Minato Namikaze (波風 ミナト, Namikaze Minato), also known as Konoha's Yellow Flash (木ノ葉の黄色い閃光, Konoha no Kiiroi Senkō), was the Fourth Hokage (四代目火影, Yondaime Hokage) and the father of Naruto Uzumaki. He was the student of Jiraiya and the teacher of Kakashi Hatake, Obito Uchiha, and Rin.
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.
In later years, Minato was put in charge of a Genin team of his own, consisting of Kakashi Hatake, Rin and Obito Uchiha.
During Kakashi Gaiden, set during the Third Great Shinobi War, Minato led his team on a mission into Kusagakure famously known as "Konoha's Yellow Flash." Because Kakashi had recently become a Jonin, 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 wipe out all of the opposing Iwagakure ninja in an instant. He returned to Kakashi in time to save him from another group of Iwagakure ninja, but could not save Obito. When Kakashi and Rin recovered from the ordeal, Minato helped them complete the task of destroying the Kannabi Bridge.
