SPOILER WARNING: This section may contain major plot and/or ending details. Proceed at your own discretion.
An unknown fast-moving monster is detected somewhere in the Pacific Ocean, and is swimming towards Honolulu, Hawaii. A character named Lucy Casprell enters a hotel room at Honolulu. Then, Gigan wakes up and ends up in Kumonga's turf in the Grand Canyon, Arizona. Kumonga starts covering Gigan in webbing until Gigan cuts off one of Kumonga's limbs. Kumonga hides, and Gigan sets the webbing aflame and flies away.Then, an international Megazoology conference is held. Dr. Kenji Ando, a founder of Megazoology, speaks at the meeting. He says that Megazoology is the study of daikaiju. He then shows a slideshow about monsters, showing some information about them, such as their whereabouts. Anguirus is in the border of Mexico, Titanosaurus is in the ocean, most footage of Mothra has disappeared, Rodan was last seen above Canada, and then he shows others that are unaccounted for, like Battra, Hedorah, and SpaceGodzilla. Right after, doctor Ando shows the fire in Arizona, which is thought to have been caused by Gigan and Kumonga just hours before. There are many other kaiju that have not been discovered, said the doctor. At the same time, Zilla arrives at Honolulu, sending the people at the conference to panic. Lucy takes a camera and plans to film Zilla, but almost gets eaten by the monster. Right then, Steven Woods and his troops shoot at Zilla with guns, which seem to drive it away a little. Steven then tells an officer named Chavez to take Lucy to the hotel's shelter. Steven calls for weapons, and asks the name of this monster. The connection to the other officer gets glitchy, and as he is telling Steven that Godzilla is approaching, it is communicated as the monster's name being Zilla. Just then, a blue atomic breath is shot at Zilla. The troops turn around and see Godzilla approaching them.
