Itachi Uchiha

Itachi Uchiha 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. His skills were such that his family focused all of its attention on him, ignoring Itachi's younger brother, Sasuke Uchiha, in the process. Over time Itachi began to distance himself from the village and his family, eventually becoming a prime suspect in his best friend, Shisui Uchiha's, death. Before the death could be properly investigated, Itachi killed all the members of the Uchiha clan in a single night so that he could "test [his] ability". Itachi decided to spare Sasuke, however, stating that he was not worth killing; instead, prior to leaving, Itachi told Sasuke to live hating him and to grow strong enough to avenge the clan. At some point in time Itachi joined Akatsuki. While it stands to reason that he joined after massacring the Uchiha clan, the timeline that has been given throughout the series coupled with his age suggests that he joined the organization prior to killing his clan.

Despite his status as a wanted criminal and murderer, Itachi does not display any open enjoyment of violence or combat. Itachi instead prefers to avoid battle or, if that is not possible, end it as quickly as possible while exerting as little effort as he can. 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. His Sharingan is further enhanced when he activates his Mangekyo Sharingan, the strongest ability a member of the Uchiha clan can gain, which he acquired after he killed Shisui Uchiha. With it, Itachi is able to utilize attacks such as Tsukuyomi (月読, literally "Moon Reader"?), a genjutsu that can torture an opponent for what seems like days in a matter of moments. Although these abilities are capable of defeating even the strongest opponents, it has been suggested that he is losing his eyesight as a result of repeated use. Itachi is also very adept with standard genjutsu, and can trap others within an illusion by merely pointing or looking at them, as well as turning 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.
