'''''Different Dimension (D.D.)''''' is a name given to a series of cards all starting with either 'D.D.' or 'Different Dimension'. These cards focus on removing cards from play, often on their demise, thus sending them to a 'Different Dimension' rather then simply destroying the other monster. They can use those monsters to get more powerful or gain special effects. Although they were released in different sets, a large amount of 'Different Dimension' monsters were released in [[Structure Deck: The Dark Emperor]]

There are also cards that help removing at the same time that represent a defense for you as [[Dimensional Prison]], [[D.D. Trap Hole]], [[D.D. Survivor]], [[D.D. Scout Plane]], etc.
