Kiba Inuzuka

is a major supporting characters of the series. He is a chūnin-level shinobi of Konohagakure's Inuzuka clan. He, along with his partner Akamaru, are both members of Team Kurenai.

Background
At a very young age, Akamaru was given to Kiba by his mother, Tsume, and the two became very close soon afterwards. Before entering the Academy, Kiba and Akamaru played together a great deal, resulting in Tsume getting angry because they weren't training enough. During Kiba's time at the Academy, he often cut class with Akamaru, stating that he wasn't suited to sit still at a desk, or otherwise getting into trouble, along with Chōji Akimichi, Shikamaru Nara, and Naruto Uzumaki. Together, these four would skip class and go to the practice hall (not to practice). They thought that it was fun to also test the patience of Iruka Umino, their Academy instructor.

At some time in the past, Kiba knew his father; but because of his mother's attitude, Tsume scared him away, leaving him just with her and his sister Hana Inuzuka. Despite this, Kiba stays in a close relationship with his sister and mother, although he seems to agree that Tsume is rather frightening.

Personality
Kiba is often short-tempered and impulsive (in stark contrast to his team-mates Shino and Hinata), and can be prone to making mistakes when he becomes agitated in battle. He also enjoys combat even when facing particularly strong opponents. He cares deeply for Akamaru, and is willing to do whatever is necessary to protect him. And, despite his rather gruff attitude, many of Kiba's actions reveal that he is very close to his older sister, Hana, and remains fiercely loyal to his clan and has great pride in it.

Kiba often argues with Shino over what course of action the group should take, particularly when Shino advises caution. Kiba often sees himself as the group leader, and becomes offended at any of Shino's actions that he perceives as challenging his leadership. It seems that there was a contest for leadership of Team 8 during the Chūnin Exams, as Kiba said Hinata voted for him. Despite his disagreements with Shino, he considers Shino a friend, and respects his fighting capabilities. Kiba has became very close to Hinata and acts brotherly toward her, but tends to worry about her, urging her to be strong before the second phase of the exam, and to forfeit rather than face a dangerous opponent. Kiba likes to playfully tease Hinata about her affections for Naruto Uzumaki. This usually includes telling her that Naruto is nearby, or just mentioning her reactions to him to other people, much to her embarrassment. Despite this, they have a strong friendship.

In the anime, mostly in the filler arcs, Kiba is shown to also get along well with Naruto, despite their arguments. This seems to be proven when it was shown that Kiba, Akamaru, Naruto, Chōji, and Shikamaru skipped classes together and play in the park. Those three seem to be some of the first true friends he made in the village. They also have somewhat of a rivalry that stems from childhood. He was shown to have become frustrated with Naruto's growth and is determined to surpass him. He even showed admiration towards Naruto, stating that he wanted to become like him.

Kiba also dreams of becoming the Hokage someday and expressed this desire both during his fight with Naruto during the Chūnin Exams as well as during the Fourth Shinobi World War, where he deduced that if he fought and gained a name for himself during the war, it would be a step in the direction of becoming the Hokage, an ideal he mentions again later on.

Appearance
Kiba's personality and fighting style is further complemented by his wild appearance as while clearly human, he has several physical traits more akin to animals. Like most of his clan, he has messy brown hair, sharp black eyes with vertical slit-like pupils, pronounced canine teeth, and nails that he can change into claws. He also has the distinctive red fang markings of the Inuzuka clan on his cheeks.

During Part I, Kiba's attire consisted of dark greyish pants reaching to his calves and a grey, hooded fur-lined coat, with the hood usually placed on his head, over an apparent plate of armour and fishnet undershirt seen in his fight with Sakon and Ukon, with a blue forehead protector and blue sandals.

During Part II, each piece of his outfit, including his forehead protector, switched to a black colour, with his coat being replaced by what looks like a nowadays leather form fitting black jacket, with zips over the chest and sleeves, along with black pants and sandals, also zipped, matching the jacket. He, along with the rest of the Konoha 11, dons the standard Konohagakure shinobi outfit during the Fourth Shinobi World War.

