Beta is a character appearing in Yu-Gi-Oh! 5D's World Championship 2009: Stardust Accelerator. Beta is one of the clones of the player and as such takes on their appearance.
The player must face all four clones, Alpha, Beta, Gamma and Delta in order, without recovering Life Points between Duels, in the second-to-last event of the main storyline. After the four clones are defeated, they cannot be faced again.
If the game is hacked, or otherwise altered, to allow the player to duel the clones in World Championship Mode, they all appear as a red, crudely-drawn person.
