The rest of Kimimaro's fight with Itachi and Gaara will go unseen, because I want to focus on Naruto's battle with Sasuke, but don't worry - they'll come back soon.

Nutjob117: Will try my best ;)

Corpj123: I'm not afraid to admit it - I actually AM a lazy writer.

WaterDrop: Sasuke, a good guy? We will see.

Thanks to Nutjob117, hi1235, Corpj123, S.R.457, WaterDrop, slashrunner and FireIce for the reviews!

The Totsuka Blade slammed into Kimimaro's body, but it was soon revealed to be a clone.

His proficiency with clones... it's annoying, Itachi thought. I'm starting to run out of chakra... I have to get him with my next attack...

Gaara lifted himself and his sand platform higher into the air warily.

The two awaited their opponent.

Kabuto looked behind him, to see Orochimaru resting on a bed. "The Four said they were going to seal Sasuke Uchiha up in the coffin right after they captured him... so the Cursed Seal process should be finished by now."

Orochimaru nodded. "And?"

Kabuto frowned. "Will Sasuke come willingly?"

"Ah..." Orochimaru smirked. "That is something I have thought of."

Puzzled, Kabuto gave his master a questioning look, who returned it with an evil glare.

"The stage two of the Cursed Seal can completely corrupt your mind."

Pushing his glasses up, Kabuto stared at Orochimaru. "Really?"

"That is, if you are a... 'good guy', as they describe it." Orochimaru's evil smirk continued to play on his lips. "The Seal's power is only great enough for a person who wants that power."

Kabuto's glasses dropped, but he pushed them up again. Orochimaru stared at them, convinced he needed to get a new one that wasn't as loose.

"Sasuke-kun doesn't want that power. He is a 'good guy', that 'I'll fight to the death to protect my village kind,'" Orochimaru mock-yawned and snorted at the same time. Then his face grew into an evil one again.

"The Cursed Seal level two form will corrupt his mind, as I have said. He will become a power-hungry individual, someone who wants to keep the power that is currently running through their veins for good, and get even more. That is why he will come to me."

"Narutoooo!"

"Sasukeeee!"

Sasuke threw a punch first, but Naruto twisted his body in mid-air to avoid it. However, one of Sasuke's new hand-wings clenched into a fist and shot forward, hitting Naruto.

Those wings act as fists too?

Naruto landed on the statue of Hashirama, and Sasuke followed soon after.

"Sharingan!" The Uchiha activated his dojutsu.

"Come on, Sasuke," Naruto pleaded. "Come back. Be the Sasuke me and Sakura-chan knows!"

Snorting, Sasuke simply did hand seals. "Fire Style: Phoenix Flower Jutsu!"

Naruto gasped as the 'small' fireballs came out of Sasuke's mouth. They were now bigger than the standard fireball of a Fireball Jutsu.

"You can't dodge this!" Sasuke threw his head back in a creepy laugh. "Die!"

Naruto glared at the fireballs and focused. If this doesn't work... I'll die!

Thankfully, it did.

Sasuke screamed in pain as he was engulfed by fire.

Naruto smiled, now standing at Sasuke's spot. "Substitution Jutsu."

"That... that was a lucky shot... you dead last bastard..." Sasuke cursed, emerging from the smoke with new burns. He crackled with purple chakra. "Let me show you my new powers!"

"You talk too much, Sasuke!" Naruto's sword glowed green and he started waving it around. "Wind Style: Razor Wind!"

All of a sudden, Naruto found himself having to turn around to defend himself from Sasuke's punch.

"H-How did you get there so fast?!"

Sasuke smirked, his wings quickly aiding him in knocking Naruto to the ground.

"This... is... power!" He roared. "Keep admiring them, you dead last, because you'll never get them!" He swooped towards his teammate.

"Dead last...?" Naruto got up on his feet. "I have a name! It's Naruto Uzumaki!"

"You're the dead last for all I care!" Sasuke appeared behind Naruto again, and the blonde managed to land a strike. However, Sasuke's wing shielded him, and also punched Naruto away again.

How... how can I defeat Sasuke? Naruto thought, as he panted. He had minimally took part in two battles during the mission, and as a result, his chakra wasn't at an all-time high.

"Fire Style: Fireball Jutsu!"

Naruto gasped. The fireball was three times it's normal size.

He jumped into the air, back onto Madara's statue, the fireball burning off Hashirama's hair.

"Fire Style: Fireball Jutsu!"

Naruto gulped as a new fireball was sent his way.

He contemplated using his Wind jutsu to counter it, but then remembered the battle with Kimimaro and how the Razor Wind had powered up Itachi's Fireball, and decided against it.

