Kakuzu was a tall, muscular man, second in height in Akatsuki (after Kisame Hoshigaki). He wore a white hood and a black mask on his face with his eyes being the only visible part. Underneath, his mouth was stitched together at the edges, and his hair was long and untidy. His eyes have an unusual coloring: green pupils and red scleras. His clothing included the traditional Akatsuki cloak and the forehead protector of his home village with a scratch in the middle which symbolized that he was no longer loyal to it. He also had dark green nail polish and his Akatsuki ring with the kanji for North (北, hoku) was placed on his left middle finger. His entire body was covered with stitches and appeared to be sewed together. This was a result of the unique jutsu that he possessed - Earth Grudge Fear. On his back were four masks each resembling those of ANBU where he stored his additional hearts.
Hidan has medium length silver hair slicked back with distinctive pinkish-purple eyes. He wears his Akatsuki cloak open with no shirt, only pants under it revealing his Yugakure forehead protector around his neck and Jashin amulet. He wears dark green nail polish and his Akatsuki ring on his left index finger, which bears the kanji for Three (三, san). He is always seen with his Triple-Bladed Scythe on his back. His left ear also appears to be torn or cut after his fight with Asuma. Also, after his battle against Asuma's unit, he did not replace his torn Akatsuki robes.
Konan is stoic, calm, and level-headed (much like her partner, Nagato, was). As a child, she was bright, compassionate, and relatively cheerful, in comparison to Yahiko's tough attitude and Nagato's sensitivity. However, the trauma of events since then have led her to become a very serious person, and she never spoke during Akatsuki meetings. Nevertheless, she has always placed the safety of her teammates above her own.
She does seem to be more empathic than most other Akatsuki members, as she appears sad whenever she has been reminded of her past. She also expressed a great deal of loyalty and courtesy to Pain, doing his bidding without question, looking out for his well-being and always having complete faith in his abilities. She seemed to act as an intermediary between Pain and Amegakure, the villagers having given her the title "God's Angel" for this reason, and for the reason that, with her paper wings activated, she looks like an angel.
She had the ability to read Pain's emotions without him facially expressing them, presumably as a result of having known him for so long. As soon as Madara Uchiha ordered Pain to capture the Nine-Tailed Demon Fox, she could tell right away that there was something about the order that very much upset her emotionally deadened partner.
According with his two differently colored halves, Zetsu seems to have a split personality, as in the Japanese version of the manga, the black half of his face only uses Katakana for Okurigana and Furigana while the white side uses Kanji and Kana regularly, and in the English episodes, the black side has a different voice actor than the white side. The two halves also converse with each other, and occasionally differ in opinion (the black half is more serious and intelligent while the white half is carefree, easygoing, and seems to enjoy toying with others).[2] They also seem to communicate through their thoughts.
Zetsu is seemingly very trustworthy, being entrusted with knowledge of Pain and Tobi's true identities. He has apparently been working with the latter for some time, Tobi first appearing as his "subordinate" and Zetsu later commenting that Tobi's plans had been in the works for a long time. The character showed some lust for money when he quoted Kakuzu on his principle that money is most important however whether or not this applies for both personae is as of yet a mystery to be dealt with. Zetsu's white side has also shown to be very confident in himself as he was willing to fight Naruto despite knowing Pain had lost in battle against him.
Zetsu's main role within the Akatsuki is to function as a spy, and often performs duties that are similar to a hunter-nin. He has been shown able to move his body and take part in the tailed beasts sealing ritual simultaneously which, in addition to being unique to him, allows him to act as a lookout while the sealing takes place.[3] When an agent to Akatsuki, or possibly even a member, dies, Zetsu is sent to devour their bodies so as to not have their secrets revealed, which adds further his venus fly trap theme.[4] Zetsu is also the one sent to retrieve the rings of dead Akatsuki members.[5] Due to the role he plays, Zetsu is the only member of Akatsuki to act without a partner on a regular basis. Despite this, Zetsu serves as a sort of superior to other members, as they often reported directly to him instead of to the actual leader, Pain.[6]
Ever since his first appearance, Itachi had always been mysterious, and had acted as though he was hiding his true self. While flashbacks to his past showed that he was a compassionate brother and person, his later acts and claims made it seem that this was mostly just an act. But, surprisingly, he genuinely was the compassionate brother he had once claimed to be, although he hid this from the rest of the Akatsuki to protect Sasuke.
As a member of Akatsuki, he possessed incredible self-control of his emotions. He constantly displayed an emotionless personality. He only showed surprise when opponents proved more powerful or skilled than he had expected, and even then he didn't lose his composure. He did not possess any arrogance, and fully justified any statements he made about his power, even complimenting his opponents at times on their abilities.
In addition to being an extremely powerful ninja, Itachi had equally impressive intelligence, and was shown to be very wise. He was exceedingly sharp and observant to any situation at hand, as he was rarely surprised or caught off guard. He also displayed great intuition, as he was almost never deceived and even then almost instantly realized the truth. Despite his status as a wanted criminal, and having wiped out his clan, Itachi took no enjoyment in violence or combat, instead preferring to avoid battle or, if this was not possible, end it as quickly as he could.
Itachi's only initial interest was in Akatsuki's goals, and his only loyalties appeared to be to the organization and its members, seeming to put the organization's success and secrecy before everything else.[5] As such, Itachi got along with his partner, Kisame, much better than most other Akatsuki members did with their own partners. Kisame appeared to have a deep loyalty to Itachi, immediately doing as he instructed and constantly looking out for his well-being. Itachi treated all of his fellow Akatsuki members to this same, more respectful personality, although his courtesy was rarely returned by the other members.
However, when he was in a genjutsu duel during his fight with Sasuke, he cruelly claimed he had only let Sasuke live so that he could take Sasuke's eyes and obtain his own Eternal Mangekyō Sharingan, after which he then claimed the Uchiha clan had been nothing but tainted and evil, since many members would kill their friends to gain the Mangekyō Sharingan, and would take another Uchiha's eyes to make its power permanent. Once the genjutsu was released, he called it his true self, implying his calm, emotionless personality was also a facade. This persona was later revealed to be only an act to ensure that he would die by Sasuke' s hands, his love for his younger brother being the fundamental aspect of his personality.
In the end, Itachi put all of his faith in Naruto, who he notes as the person most determined to save and protect Sasuke. After hearing Naruto's answer to keep protecting Sasuke and everyone in Konoha, Itachi gave him some of his power. He was very grateful towards Naruto's determination to save Sasuke, and was smiling after hearing Naruto's response. Itachi even trusted him enough to bring Sasuke back to the light.
