Summary
Cross learnt from a young age to not complain, to keep his head down, to do tasks without being asked to do them and not seek credit for them. He learnt from a young age how to manage other people’s emotions, to keep them happy because the alternative always ended in tears and pain.
Life with Nightmare and the gang is different. They don’t expect things from him, don’t wish him harm. But years of trauma cannot simply be forgotten. Habits that helped him survive don’t just go away overnight. He tries to keep it together, tries to go about his life as he always has. But the others are starting to notice and they know things cannot continue as they are.

Summary
This fic is more of a what if situation. What if instead of Nightmare taking Cross in, Error ended up doing that? How different would things be?
----
Error watches, unflinching, as the skeleton's giant knife materializes, slicing through the stillness of the void. The vibrant glitches around his fingers pulsate more vividly in response, mirroring the tension. Despite the display of power, Error’s demeanor remains composed, almost amused by the dramatic reaction.
"You can call me Error. As for how I arrived here," he gestures loosely around them with a hand threaded with glitches, "I travel where the code calls, where anomalies beckon. Where the multiverse needs cleaned of anything that could harm it, and this place," he pauses, glancing around the stark whiteness, much like his own home, "Screamed for attention."
His gaze settles back on Cross, the colorful chaos of his form stark against the void. "You, however, are an interesting anomaly. Fighting so fiercely, clinging to existence in a world that has seemingly been erased." Error hummed, eyes still searching.

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
For some individuals, memories run so deep that they can remember the very moment of their birth—their first cry, their first scream—and even the admiring “oohs” and “awws” of their parents as they marvel at their newborn. While most parents cherish the new life they’ve brought into the world and envision a promising future for their child, Ink and Error were different.
They were always at odds—two forces clashing in a strange, never-ending battle. Their fights, filled with broken bones, scorched paint, and snapping strings, might have seemed dangerous to an outsider, yet the two secretly knew that they’d never kill each other.
Then, during their fight in the Anti-Void, something unexpected happened. Right beside them, a large splotch of ink appeared out of nowhere. It swirled and shifted until it formed a small, bony figure with a surprisingly whiny voice that sounded liquidy, as if the small thing was underwater.
“What the hell is that?” The Destroyer growled, narrowing his eyes and pulling tighter on the strings that connected him to the Creator.

Summary
After a nasty fight, Error is left picking up his broken body— only to hear the cry of a child that should never have existed in the first place.
It happened in an instant, the realization. The sudden understanding of what this was. Who this was.
He could feel it in their magic, could feel it in the way their Soul called out for him like it would a parent. This was the result of Creation and Destruction mixing in a way that was unnatural, impossible, and yet undeniable. This was the spawn of two beings that should've never been able to create life together, brought into existence by magic that should've never been able to mix.
This was his child.
His and Ink's.

Summary
One day, several of the deities overseeing some multiverses became bored. Out of boredom, they ended up having a httyd marathon. This inspired what happened next. They took some multiverses that had settled into a rather ordinary, boring pattern, and merged them. They turned several humans and monsters into dragons, more specifically, Dragons or hybrids based on httyd. Now, everyone is confused and trying to adjust to their new lives.

Summary
When XGaster was defeated and X-Tale was restored, the universe as a whole made it clear to the wider multiverse they wished to be left alone. They did not wish for multidimensional visitors, didn’t want to be disturbed by the hustle and bustle of Gods and outcodes. This was respected and they didn’t contact the outside world other than to demand Cross’ return, stating that as he was underaged and a native to X-Tale he belonged in his home universe. It had resulted in a somewhat long custody battle between the X-Tale natives and Nightmare and Error that was settled by the multiverse council. The council had decided to allow Nightmare and Error to keep custody of Cross due to evidence of past child abuse.
Everyone thought this would be the end of it, that they could continue living their lives in peace. It would seem X-Tale was more determined than they let on to retrieve that which they falsely believed to be theirs.

Summary
It came as a surprise for Cross to learn that every single inhabitant of Nightmare’s castle had a pet of some description. Killer had his mancoon cat Bigwig, Dust had his two rats Daisy and Holly, Horror had his three chickens Gwendolyn, Gertie and Sasha, Nightmare had three freshwater fish tanks in his study and even Error had the stereotypical pet rock most Sans’ and Papyrus’ had. It came as even more of a surprise when Nightmare approached him one day and offered to get him a pet of his own.
TLTR: otherwise known as how Cross got a pet of his very own

Summary
Wind blew gently in the abandoned place. Well, he supposed it was abandoned. He hadn’t heard any voices nor footsteps for a very long time. Only the rare flickers of dead leaves and the cracks of broken wood replaced the never ending silence. It has been a while since he had seen the hill, so he wasn’t sure if his idea of the place was correct. Though he could feel the dry, withering grass on the ground.
How long had he been imprisoned there ? He remembered the flowers that once grew where now death had found a home. But in this jail, he was unable to discern time or.. Anything at all. He was barely aware of the fainted moonlight that brushed over his stature. His thoughts were mere shells of whispers. He felt completely numb to everything all at once, as if he were made of stone.
Until he wasn’t anymore.

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
Coming back from after he fell, Error was expecting a lot of things. He can't say he didn't expect this, but somehow it still makes him angrier than he's ever been.
