Headcanon Examples: 20 Lines, Each Annotated

Every headcanon example below carries the cell it came from — category first, tone second. One category with one tone holds exactly six lines, so you can find any of them yourself in a roll or two on the generator page. The name slot is filled with Ren here, because in the bank that slot is a variable and it appears exactly once in all 180 lines. That is why the same sentence can be pointed at any character you like.

Nothing on this page is quoted from another site, and no number on it is an estimate: the pool is fixed, so every count below comes from scanning the file that serves the tool. The annotations are the only judgement here, and they are mine.

One line from the bank and the five checks the other nineteen were read with; the counts on the right are a word-pattern scan of all 180 lines, so one line can be counted under two checks.

The five checks, one sentence each

An annotation is not a review. It is a question you ask of a line, and the answer tells you what the line is for. These five earn their place because each one answers the only question that matters to a scene: what do I actually put on the page?

• Cue — a repeated action tied to one moment. You can open the scene on the moment instead of describing the feeling.
• Prop — a physical object with a stated place or condition. You can put it on screen and let the reader do the work.
• Bill — what the habit costs, or what they will not ask for. Somebody pays, and that payment is the story.
• Number — a committed quantity, not a vague frequency. A number can be wrong, which means a reader can check it, which means a reader believes it.
• Turn — a second beat that reverses the first. That reversal is where surprise lives, and surprise is what makes a sentence worth keeping.

A line only needs one check to be usable. A line that passes none of them is a mood wearing a name, and moods sit in drafts forever without becoming scenes. The twenty lines below are four per check, taken from five categories and all six tones, each with one sentence about what it hands you.

1. Cue: a habit tied to a moment you can stage

• “Ren notices when someone has gone quiet for one conversation too long, and finds a reason to sit next to them.” Personality / Wholesome. The cue is one conversation of silence — not “when a friend is sad”, but a measurable event with a start and an end. You can write the beat where the silence begins, the beat where it has gone on one turn too long, and the beat where they move. The reader gets the noticing without ever being told about it.
• “Ren thanks the bus driver every single time, and means it every single time.” Quirks / Wholesome. The cue is the end of a bus ride: something that happens anyway, in any city, in any decade. This is the cheapest cue there is, and the one to hunt for when your scene already contains a small repeated event — a kettle, a lift, a door. Hang the habit on it and the habit costs you no setup at all.
• “Ren double-checks the lock three times and still gets up once more.” Quirks / Angsty. The cue is the second they get into bed, and it is doing the job an adjective would have done badly. Write “anxious” and you have handed the reader a label; write “gets up once more” and the reader is standing in the hallway with them. The number three appears here, but it is the getting up that carries the line.
• “Ren checks the time out of habit exactly at an hour that used to matter.” Quirks / Melancholy. The cue is an exact hour, and the line refuses to name it. That refusal is the part to inherit: you must decide the hour for yourself and then never explain why it matters. Set one clock in one scene, have them look at it, say nothing.

2. Prop: an object with a place or a condition

• “Ren keeps the key to a place that no longer exists.” Backstory / Melancholy. The prop is a key with no lock on the other end of it. A camera finds it in ten seconds: a drawer opening, a ring of keys, one of them wrong. The moment you show it the reader starts asking a question, and the story gets to dodge that question for as long as it wants.
• “Ren keeps a jar of spare buttons, batteries and small kindnesses in case anyone needs one.” Quirks / Wholesome. The prop list is built from two ordinary items and one that is not a physical object at all. On screen the shelf looks completely normal for one beat and then is not — that small collision is a prop doing a character’s job better than any line of description.
• “Ren keeps a note on their phone titled with a date and nothing else.” Secrets / Romantic. The prop is a note with no body, only a title. There is nothing to read on screen, which is exactly why it holds a scene: the character opens it, the reader cannot see it, and the gap between those two facts is the whole beat.
• “Ren keeps a photo face down on a shelf and has not turned it over in a long time.” Secrets / Melancholy. Two props in one line: the photo and its position. Position is the part you can stage with no dialogue whatsoever — a hand reaches past it, straightens it, or finally turns it over, and each of those three gestures is a different scene.

