Kabuto Yakushi

is one of the main antagonists of the series, who was first introduced as a Konohagakure genin. He was later revealed as Orochimaru's personal medic, assistant, and general right-hand man. After Orochimaru's sealing, he joined forces with Tobi during the Fourth Shinobi World War.

Background
As a young boy, Kabuto was found amongst the dead enemies after the Battle of Kikyō Pass by a captain of the Konoha Medic Corps. The captain brought Kabuto to Konoha, raised him as a son, and taught him medical ninjutsu when he got older. At some point in time, Kabuto was recruited by Sasori of Akatsuki, who sent Kabuto to spy on Orochimaru by using Memory-Concealing Manipulative Sand Technique to transform him into a sleeper agent. Orochimaru discovered this, and released Sasori's control over Kabuto's memories, leaving Kabuto with the option to follow him. With a little persuasion, Kabuto agreed to side with Orochimaru.

Kabuto has since used his experience with spying for Orochimaru, playing the role of Sasori's servant to gain knowledge of Akatsuki's plans. Through his affiliation with Konoha, Kabuto was also able to acquire the rank of genin and enter the biannual Chūnin Exams, using the first two parts of the exam to gather information on his fellow participants for Orochimaru's use. Additionally, with the medical expertise taught to him by his adoptive parent, Kabuto is able to carry out human experiments for Orochimaru, while at the same time increasing his own knowledge of the human body.

Personality and Loyalty
Kabuto's loyalties and personality are difficult to discern, as he is a sadistic, yet polite, helpful man with a dry sense of humour. He enjoys playing mind games with his enemies, often unnerving them by pointing out their weaknesses and turning personal horrors against them. During the Fourth Shinobi World War, he freely resurrected people not only for combat, but also to mentally attack his opponents, and saw the personalities of those he brought back as nothing but pawns. Despite this, he seems to have a hard time tolerating rudeness, indicated by his frequent admonishments of Sasuke Uchiha for not treating Orochimaru with respect. Orochimaru also seems to have a hard time determining Kabuto's thoughts at times, as seen when he orders Kabuto to kidnap Sasuke, and wonders if perhaps Kabuto will kill him instead, even giving hints that now would be an opportune time to halt his plans. Even in this instance, Orochimaru has great confidence in Kabuto's loyalty, often laughing at the prospect that Kabuto would betray him.

While Kabuto does generally obey Orochimaru's orders, even going so far as to save Orochimaru's life at times, he is not above helping Orochimaru's enemies; for example, he heals Sakura Haruno and Hinata Hyūga on different occasions. When healing Sakura, Kabuto hints at an ulterior motive, saying that Akatsuki is the true enemy; Orochimaru later says something similar, pointing out that the death of more Akatsuki members means fewer enemies for him. He is also generally polite to Naruto Uzumaki, upon whom Kabuto possesses a peculiar fixation on, despite the fact that they have conflicting motives during their encounters. Despite his unclear goals, Kabuto seemed to be content in following Orochimaru, using the alignment to make requests for specific bodies with which to further his knowledge.

Kabuto shows a clear view of respect to those he sees with great status, as he told Tsunade that he had the utmost respect for her as a fellow medical ninja. He sees the Sannin as great and powerful ninja, and even takes much excitement in testing his mettle against them. Due to this trait, he sees others who have not gained a high and famous reputation as nothing but inferior fighters with no skill in combat and ability.

Kabuto stated that he dislikes forcing people to do things against their will, and instead he would manipulate them by acting sympathetic to them. He plotted to send an ill Kimimaro to retrieve Sasuke, but merely spoke about how much Orochimaru is suffering, in order to stimulate Kimimaro's loyalty to move against his ill body. Orochimaru noted that Kabuto has a nasty personality. Kabuto also claimed that he is an introvert, and prefers secluded places. Due to this, he considers the Impure World Resurrection technique will bring him unwanted infamy and attention, which he notes to be the so-called perfect technique's downside.

Since merging the remains of Orochimaru into his body, Kabuto has shown to have the ambition to surpass Orochimaru. He has also recently shown interest in furthering his knowledge of techniques, the goal of his former master and as such, apparently wants to acquire Sasuke for this. He also showed interest in experimenting on Yamato and Zetsu. One of his goals seems to be able to learn the secrets of the Sage of Six Paths. Whether or not this personality change is brought on by Orochimaru's remains or not remains to be seen.

