Four Brother Vinsmoke - Germa 66 Tapestry

Four Brother Vinsmoke The children of the Vinsmoke Family were genetically modified by Judge, specifically for the purpose of creating elite military commanders who would lead Germa 66 to achieve Judge's ambitions. However, one of the children, Sanji, was disowned from the family. Sanji was labeled a 'failure' in his early childhood, after exhibiting undesirable behaviors to Judge and consistently being outperformed by his siblings in physical tests. These modifications are the reason for the Vinsmoke siblings' different hair colors. Sanji is the only sibling to inherit his parents' hair color due to the modification's failure on him.
