Vinsmoke Yonji

"Winch Green" Vinsmoke Yonji is a member of the Vinsmoke Family and Germa 66. He is Sanji's and Reiju's younger brother.

Appearance
As noted by the Straw Hats, Yonji heavily resembles his brother Sanji, having curly eyebrows like his siblings, and blonde hair which is slicked into a cowlick in the back. He wears all dark clothing, with his shirt bearing the number "66" on it and his hooded cloak bearing the number "4". He wears a striped belt with a skull buckle, metal gloves, and sunglasses and earphones on the top of his head.

Personality
Yonji is very callous and stingy, refusing to help the Straw Hats when he met them and telling them to fight him if they wanted an antidote from him. He is very proud, getting angry at his sister Reiju for shaming him. He is also respectful of his family's affairs, deciding to not get involved with the Straw Hats in order to ensure that Sanji's wedding will not be called off. Much like his brother Sanji, he exhibits some lecherous qualities, as shown when he saw Nami for the first time.

Abilities and Powers
Being part of the Vinsmoke Family, Yonji possesses great political power, although the extent of this power is currently unknown.

Equipment
Being from the technologically advanced Vinsmoke Family, Yonji possesses high-tech equipment. He possesses something in his shoes allowing him to levitate in midair.

Whole Cake Island Arc
Yonji first encountered the Sanji retrieval team right after they entered Big Mom's waters.

Luffy's group mistook him for Sanji until Yonji revealed otherwise. Seeing that the Thousand Sunny was not the ship Sanji was on, Yonji was about to leave. Chopper called out to him, still calling him Sanji, much to Yonji's annoyance. Chopper begged for an antidote to Luffy's poisoning, but Yonji taunted the group to try to take it by force. His sister, Reiju, appeared and kicked Yonji for his rudeness. After Reiju cured Luffy of his condition, Yonji and Reiju left the Sanji retrieval team alone without making a scene. They also decided to pretend that they never saw the Straw Hats to prevent Sanji's marriage from being called off.
