New Generation was originally meant to be a full-on retool of the franchise, with a roster strictly comprised entirely of new characters. It was only later in development that it was decided to add Ryu and Ken into the roster. ‘’2nd Impact’’ would later add Akuma and Chun Li would join in ‘’Third Strike’’.
Gill's original design was to have him manipulate light and darkness. However, Capcom, for many reasons, decided to use the fire/ice alignment to showcase their spiffy new hardware. His secondary color is a reference to the original direction.note He still retains fire and ice control, however.
