Naruto Uzumaki (うずまきナルト, Uzumaki Naruto) is the title character and main protagonist of Naruto. He is a genin from Konohagakure, a member of Team Kakashi, and the third jinchūriki of the Nine-Tailed Demon Fox.
Naruto was born as the son of the Fourth Hokage, Minato Namikaze, and the Nine-Tails' second jinchūriki, Kushina Uzumaki. Naruto's parents had named him after the main character of Jiraiya's first book, making the Sannin his godfather.
Prior to Naruto's birth, his parents knew that the seal that kept the Nine-Tails within Kushina would be in danger of breaking during childbirth. To prevent that threat Kushina was taken a short distance outside of the village to give birth in secret, with Biwako Sarutobi and Taji as her midwives, a few ANBU as security, and with Minato keeping the seal in place. Immediately after Kushina gave birth, Madara Uchiha appeared and took Naruto hostage, demanding Minato to step away from Kushina or he would kill the newborn child. Madara then used a clever diversion that forced Minato to transport the baby to a safer location, allowing him to escape with Kushina. By the time Minato could intervene, Madara had already succeeded in releasing the Nine-Tails.
Fortunately, Kushina (who survived the extraction thanks to her strong vitality) was saved by Minato and brought to Naruto, leaving the weakened mother to care for the sleeping Naruto while Minato went to combat Madara. To save the village, Minato sacrificed his life to seal the Nine-Tails within Naruto, believing that his son would someday have need of the demon's power to defeat Madara's threat once and for all. Suddenly orphaned, Naruto was left to grow up knowing nothing of his parents, receiving only his mother's last name since the Third Hokage felt that it was best that nobody knew that 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 defeat the Nine-Tails. However, only a few of the villagers honoured his request, while most instead resented 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 truth about Naruto, hoping that their children would not resent him as they did. The children, however, followed their parents' lead, despite not knowing why. Apart from the Third Hokage, Iruka Umino was the only one who acted as a surrogate family to the young Naruto.
As stated by Jiraiya, Naruto bears a striking resemblance to his father, possessing Minato's blue eyes and spiky, blond hair. From his mother, Naruto inherited the shape of both his eyes and face. However, Naruto's greatest physical characteristic is his whisker marks, passed on from the demon imprisoned within his mother at the time of his birth. A trait regularly mentioned, that easily angered him, was his short stature for his age. After the time skip, he had a significant growth spurt that was noticeable to all.
In Part I, Naruto's outfit consisted of a orange jumpsuit with blue on the upper shoulders area as well as up and down the front, a white swirl with a tassel on the left side, a red swirl on the back, a big white collar, orange pants, blue sandals, and a blue forehead protector that was given to him by Iruka after he graduated from the Ninja Academy. In Part II, Naruto's outfit undergoes modification after being worn to shreds during his training with Jiraiya. The outfit retains the orange colour as well as the white (without the tassel) and red swirls, but the jacket is much more form fitting with the blue parts changed to black and the colour extending from the upper shoulders area to the sleeves. The forehead protector has also changed with Naruto moving the metal portion to a new longer black bandanna and he wears black sandals instead of blue. During his battle with Pain, Naruto briefly sported a red coat that combined his master and father's before him with a black flaming design at the bottom as well as a large summoning scroll on his back.
After Jiraiya's death at the hands of Pain, Naruto began training with Fukasaku in Mount Myōboku 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, a taijutsu style that uses the natural energy around the user to enhance the range and the potency of their attacks. In Sage Mode, Naruto's overall physical abilities are dramatically enhanced to the point where he could throw entities much larger than himself with little to no effort, including the Animal Path's Giant Rhino and the Nine-Tails. His speed increases to a point where he was able to intercept a charging Asura Path, which had been using its chakra boots to attack Tsunade, create a Rasengan and slam it down before it could even react, showing him covering considerable distance in a short amount of time. Also while in Sage Mode, Naruto gains a sensory ability to detect other people's chakra from long distances. His sensing skill in Sage Mode is so great he could pick out an individual's chakra out of an entire village worth, and note that it wasn't there. His sensing skills have increased to the point where he could sense several individuals battling the White Zetsu Army and resurrected ninjas from hundreds of miles away, even pinpointing Sakura Haruno healing a person. However, Naruto had two flaws in his senjutsu training: To mould natural energy, the user must remain absolutely still, something one cannot do while in combat; and because of the Nine-Tails, Shima and Fukasaku were unable to fuse with Naruto to mould it for him. To counter this, Naruto had to leave two shadow clones in a safe place to mould the natural energy for him. Once he depleted his current amount of senjutsu chakra, he would dispel one of the clones and use the natural energy it had gathered to re-enter Sage Mode. However, this method limits the maximum number of shadow clones that Naruto can create to five. Any more would interfere with the focus of the clones' gathering natural energy. However, this limit in shadow clones ceases should Naruto decide to go all out during a fight and forget having any clones store natural energy for him.Also, Naruto had been training to extend the time he could remain in Sage Mode. His skill with Sage Mode has increased greatly where he only needs a couple moments to enter it. During his battle with the Nine-Tails within his subconscious, Naruto and his large group of shadow clones entered Sage Mode (though it appeared that his "physical self" was able to enter Sage Mode in his meditative state, then his "mental self" reflected the act as well as all of his shadow clones). This is possible a reverse on how Naruto got past his original five minute limit by having a clone transfer the already balanced senjutsu chakra to him.
