Card Trivia:ZW - Ultimate Shield
- Like fellow "ZW -" monsters ("Lightning Blade" and "Tornado Bringer"), this monster is not named for the creature it is based off, this case being a black tortoise.
- This card, like "ZW - Leo Arms", equips to "Number C39: Utopia Ray" not from the hand, but from your side of the field.
- This card may be made to resemble a sea turtle. The reason for this is, keeping with mythical beasts, the tortoise is considered one of four heavenly beasts (along with the Dragon ("Tornado Bringer"), Tiger ("Lightning Blade") and Phoenix ("Phoenix Bow").
- This card's arwork somewhat resembles that of "Morphtronic" monsters.
