"Wicked Rune" (known as "Wicked Doctrine" (邪心教義, Jashin Kyōgi) in the Japanese version) is an archetype of cards used by Brron, Mad King of Dark World in the Yu-Gi-Oh! GX anime.

They are used to create the "Super Polymerization" by sacrificing Jaden's friends, each imbued with a different emotion.


Each of the Wicked Runes corresponds to one of the Duelists sacrificed by Brron (or, in Syrus' case, was going to sacrifice).
