The notion of protagonist lets name the main character of a work of fiction, whether literary, cinematographic or otherwise. The etymology of the word takes us to the Greek language, referring to the one who "The first part acts" or, what is it "Chief actor".
The protagonist, therefore, carries out the most important actions of the history . Without their participation, the plot would be meaningless. The protagonist's opponent is known as antagonist , and is that character that puts obstacles to the main character's goals. A work can have several protagonists and antagonists.
For example: "The protagonist of the series is Maxwell Smart, a rather clumsy secret agent who managed to succeed in his missions", "Despite the appearance of several superheroes, the undisputed protagonist of the film is Batman".
A clear example between what is protagonist and antagonist is the one seen in the highly successful literary saga that revolves around the figure of Harry Potter. The writer JK Rowling is the one who established as a main character the young magician who gives title to the work, it is a boy who studies magic at the Hogwarts School and who faces a multitude of adventures with his always inseparable friends Ron and Hermione .
The figure of antagonist is played by Lord Voldemort. This is Harry's staunch enemy, he becomes the leader of the dark side and tries by all means to destroy him in order to establish himself as the person with the most power. That will make both characters have to face endless battles and fights without quarter in order to make Good or Evil triumph, according to each one.
However, it is important to establish that both what is known as secondary characters exist in both literature and television series or movies. These have a minor participation in the story that is told but at certain times they also acquire a special relevance. That is, in those moments the reason for its appearance in the work in question is explained.
Returning to the literary and cinematographic saga of Harry Potter, we could establish that secondary figures such as Cedric Diggory, Teddy Lupine or Narcissa Malfoy are secondary characters.
To the actor Who plays the main character of a play is also known as the protagonist. In this way, the concept is applied to the real person and not to the fictional character: "Daniel Radcliffe is the protagonist of the film version of Harry Potter", "The protagonist of Steven Spielberg's last film was photographed on a Caribbean beach with a young unknown girl".
Protagonist is also the person or the thing that, in any event, plays the main part: “Andrés Iniesta was the exclusive protagonist of the game by scoring the decisive goal”, "The rain became the protagonist of the day by forcing the suspension of the shows".
