Doctor Nazo is a mysterious alien scientist who aims to conquer planet Earth through various criminal and destructive activities. The heroes who go against Nazo and his henchmen are Doctor Yamatone and his team of the Pearl Research Institute, but they are usually unable to defeat the evil mastermind by themselves. Thankfully they have the sworn protection of the Golden Bat, a skull-faced superhero from the sunken city of Atlantis, awoken from a 10,000 year-long sleep.
