I do not own naruto anime, manga or other released formats.
Many ninja knew how that Konoha was built as a place to stop the fighting between 2 families. These families where the children and descendants of the children of the sage of the 6 paths. These families had a tremendous rivalry between then that lasted several generations. But this one village was formed to have a single place where the Uchiha and Senju could work, live and form ties with one another. The hope was with time they would grow closer and the fighting would come to an end.
There was a secret that everyone seems to have forgotten. These 2 families made a pact that said if one of the clan was ever hokage the other clan would be given the position as well to show that there was no ill will between them. The Senju and Uchiha clan heads knew of this pact and they each agreed to honor their ancestor's wishes.
When the first Hokage was named from the Senju Clan everyone in the Uchiha knew that the next Hokage would be one of their clan, so they trained to exhaustion. Training and becoming stronger than their predecessors because if a person was going to be Hokage the very best of the clan would be called to defend the village and the people. To defend the village a Hokage needed strength, wisdom, and a strong will.
But this pact was broken when the next Hokage was chosen and he was not an Uchiha. Two brothers felt that this would happen these were Madara and his brother. They knew that the Senju were not to be trusted. So in the middle of the night they left and said good bye to the Village hidden in the leaves forever for they knew that they could not stand to see this injustice happen and a tragedy would be born from this one act.
Madara and his brother went to live in an island surrounded by a strong sea currents. This was where they found the village hidden in the whirlpools. The two brothers were welcomed by the Uzukage and eventually each would do the one thing they never believed they would do. They each took an Uzumaki for their bride. Mito Uzumaki married Madara and they both lived pretty happy lives, his brother married Risha Uzumaki. both families eventually heard the news that made most couple very happy, they both were going to have children. Madara was happy to see the smiling face of his daughter Kushina but because she was a direct descendant of the Uzukage she was given the name Uzumaki, Madara understood. The only thing that mattered to him was that his beloved wife was happy, and his child safe. Madara's brother did not have such a happy outcome, during childbirth there was a complication and both Risha and her son died. It was only through Madara and his wife that kept his brother from ending his own life.
But these two brothers were not unnoticed by the Hokage and his subordinates. In time the 2nd world war came to start, but when this happened the Village hidden in the whirlpool was attacked. Kushina just a genin in service of the village was sent away to their supposed ally of Konoha. Madara knew that she was strong enough to make the journey alone, but he and his brother both stayed behind to protect their home. If Konoha had sent the aid that was requested, the back up in ninja squads that was asked for the Uzugakuru would have survived, but Konoha sent no aid.
Kushina was a genin, but she was also the one to carry one of Uzugakuru secrets. She was the second jinchuriki of the 9 tailed fox. This lack of support was for the sheer purpose to case that young woman to come to Konoha for refuge. But who would have known that there she would find love in a blonde ninja by the name of Minato Namikaze, and that their child would change the fate of an entire village if not the world.
(timeskip years later)
The fourth hokage had moved his wife and the wife of the third hokage to a secret place. Kushina knew that the kyuubi would take any chance to escape her prison. As Kushina began to go through the pains of childbirth the thing she feared happened. The kyuubi tried to break free, but what she did not count on was that Madara was there to see the birth of his only grandchild. As Naruto came into the world the kyuubi broke free and Madara made the only thing he could. Having learned all the sealing techniques of the Uzumaki he sealed they kyuubi into his newborn grandson, Naruto.
Danzo appeared from the shadows and killed Kushina. "This uzu bitch has served her purpose, we have no further need of her. The child will be our perfect weapon and with it I will conquer the world!" Madara hearing this was angry and all hell. Kushina had been bond to her mate by their very soul, when Kushina died, so did Minato. This man would use his grandson as a tool to do his bidding. "You bastard, you killed my child and her husband and you think I will let you use my grandson as a tool. You really think I would ever let you do that!" Madara took his grandson in his hands and with a sad look on his face gave him a kiss on his forehead. "Naruto nothing would make me happier than to see you grow with my Kushina and her husband. I will never let this man use you, but he is Hokage and here he controls everyone as puppets. Minato was the only one to escape with his mind intact. So I will send you to a different dimension, a new reality. To protect you, but know this grampa loves you very much. Be strong my little grandson and brake free our clan from the curse of hate. You are my last hope."
As Danzo tried to take baby Naruto his grandfather took both of his eyes and as a sacrifice he made a jutsu that no one would dare do. The trans dimensional jutsu would cost him his very life. But nothing would stop Madara from protecting his grandson and as the jutsu was made little naruto inherited his eyes. As little Naruto disappeared Danzo demanded to Madara to tell him where his weapon was. Madara coughed some blood, "Where you will never reach him, I die knowing that he will be safe. My precious grandchild will be free from you!" These were the final world of madara as he activated the seal on his body and a giant explosion happened. Danzo and his subordinates died burned to ashes. To the people that knew of the 4th Hokage's death all wondered, "What happened to the baby?"
Some times the world is full of tragedy, but sometimes Fate takes a chance to correct the cause of these tragedies. Sometimes Fate makes a gamble, but they always have a very large effect on the world.
