Mary Sue and Gary Stu: Bad Character Writing


INFO.FIKSI.NET — When analyzing books, movies, or TV shows, you might come across characters who seem too perfect—unrealistically skilled, universally loved, or lacking meaningful flaws. These characters are often called Mary Sues (for female characters) or Gary Stus (for male characters).

But what exactly makes a character a Mary Sue or Gary Stu? And why do they matter in storytelling? Let’s break it down.

What Is a Mary Sue/Gary Stu?

A Mary Sue (or Gary Stu, also known as Marty Stu) is a character who is unrealistically flawless, often bending the story’s logic to make them the center of attention. These characters typically:

  1. Excel at everything (combat, intelligence, charm, etc.) with little to no training.
  2. Are adored by everyone (or hated for no good reason, making them a "misunderstood genius").
  3. Lack meaningful flaws—or their "flaws" are superficial (e.g., "too kind" or "too beautiful").
  4. Warp the story around them, making other characters act unrealistically to serve their narrative.
  5. Often serve as a wish-fulfillment fantasy for the author rather than a well-developed character.

The term "Mary Sue" originated from a 1973 Star Trek fanfiction parody about a young, perfect officer who outshone even the main cast. Since then, it has become a widely used critique in storytelling.


Why Are Mary Sues/Gary Stus Problematic?

While there’s nothing wrong with powerful or heroic characters, Mary Sues and Gary Stus can weaken a story because:
  1. They Lack Depth – A character without real struggles or growth feels hollow.
  2. They Reduce Tension – If a character never fails or faces consequences, the stakes feel low.
  3. They Overshadow Others – Side characters may become one-dimensional just to prop up the Sue/Stu.
  4. They Break Immersion – When a character defies logic (e.g., a rookie defeating a master villain effortlessly), it feels unrealistic.


However, not all-powerful characters are Mary Sues—what matters is how they fit into the narrative. For example:
  • Anakin Skywalker (Star Wars Prequels) – Though powerful, his arrogance and eventual downfall make him flawed.
  • Rey (Star Wars Sequel Trilogy) – Often criticized as a Mary Sue due to her rapid mastery of the Force with minimal training.
  • Bella Swan (Twilight) – Considered a Mary Sue because every major character is obsessed with her without much justification.

How to Avoid Writing a Mary Sue/Gary Stu

If you're a writer (or just analyzing stories), here’s how to spot or prevent Mary Sue traits:

Give them real flaws – Not just "clumsiness," but traits that genuinely hinder them.
Let them fail and grow – A character should earn their skills through struggle.
Make relationships feel earned – Other characters shouldn’t love/hate them without reason.
Keep the world consistent – The story shouldn’t bend its rules just to favor them.



Conclusion: Are All Powerful Characters Mary Sues?

No. Characters like Sherlock Holmes, James Bond, or Wonder Woman are highly skilled but avoid being Sues/Stus because:

  1. They have defined weaknesses (e.g., Sherlock’s social ineptitude).
  2. Their abilities are explained and consistent within their world.
  3. They face real consequences for their actions.

A Mary Sue/Gary Stu isn’t just about power—it’s about narrative imbalance. A well-written character, no matter how strong, should feel like a natural part of their stor


Final Thought

Next time you review a book, movie, or show, ask:

  • Does this character feel too perfect?
  • Do other characters act unrealistically around them?
  • Are their struggles and victories earned?

If the answer is "yes" too often, you might be dealing with a Mary Sue or Gary Stu!
