It's Mechagodzilla! Godzilla's robotic counterpart appears in Godzilla vs. Kong — a "twist" that was teased in international trailers — and it's revealed that the King of the Monsters was going on a rampage in the first place because Apex Cybernetics was building a monstrous machine that would rival his power. It takes the combined might of Godzilla and Kong (but mostly Kong, to be honest) to defeat Mechagodzilla. Mechagodzilla has appeared in five previous live-action Godzilla movies and, briefly, in an anime movie, too. His first appearance was in 1974's Godzilla vs. Mechagodzilla... six years after the film debut of Mechani-Kong.
