The Substitution Technique is a unique ninjutsu of White Zetsu, allowing his biological parasite clones to take on the appearance of anyone they or the original have touched. Unlike the ordinary Transformation Technique, the copy becomes perfect: it adopts not only the target's appearance but also their unique chakra, including any characteristic features, as well as an exact likeness of their clothing and carried weapons. The parasite clone, having transformed into a specific person, can maintain that appearance even after its death, returning to its original form only at the will of the original White Zetsu. Since the duplicate is inferior in strength to a real shinobi, its main role is to distract and confuse the enemy. The original Zetsu remotely controls his copies and is fully aware of everything they see and do.
