Luckily, Godzilla and King Kong put aside their differences and join forces to vanquish Mechagodzilla before it could wreak havoc past Hong Kong.
In any case, Godzilla vs. Kong is out now, so people know how Mechagodzilla precisely fits into the cinematic picture.

Within the MonsterVerse continuity, the mechanical Titan was built by Apex Cybernetics and operated by Ren Serizawa using a neural uplink through the skull of one of Ghidorah’s heads.
