Premiering back in 1978, the Japanese live-action television series was produced by Toie Company under license from Marvel and lasted for 41 episodes. The series revolved around Takuya Yamashiro, played by Shinji Todō, a motorcycle racer who is given spider-like powers after an injection of blood from the last surviving person of the Planet Spider.
Like any self-respecting Spider-Man, Yamashiro can shoot webs, but what separates him from his American counterpart is the fact that he gets his own giant robot. I repeat, he gets his own giant robot.
Named Leopardon, the robot helps Yamashiro defeat a bevy of alien baddies. Toei’s experience with this would help lay the foundation for its Super Sentai franchise, which would eventually be adapted in the U.S. to become the Power Rangers.
