TL;DR

Marty Stu

—noun

A male character that is unrealistically perfect or excessively ideal, to the point of undermining the story.

What is a Marty Stu in online roleplay?

Marty Stu is a term used to describe a male character in fanfiction and roleplaying games (RPGs) who is portrayed as excessively ideal, lacking flaws, or unrealistically powerful, to the point where it undermines the game’s narrative credibility.

Marty Stu characters are typically flawless, succeed at almost everything they attempt, and overshadow other characters.

In text-based RPGs, this can manifest through narrative decisions, dialogue, and character interactions that highlight the Marty Stu’s superiority over others and the game setting.

Marty Stu’s are not unique to text-based RPGs but are prevalent in many storytelling mediums.

They are especially noticeable in games that emphasize roleplaying and character development, where balance and character flaws contribute significantly to the story’s depth and believability.

Types of games where the term is commonly used include:

MUD, MUSH, RPMUD, PbP, Chat RPG, Social media RPG, RPI, RPE, MMORPG.

Myths and misconceptions

There are several myths about these characters that can lead to misunderstandings:

  1. All powerful characters are Marty Stus: Not true. Characters can be powerful yet still have flaws, challenges, and limitations that prevent them from being Marty Stus.
  2. Marty Stus are only a problem in amateur writing: This is a misconception. Marty Stus can appear in any level of storytelling, from professional works to casual games. They can appear in screenplays, fanfiction, and RP.
  3. Adding a tragic backstory prevents a character from being a Marty Stu: Simply giving a character a sad past does not automatically give them depth or prevent them from being a Marty Stu if they lack realistic traits and challenges.
  4. A Marty Stu is just a male Mary Sue with no differences: While the terms are related, the way these characters are written or perceived can be influenced by genre conventions and audience expectations. Marty Stus are often shaped by different tropes than their Mary Sue counterparts.
  5. Marty Stus are always intentional creations by their writers: Sometimes, a writer unintentionally creates a Marty Stu by not recognizing the lack of character flaws or narrative balance. Most instances are not a result of deliberate choices.
