The Japenese name of this card refers to a mysterious word mentioned in a famous prophecy by Nostradamus, which detailed an event set to occur on July of 1999. Most experts on Nostradamus believed that the ominous prophecy foretold a tyrant coming to power in the Middle East who would start a war that would affect the entire world. The date passed without incident, so clearly, the prophecy was either wrong or misinterpreted.
This card's effect of inflicting damage equal to the difference of a monster's ATK before and after a change is similar to that of "Number 33: Chronomaly Machu Mech"; both these cards are owned by Trey.
In the anime, this card's true power is sucking everything into the Barian World.
