Plot

The Nebulans, a race of cockroach-like aliens from a planet in M Space Hunter Nebula, plot to take over the Earth, as their home planet has been destroyed by pollution from another race native to the planet, which destroyed itself in the process. To carry out their plans in secret, they disguise themselves using skin suits based on deceased humans, and build World Children's Land, a theme park which serves as a disguise for their base of operations, centered inside a statue of Godzilla called the Godzilla Tower. They also have King Ghidorah and Gigan at their disposal, guiding the monsters using Action Signal Tapes, which broadcast a frequency that instructs them on what to do. The aliens plan to use their monsters to wipe out human civilisation.
