TL;DR
Agency is choice under constraint, never external power. Passive protagonists watch events unfold. Constrained protagonists make choices under impossible pressure, where every decision costs something real. Often the most active protagonist in a scene is the one with the least external power. This course teaches you to build that kind of hero, and to use AI to test whether your protagonist’s choices drive the plot, never to make the choices for them.
The scene that taught me the most about protagonist agency comes from Through the Looking Glass, a fictionalized memoir about a cam model in Bucharest. Zeya finds a ring in her nightstand that a member arranged to have placed there. The door won’t open. The computer won’t respond. A man holds a gun under his chin and tells her that if she doesn’t say she loves him, he’ll pull the trigger. She says it. He says he doesn’t believe her. He pulls the trigger.
Everything in that scene sits outside Zeya’s control except what she chooses to say and how she says it. Her agency is reduced to words, and the words aren’t enough. That’s a protagonist whose choices under maximum constraint define exactly who she is.
A passive protagonist sinks a book faster than any other flaw I can name, and the fix is harder to spot than it looks. Writers assume their hero needs more power or more options. Zeya has neither, and I can’t take my eyes off her.
Constraint is where agency lives
Readers can’t look away from Zeya because every word she says is a choice with irreversible consequences, and she knows it. External power and agency are different things entirely. Her external power in that room is zero. Her agency is total. This is the distinction the course is built around. Passive protagonists make no choices that cost anything. Active protagonists make choices under constraint where something real is always at stake. Rebuild your plot around those moments and the passivity disappears, whatever your protagonist’s circumstances.
I think this is the most misunderstood idea in fiction craft. Writers hear active protagonist and picture someone kicking down doors. The most active person in a scene can be the one who can’t leave the room, deciding what to say.

The moment things stop happening to your hero
Jake Martinez in Jake and the Bullies starts with even less power than Zeya.
He gets hit by a dodgeball, the video goes viral, and the internet turns on him. He’s twelve. Events carry him until the moment he has to choose whether to fight the Hate Engine the way it fights him, or find a different weapon.
That choice, made under maximum pressure, is the whole book. Take it away and you have a kid things happen to. Give it to him and you have a protagonist. The difference between those two versions of Jake is the difference between a story and a sequence of events. A kid things happen to is a book I’d put down after a chapter. A kid who has to choose how to fight back, knowing the wrong choice could turn him into what he’s fighting, is a book I’d read to the end.
Want against need drives the story
Want is the conscious goal your protagonist pursues. Need is what they require for fulfillment, often something they don’t recognize. Zeya wants money, stability, and to finish her veterinary degree. She needs dignity and self-determination, and the cam studio gives her the want while threatening the need every day. Jake wants the bullying to stop. He needs to understand that the capacity for cruelty he’s fighting exists in himself. The arc is always the distance between the two, and the full handbook covers seven hero types and how each one travels it.
Want against need is the part of character work I find most satisfying, because the gap never closes neatly. Zeya getting the money while the studio chips at her dignity every day was a hard thing to put on the page, and it’s a big part of why that book matters to me.
Arcs that hold across a series, and arcs that stay flat
Jessica Lang in the Peacekeeper series crosses 200,000 years, and the garden of skulls in her dreams, every person she’s ordered killed, is structural. Each book tests a different dimension of what that wound costs her. Series protagonists need the destination planned before book one, then an arc parceled into installments that each feel complete.
Flat arc protagonists work differently: they already know the truth, and the story tests that knowledge under maximum pressure to prove it holds. A protagonist who ends the book unchanged because their values were never seriously challenged is something else entirely. That’s a character who was never in the story.
A protagonist who ends the book unchanged because nothing ever pushed hard on their values is a wasted book, in my view. I’d take a flat arc tested to the breaking point over a changing arc that was never under any pressure.
How can AI help with writing a protagonist?
No tool decides what your protagonist would do; that judgment is the job.
AI earns its keep in the testing. The course’s 40+ prompts have it trace your protagonist’s decisions across a manuscript and flag scenes where events happen to them without a choice being made, check whether a choice under pressure matches the psychology you established, and map the distance between want and need at each act break. It measures the agency. You supply it.
Give your hero a choice that costs something in every major scene and readers will follow them anywhere. I’d take a powerless protagonist making hard choices over an all-powerful one who never has to decide anything, and I think most readers would too.
