All Signer Dragons have been featured on the anime. All Signer Dragons have been release in the [[OCG]]. However, five out of the six Signer Dragons have been released in the [[TCG]]. They are: "[[Stardust Dragon]]", "[[Red Dragon Archfiend]]", "[[Black Rose Dragon]]", "[[Ancient Fairy Dragon]]", and "[[Black-Winged Dragon]]".

In the anime, [[Professor Fudo]] gave the "[[Stardust Dragon]]", "[[Red Dragon Archfiend]]", and "[[Black Rose Dragon]]" [[Duel Monsters]] cards to [[Rex Goodwin]]. These three cards, along with the missing "[[Ancient Fairy Dragon]]" card, were originally designed so that their corresponding Signer could activate the safety switches for the [[Ener-D]] system.
