What are unnamed protagonists?

Answer 1

Sometimes (not always) unnamed protagonists are referred to as 'Reader Portals'. This means that the reader is expected to put himself in the position of the protagonist. The character is left unnamed, undefined, and undescribed on purpose to help facilitate this identification.

Answer 2

Unnamed protagonists are characters in a story who are not given a specific name. This literary device allows readers to project themselves onto the character, creating a more immersive experience by fostering a sense of identification with the protagonist. Examples include "The Man" and "The Boy" in Cormac McCarthy's "The Road."
