List of unseen cards

This page lists cards that are known to exist, but which have not been shown in any Yu-Gi-Oh! media.

"Dark Knight" and "White Knight"
During an explanation of the Types of Magic Users in Duel Monsters, "Dark Knight" and "White Knight" were listed as examples of Black Magic and White Magic respectively.

"Blonde Wave"
In the manga, when Mai was reciting the cards Ryuzaki drew from the top of her Deck without looking, one of them was called "Blonde Wave".

"Ojamachine Green" and "Ojamachine Black"
These two cards are mentioned in the effect of "Mecha Ojama King." Nothing is known about them, apart from the fact that they can be Summoned by the effect of "Mecha Ojama King".

"Bishop" and "Knight"
These cards are mentioned in the effect text of "Promotion" as cards that can be Summoned with that card's effect by Tributing a "Puppet Pawn." Their names are presumably prefixed by "Puppet," though this is not stated on the card.

"Fire Dragon"
This card along with "Water Dragon" was seen in a Yu-Gi-Oh! GX opening in the possession of Bastion Misawa, but never appeared in the series proper.

"Mystic Baby Knight" and "Mystic Baby Magician"
These two cards are mentioned in the effect of "Mystic Revolution" as monsters that can be Tributed for the effect of "Mystic Revolution."

"Colorless, Chaos King of Dark World" and "Wicked Rune - Doubt"
Both cards were mentioned by Brron during his Duel with Jaden Yuki. The first card is as a monster that Brron intended to Summon with the effect of "Super Polymerization." Apart from that it is apparently a Fusion Monster, nothing is known about it, as Brron failed to complete the "Wicked Canon" to activate "Super Polymerization". The second one has the same effect as the other "Wicked Rune" cards. It was supposed to be the final part of completing "Super Polymerization", but wasn't played since Syrus escaped from Brron's minions.

"Super Fusion God"
This card is mentioned as a monster Yubel intends to Summon to unite the twelve Duel Spirit Dimensions into one. Yubel uses "Super Polymerization" and "Chain Material" to fuse one monster of each Level from 1 to 12 into this monster, but Jaden chains "Spiritual Fusion", fusing the souls of Yubel and himself instead.

"Cosmic Blazar Dragon"
This card was owned by Yusei Fudo in an alternate future where Z-one didn't interfere.
