Japanese Voice Actor: Takehito Koyasu
Date of Birth
May 5, 1967. T’s Factory, Koyasu’s official agency, lists his birth date as 1967年5月5日.
About Takehito
Takehito Koyasu is a Japanese voice actor affiliated with and representing T’s Factory, the agency he founded. His official profile lists JoJo’s Bizarre Adventure among his major credits, alongside roles such as Zechs Merquise in Gundam Wing, Aokiji in One Piece, Shinsuke Takasugi in Gintama, Roswaal L. Mathers in Re:Zero, and Hodgins in Violet Evergarden. Public reference sources also note that he is the representative director of T’s Factory.
Hometown
T’s Factory lists Koyasu as being from Kanagawa Prefecture, Japan. Public reference sources more specifically identify Yokohama, Kanagawa Prefecture as his birthplace.
Career Highlights
Dio Brando is one of Koyasu’s defining roles. Behind The Voice Actors shows him as the Japanese actor who has voiced Dio most often across the franchise, and T’s Factory includes ディオ / DIO from the JoJo series in his headline credits. That long-running association makes him the franchise-standard Japanese voice for Dio in the modern era.
Beyond JoJo, Koyasu has had a very broad career across anime and games. His official profile highlights roles such as Zechs Merquise, Ryosuke Takahashi, Aokiji, Shinsuke Takasugi, Roswaal L. Mathers, and Benno, while public voice-acting databases also prominently associate him with characters like Dio Brando, Aokiji, and Shinsuke Takasugi.
Full Current Filmography
The list below reflects documented credits verifiable from T’s Factory’s official profile and major public reference sources as of March 25, 2026. Because Koyasu’s career is extremely extensive and public databases do not always align perfectly, this should be treated as a source-backed documented filmography summary, not a guaranteed exhaustive list of every role.

Video games
T’s Factory’s official profile lists major game roles including Jade Curtiss in Tales of the Abyss, Lezard Valeth in Valkyrie Profile, Sasuke Sarutobi in the Sengoku BASARA series, Tatsuya Suou in Persona 2, Rei in Hokuto Musou, and extensive other game work. Public databases also connect him to later JoJo titles and many additional franchises.
Dubbing / other screen work
Koyasu’s official profile also lists substantial live-action dubbing work, including Alexander in The Time Machine, Fred in Scooby-Doo, Joker in Suicide Squad, and Dr. Sivana in Shazam!.
Critical Reception
Koyasu’s strongest publicly visible reception signal here is not a major awards trail from the sources I checked, but his longevity and role centrality. He has remained one of the most recognizable villain and cool-character specialists in Japanese voice acting for decades, and Dio is one of the signature performances most closely tied to his name in both official and fan-facing databases.
For Dio specifically, the clearest evidence of reception is durability across the franchise. Behind The Voice Actors shows Koyasu as the actor who has voiced Dio most often, and JoJo-specific references continue to identify him as the modern Japanese voice of Dio and related Brando variants. That strongly suggests his interpretation became the default Japanese performance for the character. That last sentence is an inference from the documented casting pattern.

English Voice Actor: Patrick Seitz
Date of Birth
March 17, 1978. Public reference sources list Patrick Seitz’s birth date as March 17, 1978, and Behind The Voice Actors lists his birthplace as Riverside, California, USA.
About Patrick
Patrick Seitz is an American voice actor, ADR director, and script writer. His official website says his voiceover career began in anime and Japanese RPGs before expanding into American games and animation, and that he has worked on more than 400 series and games over a career spanning more than 20 years. Public profiles also identify him with major roles such as Dio Brando in JoJo’s Bizarre Adventure, Scorpion in Mortal Kombat, Franky in One Piece, Jiren in Dragon Ball, Laxus Dreyar in Fairy Tail, and Isshin Kurosaki in Bleach.
Hometown
The clearest publicly documented origin point I found is Riverside, California, USA, which Behind The Voice Actors lists as Seitz’s birthplace. I did not find a stronger official hometown statement in the sources reviewed here, so I’m treating birthplace as the most supportable public location reference.
Career Highlights
For JoJo’s Bizarre Adventure, Seitz is the English dub voice of Dio Brando / DIO in the modern anime adaptation. Behind The Voice Actors identifies him as the actor who has voiced Dio the most often in English-language releases, including the 2015 TV release of JoJo’s Bizarre Adventure, Stardust Crusaders in 2017, and Stone Ocean in 2021.
Outside JoJo, Seitz has one of the most recognizable deep-voice résumés in English dubbing and game VO. IMDb and Behind The Voice Actors both prominently associate him with Scorpion, Franky, Jiren, Laxus Dreyar, and Isshin Kurosaki, which gives a good snapshot of the kinds of commanding, larger-than-life roles he is most known for.
Full Current Filmography
The list below reflects a source-backed documented filmography summary from the public sources I checked as of March 25, 2026. Because Seitz’s credits are extremely extensive across anime, games, and ADR work, and the sources reviewed here were stronger on major highlights than on a single normalized master list, this should be read as a documented current profile of verifiable credits, not a guaranteed exhaustive filmography.
Anime / TV animation
2000s–present major documented anime credits: JoJo’s Bizarre Adventure (Dio Brando / DIO), One Piece (Franky, plus other roles), Bleach (Isshin Kurosaki, Kenpachi Zaraki, and others), Fairy Tail (Laxus Dreyar), Dragon Ball (Jiren), Naruto (supporting roles), Hellsing (Luke Valentine), Ergo Proxy (Raul Creed), Fate/stay night (Sōichirō Kuzuki), Eureka Seven (Charles Beams), and Mushishi (Seijiro). These are directly supported by the biography and filmography-oriented public profiles I reviewed.
JoJo-related anime and games
2015: JoJo’s Bizarre Adventure (Dio Brando).
2017: JoJo’s Bizarre Adventure: Stardust Crusaders (Dio Brando / DIO).
2021: JoJo’s Bizarre Adventure: Stone Ocean (DIO).
Behind The Voice Actors specifically states that Seitz has voiced Dio the most often in English, across 3 titles in its current franchise count.
Video games
Public profiles identify Seitz with major game roles including Scorpion in the Mortal Kombat franchise, Bob Richards in Tekken, Bizarro in Injustice 2, and extensive additional game work. His official site says he has worked on over 400 series and games, but the source set I checked here did not provide a single complete chronological gameography clean enough to reproduce as an exhaustive list.
Voice direction / ADR writing
Seitz is also publicly identified as an ADR director and script writer, not just a performer. That dual role appears consistently across his official site, IMDb, and public reference profiles, and it is an important part of his industry profile.
Critical Reception
Seitz’s public critical standing is driven less by a single awards narrative in the sources I checked and more by sustained prominence across anime dubbing and games. Behind The Voice Actors highlights Dio Brando, Scorpion, and Franky as signature roles, which is a useful shorthand for how his voice-acting brand is publicly recognized.
For Dio specifically, the clearest reception signal is durability across the franchise. Behind The Voice Actors identifies Seitz as the English actor who has voiced Dio the most often, which strongly suggests his performance became the default English-language interpretation of the character for the modern anime era. That last sentence is an inference from the documented multi-title casting pattern.
