I've always loved both Bleach and Kingdom Hearts, but I could never decide which one I liked better. Then it hit me, they should have a massive fight! Come all Bleach and KH fans as I write a story of the ultimate battle between these two worlds. I will also throw in some other characters from Final Fantasy and possibly Soul Eater. (Note: if I get far enough, I will create two alternate scenarios for either side winning, but I will hold a vote to see which one I write first). (Another Note: This will be kinda Dissidia-like, but I hope you like it). (Last Note: The next three chapters will just be an intro to who the story is based around and the two OC's. If you want to avoid boredom, skip to chapter 4, coz that's when awesome stuff starts, but you won't really get what happens later on, so I suggest you don't. Just warning you so I don't scare you off by the boring parts.)

Disclaimer: I own neither Bleach nor Kingdom Hearts, or any of the other characters/references form other series.

It was a warm and sunny day, the cool Summer-like breeze whipping at Sora's spiky hair, wandering where he was or how he got here. The last thing he remember was being on the Destiny Islands, running along the sandy beach with Riku and Kairi, but now he was suddenly in this unfamiliar place. It seemed nice though. Lush green grass by the edge of a cliff which steeply descended into clear blue water. He looked up. The sky was a little cloudy, but apart from that, relatively clear. Sora felt that he had to go somewhere, so he picked a direction that felt right and started walking. He hoped that he wouldn't encounter any heartless. After a while of walking, he found what seemed to be a path. His surroundings half reminded him of the road to Castle Oblivion, which Riku told him about while they were still in the Realm of Darkness. He hopped onto it and began following it to wherever it may lead.

Ichigo felt half dizzy from what he just experienced. One moment he was just training with Renji and Rangiku in the Soul Society, or more along the lines of competing, before he found himself here on this path. He looked around, a cool breeze rustling in his orange hair. He seemed to be in a farm-like area, dirt with random tufts of grass. He chose one of the two directions the path could take him and started walking, not really caring where it took him, so long as he found something or someone at the end of the path. If he encountered any hollows, he might be in trouble without any help.

Riku had been walking for what felt like hours, trying to figure out what had happened. He was racing along the Island with his best friends Sora and Kairi, and then suddenly, there was nothing. He found himself in a cold, dark cave, the only light being the very dim glowing stone around him. This wasn't like it was his first time in the dark. Riku was used to it now, but he wasn't used to very suddenly finding himself in a dark place, even though that's sometimes how it seemed. He'd appeared with his back against a wall, and with only one way to walk. Just before he was about to decide to use his power to blast his way out, he turned a corner and found light pouring in from a hole high in the ceiling. He found a good climbing path and began his ascent to freedom.

Renji had his arms folded, walking through a lush jungle, busy with vines hanging down low and insects buzzing about. He was starting to get annoyed with this trick he thought Ichigo and Rangiku was playing on him. How or why did they dump me in this jungle? He thought to himself looking around. The trees were so high it looked as though they touched the sky, and the leaves didn't let through much sunlight. The path on the ground that he'd been following varied from being dry to sticky. Small flowers seemed to bloom everywhere, varying in colours and sizes. He unsheathed his Zanpakuto and began cutting through a group of thick vines and some twisting thorns that were blocking his path. Finally he came to a clearing. Another path, except this one went straight out into a plain. He hoped he could find Ichigo and Rangiku soon.

Kairi had found herself in a group of ruins of a castle after she seemingly just appeared there. She was a bit unsure of what to do. She didn't know whether to go into the castle or follow one of the many paths that stretched out to the horizon like fingers desperately struggling to reach out to something. She thought that maybe if she could get up high enough into the castle, she'd see the figures of her friends, even though it would be unlikely. She decided to go into the castle, running the risk of encountering heartless. The moment she opened the front doors, a familiar feeling flooded over her, as though she'd been here before.

Rukia looked around on top of the rotting wooden building, trying to reach out to see if she could sense other spiritual pressures. She could feel two which seemed to be getting closer, identifying them as Ichigo and Renji. But the other three… so bizarre. They were more like energies than pressures. She may have been able to sense them, but from these large ruins, she couldn't see much. It felt so familiar though, almost reminding her of the Rukon District. She started to walk calmly along the streets, trying to find her way out of the maze like area.

