Anyone who has ever found themselves having to tell a story, and making decisions about how to do it, knows that getting the villain, the threat or simply the counterpart, is much more important than hitting a great protagonist.
The villain refers to a type of plot radically divided into two, in which there are the good and the evil, to superhero movies and Disney cartoons.
But in a greater sense, villains are all those who oppose the protagonists, who put a stick in their wheels and who have enough charisma to attract, frighten and bewitch.
