Mary Sue

A "Mary Sue" is a term often used in storytelling, particularly in fan fiction, to describe a character who is overly idealized and lacks realistic flaws. This character typically possesses extraordinary talents, beauty, and charm, making them universally admired or successful without sufficient struggle or development. The name originated from a character in a 1970s parodic story. While Mary Sues can be entertaining, they can detract from a narrative if they disrupt balance or relatability, making it difficult for audiences to connect with the character's experiences.
