A/N: I'm working hard on this chappie! It is the best and final battle of the whole fic.
Crystal's POV: I struck first. I yelled and flew at Blackheart as fast as I could. He made one huge slice with the Darkblade and I found myself tumbling backwards through the air. I was much too small to do anything! Wait, if I could will the Crystal Blades into Card crystals and vice-versa maybe I could… I willed the Crystal Blades to be bigger. They grew twice as long. They were still light but their size nearly made me drop. I flew at Blackheart again, skillfully avoiding the sword and taking a slice at his side. It didn't do anything. The impact almost made me drop my swords. It was like Blackheart's skin was as hard as steel!

He swiped at me with a huge clawed hand and I descended enough to just dodge it. I flew back and tried to think. I didn't have much time to think because Blackheart was walking towards me. He spun around and I got whipped by its monstrous tail. I crashed into the side of a hotel. I ran out of the room and flew down the stairs. It would give time to think unless it…

I heard an unbearable screeching sound. It was like ripping steel… which was exactly what happened. The floor above me caved in and I saw Blackheart holding the top half of the building through the rubble. I flew through and flew away as fast as I could. I heard the wind roar and I looked over my shoulder. Blackheart was flying after me!

"Crud!" I yelled. I banked to the right and stopped suddenly. Blackheart gigantic body rocketed past me. It would take it a while to slow down. Think fast! I had Kairi's heart around my neck. The heart of a Princess of Heart. I've seen that it can fuse to a Crystal Blade, but there were two swords and one heart. I slowly flew backwards and I held the Crystal Blades in one hand together and took off the heart pendant with the other.

"Kairi… thanks," I whispered. I placed the heart pendant on both the Crystal Blades at the same time. There was a huge flash of light and the Crystal Blades changed in my hands.

Finally the light faded and I saw my new weapon. It was more like a lance than anything else. On either end there was a shortened Crystal Blade and the handles were elongated and fused together so now it seemed like a crystal lance with a blade on both ends. Golden crystal material was wrapped around the shaft and the spaces between the ribbon-like material had a repeated pattern of white and purple.

"Awesome… The Crystal Lance…" I said to myself. I heard a roar. I looked up and saw Blackheart flying for me! I rolled in midair out of the way and scraped its shoulder with my Crystal Lance. I saw the blade break easily through skin and tear through flesh. Blackheart screeched and flew back. His shoulder was bleeding grey blood.

"It seems like I can finally hurt you!" I yelled triumphantly.

"DIE!" I heard its huge inhuman voice yell. Its Darkblade met with my Crystal Lance and sparks flew. I continued to fight and it was sort of weird because I was exchanging blows with something bigger than most buildings. Then I suddenly swooped under its arms and gave it a huge kick in the stomach.

"HI-YA!"

I didn't expect it to do anything but Blackheart grunted and stumbled backwards. I guess I'm a lot stronger as the Angel of the Crystals. I smiled and was about to slice him, but he blocked with the Darkblade. We continued exchange blows for a long time.

It started using his claws and tail as weapons too, which meant I had to fly around to dodge a lot more. I was getting really tired. Blackheart was so much bigger than me and it didn't move around nearly as much as I did. I flew at it as hard as I could, twirling my lance. Surprisingly, little shards of crystal formed around me and flew at Blackheart.

"What…?" I said. Blackheart couldn't stop them and the shards embedded them selves on all part of Blackheart. Blackheart screeched in pain as grey blood started to dripping from where the shards hit. "You are becoming a nuisance!" Blackheart growled. The Darkblade blazed with black fire and Blackheart red eyes glowed dark silver. Now there wasn't any color on its body, only blacks and grays…

The shards flew out of it and I flew quickly out of the way. Grey blood was dripping from his mouth and he let the drops of blood spill into the Darkblade's fire. The Darkblade's fire grew larger with each drop of blood. To my horror it even sliced its own arm open to get as much blood as possible on the sword… but why? What was the increasing conflagration on the sword going to do? I found myself unable to move but to just watch. When its arm refused to bleed anymore blood, he touched his huge gash with the blazing sword. The cut was healed and it raised its sword.

I found myself able to move again and I flew towards it, and I could feel the scorching heat even from here. I started backing up now. Blackheart swung the Darkblade down hard and all the fire flew at me.

