Naruto Uzumaki

is the main character of the series. Although he is only a Genin of Konohagakure, he is trained as a sage and thus is one of the village's most powerful ninja. He is a member of Team Kakashi, and the jinchūriki of the Nine-Tailed Demon Fox.

Background
Naruto was born the son of Minato Namikaze, the Fourth Hokage, and Kushina Uzumaki. Before his birth, they had decided to name him after the main character in Jiraiya's first book, hoping their son would be a great ninja as the character was. This made Jiraiya Naruto's godfather. Soon after his birth, however, the Nine-Tailed Demon Fox attacked Konohagakure. To save the village, Minato engaged the Nine-Tails in mortal combat and sealed it into Naruto's body, believing his son would someday have use for it. Minato died afterwards, leaving Naruto to grow up knowing nothing of his parents. He received his mother's last name since Hiruzen Sarutobi, the Third Hokage, felt that it was best that nobody knew he was related to the Fourth Hokage.

Before Minato died, he asked that the villagers of Konoha view Naruto as a hero who had helped to stop the Nine-Tails. Few did as he asked, however, instead openly resenting him for containing the monster that had destroyed their home. In light of this, the Third Hokage decreed that nobody should ever speak of the Nine-Tails sealed within Naruto, hoping that their children would not resent him as they did. The children, however, followed their parents' lead, despite not knowing why. Naruto was forced to live confused over why the villagers hated him so, and strived to win their recognition. Iruka Umino would be one of the few exceptions, who was always compassionate to Naruto's plight. For this, Naruto came to view Iruka as the father-figure he never had.

Personality
Before graduating from the Academy, Naruto had a craving for acknowledgement. During his days as an academy student, Naruto would play pranks all around the village in an attempt to be recognized by its inhabitants. He would also tell everyone who doubted him on a near-constant basis that he would one day become Hokage. As he told Iruka, he wished to achieve this rank in order to be recognized by those around him, and to have the responsibility of defending them.

Even after graduating, Naruto was still determined to be recognized, and became the "Number One Loudest, Unpredictable, Hyperactive Knuckleheaded Ninja of Konoha", as described by Kakashi Hatake. As the series progressed, with Naruto making more and more connections with others, his reasons for wanting to become Hokage underwent a change, having less to do with the desire for recognition, and more to do with wanting the strength to protect his home and the people close to him.

Naruto's exuberant personality and fiery desire for self-improvement strongly impacts the lives of those around him. At the beginning of the series, Naruto befriended Konohamaru Sarutobi, the grandson of the Third Hokage, and it is through his brief tutelage that Konohamaru learned that the path to success is through plenty of hard work. Kakashi described this as Naruto's "unique power", as he seems to change the world views of everyone he meets, and inspires courage for the future within them. This is most prominently shown when Naruto earned the trust of Nagato, the leader of Akatsuki, and one of the main antagonists of the series.

As mentioned above, Naruto is characterized as being hyperactive; he is typically exuberant, easily excitable, impulsive, and suffers from a short attention span. This is supported by Asuma Sarutobi in the 'Fire Temple' arc in the anime, describing Naruto as being the type who doesn't think before acting, similar to Sora. Asuma also identifies Naruto's personality type and fighting style, like Sora's, as being a 'power type' (types that are best suited to 'charging straight in') and are best effective in battle when sent in first, in the front to 'clear a path' through the enemy's defensive line, making a way in after them for the rest of the team. While raw power is one of his strengths, Naruto has begun to learn in recent chapters that it is something that he needs to temper with focus in order for it to become truly effective.

According to Kakashi, Naruto is someone who learns through his body. Naruto is relatively naive, being slow to understand a jutsu's principles, and often requiring a dumbing-down of an already dumbed-down analogy in order to grasp what is being explained to him. This assumes he is able to keep his attention long enough, as he commonly seeks to change the subject in light of his ignorance, outwardly insisting that he already gets the concept. Though he retains this confidence in himself to great degrees, loudly proclaiming that he will master whatever technique he is learning in a fraction of the usual time, Naruto will not hesitate to ask for help if he needs it.

As an extension of his naivety, Naruto has a number of childish traits. His pajamas always include a comical black nightcap with eyes and teeth, and he keeps his money in a chubby, green-frog wallet he affectionately calls "Gama-chan". He almost exclusively eats ramen, and is a frequent customer at the Ichiraku Ramen Bar. He has a natural affinity for perverted ideas and jutsu, something he tends to be reprimanded for by Sakura, and which is only brought to new levels after meeting Jiraiya. He also smiles near-constantly, which, during his childhood, was to mask the sadness of his lonely life. Those who are closest to him are able to recognize when his smile isn't genuine.

However, when the situation calls for it, typically when someone dear to him is in trouble, Naruto can be very serious, and will instantly come to their aid. This is most commonly seen in the series through his interactions with his teammates, Sasuke Uchiha and Sakura Haruno. With Sasuke, Naruto views him as a brother, and throughout Part II strives to bring him back to Konoha, despite his willing defection from the village. With Sakura, Naruto has a long-standing crush on her, and will do all in his power to make her happy, even if it is at the expense of his own happiness. Sai has indicated that this dedication has progressed to the point of love.

After talking with his father, defeating Nagato and having a truce with him and Konan, Naruto came to understand the downside of revenge, and desired to stop Sasuke from it even more. Also, Naruto tried to stop the Kumo-nins from exacting their revenge against Sasuke, for this would only create a cycle of hatred. It appears that Naruto is becoming increasingly desperate in his quest to save Sasuke, as he was willing to beg on his knees before the Raikage to forgive Sasuke for his crimes and even take physical abuse over selling him out.

Appearance
As stated by Jiraiya, Naruto bears a striking resemblance to his father. Naruto possesses similar blue eyes and spiky blonde hair. Naruto is regularly seen with an upbeat and eager persona, always eager for something such as learning a new technique or a hot bowl of ramen. A trait regularly mentioned, that easily angered him, was his short stature even for his age. During Part I, he was one of the shortest in his graduating class, second only to Hinata. During Part II, he had a significant growth spurt that was noticeable to all, as first mentioned by Sakura, who stated he was now much taller than her. Even Kiba Inuzuka stated that Naruto had become a 'giant', and Temari remarked that the 'shorty' had grown dramatically upon seeing him. Also, earlier in the series, Naruto used to squint his eyes a lot when confused, but stopped after a while.

Naruto and the Nine-Tailed Demon Fox


As the jinchūriki of the Nine-Tails, both Naruto's mind and body are occasionally influenced by it. Physically, Naruto has some of the fox's characteristics, such as whisker-like marks on his cheeks and larger than normal canines. He also has increased stamina and healing abilities, which allows him to recover from major injuries within a day, and minor injuries within a few seconds. Mentally, Naruto remains largely unaffected, save for a few animalistic traits that slip through, such as his occasional tendency to leap between trees on all fours. Since the Nine-Tails was sealed inside Naruto at birth, it is unclear just what parts of his personality it has had an effect on; however, it could explain Naruto's impish side for pulling pranks to gain attention, as well as his stubbornness to never back down from a challenge.

