Hidan , Hidan is the foul-mouthed partner of Kakuzu and a former ninja of a yet-to-be-identified village. He is a member of the Jashin (, Jashin lit. "evil god") religion, a religion that worships a deity of the same name and where anything less than death and utter destruction is considered a sin. His religion seems, to some extent, to extend to his unique abilities; by consuming an opponent's blood and then drawing Jashin's triangular-design on the ground, Hidan can create a voodoo doll-like link with his opponent. Once this link is created, any damage done to Hidan's body is reflected on his opponent, allowing him to kill them by giving himself fatal injuries. Because he is immortal, Hidan is not impaired while doing this, instead finding pleasure in the pain it causes him. After Hidan uses this ability to kill Asuma Sarutobi, Shikamaru Nara fights him to avenge his teacher. Their battle culminates in Hidan being blown up, and Shikamaru buries his still-speaking remains in a place Akatsuki will never be able to reach. As such, Hidan is no longer considered a member by the rest of Akatsuki.
Throughout the series Itachi attempts to avoid combat, seeking nonviolent discussions instead. If he is forced to battle he usually remains stationary, only acting in self-defense. From his idle position he studies an opponent's movements with his Sharingan eyes, trapping them in illusions when opportune by merely pointing or looking at them. He is noted to be extremely fast with hand movements, allowing him to attack before an opponent has the chance to respond.. Itachi at times uses one of the three abilities of his Mangekyo Sharingan, though he tries to avoid doing so as it is taxing on his body and damages his eyesight. The first, Tsukuyomi, Tsukuyomi, allows him to torture opponents for what seems like days in a matter of moments. Amaterasu , Amaterasu, the second, generates black flames at his focal point that will continue to burn until the target is reduced to ash. The final ability, Susanoo , Susan, creates a massive ethereal warrior that fights on Itachi's behalf and shields him from all attacks. Before he dies during his battle with Sasuke, Itachi implants a single Amaterasu in Sasuke's eyes, hoping that doing so will eventually kill Madara Uchiha.
KAKUZU
Kakuzu , Kakuzu is a former ninja of Takigakure and the partner of Hidan. He has a deep love for money, and uses his membership in Akatsuki as a means to seek out valuable bounties. Because money is the only thing he relies on, Kakuzu dislikes needing to be partnered with someone in Akatsuki. He has killed all of his previous partners in fits of rage, and thus was paired with the immortal Hidan so he wouldn't need to keep finding a replacement. Kakuzu's body is composed of large amounts of black threads, allowing him to sew things (such as Hidan's dismembered body parts) back together. The threads are also capable of piercing flesh, which Kakuzu uses to remove the still-beating hearts of his opponents for his personal use. By integrating these healthier organs into his body he can escape death and extend his life indefinitely. He can carry five hearts at a time. Hearts that he is not using are stored in animal masks sewn to his back. The masks can be detached during combat situations to shoot elemental blasts at his opponents, and can quickly be recalled to his body if he needs their heart. Kakuzu's masks are systematically destroyed soon after his introduction by a group of Konohagakure ninja. After Naruto Uzumaki leaves his final heart on the brink of failure, Kakuzu is easily finished off by Kakashi Hatake.
KISAME
Kisame Hoshigaki , is a former ninja of Kirigakure and the partner of Itachi Uchiha. While most Akatsuki partners are hostile towards each other, Kisame and Itachi get along considerably well; Kisame does as Itachi asks of him unquestioningly and always looks out for Itachi's well-being. While he was still loyal to Kirigakure, Kisame was one of the Seven Swordsmen of the Mist, a group of ninja that use particularly large swords in battle. His sword, Samehada (, Samehada lit. "shark skin"), is covered in scales, can absorb untold amounts of an opponent's chakra, and only allows Kisame to wield it. Kisame has a unique appearance, having pale blue skin, a gill-like facial structure, and sharp triangular teeth. These shark-like characteristics extend to his choice of attacks in battle, as he frequently shapes water into the forms of sharks to damage opponents. If there is no water nearby, Kisame can quickly produce his own lake to use at his leisure.
KONAN
Konan , Konan is the partner of the Akatsuki leader, Pain, and the only female ninja in Akatsuki. She was orphaned as a child by one of Amegakure's many wars, forcing her to fend for herself until being found by Jiraiya. Jiraiya trained Konan to take advantage of her natural talent with origami, and as a result paper is a key component in her battle style. Konan can divide her body into countless numbers of paper sheets, which she controls and reshapes remotely to scout out an area or form weapons for attack. She can even form wings that mirror her title as "God's Angel" amongst the villagers of Amegakure, as she often carries out Pain's (who has the title of "God") will. Her abilities are constrained while wet, as paper clings to itself and loses its stiffness.
