D/D/D/D ((ディー)(ディー)(ディー)(ディー) DīDīDīDī) is a sub-Archetype of the "D/D/D" Archetype, and is thus a further sub-Archetype of the "D/D" Archetype. They are stated to be Reiji Akaba's true power.

According to Taylor Gorrell, "D/D/D/D" is short for "Different Dimension Daemon Dragon" (ディファレント・ディメンション・デーモン・ドラゴン Difarento Dimenshon Dēmon Doragon), and as such, all "D/D/D/D" monsters have primarily dragonic forms and are treated as Dragon-Type monsters in addition to their printed Fiend-Type.


All "D/D/D/D" monsters are evolutions of the "D/D/D" monster respective to their secondary Type, sharing their Attribute and being Summoned by the evolution of whatever Summon their original form was Summoned by, usually requiring their original form as a Material. Their actual names are two words, the first word being a synonym for the Underworld or Hell from a different mythology, and the second word being a word related to their element or otherwise.