Naruto's normal chakra level is considered extremely high, partially because of the Nine-Tails. Even without directly drawing upon it, a small amount of the Nine-Tails' chakra is always mixed with his own. Jiraiya once commented upon the fact that Naruto's body is much too small a vessel to properly contain the chakra of the Nine-Tails, and his body will instinctively reject the bulk of it due to the damage it would cause. Ebisu implied that Naruto's poor chakra control stems from this, as a portion of his chakra is used to reject the Nine-Tails' overwhelming chakra. What chakra that does not get suppressed by Naruto's body is assimilated by his chakra, making Naruto's usual chakra capacity astronomically high for someone in his age group (or indeed anyone above his age group). According to Kakashi, Naruto's regular chakra level is about four times of Kakashi's own. As such, he is naturally suited to jutsu that use a large amount of chakra, such as his signature jutsu, Shadow Clone Technique. While most ninja are only capable of creating a few clones safely, due to the jutsu's hazard of equally dividing the user's chakra among the clones, Naruto is able to create hundreds while maintaining a decent supply of chakra in each one.

The Nine-Tails' chakra usually comes to Naruto during life-threatening or other stressful situations, given to him by the Nine-Tails itself to ensure its survival. Naruto eventually learns to contact the Nine-Tails and demand some of its chakra, which it seems to comply to out of amusement. The reason Naruto is able to access its chakra is because of the unique way in which it was sealed. Though the Nine-Tails remains trapped within Naruto, its chakra can leak out through the seal and mix with Naruto's. The Nine-Tails' near-limitless supply of chakra becomes an invaluable weapon for Naruto, often turning the tide of a difficult battle in his favour. Though useful, expanding the magnitude of his other abilities, Naruto cannot handle too much of the Nine-Tails' influence. As he draws upon additional amounts of the Nine-Tails' chakra, "tails" are produced, and from the fourth tail onwards he is reduced to animal instincts, no longer being able to differentiate between friend and foe. Although he usually has success from stopping himself from getting too far, once the fourth tail is attained he needs outside assistance to force the Nine-Tails' influence to recede.

Part I


The series begins with Naruto, labelled as his classes 'Dead-Last', once again failing to graduate from the Ninja Academy. Disappointed that his plans of becoming Hokage have hit another hurdle, Naruto was approached by one of his instructors, Mizuki. Mizuki told Naruto that, if he could steal the Scroll of Seals from the Hokage Residence and learn one of the jutsu written on it, then he would be allowed to graduate. Naruto did so, and began struggling to learn the Multiple Shadow Clone Technique, unaware that the village was now looking for him.

Iruka tracked him down, and discovered Mizuki's involvement in the theft, realizing that Naruto had been duped by Mizuki, in an effort to steal the scroll. Mizuki attacked them, and told Naruto about the Nine-Tails sealed within him, claiming that Iruka hated him because of it. When Iruka risked his life to protect Naruto, however, Naruto realized that Mizuki's earlier words were a lie, and created hundreds of shadow clones to beat Mizuki to a pulp. For mastering such a difficult technique, Iruka allowed Naruto to graduate.

In the days to come, Naruto befriended Konohamaru and became his on-off teacher, showing him how to perform a variety of both perverted and useful jutsu throughout the rest of the series. He was also assigned to Team 7, where he was partnered with Sasuke Uchiha and Sakura Haruno, under the leadership of Kakashi Hatake.

As the team's first order of business, Kakashi gave them a test to see if they were ready to become Genin. He had the three of them try to take the two bells he kept on his person, the goal of the test being to place teamwork above the fact that they couldn't all have a bell. Although they initially failed miserably, all trying independently to take a bell, they eventually decided to work together, allowing them to pass.

Land of Waves arc
After completing a number of simple, uneventful missions, Team 7, at Naruto's insistence, was assigned the somewhat more difficult C-rank task of escorting Tazuna to the Land of Waves. When they were attacked by the Demon Brothers along the way, who tried to kill Tazuna, they realized that there was more to this mission than a simple escort. Tazuna revealed that his country was under the control of Gato, who had left the people poor and unable to afford the more accurate A-rank mission payment. By building a bridge that would connect the Land of Waves to the mainland, Tazuna hoped to free the country from Gato, prompting Gato to try and kill him. Team 7 decided to help Tazuna, and act as his bodyguards until the bridge was completed.

They were soon attacked by Zabuza Momochi, another of Gato's assassins, who engaged Kakashi in battle. When Zabuza captured Kakashi, he encouraged his team to escape with Tazuna. Having been of little use during the battle with the Demon Brothers, Naruto resolved to help Kakashi. With Sasuke's assistance, they were able to free Kakashi, who in turn almost defeated Zabuza. However, Haku, disguised as a hunter-nin, intervened, and appeared to kill Zabuza first, in actuality only putting him in a death-like state in order to get him to safety. Kakashi suspected that Zabuza was still alive, and gave Team 7 a Tree Climbing Practice to improve their chakra control. Naruto and Sasuke developed a competition over the exercise, each determined to complete the training first, and subsequently motivating each other to do better.

While Naruto was resting from training one day, he encountered Haku, unaware that it was the same boy he had encountered earlier. The two had a conversation about those who were precious to them, and the lengths they would go to protect them. After Haku left, Naruto finished the training, but was left so tired that the rest of Team 7 allowed him to rest the next day as they went to escort Tazuna. When he woke up, he went to assist them, only to find that they were in the midst of battle with Zabuza and Haku.

Naruto went to help Sasuke in his battle with Haku, but they were both trapped by Haku's Demonic Ice Mirrors (because Naruto was an idiot and thought it'd be a good idea to "sneak in to help"). When Haku tried to use a volley of needles to kill Naruto, Sasuke stepped in to protect him, appearing to die instead. Enraged by the apparent death of Sasuke, Naruto tapped into the Nine-Tails' chakra, allowing him to destroy the ice mirrors, and subsequently defeat Haku. Before he could kill Haku, however, the mask he was wearing broke away, revealing the face of the boy Naruto had met earlier. Naruto stopped himself, but Haku asked that he should finish the job, since he could no longer be of use to Zabuza. Although Naruto tried to comply, Haku stopped him at the last minute, and went to help Zabuza. When Naruto realized what had happened - that Haku had given his life to save an ungrateful Zabuza - an outraged Naruto reprimanded Zabuza for not appreciating Haku's actions. Touched by his words, Zabuza killed Gato to repent in an effort to do Haku justice, but died of his wounds. The bridge (now named the Great Naruto Bridge) was completed, and the Land of Waves was saved, so Team 7 (with a recovered Sasuke) returned home.

Chunin Exam arc
After returning home and completing a few other simple missions, Team 7 was entered into the Chunin Exams. In the first phase, a written test, the participating Genin were tasked with completing the test by cheating, all the while being sure not to get caught. Though the rest of the examinees realized this, Naruto did not, and struggled to answer the questions, which were far beyond his comprehension. Hinata Hyuga, who was sitting next to him, offered to allow him to copy off her paper, but he refused, in fear that she would get caught. Naruto was forced to rely on getting the tenth question correct to pass. When faced with the prospect of correctly answering the question to proceed, failing and never being allowed to take the test again, or giving up to try it again during the next exams, Naruto insisted on answering the question, stating that, even if he got it wrong, he would still become Hokage. The willingness to face the unknown being the answer to the tenth question, Naruto and the rest of Team 7 were allowed to proceed to the second phase.