Instead, the young Chunin settled on diving to the side, and did so just in time.

I guess this will be the first time I can properly test that new jutsu!

Praying it would work this time around, Naruto bit into his thumb. Doing the required hand seals, he placed his palm on the ground. "Summoning... Jutsu!"

Sensing a new arrival to the battlefield, Sasuke looked up.

"Bring Down the House!"

Naruto smiled as a giant toad crashed into Sasuke, sending him sprawling onto the ground.

Unfortunately, Sasuke soon disappeared.

Naruto jumped forward as Sasuke appeared behind him, with a failed attempt to strike with a close-range Chidori.

"Hm?" The toad stared at Naruto. "A new summoner!"

"Oh, hey." Naruto stared at Sasuke as his Chidori crashed into one of the trees, bringing it down entirely. "I am Naruto Uzumaki! Well, as you can see, I'm in a bit of trouble here..."

"Right, I am Gamahiro, but we will do the proper introductions later." Gamahiro pulled out two swords from his back. "As you are my summoner, I will assist you in your fight - although you seem a little too young for my tastes."

Before Naruto could retort, Gamahiro charged forward. Sasuke pulled his arm back, and turned to see the toad.

Gamahiro brought his first sword down, but only succeeded in splitting the stump of the tree that Sasuke had destroyed into two. The winged boy had long gone, and was now charging towards Naruto with a newly-powered Chidori.

Naruto glared as Sasuke came charging towards him. Could he really bring himself to kill a friend?

As Sasuke neared, Naruto realized he could, and swiftly jumped out of the way. Sasuke's Chidori slammed into the back of Madara's head.

Gamahiro charged again, but Sasuke leaped away before he could be attacked.

He threw four shuriken at Naruto. "Fire Style: Phoenix Flower Shuriken Jutsu!"

Placing one of his katanas in front of Naruto protectively, Gamahiro knocked away the flaming shuriken.

"What a troublesome toad," Sasuke spat. "I'll take you out first." He jumped towards Gamahiro, aiming a punch for the aquamarine-colored amphibian.

Gamahiro responded with a swipe of his katana, but instantly Sasuke was behind the toad, swinging a Lightning chakra-infused kunai.

Naruto rushed to defend his summon, fighting off Sasuke with his sword.

"Thanks, kid!" Gamahiro turned around to face Sasuke. "You are not half bad, after all."

"Take this!" Sasuke screamed, throwing the chakra-infused kunai at Naruto, who beat it off with his sword again.

"Shadow Clone Jutsu." Two Narutos appeared beside him, and they rushed at Naruto. The original leaped into the air, and all three cornered the winged beast. "Leaf Style: Crescent Moon Dance!"

Sasuke glared at the three Narutos gaining on him. Nobody could see it - but one extra tomoe had appeared in his Sharingan.

He jumped into the air first, taking out the Naruto at the top with a kick. Swiftly, kunai were thrown at the other two Narutos' vital areas, dispersing them.

Gamahiro jumped in right after the dispersion of the clones, but was knocked away with a strong punch. The giant toad crashed into the Madara statue.

"Gamahiro!" Naruto yelled.

"You don't have time to be worrying about that toad!" Sasuke chuckled, whipping out a kunai and infusing it with Lightning chakra once more.

Glaring at the person he considered his best friend, Naruto prepared to continue the battle.

"I can read all your movements. It is obvious who is going to be superior in the result of this fight." Sasuke boasted.

"You talk too much..." Naruto replied. "... Sasuke!"

The smirk on Sasuke's lips grew wider, as he slammed his kunai into the chest of a Naruto clone attempting to sneak behind him.

"I told you I'm able to read all your movements."

"But it's no use if you can't counter them!" Voices yelled from above. Sasuke looked up to see ten Narutos descending towards him, with their swords pointed straight at his head.

"Or can I?" Sasuke did the hand seals so quickly Naruto couldn't even catch sight of them. "Fire Style: Fireball Jutsu!"

A fireball, two times the size of the previous one, was fired onto the clones and dispersed them all, save for one. This particular Shadow Clone was quickly dispersed as Sasuke overpowered it swiftly.

"This guy is strong," Gamahiro remarked.

"You okay?"

"Yes, I'll live," the amphibian shrugged. He pulled out his two katanas and leaped forward to attack Sasuke again.

Sasuke threw more shuriken at his toad opponent. "Fire Style: Phoenix Flower Shuriken Jutsu!"

With a few swishes of his katana, the shuriken were all knocked away. Gamahiro continued his charge on Sasuke.

