Want to Write More Believable Characters? Make ‘em Quirky

Strong characters are the foundation of any great novel.

There are many ways to make your characters seem more real and more human.

In our character development resources, we offer a detailed process for building characters from the inside out, starting with a nugget of a personality, then layering it with detail. We advise looking at your characters’ personality type and motivations, their voice and their backstory.

But even once you’ve built a solid, three dimensional character, with hopes, dreams and flaws, you might still feel there’s more that can be done to really bring them to life—and you could be right.

If you want to write truly believable, memorable characters you have to dive deeper into the little things; like giving your characters quirks.

Although it seems like quirks should be straightforward, they are often misunderstood. It’s wise to make sure that you’re using them correctly while avoiding the common mistakes.

A strong quirk can make your main characters immediately recognizable and forever remembered.

But poorly-used quirks can bore your readers or even turn them off.

What Are Character Quirks?

There’s a lot of confusion out there around quirks, so let’s start by getting clear on our definition.

Quirks are peculiar, surprising, unusual, defining, and/or memorable character idiosyncrasies. They stand out and make your characters unique. Quirks are often minor things your character has no conscious control over.

Unique is the real key here. A true quirk should cement the character in your readers’ minds so they associate that quirk with that character and that character only. defines quirks as distinguishing characteristics or qualities, especially of one’s personal nature.

But in novels, they are no random coincidences (not when done by the masters, anyway).

In fact, they are often physical features or behavioral manifestations of something central to the story: a broader personality trait, an unusual gift or talent, or perhaps an irrational fear or a rare strength or weakness.

Here are some examples:


  • Harry Potter’s lightning scar was an outward sign that he was the only person to ever survive the Avada Kedavra curse. As time went on, it became a window into Voldemort’s thoughts as well, a key part of the story line.
  • Darth Vader’s helmet and signature breathing is another, as it’s a constant reminder to himself and others of his battle with Obi-Wan Kenobi and his subsequent transformation into half-machine in order to survive.
  • Anne of Green Gables’ insistence that she is “Anne with an ‘e,’” is also a quirk, one that helps her distinguish herself from the “formula Ann” orphan stories of the time.

What Quirks Are Not

When it comes to recognizing or choosing quirks for your characters, it’s equally important to know what isn’t a quirk.

Quirks are not skills, knowledge, or specialties attained by study.

As an example: Even though some might think otherwise, Katniss’s hunting skills are not a “quirk.” They are an essential part of who she is as a person, an expertise and a set of skills she has deliberately acquired and honed.

Also, while her skills are exceptional, they are in no way unique. There are hundreds, probably thousands, of people who can shoot a bow as well as Katniss.

A quirk should be something that’s completely or almost completely unique to that person, and it will often have a taste of oddness to it.

Why You Should Give Your Characters Quirky Personality Traits

There are many great reasons to consider giving the gift of a quirk to at least one of your main characters. A well-applied quirk:

  • Makes your characters seem more real.
  • Makes your readers care about them more.
  • Makes your characters more relatable—for better or worse, they’ll be more endearing, charming, attractive, repulsive, unlikable, or annoying.
  • Makes your characters more memorable.

At their best, quirks are handy literary devices that can act as windows that let readers see inside your characters’ lives, foreshadowing more of what your characters could be.

5 Best Practices for Giving Your Characters Quirky Personality Traits

Here are a few tips for the best ways to incorporate character quirks:

  1. Draw your inspiration from real life, TV, or movies. Get in the habit of watching people and making notes. Don’t copy quirks exactly from other characters but use the ideas to riff off and come up with your own.
  2. Sprinkle quirks sparingly throughout your story. There’s no need to go overboard by overusing, exaggerating or over-describing them. Your quirks also don’t have to be so “out there” that they’re unbelievable. Not every main character needs one. A single character could have more than one quirk, but no single character needs more than one. Most writers who use quirks don’t need to worry about not being quirky enough. The bigger danger is crossing over the line into the unbelievable.
  3. Make quirks significant to the story and not incidental. Harry’s scar and Darth Vader’s helmet become more important to their respective stories as time goes on and as more backstory is revealed.
  4. Beware of and avoid cliches or quirks that are overused. Instead, try to mix things up and be original (see below for examples.)
  5. Don’t let your characters be slaves to their quirks. Instead, let your characters break role occasionally; it will make them more believable. For example, near the end of your story, your hero might decide he can skip his habitual quadruple-checking of every lock on the house in order to catch the train that will allow him to propose to his love interest before she leaves town forever.

Avoid Turning Vague Cliches Into Weak Character Quirks

So what’s an overused or weak quirk? Aside from the fact that they’re too general, they’re overly simplistic, used too frequently, often based on stereotypes, and don’t allow readers to know your characters well enough so they ring true.

If you can think of more than a few instances of a particular quirk in popular stories, it’s probably overused (and it’s best to avoid it.)

Some of these may also be genre specific, for example:

  • In romance, violet eyes
  • In fantasy, the completely unique birthmark, often shaped like a real object or a symbolic image, which shows the princess/hero/protagonist is the Chosen One.

Other possibilities:

  • Adorable kids with a lisp
  • Manic pixie dream girls
  • Autistic characters who are idiot savants
  • Smart girls with mousy appearances, wearing glasses
  • Shy person who hides behind stacks of books
  • Mad scientists with messy hair and crazy facial expressions
  • Disorganized, absent-minded professors
  • Evil antagonists with long, dirty fingernails or greasy, unkempt hair
  • Grumpy, grouchy angry old men
  • Gorgeous but brooding, despondent men
  • Women who love chocolate
  • Air-headed blonde women
  • The dashing, physically perfect hero
  • The plain, unconfident Jane
  • The princess needing to be saved
  • The high school hunk
  • Sarcastic teen girl who saves the world in the end

Bring Your Characters to Life with Quirks

Now that you’ve got a better idea of what character quirks are and how to use them, you can return to this list of quirks to flesh out your characters—as well as to recognize the quirks you might already be using without realizing it.

Next, challenge yourself to continually add to your own list of quirks. Sit down and brainstorm or just get into a habit of watching people and making notes of the inspiration that’s all around you.

Commit to paying attention and being more aware of the quirks you see in real life and in your favorite stories.

Like so much in writing, creating strong, memorable characters is an ongoing process. When you start being more deliberate and noticing quirks in the wild, you’ll become a better storyteller.

Then make sure you’ve completed the Ultimate Character Questionnaire for all your main characters.

Your characters, and your readers, will thank you.
