Veteran Japanese voice actor Norio Wakamoto, represented by the Sigma Seven agency, lent his booming baritone to Ganzack in the One Piece anime from Toei Animation.
In the Japanese-language version of One Piece, Wakamoto provides the voice of Ganzack, applying the deep, gravelly delivery that runs through much of his catalog. The role is a comparatively brief entry set against a filmography built mostly around imposing villains, commanding officers, and comic-menacing side characters across anime, tokusatsu, and games. Wakamoto's instantly recognizable timbre has made him a frequent choice for such parts throughout a career spanning more than five decades.
Born in 1945 in Shimonoseki and raised in Osaka's Sakai ward, Wakamoto studied at Waseda University before building a voice acting career that has run continuously since the early 1970s under the Sigma Seven agency. On adult-oriented titles such as OVAs and dating sims, he records under the pseudonym Kyonosuke Hiruma. Decades in the industry have made his booming baritone one of the most recognizable voices in Japanese media, regularly cast in imposing, villainous, or comedic roles.

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...
