Daisuke Yamamoto (A.R. World)

Daisuke Yamamoto, known only as "Amazon" is a man from the Amazon Rainforest who traveled across the world to find a place that he could call home, eventually arriving in Japan where he fights Geddon as Kamen Rider Amazon. Though disillusioned after Masahiko used him to get the GiGi Armlet, Amazon regains his trust in humanity when the boy returns the armlet, finding his place by the Okamura. Afterwards, he aids Decade in battle against Apollo Geist and Llumu Qhimil, forcing Apollo Geist into retreat with his Dai Setsudan and destroying Llumu with his Super Dai Setsudan after Decade equipped him with the GaGa Armlet.
