Tritagonist vs. Protagonist — What's the Difference?

In literature, the tritagonist or tertiary main character (from Ancient Greek: τριταγωνιστής, tritagōnistḗs, third actor) is the third most important character of a narrative, after the protagonist and deuteragonist. In ancient Greek drama, the tritagonist was the third member of the acting troupe.

A protagonist (from Ancient Greek πρωταγωνιστής, prōtagōnistḗs 'one who plays the first part, chief actor') is the main character of a story. The protagonist makes key decisions that affect the plot, primarily influencing the story and propelling it forward and is often the character who faces the most significant obstacles.
