This story is also - and started - on Wattpad. It's also in AO3. It belongs to me.

In this story, Error remembers nothing of his past world or about a lot in general. I think the reason Error became the Destroyer is because he remembered his world and hated how their were Monster's he knew, but looked and acted different. It would be like torture to him, to see faces he loves only to be twisted into something unfamiliar. In this story he only remembers the Anti-Void. He has forgotten basic living as well, like what food is, how to eat, and what magic or a soul is. It's not like the Anti-Void is bursting with life. Error knows he can do things, like make his string, but doesn't know why he can do it and how it is possible. He only knows what the Voices has told him. He never made a portal yet, so he has never left. Stuck for god knows long with only the Voices to keep him company. Error, in this story, is mostly confused and excited when he finally opens a portal to a AU.

Fresh has taken Error's place in this story, become known as the Corrupter instead of the Destroyer. He can feel some emotions already, but not the happy ones. After some time Fresh becomes enraged and jealous that these other Monsters can be happy, while he can't. So he decides he can do something about that. Fresh still possess other Sans's, but he doesn't stop there. He turns the whole underground, like say Undertale, into a UnderFresh. The characters and the world around them turning into fresh versions of themselves. But the coding in the worlds are not made for that and can not handle being turned into something it's not meant to be, the coding itself becomes twisted and corrupted. So the World that Fresh corrupted eventually crumbles and destroys itself.

Ink, of course, hates this and tries to fight him to stop him. Fresh thinks that's amusing at most and eggs Ink on. Fresh doesn't mind there being more AU's, after all more worlds mean more possessing and corruption of course. He just hates that they can feel light and happy, while he can't. Fresh, when he finally feels love and happiness, refuses to let it go and will do whatever it takes to keep it. So yes, Fresh will be slightly yandere in later chapters. It may take a while though for that to come into play.

Every Universe has more then one world, or timeline, with little differences. Like if I write UnderSwap-14, that means UnderSwap World, timeline, and/or Dimension 14. Whatever you want to take it as. UnderSwap-Prime will be the original, or first, UnderSwap. Differences could include a less innocent Blueberry, or even little things like the building are different, or different choices were made. Like genocide, neutral, or pacifist choices. I'm doing this so I have more options later, if I destroy a world, but want to go back to it or use a character, I can. Also because I can see Ink giving in to Fresh's vicious teasing and decides to make more worlds, thinking its for the best, in retaliation, or even just trying to make things better in his own way.

I hope I explained everything clearly so no one gets confused later on why they are acting like they are. With all this out of the way, we can finally begin the story!

-Chapter Start-

White.

There was nothing but white as far as the eye could see. White walls, white floors, and a white ceiling. Error's shocked he hasn't gone blind yet from only ever seeing white. He would say he hated the color, but he doesn't know what other colors look like.

Error was laying down, looking around with blank eyes. Having nothing to do but wonder and sleep. And doing nothing but sleep has lost it's luster. So wondering it was!

'I wonder what other colors look like...Are they pretty? Or ugly?'

Ugly, just like you.

Now, now, it's not like he will ever see them.

Yeah! He's too weak!

"ShUT-uP..." Error grumbled weakly to The Voices, it was always the same. He slowly stood up from where he was laying. There was nothing to do but sleep and play with his string. How long has he slept? An hour? Days? Months? years?! Error had no clue and soon stopped caring, not like time mattered here. 'How long have I been here?'

Error shook his head. No use in wondering, not like he's ever been anywhere else. The white walls and The Voices are all he's ever known. All there ever will be.

So weak.

You will just give in?

Pathetic!

"whAt eLSe IS tHEre!?" Error yelled out into the nothingness. This was not the first time they had this argument. "iTs NOt lIKE i CAn lEAVe! aND EvEN iF I couLD, WHeRe cAn I gO?!" Error gestured around with his hands, showing that there was nothing around. "ThIS iS aLl tHeRE Is!" Error paused, thinking about it for a moment. He actually never asked them if there was anything else. Error just assumed that after all his searching for a way out that this was all there was. "ThIS Is alL THeRe IS...RIgHt?"

hahaHAHHAHAH!

