I'm in the process of creating my characters and want to make sure I properly avoid making them mary sues or gary stus. Right now I'm brainstorming their flaws. I hate character "flaws" that are nail biting or clumsiness because those are not flaws to me. I need some help brainstorming realistic flaws. I don't want the flaws to define the character in a way to make them unlikeable, but I do want flaws that can present the character's with self-inflicted problems or give them a reason to mature and overcome the flaw. What kind of flaws are redeemable and which ones pass the moral event horizon? What flaws are not really flaws and lead to mary sues and which ones make a character seem relatable and realistic?
