Minato Namikaze -Yellow Flash-

Minato Namikaze, renowned as Konoha's Yellow Flash, was a legendary shinobi who became the Fourth Hokage of Konohagakure.

Sometime after the war, Minato, not yet thirty years of age, was chosen to become the Fourth Hokage. Although Minato was well liked by the villagers, some thought it was a mistake that Hiruzen chose Minato over Orochimaru to be the Fourth Hokage. At some point during his reign, Minato taught his signature technique to the Hokage Guard Platoon to better aid them in their duties of serving the Hokage at any given time. While Kushina was pregnant, he read Jiraiya's first book and liked the main character's determination — whom he believed to be just like Jiraiya — decided to name their son "Naruto" in the hopes that he would be just like the main character and, in turn, Jiraiya. Jiraiya warned them that it would make him Naruto's godfather, but they insisted that this was a good thing.

Because Kushina was the jinchūriki of the Nine-Tailed Demon Fox, special arrangements had to be made for Naruto's birth. Since the seal keeping the Nine-Tails within her would weaken during childbirth, Naruto would be secretly delivered in a remote location outside Konoha. ANBU would guard the area and Minato would maintain the seal while Kushina went into labour. Soon after Naruto was born they were found by a masked man who had killed the ANBU stationed outside and infiltrated the cave. The masked ninja killed Biwako Sarutobi and Taji then took Naruto hostage, threatening to do the same to him. Minato was able to take Naruto back, but this gave his opponent the chance to escape with Kushina to break the seal. By the time Minato found a safe place to put Naruto and then teleported to Kushina, he spirited her to safety just as the freed Nine-Tails was about to kill her. With Kushina looking after Naruto, Minato heads to Konoha to defend it from the Nine-Tails.

Minato arrived in the early stages of the Nine-Tails' attack. After protecting the village from the beast's Tailed Beast Ball by erecting a barrier and sending the attack elsewhere, Minato tried to reach the Third Hokage to inform him of what had happened, but was stopped by the masked man, who tried to warp him away. However, Minato flew to another of his kunai, and was quickly followed by his opponent. Analysing his opponent, Minato came to assume that the man standing before him was Madara Uchiha, which he discarded by saying that Madara was dead. When the two began fighting, Minato realised that the battle would be decided by speed, and by carefully timing his Flying Thunder God Technique, Minato was able to strike the masked man with a Rasengan and apply the Flying Thunder God Technique seal on his back as well. This allowed him to teleport directly to the masked ninja and uses a Contract Seal to sever the ninja's hold on the Nine-Tails before he could escape.
