Summary
Several years after Error’s suicide, the Stars and the Council finally realise just how wrong they were about him. Their multiverse is falling apart. And so they decide to bring in an alternative version of Error from another multiverse.
However, they fail to take into account that he has absolutely no desire to fulfil his duties — he does not want to destroy. Even after persuasion, threats and manipulation, he does not change his mind.
Well then. For the sake of the multiverse, they were prepared to do anything. Even to turn the stolen destroyer into a virtual slave, who, under very real threats of a fate worse than death or torture, submits to their will.

Summary
Reaper lost Geno a long time ago. Years passed, worlds changed. Their son, Goth, was long grown. But the pain never let go of the god of death. It lived in him like a weed woven from happiness and memory.
Error thought of himself as someone who didn't need family, warmth, happiness, a home — he didn't experience it, and the dead, broken feeling inside when he looked at something like that from the sidelines, was was just that. a mistake. He shunned others, and they shunned him back.
This was how it was supposed to go on — quiet, silent, lonely, meaningless.
Until Error began to remember something. Something that had been hidden for years in his memory, something that was breaking him, and something that caused Error to suddenly find himself next to Reaper, withholding information about who he used to be.

Summary
Error lost one fight after another to the Star Sanses. The Universes and code problems kept piling up, and despair drove him to do anything. He tried everything—different strategies, plans, traps, code combinations—but nothing worked, and he remained stuck, with unfinished work and voices behind him.
Until one day, he was embarrassed to discover that suddenly, after so much magic had been spilled by him and his enemies during fights, he could... Invoke a certain, intimate part of the ectobody without their knowledge and influence it as he pleased. Of course, Error was not going to use this! No way! He had principles! Pride, after all!
But... Every day it became more and more difficult, and no other options appeared. And if he could overcome his embarrassment and shame, then maybe it would be worth it?..

EFFECTIVE PLANS TO TAKE OVER THE MULTIVERSE FROM KILLER by Spruce44
Fandoms: Undertale (Video Game)
28 Dec 2024

Summary
Killer's writing skills were highly questionable. His head, too, had long ago lost its sanity, but his thoughts were sometimes so diverse that any madman would be frightened. Once he decided to help Nightmare by making him a list of tactics and strategies that he considered the most successful for capturing the Multiverse or at least some ABs in it.
And even his first paragraphs were frightening:
* Perform a striptease in the middle of battle, thus tactfully distracting the enemy (one of us should do it, preferably a Nightmare) while the rest of us attack the distracted enemy. Repeat the practice in each world, preferably adding something new each time.
* Have a no-holds-barred fight in the mud
* Or in oil
* In grapes would be good too
(The list went on and on, and Killer was unstoppable...)

Summary
The X-Event was a century ago.
The Omega Timeline, once an empty white void, has now transformed into a bustling heart of the entire multiverse, lead by The Council: A collection of the strongest and wisest figures in the multiverse. Under their watch, the Omega Timeline was safe from Error and his never-ending slaughter of worlds.
But when Error is discovered in the timeline by guards, things begin to head south quickly following his arrest and imprisonment. Ink, the once benevolent protector, begins to grow suspiciously distant, and Error's life hangs in the balence of those who wish to help him, those who wish to hurt him, and those whose motives are unknown.
And in the middle of it all, Gradient begins to uncover the secrets of his own past.
————
A story not about about Error and Ink's relationship, but rather an exploration of the consequence it would have on the entire multiverse as they know it.

Summary
‘They say curiosity killed the cat. Some people forget the latter part of the iconic phrase. ‘And satisfaction brought it back.’ Error didn't know if he fully agreed with the saying. But he was putting it to the test today.’
Or
Error questions if tying people up like how he does with his strings is a turn-on and wants to try it for himself. But of course things don't go according to plan

Summary
Without saying anything, Error merely did what he's been told and circumvented his way around the other's desk with the motion of someone carrying heavy rocks underneath their feet. Did the temperature suddenly rise or was it the work of his imagination? It must be the increasing beat of his soul, but feeling cold would make more sense though? This is weird… This is really—
… Is that a fucking boner?!

Summary
Like most nights, hung with plastered stars and moonlight, Error isn’t sure how it starts.
One moment, Error was content, eyes focused on a new knot of string, fingers gliding through the air like puppeteers, sitting at the edge of his mattress. Then the next, Nightmare was before him, fallen to his knees with a sunken desperation to his face. There was an unmistakenable shake to the man’s eyelight— a candlelight in the dampened bedroom they shared.
Trembling, the man had planted his fingers onto Error’s knees and whispered his name with sacrary.
“Error. I need you.”

Or, Errormare finally let themselves free from their battle of control.
