Summary
Twin Runes es un AU cómico en su mayoritariamente alegre centrado en los universos Deltarune y Undertale. Una fuerza desconocida ha provocado que aparezca un punto de conexión entre los dos universos, lo que hace que Frisk y la molestia fantasmal Chara tropiecen en la vida de Kris en uno de sus muchos reinicios (para gran disgusto de Kris). Se produce un caos que rompe el juego.

Summary
The clock ticked loudly in the background, no longer drowned out by the talk of drunken patrons. Grillby sighed, slinging the towel he was using to wipe down the counter over his shoulder as he ran his fingers through his flames- …thinking about it, he supposes it could be called hair- no matter. The bar closed over thirty minutes ago, and Sans was still sound asleep on the bar. He didn’t mind the skeleton, don’t get him wrong- it was just… inconvenient. He wished that the monster would just, ask him to hang out like a regular person. Instead of forcing him to wait around in hopes that he would wake up and leave before his very loud brother showed up…
Grillby rubbed his face, giving Sans another minute…and then two… and then Grillby gave up, straightening out the towel to whack the shorter skeleton on the head. There’s a muffled “hmph” as the Halloween decoration finally appeared to spark life, resting his head on his hand with heavy eyes. -

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
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 human and monsterkind alike.
However, by merely being present in the Glitchtale Universe, Noelle and the Fun Gang have unwittingly raised the stakes by considerable amount, as breaches in the fabric of the space-time continum begin to appear, allowing people and things 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
That golden sunset is always temporary.
Frisk doesn’t know why, but every time they get their “happy ever after,” the timeline...
It just… stops.
No light.
No sound.
No sensation.
Just oblivion.It all turns

D A R K E R
Y E T D A R K E R
And they reset.
Over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and
What's even the point?
They tried everything.
It's hopeless.
They should just give up.
*But it refused.

Summary
Somewhere in the RUINS, a human falls. This time is no different from the last.
But then?
People are forced to leave those they don't want to leave.
People are forced to lose those they don't want to lose.
People are forced to forget those they don't want to forget.Something snaps. A lone flower watches from afar. A Skeleton anticipates what's to come. And when that day DOES come? The final verdict will be given.
TL;DR - DUSTTALE but it's not JUST Sans centric

Summary
Reality is unraveling. Time no longer follows rules—it bends, loops, and rewinds, pulling souls into paths they were never meant to walk.
As memories clash and timelines bleed into each other, a new force emerges—one that threatens to erase not just the future, but every version of the past.
How do you fight what was never meant to exist?
And what will you become when time runs out? -

Summary
[Premise]:
Clover has been trapped in a loop of running through all the different routes of Undertale Yellow for 10 real-time years.
Right at the end of a Genocide run after destroying Axis, unable to suppress a guilt gnawing at them from within, Clover aborts it.
The gunslinger fights Flowey with an equal level of determination, and the save file gets damaged.The data corruption sends Clover all the way back to just outside Mt. Ebott, and also ages Clover and the world up by 10 years.
Clover has the memories from the last journey they just went through, a few fragments of the other routes, and a vision of a certain laboratory.
The fully grown cowboy decides he has to do things differently this time.No more SAVEs. No more LOADs. No more RESETs.
This is their final shot. Do or die. -

Summary
With the magical healing powers of ketchup, Sans survives a genocide run--but the rest of his world doesn't. He sets out across the multiverse searching for a family he refuses to believe is dead, struggling to come to terms with his new life and identity and making more deadly enemies the further he goes. When a rival emerges, he's forced to choose between his past and future or risk losing both.
Updates weekly-ish
(Yes, this is absolute crack--but I found out there was no AU where Sans's soul is literally ketchup and decided that was a problem I had to solve. There will be family fluff, plenty of angst, a bunch of AUs, and general shenanigans. I'm treating this seriously enough that I forgot how ridiculous this was until I had to write this summary.)

Summary
Clover doesn't give up his soul because justice still needs to be delivered.
The Wild East, and later practically the entire Dunes, declares independence. They declare that any human within their borders is under their protection.
Civil War looms over the Underground.
Would you like to see what happens?
Note: This is NOT a story. This is an archive containing information about my AU, Desert Sanctuary. I might write a proper story in the future, but for now, this is where you can read about the narrative, the characters and how this massive change affects Frisk's journey.
Fanart and other fan works based on Desert Sanctuary are welcome and encouraged

Metamorphosis - Alternate Title: Equally Unfair Circumstances by Rando_internet_Guy

Summary
Frisk has been through a lot. The Underground was quite the journey, with a race of monsters that wanted them dead and an unknown malicious entity that had possessed them, and after a run they'd rather forget the entity is gone. Now, they and Chara are busy trying to help monsters integrate with humanity.
However, there is a reason Humanity doesn't know about magic, and that reason is keen to keep magic away from Humanity, with the belief of the ends justifying the means.
Opposing secret organizations, overseers with plans of their own, finding themselves in a situation where a single kid overturns the status quo that has reigned for decades. A kid that simply breaks all previously known rules.
However, every will can be broken, no matter how strong. So, the Willbreakers lock and load and are sent to handle the threat, with the goal of eliminating the anomaly. And so far, they have done a good job of keeping Frisk firmly in step one.
However, in a distant universe, a human has made a promise to an entity that wishes to compensate for its actions, and through the creation of a Dark Fountain they are now here.
This wasn't how anything was planned, but it will surely be very, very interesting.

System Error: Accidental Acquisition of Children by Frikisbits231
Fandoms: Undertale (Video Game)

Summary
Error slid down, glued to the tree, his back to the ground, into the lush green grass on the ground. Later, he'd take a look at his current situation and possibly eliminate the place without a problem. Meanwhile, Error was resting, leaning against this comfortable, curvy tree, closing his eyes to feel something, something of the place.
Feel... the familiar ambient magic?
Still no monsters, humans, or standard souls around. Well, no one could hurt him if he got some rest, right?
This time, he mentally prepared himself and repeated the safety tests he felt like a mantra so he could get some rest.
He fell asleep shortly after.
…
Sweetness with hints of security, calm, and the tranquility of dawning rest captured his senses. Something... familiar. Like... like chocolate melting on his tongue. He didn't know how he recognized that either. Still, he pulled the tongue out of his space, to capture it. He caught the sensations, almost becoming overwhelmed by them.
(O: The one where Error acquires an abandoned baby bone, which is, of course, his offspring too, yay...)

Summary
A collection of stories, either following a timeline or veering away from it.
Alphys and Sans worked together a long time ago. They even dated once, and were madly in love with each other. Then, they discovered important parts of their identity, and decided to break up so they could pursue their true selves. They're in the middle of wingman-ing each other when an incident happens, and they decide that, for the sake of their friendship, they need to part ways. They don't forget each other, though. The romantics may be gone, but there's a stronger kind of love in its place.
