Funky aliens from Planet X borrow Godzilla and Rodan to battle King Ghidorah; the local bully on the block who’s been ravaging their planet. All is not what it seems though when the traitorous bastards brainwash the three Kaiju bad boys and turn them on Earth. Queue space heroes Glenn and Fuji to save the day.

 

The outer space themes that became so prevalent in later Godzilla flicks were first introduced in this sixth entry in the series. Nick Adams, who plays swaggering astronaught Glenn, is a hoot as the hotshot who helps save the day.  Released in America as MONSTER ZERO.
