The protagonist is the main character of the story. Everything evolves around him/her. Usually, in a story, the protagonist wants to reach a goal, but many obstacles are in his path to reach this goal. These obstacles can be natural (a storm, a tornado) or human. The human obstacles doesn't want that the protagonist reach his/her goal. The human obstacles are called "Antagonist". Other characters in a story are called minor characters.
