Card Trivia:Clock Tower Prison
- This card is based on the Elizabeth Tower, which is more commonly referred to as Big Ben, keeping in relation with the European theme of the "Destiny HERO" archetype.
- In the Yu-Gi-Oh! GX anime, the materialized clock tower is shown to strike the hours of 3:00, 6:00, and 9:00 for each Clock Counter placed on this card. When the fourth Clock Counter is placed, the clock strikes 12:00 and vibrates ominously.
- This card's effect of Special Summoning "Destiny HERO - Dreadmaster" is a reference to the Man in the Iron Mask, an unknown prisoner who was arrested in the late 17th century and held in various French prisons.
- This card is the first Field Spell Card to have an effect that applies exclusively to its controller.
