Elder Bago, last of the Incas, gives the GiGi Armlet to Amazon for safekeeping while using his knowledge of Incan science and magic to perform a mystical "operation" on Daisuke, transforming him into the powerful "Kamen Rider Amazon" before he died.

Befriending the nephew and niece of Professor Kousaka, Amazon learns the nature of the GiGi Armlet as he defeats Gedon and then the Garander Empire.
