Question

When a character is a foil in a story, what does he or she typically do?

Answer 1

In fiction, a foil is a character who contrasts with another character, usually the protagonist, to highlight particular qualities of the other character. In some cases, a subplot can be used as a foil to the main plot. This is especially true in the case of metafiction and the "story within a story" motif.

Answer 2

They are the protagonist in the story bud :)
