Giant Robo the Animation: The Day the Earth Stood Still

The story takes place in a future where humanity has achieved a new era of prosperity thanks to Dr. Shizuma's invention of the Shizuma Drive, a revolutionary renewable energy source. However, this peace is disrupted by Big Fire, a cabal seeking world domination, and the International Police Organisation dispatches a team of superpowered warriors and martial artists, including Daisaku Kusama, the master of Earth's most powerful robot, Giant Robo. Daisaku's past as the inheritor of Giant Robo is put to the test as the group clashes with Big Fire over control of an abnormal Shizuma Drive. The story draws inspiration from various genres, including opera, kung-fu cinema, and classic mecha anime.
