Joey can be met and dueled since the very beginning of the game, at any time of the day. He is also the first opponent the player faces in the Beginner Cup, and helps the player reclaim their prize after it is stolen.

After the player defeats a specific Rare Hunter, Joey will be brainwashed by Marik. He will have a total of two Shadow Games with the player at different times, the second of which must end in a draw to continue the game. During this time, he cannot be dueled normally.
