One Piece: 5 Strongest Characters You've Never Heard Of, Ranked

From god-tier monsters to legendary pirates and vicious marines, Eiichiro Oda's One Piece features roughly a billion powerful characters who can destroy islands on their own. Due to the manga and anime's popularity, none of the canon characters could be described as unknown, and the same can be said for the movie's "filler" villains. However, One Piece games are the exception, as the franchise has never fully established itself in the medium to the same extent as, say, Dragon Ball or Naruto.
