The next Godzilla x Kong film is now in production, and the team has given us a teaser.
It shows a Monarch's response room with an alert of a Titan sighting in one of the Monitors, before it goes to give us the title: Godzilla x Kong "Supernova".
Options: either is Gigan, Orga, or the Alpha that force Ghidorah to migrate to Earth - betcha they'll call it "Gorath", the latter, while been introduced as a drifting planet in the original 1962 film of the same name, in recent Godzilla media it was portrayed or hinted to be a monster.
In Godzilla Final Wars, it was the energy sphere Monster X/Keiser Ghidorah comes to Earth in, while in the prequel novels of Godzilla Planet of Monsters, Gorath, was is another threat the Earth alien alliance had to deal with and hinted to be a monster, as it change direction at will rather than been influenced by the gravity of the other planets. Godzilla proceeded to destroy Gorath in the same matter he fired at Ghidorah when arriving in Final Wars; this forced the Earth Alliance to abandon all plans to settle on Lunar and Martian colonies and go with the Spaceships after seeing the Big Gs potential of reach.
