"Forbidden", known as "Prohibited Holy" (禁(きん)じられた Kinjirareta) in the OCG, is a series of Quick-Play Spell Cards sharing similar artworks and effects. Their artworks all feature a white-clothed woman holding various items, in a place that appears to be "The Sanctuary in the Sky". The first member of the series ("Forbidden Chalice") was released in Raging Battle, then more members came in the Storm of Ragnarok and Abyss Rising sets.

So far, all the "Forbidden" cards focus on manipulating monsters' ATK points and card effects, either by granting monsters immunity or by negating their effects.

Trivia

• Despite the Grecian theme and appearance of each of the cards' artwork, the inspiration behind the series could come from the holy 3 most notable relics in Christianity and Christian mythos; the Holy Grail ("Forbidden Chalice"), the Spear of Longinus or Spear of Destiny ("Forbidden Lance"), and the Seamless Robe of Jesus ("Forbidden Garment").
• It is very likely that the woman featured in each card's artwork represents Pandora of Greek mythology.
