Mechagodzilla was featured in the 2021 film ''[[Godzilla vs. Kong]]''.<ref>{{cite web|url=https://screenrant.com/mechagodzilla-design-look-godzilla-vs-kong-comparison-differences/|title=How Mechagodzilla's Design In Godzilla vs Kong Compares To Past Versions|first=Nicholas|last=Raymond|work=Screen Rant|date=April 6, 2021|access-date=March 29, 2022|url-status=live|archive-date=March 29, 2022|archive-url=https://web.archive.org/web/20220329190147/https://screenrant.com/mechagodzilla-design-look-godzilla-vs-kong-comparison-differences/}}</ref> Secretly built by Apex Cybernetics as an anti-Titan weapon, it is designed to wipe out the Titans and replace [[Godzilla (Monsterverse)|Godzilla]], remotely piloted by Ren Serizawa via a [[Telepathy|telepathic]] link originating from a skull of [[King Ghidorah|Ghidorah]]'s left head (acquired after it was torn off by Godzilla in ''[[Godzilla: King of the Monsters (2019 film)|Godzilla: King of the Monsters]]'' prior), 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 [[King Kong|Kong]] to the [[Hollow Earth]] in search of an energy source to confront Godzilla with; simultaneously, Apex covertly plans to use it to power Mechagodzilla, now housed within [[Victoria Peak]]. Godzilla and Kong clash en route to the Hollow Earth in the [[Tasman Sea]], but ultimately the team finds and retrieves the power source, in the form of "Hollow Earth Energy".

After Godzilla and Kong fight a second time in [[Hong Kong]], Serizawa charges the mechanized titan with the untested Hollow Earth's energies, upon pressure from Apex Cybernetics' [[Chief executive officer|CEO]] Walter Simmons. However, the process unexpectedly allows Ghidorah's mind to possess Mechagodzilla, who then kills both Simmons and Serizawa, goes on a rampage in the city, and faces Godzilla. Godzilla is easily overwhelmed, and is nearly killed before Kong joins the battle. Kong's axe initially proves ineffective against Mechagodzilla, as its energy was depleted after battling Godzilla. As Mechagodzilla maintains the upper hand, Josh Valentine tampers with its control panel via alcohol spillage, stalling it long enough for Godzilla to supercharge Kong's axe with his atomic breath. Kong then uses his fully powered axe to dismember Mechagodzilla's limbs, and finishes it off by tearing off its head.