Also, while pledging an allegiance with Tobi and Akatsuki, as well as offering to resurrect an army of powerful men, Kabuto had previously provided Naruto a book containing all the information on Akatsuki, as well as leaving a trail of corpses to allow Anko Mitarashi and her brigade to follow into Mountains' Graveyard. This was apparently to lure Anko into a trap so he could capture her in order to extract her chakra, and he refused to kill her on Tobi's orders. Tobi also suspects that Kabuto plans to use the war to weaken both the Allied Forces and his own fighting power after learning that Kabuto had led the Konoha ninja to his hideout.

Kabuto, despite his rather cool personality at the beginning of the series, has been shown to be inwardly conflicted with major insecurities. According to himself, until Orochimaru was killed he was rather unsure of his identity. He stated himself that he would now do what he wanted to do as he felt no loyalty to even the people or village that raised him, detesting the fact that he had been brought up by the enemy of his people. He claimed to not know who he really was or what he wanted to do until thinking about how Naruto achieved his resolve.

Appearance
Kabuto has black eyes with grey hair kept in a ponytail and wears circular glasses. He wore a dark purple shirt with a white undershirt and a white obi around his waist worn at an angle, dark purple pants, blue sandals, and a shuriken holster on his right leg. He previously wore an Otogakure forehead protector, which instead bore the symbol of Konohagakure during his earliest appearances, and dark purple gloves with open fingers in Part I.

Shortly after Sasuke had counter-absorbed Orochimaru, Kabuto took cells and tissue from Orochimaru's true form's remains and injected himself with it. The cells and tissue slowly began to take over his body, but he resisted. After some time he attained control over Orochimaru's genetic material, his appearance changed drastically though. He looks much more like his former master, having the same markings around his eyes. He has slitted pupils reminiscent of Orochimaru and his hair is also now shoulder-length instead of kept in a ponytail. He still wears his glasses, but now has scales on his face and arms, and, presumably, the rest of his body. Kabuto wears a wine-colored cloak with two bright red, white and yellow markings similar to eyes on the hood. He has also grown a snake-like "tail" which is actually attached to his abdomen. The snake is wrapped around his waist and is usually seen coming out of the back of the cloak. His body's drastic changes, which include a bipedal serpentine body, similar to that of a nāga, with added legs, were mostly concealed by his cloak. However, this form seems to be merely a shell: he can shed this body to reveal his true form as a snake with arms, similar to Orochimaru's true form.

Abilities
Despite officially being a genin, Kabuto has proven himself to be a skilled and cunning ninja far beyond that level, particularly because of his medical abilities. His skills are said to rival those of Kakashi Hatake on more than one occasion. He has been shown to be able to kill ANBU members with relative ease and even mockingly stated he could handle at least ten ANBU members. Through keen observation, Kabuto can quickly determine the situation at hand. Even when up against a stronger opponent, he can take advantage by quickly exploiting their weakness. Kabuto is also very adaptable, as when Tsunade flipped his nervous system signals, he managed to regain control of his body quickly, a feat that impressed Tsunade.

Kabuto's chakra reserves have increased tremendously after he integrated and controlled Orochimaru's remains. A testament to this is his ability to summon and control dozens of resurrected ninja at one time for up to two days, and summon Manda II, a snake even larger than Manda. After having captured Anko, he becomes even more powerful just by absorbing Orochimaru's residual chakra that resides in her. Kabuto has also displayed some skill with barrier ninjutsu having erected one around his proximity during the Fourth Shinobi World War in order to hide his location.

He is capable of using Earth Release to move underground. Though he has made little use of it since his introduction, Kabuto is also a skilled genjutsu user, having once put almost an entire stadium to sleep during the Chūnin Exams. In the anime, he also showed the ability to make himself invisible.

Taijutsu
While he states to having lesser skill in taijutsu, Kabuto has shown proficient enough to hold his own against Tsunade, a skilled taijutsu fighter known for her devastating strikes, after tiring her out. His main style of taijutsu is to use the chakra scalpel, which allows him to form his chakra into a blade and hit his target's muscles, pressure points, and other key points of their body. During his battle with Tsunade, she remarks that Kabuto's senses and sharpness may have surpassed hers in her prime. First, he will quickly assess his opponent's strength and battle style to comprehend their movements, thereby allowing him to easily predict and dodge their attacks. He then uses his medical ninjutsu to systematically take down his opponent in order to disable and subdue them.

