Background & History

Izuna initially trains under Uchiha Nagahiko alongside Sosuke. Proud of Madara and resentful of Sosuke's praised talent, he challenges Sosuke to a sparring match; Sosuke defeats him by reading his movements with the Sharingan. Though humiliated, Izuna's rivalry pushes him to work harder. After Sosuke later suppresses his Great Fireball Technique, Izuna begins treating him with the respect he gives strong opponents. 3 4

Madara's return reveals the depth of Izuna's attachment to his elder brother. Izuna avoids vulgar language in Madara's presence, embraces him immediately upon his return, and joins Madara and Sosuke in collective training. At this stage, Madara's pure taijutsu exceeds the combined abilities of Izuna and Sosuke. 6

Izuna fights alongside Madara and Sosuke during the attack on the Uchiha Academy. Despite being injured, he remains concerned for Sosuke after the battle and visits him repeatedly during his recovery. During this period, Madara discloses that Izuna has awakened the Sharingan. 14 15

Years later, Izuna reunites with Madara and Sosuke as one of the “Uchiha Three Stars.” By age ten, he possesses the Three-Tomoe Sharingan, Jonin-level combat power, and exceptional Fire Style proficiency. 82

Personality

Izuna is intensely competitive, blunt, and easily provoked when others challenge Madara's standing or dismiss the Uchiha. His early jealousy of Sosuke's talent becomes a long-running friendly rivalry built on mutual trust. 3 4 109

His loyalty to Madara is absolute. He is protective of his brother's safety, distrustful of Hashirama's influence on him, and openly hostile toward the Senju Clan after the escalation of the Uchiha–Senju conflict. 6 137 141

Despite his aggression, Izuna is devoted to the people close to him. He accepts the danger of infiltrating the Ninja Sect because Konoha is threatened, believing that his status as a publicly dead man makes him uniquely suited to espionage. 189

Abilities & Skills

Sharingan and Mangekyo Sharingan

Izuna's ocular power develops from the Sharingan to the Three-Tomoe Sharingan and eventually the Mangekyo Sharingan.

• Reads and anticipates opponents' movements in combat. 153
• Uses Mangekyo Sharingan and Susanoo against Senju Tobirama. 155

• Shapes fire-natured chakra around his sword for close-range attacks. 81 109

After reactivating his Mangekyo, Izuna gains Bishamon, a dojutsu capable of seeing future events. 189

• Supports his already formidable battle awareness and ability to avoid ambushes. 153 189
• Does not guarantee safety against attacks that are either overwhelmingly powerful or faster than he can respond to. 153

Rinnegan Flame Transmutation

• Cannot affect living targets or material containing chakra. 239
• Its flames cannot be absorbed or controlled through the Rinnegan or Karma Seal. 239

• Can continuously heat an opponent's defenses until they become harmful to the defender. 297
• Moves a battle near the sun to maximize the output of his thermal abilities. 297

Taijutsu and Swordsmanship

Izuna is an agile swordsman whose close-combat skill remains dangerous even against stronger opponents.

• Sosuke acknowledges that he cannot defeat Izuna in pure hand-to-hand combat. 189
• Combines swordsmanship with Fire Release and Susanoo for offense at different ranges. 109 155

Equipment

• Longsword — his primary weapon in sparring and battlefield combat; often coated in Fire Release chakra. 81 109
• Human skin mask — provided by Sosuke through the Art of Erasing Faces, allowing Izuna to impersonate Uchiha Yamazaki. 189

Relationships

• Uchiha Madara — Izuna's elder brother and most important bond. Izuna trains with him, fights to defend his position and legacy, and trusts Madara to intervene when he is outmatched. 6 136 275
• Uchiha Sosuke — childhood rival turned trusted friend and sworn brother. Sosuke helps restore Izuna after his death, assists his Mangekyo reactivation, and supports his infiltration mission. 4 166 189
• Senju Tobirama — principal rival. Izuna defeats Tobirama during the Land of Whirlpools duel, but later holds a lasting grudge over the ambush that led to his death. 155 165 239
• Uchiha Chiri — Izuna's niece and Konoha ally. They fight alongside Uchiha Shū against Momoshiki and Kinshiki, and Izuna later reassures her of Konoha's strength. 246 244

Story Role / Major Arcs

Uchiha–Senju War

Following Tajima's death, Izuna and Madara awaken the Mangekyo Sharingan together. Izuna assumes greater responsibility for the clan's military fronts, confronts Senju Takema, and later defeats Tobirama in a formal duel through Mangekyo, Susanoo, and Kagutsuchi. 136 141 155

Izuna is later gravely wounded in an ambush involving Tobirama and Uchiha Tetsuya. He dies from his injuries, prompting Madara to consider eye transplantation and Sosuke to prepare the Living Corpse Reincarnation technique. 165 166

Resurrection and Infiltration

Sosuke restores Izuna through Living Corpse Reincarnation, spending heavily to secure his return. Izuna later reactivates the Mangekyo and chooses to operate under the identity of Uchiha Yamazaki, infiltrating Kumogakure to investigate the Ninja Sect. 167 168 189 190

Defense of Konoha

During the war against the Ninja Sect's allies, Izuna battles Tobirama's army and contributes to Konoha's resistance against multiple villages. 211

When Momoshiki and Kinshiki attack, Izuna rapidly deduces that Tobirama was killed to harvest chakra. He uses precognition to evade Kinshiki's attack, then uses his Rinnegan flames to move the conflict away from Konoha. 246

Later Battles

Momoshiki, after absorbing Kinshiki, defeats Izuna and Chiri before Madara intervenes. Izuna is later effortlessly defeated by Ōtsutsuki Yayoi, recognizing the enormous gap between himself and a peak enemy while still trusting Madara to protect him. 247 275

After becoming a Divine Fire-level expert, Izuna uses his heat-based power against high-level invaders while minimizing collateral damage to the Ninja World. He eventually leaves the world because remaining near its sun risked endangering Earth itself. 297 302
