In literature, "impostor" serves as a versatile label for characters whose legitimacy or moral standing is in doubt. It is used to denounce those who wear masks of honor while acting with deceit, as when a character is condemned as an "unprincipled impostor" ([1]), or when an impostor is expelled to restore order, as seen in Homer’s narrative ([2]). Authors also employ the term to challenge identity and credibility, whether by exposing a political manipulator ([3]) or hinting at the internal struggle of self-recognition and dishonesty ([4], [5]). The word frequently underscores themes of fraud, artifice, and the blurred lines between truth and pretense throughout diverse literary traditions.
