- In The Black Thief and the Knight of the Glen, the title thief is a thief. Nevertheless, he generously throws his lot in with the three princes to help them, and in the course of the tale, he reveals that he saved the knight's life as a baby at considerable danger to himself.
- The original tale of The Little Mermaid had the Witch as not being evil, just neutral and clearly warning of the risks. In at least some versions, she even informs the mermaid's sisters about how to save her.

- According to Alpine folklore, the demonic goat figure Krampus is the polar opposite of Santa Claus in that while Santa rewards good children with gifts, Krampus punishes naughty children using harsh punishments. It's because of this that he's often depicted as a good guy within countries that honor Krampus-related traditions in spite of him being a goat demon (although you might not get that within certain works of fiction).
