Kamen Rider Black RX (Decade)

Kotaro Minami is a man who fights the Crisis Empire as Kamen Rider Black RX in the RX World, able to become either Robo Rider, or Bio Rider. 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 convinces him that Tsukasa 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.
