The Dummy Inhumanoids are a series of copies of past Dopants and Greeed fought by the Kamen Riders and antagonists in the Kamen Rider 40th anniversary movie Kamen Rider x Kamen Rider Fourze & OOO: Movie War Mega Max.
They were sent to attack Kamen Rider OOO while Fourze obtained the four Astroswitches and three Core Medals. They initially overwhelmed OOO until Fourze claimed all the Astroswitches and Core Medals. The two Riders then inserted them into their Drivers and freed the seven Legendary Riders. With assistance from Kamen Rider Aqua, the seven Legendary Kamen Riders fought and defeated the eight Dummy Inhumanoids.
