Summary
It's been six years since The Barrier was broken. Ebott has adopted monsterkind as its own, letting them settle in the tiny country. The re-discovery of magic has revolutionized technology and development on the Surface, with Ebott being in the middle of it. The future seems bright, humans and monsters are bretheren, and the world just keeps getting better.
You couldn't disagree more. Will anyone be able to change your mind? A certain scarf-clad skeleton certainly thinks he will.

Summary
You had a serious problem. You had a big, fat crush on Sans. The only reason it was a problem... was because he was the brother of your best friend. How were you supposed to hang around him if whenever his brother came in the room, you were a blushing mess?

Summary
You wake up in a world unknown, with no memories of your life up until this point - not even your identity. After leaving The Ruins, you are left to face a strange and unfamiliar place alone; that is, until you meet a wise-cracking skeleton with his own set of equally mysterious problems.
Together, you set off on an adventure throughout the Underground, seeking what has been lost; your memories, the way home, and the whereabouts of Sans' beloved lost brother. Many twists and turns await, with secrets unfolding, your bond with Sans growing all the while. And, of course, there's the friends you make along the way.
A semi-AU Undertale "retelling" with some twists and changes, a Sans-centric storyline and a pacifist heart beating at its core. (Reader-perspective, but there is NO use of Y/N)

Summary
Unwilling to kill to claim a soul—or to strike down the monster king to escape—Frisk chooses to stay underground. The monsters crown her their princess, and she grows up among them, a symbol of hope and peace.
But shadows from the past refuse to stay buried.
When the fragile peace begins to crack, Frisk must face what she's tried to forget. Alongside her childhood friend, Sans, she sets out to protect the only home she's ever known—and the people she loves—from a threat that spans timelines.
With original art. Inspired by Seventh Soul by 8TheKat

Summary
Hasn't been going so well for Sans lately.
On top of Papyrus moving out and being un-invited to a wedding, he's begining to think he'll simply fall into the background and be forgotten, and he was willing to embrace that.
That is until he met a strange killer named Jeff within his own kitchen, with many more like him on their way here.
This isn't going to end well is it?
TLDR: The Creepypasta gang try to assimilate Sans into their ranks.

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
Cassidy always found herself entranced by the idea of her soulmate. Fantasized about just sitting with whoever they were in cozy company, especially after finding herself homeless in Ebbot City. Not even the emergence of monsters could hurt her hopes to one day find them and just have someone be there for her and her returning the favor.
When less than ideal circumstances do arise in which she meets him though, she can't bring herself to find him again after parting.
Why would she when the first time meeting her soulmate results in a death threat?

Summary
A collection of connected and unconnected one-shots (Even the unconnected ones will reference others), requested in the Discord Server and prompts that I wanted to explore further. One-shots will be of both Merging Timelines and Multiverse Madness, and each chapter title will show which story it's from! There may also be AUs of Merging Timelines and Multiverse Madness in here, and those will not be Canon to either story line. Also, not keeping the fonts for the MT boys, so them being missing isn't a mistake or anything in case you're wondering.
Note: The one-shots have random lengths. Some will be as long as a chapter, and some will be shorter. There will also be multiple parts to some one-shots too, depending on the plot.

Summary
You run a café. You mind your business. You serve caffeine to monsters, tolerate regulars, and try not to set the espresso machine on fire.
So when “Sans” walks in acting weird—untied sneakers, hoodie with fur, telling jokes your Sans could never land—you know something’s up.
Turns out he’s from another universe. And somehow, he’s made himself very comfortable in yours. Including on your couch. And maybe… your neck.
You’ve already got one Sans. You don’t need another.
Now your life is unraveling. Shortcuts are glitching. Mirrors don’t show your reflection. And the stranger who shouldn’t be here keeps looking at you like he’s known you through a thousand timelines.
He calls himself a mistake.
You call him everything you were afraid to want. -

Summary
My version of Flowerfell. Frisk, Chara, and Flowey are the main focus because I think this friendship has a (skele) ton of potential that's sometimes overlooked.
I will not be shipping Frisk, Chara, or Flowey with anybody, including each other. In this story, Frisk is seven, Chara is thirteen, and Asriel/Flowey is twelve. I will include a few scenes of Sans x Grillby, and I may include Papyrus x Mettaton, but I'm not sure.
There will be angst, and a closer look at how Frisk's health would be affected by buttercups growing out of their skin. If you don't know what that would entail, please do research before reading. Saying that it isn't pretty would be an understatement.
There will be fluff and fun and shenanigans, it isn't JUST angst.
Edit: I decided to add in an original character. Boom. -

It’s fine, you have plot armor.

Summary
You wake up, and you don't know where you are.
You don't know who you are, or why you're here.
You don't know these people.
And you most certainly don't know who he is.
. . .
There is one thing you do remember, though.
And only one thought is clear in your mind:
Above all else,
you need to find your sister.

Summary
Sans did not remember his previous name, only that he had been human. Rebirth in Undertale was novel, but he adapted, until he realized that the universe he was in was not the original one.
Unfortunately, it was too late when the machine took him to another universe, into a room full of skeletons.
——————————————————————————————
Sans no recordaba su nombre anterior, solo haber sido un humano. Renacer en Undertale fue una novedad, pero se adaptó, hasta que cayó en cuenta de que el universo en el que estaba no era el original.Lamentablemente, ya era tarde cuando la máquina lo llevo a otro universo en un cuarto lleno de esqueletos.
Nota: Sé que suena como tragedia, pero en realidad es una historia bastante esponjosa de curación, o al menos eso intento. Nuestro protagonista tiene mucho trauma y lo va a sanar en una mansión llena de esqueletos incómodos

Summary
Tears always came easily to Murphy ever since they were a child. Fighting through life feeling misunderstood and alone, a deep sense of despair and overwhelming sadness became their most common reason for crying.
After all, nobody climbs Mt. Ebott for a happy reason. They were no exception.
But perhaps what awaits Murphy in that dark abyss is not their death, but their rebirth. Aided by colorful characters as they navigate the Underground, they rediscover joys thought lost to them and are confronted by the very essence of their being – and must decide whether to let it wither, or to let it bloom.
