What new insights or narratives emerge when a story traditionally centered on a heroic figure is retold from the perspective of a previously secondary or marginalized character?

This thread examines narratives that shift the protagonist role from a well-known, central figure to a character who was historically minor, overlooked, or existed in the periphery of the original story. It originates with works that give voice to the 'other' in established narratives and evolves to explore themes of agency, hidden histories, and the subjective nature of heroism.
