Protagonist vs Antagonist, From the Greek Words Up

In protagonist vs antagonist, the protagonist is the main character, whose goal drives the story, and the antagonist is the character or force that stands in the way of that goal. Neither word says anything about good or evil. A hero can be the antagonist of a story told from the criminal's side, and an antagonist can be a loving mother, a storm or the protagonist's own fear.

The two words come from Greek drama, and both grew from one root, agōn, a contest. What follows sets out each word in its original sense, the related roles (the deuteragonist, the antihero, the villain), and a quick test for finding the protagonist in your own book. Every quote was checked in the original text.

What Is the Difference Between a Protagonist and an Antagonist?

The protagonist wants something. The antagonist is whatever makes it hard to get.

Merriam-Webster puts the moral point plainly: "Pro- and ant- usually mark the good and bad characters, but not always; there may occasionally be an evil protagonist and a good antagonist." The test is structural. Ask whose goal the story follows, and what stands against it.

What Does Protagonist Mean?

A protagonist is the principal character of a story. Merriam-Webster's first sense is "the principal character in a literary work (such as a drama or story)", and it dates the word in English to 1671.

The Greek prōtagōnistēs was a theatre word. Liddell and Scott's Greek-English Lexicon defines it as "one who plays the first part, chief actor". It is built from prōt-, "first", and agōnistēs, which Merriam-Webster glosses as "competitor at games, actor". The prefix is prōt-, not the Latin pro, "for". A protagonist is not the character the story is for. It is the one who comes first.

Aristotle's account of how tragedy grew uses the word. In Poetics IV, in S. H. Butcher's translation: "Aeschylus first introduced a second actor; he diminished the importance of the Chorus, and assigned the leading part to the dialogue. Sophocles raised the number of actors to three, and added scene-painting." The phrase "assigned the leading part to the dialogue" translates a verb form of the same word, prōtagōnistein. So in the best-known ancient use of the word in criticism, the first part does not go to a character at all. Aristotle gave it to the spoken scenes, over the chorus.

What Does Antagonist Mean?

An antagonist is the character or force that opposes the protagonist. Merriam-Webster's general sense is "one that contends with or opposes another", and it dates that sense in English to 1555, a century before "protagonist".

Unlike prōtagōnistēs, the Greek antagōnistēs was never a part on the stage. Liddell and Scott give "opponent, competitor, rival", from Xenophon, Euripides and Plato, with no theatrical sense at all. The Greeks numbered their actors first, second and third. They did not cast an antagonist.

Lajos Egri, in The Art of Dramatic Writing (1946), sets out the modern pairing in his section on the "pivotal character". "The pivotal character is the protagonist," he writes, and anyone who opposes that character is the antagonist. His reason for starting with the protagonist: "Without a pivotal character there is no play. The pivotal character is the one who creates conflict and makes the play move forward."

Robert McKee, in Story (1997), widens the opposing side beyond a single person. By "forces of antagonism", he writes, "we mean the sum total of all forces that oppose the character's will and desire." That sum can include nature, a society and the protagonist's own doubts, which are the classic types of conflict in literature.

Is the Antagonist Always the Villain?

No. A villain is one kind of antagonist: the kind who means harm. Every villain is an antagonist; most antagonists are not villains.

An antagonist only needs a goal that blocks the protagonist's. A rival who wants the same job, a father who wants his son to stay on the farm, a detective chasing a sympathetic thief: each stands in the way, and none is evil. These antagonists often make a story more painful, because the reader understands both sides.

When the antagonist is a villain, the craft is different: motive, strength and escalation. That is covered in writing a villain who carries a novel.

Can the Protagonist Be the Bad Guy?

Yes. The protagonist is the character the story follows, not the one it approves of. A story told from a thief's side makes the thief the protagonist and the detective the antagonist, however honest the detective is.

A protagonist who lacks the usual heroic virtues is called an antihero. Merriam-Webster defines the word as "a protagonist or notable figure who is conspicuously lacking in heroic qualities". The best-known statement of the idea is at the end of Dostoevsky's Notes from Underground (1864), in Constance Garnett's translation: "a novel needs a hero, and all the traits for an anti-hero are expressly gathered together here".

Dostoevsky is often said to have coined the word. He did not, in English at least: Merriam-Webster's first known use of "antihero" is 1714, a century and a half before his novel, and Garnett's English came later still.

What Is a Deuteragonist?

