The possibility of Gojira himself being the main villain of Godzilla: King of the Monsters’ final scene. The alpha Titan has only operated as a protector thus far in the MonsterVerse, but the Godzilla vs. Kong trailer has left a strong implication that he’ll be going down a different path when it comes time for his second big screen showdown with King Kong.
Warner Bros. has finally released the Godzilla vs. Kong, and unlike the full trailers for the last two Godzilla movies, this one shows quite a bit of the two central Titans coming to blows. Plus, it previews what the story has to offer; it seems that Kong will apparently be captured by Monarch, who for some reason believes that the world needs him. While still a prisoner, Kong will be attacked by Godzilla, with whom he shares a rivalry that dates back thousands of years to their ancestors. Based on events that take place in the trailer, it appears that the instigator of the conflict is really Godzilla. According to Kyle Chandler’s Mark Russell, Godzilla is hurting people for unknown reasons. The trailer also reveals that Godzilla has been launching attacks all over the world.
Though it hasn’t been outright confirmed, the Godzilla vs. Kong trailer is certainly leaving the impression on viewers that Godzilla is the movie’s villain. Whether he actually is or not, a villainous turn for his character was in fact foreshadowed in King of the Monsters. After Rodan and the other Titans bowed down to their new alpha, Dr. Stanton (Bradley Whitford) remarked that he was glad Godzilla is “on our side”. This prompted an unconvinced Dr. Chen (Zhang Ziyi) to add, “for now,” because Godzilla isn't an inherently good character; sometimes he turns on humanity.
Dr. Chen’s comment indicated that even though Godzilla had just succeeded in saving the world for the second time in the MonsterVerse, there are still humans out there that doubt him. It also felt like it was the movie’s way of saying that Godzilla defeating King Ghidorah doesn’t make him humanity’s friend. Godzilla may have saved them, but that doesn’t necessarily mean he can be trusted. That makes sense, given that Godzilla is a monster with his own motives and goals. In both Godzilla and Godzilla: King of the Monsters, his interests happened to align with the humans’, but that may not always be the case. Dr. Chen’s remark reminded audiences that the MonsterVerse’s Godzilla could always turn against the humans in the future, depending on the circumstances.
It looks like that moment is already happening, as the humans have finally found themselves on opposite sides with Godzilla. That’s obviously why they’re looking to Kong to be their new hero. Of course, as things often are with Godzilla, it’s likely that their situation with him isn’t so black-and-white. Godzilla may be attacking them, but it wouldn’t be surprising if the monster has good reasons for what he’s doing, or if Mechagodzilla is posing as the real thing. If this really is Godzilla acting of his own free will, it may be that he’s only targeting people with ill intentions toward the Titans in Godzilla vs. Kong.
