Haku

was a villager from the Land of Water, and a member of the Yuki Clan. He later became a Ninja after meeting Zabuza Momochi.

Background
Haku was born in a small, snowy village in the Land of Water, a land that had suffered from war not long before. In this war, different sides battled each other using ninja, some of whom possessed kekkei genkai. After the war ended, memories of the horrific battles still lingered in the minds of the people. Those with kekkei genkai quickly became feared and hated for their abilities, out of concern that their existence would only bring about more war.

Haku's father and mother were simple farmers, and they lived a peaceful life. They loved each other, and were kind to their child. Unfortunately, this all changed one day. Haku's mother was a carrier of a kekkei genkai: Ice Release. She hid this fact from her husband, hoping that the love and peace that was shared in their small family would last forever. One day, Haku discovered the ability to manipulate water. Amazed by this, Haku proudly showed this to his mother, who was horrified by what she saw, and harshly scolded Haku for displaying his ability. Unbeknownst to his mother, Haku's father had seen everything. When Haku's father discovered that his wife and child possessed a kekkei genkai, he assembled a small mob of villagers, and killed his wife. He would have done the same to Haku, but before he could, Haku used his Ice Release to create several large, sharpened pillars of ice to kill his father and the rest of the mob.

Orphaned, Haku became a child who was wanted by no one and was forced to take to the cold streets and rummage through trash bins for scraps of food, even sometimes having to fight off the wild dogs that roamed the streets. In time, he was found by Zabuza Momochi, who asked Haku to become his "weapon," which meant to become a dedicated shinobi for Zabuza. Haku readily accepted this role, due to the purpose it gave him, devoting his life to becoming the ultimate weapon for Zabuza. Zabuza then trained Haku in the ways of the shinobi, as well as every fighting technique that he knew.

In the anime, it was revealed that Haku and Zabuza met Kimimaro some time after Zabuza cast aside the Land of Water and set out with Haku. Haku appeared to sympathize with Kimimaro for his loneliness and lack of purpose by looking into his eyes. However, he was forced to keep moving by Zabuza, and leave Kimimaro be.

Appearance
Haku was a young shinobi and despite being male, he had a very feminine appearance and was viewed as quite beautiful, as Naruto exclaimed that he was "cuter than Sakura," after Haku informed him that he was male. Haku had had long black hair, which was to the length of his shoulder blades, pale skin and large, dark brown eyes. He had a slender frame and was also quite short for his age. Haku’s normal shinobi outfit consisted of a moss green, striped turtleneck sweater and a split skirt in matching colour that reached down to his knees. On the outside of that, he wore a green blue short kimono with white edges, and around his waist a green brown obi, in the same fabric as his sweater, with a fringed trail. He also wore light brown platoon sandals with straps in the same colour as his kimono and nail polish on his fingernails and toenails in matching blue green colour. When wearing this outfit, Haku’s long hair was gathered in a white bun holder tied with a green blue, while two locks of his hair fell loose framing his face, bound with metal hair cuffs at the ends. Haku also wore a black forehead protector with the symbol of his village Kirigakure. When in battle he was spotted wearing his former Hunter-nin mask on top of his forehead protector; a white mask with thin, curved eye-holes and a red wavy design in place of the mouth, as well as the Kirigakure symbol on the forehead.

When Haku was not in combat, as seen when he meet Naruto in the forest gathering herbs, he was seen looking very feminine. He had his long hair loose and wore a pink sleeveless, low-cut kimono, with pale red edges and decorated with small plum coloured swirls, that went to his ankles. Around his waist was a simple white obi tied in a bow, and he wore a pair of light brown sandals with dark straps. To add to his feminine appearance, he also wore a dark choker around his neck. As a small, homeless child Haku wore a large, shredded light brown shirt which fell of his shoulders, and a pair of shredded knee-length pants, as well as the dark choker. Later when taken in by Zabuza, Haku is spotted wearing a short blue kimono with light blue edges and a dark gray split skirt, similar to those ones he wore as a shinobi, and also similar to those he wore as a younger child when his parents were alive.

Personality
Haku was a good-natured, compliant, and eager shinobi, believing that a person becomes truly strong when they have someone important to protect. Despite his talent for battle, and incredible abilities, Haku disliked needing to kill others in his role as a tool, and avoided doing so whenever possible. When forced to face an opponent, Haku did all that he could to avoid inflicting great harm, even putting them into a death-like state to prevent them from fighting further, as he did to Sasuke during their battle. Before he met Zabuza, he suffered from a belief that he was unnecessary, and served Zabuza because he wanted to feel useful.

Abilities
Having been trained by Zabuza for years, Haku was a very dangerous ninja for his age. According to Zabuza, Haku possessed such prodigious talent that, in many ways, Haku had become more dangerous than him. Haku possessed a very detailed knowledge of human physiology, thanks to Zabuza's former ANBU training. His knowledge was great enough that he could disable an opponent with acupuncture by hitting a precise point on the body with a senbon, to cause immediate death or a temporary appearance of such. Haku was also very keen-minded, as he had been shown to have great observational and analytical abilities, capable of quickly determining a way around an opponent's technique or strategy. Haku also had the ability to perform hand seals with only one hand, a skill that amazed even Kakashi. Haku also appears to have knowledge of animals as he was able to detect the Allied Shinobi Forces' Surprise Attack Division based on the unusual flight pattern of the birds Sai had made.

