(This is my first Naruto fic, but I have been a fan for many years)
Sasuke and Itachi stare at each other with a hate deeper than Hell itself. Sasuke charges only for Itachi to jump out of the tent through the roof. Sasuke follows with kunai in hand and lands in the middle of the camp. Itachi and Sasuke charge each other and a loud clang rings through the summer night air. This gained the attention of the remaining army of sound and the Raikage's ninja. The ninja rush over to see their leader battle his younger brother. Sasuke activates his Sharingan and charges once more.
Itachi reads Sasuke's movements and evades Sasuke's attacks with ease. He senses a clone behind him and jumps out of the way of the attack. He lands in a tree. He decides that he won't resort to the Mangekyo just yet. He charges forward again and starts to throw flurries of punches, which Sasuke avoids. Sasuke throws a kick, which is also avoided. All of Itachi's men look on in amazement as the last of the Uchiha clan battle to the death. The attacks of the brothers have an almost graceful movement. Both Uchiha's avoid more attacks and jump away unscathed. Itachi decides that it's time to end the piece of crap known as his brother. He activates his Mangekyo.
(Outside of the Camp)
Naruto, Sakura, Gaara, Kakashi, Kiba, Usuigi, and Tsunade are watching the Uchiha's battle out. They need to destroy the rest of the army that is lead by Itachi. Kiba leads a small group of ninja around the army to flank them. Tsunade, Kakashi, Naruto, Sakura, Gaara, and Usuigi plan to lead the main assault on the camp. Sakura decides to start the battle herself.
Itachi hears a loud crash as Sakura punched the ground with her incredible strength. He sees his army get caught off guard and men are crushed from beneath by the crumbling ground. He looks to destroy Sasuke with the Mangekyo but sees that Sasuke is stopping him from going into his mind. The only way to fully stop the Mangekyo was to activate another Mangekyo.
"Alright, Sasuke. I'll have to kill you the old fashion way." They charge each other, unable to read the others movements. They both land a hard punch on the other's face and go flying back. Itachi starts to form seals along with Sasuke.
The men in the army are attacked from behind by Kiba. Many try to run away, but Usuigi raises a large rock wall to block their path of escape. Usuigi forms seals and clasps his hands together. All of the men in front of him see that their shadows fly to his clasped hands and fire back as shadow spikes, which impale them on impact. Gaara uses his Desert Coffin technique on several ninja at once. Heads explode as Sakura's punches collide into ninja's faces. Kakashi kills many ninja with his kunai and shuriken.
Itachi sees that he is losing and he rushes forward and before Sasuke can even react, Itachi knocks Sasuke unconscious. However, Itachi feels HIM behind him. He looks around his shoulder to see Usuigi. He looks to use his Mangekyo on him but all of a sudden, pain sears through his head. He sees that Usuigi's eyes are no longer human eyes. They are onyx black with no pupils. He charges forward and lashes at Usuigi with his kunai. The knife slashes through Usuigi's cloak, but misses Usuigi. Usuigi drops the cloak and pulls out a kunai of his own. They clash together multiple times and the kunai clang through the night over and over as they lash at the other only to be blocked by the other. The both throw their kunai at the other and form the shuriken multiplication technique. Hundreds of clangs ring through the air. Many ninja are caught in the middle of the barrage and blood sprays everywhere. They charge again with kunai in hand. Itachi jumps into a tree, throws thirteen shuriken. He makes them fire shuriken with his flame technique. Usuigi blocks all thirteen in a single swift movement. Itachi charges again but Usuigi jumps out of the way. All the other ninja had stopped killing each other and looked at this brute battle. Very little ninjutsu. Both Itachi and Usuigi charge again and they tackle each other. Itachi jumps away when they land on the ground. They both pull out their two final kunai and charge. Loud clangs ring again through the night. Both men throw their kunai outwards and clasp their hands together. The kunai circle the two men and all the other shuriken and kunai from the dead ninja, along with those of the living join the circle of flying weapons. Thousands of weapons are circling them. Suddenly the hundreds of the weapons attack each man. Usuigi and Itachi form shields of fire to block the attack from the other. The fire shields attach onto the weapons and attack the other man. Both men jump away and land in trees. Itachi forms some more seals and chunks of wood fly out of the trees and fly at Usuigi. Usuigi jumps out of the way just in time.
Sasuke regains consciousness soon enough to see this magnificent battle. He sees both Usuigi and Itachi forming complex seals. In both their hands appears a katana. They charge once more. Sasuke feels rain begin to pour over the battle field. Both Usuigi and Itachi jump onto a long branch as thunder roars through the night sky, and lightening sears through the black coat of night. Both men attack each other. The clangs of the crashing katana battle ring through the stormy air. Sasuke grabs the katana of a dead ninja and jumps behind Itachi. He slashes at Itachi but Itachi blocks both attacks with his katana.
Kakashi looks up to see Sasuke and Usuigi swinging at Itachi but to no avail. Itachi jumps over Usuigi and lands on the other side of Usuigi. Itachi thrusts his katana forward and impales Usuigi in the back. Usuigi falls out of the tree and collapses to the ground. Sasuke thrusts forward and he and Itachi begin a sword fight on the long branch, both fighting and balancing as well. Itachi jumps over Sasuke and tries to impale him as well. However, Sasuke blocks it and swings again. The battle rages on and suddenly lightening collides right between the Uchiha's. Both jump into trees and jump at each other again. Sasuke forms seals and uses his Phoenix Fire technique. Itachi dodges and counters with his own fire technique. Sasuke can't dodge it while in midair. Suddenly he feels something collide into him. He sees that it's Usuigi, who becomes engulfed in the flame. Usuigi once again crashes to the ground.
Naruto sees this and it fills him with anger. He forms about 20 clones that each pull out a kunai. They charge and Itachi blocks the attacks with his katana. Gaara fires sand shuriken at Itachi. Itachi jumps out of the way and blocks the sand shuriken. Sakura rushes over to the burning Usuigi. His skin is severely burned and his stab wound is gushing blood. She pulls him out of the battle and begins to heal him along with Tsunade. Itachi forms seals and creates hundreds of clones. They surround the ambush force. All of the ninja lead by the Hokage had killed the army of Itachi but now another army was made. An army of Itachi clones. The begin battle once again. Sakura managed to heal the stab wound. Usuigi stands up and rushes after the real Itachi in the tree. Usuigi jumps next to the demon. He forms seals for his greatest jutsu. Black flame fires out of Usuigi's mouth. Itachi easily evades. However, he sees the flame form into a clones. He tries to attack it with his katana. The metal evaporates into the air. Itachi jumps out of the way and uses the rain to form a water dragon missile. The dragon hits the clone but it evaporates on impact. Itachi realizes he can't destroy it. So he decides to kill what he can. Usuigi. He makes another dragon missile and fires it at Usuigi. However, Usuigi forms more seals and black fire surrounds him. The missile is unable to penetrate the shield. Itachi suddenly senses Sasuke behind him. He turns but suddenly his head feels like it had just exploded.
Kakashi and Naruto both see that Sasuke had made a fire clone of his own. It was regular fire but still a clone, and it punched the back of Itachi's head.
