Card Trivia:Iron Cage
- This card is based on the iron cage from the fairy tale, Iron John, in which the titular enchanted wild man is imprisoned by the king and imprisoned in a castle courtyard. Years later, a young prince frees him, and Iron John takes the prince away from his kingdom to escape the death penalty for releasing him.
- In the Yu-Gi-Oh! anime, the cage imprisons the targeted monster, causing it to disappear for one turn until it eventually "releases" the targeted monster. Fittingly, in Yu-Gi-Oh! episode Sinister Secrets, Part 2", this card was used to destroy " 197: "Iron Hans", a monster based on Iron John from the titular fairy tale who was imprisoned inside the iron cage.
