Creating Unforgettable Side Characters: How to Write Supporting Characters that Shine

Introduction

While your protagonist takes center stage, well-developed side characters can add depth, humor, and emotional weight to your story. In this post, I’ll show you how to craft unforgettable supporting characters who enhance your plot and become fan favorites.

Step 1: Give Them a Purpose

Every side character should have a clear purpose in your story, whether it’s to challenge the protagonist, provide comic relief, or reveal important information. Avoid “filler” characters who don’t contribute to the plot.

Example: In one of my novels, a side character acts as both a mentor and a foil to the protagonist, offering wisdom while also highlighting the protagonist’s flaws.

Step 2: Develop Their Backstory

Just like your protagonist, side characters should have a backstory that informs their motivations and actions. This makes them feel more real and complex, even if you don’t reveal every detail.

Example: In Harry Potter, minor characters like Neville Longbottom have rich backstories that make their character arcs more rewarding.

Step 3: Give Them Distinct Personalities

Ensure each side character has their own distinct voice, quirks, and personality traits. This will make them stand out and feel like fully realized individuals, not just background figures.

Example: In my book, a side character’s dry wit and habit of quoting old literature make them memorable, even though they aren’t the focus of the story.

Conclusion

Supporting characters play a crucial role in bringing your story to life. By giving them a clear purpose, developing their backstories, and giving them unique personalities, you’ll create side characters who are just as unforgettable as your protagonist, enriching your readers’ experience.
