Izuna Uchiha (うちはイズナ, Uchiha Izuna) was a shinobi of the Uchiha clan. He along with his brother Madara Uchiha are renowned as the clan's two strongest members.

Background

Eighty years prior to the start of the series, Izuna and his older brother Madara were said to be equals as the most gifted members of the Uchiha clan. They usually competed with each other every day in order to get stronger. Both awakened their Sharingan early in life, and they became the first Uchiha to awaken the Mangekyō Sharingan. Madara used the power of his Mangekyō Sharingan to take control of the clan, with Izuna at his side. When Madara eventually went blind, he took Izuna's eyes to regain his sight. Itachi Uchiha suggested that his eyes had been taken by force, however Tobi insisted that Izuna had willingly given up his eyes for the good of his brother and the whole clan, seeing that Madara needed to remain strong to protect the clan from its growing number of enemies. Izuna later died honourably in battle, fighting to the death even in his blind state.^[1]

Personality

Izuna Uchiha was a harmonic and devoted person. He also appeared to be very competitive with his brother, Madara, in terms of skill. Tobi also implies that Madara and Izuna were close as brothers.

Appearance

Izuna had long dark hair, tied in a ponytail that reached his lower back. He wore what most Uchiha wear, a blue shirt with the Uchiha Crest on his upper back and blue pants that are wrapped up in bandages at the ends. On his waist, he had a bandage belt that held a sack that presumably held ninja tools.

Abilities

As the younger brother of Madara Uchiha, who was the strongest of the clan, Izuna himself was said to have been equal to his brother in every way. Both of them had exceptionally strong chakra, even for Uchiha members.

Izuna mastered his Sharingan at a very young age, alongside Madara. Izuna's Mangekyō Sharingan, that developed some time after Madara's, took the appearance of three bars stretching out of his pupil. When Madara took his eyes, the two's Mangekyō combined. Izuna's loss of his eyes rendered him blind, but he managed to survive, and continued to battle. This sudden disability however eventually led to his death.

Trivia

• Izuna (飯綱) is the name of a fox spirit in Japan and of a mountain. The latter is usually called Mount Iizuna, though. Iizuna, written with the same kanji, is also the Japanese name for the least weasel.
• According to the Third databook:
  • Izuna's hobby was to train with Madara.
