Kamen Rider Amazon

A plane crashes in the Amazon rainforest, leaving young Daisuke Yamamoto stranded without his parents. Soon adopted by a native tribe, Yamamoto becomes a modern day Tarzan, living off the land. However, Yamamoto's idyllic existence is cut short when Gorgos, the Ten Faced Demon, massacres his village, slaughtering everyone except himself. Gorgos is seeking the powerful "GiGi Bracelet", which gives the bearer fantastic power. A witch doctor in the village, sensing the trouble, retrieves the bracelet and gives it to Yamamoto for safekeeping. He then uses his knowledge of Incan science and magic to perform a mystical "operation" on Yamamoto, transforming him into the powerful "Kamen Rider Amazon."

Yamamoto then travels to Japan, where he meets a professor who knew his father. Soon, the minions of Gorgos catch up to Yamamoto, murdering the professor. During the process, Yamamoto saves a young boy named Masahiko, who obliges to teach Amazon (as Masahiko dubs Yamamoto) the ways of the world. Amazon soon receives the "Jungler", his motorcycle. Amazon also partners up with Mogura-Juujin, a former henchman of Gorgos, after Amazon rescues him from execution. Together, the two of them face off against Gorgos himself, eventually destroying him in an atomic blast. However, the "GaGa Bracelet", the counterpart of the GiGi, then falls into the hands of the Garander Empire, led by the ruthless Emperor Zero. Amazon continues his fight against evil, eventually toppling the Garander empire and retrieving both bracelets.

His mission now complete, Amazon ventures off to travel the world.
