((Hello!  These chapters originally belong to absolutelYin-Sane ))

(Hello! Marrow from the future here, I made this book a long time ago.  Everything here is unedited and I'll be making Chapter 3+!  Sorry, very sorry, I know I promised a Doc but I kept forgetting so I just published the story instead.  Everything else I unpublished was mine and therefore I don't feel as bad letting it become a little dustball.  It's unfair I allow something that isn't originally mine do the same.  Anyways, carry on!)

~Inks pov~

I was looking around the multiverse.  I was bored.  Very bored.  Thankfully, Error hadn't been destroying AUs much, so that is good!  I looked through a portal, but something caught my eye.  It was an apple, the apple Dream described as Nightmares apple.

I walk through the portal and pick up the apple.  I thought there wasn't any left...?  I put it in my pocket and make a portal to Sci's lab.  I walk up to the door and knock to the toon of "do you wanna build a snowman" from frozen. Sci opened the door with a smile.

"Nice to see you, Ink. What brings you here today?"

"Well, i found something.... interesting..." i take the apple out of my pocket and show it to Sci. He was so shocked His jaw could have fell to the floor.

"I-is that..... N-N-Nightmares a-apple?"

"I think so."

He takes a closer look at it, and looks up to me. "H-how did you find this?"

I shrug "i just did. It was on the floor."

"D-do you realize that with this apple, we can find out a way to fix Nightmare?"

I think for a second, but then my eyes(?) go wide. "Thats it! If we help fix Nightmare, we can bring the world to peace, or at least, mostly peace. We still have Error... But we will be half way there!"

Sci looks very excited, in fact, he almost looked like Blueberry.
"Come inside, Ink! We have a lot of stuff to do!"

I smile and walk through.
Time to start the tests.

×+ Tem skip for a few boring days!+×

I feel very relieved. Me and Sci have been working for days. But we finely have an idea on how to fix this. Sci made a potion to inject into Nightmare that will fix him.

"Well done! Lets call a meeting! To dreamtale!"
I send out a emergency text to everyone to meet me in dreamtale for a meeting.

I open a portal and walk through with Sci. Already most of the multiverse is here. Dream runs up to me and starts to ask me a million questions as to why i called an emergency meeting.

"Alright, i need us all to sit down. And calm down to, there is no threat, but this will help us all."

Dream goes to his usual seet, me and Sci walk to the table, but dont sit down.

"Alright, me and Sci think we have found a way to fix Nightmare, Dreams brother."

Dreams eyes go wide. "You have?!"

"W-well, were pretty sure we have. And its all w-with this vile."
Sci pulls out the vile that will free Nightmare of the goop that covers him.

"I-if we inject this into him, the goop that covers him should completely disappear."

"But what if it doesn't? What will happen with my brother?"

"U-u-uhh were not s-sure..."

"Is there anyway we can be sure? I want my brother back, but not if i dont know the side effects. What if its fatal?"
Dream asks. He has a point.

I think for a bit, how can we be sure....
I know! A test subject!
Maby even a project!

"I got it! What if we test it on someone first?"

Dream sighs. "But how? We dont have anyone like Nightmare."

I chuckle. "Well..... We didn't just think of this. I may or may not have found a dark apple."

"Wait what?!"

"You heard me. You want a look?" i pull out the apple. Dream along with many other people gasped.

"No.....way...."
Dream starts to smile.

"This is perfect! Now we can be sure that the vile will work!"

"Yes..... But who?"

I look around to everyone, but they all look away, or pull their hoods up.

I think some more...... Who can we have do this? What if it goes bad? We need someone not very important. So no originals...

Maby.......Error? He would say no for sure........but...i suppose we could force him? That sounds terrible, but Error is very evil, so i guess he deserves it.

"I got it. Sci, lets go. We will come back with results."

"Wait, ink, who are you going to ask?" Classic asks.

"Oh, just an old.....'friend'..."

Everyone nods.
I open a portal and walk through with Sci following closely behind.

"U-uh where are we?"

"The anti-void. Error will be out test subject.

