Lastly, Godzilla is known for his near-invulnerability thanks to his skin being able to resist artillery shells and blows from other giant monsters. However, a material able to resist missiles would have to be incredibly dense. After all, bomb shelters wouldn’t be nearly as effective if their walls were as thin as a piece of wood. Because of this I question as to how Godzilla would be able to effectively move unless the material that composes his skin is also somehow flexible enough to allow him to move without also breaking apart whenever he bends his knees.