Abilities
Kiba's fighting style, like all Inuzuka, revolve around collaboration techniques along with his companion Akamaru; but he's also able to make a perfect synchronisation with his team-mates as seen during his fight against Tobi where he works perfectly with Naruto. Due to his senses, as well as teaming up with Akamaru, he was the only genin to notice ANBU stationed in the Chūnin Exams arena. He also likes to use some ninja weapons such as military pills to increase his chakra and that of Akamaru's; smoke bombs to blind his enemy and make a precise attack or set a trap such as a fake Akamaru that explodes throwing dozens of kunai as seen during his fight against Ukon.

Taijutsu
Because of his practised fighting style and the use of his clan's Four Legs Technique, Kiba has a quick reaction time, honed reflexes, increased physical strength, and is also very fast. Using this fighting-style, he practises his clan's famed "hit-and-run" tactics where he delivers powerful attacks to the opponent, moving at speeds that they can hardly keep up with. This was most prominently seen during his battle with Naruto in Part I, the latter noted that it was very hard to land an attack on Kiba because he could barely keep up with him. In Part II, during his fight against Tobi, not only was Kiba the only one able to discover where Tobi had teleported to, he was even fast enough to surprise Tobi and attack him from behind, without anyone noticing the attack.

Ninjutsu
Kiba's mostly relies on the use of his clan's ninjutsu during battle. He has also, however, shown skill with the use of the Shadow Clone Technique, which he learned in order to use his clan's more powerful techniques. Kiba is also proficient with the Transformation Technique; first displaying this by using the technique to change his canine partner Akamaru into a full-body clone of himself (Beast Human Clone), and through use of the more advanced Combination Transformation technique, merge himself with Akamaru (and optionally, a shadow clone) to become a giant multi-headed dog capable of more powerful attacks.

Inuzuka Clan Abilities
He is proficient in several canine-based techniques. His battle style is usually a combination of taijutsu enhanced by his special clan techniques. He fights and attacks with the ferocity of a beast, utilising his sharp claws and other beast-like abilities that he gains from his Four Legs Technique. Despite his pride as an individual fighter, he usually performs tag-team tactics with Akamaru. Together, they can attack at high speed with excellent coordination, as Kiba can turn Akamaru into an identical clone of himself. In dire circumstances, they are able to transform together and use the Human Beast Combination Transformation: Double-Headed Wolf, and then attack by using the Fang Wolf Fang, which is almost impossible to avoid, let alone block. In the anime, during the Fourth Shinobi World War, he developed a stronger version of the technique called the Super Fang Wolf Fang which could pierce through three Rashōmon gates without losing its power. Later, during the face-off against the Ten-Tails, Kiba is shown to have learned the Shadow Clone Technique. By combining himself, his clone, and Akamaru, they can use the Human Beast Mixture Transformation: Three-Headed Wolf and attack using the Tail Chasing Fang Fang Rotating Fang.

According to the third Naruto databook, Kiba learned how to use the between Part I and Part II. Other than giving him the power to protect someone he cares about, it is unknown what it does or even if it is a weapon or a technique.

Enhanced Senses
As a member of the Inuzuka clan, Kiba possesses enhanced canine-related human skills such as his sense of smell. His most powerful sense, and weapon, is his sense of smell. By concentrating his chakra in his nose, Kiba can make his sense of smell a thousand times more sensitive than average; making it easy for him to distinguish people by their scent, as seen during his fight against Naruto. In Part II, Kiba stated that his sense of smell was stronger than that of a ninja hound — a feat that impressed Kakashi after he located Sasuke, noting that the Inuzuka clan must be proud of him. His sense of smell can clearly determine the physical condition of an individual, even from a considerable distance. Naturally, Kiba is the ideal choice to be included in all reconnaissance and tracking missions. Not only is able to actively keep track of targets, his keen senses allow him to identify traps that others would miss, whilst also being an excellent lookout by detecting any approaching enemy shinobi.

Despite his nose being a great advantage, his powerful sense of smell was like a double-edged sword, rendering him vulnerable to strong odours. For example, during his fight against Naruto in the preliminary round of the Chūnin Exams, Naruto farted in Kiba's face — a smell that was greatly enhanced due to Kiba's sensitive nose, causing Kiba to be stunned and eventually lose the fight. During his two-headed wolf transformation, his revolution speed is so fast that he cannot see anything but he is able to target his enemy with his sense of smell after Akamaru uses Dynamic Marking.

