THE VALLEY OF THE END - NARUTO VS SASUKE

"It's too late now…!" Sasuke shouted. He had Naruto by his collar with both his hands, before chucking him into the air ahead. "...Naruto!" The Uchiha then jumped ahead, before latching onto Naruto who was currently falling downwards with his body upside down. Positioning his opponent into a piledriver, Sasuke wrapped his arms around Naruto's stomach, while cross locking his legs around the Uzumaki's neck, and let gravity take care of the rest, driving Naruto's head far below them on the ground.

Naruto had yellow-blond, spiky hair and blue eyes. He had three whisker markings on his cheeks. He wore an orange and blue jacket with a white collar, a white swirl with a tassel on the left side, and a red Uzumaki crest on the back. He also wore orange pants with a shuriken holster on his right knee, blue sandals, and a blue forehead protector. However, right now he had Kyuubi eyes, red fox-like eyes.

Whereas Sasuke has black eyes, and spiky hair with a blue tint. His clothing consisted of a navy blue, short-sleeved shirt with a high collar, white shorts. He also wore a blue-clothed forehead protector. However, during this battle, Sasuke currently had his Sharingan activated, which consisted of three tomoes in it, and a red pupil.

The ground ended up breaking a bit, causing debris of rocks to scatter away from the point of contact. Naruto's head was driven straight onto the ground, right near the edge of a lake present in the battlefield. The sheer impact itself caused ripples of water to form from the edge of the lake, spreading far ahead into the water body.

Naruto's head twitched several times, before his body fell into the lake, his back floating on the surface. His body began to slowly drift away backwards. Sasuke got up to his feet, turned around, and took a few steps forward, before collapsing on his knees and hands. He began to cough roughly a bit, before gasping for air.

The two fierce ninjas were currently fighting in the Valley of the End; a place with two large statues across each other, a waterfall, and a lake. The two ninjas had been at it for a while now. Sasuke had decided to cut ties with the Leaf Village and go to Orochimaru in order to receive power and get stronger. Thanks to the Legendary Sannin, Sasuke had obtained the curse mark, which had increased his strength and power. Whereas Naruto was trying his level best to retrieve his best friend back. However, things were currently not looking good for the blond ninja, as his body continued to slowly drift away, before eventually coming to a stop. Upon his body floating in a singular place in the lake, a few more ripples spread around him.

INSIDE NARUTO'S SUBCONSCIOUS - KYUUBI'S CHAMBER

Naruto was now floating in a large basement. He was still floating on the water, but the water wasn't the same lake from before. The basement's floor was filled with water, causing Naruto to float on the surface even in his subconsciousness. His legs were sunk in the water a bit, and his hands were above his head with some distance in between them. His upper limbs were also a bit deep in the water. His eyes were slightly open, his pupils rolled back a bit near the back of his skull.. It looked like Naruto had passed out. To his right, was a ginormous jail cell that looked large enough to contain a monster the size of a tall building. Behind the jail, was the Nine Tailed Demon Fox, staring at Naruto with fury in his eyes. "You're weak, aren't you, kid?" the demon fox chuckled menacingly. "You better be grateful to me… and to the fourth Hokage who contained me within the likes of you!

BACK IN REALITY - VALLEY OF THE END - NARUTO VS SASUKE

Once Sasuke caught his breath, he stood up, and contemplated for a moment on his actions. He felt slightly bad for what he did to Naruto. However, in order to get power and revenge on his brother, Itachi Uchiha, he had to cut ties with the Leaf. The Uchiha turned around and saw Naruto's body floating on the lake. However, something was different this time. A red chakra bubble cloak began to form around Naruto's body, starting from his back, and spreading around before reaching the front of his body as well. Sasuke decided to walk towards Naruto to find out what the hell was going on. Using his Chakra, he was able to walk on the water surface easily. Once he got close to Naruto, his jaw fell down a bit. "What's going on?"

Once the shroud of red Chakra bubbles completely surrounded Naruto, with the exception of his head, the powerful Chakra, which seemingly had a mind of its own, lifted upwards, pulling Naruto along with it, and made the Uzumaki stand on the water. Sasuke widened his eyes in shock, as he watched Naruto's body getting lifted to an upright position. However, Naruto's neck was still bent backwards, like the red Chakra didn't bother to straighten his head.

