Chapter 4-Team 8 vs. Sasuke, before Sasuke vs. Naruto
"Rasen Chidori no Tate," roared out a demonic figure, launching a dome of spiraling lightning, to protect itself from a large barrage of water needles, as the caster yelled, "Hijutsu: Sensatsu Suishō," in a Female, before a teenaged male holding a black sphere above the ground and then with the command, "Hijutsu: Mushidama," as he threw the black orb at the demon, while another female burst threw with the jutsu, "Suiton: Tsunami no Jutsu," while launching a tidal wave, they were team 8 with additional member Momochi Haku and the demonic is Uchiha Sasuke, and after Sasuke, along with Orochimaru, had ambushed both team 7 & team 8, while they were competing in the second round of the Chuunin exams.
Then after the main attack, Naruto of team 7 and Kiba of team 8 faced off against Orochimaru, while the remaining members of team 8, along with Haku charged off to deal with the Uchiha. So now we're back where we are, as Sasuke charged his chakra and ignited in a burst of black fire, before he roared, "Enton: Gōka Mekkyaku," unleashing a tsunami of jet black flames, that eradicates the area in a massive mess of destruction, but however Sasuke missed his target when they jumped to the skies and began floating on a cloud of Shino's insects, "Hinata-chan, we've got to put that fire out before it spreads to Konohagakure," Haku informs her sister/girlfriend, as Hinata nods and then remarks, "right," before she flip hand seals, commanded, "Suiton: Senjutsu; Tsunami," as Haku had flipped threw her own and reported, "Hyoton: Hyo-tora-sho no Jutsu," causing a large tiger made of ice, to run threw the area, sweating up a storm, while Hinata had conjured up a blanket of water infused mana, that dropped on top of the fire and cut off it's supply of fuel by rolling around, though while Haku and Hinata were attending to the flames, Shino was studying Sasuke in a logical fashion, searching for a weak spot, as Sasuke eyes began to shift and reform, before he intoned, "Susanoo."
As soon as the words left Sasukes mouth, his body became engulfed by an ethereal purple fire, forming a torso, arms and a demonic head, it looked like a glowing ninja demon, wielding a ghostly bow, on its back was a quiver of transparent purple arrows and strapped to the demons right arm was a turtle shaped shield. Then copying the movements of Sasuke, the Susanoo Warrior drew an arrow from its quiver and cocked it in the bow, before as he roared, "Drop Dead," Sasuke fired the arrow, at Hinata intent on killing her, but the ghostly arrow was blocked by a lavender colored energy shield as Hinata calls her attack, "Senpō: Senheki," and then Hinata counters with, "Senpō: Genki Dama," while she threw a small boulder sized ball of mana at Sasuke, but he glides into the air allowing the attack to pass under him.
Time skip an hour for a mostly stalemated battle
Now we find Haku and the 2 members of team 8, lying battered and broken at the feet of the demonic Uchiha Sasuke, as he surveyed his handiwork before heading off to find his true quarry, in the direction he seen them head, but he hadn't need to go as far as he thought, as he sees: Naruto and Kiba were now returning from their battle field and the later was looking a lot more worse off than Naruto, as Kiba was now fight the need to sleep, and had the look of concern.
With Naruto and Kiba, as they returned from the fight they fought with Orochimaru, though while the later had been showing signs of both inner and outer concern of his teammates, he was also pissed off, since Orochimaru hadn't been defeated/killed by Narutos finishing moves, rather the traitor had been a mud clone and when they found out, all they saw was a stone statue of him looking like he'd just came from a kiln. After then they searched to see if he was in the area, but came up with bubkiss and decided to head back.
When Naruto and Kiba returned the others, they found them: severely injured and Kiba throwing caution to the wind jumped into the field and ran towards his team, while Naruto spotted the last bit of Sasukes retreating form, before leaving Kiba to attend to his (this 'his' is Kiba) team and Haku, by giving chase after slamming his palm over his bloodlines filter reporting, "Saiya-Jin," causing his hair and eyes to darken, to brown and sapphire, and then brought up a aura of Senjutsu Chakra, before launching himself towards Sasuke.
After leaving Kiba to tend to the others, Naruto flew off to intercept Sasuke. Catching up to Sasuke, Naruto appears infront of him, arms thrusted forward yelling, "Katon: Senjutsu; Fainaru Furasshu," fire a wide spreaded beam of burning gold energy, that is when Naruto missed his target, as Sasuke barrel rolls to safety and snarls while going threw hand signs, before said, "Dobe, you'll for what you've done to me, Enton: Endan," where he finishes by breathing a giant black ball of compressed fire, with a triumphantly smirk, Sasuke watches as his jutsu encroaches the distance between him and Naruto, before it fell off his face as Naruto bats the ball towards the sky with a back handed slap (think of how the Z fighter deflect oncoming Ki balls) and then Naruto rears his fist back, launching forward saying, "You've done this to yourself Sasuke, by siding with that lazy sensei you had and making you blind to all but yourself, that in itself makes you unable to see when revenge is never the answer, but allow me to assist in correcting you, Senpō: Cho Ryu-Ken," while throwing a punch that turned him into a giant sized golden dragon, before he collided with Sasukes chest region, forcing him to be flung backwards and hit seven trees each one breaking under each impact, before Sasuke momentum died and he fell like a rock towards the earth, once he hits the floor Sasukes demonic form canceled out and he reverted human.
