What Does “Side Character” Mean?

Simply put, a side character is any person in a story who is not the main character or protagonist. They play a secondary role. While the story doesn’t revolve around them, they are crucial for several reasons:

• Supporting the Protagonist: They help the main character on their journey, offer advice, or provide emotional support.
• Creating Conflict: They can be antagonists or create obstacles that the hero must overcome.
• Adding Depth: They help build the world of the story, making it feel more realistic and complete.

Sometimes, a side character is just there for a moment, while others have their own mini-arcs. The word you choose depends on their specific function and importance. Think of it like a movie: the lead actor is the star, but the film wouldn’t be the same without the talented cast of supporting actors.
