A Mary Sue (and the male equivalent, sometimes called a Gary Stu) is a character who is implausibly perfect — exceptionally talented, beautiful, beloved by everyone, and lacking meaningful flaws or genuine struggle. Things come too easily to them, and the story bends to make them succeed and be admired. Originating in fan-fiction criticism, the term names a wish-fulfillment character who fails to engage readers. The remedy is real flaws, genuine stakes and obstacles, and success that is earned rather than granted.
Chapter i·Why it matters
The Mary Sue is a useful concept for diagnosing a common character weakness: a protagonist so idealized and unchallenged that readers cannot connect with or root for them. Flawless characters are boring because struggle and imperfection are what create engagement and stakes. Understanding the Mary Sue — and that the fix is flaws, obstacles, and earned achievement — helps writers build protagonists who feel human and compelling rather than hollow wish fulfillment.

Chapter iii·Example
A writer realizes her protagonist is a Mary Sue — brilliant, beautiful, universally adored, succeeding at everything without struggle, with the story bending to favor her. Readers find her hollow. The writer gives her real flaws, genuine obstacles, and failures to overcome, so her eventual success is earned and she becomes someone readers actually root for.