Medical Ninjutsu
Despite his age, Kabuto has demonstrated tremendous skill and ingenuity in medical ninjutsu. With his extensive knowledge of medical ninjutsu and of the human body, Kabuto can quickly adjust to any damage done to his body and severely injure a person with a single chakra-infused strike to the chest. He has also developed the unique ability to be able to reactivate dead cells and grow new ones; the usage of this technique effectively during battle requires him to read his opponent's moves accurately in order to prepare the area of which he would apply the cell reconstruction, a feat that he is very capable of. Through his experiments on Karin's healing abilities and powerful life-force, Kabuto was able to attain tremendous healing abilities.

He also often uses scalpels as throwing weapons instead of kunai. In Part II, Kabuto has apparently advanced his medical ninjutsu even further. He is capable of using the chakra scalpel without any hand seals, and still powerful enough to cut through wood and flesh with ease, and can use the Mystical Palm Technique at a distance.

Kabuto's medical ninjutsu has also led him to develop a series of drugs which he uses with great effect. For Sasuke, he gave drugs which aided in his training process. As shown with Manda II, he is also capable of genetically altering organisms making them bigger, stronger than the original. Kabuto has also invented a special drug that is capable of suppressing the power of a Wood Release user and a truth serum that allows him to interrogate enemies with ease.

Kabuto has demonstrated a unique affinity for corpses, and has demonstrated an interest in being able to reanimate them. This is primarily convenient when he is experimenting with test subjects, though they have been used briefly in escape situations, and may be used in combat. Kabuto's expertise in medical ninjutsu is far-reaching enough for him to be able to create an almost perfect copy of a person from a corpse in very little time and under high pressure, and keeps a sealing scroll to summon corpses for usage; he mentioned to Orochimaru that he would like to keep his stock refilled after using one. Kabuto can even use the small remains of a corpse to create an enhanced clone as he did with Manda by using the dead snake's cells and various drugs.

Summoning: Impure World Resurrection
As a further testament to his corpse theme, Kabuto can perform the Summoning: Impure World Resurrection technique — which only Orochimaru and Tobirama Senju could before. Kabuto states that his usage of the technique surpasses that of the two other users, and he supports that by resurrecting five deceased Akatsuki members at once. He also states that he can resurrect many other powerful ninja under his control, including Madara Uchiha. He applied a seal on the corpses that doesn't completely rob them of their free will, but still controls their body movement against their will — a seal different from the one Orochimaru used. Kabuto showed his great prowess in this particular technique by summoning a large group of famous and powerful shinobi, including deceased jinchūriki, Kage, and many others. He is even able to remotely monitor the bodies as well as re-write the commands given to the resurrected people, allowing him to rob them of their free will whenever he wants.

Snake Techniques
After implanting Orochimaru's cells into his body, Kabuto gained all of his snake-oriented techniques and abilities, first exhibiting some of these skills to kill several Takigakure ninja with great ease using multiple snakes. Kabuto is able to communicate telepathically with his snakes using the one that serves as his tail. He can also use the Hidden Shadow Snake Hands for a quick ambush attack. Moreover, with his new form, Kabuto is capable of injecting drugs that he has developed, directly through the fangs of the snakes that he creates from his body. He is also seemingly able to alter the size of these particular snakes at will, even after summoning them.

Another ability orientated with this snake-theme is that Kabuto can shed his skin and turn into a white snake with arms, similar to Orochimaru's true form. While in this form, he can move at very fast speeds and even swallow a fully grown man whole.

To counteract genjutsu that are dependent upon direct eye contact, Kabuto can instead rely solely upon his snakes' ability to perceive their surroundings through sensing the ambient temperatures and smells using their tongues, rather than his own sight. After researching the Hōzuki clan's Hydrification Technique, through Suigetsu, he altered it in order to instead of leaving his bodily fluids behind, in a manner similar to how a snake sheds its skin.

Senjutsu
After Orochimaru's death, Kabuto travelled across the world and ultimately discovered the location of the Ryūchi Cave. Here, he was taught senjutsu by the White Snake Sage and together with the research done to Jūgo's clan's abilities, gained access to a Sage Mode which, according to him, meant that he was a snake no longer, but had instead transcended into a dragon.

Physically, Kabuto undergoes little alteration in this form, with the only visible changes being the markings around his eyes extending onto his back and the growth of four horn-like protrusions on the back of his head which he later stated to not be horns, as well as darkened sclera. While the pros and cons of this version of senjutsu have yet to be fully explored, it appears to greatly enhance Kabuto's perception and reflexes, to such an extent that he can even dodge the arrows fired by Sasuke's Susanoo, which are noted for their tremendous speed.

Intelligence
As a former agent for Akatsuki, as well as being the right-hand man and spy for Orochimaru, Kabuto has gained access to large stores of knowledge which he uses for devastating effect. This includes him finding Tobi, knowing about Zetsu, outwitting Kurotsuchi by knowing her abilities, etc.

