|~ Vinsmoke Yonji|
Vinsmoke Yonji is the youngest son of the Vinsmoke Family and a high-ranking member in Germa 66. Yonji like his brothers, Vinsmoke Ichiji and Vinsmoke Niji, was born without empathy and actual emotions. Yonji alongside his siblings were responsible for abusing Sanji when they were kids. Yonji is an antagonist in the Whole Cake Island Arc in the One Piece anime and manga.
He is voiced by Kenjiro Tsuda as an adult, and Akemi Okamura as a child.
Because of Vinsmoke Judge's unethical experiments on the Vinsmoke siblings, Yonji like Ichiji and Niji was born lacking empathy and any human emotions outside of being prideful, antagonistic and violent. As a kid, Yonji was prideful in the Vinsmoke Family and Germa 66 and was loved by his father for being a very strong. In return, Yonji alongside his brothers would constantly bully and belittle Sanji for being weak. When he heard of Sanji's death, he did not care about it even smiling. Over time, Yonji like his brothers grew to have more pride in Germa 66 and the Vinsmoke Family.
As an adult, Yonji grew up to be as antagonistic as his brothers. Unlike his more colder older brother, Ichiji or his other more sadistic and violent brother Niji, Yonji is more snobbish and condescending when it came to looking down on his brother. He mostly preferred to insult Sanji when he was around him. When he fought Sanji upon meeting him after over a decade, he was surprised to see how strong he became when he lost to him in battle and was angry that he lost to someone he had previously considered much weaker than him.
Like his brothers, since he lacks actual human emotions outside of being prideful and cruel, Yonji did not fear dying at the hands of the Big Mom Pirates when they were about to assassinate him and his family. After the assassination attempt and the betrayal from the Big Mom Pirates, Yonji like his siblings seek vengeance against them and decided to attack the Big Mom Pirates on Cacao Island and helping Sanji and Luffy escape from them too.
In the past, Yonji was born and gain superhuman strength and power from the unethical experiments Judge performed on him while he was still in his mother. Because of this, Yonji gained superhuman strength like his other siblings and he would train to become a strong member for the Germa 66 army. At the same time, he would constantly abuse Sanji for being weak and kind than the rest of the family. When he heard that Sanji died from Judge, Yonji did not care. Over time, Yonji alongside his brothers would grow to become high-ranking members in Germa 66.
