One of the first rules for your Protagonist is that they should want something, and ideally they should be wanting something they are actively in pursuit of. A passive Protagonist has things happening to them and around them, and they’re reacting to those things, rather than pursuing something themselves.
The lie your Protagonist believes takes your character at the start of your story where they will believe something about the world, and follows them through the course of the story as they learn the truth.
Your characters are one of the most important things about your story, they’re how your audience connects to the story you’re telling, how your plot moves along, and, usually, the point of the story in the first place. To write good characters that your audience will be interested in and want to follow, either by reading or watching, you have to be good at characterisation. How you bring them alive and make them interesting.
I’ve written before about the difference between the Protaognist and the Antagonist in your story and how you use them, but in some stories you’ll want to use multiple antagonists. I’ll give you some examples of how multiple antagonists can be used in one story, different kinds, and the effect it has, using one of my favourite films in the whole world as an example: Jurassic Park.
If you’re writing an ensemble cast, rather than just a single protagonist and antagonist, you may need to be able to write with multiple Protagonists, and understand what that means and how to do it well. However, an ensemble cast doesn’t necessarily mean you have multiple protagonists, you may have a large cast revolving around a single Protagonist. They’re only a Protagonist if you’re directly following their story.
The Death Of A Mentor is a technique used in story to motivate the Protagonist, by killing the person who has taught them to do what it is they do.
Most of the time when you go into reading a book or watching a film, there will be a person who’s telling you the story, it might be the lead character who’s POV you’re in, or an actual narrator. That’s usually a person who you trust is giving you an accurate account of the events occurring in your story. However, there is such a thing as an “unreliable narrator,” and I’ll be explaining how and why you might use an “unreliable narrator” by referencing the book The Girl On The Train by Paula Hawkins.
If you’re a writer you’ll have heard the terms “protagonist” and “antagonist,” and you might have a baseline familiarity with what they are, but you might not have a complete understanding of the meaning. So to make it clear what they are, I’m going to explain exactly what these words mean, and reference the film Terminator 2 as an example of a Protagonist and an Antagonist.