Like his mentor Orochimaru, Kabuto has shown himself as an extensive researcher, performing multiple experiments to increase or neutralise an individual's abilities, as shown by his creation of Manda II, his intricate knowledge of the Wood Release, his mastery of the Summoning: Impure World Resurrection, the empowering of the Zetsu army, his enhancement of Madara's "golden age" body and the enhancements done to his own body by studying and reverse engineering the abilities of team Taka.

He has also shown himself to be a very skilled manipulator. For years, he was able to convince all of Konohagakure into believing he was a genuinely kind-hearted man with inept shinobi skill outside of medical skills (to which he made it appear he was only decent at) to make it easier in gathering information. He made Orochimaru doubt his true loyalties on at least one occasion, but since Orochimaru's demise, he has expressed his true support of his former master's ideology. He has shown to be able to use his strong powers of deception to fool his targets into aiding him in several manners, even including a master manipulator such as Tobi, well known for his own ability to manipulate others. He also used such manipulative methods with the Summoning: Impure World Resurrection, by allowing the revived to retain their personalities, so they can be used for psychological warfare, as well as memories, emotions, and creativity to enhance combat efficiency. This shows that Kabuto understands the human mind very well, and takes advantage of that to help meet his own ends.

However, Kabuto's present loyalties still remain unclear due to his many conflicting comments and actions.

Chūnin Exam Arc
Prior to the first phase of the Chūnin Exams, Kabuto befriends the members of the Rookie Nine with information on their fellow competitors. During the second phase of the exam, Kabuto joins forces with Team 7 in an attempt to finish the phase with little hassle. When the group encounters Team Oboro, Kabuto's glasses are knocked off of his face after saving Naruto from an attack. This causes Kabuto to momentarily lose his cool and reveal his Killing Intent, paralysing both Team Oboro and Sasuke and Sakura. This gives Naruto Uzumaki the opportunity to defeat the Ame genin. Upon completing the second test, Kabuto reunited with his team-mates, Yoroi Akadō and Misumi Tsurugi. Back with his team, Kabuto reports to Orochimaru what he has learned about Sasuke Uchiha.

With Orochimaru now in a position to observe Sasuke firsthand, Kabuto forfeits prior to the preliminary matches of the Chūnin Exam. While explaining to Naruto that he is fatigued, injured, and unwilling to risk his life further, Kabuto actually forfeits because he is afraid that prolonged fighting will cause him to show his true abilities, blowing his cover. After Orochimaru gathers enough of his own intelligence about Sasuke, he instructs Kabuto to kidnap Sasuke. He was able to take out the eight ANBU members guarding Sasuke and almost succeeded in accomplishing this task, but Kakashi Hatake intervenes before he could finish, forcing Kabuto to flee.

Later, he speaks with Baki and they discuss the upcoming Suna and Oto's invasion of Konoha.

Invasion of Konoha Arc
During the final matches of the Chūnin Exam, Kabuto kills and disguises himself as an ANBU member, and mingles with the audience. During Naruto and Neji Hyūga's battle, he heals Hinata.

When Sasuke injures Gaara, Kabuto uses a genjutsu to put the audience to sleep and signal the start of the invasion of Konoha. During the invasion, Kabuto has Oto ninja go after Naruto when he starts to pursue Sasuke, fearing what he will eventually become if he is not dealt with soon. However, it appears he already knew it would fail as he wanted to test Naruto.

He does not contribute in the battle, pointing out that Kakashi would only copy his abilities, and flees from the village when the invasion fails.

Search for Tsunade Arc
With Orochimaru being heavily injured as a result of the failed invasion, Kabuto accompanies him in searching for Tsunade, who they hope will be able to heal him. Upon finding and in time seeming to persuade Tsunade, Kabuto notices that Tsunade's medical techniques is filled with killing intent, and as such stops her before she can kill Orochimaru. With it clear that Tsunade won't willingly help them, Kabuto fights Tsunade in the hopes that he can force her into submission. After taking a Military Rations Pill to boost his abilities, Kabuto is able to keep up with Tsunade and land a number of disabling attacks, though she eventually lands a crippling attack upon him. Despite his efforts he realises that he is completely outmatched by the Sannin, Tsunade, even in her fallen state. Upon recovering, Kabuto uses a kunai to cut his hand, drenching Tsunade in his blood and invoking her haemophobia, allowing him to land a series of unopposed attacks.

