Funny enough, this phrase was coined in a fan-fiction. And if you don’t know what fan-fiction is, I think you are better off, but it’s just as the name suggests. It’s stories people write off of established books, movies, games, etc. Fanfiction has no bounds, but it’s also very scary, so tread carefully.

If you’re throwing soft balls at your characters then it won’t hurt when your reader is reading. They won’t even know if they’re getting hit with anything.

Mary Sue is kinda a copy and paste perfect person but I think it’s just as when the author writes a copy and paste version of another character that has the same flaws and…
