Invasion of Astro-Monster/Godzilla vs. Monster ZeroAliens from Planet X borrow our monsters for a little extermination project, but they've got something else up their sleeves: world domination! Using mind-control technology, these vinyl-and-sunglasses wearing spacemen turn Godzilla, Rodan and King Ghidorah loose in Japan, demanding Earth's surrender! It's up to American astronaut F. Glenn, his galaxy-trotting buddy Fuji, and nerdy inventor Tetsuo to break the aliens' hold on the monsters and save our planet from certain doom.