He almost drops the vile after hearing about who were going to see.

"Dont worry. It will be ok."

~Errors pov~

I was knitting in my void. Same as usual. But i hear footsteps.
I brush it off. I assume im just going insane, i already hear voices.

But then something grabs my arms and ties them behind my back. I scream and try to turn around, but they have a steel grip on me.

I look behind me to see my enemy. Ink.
"What do you want, squid?!"

"Oh, just a test. Sci, now."

I feel something rip my sleeve.
"Hey! I worked hard on that!"

Sci is clearly afraid, but he keeps doing what he was doing. He pulls out a syringe. God i hate shots. Wait.....

"What are you doing?!"

Sci puts something into the syringe. "I-im sorry. But w-we have to do this. You will feel extreme discomfort and p-pain."

"H-hey we can talk about this.... I dont know whats in that but i dont like it..... You want me to stop destroying for a bit? I will leave the AUs alone for two....no three weeks!"

Ink rolls his eyes. "Nope. Continue, Sci."

I close my eyes. I feel something Pierce my bones, wired liquid in my bones...... Then pain... It was excruciating!
I scream in pain.

"AAAAHG NHG A AHHHH!!"
Oh god it hurts. Why does it hurt so much. I feel tears stream down my face, but they start to feel thick and painful.

I dont want to open my eyes. It hurts to much. All i do is scream. I feel a thick liquid fall down my face. I scream. But my mouth fills up with a tar like substance.
It fills my mouth to the point were i can hardly make any noise.

I feel like im choking.
I feel like im drowning.
I feel like im dying.

I finally open my eyes, but i can barely see out of my left eye. Its almost completely covered.

I look to Ink, but he looks unfazed by this. I feel weird limbs swaying behind me angrily.

But the pain dies down.
I feel hate and anger.
I look to Ink once more. I try to speak, but the goop that covers my mouth causes me unable to do so.

Ink smiles. "Dont worry. We just need to test this out on ya. It should work."

He pulls out a needle. But....
I dont WANT to go back to normal.

Ink loosens his grip. I use this as my chance. I use the extra limbs attached to my back to impale Ink. He screams in pain as i stab him more. I would laugh if my mouth wasn't covered in goop.

I hear Sci scream in fear. I haven't felt this good in years.

Ink opens a portal next to Sci.
"Run." Ink commands.

He runs out, but he drops a vile similar to the one that was injected into me. I grab it and examine it. As soon as i do, i feel Ink start to become terrified.

I show the vile to him. He trys to grab it, but i yanked it back.
He wants it so much? Not on my watch~
I crush the vile in my hands.
"NO!"

I hear another portal open. I see Nightmare walk out.

His eyes lay on me, he smiles and chuckles. "Oh wow. Is that a corrupted apple i smell?"

I shrug.

Ink takes this chance to open a portal and run through.
Nightmare walks up to me.
"Nice to see someone else like me for once, Error."

I nod. He looks at me closer.
"Can you speak?"

I shake my head. "Ah, i see."

"Y'know, we would make a fun duo. You want to come along with me to my mansion? Im sure you will enjoy it."

I was bored and i dont have a lot of things to do anyways. I nod my head. "Perfect~ follow me, Error."

Chapter two

(sorry this is short)

~Nightmares pov~

I walk Error through the portal

To my mansion, It smells like chaos.

I sigh and bust the door open causing a loud 'bang' to ring throughout the mansion.

Everyone looks at me, then to Error, then back at me.

"Well boys, we have a new member. You have already met Error, but he has had some more......... Improvements."

They all look between themselves, before Dust speaks up. "What happened to him?"

I chuckle. "Well, that's a question that only Error can answer, however, he seems to be mute for now."

Killer chuckles. "He doesn't look like an ERROR anymore. He looks more like a Nightmare now. But, you already took that name. Hey, how about you two switch?"

I roll my eye as Dust chuckles. "Yea! You two do that!"

I let out a elongated sigh. "Why do I still deal with these idiots?"

Error shrugs in response.

