Johnson's opponent was Joey Wheeler, while Leichter—who took the form of "Jinzo" to act as his Deck Master—was Seto Kaiba's opponent. Both of these Deck Masters have an effect to destroy cards the opponent controls of a certain type, are Level 6, and have 1500 DEF.
This monster has been shown several times in a full-body view, but rarely consistently. When Summoned by Seto Kaiba in the manga and in the first episode, it had red armor that covered its entire body, a purple cape hanging off its back, two small morningstars, and very squat, distorted proportions. In Yu-Gi-Oh! The Duelists of the Roses, the armor became purple, the cape was removed, and the morningstars became significantly larger, bigger than its entire head. In Yu-Gi-Oh! 5D's World Championship 2010: Reverse of Arcadia, the breastplate of the armor changed from purple to indigo, and the design was far more elaborate than in Duelists of the Roses. When it appeared as Johnson's Deck Master, it had humanoid proportions, no visible morningstars, a grey breastplate over a dark blue robe, and a purple cloak hanging over its shoulders, a design that was also used in episode 167 and in the artwork of "Half or Nothing."
