The World of OOO (オーズの世界 Ōzu no Sekai) is the version of reality where Kamen Rider OOO takes place. The backdrop used to arrive in this world shows a diverse animal kingdom representing the Core Medals: including a lion, tiger, and a cheetah. Tsukasa Kadoya takes the role of Ankh in this world to the point of inheriting his distinctive red hairstyle and clothes. Kamen Rider Decade: World of OOO

This world's setting appears to match up with the timeframe following the TV series as well as Movie War Mega Max since Eiji Hino transforms into Kamen Rider OOO while Ankh is absent.
