Ice Release

Haku's kekkei genkai, allowed him to combine wind and water-based chakra to create ice, which he could manipulate through willpower alone. The ice Haku created was largely immune to fire-based attacks, only melting slightly when coming into contact with flames. Using his special ability, Haku developed the Demonic Ice Crystal Mirrors, which allowed him to create any number of mirrors made of ice to use as a shield or trap an opponent.

In the first Naruto movie, several of the Yukigakure ninja also had the ability to use Ice Release techniques. However, this was not the product of a similar kekkei genkai, as demonstrated by Kakashi's ability to replicate one of these techniques with his Sharingan. In addition, unlike Haku, who could create his own ice, the Ice Release techniques used in the movie required the users to manipulate already existing ice. The Yukigakure ninja used hand seals in their ice manipulation abilities. These Ice Release techniques commonly used the Dog hand seal.
