Question

Which two types of characters are usually least important to the story? antagonist and protagonist antagonist and flat character protagonist and round character round and flat character

Answer 1

antagonist and flat character

Answer 2

The Protagonist and Antagonist are the hero and villain, so they're EXTREMELY important. Though if your choices are

A) Antagonist and Protagonist

B) Antagonist and Flat Character

C) Protagonist and Round Character

then I would choose answer B. because a flat character would have no depth of backstory or dialogue and the Antagonist (Villain) is much less important than the Protagonist (Hero)
