According to your reading a traditional literary hero is most often

He is the main character in the story.  He has the qualities that other people admire such as strength, pure of heart, honesty, courage and loyalty.  He is generous to his followers and accomplishes his mission no matter how hard the odds are or how great the foe. More importantly, he is ready to risk his life for others or ready to sacrifice himself in the name of  truth and justice.
