"Even Hell runs on money. I'd be just fine."
Bounty Hunter, Earth Grudge Monster
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, Takigakure with a scratch in the middle which symbolised that he was no longer loyal to it. His entire body was composed of stitches and dark threads, this was a result of his stolen Kinjutsu - Earth Grudge Fear.
There are countless scars and stitch marks on Kakuzu's body. It is evidence of the untold times he has returned from the threshold of death.
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 blasphemous 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.

Kakuzu's Signature Jutsu
(Jiongu: Kuro Ito) - Earth Grudge Fear: Dark Threads
Rank: C-S Rank
Chakra Cost: 15-40
Damage Points: 30-80
Description: The basic technique of Kakuzu's unique Kinjutsu Earth Grudge Fear it allows the user to manipulate the threads that compose his body freely with each use. The user can not only alter his own body form and structure but also use the threads to attack or defend from incoming techniques. As Kakuzu's skin is still stitched to keep his humanoid form when not used, he can take advantage of this technique to propel his hands or limbs at great distances and grab a target. Its also this technique that allows Kakuzu to detach his masks from his own body to form the "animals" which he uses in combat.
Note: Can only be used by Kakuzu
(Doton: Domu) – Earth Release: Earth Spear Technique
Chakra cost: 20
Damage points: N/A (+10 to physical attacks)
Description: After performing the Snake hand seal the user will channel their chakra throughout their entire body, which then hardens their skin to a steel-like quality. This increases their defensive power to the utmost limits. The user’s skin also becomes much darker, an almost black colour. The destructive power of physical attacks is increased, making this a great, all purpose technique. But this technique when activated leaves the user vulnerable to lightning based techniques.
Note: Kakuzu bios can use this technique without the need for handseals
(Shinra Banshō Dōka No Jutsu) - Assimilate All Creation Technique
Chakra Cost: 15
Damage Points: N/A
Description: The user can take on the properties of any earthen material they touch and harden any part of there body. This jutsu also lets the user turn into fine grains of rock that can be used to do another jutsu. The issue with using this technique is that the user will gain all the weaknesses of the material they mimic, even if they are granted their strengths.
(Jiongu: Saishu Shageki) Earth Grudge Fear: Final Shot
This is one of Kakuzu's ultimate techniques. Once he has gained access to a Lightning, Fire and Wind hearts, he can use this technique. Without having released them from his body, Kakuzu puts forth his hands and produces a mash of Dark Threads from them from which the 3 masks manifest and protrude. As they open their mouths, they each produce an A-Rank elemental stream of their own element (Lightning, Fire and Wind) that combines into a massive attack. However, because of the elemental interactions, although its high chakra cost, the final damage is equivalent to an S-Rank technique. The main difference is that its an S-Rank with 3 simultaneous natures, making countering it quite hard.
Note: Usable twice per battle.
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 on 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 for 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 on the black market, and tearing out the still-beating hearts of powerful shinobi to extend his own lifespan.
Kakuzu, soon after his defection from Takigakure decided to join Akatsuki, a criminal organization which made his lifestyle much easier due to targets with high bounties commonly always being situated nearby to Jinchurikis they had to take down.
Whilst a part of Akatsuki, it is said that until he found a partner who wouldn't die, he slaughtered every partner he had when enraged, as well as cutting out their hearts to supplement his own abilities. This clearly shows that beneath Kakuzu's mask and cool demeanor lies a seething rage for everyone and everything.
His 91 years of life experience led him to encounter and battle many shinobi in his life time, The Gold and Silver Brothers and Hashirama Senju both being clear testaments to this.
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 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.
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 ones.
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 recognized 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.
- Due to possessing a natural affinity to the Earth element, after mastering it, Kakuzu's become capable of performing all Earth Release techniques (which require handseals) with faster handseals.
- Over the years Kakuzu began to develop a liking to the Water element due to its calm and fluid yet destructive nature. As a result, after attaining complete mastery of the element, he's become capable of using all Water Release techniques (that require handseals) with a single handseal.
- Kakuzu possess the Boar Ring and wears it on the little finger of his left hand. The ring further augments his earth manipulation abilities, increasing the strength all of his Earth jutsus by 10 and using them with 1/3 of the handseals usually required.
Dark Webbed Arts
- Being a master of his signature fighting style, Kuro Amminono Gigei, Kakuzu has attained levels of agility slightly higher than that of a Taijutsu specialist.
During his life Kakuzu explored a wide range of abilities as his life as a bounty hunter, before coming across Ling Yao. Shortly after meeting the man, he was allowed to sign his infamous Ray Contract. Signing the Ray contract meant he could summon any of the rays to battle at any time to aid him. From signing the contract he was gifted with a special tattoo on the underside of his left wrist, making summoning the creatures a quicker process.
