When the mastermind scientist Amado Sanzu made his official anime debut in Boruto: Naruto Next Generations, fans immediately wanted to know who would bring the calculating former Kara member to life in English. The English dub reveal answered this question by casting veteran voice actor Greg Chun in the role.
Amado's introduction shifted the entire narrative arc of the series. As the brilliant mind behind Kara's advanced scientific ninja tools and genetic modifications, his transition from the shadows to Konohagakure required a voice performance that projected cold intellect, cynicism, and deep hidden motives. Greg Chun stepped into this pivotal role, delivering a measured, gravelly, and sophisticated tone that matched the Japanese voice performance of Akio Ōtsuka.
Understanding Amado's Role in Boruto
Amado isn't just another side character or standard villain. As the Head of Research and Development for the Inner Kara organization, he engineered technology that rivaled Otsutsuki god-level abilities. His defection to the Hidden Leaf Village remains one of the most strategic turning points in the narrative.
Konohagakure's leadership had to weigh the immense risks of harboring a high-ranking enemy scientist against the critical intelligence he possessed about Jigen, Isshiki Otsutsuki, and the Karma mark. Because Amado relies entirely on intellect, psychological manipulation, and sheer preparedness rather than raw physical combat, the voice acting needed to convey absolute composure under pressure.
Greg Chun: The Voice Behind the Scientist
Greg Chun is a heavyweight in the voice acting and video game industry, known for his deep, commanding, and versatile vocal delivery. Before stepping into the role of Amado, Chun built an impressive resume voicing complex characters across major anime and gaming franchises.
Some of his notable prior roles include:
- Goro Akechi in Persona 5
- Dimitri Alexandre Blaiddyd in Fire Emblem: Three Houses
- Muzan Kibutsuji in Demon Slayer: Kimetsu no Yaiba
- Yutaka Sado in Aggretsuko
His experience playing brooding, intelligent, and morally ambiguous characters made him an ideal fit for Amado. Fans watching the English dub praised how well Chun captured the character's unbothered demeanor, especially during high-stakes interrogations with Naruto Uzumaki and Shikamaru Nara.
Comparing English and Japanese Voice Performances
Voice-casting for major shonen adaptations often faces intense scrutiny, especially when dealing with fan-favorite anti-heroes and antagonists. In the Japanese broadcast, Akio Ōtsuka lent his iconic, deep rumble to the character. Ōtsuka is legendary in the anime industry for voicing heavyweights like My Hero Academia's All For One and Bleach's Shunsui Kyoraku.
Matching that level of gravitas is no small feat. Greg Chun adopted a similar vocal register—calm, unhurried, and laced with quiet menace. Instead of leaning into cartoonish villainy, Chun played Amado as a tired, pragmatic professional who viewed everything as a calculated equation. This grounded approach helped the English dub maintain the serious, political thriller tone of the Boruto manga's later arcs.
How the Dub Reveal Impacted the Community
Anime streaming schedules often release dub episodes months behind the subbed version, creating intense speculation within online fan communities. When Viz Media and the official production teams announced the English voice cast additions for the Kara Inners, the community dissected every line.
Discussions spanned across Reddit, MyAnimeList, and dedicated anime wikis, focusing heavily on whether Western voice actors could pull off the cynical weight of characters like Amado, Code, and Eida. Chun's performance quickly won over skeptics, particularly during key dialogue-heavy scenes where Amado negotiates his asylum in Konoha using explosive intel on the Otsutsuki threat.
