Hiashi Hyūga

is a shinobi from Konohagakure as well as the current head of the Hyūga clan.

Background
Hiashi was born only seconds before his twin brother Hizashi, making Hiashi the head of the Hyūga clan and Hizashi a member of the branch house, whose only purpose in life would be to protect members of the main house. Years later, when Neji was born, Hizashi became bitter that his son would never be able to reach his full potential like a member of the main house, causing him to be openly resentful of Hiashi and his daughter. Hiashi was also responsible for branding the family's curse seal on Neji's forehead, further straining the relationship between the two brothers. One day during Hinata's training, overwhelmed with resentment and anger, Hizashi gave Hinata a murderous glare, Hiashi sensed the killing intent and activated the curse seal on his younger brother, causing him intense pain. He told Hizashi to leave as he would no longer tolerate incidents like this, telling him to never forget his duties.

During a visit to Konoha by a Head Ninja of Kumogakure, who had come to the village to sign a peace treaty, a young Hinata was kidnapped. Hiashi however saved her, quickly killing her would-be kidnapper, only to discover that it was the Kumogakure ambassador. Kumogakure demanded Hiashi's head in return for the life he had taken, or risk resuming open warfare between the two villages. Konoha, wishing to avoid another conflict, was compelled to comply, but was not willing to fulfil Kumogakure's desire of getting to study the Byakugan. Their father suggested that Hizashi be used as a body double, since his cursed seal would seal off his Byakugan upon his death. Although Hiashi tried to find an alternative to this, Hizashi insisted, saying that he would finally get to choose his own fate (to make up for his wrongdoings against Hiashi), and save his brother's life. Before going to his death, he asked Hiashi to someday tell Neji about why he had made his decision.

Originally, Hiashi had trained Hinata to become the successor of the Hyūga clan. However, Hinata's lack of confidence ultimately led him to decide she was not worthy. He instead turned his attention to his younger daughter, Hanabi Hyūga.

Personality
Hiashi's general personality is very stern and strict, as he assigned both his daughters arduous training, and rarely compliments their performance. This is especially true with Hinata; when she was assigned to Kurenai, he told her that he was unconcerned about the possibility that she would die, saying that the Hyūga clan had no use for a weak successor. In truth, what he felt was weak was not Hinata's talent or potential but her drive to succeed as the successor of the Hyūga clan. As the series progressed and she started to show her true dedication, he began to openly cheer her on. Hiashi was also very strict with his younger brother and nephew, and was willing to use the cursed seal to punish if they disobey. However, he truly cares for them as part of the family and his brother primarily seen in his hesitation to allow him to die to protect the secret of the Byakugan.

After the noble sacrifice of his brother, Hiashi began to change his views with the caste system of his clan. As a result, Hiashi has also shown at times to be lenient and is not as strictly devoted to following the main house's traditions, as seen when he started training Neji in the Hyūga clan's full arts in the hopes to end the growing rift within the clan, despite it being considered a taboo to pass down secret techniques of the main house to members of the branch family.

Appearance
Being an identical twin, Hiashi is a mirror image of his brother Hizashi with the exception of an unmarked forehead. He has long, black hair (sometimes depicted as brown in the anime), and featureless white eyes like all members of his clan. He normally wears very traditional, loose fitting robes with a long-sleeved, brown haori. As part of the Allied Shinobi Forces, he donned the standard uniform of the Konoha shinobi, along with a black forehead protector (bandanna-style in the anime) of the alliance.

Abilities
As the leader of the Hyūga clan, Hiashi is undoubtedly a powerful shinobi. He's a master of the Gentle Fist taijutsu art. He is also knowledgeable in juinjutsu such as the one used by his clan, used to brand members of the Branch House.

Byakugan
As a member of the Hyūga clan, Hiashi possesses the Byakugan: a dōjutsu kekkei genkai which grants him an almost 360° field of vision (with the exception of a small blind spot at the upper thoracic vertebrae), x-ray vision and the ability to see the chakra pathway system. He was also able to use the dōjutsu's extensive visual range to watch as a far off village was destroyed in an instant by the Ten-Tails' Tailed Beast Ball.

Gentle Fist Art
Also, as the head of his clan, he is well-versed in all of his clan's secret techniques. While the full extent of his prowess remains unknown, during Orochimaru's invasion, Hiashi demonstrated tremendous skill by repelling several Oto and Suna ninja with the Eight Trigrams Palms Revolving Heaven technique. He also showed his great skill with the Gentle Fist when he killed the Head Ninja of Kumogakure with a single strike to the chakra pathway system around his heart and left the fight unharmed. When collaborating with his nephew, Neji, they were able to combine the force of their Eight Trigrams Palms Revolving Heaven technique and deflect the Ten-Tails' tail without giving any ground. He can also use the Eight Trigrams Vacuum Wall Palm with such force using his both hands, that he was able to buffet one of the Ten-Tails' tails away by himself. He can also use the Eight Trigrams Vacuum Palm to hit targets seemingly out of his range.

