Kazuya Oki volunteers to undergo cybernetic surgery in the International Space Development Program in the United States in order to become an astronaut who can survive in outer space without the need for a bulky external suit. After a successful operation, he is given the codename "Super-1". Before he can depart for space, however, the base where he received his operation is attacked by the Dogma Kingdom. Only Kazuya is able to escape. Determined to avenge the deaths of the scientists, he returns to Japan and is trained by a martial arts expert, Master Genkai. With this knowledge, he is able to transform into the powerful Kamen Rider Super-1. His design is of a hornet. At the half of the series, Super-1 finally topples the Dogma Kingdom, only to encounter another evil group called the Jin Dogma. Ultimately, Kazuya defeats Jin Dogma, allowing Japan to exist in peace. He then finally fulfills his childhood dream and ventures into outer space with the help of a new team of scientists. Returning to Earth, Kazuya would later ally himself with the past Kamen Riders, and along with Kamen Rider V3 and Riderman, would help to convince Ryo Murasame, the 10th Rider Kamen Rider ZX, to join their side.
