Metal Fire

SaberStar Brightwing shouted at the top of his lungs. "Doctor! Doctor! DOCTOR!" A brown Earth Pony wearing a green tie appeared out of nowhere.

"I'm here, I'm here! You don't have to yell! Oh. It's you and your.....friend." he replied.

"Yes Doctor it's me. Last time we met, I wasn't the happiest. This time, I need your help. My friends have been kidnapped by the Changelings. I need your help getting them back." Saber explained.

"Did you say Changelings? Then we need to hurry. Get into the Tardis." the Doctor replied seriously.

"Tardis?" Rainbow Dash questioned,

"My ship." the Doctor explained. "We need to hurry." a police box, like the one Saber had seen last night, was in the clearing.

"Are those doors secure?" Rainbow said, looking doubtfully at the Tardis doors.

"Whole armies can't get through and believe me, they've tried." the brown pony said, opening the door. "Derpy? We have visitor!" The gray mare he'd seen last night came out. "Oh it's you and your......friend." she addressed Saber.

"Can we stop the whole 'you and your friend' thing?" Saber asked. "We don't have time!"

"Oh okay." the mare said, trying not to grin. Saber noticed that her eyes were crossed, but didn't comment. He also noticed her mane was tied in a ponytail by a key on a chain. Saber had a feeling that he was going to need an explanation .

"After you." the Doctor said. Saber walked in and couldn't believe his eyes. The inside was as big as his house. 'How' was all he could manage. "It's a time machine." the cross-eyed mare explained. "So, what are we doing Doctor?" she asked.

"Hold on." the Doctor said. He pulled out some sort of gadget. He scanned Saber and Rainbow.

"What the hell are you doing?" Saber demanded.

"Checking to see what species you are. Let's see, Pegasus and- hold on! You're not a normal Pegasus. Powers like fire conjuring, eye color changing, all sorts of things. Who are you?" the Doctor replied.

"Long story short, a Changeling cut them off and I got these powers. Now, we need to help my friends. Now." Saber said.

"Well then, avante!" the Doctor said he pulled levers and pushed buttons. The inside whirred. The room rumbled and then stopped. The Doctor opened the door and gasped.

"Doctor! What is it?" Saber demanded.

"The Changeling Empire," he said with awe, "Bit to dark for my liking." Derpy stepped out of the Tardis.

"Eww, this place is gross." she said. "It's like a giant beehive." Saber stepped out and agreed. The place was hideous. Green chrysalises hung from the ceiling, baby Changelings in them. Two Changelings were guarding them.

"I believe this is the hatchery," the Doctor whispered, "Where Changelings are born." and before Vinyl, Derpy, or the Doctor could stop him, Saber charged out and pinned both Changeling guards to the ground. His armor appeared on him like water was being poured over him.

"Where the hell are the four ponies you captured earlier?" he demanded.  The two bug like ponies didn't answer. "Answer me godamnit!" he flipped his wings to blade mode and pressed them into the Changeling's necks.

"The....Arena." one gurgled.

"Why are the in the Arena?" the Doctor asked

"We Changelings make our prisoners fight to the death, gives us more food than ever." The creature choked.

"Where is the Arena?" Saber demanded.

"Down the hall. First right" it gagged

"Thank you. And if you tell anyone about us, I will make you wish you could die." Saber threatened, releasing them. They ran of and stood against a wall.

"Rainbow, can you tie them up or something?" Saber asked.

"Of course!" She said proudly.

"Then make sure they can't get out. They want fighting, they'll get me." Saber growled.

When they got to the Arena, Saber fumed. Vinyl was facing Discord. He was towering over her and she was shaking in fear, cuts on her face and chest. Saber's eyes turned pure ice blue. His mane turned to ice blue fire and his wings were alight with the same stuff. He charged out of the hall he was hiding in.

"YOU BASTARD!" he yelled, "YOU HURT HER, I KILL YOU!" he leapt on Discord and decapitated the god of Chaos. He turned around turning normal. From Rainbow's point of view, he must've looked terrifying. Covered in Discord's blood, angry wings spread in blade mode. He saw Chrysalis shocked on her throne, but next to her was a higher throne. A male Changeling that looked like Chrysalis sat there with an enraged look on his face.

"Who are you to stop my entertainment!" the strange creature yelled. He flew down and hit the sand with a loud thump.

"I am SaberStar Brightwing! You, you beast have kidnapped my friends and you will pay." Saber said calmly considering what just happened.

"I do not think I will pay. Turn around and look." Saber did. Rainbow, the Doctor, and Derpy were all tied up in Changeling goo. "Give up or all you friends die." the creature said.

"And who are you to order that?" Saber defied.

"King Switch of the Changelings." he replied.

"I will only give in if you heal her." Saber shot back, pointing at Vinyl. Switch's horn glowed green and all the cuts disappeared. Saber ran over to Vinyl. He wrapped a wing around her and pulled her close. "Vinyl, it's me. SaberStar. I'm here." She looked up at him.

"S-saber? Is that y-you?" she asked, tired and losing conscious. She fainted in his arms. He picked her up and flew to his friends. They had scared looks on their faces. He followed the Changelings towards the cells.