Chūnin Exam Arc
Hiashi made his first début in Kurenai's flashback, when she was watching Hinata's and Neji's match in the preliminary matches of the Chūnin Exams. Hiashi debuted for the first time (in person) with Hanabi, watching Neji's match during the final rounds. He was amazed that Neji had been able to learn the main house's secret techniques by himself, but was disappointed by Neji's resentment of the main house, and his strong belief in fate. After Neji lost to Naruto Uzumaki, and seemed to have found himself at a crossroads in his life from Naruto's words, Hiashi decided to tell him about the circumstances surrounding Hizashi's death. Although Neji did not initially believe him, Hiashi's bowing to him for forgiveness showed him that it was true. In the anime, he also gives Neji a letter written by Hizashi, explaining the circumstances surrounding his death.

Invasion of Konoha Arc
When the invasion that was devised by the Otogakure and the once allied Sunagakure ninja began, Hiashi assisted the other Konoha shinobi in driving the renegade forces out of the village. Surrounded by shinobi, one of whom confidently commented that there was only one opponent and several of them. With his Byakugan activated, Hiashi used the Eight Trigrams Palms Revolving Heaven to defeat them all in one fell swoop. He then told them that the Hyūga were the strongest in Konoha; a fact they would do well to remember.

Sasuke Retrieval Arc
Towards the end of the arc, after the Sasuke Retrieval Team returned to the village and Neji was resuscitated by the medics at the hospital, Hiashi began taking a more active role in Neji's training. They were seen at the Hyūga estate sparring until Hinata brought them tea and Hiashi declared that they should take a break. During this time, the three casually chatted until Kiba Inuzuka, Akamaru, and Shino Aburame arrived on the compound to get Hinata. In the anime, this was moved to the beginning of the Mizuki Strikes Back Arc.

Invasion of Pain Arc
Hiashi was noted to be away with Hanabi during Pain's attack on Konoha. He left Hinata's protection to Kō Hyūga during his absence.

Konoha History Arc
In the anime, it was later revealed that during the Invasion of Konoha a pair of Kumogakure ninja had tried to steal the Byakugan, kidnapping Hinata once again. After hearing about what happened from his father, he and Kō Hyūga set out to rescue Hinata. He arrives just as Neji is about to be struck fatally after trying to save Hinata. Hiashi blocks the attack using the Eight Trigrams Palms Revolving Heaven. Upon realising who he was the ninja attempts to flee, but he uses the Eight Trigrams Vacuum Palm to stop him. When Neji questions him on why he'd leave the battlefield to come after them, Hiashi tells Neji that Hinata is his precious daughter, and Neji, a precious memento of his late brother.

Shinobi World War Arc
When Hiashi returned to Konohagakure, he was assigned to the First Division of the Allied Shinobi Forces under Darui's command. While his division was taking up their post and Akatsuki's army was starting to advance, Hiashi used his Byakugan and saw not only the White Zetsu Army clones, but many revived shinobi mixed in with them as well, including, much to his shock, his brother, as well as Dan and Asuma amongst the reincarnated shinobi.

Hiashi confronted Hizashi who cursed that though the branch family was supposed to protect the main house, he stood before him as an enemy and lamented that this must be his fate for defying the main house while he was alive. Remembering his brother's last words to him before his death, Hiashi stated that there was no such fate and that Neji and Hinata were on the battlefield fighting alongside one another to prove that, not as branch house and main house members, but as two comrades protecting one another. With this, the two brothers began battling. As the battle at the coast concluded, Hiashi stood on Chōji's colossal fist as the latter restrained his brother in his fist.

Ten-Tails Revival Arc
Hiashi along with the rest of the Allied Shinobi Forces later relocated to the battlefield where the jinchūriki were located. Announcing their arrival, Hiashi apologised to his fellow jōnin that they had kept them waiting so long, and then commended Ino for throwing the beast's attack off even though her control of the Ten-Tails was short lived. Hiashi later stood alongside the other members of the Allied Shinobi Forces to face their opposition. As the Alliance's attempt to incapacitate the Ten-Tails proved futile, and the now fully-matured beast emerged from the hole it had been trapped in Hiashi noted that its Tailed Beast Ball destroyed an entire town far away in an instant. He also watched on after he realised that the next blast was headed towards the Alliances' Headquarters.

Instructing Neji to use the Eight Trigrams Palms Revolving Heaven technique along with him as the Ten-Tails attacked once more, Hiashi later told Naruto that then wasn't the time to get distracted. He goes on to tell him that in war there was always the possibility that people might die, but they had to fight on to ensure that everyone didn't die and that he, Neji, and Hinata were going to protect him on the battlefield. Deflecting the subsequent projectiles which rained down on them, Hiashi used the Eight Trigrams Vacuum Wall Palm technique to deflect the beast's tail, which was headed straight for them only to see the beast launch an pinpoint attack at Naruto and Hinata. Afraid that neither Neji nor Hinata would not be able to deflect it in time, Hiashi watched in horror as his nephew used his body as a shield to protect Naruto and Hinata and later passed away, having been heavily injured. As Hiashi watched on, he apologised to his brother for not being able to protect Neji. After Hinata had been enveloped with Kurama's chakra, Hiashi watched on in amazement as she was able to deflect on the the beast's tail with a simple Eight Trigrams Vacuum Palm.

Naruto 5: Blood Prison
During Naruto's flashback to the members of the village when he was gathering natural energy to enter Sage Mode, Hiashi can been seen amongst the villagers.
