tho I've also seen ppl say jc isn't an antagonist bc he's not completely evil and there are other bad guys but that's just not true from a literary perspective. an antagonist is, objectively, anyone who opposes the protagonist, which IS his role for much of the story. and there can be multiple of them in a work, they don't need to be on the same level of opposition or aligned at all. a school bully and a megalomaniac who wants to conquer the world are both antagonists
