These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Mary Sue: Arguably. A few quotes from the author about Mary Sues:
Have you ever created a Mary Sue/Gary Stu/godmoding character? I think? They still just happen to blend into everything.
Just took this Mary Sue litmus test on the "Business Magnet" character, and got 78. (But since nearly every other character that I even fail to recognize as a Sue gets more points, that's moderately okay.)
Ron the Death Eater: Portal: The 4th Millennium franchise should get a prize for turning a Heroic Mime into the main antagonistic character (as far as protagonists and antagonists go there).
