Talk:King Ghidorah (GtTHM)/@comment-11308450-20140911204427/@comment-25285745-20150419183745

The Heisei series and the Rebirth of Mothra trilogy do not take place in the same universe. In the Heisei continuity, Mothra left Earth in 1993 to destroy a meteor in 1999, but in Rebirth of Mothra, which is set in either 1996 or 1997, she is still on Earth and has been for years. Also in the Heisei series, Mothra's fairies are two identical twins called the Cosmos, but in the trilogy they are two sisters called the Elias that have another sister. Plus, in the Heisei continuity, King Ghidorah is the fusion of three Dorats and was killed in 1992 by Godzilla twice, yet in the Mothra trilogy, he is a member of a race of ancient space dragons and still very much alive.

So, there is absolutely no way the Heisei series and the Mothra trilogy are connected. "Grand King Ghidorah" is a nickname that I have no idea where it came from. All Japanese media explicitly refer to the 1998 King Ghidorah incarnation as just King Ghidorah or Cretaceous King Ghidorah. That's like saying the 1955 Godzilla is a separate character called "Gigantis" and that Godzilla Raids Again is somehow canon with the Heisei series.
