In the doodlesphere a place beyond that of even the Multiverse, Ink was hovering above the gateways to Aus as he thought to himself. 

"Where did you come from?" Ink said as he then looked at all the Aus. Ink then thought of all the talk about first Aus and nonsense like that. He knew Underfell or Underswap had to have been first, but then thought about all the times when Aus had went missing in the past. 

"What are you thinking about?" Alpha said appearing next to Ink suddenly scaring him.

"JESUS! You nearly scared my funny bone right off." Ink chuckled as Alpha floated next to him.

"So what you here for? Another fight with a evil bad guy? That Anon guy we fought before was pretty crazy or or will it be against D+ again? I really want to beat that guy; he won unfairly last time." Ink said pumped for whatever could.

"You lost that fight due to your impatience and arrogance. You could win more battles if you just focused. Stopped with the emotions you value so much." Alpha said

"..."

"Anyway, I've been listening to the abyss team again." Alpha said

"Master I told all they say is nothing, but rambling. They're simply chasing after-" 

"A ghost" Alpha said

"..."

"You've seen him and so have I, 404 isn't simply a legend anymore, that foe is real. Going around ruining these perfect universes with his "changes" and destructive motives." Alpha said

"Not only that, but hes corrupted your...rival Error." Alpha said as he then grabbed the Au known as Underswap.

"...I'm sure Error has his reasons, but that doesn't mean I can just let him do whatever he wants. I need to keep getting better!" Ink said as Alpha looked back at him smiling.

"Good, then lets get back to training." Alpha said as he teleported him and Ink to a desolate Au.

"Woah what Au is this? It's completely empty" Ink said looking around.

"I cleared it out a few hours ago." Alpha said

"WHAT WHY?! WHAT DID YOU DO TO THE INHABITAN-" but before Ink could finish Alpha shot a homing blaster at Ink sending him flying before skidding a few feet. He coiled in pain.

"There it is again, Your emotions are getting the better of you Ink. How will you face 404 with such a obvious weakness. You need to be better." Alpha said as he flew towards Ink who looked up and dodged Alpha's attack.

"Good, keep that up!" Alpha said as he continued to fight with Ink who did his best to block and defend. Alpha went for kicks and punches with Ink defending with his broom arms. Ink then punched Alpha only for it to go through his head. Alpha then grabbed Ink's arm and twisted it before throwing him to the side.

"ARAGH!...Darn it..." Ink said as he got up

"Guess I lose this one hehehe" Ink chucked as Alpha looked at him unsure on how to respond. 

"You need to learn to react faster, pace yourself and most importantly just focus." Alpha said as Ink looked down. Alpha then sighed as he then took a knee to Ink.

"Hey, You wanna draw?" Alpha asked to which Ink's eyes lit up and then got his sketch pad and other art supplies. Alpha then sat down with him and began to draw alongside him.

However on the other side of the Multiverse in Mecha!Tale, Mecha!Sans an the rest of the Abyss team now with Code!Tale Gaster as a extra guest they all stood in front of Mecha!404 who was suspended by large metal claws and having constant test run on him.

"What am I looking at gentlemen?" Code!Gaster said as he walked in with a tray of food and a cup of coffe.

"What you see is what you get. The Mainframe code running through this thing works like a damn battery. It has enough energy to power the entire Multiverse maybe even more. When we Bill helped us discover the mainframe we got enough code in it that we were able to successfully mimic 404's own power if not greatly go over it as well." Mecha!Sans said as he pointed the numbers on a holographic projection. Code!Gaster then checked a few of the diagnostics and scans.

"Tell me again, what have you had it do so far?" Code!Gaster said as he then pressed a few buttons and with that Mecha!404 was put down on the ground still deactivated. 

"The farthest we've had him fly was a distance of about 5 x 10^2,489,000,000,000,000,000 or 5 x 10^(2.5 x 10^18) light years. He managed to do that in under 40 minuets tops. We've also had it defeat countless versions of the AU entity known as Seraphim. From an Error version to even a version of Seraphim 10x stronger than that of the one we have. It's not only shown that sir, but we've also been able to have replicate creation however it is only able to create small things such as vehicles or chairs." Mecha!Sans said as he then walked over to Mecha!404 and put his hand on it's face.

"We also supplied it with nearly over five million orders each with sub-orders that allow it to go over any combative or even passive decision. It's able to detect vitals and even read vocal patterns in others to confirm truth and lies. It can read facial patterns and expressions. It's the perfect expression of life and free will and yet is still able to follow orders." Mecha!Sans said as he looked at Mecha!404.

