Yu-Gi-Oh! Duel Monsters GX Edo is a skilled duelist who frequently attends Duel Academy. He has an intense desire to demonstrate that Judai is not truly a proficient player, and he claims that Judai copied his deck concepts. In many ways, Edos interacts with an enigmatic individual named Saiou. He believes that fate plays a significant role in dueling and asserts that the next "King Of Games" will emerge from hell.
Edos's deck revolves around a series of distinctive "Hero" cards, which differ significantly from Judai's. These rare themed Heroes were designed by Edos' missing father. Inspired by tales of British literature, Edos' deck is composed of "Destiny Heroes." Each Destiny Hero possesses unique abilities that alter the course of the game.
