Despite this, clone techniques are very versatile and useful, and are often used to distract or fool enemies into thinking that they have delivered a critical or fatal hit to the user, leaving the enemy vulnerable. The various villages have created their own characteristic forms of clone techniques. Besides these, there are a dozens of other clone techniques in existence, some of which are extraordinarily difficult to use.
There are various methods of creating clones. The most commonly used clone techniques use only chakra to create the clone. After these, clone techniques that use a medium seem to be most common. These clone techniques use various elements to give the clone form and substance. There are water, sand, insect,mud,and clay clones. There are also clone techniques that transform another person or animal into a clone of the user. Finally, there are clone techniques that make use of genjutsu to create illusionary clones.