Cross gasps. "That's a great Idea, CC!"

Error looks strangely at Cross along with everyone else.

"CC said your new name should be Fault!"

Cross says with pride.

I look to Error, who nods in response. "I believe that would be a yes?"

Error nods again.

Cross jumps up in excitement. "YES! I DID SOMETHING GOOD FOR ONCE!"

Everyone chuckles at Cross, or at least trys.

"Well then... 'Fault' welcome to hell. I will show you your room. Follow me, I mesmerized all the halls."

Killer says while walking away, giving Error a motion to follow.

~Inks Pov~

I fall through the portal with Sci close behind. As soon as I do, everyone starts running towards us. "Oh, Oh God Ink! What happened?! Who did this?!"

Dream says, fear lacing his words.

"H-he (cough) h-h-he fought back, a-and-"

"Who fought back?!" Dream yells.

"T-the t-t-test subject f-fought b-ack."

I say, trying to stay awake. Now that I'm back here, I can feel the pain rushing through my bones.

"Error. Error was our test subject. We injected it into him, but, he attacked us before we could inject the other substance into him. He, he crushed the other vile, so we need to make more. And Nightmare came, he must've sensed all the negative energy coming off of Error, we left before we got anymore hurt."

Sci says without a studder.

"S....so now....our most dangerous enemy.... became even more dangerous?"

AlterFell Toriel asks

"......yes."

Three uwu

Wtf took me so long-

~Faults(error) pov~

It's been around a day, so far I feel great. I have my own room now, so that's cool. Now, I just need to find a way to communicate with the others. I could learn sign language, or I could just write down what I want to say.

Recently, I've been able to feel the others Emotions. It's wierd, but surprisingly entertaining. Dust seems to like me along with Cross, Killer is mostly Emotionless, so he doesn't care about me. Horror seems to fear me while Nightmare truly enjoys me. I say my favorite here is Nightmare, since the negativity that radiates off him gives me more power.

Then, there's a knock on my door, did I mention I was in my room?

Anyways, I open the door, and I'm greeted by Cross with his usual cocky grin. "Hey, Night wants you downstairs, he said he has questions for you." He says.

I nod and push past him, making him stager for a moment.

"Rude." He says under his breath.

I ignore him and keep walking.

I wasn't in the best mood, I never am anymore. So far I've only felt discomfort, anger and pleasure. Mainly anger. As I walk down the flight of stairs I can't help but look at how unkept this place is, there are cobwebs around every corner, the occasional dead rat or mouse will be on the stairs, sometimes it's still alive, somehow. Every step makes the floor creak, this place is really old. Older than Nightmare even.

I follow Nights negative energy to the throne room.

"Greetings, Fault. We have some questions you need to answer, but you probably already guessed that." He says with a dark chuckle.

Nightmare throws a note pad and a pencil at me, I catch them in my tendrils.

"We ask questions, you give answers. Remember, I'll know if you lie." he warns.

I shrug and nod.

"First question. What exactly happened that made you like this?" Nightmare asked. I start to write down the events that took place before Night showed up. How Ink injected me with that odd liquid, the pain, and the other details.

Nightmare hummed and nodded.

"How intriguing..."

"He wouldn't have done that for no reason. He was planning something, and using you as his test subject." Nightmare states.

I mean, he's probably not wrong. It's not like Ink to randomly inject me with crap that turns me into a off brand Nightmare.

"Next question. So you know everything you can do with these new powers?" Night ask. I simply write 'no. Why would I?' I'm still new to this after all.

"Fine. Final question, would you be willing to train with the idiots so you can learn your powers? They need a workout anyway." Night asks.

'sure' is all I write. It's all that needs to be said, anyways.

"Good. Get ready then. Training starts now. You'll fight the weakest to the strongest, in the end, depending on how easy it was you will either fight them all at the sane time, or fight me." he says. I nod and stand up. Let's see what I can do. 

((Okay!  So, this is absolutelYin-Sane's version, and all written of the story.  After I re-write this,  I'm going to continue the story with all my horribly amazing cannon/original glory.))
