Takeshi Hongo (played by Hiroshi Fujioka) is a brilliant biochemistry student and a Grand Prix-class motorcyclist with an IQ of 600 who is captured by Shocker. They transform him into a grasshopper-like cyborg, intending to make him their ultimate weapon. However, just before Shocker can complete the mind-control procedure, Hongo escapes with his sanity and moral conscience intact. Now possessing incredible powers, Takeshi Hongo swears to use his abilities to destroy Shocker and fight for humanity's freedom. As the "Masked Rider," Hongo rides his super-powered motorcycle, the Cyclone, and uses his super-speed, super-strength, and finishing techniques like the "Rider Jump" and "Rider Kick" to battle Shocker's monsters.
