In HQ Error was looking around for 404. He even began to use his own scanner to track where he had been only to then turn around and see 404 hop out of the Mainframe. He was severely battered and bruised.

"Sir!, Damn you look like shit. What happened?" Error asked

"...Loading, Happened. Whats going on?" 404 asked as he regenerated his arm and his ribs and took off his jacket, Error need to take a minute to look at 404. He was everything he thought he was before they met. Strong, independent, charismatic and yet also colder than space itself. Yet he was none of those things now, but if 404 has taught him anything. Its that anyone can improve. He then shook his head and focused again.

"Sir, theres a metal version of you! A Robot!404!" Error said

"Oh? I'm flattered." 404 said

"Sir this is serious! It kidnapped Nightmare." Error said, 404 then looked back with a confused look with Error then also thinking about what he just said.

"Ok maybe thats not important, but that robotic version of yourself is. I could sense your own power coming from it. No doubt this has something to do with the abyss team." Error said as 404 then recreated his old digs(Navy blue design). He cracked his knuckles and then turned around to Error.

"Hmm, yea I can feel it, its like theres another me flying around...this is interesting. Hmm kinda reminds me of my fight with Ares way back when. Still bizarre to think about. This really sucks though, if only I could be that strong on my own." 404 said scratching his skull.

"You aren't alone." Error said, 404 and Error looked at each other. They both soon wore determined faces with 404's having a hint of admiration. Error had come so far, he was everything 404 wished he was before. Error had shown true promise. Somewhere deep inside his soul he even felt like a proud father to Error. 

"Thanks G, I don't think I could have managed this far without you." 404 said, Error looked at him almost surprised before cracking a smile.

"Yea well I know that." Error smirked as he secretly was feeling a emotion greater than joy.

"Alright then, lets go out and-" however before 404 could finish a giant blue question appeared above them, so big it made the two look like ants.

"What the hell is that?!" Error shouted

"I'm...not sure." 404 said as then a group of people came falling down out of the mysterious questions mark, it was D+, Another!Sans, Supreme!Sans and even Code!Gaster who would all land a few feet away from 404 and Error who were now on guard more than ever.

"WHO THE HELL ARE YOU!" Error shouted when he then met eyes with D+ who he knew very well. Supreme stood up and stretched a bit before doing a flip and finally landing on his feet...before doing another backflip.

"ALRIGHT! Enough fucking flips." D+ said to which Supreme just shrugged. 

"I'm guessing your here for me?" 404 asked

"Your smarter than you look, which i mean with a outfit like must be hard." D+ said

"I'm not talking to you banana brains, I'm talking to your obvious boss." 404 said, Supreme than burst into laughter until D+ looked at him to which he stopped and just smiled.

"That would indeed be me, you already know why I'm here. Your reign over the multiverse ends this day. Now you have two options, one is-"

"SHUT UP!" Error shouted

"Not really one of the options, but ok." Code!Gaster said

"You have only one option and thats dying!" Error shouted

"Man who invited the baby." Supreme said

"What did you call me mr-"

"Error, I got it." 404 said as he walked forward.

"Your student is right, better to pack it up. Cause your not walking away from this with all your limbs in tact." Code!Gaster said, thats when D+ began to shake his arms and Supreme got to cracking his neck and knuckles.

"Theres no need for violence, just come along quietly and there won't be any problems." Another!Sans said

"Not happening." 404 said

"I was hoping you'd say that." D+ said

"Fair enough, lets see just how good the God of the multiverse really is." Code!Gaster said as he snapped his fingers and suddenly two quick bolts of blue lightening would come shooting out of the large question mark above them hitting both 404 and Error. Error would get knocked out immediately, but 404 would endure it. He looked down to see Error unconcise on the ground.

"Awww poor baby, guess he ain't all you trained him to be huh?" said D+, 404 looked to him annoyed. Thats when he noticed his arms were shaking.

"Can't make the weak strong mate, you gotta be born that way." Supreme said

"Then prove it." 404 said

"Now guys-" however before Another!Sans could say anything D+ and Supreme immediately ran towards 404 and began to fight him much to Another's disliking.

D+ jumped up and threw multiple punches with 404 dodging them and kicking a bone out of the ground knocking D+ back, he then jumped backwards as Supreme went to kick him in the gut. D+ then regained his footing and ran back into the fight and fired three blasters causing a massive cloud of dust. 404 looked around him knowing he didn't have time to set his eyes to see through it. 404 then created a portal beneath him to a random Au, he jumped into it and would land in an alleyway. He looked around only to have D+ jump down and punch his head into the ground and move at the way or Supreme to stomp it further in. D+ then grabbed 404 by his coat and pinned him against the wall. 404 used blue mastery to push both of them into the building behind them which just so happened to be grillbys.

"Agh! This guy isn't half bad." Supreme said as D+ helped him.

"You haven't seen shit yet." D+ said as he then blocked a god ray from 404 by using a random customer inside the bar which killed them instantly. 404 then flew in and close-lined Supreme and would fling him out the front window with his blue mastery.