When reinforcements for Tsunade arrive, Kabuto is pitted against Shizune, whom he quickly defeats. As he returns his attention to Tsunade, Naruto also comes to her rescue, surprised that Kabuto is a spy for Orochimaru. While Kabuto doesn't view Naruto as much of a threat, Naruto is able to hit Kabuto with his Rasengan, doing so much damage to Kabuto that he is unable to fully heal. While Kabuto had managed to strike a fatal blow to Naruto's heart before the Rasengan hit him, Tsunade heals Naruto before he can die, leaving Kabuto to lie on the ground, defeated. He later recovers to the point of helping Orochimaru summon Manda, and flees with his master once Orochimaru is defeated.

Sasuke Retrieval Arc
As Orochimaru anxiously awaits Sasuke's arrival at their lair, Kabuto encourages him to switch to a new body while he still can, even offering his own body. Although Orochimaru rejects the offer, Kabuto finds a strong body for Orochimaru to switch to just in case. Although his efforts seem to have been needless for a while, Orochimaru finally grows tired of waiting for Sasuke and switches to the body that Kabuto prepared. He also manipulated Kimimaro to leave to retrieve Sasuke, despite the latter's terminal illness.

Sasuke and Sai Arc
When Team Yamato comes to meet one of Sasori's agents, Kabuto is revealed to be that agent. Yamato, disguised as Sasori, is able to learn some things from Kabuto, though just as he is about to capture the latter Orochimaru shows up. Although it seems as though Orochimaru is about to kill Kabuto as a traitor, Kabuto cuts off the Sasori disguise's head, having intended to kill the actual Sasori under Orochimaru's orders. With his cover blown, Yamato calls to the rest of his team for assistance, and Naruto eventually starts to fight Orochimaru. At the start of the battle, Kabuto tries to attack Naruto who has slipped into his three-tailed form, though he is almost instantly repelled a good distance by one of Naruto's roars, knocking out Sakura in the process. He returns back to the bridge and heals Sakura, who had been attacked by Naruto, and hints that the Akatsuki is the greater enemy.

After the battle, Kabuto joins Orochimaru and Team Yamato member Sai in returning to their hideout, and Kabuto is tasked with leaving behind a dead body that looks like Sai to prevent anyone from following them. When Sai is later captured, Kabuto comes to his aid, only to be captured by Sai instead. Unable to escape, Kabuto is forthcoming with information, and discourages Naruto from trying to retrieve the traitorous Sasuke. Kabuto is left by himself as Team 7 searches the lair, though is at some point freed and joins Orochimaru and Sasuke when they depart.

Three-Tails Arc
Realizing that the time was fast approaching for him to change bodies, Orochimaru sent Kabuto to fetch Guren. When Kabuto nears her location Guren attacks him to see if he is worthy of being Orochimaru's attendant. Satisfied, she accompanies him to Orochimaru's lair and is left in charge of testing the prisoners there and forming a team.

When Guren and her team fail to kill a group of Konoha ninja, Kabuto has them help in summoning the Three-Tailed Beast. Kabuto ordered Guren to restrain it with her Crystal Release. When she proves unable to do so, Kabuto retreats upon realizing he needs to rethink their strategy.

Later, he begins preparations for a final attempt to capture the Three-Tails during which he secretly meets with Rinji, who is revealed to be a spy for Kabuto. After learning that Konoha has begun attempting to seal away the Three-Tails, Kabuto retrieves Guren and Yūkimaru to stop them.

While successfully stopping the Konoha shinobi from sealing the Three-Tails, they manage to obtain Yūkimaru, much to Kabuto's dismay. Deciding to take desperate measures, Kabuto tricked Kigiri, Kihō, and Nurari into thinking they were dying from the injuries they sustained from the Konoha-nin and convinced them to go through a gruelling operation of having cursed seals forcibly activated.

He then disguises himself as Rinji, tricks Yūkimaru to use his power to unleash the Three-Tail's full might despite knowing how weakened Yūkimaru was. After a failed attempt to have Yūkimaru make the Three-Tails go on a rampage, Kabuto, disguised as Rinji, reveals to Yūkimaru that it was Guren who killed his mother, but is shocked that Yūkimaru forgives her. He then attacks Guren and Yūkimaru with scalpels, but are deflected by Naruto. Naruto throws one of the scalpels cuts Rinji's face which turns out to be a mask and it falls off, revealing that he is Kabuto.