Chūnin Exam Arc
During the first phase of the Chūnin Exams, Kiba used Akamaru to spy on the other examinees' tests and tell him the answers. During the second phase of the exam, while Team 8 easily took an Earth scroll from a rival team, Kiba wished to acquire yet another to narrow the competition, despite Shino and Hinata's reservations. While investigating a confrontation between two teams, they witnessed Gaara killing three Rain Genin, with Akamaru being traumatised by the amount of power he sensed from Gaara.

Kiba was matched against Naruto in the seventh match of the preliminaries. Kiba thought that he would easily win, since Naruto had been the worst student at the academy. Naruto then became extremely annoyed at Kiba's low opinion of him. While Kiba initially had an advantage, due to his superior speed and strengthening Akamaru with a Military Rations Pill, Naruto tricked him into knocking Akamaru unconscious, then, after farting in Kiba's face (overwhelming his sense of smell and disorienting him), defeated him with the Naruto Uzumaki Combo. Kiba regained consciousness on the stretcher, and urged Hinata to forfeit if she was matched against Gaara or Neji Hyūga.

A month later, at the finals, Kiba watched the match between Naruto and Neji with Hinata. He appeared to have gained respect for Naruto at this point, as, when he heard Izumo and Kotetsu doubting Naruto's abilities to win, Kiba remembered how he had thought the same thing during his own match with Naruto, and had ended up losing. He also loudly cheered for Naruto during the match. After Kabuto healed Hinata when she began coughing up blood, he rendered Kiba unconscious (in the anime, he was about to recognise him), leaving him unable to assist the Konoha ninja during the invasion.

Invasion of Konoha Arc
Kiba can be seen at the Third Hokage's funeral alongside the other villagers, mourning his death.

Sasuke Retrieval Arc
As a request from Shikamaru, Kiba was the only member from his team to participate in the task of stopping Sasuke Uchiha from defecting from Konoha. Kiba was lined in front of the group due to the fact that he knows most of the Land of Fire's terrain and with his sense of smell, he could not only track Sasuke's scent, he could also detect the enemies' scent to avoid any traps in the way. Kiba smelled the Sound Four and proceeded to attack, but they were trapped by Jirōbō. After escaping, Neji and Chōji stayed behind fighting their corresponding opponent. Kiba and the others continued their pursuing for Sasuke, and soon they caught up with Sakon and Tayuya and engaged them in battle. After Naruto seized the container holding Sasuke, Akamaru set off a bunch of exploding tags, but one with the result of knocking Kiba along with Sakon and Ukon off a cliff. Kiba and Akamaru started fighting them, but when Sakon and Ukon pushed their cursed seal into level two, their power increased in such a huge way leaving Kiba and Akamaru with the only option to use their new technique, Human Beast Combination Transformation: Double-Headed Wolf. Despite using this technique and their Fang Wolf Fang, the brothers were able to block their attack with Summoning: Rashōmon.

With the wolf transformation dispersed, Akamaru was attacked and left heavily injured along with Sakon for the meantime. Ukon merged himself with Kiba's body thanks to his special technique. Not having any options, Kiba stabbed himself in the stomach, causing him and Ukon to start coughing up blood. Kiba found Akamaru and retreated frantically, fearing for their lives, hoping to escape the brothers. Kiba smelled three other individuals, which were later shown to belong to the Sand Siblings. Kiba and Akamaru were saved by Kankurō, who trapped and killed the brothers with his puppets. Kiba was wounded with severe, but not life-threatening, lacerations, but Akamaru had suffered much harsher damage; tendons in all four of his legs had been ripped and his sister, Hana Inuzuka, told him that they wouldn't be able to take walks for a while. After Akamaru recovered, Kiba swore to never let anything happen to him again.

Pre-Shippūden Filler Arcs
Kiba made a number of appearances in the anime's filler arcs, often being sent on missions with Hinata and Naruto.

During the Search for the Bikōchū Arc, Kiba, Hinata, Shino, and Naruto were sent on a mission to find a bikōchū beetle which could be used to track down Sasuke Uchiha. They went to the forest where the bikōchū was, but there were some ninja of the Kamizuru clan watching them who wanted the insect too. After Hinata was able to locate and capture the insect, she was taken prisoner by the Kamizuru clansmen, to be used as an exchange for the bikōchū. Kiba and the others went to rescue her, but tried to trick the Kamizuru into giving them Hinata before they gave up the bikōchū. They were tricked too, being attacked by the Kamizuru when they met and subsequently trapped in a cave. Hinata was able to rescue them, but the mission failed when Naruto farted and the smell made the beetle attracted to Naruto's behind.

