Mary Sue and Gary Stu

Mary Sue= Mary Sue (also known as Gary Stu for the male counterparts) is a trope where a character is portrayed as a completely perfect person who is free from problems.

They're often used on characters who are important in the story, they possess unusual physical traits, and have an irrelevantly over-skilled or over-idealized nature.

Why This Trope Sucks

 * 1) It makes the character's personality very bland and makes them a lot less quirky compared to other characters who aren't Mary Sues or Gary Stus.
 * 2) They are literally portrayed as a perfect person that never makes mistakes and is free from all problems, which is very unrealistic, because no human or creature on earth is a perfect being who can do literally nothing wrong.
 * 3) Most of them barely have to suffer through any type of problem or issue that gets in their ways.
 * 4) For the most part, they can be extremely one-dimensional and lack that much character development.
 * 5) Sometimes, they can be portrayed as literal jerks and will brag about their Mary Sue/Gary Stu traits.

Redeeming Qualities

 * 1) There are a few Mary Sues and Gary Stus who are well-written characters, like Gwen Tennyson, Bob the Builder, Fireman Sam, Hello Kitty, Wendy, Postman Pat, etc.
 * 2) *Lots of the time, Mary Sues and Gary Stus can also be portrayed as friendly characters and are sometimes willing to give good morals to other characters.
 * 3) **Bob the Builder and Fireman Sam are very good examples, as Sam usually gives the characters fire safety tips in every episode whilst Bob usually gives the characters construction safety tips.
 * 4) Some of them do receive character development and can even be forced to hurdle through problems that they have to solve themselves.
