I want to see these two behemoths
try to be mind controlled or lured by humans, only for the plan to fail miserably. Imagine King Kong trying to be captured, jets and helicopters flying everywhere on the island as tanks roll up, we get one amazing battle as the missiles from the jets don't work (showing Kong has grown). It would look badass as fuck! Maybe the humans try to put Godzilla down or try to get him to go away due to the destruction caused in Godzilla KOTM, but in this military assault Godzilla would retaliate unexpectedly, and the audience would know Godzilla fights only to preserve his life and protect himself, not because he's a villain. As long as we see the humans try to lure these 300+ ft tall gods together only to fail resulting in them encountering each other and battling it out (once in Skull Island and another in man's dominion be it New York or Tokyo so it resembles this cover:
)
Then that would be amazing! I mean they're both gigantic godly monsters, they shouldn't be taken under control. If anything man's actions should result in his very punishment. I want to see the tagline of the film follow this picture:
