But if you'd like to take on a Tamora Pierce fanfic, there's at least one per page in the Pit. I think I can handle this alone-- the characters don't seem -too- badly banged up, though Alan might need exorcism towards the end, and the minis might get out of control.

Seriously, though? The quickest sure-fire way to find a Sue in most well-known fandoms is to search the Pit with a keyword like Crystal, or Starfire, or Fate, or something like that. You'll wind up with more than you can even begin to sort through, if that's what you're looking for.
