Character Titles

Protagonists. Antagonists. I believe that these two words are the most commonly used when it comes to describe a character role in stories or movies.

Ever heard of deuteragonists? Tritagonists?

A Deuteragonist is the second most important character (aka sidekick). And as for the Tritagonist, it's referring to the third most important character (example: Hermione Granger).

Well most stories are often straight forward. There is only one Protagonist. Rarely the story takes so much a twist and turn that it has more than 1 Protagonist.

Oh but there is one...
