Protagonist from WikiPedia:

A protagonist is the main character (the central or main figure) of a drama or story. The word "protagonist" derives from the Greek ????????????? (protagonistes), "one who plays the first part, chief actor." In the theatre of Ancient Greece, three actors played all of the main dramatic roles in a tragedy; the leading role was played by the protagonist, while the other roles were played by deuteragonist and the tritagonist.

The terms protagonist, main character and hero are variously (and rarely well) 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.
