Once a normal man, Takeshi Hongo was kidnapped by the evil terrorist group known as Shocker and turned in a deadly cyborg. But before Shocker could turn him into a mindless slave, he escaped with help of a scientist who betrayed Shocker. Now whenever Shocker attacks Japan, Takeshi uses his Typhoon Belt to become the cyborg superhero Kamen Rider, a hero almost as beloved by Japan as Ultraman himself for protecting them against Shocker's army of cyborg monsters.
