Guest: why are they only recruitin sanss? sanses. sans. Damnit

So the two started gathering only the Sans' because they knew that it was just Sans who had studied so much about the Alternate Universes, and knew they were the only ones who would understand(And tbh who really thinks any Sans would let their Papyrus fight in a giant battle like this, except Underfell?)

Hey guys! I want to thank you guys so much for reading my story, and I really hope you guys are enjoying it so far. I also want to thank you for all of your requests, and like I said, I will try my hardest to add any requested AUs into the story! Again, thank you guys so much! And I hope you enjoy!

Chapter 4; Error's Plans

US!Sans POV:

It was white in every direction. It didn't seem like there could be a ground, and yet somehow Swap could place his feet onto something solid. There were no walls as far as he knew, nor a ceiling or top of any kind. The white was blinding, and though he was always for bright things, he was getting tired of white. And blue…

He couldn't tell how long he's been like this. Maybe days, maybe weeks, or maybe just a few hours, but then again, time didn't matter or really exist there, as far as he knew. There was no time, and everything was white. Except for the stings that held him and his SOUL. Those were blue, and thin, and annoying. There was no telling how long he'd been stuck in that web of blue strings, but he could remember clearly how it happened.

He was with his brother, them two seeming to be the only ones left in Snowdin, or even in the whole underground. He didn't know what happened to the others, but he was nervous that they were hurt, or worse...

He remembered hearing that Papyrus had seen something, and told Swap to wait there while he checked it out. And while Papyrus left, Swap stayed, following the taller skeletons orders. He knew better to go against his brothers wishes, though he now wished he did break the rules instead. Maybe he wouldn't be stuck there now. Maybe he'd still be with Papyrus.

He remembered seeing something in the corner of his eye. He couldn't quite make it out but if he was correct, it looked like a…glitch of some sort. Like some form of computer glitch. And though he knew to follow Papyrus' rules, the curiosity bit him so hard he had to look, because for all he knew, it could have been Alphys, or Undyne…any other monster besides him and Papyrus. So, he walked over to where he saw it, in the corner of the labs' outer walls. Confusion wracked him, though, when he looked around over there, because there was nothing there. Well, nothing that he was able to see at first.

He looked around in multiple directions, before heading back to where Papyrus told him to wait. Though his mind stayed on whatever that was. Until he heard something from inside. It sounded like a crash, but what followed it was a groan from Papyrus. Swaps' eyes widened as worry filled him. He was about to try and call out to Papyrus, to try and see if he was okay, until something grabbed him. It was like he had turned blue, except this was so much more uncomfortable. He felt something take hold of his arms, his legs, and his SOUL. Looking at them with wide eyes, he saw blue strings, tied tightly around his bones. Then came a tug, a yank, making him fall flat on his ribs. More tugging, be couldn't tell where he was being tugged to, too much panic seeping into his bones. He tried to call for Papyrus, seeing him turn around. More tugging, ore dragging. He heard Papyrus call out to him. But then another sound. It sounded like a glitched laugh. It sounded almost similar to Swap, but it was a bit deeper, and it couldn't keep a straight tone. He saw Papyrus running towards him, but then, white…white everywhere. He tried calling out to Papyrus, scared half to heath about what was happening.

He was stuck there for a while, unable to do anything, not even move. Those strings held him tight, refusing to let go. He remembered seeing something before. Those little error that looked like what would come from a broken computer.

Then came another nerve wracking, glitched laugh. Swap couldn't tell where it was coming from, it echoed all around. Dark and definitely not friendly like, he could tell that much. But the next time he looked around, that's when he saw him.

He didn't mean, a different person him, no. He meant, another actual him! Only, he looked, so different. This… other him, looked like the person who would have given off that laugh. Swap knew it was him instantly. He was pure black, but was glitching all over. His right eye drooped it didn't look like it wanted to stay open, while the other looked like it was working perfectly fine. Though coming from both eyes, it looked like permanent tear streaks of bright blue, the same color of the strings that held Swap tightly in place. His jacket, too, was the same color. A black, or maybe just a really dark blue that looked black. He wore a red shirt underneath it, and his hands looked a little like they had gloves on, as they had red and yellow on them. His teeth and eyes were a dark yellow, and his left eye, where Swaps eye would be blue, was a dark red mixed with a bit of black. He wore a smile, but it held not even the slightest bit of kindness. It was a comedic smile, for sure, but it also held an evil glint.

