The Head Shadows are a very small Archetype used by Yamoto. They consist of Mono-Head Shadow, Dual-Head Shadow, Tri-Head Shadow, and Quad-Head Shadow. Mono, Dual, and Tri-Head have the ability to be Special Summoned from your Deck in Attack Position when you Special Summon a DARK monster of a certain Level. Quad-Head, however, can be Special Summoned if you control 3 differently-named "Head Shadows", which is the only reason this series is an Archetype. Comibned with the other three, they can all be Special Summoned in one turn. Starting with Mono-Head, each monster gains 3 Levels, 500 ATK, and 1000 DEF for each head added on.
