Izuna Uchiha (うちはイズナ, Uchiha Izuna) was a shinobi of the Uchiha clan. He, along with his brother Madara, were renowned as the clan’s two strongest members in their lifetime.
Before the era of ninja villages, Izuna was one of the five sons born to Tajima Uchiha. However, three of his brothers died at the hands of the Senju, leaving the second eldest Izuna and his oldest brother Madara. Alongside Madara, Izuna was considered one of the most gifted members of the Uchiha. Izuna often competed with his brother as training.[3] As a child growing up during the war-torn era, Izuna once accompanied his father on a mission to kill Hashirama Senju, whom Madara — albeit unknowingly — had been meeting. Once there, Izuna and his father were confronted by Butsuma and Tobirama Senju, the latter of whom he acknowledged by name.
