As Michael Dougherty tells Collider, Mothra isn’t quite like the rest of the creatures that appear in Godzilla: King of the Monsters.
While the rest of the titans are basically just monsters that are really good at stepping on buildings or biting holes in each other, Mothra is different.
She’s the only one of the creatures that has been historically presented as entirely good, and Michael Dougherty says was the reason she could be handled differently, which was solution to the daunting problem.