He typically fought with Naruto over who should lead the team. In episode 158, the Academy students were divided into teams of three and were assigned to a genin who would lead them on a mission against the other teams. Kiba was assigned to lead a team of three Academy students: Taiga, Rai, and Yamane. His time with them was not covered much, except that he was doing better than Naruto.

During the Bounty Hunter Arc, Kiba, Hinata and Naruto were assigned the easy task of capturing a crook. In searching for information about the crook, they met Sazanami, who was pursuing the thief too. Sazanami told them that the thief, Gosunkugi, was a dangerous killer, and also a skilled ninja. Sazanami said that he didn't want any competition, and rendered them all unconscious. When he was later wounded fighting Gosunkugi, they took him to safety, in turn discovering that he was also a wanted criminal.

The bounty hunter revealed that he had been framed for murdering a family, and that the thief that he and Kiba's group were hunting was the culprit. Kiba, Naruto and Hinata located the thief in a nearby city, in the process of attempting to steal a valuable bell. Sazanami arrived, and the four began fighting with the allies of Gosunkugi, which actually was just a trap to capture them while the thief stole the bell. Sazanami captured the thief, but he was suddenly captured by another hunter, only for Sazanami to be proven innocent in the end. Despite this, Kiba's group failed the mission, because they did not capture the thief.

During the Impostor Arc, Naruto, Kiba, and Hinata were once again teamed together, this time to find a treasure chest. They were given a mission to test their teamwork, and told they would return to the Academy if they failed this mission like they had their previous ones. They were ambushed during the mission, and were trapped by three people who could copy their identities, smells, and thoughts. Working together, the group escaped from a cave-in with the treasure, but discovered that Hinata had injured her leg. After realising that Naruto and Kiba argued too often while Hinata worried for the others too much, they headed into town to stop their copies. When they arrived at Konoha, Kiba defeated his and Hinata's copies, but the one of Naruto was still on the run and causing a lot of trouble. The three genin learned that the mission was a test to see if they could work together as a team, and that they passed it with honours.

Kiba's relationship with Akamaru was highlighted in the Kiba's Long Day episode. After Akamaru was infected with a biological weapon that caused him to go berserk, Kiba believed that Naruto was trying to find and kill Akamaru, and attempted to take Akamaru out of Konoha. Kiba eventually stopped resisting when he learned of Naruto and Hana's true intentions, but was paralysed by the prospect that their plan might still require them to kill Akamaru. He eventually regained his senses and appealed to Akamaru, and when Akamaru lunged, Kiba was able to administer the antidote, Kiba ended up severely injured. Kiba later noted that Akamaru had tried his best to miss anything vital and avoid killing Kiba.

Naruto, Hinata, and Kiba continued to be teamed together, proving successful in their missions to a haunted castle, escorting a man named Shin'emon, and providing back-up for Kurenai. In the last episode of the filler arcs, when some ninja tried to steal Gaara's power, Kiba and the rest of the Konoha 11 (minus Tenten who was away on another mission at the time) were sent to help the Sand ninja. Kiba and Chōji went to help Kankurō, in thanks for helping in the fight with Sakon and Ukon. Kiba defeated the enemy, and then they went to Gaara's aid.

Sasuke and Sai Arc
When Naruto returned to Konoha after rescuing Gaara, Kiba appeared riding on a much larger Akamaru, but said he hadn't noticed Akamaru's growth, due to spending so much time with him. When Naruto asked Kiba to go on a mission with him, Kiba was forced to turn him down due to a mission he and his team had already been assigned.

Twelve Guardian Ninja Arc
In the anime, after having a discussion with Sora, Kiba assisted in the defence of Konoha, when Kazuma's army attacked. He was shown fighting alongside Rock Lee and Chōji, and was eventually joined by Shikamaru Nara and Ino Yamanaka as the battle came to a close. Kiba led the team to where Naruto was confronting Sora. There, they tried to stop Sora, but all failed with their attacks. Kiba was healed by Ino, and, along with Chōji, they tried again to attack Sora. He, along with the others, was only able to watch the battle until it ended.

Hidan and Kakuzu Arc
In the anime, he can be seen at Asuma's funeral mourning his death.