Suddenly, Naruto's head snapped forward, and he delivered a ferocious and swift punch onto Sasuke's face, sending the Uchiha flying backwards into multiple summersaults, before falling near the edge of the river. Naruto's eyes were red and foxlike, his nails were sharp, his teeth had sharpened as well. Sasuke held his face and wriggled around on the edge of the river in agony, groaning in excruciating pain while lying down on the right side of his body.

Naruto groaned in pain as well, as the Demon Fox's chakra cloak surrounded his head, thus covering his entire body. The Uzumaki roared for a moment, before dropping on his hands and feet on the surface of the lake. Using his chakra, he was able to stand on the surface of the lake on all fours. His battle stance was now like a fox. Naruto's hands upon making contact on the surface, caused it to heavily steam up. There was also a chakra fox tail behind Naruto, along with two Chakra horns on top of his head that were pretty long. Naruto glared at Sasuke, who had managed to get up on his knees on the surface of the water. Using his Chakra, Sasuke was able to stand on the water surface using his knees.

The Uchiha stood up and rubbed his stinging nose to soothe out the pain, before finally letting his hands down. He had a good look at what Naruto had just become. Before he could react, Naruto crossed his arms together, before lashing them out sideways. The mere action of that caused a curved shaped shockwave that directed itself towards the Uchiha. As the shockwave zoomed towards Sasuke, water waves began to form below it. Sasuke crossed his arms to block the incoming shockwave. However, the waves below the shockwave grew in height, washing over the Uchiha and temporarily blinding him in the process. The young avenger could feel the effects of the shockwave. However, by the time he opened his eyes, Naruto had suddenly appeared in front of him with remarkable speed.

The Uzumaki slashed his hand towards Sasuke, wacking him away in the process and sending his body flying like a ragdoll. Sasuke was tumbling multiple times backwards in the air and water. However, he quickly tried to regain his momentum by shooting out his leg behind him on the water, causing water to erupt a bit from the point of contact, and thus slowing his fall. The young avenger's foot touched something wooden, and quickly stood upright on top of a wooden log facing vertically. As the wooden log bobbed up and down vertically into the raging wave of water current due to Naruto's shockwave from earlier, Sasuke stared at Naruto with caution and thought to himself, "What was that just now? Even if I'm able to read Naruto's moves completely, his chakra makes a separate move on its own. It seems like the Chakra is moving in accordance with its own will. Even with my 'eyes', I'm unable to read it completely. That red Chakra… that's not any ordinary chakra!" that's when Sasuke suddenly began to remember something Jiraiya, another legendary sannin, had said in the past.

FLASHBACK BEGINS

"Your target is Naruto, after all…" Jiraiya said with a serious look on his face, eyeing a certain man in front of him.

Itachi stared at Jiraiya with his sharingan. "To abduct Naruto is our number one priority placed by our organization, the Akatsuki."

FLASHBACK ENDS

"I see…" Sasuke gritted his teeth. "It appears that you have some sort of special power…"

"Now I understand!" Sasuke jumped from the top of the log he was standing on, and hopped from rock to rock. There were a few large rocks present in the river, and the Uchiha used his acrobatics to hop off the rocks easily. Meanwhile, Naruto charged towards Sasuke whilst running on all fours on the surface of the water with incredible speed.

Sasuke performed a couple of hand signs, whilst doing parkour on the rocks, before firing multiple medium sized fireballs towards Naruto. However, it was of no use, as Naruto managed to dodge every single attack, and he turned to his left before charging towards Sasuke.

Sasuke performed another series of hand signs. "Fire Style: Fireball Jutsu!" he puffed his chest and mouth, and bent his body backwards a bit. He then bent forwards and blew a giant fireball out of his mouth. The giant fireball headed straight towards Naruto, who was still running on all fours. It was not long before the fireball hit Naruto dead-on, causing a large cloud of steam to spread around rise up into the air from the point of contact.

Sasuke thought he had gotten his opponent. However, once the steam cleared off few seconds after the impact, he saw Naruto standing on two legs, completely unharmed. "That Chakra of his is protecting him?!"

Sasuke regained his composure and thought to himself. "Calm down… I won't be caught as long as I fight from a distance…"

Naruto slowly raised his left arm upwards, before lashing it forward. Suddenly, a giant red chakra hand protruded out from his left hand, extending and reaching towards Sasuke.