Speed
Another defining trait of Haku's was his sheer speed. He was very fast with his attacks, such that Sasuke could not follow his actions until he had reawakened his Sharingan. Upon that moment, Zabuza was shocked that Haku would actually lose to Sasuke in terms of speed. He was also able to hold his own in speed against Rock Lee - who is also known for it due to his training.

His speed increased to incredible levels using his Demonic Ice Crystal Mirrors, making it appear like he was in all the mirrors at once at one point while he was just traveling in between them at extraordinary speeds. It was such that he could launch several senbon from all the mirrors, looking like he was literally in all of them.

Kekkei Genkai
Haku's most noticeable power was the utilization of water and wind chakra to create ice. His power over ice granted him special techniques, like the Demonic Ice Crystal Mirrors, which surrounds a target with mirrors that Haku could teleport between and attack from, even if his opponent is in the sky. During his flashbacks of his youth in the anime, Haku was shown to release large spikes made of ice when he was about to be killed by his father. He could also use water-style techniques, such as Thousand Flying Water Needles of Death, which causes the water on the floor to concentrate into needles with just one stomp on the ground.

With his Ice Release, he could create domes that were capable of blocking even multiple exploding tags at once.

Land of Waves Arc
When Zabuza was about to be killed by Kakashi Hatake, Haku appeared, disguised as a hunter-nin, playing the part by appearing to kill Zabuza. He took the body, and, elsewhere, revived him, leaving Zabuza to rest a week before he could have a rematch with Kakashi. During this time, he met Naruto, and had a conversation with him about their purposes in life and those they care about.

During Zabuza's second fight with Kakashi, Haku (wearing the same mask as when he saved Zabuza) was drawn into battle with Kakashi's students: first Sasuke and then Naruto. He trapped both with his Demonic Ice Crystal Mirrors, and bombarded them with needles, tiring them out. When Sasuke appeared to die protecting Naruto from a "fatal" blow (in actuality being put in a death-like stance), Naruto, in anger, tapped into the power of the Nine-Tailed Demon Fox sealed within him. He was able to attack Haku, and break through the mirrors, in turn breaking Haku's mask. Recognizing Haku from earlier, Naruto regained his senses in time to stop himself from killing Haku.

Haku, defeated, and thus of no further use to Zabuza, asked Naruto to kill him anyway. Though reluctant, Naruto tried to comply, if it would make Haku happy. Before Naruto could do so, however, Haku sensed that Zabuza was about to be killed by Kakashi. Finding one final purpose, he parried Naruto's attack and went to Zabuza, using himself as a human shield against Kakashi's Lightning Cutter. Before he died, he grabbed Kakashi's arm, hoping that in death he would be useful to Zabuza in defeating his opponent. Zabuza thanked him, and tried to cut through his body to kill Kakashi, but Kakashi was able to pull away from the attack.

When Zabuza's employer, Gatō, arrived soon afterwards, and chose to end his contract with Zabuza, he was quick to defile Haku's body. While initially unperturbed by this, Zabuza was brought to tears by the act when Naruto told him of how Haku felt about him. In a final act of repentance, Zabuza killed Gatō, at the cost of his own life. As he died from the injuries given to him by Gatō's men, Zabuza asked to be beside Haku in death, and asked if they could go to the same afterlife together.

Shinobi World War Arc
Haku is resurrected by Kabuto, along with other famous shinobi through the Summoning: Impure World Resurrection, to prepare for war. While marching for war, he talked with Zabuza about how odd was the situation, since his mind was clear but his body was moving on its own. However, he knew he was not in the afterlife anymore.

When his group was attacked by the Surprise Attack Division, Haku quickly set up a defense, protecting himself and Zabuza. Haku then detected the ink birds the Surprise Attack Division were riding upon and used a Demonic Ice Mirror to appear above them and shoot them down with senbon. Upon landing, he joined Zabuza and the other zombies with them in charging the downed division. The zombie group was stopped by the Third Division, Rock Lee being the one to stop Haku himself. Zabuza then talked with Kakashi who revealed that Naruto had improved vastly since they had fought. This news brought a smile to Haku's face who believed Naruto would only continue to improve.

After Kabuto upgraded his Impure World Resurrection with Orochimaru's chakra, Haku and Zabuza were able to resist being completely controlled for a short time. During this time, Haku asked Kakashi to stop them and further stated he believed he had failed in being Zabuza's tool due to Zabuza being dead as well. Kakashi informed him that he had succeeded and that Zabuza didn't simply view him as a tool. He then began to cry out of shock and silently thanked Zabuza before Kabuto gained complete control of him. Haku then killed several ninja along with Zabuza within Zabuza's mist before being stopped by Might Guy and Rock Lee.

After the rest of the last generation of Mist Swordsmen was summoned, Kakashi tried to disable Zabuza using a Lightning Cutter. Kabuto moved Haku into Kakashi's way as a shield for Zabuza, similar to how he blocked Kakashi in their first encounter. Haku then kept him still so that Zabuza could attack Kakashi.
