Haku

was a villager from the Land of Water. He later became a Ninja after meeting Zabuza Momochi. Haku has the kekkei genkai ability of Ice Release, which allow him to control two types of nature chakra. He is able to control both water and wind chakra; this gives Haku the ability to use ice chakra, a mixture of the two.

Early Life
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, which are passed down through the generations. 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 ability 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 the 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 Ice Release's ability. After a slap to Haku's face and a few harsh words, Haku's mother embraced her child and apologized.

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 that evening and killed his wife. He would have done the same to Haku, but before he could, Haku killed them.

Orphaned, Haku became a child who was wanted by no one. Haku 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 mongrel dogs that roamed the same streets eating the same scraps of food.

Life with Zabuza
Some time after this Haku met Zabuza Momochi, a missing-nin from Kirigakure. Zabuza asked Haku to become his "weapon", which meant to become a dedicated kekkei genkai 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 shinobi, as well as every fighting technique that he knew.

Appearance
Haku has an androgynous appearance. Naruto exclaims that he is "prettier than Sakura" after Haku informs him that he is male. He can also been seen at times wearing clothing which shows a slightly more masculine appearance, or at others a more feminine appearance. Haku has straight, long and flowing, black hair that is just about to the length of his shoulder blades. He also has pale skin and brown eyes. He is also quite short for his age, being only 5"1 (five feet and one inch).

Personality
Haku is 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 dislikes needing to kill others in his role as a tool, and avoids doing so whenever possible. When forced to face an opponent, Haku does all that he can 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 serves Zabuza because he wants to feel useful.

Land of Waves arc
During Team 7's mission to the Land of Waves, Haku appears as a hunter-nin, giving the impression of being sent to kill Zabuza when in reality was there to save him. Haku was soon revealed to be Zabuza's subordinate in the story and fought Sasuke Uchiha and Naruto Uzumaki on the Great Naruto Bridge.

Prior to his defeat by Naruto, Haku's purpose in life had been to fight for and protect Zabuza and his dream of ruling over the Land of Water. His defeat at the hands of Naruto made him believe that there was no longer any purpose in living, because he then considered himself to be "weak" and of no use to Zabuza. Having lost his only purpose in life, he wished for death. But before Naruto could reluctantly deal the finishing blow as requested, Haku used the Demonic Ice Crystal Mirrors and senbon to release Zabuza from Kakashi's summoning and take the full force of his Lightning Blade. Haku's noble and selfless sacrifice for the one who mattered most allowed Zabuza to avoid certain death. Unfortunately, despite Haku's last efforts, Zabuza was eventually defeated by Kakashi and then killed by the combined efforts of Gatou's hired thugs before he managed to kill Gato. When Haku was dead on the floor and Zabuza was next to him, he thought about his ways in treating Haku and was finally able to understand his love for Zabuza. Before Zabuza dies, he whispers in Haku's ear that he won't be with him in the next life,but in the manga he hopes to be with him, but that he will be in a better place. Even though Haku died, a tear passed down his face and then Zabuza died happily knowing that Haku was happy.

Other involvement
In the anime, it is 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 let Kimimaro be. The manga does not present this meeting.

In Part II, when Naruto is training to use his Wind type chakra to it's fullest potential, Kakashi and Yamato explain Kekkei Genkai to him. Kakashi uses Haku as an example, telling Naruto that the reason Haku could use Ice Release is because he combined Water and Wind-based chakra to form Ice.

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 very detailed knowledge of human physiology thanks to Zabuza's former ANBU training. His knowledge was great enough to that he could disable an opponent from action by hitting a precise point on the body with a senbon to cause immediate death or the a temporary appearance of such.

Speed
In battle, Haku fought with tremendous speed and dexterity, possibly with assistance from his wind-chakra reducing wind resistance. His speed was great enough that his movements couldn't be seen with untrained eyes. Haku's preferred battle tactics revolved around the usage of senbon. He had been trained to throw them with pinpoint accurancy.

Ice Style
Haku's most noticeable power was the utilize water and wind-chakra to create ice. His power over ice granted him special techniques, of which the only one seen in the anime or manga is Demonic Ice Crystal Mirrors, which causes the air around him and his opponent to become much colder and then appears with dozens of crystal ice mirrors. On all of these mirrors appears Haku and is able to teleport from one mirror to other and causes major damage with the use of his senbon. Others are believed to have existed due to the his use of ice to save himself from his father. Some have been made in several Naruto video games. he also can 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.

Smartness
Haku was also very keen minded as he has shown great observational and analytical abilities, capable of quickly determining a way around an opponent's technique or strategy.

Dexterity in Hand Seals
Haku also had the ability to perform Hand Seals with only one hand. Whether this is a product of his Kekkei Genkai or not is unknown.
