Team Minato

Team Minato was a team that was headed by the future Fourth Hokage, Minato Namikaze with Kakashi Hatake, Obito Uchiha and Rin Nohara being the members of the team.

History
In the Kakashi Gaiden, which was set during the Third Shinobi World War, the team went to Kusagakure to destroy Kannabi Bridge to cut off supplies for Iwagakure ninja. Rin was captured by Iwagakure ninja during the mission. Kakashi and Obito rescued her but Obito was crushed by a cave-in caused by the Iwagakure ninja Kakkō. Obito gave Kakashi the Sharingan from his left eye and tells Rin and Kakashi to flee, before the second cave-in seemingly killed him with both Rin and Kakashi escaping to safety while being left grief-stricken by Obito's death.

However, in reality, Obito was saved by an elderly Madara Uchiha. Grateful to Madara for saving him, Obito began recuperating for an unknown period of time while also voicing his hope that he would be able to return home to his village and help his comrades despite Madara telling Obito that the injuries Obito had sustained in the cave-in would ultimately ensure that Obito would never become a fully-fledged shinobi ever again.

Some time later, under Madara's secret orders, Rin was captured and made the host of the Three-Tails with Kakashi eventually saving her. Knowing of her true purpose yet unable to kill herself, Rin, desperate to save Konoha from being destroyed at the hands of the Three-Tails opted to commit suicide which she achieved by impaling herself one of Kakashi's Lighting Cutter attacks which was originally intended to strike a ninja from the Blood of the Mist.

This ultimately cost Rin her life and she used her last ounce of strength to whisper Kakashi's name before dying seconds. This left Kakashi devastated and the Blood Mist ninjas annoyed that their scheme had failed while in the background, Obito who had witnessed Rin dying at Kakashi's hand was in a state of disbelief and horror. While Kakashi passed out a few seconds later due to exhaustion, Obito, unable to cope snapped and in a state where he was consumed by nothing but grief, anger and the strong, almost overwhelming need for revenge, responded by going on a rampage where he brutally and mercilessly slaughtered all the Blood Mist ninja on sight with the events later turning Obito into a disillusioned shell who soon became hellbent on creating a World of Dreams.

Some time later, Minato would sacrifice his own life to seal away the Nine-Tailed Demon Fox, who was released on Konoha by the masked man who was Obito in disguise. After Minato's death, Kakashi believed for a long time that he was the sole survivor of Team Minato.

However, during Fourth Shinobi World War, Kakashi was left stunned when he and everyone else discovered the mysterious "Tobi" was actually Obito in disguise. After being reincarnated by Orochimaru, Minato arrived at the battlefield and soon learnt the truth that his former student had been alive the whole time while realizing his student's role in the Nine-Tails' Attack on Konoha with Minato regretting what had happened, silently stating that if he'd realized that the masked man was Obito, then things would have been different.

When Obito, the Ten-Tails' jinchūriki was defeated, Minato managed to stops Kakashi, who only wanted to take the finishing blow, from killing his other student. The three then talked about the past, their regrets over Rin's death and how everything had turned out. Near the conclusion of the war, Obito sacrificed himself to save Naruto from a killing blow much to everyone's horror and shock. Using his Kamui and some of the Six Paths' power he stole from Madara, Obito's soul returned and temporarily merged itself into Kakashi, letting the jōnin use his powers his powers to help Team 7 defeat Kaguya Ōtsutsuki. Upon the war's conclusion, both Minato and Obito's souls moved on to the Pure World, leaving Kakashi as the team's sole survivor.

Trivia

 * The team makes a cameo before their actual introduction in chapter 122 and Naruto episode 72 during a flashback of the Third Hokage, and on the cover of chapter 16.
 * Kakashi noted many times that the current team he looks after shares similar dynamics to his childhood group due to the fact that Naruto and Obito both wished to become Hokage while both Kakashi and Naruto had a long-standing rivalry with Obito and Sasuke as well. The resemblance is furthered with a photograph of Team Minato being nearly identical to the photograph of Team 7.
 * Aside from Kakashi, all members of the team became a jinchūriki at one point or another.
 * Rin Nohara is the only team member not to have been brought back to life at some point to participate in the Fourth Shinobi World War.
