As I turned around the heartless me grew to be ten times its height. I felt the rage build up and something snapped inside of me. It has been so long since I truly let my rage out. I summoned the blades and got straight to work. I found the area to have a lot of things I could use to attack the heartless. The first things I saw were three catapults, the next was a ballista, and lastly was something that looked like a giant slingshot. I decided to use the ballista. I remember this being in one of the games and got on it and started moving the rope back to the latch and I pulled the release lever. I was shot towards the heartless and Landed on the area I assumed to be Its arm. I decided to see if The blades would do damage to the heartless so I plunged the blades into the arm as I jumped off the arm and stabbed it with the blades and rode down to the hand.
As I hit the ground the Heartless turned to me and said. "Bow to the darkness in your heart." It then brought its fist up and slammed it down on me. I was able to think fast enough to bring out my Deathstalker and it turned into a Keyblade in time for the fist to hit it. After this it recoiled in pain as this happened I saw a yellow bar appear and saw It had a small bit missing from it and it said Jason's Heartless
I noticed I still had my left hand's Blade of Chaos out while I had my Deathstalker Key active in my right hand. I activated my right arms chain and attached it to my Key. I threw it at my Heartless. It had actually hurt with the chain attached and I Jumped and pulled the chain to launch myself at my Heartless. I decided to make a claim at this point and deal with what might be said to me later. "You know nothing Dark one Gods do not bow!" As I said this I felt like I was being watched and made an assumption that Discord and Starswirl were using this fight to study me.
I saw the health bar had moved to show he had lost a quarter of his health, I decided to shout. "Tiid Klo." I used the time slow to run back towards the catapults and the big slingshot. When time returned to normal speed I was lowering the bucket and hopping into it. I then used my Blade of Chaos to hit the lever to launch myself. When I got in the air My heartless had turned to face me. I had been holding my key out in front of me in a Superman like pose when I hit. I saw this launch attack had dropped its health down to half.
I knew the next thing it would do was try to counter attack so I blocked its attack and made a run for the middle catapult. It had realized this and grabbed a blob from itself and threw it and it destroyed two of the catapults, both ones I had not used. It was at this moment I realized I forgot what Discord had told me.
I felt my rage at its max but did not use it. I knew it would boost my strength but I needed to weaken it more so I kept guard until I could shout again. "Discord I ask of you a favor. I need you to imbue my Blades of Chaos with light." I said as I blocked another blow.
"I can not do that because that is not how a heartless is beat or even hurt." Discord said from the heavens. It was at this moment I had lost control of my rage, and went all out with my attacks. I did not realize it at the time but, slowly the health of my heartless was lowering. By the time the rage had ended It had a third of its health left.
I decided it was time to end this. "Tiid Klo." I said as I ran to the giant slingshot and let out a roar as I flew. The time slow had stopped when I was midway to My Heartless. I plunged my keyblade into it and threw the blade in my left hand at the head of my opponent, I then pulled myself up to it with the chain. I then swapped out the keyblade for the other Blade of Chaos, and with all my might drove them both into my Heartless's head and pulled the head open.
Inside of the head I found a version of it at its original size. It had jumped at me and I did the same, it tried to grab me but I felt my skin harden and saw it turned to my Diamondhead form. I never knew about this and saw that it had the effects of The Dragonhide spell but was more of a passive ability. I decided to use fire to burn it away slowly and finished it by stabbing it with my keyblade.
When I was done and it had died it's black heart flew into me. "Bravo Bravo You have surprised both of us." Discord said as he brought me back to the room inside of the Crystal Palace. "You want to know why the Blades of Chaos did not work. Your heart was not in the attacks at first but after you raged. Your heart was behind every stab, cut, and slice. No matter what you did he was in pain after." Discord added and stepped back for Star Swirl to examine me.
As he got close he first examined my Crystal like skin and said. "His skin has completely transformed and became Crystal. This is truly remarkable." He then said, "Now this is more like the crystallization process of when the heart pulses." He then went to examine the markings on my hands. "These marks are truly astounding that are beneath his skin yet I can still sense the magical residue. But you know I am going to have to report that one line to Celestia in my reports right?
I simply said. "I have been given godly powers. Do you not agree with that, from what you have seen?" I then added. "It is needed if the foe you summoned me to face is that strong don't you agree."
"While that is true, how am I supposed to know you won't just take his place?" Starswirl responded.
"You don't." I said with a slight grin on my face as I closed my eyes and looked down I then added. "But I assume you have a plan for that."
