To write compelling fiction, the writer must think in terms of a beginning, a middle, and an end with a defining theme. A main character (protagonist) with a goal must drive the story/plot. Each other character should be a subplot which crisscrosses the plot. They must reflect the theme, and in some way, interact with the main character. The character who opposes the main character can be a antagonist or a villain (represents pure evil with no redeeming characteristics). This character must be seeking the same goal as the main character, but for a different outcome. The stronger the antagonist or villain is, the more powerful the main character becomes and the more compelling the story becomes. In the interaction between the main character and the antagonist, the main character must show a transformation arc, which terminates at the end of the story where he/she has an epiphany that completes their transformation.
