1992: People from the future dubbed “Futurians” come to warn Japan about their destruction, blaming it on Godzilla. In order to prevent Japan from being destroyed, they travel back to 1944 and replace that Gojirasaurus with Dorats. The people of Japan find out that the Futurians are actually trying to destroy their country by replacing the future Godzilla with Dorats. The Dorats mutate into King Ghidorah, as he attacks Japan. Luckily, a rebel group of Futurians secretly move the Gojirasaurus into the sea, where he is mutated once more, and comes to defeat King Ghidorah.

A race of aliens called the Xiellians come to stop all of the monsters from attacking, and to warn them about a meteor heading towards Earth.