For the second phase, Team 7 was sent into the Forest of Death with one scroll, tasked to obtain a second scroll from another team and arrive at the forest's centre before the phase ended. Soon after entering the forest, they were attacked by Orochimaru, who immobilized Sasuke and Sakura with his murderous intent. Before Sasuke could forfeit their scroll in exchange for their lives, Naruto intervened, fighting Orochimaru by tapping into the Nine-Tails' chakra. Orochimaru rendered Naruto unconscious by restricting access to the Nine-Tails' chakra, but Naruto's courage inspired Sasuke to fight in his place. After Orochimaru was driven off and Naruto awakened, Team 7 encountered Team Oboro. After wasting a day trapped in the rival team's genjutsu, Team 7 was able to defeat them, take their scroll, and pass the round.

Because too many Genin teams had passed the second phase, a round of preliminary matches, where Genin faced each other in combat, were held to thin the field. After watching the first few rounds, Naruto was matched against Kiba Inuzuka, and his dog, Akamaru. Remembering Naruto to be talentless from their days in the academy, Kiba believed it would be an easy match. He and Akamaru double-teamed Naruto, who initially had difficulty with the match. After combining the Transformation Technique with his shadow clones to turn Kiba and Akamaru against each other, Naruto was able to remove Akamaru from the competition. When Kiba was about to defeat him, Naruto blew off, immobilizing Kiba and his heightened sense of smell, and making him an easy target for the Uzumaki Naruto Combo. Naruto won the match.

While watching the remaining matches, Naruto witnessed Neji Hyuga's ruthless treatment of his cousin, Hinata. Angered by Neji's actions, and his claims that Hinata was a failure who couldn't escape that fate, Naruto vowed to defeat Neji during the first round of the finals a month later. In the meantime, Naruto started training with Ebisu to improve his chakra control. When Ebisu was knocked out by Jiraiya, Naruto forced Jiraiya to train him in his place. Jiraiya, noticing that Naruto was the container of the Nine-Tails, and the restrictive seal Orochimaru had placed on him earlier, Jiraiya removed the seal to ease his chakra control. He then taught him how to take advantage of the Nine-Tails' chakra by showing him how to use the Summoning Technique to summon toads. Although having little success at first, Naruto was eventually able to summon the likes of Gamabunta in time for the final round.

When his match against Neji began, Naruto appeared to be at a disadvantage. Although he was able to overwhelm Neji with shadow clones, none of the clones could manage to land a hit. Convinced that Naruto was a failure that could not defeat a genius like himself, Neji used his Eight Trigrams Sixty-Four Palms to cut off Naruto's chakra supply. Determined to prove Neji wrong, Naruto tapped into the Nine-Tails' reserves and, revitalized, clashed with Neji. When the smoke cleared, Neji emerged, Naruto appearing to have been defeated. This, however, was only a shadow clone, and the real Naruto burst from the ground beneath Neji, to deliver an uppercut and defeat him. Neji was taken away, contemplating the fact that fate was not predetermined, since a failure could beat a genius, while Naruto watched the remaining matches. When Sasuke fought Gaara, he was envious of Sasuke's improvements, but the fight was interrupted by the beginning of the invasion of Konoha.

Invasion of Konoha arc
Naruto was put to sleep when the invasion began, but was awakened by Sakura so that they could go after Sasuke, who was pursuing Gaara in order to continue their fight. They caught up in time to stop Gaara from killing Sasuke. Intrigued by Naruto's abilities, Gaara forced him into battle by threatening to kill Sakura. With the power of the One-Tailed Shukaku sealed within him, Gaara tried to prove his existence by killing Naruto. Although Naruto could relate to Gaara's life as a jinchūriki, he was not willing to allow anything to happen to Sakura and Sasuke. With the Nine-Tails' chakra, he summoned Gamabunta, and fought Gaara, who by now had progressed to his full Shukaku form. Naruto was able to force Shukaku's influence to recede, and they exchanged final blows, Naruto emerging the victor. Perplexed that someone could find strength by fighting for their friends, Gaara retreated, while Naruto returned home with Sakura and Sasuke.

Search for Tsunade arc
After the failed invasion resulted in the death of the Third Hokage, Jiraiya was tasked with finding a Fifth Hokage. He convinced Naruto to come with him by promising to teach him a new jutsu. Along the way, they were met by Kisame and Itachi, two members of Akatsuki, who sought to capture Naruto for the Nine-Tails sealed within him. Jiraiya was able to draw them off, but Naruto was introduced to the organization that would become more of a problem for him in Part II. To prepare him for their future encounters, Jiraiya taught him how to use the Rasengan, a jutsu created by Minato. While Naruto was able to complete the first two steps of the learning process with little difficulty, he struggled to complete the third and thus master the technique.

Naruto and Jiraiya eventually found Tsunade, the ideal candidate for the position of Fifth Hokage. When she turned down the offer, and insulted all those who had previously held the title, an angry Naruto attacked her with an incomplete Rasengan. Although his effort failed to hit her, she was surprised by his progress and made a bet with him: if he could master the technique in a week, she would give him her necklace. He agreed, and started practicing, but in a week's time still had yet to finish the training. Disappointed, Tsunade met with Orochimaru, the murderer of the Third Hokage, and Naruto and Jiraiya tried to stop her from helping him.

Tsunade turned out to have no intention of helping Orochimaru, and fought him and his assistant, Kabuto. When Kabuto left her unable to fight, Naruto came to her aid. By using shadow clones to help him form it, Naruto was able to hit Kabuto with a perfected Rasengan, winning the bet. Amazed by his determination to keep to his word and to survive against a superior opponent, Tsunade gave him her necklace, drove off Orochimaru and Kabuto, and accepted the position of Fifth Hokage. They returned to Konoha, Tsunade confidently believing Naruto would someday become a great Hokage.

Land of Tea arc
In the anime, with Konoha having a shortage of elite ninja due to Orochimaru’s failed invasion, Tsunade was forced to use Genin for more dangerous mission than normally allowed. Team 7 (minus Kakashi who was assigned to another mission) was given an assignment of the escorting a member of Land of Tea's Wasabi clan through a dangerous annual race as it was rumored the rival Wagarashi clan had hired ninjas of their own to sabotage the Wasabi clan. Along the way, they met an arrogant teenager named Idate who openly showed his hatred towards ninja. He also showed off impressive speed by running away from Team 7 after conning them into paying his bill at a restaurant. Upon arriving in the Land of Tea and meeting the Wasabi Clan’s leader Jirocho, Team 7 was shocked to see Idate again and learn he was the man they were assigned to escort.

