Tragic pastHaha, im skipping traits for a reason. Trust me, itll make sence in time.
So, Mary sues have tragic pasts, right? Can they still be flawless? Unless that made them flawless...
This makes me laugh every time.
You see, if one was truly flawless, past would be perfect. Happy, boring... Annoying.. kinda "whats the point?" senario.
See, forget physical (appearence, strength.. others i may miss...), but mental health. You see, bad past- throw in some PTSD or something, and, depending on the backstory, it can be triggered in a fight.
