Enhance Dimension

The Enhance Dimension (エンハンス次元 Enhansu Jigen) is the Dimension where all Duelists use Enhance Monsters. Unlike the rest of the Dimensions, inhabitants of the Enhance Dimension are not completely the same as normal humans, since their outfit looks like they are armed with some metal clothing that protects them. That's the reason why most inhabitants of that dimension can survive strong attacks that other duelists from other dimensions cannot.

As stated by Yuki, 's counterpart in this Dimension, Enhance Dimension inhabitants are "built-to-last", implying that their clothing works as a shield to hold off different attacks, either from monsters in battle, or by invaders of this Dimension.