"W-What?!" Sasuke was shocked. He quickly jumped upwards, dodging the incoming attack. However, it did not end there, as the hand followed him even in mid-air! Sasuke moved and dodged Naruto's chakra hand in mid-air, before landing back on the water surface below him. Suddenly, circles of water waves formed around him with a distance of roughly ten feet away from the center, causing some sort of semi water tornado to surround the Uchiha. Naruto's chakra hand burst through the water walls surrounding Sasuke.

However, thanks to his advanced, three tomoe Sharingan, he was able to continue to dodge his attacks by sidestepping, dodging, jumping away, and so on. Since the top of the water tornado had an empty gap, Sasuke quickly jumped up into the air, escaping from the vertical vortex, before landing away from it on the water surface.

However, Naruto wasn't done yet. The Jinchuriki jumped backwards, and latched his Chakra tail onto a steep rock attached to a rocky wall behind him. He then used his tail to pull his body up towards the wall.

Naruto stood on the surface of the wall on all fours while still eyeing his opponent in the yonder, before using his tail to chuck himself towards the Uchiha. Once he was fast approaching his best friend while in mid-air, he shot his arm forward, creating a Chakra arm that protruded and shot forward around ten feet in front of Sasuke.

At first, Sasuke thought Naruto had missed, but then the Chakra hand had merely lunged underwater ten feet ahead of him. The hand directed itself below where Sasuke was standing on, before successfully grabbing and shooting him high into the air, smashing him into the opposite rocky hill behind him.

The sheer impact caused giant rocks and boulders to separate, break, and fall into the water, causing large splashes of water to erupt into the air.. The hand had driven Sasuke a bit through the rocky wall, damaging him in the process. The lake's water current continued to spread aggressively due to the intensity of the current battle.

Sasuke's body ended up falling into the lake from the broken rocky wall, before being washed away onto the other edge of the lake. His body was face first on the ground.

A huge earthquake-like pressure was felt behind Sasuke. The Uchiha slowly turned around and got up on his butt, and saw a dome of water rise high into the air, followed by an even more ginormous Chakra hand shooting out and towering Sasuke.

The Uchiha decided to turn around and run away, and the Chakra hand struck down. Fortunately for Sasuke, he managed to dodge the attack. Sasuke stopped running when he saw a rocky hill wall in front of him and turned around, leaning his back towards it. His hands were near his hip level, and were currently touching the wall. The Uchiha couldn't believe what he was witnessing, as he collapsed on his butt in shock. "Damn it…! This is ridiculous!" he began to activate his curse mark. A glowing orange mark began to spread across his face and body, the starting point being his left neck where the curse mark originated.. "All I can do is dodge…"

The cloud of dust that had formed from the ginormous hand's attack began to slowly dissipate, revealing Naruto standing on all fours with his Chakra cloak at the edge of the river.

Sasuke was about to get back on his feet, when the ground suddenly rumbled. The Nine Tailed Fox's chakra hand broke through the ground below the Uchiha and caught him in its grasp. Apparently Naruto had dug his Chakra hand underground, and ripped through till it was below Sasuke. Cracks began to form all the way from Naruto's position to Sasuke, and the chakra hand emerged in the air, tearing through the ground. Naruto yanked his hand backwards, reeling Sasuke towards him, before a ferocious right hook that sent the Uchiha flying and crashing back towards the rocky wall, breaking it even further and causing more debris of large rocks to fall down onto the ground. The Uchiha's body was tossed over like a ragdoll!

Once the cloud of dust that had formed earlier due to the impact, Sasuke was shown sitting on his butt with the side of his left elbow on a broken rock beside him. However, there was something different about him now. The curse mark from earlier had surrounded Sasuke, this time being black in color. The young avenger chuckled menacingly and slowly shifted forward on his knees and hands. "I guess it can't be helped…" he then looked up at Naruto with gritted teeth. "If I get tainted by this power, I wouldn't know what would happen to me in the end." he then stood up to his feet while saying, "But it can't be helped, can it, Naruto?" the curse mark began to glow orange once again. This time, it began to spread even further, turning his skin dark-gray, and his hair grew and turned dark blue. His eyes also turned dark grey with his sharingan still intact. "It is certainly true that you were special… However, I'm even more special than you." with his transformation complete, Sasuke chuckled sinisterly.

Naruto gritted his teeth, his eyes seething with rage. "By special… You meant that?!"

Sasuke cackled, raising his fists near his chest level and clenched them. He glanced at his clenched fists and smirked. "I don't feel like I'm going to lose."

Naruto charged towards Sasuke while scraping and breaking the ground with his claw, leaving trails of marks behind him. "Haaaa!"