Three-Tails Arc
In the anime, Team 8, led by Kakashi head out to find one of Orochimaru's hidden bases. Because they might encounter Sasuke, they were forbidden to tell Naruto about the mission. As the team neared Orochimaru's hideout, Kiba remembered his fight with Sakon and Ukon. When Hinata and Kakashi asked him if he was all-right, he replied to his team that he wasn't worried, and, since Shikamaru and Naruto had showed their new abilities against Akatsuki, it was now his turn to show his improvement, too.

When they arrived at the base, it soon began to collapse in on itself. Because of Akamaru, they were able to escape in time, and began looking for survivors. Kiba and Akamaru used their sense of smell to search the area and, along the way, they picked up on a high-pitched whistle. Although initially suspecting that the enemy might be using dogs, since normal people couldn't hear it, Kiba realised that it was an ultrasonic sound, used only by bats, which were spying on them. Their location exposed, they were soon ambushed.

Kiba decided to go after Nurari, because he thought he was the weakest, but Kigiri used a smokescreen which robbed Kiba and Akamaru of their sense of smell. Hinata told him to go, because he could end up hurt, but, Hinata got beaten easily by Nurari. Kiba managed to blow away the smokescreen with a repeated use of his Passing Fang and saved Hinata. The enemies retreated, but Team 8 was drawn into a trap set by Guren. Kiba fought several copies of Guren, until Naruto and the rest of Team 7 arrived to help them escape. Kiba and Akamaru led the rest of the team to Guren's location by following the bats, but, upon arrival, they were overwhelmed by a tidal wave created by the Three-Tails. Having lost track of Guren and her forces, the team was reorganised, with Kiba being added to a defence team with Rock Lee and Tenten and led by Yamato, which was meant to prevent intruders from interfering with the sealing of the Three-Tails.

When each team left to accomplish their tasks, Kiba started explaining to their team-mates about Guren's henchmen's abilities. When the team reached the lake Kigiri and his group rose from the water. After Tenten and Rock Lee's attack to Team Guren, knowing that Kigiri would use his smokescreen, Kiba sent Akamaru to use Dynamic Marking on the three. Kigiri then used his smokescreen (as expected). But because of the Dynamic Marking, Akamaru used earlier, Kiba and Akamaru easily found the three and finished them off with Fang Passing Fang. The team split in two, and Kiba went with Yamato to go with Kakashi's team and help them. After the unsuccessful attempt of capturing the Three-Tails, the group separated again, and Kiba joined a search team to find Naruto.

After learning that Naruto was inside the Three-Tails, Kiba was assigned the job of guarding the area from attackers. He was surprised to see that Guren's men had arrived again, and were perfectly capable of fighting. Surprised by the new enhanced power of the enemy, Kiba, along with the rest of the team, were defeated and nearly killed. He survived thanks to he and Akamaru being able to hide themselves underground, thus only suffering an injury in his leg. Kiba and his team were on the way to tell Kakashi about the new power of their enemies, but, on the way, Kiba and Akamaru found Sai, barely alive, so they helped him.

They arrived where Kakashi and the others had defeated Guren's henchmen; but, after another failed attempt to capture the Three-Tails, they retreated back. Later, Kiba and the others were given new orders from Tsunade to return to the village to formulate a new plan for dealing with the Three-Tails. During the night, before the team returned, Yūkimaru left, and the next, Kiba had a brief discussion with Naruto because of that. Being aware of Yūkimaru's departure, they still left the place, and returned to Konoha.

Itachi Pursuit Arc
Later, Kakashi formed the Eight Man Squad, which Team Kurenai then became a part of, in the hunt for Itachi Uchiha. When the mission was sidetracked, due to them being close to Sasuke's trail, Kiba managed to pick up on Sasuke's scent after Kakashi's ninken proved unable to. On the way, however, they encountered Tobi of Akatsuki, and proceeded to do battle with him. After Shino's attack missed, Kiba was the only one able to sense him, and tried to hit him, only to miss too (embarrassingly, Tobi, just stepped to the side to avoid him). They fought him together, but no-one was able to land a single blow.

Before Tobi disappeared with Zetsu, Kiba and the others noticed Tobi's Sharingan for their shock. They start chasing both of them, but as soon as they arrived, Sasuke was already collected by them. Kiba told Naruto that there still was a little trace of Sasuke's scent; however it was already too late. Because of this, the mission ended in a failure.

