depths of the ocean (though not before ejecting its human occupant to safety). Reiwa period (2017–2018) Mechagodzilla appears briefly in Godzilla: Planet of the Monsters, the first film in the anime trilogy. The mecha is designed and constructed by Humans and Bilusaludo - the latter one of two alien races who made contact with humans in an attempt to rescue them - as a countermeasure against Godzilla. But the mech is never activated as Godzilla attacked the construction facility forcing them to abandon it. Though not seen again, the mech is referenced several other times throughout the film. In Godzilla: City on the Edge of Battle, the second film in the trilogy, the remnants of Mechagodzilla's AI rebuild the facility it was created in by utilizing nanometal to help defeat Godzilla, aptly named "Mechagodzilla City". It also creates three battlesuits with flight capabilities called "Vultures". Haruo and his forces use the city as a base of operations to destroy Godzilla. When Mechagodzilla City begins assimilating its surroundings and living beings with its nanometal under the command of the Bilusaludo, and is predicted to assimilate the entire planet prompting Haruo to destroy its command center, giving Godzilla the opening to destroy it. In Godzilla: The Planet Eater, some nanometal survives within Yuko's body which Professor Martin extracts and applies to the last Vulture intending to rebuild civilization. Realizing this will only repeat the mistakes that prompted Godzilla's advent, endanger the Houtua and risk the return of Ghidorah, Harou takes Yuko and the last Vulture and flies all three towards Godzilla in a suicide charge to save the Houtua from mankind's mistakes. MonsterVerse (2021) Mechagodzilla was featured in the 2021 film Godzilla vs. Kong. Secretly built by Apex Cybernetics as an anti-Titan weapon and modeled after Godzilla, it is remotely piloted by Ren Serizawa via a telepathic link originating from a skull of Ghidorah's left head (acquired after it was torn off by Godzilla in Godzilla: King of the Monsters), though conventional energy sources prove insufficient to power it to full capacity. As Mechagodzilla is being built at a facility in Pensacola, Florida, Godzilla senses Ghidorah's presence whenever the mecha activates, which causes him to search for and eventually attack the facility. Due to the secrecy of the project, the public misinterprets this as Godzilla having gone rogue, resulting in Monarch and Apex taking Kong to the Hollow Earth in search of
