Long ago on Planet Vegeta there were two races: the Saiyans and the Tsufurus. Being much taller and stronger, the Saiyans quickly destroyed the Tsufurus and took over their technology. One Tsufuru named Dr. Raichi, however, created a computer that absorbed his hatred of the Saiyans – and this computer survived the attack by leaving the planet. Now, years later, it has acquired enough strength to create Ghost Warriors, for the sole purpose of destroying the remaining Saiyans on Earth. Will Goku and the other Z-fighters be able to stop this powerful machine from extracting its revenge?
