Summary
“What are we going to do?” Miles whispered the question into the air, sitting down heavily on his hammock. It swung and bounced a little because of the elastic webbing holding it up but didn’t flip. “It’s like we got everything we wanted and everything we didn’t all at once. I mean-” he turned to look at Shadow imploringly.
Shadow didn’t speak, letting his companion get his thoughts out without interruption. Shadow used his webbing to cuff Error’s limp hands together in front of his body.
Miles took it as a cue to continue. “I mean, we wanted this! This was the goal all along! We wanna be able to save people, not just sweep away their graves.” His voice got quieter. “But what can we do with them? With him?"-
Rejected by the primary "guardians" of the Spider-Verse, an alternate Shadow the Hedgehog and Tails (Miles) commit to making a place for themselves in a separate part of the multiverse as they watch over the expanses of worlds in their domain. What they certainly weren't counting on was taking anyone else into their tiny, close-knit group. But here they were. A couple misplaced Sans's later and their numbers went from three to five quicker than they could say "Arachno-Humanoid Poly-Multiverse."Series

Summary
Error has a single, thankless job: tear apart every last abomination Ink dares to call an AU. It's routine. Easy. And mind-numbingly boring as hell now. And no matter how many universes he erases, the voices never shut up.
And when Nightmare offers him a place to crash—complete with chocolate and silence—Error sure as hell didn't accept it.
But he doesn’t throw the offer away.
Something’s building in him, and for once, it’s not just rage. It’s something worse.
---
Or, how Error slowly gets closer to Nightmare's gang (as much as he begrudges it). -

Summary
This story is heavily inspired by the works of @camarondelacuadra. I was given permission several years ago to make this story, however, if he sees this and revokes his consent I will oblige and delete this immediately.
------------------------------------------------------Dream Sans is one of the beloved peacekeepers of AUs, as well as the Guardian of Positivity. Error Sans is the infamous destructor. They could never be together. Dream, however, doesn't see the issue. He admires and respects Error in all that he does, much to Ink's chagrin, and Swap's bewilderment.
He will do anything to have him. To love him. For him to love him back. No matter what, or who, gets in his way. They were destined for one another. Weren't they?

Summary
While the characters believe the multiverse has existed for thousands of years already, it truly starts with the first sentence of its story. Only Ink feels when it happens.
(...And then panics because he's now aware he's never actually protected a universe or had a conversation with a friend and probably doesn't know how to do any of that and they're all counting on him.)

Summary
Fresh isn’t a big fan of the Anti-Void… While it’s nice and bright, it’s colourless and bland— not the parasites forte. He also makes sure to stay a safe distance from Error, but he still catches glimpses of his blue strings and some of his sewing. He doesn’t know much about this guy right now either.
Few things tend to disturb or even raise interest in the virus when it comes to new environments, but something special about the Anti-Void was the voices.Fresh pays everyones favorite guy ever a visit(accidentally).

Summary
Dream stared at the endless white and shuddered against how oppressive this place was.
His eye lights focused on the only thing here.
There was a skeleton on the ground with his hands over where his ears would be. Most of the skeleton had turned dark with glitches and the occasional error but part of his face and some of his left arm and torso was still white. He wore the typical Sans hoodie but with different colours and red glasses.
He was muttering to himself.
"Are you okay?"
A.k.a: What if Dream had met Error before he completely went crazy?
(This fic is inspired by For the Forgotten Ones.)

Summary
Error didn't like when it happened, didn't like that he had them at all, didn't like that he'd been born with something that didn't even make sense for Skeletons to suffer through. But it did happen—every month, like clockwork—and oh boy, was Error about to bite someone's fucking head off.
Error whimpered as another wave of pain flared, his back arching upwards as his skull fell back. He clenched his teeth tight, refusing to make any noise, and his eye-lights flickered on and off with each painful throb. It was accompanied by the sensation of nausea, but he didn't have anything to throw up anyway, so he was left dry heaving pathetically.
The glitch hissed to himself and rolled over onto his side, curling into a tight ball again. He wasn't sure how much more he could take, how long this particular bout of suffering would last, but he didn't have a choice anyway.
Just a bit more. Just a bit longer.
He could handle this. He was strong enough. He'd done this thousands of times.
…
Oh, who was he kidding?
Error wanted to fucking die.

Summary
In one multiverse, there is chaos.
A Creator unknowingly tips the balance, and a Destroyer writhes in pure pain.
The multiverse is governed by Fate and observed by Destiny, Karma, Light, Dark, Death, and Life.
But what no one realizes is—they are not the first.
Fate once created another multiverse… then abandoned it. Destiny, however, did not. Destiny gave it freedom and continued to watch over it.
When the Destroyer is cast into the Void and crashes into that forgotten multiverse, they take him in as their own.
And there, two beings—a skeleton and a human sorcerer—fall in love with him.
Original FGOD!Error belongs to Harris6 (Wattpad)

Summary
When Sci had gotten trapped in the Save Screen with Geno, a future version of himself, he wasn’t sure if he would ever be able to get out. With Geno’s help, Sci had escaped, promising to come back and get Geno out as well. In another multiverse, another life, this goal was accomplished, and they both lived free and happy.
This is not that multiverse.
In this life, it’s been years since Sci had escaped the Save Screen. When the tracker he constructed finally located Geno’s signal and created a rip in reality to lead him straight to his friend, he stepped through without a second thought.
Now he’s trapped again, and instead of finding Geno as he’d intended, he’d unintentionally stuck himself in the Antivoid with Error, a destroyer of universes who tries to kill him at first sight. And there was no trace of Geno anywhere.
Now Sci has to find Geno, get out of the Antivoid, and avoid getting killed, all steps that Sci failed the second he left his universe.
or
Sci gets isekai’d while looking for Geno, but instead of going on a magical girl adventure he ends up becoming permanent roommates with Error. No one is happy with this.

Summary
Strange things have been happening recently.
Naturally, you went to Sans, the only guy who might have an idea as to what was happening. And then he claimed to not remember Geno, your boyfriend of five years.
And then a graffiti-smeared blue skeleton broke into your apartment.
Bottle spray didn’t work. All your projectiles were dodged, and your traitor of a cat freaking ran away!
Who the hell is this guy!?
And why is he claiming to be your boyfriend??
——ERROR 404——
OR:
Geno got yoinked into the anti-void while you two were dating and now you gotta deal with this sad wet cat of a skeleton. C’mon, give him a chance! He’s just a poor little meow meow! (Comes with trust and abandonment issues! Yay!)
But hey, at least you got your boyfriend back? …Kinda.

Summary
Ink is forgetful, sure, but he remembers basic, necessary things, most of the time. So when Error finds him clueless, unable to remember how he got there or any of the people he interacted with, it's nothing short of a good opportunity. Ink knows where the Omega Timeline is, so Error can just go there and destroy it, right...?
Turns out, Ink's memory is still limited at best, which leads him and Error on a hunt for more clues about Ink's previous life in the Omega Timeline, revealing a side of Ink Error never knew about.
...All he needs is for Ink to never remember who they were to each other.
