A masquerade is a Trope (literature) that is used to conceal the identity and certain characteristics of a figure.[1] This concealment has the effect of highlighting some unique or noteworthy aspect of a character or situation, despite its suggested intention of subtlety.[1] There exists the true nature of a character or situation alongside the image that is outwardly displayed and perceived by others in that universe, which can create a layered complexity that adds depth and dimension to the narrative.[1]
The historical traces of this term extend deeply throughout history and its influence on the texts in which appears becomes increasingly more dynamic and a variety of genres take advantage of the masquerade trope. It's popularly employed in the fantasy and superhero genres, but there are other instances in which it can be found across various fictional works.
