A foil is a fictional character that is envisioned to highpoint characteristics in another character through contrasting traits. It displays potentials that are in difference with the features of another character with an aim to highlight the traits of the other character. Examples of Foils are also found in plays. Foils aren’t certainly opposites; though, they highlight opposing traits. A literary foil may not be obvious at first instead progresses throughout a text. The foil character is used to focus some specific quality or qualities of the main character. A mutual literary foil is to portray a “good” character and a “bad” character. The good character’s traits lay importance on the bad character’s traits, and vice versa.
