I’ve talked about this before, but I don’t think nations suffer wounds in the same way that humans do. It’s been canonically shown on several occasions that the nations themselves fight in their wars, and if their bodies took the same damages that mortal bodies do, most all of them would be walking around covered in scars at best, horribly disfigured at worst. (I know a lot of people like the idea that they’re all covered in scars, but if that’s the case then they’re all conveniently hidden from their faces and arms and any other skin we see in canon.) I made a post ages ago detailing how I interpret scars on nations, but briefly, I think scars are from things that would have killed them if they were human.
In short, I think that if the bodies of the nations took damage in the same way that human bodies do, the characters would look a LOT different.
