Kotaro Minami (南 光太郎 Minami Kōtarō) is a man who fights the Crisis Empire as Kamen Rider Black RX (仮面ライダーブラックRX Kamen Raidā Burakku Āru Ekkusu?), able to become either Robo Rider (ロボライダー Robo Raidā?), or Bio Rider (バイオライダー Baio Raidā?). However, with Dai-Shocker appearing in his world, he finds himself outmatched by the new monsters while searching for his friend Joe the Haze. Natsumi Hikari convinces him that Tsukasa Kadoya is not the Destroyer of Worlds that he heard about. Though he eventually learns of Joe's fate, Kotaro is not saddened as his friend would be with him in spirit.

Tetsuo Kurata (倉田 てつを Kurata Tetsuo?) reprises his role as Kotaro Minami from Black RX.
