The Ultimate Being

Sora held the Hidden Dragon, Riku with the Way to Dawn, Donald, Goofy, and King Mickey ready for battle. The Ultimate Being flew erratic patterns in the same spot, showing no real signs of hostility. "Let's see just how 'ultimate' this thing really is." Sora ran over, bringing the Keyblade above his head. The Being snapped physically, then swung in the blink of an eye. Sora flew back, landing where he stood before. The Being continued its dancing.

"It's fighting defensively." Riku lowered his weapon, the others following. Sora got up, brushing himself off. "It's going to wait for us to go to it."

"Then I'll just have to be a little faster." Sora charged again. "Drive!" Blue light flashed as Sora sped to the Ultimate Being with Wisdom's speed. He slid under it, shooting at the Being from beneath. It whipped around, using its long neck to lift Sora into the air, flinging him high above the building. Sora reached the peak of his lift, looking down. The Being flew up incredibly fast, charging him head-on. The Keyblade began to glow blue as Sora pulled it back. The weapon and the Being made contact, Ultima Masher driving through its body. The Ultimate Being absorbed the attack, then knocked Sora back down to the others. Sora got up, still hovering slightly. "I can't come up with anything stronger. Riku stepped in front of him, raising the Way to Dawn. A pool of darkness expanded around his feet, then began to envelope his body. Shoes turned to boots and jeans changed into a black jumpsuit. The black and red heart on his chest was framed with blue. It extended down his arms, ending in blue and black gloves. The cloth hanging from his belt waved in the wind as Riku completed his transformation to Dark Mode. He flashed over to the Being, swiping at various points on the beast in seconds. The Ultimate Being spun around, tossing Riku back over to Sora. They looked at each other, then charged together. Riku slashed up, flinging the Being upward. Sora followed it, knocking it back down. He beat it there, where he and Riku performed timed strikes on its body, and then knocked it into the air again. From there, they both jumped up with it. However, it caught on by now. A wave of electricity wrapped its body, then shot out in all directions. Sora was caught by a stray bolt, falling down to the building. Riku's body pulsed with darkness as he glowed a malevolent blue. He blinked away, then rushed the Being, flashed away again, and repeated. After a few strikes, he flew up above, then rocketed down. Riku grabbed one of the flippers, dragging it down with him. They hit the concrete, which smashed in, cracks shooting out in all directions. Spikes of dark energy shot up, adding to the effect and damage. He jumped back, taking in the view. The Ultimate Being dragged itself up, seeming to have barely been scathed. Everyone sagged, Sora and Riku groaning, raising their weapons again.

"Sora!" Goofy shouted. "You still have one option!" Sora looked at his pocket, then opened it. He pulled out the Keychain, which was laced with gold. The ivory heart-shape shone in the night sky.

"Ultima Weapon." Sora whispered. He removed the medallion Keychain from the Keyblade, revealing the black handle again. H clipped the Keychain on, holding it away from his body. A bright blue light shone as a blade materialized. The handle grew out in a extravagant pattern, the same pattern crawling up the glowing blue blade. Its gold lace shone as it finished the tip with a crowned heart. (Note: This is the KH 1 Ultima Weapon.) He instantly began to feel his vitality being drained away through the Keyblade. This was why he never used it; it required too much energy. He lifted the enormous blade, ready to fight again. He sped over, the Being meeting him halfway. He sliced straight through it, the two half falling to the roof, then melting away into mitochondrial slop. Sora reverted back to normal, falling to his knees. Ultima Weapon fell from his hands, clanking on the cold concrete. Suddenly, the mass lurched and jumped at Sora. It enveloped the Keyblade, Sora grabbing the head of the weapon. He pulled it out of the slop, the black handle flying out. It rolled over to Mickey's feet, its broken Keychain dangling off the end.

"Sora!" The King threw his inverted Keyblade to him. Sora grabbed it, slashing through the bulging mass in the center. The mass settled, then dissolved. Sora sat down, handing the Keyblade back to Mickey, who grabbed it by the blade, dismissing it with a flash of light. Riku turned around to see Vexen and Zexion standing on the opposite building.
"Humph." Vexen looked on the scene across from him. "I suppose it wasn't so ultimate after all." He turned around, and with a wave of his hand, opened a dark portal. Riku started running over, the King jumping on his back. They jumped over the gap, landing on the second tower.

"You're finished, Vexen." Zexion snapped his fingers, Riku falling to one knee. He struggled up, raising his Keyblade.

"Not today, boy." The stepped through the portal. "Not today." Riku, the King still on his back, ran through the portal just before it closed, disappearing. Sora, Donald, and Goofy were the only ones on the tower, the cold winter wind cutting through them like a knife.