Sasuke saw the attack incoming and simply smirked, as Naruto punched Sasuke, and both shot forward towards a nearby wall, breaking it in the process. The blond ninja then delivered a right hook, that sent Sasuke crashing towards the foot of the Madara statue which was present in the battlefield they were currently in.

However, as soon as the cloud of dust cleared, Naruto saw that his punch was blocked by…

A large… mutated… wing like hand?

Apparently, Sasuke grew webbed-claw-shaped wings from his back, which he could use to fly and glide.

The webbed claw shaped wing twitched a bit as Naruto widened his eyes and crossed his arms. The claw spread out and hit the Jinchūriki, sending him to the opposite side. He landed on the foot of Hashirama Senju and crashed, which ended up causing damage to the foot of the statue a bit.

Naruto staggered upwards and sat on his butt and saw what was ahead of him in shock.

Sasuke was squatting on the ground, with this claw-like wing moving to the side. The Uchiha groaned and twitched a bit before another claw-like hand protruded from his other shoulder, tearing and making holes in his upper clothing.

The newly emerged claw-like hand spread to the side. His new look almost looked like Jin Kazama Devil Mode…

Sasuke placed his hands on the ground while squatting whilst Naruto stared at his friend in shock. "Sasuke… you…"

The Uchiha opened his eyes, revealing the sharingan. The look Sasuke gave Naruto reminded the latter about Orochimaru.

Suddenly, Sasuke widened his eyes and groaned in pain. He gritted his teeth and remembered how one of the sound four members had informed him that overuse of the curse mark would eat his chakra away, and ultimately, he would lose himself forever…

"This body… It looks like there's no time to waste," Sasuke thought to himself while narrowing his eyes at Naruto.

The Jinchūriki got up to his feet and stared at his left arm. "I don't feel my left arm…"

"That power you have…" Sasuke began, as Naruto now turned his attention towards his rival.

Sasuke continued with a smirk, "…seems to involve some risks too, huh?" he closed his eyes for a moment before reopening them and looking at the statue behind Naruto. "Did you know… that this place… is called the Final Valley. I think this is the perfect battle stage, don't you think, Naruto?" and looked at his opponent once again.

Naruto remained silent while gritting his teeth, and the Uchiha smiled with confidence. "Ah yes, I did say there would be no more talking. Then how about we bring this battle to an end? All our battles up to now!"

Sasuke made a series of hand seals and placed his hand downwards while holding his wrist with his other hand. Gathering lighting in his hand, the high concentration of electricity produced a sound reminiscent of many birds chirping. The Chidori!

Meanwhile Naruto placed his right arm to the side, and began to create his Rasengan.

The Rasengan is a spinning ball of chakra formed and held in the palm of the user's hand.

Naruto, as a Jinchūriki, can use the Kyuubi's chakra to assist in using the Rasengan. He made a Rasengan without the aid of a shadow clone, using the cloak itself to contain it. Due to the Kyuubi's influence, this Rasengan was darker in colour and much stronger.

Sasuke placed his Chidori forward and then sideways, as the attack turned into a dark-ish color due to the influence of the curse mark.

While Naruto and Sasuke were about to charge towards each other, there was an ominous figure watching the whole fight from a distance in the air. Apparently, this person could float in air! This was none other than Fu.

Fu is a purple-skinned male with red eyes and white hair. He is fairly tall and well-muscled in build. He wore long sleeved shoes, mustard yellow pants, and a leathered, black shirt with an "X" between columns on both of its sleeves. He also wore glasses and had hair around the sides of his head buzzed short and the top of his hair as secure as a high ponytail.

"These two ninjas fight really well. Now… time to conduct a very interesting experiment!" Fu smirked as he folded his arms and continued to watch the fight from a distance in the air.

Naruto and Sasuke jumped from their respective places and charged towards each other.

"Rasengan!" Naruto shouted.

"Chidori!" Sasuke shouted.

Both ninja charge at each other with their ultimate techniques. They collide in an explosion of blue and red chakra that forms a swirling black sphere of energy. At the last moment, Sasuke chooses to punch Naruto in the chest rather than impale him with the Chidori. Likewise, Naruto only scratches Sasuke's forehead protector, disproving the Uchiha's earlier taunt about scratching his headband, minimizing the effects of the Rasengan.

