Haku was born in a snowy village somewhere in the Land of Mist. He inherited the Hyoton bloodline limit from his mother, which gave him the ability to control ice by combining water and wind chakra. When his father discovered that his wife and son had this mysterious and dangerous bloodline ability, he killed Haku's mother and attempted to kill Haku. Haku panicked and his body responded by summoning large ice crystals that pierced his father, killing him. He became a beggar and wandered the land until he was found by Zabuza Momochi, one of the Seven Swordsmen of the Mist, who took him in under his wing because of his powerful Hyoton ability.
Major Story Arcs
Land of Waves ArcZabuza and Haku are hired by a man named Gato to assassinate the bridgemaker Tazuna, who is being protected by Team 7 (Kakashi, Naruto, Sakura, and Sasuke). During the initial fight where Zabuza is severely wounded by Team 7, Haku saves Zabuza by throwing needles through some of his pressure points, putting him in a catatonic state. Team 7 assumes that Haku is a ninja that has come to retrieve Zabuza and dispose of his corpse, as Zabuza is a missing-nin and contains secrets that must not be revealed to other ninja villages - unfortunately for them Zabuza is not actually dead. Haku leaves with the comatose Zabuza and revives him in a secluded forest area. Haku later goes out to gather herbs to help Zabuza heal quickly, and while gathering he meets an exhausted Naruto who he talks to about his life's goal of protecting the one who he loves the most. Naruto is confused by Haku's androgynous appearance and believes that he is a girl. While Haku is walking away, he leaves Naruto with the knowledge that he is, in fact, a boy.
Later on, Haku and Zabuza confront Team 7 on the partially-constructed bridge. He and Sasuke begin to fight and Haku uses his Hyoton limit to use 1000 Needles of Death, which summons a barrage of ice needles that fly at the enemy. Sasuke is pushed back initially, but starts matching Haku blow for blow. Haku decides to use his "Demonic Ice Mirrors" technique, which summons an assortment of the titular ice mirrors, which he can merge into and teleport between at extremely fast speeds. He quickly depowers Sasuke by moving between his ice mirrors, piercing Sasuke with Ice Needles. Before he can defeat Sasuke, Naruto jumps in between the ice mirrors, trapping himself but allowing him to protect Sasuke.
Haku still has the upper hand, but Sasuke's awakened Sharingan enables him to be able to see Haku's movements by watching the movement of water droplets on the ground. Sasuke starts getting closer to hitting Haku, but is severely wounded when he jumps in the way of an Ice Needle barrage meant for Naruto. Sasuke becomes unconscious, allow it appears that he has been killed. Later it is revealed that Haku spared Sasuke's life by only hitting non-vital parts of his body. Naruto, believing Sasuke dead, unleashes some of the demon fox's power, and he is able to fight Haku successfully, eventually punching him through one of his own ice mirrors, shattering it in the process. Haku, having lost to Naruto, asks to be killed because he is of no use to Zabuza as a tool. Naruto hesitates, discovering that Haku is in fact the person he met earlier when half of Haku's mask breaks off. As Naruto walks towards Haku, Haku stops him, saying that he has one last mission to accomplish. Haku teleports in front of Zabuza, taking Kakashi's Lightning Blade attack, which was meant for the defenseless Zabuza. Haku dies happily, hoping that his life was of some use to his master.
