===Appearance===

The regular "D/D" monsters seem to be based on different figures and monsters from Western mythology, while the "D/D Savant" monsters are references to great natural scientists from Western history. In contrast, the "[[D/D/D]]" sub-archetype features a distinct design style from the rest of the archetype, with many of its members modeled after famous conquerors from world history.

Additionally, some of the archetype's boss monsters such as "[[D/D/D Doom King Armageddon]]" feature a pun in its Japanese name, such as "''Great Des (Death) King''" being scripted as "''Shiiō''", a homophone for "[[wikipedia:Chief executive officer|CEO]]". A similar pun can be found in the Japanese name of "[[D/D/D Oblivion King Abyss Ragnarok]]" and "[[D/D/D Wave Oblivion King Caesar Ragnarok]]", "''Oblivion King''", which is scripted as "''Kaichiō''", a homophone for "[[wikipedia:Chairman|Chairman]]".

In the [[Yu-Gi-Oh! ARC-V (manga)|ARC-V manga]], the "D/D" monsters appear to be demons with a mechanical, scientific theme (distinct in design to the "D/D Savant" monsters) and have equipment like scales or microscopes instead of faces.

===Etymology===

According to [[Sora Perse]], "D/D" is short for "Different Dimension" (ディファレント・ディメンション ''Difarento Dimenshon''), the same as the [[D.D.]] series.<!--Please do not add comparisons with "D.D."; You would be comparing an English name ("D.D.") with a Japanese name ("DD"). Also, "D.D." is ''not'' an archetype.--><ref name="ep12">{{episode|Yu-Gi-Oh! ARC-V|12|ref}}</ref>

==Members==

"D/D" monsters tend to vary based on the medium in which they were introduced. Two of the "D/D" subseries, "D/D Savant" and "D/D Surveyor", have distinct origins from the other "D/D" monsters introduced in the same medium.

** The "D/D Surveyor" series, which originated in the manga, are based on various types of measuring and observational equipment.

* The two "D/D" monsters introduced in the ''[[Yu-Gi-Oh! ARC-V - Scale SP1|Special One-Shot]]'' manga ("Proud Chevalier" and "Proud Ogre") function as a distinct duo, not following any of the patterns from other media.

==Playing style==

The archetype's primary play-style is to use the beneficial effects of its various [[Pendulum Monster]]s and "[[Dark Contract]]" [[Continuous Spell Card|Continuous Spells]] and [[Continuous Trap Card|Traps]] to gain card advantage while also trying to avoid the [[LP]] damage with the effects of "[[D/D/D Oracle King d'Arc]]", "[[D/D/D Rebel King Leonidas]]" and/or "[[Go! - D/D/D Divine Zero King Rage]]", or remove the "Dark Contract" cards from the [[field]] (after completing the card's combo) with the effects of other members. Managing these cards properly is essential to victory.
