A clone that is created by using chakra to alter the user's own cells into vegetation. The clones can be as simple in function as a wooden dummy for use in the Body Replacement Technique or completely mobile and able to perform techniques. They have the ability to travel far from the user and are able to communicate with the original. Moreover, since the wood clone has the ability to merge with plants and trees, it is also great for reconnaissance missions. By directly touching the wood clone with his hand, the user can absorb the information it gathered and change the shape of the clone. Unlike other clone techniques, the wood clone doesn't disappear when hit and takes the damage to a certain degree. This, according to Madara Uchiha, makes it the perfect clone technique that only he, with his dōjutsu, was able to see through. Also, unlike the Shadow Clone Technique, which requires the clone to disappear to relay intel back to the user's original body, the Wood Clone can relay intel back and forth between the user's original body and a clone without having the clone disappear or even coming into contact with each other. These clones can also be dispelled like normal clones, however.
If a wood clone is changed into a seed and ingested into the body or left on a target, it can be used as a transmission device of sorts. The user can use these to track their target as the seeds respond to their chakra only.
When Madara used this technique, he called it a "Wood Release Clone" (木遁分身, Mokuton Bunshin).
When Hashirama used this technique, he called it "Wood Release: Wood Clone Technique" (木遁・木分身の術, Mokuton: Moku Bunshin no Jutsu).
