Giant monsters began to attack the world's
major cities, but one by one, these enormous
organisms began to disappear! Massive airborne
vessels, never before seen by man, begin to
converge with an enormous, spherical spacecraft
above Tokyo. From this "Mothership"
came the leader of an alien race, called the
Xiliens. He explained that his race had destroyed
these monsters, and also explained that the
world was in great danger from an asteroid called
Gorath. This celestial body could be destroyed,
if the world would accept their help and lend
the aid of their weapons against the meteor.
However, some humans did not trust the Xiliens
and began to seek their true intentions. It
was discovered that within the hull of the massive
Mothership, the monsters that had attacked Earth
were being contained! When their plans were
discovered, the Xiliens began to destroy the
Earth's populace yet again. An all-out invasion,
consisting of an array of monsters and an unfathomable
multitude of powerful craft, was unleashed on
a hapless planet.
In response, the humans released Godzilla from
his Antarctic tomb, for this creature was the
last hope for a dying world. The raging reptile
was led to Tokyo by Gotengo, a massive aerial
war-machine, and along the way, Godzilla defeated
wave after wave of enemy monsters. When the
Gotengo finally reached the Mothership, the
hull of the alien vessel was penetrated, and
the crew of the Gotengo journeyed deep into
the heart of the colossal craft. After a long
battle between Ozaki and the Xilien's leader,
the Mothership was set to self-destruct. The
humans escaped aboard the Gotengo as the entire
Mothership exploded, setting Tokyo ablaze and
killing everyone aboard. The Xiliens' plans
for invasion were finally put to a halt.