Kakuzu, after coming across the owner of the Eel contract was allowed to sign these fearsome creatures. As a result, he become capable of utilizing jutsu associated with the contract and is able to summon them to battle at any time to aid him. From signing the contract he was gifted with a special tattoo on the underside of his right wrist, making summoning the creatures a quicker process.
: Kakuzu carries a whole multitude of weapons. In his ninja pouch, he carries shuriken, explosive kunai, explosive tags, flash and smoke bombs, ninja wire, and all the other items essential for a ninja. He also carries a basic black scimitar on strapped to his left hip which can be wielded with one hand. Other non-conventional weapons he carries include: a pouch full of fine sand, gas mask, some cigarettes and flint.
: Kakuzu being a keen user of Earth Release carries many topography scrolls, both blank and ready-made. His ready-prepared scrolls consist of three designs. The 1st causes a large maze with thirty meter tall walls to be created. A unique feature about the maze is the spikes protruding from the top of each wall, preventing anyone from mounting themselves on the wall.
The 2nd design causes a castle fully equipped with two tall watch towers to be summoned.
The 3rd and final scroll has a prepared design of tall walls which curve at the top, forming a massive dome which encases everything inside. The diameter of the dome is expansive and once completely formed, its pitch-black inside making it impossible to see anything at all.
All of these topography scrolls are used for "Earth Release: Wheel of Fortune" and the ready-made scrolls are carried in separate pockets.
Will of the Bloody Mist
- Being a member of Kirigakure, Kakuzu has become all too acquainted with blood shed. He holds a firm belief that invaluable information takes precedence over the lives of comrades, and will show no remorse in killing his allies for the sake of the mission. He often comments that "the mission is absolute".
Hearts captured from other ninja granted Kakuzu numerous elemental affinities, along with a vast supply of chakra. By collecting these hearts Kakuzu's own affinity is reinforced and his skill in other elements is increased to the point that he was able to use various different elemental attacks that were noted to be impossible, without having an affinity to that particular element.This is done by connecting his chakra circulatory system to his four extra hearts, granting him the ability to change his chakra nature and affinity to that of the previous owner. The individual hearts could be released from his body and wrapped in a vast blanket of threads, forcing a heart into a limb before being detached or forming a monstrous body with a mask as its face. These masks could move and attack independently, unleashing powerful blasts of elemental chakra from their mouths, allowing them to use all techniques of their respective element without using handseals. The raw power of each element Kakuzu demonstrated even made Kakashi, who is also capable of multiple elements, stiff with awe.
After Kakuzu steals a heart he converts it into a mask and mutilates himself in compensation, forcing this new heart to become a part of his body.
Kakuzu's animal masks, which resembled those of ANBU, contained his spare hearts. If he took use of the heart for himself (if he somehow died during combat), the corresponding mask would shatter upon the creature's re-entry into Kakuzu's body. As a result, he would take on the affinity of that mask and lose the affinity of his original heart.
- This Heart has the Fire affinity and takes on the shape of some sort of demonic tiger who stood on two legs. It is able to use Fire Release: Intelligent Hard work and all other fire release techniques the user knows. This mask's face was painted a crimson red by Kakuzu to signify its the Fire mask.
- This Heart has the wind affinity and takes on the shape of an alligator like creature. It is able to use Wind Release: Pressure Damage and all other wind release techniques the user knows. This mask's face was painted a jade-green to signify its the Wind mask.
- This heart has the lightning affinity and takes on the shape of a tall humanoid figure. Its able to use Lightning Release: False Darkness amd all lightning release techniques the user knows. This mask's face was painted a goldish-yellow to signify its the Lightning Mask.
- This heart has the water affinity and takes on the shape of a bear-like creature, but its face resembles that of a piranha. Its able to use all Water Release techniques the user knows. This mask's face was painted a dark-blue to signify its the Water mask.
All of Kakuzu's Masks are capable of flight, can integrate back into his body at will and can act remotely once they've reintegrated back into his body. His hearts once reintegrated will act from either his shoulders or his back. Kakuzu's main heart possess the Earth affinity, giving him a total of five hearts.
This merging ability isn't limited to merging back into Kakuzu's body, but also combining their own bodies to amplify their attacks greatly, as shown when Kakuzu's Fire and Wind Hearts combined to become a truly destructive force. Furthermore, Kakuzu has developed the ability to partially release his masks, allowing them to extend out of his body without fully detaching, whilst retaining their capability to perform techniques, in a similar manner to the Soma No Kou.
