WARNING: The following contains spoilers for Godzilla: King of the Monsters, in theaters now.
With the rise of the Titans in Godzilla: King of the Monsters, humanity risks losing its role as the top of the food chain. The basic structure of the world as we know it is poised to change irrevocably by the influence of the Titans roaming the planet. If Monarch can't help contain the Titans being commanded by pack leader Ghidorah, then humanity is at risk of being wiped out. That's what happens when we come up against giant monsters.
But a frequent aspect of the story referenced by the scientists at Monarch hints at humanity's true potential. They could be the same kind of apex predator that Ghidorah and Godzilla have proven to be, capable of saving -- or destroying -- the world.
The Pack Leader
During King of the Monsters, the eco-terrorist Alan Jonah (Charles Dance) and his men help unleash King Ghidorah from his frozen slumber in Antarctica. The creature quickly helps reawaken all of the other Titans around the world. This leads to rampant destruction and devastation, as the giant monsters quickly wipe out any area they're in. This includes rural places, but major cities as well. By virtue of being the most powerful one of them all, the other Titans recognize Ghidorah as the "pack leader" and follow his will. It's established that his influence is why they're turning on the planet, because Ghidorah wants to irrevocably change the planet, potentially wiping out humanity.
Jonah is fine with this result. Having lived as a soldier his whole life, he's seen the worst humanity has to offer. More than anyone else, he's up for a cosmic do-over. Without the Titans, humanity has supplanted them as the dominant species on the planet. Our influence has directly affected the planet in a decidedly negative way. Emma Russell (Vera Farmiga) hypothesizes that humanity will soon be responsible for the destruction of the planet if we're not put in check. This is what she believes the Titans were created to do, serving as the protectors of the planet. Although she believes there may be a way for humanity to coexist with the Titans, it has to be in a world where people aren't making all the decisions. The Titans can usher life back into the planet, whereas humanity has left nothing but death.
At the end of the film, her theory is proven at least partially correct. The radioactive nature of the Titans is shown to be actively improving life on Earth. Forests regrow. Sealife swells. The world has begun to heal itself thanks to the Titans. But humanity has not become some docile presence in the shadow of the Titans, and that could prove to be disastrous, either for us or for the Titans.
It's noted throughout the film that the only Titans who don't give in to the commands of the "pack leader" Ghidorah are Godzilla and Mothra. This is because they are also "apex predators," the most powerful of their kind. It's hinted that the same may apply to Kong on Skull Island. But there's another Apex Predator who doesn't cow to Ghidorah: humans. What people lack in radioactive powers or massive size, they make up for in sheer numbers and potential. It was our acts that reawakened the Titans in the first place, and it's shown that humanity possesses the capabilities to stand up to Titans. Humans actively combat Ghidorah alongside Godzilla, buying time for him to heal and even using a nuke to speed up the process.
Moreover, the creation of the Oxygen Bomb suggests that humanity is closer than ever to actually be able to stop a Titan on our own if need be. Although it failed to slow down the alien Ghidorah, it almost proved fatal for Godzilla. Our ingenuity is what elevates us above most animals, and it could be what makes us a potential equal to the Titans. But the question is whether or not the Titans will ever realize that.
King of the Monsters establishes the rivalry between Godzilla and Ghidorah is for dominance on a global scale. What happens if Godzilla ever decides to wrest control away from us? Would he see us as the threat we could be? Remember, the "pack leader" commands the rest of the Titans. Does that mean that humanity could eventually find a way to control the Titans, or least coexist with them?
Even with Ghidorah dead, another massive duel is brewing. The closing moments of the film reveal that activity on Skull Island suggests that some Titans see Kong as the new pack leader. Godzilla is set to battle Kong, and the battle could be incredibly destructive, but humanity could be just as deadly and may have to be if they want to survive that grudge match.