The other him didn't speak for the moment, he simple stared, observing with that nerve wrecking smile. Swap could feel this…Error version of him looking right through him. And soon he couldn't stand the silence.

"W…who are you? What's going on? Where am I?" Swap kept his voice low and soft, feeling afraid of speaking too loudly. The ErrorSans stayed silent for another moment, but Swap could see his grin grow wider, and another nerve wracking chuckle came from him.

Error POV;

Error stood, observing his new puppet, the smile on his face growing wider as he heard Swap speak up. He laughed, his voice glitching slightly as he did, but he didn't care about how it sounded. He actually enjoyed it, because it always seemed to frighten the other skeleton. And he loved the look it brought onto Swaps face.

"heh…common, you can't figure out who I am yet? Heh…" He laughed again, rather chuckled, instead, and looked back up at the tangled skeleton.

"Call me Error…" His voice glitched at his name, and smile widened again at Swaps look. Another moment of silence, and Swap spoke up again, his voice giving a slight quiver.

"What's going on..? Where are we? Why are we here?"

"Heh…" Another chuckle from Error, and he looked back up at Swap.

"Welcome to the Antivoid. I brought you here for a little fun…" Fear flashed Swaps face again and Error took in the sight of it before continuing.

"I've been here for a long time, taking out the unneeded errors and abominations that you errors call alternate universes…" He paused for a moment, allowing it to sink into Swaps skull before continuing.

"Unfortunately, as I have so much work, cleaning up these messes, I thought that it was getting kind of annoying. Each AU I destroy, gets replaced by a new one. Though my task is indeed enjoyable, it's gotten to be quite,,, boring. So, I've decided to try something…new."

"W…what do you mean?" He could hear obvious confusion in Swaps voice, and Error turned to face away from him. He lifted his hand above him, and what looked like a screen popped up. Error smiled at the sound Swap made, seeing his brother on the screen, working hard, surrounded by other Sans'.

"You see…You seemed to be the easiest abomination that I could get my hands on. So after taking out most of your universe, I took you, leaving hints for your bro that I was there. He seems to be doing well with his part of the game."

"What game..?" the next question came out even quieter, and he could feel Swap shaking slightly within the tangle of blue strings.

"Well, I've decided to switch things up a bit. I'm a bit tired of having things go the same way every time. Everything is too easy now. So easy to destroy an AU without anyone realizing what would hit them. I needed a real challenge. So…I figured, a fight, brother against brothers would be the most entertaining way of finishing off even more abominations at once."

He felt Swap stiffen again, but he was too busy enjoying the sight on the screen. The taller skeleton on the screen was talking with multiple other Sans', Classic, Science, and Fell. Surrounded them were multiple other Sans'. OuterTale, StoryShift, G!Sans, and a few others he didn't care about naming, seeing how they were all just glitches to him. All just abominations. He watched as days passed on the screen in mere minutes, and one my one another Sans was working with them on the screen. Time didn't really exist in the Antivoid, which was why he could see everything go by so fast. He knew the day of the fight would come quickly, and he was ready for it. Taking one final look over the screen, he swiped his hand in the air and it disappeared. He turned back to Swap, his grin never faltering as he watched his stiff form.

"I hope you're ready, puppet. Because our fun is only just beginning." He laughed out before teleporting out of sight, leaving Swap alone in the white empty space, all by himself.

? POV;

"…" He stood, staring at the scene before him, his mouth tugged in a tight frown while his fists clenched ever so slightly. His work pushed aside, he spoke soft to himself. His voice quiet, yet loud enough for himself to hear it.

"…this isn't right…"

Heya guys! I'm sorry that this chapter took so long to upload, and I'm also sorry for it being so short. But I figured you guys would want to see a bit of Error and Swap, and see what the plan is! Please leave a review if you'd like, and if any of you guys are interested in making a request for a certain AU, Just tell me in the reviews! Thanks a bunch guys! And I will hopefully see you soon!
