"Nightmare's Steelcage":

Yu-Gi-Oh![edit]

In episode 65, Strings uses this card during his Duel against Yami Yugi while the former was possessed by Marik Ishtar. He activates this card so that Yugi could not attack and destroy any "Slime Tokens" that Strings would summon through the effect of "Jam Breeding Machine". In the next episode, Strings finally manages to summon "Slifer the Sky Dragon. After Yami Yugi summons "Kuriboh" and ends his turn, this card's effect expired.

In episode 74, this card appears in a flashback Yami Yugi has when he reminds Seto Kaiba that he saw a Rare Hunter being possessed by Marik.

In episode 79, Bonz uses this card during his Duel against Yami Bakura. He uses this card in an attempt to prevent Yami Bakura from attacking with "The Earl of Demise" for two turns. Despite this, Yami Bakura activates "Ectoplasmer" to bypass this card's effect and win the duel.

In episode 88, this card appears in a flashback Marik has when he remembers having his Rare Hunters test out the counterfeit versions of "The Winged Dragon of Ra". As they were counterfeits, the fake cards only caused the Rare Hunters to be killed by a bolt of lightning.

In episode 85, this card appears in a flashback Maximillion Pegasus has when he explains to Jaden Yuki in the past, people have been trying to playing counterfeit copies of "The Winged Dragon of Ra". These resulted in the people getting struck by lightning due to them invoking Ra's wrath.

In episode 9, this card is shown in Yusei Fudo's hand during his Ground Duel against Mr. Armstrong. In the next episode, Yusei activates this card to prevent both players from attacking for two turns. Mr. Armstrong finds a way around this by activating "Poison Chain" and "Paralyzing Chain" which forces Yusei to send cards from the top of his Deck to the Graveyard equal to the combined Levels of the "Iron Chain" monsters on Armstrong's side of the field and take 300 damage each time he is forced to send cards from his Deck to the Graveyard. Two turns after this card was activated, its effect expires.
- In the second above-mentioned episode, this card is shown when the effect of "Blasting the Ruins" activates.
- There was an error in both versions of episode 9 that showed that Yusei had two copies of this card. This is an error due to what we see in his hand in the next episode.

This card appears in Paradox's explanation when he tells Yugi, Jaden, and Yusei that the reason why he came to the past was so that he could prevent his own bad future from happening. Yugi, Jaden, and Yusei disagreed with going along with Paradox's plan as Paradox's actions will destroy and ruin their eras in time since they revolved around Duel Monsters.
