Time for the boss fight.
Matt narrowly dodged his brother's swipe. "That was too close for comfort." he muttered.
"You won't harm my pack." Andrew snarled.
"Andrew, you and I both know you'll never have a pack. Such is the life of the KON."
"I won't let my past define me. This is who I am now." Andrew advanced on Matt, the younger dodging again. "Your fast." Andrew said, appearing next to him. "I'm faster. Wolf-Falcon Shotgun!" Andrew punched Matt and he hit the dirt. "I don't care what pacts you made to get here." Andrew hissed. "You will fail." the Wolf-Falcon made a dash for his brother.
...
Outside, the Rainbooms and Andrew's pack heard the explosion. "I have to get back in there." Twilight said, reaching for her bag.
"Are you crazy?" Sunset asked. "That thing deserves everything he gets. He probably helped the other one escape." Twilight did something that surprised everyone. She slapped the fire-haired girl, hard.
"No one talks about the King of the Night like that while I'm around." Twilight hissed. "He may have made some serious mistakes when he was in Equestria, but he turned himself around. He's my best friend and I couldn't ask for a better friend." Everyone stood, amazed at the usually quite girl's sudden outburst. Twilight returned to her pack and began rummaging around. "I put it in here somewhere." she muttered.
"I'll get Sombra." Lightning said. "We'll need him if we want to take that kid down." Twilight nodded and the athlete ran off.
...
"It seems you still let your rage control your actions." Matt said, reaching for his belt. "Let me help with that. Ice Of Uraza." he took a fan from it and pointed it to his brother, a huge icicle coming straight for him.
"The Hitaraki has nothing on me. Dragon fist!" Andrew's hand glowed red as he punched the ice, causing it to shatter. "Have to do better than that."
"How's this? Blades of Briggan." multiple energy blades came at the Wolf-Falcon.
"Better." Andrew replied as the blades he couldn't dodge cut him. "I'll finish what I started Matt, and I'll finish you off."
"No," Andrew heard from behind him, "We'll finish him off." the boy whipped around to see his pack, armored in silver plate and ready for battle.
"I told you to get well away from here." Andrew snapped.
"We heard the battle and thought you would appreciate the help." Twilight replied.
"That and if we let Twi come in here alone, you'd kill us." Lightning called. "Lightning Lance!" acting like she was throwing a javelin, a lightning bolt appeared and struck the now snarling boy.
"Crystal Cascade!" Sombra held out both his hands and thousands of crystals shot out.
"Techno Tornado!" Twilight spun and hit Matt with the resulting tornado
"Damn you all!" Matt shouted. "I'll be rid of you with my Nightmare of Nigasak!" Matt opened the Hitaraki and each of them fell.
...
Sombra couldn't see through the mist. "Show yourself!" he ordered. The mist cleared to reveal none other than "The Crystal Empire? How did I?"
"It's him!" somepony shrieked, "It's the evil king!"
"No! I've changed! I swear I've changed!" Sombra shouted, but the ponies kept running. "No, it wasn't my fault." the unicorn-turned-human said, "it wasn't my fault."
...
Lightning stepped out of the mist to see a track. "Alright, I'll run a few laps while I figure out a way to get back to the fight." She began walking, then looked down as she wasn't moving. "No." she gasped. Lightning was sitting in a wheelchair, and judging by the look of things, she had been there for a while. "No, no, no this can't be happening."
...
"What's going on?" Twilight demanded. The mist dissipated to reveal Andrew standing, his back to her. "Andrew, thank goodness." the girl sighed. As Andrew turned, his eyes were filled with nothing but hatred as he advanced on her. "What? No. Andrew, it's me. This isn't you." Andrew rose his blade.
"ANDREW!"
...
"Shadow Grip!" a black hand gripped Matt's. The boy was thrown back. Andrew charged at his brother and began slashing before he retreated.
"Reckless." Matt hissed. "Why protect your own pathetic sense of honor?"
"Your a fool if you think that's what I'm trying to protect." Andrew hissed in reply, careful to keep himself in front of his pack as he dashed.
"Fraid not. Crystals of Crysor!" Matt rose the Hitaraki and a crystal field encased Andrew.
"Release me." he demaned.
"In due time." Matt replied. "I was curious why the cute lavender one would fear you. It seems she's right to."
"Twilight doesn't fear me." Andrew argued.
"Oh really?" Matt asked mockingly. "Do you honestly think she understands our powers, and all their glory? You can see it just as well as I."
"Silence!" Andrew said, his anger swelling. Keep it together.
"You can deny my words all you want. It won't change any of your fates."
"Save your breath."
"Andrew, if you join me, we can return home and rule once again. What do you say?"
Andrew looked at his feet. "I am home. Wolf-Falcon Ground Shaker!" he said, stomping hard enough to break his brother's trap.
"So be it. Nightmare of Nigasak." Andrew collapsed. "Such a shame." Matt said. Then Andrew began doing something out of character for the situation.
He was laughing.
