series Real Bout Fatal Fury Special and Real Bout Fatal Fury 2: The Newcomers which do not contain a storyline. In the PlayStation version from Real Bout Fatal Fury Special, Billy is brainwashed by his half-brother White in order to aid him in the conquer from Southtown. He then appears as a sub-boss character in the arcade mode, but once he is defeated, he returns to normal. A 3D fighting game version of the series, Fatal Fury: Wild Ambition was produced as well, which retells the plot of the first game. In The King of Fighters series, Billy was meant to appear in the first game from the series as a member of an England Team, composed of him, Mai Shiranui, and Big Bear, but due to several problems with the capacity of the game, and the desire from the Art of Fighting staff to add Yuri Sakazaki, Billy was removed from the game.
