Currency Demon, 5Heart Demon
Kakuzu was a tall, tanned, muscular man that towered over everyone in Akatsuki with the exception of Kisame Hoshigaki. He wore a white hood and a black mask, with his eyes being the only visible part of his face. Underneath, his mouth was stitched together at the edges and he had long dark brown hair. His eyes have an unusual colouring: green irides, no pupils and red sclera. His clothing included the traditional Akatsuki cloak and the forehead protector of his home village with a scratch in the middle which symbolised that he was no longer loyal to it. He also wore dark green nail polish and an Akatsuki ring with the kanji for North (北, hoku) was placed on his left middle finger. His entire body was covered with various stitches and predominantly appeared to be sewn together. This was a result of the unique technique that he possessed —the Earth Grudge Fear.
Kakuzu was a greedy, miserly individual, arranging goals in terms of the highest profit he could gain from them, and was often unwilling to involve himself in something if there was nothing to gain from it, as well as claiming that he tended to forget opponents who were not worth any money after he was done with them. He even remarked that money is the only dependable thing in the world. Due to this end, he referred to himself as the "Treasurer of Akatsuki". Given his friendly relationship with Zangei, his bounty officer, it would seem he collected bounties rather frequently to earn cash, and did so (or at least tried) during his missions on several occasions. The frequent side-tasks and devotion to money were both major points of contention between Hidan and Kakuzu. He also seemed to respect an opponent who thinks, as shown with his reaction to Kakashi's counters to Kakuzu's masks, and Shikamaru's quick analysis of Hidan's curse, even mentioning Shikamaru would have been a good bounty in the future.
Out of all the Akatsuki members, Hidan and Kakuzu displayed the most animosity towards each other, since neither of them were very fond of each other's interests. The two often traded barbs with one another, Kakuzu's usually having better timing than Hidan's. Hidan had shown great annoyance with Kakuzu's greed and occasional habit of doing or saying blasphaemous things, such as attacking a temple and killing the head monk for the bounty on the monk's head. Kakuzu, in turn, disliked Hidan's religion, believing the rituals associated with it to be a waste of time. Kakuzu was also rather impatient with Hidan's drawn-out speeches and battle style. Despite their mutual dislike of each other, their teamwork was almost flawless, because they complemented each other's abilities extremely well.
The only reason that Kakuzu put up with Hidan was because he couldn't get rid of him. Due to his violent temper, Kakuzu often killed anyone close by when enraged. Hidan, therefore, was the perfect partner for Kakuzu, because of Hidan's inability to die. Kakuzu's somewhat indiscriminate attack style also made Hidan an ideal partner, since Kakuzu didn't need to worry about catching his partner in the crossfire.
Despite his obsessive personality and violent rages, Kakuzu was much more cautious than his partner, and was not as arrogant, never mindlessly rushing into battle like Hidan. Kakuzu frequently warned Hidan not to let his guard down, and then teased Hidan when he inevitably did. Kakuzu also seemed quite willing to follow orders. When ordered to retreat by the Akatsuki leader, Kakuzu complied immediately (while Hidan attempted to argue), despite the rather large bounty he could have received by taking Asuma. He seemed to forget the greater goals of the organisation when enraged, as he attempted to kill Naruto, in spite of Akatsuki's need to capture all the jinchūriki alive.

When he was still a loyal, elite ninja of Takigakure, Kakuzu took on a mission to assassinate Hashirama Senju, the First Hokage. This mission, however, ended in failure due to the might of Hashirama's Wood Release techniques. Despite the insurmountable danger faced in the mission, what awaited his return to his village was the stigma and harsh punishment associated with the failure of his objective. In response to this treatment, a wrong levied against a shinobi who had put life and limb on the line for his village, Kakuzu came to hold a violent hatred to his village as he escaped from imprisonment. In his flight from the village, Kakuzu killed the village elders, took their hearts, and fled with knowledge of the village's most prized forbidden techniques. He made a living off bounty hunting in the black market, and tearing out the still-beating hearts of powerful shinobi to extend his own lifespan. Some time after his defection, he joined Akatsuki, and was given a number of partners, most of whom he killed, due to his short temper. This is why he was eventually partnered with Hidan, whom he could not kill because of his immortality.
Also at some time in the past, he apparently encountered the Gold and Silver Brothers and witnessed Kinkaku's jinchūriki transformation.
Hidan and Kakuzu arc
Kakuzu first appeared with his partner, Hidan, in their pursuit of the Two-Tails' jinchūriki, Yugito Nii, who revealed she allowed herself to be cornered, in order to spring a trap on them and eliminate them herself. Yugito then transformed into her full demon form, a large flaming cat, but the Akatsuki duo still managed to defeat her, and gave her body to Zetsu, before they continued to the Land of Fire.
On their way, Kakuzu decided to attack the Fire Temple, in order to collect the bounty on the head monk, Chiriku, who was listed in the bingo book with a thirty million ryō bounty. They slaughtered most of the other monks during the event, but one escaped to warn Konoha of the incoming threat.
