Note ~

So if you are confused, when Gaster hit the Overwrite button before he died, he rewrote [Y/N]'s code and made them into the X-Event. The X-Event is basically the term used to describe a person who has control over the Overwrite button and has the power to create and alter the codings of different worlds.

It seemed that all life would end here for no victory was in sight, not ever, nothing would ever live again in this world of white and silence. Error was all that remained, after all, wasn't that what he had wanted? To destroy all the universes until he alone remained with the exception of the main timeline? It wasn't until now Error realised how much he missed it all, the noise, the constant clamour of thigns. Even if it had been a nuiscance, at least there was a song always playing in the Void. Now there was nothing.

The creatures of hate seemed to watch Error for a moment, deciding on whether or not to erase him from existence. "What are you waiting for!" The anomaly screeched, looking at the twitching form of the human beside him. Whatever Gaster had done to them, he didn't want to be around much longer to find out. "Isn't this what you wanted, to kill us all? Well now's your chance, damn you!"

One creature moved forward and took shape, Error recoiling from the sight. It was him, the glimpse into his old self from his dead world, clad in glasses and a lab coat. Those had been simpler times, or at least it seemed, he didn't remember much of anything these days.

"You don't remember me," the demon rasped, swaying from side to side. "But I am all that is left of your deleted world, the hate from our universe. You used to look like this, I saw you from time to time in the eyes of the human that created me. And how much hate they felt for you, all those times you struck them down in the Judgement Hall, how we would be one step closer to the brink only to be pushed away again. But alas, those are memories that belong to the dead and we can only continue, can we not? There are bigger things at hand."

"Bigger things," the other hate creatures agreed.

"Ink's reign is over," the hate creature from Error's dead world continued. "It was seen with the destruction of everything that was ever known or created. The balance has shifted and the universe starts anew with a fresh cycle of characters, new sides to each part of the balance. Should you survive your battle with the human, should you undo whatever effects Gaster has done to them, then it will fall upon the shoulders of both of you to restart the cycle, to bring back the ghosts of the dead.

"We do not wish to see the universe's demise, our only job is to clean up the anomalies left behind. That is our true purpose, but without anything to ever exist again, than what is the point of our being? We cannot live off the corpses of the dead worlds, we can only thrive with life as that is the nature of hate."

"Dead," the others chanted and then dissolved into pools of black liquid, cackling as they jumped through the Void and vanished from view. Error narrowed his eyes as the damned things disappeared and turned back to behold the trembling form of [Y/N]. staring at the ground as muffled whimpers escaped their lips like the groans of a dying animal, whatever Gaster had done to their mind slowly taking its toll.

And then the eyes of the human flew open, [E/C] orbs that seemed to stare into the world they could not see. The eyes seemed to drift for a moment before falling upon Error, the beginnings of a sadistic smile playing on their features. "He told me to kill you," [Y/N] whispered, swaying slightly. "When the hate took him, Gaster said that it was my job to make sure that I finished what he had started. And I'm going to do as he said, a good servant always follows what their master tells them to do.

"Unlike you Error, the one who rebelled against our creator and destroyed his perfect world. But I will fix that for Gaster has made me anew. I am the X-Event now, do you understand? I am the one that will create Gaster's perfect world and make sure that none can rebel or think for themselves, I will make sure that there is one universe and one universe only. Everything will be as it should."

"[Y/N]," Error protested, prepared to summon upon his reserves of magic should they decide to attack. "You can fight this, I know you can. Remember how we fought back in that one universe, the one Gaster tried to throw us into? You can do it again."

"Traitor!" [Y/N] screeched, clawing at their hair and bursting into a fit of giggles. "We fought back against our father's wishes and he died in the end, but we were wrong, I see that now. Even when he learned that we had betrayed them, even at his final hour, my father's last act was to save me, isn't that a wonderful thing? His last push of the Overwrite button was to make me his heir, to transfer that power to me. I am the X-Event now, the one that will reshape the universe and create a perfect world, one that will not go wrong this time. Everything will be as it should be and it will be a glorious new day, but a day that you will not live to see, I am afraid."

The X-Event, how Error hated that word. It had been a scheme of Gaster's, one that the anomaly had been striving to unleash for years. He had tried it before, to destroy the multiverse and create a singular, perfect world without need for any resets. But Ink and his band of followers had stopped him in a rather complicated story and the X-Event had ended, it was forgotten. But now here it was once more, living through the insanity that burned through [Y/N], Gaster's last attempt from beyond the veil to have his obsession live on, to have his perfect paradise.

[Y/N] waved their hand and the glowing form of the Overwrite button appeared next to them, the monstrous purple glow humming ominously in the white of the Void. "But I will recreate utopia after our battle, after our little game. It's curious, really. Ever since we met I've wanted to fight you, to cut that arrogant smile from your skull. Perhaps I really will get the chance after all!

The human opened their palm, a purple dagger materializing in their left hand as they charged, the tip of the weapon aimed straight for his chest. Error sidestepped the attack, not wanting to resort to offensive measures, not yet anyway. "[Y/N]," he shouted over the chorus of giggles that the human sung, "I know you can fight this!"

"[Y/N] is dead," the human sighed. "They died when my father pushed the Overwrite button in the midst of his dying breath. Some of his soul lives inside of me, isn't that wonderful? A part of him will always live inside of me, so I am no longer [Y/N]. I am Chara now, as it was and always will be."

