Full guide

A flat protagonist reads like an empty vessel designed solely to carry the author’s plot from scene to scene. While spectacular events might occur around them, the character themselves lacks an independent psychological interior, a distinct voice, or a compelling set of personal contradictions. This problem frequently surfaces when a writer spends all their creative energy engineering intricate plot twists or expansive world-building, leaving the main character as a passive observer who simply executes the actions required by the outline. If a protagonist has no clear internal wants, hidden fears, or fatal flaws, the reader will find it impossible to invest in their journey.
