Chapter One

Small ant-like heartless appeared around him. They twitched and called out promises of power, fame, glory, but never came to close to him. Tempting him like a seductress tempts her willing victims.

Madara stared at them as more and more appeared around him. His own body felt weak. From his battle with Hashirama all those years ago to the recent use of Amaterasu on the Olympian; he just never had any time to fully recover. Adjusting his posture he stared back at the sea of yellow eyes surrounding him.

He moved his hand to his mask, noticing how they twitched and followed his hand. He removed his mask, leaving his bare face exposed to the crisp air. The only portion left unscathed was the right cheek and eye area of his face. His left eye was completely gone, leaving a gaping hole staring outwards.

Suddenly they all froze. He felt an impact on his back as three of them jumped at him; one to each of his knees and the other to his back. He twisted and landed on his back, dispelling his attackers in wisps of black and purple smoke. The rest of them stared at the smoke before jumping again with their twitching bodies and soulless eyes. They held down his weakened body with fingers like knives, writhing against his pitiful resistance. One clamored up on his chest and for a moment he felt real fear. Fear that hadn't been experienced since he first started going blind from his Mangekyo Sharingan.

Then it dove.

It clove through his skin like a knife through butter. Digging through muscle and nerves till all he saw was black.

When he awoke it was dusk; judging by the sickly yellow hue of the sky. He coughed hoarsely, spewing blood from his raw throat. The broken fountain that he saw upon his entrance to the Olympus Coliseum He crawled his way over to it and cupped some in his hands. Taking long drinks from the cool water he sputtered down the last he could.

'You are ours.'

He struggled to his feet and whirled around, searching for the source of the voice. He strained his ears but didn't hear anything else.

'Look in the water.'

He decided to listen and glanced at his reflection. He froze. Where once was horribly scarred tissue now sat the pristine skin that he had worn before his battle at the Valley of the End. His hair had lengthened to what it was before he adopted the persona of 'Tobi.' Expecting to see another Sharingan eye behind his hair he tugged it back roughly.

Then he discovered why the world was yellow.

Instead of his own eye, spinning lazily around his pupil, a sickly yellow eye stared back at him. It covered everything from his sclera to his pupil. Just yellow.

'You are ours…' The voice trailed off, but he still heard the mocking tone to it. He still saw the mirth in its-his yellow eye.

He staggered back and let out an agonizing scream.

Meanwhile on some far away island a door to darkness opened and admitted three young teens into its folds.

And opened in Disney Castle, vomiting them from itself as if they were rancid meat.

Green eyes opened in the dark room. Long green fingers probed around and turned on the lamp next to his nightmare-bed. Ruffled green hair stood on end as he glanced blearily around the plain room. The empty bed where his dog max slept before he died stood stark against the pale green wallpaper. Now it lay filled with dust in the corner.

He uncovered and stretched. His green limbs groaned in protest. Grumbling to himself he stood up and meandered over to his dresser. The image in the mirror showed bloodshot eyes and a drawn face. However it quickly morphed into the grim visage of his father. "Good morning father," he stated blandly.

"Good morning," It cried out in anger. "Nothing could be such a bother."

He sighed in exasperation.

It plowed on, "I'm sick of your sloth, you despicable retch." It snarled. "Go to your machine the fantastical-fetch." It bared its yellow uneven teeth. "Then I think its time to recite The Grinch's Oath."

He grunted and walked into the next room and into his machine. It tumbled and beeped cleaning his fur and teeth to make him respectably clean. He walked back in front of the mirror and stared back at the resonance of his father.

"Now repeat after me," It started, and he did so. "A Grinch is unhelpful, unfriendly, unkind, with ungracious thoughts, in an unhealthy mind." As he repeated the lines his mind cracked, and started to fall. "A Grinch is uncheerful, uncouth, and unclean." His fur re-tangled itself and his teeth yellowed. His once drawn face fell into a grimace. "Now say this together: I'M FRIGHTFULLY MEAN! My eyes are both shifty, my fingers are thrifty." His brow drew down and his face formed into a scowl as he parroted the lines. "My mouth will not smile, not half of an inch!" It formed into a thin line that raged the words from it.

"I'm a Grinch!" He cackled.

"I am a Grinch." He repeated again with increasing force.

"I'M A GRINCH!" (1)

In the brief time that the heartless possessed his left eye it had taught him much, just as he in turn had thrown some information at it. Like scraps to a ravenous dog he threw what he knew of his world and its inhabitants, politics and even the Bijuu.

It listened with rapt attention.

It had taught him how to summon more of its kin. But its most useful ability it bequeathed to him was the ability to open and walk the pathways of darkness.

But its attention always returned to the Bijuu. Like host like parasite he guessed.

It craved their power, having witnessed it through his memories. It gleefully told him of worlds where he could rebuild his 'Akatsuki' if only he would give it the Bijuu's hearts he could have their power. Then it spoke of the greatest heart. A giant moon-like object called kingdom hearts.

That was when it had his attention.

An: The Main Character appears next chapter. Woo! For Naruto. I'm kind of excited; it'll be the first time I write him. Also, I'm not sure where to go with the Grinch, just that I want him to be in it.
