The M Space Hunter Nebula Aliens are a hostile species whose natural appearance resembles a huge cockroach. They evolved within the ruins of a former humanoid civilization which once dominated their homeworld, but has since driven itself to extinction via massive environmental pollution, allowing the insectoid aliens to take over.
They once attempted to invade Earth by controlling the giant monsters known as Gigan and King Ghidorah; but were defeated by Godzilla and Anguirus. Strangely, they also seem to have become allies of Earth's oceanic civilization of the Seatopians, lending Gigan to them to assist their own monster, Megalon in their war against the surface world.
