The Alternate Dimension (ＡＤOrutanēto Dimenshon) is an archetype created by LHK. They are retrains of monsters that appeared in Yu-Gi-Oh! GX that appeared as non-card characters from episode 132 and onwards. They are the pioneers of a new mechanic, the Duality Monsters, as well as the Merger monsters, which are the Authorities. The archetype focuses on banishing, as well as changing "Dimensions" with the "Dimension" Field Spell Cards.
