In the Rainbow Factory...

"The hair would be great. Starting out with something more painful than what you did to me in the fanfic."

Damn it, Dash! You weren't supposed to mention that!

Ah, shit. There I go again.

"Th-WHAT?!?!" Pinkie Pie screeched.

"Yes, that's right."
Something fell on top of the cages and made a loud clank.

"What the- where did these come from?"

"I don't know why there are chains, but anyway. I put cloths around the cages so they would want to see what you're doing. Raise the suspense."
"That REALLY wasn't necessary, but whatever."

Rainbow Dash grabbed something from the cart and turned her attention back to Pinkie Pie.

"This is going to be fun."

She grabbed Pinkie's hair and yanked it up. Pinkie winced as the metal strap around her neck applied pressure and dug into her skin. Rainbow pulled even harder and wrapped Pinkie's hair around the pole. She yanked as hard as she could and tore off a bit of hair along with the flesh around it. Pinkie Pie tried to pull herself back onto the table, but it just caused more hair to rip off. Pinkie Pie stopped as a tear streaked down her cheek. Rainbow Dash pulled Pinkie's hair even harder. Blood ran down Pinkie's neck and onto the table. Pinkie Pie gritted her teeth as tears continued to streak down her face. Rainbow grinned and grabbed a knife. She pulled on Pinkie's hair and swiftly cut her scalp off. Pinkie screamed in agony as her blood streaked down her head.

"Dashie! Stop!" She cried.

"Why should I? This is so much fun."

Rainbow Dash ran the knife down Pinkie's chest. Blood leaked out and she stabbed the knife through Pinkie's stomach and flicked the knife up. A trail of blood followed and Dash tore her open. Pinkie screamed as blood continued to run down her face. Rainbow Dash grabbed a nail and slammed it into Pinkie Pie's cutie mark. Pinkie Pie was losing consciousness but Rainbow injected something into her to keep her awake. She took another nail and took the time to dig it into Pinkie's flank. Pinkie Pie gritted her teeth and prayed for the torture to be over soon.

"D-da-sh... p-please..."
"Oh my gosh please stop!" Rainbow mocked. She laughed at her terrible Pinkie Pie impression and at Pinkie.

"Come on! I'm not even halfway done with you and you already want me to stop. Why should I? You didn't stop when I said to stop in th-"

DON'T DO IT AGAIN!!!
I'm never gonna stop with that, am I?
Just pretend that never happened and don't mention the fanfic again!

"B-but Dashie! You know I would never do that to you!"
"Save your excuses. I don't wanna hear them."
"But-"
Rainbow Dash grabbed another pole and forced Pinkie's mouth open. She shoved it in and broke a tooth. Blood began to spew out and Rainbow cut out her tongue. Pinkie attempted to scream, but only gurgled blood.

"Heh. Have fun gurgling your own blood and swallowing that tooth of yours. With your mouth open."
Pinkie Pie pulled on the metal straps, trying to get out, but it was no use. Pinkie turned her head and the blood in her mouth poured onto the table. The tooth came out and Pinkie Pie tried to spit out the rest. Rainbow Dash grabbed one of Pinkie's kidneys and pulled it out. Pinkie was able to scream through the blood still in her mouth.

"Alright. Let's see. We have this part..."
Rainbow pointed to Pinkie's insides.

"...We have the face and the hooves. Which one should we do first?"
PInkie begged for her to stop, but through the blood still flowing out of her mouth, all anyone heard was gurgles. Rainbow Dash turned around as she heard sobs.

"It's alright, sugarcube. I hope she'll realize what she's doing soon. She'll regret this."
Rainbow Dash raised her head and scowled at the cage.

"I know what I'm doing. And I will never regret it." She said. She turned her attention back to Pinkie Pie and grabbed an ax.

"What the... this wasn't here before... whatever."
She raised it above her head and slammed it down onto Pinkie's back left hoof. It shattered the bone and hit the table with a loud BANG! Pinkie Pie screamed as blood spewed out of the cut and onto Rainbow Dash and the table.

"Okay. THAT was awesome."
She took the ax and slammed it down on the other back hoof. More blood covered the insane pegasus as she dropped the ax on the floor.

"I never thought killing my victims myself was so much more fun!"
Rainbow Dash bit a piece of exposed flesh and ripped it off. She punched Pinkie in the stomach and chuckled.

"Dash! Are you INSANE!?" Twilight yelled. She had managed to tear off a bit of the cloth and watch what was happening.

"Of course I am! Why do you think I'm the manager of a pony killing factory?"

"WHAT!?!?" The four other ponies screeched. Pinkie managed to get the rest of the blood out of her mouth but it was now filling up again.
Rainbow threw a knife at Rarity and Applejack's cage. It ripped the cloth, went through the cage bars, and nearly hit Rarity. Rarity shrieked and hugged Applejack.

"Now shut up. I gotta finish this bitch here."

Rainbow Dash grabbed Pinkie Pie's head and jerked it up. She spread her wings and hovered above the table, pulling on Pinkie's head. The metal strap dug into the earth pony's skin and blood began to leak out. She kicked the side of Pinkie's face and stomped a hoof on the side of her face. The pole fell out of Pinkie's moth and knocked out two more teeth.

"D-ashie! S-top!"
"Why? Give me one good reason!"
"I'm your friend!"
"YOU ALL BETRAYED ME!!!"
Rainbow ripped her other kidney out and shoved it into Pinkie's mouth. Pinkie gagged and attempted to get the oragan out of her mouth.

"Shut up. You talk too much."
Pinkie Pie turned her head to the side so she wouldn't have to look at Dash.

"Aw. What's wrong? You want this to end right now? I can do that!"
"H-how?"
"Would you prefer to be grinded, decapitated, or have your neck snapped?"
"WHAT?!?!" Rarity screamed.
"Neither! Just let me goooo!"
Rainbow Dash rolled her eyes and got up in Pinkie's face.

"You said that you wanted it to end now. So tell me, do you want this to end now or go on with the torture?"
"I... want it to end now. B-"
"How the hell do you want to die?"
"..."
"Atmosphere? You said you wanted to try a non-pegasus in the device, right?"
"Yeah."
"Well, this could be our chance. You can't walk so we could just throw you in. That sound good?"
"..."
"Since you won't answer, I'm taking that as a yes."
Rainbow Dash unstrapped Pinkie Pie from the table and yanked the earth pony up. She grabbed her by the head and flew up above the Pegasus Device.

"You can start it, Hide."
"But-"
"This might be the ONLY time I trust you with this. You know how to operate it."

Dr. Atmosphere nodded and flew down to the control panel. He pressed a few buttons and the machine awoke with a small crunch. Rainbow Dash smiled and looked in Pinkie Pie's eyes for the last time before grabbing her tail and pushing down on her flank as hard as she could. The pink poofy tail disconnected and Pinkie Pie fell into the great maul of the machine. It grinded her up, bone by bone until nothing was left. Rainbow Dash quickly took over at the control panel. Instead of pink spectra, red spectra began to spew out of the hoses. Nopony said a word in a long time.

"Rarity." The broken horn unicorn instantly turned her attention away. "You're next."