The next attack Error missed within the timespan of a heartbeat, wincing as the dagger cut through his jacket and brushed against his rib cage. It would take nothing more than a tap to kill him, for as all other comedians within the multiverse, he possessed only one miniscule amount of health, the amount of health taken should one stub their toe.

The easiest enemy.

Error allowed the essence of his magic to flow through him and he brought forth a wave of blasters, not allowing them to fire upon the human, not yet. There was still a trace of [Y/N] that still remained, he was sure of it.

"Kill me!" The human screeched, their mouth breaking into a jagged smile. "Do it you damn coward! This is your chance, your chance to claim everything you have stood and fought for! With my death comes nothing and wasn't nothing everything you always wanted, what you fought the painter so fiercely for, for the end of everything except the original timeline? Well then kill me and be on with it, leave the damn universe to rot! No more noise, no more sound, no more anything.

But this was no longer the demented demon that cackled before him, but the human that he had followed through the Outertale universe, the one who had exchanged whispers with him through the echo flowers. This was the human he had given a part of his soul for so that the universe might live, so that there might be a chance still for Ink's forces to drive back Gaster, so that the human might again see another day. They were linked in more ways than one and had become halves to one another through an odd and seemingly impossible series of events, and yet here they stood. Killing the human would be killing a part of himself and Error could not do that.

Perhaps once he could have killed this anomaly with ease, erased their coding as he had done to so many others. But not now, not anymore.

"Why do you fight comedian?" [Y/N] sighed, the dagger dropping to their side. "Even if you do kill me, which is impossible given that I am the god of this universe, what would you hope to achieve? Recreate the world? No, you cannot create for it is against your very nature. You will rot for an eternity in the Void, with no one to live to remember you for all are dead except us. So isn't it best to let the X-Event run its course, to create a new world where there is at least life, where there is perfection?"

"Do you remember the song?" Error asked, shoving his hands into the pockets of his jacket, the blasters disappearing. "You used to think about it a lot, back when things had been simpler. You said that each universe had their own voice to add to the never-ending chorus in the Void and that if one universe was to be eradicated, than the song would change entirely and it would never again be the same. There is no song now, and there won't be a song in the Void with one universe, with no life and no creativity."

This seemed to stir something inside the human. "Hypocrite," they snarled through their teeth. "It was always in your nature to destroy, you relished the idea of the multiverse sinking into oblivion and yet now you want to bring back the dead universes. I find that hilarious."

"Maybe once," Error sighed and brought his soul into view, staring at the glitched thing. "But a human and a slight renovation on my soul helped change my perspective on a few things."

"Anomalies do not change," [Y/N] spat and thrust the dagger at Error's skull, the blade soaring through the air and missing him by an inch. "Nothing ever changes, everything stays the same. That is why we must have a perfect world so that everything changes, do you understand? The cycle cannot repeat, the cycle of repetition where universes multiply without control. With one perfect world there will be limit, there will be control."

"Everything can change, even glitches and anomalies," Error chuckled. "You changed, did you not? The Void changes us all in different ways I suppose. Perfection is error and error is perfection, that is what I have learned, that is what you taught me [Y/N]. Sometimes we need variety, sometimes we need to have a few annoying glitches exist in the Void so that there's a song."

There was a brief pause. Was it possible that a fragment of [Y/N] still remained within the corrupted code, that even after Gaster had rewritten them entirely, a spark of the former human still remained?

"You idiot!" [Y/N] rasped and swiped their hand upward, the knife rebounding and burying into Error's coat, pinning him to the floor. "Nothing remains of your human, nothing! They are dead and only I remain, the X-Event, Gaster's final plan to ensure perfection in the universe. When I kill you nothing will stand in my way, I will be limitless! Everything I will create will be under my control for things cannot want freedom if they have never tasted it."

"Then that's not perfection," Error retorted, his gaze drawn to the knife. "I believe you just gave the definition of a dictatorship. That is not perfection, it is anything but that."

"Liar!" [Y/N] screeched and drew the dagger from Error's jacket and brought it down on his chest, feeling the blade tear through sinews and bone, ripping through the black fabric of his jacket. The human continued to slash, ripping through the material while laughing to themselves, consumed with nothing but insanity. The glitch would die, this was his final hour, nothing would remain but them and they would create a new world, a better world.

When at last the human pulled away, Error's jacket was torn to shreds, soaked in a red material. He brushed his palms against the torn piece of clothing and then looked back at [Y/N], a look of profound sadness in his eyes. All glitches must come to an end, he supposed, for they were pieces of code that belonged nowhere and were cast into the Void so that life may still function. And eventually they would expire and leave behind no traces of their existence, no trace of anything.

Error balled his hand into a fist, watching the red liquid seep through his fingers and puddle onto the white floor of the Void below. He sank to his knees, feeling oddly at peace, oddly at home even though he had no home. The human did not say anything, their expression unreadable. He laughed at this, so some part of [Y/N] was alive after all.

What awaited in the final life, the final realm after reality? Was there an afterlife, a place where Error would finally meet those from his dead world or was there simpky nothing, death an eternal sleep that none could wake up from? What was it like to die, to fade from existence and have none to remember you within a century's time. None would remember Error once he passed for not a single soul remained to remember his name with the exception of the human that knelt before him.

The clutches of black were swimming through his vision, black spots that grew fuzzier and fuzzier, distorting all of reality until there was nothing, nothing but the cold and dark. Nothing but -

And so the cycle turned.
