It has a cult following in the Philippines since they made their own English dub of it (which had the characters' names anglicized) long before Mighty Morphin' Power Rangers. Giving rise to homages like Kabayoman (kabayo meaning horse, and bayo is pronounced like bio) and Biokids.
And how about the cult following they have in France? It got to a point that, when Maskman and Liveman were ported there, they were respectively renamed Bioman 2 and Bioman 3!!! No wonder the idea of France Five worked out so well.
Farrahcat was played by Yukari Orishima, who played Rogan in The Story Of Ricky. She later becomes a famous action star, going by the screen name Cynthia Luster.
Hikaru Kurosaki, who played the Bioman pretender Yamamori in Episode 35 and 36, is better known for his role as the title character in Kyojuu Tokusou Juspion.
Tokie Shibata, who played the android schoolgirl Miki in Episodes 43 and 44, would play a recurring role in Dengeki Sentai Changeman as the teenage version of Nana.
Shuichi Kageyama and Prince were both played by Hidenori Iura, who also played Tatsuya, one of the Comboys in Dai Sentai Goggle Five. He went through puberty since Goggle Five ended, so he looks very different here.
Mason, Dr. Man's second-in-command, is played by Hirohisa Nakata who also played Great Emperor Zero, the Big Bad from the second half of Kamen Rider Amazon.
