System Error: Accidental Acquisition of Children by Frikisbits231
Fandoms: Undertale (Video Game)
14 Jun 2025

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
After the monsters win the monster/human war, most humans are whipped out, monsters taking over. Now, in the year 2113, Frisk and Chara are two of the few humans left in BlightView: the monster capital of the world, ruled over by King W.D Gaster, with his adoptive son, Dream, by his side. But like anything, the Castle holds many dark secrets of its own...
And of course, nothing is as it seems in the city as well, as it is that most people who don’t live in or near the city centre have it extremely rough, all being treated roughly and unfairly, living in poor conditions. A rebellion is soon formed in the “slums”, the outskirts of BlightView, run by Error, along with other misfits, like small, rundown Sans, who lives with a grieving Asgore outside of the city, and an enraged Cross, who wishes for nothing more than revenge, and young Killer, a boy who grew up in the slums without parents and a strange medical condition. The rebellion is the city’s last hope.
!!THIS STORY IS NOT COMPLETE!! please read the last chapter for more details, but the TLDR is that I'm working on completely rewriting it!

In Our Little Corner of the Multiverse by Greetings_Im_Leo

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
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
He raised his head with difficulty. His eyes widened in surprise. In front of him was a portal, as glitchy as he himself, and he could see a dark sky with stars.
Error extended his hand and it easily passed through the portal and on the other side a light breeze blew across his fingers. It seemed that strength suddenly filled his body, and the magic responded with warmth and he literally jumped into the portal, turning out to be on an island that flew among the stars.
A surprised sigh escaped him before he sank down again, but now it was no longer the white empty floor of void, but I was soft, cool grass.
Stars, how he loves it here. This place is much better than anti-void.

I'm Willing To Kill Anything For My Kids by Greenspirit_Foxle
Fandoms: Undertale (Video Game)

Summary
Error always felt a pull to destroy, like Ink felt to create, for as long as he could remember. Error earliest memory is of destroying, not in joy or feeling forced, he did it in his madness, and uncontrolled and seemingly aimless rage. Eventually, he gain some semblance of control over himself, leading him to mark non-original aus he enjoyed so he wouldn't destroy them, and properly learn his role, his purpose. However, he didn't shy away, or regret the things he did, he reveled in it. He enjoyed destroying, and thought of his destruction as his own special 'art'. And yet, his destruction has definitely dialed down over the years, and been much more precise.
However, he never would have thought he could create something complex, or so, so positive if it involved his destructive magic, and now four living, breathing children. And he had gained friends along the way he eventually trusts them with.

Summary
"There's only two things in this world you can be, the one that perseveres, or the one whose body is left for the beasts." The stable hand stated weakly.
Ink curled up beside him and tried to ignore the sounds outside his little sanctuary, the rattling of his shaking bones doing little to cover them. He picked at the spaces between his phalanges and stared unseeingly into the stalls across from them. Perseverance? The concept felt so foreign to his young and shaken mind.
How could he possibly persevere when it felt as if he was unraveling?
(A swap au of my dear friends' multi-chapter fic, Perseverance. Detailing a scenario where Asgore had not found Ink on that last search party, and Ink was forced to survive outside the kingdom walls. You do not have to read Perseverance to enjoy this fic.)

Summary
It started out as a joke with Killer asking Nightmare who his favourite kid was. The King of Negativity gave the generic parent answer of not having a favourite while Error had no problem in saying his. They had laughed it off, thinking it a joke. It’s not till the Stars make the biggest mistake in their lives that they realise just how serious Error actually was.

Summary
{A shot fic that I made after noticing that there are few original fics from Minúsculetale, the ones that there are, unfortunately, are tied to the original comic that the creator will no longer make ;-;}
Ink is a young moth, an inventor and owner of big dreams, among them exploring the garden beyond the limits of the colony. However, all his plans are frustrated when his father announces that he will marry him to his then boyfriend Cross, prince of the butterflies of the neighboring colony.
Desperate at the vision of this new destiny, Ink runs away in the middle of the ceremony, entering the dark and unknown woods of the garden, coming across predators thirsty for butterflies, cannibals, insect-eating plants and a stubborn spider.
