College student Takeshi Hongo is abducted into terrorist organisation Shocker (Sacred Hegemony Of Cycle Kindred Evolutional Realm), at the hands of a cyborg Inhumanoid (Kaijin) known as the Bat. There, he undergoes painful reconstructive surgery, turning him into an Inhumanoid himself.
Takeshi Hongo is a man of extraordinary intellect, but his promising future is about to be maliciously snuffed out by and evil secret society known as Shocker. Reinvented against his will and transformed into a powerful experimental cyborg, Hongo will forever be known as Kamen Rider The First.
Bent on the destruction of the human race, the secret underground organization Shocker secretly planned to plunge the world into chaos. But they didn’t count on the revolt of both of their experimentally “reconstructed” human beings, the Kamen Riders. Two years after their first battle with Shocker, a 3rd Rider arises to confront them, known only as “Version 3.” The arrival of the third Kamen Rider will hurl the heroes into their most terrible battle yet and the fate of the world hangs in the balance.
