Power Progression

Background and History

During the Third Shinobi World War, Fugaku took four-year-old Itachi to a battlefield. Itachi tried to help a wounded enemy, but killed the man in self-defense when he attacked. The experience led Itachi to question why people fought and what it meant to live 358.

The Inventory System ranked Itachi 16th among the shinobi world’s Kage-level combatants and identified him as a double agent. Its footage revealed a future in which tensions between Konoha and the Uchiha escalated after Shisui’s death 44 45.

In that future, Danzo presented Itachi with a choice: join the Uchiha rebellion and perish with his family, or help slaughter the clan and spare Sasuke. Itachi sought the masked Obito’s help and agreed to join Akatsuki afterward. He killed Uchiha civilians and his parents, then used Tsukuyomi to force Sasuke to relive the massacre and urged him to become strong enough to kill him 51 52.

Personality

Itachi is precocious and reflective, having questioned the meaning of life since childhood. He also defends his clan against outside contempt, challenging Tokuma Hyuga after Tokuma insulted the Uchiha 44 48 358.

The Inventory System describes his future self as rational and willing to sacrifice individuals for what he sees as the greater good, while identifying Sasuke as the person he loves most. After watching Sasuke’s story, young Itachi recognizes that his future self overlooked his brother’s feelings and wants to correct those mistakes 48 211.