Kakuzu's Elemental Masks (attached to his body)
Kakuzu's Elemental Masks (Released)
Chakra: N/A (-10 per turn)
Description: Vengeous is a large sentient sword created by Kakuzu himself using his dark threads and the heart of a fallen foe. The sword itself is two meters in length (including the hilt) and is the same width as a compacted Samehada. The entirety of the sword is composed of spiky black threads, and the exterior is tightly weaved together into a dense structure, which is impossible to cut through by normal means. The hilt of the sword is constructed of pure jade and shape of the blade of itself looks much like a curved arrowhead with its tip resembling a crab’s pincer. The heart inside of the sword is located in the center of the blade and is fully functioning, resulting in Vengeous being considered both a living creature and a sentient ally to Kakuzu. As a result Vengeous is capable of acting of its own accord, rational thought and has a malicious personality inherited from Kakuzu. The sword itself can go weeks without nutrition and has a strict diet of blood which it ingests through its skin. The sword is usually carried around in a black and red scabbard, on the user’s back.
-The sword is near impossible to break/cut through due to it’s tightly weaved exterior.
-The sword is capable of extending dark threads as tendrils to restrict and ensnare the opponent. These tendrils are capable of reaching up to five meters (short range) and can come from anywhere on the blade. The tendrils can pierce the bodies of other shinobi, can prevent the opponent's mobility by wrapping around them or even disarm a foe of their weapon. The amount of tendrils that can be released at any one time varies between 8 and 16. The tendrils themselves are each about the same width as a basic rope (ten centimeters) and all have sharp pointed ends. This is a B-Rank Ability
-The sword is capable of shooting out countless needles composed entirely of dark threads, which are about thirty centimeters in length and five times the width of a normal senbon. The needles can be shot from anywhere on the blade and have a mid-range reach (10 meters). This will count as one of the user’s jutsu per turn. This is an A-Rank ability
-The blade possess the ability to extend spikes from everywhere on the blade or hilt at any time, which are capable of skewering through the body of anyone they come into contact with. The spikes can reach up to two meters in length. Spikes which emerge from the blade resemble basic spears in both shape and width and the end result makes the sword look like its coated in an armour of spikes. Spikes which emerge from the hilt are much smaller, resembling needle-like thorns in shape and width. The spikes can be released at any time, adding a further element of surprise to the wielder's fighting style. Shortly after release the threaded spikes re-enter the sword, restoring the weapon's ordinary shape. This is an A-Rank ability
-The blade can use a limited amount of the elemental chakra present in its heart. It can use it to unleash blasts of pure elemental chakra (of the main elemental affinity of that heart) in various forms as both streams, blasts, projectiles, crescents, etc by swinging the sword. The sword can only use one element which is the main element of that heart. This ability is S-Rank.
-The sword is capable of crawling and acting independently
-Kakuzu is unable to use the heart of this sword for "Heart Reaper"
-The sword possess no mouth and isn't capable of talking but it does communicate with the wielder in an unknown form
-Must have a Kakuzu bio to wield the sword
-Vengeous is incapable of transferring chakra to the wielder
-The Sword can be killed by being burnt, melted or severely shocked. This makes the weapon extremely prone to death from Fire, Lightning and similar attacks, specially S-Rank and above.
-Negative Knight is the only person capable of wielding this weapon. In response to anyone else who attempts to wield the blade, the sword erupts in a violent outburst, extending 10 meter spikes from everywhere on its body (including the hilt), severely impaling the unsuspecting wielder.
-The 4 main abilities of the sword count as moves from the users move count and each can only be used 3 times.
-If the sword is severely damaged, the user can give it a heart and renew it.
How the Sword Looks
Kakuzu carries Raizu, his faithful weapon into everywhere he goes and into all of his fights. The sword is strapped to his back (without a scabbard) and can be withdrawn with the slightest whim. The heart located in the blade possess the Wind affinity, allowing it to utilize fuuton-based techniques at the users will.
The ring increases the earth manipulation abilities of the user: Earth technique strength is increased by 10 and 1/3 hand seals.
-The stone on each ring is indestructible.
-The stone has a jade-green color.
-Kakuzu wears the ring on the little finger of his right hand
-The abilities can only be used by the wearer. And aren’t active unless the worn on the proper fingers.
Skill and Experience
Kakuzu was a very powerful ninja, strong enough to become a member of Akatsuki. During his frequent rages, Kakuzu has killed many of his former partners in the organisation. A further testament to his skills was his survival in a battle against Hashirama Senju, many years before his acquisition of the Earth Grudge Fear technique, despite ending up unable to complete his assassination mission. He had extremely high combat prowess and a vast array of techniques (due to his unique Earth Grudge Fear technique and near a century worth of experience). Those traits allowed him to fight several opponents while generally controlling the pace of the fight, including Kakashi Hatake with Chōji Akimichi and Ino Yamanaka as backup, and would have possibly killed them, had it not been for the additional assistance from Team Yamato.
