Takeshi Hongo was once an ordinary college student and motorcycle enthusiast until the day he was abducted by a secret evil organisation called Shocker. Taken to their underground labs, Takeshi became a victim of Shocker's Super Soldier program and was transformed into a cyborg against his will. But before they could complete his Brainwashing, Takeshi was set free by the Heroic Sacrifice of an unwilling Shocker scientist named Professor Midorikawa. Now Takeshi uses his physical and mental enhancements to fight against Shocker and prevent another tragedy like his, re-christening himself as the Kamen Rider.