During the race, Naruto and Idate continued to show their dislike of each other. It was also revealed that Idate was actually the younger brother of Ibiki, and formerly a genin from the Leaf Ninja. They also encountered the three Rain ninja from the Chunin Exams. After defeating them, they encountered Aoi Rokusho, another former ninja of the Leaf Ninja who betrayed Konoha to join the Rain Village. He was also originally Idate’s teacher and the one responsible for Idate running away from Konoha. After barely surviving Aoi’s attack, Idate explained how after he was failed by Ibiki himself for the Chunin Exams, Aoi tricked Idate into stealing for him a special scroll and the Sword of the Thunder God. Being able to relate with Idate in both being taking advantage of and desperate to have approval from others, Naruto helped Idate regain his self-worth and continue the race.

While managing to catch up in the race, Aoi appeared again and used the Thunder Sword to initially overpower the Team 7. But thanks to Sasuke weakening the sword with his Chidori, Naruto was able to break it and defeat Aoi with his Rasengan. With the danger overcome, Idate was free to continue and win the race for the Wasabi clan. While returning to the village, Team 7 was escorted by Ibiki himself. While not openly stated, Ibiki was glad Naruto helped his brother grow as a man.

Sasuke Retrieval arc
After returning with Tsunade, Sasuke began to fall into the corruption set in place for him by Orochimaru. He began lashing out at Sakura and Naruto, not as teammates but as enemies, eventually defecting from Konoha in order to seek out Orochimaru for power. Under the escort of Orochimaru's Sound Four, Sasuke left to join Orochimaru, and Naruto joined a retrieval team that would bring him back. While the other members of the team dealt with the Sound Four, Naruto finally engaged in a fight with the Sound Four's fifth member, Kimimaro. However, he was not able to beat him. When he was about to be killed, he was saved by Rock Lee, who told him to continue the pursuit of Sasuke while he fought Kimimaro.

Naruto finally caught up with Sasuke in a place called Valley of the End, very near the border of the Land of Fire and the Land of Sound, and fought Sasuke. With Sasuke determined to kill Naruto in his quest for power, Naruto decided he would have to take the battle seriously if he was to bring Sasuke back. When Sasuke's drive to kill proved greater than Naruto's resolve of friendship in a 'fair' fight, Naruto tapped into the Nine-Tails' chakra to level the playing field. Sasuke, pushed to his limits, managed to develop the mature Sharingan, greatly overpowering Naruto. When Naruto, even with the Nine-Tails' chakra, was defeated, he tapped into the chakra even more, and a red aura of the Nine-Tails' chakra, in the shape of a fox, surrounded him. Sasuke then drew on the power of the second stage of his cursed seal to properly compete with Naruto. The two had one final clash, Naruto with his Rasengan and Sasuke with his Chidori. Sasuke struck Naruto, and effectively defeated him. After staring at Naruto's unconscious body, Sasuke couldn't bring himself to kill his best friend, and he simply continued on his way.

Although he failed to retrieve Sasuke, Naruto vowed to Sakura that he would someday bring Sasuke home.

Filler arcs
See: Filler arcs

After the anime of Naruto had concluded the Sasuke Retrieval arc, to make sure the anime did not over take Part II of the manga, the makers instead animated several filler arcs to take place before Naruto left for his three year training with Jiraiya. Naruto is sent on various missions with the other members of the Konoha 11, but while there is little character development for himself, the filler arcs tend to develop the supporting characters.

Rescue Gaara arc
When Naruto returned to Konoha, the remaining members of Team 7 were reorganized into Team Kakashi. As their first order of business, Kakashi gave them another bell test, this time the only goal being to take a bell, and that he would use his Sharingan against them. Although their abilities had improved, Naruto and Sakura were still unable to beat Kakashi, and it was only by threatening to spoil the end of the latest Icha Icha novel that they distracted Kakashi long enough to take the bells. Naruto reconnected with his old friends, who had all advanced to Chunin-rank, and then heard that Gaara, the new Kazekage, had been kidnapped by Akatsuki. Naruto and Team Kakashi set out for Sunagakure to save him.

Upon arrival in Sunagakure, Chiyo was added to Team Kakashi as an adviser, and they followed Akatsuki's trail. Along the way, they encountered a body-double of Itachi Uchiha, which engaged them in battle. Kakashi and Naruto teamed up in order to defeat the lookalike, before continuing onto the Akatsuki lair. There, they found Gaara's body in the possession of Deidara and Sasori. When Deidara flew off with Gaara, Naruto and Kakashi pursued him, leaving Sasori to Chiyo and Sakura. While initially unable to catch Deidara, Kakashi was able to use his Mangekyo Sharingan to distract Deidara, giving Naruto an opportunity to attack him and retrieve Gaara. Deidara escaped, and Naruto and Kakashi reunited with Sakura and Chiyo.

Although Sakura tried to heal Gaara, he had already died, a casualty of Akatsuki's tailed beast extraction-process. Angered that Gaara had died because he was a jinchūriki, something he had never asked for and had suffered because of his whole life, Naruto lashed out at Chiyo, the one who had sealed Shukaku into Gaara in the first place. To make up for what she had done, Chiyo, with the help of Naruto, restored Gaara to life, at the cost of her own. Gaara awakened surrounded by friends, and, after Chiyo's funeral, Naruto returned home with the rest of Team Kakashi.

Sai and Sasuke arc
During Sakura's battle with Sasori, she learned of a spy in Orochimaru's inner circle, an opportunity for them to find Sasuke after his years of absence. Kakashi was left hospitalized from overuse of the Mangekyo Sharingan, so Yamato was assigned to lead Team Kakashi in his place. Sai was also added to the team as Sasuke's replacement, but neither Naruto nor Sakura were able to accept him as such.

En route to the meeting place with the spy, Yamato tried to get the team to work together, although Sai's personality and disdain for his predecessor caused only conflict amongst the team. When they arrived at the meeting spot, they found that the spy was Kabuto. Yamato, disguised as Sasori, spoke with him, but they were interrupted by the arrival of Orochimaru. Kabuto, in turn, turned against Yamato, who was forced to call Naruto and the others for back-up. Surprised to see Naruto, Orochimaru wondered aloud if Naruto had become as strong as "his Sasuke". Enraged that Orochimaru had spoken as if Sasuke belonged to him, Naruto entered a three-tailed transformation, and attacked him.

While a fair match, Orochimaru was able to evade Naruto's attacks. Further provoked by his inability to land a debilitating blow, Naruto advanced to the four-tailed form, losing his sense of self in his anger. Now a danger to Orochimaru, Naruto was forced back so that he could switch targets, his first being Sakura. Yamato restrained him before he could do any real harm, and forced the Nine-Tails' influence to recede. When he woke up, they found that Sai had joined up with Orochimaru. They followed him in the hopes that he would lead them to Sasuke, and to see what he was up to. During a break, Yamato took Naruto aside, and told him of how he had attacked Sakura, encouraging him not to rely on the Nine-Tails if he really wanted to protect those close to him.

When they arrived at Orochimaru's hideout, they infiltrated the lair, and captured Sai. Exposed, Sai revealed that his superiors had sent him to help organize another invasion of Konoha. He was restrained for his treachery, while the others went looking for Sasuke. Sai, having earlier met Sasuke, asked why Naruto was so determined to bring him back. Naruto explained that the two had a bond that couldn't be broken, and that he would risk his life to protect this bond. Intrigued, Sai switched sides, helping them to capture Kabuto and then scouring the base in order to reunite Sasuke with Naruto. He succeeded, but was attacked by Sasuke, the magnitude of which drew the rest of Team Yamato to their location.

