The renegade Shinobi, a former member of the Anbu, was the genius of the Uchiha clan from the Hidden Leaf. In his youth, Itachi destroyed his entire clan, leaving only his younger sister alive. Itachi joined an international criminal organization, Akatsuki, whose activities sometimes led him to conflicts with Leaf's ninjas, including his younger sister, seeking revenge for her clan. He doesn't talk too much, is straightforward and he speaks without unnecessary words.
