Hinata is timid, soft-spoken, thoughtful, polite and very shy, often using appropriate name suffixes. She is kind, a trait that Neji used to consider a flaw, and dislikes competing and fighting. Possibly as a result of her father's contempt for her, Hinata lacks self-confidence, but is very hard working. She is also incredibly empathetic, and, because of her upbringing, is one of the few characters who identifies with Naruto's painful childhood and desire to be acknowledged. Generally, Hinata opts to think carefully before acting, and when she does manage to muster enough self-confidence, she can be surprisingly competent. These episodes of confidence typically occur when around Naruto or for Naruto's benefit. She becomes more open about her opinion as Part I progresses and, by Part II, Hinata is more confident overall and demonstrates a willingness on occasion to take decisive action, unlike before.
Like her team-mates, she is a skilled tracker and can use her Byakugan to see over long distances as well as even the smallest of objects amongst other things. Although he deemed her a failure in Part I, during the Fourth Shinobi World War Hiashi considered her strong enough to protect her cousin, Neji now as much as he protects her.
Hinata with her Byakugan activated.Added by Cerez365As a member of the Hyūga clan, Hinata possesses the Byakugan, an ocular kekkei genkai which grants her x-ray vision, nearly 360° vision (the Byakugan has a small blind spot at the nape of the neck), and the ability to see the chakra pathway system. Hinata can focus her Byakugan's sight to drastically increase its range in one direction, up to 10 kilometres. During the Search for the Bikōchū Arc, she was able to use her Byakugan to magnify and zoom, effectively seeing every small insect in the area. Using her Byakugan in a similar fashion, Hinata even accurately fired chakra needles at bees. In Part II, during her fight against Guren, Hinata demonstrates her mastery of her kekkei genkai; Hinata's Byakugan was at first overcome by Guren's crystal labyrinth, which refracted light to produce many duplicate images of herself. However, forcing herself to focus on her target allowed the Byakugan to function just enough for her to accurately see Guren's real chakra network and not the reflections. It was confirmed by Kakashi that Hinata can use her Byakugan to see through genjutsu, as he requested her to do so when they fought Tobi.
As a member of the Hyūga clan, Hinata specialises in close-range, taijutsu combat. Her fighting style is the signature style of her clan, the Gentle Fist, which takes advantage of the Byakugan's ability to see opponent's chakra pathway system. It also allows her to cause severe internal trauma with minimal external force as it relies on surgical injection of chakra into an opponent's chakra network to cause damage. However, when Hinata is first introduced, she is considered weak by Hiashi Hyūga's standards, being neither as strong nor as fast as Neji or her sister.
 In Part II, Hinata improved her taijutsu skills immensely and displays now a large variety of her clan's techniques. In the anime's Three-Tails Arc, Hinata performed the Eight Trigrams Thirty-Two Palms, a minor version of the Eight Trigrams Sixty-Four Palms, which she claims to had been working on during the time-skip, showing that her Byakugan can even see the tenketsu now. Hinata has also continued to develop her natural flexibility. This was shown while she was battling Nurari in the anime when she was able to dodge most of his attacks, despite the enemy's elastic body. When later fighting Pain in the anime, her attacks were strong enough to snap Pain's Chakra Disruption Blades that were restraining Naruto. In that circumstance she also displays the Gentle Step Twin Lion Fists technique, which much wasn't seen of in the manga but in the anime, she was able to strike Pain with it. She can also collaborate with Neji, using Eight Trigrams Empty Wall Palm, which is a variation of the Eight Trigrams Empty Palm.
After the Chūnin Exams, Hinata trained to become stronger, developing in a way which took advantage of her excellent chakra control. The results of this training are shown during the anime's Search for the Bikōchū Arc; she is first seen training beside a waterfall, where she forms an orb of water around herself. She is later shown forming chakra needles that she uses to attack a swarm of bees. Finally, toward the conclusion of the arc, Hinata revealed an original technique, Protection of the Eight Trigrams Sixty-Four Palms. With it, she emits streams of chakra from her palms to create extremely sharp blades, which can be used to hit any target in her field of vision. Due to her excellent chakra control and her natural flexibility, Hinata is able to freely manipulate the size and strength of the chakra blades, effectively allowing her to use this technique to attack and defend simultaneously.
In Part II of the anime, Hinata's chakra control has advanced greatly as seen in the Three-Tails Arc, where, despite not being a medical-nin her chakra control was mentioned as being at least on par with one, as she was selected to perform the Four-Corner Sealing Barrier along with Sakura, Ino, and Shizune. Ino, although trained as a medical-nin, had difficulty maintaining and controlling her chakra to sustain the seal, unlike Hinata, who managed with relative ease.
Hinata has a long-standing admiration, which has now developed into unquestionable and undying love for Naruto. From the start, Hinata's affection for Naruto was really obvious to almost every character except Naruto himself, who remained oblivious to her feelings. In fact, Naruto did find it awkward to be with Hinata at times since she was unable to properly articulate herself in his presence. Despite this, Naruto has shown to have some form of concern for her at times, as the two have been shown to get along quite well with one another. As the series progresses, Hinata goes to great lengths for Naruto because she fiercely believes in him. Naruto's two-and-a-half-year absence did nothing to diminish her feelings for him, and in fact, she fainted when he first returned. During the invasion of Pain, Hinata finally confessed her love to Naruto and was also willing to die to protect him. This event was actually the first time Hinata had spoken to Naruto without blushing, fear, or awkwardness.
Hinata gets along well with her team-mates. Kiba's actions toward her are often motivated by his concern for her, such as when he urged her to forfeit if she was matched against Neji or Gaara during the Chūnin Exams. Shino possesses a quiet confidence in Hinata, and will make a point of assuring others when they doubt or worry about her. Hinata is also the closest to Team 8's sensei, Kurenai, who is not only interested in Hinata's growth as a ninja but also as a person. She knows Hinata's personal struggles and unlike her demanding father, Kurenai tries her best to coach Hinata in ways in which she knows her pupil will best respond. After Hinata was knocked down for the final time by Neji in the Chūnin Exams, Kurenai silently congratulated her student's resolve and perseverance. By the end of Part I, she also fostered better relations with both her cousin, Neji, and her father and began training with the two of them.