Together again, Naruto and Sakura tried to convince Sasuke to come home. Still determined to gain power, he refused, prompting the team to use force. Their efforts were unsuccessful, and Naruto, in his inability to compete with Sasuke's growth, struggled to reject the Nine-Tails. Within his subconscious, he told it that he never wanted its assistance again, but it was not until Sasuke entered Naruto's subconscious that the Nine-Tails gave up on spreading its influence. In the real world, Sasuke tried to finish off his former, defeated teammates. He was stopped by Orochimaru, however, and they retreated, leaving Team Yamato to return home.

Fire Temple arc
In the anime, Team Yamato was sent on a mission to the Fire Temple. There they met Sora, a young monk who openly disliked Naruto. Despite this, Sora was added to their team to help investigate the grave-robbing of a number of former Twelve Guardian Ninja. Soon after the investigation began, Naruto noticed that the other monks treated Sora much as the villagers of Konoha used to treat him: as an outcast sentenced to loneliness. Naruto asked him about this, but Sora only replied that he didn't blame them.

Upon finding the grave robbers, Naruto was forced into battle with Fuka, a woman that kept trying to kiss Naruto. Through the use of shadow clones, he was able to escape her advances, only to find out that she was a master of all five types of elemental jutsu. Soon afterwards, she managed to kiss him, an act that sucked all the chakra from his body. Once his normal chakra was gone, however, she began sucking out the Nine-Tails' chakra, a force she couldn't handle, and was promptly overwhelmed by. She retreated with her team, and Team Yamato returned to Konoha, with Sora as a temporary substitute for Sai.

Naruto continued to try and befriend Sora, only for his and the efforts of others in Konoha being turned away. When later following Sora, Naruto found him to be trying to kill Asuma and Tsunade. After stopping him, Naruto asked why Sora was being so hostile. He discovered that Asuma had killed Sora's father. Asuma soon arrived to try and explain, but Sora ran off. Naruto once again followed him, but was stopped by Fuka. Forced into battle with her again, Naruto attacked, only to find that she was apparently regenerating from her injuries. Upon noticing that she had stopped using certain elements, Naruto realized that Fuka somehow had multiple bodies, and that each had its own affinity which she could switch between. Coming to the conclusion that her soul resided in her hair, Naruto destroyed all of Fuka's bodies before destroying her hair too, allowing him to follow Sora uninhibited.

When he arrived back in Konoha, Naruto discovered that not only was Sora's father still alive, but that he was behind the various grave-robbings. The more pressing matter, however, was that he had. years earlier, sealed some of the excess chakra, left behind during the Nine-Tails' attack, into Sora, and sought to use its power to destroy Konoha. As Sora lost control of the Nine-Tails' chakra within him, Naruto also struggled to control the Nine-Tails' attempt to create a four-tailed form. He was able to maintain his senses, however, and forced the Nine-Tails' influence to recede, and was able to get through to Sora to help him return to normal as well. The Nine-Tails' chakra was expelled from Sora's body and, finally free, he said goodbye to Naruto before setting out to explore the world.

Hidan and Kakuzu arc
Kakashi, hoping to make Naruto better prepared for his next encounter with Sasuke, trained him to create a new wind-based jutsu. In the anime, this training began before, and continued throughout, the Fire Temple arc, with Naruto seeking assistance from Asuma and Sora, two other wind chakra users. Kakashi had Naruto train with shadow clones to master wind manipulation in only a fraction of the time. When he did this, Kakashi left him with the task of combining what he had learned with the Rasengan. He explained that infusing one's chakra nature with the Rasengan was what Minato had intended to do when he created the Rasengan, but had not been able to do so before he died. Kakashi believed Naruto would prove successful where his father could not, inspiring Naruto to do his best.

While he struggled to create his new Rasengan, the rest of Konoha mobilized to deal with the Akatsuki members, Hidan and Kakuzu. When the two managed to kill Asuma, Kakashi left Yamato in charge of overseeing Naruto's training so that he could help Team 10 avenge Asuma. Once he achieved a usable jutsu, Naruto and Team Yamato went to provide assistance, arriving in time to save Kakashi and Team 10 from Kakuzu. Naruto engaged Kakuzu by himself with his Wind Release: Rasenshuriken, created with the help of shadow clones. Once striking Kakuzu with the attack, two of his hearts were destroyed, and his final heart was left on the brink of failure. Tired out by the ordeal, Naruto's injuries were healed while Kakashi finished off Kakuzu.

Upon retuning to Konoha, Naruto was forbidden by Tsunade to use the Rasenshuriken again. While it was devastating to his opponents, it was equally devastating to the arms he used it with, endangering him and his hopes of remaining a ninja. Naruto said that he realised this, but claimed he understood his own body better than anyone else.

Three-Tails Arrival arc
In the anime, while still recovering from over-using his Rasenshuriken, Jiraiya appeared to congratulate his student's latest successes: defeating one of the Akatsuki members and completing Minato's jutsu. Jiraiya offered to take Naruto on another journey to train, which Naruto quickly agreed to. In truth, Jiraiya's main reason for taking Naruto from Konoha again was so he would not join Kakashi and Team 8 on their mission to find Orochimaru's latest hideout. For their training, they went to a neighboring town to teach Naruto how to use collaboration jutsu with toads. Gamariki was initially summoned to help in this endeavor, but when Naruto proved unable to work with him, Gamakichi and Gamatatsu were summoned instead.

Later, while resting at a hot springs, Naruto met a young boy named Yūkimaru. They talked for a short time about bonds, which made Yūkimaru happy. When Yūkimaru left, Naruto resumed his training, and started having success performing synchronized jutsu with Gamakichi and Gamatatsu. Jiraiya was soon called away, so they returned to Konoha, where Naruto taught Gamatatsu how to perform water-based jutsu. Soon afterwards, he met up with Sai, who let slip that the rest of the team was about to provide back-up for Kakashi in his search for Orochimaru. Determined to help, since he might meet Sasuke, Naruto convinced Tsunade to let him go too.

While searching for Team 8, Naruto ran into Yūkimaru again, and offered him a chance to join him back at Konoha, in response to which Yūkimaru quickly disappeared. As Naruto and his team found themselves halted by Guren's crystal barrier, Naruto summoned Gamakichi and Gamatatsu for help. They then used the Wind Release: Toad Gun to break through, and on the opposite side found Team 8. When they noticed that Hinata had been captured, they helped rescue her, before retreating. The combined teams followed Guren to a lake, where Naruto was sent ahead to scout the area. He found Guren and her forces (amongst them being Yūkimaru) with the Three-Tailed Giant Turtle, who created a tidal wave that drove them all back to shore.

While the team decided what to do with the Three-Tails, Naruto went off to confront Yūkimaru. He found Guren instead, and they argued over what would really make Yūkimaru happy. Yūkimaru soon appeared as well, but after saying that he appreciated Naruto's efforts but would rather stay with Guren, left with her. Before he could go after them, he was called back to help with the tailed beast, his goal being to prevent Guren and her forces from interfering with its sealing. To his delight, Kakashi also tasked him with safely retrieving Yūkimaru.

