Author Note: I have joined the dark side!
Beings- powerhouses, humans, and monsters (Sanses, Papuruses, the occasional Asgore, Toriel, etc.) from across the Multiverse gathered in a blank AU with only one goal to complete: Defeating Error the Destroyer. All in all, it seemed like a losing battle. A foolish dream to dare challenge a psychotic skeleton known to eradicate all those in his path. But it was far from that. They had planned this battle for weeks, months. Perhaps even years. Ages of coordinating, scheming, preparing, and rallying was spent with this event in mind. And now the time to take action was nigh. Everyone laid in wait, anticipating their dreaded foe's arrival. Blaster and bone attacks floated by their Sanses and Papyruses, blazing gales swarmed around the few Toriels, and tridents were firmly held by an Asgore or two. A rare Frisk and Chara stood in the background, baring a determined expression. Apparitions of various Gasters watched on. Some fearful; Others nervous and un-approving.
Each and every monster had taken their places, ready to fight (or watch from the sidelines)- Fight a battle they were destined to lose. Nothing could change that. Not even Fate. Gentle flaps of a butterfly's wings had already changed the timeline's course and forever altered the path those involved would be forced to walk.
Destiny's favored child, Error, knew something sinister was planned for him. Something concocted by Fate and the citizens of the Multiverse. They tried to hide it, keep him out of the loop. But he was no fool. Insane? Sure. Clueless at times? Definitely. A fool? Certainly not. Never. Any self-respecting Sans who trod the field of science would not be taken for a fool. Error was no different. The long-forgotten Science Sans - the one true Genocide - spotted the Multiverse's 'secret' plan from a mile away.
So, the glitch took it upon himself to counter their strike with one of his own. A strike that would shake the Multiverse to its' core, and hit Fate in their only known weakness.
During everyone's scramble to prepare, Error spent those seemingly endless months crafting his 'special attack'. Editing and changing code, mixing it with ancient magicks until he had the perfect punishment for those who wronged him. A means to pass on his duty and transform his victim into the next destroyer: His soul. (Many monsters - mainly Floweyes and the few other soulless residents of the Underground/Multiverse - proved life did not require a soul. But Error would be lying if he said it wasn't his plan to die. He craved it. Wished death would release him from his eternal suffering.) Assuming everything worked as planned, the glitched soul would transfer the powers 'bestowed' to him by Fate into a poor, unfortunate monster.
Error already had a target in mind. No other monster would suffice, or give him the justice he sought. It was- Well, a truly poetic choice.
Best of all, once his soul bound to its' new owner, it could never be removed. Any attempts to be rid of it would be met with terrible consequences- a powerful portal straight to the Void or an excruciating pain comparable to death. Fitting punishments, right? The destroyer himself was quite pleased with his work.
In the depths of the Anti-Void, Error cracked a small smile. Something subtle and sinister, not maniacal like most would assume. It was the first smile to grace his face since the beginning of Fate's little game. It made the moment feel even more special. Error would (once again) challenge Fate for his freedom. An act the powerful entity loathed. This situation very well may have been caused by his unwillingness to give up. His determination... Or, the whole 'defying fate and being trapped in the Save Screen before escaping and getting his happy ending' thing from a lifetime ago. That event angered Fate greatly but won him Destiny's interest and approval.
Yes... On this day, Error would regain his grasp on his destiny.
For eons, Fate mindlessly meddled and interfered with his existence without a care for any repercussions. But now- Now Fate's decisions would bring despair to the Multiverse; Error's revenge would be complete.
"Error!"
A voice Error had grown to loathe - more so than the ones plaguing his mind - greeted him as soon as his feet touched the stark white ground. His eye sockets narrowed at the grating noise's source: Ink. Also known as the most aggravating, ignorant, self-absorbed idiot to ever tread the Multiverse. The colorful skeleton stood at the forefront of a large army.
Perfect. Error thought to himself. That means he has no one to shield him if I attack. And they won't make a move until he orders them to... Heh. Like little puppets.
As predicted, Ink's monsters and humans waited loyally for orders. Though many looked eager to get things over with. Their hand twitching and magic itching to strike him down. However, Ink had other plans. The 'protector' of the Multiverse drew his paintbrush and aimed it toward Error, posing dramatically all the while. No doubt gaining his followers' admiration as well. Because who doesn't love a 'hero'. Charlatan. Now that was a more accurate word for Fate's soulless abomination.
Naturally, the voices choose then to give their two cents ('Well, that's rude.'; 'Don't be so dramatic.'; 'You're the real abomination.'; 'Just save everyone the trouble and let him kill you.'), but Error let Ink's little speech drown them out. Listening to them would only help prove how obnoxious they were anyways.
"This all ends now. I won't allow you to harm these people, these AUs anymore! The terror... The death... The senseless destruction... You shall spread them no longer! Today, we stand here - united - to defeat you! Today, you will die!" Ink stood tall, forever changing eyelights solid red crosshairs. Crosshairs pinned on Error.
Every visible monster cheered at the declaration. The hidden ones - Gasters, and Error noted with a hint of surprise, Death/Reaper stood alongside them - bore a grim expression. He couldn't blame them. For not interfering or preventing this battle. While many understood the importance of the Balance, a few lost souls would hardly be able to sway the majority of Multiverse. Reaper though... Error never expected to see the Death God off to the side, looking like hell froze over. But, again, he understood why. Like himself, Reaper was unpopular due to his role in the Multiverse.
Perhaps Ink would try to kill death incarnate after Error died? Perhaps all negative forces? Then the idiots would have no choice but to live in a hell of their own making.
Tyrants running around, unable to die. The old and ill and suffering unable to end their misery. Broken codes tearing AUs apart. Viruses infecting every corner of the Multiverse. Blank and unfinished universes cluttering the limited space available. Chaos and insanity plaguing the minds of both humans and monsters as their worlds lit ablaze. Now that- that is almost worth sticking around to see. Error smirked at the thought. It was the most likely outcome, too. The creator truly believed Error's role was unnecessary. He did not believe the Multiverse required the Balance. Or, his sheer stupidity prevented him from seeing that it did.
No matter. Error wanted this sick game to end regardless of any ill-effects that would befall the Multiverse.
After all, it won't be his problem once he's dead. ('Ugh! You're so depressing.'; Yes, end this. Kill yourself!'; 'Ha-ha-ha-ha! You are totally going to hell for this!'; 'Kill yourself! Kill yourself!'; 'You're just wasting everyone's time. You're too stupid to actually make this work, let alone pull it off. Give up.')
"Heh. He-heh. I h-have been try-try-trying to die for s-so long- praying for-r the swe-sweet release of-of death, tempting t-the fates t-to end me... but nothing-ing ever-ever works. T-trust me, I've tri-tried everyth-thing: Asphyxiation, electrocution, blunt force trauma-" Error went on to list his suicide methods, taking great joy in the paling of several humans and monster. Some even looked ready to puke. He continued, "And-and after everything - ev-every single fucking att-attempt to-to die - I finally-lly found something. Someth-thing that w-will free me-me from Fate's sick, twi-twi-twisted game. S-so tell m-me, Ink..."
Error stared straight into Ink's wavering eyelights. "H-how do you-you feel about becoming-ing the next destroyer?"
