A foil is a character whose traits contrast with the protagonist in ways that highlight the main character’s qualities. By showing someone who is similar in some ways but opposite in key aspects—such as cautious versus reckless, or pessimistic versus hopeful—the story makes the protagonist’s choices and growth more noticeable. The foil isn’t necessarily an enemy; they simply serve to illuminate the protagonist through contrast.

The other roles don’t fit as precisely. The protagonist is the central character, not someone who emphasizes contrasts. The antagonist opposes the protagonist’s goals, creating conflict rather than highlighting personality through contrast. The hero is typically a noble main character, not defined by contrasting with the protagonist.
