What type of character is likely to serve as the hero or main figure in a story?

The protagonist is typically the character who serves as the central figure in a story, around whom the plot revolves. This character often faces challenges and conflicts that the narrative explores. The protagonist is critical in driving the story forward, engaging readers with their journey and growth. While a protagonist can be a round character, dynamic character, or even a static character in different contexts, the key distinction is that the protagonist is the main character, regardless of their development throughout the story.

Other types of characters can support the main character's journey or contrast with them but do not serve as the focal point of the story as the protagonist does.