Sora had been walking for a long time, sunset approaching, his legs starting to hurt from the constant, repetitive motion. He had walked from the cliff, across a countryside, into a bushland, passed a mountain range and had come back to flat land. He felt as bored and tired as the Doorknob in Wonderland. He cast cure to feel more revitalised, spring returning to his step, but it still didn't change the fact he couldn't find Riku or Kairi. Then he saw a figure in the distance. It didn't look like anyone he knew, but it was worth a shot, better than being stuck alone. He ran as fast as he could, following the path, the Earth zooming beneath his feet. He was fast approaching the strange figure, which he could now see held a large sword on his back, the silhouette still undefinable in the setting sun. As he finally got close to him, he could see that the figure's sword was bandaged, like Cloud's and that the person was wearing a Black Kimono. From this angle he also looked like he had blonde hair. Who was this guy? The other man had obviously not noticed him, keeping his head straight and walking at his steady pace. Sora reached a crossroad in the pathway, which at this point the mysterious man finally saw him. He waited at the central point of the interlinking paths as the form zoomed towards him. Once the person finally reached him, he noticed that his hair wasn't blonde, but orange. He came to a halt in front of Sora, meeting him face to face.

Ichigo didn't know why, but he had a sudden dislike for this spiky haired clown. His large shoes, the way he stood, the jump suit he had on… it was unnerving. "Hello." The boy greeted. This was greatly annoying the Substitute Soul Reaper already, especially when the boys lips curved into a large, goofy smile.

"Hey." Ichigo replied, trying to hide his annoyance. "Who are you?"

"Oh," the teen replied stupidly. Did he think this was some kind of joke? At least Ichigo now knew that he wasn't the only one in this world. "Name's Sora." Ichigo nodded. Sora, a name he wouldn't be forgetting any time soon. The sun touched the horizon as a breeze blew across the open plains.

"Ichigo." He stated, only to get Sora to tilt his head to one side with a stupid look on his face. "My name." He growled through gritted teeth.

"Oh." Ichigo felt like facepalming himself. What was going through this kid's head? He was just going to plain tell him the truth about how he felt.

"I'm sorry, I don't mean to be rude," the carrot top lied. "but you're kind of annoying."

"So it wasn't just me now." Now Ichigo was confused. The crazy fool he was just talking to had suddenly turned into a serious young adult. "Looks like I'll drop my act."

"So you were playing dumb." Ichigo growled through his teeth, annoyance now flowing into his harsh voice.

"You couldn't tell?"

"To be honest," Ichigo put his hand up in the air and brought it back down on Zangetsu's hilt. "with an outfit like that, nobody could possibly take you seriously." The bandage around Zangetsu unwrapped, bringing his blade out, the sun gleaming brilliantly on the metal blade. He brought it up above his head, preparing to use his Getsuga Tenshou.

Sora watched as the white bandages gracefully unwrapped off Ichigo's massive sword. Sora took a few steps back cautiously, unsure what this guy was doing. The orange haired warrior brought the blade up above his head with ease, a blue aura quickly enveloping around him and the sword. Then suddenly, he swung the blade down with great force. As the blade hit the ground, the blue aura split the ground and flew rapidly towards him. Sora barely managed to dodge roll out of the way as the attack tore the ground where Sora was just standing. As Sora came up from his roll, he summoned his keyblade, getting a look of surprise from his new opponent. He took the opportunity to charge at Ichigo, thrusting the tip of the keyblade at his chest. Ichigo managed to jump out of the way at the last moment, narrowly missing a powerful blow. He seemingly hovered in mid-air before coming back down to the ground. They both stared at each other, getting into their battle stances. Sora kicked off the ground as he zoomed forward, holding the Kingdom Key by his side as he ran. Ichigo was approaching similarly, holding his Zanpakuto on his shoulder. The two swung with all their might, bright sparks flying their blades clashed. Ichigo used a flash step to appear behind Sora. The spiky haired teen was surprised by this, but deflected his opponent's oncoming strike. Sora shoved Ichigo backwards into the air, which in turn threw him back to the ground, and shot a fire spell at him. The carrot top flash stepped again, Sora watching carefully to notice how he does it. Ichigo tried to stab Sora with Zangetsu once his feet had found the ground after his flash step, but only found air when Sora copied the Flash Step. He appeared a few yards ahead and seemingly tripped, not quite copying the technique right. Ichigo shook his head and Flash Stepped to his new rival. Once he had appeared, Sora took a clumsy swing of his key to hit Ichigo, but only hit the metal of his blade. Sora jumped up and rolled out of the way of the retaliating blow. It was obvious that both warriors were equal in strength and beginning to get tired.

They jumped at each other, gripping their blades yet again, swinging as hard as they could at one another. They were just about to bring their blades to the full swoop of their attack when suddenly two pillars of energy crashed down upon them, Ichigo's blue, Sora's yellow. Once the godly columns had evaporated, the two fighters were nowhere to be seen.

In different parts of the strange world, each of the chosen warriors watched as pillars of godly light crashed down in the distance. After the strange energies disappeared, they turned their attentions to the setting sun, which after a seemingly long day finally sank into the horizon, bringing nightfall…

Well, that's it for now. Hope you liked it. Please R&R. This is just the beginning, later there will be some epic battles and romances between some characters, so I promise it'll get better. You can vote for which two characters on either side you want for the next chapter in your reviews. Thanks for reading.