3. Bill: who pays, and what it costs

• “Ren is the first to offer help and the last to accept any.” Personality / Angsty. The bill is a one-way street. Help flows out and never comes back, and because the line states both halves you can stage the asymmetry in two moves: someone offers, and the refusal costs the offerer something. Nothing has to be explained out loud.
• “Ren was praised for being easy to look after, and has been trying to be harder to leave ever since.” Backstory / Angsty. The bill is that being low-maintenance was paid for with the right to be missed. The line converts a compliment into a debt and then states the repayment plan in the same sentence, which is exactly the shape a backstory needs if it is going to be usable in a scene rather than merely known.
• “Ren is the one everyone calls at two in the morning, and the one nobody thinks to call at noon.” Relationships / Angsty. The bill is a timetable: indispensable at night, invisible in daylight. Because both halves are times, you can stage the same person twice — once in each slot — and let the reader do the arithmetic between them without you pointing at it.
• “Ren will run their phone down to one percent rather than ask to borrow a charger.” Quirks / Angsty. The bill here is pride paid in small change. Nothing dramatic happens: the phone dies in the middle of something and the character acts as though that were fine. Cheap to write, easy to film, and it tells you more about them than a paragraph of their history would.

4. Number: a quantity that commits

• “Ren cannot leave a group chat unread, but still takes eleven minutes to type ok.” Personality / Funny. Eleven minutes turns a joke into a person. “Takes ages to reply” would be a quirk; a number with an exact unit is a measurement, and a measurement lets the reader picture the whole eleven minutes, which is where the comedy is.
• “Ren will drive four hours for a friend and complain about it the entire way there and back.” Relationships / Chaotic. Four hours is large enough to be unreasonable, and unreasonable is the joke. The number also sets the length of your scene: you have a road, a complaint, a return, and no need to invent a plot, because the distance is already the plot.
• “Ren holds doors three steps too early, every time.” Quirks / Romantic. Three steps is calibrated precisely enough to be too early rather than merely early, and the trailing “every time” converts a moment into a habit. Together they give the reader a behaviour they can predict and be charmed by, which is a far better use of fifty characters than a compliment.
• “Ren has been about to learn how to swim for eleven years and stands by the plan.” Secrets / Funny. Eleven years makes the plan into self-mythology rather than an intention. If you want the beat to land funny, put the line in a scene with water in it; if you want it to land sad, put it next to someone who swims without thinking about it.

5. Turn: a second beat that reverses the first

• “Ren falls slowly, then all at once, and everyone around them notices months before they do.” Personality / Romantic. Two reversals are stacked here. The first is the pace, which flips mid-sentence; the second is the point of view, which flips to the room. That second half also hands you a whole cast for free: everyone already knows, so you never have to introduce a single person to a scene about them.
• “Ren says it does not matter before anyone has asked, which is how you know that it does.” Personality / Angsty. The turn is a refusal that arrives before the question. Nobody asked, and the answer came anyway, and that timing is a scene on its own. The final clause then tells the reader how to read the first half, which saves you the paragraph of interiority you were about to write.
• “Ren always takes the same seat, and gives it up immediately if someone else wants it.” Quirks / Wholesome. The turn is generosity set against a fixed habit, and the habit is what makes the generosity legible. Without the first half the second half is ordinary politeness. Keep habits in your notes precisely so that a later reversal has something to push against.
• “Ren writes lists, loses the lists, and trusts the lists anyway.” Quirks / Chaotic. Three beats, and the third contradicts the first two. This is the shape to steal when you want a funny line with a floor underneath it: the joke lands, and then the sentence keeps standing, which is why it can survive being reused in a serious scene later.

What those twenty cost: the counts behind them

The lines above were not chosen from a pile of equal candidates. They were taken from a pool whose exact shape can be counted, and the shape explains why some of the checks are easy to find and others are rare. Every figure here comes from scanning this site’s own source file.

• 180 lines, 30 cells, six per cell. Five categories (Personality, Backstory, Relationships, Quirks, Secrets) across six tones (Wholesome, Funny, Romantic, Angsty, Chaotic, Melancholy), six lines in every cell. One category with one tone is a closed set of six, which is what makes the look-up steps further down this page work.
• 180 of 180 lines open with the name slot, and the slot appears exactly once in every one of them. No line contains a second capitalised proper noun mid-sentence, no line contains a year, and none contains an amount of money. Exactly one line in the whole bank contains a digit. The pool is deliberately world-free, so nothing in it can be wrong for your character.
• 0 of the 180 contain a quotation. There is no dialogue anywhere in the bank. That looks like a gap until you notice what it buys you: every line describes a person, and none of them puts words in that person’s mouth, so no line can fight with the voice you have already given your character.
• Length: 46 to 143 characters counting the name slot as a single character, median 80.5. In words, 9 to 26 with a median of 15. That is roughly one breath, which is the reason a line can be dropped into a scene that already exists without rewriting the scene.
• The scan, by check: 94 of the 180 lines show at least one of the five patterns in their wording — 49 with a prop, 26 with a bill, 21 with a number, 20 with a turn, 11 with a cue. Twenty-five lines show two or more. The check count in the diagram is a count of wording, not of meaning, so a line can appear under more than one heading.
• The bill is concentrated in one tone. Eleven of the thirty Angsty lines state a cost, against one of the thirty Funny lines. If you are hunting for a line where somebody pays for something, you already know which tone to click first.
• Props live in one column. Twenty of the thirty-six Quirks lines name a physical object, against two of the thirty-six Relationships lines. Props are a habit-category tool: they show what a person does when nobody is watching, which is exactly what the Quirks column is for.
• Committed numbers are a chaos tool. Eight of the thirty Chaotic lines carry a number, against none of the thirty Wholesome lines. Wholesome lines tend to describe a disposition; Chaotic lines tend to describe an incident, and incidents have quantities.
• The honest part: 86 of the 180 lines show none of the five patterns and are not the weakest lines in the bank. The mechanism is usually written in plain words, which is the argument for annotating by hand instead of filtering. A keyword search over this bank would hand you 94 lines and quietly hide the other 86.

