How to develop characters: want, need, wound and arc

Character development is the change a character goes through, or refuses, over a story, and the groundwork that makes it believable. To build it, decide three things before you draft: what they want (a goal they could name), what they need (a truth they are avoiding) and the wound that taught them to avoid it. Then build a plot that forces a choice between the want and the need, and stage that choice in a scene. What they choose sets the arc: positive if they accept the truth, flat if they already hold it and change the people around them, negative if they refuse it.

Characterization vs. development

Characterization is the surface: name, job, voice, habits, the way someone answers the phone. Development is the structure underneath: what the person is after, what they are wrong about, and what the story does to them. A character sheet earns its keep when it answers one question: what will this person do when the story leans on them?

E. M. Forster drew the classic line in Aspects of the Novel (1927) between flat characters, built around a single idea, and round ones. His test for roundness still holds: a round character is "capable of surprising in a convincing way." Round isn't the same as changing: a complex character can hold steady from first page to last.

Want, need and the wound

Screenwriting manuals and novelists' craft books describe the same three parts, plus the belief that ties them together.

• The want is the external goal: the job, the house, the person, the revenge. It drives the plot, and a reader can tell whether the character gets it.
• The need is the internal correction the character doesn't know they need, best written as a truth: "Love isn't earned by being useful."
• The wound is the past event that made the need hard to see. John Truby calls it the ghost in The Anatomy of Story (2007): an old event that still has a grip on the hero and usually sits behind the weakness the story will test.
• The lie is the belief the wound left behind. It made sense once, it still feels like protection, and it now does damage. K. M. Weiland builds Creating Character Arcs (2016) around it: the want serves the lie, the need serves the truth.

Four novels you can read free online show how they line up.

The want and the need can't both be fully satisfied. Jane can have Rochester on his terms or keep her self-respect, and the novel turns on her choice. Rochester begs her to stay, and her own feelings plead his case. She answers them, "I care for myself," and slips out of Thornfield before the house wakes.

Choose the arc: positive, flat or negative

The arc is what happens to the lie. Weiland sorts arcs into three families, and they work well as a menu of endings.

Positive change arc

The character starts inside the lie, chases the want, finds it isn't enough, and ends by acting on the truth. Elizabeth rereads Darcy's letter and sees her own prejudice: "Till this moment I never knew myself."

Flat arc

The character already holds the truth, and the story tests whether they can keep it, and change others, in a world that believes the lie. In Pollyanna (1913), the girl's "glad game" wins over her stern Aunt Polly and the town's hardest cases. When an accident leaves her unable to walk, she can't find anything to be glad about, and one townsperson after another calls at the house with word of what her game changed in them. Flat doesn't mean dull: a flat-arc protagonist can doubt and waver for long stretches and still come back to the truth.

Negative change arc

The character ends worse off, in one of three ways Weiland describes. In a disillusionment arc they reach the truth and find it bleak: Nick Carraway sees through the glamour of the East in The Great Gatsby (1925) and goes home emptied. In a fall they cling to the lie as the cost mounts: Victor Frankenstein stays silent while Justine is tried for a murder his creature committed. In a corruption arc they start near the truth and trade it away, as Macbeth goes from loyal general to tyrant.

One character, three arcs

To see how much the arc decides, take one original setup. Nora Quist, 31, is a court reporter. At 14 she spoke to the judge at her parents' custody hearing. The judge quoted her in his ruling, and her father moved out of state. The lesson she took: her words break things, and safe people stay quiet. Now she wants the senior post at the federal courthouse, and the clerk who can get it for her asks a favor. Would she smooth one remark of the judge's out of a trial transcript before the appeal?

Decide the ending before you draft the middle. Every scene in between either builds toward that final choice or is in the wrong book.

Show the change on the page

In Story (1997), Robert McKee argues that true character comes out in choices made under pressure, and the more pressure, the more a choice reveals. A realization in narration is a promise. A decision in a scene is proof. This is show, don't tell applied to a whole arc.

