The plot starts when a business man name Nakamura encounters a mysterious flying man named Alpha. Alpha tells Nakamura that an evil scientist named Dr. Bomb is planning to set an "End the World" weapon. Then Alpha gives Nakamura an odd metal rod which turns him into Bravoman, a bionic superhero who possesses telescopic limbs which can be used as weapons against Dr. Bomb's henchmen. The game takes a light and humorous approach to an otherwise trite theme, by using a lot of humorous elements, both graphics, plot and sound-wise, usually ridiculing or parodying stereotypical elements of Japanese tokusatsu and videogames, in a manner similar to the Konami game series Parodius.
