The Deuteragonist is the second important character in the story; the first is, of course, The Protagonist. This person can be either with, or against The Protagonist – thus sometimes pulling double duty as a main Antagonist, though they are rarely the primary antagonist in these scenarios. We can see how their actions drive the plot just as much as those of The Protagonist. If there’s another example of this trope in play following the previous one, then that character is the Tritagonist.
