Disclaimer: I do not Own Naruto or Kingdom Hearts (including the multiple series it is comprised of.). They belong to their respective owners. Neither do I own the following series which may or may or may not be in this story; they also belong to their respective owners. And if at any time they want this story removed I will of course comply: Family Guy, Monk, Wall-E, Scrubs, Bloodrayne, House, Halo (Cameo), Pokémon (In cameo only), The Ruins, UP, Stargate, Magic: the Gathering (Brief Cameo), The Lord of The Rings, and Total Annihilation. I will add more to this list as the story progresses. These are just what I'm thinking of. Again I do not own any of the series featured here.

AN: This is an idea that has been running around in my head as I'm currently blocked on TTSAS:RoO; though I'm not giving it up I'm going to take a break from trying to force chapters out. This is a Naruto/Kingdom Hearts/Mass Crossover. I wanted to make a mass crossover that seemed believable; as far as fiction goes. And since most of the names aren't Japanese, I shall use the English standard of Given name followed by family name. Jutsu however, will be in Japanese. Magic will be in English. It'll be awkward I know.

Pairings: Unknown. Most likely will be a majority of het with some side Yuri and Yaoi.

Rating: M for future gore, horror elements, character death, implied…mature activities, and safety.

Warnings: Spoilers present. AU from the Kisame, Killer Bee fight onwards.


Prologue

The extraction process had begun.

In a small dark cave located in the far corner of Tsuchi no Kuni, the Gedo Mazo statue erupted from the ground; its hands splayed wide and eight of its nine eyes open. The final one in the center sat closed.

Eight figures hopped up upon the fingers; leaving the small finger of each hand empty. One finger dropped an orange clothed person in the center of the room. He signaled for the others to begin synchronization. They each preformed a series of hand signs causing the statue to start vibrating.

Its mouth opened emitting nine blue dragons that cast an eerie glow over the cavern. The eight figures stood with their hands in the ram seal as the dragons tore into the prone body, drawing amounts of sickly red chakra back into the statue.


Sasuke Uchiha grimaced as a scream tore its way from the body's throat. Next to him Karin and Juugo both looked ill. While next to Juugo, Suigetsu seemed to draw pleasure from each scream.

At the other hand the Sandaime Tsuchikage, Oonoki, wore a small smile as the son of his most hated nemesis met his just desserts. Standing next to him was the living Venus flytrap; Zetsu. Each half of his face twitched upwards in a smile as he thought of his impending meal.

Kisame Hoshigaki stood on the right index finger staring impassively down at the thrashing blonde. He shrugged his shoulder and continued to expel his chakra at an even level. Next to him stood the true leader of the Akatsuki.


Madara Uchiha stood in a perfect erect stance with the mask of his 'Tobi' persona covering his face. The Kyuubi Jinchuuriki had proven to be the most difficult to capture of all the eight hosts, excluding the Sanbi which had been a free roaming Bijuu. He shook his head out of his train of thought and resumed concentrating.

Two days left.

One day left.

….

Ignition.


He was moments away from becoming the Jyuubi Jinchuuriki, like the Rikudo Sennin had before him. But like his father, the blond annoyance proved to have one last trick up his sleeve. As he stared at the now violently glowing seal on his stomach he knew his Eye of the Moon plan was to fail.

In the last moments of the extracting the seal started to emit its own violent red glow. It spewed forth black smoke and black sparks. The flow of chakra to the statue slowed, the stopped, then reversed. The Statue groaned and let out a horrid screech as the Kyuubi's chakra was pull from its gullet and back into the seal.

The Screech caused Karin to lose her focus and release the seal. She fell to her knees on the finger tip and clutched her head in pain.

Suigetsu was the next to fall; his concentration was decimated; causing him to revert to a puddle of water.

Juugo succumbed to his madness soon after.

Sasuke and Oonoki dropped into to one knee at the same time.

Kisame had to release the seal to grasp the hilt of Samehada; who had darted towards the immense source of chakra.

Zetsu's two halves grimaced but continued to stand tall.


The Kyuubi's chakra that spill from the statue's mouth finally came to an end; but it hung in limbo; with eight stands of different colors attached to it. Then with audible snaps they broke.

The statue shuddered and vomited a rainbow. Eight different colors of chakra came from its now seizing stomach. The chakra spilled down the mouth and cascaded towards the body lying on the floor. They spiraled around his seal, hissing, roaring, crackling. Then with a rumbling flash the remnants of the world were scattered.


Across countless worlds innumerable yellow eyes stopped and stared upwards as a star blinked itself out of existence.


It bobbed along the blue waters; danced in the crystal clear waves towards the white sandy beaches of the island.

Dear Sora, Kairi, and Rikku,

I'm sorry to contact you so soon after your victory against Xemnas but it seems the worlds need you again. There's been a massive resurgence of heartless throughout the worlds; and quite a few worlds have succumbed to the darkness. I've tried to contact all the worlds where you have friends but I can't reach any of them. Meet me in Disney Castle in five days so we can figure this out.

Sincerely,

King Mickey.


He awoke to a spiraling green pool with wailing souls all around him.

He wondered where his plan went wrong. Kisame had successfully captured the Hachibi. Sasuke and Oonoki had wounded the Kyuubi Jinchuuriki enough for him to capture him. The extraction process had gone as planned…

Ah yes, There.

Something built into the boy's seal had prevented the Extraction of the Kyuubi, and ultimately the full awakening of the Jyuubi. Its body had been freed from the moon, but its mind and chakra had stayed locked away. The Gedo Mazo had been destroyed in the resulting explosion of Bijuu Chakra. Then all he remembered was darkness.