Invasion of Pain Arc
During the assault, and the chaos created by Pain, Kiba was together with his team-mates, watching the disaster. Kiba then joined his mother in fighting the Preta Path, because of the advantage he had on it thanks to his proficient taijutsu. The Preta Path flees. In the anime, before the Preta Path escapes, Kiba and Akamaru used the Dynamic Marking so that they could track him. Before they leave, Kiba worries about the injured medical-nin but as Katsuyu tells him she will take care of them; Tsume and Kiba then continue chasing the path. Just as it was about to be caught, it was summoned away by the Animal Path, so that Pain could use Shinra Tensei. Kiba, his mother, and their dogs were caught in the Shinra Tensei that destroyed the village. He appeared to have suffered significant injuries because of a giant column that is about to fall down on him; his mother told him to hang in there until help arrived but he's able to get it off and pushing it away with his legs. He was later seen again with Katsuyu, watching the battle of Naruto against Pain, noting that the Konoha ninja should just put their faith in Naruto. Kiba was next seen along with all his friends, thanking and celebrating Naruto's victory.

Five Kage Summit Arc
Afterwards, he was seen rushing to Naruto, Sakura and Kakashi, informing them that Tsunade had been dismissed as Hokage, and that Danzō was now the acting Sixth Hokage. He also informed them that Danzō had given permission for Sasuke to be disposed of as a missing-nin. Kiba is then seen along with all his friends in a reunion; but because of Ino's crying over Sasuke's status as an international criminal, Kiba gets upset and tells her to stop. When Tenten defends Ino, he stands his ground and states that crying will change nothing to the established facts.

As a request from Sakura, Kiba and Akamaru accompany her along with Sai and Rock Lee to the Land of Iron in order to search for Naruto and confront him. He comments to Lee that compared to Ino, Sakura looked so determined, but when they do catch up with Naruto, it will all get awkward when Sakura talks to him. Kiba also states that because this is a top-secret mission, it is all on him to not only track Naruto, but also to make sure they are not being followed by Root agents or other enemies. Kiba and the others immediately arrive in the Land of Iron and find Naruto for Sakura to speak with him. Kiba stays present in Sakura and Naruto's talking but as promised to her, he or neither their friends, would interfere. However, he became increasingly irritated by what Sakura was saying to Naruto, knowing full well that she was not telling Naruto the truth in their talk and that she lied about telling Naruto their plans about Sasuke, yet still did not speak against it.

Kiba questioned Naruto about why Sasuke was with Akatsuki if Itachi already died; but received no answer. He then quietly asked Sakura if they should tell Naruto the truth, but Sakura stomped his foot and announced they're returning home. Immediately after, Sakura asked Kiba for help with a new job; tracking Sasuke and going after him. However, he became angry that Sakura had been lying to Naruto despite her protests. He then proclaimed that she takes Naruto far too lightly before finding Sasuke and Tobi and telling Sakura their position. Kiba then became stunned at Sakura and Sai's betrayal as Sakura prepared to knock them out to fight Sasuke herself. Annoyed he stepped back with Lee to allow the two of them to fight it out as Sai revealed Kakashi's orders for them to stop. Refusing to listen, Kiba attacked Sai with Lee, yet were quickly restrained by Sai's ink snakes. But before Kiba could free himself, they all got knocked out when Sakura took advantage of the situation to unleash powerful smoke bombs so that she could face Sasuke alone. Kiba and the others were soon found by Kakashi. Kiba, still barely conscious, told Kakashi which way Sakura went. Kakashi then moved the young ninja to a safer location before pursuing Sakura.

Soon after being awakened, Kiba reproached how Sakura and Sai's actions enabled Sasuke to escape again. Opting to return to their village, they met up with the rest of Konoha 11. Naruto then explained to them what happened at the summit. Acknowledging how Naruto practically became a legend after defeating Pain, Kiba believed Naruto let Sasuke slip away even though Naruto continuously denied the claim. Naruto also reinstated, much to Konoha 11's discontent, that he was the only one allowed to fight Sasuke.

Shinobi World War Arc
Kiba, alongside Hana, Shino and Ino, is placed in the Fifth Division to combat in the Fourth Shinobi World War, joking that if he does a great job, he might become Hokage. He is reprimanded by his sister who tells him that he should not take war so lightly.

