Clone Techniques (分身術, Bunshinjutsu) are techniques that create copies of the user or their tools. Though the standard Clone Technique is considered the most basic of ninjutsu, these techniques are highly versatile, often used to distract enemies or fool them into thinking they have landed a hit on the user. Corporeal clones can aid the user in physical combat, and even use techniques independent of the original. There are varying methods of creating clones, some techniques using only chakra while others require some sort of medium to give the clones form and substance. There are also clone techniques that transform another person or animal into a clone of the user, such as the Beast Human Clone, as well as genjutsu which create illusory clones, such as the Mist Servant Technique.
During his experiments on Shin Uchiha, Orochimaru developed a variant of clones, which were considered to be a higher class than the Shadow Clone Technique. The results are that each one is the same as the original, and that they will not disappear even if struck with sufficient force; the only method of dispersal is killing them. In a way, they are similar to White Zetsu's Parasite Clone, though unlike them, they have their own sense of individuality and free will, leading them to betray the original Shin when they see fit. These clones have also created their own clones without the original's notice, but had done so improperly, which resulted in various genetic and physical defects.
- Ninjutsu within this category of techniques are also known as Clone Ninja Techniques (分身忍術, Bunshin Ninjutsu).
- While there a wide variety of clone techniques using different nature transformations have been introduced, there has yet to be one using Fire Release or Wind Release.
