Kamen Rider Amazon (1974)

“Welcome to the Jungle!”

Led by the terrible Ten-Faced Demon, the ferocious forces of Gedon burn through the rainforest in search of the Gigi Armlet—an ancient Incan artifact of untold power! In a last-ditch effort to safeguard the relic, it is grafted onto the body of an orphan simply known as Amazon. Now imbued with superhuman abilities, the feral hero travels to Japan in order to rip apart Gedon’s plans for world domination! However, when a young boy gets caught up in the battle, he realizes that Amazon’s fighting form looks kind of like a rider... A Kamen Rider!
