Rank: Yondaime Hokage
Personality: Jiraiya and Tsunade pointed out that, while Naruto physically bears great resemblance to Minato, his personality and style of Ninjutsu are almost identical to his mother. While Naruto is boisterous and relatively thick, Minato was calm, collected, and highly perceptive. When faced with an enemy, he could kill in cold blood, and seemed well aware of the terror his reputation inspired in his foes. He appeared to be respectful of those around him; he didn't like freely speaking about others' pasts, and was said to be a very nice person.
Jiraiya had said that Minato was a shrewd person, and was not the man who could do something without reason. He was also shown to be very analytical from how quickly he could determine the strength and weakness of Kakashi's new technique, the Chidori. All in all, Minato was known for his unbeatable determination and unbelievable drive, which he passed onto his son. His devotion to the village and his love for his friends inspired all those around him, and, as a result, he became well-liked by the villagers. Minato was nevertheless understanding, that Naruto might feel hurt by the fact that his own father had sealed a monster inside him.
Bio: According to those who knew him, Minato was a very talented ninja, having been considered a genius that appeared once a generation. He graduated from the Ninja Academy at the age of ten, and was added to a Genin team under the tutelage of Jiraiya. Jiraiya took a special interest in Minato, and accepted him as an apprentice, amongst other things teaching him the Summoning Technique.
In later years, Minato was put in charge of a Genin team of his own, consisting of Kakashi Hatake, Rin and Obito Uchiha.
Konoha's Yellow Flash
Minato with his students: Rin, Obito Uchiha, and Kakashi Hatake.
During Kakashi Gaiden, set during the Third Great Shinobi World War, Minato led his team on a mission into Kusagakure. Due to Kakashi recently being promoted to Jōnin, Minato gave leadership of the mission to Kakashi while he went to help Konoha's forces on the front lines. Before leaving, he gave Kakashi a special kunai as a congratulatory present, outfitted with the seal used for his Flying Thunder God Technique.
While helping his fellow Konoha ninja, he used the Flying Thunder God Technique to destroy all the opposing Iwagakure ninja in an instant. He returned to Kakashi in time to save him and Rin from another group of the foes, but could not save Obito after giving Kakashi his Sharingan. When Kakashi and Rin recovered from the ordeal, Minato helped them to complete the task of destroying the Kannabi Bridge.

Minato and Kushina.
After reading Jiraiya's book, where the main character was named Naruto, Minato said that the protagonist was just like Jiraiya. It was then that Minato revealed that he and Kushina wanted to raise their child to be a shinobi like the one in the book, and for that reason they decided to name him "Naruto" after the main character. Jiraiya pointed out that it would make him Naruto's godfather and asked if they were sure that they would want that. Minato stated Jiraiya was a good example for them all and that he could not think of a finer shinobi than him.