Despite their best efforts, Guren was able to stop the sealing. Yūkimaru used this as an opportunity to try and control the beast, prompting both Naruto and Guren to come to his aid. In the process, they were both eaten by the Three-Tails, giving them an opportunity to talk and find out they both had Yūkimaru's best interests in mind. Setting their differences aside, they teamed up to escape. Outside, they found Rinji trying to drug Yūkimaru. After Naruto and Guren managed to stop Rinji, they discovered that it was really Kabuto in disguise. Kabuto revealed that Rinji had become part of his corpse collection long ago, and was reanimated through his medical ninjutsu.

While Naruto faced off against Kabuto, Rinji was resummoned and sent up against Guren, whose bat-oriented jutsu turned out to be a perfect counter to Guren's crystal jutsu. After Guren sacrificed herself to defeat Rinji, Yūkimaru went into such an emotional outburst that it gave the Three-Tails the power to break free from the sealing barrier. Afterwards, with the Three-Tails escaping and Kabuto disappearing, Naruto went to aid the weakened Yūkimaru. Later, Shizune was able to heal Yūkimaru, but explained his chakra network was too damaged to ever control the Three-Tails again.

The following morning, after Tsunade had ordered the team to return to Konoha, Naruto discovered that Yūkimaru had vanished. After discovering that Yūkimaru had left his crystal from Guren behind, he realized that Guren was still alive, and with Yūkimaru. Knowing that the two would be fine, he decided not to pursue them. While failing to seal the Three-Tails, the successful saving of Yūkimaru inspired Naruto more than ever to bring Sasuke back to his true home, with his friends in Konoha.

Hunt for Itachi arc
After news of Orochimaru's defeat at the hands of Sasuke, Team Kakashi decided to make another attempt to find him. Knowing that Sasuke was going after his older brother, Itachi, they teamed up with the members of Team 8 to find either of the Uchiha brothers. They scoured the landscape, and eventually encountered Kabuto, who had absorbed some of Orochimaru's remains into his body. As thanks to Naruto, his efforts to overcome the Nine-Tails being similar to his efforts to overcome Orochimaru, Kabuto gave him a book containing some information on Akatsuki before he could be captured.

After regrouping and picking up on Sasuke's trail, Naruto used a number of shadow clones to search the area faster. When one of his clones neared what he thought was Sasuke's location, he found Itachi there instead. Itachi repelled all of Naruto's attempts to attack him, insisting that he only wanted to talk. He trapped Naruto in a genjutsu and, as was later revealed, questioned Naruto on his dedication to Sasuke and to Konoha. When Naruto insisted that he would protect both at any cost, Itachi gave Naruto some of his power in case he ever needed it. Itachi left, and Naruto continued his search, eventually finding Sasuke.

When the real Naruto and the rest of the team moved to intercept him, they were stopped by Tobi. Despite their efforts to quickly dispose of Tobi, none of their attacks worked, and it was only after word reached them that Sasuke had killed Itachi that they were allowed to continue. Tobi, however, reached Sasuke first. Having lost the trail, the Konoha ninja were forced to give up the search.

Senjutsu Training arc
When he returned to Konoha, Naruto learned that Jiraiya had died in his battle with the leader of Akatsuki, Pain. Grief stricken, Naruto blamed Tsunade for his death, and departed. He spent the rest of the day mourning the loss of his teacher, musing over the fact he had wanted Jiraiya to be there when he became Hokage. After being comforted by Iruka, Naruto helped to decipher Jiraiya's dying message with Shikamaru. When the code was broken, Naruto decided to go to train with the toads to learn senjutsu, knowing that Pain was coming for him and deciding to make the most of the time Jiraiya had bought for him.

To learn senjutsu, Naruto trained to harmonize with nature, a process he sped up by using a limited amount of shadow clones. He rapidly progressed through the introductory stages and attained a perfect Sage Mode, something Jiraiya had never been able to do. Because harmonizing with nature cannot be done in the midst of battle, Fukasaku tried to fuse with Naruto so that he could gather natural energy for Naruto's use. When the Nine-Tails rejected all of Fukasaku's attempts at fusion, Naruto was forced to find an alternative, and used shadow clones in a desperate attempt to learn how to gather natural energy while moving. News of Pain's attack on Konoha soon reached them, and they mobilized for battle.

Invasion of Pain arc
Naruto (in Sage Mode), Fukasaku, Gamaken, Gamahiro, Gamabunta, and Gamakichi were summoned to the centre of Konoha. Naruto did not immediately recognize the crater he had been summoned to, before noticing the Hokage Monument in the distance. Realizing that Pain had destroyed the village, an infuriated Naruto stopped Pain's Asura path from attacking Tsunade with his Rasengan. The body was destroyed, and Naruto sent Tsunade away, instructing her to make sure none of the other villagers intervened in the battle.

Pain's Animal path summoned a number of animals to attack Naruto, who used the increased strength granted to him by Sage Mode to bat them aside to his toad allies. While they dealt with the summons, Naruto disposed of the Preta path, before preparing the fruits of his senjutsu training: a perfected Rasenshuriken. He hurled the attack at Pain's remaining bodies, and it expanded when it neared them, disintegrating the Human path. Running low on chakra because of the attack, Naruto had Gamabunta trap the Animal path in his mouth, where Naruto was able to defeat it with his Rasenrengan without interference from the other bodies.

Having run out of natural energy and thus having exited Sage Mode, Naruto had Fukasaku summon one of his shadow clones from Myōbokuzan. As a workaround for his inability to have a constant supply of natural energy, he had had some of his shadow clones gather it for him. Revitalized, Naruto attacked with another Rasenshuriken, only for the Preta path to appear and absorb the attack. Realizing that the Naraka path must have restored it, Naruto focused his efforts on getting rid of it. He distracted the Deva path with a smokescreen, and landed another Rasenrengan on the Naraka path.

Though he had defeated four of Pain's six bodies, Naruto was captured through a combination of efforts from the Deva and Preta paths. The Preta path absorbed his chakra to make sure he was no longer a threat but, being unable to handle natural energy, turned into stone, allowing Naruto to free himself. The Deva path captured Naruto again, and killed Fukasaku when he tried to come to help. While immobilizing Naruto, the Deva path told Naruto of his plans for world peace. When Naruto disagreed with his views, Jiraiya's death being a byproduct of that peace, the Deva path asked Naruto for a better solution.

Before he could answer, Hinata came to Naruto's aid. She confessed her love for Naruto (greatly shocking him) and engaged Pain in battle in a futile effort to save him. When she was apparently killed, an enraged Naruto exploded into his six-tailed transformation. His necklace reacted in an effort to quell the transformation, but the Nine-Tails destroyed it and attacked Pain. Unable to deal with this new threat, the Deva path retreated to a location where it could use Chibaku Tensei. The animalistic Naruto was drawn into it and restrained, prompting Naruto to give his heart to the Nine-Tails in a desperate attempt to gain the power needed to stop Pain, releasing the eight-tailed transformation. Before he could completely release the Nine-Tails, however, Minato appeared in Naruto's subconscious to stop him.

