It is revealed in flashback that Fin Fang Foom is an alien being from the world of Kakaranathara (also known as Maklu IV) in the Maklu star-system of the Greater Magellanic Cloud. The aliens arrive on Earth in ancient China, intending to conquer the planet. Using their natural shapeshifting powers to mimic human form, the aliens infiltrate human society to study it before beginning their conquest. Foom, the navigator, is the exception and, acting as a reserve, is placed in a tomb in a catatonic state.
