Folier används i alla typer av litteratur. Ett tecken som uppvisar motsatta eller motstridiga egenskaper till en annan karaktär kallas en folie. Folie tecken kan vara antagonister, men inte alltid. Ibland kommer folier till och med andra tecken bredvid huvudpersonen. När en författare använder en folie vill de se till att läsaren plockar upp viktiga attribut och egenskaper hos huvudpersonen. Av denna anledning är folier viktiga att se upp för!
