"D/D/D" (Ｄ（ディー）Ｄ（ディー）Ｄ（ディー） DīDīDī), known as DDD in English manga, and pronounced "Triple D" in the dubbed anime, is a sub-archetype of the "D/D" archetype used by Declan Akaba in the Yu-Gi-Oh! ARC-V anime and special manga chapter. The "D/D/D" monsters serve as the "bosses" of the "D/D" archetype due to most of the archetype's gameplay focusing on their summoning, along with the fact that "D/D/D" monsters generally have higher ATK and DEF and stronger effects than non "D/D/D" "D/D" monsters.
