ONE WEEK LATER
For the last seven days, Skyfire locked herself in he house. It's not like she hasn't done it before, but this time was different. She was unsure if this was real life...she was unsure if that mutation would flare up again. She tried to be as calm as possible and sleep so she wouldn't think of her horrible thoughts.
Skyfire was laying on her bed, and looked over at the book she borrowed from Twilight. She should probably give it back to the unicorn.
"Let's see if she can answer some questions," Skyfire thought.
Off, again, Skfire went to Twilight's treehouse. She knocked on the door and was confronted by Twilight yet again.
"Ah, Skyfire. Hello. Your mane is a little..." Twilight drifted off.
Skyfire looked at her mane that was flowing down the side of her head. It was ruffled and hairs were sticking out everywhere. "Yea, bedhead, I should probably fix that."
Twilight's horn glowed as she fixed the white pony's hair. "There you go. So, you here to return the book?"
"Yes, but I also have a question about one of these mutations." Skfire opened the book and grabbed the loose-leaf paper that held the mysterious mutation.
"Oh, I see you found that. I was supposed to throw that page out. What questions did you have about it?"
"Is this a real mutation?" Skyfire asked.
Twilight paused. "Eh, well...It's believed to be a myth. Everybody says it's just an old filly's tale. I'm guessing you'd want to hear the story behind it?"
Skyfire nodded.
"Well," Twilight began, "This mutation is said to be the rarest of them all. It's said that every 1,000 years, a special pony is born with it. There's only a few written accounts of it, and some ponies say that their ancestors have seen it. Of course, it's an almost impossible mutation, I have no clue how it could happen-"
Twilight stopped in the middle of her sentence and stared at Skyfire.
"What's the matter Twilight?" asked Skyfire, confused.
"Ev-Every account of that mutation invovled a pony with white fur and a mane like fire." said Twilight.
Skyfire and Twilight sat there, staring at each other. Skyfire's mouth was wide open.
"But, I guess it's just coincidence. I'll just take that and transfer it," said Twilight, coming out of her trance.
"Wait!" Skfire yelped, "You don't know the real reason why I wanted that book."
"And why was that? ...Wait, what are you doing?" asked Twilight as Skyfire closed the door and shut all of the blinds.
"Do you have any spells that can change mood?" asked Skyfire. Twilight was becoming confused.
"Well, I was working on a few spells related to emotion..."
"Use one to make me mad," said Skyfire in a rushed tone.
"I'm not sure that could be-"
"JUST DO IT!" shouted Skyfire.
Twilight thought for a few seconds, then her horn began to glow. This wasn't a normal glow, thought. The glow covered the whole horn and began to grow and get brighter. A beam shot from Twilight's horn onto Skyfire's head, and spell was over.
Skyfire was on the ground with her eyes closed. She got up off of her stomache and turned to face Twilight.
"So, Skyfire, did it work? Or did it jus-"
Skyfire opened her eyes. They were a flaming neon green, just like in the woods. Twilight stepped back in horror, but also in awe, as the white pony's fur began to contort.
"Skyfire, WHAT'S HAPPENING???!!" shouted Twilight.
"Now you know..." said Skyfire, her vice slowly creating a digital tone behind it, "Why I needed...that...BOOK!!!! AHHHH!!!"
Metal plates began emerging from her fur again until they covered the pony. Her mane and tail began to catch on fire. Skyfire began to feel fear, she remembered what happened last time.
Again, her mane began to flare even bigger. She prepared for the worst. But, a fast as it flared up, her mane settled down, and her fiery mane and tail were burning in a controlled fashion. Skyfire's body had accepted the sudden mutation, and a metal pony was standing in front of Twilight Sparkle.
Twilight stood in awe.
Skyfire was looking directly at Twilight. "Twilight, what am I?" she asked in her semi-digital voice, scared.
"So that wasn't a filly's tale after all..." said Twilight, feeling ashamed.
"You cannot tell anybody, Twilight. Not yet."
"I agree. Everybody would panic."
Skyfire began to walk around the library, her metal hooves clanging against the wooden floor. "That explosion in the Everfree Forest. That was me. I was angry because my father had been shot. It was the first time I had experienced...this shape shift, or whatever you want to call it. My body couldn't handle it and became unstable."
"This is....amazing...." said Twilight, looking closely at Skyfire's metal body. "It seems to be some type of bio-mechanical metal."
Skyfire started admiring her body as well. She was amazed at how this was happening. "Now, how do I get out of this form?"
"Hmm...Well, I guess you can try to calm yourself down. Maybe that will reverse the effects."
So Skyfire sat down and took a deep breath. Her mane and tail's fire was dimming away, revealing her real hair again. The metal plates shifted back inside Skyfire's skin, and her eyes dimmed back into their signature brown color.
"We have to promise not to tell anyone." said Skyfire.
