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.
Counterpart Comparison: Ang and Ling seem to resemble an older Zuko and Azula from Avatar: The Last Airbender. The former are supposed to be fifteen (a year's difference at best to the latter) and were created after Avatar first aired, but the resemblance is striking.
Evil Is Sexy: Ling when she goes to the Yin (i.e. Dark) side. Can you believe that she is 15 years old? Check this out (She's the one on the right wearing the dark blue outfit).
Magnificent Bastard: An arguable case can be made for Master Chin, looking back on the fact that he keeps secrets from the twins that could probably have solved everything quickly if only he had told them. Hiding the truth about their father's death and their mother's existence is one example. Another is how he knew of the possibility of there being double golden dragons, but letting Ling go through her own path to this realisation. It is hard to decide if he is this trope or a Guile Hero.
Well, a Magnificent Bastard is mostly a villain. The character being described is not really a villain.
