Plot
Following the events of Godzilla: Planet of the Monsters, the Aratrum is unable to contact Haruo and the rest after their encounter with the original Godzilla. The Captain orders that if drones do not find survivors by forty-eight hours, the Aratrum will withdraw from Earth.

Haruo Sakaki is rescued by a native girl named Miana and has his wounds treated with a strange powder. She belongs to an indigenous tribe called the "Houtua", surviving descendants of humans. The Houtua recover Haruo's surviving team and hold them for questioning. Miana and her twin sister Maina use telepathy to communicate with their guests to understand their reasons for burning their lands.

After the Houtua realize the group was after Godzilla, the twins inform Haruo that their god was destroyed by Godzilla and left behind an egg. With an understanding that Haruo is waging war against Godzilla and not the Houtua, they are released, but the twins accompany them as both protective guides and observers. The group is attacked by a swarm of wormlike creatures, but they are able to fight them off with the twins' help. During the fight, Galu-Gu realizes that the twins' arrowheads are laced with "nanometal", a remnant of Mechagodzilla. 

They are then attacked by a pack of Servums, but Metphies arrives with some other survivors and drives them off.

​Galu-Gu explains that the nanotechnology that built Mechagodzilla somehow survived and in the past 20,000 years, it has steadily self-replicated and expanded itself. With this fact, the Bilusaludo tell Haruo and the rest that they can win against Godzilla with the nanometal, which prompts Haruo and the rest of the crew to remain on Earth and continue the original plan to defeat Godzilla. They manage to make contact with the Aratrum, which takes the few crew members who wished to leave and agrees to stay in orbit. Tracing the source of an energy signature they detected, they discover the nano-materials have rebuilt the former facility that held Mechagodzilla, which Galu-Gu dubs as "Mechagodzilla City".

The twins part ways, but warn Haruo that the nanometal is toxic; the Bilusaludo assure the group that the technology is harmless to them. The team soon discovers that even though Mechagodzilla was destroyed, half of its head survived and has reconstructed and expanded the original facility it was held in. Galu-Gu manages to gain access to Mechagodzilla's surviving brain and has it build all necessary materials for them to use in order to trap Godzilla within the city, then cover it with nanometal, before finishing it off with EMP harpoons.

​Godzilla awakens and quickly advances on the city, which forces Galu-Gu to sacrifice the city's defenses in order to divert power to finish building the harpoon. Haruo, Yuko, and Belu-be battle Godzilla with aerial Vulture suits in order to slow it down. The trio managed to hold Godzilla long enough for the city to complete its construction and proceed to lure Godzilla into the trap. Godzilla survives the attack and overheats the facility. Galu-Gu refuses to lose and decides to fuse with the nanometal.

While the remaining Bilusaludo embrace the fusion, the humans are appalled by it and escape the city. The three Vultures begin to fuse with their pilots, against Yuko's will. To Galu-Gu's bewilderment, the nanometal seems to have no effect on Haruo and fails to assimilate him. Metphies warns Haruo that if it is not stopped, Mechagodzilla City will consume the entire planet. Galu-Gu argues that in order to defeat Godzilla, they must become greater than humanity. Haruo is conflicted, but ultimately chooses to win the battle with his humanity intact. He destroys the command center, along with Galu-Gu, which deactivates the nanometal but sets Godzilla free, who proceeds to destroy the city. Haruo tends to Yuko, who is unable to wake from her comatose state, while the surviving humans hide in a cave with Metphies as everything burns around them.

In a post-credits scene that flashes back to an earlier scene, Metphies explains to Haruo that a monster, more powerful than Godzilla, destroyed his planet, and reveals that the monster's name is "Ghidorah"

"18 years after Godzilla 2000, I am glad to be back in the world of the new Godzilla which was opened by Shin Godzilla. This is the first animated film in the history of Godzilla, and I am excited to be able to take on the challenge while at the same time I feel it is a very big mission. I think this will be a Godzilla movie that you can’t possibly imagine. I expressed in music my own feelings about the characters and the overwhelming presence of Godzilla created by the two directors, Mr. Shizuno and Mr. Seshita." - Takayuki Hattori, Toho Press Notes
