A Walden Group Power Raver, operated by Sylvia, attempts to stop Wujin
Power Ravers are walker-type piloted machines or automated robots that are designed for specific jobs, such as armed combat or construction, although some can perform in a multi-role platform. They often appear as huge humanoid machines reminiscent of mechas.
In the futuristic modern world of Asadal, the Walden Group is known as a major manufacturer and operator of Power Ravers.
