All lifeforms have the Lineage Factor, and by manipulating it from a young age the growth of a lifeform can be changed.
Using the Lineage Factor, and later gene manipulation, Vinsmoke Judge was also able to enhance humans, specifically his children, and some soldiers from his army that he later cloned. However, Judge found out that the process can have its failure rates, as Sanji remained as a normal human despite modifications.
Vinsmoke Judge conducted several researches and experiments with the Lineage Factor, becoming able to artificially manufacture human beings to fill the soldier ranks of Germa 66. Those soldiers are known as "Clone Pawns" and they are made without the knowledge of their origin.
- The Lineage Factor is a reference to DNA, the molecule that contains all the genetic information of the host organism.
