The Rock Lord: Power of Hope

The Rock Lord toys weren't successful, but they would get three series of releases. There's a lot of stuff online about unreleased Rock Lord's play sets. Music for the film was done by Hoyt Curtin, who provided the music for the TV show. They did create some other Go-Bots material, including a video game, challenge of the Go-Bot on the Mobius Strip. It was published by Reactor for the Amstrad CPC, the ZX Spectrum, and the Commodore 64.
