Because the Contagonist and Antagonist both have a negative effect on the Protagonist, they can easily be confused with one another. They are, however, two completely different archetypes because they have two completely different functions in the Story Mind. Whereas the Antagonist works to stop the Protagonist, the Contagonist acts to deflect the Protagonist. The Antagonist wants to prevent the Protagonist from making further progress, the Contagonist wants to delay or divert the Protagonist for a time.
As with the Sidekick, the Contagonist can be allied with either the Antagonist or the Protagonist. Often, Contagonists are cast as the Antagonist’s henchman or second-in-command. However, Contagonists are sometimes attached to the Protagonist where they function as a thorn in the side and bad influence. As a pair, Guardian and Contagonist function in the Story Mind as Conscience and Temptation, providing both a light to illuminate the proper path and the enticement to step off it.
