|This article is about a/an alternate reality/A.R. World (another rider's world) in Kamen Rider Decade.|
The World of Kamen Rider Amazon (仮面ライダーアマゾンの世界 Kamen Raidā Amazon no Sekai?) is an alternate reality where a version of Kamen Rider Amazon takes place. By the time Decade arrives, he finds the world is under Dai-Shocker's control as they eliminate any resistance. As a result, the people do not trust each other, as they cannot tell who is and who is not aligned with Dai-Shocker. The backdrop used to arrive in this world depicts the Amazon Rainforest with Amazon in the middle of it. Within this A.R. World, Tsukasa wears the attire of a baseball player. Daiki's treasure in this world is the GaGa Armlet.