Since his meeting with Rinji, Kabuto has been posing as him. Kabuto and Naruto fight it out, with Naruto having improved enough to seemingly gain the upper hand over Kabuto. As Guren tries to escape with Yūkimaru, Kabuto then summons Rinji with his Dead Soul Technique to stop her. Guren fights him, only to be immobilized by his bats. Guren who made her promise to protect Yūkimaru at the cost of her life grabs Rinji from behind and sacrifice herself to kill him. Yūkimaru then screams in agony at what appears to be the loss of Guren. The screaming once again awakens Yūkimaru powers and causes the Three-Tails to breaks out of the seal and go on a rampage. Kabuto then leaves the scenery satisfied with what was happening.

Itachi Pursuit Arc
After Orochimaru's defeat at the hands of Sasuke, Kabuto integrates remains from Orochimaru's body into his own. The remains start taking control of his body, and Kabuto is in a constant struggle to keep them from spreading. When he later confronts Naruto, Kabuto explains his reasons: he has always defined himself as someone's underling, never living for himself. By taking the remains of Orochimaru he can become strong enough that he need never serve anyone ever again. This being an emulation of Naruto's struggles with the Nine-Tailed Demon Fox, Kabuto gives him a book containing Orochimaru's information on Akatsuki in thanks. He departs before he can be apprehended, noting that he will someday fight Naruto after he avenges Orochimaru by killing Sasuke.

Konoha History Arc
After Naruto Uzumaki defeats Sabiru, Kabuto, hidden in some trees, kills him by throwing a presumably poisoned senbon to the back of his neck, so no information regarding who he works for would be leaked.

Confining the Jinchūriki Arc
Kabuto kills three Takigakure shinobi to test his control over his new powers. Satisfied, he heads to the Mountains' Graveyard, leaving a trail of bodies that the Anko-led Infiltration and Reconnaissance Party uses to follow him.

Once there he confronts Tobi, who is operating as "Madara Uchiha". Remembering that Kabuto was once Akatsuki's spy, Tobi tries to kill him for his traitorous actions. Kabuto responds by using the Summoning: Impure World Resurrection to revive five deceased members of Akatsuki, an incentive for Tobi to accept his help in the approaching Fourth Shinobi World War. In return, Kabuto asks that he be given Sasuke to learn the truth about ninjutsu.

Tobi asks what would happen if he doesn't accept, to which Kabuto responds by summoning a sixth coffin. Greatly disturbed by the coffin's contents, Tobi was forced to agree, though insists upon the condition that he not turn over Sasuke until after the war. The two head off to reformulate their war plans. In the anime, as Tobi was about to leave Mountains' Graveyard, Kabuto stops him and asks where he was going. Tobi replies that it was none of his concern, but tells him that he was going to Amegakure, to which Kabuto gives a devious smile after their brief conversation.

When Tobi receives intel on the location of the Eight-Tails and Nine-Tails, Kabuto offers to go capture them. Kabuto explains that he is interested in studying Yamato, the Nine-Tails' guardian. If Tobi would he prefer he not go, Kabuto says he would settle for a chance to study Zetsu. Tobi replies that he can have his own Zetsu to study if he manages to catch the Nine-Tails. Kabuto revives Deidara and together they fly to the Island Turtle upon one of Deidara's clay birds. As they get closer to the island Deidara creates clay clones of themselves, which the intercepting Third Tsuchikage attacks. The time this buys is short-lived, as the Tsuchikage himself was a rock clone; the Tsuchikage and his escorts confront the real Kabuto and Deidara.

While Deidara and the Tsuchikage exchange insults, Manda II seeks out and slows down the Island Turtle. To keep it from moving, Kabuto has Deidara hit it with an explosive squid. Kabuto goes ashore, leaving distracting the Tsuchikage to Deidara. Kurotsuchi pursues Kabuto and manages to catch him. Yamato then appears, creating a route for Aoba Yamashiro to get close to Kabuto and read his mind. Before Aoba is able to begin doing so, Kabuto sheds his captured body and kidnaps Yamato. He retreats into Manda II's nose and returns to Tobi, de-summoning Deidara in the process. When Tobi questions his failure, Kabuto explains that studying Yamato will allow him to make the White Zetsu Army stronger. Tobi accepts this explanation and tells Kabuto to get to work.

Shinobi World War Arc
Proposing to keep the drugged Yamato alive, so he may strengthen the White Zetsu Army further, Kabuto states that use of the Human Path wouldn't be necessary to extract information, as a combination of his truth serum and Tobi's Sharingan would suffice. With their forces amassed and modifications completed, Kabuto mobilises his revived shinobi to the main battlefields, with the exception of those he forms into a Surprise Attack and Diversion Platoon. After instructing the latter, Kabuto himself departs, capturing the surveying Anko after a brief battle. When Tobi later demands her death, Kabuto refuses on the grounds that the traces of Orochimaru's chakra in her could help improve his control over the resurrected shinobi, which was in their best interests.

