Obito was a young Ninja of Konoha and left the at the age of nine, from there he went on to join a team lead by Minato. (Team Minato) The team consited of Kakashi, Rin and himself. The team worked with each other but Kakashi and Obito could never get on. Kakashi had always been a better ninja then Obito. Kakashi followed the rules to the letter and was considered a genius of Konoha. At the age of eleven Obito made the rank of Chunin. Obito always measured himself against Kakashi. But Kakashi had become a Chunin at the age of six and then at the age of thirteen he became a Jonin. It was here where we are first introduced to the team in one Kakashi flashback during the Naruto series.
Team Minato had been given a mission to destroy the to stop enemies from entering Konoha. This would aid greatly in the Third Great Shinobi War effort. This was the same day that Kakashi was given the rank of Jonin and each member of the team had all brought him a gift, first minato gave him a special Kunai and then Rin gave him a medical pack especially made for him. Kakashi placed his hand out to Obito who looked shocked and told Kakashi that he had got him nothing. Obito was jealous of Kakashi success in the ninja world and never really understood the young ninja. Kakashi replied that it was for the best as Obito would probably have got him something useless anyway.
As they left it was noted that Kakashi was now in charge of the mission and when they where faced with a group of ninja Kakashi lead the charge. Even after Minato had warned him not to, Obito agreed with the master but Kakashi ignored them both and took the charge, Kakashi was almost killed until Minato intervened and saved him as well as Obito who when attacked had froze up and began to cry. Kakashi said that this was not the way of the ninja and then the two began to argue, Obito said that something had got in his eye and that kakashi should have listened to Minato. Minato stepped in and told Obito it was impossible for him to have something in his eye when he has goggles on and that Kakashi had been reckless.
Not long after that Minato had to head to the front lines leaving the three young ninja to fend for themselves. As they camped Obito spoke to Minato and asked why Kakashi was the way he is. Minato went on to tell the story of Kakashi father Sakumo how his father had deiced to save his comrades and not complete his mission that lead to the death of many Konoha ninja’s. The village blamed him for those losses and he blamed himself, very few saw that he was in fact a hero for going back to save his friends, Later Sakumo took his own life and ever since then Kakashi has followed the rules to the letter. Obito now had a better understanding of Kakashi and the next day he began to follow Kakashi orders without question.
But disaster struck when Rin was taken by two Iwgakure Jonin. Obito wanted to rescue his teammate; But Kakashi said that the mission came first. Kakashi found himself in the same situation as his father had been in the past and did not want to make the mistakes that his father had. Obito disagreed and left Kakashi not before telling him that what his father did in the past made him a hero not a disgrace. Obito was confronted by Taiseki one of the Iwgakure ninja’s and was soon over powered, just then a flash of silver filled the air and using his father’s sword Kakashi entered the battle just in time to save Obito. As the battle raged on Taiseki managed to strike at Kakashi left eye, Kakashi had used his own body to block an attack meant for Obito. terror took over as he watched the blood escape his friends eye and wanting to fight back past the fear his Sharingan awakened , using it he killed Taiseki and helping Kakashi they headed for Rin.
It was here that Kakashi live would change forever, Obito and Kakashi fought against the last ninja and save Rin, As the battle progressed Obito and Kakashi worked as an unbeatable team and freed Rin, But the victory was short lived as the final Ninja caused a cave in, Obito dived in time to save Kakashi from a falling rock which landed on him instead. As Obito lay dying he gave Kakashi a final gift for becoming a Jonin his left eye ( Sharigan) Rin using her medical tech implanted the eye into Kakashi and using the Chordi broke free of the cave in and killed the Ninja who had caused Obito's death. Just then enemy reinforcements arrived and Kakashi fought to protect Rin, Telling her that he would not let her die as Obito loved her. Just as the battle was about to be won by the enemy Minato Namikaze and saved the two students and finished the mission with their help.