Minato revealed that he had designed the seal of the Nine-Tails to allow an imprint of himself to appear if ever the seal was about to break, a failsafe meant to protect his son. Picking up on this, Naruto realized that the Fourth Hokage was his father, and was overjoyed to finally know who one of his parents was. His time being short, Minato revealed that he had sealed the Nine-Tails into his own son because he thought Naruto would someday find use for it in finally stopping Madara Uchiha. They also discussed the concept of peace, and Minato revealed that hatred gave rise to Pain, and that ninjas must find a way to end the hatred. While Naruto doubted that he could do it, Minato replied that he believed Naruto would be able to find the answer, and restored the Nine-Tails' seal before disappearing.

Outside, Naruto emerged from the Chibaku Tensei, the Nine-Tails' influence gone and Sage Mode having returned. He clashed one final time with the Deva path, using the five-second gap in the time between its attacks to his advantage. Although his Rasenshuriken missed, he was able to muster enough shadow clones to resist the path's gravitational abilities. In the brief interlude between attacks, Naruto struck it with the Rasengan, defeating the last of Pain's bodies. The battle won, Naruto sought out Nagato, Pain's base mind, to finally answer his earlier question about peace. Naruto admitted to his raw anger and hatred towards Nagato, but he held his ground, and asked Nagato how he had turned out this way after being Jiraiya's student. After hearing Nagato's past, Naruto agreed that, on some points, Nagato was right, but he shocked both Nagato and Konan after he declared that, despite hating them, he would not kill them, simply for his desire to "break the cycle of hatred", and his answer was to believe in Jiraiya's idea of peace. Amazed by Naruto's determination to his answer, Nagato said that he would believe in Naruto, and revived all the people Nagato had killed in Konoha, at the cost of Nagato's own life. With this, Naruto helped Konan retrieve Nagato and Yahiko's bodies for burial in Amegakure. After confirming that she had quit Akatsuki and taken leadership of Amegakure, she left Naruto a bouquet of paper flowers for him, symbolizing their newly found alliance.

Five Kage Summit arc
Kakashi fetched the weakened Naruto and brought him back to Konoha. There, Naruto was greeted by all of the Konohagakure villagers and shinobi, prompting him to think back to his original reason to become Hokage: to be acknowledged by everyone in the village. Some of the villagers are also shown saying that Naruto's heroism makes him worthy of becoming Hokage.

Later, while wandering the village, he runs into Tazuna and a grown-up Inari, who have come to help rebuild Konoha as carpenters. While catching up, they ask him about Sasuke. Naruto replies that they had "had a fight" that made Sasuke leave, but that he would be bringing him back soon. Soon afterwards, Naruto learns that Danzo has been appointed as Hokage to replace the comatose Tsunade. As his first act, Danzo has ordered Sasuke eliminated as a missing-nin. Naruto tries to go to object to this but is stopped by Kakashi, who points out that doing so would give Danzo a reason to put him in jail. Instead, he questions Sai about Danzo, but is unable to learn anything useful.

Naruto, Sai, and Sakura are confronted by the Kumogakure ninja, Karui and Omoi. Karui informs them that Sasuke has joined Akatsuki and captured Killer Bee, something that has created some animosity between Kumogakure and Konoha. Naruto reassures them that there is still time to save Killer Bee and offers to tell them about Akatsuki; however, when they ask about Sasuke, Naruto, thinking back to his conversation with Pain, is unable to sell out Sasuke, knowing that that will only create a new cycle of revenge. As compensation, Naruto offers to let Karui beat him up, which she gladly accepts. Sai intervenes, and the Kumogakure ninja leave.

As Naruto recovers from his beating, he tells Kakashi and Yamato that he must meet the five Kage to inform them of Madara Uchiha, as well as convince the Raikage to forgive Sasuke. Kakashi and Yamato agree to be Naruto's escorts to the Kage Summit. Yamato places a tracker on Karui and her team, allowing Naruto to follow them to the Land of Iron. Due to his injuries suffered from Karui's assault Naruto is seen wearing a bandage across his right eye as he sets out for the Kage Summit. Eventually, Naruto, Kakashi, and Yamato catch up to the Raikage, stopping them before they head off to the summit.

Naruto then begs for the Raikage to forgive Sasuke of his crimes, a request which the Raikage refuses to listen to. At this point, Naruto prostrates himself and bows before the Raikage, begging to change his mind, as chasing Sasuke for revenge would not only lead to war between Konoha and Kumo, but also twist him into what Sasuke became. The Raikage promptly shouts at Naruto, putting down his notion of friendship and tells him that the only thing ninja respect are power and strength. The Raikage then heads off to the summit as Kakashi tells Naruto to stand up.

As the Summit of the Five Kages progressed, Naruto lay saddened and confused at what appeared to be an inn somewhere in the Land of Iron, wondering if Sasuke's hatred had indeed turned him into a common criminal. His thoughts are interrupted by the sudden appearance of Madara Uchiha, who casually requests an audience with him. A startled Naruto greets him with a Rasengan but is unsuccessful in harming him. Kakashi and Yamato intervene, quickly restraining Madara. Unfazed, Madara admits that he is curious about Naruto and queries about how he managed to turn Nagato into a collaborator. An angry Naruto quickly dismisses the relevance of his question and demands to know what he plans to do with Sasuke. Madara agrees to elaborate on Sasuke's descent into darkness.

Abilities
At the start of the series, one of the only jutsu Naruto could do without fail was his own original Transformation Technique, called the Sexy Technique; a creative but almost completely useless diversionary jutsu, used simply to shock his instructors. Naruto was also able to use simple E-rank abilities, like the Cloak of Invisibility Technique and Body Replacement Technique. Although Naruto had trouble with the Clone Technique at the start of the series, he quickly learned how to use Jonin-level techniques, like the Shadow Clone Technique and its larger-scale version.

While under the tutelage of Jiraiya, Naruto's abilities have continued to improve; his prowess in ninjutsu and taijutsu have grown greatly, and he had also been taught some limited skill at dispelling genjutsu. But, undisputedley, the most valuable assets that Naruto has gained in his training with Jiraiya are an increased range of battle smarts and more knowledge of the basics of a shinobi, which he lacked during Part I. This, along with the skills and abilities Naruto has gained, makes him a much more complete ninja. However, during Part II, Naruto has regularly proven himself a match against the S-Class members of Akatsuki, demonstrating Kage-level fighting prowess.

Shadow Clone Technique
Naruto's first signature jutsu, the Shadow Clone Technique takes advantage of the massive chakra reserve Naruto possesses due to him being the jinchūriki of the Nine-Tails. Naruto is able to create upwards to two thousand clones, and able to have a decent amount of chakra in each of them. Because of this, Naruto can use his shadow clones for almost anything, from straight combat to training.

In the beginning, Naruto would create a multitude of clones to overwhelm his opponents. Other times however, he would employ the use of the Transformation Technique to change the appearance of this clones to catch his target off guard. By Part II, Naruto learned that whatever his shadow clones learn, he, the main mind, will also learn. By using this, he is able to learn something that would take years in days. Naruto also learned that he could use the shadow clones to determine his opponents' abilities, to determine how many clones he will really need to defeat them instead of wasting chakra on thousands of clones.

