• Behemoth is the name of an ancient beast first described in the Book of Job.
  • This was once the only Dragon to be Limited.
    • Unlike most other Forbidden, Limited and Semi-Limited cards, this card was Limited not because of its power, but because of its once per Duel restriction. Before the ruling and text change which would make it apply to all copies of the card, the restriction applied only to individual copies, so it would be impossible to keep track of which copy had used its effect already if any were shuffled back into the Deck and drawn again. It was Limited to prevent this.
  • This card was the first card whose effect could only be used once per Duel.