A deuteragonist is the second most important character, after the protagonist. In Greek theatre the word named the actor who played the second parts. Liddell and Scott define deuteragōnistēs as an "actor who takes second-class parts", and the tritagōnistēs as the "player who took the third part". Merriam-Webster gives the modern sense as "a person who serves as a foil to another". A foil character is a separate role again: someone whose contrast shows the protagonist's traits, whatever side they are on.

The numbers ranked status, not just order. Demosthenes, attacking his rival Aeschines, a former actor, in On the Crown (330 BC), calls him a tritagōnistēs. C. A. and J. H. Vince translate it as "you third-rate tragedian".

The deuteragonist is often confused with the antagonist, and they are separate roles. A deuteragonist can be the protagonist's best friend, partner or love interest. The Greek second actor played whatever parts came second, on any side.

Can a Story Have More Than One Protagonist?

Yes, in two ways, and McKee names both in Story. A Plural-Protagonist is a group that wants one thing and acts as one: "If one has a setback, all suffer." A Multiprotagonist story is different. Its characters "pursue separate and individual desires", each with their own plot, and McKee traces the form in the theatre back to A Midsummer Night's Dream.

Most novels still have one protagonist, and the reader should know early on who it is.

How Do You Tell Who the Protagonist Is?

Ask three questions. The character who answers to all three is the protagonist.

1. Whose goal starts the plot? The story is the pursuit of one character's want.
2. Who makes the choices? McKee: "A PROTAGONIST is a willful character. Other characters may be dogged, even inflexible, but the protagonist in particular is a willful being."
3. Who changes, or refuses to? The climax tests the protagonist, whatever kind of character arc they follow.

The protagonist is not always the narrator. Dr Watson tells most of the Sherlock Holmes stories, but Holmes drives them. The narrator is a question of point of view; the protagonist is a question of plot.

The antagonist follows from the protagonist's goal. Write that goal in one sentence, then ask what most stands in its way.

A Worked Example

Ada Penrose, seventeen, wants to sail the island race alone. Her mother, Joan, is the harbour master, and her signature is on every entry form. Joan's husband drowned on that course.

• Protagonist: Ada. Her goal starts the plot, she makes the choices, and the race is her test.
• Antagonist: Joan. Her goal, to keep Ada off the water, blocks Ada's. She is not a villain. She is afraid.

The scenes take turns:

1. The entry form. Ada fills it in. Joan refuses to sign.
2. The old boat. Ada repairs her father's boat at night.
3. The sale. Joan puts the boat up for sale.
4. The trial run. Ada sails the course in fog, and gets back.
5. The signature. Joan watches her come in, and signs.

The antagonist acts as often as the protagonist. That is what keeps the opposition alive. Because Joan is not a villain, the ending can be a change of heart rather than a defeat.

How Do You Set Up a Protagonist and Antagonist in Deckle?

Deckle is a novel-writing app. Its Codex keeps an entry for each character, with a Role, and its Outliner is a board of cards, one for every document in the book, each with a synopsis.

1. Open the Codex, click the + beside the Characters section, then Character, to start an entry from the built-in Character template. Name your protagonist.
2. Set the entry's Role to Protagonist, and write their goal in Motivation & Goals.
3. Make a second entry for the antagonist. Set its Role to Antagonist, and write a goal in Motivation & Goals that blocks the first. Each role has its own colour in the Codex, so the two read apart at a glance.
4. Open the Outliner on the Draft and add a card for each scene with Add › Scene. In each synopsis, write who acts and what they do.
5. Make two labels, "Protagonist" and "Antagonist" (the pencil beside Status in the Inspector's Properties opens Edit labels & statuses), and set one on each scene, for the character who drives it.
6. Switch the Outliner to its list and read the label column. A long run of "Protagonist" with no "Antagonist" is a stretch where the opposition has gone quiet.

The Codex entries are also where you keep each character consistent across a long draft. For the move and counter-move rhythm inside each scene, scene and sequel is the classic pattern.

Common Mistakes

• Treating protagonist as "good guy". The protagonist is the character the story follows. Morals are a separate question.
• Treating antagonist as "villain". Most antagonists are not villains. They only need a goal that blocks the protagonist's.
• A passive protagonist. If other characters make all the choices, one of them is the real protagonist.
• An antagonist who never acts. Opposition that only waits for the protagonist is scenery. Give the antagonist moves of their own.
• Calling the deuteragonist the antagonist. The deuteragonist is the second most important character, on either side.
• Reading "pro" as "for". The prefix is the Greek prōt-, "first".