Kiba leaves with the rest of his division, but soon enough, Mifune sends him, along with other ninja, to backup Kitsuchi's division. As the Zetsu are taken from the earth, Kiba rushes against them along with his sister, using his Fang Passing Fang. After the first day of fighting, Kiba is seen alive with Akamaru, along with Shino, Hinata, and Neji.

After night falls, Kiba, along with Neji, act as lookouts for enemy attacks. Neji later collapsed due to over-use of his Byakugan. Worried, Kiba told him that he should visit the medic compound to get treatment and that he would take over the watch. Neji however refuses to go claiming that he was fine. Kiba told him that injuring himself on the battlefield, wouldn't impress anyone to which Neji retorted telling him to shut up again, but faced Akamaru when saying this. Kiba then tells him that his state was so bad that he isn't even capable of differentiating him from a dog.

The next morning, Kiba and the other shinobi resumed fighting the White Zetsu Army clones amidst the confusion due to the latter's transformation and infiltration into their ranks. During this time, he and Neji both fought their newly reincarnated opponents, Sakon and Ukon and Kidōmaru respectively. With the power he gained over the timeskip, Kiba easily managed to destroy Summoning: Triple Rashōmon and defeat Sakon and Ukon. However, Kiba, Neji, Shikamaru and Chōji were trapped in a strange technique that the Sound Four unleashed before they could be sealed. Kiba's body was left in a comatose state while his soul was sent to a new location where it was reanimate within a large barrier. Inside, the inhabitants are able to battle normal. However, the Sound Four inform their enemies that in time, their actual bodies' halted chakra flow will eventually cause them to die. In addition, killing the Sound Four will not undo the technique. Despite the initial stalemate, the Sound Four's enhanced Cursed Seals grow even stronger from their accumulated malice, quickly overwhelming the Konoha ninja. Seeing that, Shikamaru begins to intentionally provoke them, knowing that Naruto's new senses would pick up on it. Eventually, Naruto finds them and breaks through the barrier, allowing Inoichi, through a telepathic connection, to release the technique and restore Kiba and the others to their bodies. Upon awakening, Kiba thanks Shino for his efforts in save them.

Later, calling out to Neji in the heat of battle, Kiba told him that Hinata was in trouble. Neji failed to save the nearest Hinata from an Iwa-nin only to discover that Hinata was a White Zetsu clone. As Kiba continued toward the real Hinata, he chastised Neji for going the wrong way and told Neji to follow him. They arrived in time to see a Naruto clone save Hinata. He and Neji were initially suspicious of the clone because he smelled and looked different than before, hence why Kiba didn't notice him. Kiba criticised Neji for not mentioning seeing Naruto sooner, but Neji claimed even Naruto's chakra signature was different. Hinata convinced them it was, indeed, Naruto, and Naruto then mobilised with them to finish off the rest of White Zetsu clones. After being informed by Inoichi from HQ that Naruto and B were fighting the "masked Madara", Kiba and the rest of the Konoha 11 rush to his aid. As he runs, he states that he had marked Naruto as a rival a long time ago and that he should handle things there until he arrived.

Ten-Tails Revival Arc
Finally arriving on the battlefield, Kiba told Naruto to not start acting tough just because Hinata was there after he echoed Hiashi Hyūga praise of the fact that Ino was able to veer the Tailed Beast Ball off-course. With that, Kiba and the other members of the Allied Shinobi Forces stood to face their opposition. Later as the Alliance's counter-attack was launched, Kiba and Akamaru are buffeted by the Ten-Tails who had just reached maturity and was emerging from the hole it had been trapped in. This caused Kiba to exclaim that the situation was getting frightening. After learning of Neji's death, Kiba later stood alongside Chōji and Ino, and was shocked by Chōji's rapid gain of weight after receiving Kurama's chakra. He later caught Ino after she performed the Mind Body Switch Technique on Obito Uchiha, surrounded by his own veil of Kurama's chakra, and asked Ino if she was okay, to which she confirmed after she regained consciousness.

