Godzilla: The Planet Eater (ゴジラ星を喰う者, Gojira Hoshi wo Kū-mono)[b] is a 2018 Japanese computer-animated kaiju film directed by Kōbun Shizuno and Hiroyuki Seshita.

The film follows the struggles of humanity, their extraterrestrial allies, and Godzilla as they battle to survive against King Ghidorah.

Following the destruction of Mechagodzilla City,[d] the remaining Bilusaludo on the Aratrum demand justice for Haruo destroying what they saw as necessary to defeat Godzilla.

Ghidorah manifests as a shadow on Earth and partially through singularities, devouring Metphies's followers and destroying the Aratrum.

Metphies's people devoted themselves to Ghidorah since learning that their universe is finite and fated to destruction, having offered planets for the monster to feed on.

Haruo breaks free and cracks Metphies' amulet, causing Ghidorah to become affected by Earth's physics, and as such being ultimately defeated by Godzilla.

Dr. Martin gets the last remaining Vulture mech working, having discovered how to use Mechagodzilla's nanometal in Yuko's body as a tool to rebuild civilization as it was.

Haruo's right eye stings, hearing Metphies's voice saying that this turn of events would ensure Ghidorah's eventual return to their reality.

This prevents Ghidorah from returning as the Houtua continue to live alongside Godzilla; treating the kaiju like a natural disaster to be respected and avoided but not warred with.

Years later, Maina, showing signs of advancing age, watches a group of children conduct a ritual honoring Haruo, placing knotted strings representing their fears into a fire under a wooden effigy of a Vulture mech.

Joshua Meyer from /Film stated "Rather than revert to a big dumb monster movie, The Planet Eater is able to balance its kaiju action with life-and-death concerns while wrapping up threads of character drama woven through the trilogy as a whole.

"[15] Daniel Kurland from Den of Geek awarded the film 3 stars out of 5, feeling the animation was "lackluster" with "Regrettable" CG effects and Hattori's score was "questionable."