The chakra sphere they had created from the clash caused some sort of white linings to spread across it. Naruto and Sasuke are left hovering within the sphere, gazing sadly at each other. A vision of a younger Sasuke and Naruto shows the two form a seal as a symbol of friendship, and they smile at each other. The bright light then slowly dissipates and as it fades away.

However…

"Alright! Let's see what happens if I do… this!" Fu laughed, as he materialized a sword in his hand, and sliced the air like a hot knife through butter, causing the sphere Naruto and Sasuke were in to suddenly disappear.

Fuu's sword disappeared, as the mysterious man adjusted his glasses and smirked. "It worked!"

MEANWHILE IN MOUNT PAOZU – GOKU'S HOUSE

Goku was currently sitting on a chair near the dining table. He had just finished eating his lunch as he patted his stomach and smiled. "Wow! That was amazing! Thanks Chi-Chi!"

Goku has black spiky hair, dark-coloured eyes, with 3 bangs hanging to the right of his forehead, and 2 bangs hanging to the left. His hair also stands up in the front with 4 spikes, and 3 bangs in the back.

He wore an orange Gi, and a black short-sleeved undershirt. He also wore dark blue boots with a yellow border and red laces and had the Kanji "turtle" on the back of his Gi, within a black circle with the inner part being white in color.

Gohan stared at his father after finishing his meal with good table manners and chuckled. "Daddy, you sure do eat a lot!"

Gohan takes after his father mostly in appearance, including Goku's facial features, black eyes and even his spiky hair. At the same time, he has his mother's light peach complexion rather. The young boy also had a… tail… which was long and prehensile with brown fur. For the most part, his hair was relatively well-kept. He wore a white sleeveless shirt and green pants with black boots with white lacing. This outfit was covered in a Hanfu-style top that was yellow with green sleeves and on the front his family name, 'Son'. Was written in a Kanji within a large white circle with black linings. He also wore a red cap with a… some sort of ball… attached to the top.

The ball looked like a crystalline sphere that featured four pointed stars in a rigid position, akin to glass art.

Chi-Chi just finished washing the dishes and turned around, smiling at her family. "Sweetheart, are you ready to leave for Master Roshi's house?"

Chi-Chi is a beautiful woman with long straight black hair, large black eyes, a lighter skin colour, and a curvaceous and slender figure. Her primary clothing was a purple dress that has an orange cloth tied on the top and a yellow sash. In the appearance, Chi-Chi's hair was tied in a bun but she still had her hair coming down on the sides.

Before Goku could answer however, he suddenly felt something outside. "H-Huh?" as he looked out the window that was near the main entrance from the chair he was sitting on.

OUTSIDE GOKU'S HOUSE

The large Chakra sphere materialized outside Goku's house and landed on the ground, causing an explosion.

KABOOM!

BACK WITH GOKU

"W-Woah!" Goku almost fell of his feet as the explosion caused a minor earthquake.

Fear began to crawl into Gohan as he ran over to his mom and held her. "M-Mommy? What's happening?"

Chi-Chi placed one knee on the ground and held her son tightly. "G-Gohan!"

Goku displayed a serious expression and decided to investigate what the hell was going on.

After exiting the house, he widened his eyes in shock and saw a cloud of dust, along with a crater in front of him.

BACK WITH NARUTO AND SASUKE

Naruto is shown lying on the ground, unconscious with Sasuke standing above him, revealing that Sasuke has emerged as the victor in their fight. Sunlight breaks through the clouds, illuminating the two boys, and focuses to a point on Naruto's face before it disappears altogether. Sasuke stares down at Naruto while Sasuke's own scratched forehead protector loosens and falls to the ground, presumably confirming that Sasuke has severed ties with Konoha. It begins to rain. Sasuke is wracked by a sharp pain in his arm and falls to his hands and knees.

Sasuke coughed out blood as it fell right above Naruto's head, and he found himself staring at Naruto's face.

After a moment of staring, he decided to get up and leave, when he suddenly noticed something very odd…

Sasuke got up and glanced around his surroundings in confusion. "Wait… where am I? I was in the valley of the end earlier… What is this place?"

"Uh, hey there! You okay bud?" a voice said from behind.

Sasuke spun around quickly and looked at the direction of the voice in surprise. "Who are you?"

Goku strode over to Sasuke with a confused look on his face. "I suddenly heard a loud explosion outside my house, so I came here to check what the heck had just happened…" Goku then introduced with a smile, "As for who I am, my name is Son Goku! What's your name?"

To be continued…
