Hey! Alaska here. I have recently started watching Naruto and absolutely love it. I was rather disappointed the way Naruto reverted back to his normal self while fighting Haku and decided to alter that a little. ^^ You are in the presence of a major Ninetails fan here.

The wind rushed in a dangerous and deadly tornado of fire, the coloring of the hottest flames of fire, a deep orange and red. A youko head seem to shape itself from the fire swirling around a certain pinpoint where a small once human crouched over the body of his beloved friend and rival. It growled low in its throat before fading into the firey depths of the chakra swirling in a fiery haze around the fox boy.

Eyes as blue as the afternoon sky on a cloudless sunny day turned a deadly crimson, as red as when mortal blood coats the ground in a blood bath. Human like round pupils stretched themselves vertically to mear slits in the crazed red haze. Long canines grew to an inhuman size, poking out the corners of the number one loudmouth ninja's usually cheerful mouth, the lips now pulled back in a fearsome snarl.

Claws grew from the boy's fingernails, sharper than any blade in the entire universe and stronger than any substance on that planet. Human senses became sharper, as sharp as demon fox's and beyond. The face seemed to get sharper and more edged, the odd six lines, three on each cheek, stretched farther as the eyes grew a sinister and revengful look.

Those insane eyes searched before landing directly on a mask faced boy standing shocked in a mirror. Those lips pulled back even more in an evil smile that would cause any fighter on the earth to cower in fear or bolt. Those bulky muscles shifted to completely face the terrified reflection. Those human ears shrinking and returning to normal size, tips of fur poking out of the top of his head in rythm to the shrinking. Those eyes filled with the pain of loosing a treasured pack mate at the hands of an enemy. This enemy would pay severly.

The crazed fox-ninja lifted his head and let out an earth shattering howl.

Kakashi let out a muffled gasp, his eyes widening considerably and causing him to loose concentration. The seal......the seal put on Naruto to prevent exactly what was happening now.....It was going to break, he knew it. How could this happen? What the hell had caused Naruto to become so upset as to borrow the demon fox's chakra and possibly its body? No matter now, he needed to stop it before it got out of hand. Whipping out a seal, he began chanting in a low voice, hoping that this seal would be enough to stop Zabuza in order to completely seal the spirit fox.

Chanting faster, he felt the chakra in the direction of Haku rise considerably. The icy mirrors cracked one by one and snapping into a million pieces. Out of one of the mirrors materialized the stunned Haku. The icy fragments showered the ground around it, the pure heat of the fox's chakra causing the fog to completely evaporate into the air and allowing Kakashi full view of what was happening.

The chakra seemed to have settled the slightest bit, allowing full view of a very pissed off fox-ninja crouching protectively over what appeared to be.....Sasuke's body, and it wasn't moving. Naruto's eyes were wide and overflowing with pure fury, staring right into the shocked eyes of Haku, who was beyond thinking capability, otherwise he would have been hightailing it outta there.

An ear-shattering howl caught his ears and Kakashi began to panic, though it didn't show on his face. Once the seal broke, there was no telling what would happen if it did. There was always the slighest chance that through Naruto would be the fox, that he would recognize them and NOT go on a rampage. They would only now when it broke...... He knew the powerful seal would dissipate soon and there was nothing he could do to stop it......

Sakura shakily watched the events unfolding where the inferno swirled around the two boys, one snarling at what appeared to be the shaking body of the boy who started the whole mess. The irritating blonde ninja was just plain scary. Never had she seen him get this angry in the time she had known him. She began trembling at the shear velocity of his gaze when Naruto turned his full fledged scarlet eyes right onto Haku's only after flickering past hers.

Those eyes......they're nothing like Naruto's, They are so full of fury....there is nothing left of the kindness and cheerfullness that is always there. It is like he isn't even there anymore. What the hell is going on here?!

Suddenly Kakashi whirled to the clearing where flames now shot up and around where Naruto was, hotter than ever before.

The seal had broken.
~~~~~~~~~~~~~~~~~ Oh I am soo evil. OK guys! Tell me what you think!