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 all of which afforded him great versatility against his opponents. Using Earth Release: Earth Spear Technique he was able to increase his hardness, up to the point when he was able to withstand attacks that were normally fatal, an example being him able to withstand Choji's surprise ambush without any visible damage.
Unique Bodily Composition
All of Kakuzu's abilities revolved around his unique body structure, which was composed of hundreds of thick, grey tendrils woven throughout his flesh called Earth Grudge Fear, holding his body together like the stitches of a rag-doll. This allowed him to separate his body parts at will, to perform long-range physical attacks and sew up almost any injury he suffered. All these abilities made him very difficult to defeat. The threads could also be used to repair the bodies of others, as seen when he reattached Deidara's arms, although Hidan's inability to die after being dismembered caused him to be Kakuzu's most frequent patient. Because of his unique body structure, Kakuzu is a highly enduring man, able to take a direct strike from Kakashi's Lightning Cutter without it hindering his performance. His threads could even compact together to form a giant octopus-like form around his body, used for long range battle.
Threaded on a Molecular Level
Kakuzu's threads granted him a degree of immortality. The threads could pierce the flesh and bodies of others, allowing him to remove their organs and integrate them into his own body, thereby extending his life. He commonly removed hearts in this fashion, keeping a total of five at any time, and requiring that he be killed at least five times in a battle before he truly died. If Kakuzu was killed somehow, then one of his extra hearts could then re-enter his body and bring him back to life at the cost of the hearts.
With his unique body structure, he has shown himself capable of extending his limbs a considerable distance from his body, use them as a restraint mechanism, repair his own wounds and using them to latch onto parts of the terrain in quick succession, as displayed through his final fight with Naruto.
Kakuzu's manipulation of his dark threads also branched out into releasing threads from almost anywhere on his body in an attempt to capture or ensnare the opponent. This ability aids him in close combat situations and is useful in ensuring critical blows when used in conjunction with ninjutsu. Kakuzu displayed this tactic against Kakashi and Team 10 in an attempt to incinerate all of them at once. When paired with his brute strength and his thread's natural ability to extend/retract a whole array of possibilities are opened up to Kakuzu, allowing him to perform complex Taijutsu attacks, throws and grapples.
With his unique body structure Kakuzu could also release a mass of threads from his body to enter various forms. In those forms he could control threads from anywhere on his body. His long range mode also had the added advantage of allowing him to keep a safe distance from his opponent.
Furthermore, Kakuzu could survive being impaled, stabbed or cut into due to his body being constructed entirely of threads. Combined with his ability to sew up injuries with his threads, he could survive seemingly lethal wounds afflicted on him, by stitching up the wound(s) made in his body.
One final ability granted to Kakuzu by his unique body structure was the ability to integrate his limbs underground. This wasn't strictly limited to integrating into the ground whilst connected to his own body, but also the ability to detach and reattach his limbs at will, using his dark threads as a medium to reattach his lost limbs and sew them firmly back onto his body without hindering his performance. This skill was displayed when he used his hand to remove a shadow-enhanced trench knife that prevented the rest of his body from moving.
Kakuzu was shown to be a keen analyst, which was somewhat attributable to his age. He is highly observant, easily noticing that Shikamaru was taking his time to formulate a plan to counter Hidan's technique, after the former caught his partner in his Shadow Imitation Technique. He was able to quickly discern the purpose of Shikamaru's various shadow attacks, and devised ways to counter them almost instantaneously during the battle. An example for that is when Shikamaru trapped him and Hidan in his Shadow Imitation Shuriken Technique, Kakuzu detached his right arm, hid it underground and with its help, was able to remove the trench knife, thus successfully breaking free from the technique
Even before his acquisition of his village's Kinjutsu (Earth Grudge Fear), his village thought enough of his abilities to send him to assassinate a man with such overwhelming power that today his legend is believed to be fabricated. Even without a large portion of his current arsenal, Kakuzu was seemingly able to make do with the basic skills he possessed in order to survive against Hashirama's wrath.
Furthermore, Kakuzu's fighting style often involved analyzing his opponent's abilities/fighting style whilst simultaneously concealing his own. When he gathered enough information, he would proceed to exploit weaknesses in their style and use his own arsenal to construct effective counters.
Kakuzu has walked the path of a shinobi for a long time. The ability to last for so long is his innate ability to naturally work out how capable a foe is. As he tenaciously clings to life, he has honed his analytical skills to work out whether or not a heart is worth taking and if he's physically capable of doing so. Kakuzu's abilities backed up by extensive knowledge and experience is especially useful when working within a team, allowing him to pool all resources available to him and use them to their utmost effectiveness.
