Tips for Using Dark Characters
Here are a few tips and tricks for adding an evil character to your story.
Balance Darkness with Depth
Don’t stop at “evil.” Give your dark characters layers. Maybe they’re cruel because they’ve been hurt, or their actions are rooted in a twisted sense of justice. Complexity makes them memorable.Motivations Matter
Why do they do what they do? Dive into their past and goals. A villain with a clear reason for their actions—even if it’s warped—feels more real and compelling.Tie The Character to the Theme
Their darkness should connect to your story’s message. If your theme is about power, let their choices explore what power does to people. If it’s about redemption, maybe their darkness shows what happens without it.Use Them Sparingly
A cast full of dark characters can feel heavy and overwhelming. Pick a few that really matter to the plot and let their presence hit harder. Sometimes, less is more.
Writing Exercise
Ready to create your own evil character? These simple steps will help you create someone who adds tension and a little chaos to your story.
1. Pick a Category
Start by picking a type of dark character from this article—like Tragic Antiheroes, Lurking Threats, or Reluctant Monsters. Think about how this character fits into your world and shakes things up for your protagonist.

Make your character unforgettable by giving them a surprising trait or backstory. For example:
A reluctant monster trying to save people but causing even more destruction.
A twisted ally who seems loyal but has a hidden agenda.
A tormented visionary whose obsession drives both brilliance and chaos.
This twist makes your character stand out and keeps readers guessing.

The more you play with their role, the more vivid they’ll become.
