Mary Sue

/ˈmɛri suː/

Common

An idealized character who is unrealistically perfect, solves every problem effortlessly, and faces no meaningful consequences.

The term is contested. It is sometimes applied fairly to flat, wish-fulfillment characters. It is also misapplied to competent female characters simply because they succeed. The word carries baggage.

  • A character's abilities seem to exist purely to make them look good, not to serve the story.

Do not use it when
