Prince of Space
“Yusei Oji,” aka “Starman”

When aliens from the barren rock planet Krankor attack Earth, only the curiously costumed Prince of Space “(Wally the shoeshine boy in disguise) and his trusty exhaust-spewing rocketship can save the world – or at least Japan – from total conquest by the evil Phantom and his beak-nosed minions. Since conventional space weapons cannot harm the spring Prince of Space, the Phantom engages in a kidnapping scheme involving a cadre of international scientists.

Invasion of the Neptune Men
“Uchu Kaisoku-sen”

In another case of galactic conquest, clunky metallic aliens from the planet Neptune invade Earth – or at least, a quaint field in rural Japan – only to have their efforts thwarted by caffeinated superhero Space Chief (venerable action hero Sonny Chiba, Kill Bill, Vol. 1 and The Streetfighter), who travels from one head-scratching situation to another in his space car, when not befriending a group of geeky boys.
