>>23141461idk man, godzilla is big as fuck. I get the feeling you haven't seen too many G movies. He is depicted as an unstoppable, nearly unkillable terror that shrugs off mankind's best efforts at harming him.
think of it this way, an assault rifle or missile would fuck up most of the pokemon you mentioned. Godzilla doesn't even flinch. So you have to assume that he's got some thick enough skin that I can't really imagine any pokemon move really doing much damage
I included a pic of godzilla and every pokemon to scale for reference.
