Having no fixed appearance or smell, this technique allows White Zetsu alter his form and chakra, at will. In becoming the perfect duplicate of another individual, he will even possess chakra identical to that of the one that he is impersonating along with any clothing they might be wearing or tools they may be carrying. Typically, White Zetsu would employ his parasite clones to serve as substitutes; he was able to control these clones remotely and remained aware of their actions and experiences. The transformed clones can even retain the appearance of the person they were impersonating after death, reverting to its true form only after the technique was voluntarily released by the original White Zetsu. Because the substitute is weaker than the original individual, their primary purpose is to function as a diversion.
In the effort to increase the Akatsuki's military power, Kabuto Yakushi conducted research to enhanced the strength of the White Zetsu Army. As demonstrated throughout the war, the soldiers can use this technique to copy a target's abilities, to the extent of what is known to them. Though, it was only in the anime, however, that they were shown actually using copied techniques. Also, unlike the original's version, the technique is seemingly dispersed once the transformed soldier is dealt with a significant amount of damage or killed. Additionally, these clones demonstrated the ability to partially revert to their true forms while transformed.
In the manga, the clone used as a substitute for Kisame Hoshigaki resembles a regular parasite clone. In the anime, however, the clone possesses the Venus flytrap-like extensions that protrude from the side of the original White Zetsu, as well as the clothing that White Zetsu was wearing at the time.
In both the manga and anime, the transformed clones were shown to bleed when damaged. However, in Road to Ninja: Naruto the Movie, limbs severed from transformed clones were shown to leak a white substance, similar to Obito Uchiha's artificial arm. One clone was also shown to regenerate its lost limb upon reverting to its true form.
