What do you think the “colossal, undiscovered threat” will be in the next movie?

Hey everyone!

One of the most intriguing bits of information that we’ve gotten from the new synopsis for the next MonsterVerse movie is that Godzilla and Kong will team up against a “colossal, undiscovered threat hidden within our world.” What do you think this could mean? If you ask me, it sounds like the new threat will be an original monster that lives in the Hollow Earth that threatens both humanity and the two Titans. Who knows, it might even be that flying Godzilla-like monster that was shown in the GVK artbook.
