Binary opposition, concept by Levi Strauss

 Levi Strauss' binary opposition theory identifies how within media texts, most commonly films, there is a binary opposite between two characters or forces. This is shown obviously within comics where there is a struggle for the good to win against evil.

 It is the contrast between two mutually exclusive terms, such as on and off, up and down, left and right.

Levi Strauss, proposed a theory of 'binary opposites' which entails that the majority of narratives in media forms such as books and film contain opposing main characters. These binary opposites help to thicken the plot and further the narrative; and introduce contrast.
