In a bold move that will light up the summer of 2026, Ishimori Production has revealed the complete voice cast for its upcoming anime adaptation of Shotaro Ishinomori’s legendary Cyborg 009 manga, Cyborg 009: Nemesis. The series is slated to stream worldwide during the summer season, and the announcement comes with a star‑studied lineup of voice actors, a fresh theme song, and a seasoned creative team led by director Hideki Ambo and studio Arect.

The title hero, Joe Shimamura—better known as Cyborg 009—gets the vocal heft of Yūki Kaji. The remaining eight members of the 00 Cyborg squad are voiced by a cadre of well‑known talent: Yū Hayashi as Cyborg 008/Pyunma, Kentarō Tone as Cyborg 007/Great Britain, Mitsuaki Kanuka as Cyborg 006/Chang Changku, Hiroki Yasumoto as Cyborg 005/Geronimo Junior, Tomokazu Sugita as Cyborg 004/Albert Heinrich, Saori Hayami as Cyborg 003/Francois Alnul, Mamoru Miyano as Cyborg 002/Jet Link, and Junko Minagawa as Cyborg 001/Ivan Whiskey. The Nemesis team—an antagonistic squad of nine cyborgs—brings its own roster of voices: Yūichi Nakamura (Nemesis 009/Graviton), Ayane Sakura (Nemesis 008/Deps), Maaya Uchida (Nemesis 007/Morphone), Shion Wakayama (Nemesis 006/Blitz), Tetsu Inada (Nemesis 005/Aspida), Kikuko Inoue (Nemesis 004/Opro), Hiroshi Kamiya (Nemesis 003/Crack), Yoshimasa Hosoya (Nemesis 002/Blizzard), and Rina Hidaka (Nemesis 001/Mu).

According to the official website, the series’ writers include Atsuhiro Tomioka—known for his work on Pokémon—and the collective CHARATEX, while character design is entrusted to sanorin. Hideki Ambo directs the project at Arect, a studio that has delivered several recent anime titles.

The opening theme, “Taga Tame ni” (誰がために), is performed by Kyōko, the frontwoman of the rock band Barbee Boys. The track originally debuted in the 1979 Cyborg 009 television series and was penned by Ishinomori himself. The new rendition is billed as a faithful homage, featuring updated arrangements that align with the contemporary tone of the adaptation.

Cyborg 009 first appeared in Shōnen King magazine in July 1964 and has since spawned a wide array of media. The franchise includes television anime series (1968, 1979, 2001), feature films (1966, 1967, 1980), two recent movies—009 Re:Cyborg (2012) and Cyborg 009 Call of Justice (2016)—and an OVA crossover with Devilman (2015). In 2019, Tsuguo Okazaki launched Cyborg 009 Bgooparts Delete, which concluded in September 2022, while a new manga, Cyborg 009 Taiheiyō no Bōrei (Cyborg 009: Ghost of the Pacific), began serialization in April 2024.

The full‑cast announcement and new theme song are part of a broader marketing push ahead of the series’ summer release. While the exact premiere date remains undisclosed, the official website confirms that the show will “stream” in the summer of 2026.

Industry observers note that the blend of veteran voice talent, a respected production crew, and a nostalgic theme song positions Cyborg 009: Nemesis to appeal both to long‑time fans and to newer viewers drawn by the polished, contemporary anime style. The timing also dovetails with the traditional summer programming cycle, a period that historically sees heightened viewership for fresh anime titles.

At this stage, no additional details about episode count, episode length, or distribution partners have been released. Fans of the original manga and its previous adaptations can expect a fresh take on the classic narrative, with the production team’s stated goal of delivering a “modern yet faithful” rendition of Ishinomori’s vision.

Next steps for the project include finalizing distribution agreements, setting a precise premiere date, and launching promotional materials such as trailers and character art. Once those details surface, the anime community will be able to gauge the series’ potential impact on the current landscape.

In summary, Cyborg 009: Nemesis brings together a strong cast, a seasoned creative team, and a celebrated theme song to launch a new chapter in a storied franchise. The series is slated to stream in summer 2026, marking the next major entry in the Cyborg 009 legacy.
