What makes a personified force of nature?
You guys may have heard this term before. I often see critics talking about it in some Studio Ghibli's movies where the reviewers say that the antagonist is the force of nature itself.
But I also see stories where people say that the force of nature is personified.
It is said that Chigur from No Country for Old Men is a force of nature antagonist. It is said that some antagonist robots from Isaac Asimov's stories are forces of nature. It is also said that the Chandrian from the Kingskiller chronicles is a force of nature antagonist. I got these few examples which I dont know if they are pure opinion-based visions or not.
My question cannot be more simplified than this: What makes a personified force of nature?
This question may involve these ones to incite imagination in your answer: He/she should be antagonist all the time or not? What kind of person he/she would be? Why he/she would act the way he acts? How powerful should he/she be to be considered "a force of nature"? I know that the question sounds simple and that the answers might be huge, but this is a topic I would like to see being answered with different visions.
I think that the core of the question is in the word "MAKES." It makes the question to be more specific and have some good answers for it too.
PS: I'm new to SE and I dont know if my question is good or clear enough. I shall be reading your feedback in the comments if you guys need anything from my question.