You truly don't know!?

No it isn't, you fool.

Error felt like he was struck. 'There is more then this?' Error looked around wildly, trying to see a way out that he somehow missed. "I cAN lEaVe!?"

How can you?

Why would you want to!?

You will just die out there.

"OH, NoW yOU woN't tElL mE!" Error felt tears starting to form. This was the first time The Voices gave conformation on there being something more then this. He has forgotten what hope felt like. Error lost that feeling a long time ago. He has a chance to see beyond the white, a chance to see colors. He knew he was a different color then white, but the Voices would never tell him what colors he had. They only told him about the White. 'They knew it would only make me happy to know more then these white walls!'

'I have a chance to see other people...'

Error couldn't breath. He wanted to know, wanted to learn and understand whatever is outside. He wanted to see anything but white. Even if the Voices are right and it will just get him killed in the end, it would be worth it in his eye. Now the main question, how can he leave?

"TelL mE hOW!" When in doubt, even if they hated you, go to the people you know. Not like he had anybody else to ask (Read: demand).

Why should I?!

It is fun watching you struggle.

You will never leave~

Error clinched his eyes shut in frustration. His breathing quickening as he felt something inside of him build up. 'Why do they always do this to me!?'

"I wIlL lEaVe!" Error growled as he pulled out his string in anger, ignoring the Voices mocking laughter. "i WiLL seE whAt iS bEyoNd!" Error could feel his tears falling. Error started stomping his feet, trying to let out all his frustrations.

Awww~! Look the baby is mad~

HA! Worthless like always.

Hilarious! I didn't know you made jokes!

Error started glitching out as he tried to hold back his anger and confusion. The pressure inside of him continued to grow with his anger. 'What is happening?!' Error started to yank at his hood in panic.

"ARhRaHhHAR!" Error's glitched out scream echoed all around as whatever was building up inside him exploded! Magic came to life all around him. Error swiped his hand around in panic, not understanding what was going on. The magic swirling all around him stilled, his strings warping with the magic when it was thrown. Then a crack formed in mid-air.

What are you doing!?

Idiot!

This is not going to end well.

Error panted as he fell to his knees. 'What just happened!?' Error looked to where he flung his hand, seeing something growing in mid-air. It slowly started to open, cold air soon blew in.

"oH!" Error gasped in excitement.

Error stumbled as he hurried to were the now hole was. Error's eyes glittered with excitement as he got closer. He stopped a foot away, looking it up and down with eager eyes. He could feel his bones rattling with interception. Error slowly inched closer, peeking to look inside.

Big doors! And such a weird color! Smells and sights Error had never experienced before was now in font of his eyes. Error's eyes widen as he rubbed his hands together. There were so many different colors, even if he could still see some white in there, things he has never seen before within his reach!

"HoW iS tHis PoSsIbLe..?" Error questioned as he took a step closer.

'This is it!' Error gulped as he stared at it in wonder. He could leave. He had no idea how he did it, but he did! Error shivered as the cold air hit him, he tugged at his hood to make sure it would stay around his skull.

You will regret this!

Nothing will ever be the same after this.

You will feel great pain!

Error frowned at the Voices as his patience snapped. "i dOn'T CAre!" And with that he all but flung himself into the hole. The glitched hole soon closing behind him, leaving nothing behind in the Anti-Void.

It is a shame that the Voices were right in the end.

Nothing will ever be the same after this, for anybody.

-Chapter End-

I hope this came out well. This idea just wouldn't leave me alone! If there positions were swapped, but they still kept most of there personality. Error still is Error, not Reboot. He is just more confused, naive, and can be scared more easily. Just like Fresh is the same, hating cussing and loving everything about the 90's. Fresh is just more prone to violence, being able to feel some emotions already, and doing some extreme things (Like killing a whole world). Just a few different dissensions or things happening differently in the past, creating a different present then the one were used to. It's like that saying 'A butterfly flapping in a different country can cause a hurricane.'. Error not leaving in till way later has caused a huge hurricane.