Complying with Tobi's request to gain his approval, Kabuto demonstrates his technique using Fū as a sacrifice to resurrect Torune, accompanying it with a step-by-step explanation. Claiming that it had no weaknesses, he reveals the few methods able to halt the technique, before leaving the apparently satisfied Tobi. However, Kabuto is unconcerned by his recent admissions, due to the possession of another technique and the prospect of soon learning the secrets of the Sage of Six Paths. A now isolated Kabuto then starts to drain Anko's chakra, acquiring an incredible increase in power, just as a number of the revived shinobi encounter the Third Division.

Erasing their consciousness soon after they make contact with the division, he commands the assault to begin. After seeing how retaining their emotions could cause the revived shinobi's defeat, Kabuto remotely subdues as many as he can, leaving only those whose individualities may present an advantage intact. Directly interfering as the need arises, he later has Gari and Pakura summon the previous generation of the Seven Ninja Swordsmen of the Mist, to retain Akatsuki's superiority. However, despite having Haku intercept Kakashi and much to his shock, Zabuza Momochi and his crucial technique are ultimately defeated.

Elsewhere with Mū's discovery on approach to the Fourth Division, Kabuto has him summon the Fourth Kazekage, Second Mizukage and Third Raikage, just as more of his forces engage the First Division. He then leaves them to their own devices, believing that taking their identities could hinder their fighting capabilities. This backfires in the case of Hanzō, who contradicts Kabuto's control before he can intervene, handing victory to the opposing Fifth Division.

When Tobi goes out of the way to acquire the sealed Gold and Silver Brothers from the Allied Forces, Kabuto deduces that Tobi wants the Nine-Tails chakra within them. However, Kabuto instantly realises that Tobi only has one of the Eight-Tails' tails so he couldn't understand what Tobi was planning.

Later, during the second day of the War, he reacted in shock when Naruto Uzumaki in his Nine-Tails Chakra Mode defeated Toroi near instantly with a Rasengan. Pleased at the prospect of finding Naruto and Killer B before Tobi, he thought happily of how he would be able to manipulate Tobi in exchange for them and wished that he could see the look on his face, but lamented that his mask hid it. As such, he has Itachi and Nagato, who up until now had been talking to Naruto and B, attack them immediately in the hopes of turning the tides of the battle in his favour.

When Itachi attempts to attack Naruto with his Mangekyō Sharingan, the crow Itachi had implanted within Naruto comes out, and stops Itachi, who then begins attacking Nagato and his summons, much to Kabuto's surprise. When Kabuto learns the crow had Shisui's eye, he gets excited about the prospect of collecting it, and removes Nagato's consciousness, completely taking control of him. As Kabuto watches on he decides to kill the jinchūriki temporarily and store their souls in the King of Hell and then revive them later, just as long as he got his hands on them before Tobi did. He later remembers that he should capture Itachi who had escaped his control as well. After Nagato is sealed, a visibly angered Kabuto laments Nagato's lack of mobility due to his injured legs, and comments that he was unable to see the last attack due to Itachi blinding the Giant Snake-Tailed Chameleon and King of Hell with kunai. He then resigns himself to unleashing his "prized possession" and grins menacingly, letting his serpentine tongue stick out in true Orochimaru fashion.

As part of the Fourth Division faces the Third Raikage, Kabuto reveals that he simply used him in order to buy enough time to accomplish the summon of "that guy", before then deciding to eradicate the Raikage's personality. Once again setting his sights on the acquisition of Naruto, he resorts to activating the Raikage's "strongest spear" after prior attempts at incapacitating him result in nothing but failure, in spite of being aware of the considerable risk of injury it poses towards his target. Afterwards, Kabuto is relieved that "Mū" was sealed before he could reveal his means of escape to Ōnoki. However, due to his splitting, he says it will take a bit longer to summon "that". After some time passed, Mū used the Summoning Technique to get Kabuto's trump card into play, which is later revealed to be Madara Uchiha, whose name Tobi has been using as his own.

After devastating the battlefield, Kabuto marvels at the power of someone near that of the Sage of the Six Paths. When Madara asks him again how much he knew about him, Kabuto tells him that he realised that Madara didn't die during the battle with Hashirama at the Valley of the End. He then tells him that he did not know the details of his and Tobi's plans but he somehow doubted that Tobi would act as planned. He then informs Madara who tried to summon the Nine-Tails that it resided within a host. Visibly pleased with himself, Kabuto thinks that if he could effectively manipulate Madara, he could control the battlefield.

