Plot
Naoto Tamura, a new detective in Central City, is killed by a Bionoid Monster in the line of duty. Doctor Kenzo Igarashi, a man whose experiments had been responsible for the Bioron syndicate's existence, brought the man back to life as a cyborg detective, Jiban. Eventually, Madogarbo and Rhinonoid killed Jiban, who returned to life again as Perfect Jiban (basically the same design as the original, but with a blue-colored metal body and three new weapons). In the finale, Biolon destroyed Jiban's base and transformed Madogarbo into a false Jiban. Jiban defeated his duplicate and ultimately Gibanoid, the true form of Biolon's leader Doctor Giba. The victorious Jiban then learned that Mayumi Igarashi, the one civilian that knew his secret, had been his missing younger sister all along.
