Choudenshi Bioman

Choudenshi Bioman, which aired in 1984, is notable for being the first Super Sentai series to feature two female warriors on the core team. It was also the first Sentai to have the heroes possess inherent superpowers outside of their suits, utilizing "Bio Particles" to fuel their biokinetic abilities. These innovations set new standards for future Sentai shows.

The series follows five young people who are descendants of humans infused with Bio Particles by the robotic Bio Robo centuries ago. When the evil Neo Empire Gear attempts to conquer Earth, the heroes transform into the Biomen to defend the planet. Their main antagonist is the cyborg villain Doctor Man.

Yes, Bioman was actually the very first Super Sentai series to be officially broadcast internationally. It was translated and aired in France and the Philippines in the late 1980s, gaining a massive cult following. This international exposure predated the worldwide Power Rangers craze by nearly a decade.

The show was produced by Toei Company and aired on TV Asahi from February 1984 to January 1985. It was the eighth entry in the long-running Super Sentai franchise. It laid the foundational sci-fi tropes that many later Sentai shows would build upon.