As Kabuto, still in control of Mū has him attack the remainder of the Fourth Division alongside Madara, Mū is buffeted by A's attack. As Mū emerges from the rubble, to see Madara engaging the five Kage, he is pursued by Dodai and the Hokage Guard Platoon. As Mei envelops the battlefield in mist, Kabuto positions Mū directly in front of Madara. Thinking that if Ōnoki was in fact making A lighter, then his attacks would not have any weight behind them. Despite this theory, Mū is knocked away by A much to his shock.

As the battle between the Kage and Madara continue, Kabuto while having Mū evade the Hokage Guard Platoon and Dodai thinks to himself that there weren't shinobi in the world as powerful as Hashirama, whose power was once thought to be a mere myth — just as the Sage of the Six Paths was. He later muses to himself as Hashirama's face is revealed to be jutting out of Madara's now-exposed chest that the combination of two of the most powerful shinobi in the world was his trump card.

With his location uncovered by Itachi, who tells him that he could sense the source where he was being controlled came from, Kabuto congratulates him for going as far as to breach the barrier he had placed around his location. Kabuto then tells Itachi to remember that killing him still would not end the technique and that only he could end it. After his tail sees Sasuke behind Itachi, Kabuto breaks out into maniacal laughter, stating that his luck had finally changed, to a visibly exasperated Itachi.

Excited that his reward for his part in the war had been brought to him, he tells Itachi that he'd love to explain the ins and outs of the Summoning: Impure World Resurrection technique, but he doesn't think Sasuke would stay quiet for that long. He then tries to use Sasuke's hatred to help him defeat Itachi. However, Sasuke who has now learned the truth about Itachi chooses to side with his brother over Kabuto. With this, Kabuto prepares for battle stating that it'd be an interesting event.

Closing his hood and stating that he was an introverted person and as such it was unsettling to be stared at by so many people, Kabuto sends his snakes charging into Sasuke and Itachi. The brothers are able to fend this attack off, however, Kabuto uses this opportunity to hide in one of his snakes. Here, Kabuto reveals the unique abilities that he had gained from experimenting with Sasuke's former team-mates: Karin's healing abilities, a similar ability to Suigetsu's Hydrification Technique and Jūgo's ability to absorb natural energy. After revealing that he had found and trained at the Ryūchi Cave — much to Itachi's shock — he narrowly dodges Sasuke's attack stating that his perception skills had been greatly enhanced as well. Emerging from the snake's mouth he reveals that he had finally surpassed Orochimaru and was able to become a sage and declares that he was now a dragon after Sasuke calls him an imperfect snake like Orochimaru.

As Kabuto attacks the brothers with the Sage Art: White Rage Technique, he lowers the brille of his eyes which effectively block out the harsh light of the technique. Also noting that he had liquefied his body and as such was able to absorb the paralysing vibrations of the technique as well, he moves through the blinding light at first intending to target Itachi and rewrite his tag. At the last minute however, he changes his mind and opening his mouth wide — attacks Sasuke, seemingly intent on swallowing him. After Itachi interferes however, Kabuto asks him if he was able to sense him. After Itachi denies this, stating it was Nagato and not him, Kabuto begins to chastise Itachi calling him a liar and then states that such a makeshift duo could never defeat him.

Looking on curiously from the ceiling of the cave,as the brothers formulate a new strategy, Kabuto guards himself against Itachi's Yasaka Magatama attack and narrowly avoids Sasuke's arrow once again. His snake-tails is caught by the arrow and Kabuto seemingly moves to use Sasuke's sword to sever it. Itachi however intercepts the attack, but Kabuto reveals that this was his intention though Kabuto is shocked when Itachi disperses into a flock of crows and then once again avoids an attack from Itachi. Part of his horn is severed however, and Kabuto states that it would take some getting used to the fact that he had horns now.

Naruto Shippūden 2: Bonds
Kabuto makes a small appearance along with Orochimaru. He tells Sasuke how Konoha had been attacked by the Land of the Sky, at which Sasuke told him he doesn't care. Orochimaru then ordered him to get a scroll and capture Shinnō. In the end, Sasuke failed to bring Shinnō, at which Kabuto was shocked.

Kabuto 'becoming' a dragon instead of a snake simply means he upgraded, not that he changed species.

What am I anyway… The pain of not having an identity… I'd think you should understand… Naruto."