Suddenly his body stopped circling in the pool and was drawn upwards. He staggered for a moment while glancing around to give the illusion of disorientation. He stood in a large throne like room decorated with a large table covered in a map and figurines. On the throne sat a giant grey; human-like figure wearing a dark blue robes that trailed down to the floor into smoke. It looked down its long hooked nose at him as he stared at its gently wafting hair made of fire.

"Rise and Shine, Sleepy head." It cackled. "So cupcake; what's your name?"

He studied it for a moment longer. "Madara Uchiha." He responded plainly.

It rose up, standing at nearly ten feet tall. "You can call me Hades." He paused and grinned at him. "I've got a task for you." He continued while circling him, he snapped his fingers and a small doll shaped like Madara appeared in his hand.

Madara's eyes sharpened at the strange sight.

"You see there's this….Hero I'm having a problem with; and I want you to kill him." He grinned at him while flipping the statue in his fingers. "You see this figurine is the key to your freedom. Complete the task and ill set you free." He held out his hand.

Madara stared blankly at him through the eyehole of his mask. Gingerly he raised his hand and clasped the others.


He stared around him as he ascended the narrow stairwell up towards the Olympus Coliseum. He had tried to disobey the order at first but found himself compelled to follow it regardless of his own will.

He exited the top of the stairs into a bright sand filled area that held the gate to a giant limestone building. Stylized columns of limestone held the roof of the building up each depicting a different scene of the same hero defeating some monster or another: A giant Lion; a Multi-headed serpent, a three-headed dog, etc.

His Akatsuki cloak billowed around him as he approached the giant doors; all around were chunks of stone that had yet to be placed in their original positions. 'So a recent calamity…'

He reached to door and pushed it open steeping inside a small trophy room that had one corridor leading straight in the opposite direction that he came from. In one corner a short portly thing stood munching on a tin can. It had the lower body of a goat and the torso of a man, along with a pair of goat's horns adorning his head.

He cleared his throat startling the little thing and motioned towards the opening that was roped off.

The thing spit out the tin can and stared at him blankly. "So you want ta' challenge Herc?" it asked.

He nodded. It continued on. "There's one condition though. Since the recent destruction of the arena we have to charge all challengers so we can afford to repair. Is that…Acceptable?" He leered at the bulbous pouch upon his hip that Hades had given him. He nodded again.

The satyr got up off the block of stone and removed the rope leading him down the passage. He chatted about the history of the place but Madara found little interest in it. He was here to secure his freedom and nothing more.


The arena was a large square platform made up of stone squares with a plain pillar at each corner. In the center stood a large man with bulging muscles in a strange brown breastplate and armored skirt, held up by a brown belt with a golden medallion. The man's hair was a dark shade of orange, not unlike the jumpsuit of the Kyuubi Jinchuuriki. He stopped lifting the dumbbells in his hands and turned to Phil. "A Challenger?" his voice held an anthill of hope.

Phil nodded and gestured towards Madara with one stubby arm. "This here's...uh…" He stopped glancing back at him in askance.

"Tobi," he replied to the unspoken question effortlessly. He tilted his masked face. "Tobi is a good boy."


They stood across from each other The Son of Zeus and the Darkest Fan.

The duel was Set, The prize clear.

Should Madara win, His freedom was near.


The Olympian stood in a basic brawling stance while Tobi rocked on the heels of his feet. He cocked his head and activated his Sharingan behind the swirling mask. The three tomoe spun lazily around the pupil of his eye.

Hercules charged forwards with one fist cocked back, his intent clear. He swung his trunk of an arm down at Tobi but it phased straight through him. The momentum of his missed hit carried him down through Tobi and into the ground. He rolled with it and ended up crouched down ten feet away.

Tobi turned lazily. "Ne, ne, is that all you got Hercu-chan?" he asked with his higher pitched, child-like voice. "Ne, is it Tobi's turn now?"

Without waiting for an answer he dashed forward, his arms trailing behind him. He jumped aiming a spinning kick at Hercules's head, but it was blocked by his forearm. Tobi twisted his body around and jumped over Hercules; avoiding a swipe from the other man.

Landing in a crouched position he swung his leg around, intending to knock the other man off of his feet. It connected but only shook him. He shook his head and cart wheeled away from another stone breaking punch. He looked back up to find the Olympian's studying him, his eye drawn along his mask, straight into its eyehole. 'Perfect…'

He focused his Sharingan upon the other mans eyes. "Magen: Kasegui no jutsu," he whispered; the voice echoing through his mask.

Hercules froze his eyes clouded over as the sky bled red. Large iron stakes imbedded themselves through his flesh, digging through muscle before finding a foothold in his bones. Blood poured profusely from the wounds inflicted. He stared up with pain lidded eyes at the masked man. "W-what sorcery is this?" his voice trailed off.

Tobi stared at him; cocking his head to his side. "Sorcery? No; this is an illusion. And with no way of breaking out of it you're finished." He pulled out a kunai and moved to cut the other man's throat. The metal bent and buckled before shattering into tiny pieces. His eyebrows rose in surprise. "Hmm I suppose ill have to make things a bit messier then."


On the sidelines Phil, Meg, and Pegasus stared in horror as Hercules stopped and dropped to his knees. The two men had a short conversation, ending with Tobi trying to cut Hercules's throat. When that ended in failure he moved his hand upwards to his mask and tilted it to the side; revealing one blood red eye.


Madara blinked as his Sharingan morphed into its Mangekyo form. It truly was terrible that they all had to die.

"Amaterasu," he spoke as the world dissolved into black flames. He found it curious however that from Hercules's corpse rose a large pink heart that disappearing into thin air.


Meanwhile in the Underworld the doll of Madara dissolved.
