When choreographing a fight scene, a choreographer needs to know the strengths and limitations of each main character, along with his traits that are specific to each story.
The hero is usually the lead character and is the most active character in the story because his will and desire to overcome the odds propels the action. Typically, the hero is associated with self-sacrifice—he usually sacrifices his own needs on behalf of others. Sometimes the hero is reluctant to sacrifice himself because of ego, peer pressure, ignorance, fear, or insecurity. There can also be more than one hero in the story, such as the hero characters in The Avengers, The Three Musketeers, Fantastic Four, X-Men, The Seven Samurai
