* InterchangeableAsianCultures: For some reason a sizable amount of characters use Japanese weapons ([[KatanasAreBetter usually katanas]]), despite the fact that the series is set in China, is about Chinese mythology, and none of the characters who use Japanese weapons have any connections whatsoever to Japan.
* MagnificentBastard: The Demon King. Granted, it's probably in the job description. [[spoiler: The climax of Heaven to Wudang drives the point home.]]
* {{Squick}}: Was it really necessary to describe turtle sexuality in ''Demon Child''?
