Four trick-or-treaters dressed up as Batman, John Constantine, Zatanna, and Doctor Fate run afoul of the House of Mystery and Klarion the Witch Boy.
This episode provides examples of the following tropes:
- Chekhov's Gun: During the final battle, the heroes use the candy they obtained earlier to good use, like Zatanna using her toothbrush to unclog her mouth.
- Halloween Episode
- The Mirror Shows Your True Self: How the four kids realize they're the real deal when they come into contact with one.
- Prequel: At the end of the story, Constantine gains possession of the House of Mystery.
- Tomato Surprise: Turns out the kids dressing up as super heroes are in fact the real deal: they were de-aged and had their memories erased by Klarion.
- The Voiceless: While Fate does have lines, it's only in his kid form. His adult self doesn't speak at all.
