A protagonist (from the Greek πρωταγωνιστής protagonistes, “one who plays the first part, chief actor”) is the main character (the central or primary personal figure) of a literary, theatrical, cinematic, or musical narrative, around whom the events of the narrative’s plot revolve and with whom the audience is intended to most identify.
The terms protagonist, main character and hero are variously defined and, depending on the source, may denote different concepts. In fiction, the story of the protagonist may be told from the perspective of a different character (who may also, but not necessarily, be the narrator). An example would be a narrator who relates the fate of several protagonists, perhaps as prominent figures recalled in a biographical perspective. Often, the protagonist in a narrative is also the same person as the focal character, though the two terms are distinct. Excitement and intrigue alone is what the audience feels toward a focal character, while a sense of empathy about the character’s objectives and emotions is what the audience feels toward the protagonist. Although the protagonist is often referred to as the “good guy”, it is entirely possible for a story’s protagonist to be the clear villain, or antihero, of the piece.
When the work contain subplots, these may have different protagonists from the main plot.
Lol was his everything. His absolute everything. And sure he’s got the gang and all that to bear in mind but - his relationship with Lol, you know they were that sort of perfect couple, I suppose, aren’t they? Woody would be devastated splitting up with Lol, definitely. She’s his absolute everything. - Joe Gilgun
