Spectreman was sent to Earth to save humanity from destruction caused by pollution, but during his first mission, he encounters a giant monster that emerged from the waters of Tokyo Bay. In reality, the creature was the work of two aliens: the simian Gori—whose intelligence surpassed that of any human being—and their assistant, Karas, who intended to take over Earth by eliminating humanity.
