Yo

King Yo is the current ruler of the subnational Kingdom of Yi. According to Olivia, Yo was the 36th generation descendant of the first King of Yi. During Anthony's quest to unite the warring states of Zion after the fall of Dragases, Yo refused to peacefully surrender his state to Anthony, resulting in a long-standing conflict. After the Kingdom of Yi finally starved to submission, Yo remained the de-facto ruler of the kingdom.

King Yo was rumored to be dead in Zion City, but this has yet to be confirmed.
