A literary hero is someone like Odysseus in Homer's "The Odyssey" or the Greek god, Achilles. He or she is the main character in a work of literature, and usually has unique skills, admirable qualities, and some kind of remarkable talent. The heroes in ancient legends or literary epics were stronger than ordinary men, as well as more courageous.
Literary heroes may be proud, like Roland in the heroic poem, "The Song of Roland." In spite of his ultimately fatal flaw, readers still value him and see him as a hero because of his glory and bravery. The flaws of literary heroes make them relatable to ordinary people, and even more appealing to readers.
