Yu-Gi-Oh! Duel Monsters GX

In many ways, he involves himself with a mysterious person named, Saiou. He believes that Destiny plays a role in dueling and that he'll become the next "King Of Games."
Edo's deck is focused around a special series of "Hero" cards. These cards unlike Judai's are DARK monsters. The rare themed DARK Heroes were designed by Edo's missing father. Based upon tales of British literature, Edo's deck is made up of "Destiny Hero"s. The Destiny Heroes each have unique abilities that change the way the game is played.
Edo's father was killed when DD broke into his residence to steal a card named Destiny HERO Bloo-D. Leaving Edo an orphan.