MADARA UCHIHA/tobi
Madara Uchiha (, is the founder of Akatsuki and the first possessor of the Mangekyo Sharingan, a rare form of the eye condition unique to the Uchiha. Though it gave him the strength needed to take control of the Uchiha clan, overuse of the Mangekyo Sharingan left him blind, and it was only by taking his own brother's eyes that he was able to regain his sight. Madara eventually banded together with Hashirama Senju to create Konohagakure. The two founders disagreed on who should lead their new village and after a momentous battle between the two Madara was expelled from Konoha. In later years the Nine-Tailed Demon Fox attacked Konoha, an act Itachi Uchiha states to have been Madara's doing, though Madara denies it. Once the fox was defeated by Minato Namikaze, Madara infiltrated Konoha in secret, trained Itachi, and subsequently assisted him in assassinating the Uchiha clan. Kisame Hoshigaki, upon seeing his face, notes him to be the Mizukage.
Much of Madara's role in the series has been under the guise of Tobi , Tobi, who replaces Sasori in Akatsuki after his death. While acting as Tobi he is carefree and goofy as opposed to Madara's usual serious and stereotypically "villainous" self. Tobi's tendency to take credit for other's work and undermine his superiors annoys his partner, Deidara, who either blows up or strangles him in comical fashion as punishment. After Deidara dies during a battle with Sasuke, the only Uchiha to be spared during the massacre, the Tobi persona is temporarily discarded as Madara takes a special interest in Sasuke's development, tending to his injuries after Itachi's death. However, Madara has not completely outlived the use of his guise as he reassumes Tobi's personality on multiple occasions, such as while delaying a group of Konoha ninja.
Though Madara's face as it appeared during Konoha's founding has been shown in full at various points in the series, he always wears a mask in the current Naruto storyline. The mask features a swirl pattern focused around his right eye. His black hair (cut back from his earlier years) is the only constantly visible part of his face. When asked how Madara could have survived since Konoha's founding, Itachi Uchiha states that Madara is immortal. The specifics of his immortality have yet to be touched upon, though Madara implies the potency of his chakra has something to do with it. In battle he has been shown capable of making his body intangible, leaving him visible but otherwise impervious to most forms of damage, and can teleport over great distances at will. In the Japanese anime, the Tobi identity is voiced by Wataru Takagi.
Pain (, is the leader of Akatsuki and the partner of Konan. "Pain" is not a single person, instead being six entirely different bodies that share the same mind. The only common physical characteristics amongst them are their orange hair color, a number of body piercings, and the Rinnegan (, Rinnegan lit. "Samsara Eye"). The Rinnegan, a unique eye condition characterized by a number of concentric circles around the pupil, allows the wielder to utilize any ninja ability. Pain uses it to share visual information amongst all six bodies, giving them the ability to coordinate offense and defense as if they were a single entity. Each body possesses a unique skill; the body with a large ponytail, for example, can summon a wide array of creatures, while the fat body is able to absorb attacks as a form of defense. The six bodies' combined might was enough to singlehandedly overthrow Amegakure's former governmental body, giving Pain control of the village and god-like status amongst the villagers in the process.When first meeting Pain, Jiraiya assumes the entity to have once been Nagato , Nagatoan Amegakure orphan he trained in the past. Though Nagato was the first possessor of the Rinnegan that he encountered and Pain refers to him as sensei, Jiraiya begins to doubt this initial assumption when he sees Pain's six bodies. Realizing that all six bodies once belonged to ninja he encountered when he wandered the Naruto world, Nagato's body not being among them, Jiraiya risks his life to learn the secret of Pain. He succeeds and is able to send his, as yet undisclosed, discovery to Konohagakure, though is killed in the process.
Sasori , Sasori is a former ninja of Sunagakure. His parents died when he was young, leaving him in the care of his grandmother, Chiyo. Lacking the love of parents, Sasori left Sunagakure when he got older and joined Akatsuki where he is initially partnered with Orochimaru. After Orochimaru's defection he Sasori teamed with Deidara, who looks to him and his artistic knowledge with reverence. Before leaving Sunagakure, Sasori was taught the art of puppetry by his grandmother, which he refined to fit his needs over the years. He eventually devised a way to convert the corpses of humans into puppets, allowing him to use any of the ninja abilities they possessed during their life for himself. In time he even converted his own body into a puppet, which gives him eternal life and allows him to control hundreds of puppets at once. Each weapon in his puppets' extended arsenal is laced with a poison of Sasori's design that causes extreme pain to the inflicted until they die. Sakura Haruno is able to create an antidote for Sasori's poison, allowing her and Chiyo to fight him uninhibited. They eventually destroy his heart, the only part of his humanity he kept when converting himself to a puppet, resulting in his death. In the Japanese anime Sasori is voiced by Takahiro Sakurai as an adult and Akiko Yajima during flashbacks to his childhood. His initial puppet body, Hiruko, is voiced by Yutaka Aoyama.