To Naruto's shock, Sasuke demonstrated his new-found strength, slamming both his palms onto Gamahiro and proceeding to lift him up into the air. With a distorted voiced roar, Sasuke threw his victim onto Naruto, who jumped into the air just in time.

Now charging for Naruto himself, Sasuke crouched and his wings did the punching for him.

Naruto desperately fought off the wings, but sailed into the air from a hard punch as Sasuke arose and pummeled him in the face.

The spiky-haired shinobi flew past Madara's statue and started dropping down the waterfall, but speedily, Gamahiro jumped to save his summoner.

With one of his inconveniently short hands grabbing onto Madara's finger, and the other squeezing onto Naruto's hand.

His wings flapping to lift him up into the air, Sasuke swooped down to Naruto, with both hands clutching onto chakra-infused kunai.

Gamahiro had other ideas. He hurled Naruto back up onto the statue himself.

Glaring harshly at the toad, Sasuke decided to go for him instead, but Gamahiro disappeared in a puff of smoke.

"Bastards..."

Flying back up onto Madara and towards Naruto, Sasuke managed to kick him in the chin.

A few punches from his fists and wings followed, knocking the bloodied Naruto to the ground.

"Just give up," he laughed, cracking his knuckles. "Although I'll still kill you if you give up, but... it's pathetic to see a small fly like you being tossed around by an elite like me. It's dirtying my hands."

Naruto got back up on his feet, and looked up.

Even in his Cursed Seal form, Sasuke was startled. The intense glare in Naruto's eyes were intimidating, to say the least.

The Uchiha frowned deeply as Naruto's blue orbs turned into a fiery red, and the whiskers on his cheeks became more visible - Sasuke couldn't find a better word to describe the blonde's new feral appearance.

A red cloak of chakra appeared, entirely covering Naruto.

"What is that?" Sasuke questioned, glaring as what appeared to be a tail of chakra sprang out from the back of the cloak.

"Raaaarrr!" Naruto leaped towards Sasuke with a ferocious cry, abandoning his sword entirely.

Flying back, Sasuke watched in awe as Naruto punched the spot he'd been standing on, resulting in a mini explosion.

Naruto wasted no time, immediately jumping out of the smoke to grab onto Sasuke and slamming him down onto the ground.

His fingernails growing notably sharp, Naruto landed a long scratch on Sasuke's face, drawing blood.

A pained growl followed and Sasuke kicked Naruto off.

"Asshole!" He cursed.

Naruto did not reply, simply springing forward to attack Sasuke again.

Seeing Naruto's sword below him, Sasuke grabbed onto it, and defended himself. Channeling his own Lightning chakra up the blade, he swung it.

Now with two tails on his back, Naruto completely ignored the sword, slapping it out of Sasuke's grip and dealing the winged monster a number of fierce punches and a harsh scratch to the chest.

He finished with a kick to Sasuke's face, throwing him to the ground.

"Kaaah!"

Sasuke coughed violently, and blood stains spilled his bare chest.

Crawling up to his opponent, Naruto gave him a crazy smile, before gripping onto Sasuke's face and hauling him into the air.

Next, Sasuke was mercilessly slammed onto the ground continuously.

When Naruto decided it was enough, Sasuke was thrown over Madara, but with his wings, returned to the safety of Hashirama's head.

There, he collapsed, panting wildly.

Seeing Sasuke was not finished yet, Naruto smirked, and prepared to leap over from Madara to Hashirama.

His glare on Naruto never fading, the bruised Uchiha focused all his chakra into his right hand. Instead of blue Lightning energy, black chakra appeared in his palm.

Naruto made the jump, his right hand pulled back, ready to unleash a killing blow.

Now with a scary amount of black chakra crackling in his right hand, the sound of flapping wings filled the valley.

Two voices roared, filling the night air.

"Black Chidori!"

Orochimaru put on his shirt, and fastened the purple rope belt around his waist.

"With all due respect, Orochimaru-sama." Kabuto's voice held concern. "You have not recovered, I really don't think you should walk around."

"They are taking too long," Orochimaru hissed in reply. "I will go and see what is happening for myself."

"Then allow me to accompany you, Orochimaru-sama."

Orochimaru waved his hand dismissively. "There is no need."

With that, the snake master walked out of the Oto hideout.

I wanted to have Naruto vs Sasuke go like two or three chapters - but obviously things never work out for me and I really couldn't find a way to lengthen their fight. So this is it - the Black Chidori vs the Raseng- oh. I mean, the Black Chidori vs Naruto's awesome Fox powers. Who will emerge victorious?

P.S. The aftermath of this battle is pretty interesting. Stick around.
