Itachi is a member of the Uchiha Clan from the village of Konohagakure and the elder brother of Sasuke Uchiha. He grew up as the child prodigy of the Uchiha clan, establishing milestones for not only Sasuke, but also for future Uchiha to live up to. His early childhood was marred by war, the violence of which caused him to seek peace at any cost. Upon learning that his clan was planning a coup d’état to take control of Konoha, after his clan was accused of attacking the village with the Nine-Tails, Itachi provides Konoha with intelligence on his clan’s actions during his two years as a member of the ANBU. Over time, Itachi distances himself from his clan, as some clan members believed he murdered his best friend, Shisui Uchiha, to gain the Mangekyo Sharingan.
In reality, as Shisui possesses the ability to subliminally manipulate others and shares Itachi’s love for the village, he intended to use his gift on the Uchiha clan leader to stop the coup d’état. However, Shisui is mortally wounded by the Leaf High Council member Danzo Shimura, who then takes his eye to achieve his own ideal of peace. When Shisui entrusts Itachi with his remaining eye, Itachi covers up Shisui’s death to make it appear it was his doing. Eventually, in return for Danzo’s offer to spare his younger brother, Itachi slaughters his entire clan. After creating the misconception that he murdered their family in cold blood to give Sasuke the mindset to become strong enough to kill him once he is capable, Itachi leaves the village, although he warns Danzo not to harm Sasuke. Meeting up with Konoha’s Third Hokage Hiruzen Sarutobi, who promises to do what he can to look after Sasuke, Itachi reveals his intentions to continue to protect the village from the shadows. Soon after perceiving them as a threat to Konoha, Itachi joins the Akatsuki to ensure they do not endanger his village. Itachi becomes good friends with his partner Kisame Hoshigaki, who expresses concern for Itachi’s wellbeing.
Itachi debuts in Part I after Hiruzen’s death, when he uses his infiltration of Konoha to hunt down Naruto Uzumaki as an excuse to secretly check on Sasuke’s wellbeing. After engaging with Kakashi Hatake and some of Konoha’s forces, he reveals Akatsuki’s goal to gather the Jinchuriki which are the people that contained the tailed beasts which there are nine of. Itachi also learns that Naruto is under the protection of Jiraiya and sets up a trap to lure the experienced ninja away to grab the boy. However, as Jiraiya comes to Naruto’s aid, Itachi finds himself facing Sasuke and directs his brother back on the path of getting stronger by defeating him before he and Kisame fall back.