"Whoa!"

I flew fast, the fire seemed inescapable. The black fire closed around me in a ring and I knew I would have nearly enough time to escape through the top.

"Wait! I have power of my own!" I said. I didn't really know how to use my powers so I tried what I did last time. I spun the lance around above me until it became a white-and-purple blur. Soon the edges of the lance were touching the flames and I heard the something, almost tingling, like wind chimes. I saw the black flames solidify until they were just made out of solid crystal. I flew out through the top and back into the battle.

"But how? I have seemed to underestimate you," Blackheart grumbled.

"I've overestimated you. I thought you'd be a lot stronger!" I teased.

Blackheart roared loudly and flew at me as hard as he could to me, his blade wildly slashing everywhere. Note to self: Never tease a huge black dragon-like death-bringer. That would be bad. I flew backwards and deflected his blows. Well, I really didn't listen to myself.

"Yeah, you wasted all of that blood for nothing! You never hit me, a small harmless fly! You get injured by something that would be the equivalent of a toothpick to you! Talk about weak and worthless!" I continued. I was really an idiot. I felt the wind knocked out of me and I nearly fell from the sky. The gigantic Darkblade had hit my crystalline Crystal Angel Knights chest armor. Now there was a gigantic dent in it, at least it was just that, this armor is strong! I caught my breath and flew fast. I had provoked it, and this is what I got.

But I noticed that Blackheart had completely gone berserk. It wasn't really paying attention to where it was hitting. It would spin around wildly and slice, swipe with claws, or whip with its tail trying to hit me when I was far away from it. It crashed into buildings, shattered the tube of crystal fire, and demolished half of Las Vegas in its blind rampage. Then I saw how it was blindly slashing everywhere. It really wasn't concerned with protecting itself. This thing is really easy to tick off. That was its weakness! It would be dangerous, but it would be worth a try.

I weaved through its maniacally waving legs and tail until I made it to the black heart. I was about to plunge my lance into it when its tail knocked into me. The three spike-like prongs grabbed me and threw me. I was tumbling through the air, unable to stop for miles. I hit the mountain before I was even able to slow myself down. Blackheart was a large black dot from here. I sighed and flew back. This would tire me out, but I had to defeat Blackheart.

"I can do this!" I said to myself. I flew fast; I was a white and purple bullet in the sky. I saw Blackheart and then… I crashed headfirst into the black heart on its chest. I found that it was profoundly softer than the rest of its skin and Blackheart yelled in pain when I crashed into it. It swiped at me with a huge clawed hand.

I flew away, now I knew for certain that that was its weak point. But before I could do anything it swatted me away. Then we fought some more. I was getting tired, and bored. I needed to beat this thing. I made a bold decision to go right for it. I weaved between its arms, past the Darkblde and then… Searing pain flooded from my back to the rest of my body. I looked behind and nearly fainted from what I saw. My bird wing was cut clean off! It hurt and I could feel the wetness of my blood seeping through my clothes. But I was so close, I needed to finish this.

I stabbed as hard as I could at the Darkblade. I heard a sickening crunch, and I saw that my lance sliced right through the hand. Blackheart screeched loudly and dropped the Darkblade, where it laid on the ground uselessly. I pulled out the lance and with the rest of my strength, I plunged the lance into the black heart. It sunk in like a knife through butter until the whole lance was inside Blackheart.

"No! I cannot be destroyed! This is only a dream!" Blackheart screeched.

The hole that the Crystal Lance made widened and out poured… not light or darkness… but twilight. It was the Card Crystals, together. Light and darkness, Alysia and Laska. The hole widened and widened, until all of Blackheart was engulfed, and then the hole collapsed and there was a huge light purple explosion. Blackheart was gone. I landed on the ground, but then my remaining wing disappeared and I was back in my regular clothes, except Kairi's heart was once again a pendant around my neck. The pendant glowed, and a semi-transparent image of Naminé stood in front of me.

"Well done, Crystal. The Card Crystals have served their purpose and all life is safe, thanks to you but…" Naminé turned around so I couldn't see her face.

"What? What's wrong?" I asked. She turned around, and I saw her looking down and I saw that she was very sad. She took in a deep breath as if she was going to say something that would be difficult for me, and I wasn't far off.
