Playing With: Evil-Detecting Dog

Basic Trope: Animals have the ability to detect evil and/or supernatural beings.
  • Straight: Rydia has a pet dragon, Torch, that growls when Baron Veli comes around.
  • Exaggerated: Rydia has a pet dragon, Torch, that burns anyone to a crisp who has a hostile thought about its owner.
  • Downplayed: Rydia has a pet dragon, Torch, that refuses to acknowledge and generally snubs Baron Veli.
  • Justified:
    • A dog was a stray and can recognize a person who was cruel to it.
    • The aforementioned Torch has the magical ability to see people's intentions.
    • Baron Veli has made a Deal with the Devil, and Torch can actually smell the influence of evil on him.
  • Inverted:
  • Subverted:
    • Torch growls at a goblin, but it turns out he's just racist against goblins. Rydia never noticed before, because she'd never met a good goblin.
    • Alternatively, Rydia's best friend has joined the Masquerade, and Torch treats him/her the same way.
    • Torch is just indifferent to evil people.
  • Double Subverted:
    • Torch was right; that goblin was evil.
    • Rydia's best friend was Good All Along.
    • But then Torch is suddenly hostile to the villain.
  • Parodied: When Lord and Lady Dark enter a zoo, every single animal there starts making more noise than a heavy metal concert.
  • Zig Zagged: Torch doesn't growl at Baron Veli even though his evilness can be detected by devices. Then its revealed Veli just has the scent of evil clung to him. Thus once Baron Veli becomes truly evil Torch growls at him. Yet when the Dark Lord makes an appearance...
  • Averted: None of the animals in a work have a predefined reaction to people based on alignment, and individual animals all act differently.
  • Enforced: "We need to show evil how Baron Veli is to the viewers. Have Rydia's dragon detect his evil."
  • Lampshaded: "Why does Buster always seem to spot the bad guys before we do?"
  • Invoked: "I'm not so sure about that Baron von Goodguy... somebody go get a dog."
  • Exploited: A police K-9 unit uses their dogs to do all the detective work.
  • Defied: "Seriously, you don't trust me because your dog barked at me? Excuse me, I'm off to find a hero with a bit of brains."
  • Discussed: "If this was a TV show we could find out who the spy for the Dark Lord is by seeing who Rover doesn't like."
  • Conversed:"Have you ever noticed that animals are very good at spotting bad guys?"
  • Deconstructed:
  • Reconstructed: Even though this setting has Black and Grey Morality, the animals only respond to the worst of the worst.

I don't like it here, it's making Rover nervous. Let's head back to Evil-Detecting Dog.