Of the twenty lines I annotated above, six are Angsty, while Angsty is only thirty of the hundred and eighty lines in the bank. That is not a defect in the method, it is the method showing through: the bill is the check that most often decides whether a line is worth keeping, and the bill is paid in one tone. If you annotate your own lines and find the same skew, keep it. A set with a centre of gravity reads like a character. A set that is evenly spread across six tones reads like a spreadsheet. If you want the distribution story rather than the writing story, the repeat piece covers it, including why two characters can end up sharing lines.

Annotate your own lines in three passes

The twenty lines are a demonstration, not the product. The product is being able to look at a sentence you wrote and say what it gives you, which is a skill you can rehearse on a page of your own notes in about ten minutes.

• Pass one: underline every concrete noun. Not the feelings, the nouns. If there is nothing to underline, stop here — the line is a mood, and no amount of rewriting will make it stageable until you put an object next to it.
• Pass two: circle the cue. Which moment does the behaviour attach to? If the honest answer is “always”, narrow it until it fits inside one scene. “Always takes the same seat” becomes “takes the seat by the door, every morning”. The narrower version is the one you can shoot.
• Pass three: name the bill. Who pays for this habit, and in what currency — time, pride, sleep, the right to be missed? If nobody pays anything, you have written a description of a nice person. Nice people are not scenes.

Then rebuild with four slots, which is the fastest way to turn an annotation into prose:

• The cue: the moment ______ happens,
• The action: they ______ (one verb you could film),
• The prop: and the only thing on screen is ______,
• The bill: which costs them ______.

Fill all four and you have a beat rather than a bullet point. Leave one empty and it usually still works. Leave the bill empty and you are writing decoration, which is the most common way a good idea ends up as a note nobody rereads. And one test the bank passes 180 times out of 180: swap the name and the sentence still describes a person. Because no line names a second person, a year, a place or a price, there is nothing for it to be about except the character. Apply the same test to your draft. If changing the name breaks your line, the line was about an event that happened to them, not about them.

Where the twenty came from, and how to check them

Reproducing any line above takes one minute, no account, and no special knowledge:

• Open the generator and type a name. The name is one of the inputs to the shuffle, so it changes which lines come back.
• Turn off four of the five category chips, leaving only the category printed next to the example you want.
• Click the single tone chip printed next to it. The other five stay off.
• Set the count to 5 and roll.

That cell contains exactly six lines, and the batch you see immediately after setting the controls is always the same batch for that name, because touching a chip resets the shuffle and rolls straight away. So the first roll or two will show you five of the six lines in the cell, and one of them is the line quoted on this page. If you want the deeper version of that mechanism — which controls seed the shuffle and how to make a set repeat exactly — the step-by-step walkthrough takes it apart control by control.

Quick answers

• Do these headcanon examples come from a specific show or game? No, and that is structural rather than a choice of subject. Zero lines in the bank name a second person, a place with a capital letter, a year or a price, so the pool has no world attached to it. That is also what makes it safe to move a line into an alternate setting; if you are doing that deliberately, the consistency checklist is the companion piece.
• How many should I keep per character? The bank is arranged as five categories by six tones, which gives thirty cells to choose from. Six lines is one category at one tone; thirty lines is one full page of one category per tone. For a count with reasons attached, the matrix guide walks through one category, two to three, and all five; the one-page template is the printable version of that decision.
• How is this different from the other example pages on this site? The relationship piece starts with a relationship line and turns it into a scene, and the appearance piece covers the half of a character the bank deliberately does not touch. This page is about notation: the same twenty-line pool, read with five labels you can then use on your own sentences.
• What if two of my characters get the same line? They will, and the number is not small: two different names drawing from the same cells share about five lines out of thirty. The non-repeating piece measured it and gives the workaround, which is to write one anchoring sentence per line so the shared sentence carries a different debt for each character.

More of these notes, including how the bank is laid out and what it does with a name you type, are collected on the guides page.