"Perfection" Code!Gaster said as he then walked over and shined Mecha!404's metal dome.

"However we'll need a more...concreate test if we're going to be able to show this to King!Multiverse." Code!Gaster said

"What? but hes-" 

"I'm aware of what and whos hes aligned with Mecha." Code!Gaster said as he turned to him.

"Are you aware of the Au Killer?" Code!Gaster asked

"Y-Yes I am." Mecha!Sans answered

"...I'm the one who brought him back." Code!Gaster said as he drank his coffe.

"...E-Excuse me?" Mecha!Sans stuttered 

"Me and my team were looking for a way to improve our universe, to make it better. So we went looking through the Multiverse's dead ad lost code trying to find some form of holy grail. However we ended up coming across something that resembled conciseness instead, thoughts and will. I didn't know what to make of it until we decided to put it into a body.

We collected code from multiple different sansses in order to match it's own thoughts and bio-data. However when finished...we had made a crucial error. It's thoughts, it's feelings...there were aggressive and impassive to say the least. He killed my staff...my son..." Code!Gaster then stopped drinking and looked down.

"...I'm sorry" Mecha!Sans said with grief.

"It was my mistake to bring him back, now we have a chance to correct this fatal mistake." Code!Gaster said

"You must understand that its likely that our king isn't the one running the show, whoever his allegiance is to either be 404 or perhaps even that other entity. We need to start playing our cards right. If we present the head of that killer to the king he'll realize our usefulness and see us as a liable asset and maybe we'll learn some more secrets to the multiverse even you or I don't know about." Code!Gaster said with Mecha looking at him.

"...Alright, I'll have him do it. I'll activate him and then talk to Abyss on the matter for extra confirmation." Mecha!Sans said

"Atta boy." Code!Gaster said as he watched Mecha!Sans activate Mecha!404 and then leave the lab. Mecha!404 looked around before his scanners settled on Code!Gaster.

"Hello son." He said

"[Surrounding scanned and lifeforms recognized. 5 lifeforms within building structure. Awaiting orders...]" Mecha!404 said

"Soon Mecha, soon. Once your software and other appliances have been checked then we can send you out. We have an important task to send you out on that I'm sure will get us some high praise." Code!Gaster said to which then Abyss and Mecha!Sans walked inside the lab. Mecha!404 scanned Abyss.

"[Abyss!Sans from Universe#48912. Power scanning....Powerlevel...universal.]" Mecha!404's scans said as he watched them come over.

"So, we're siding with 404 now?" Abyss said annoyed

"No, we're simply playing his own game with our own rules, you see once we get rid of the AU Killer and bring him to King!Multiverse  and get in his good graces we'll become good assets to which we'll have a chance to squeeze some information out of him. Maybe even learn more about 404 himself possibly." Code!Gaster said

"Yea, but i still don't like the idea of helping him or his pawns." Abyss said

"Sometimes my boy you need to understand your enemy to beat them." Code!Gaster said as he and them looked to Mecha!404.

"I'll run diagnostics on him immediately." Mecha!Sans said as he ran over to a panel in which then deployed small drones which scanned Mecha!404 and his exoskeleton.

"His body structure is nigh-indestructible Abyss, not even thousands of big bangs combined could dent him. Not only that we calculated his speed already, its off the charts. Much faster than what we've seen 404 fly at in the past which was at best beyond that of lightspeed." Mecha!Sans said as Abyss circled Mecha!404.

"But can it beat the AU Killer though is what I'm wondering." Abyss said

"Absolutely, we've installed a unique function into his scanners which will allow him to get the bio-data of anyone hes facing allowing for him to copy their moves and perfectly asses how to counter them." Mecha!Sans said

"Hmmm" 

"I guess there no better time than now to send him then." Abyss said

"Indeed, I've already uploaded Infected's destructive pattern to his software, he'll be there before that freak will even enter the perimeter of the universe hes looking to destroy." Code!Gaster said as Mecha and Abyss both looked at him with curiosity.

"...oh its what he calls himself, Infected." Code!Gaster said.

"Well then. Guess we better get our boy on then." Abyss said.

"Deployment initiated!" Mecha!Sans said

"Alright Mecha listen up! You're going to go and defeat Infected, but i want him alive. Bring him back here apprehended and presentable to KingMultiverse." Abyss said

"[Orders understood, setting a course for the lifeform, Infected's location.]" Mecha!404 said before then shooting out of the sky roof with his rockets and flying out of the universe and traveling after Infected.
