When we start the conversation about the protagonist and the antagonist, some writers instantly jump to the conclusion that we are referring to a good-guy-vs-bad-guy story.
One might ask, "What if I don't have a villain in my story?"
My response: "Not all stories have villains. But all stories have characters striving towards a goal of some sort… and there is always something getting in the way."
I dove deeper into this idea in a previous post, highlighting that the role of the antagonist in a story is to get in the way of the protagonist achieving those goals, whatever those goals happen to be. But your protagonist is not necessarily the good guy of the story. And the antagonist is not necessarily another character. The good-guy-vs-bad-guy concept is one of many protagonist/antagonist pairings that might exist.
It's time to take a dive into the different types of antagonists found in stories. And not all of them are characters. We'll be looking at the classic good-guy-vs-bad-guy trope, but we're also going to dive into man-vs-nature and man-vs-self.