• Bookend scenes. Open with a situation that shows the lie at work. Close with the same situation and a different response.
• A cost on every turning choice. If acting on the truth is free, it proves nothing. Nora's honesty should cost her the job she wanted.
• One relapse. Let the character slide back once, usually after the midpoint, when the old belief looks safe again.
• Witnesses. Let another character notice the difference and react, so the narrator doesn't have to point.

Nothing in the second scene says she has changed. The reader knows because they remember the potatoes.

Keep an arc ledger

A ledger is one row per turning point: where it falls, what the character chooses, and which belief the choice serves. It shows at a glance whether the change builds or stalls.

If every row says "Truth" after the inciting incident, the change is too easy. If none does until the climax, it will feel sudden.

Develop secondary characters

Supporting characters get less page time, not less logic. Give each one a want in every scene they appear in, even a small one: the bailiff wants to go home on time, and that is why he rushes the witness. Then decide how each one relates to the protagonist's lie. Most casts fill some of these roles:

• The mirror shares the wound or the temptation and made the other choice. Dolores, the senior reporter who trained Nora, smoothed a transcript once and has been careful ever since. She is Nora's negative arc in a cardigan.
• The foil has opposite traits that make the protagonist's visible. Sam has never kept a thought to himself in his life.
• The pressure wants something that only works if the protagonist stays inside the lie. Grant, the clerk, isn't a villain. He owes the judge his career, and to him the edit is loyalty.
• The witness to the truth lives by the need without preaching it. Here that is the court interpreter, who corrects her own mistakes on the record without fuss.

Forster defended flat characters too: they are easy to recognize and easy to remember. Minor characters can stay flat if the flatness is a choice. A quick test for the rest: if this person walked out of the scene, would they have somewhere to go? For antagonists, see how to write a villain readers believe in.

How to develop a character, step by step

1. Start from what the story will test

   Name the question the plot asks, then build the person it hurts most. A story about loyalty needs someone whose loyalty is the problem.

2. Write the want as a goal with a deadline

   "Wants respect" can't be staged. "Wants the senior post before the October hiring round" can, and it gives you a clock.

3. Write the lie and the need in one sentence each

   Lie: "My words break things." Need: "Plain truth can repair what silence broke." If you can't write the need, you don't yet know what the book is about.

4. Find the wound in a single scene

   Draft it as a scene, even if it never appears in the book: one afternoon, with a date and a place. Then keep it out of chapter one. A wound explained on page three is an info dump and leaves the reader nothing to discover.

5. Decide the final choice, then the arc

   Decide what the character does at the climax. The arc and the tone of the ending follow from that choice.

6. Plan the proof scenes

   Fill in a ledger for the opening, inciting incident, midpoint, dark moment, climax and closing. Each needs something the character does. These beats slot straight into a plan when you outline the novel.

7. Draft, then audit the choices

   After a full draft, reread only the protagonist's decisions. Where one feels unearned, add a scene before it rather than a paragraph of explanation.

The character profile template has fields for want and need, backstory and wound, and the arc from start to end, so the answers to these steps end up in one place. For the patterns readers already recognize, such as the Sage or the Caregiver, see character archetypes.

Common character development mistakes

• The questionnaire trap. A hundred answers about favorite foods and childhood pets, and not one that produces a scene. Fill in only what creates pressure.
• A want with no need. The character becomes an action figure: busy, competent and unchanged. The reverse, a need with no want, is a mood with no plot.
• Change by announcement. An epiphany in narration, followed by the same behavior as before.
• Overnight transformation. One conversation erases a belief the character has held for twenty years. Give the lie at least two chances to win.

Keep your cast beside the manuscript

Character work pays off only if it is at hand while you draft. Keep one document per main character, with the want, need, wound, lie, arc and ledger, in the same folder as the chapters. In Strokes, a book can be a project folder of documents on your own machine. Add a profile and a chapter to a chat with the AI Assistant and ask where the character acts against the lie, or whether a choice feels earned. You decide what changes. Version history keeps earlier drafts, so when you rework an arc you can compare the old chapter with the new one.
