|~ Daisuke Yamamoto's Transformation|
Daisuke Yamamoto (山本 大介) is Kamen Rider Amazon, the titular character and main protagonist of Kamen Rider Amazon.
Daisuke Yamamoto was an young child who was raised in a village in the Amazon after his parents were killed in a plane crash. His life is changed when the Ten-Faced Demon Gorgos attacked and destroyed his adopted home village in search of the mystical Gigi Armlet, which would grant him the power to enslave the world if combined with his own Gaga Armlet. After being wounded by Gorgos, the village elder, Bagow, inserts the Gigi Armlet into him, which allows him to transform into the warrior Amazon. He goes to Japan to meet a professor who knew his father and battles Gorgos and his organization Geddon after they begin targeting Japan, becoming the new Champion of Justice.
GiGi Armlet (ギギの腕輪 Gigi no Udewa?) is a mysterious O-Part of the Incas that was created 120 years ago as one of two keys that would allow the user of the two to rule the world with Incan super science. The GiGi Armlet serves as Amazon's power source along with being the only thing keeping him alive. Grafted unto his left arm, Daisuke is originally unaware of the Armlet's true power until he found the Quipu that revealed it.
Condorer (コンドラー Kondorā?) is Amazon's belt. While not the means of Amazon's transformation like Riders before and after, it has other uses such as a grappling hook.
The Jungler (ジャングラー Jangurā?) is Amazon's motorcycle, built by Tōbei Tachibana based on design specs provided by Kōsaka from his journey into the Amazon. The Jungler is much more vibrant and exotic than Tōbei's previous creations, featuring "wings" on the back and a "mouth" and "eyes" on the front. In Kamen Rider Spirits, the Jungler has a hidden grapple cable and winch in the "mouth" of the bike used to scale high terrain.