Kiba and Akamaru later charged at the Uchiha and the Ten-Tails where their combined effort was enough to sever Madara and Obito's connection to the beast and force them to retreat to the ground. Kiba was later shocked by Minato's appearance on the battlefield, and later Sasuke's. He and the other Konoha 11 shinobi surrounded Sasuke and Kiba angrily asked what he was doing here. When Sasuke declared that he was going to be Hokage, an outraged Kiba chastised Sasuke asking him what he thought the title of Hokage was. With the reunion of Team 7, Kiba yelled that it will be he who would become Hokage, and not Sasuke. Shino declared that nobody was listening to him, while Hinata acknowledged his claim. He then rushed towards the Ten-Tails with his friends. Not to be outdone by Team 7, Kiba lead his team forward, revealing that he can perform the Shadow Clone Technique. Naruto saw it as no big deal, as he was able to do it years ago, but he then observed that the clone, Akamaru and Kiba himself have transformed into a giant three-headed wolf. In his transformed state, Kiba performed the Tail Chasing Fang Fang Rotating Fang technique, completely ripping rows upon rows of Ten-Tails' clones apart. He then witnessed Naruto and Sasuke's combined attack on the Ten-Tails as he urged them on.

With the situation looking grim as the Alliance was trapped in a barrier with a Tailed Beast Ball-firing tree, Kiba and the other shinobi soon found themselves shrouded in the previous Version 1 mantles again. He and the others subsequently found themselves on the outside of the barrier, escaping the near-fatal attack thanks to Naruto and Minato's action. The ever-competitive Kiba was irritated by the fact that Naruto could achieve such a feat, even though Hinata tried to explain the situation to him.

As Obito unleashes the final form of the Ten-Tails, the Shinju, it begins decimating the battlefield, killing countless ninja. Hashirama Senju has Ino Yamanaka everyone link-up telepathically to try and rally them. While Hashirama's words fail to inspire anyone, Naruto's senjutsu-enhanced Tailed Beast Mode combined with Ino's telepathy causes his emotions and personal memories to be transferred to everyone. Kiba is surprised to see how much Naruto is still affected by failing to bring Sasuke back from their mission three years ago. When Shikamaru later recovered, Kiba rebuffed Shikamaru's statement of becoming Naruto's adviser, believing that Shikamaru would become his if he takes the position of Hokage himself. Responding when Naruto called for them telepathically, Kiba, the other Konoha 11 shinobi and Sai are shocked when Naruto's Tailed Beast Mode mantle forms around them as well when he enters one of Kurama's tails. His directives clear, Kiba and the others used the Rasengan, which Naruto had formed to break down Obito's defence and give Sasuke and Naruto a clear shot at attacking their opponent. Kiba and the others who had all reverted to their Version 1 mantles aid Naruto and the others in wresting the tailed beasts' chakra from Obito's control as Kiba boldly stated that Naruto wanted them to help so they would do so until the very end.

Return of Madara Arc
Though they are able to defeat Obito, another threat soon arose as Kiba and the rest of the Alliance was confronted by Spiral Zetsu who overwhelmed them with a massive animate statue. As the Alliance struggled against this new threat, Kiba smelled Naruto close by. Realising Naruto was in danger, he asked Hinata to take a closer look with her Byakugan.

Naruto: Shippūden the Movie
Kiba made a small cameo before Team 7 was being called up, Team 8, except Shino, were seen running through the streets.

Naruto Shippūden 3: Inheritors of the Will of Fire
Kiba was seen with Konoha 11 eating barbecue to celebrate Naruto and Sai's recovery. When Hiruko announced a fourth ninja war will occur, he was seen with Konoha 11 except Naruto assigned by Tsunade to secure the village. After Naruto and Sakura left the village to go after Kakashi, Kiba and the gang were sent to stop them. While pursuing them, Kiba and his team were soon attacked by Ni and her beast. Kiba uses his Fang Passing Fang to break the door and allow Naruto and Sakura to go and continue rescuing Kakashi since he believed in their cause. Soon after, Kiba starts fighting against Ni in her new beast form, being a distraction as Shino prepared his trap.

After San summons and fuses himself with her and Ichi, Kiba along with the Konoha 11 starts fighting the new powerful beast. Kiba again uses his Fang Passing Fang and pierces right through the beast's wings, making it unable to fly. Kiba made his last appearance along with the rest of Konoha 11, overhearing Kakashi and Naruto's weird conversation and wondering about Kakashi's preferences.

Naruto 6: Road to Ninja
Kiba first appeared alongside his friends battling several Zetsu clones disguised as deceased Akatsuki members. Later, in the alternate world, a different Kiba appeared compared to the one that Naruto and Sakura know. This Kiba is more humorous and a cat lover who hates dogs, like Akamaru. He also has more cat-like mannerisms and his clan facial marks are changed slightly to being several marks lined up.
