Back in the main Multiverse Ink was resting himself and fixing his wounds in the doodlesphere.

"Damnit, I was useless that whole fight. I hope Adam is ok." Ink said as he rested himself. As he did he would suddenly get wrapped in Blue mastery, he then would get pulled out of the doodlesphere and across the entire multiverse. He kept getting pulled until he was out of the multiverse where he saw a cold and menacing 404 drenched in blood holding his hand out. Ink's throat went straight into 404's hands which he held tightly. 

"Were you aligned with the ones who took Error? Talk while you still can." 404 said

"I- I don't know anything honest! I swear!" Ink shouted to him. 404 then used his blue mastery to remove Ink's fingers off one of his hands. Ink screamed only for 404 to grab his mouth.

"This intensity is so intense. So dangerous and deadly. Yes, this is exactly what I like about you." said Malware deep in 404's mind, however 404 was so out of it that he didn't even register Malware's voice.

"T E L L  M E  T H E  T R U T H." 404 said in a even more colder tone, one Ink didn't think it was possible for him to get. 404 then used grabbed Ink's head and read his aura. He could feel Ink was telling the truth.

"Thanks for nothing you useless piece of ink." 404 said as he then used his blue mastery to stab Ink's fingers back into his hand and toss him to the side. 404 blitzed back into the multiverse shaking it upon entry. King!Multiverse was sitting on his throne as 404 landed right in front of him nearly destroying the anti-void. Core!Frisk was standing in front of King!Multiverse with fear in their eyes.

"HOLY SHIT! 404 its you." King said sweating as he saw 404 get and look at him. King saw 404 was drenched in blood and instantly began to think of the worst possible scenarios. 404 began walking towards him, he started to read King's aura and could already read the guilt coming off him.

"Tell me what you know." 404 said

"I-I...I don't know-"

"Don't you fucking lie to me. What did you do?" 404 asked as his every step made the entire multiverse shake and the spatial dimensions around it detonate. King was completely paralyzed in fear. 404 was finally face to face with King!Mutiverse, his cold gaze staring at King who sunk into his seat drenched in sweat.

"Will-" 404 then used his blue mastery and lifted up Core!Frisk with one hand and began to choke them. Core!Frisk squealed and sqirmed around.

"HEY! WHAT ARE YOU-" 

"ANSWER ME! NOW! WHILE THEY STILL HAVE SOME BREATH LEFT." 404 said as he then saw random jailed Toriel in one of the lifted cages above. He then then used his blue mastery on her atoms and caused her to instantly combust in front of everyone's eyes. King and Core looked in complete horror.

"SPEAK!" 404 shouted as he chocked Core even more, King looked at Core and then to the bloody cage, organs and body parts falling out it. His eyes then slowly went to 404 who was looking right down at him.

King was in so much shock that he just blurted out the next words out his mouth.

"The Abyss team has him." He said out of total fear. 404 then dropped Core on the ground and turned around. 

"Are you-" suddenly King's arm snapped in half to which he then began to scream in bloody murder as he collapsed to the ground clutching it. He looked up at 404 see him put his arm down. Did he snap his arm? that quickly, he'd never seen 404 move so fast. 

"Answer me when I speak to you, never forget your place as my slave. Otherwise I'll turn you into something more worthless than shit." 404 said as he then blasted off shaking the entire multiverse once again. Core caught their breath as they turned around.

"Oh god 404, whats wrong with you." Core said. However as 404 was blitzing across the multiverse, he completley snapped.

"FILTHY FUCKING CODE FRAGMENTS! YOU DARE TAKE FROM ME WHATS MIIINNNE!!!

YOU WILL RULE THE DAY!!! YOU WANTED TO TEST ME!? ME?! THE MOTHERFUCKING RULER OF THIS ENTIRE WORLD!?!!? I'LL RIP YOUR SKULLS RIGHT FROM OUT OF YOUR ASSES!!! DIGUSTING MAGGOTS!!!! I'LL KILL EVERY SINGLE ONE OF YOU FUCKING AUS IF HE ISN'T THERE WHEN I GET THERE!

NO!

SCREW THAT!

FUCK THAT!

YOUR ALL DEAAADDDD!!!" 404 screamed in bloody murder as he raced across the multiverse. Back with the Abyss team, they were all watching as Error sat in a cell.

"What the hell has been that shaking? has it taken that stupid dust that long to report back to us?" Abyss said

"I'm not sure, but something tells me it isn't good." Mecha said

"You guys! crazy shit has been going!" said V!Sans as he ran over to them.

"What is it?" Abyss asked

"A MASSIVE FUCKING ENERGY SIGNAL IS HEADING OUR WAY! Not only that, but all the spatial dimensions that surrounded this multiverse were completely annihilated in less than a instant." VSans said in fear.

"WHAT?!" Abyss and Mecha said in shock, they both looked at each other.

"You guys are so dead." Error said, he wiggled a bit in his restraints. Abyss scoffed as he pressed a button in which lowered Error's cell to a lower level.

"My god, just how pissed are you William?" Error thought to himself.

"How time do we have till it gets here? and who is it?" Abyss asked

"It's 404." V!Sans said with dread in his voice

"No way...I've only ever seen him destroy universes, that shaking is him?!" Mecha said in shock.

"And he'll be here in-" however just as V!Sans was about to say, he'd have blue mastery wrapped around him and pulled against the far wall. Abyss and Mecha looked in total shock as V!Sans beun to get squished aginst the wall, his skull become flatter and flatter has blood spurted out of his nose and eyes until the wall broke. His body would go flying to 404 who was outside their base. He grabbed V!Sans, one hand on one of his legs and the other on his neck. Abyss and Mecha looked in total terror and fear. 404 then let go of V!Sans as his blue mastery lifted him up only to the get twisted like a wet towel. The blood and bone shards falling on 404, but he didn't care. His eyes were locked onto Abyss who was frozen in total fear.

Yet 404 was dead quiet, before 404 could even make a move someone spoke.

"William! So glad you could join us!" said a voice above the base. 404 looked up and the back to them, he then flew up. He then met face to face with Null who was standing above the base seemlingly waiting for 404.

"You the boss?" 404 asked

"Yes." Null said, 404 then immediately went to attack him, but was stopped by metal tentacles coming out of the roof under him. He struggled against them as his hands were mere inches from Null.

"Sorry, but this isn't going to be going your way any longer." Null said as the tentacles then dragged him down. 404 would go through several levels of the base and be thrown onto a hard floor. He got landed on his feet and looked around, he was in a large open room. He then looked forawrd to see a completley robotic version of Nightmare, Cyber!Nightmare. He had a coded core in chest and a virtualized screen for a face. 404 stood up as he then looked behind him and saw Mecha404 standing atop a giant steal beam.

"I don't have time for this. Lets make this quick." 404 said as he got ready to fight.
