Fabrication

A is an imperfect synthetic human that is created from the genetic material of a White Zetsu by a scientist in the service of Ōnoki. Regarded as not having a will, their purpose is to replace shinobi. The first fabrication created was Kū, who was created as a clone of Ōnoki using his DNA, and as such, manifested his kekkei tōta Dust Release.

The fabrications have limited lifespan, resulting in cracks appearing on the body when they weaken; there is no solid time each of these individuals have, but Ōnoki suggested it can range anywhere from months to the next day of their creation before they expire. Upon researching a different type of synthetic human, Mitsuki, the scientist hypothesized that by replacing the fabrication's heart with a natural human's they can stabilise the artificial bodies and extend their lifespan. This theory has yet to be tested, as Kū refuses to let it happen without Ōnoki's permission.
