had been awhile.
And you find a certain skeleton very funny.

Summary
Sans isn't looking after himself anymore.
He barely gets out of bed, barely showers, and barely eats.
Papyrus is making it big out there, and Toriel has the potential of becoming a teacher within her grasp.
Left alone to assume the role of Frisk's deadbeat uncle while everyone else achieves their hopes and dreams, he feels like he's been handed the short end of the stick.
Frisk decides the best way to help Sans is by shoving him into a series of awkward encounters with their single mother.
So, when Sans notices they're playing matchmaker to try dragging him out of his destructive cycle, he tries to stop it, though it's too late.
He already has a cute lady wanting to jump his bones and rattle him up, and all it took was making himself look decent for a date to McDonald's and Baskin-Robbins.
(Mostly told from his perspective, but there will be chapters featuring Second Person POV.)

Summary
You first see it when you’re half-distracted, slamming numbing palms into walls to see just one more secret, one more passage. You open the first door you see and it’s there, greyed out and hollow, not so much standing as just existing in the center of the room. Its face looks cracked, forever stuck in unmoving pieces, a stillness so unnatural that it sends a bolt of fear through your chest. You freeze. It doesn’t react.

Summary
So it turns out that surviving on the surface is significantly harder than saving an entire civilization, build-a-bearing a body from sheer spite and force of will and outliving a whole world being wiped out of reality. Who knew?
Chara and Frisk have somehow crossed the barrier and now it's time to brave the surface together. It goes as well as anyone could expect.
Some backstories are revealed. (Some more reluctantly then others.) Some food is scavenged, salvaged and eaten. Some... is not.
Frisk and Chara learn a great deal about each other and grow even closer than in the Underground. They might be technically homeless but when has that ever stopped them?A direct continuation of It's not chocolate but it's still pretty good. Just like with any installment in this series, you don't need to read the other works to enjoy this one.

Summary
Thousands of resets, and yet their boredom wasn't satiated.
They’d done it all. Genocide. Pacifist. Neutral. Every route. Every secret. Every hidden flag. The Underground had become less of a world and more of a toy box for them, just a play to be manipulated, and lines of dialogue to be read.
They were a survivor. A murderer. A saviour. A monster. A friend. A stranger. A god. A ghost. And none of it meant anything anymore.
During a True Pacifist run, right at the end, standing beneath the sun with all of their "friends" gathered around, they turned away and opened their menu again.
they reached for the reset button. However, the reset button displayed a question mark. An unusual phenomenon. But having already reached for it, they pressed it.
Suddenly, the blackness of a void appeared.
When they came to once again, they were no longer lying on a flowerbed, with a flower waiting in the next room.
Instead, they were standing in a busy street filled with humans and... monsters?
No, they weren’t in the right universe anymore. They were in an entirely new one, completely uncharted to them.
This time, it was their first neutral run, in the capital city of Lugunica.

Shiftfell Frisk found that flirting was a great way to get past monsters, and so uses it on Asriel and Chara.
Totally not because he liked being a shit. If it works don't fix it as they say!

Summary
Once upon a time many centuries ago, the world was ruled by two species: Humans and Monsters. Both of these creatures thrived together using their special talents to help one another. That was until the humans declared war on the monsters out of the blue. This led to the monsters to be banished beneath a mountain.
But rest well when I say the humans suffered their karma. Without monsters they soon lost their magic, along with their way of life. They developed their own powers called quirks, with this power came the raise of heroes and villains. Quirks were quick to spread until only 20% lacked them.
It wasn’t long before magic and monsters were reduced to legend. This led many to climb the mountain to see if the legends were true, only to never return. This was because of the heartbroken monster king who put a bounty on every human who fell.
When the last human fell, the monsters were ecstatic. Finally they’ll be free to wander the surface and feel the sun and the rain again! But unbeknownst to them, they have become even more trapped than they had before. With each reset the monsters were forced to live the same day over and over without anyone knowing ... .Well, almost everyone.

Summary
Hush now, little one. I have a story to tell. A story about humans and monsters.
Frisk Estrella lived on the surface, and was just one face in the crowd of thousands within the large city. Buckling under the pressure on his home life and internal forces preying at his mind, the last think Frisk wanted was to end up being on the run from the cops. Unfortunately, some don't get a happy life.
After a confrontation leads the boy wanted for murder, Frisk ends up in the bottom of Mount Ebott, where he discovers a civilization of mongers just below his feet. To anyone, they would be horrified, and would try and venture through to leave.Frisk however, finds himself growing familiar with this place of monsters, and soon enough, thinks about staying. But as he makes friends and allies, hundreds of years of history begin to rear their heads as Frisk must confront enemies that could threaten not just the Underground, or humanity, but the very nature of existence as well.
In order to save his friends, and himself, Frisk must have DETERMINATION to survive.

Summary
'She was always the adventurous kind, right? Her just going missing for two days is fine, Right?!'
Y/N had always been... aware. Whether it be a small, useless detail about the world around them. To the entire personality of the person in front of them. They always seemed to know everything they needed to.
Yet when their sister went missing, when days started repeating over, and *over* again. The top of Mount Ebott, the place no one returns from, sounds less like a threat from a lost time, and more like a release
---------------------------------------------------------
'the kid's still going? huh... i doubt that'll last much longer.'Sans had seen everything. He'd been through *everything*. Genocides, pacificism, death, and resurrection. A never-ending loop he could only sit and watch, never being able to break from the cycle he was forced into by the morbid curiosity of a child who could barely comprehend the power they wield. Yet, the timeline had never lasted this long
