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 act in Ōnoki's place to help create an ideal society, through the act of replacing shinobi.

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 hypothesised 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.

Some fabrications have anomalies in their DNA, giving them access to rare nature transformation. Being a clone of Ōnoki, Kū has the kekkei tōta Dust Release, and Sekiei has access to the kekkei genkai Explosion Release, which he seemingly gained from being implanted with Explosive Clay. Overexertion of one's abilities can hasten the fabrication's death, such as Kakō's rapid usage of his Dust Rekease ninjutsu without resting for 20 seconds in between led him to his demise.
