Itachi

Age: 17[38]-18[10] in Part I Partner: Formerly Kisame Hoshigaki Seiyu: Hideo Ishikawa[39] Voice actor: Crispin Freeman[40], Skip Stellrecht (Naruto Episodes 29-30)[41]
Itachi Uchiha (うちは イタチ Uchiha Itachi?) is a missing-nin from Konohagakure and is partnered with Kisame Hoshigaki. During his time in Konoha, Itachi's prodigious talents and rapid development into a skilled ninja earned great attention from his family, the Uchiha clan.[42] He eventually began to train under Madara Uchiha in secret, murdering his best friend, Shisui Uchiha, to gain the Mangekyo Sharingan.[43] He soon joined forces with Madara in the massacre of the Uchiha clan, sparing his younger brother, Sasuke Uchiha. Knowing that the blindness brought on by possessing the Mangekyo Sharingan could only be cured by taking the eyes of one's sibling, Itachi spared Sasuke so he could someday take his brother's eyes.[44] Hoping that Sasuke might obtain his own Mangekyo Sharingan by then, Itachi encouraged his younger brother to live hating him and striving to avenge the clan. [45]

Despite his status as a wanted criminal and murderer, Itachi does not display any open enjoyment in violence or combat. Itachi instead prefers to avoid battle or, if that is not possible, end it quickly while exerting as little effort as he can.[46] When he does fight Itachi remains stationary, attacking only in defense and to otherwise avoid damage. He also studies an opponent's movements with his Sharingan eyes, using them to properly assess an opponent's actions and respond accordingly. Itachi is very adept with standard genjutsu, and can trap others within an illusion by merely pointing or looking at them,[47] as well as turn their own genjutsu against them. He is also noted to be extremely fast with his techniques and movements, extending to his hand signs and weaponry as well. [48]

Additionally, with his Mangekyo Sharingan, Itachi can utilize three specialized eye-techniques. With the first, Tsukuyomi (月読?), Itachi is able to torture opponents for what seems like days in a matter of moments. Amaterasu (天照?), the second, generates black flames at Itachi's focal point that will continue to burn until the target is reduced to ash. His final and strongest ability, Susanoo (須佐能乎?), creates a massive ethereal warrior that will fight on Itachi's behalf, and otherwise shields him from all attacks. Zetsu notes that Itachi has equipped Susanoo with two legendary artifacts that give it additional abilities. Each ability is progressively more taxing for Itachi to use, such that after performing Susanoo he starts coughing up blood. After a prolonged battle with Sasuke, Itachi collapses and Zetsu, who had been observing, states that he's dead.
