Card Appearances:Kozaky
- Kozaky was a Duel Monsters spirit in Yu-Gi-Oh! GX that dueled against Jim when the latter and Axel were trying to find Jaden Yuki. Jim defeated Kozaky and he was crushed by the parts of his destroyed monsters.
- In Yu-Gi-Oh! World Championship 2008, he appears as a Duel Spirit, and you duel against many of his creations, including the Inpachi monsters and Giga Gagagigo. He claims to be the creator of an out-of-control Blowback Dragon that you also defeat. His own deck focuses on the use of Light and Darkness Dragon, since, oddly, the game does not have the Kozaky or Giant Kozaky cards.
