Do You Get It?

"This is how it came to be. And now I can finally show you." I say to...myself?"Error, there is no time for this!" Ink screams at me. It's weird being able to see yourself from a different point of view. It's weird to have your bodies swapped with your archenemy.But there is more to just a simple switch of bodies here. With twisted dreams of the future and out of place emotions, I can't help but realize something that shakes me to the bones. That there is something or....someone hiding in the dark. Behind the stage, they cast the cues. Writing the script. And setting up pawns, just to watch them fall on their own playing field. Someone else is pulling the strings..........(None of the artwork is mine, cause I have the drawing skills of a rock)[#1 inksans][#1 ausans][#1 forceddestroyer][#1 bodyswap][#1 errorandink][#2 undertaleau][#2 error][#10 Errorsans]

Destruction.It was what Error was good at. Destruction of timelines, AUs.Apparently, he was good at destroying himself, too.-„hEH, don'T mAKe Me lAUgh. YoU dOn'T neEd to giVE a DaMN.

Mistakes were made, but...

Cover not mine!! (Random updates..)They have known each other for a long time. They have hated each other for as long too. They fought often, they each lost and won an equal amount of times. It was a routine of theirs. Destroying Alternate Universe, fixing them, destroy, fix, again and again. There seems to be no stop. No one would dare to get in their way, no one dared to help nor did any others tried to reason with them. Until this story...

(1)Killer sans (2)error Sans x Pacifist reader

Your the pacifist daughter of blueberry and US chara. You're shy when you first meet people and you get bullied in school that cause you to be like that, also you can look at the codes from ohters you know the world you live in is like a computer plus you the guide of the 'destroyed' AU's not from every one but from inktale, errortale/coretale, dreamtale, x-tale and underfresh/freshtale. You have always cinnamon rolls and buns with you and normel sans magic but you still try to make a gasterblaster, green knifes to heal and block and doging skills like the half sans you are. I think it's a little to much nah it's fine.