Toad Summon Skills
Naruto was first taught how to use the Summoning Technique by Jiraiya. After allowing Naruto to sign the Summoning Contract with the toads of Myōbokuzan, Jiraiya took Naruto through the execution of the technique in order to provide Naruto with allies in future battles. Additionally, Jiraiya's other motivation to teaching Naruto how to summon, was in order to help Naruto to realize, and take advantage of, the Nine-Tails' chakra reserves.

The type of toads that Naruto can summon at any time is proportional to his chakra and skill, as when he first started out he could only summon tadpoles. At first, Naruto would have a hard time getting any specific toad, as he would summon either Gamakichi or Gamatatsu. But when he used the Nine-Tails' chakra, or when he is truly motivated, Naruto was able to summon the toad boss, Gamabunta.

Rasengan
Created by the Fourth Hokage and taught to him by Jiraiya, the Rasengan is Naruto's second and strongest signature jutsu. While the Rasengan is a one handed technique, Naruto required the use of two to form it due to his poor chakra control, thus using a clone to form the "shell" of the sphere. Despite this, Naruto has used the Rasengan effectively in almost every one of his fights after mastering it. The Rasengan holds an advantage over its counterpart, the Chidori. The Rasengan only requires chakra control to form, while the Chidori uses so much chakra that it can only be used a few times a day. Naruto mastered the Rasengan to a degree that he can do it almost instantaneously.

The Rasengan, like the Clone Technique, would be the base of several original jutsu created by Naruto, such as the Great Ball Rasengan, a larger version of the Rasengan, and after his wind training created the Wind Release: Rasengan and Wind Release: Rasenshuriken, and after his senjutsu training, the Sage Art: Great Ball Rasengan and Sage Technique: Rasenrengan.

Due to the unique nature of the Rasengan in Naruto movies, Naruto creates a new type of Rasengan, often facilitated by a character in the movie, or a unique property present in the movie.

Wind Release
After failing to bring Sasuke back to Konoha, Naruto went through elemental training where he discovered that he had an affinity to wind, which by incorporating into the Rasengan, which was originally intended to be combined with a nature element, would greatly increase his power and his chances. The wind nature compliments a fighter like Naruto, as the wind nature is a good match with short ranged fighter. By focusing his wind chakra, Naruto can go as far as cut things with only his chakra.

Naruto had learned nature transformations to upgrade his Rasengan, which he achieved with the Wind Release: Rasengan and the Rasenshuriken, combining both shape and nature manipulation originally deemed impossible without natural talent or instinct. The Rasenshuriken was capable of slicing into the victim and cutting them at a cellular level faster than a Sharingan can see it. It however caused similar damage to himself as it is still a handheld jutsu, despite it's name. After his sage training, he could throw the Rasenshuriken and expand it, increasing its power and attack radius.

Senjutsu
After Jiraiya's death at the hands of Pain, Naruto began training with Fukasaku in Myōbokuzan to learn senjutsu and how to enter Sage Mode. In order to achieve this, Naruto had to learn to sense and control the natural energy around him. Once mastered, Naruto was able to perfect the Rasenshuriken, so that he could throw it, and learn Frog Kata, the taijutsu style that uses the natural energy around the user to enhance the range and the potency of their attacks.

However, Naruto had one fatal flaw in his senjutsu training. To mold senjusu chakra, the user must remain absolutely still. Something one can not do while in combat, and because of the Nine-Tails, Shima and Fukasaku are unable to fuse with Naruto to mold it for him. To counter this, Naruto has to leave two shadow clones in a safe place to mold the senjutsu chakra for him. Once he depletes his current amount of senjutsu chakra, he would dispel one of the clones and gather it's senjutsu chakra to reenter Sage Mode.

Creation and Conception
When creating Naruto, Masashi Kishimoto incorporated into the character a number of traits he felt made an ideal hero: a straightforward way of thinking, a mischievous side, and many of the attributes possessed by Son Goku from the Dragon Ball franchise. He also made sure to keep Naruto "simple and stupid", since he does not like smart characters. Naruto himself is not modelled after anyone in particular, being conceived as childlike, with something of a dark side as a result of his harsh past. Despite this, he is always positive, making him unique in Kishimoto's eyes.

Naruto's wardrobe is based on clothing Kishimoto wore when he was younger; according to Kishimoto, using a pre-existing design would not have made Naruto unique, whereas something original would have made him stand out too much. The orange coloring of his costume is used to make Naruto "pop", with blues often being used to complement the orange. Because Naruto is associated with spirals, swirl patterns are incorporated into his costume. Initial illustrations of Naruto had him wearing boots, but Kishimoto substituted these for sandals, because he likes drawing toes. The goggles that Naruto used to wear were also replaced with a forehead protector, because the goggles themselves were too time-consuming to draw. Kishimoto said that he felt glad that his character had blond hair and blue eyes. The editor of Shonen Jump in the United States added that he implied that the traits may have led the character to appeal to a Western audience. Kishimoto said that he most identifies with Naruto out of all of the Naruto characters.

In the Japanese versions of Naruto, Naruto often ends his sentences with the addendum "-ttebayo" (which gives a similar effect to ending a sentence with "you know?"). Kishimoto wanted to give Naruto a childlike catchphrase, and "dattebayo" came to mind. It complements Naruto's character, and serves as a verbal tic that shows him to be something of a brat. Throughout the beginning of the English, the dub replaced "dattebayo" and "-ttebayo" with the phrase "believe it!" to mirror the effect, as well as to match the character's lip movements.

Trivia

 * Spirals and swirl patterns are a recurring theme in Naruto, especially in relation to Naruto. "Naruto" can mean "maelstrom", and is also the name for a sliced stick of kamaboko with a pink whirlpool design in the middle that is used as a topping for ramen, which is Naruto's favorite food. The surname "Uzumaki" is a pun on, because it refers to a three-dimensional spiral, like a whirlpool or vortex. "Uzumaki" can also mean "whirlpool", in reference to the , named after the city of Naruto.

According to the latest character poll, which adds up all the votes from the first six polls, Naruto took second place.
 * In the manga, Naruto has a habit of flipping people off when excited or angry. This is shown in the Chunin Exam arc of the manga, when Naruto flipped off the other teams to "pysch himself up" and when Jiraiya is peeking in the hot springs and refuses to train Naruto.
 * The coat Naruto wore upon returning to Konoha to face Pain is nearly identical to the one his father, Minato Namikaze, wore as the Fourth Hokage. The only difference is the color; Naruto's coat is red with black flames, while Minato's was white with red flames.

Quotes

 * "And my dream is to be the greatest Hokage! That way, people will stop disrespecting me and start treating me like I'm somebody. Someone important!"
 * "I never give up, and I never go back on my word! That's my Nindō: my ninja way!"

I also know that this is a very risky path. Even so, I want to take this risk alone. If I can't beat this, I'll never be able to grow up. So please... please... don't take this path away from me."
 * (To Itachi about Sasuke) "Because he's like a brother to me ... and I'm a better brother than you ever were!"
