Foil
Explanation and Analysis—Opposites Collide:

Marie-Laure and Werner are apparent foils for one another, positioned as polar opposites by their respective cultures. Werner is an orphan; Marie-Laure has a loving father. Werner can see; Marie-Laure is blind. Werner is German and a soldier; Marie-Laure is French and sees her country invaded by Werner and his peers. Yet as the novel progresses towards the two characters' eventual meeting, they appear more similar than different, united by shared imagination, fate, and random chance.