"Just you and me blue boy." D+ said as he then dodged one of 404's god ray's point blank and then punched 404 so hard in the face he went flying out of his shoes and would go stumbling into a booth. 404 got up but not before he then spit out a tooth. Thats when they heard a giant thud come from the alley they came from. D+ turned around then dodged a machine gun of blue bullets that then hit 404 pinning him to the wall. Mecha!404 then came flying out of the hole in the wall and would turn his right arm into a hammer and smash it against 404's head and then smash his skull against a table.

"HEY! YOU BUCKET OF SHIT! YOU ALMOST HIT ME!" D+ said, 404 then kicked Mecha!404 in head sending it teetering back a bit as he got up. 404 then tore off his ruined jacket.

"So...there really is a robot lookalike of me. Freaky." 404 said. D+ then rushed him and began throwing punches at 404 which he dodged, 404 then took a swing and punched two teeth out of D+'s mouth with D+ then retaliating with a swift sucker punch to the jaw and 404 hitting back with summoning a blaster from the sky and having it drop right on top of D+. Mecha!404 then combined both his arms into a giant cannon and fired the large blast destroying the blaster and knocking D+ and 404 out of the bar sending them flying into the library next-door. 404 went flying into a bookshelf. Mecha!404 then pinned him against it as it fired a barrage of punches faster than light speed all over 404's body until then kicking his head and knocking him threw it.

Outside Supreme would get up and shake himself off. He then heard the commotion from inside the library. He shook himself off and then looked around and looked at the large Christmas tree in the middle of snowdin. Back inside Mecha!404 would go flying backwards with 404 then pinning him to the ground with his blue mastery, 404 blitzed over and landed some quick and precise blows to his head denting Mecha!404's metal skull however Mecah!404 then turned on his rockets and flew upwards smashing himself and 404 against the ceiling. D+ then woke up and stood up straight as he spit out another tooth. He then saw Mecha!404 an 404 duking it out.

"HEY! YOU HIT ME AGAIN METAL BRAIN! I'M ON YOUR SIDE! Piece of cheap hardware! Hit me again and you'll be the next thing on my shit list." D+ said as he then ran in and jumped up wrapping his legs around 404's head and then slamming him to the ground with a large thud that shattered all the windows in the building. D+ then turned 404 over to which 404 then fired consecutive god rays at D+ who once again dodged them point blank and kicked 404 in the jaw nearly breaking his neck. He then grabbed 404 by his legs and swung him across the room for Mecha!404 to punch his head through a wall and into a broom closet. Mecha!404 then grabbed 404 by his legs only for 404 to kick Mecha!404 so hard in the jaw his head would go flying right off. D+ looked in surprise, however not as much surprise as when the robot continued to fight. Even without its head Mecha!404 grabbed at 404's legs and then pulled him out of the closet and swung him towards the opposite wall to which it then fired its god cannon which 404 dodged. The blast was so quick and fast it destroyed a whole other galaxy after leaving the planet's atmosphere. D+ then punched 404 in the face once again and followed it with multiple body shots and shots to the head with 404 unable to retaliate or hit him back.

404's eyes looked around the room and then remembered some of what D+ had said earlier and with that in mind used his blue mastery to pull Mecha!404 towards them crashing them back into grillby's. D+ landed on his face and spat out some blood with 404 doing the same as he leaned against the bar counter. 

"Stupid...fucking...robot!" D+ shouted as he then blitzed around and tried to punch Mecha!404 only to remember he didn't have a head and completely miss allowing 404 to fire a god ray at him and paralyze him. However out of nowhere Mecha!404's would come blasting through a wall and smashing into 404's head causing him to face plant right into a table. 404 turned his head to see Mecha!404's head screw itself back on and completely reattach itself. It then pushed D+ out of the way and through a wall to the outside and into the library as it made it's way to 404. However 404 would hear rummaging outside and would move out of the way as a large tree went flying through the bar and kocking Mecha!404 into the back alleyway of the bar. 404 then looked at where it came from only to get a swift kick in the face from Supreme who the begn to continue to kick 404 in the face and then finally uppercut him behind the counter. Supreme hopped up onto the counter only for 404 to sweep his legs with his arm causing him to fall over, 404 then kicked through the counter an sent Supreme flying outside once again. 404 dropped to one knee as spools of blood leaked from his face.

"mother...fuckers...that hurt. Since when did these stupid sansses get so strong." 404 said as he got up only to get clocked in the face from D+ out of nowhere and get sent right out into the ally they came from when the fight started. D+ followed and kicked a trashcan at 404's legs tripping him, D+ then skid over and began to stomp on 404's head, thats when a large blast would fire and nearly hit D+ yet send 404 flying into the open. Mecha!404 then would go flying after him, however it's momentum would be stopped and as it looked behind it would see D+ who had grabbed his leg.

"Told your metal ass to stop hitting my ass." D+ said as he then fired two bones through Mecha!404's legs destroying it's rockets and then would swing Mecha!404 into the bar causing it to crash into a random booth. 404 slowly crawled up only to get tackled by Supreme to which 404 got out of and then would throw into a line of trees. He then used his blue mastery to drop all of them on top of Supreme. 404 huffed and puffed as he fell to one knee. He then heard crunching as he then saw D+ walk out of the alley and towards as he spit blood out of his mouth.
