It's possible you're thinking of a different card or have misremembered the name. Could you provide more details about the card you're looking for, such as:
* What is the card's effect?
* What type of monster is it (e.g., Warrior, Spellcaster)?
* What is the card's artwork like?
With more information, I might be able to help you find the card you're looking for and determine which GX booster pack it was released in.
