Godzilla Vs. Kong's Eiza González would be first in line to visit Hollow Earth
First introduced in Kong: Skull Island, the Hollow Earth theory is the idea that all of the titans plaguing and existing on Earth are originally from a separate world that exists at the center of the planet—what most people would call the core. It’s a theory that features prominently in Godzilla Vs. Kong, as Kong and a bunch of his human hangers on return to his ancestral home.
