The title "D/D/D" stands for Different Dimension Demon. Prepare to get a good taste of the power of kings who subjugate alternate planes.

— Declan Akaba on the D/D/D.

"D/D/D", known as DDD (Ｄ（ディー）Ｄ（ディー）Ｄ（ディー） DīDīDī) in the English manga, is an sub-archetype of the "D/D" archetype used by Declan Akaba in the special Yu-Gi-Oh! ARC-V chapter and anime. The "D/D/D" monsters serve as the "bosses" of the "D/D" due to most of their gameplay focusing on their summoning.

Design

So far, every "D/D/D" monster has been named after a historical military leader, except "D/D/D Hell Armageddon the Cruel End Overlord", "D/D/D Twin Dawn King Kali Yuga", and "D/D/D Oblivion King Abyss Ragnarok", which are named after mythical final battles.

Dragon King Pendragon	Uther Pendragon OR Arthur Pendragon
Gale King Alexander	Alexander III of Macedon

Etymology

According to Declan Akaba, "D/D/D" is short for "Different Dimension Demon" (ディファレント・ディメンション・デーモン Difarento Dimenshon Dēmon). The "D/D/D" archetype marks the first time that monsters with the word "Demon" (or "Daemon") in their names are released in the TCG, with said word intact. However since the word "Demon" is simply represented in the card names via an acronym, the use of this word is comparatively subtle.
