Kiba Inuzuka

is one of the main supporting characters of the series. He is a Chūnin-level Shinobi of Konohagakure and a member of the Inuzuka Dog-User clan, as well as a member of the Chūnin team, Team Kurenai, along with Shino Aburame and Hinata Hyūga. Kiba is usually seen with and fights in collaboration with his partner, Akamaru.

Background
At a very young age, Akamaru was given to Kiba by his mother, Tsume Inuzuka, and both of them became the best of friends. Before entering the Ninja Academy, Kiba and Akamaru played a lot together, causing Tsume to get 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 or otherwise be testing the patience of Iruka Umino, their Chūnin-sensei.

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.

Personality
Kiba is often short-tempered and impulsive (in stark contrast to his teammates Shino and Hinata), and can be prone to making mistakes when he becomes agitated in battle. The fact that he enjoys combat, as well as a habit of showing a joyful smile when facing a particularly strong opponent, indicates that he is willing to risk his life for a mission, and is rather bloodthirsty. He deeply cares 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 Inuzuka, and remains fiercely loyal to the Inuzuka clan.

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 gets along well with Hinata, 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 apparently likes to tease Hinata about her affections for Naruto. These teasings usually consist of telling her that Naruto is nearby, or just mentioning her reactions to him to other people, much to her embarrassment.

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, Naruto, Choji and Shikamaru skipped classes together. Those three seem to be some of the first true friends he made in the village.

Appearance
Kiba's personality and jutsu style are further enhanced by his wild appearance. While clearly human, he has several physical traits more akin to animals. Like the rest 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 distinct red fang markings of the Inuzuka clan on his cheeks.

During Part I, Kiba's attire consisted of dark greyish-brown pants and a grey hooded coat with a blue forehead protector and blue sandals. During Part II, his outfit changed to a form fitting black jacket and pants with a black forehead protector and black sandals.

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 traumatized by the sight.

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 blowing off in Kiba's face (overwhelming his sense of smell and disorienting him), defeated him with the first use of 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 recognize him), leaving him unable to assist Konoha's ninja in the invasion.

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 scent 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 his new technique Man Beast Combination Transformation: Double-Headed Wolf. Despite using this technique and their Dual Wolf Fang, the brothers were able to block their attack with Summoning: Rashomon.

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, 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. He typically fought with Naruto over who should lead the team. In one episode, Episode 158: ''Follow My Lead! The Great Survival Challenge'', 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 Yamano. His time with them was not covered much, except that he was doing better than Naruto.

During the Hunt for the Bikochu arc, Kiba, Hinata, Shino, and Naruto were sent on a mission to find a Bikochu Beetle which could be used to track down Sasuke Uchiha. They went to the forest where the Bikochu 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 Bikochu. Kiba and the others went to rescue her, but tried to trick the Kamizuru into giving them Hinata before they gave up the Bikochu. 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 blew off and made the Bikochu useless.

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 Treasure Hunt 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 realizing 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 honors.

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 paralyzed by the prospect that their plan might still require them to kill Akamaru. He eventually regained his senses and appealed to Akamaru, causing Akamaru to regain enough of his true self to avoid killing Kiba, and allowed him to administer the antidote.

Naruto, Hinata, and Kiba continued to be teamed together, proving successful in their missions to a haunted castle, escorting a man named Shinemon, 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 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.

Fire Temple arc
In the anime, after having a discussion with Sora, Kiba assisted in the defense 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.

Three-Tails Arrival arc
In another of the anime-exclusive arcs, Team 8 (minus Kurenai) was led by Kakashi 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 alright, 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 realized 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, and, after feeling helpless, Kiba managed to blow away the smokescreen with a repeated use of his Piercing Fang. 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-Tailed Beast. Having lost track of Guren and her forces, the team was reorganized, with Kiba being added to a defense 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 teammates about Guren's henchmen's abilities. After Rock Lee and Tenten's attack, Akamaru used his Dynamic Marking on the enemies, which continued to work even in the scent-removing smokescreen, and Kiba and Akamaru then finished them off with their Dual Piercing 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 was defeated along with the rest of his team, but 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.

Hunt for Itachi 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. 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 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 teammates, 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 body retreated, for Pain was in need of its technique, and Kiba, his mother, and their dogs were caught in the Shinra Tensei that destroyed the village. He appeared to have suffered significant injuries, and his mother told him to hang in there until help arrived. 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. Then Kiba is 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 Sai, Kiba goes with him, Sakura 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, yet still did not speak against it.

Kiba questioned Naruto about why Sasuke was with Akatsuki if Itachi already died; but recieved no answer. He then quietly asked Sakura if they should tell Naruto the truth, but Sakura stomped her foot and announced they're returning home. Immediately after, Sakura asked Kiba for help with a new job; tracking Sasuke and going after him.

Speed & Agility
He is adept in a form of taijutsu in which the moves resemble capoiera or breakdancing. During Part I, during the Chūnin Exam arc, it has been showed that Kiba has fast movements, and stated by Naruto during their fight, his great speed makes him hard to hit. 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.

Enhanced Senses
As a member of the Inuzuka clan, Kiba possesses enhanced senses of hearing and smell. His most powerful sense, and weapon, is his sense of smell. In Part II, during the Hunt for Itachi Uchiha Arc, he stated that his nose was stronger than any ninja hound, a feat that impresses Kakashi, and with which he replied that all the Inuzuka clan must be proud of him. But Kiba also replied to Hinata that, despite his nose being a great advantage, his powerful sense of smell was like a double-edged sword, rendering him vulnerable to strong odors. During his Man Beast Combination Transformation: Double-Headed Wolf, he is able to follow his enemy with his sense of smell after Akamaru uses Dynamic Marking.

Inuzuka Clan Abilities
He is proficient in several canine-based jutsu. His battle style is usually a combination of taijutsu enhanced by his special clan jutsu. He fights and attacks with the ferocity of a beast, utilizing his sharp claws and other beast-like abilities that he gains from his Four-Legged 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 into a giant two-headed wolf, where they can use their Dual Wolf Fang, which is almost impossible to avoid, let alone block.

According to the third Naruto databook, Kiba learns 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 jutsu.
