Changes

The majority of the series are [[Dragon]]-[[Type]] [[Synchro Monster]]s (the exceptions are "[[Power Tool Mecha Dragon]]", which is a [[Machine]]-Type, and "[[Dragonecro Nethersoul Dragon]]", which is a [[Fusion Monster]]). "Duel Dragons" with "Signed Signer Dragon" counterparts display markings that seem to evoke the [[Mark of the Dragon]] somewhere on their bodies. "Duel Dragons" distributed by Skeleton Knight, as well as Skeleton Knight's and Rex Goodwin's Dragons, do not possess these markings. Both "Power Tool Mecha Dragon" and "[[Ancient Pixie Dragon]]", which resemble their anime counterparts, can be considered [[dark counterpart]]s due to their [[DARK]] [[Attribute]]s and alternate effects.

The "Duel Dragons" which are "Signer Dragon" counterparts often have a darker color scheme than the original, though "[[Stardust Spark Dragon]]" and "[[Blackfeather Darkrage Dragon]]" only demonstrated this when being used by the [[Priests of Light|Priest of Light]] and [[Dark Crow Hogan|Dark Crow]] respectively. [[Jack Atlas (manga)|Jack]]'s "[[Hot Red Dragon Archfiend]]" does not appear to exhibit a darker color scheme, but this is difficult to discern to due to the natural color of the "Duel Dragon". Both "Power Tool Mecha Dragon" and "Ancient Pixie Dragon" exhibited darker color schemes while [[Leo (manga)|Leo]] and [[Luna (manga)|Luna]] were possessed by their Dragons' Shadow Miasma; after both Dragons were purified by "Stardust Spark Dragon", they assumed the same color scheme as their original counterparts.
