Will of the D. (One Piece)

In the series, few characters have the middle initial "D.". This mysterious middle initial has been called "the Will of D" (Dの意志, D no Ishi) or "D's will" by several characters in One Piece. Some translations mistakenly refer to it as "Gol D's will" in reference to Gol D. Roger, the late pirate king. The English dub by 4Kids chooses to refer to the D as the "Gol D.'s will", while the FUNimation dub refers to it simply as "the Spirit of D." both deriving from a mistranslation of the original Japanese text. In the recap supplement Grand Line Times, they were referred to as "The men of D."

Yonko (One Piece)

The Yonko are considered to be the world's most notorious pirate captains (by the World Government), but are neither allies nor enemies of one another, preferring to remain independent under most circumstances. These four individually reside within the second half of the Grand Line (known as the "New World"), exerting impressive influence/control over dozens of other pirate crews and self-governing islands. In the climactic Battle of Marineford, one of the Yonko met his end towards the climax of the Whitebeard War, his assassin subsequently replaced him, while another member stopped the aforementioned war.
