The word “hero” or “heroine” is occasionally used just to characterize the protagonist of a story, or the love interest, a use which can conflict with the superhuman expectations of heroism. Vanity Fair was given the subtitle A Novel with no Hero by William Makepeace Thackeray. The larger than life hero is a prevalent characteristic of fantasy (especially sword and sorcery and epic fantasy) than more realist works.
In modern films, the hero is usually just a normal man in extraordinary conditions, who, regardless of the odds being stacked against her or him, generally endures in the end. In a few films (particularly action movies), a hero may demonstrate features including superhuman strength and endurance to the stage of the hero being almost invincible. Frequently a hero in these types of scenarios has a foil, the villain, usually a magnetic evildoer who embodies the battle the hero is up against, or symbolizes, directs.
Postmodern fictional works have fomented the increased popularity of the antihero, who doesn’t follow common concepts of heroism. Cases of contemporary heroes are Superman, and Harry Potter, Katniss Everdeen, Percy Jackson, Bilbo Baggins, Luke Skywalker.