Upon receiving the notice, Tsunade assigned the Nijū Shōtai to track down and eliminate Kakuzu and Hidan. Meanwhile, Kakuzu took Chiriku's body to a bounty station hidden in a bathroom, while Hidan chose to wait outside. When Kakuzu finally left the bathroom after counting the money, he found a Nijū Shōtai team, led by Asuma Sarutobi, attacking Hidan. He attacked Shikamaru Nara in order to free Hidan, but was forbidden from further participation in the battle by the overconfident Hidan himself. Kakuzu complied, but insisted that he would get to have the thirty-five million ryō head of Asuma afterwards. In the ensuing battle, Hidan managed to ingest Asuma's blood to start his curse technique ceremony on him, but Shikamaru was able to stop him with his Shadow Imitation Technique. When Asuma managed to decapitate Hidan, Kakuzu finally intervened, and reattached Hidan's head back to his neck using the threads in his body. Kakuzu then fought with Kotetsu and Izumo, easily holding the two off, while Hidan dealt a fatal blow to Asuma. Their battle was interrupted by the appearance of another Nijū Shōtai team, but they easily fought them off, until they were summoned by the Akatsuki leader to seal the Two-Tails. Hidan and Kakuzu retreated to a secluded area, where they spent three days sealing the Two-Tails (and in the manga, another three days sealing the three-tails)
After the sealing was complete, Kakuzu and Hidan set out on their search for the Nine-Tailed Demon Fox's jinchūriki (Naruto Uzumaki), only to be cut off by Team 10 (with Kakashi Hatake as the leader in place of Asuma). Shikamaru used Asuma's chakra knives to capture both the Akatsuki members in place with a trick, but Kakuzu had discovered the trick beforehand, and, using a separated arm, broke free. Because of his ability to harden his skin, Kakuzu proved to be largely invulnerable to subsequent attacks. Kakashi, however, was able to analyse Kakuzu's hand seals, and pierced Kakuzu's heart with his Lightning Cutter, exploiting the weakness Kakuzu's earth-based technique had against lightning-based techniques.
While this would normally be fatal, Kakuzu had five hearts (now four) in his possession, and thus recovered fairly quickly, sending a counter-attack to Kakashi. Removing his cloak, he revealed four masks on his back, one of which was now broken by Kakashi. Each mask contained a heart, the broken one having given its heart up to keep Kakuzu alive. The four masks broke free from his back into separate entities, with the broken one dissolving after doing so. Each mask was able to attack with a specific and powerful elemental attack, making Kakuzu almost too much for Team 10 to handle. While Kakuzu set his sights on replacing his lost heart with Kakashi's, Shikamaru dragged Hidan away from the battlefield into some woods, with his Shadow Imitation Technique, for a one-on-one fight.
Ignoring the other two for the most part, Kakuzu focused on taking Kakashi's heart. Though Kakashi was unable to handle Kakuzu and his mask creatures, being forced to protect Ino and Chōji too, he was saved when Shikamaru tricked Hidan into using some of Kakuzu's blood in his curse ritual, which Kakashi had collected in a capsule earlier when he pierced Kakuzu's chest, and had handed it over to Shikamaru. This resulted in Hidan unintentionally destroying Kakuzu's main body's heart. Seeing this, the Lightning mask allowed its heart to be absorbed by Kakuzu's body, bringing him back to life. In addition to that, Kakuzu also had the two other Fire and Wind masks to combine with him, making him even more powerful. He then caught the rest of Team 10 with his threads, hoping to replenish his stock.
Team 10 was saved by the arrival of Team 7, among them being Naruto, who decided to fight Kakuzu himself, who at first did not view Naruto as a threat. This changed when Naruto unveiled his newly developed technique, Wind Release: Rasenshuriken, which Kakuzu recognised to be dangerous if it ever connected with him. Naruto's inability to maintain the technique for more than a few seconds put Kakuzu at ease, especially since its failure almost allowed him to kill Naruto (although Yamato and Kakashi saved him), but decided to fight in his long-range mode just to be safe. As Naruto tried the Rasenshuriken once again with his shadow clones, Kakuzu attempted to crush Naruto with his threads from a distance, but was surprised to discover that it was a shadow clone that he had destroyed, and, subsequently, the real Naruto shot up behind him, using the technique effectively this time.
Lightning Mask- This Heart has the Lightning affinity and takes on the shape of some sort of deformed biped. It is able to use Lightning style false datkness and other lightning based techniques.
Water mask- This Heart has the water affinity and takes on the shape of a long, slim dragon with large, wide wings and thin, short arms and no legs. It is able to use several different water style techniques.
Kakuzu has demonstrated great raw speed, he is able to cross great distances in the blink of an eye and disappear from unfocused eyes. He was fast enough to be able to intercept Kakashi when he was attacking Hidan with his Lightning Cutter. His raw strength was great enough to catch one of Chōji's enlarged punches with a single hand and punch down an iron gate, as well as lifting and choking two people simultaneously. This was further supplemented by his already adept taijutsu skills, shown when, during his fight with Kakashi (who is quite skilled in taijutsu) he mixed his hardening and extending abilities with his taijutsu eventually overwhelming Kakashi himself. All these factors afforded him great versatility against his opponents.
