Led by the scientific genius of Vinsmoke Judge, the Germa Kingdom is the only known seafaring nation in One Piece, whose origins lie in the North Blue. Famed for their advanced technology, the ruthless policy of conquest, and the strength of the members of the Vinsmoke royal family, who are all powerful combatants in their own right, the Germa Kingdom was formerly affiliated with the World Government and enjoyed a high degree of authority among the member nations despite the many underhanded moves made by both Judge and his ancestors. The kingdom was first introduced during the Whole Cake Island Arc, with the reveal of Sanji as a member of the ruling Vinsmoke royal family. At the time, the Straw Hats' cook was being forced into a marriage to Charlotte Pudding, the daughter of Big Mom, in a bid to cement an alliance between the Germa Kingdom and the Big Mom Pirates. However, this fell apart due to the intervention of Luffy and the Minks, as well as the revelation that Big Mom and her children intended to kill the Vinsmoke family and seize their technology by force.
