Hikaru Kurosaki in Episodes 35-36 of Bioman
Before Hikaru Kurosaki became his iconic role Juspion, he was cast in Bioman episodes 35-36 as Shota Yamamori who wanted to join the Biomen but was refused because he didn't have any bio particles in him. Also in there, he met his future wife the late Yuko Asuka who acted as Farrah in that series. It's no surprise he became Juspion's human identity considering his martial arts prowess in those two episodes is freaking awesome!
In episode 36, after his character Shota was refused because he didn't have bio particles, Farrah tricked him into becoming the Magne Warrior to defeat the Biomen. I guess this was all a test to try out the formula for Juspion where he is the main hero.
Later he did retire from show business and ran a diving business with his wife Yuko Asuka but too bad she had left him for the afterlife so soon when she died.
