Hearts of Corruption

I punched Jack in the face, knocking his whole body away into the water. "How'd you get this tremendous power?!" Jack asked. I didn't answer and shot an enormous energy blast towards him. Jack tried to block it but it was too much for him. "Gah..." Jack said, injured. "I can't...compete like this...." Jack said weakly. "It's over Jack. Admit defeat." I said standing in front of him. "Heh...You don't know about my other form....do you?" Jack asked, coughing out blood. "Other form?!" I exclaimed, surprised. "Heh... Be honored though! YOU'LL BE THE FIRST ONE TO WITNESS IT!" Jack yelled while transforming. "Geh.... This power..." I said covering myself from the powerful winds created from Jack's power. There was a bright light from where Jack was standing at until a figure appeared in the smoke. "Heh.... Prepare to die!" Jack said, coming out of the smoke. Jack had transformed into a demonic pony. His eyes were now red and his body was now a brown and black-ish color. His wings had changed into demonic wings that no pegasus would have. Jack ran towards me at a speed where nopony could even compete with! "Hello." Jack said, while being behind me at a split second. I turned my head around and tried to attack him but he dodged it and instantly teleported behind me again but this time hitting me in the water. "Gah!" I cried in pain, while sinking down. Jack dived in the water and started punching me over and over while in the water. I could feel my bones being crushed by his punches. Jack punched me one more time and hit me near the clouds. "I can't....Feel....Anything...." I weakly said while keeping myself in the air. Jack teleported behind me and started charging a blast. "See you later!" Jack said as he shot out his blast at me knocking me down on the ground.

"Shit! Like this we're both going to die!" DL shouted "I guess I have no choice but to use the technique.". "What technique?" I asked. "A technique that could possibly kill you but....It will defeat him. For sure!" DL answered. "Kill me? How?" I asked again. "Well.... You know the darkness?" DL replied. "Yeah?" I answered. "Well....It'll corrupt you if you use this technique." DL answered. "How?!" I asked surprised "You're the darkness aren't you?!". DL shook his head "I can't control the darkness. I can only give you the power of it." DL answered. I paused for a moment until I made my decision. "I'll do it." I said. "Really?" DL asked. "Yes..." I answered.
