Bertholdt Hoover in Attack on Titan is voiced by Tomohisa Hashizume in the Japanese version and David Matranga in the English dub. Both actors bring a restrained, inward quality to the role that suits Bertholdt’s defining trait as a character — a quiet, conflict-ridden soldier concealing an enormous secret beneath an unassuming exterior.
Tomohisa Hashizume (Japanese Voice Actor)
About Tomohisa
Tomohisa Hashizume (橋詰 知久) is a Japanese voice actor whose work spans anime, video games, and other voice media. He is best recognized internationally for his long-running portrayal of Bertholdt Hoover across multiple entries in the Attack on Titan franchise, a role he has reprised consistently from the 2013 original broadcast through Attack on Titan: The Final Season.
Hashizume brings a carefully measured softness to Bertholdt that reflects the character’s internal conflict and social anxiety. His vocal delivery tends toward the understated, making the moments when Bertholdt is pushed to his emotional limits — particularly in the Shiganshina arc — land with considerable weight. This restraint is one of the qualities that has made his performance memorable among fans of the series.
Beyond Attack on Titan, Hashizume has accumulated a varied catalogue of supporting and secondary roles across anime and video games, demonstrating a range that extends well beyond a single defining credit.

Critical Reception
Hashizume’s portrayal of Bertholdt Hoover has been well regarded within the Attack on Titan fanbase, particularly for how effectively he communicates the character’s suppressed guilt and loyalty through subtle vocal choices rather than overt dramatic expression. The character’s page on MyAnimeList lists Hashizume as the primary Japanese voice actor, reflecting the consistency of his involvement throughout the entire run of the franchise.
David Matranga (English Voice Actor)
About David
David Matranga is an American voice actor who has worked primarily in English-dubbed anime since the late 1990s. Based in Texas and represented by Pastorini-Bosby Talent, he has been an active presence in the dubbing industry for well over two decades, accumulating credits across a wide range of genres and character types.
Matranga is perhaps most widely known to mainstream anime audiences as the voice of Shoto Todoroki in My Hero Academia, a role that significantly raised his profile internationally. His performance as Bertholdt Hoover in Attack on Titan predates that breakout credit and is considered one of his signature earlier roles, praised for capturing the character’s understated demeanor and the creeping dread of his eventual reveal as the Colossal Titan.
His vocal approach tends toward calm, measured delivery with the capacity for controlled emotional intensity — qualities that serve both Bertholdt’s passive exterior and the character’s more desperate final moments in the series. Matranga has reprised the role across multiple Attack on Titan entries, including films and The Final Season.
