A foil is a character in a story who contrasts with another character, typically the protagonist, to highlight particular qualities and traits of the main character. This contrast can be in terms of personality, values, or behaviors and serves to enhance the audience's understanding of the protagonist's motivations and conflicts. The relationship between a foil and the protagonist or antagonist can illuminate key themes and character dynamics in a narrative.
