You're right, I guess I shouldn't assume that. It's just that Kong has pretty much always been portrayed as a sympathetic monster, so it's hard to imagine that they'd make him malevolent/destructive enough to set off LegendaryGoji's MUTO-sense and prompt a battle. There's also the fact that he's "our" giant monster, an American creation, so it's hard to believe an American film series would make the "domestic" monster the villain and the "imported" monster the hero. (Then again, the Japanese did just that in King Kong vs. Godzilla, but then, Godzilla had already been the villain in both his prior appearances, so it's not quite the same.)
