Kamen Rider ZO is a 1993 Japanese tokusatsu superhero film. It was the first Kamen Rider movie to be released in the Heisei period, and it was also the first film for the Kamen Rider Series. The movie follows two monsters, ZO and J (played by Toshiki Kashu and Shiro Izumi respectively), as they battle against an evil organization known as Neo-Shocker in order to save Earth from destruction. The movie features several special effects sequences, including giant monster battles, motorcycle stunts, and martial arts fights. The film also featured a cameo appearance by Hayato Ichimonji (portrayed by Takeshi Sasaki), who would later become Kamen Rider Black RX in the television series of the same name.
