Voyage Into Space (1970)

Plot

Earth faces a grave threat from the interstellar terrorist organization known as Big Fire, led by the sinister Emperor Guillotine, who operates from a vibrant spaceship concealed deep in the ocean. Their sinister goal is to capture scientists and create monstrous soldiers for domination. Young Daisaku Kusama and Unicorn agent Jūrō Minami are shipwrecked after an assault by a sea creature and soon find themselves prisoners of Big Fire. They escape with the help of scientist Lucius Guardian, who provides them with a control device for a Pharaoh-like robot. Tragically, Guardian is killed activating a bomb, but the explosion awakens the robot, now loyal to Daisaku.
